COMMUNICATION OUTLET WITH
SHUTTER MECHANISM AND WIRE MANAGER
BACKGROUND OF THE INVENTION
Field of the Invention
The present invention is directed generally to communication outlets.
Description of the Related Art
Conventional RJ-45 type outlets have several drawbacks. For
example, such outlets each include an opening configured to receive a
conventional
RJ-45 type plug. Unfortunately, debris and/or foreign objects (e.g., tools,
fingers,
etc.) may be received and/or inserted into that opening. Further, a
conventional RJ-
45 type outlet includes a carrier or terminal block with slots into which
wires are
pressed to terminate a cable. Unfortunately, it is difficult and time
consuming for
users to press the individual wires into each of the slots. Therefore, a need
exists for
improved RJ-45 type outlet designs. Outlets and devices configured to prevent
debris and objects other than a plug from being inserted into the plug-
receiving
opening are particularly desirable. Outlets to which cables may be more
readily
terminated are also desirable. The present application provides these and
other
advantages as will be apparent from the following detailed description and
accompanying figures.
SUMMARY OF THE INVENTION
An embodiment includes a first communication connector for use with a
cable having at least one grounding component. The first communication
connector
includes an electrically conductive housing door pivotably coupled to an
electrically
conductive housing having a door gripping portion. The housing door is
connectable
to the at least one grounding component to form an electrical connection
therewith.
The housing door is rotatable with respect to the housing between open and
closed
positions. A first one of the housing door and the door gripping portion has a
1

engages
the second one of the housing door and the door gripping portion. The
projection
may have a spherical cap shape.
The housing door may be a first housing door and the projection may
be a first projection. In such embodiments, the first communication connector
includes an electrically conductive second housing door pivotably coupled to
the
housing. The second housing door is connectable to the at least one grounding
component to form an electrical connection therewith. The second housing door
is
rotatable with respect to the housing between open and closed positions. A
third
one of the second housing door and the door gripping portion has a second
projection configured to engage a fourth one of the second housing door and
the
door gripping portion when the second housing door is in the closed position.
The
fourth one is different from the third one. The second projection is
configured to

DETAILED DESCRIPTION OF THE INVENTION
Figure 1 is a perspective view of an assembly or connection 10 that
includes a conventional RJ-45 type plug 100 mated with a communication outlet
120.
For ease of illustration, the plug receiving side of the outlet 120 will be
referred to as
the front of the outlet 120. Similarly, the portion of the plug 100 inserted
into the
outlet 120 will be referred to as the front of the plug 100. The outlet 120
terminates a
communication cable Cl and the plug 100 terminates a communication cable C2.
Thus, the connection 10 connects the cables Cl and C2 together.

PCT/US2016/056374
CABLES
The cables Cl and C2 may be substantially identical to one another.
For the sake of brevity, only the structure of the cable Cl will be described
in detail.
The cable Cl includes a drain wire JDW and a plurality of wires JW1-JW8. The
wires JW1-JW8 are arranged in four twisted-wire pairs (also known as "twisted
pairs"). The first twisted pair includes the wires JW4 and JW5. The second
twisted
pair includes the wires JW1 and JW2. The third twisted pair includes the wires
JW3
and JW6. The fourth twisted pair includes the wires JW7 and JW8.
Optionally, each of the twisted pairs may be housed inside a pair
shield. In the embodiment illustrated, the first twisted pair (wires JW4 and
JW5) is
housed inside a first pair shield JPS1, the second twisted pair (wires JW1 and
JW2)
is housed inside a second pair shield JPS2, the third twisted pair (wires JW3
and
JW6) is housed inside a third pair shield JPS3, the fourth twisted pair (wires
JW7
and JW8) is housed inside a fourth pair shield JPS4. For ease of illustration,
the
optional pair shields JPS1-JPS4 have been omitted from the other figures.
The drain wire JDW, the wires JW1-JW8, and the optional pair shields
JPS1-JPS4 are housed inside a cable shield 140J. The drain wire JDW, the
wires JW1-JW8, and the optional pair shields JPS1-JPS4 are each constructed
from
one or more electrically conductive materials.
The drain wire JDW, the wires JW1-JW8, the optional pair shields
JPS1-JPS4, and the cable shield 140J are housed inside a protective outer
cable
sheath or jacket 180J typically constructed from an electrically insulating
material.
Optionally, the cable Cl may include additional conventional cable
components (not shown) such as additional shielding, dividers, and the like.
Turning to Figure 2, each of the wires JW1-JW8 (see Figure 1) is
substantially identical to one another. For the sake of brevity, only the
structure of
the wire JW1 will be described. As is appreciated by those of ordinary skill
in the art,
the wire JW1 as well as the wires JW2-JW8 each includes an electrical
conductor 142 (e.g., a conventional copper wire) surrounded by an outer layer
of
insulation 144 (e.g., a conventional insulating flexible plastic jacket).

CA 03002040 2018-04-13
WO 2017/066163
PCT/US2016/056374
Returning to Figure 1, each of the twisted pairs serves as a conductor
of a differential signaling pair wherein signals are transmitted thereupon and
expressed as voltage and/or current differences between the wires of the
twisted
pair. A twisted pair can be susceptible to electromagnetic sources including
another
nearby cable of similar construction. Signals received by the twisted pair
from such
electromagnetic sources external to the cable's jacket (e.g., the jacket 180J)
are
referred to as alien crosstalk. The twisted pair can also receive signals from
one or
more wires of the three other twisted pairs within the cable's jacket, which
is referred
to as "local crosstalk" or "internal crosstalk."
As mentioned above, the cables Cl and C2 may be substantially
identical to one another. In the embodiment illustrated, the cable C2 includes
a drain
wire PDW, wires PW1-PW8, optional pair shields PPS1-PPS4, a cable shield 140P,
and a cable jacket 180P that are substantially identical to the drain wire
JDW, the
wires JW1-JW8, the optional pair shields JPS1-JPS4, the cable shield 140J, and
the
cable jacket 180J, respectively, of the cable Cl.
PLUG
Figure 3 is a perspective view of the plug 100 separated from the
outlet 120 (see Figure 1). Figure 4 is a perspective view showing a front
portion of
the plug 100 and a rear portion of the outlet 120. The plug 100 may be
inserted into
the outlet 120 in a direction identified by arrow Al to form the connection 10
depicted
in Figure 1.
As mentioned above, the plug 100 is a conventional RJ-45 type plug.
Thus, referring to Figure 3, the plug 100 includes a plug housing 150. The
housing 150 may be constructed of a conductive material (e.g., metal). In such
embodiments, referring to Figure 1, the drain wire PDW, the cable shield 140P,
and/or optional pair shields PPS1-PPS4 may contact the housing 150 and form an
electrical connection therewith.
Referring to Figure 3, the plug housing 150 is configured to house plug
contacts P1-P8. Each of the plug contacts P1-P8 is constructed from an
electrically
conductive material. Referring to Figure 1, inside the plug 100, the plug
contacts P1 -

PCT/US2016/056374
P8 (see Figure 3) are electrically connected to the wires PW1-PW8,
respectively, of
the cable C2.
Referring to Figure 3, the housing 150 has a forward portion 152
configured to be received by the outlet 120 (see Figure 4), and the forward
portion 152 has a forward facing portion 154. Openings 171-178 are formed in
the
forward portion 152 of the plug housing 150. The plug contacts P1-P8 are
positioned adjacent the openings 171-178, respectively. Referring to Figure 1,
when
the plug 100 is received by the outlet 120 to form the connection 10, outlet
contacts J1-J8 (see Figure 20) in the outlet 120 extend into the openings 171-
178
(see Figure 3), respectively, and contact the plug contacts P1-P8 (see Figure
3),
respectively. In the connection 10, the contacts P1-P8 (see Figure 3) form
physical
and electrical connections with the outlet contacts J1-J8 (see Figure 20),
respectively, of the outlet 120.
Referring to Figure 4, a conventional latch arm 160 is attached to the
housing 150. A portion 162 of the latch arm 160 extends onto the forward
facing
portion 154. The portion 162 extends forwardly from the forward facing portion
154
away from the housing 150.
OUTLET
Figure 5 is a perspective view showing a front portion of the outlet 120,
and Figures 6 and 7 are perspective views showing a rear portion of the outlet
120.
The cable Cl terminated by the outlet 120 has been omitted from Figures 5-7.
In the
embodiment illustrated, the outlet 120 is constructed to comply with the RJ-45
standard.
Figures 8-10 are exploded perspective views of the outlet 120.
Referring to Figures 8-10, the outlet 120 includes a face plate 310, a locking
shutter
subassembly 320, a housing 330, one or more ground springs 340A and 340B, a
plurality of resilient tines or outlet contacts 342, an optional spring
assembly 350, a
contact positioning member 352, a substrate 354 (depicted as a printed circuit
board), an optional clip or latch member 356, a plurality of wire contacts
360, a guide
sleeve 370, a wire manager 380, and housing doors 390 and 392. As may be
viewed in Figure 20, the outlet contacts 342 may include the outlet contacts
J1-J8.
CA 03002040 2018-04-13
WO 2017/066163
PCT/US2016/056374
As may be viewed in Figure 11, the wire contacts 360 may include eight wire
contacts 361-368. Together the outlet contacts 342, the optional spring
assembly 350, the contact positioning member 352, the substrate 354, and the
wire
contacts 360 may be characterized as forming a first embodiment of a contact
subassembly 358 configured for use with the other components of the outlet
120,
which include the face plate 310, the locking shutter subassembly 320, the
housing 330, the ground springs 340A and 340B, the optional latch member 356,
the
guide sleeve 370, the wire manager 380, and the housing doors 390 and 392.
Referring to Figures 8-10, the outlet 120 differs significantly from
conventional RJ-45 type outlets in several ways. For example, as mentioned in
the
Background Section, debris and/or foreign objects (e.g., tools, fingers, etc.)
may be
readily received and/or easily inserted into the plug receiving opening of a
conventional RJ-45 type outlet (not shown). In contrast, the locking shutter
subassembly 320 of the outlet 120 helps prevent debris and objects other than
the
plug 100 (see Figures 1, 3, and 4) from entering (or being pushed into) a plug
receiving opening 312 (formed in the face plate 310) of the outlet 120. The
locking
shutter subassembly 320 is configured to permit the plug 100 (see Figures 1,
3, and
4) to enter the plug receiving opening 312, and to prevent other objects (such
as
fingers) from being inserted inside the plug receiving opening 312 of the
outlet 120.
As also mentioned in the Background Section, a conventional RJ-45
type outlet (not shown) includes a carrier or terminal block. In contrast, the
outlet 120 omits the terminal block. Instead of a terminal block, the outlet
120
includes the guide sleeve 370, the wire manager 380, and the housing doors 390
and 392. The housing doors 390 and 392 each pivot with respect to the housing
330
between a closed position and an open position. Turning to Figure 6, when the
housing doors 390 and 392 are both in the closed position, they define an
internal
cavity 396 inside the outlet 120. Turning to Figure 7, when the housing doors
390
and 392 are both in the open position, the wire manager 380 may be inserted
into or
removed from the internal cavity 396.
Referring to Figures 8-10, together the face plate 310, the housing 330,
and the housing doors 390 and 392 house internal components of the outlet 120
(e.g., the locking shutter subassembly 320, the outlet contacts 342, the
optional
16
CA 03002040 2018-04-13
WO 2017/066163
PCT/US2016/056374
spring assembly 350, the contact positioning member 352, the substrate 354,
the
wire contacts 360, the guide sleeve 370, and the wire manager 380).
FACE PLATE
Referring to Figure 11, as mentioned above, the plug receiving opening
312 is formed in the face plate 310. The shape of the plug receiving opening
312
corresponds to the cross-sectional shape of the forward portion 152 (see
Figure 3) of
the plug 100. Thus, the plug receiving opening 312 is configured to permit the
plug 100 to pass therethrough unobstructed. The face plate 310 includes a
conventional lip 314 onto which the latch arm 160 of the plug 100 may latch.
Thus,
the plug 100 may be latched to the outlet 120 when the latch arm 160 engages
the
lip 314 of the face plate 310.
The face plate 310 is configured to be attached to the housing 330. In
the embodiment illustrated, the face plate 310 includes a plurality of hooked
members 316A-316D configured to grab or hook onto corresponding projections
318A-318D (see Figures 18A and 18B), respectively, formed in the housing 330.
When hooked onto the projections 318A-318D, the hooked members 316A-316D
couple (removably or permanently) the face plate 310 to the housing 330.
The face plate 310 includes rearwardly extending projections 319A and
319B positioned above the plug receiving opening 312. In the embodiment
illustrated, the projection 319A is spaced apart from and positioned
underneath the
hooked member 316A. Similarly, the projection 319B is spaced apart from and
positioned underneath the hooked member 316B.
Optionally, the face plate 310 may include an overhanging portion 311
positioned above the plug receiving opening 312. The overhanging portion 311
may
rest upon the housing 330 when the outlet 120 is assembled. A plurality of
dividers
313 may be positioned between the overhanging portion 311 and the plug
receiving
opening 312. When the outlet 120 is assembled, a different one of the dividers
313
may be positioned between adjacent ones of the outlet contacts J1-J8 (see
Figure
20) to help maintain the lateral positioning and/or spacing of the outlet
contacts J1-J8
and their electrical isolation from one another.

The face plate 310 may be constructed from an electrically conductive
and/or dielectric material.
LOCKING SHUTTER SUBASSEMBLY
As mentioned above, the locking shutter subassembly 320 helps
prevent debris and objects other than the plug 100 (see Figures 1, 3, and 4)
from
entering (or being pushed into) the plug receiving opening 312 of the outlet
120.
Turning to Figure 12, the locking shutter subassembly 320 includes a shutter
door 450, a shutter lock member 452, and at least one biasing member (e.g., a
biasing member 454).
Referring to Figure 5, the shutter door 450 is sized and shaped to
cover (or close) the plug receiving opening 312 formed in the face plate 310
to
prevent contaminants and/or objects other than the plug 100 (see Figures 1, 3,
and
4) from being received inside the outlet 120. Returning to Figure 12, the
shutter
door 450 is configured to pivot about a door pivot axis 458 with respect to
the
housing 330 (see Figure 5) between a closed position (see Figures 5, 15A, 15B,
16A, 16B, and 17) and an open position (see Figures 15C and 16C). In the
embodiment illustrated, pivot pins 460A and 460B are formed along a lower
portion
464 of the shutter door 450. The pivot pins 460A and 460B extend along the
door
pivot axis 458. Each of the pivot pins 460A and 460B has a groove 461 that
extends
circumferentially at least partway around the pivot pin. In the embodiment
illustrated,
the pivot pins 460A and 460B extend outwardly from downwardly extending legs
462A and 462B, respectively.
The shutter door 450 has a front facing portion 463 opposite a
rearward facing portion 465. Referring to Figure 13, a first recess 466 is
formed in
the front facing portion 463. Referring to Figure 14, a second recess 467 is
formed
in the rearward facing portion 465. Referring to Figures 13 and 14, a through-
hole or
slot 468 extends at least partway into each of the first and second recesses
466 and
467. The slot 468 is defined between a pair of confronting inside surfaces
457A and
457B. Inwardly extending projections 459A and 459B extend inwardly from the
inside surfaces 457A and 457B, respectively. Referring to Figure 14, the
rearward
facing portion 465 also includes a third recess 470 having an upper inside
18
CA 03002040 2018-04-13
WO 2017/066163
PCT/US2016/056374
surface 472. The third recess 470 intersects or overlaps the second recess
467.
However, the second recess 467 is deeper than the third recess 470.
Referring to Figure 5, the front facing portion 463 (see Figure 13) may
include one or more plug-engaging projections 473A and 473B that extend
forwardly
into the plug receiving opening 312 of the face plate 310. When the plug 100
(or
another object) is inserted into the plug receiving opening 312, the forward
facing
portion 154 (see Figures 3 and 4) of the plug 100 presses against the plug-
engaging
projections 473A and 473B, and the portion 162 (see Figures 3 and 4) of the
latch
arm 160 (see Figures 3 and 4) of the plug 100 presses on the shutter lock
member 452.
Referring to Figure 12, the shutter lock member 452 has a switch
portion 480, an arm portion 482, and an intermediate portion 484. In the
embodiment illustrated, the shutter lock member 452 is a wire segment that has
been bent to define the switch, arm, and intermediate portions 480, 482, and
484.
However, this is not a requirement.
The shutter lock member 452 is rotatable relative to the shutter
door 450 between a locked position (see Figures 5, 15A, 16A, and 17), and an
unlocked position (see Figures 15B, 15C, 16B, and 16C). Referring to Figure
16A, in
the locked position, the switch portion 480 extends forwardly from the front
facing
portion 463 of the shutter door 450, the intermediate portion 484 is
positioned inside
the slot 468 between the inside surfaces 457A and 457B (see Figures 13 and
14),
and, referring to Figure 15A, the arm portion 482 is positioned inside the
second
recess 467. As shown in Figures 15A and 16A, when the shutter door 450 is in
the
closed position, the shutter lock member 452 may be in the locked position.
Further,
as shown in Figures 15B and 16B, when the shutter door 450 is in the closed
position, the shutter lock member 452 may rotated (in a direction indicated by
an
arrow A2) into the unlocked position.
Referring to Figure 16B, when the switch portion 480 is pressed upon
(e.g., by the portion 162 of the latch arm 160 of the plug 100 illustrated in
Figures 3
and 4), the shutter lock member 452 rotates relative to the shutter door 450
until the
switch portion 480 is received (at least partially) inside the first recess
466. At the
same time, referring to Figure 15B, the arm portion 482 at least partially
exits the
19
CA 03002040 2018-04-13
WO 2017/066163
PCT/US2016/056374
second recess 467 thereby positioning the shutter lock member 452 in the
unlocked
position.
Referring to Figure 12, the biasing member 454 applies a biasing force
to the rearward facing portion 465 of the shutter door 450 that biases the
shutter
door 450 toward the closed position (see Figures 5, 15A, 15B, 16A, 16B, and
17). In
the embodiment illustrated, the biasing member 454 includes a pair of spaced
apart
coil springs 490A and 490B connected together by a U-shaped (connecting)
portion 492. The U-shaped portion 492 rotates or pivots relative to the coil
springs
490A and 490B about a pivot axis 493. By way of a non-limiting example, the
biasing member 454 may be constructed from metal wire, plastic, and the like.
Each of the coil springs 490A and 490B has a forwardly extending free
end portion 494. The free end portion 494 of the coil spring 490A is
configured to be
received inside the groove 461 formed in the pivot pin 460A, and the free end
portion
494 of the coil spring 490B is configured to be received inside the groove 461
formed
in the pivot pin 460B.
Referring to Figure 5, the biasing member 454 (see Figure 12) is
positioned behind the shutter door 450 inside the housing 330. Referring to
Figures
15A and 17, when the shutter door 450 is in the closed position and the
shutter lock
member 452 is in the locked position, the coil springs 490A and 490B bias the
U-
shaped portion 492 into the third recess 470 of the shutter door 450 with the
U-
shaped portion 492 positioned adjacent to the upper inside surface 472 of the
third
recess 470. In this configuration, the shutter door 450 is maintained in the
closed
position by the biasing member 454. As may be seen in Figure 16A, the door
pivot
axis 458 is offset with respect to the pivot axis 493 of the U-shaped portion
492 (see
Figure 15A) of the biasing member 454. As a result of this offset, referring
to Figure
17, pressing inwardly (in a direction indicated by an arrow A3) on the front
facing
portion 463 (e.g., on the plug-engaging projections 473A and 473B) of the
shutter
door 450 merely presses the upper inside surface 472 (see Figure 15B) of the
third
recess 470 (see Figure 15B) against the U-shaped portion 492 of the biasing
member 454 but does not translate sufficient force in the direction of
rotation about
the pivot axis 493 (see Figures 12 and 16A) of the U-shaped portion 492 to
allow the
shutter door 450 to be rotated from the closed position to the open position.
Thus,
CA 03002040 2018-04-13
WO 2017/066163
PCT/US2016/056374
the biasing member 454 locks the shutter door 450 in the closed position when
the
shutter lock member 452 is in the locked position.
As shown in Figure 15B, when the shutter lock member 452 is rotated
(in the direction indicated by the arrow A2 illustrated in Figure 16A) from
the locked
position to the unlocked position, the arm portion 482 pushes the U-shaped
portion 492 of the biasing member 454 away from the third recess 470 until the
U-
shaped portion 492 is no longer adjacent the upper inside surface 472 of the
third
recess 470. Thus, pressing inwardly (in the direction indicated by the arrow
A3
illustrated in Figure 17) on the front facing portion 463 (e.g., on the plug-
engaging
projections 473A and 473B) of the shutter door 450 no longer presses the upper
inside surface 472 of the third recess 470 against the U-shaped portion 492 of
the
biasing member 454. Instead, pressing inwardly on the front facing portion 463
of
the shutter door 450 causes the shutter door 450 to pivot about the door pivot
axis
458 (see Figures 12 and 16A) from the closed position to the open position. In
other
words, the shutter lock member 452 allows the shutter door 450 to be pivoted
into
the open position when the shutter lock member 452 is in the unlocked
position.
The shutter door 450 cannot cause the shutter lock member 452 to
transition from the locked to the unlocked position. Instead, an inwardly
directed
force must be applied directly to the switch portion 480 of the shutter lock
member 452 to cause this transition.
Referring to Figure 12, when the shutter door 450 is in the open
position (see Figures 15C and 16C), the U-shaped portion 492 of the biasing
member 454 presses against the shutter lock member 452 and/or the rearward
facing portion 465 of the shutter door 450. Thus, when insufficient force is
applied to
the front facing portion 463 to maintain the shutter door 450 in the open
position, the
biasing member 454 returns the shutter door 450 to the closed position.
Further, if
insufficient force is applied to the switch portion 480 of the shutter lock
member 452,
the U-shaped portion 492 of the biasing member 454 presses against the arm
portion 482 pressing the arm portion 482 into the second recess 467 (see
Figure 14)
and returning the shutter lock member 452 to the unlocked position.
Referring to Figures 4 and 5, when the plug 100 is inserted into the
outlet 120, the portion 162 of the latch arm 160 of the plug 100 first presses
on the
21
CA 03002040 2018-04-13
WO 2017/066163
PCT/US2016/056374
switch portion 480 of the shutter lock member 452 causing the shutter lock
member 452 to rotate from the locked position to the unlocked position. Then,
the
portion 162 and/or the forward facing portion 154 of the plug 100 presses on
the
shutter door 450. If the plug 100 is inserted into the outlet 120 with
sufficient force to
overcome any biasing force exerted by the biasing member 454 (see Figure 12),
the
shutter door 450 pivots from the closed position to the open position. Then,
the
plug 100 is latched inside the outlet 120 by the latch arm 160 to maintain the
shutter
door 450 in the open position. Thus, when the plug 100 is inserted into the
outlet 120, the plug 100 triggers the shutter lock member 452 to remove the U-
shaped portion 492 (see Figure 17) from the third recess 470 (see Figure 17),
and
pushes the shutter door 450 inwardly allowing the plug contacts P1-P8 (see
Figure
3) to engage the outlet contacts J1-J8 (see Figure 20), respectively, and
allows the
latch arm 160 to be latched to the lip 314 (see Figure 11) of the face plate
310.
When the latch arm 160 is unlatched from the lip 314 (see Figure 11) of
the housing 330, and the plug 100 is removed from the outlet 120, the biasing
member 454 (see Figure 17) biases the shutter door 450 toward the closed
position.
Further, referring to Figure 15B, the U-shaped portion 492 of the biasing
member 454 presses the arm portion 482 into the second recess 467 thereby
returning the shutter lock member 452 to the unlocked position. Thus, when the
plug 100 is removed, the shutter door 450 returns to the closed position, and
the
shutter lock member 452 returns to the locked position.
As mentioned above, the locking shutter subassembly 320 is
configured to permit the plug 100 to enter the outlet 120, and to prevent
other objects
(such as fingers) from being inserted inside the outlet 120. The locking
shutter
subassembly 320 remains "locked" against the insertion of other objects (e.g.,
fingertips, fingernails, pencil erasers, other blunt objects, and the like)
into the
outlet 120. Thus, the locking shutter subassembly 320 may be configured to
provide
a factory configurable solution that protects the outlet 120 against
contaminants
(such as dust), and the insertion of objects other than the plug 100.

The frontward opening portion 414 includes recesses 408A and 408B
configured to receive the pivot pins 460A and 460B, respectively, and the coil
springs 490A and 490B, respectively. The projections 318C and 318D partially
overhang the recesses 408A and 408B, respectively. The projection 318C has a
lower surface 405A positioned above the recess 408A, and the projection 318D
has
a lower surface 405B positioned above the recess 408B. Optionally, a stop wall
407A may extend from the inwardly facing surface 403 of the sidewall 400
partway
into the recess 408A, and a stop wall 407B may extend from the inwardly facing
surface 403 of the sidewall 400 partway into the recess 408B.
Inside the recess 408A, the pivot pin 460A is positioned in front of the

may
23
CA 03002040 2018-04-13
WO 2017/066163
PCT/US2016/056374
press upwardly against the lower surface 405B of the projection 318D. The
grooves
461 allow the pivot pin 460B to rotate freely relative to the coil spring
490B.
Opposite sides of the frontward opening portion 414 include recesses
416A and 416B formed in the inwardly facing surface 403 of the sidewall 400,
and
recesses 418A and 418B formed in the exterior surface 404 of the sidewall 400.
The
recesses 416A and 416B are aligned with the recesses 418A and 418B,
respectively. Inwardly extending tabs 419A and 419B are positioned in the
recesses
416A and 416B, respectively.
As may best be viewed in Figure 18B, which provides an enlarged view
of the backside of the housing 330, the sidewall 400 also includes a rearward
opening portion 410 opposite the frontward opening portion 414 (see Figure
18A).
The rearward opening portion 410 is in communication with the interior
receptacle 402.
The substrate 354 is received inside the receptacle 402 through the
rearward opening portion 410 (see Figures 8-10). One or more projections or
stop
walls 420A-420D are formed in the sidewall 400 and extend into the receptacle
402.
The substrate 354 abuts the stop walls 420A-420D inside the receptacle 402.
The
stop walls 420A-420D help maintain the substrate 354 in a desired position
inside
the receptacle 402.
The sidewall 400 includes a plurality of openings 424A-424D, which in
the embodiment illustrated are implemented as through-holes. The openings 424A-
424D are spaced inwardly from the rearward opening portion 410. In the
embodiment illustrated, the rearward opening portion 410 has a generally
rectangular cross-sectional shape and the openings 424A-424D are positioned at
or
near the corners of the rectangular cross-sectional shape.
The sidewall 400 has an upper portion 425 opposite a lower portion
426. An upper door gripping member 427 extends upwardly from the upper portion
425, and a lower door gripping member 428 extends downwardly from the lower

Turning to Figures 8-10, when the housing 330, the substrate 354, the
guide sleeve 370, the wire manager 380, and the housing doors 390 and 392 are
assembled together, the substrate 354 is sandwiched between the stop walls
420A-
420D (see Figure 18B) of the housing 330 and the guide sleeve 370 and held in
place against the stop walls 420A-420D by the guide sleeve 370, the wire
manager
380, and the housing doors 390 and 392.
GROUND SPRINGS
Referring to Figure 1, as mentioned above, the drain wire PDW, the
cable shield 140P, and/or the optional pair shields PPS1-PPS4 of the cable C2
may
be electrically connected to the housing 150 of the plug 100. Referring to
Figure 19,
the ground springs 340A and 340B are each constructed from an electrically
conductive material and electrically connect the housing 330 of the outlet 120
with
the housing 150 (see Figures 1, 3, and 4) of the plug 100. Thus, the drain
wire
PDW, the cable shield 140P, and/or the optional pair shields PPS1-PPS4 are
electrically connected to the housing 330 of the outlet 120 by the ground
springs
340A and 340B.
The ground springs 340A and 340B clip to opposite sides of the
frontward opening portion 414 of the housing 330 and extend into the interior
receptacle 402. Referring to Figures 8-10, when the plug 100 (see Figures 1,
3, and
4) enters the interior receptacle 402 through the plug receiving opening 312
(formed
in the face plate 310), one or both of the ground springs 340A and 340B
contact the
housing 150 of the plug 100 and form an electrical connection therewith.
Referring to Figure 19, the ground springs 340A and 340B may be
substantially identical to one another. In the embodiment illustrated, the
ground
springs 340A and 340B each include an interior portion 436 connected to an
exterior
portion 438 by a bent portion 434. The interior portion 436 includes fingers
430 and
432 that extend inwardly into the interior receptacle 402, and a grip portion
433
configured to be received inside one of the recesses 416A and 416B (see Figure
18A) of the housing 330. The exterior portion 438 is configured to be received
inside
one of the recesses 418A and 418B (see Figure 18A) of the housing 330.
Together,
the grip portion 433 and the exterior portion 438 grip the sidewall 400 of the
housing
CA 03002040 2018-04-13

PCT/US2016/056374
330. In other words, the grip portions 433 of the ground springs 340A and 340B
are
configured to be received inside the recesses 416A and 416B (see Figure 18A),
respectively, and the exterior portions 438 of the ground springs 340A and
340B are
configured to be received inside the recesses 418A and 418B (see Figure 18A),
respectively.
The grip portions 433 of the ground springs 340A and 340B each
include an aperture 435. The aperture 435 of the ground spring 340A is
configured
to receive the tab 419A (see Figure 18A) when the grip portion 433 of the
ground
spring 340A is received inside the recess 416A (see Figure 18A). Similarly,
the
aperture 435 of the ground spring 340B is configured to receive the tab 419B
(see
Figure 18A) when the grip portion 433 of the ground spring 340B is received
inside
the recess 416B (see Figure 18A). Engagement between the apertures 435 of the
ground springs 340A and 340B and the tabs 419A and 419B, respectively, help
maintain the ground springs 340A and 340B, respectively, clipped to the
sidewall 400 in desired positions.
OUTLET CONTACTS
Referring to Figure 20, each of the outlet contacts J1-J8 has a first end
portion 502 configured to be connected to the substrate 354, and a second free
end
portion 504 opposite the first end portion 502. The second free end portions
504 are
arranged in the interior receptacle 402 (see Figures 18A and 18B) of the
housing 330 to contact the plug contacts P1-P8 (see Figure 3), respectively,
of the

SPRING ASSEMBLY
The optional spring assembly 350 helps position the outlet contacts J1-
J8 to contact the plug contacts P1-P8 (see Figure 3), respectively, when the
plug 100 (see Figure 3) is inserted into the outlet 120. While described as
being an
assembly, the spring assembly 350 may be implemented as a single unitary body.
Exemplary suitable structures for implementing the optional spring assembly
350 are
described in U.S. Patent Nos. 6,641,443, 6,786,776, 7,857,667, and 8,425,255.
Further, Leviton Manufacturing Co., Inc. manufactures and sells communication
outlets incorporating Retention Force Technology ("RFT") suitable for
implementing
the spring assembly 350.
The spring assembly 350 biases the outlet contacts J1-J8 against the
contact positioning member 352. In the embodiment illustrated, the spring
assembly 350 is configured to at least partially nest inside the contact
positioning
member 352. However, this is not a requirement. The spring assembly 350 may be
constructed from a dielectric or non-conductive material (e.g., plastic).
The spring assembly 350 may be mounted to the substrate 354 in a
position adjacent the outlet contacts J1-J8. In the embodiment illustrated,
the spring
assembly 350 has a pair of protrusions 520A and 520B configured to be inserted
into
apertures 522A and 522B, respectively, in the substrate 354.
Depending upon the implementation details, the center-most outlet
contacts J3, J4, J5, and J6 may be connected to an optional flexible printed
circuit
board ("PCB") 530 having crosstalk attenuating or cancelling circuits formed
thereon
configured to provide crosstalk compensation. The flexible PCB 530 may include
contacts 533, 534, 535, and 536 configured to be soldered to the centermost
outlet
contacts J3, J4, J5, and J6, respectively.
CONTACT POSITIONING MEMBER
Referring to Figure 20, the contact positioning member 352 may be
mounted to the substrate 354 in a position adjacent the outlet contacts J1-J8
and the
spring assembly 350. In the embodiment illustrated, the contact positioning
member 352 has a pair of protrusions 550A and 550B configured to be inserted
into
apertures 552A and 552B, respectively, in the substrate 354.
27
CA 03002040 2018-04-13
WO 2017/066163
PCT/US2016/056374
In the embodiment illustrated, the contact positioning member 352
includes a front portion 580 with a transverse member 560. The transverse
member
560 includes a plurality of upwardly extending dividers D1-D7 configured to
fit
between adjacent ones of the outlet contacts J1-J8 and help maintain the
lateral
positioning and/or spacing of the outlet contacts J1-J8 and their electrical
isolation
from one another. The spring assembly 350 biases the outlet contacts J1-J8
against
the transverse member 560 of the contact positioning member 352.
In the embodiment illustrated, the contact positioning member 352
includes forwardly opening apertures or recesses 570A and 570B. When the
outlet 120 is assembled, the rearwardly extending projections 319A and 319B
(see
Figure 11) of the face plate 310 are received inside the recesses 570A and
570B,
respectively. The rearwardly extending projections 319A and 319B of the face
plate
310 may help provide support for the front portion 580 of the contact
positioning
member 352.
The contact positioning member 352 is constructed from a dielectric or
non-conductive material (e.g., plastic).
SUBSTRATE
The substrate 354 has a first forwardly facing side 600 opposite a
second rearwardly facing side 602. As mentioned above, the protrusions 520A
and
520B of the spring assembly 350 may be received in the apertures 522A and
522B,
respectively, and the protrusions 550A and 550B of the contact positioning
member 352 may be received in the apertures 552A and 552B, respectively. The
apertures 522A, 522B, 552A, and 552B are formed in the forwardly facing side
600.
The substrate 354 includes circuit paths or traces (not shown) formed
on one or both of the first and second sides 600 and 602 of the substrate 354.
The
traces (not shown) electrically connect the outlet contacts J1-J8,
respectively, to the
wire contacts 361-368, respectively. The substrate 354 includes apertures 611-
618
(e.g., plated through-holes) configured to receive the first end portions 502
of the
outlet contacts J1-J8, respectively, and electrically connect the outlet
contacts J1-J8
to the traces (not shown). The substrate 354 also includes apertures 621-628
(e.g.,
plated through-holes) configured to receive each of the wire contacts 361-368,
28
CA 03002040 2018-04-13
WO 2017/066163
PCT/US2016/056374
respectively, and electrically connect the wire contacts 361-368 to the traces
(not
shown).
In the embodiment illustrated, the first end portions 502 of the outlet
contacts J1-J8 may be pressed into the apertures 611-618, respectively, from
the
first forwardly facing side 600 of the substrate 354 and the wire contacts 361-
368
may be pressed into the apertures 621-628, respectively, in the substrate 354
from
the second rearwardly facing side 602 of the substrate 354. Thus, the outlet
contacts J1-J8 and the wire contacts 361-368 extend away from the substrate
354 in
opposite directions. The outlet contacts J1-J8 may be subsequently soldered
into
place, if desired.
LATCH MEMBER
Referring to Figures 5-10, the latch member 356 may be attached to
the housing 330 or formed as part of the housing 330. Referring to Figure 5,
the
latch member 356 includes one or more connector portions 650 configured to
(removably or permanently) attach the outlet 120 inside an aperture (not
shown)
formed in an external structure (not shown). For example, the connector
portions 650 may be used to attach the outlet 120 inside an aperture (not
shown)
formed in a patch panel, rack, wall outlet, and the like.
WIRE CONTACTS
Referring to Figure 20, as mentioned above, the wire contacts 361-368
are connected to the outlet contacts J1-J8, respectively, by the traces (not
shown)
formed on one or both of the first and second sides 600 and 602 of the
substrate 354. Thus, the wire contacts 361-368 may be characterized as
corresponding to the outlet contacts J1-J8, respectively. Similarly, the wire
contacts 361-368 may be characterized as corresponding to the wires JW1-JW8
(see Figures 1, 26B-26E, and 28A), respectively, of the cable Cl (see Figures
1,
26B-26E, and 28A). Each of the wire contacts 361-368 may be implemented as an
insulation displacement connector ("IDC"). However, this is not a requirement.
In
the embodiment illustrated, the wire contacts 361-368 are positioned on the
29
CA 03002040 2018-04-13
WO 2017/066163
PCT/US2016/056374
substrate 354 in a generally circular or rhombus shaped arrangement. Thus, not
all
of the wire contacts 361-368 are parallel with one another.
The wire contacts 361-368 are configured to cut through the
insulation 144 (see Figure 2) of the wires JW1-JW8 (see Figures 1, 26B-26E,
and
28A), respectively, to form an electrical connection with the conductor 142
(see
Figure 2) of the wires JW1-JW8, respectively. The wire contacts 361-368 may
each
be implemented as a conventional IDC or an IDC 1700 (illustrated in Figures 39
and
40 and described below). As is apparent to those of ordinary skill in the art,
the
outlets described herein (e.g., the outlet 120 and the outlet 1000 illustrated
in Figure
29) are not limited to use with any particular type of IDC or wire contact. As
is
apparent to those of ordinary skill in the art, the wires JW1-JW8 must be
properly
aligned with the IDCs for the IDCs to cut through the insulation 144.
Referring to
Figure 28A, the guide sleeve 370 and the wire manager 380 help position the
wires
JW1-JW8 with respect to the wire contacts 361-368 (see Figure 22),
respectively.
GUIDE SLEEVE
Referring to Figure 22, the guide sleeve 370 is configured to position
the wire manager 380 with respect to the wire contacts 361-368, and determine
the
orientation of the wire manager 380 with respect to the wire contacts 361-368.
Referring to Figures 21A and 21B, the guide sleeve 370 has a body
portion 700 with a forwardly facing surface 702 configured to be positioned
alongside
and spaced apart from the rearwardly facing side 602 (see Figure 22) of the
substrate 354 (see Figure 22). Referring to Figure 21A, recesses or apertures
711-
718 are formed in the forwardly facing surface 702. Referring to Figure 20,
the
recesses 711-718 (see Figure 21A) are configured to receive portions of the
first end
portions 502 of the outlet contacts J1-J8, respectively, that extend
rearwardly beyond
the rearwardly facing side 602 of the substrate 354.
Referring to Figures 21A and 21B, through-channels or through-slots
721-728 extend from the forwardly facing surface 702 through the body portion
700.
Referring to Figure 22, the through-slots 721-728 are configured to receive
the wire
contacts 361-368, respectively, and allow the wire contacts 361-368 to pass
through
the body portion 700 of the guide sleeve 370 and into the wire manager 380.
CA 03002040 2018-04-13
WO 2017/066163
PCT/US2016/056374
Referring to Figure 21B, the guide sleeve 370 includes a plurality of
projections or posts 730A-730D that extend rearwardly from the body portion
700. In
the embodiment illustrated, each of the posts 730A-730D has an inwardly facing
surface 732. A void 736 having a predetermined cross-sectional shape is
defined
between the inwardly facing surfaces 732 of the posts 730A-730D. The
predetermined cross-sectional shape of the void 736 corresponds to the outer
shape
of the wire manager 380. In the embodiment illustrated, the predetermined
cross-
sectional shape of the void 736 is octagonal. Optionally, a projection 738
extends
inwardly into the void 736 from the inwardly facing surface 732 of each of the
posts
730A-730D.
Referring to Figures 21A and 21B, pegs or projections 740A-740D
extent upwardly from the posts 730A-730D, respectively. When the outlet 120 is
assembled, the projections 740A-740D are received inside and engage with the
openings 424A-424D (see Figure 18B), respectively, formed in the housing 330
(see
Figure 18B). For example, the projections 740A-740D may snap inside the
openings
424A-424D, respectively. Engagement between the projections 740A-740D and
openings 424A-424D, respectively, helps maintain the guide sleeve 370 inside
the
housing 330.
Curved or contoured projections 750A-750D spaced apart from the
projections 740A-740D, respectively, also extent upwardly from the posts 730A-
730D, respectively. Together, the contoured projections 750A-750D and the
contoured recesses 429A-429D (see Figure 18B) of the housing 330 (see Figure
18B) each define a circular opening or recess 760 (see Figures 28B and 28C).
Referring to Figure 21B, the guide sleeve 370 may include one or more
alignment blades or key members 770 and 772 that extend rearwardly from the
body
portion 700. Referring to Figure 22, as will be explained below, the key
members
770 and 772 help ensure the wire manager 380 is oriented correctly with
respect to
the wire contacts 361-368 so that the wires JW1-JW8 (see Figures 1, 26B-26E,
and
28A) may be connected to the wire contacts 361-368, respectively. In the
embodiment illustrated, the key member 770 has a generally rectangular cross-
sectional shape that is oriented vertically, and the key member 772 has a
generally
rectangular cross-sectional shape that is oriented horizontally.

The guide sleeve 370 may be constructed from a dielectric or non-
conductive material (e.g., plastic).
WIRE MANAGER
Figure 23A is an exploded perspective view of a front portion of the
wire manager 380, and Figure 23B is an exploded perspective view of a rear
portion
of the wire manager 380. Referring to Figures 23A and 23B, the wire manager
380
includes a housing 800, one or more conductive members 802 and 804, and
optional
labels 806 and 808.
Referring to Figure 22, the housing 800 has an outer shape configured
to be slid into the void 736 defined between the inwardly facing surfaces 732
(see
Figure 21B) of the posts 730A-730D of the guide sleeve 370. Referring to
Figures
23A and 23B, the housing 800 includes a first portion 810 rotatably connected
to a
second portion 812. Both the first and second portions 810 and 812 are
constructed
from a dielectric material. The optional labels 806 and 808 may be adhered
along
outer surfaces of the first and second portions 810 and 812, respectively. The
optional labels 806 and 808 have been omitted from Figures 26E and 28A.
The housing 800 may be selectively transitioned between an open
configuration (see Figures 24B, 25B, 26A, and 26B) and a closed configuration
(see
Figures 24A, 25A, 26C-26E, and 28A) by rotating the first portion 810 relative
to the
second portion 812. Each of the first and second portions 810 and 812 has a
generally C-shaped cross-sectional shape. Thus, when the first and second
portions
810 and 812 are rotated into the closed configuration (see Figures 24A, 25A,
and
26C-26E), an open-ended central passageway 814 is defined between them (see
Figures 7, 24A, 25A, and 26C-26E). In the embodiment illustrated, when in the
closed configuration, the housing 800 has a generally octagonal cross-
sectional
shape and fits within the predetermined cross-sectional shape of the void 736
(see
Figure 22).
Referring to Figure 26C, the central passageway 814 is configured to
receive the cable Cl. As shown in Figure 26B, the cable Cl may be positioned
inside the passageway 814 when the housing 800 is in the open configuration.
Then, as illustrated in Figure 26C, the housing 800 may be transitioned into
the
32
CA 03002040 2018-04-13
WO 2017/066163
PCT/US2016/056374
closed configuration (e.g., by rotating the first portion 810 in a direction
indicated by
arrow A4 (see Figure 26B) with respect to the second portion 812) with the
cable Cl
inside the passageway 814 to compress the cable Cl inside the passageway 814.
Thus, the first and second portions 810 and 812 may be characterized as being
configured to clamp onto an end portion of the cable Cl.
Referring to Figure 23A, the first portion 810 has a first side portion 815
opposite a second side portion 816. Similarly, the second portion 812 has a
first side
portion 817 opposite a second side portion 818. The first side portion 815 of
the first
portion 810 has a first forwardly extending pivot pin 820, and a second
rearwardly
extending pivot pin 822. Referring to Figure 23B, the first side portion 817
of the
second portion 812 has a first channel 830, and a second channel 832. The
first
forwardly extending pivot pin 820 is configured to be received inside the
first channel
830, and the second rearwardly extending pivot pin 822 is configured to be
received
inside the second channel 832. The pivot pins 820 and 822 are selectively
rotatable
inside the channels 830 and 832, respectively. The pivot pins 820 and 822 and
the
channels 830 and 832 may be characterized as forming a hinge that attaches the
first portion 810 to the second portion 812.
Referring to Figure 25B, the second side portion 816 of the first portion
810 has one or more gripping projections 834 and 836. The second side portion
818
of the second portion 812 has a lip or rail 838 configured to be gripped by
the
gripping projections 834 and 836 to maintain the housing 800 in the closed
configuration (see Figures 24A, 25A, 26C-26E, and 28A). In other words, the
gripping projections 834 and 836 and the rail 838 interlock with one another
to
maintain the first and second portions 810 and 812 in the closed
configuration.
Continuing to refer to Figure 25B, the first portion 810 has a forward
portion 840 opposite a rearward portion 842. Similarly, the second portion 812
has a
forward portion 844 opposite a rearward portion 846. The forward portion 840
of the
first portion 810 has an upwardly extending member 850, and the forward
portion
844 of the second portion 812 has a downwardly extending member 852. Referring
to Figure 22, the upwardly extending member 850 includes an upper keyway 854
(see Figure 25B) having a generally rectangular cross-sectional shape that is
oriented vertically and configured to receive the key member 770 of the guide
33
CA 03002040 2018-04-13
WO 2017/066163
PCT/US2016/056374
sleeve 370 but not the key member 772 of the guide sleeve 370. Similarly, the
downwardly extending member 852 includes a lower keyway 856 (see Figure 25B)
having a generally rectangular cross-sectional shape that is oriented
horizontally and
configured to receive the key member 772 of the guide sleeve 370 but not the
key
member 770 of the guide sleeve 370. Thus, when the wire manager 380 is slid
into
the void 736 of the guide sleeve 370, the key member 770 is receivable into
the
upper keyway 854 (but not the lower keyway 856), and the key member 772 is
receivable into the lower keyway 856 (but not the upper keyway 854). In this
manner, the upper and lower keyways 854 and 856 and the key members 770 and
772 determine the orientation of the wire manager 380 with respect to the
guide
sleeve 370.
Referring to Figure 25A, the forward portion 840 of the first portion 810
includes four wire channels or recesses 863, 866, 867, and 868 that extend
outwardly from the passageway 814. As illustrated in Figures 26A and 26D, the
recesses 863, 866, 867, and 868 are configured to receive and grip the wires
JW3,
JW6, JW7, and JW8, respectively, of the cable Cl when the wire manager 380 is
in
the closed configuration. The recesses 863, 866, 867, and 868 provide
passageways for the wires JW3, JW6, JW7, and JW8, respectively, from the
passageway 814.
Referring to Figure 25A, the forward portion 844 of the second portion
812 includes four wire channels or recesses 861, 862, 864, and 865 that extend
outwardly from the passageway 814. As illustrated in Figures 26A and 26D, the
recesses 861, 862, 864, and 865 are configured to receive and grip the wires
JW1,
JW2, JW4, and JW5, respectively, of the cable Cl when the wire manager 380 is
in
the closed configuration. The recesses 861, 862, 864, and 865 provide
passageways for the wires JW1, JW2, JW4, and JW5, respectively, from the
passageway 814.
As shown in Figures 26D, 26E, and 28A, together the recesses 861-
868 (see Figure 25A) may be used to grip the wires JW1-JW8, respectively, and
position them to engage the wire contacts 361-368 (see Figure 22). Referring
to
Figure 25A, in the embodiment illustrated, a gripping projection 870 extends
laterally
into each of the recesses 861-868 to help maintain the wires JW1-JW8,
respectively,

therein. Each of the recesses 861-868 may include side channels 872A and 872B
(see Figure 25B) configured to receive portions of the appropriate one of the
wire
contacts 361-368 (see Figure 22) as the wire contact engages the wire
positioned
inside the recess.
Turning to Figure 24A, a first drain wire channel 880 is formed in the
rearward portion 842 of the first portion 810, and a second drain wire channel
882 is
formed in the rearward portion 846 of the second portion 812. Referring to
Figure
26D, when the cable Cl is inside the passageway 814, the drain wire JDW may
exit
the passageway 814 through one of the drain wire channels 880 and 882 (see
Figure 24A).
Turning to Figure 24A, the rearward portion 842 of the first portion 810
has a rearwardly extending upper cantilever member 886 positioned above a
recess
887, and the rearward portion 846 of the second portion 812 has a rearwardly
extending lower cantilever member 888 positioned under a recess 889. The upper
and lower cantilever members 886 and 888 are configured to deflect into the
recesses 887 and 889, respectively, when inwardly directed lateral forces
(e.g.,
exerted by the housing doors 390 and 392) press upon by the upper and lower
cantilever members 886 and 888.
The upper cantilever member 886 includes one or more upwardly
extending anchor projections 890A-890C, and the lower cantilever member 888
has
one or more downwardly extending anchor projections 892A-892C. In the
embodiment illustrated, the upwardly extending anchor projection 890B is
positioned
between the upwardly extending anchor projections 890A and 890C, and the
downwardly extending anchor projection 892B is positioned between the
downwardly
extending anchor projections 892A and 892C. Further, the anchor projections
890B
and 892B are larger than the anchor projections 890A, 890C, 892A, and 892C.
However, this is not a requirement.
Referring to Figure 25B, the first portion 810 includes a first tab 894
that extends downwardly into the passageway 814, and the second portion 812
includes a second tab 896 that extends upwardly into the passageway 814. The
first
and second tabs 894 and 896 are juxtaposed with one another across the
passageway 814. In the embodiment illustrated, the first tab 894 is positioned
at or
CA 03002040 2018-04-13
WO 2017/066163
PCT/US2016/056374
near the rearward portion 842 of the first portion 810, and the second tab 896
is
positioned at or near the rearward portion 846 of the second portion 812.
Referring to Figure 24A, the conductive members 802 and 804 are
constructed from an electrically conductive material. The conductive members
802
and 804 may be substantially identical to one another and may be characterized
as
being ground springs. The first conductive member 802 extends inside the
passageway 814 along at least a portion of the first portion 810 of the
housing 800,
and the second conductive member 804 extends inside the passageway 814 along
at least a portion of the second portion 812 of the housing 800. Referring to
Figure
26E, the conductive members 802 and 804 (see Figure 26D) are physically and
electrically connected to both the drain wire JDW and the cable shield 140J
(see
Figure 26B) of the cable Cl. If the cable Cl includes the optional pair
shields JPS1-
JPS4 (see Figure 1), they may be physically and electrically connected to the
first
conductive member 802 and/or the second conductive member 804.
Returning to Figure 24A, the first conductive member 802 is configured
to be attached to the rearward portion 842 of the first portion 810 inside the
passageway 814, and the conductive member 804 is configured to be attached to
the rearward portion 846 of the second portion 812 inside the passageway 814.
Referring to Figure 27, each of the conductive members 802 and 804 has a base
portion 900 with a through-hole 902. The through-hole 902 of the first
conductive
member 802 is configured to receive the first tab 894 (see Figure 25B), and
the
through-hole 902 of the second conductive member 804 is configured to receive
the
second tab 896 (see Figure 25B).
A drain wire contact portion 910 extends outwardly from the base
portion 900 of each of the conductive members 802 and 804. The drain wire
contact
portion 910 of the first conductive member 802 is configured to extend at
least
partway into the first drain wire channel 880 (see Figure 24A) so that when
the drain
wire JDW is in the first drain wire channel 880, the drain wire contact
portion 910
contacts and forms an electrical connection with the drain wire JDW.
Similarly, the
drain wire contact portion 910 of the second conductive member 804 is
configured to
extend at least partway into the second drain wire channel 882 (see Figure
24A) so
that when the drain wire JDW is in the second drain wire channel 882, the
drain wire
36
CA 03002040 2018-04-13
WO 2017/066163
PCT/US2016/056374
contact portion 910 contacts and forms an electrical connection with the drain
wire
JDW. Optionally, the drain wire contact portion 910 may include one or more
gripping projections or teeth 914 configured to grip onto the drain wire JDW.
One or more shield engaging portions 920 and 922 extend from the
base portion 900 of each of the conductive members 802 and 804 into the
passageway 814. As illustrated in Figure 26B, an end portion (referred to as a
folded back portion 146J) of the cable shield 140J may be folded back over an
end
portion of the cable jacket 180J. Referring to Figure 27, each of the shield
engaging
portions 920 and 922 is configured to contact and form an electrical
connection with
the folded back portion 146J (see Figure 26B) of the cable shield 140J when
the
cable Cl is positioned inside the passageway 814 (see Figure 26E).
Referring to Figure 26B, if the cable Cl includes the optional pair
shields JPS1-JPS4 (see Figure 1), they may be folded back over the end portion
of
the cable jacket 180J and positioned alongside the folded back portion 146J
(see
Figure 26B) of the cable shield 140J. When folded in this manner, the optional
pair
shields JPS1-JPS4 (see Figure 1) may contact the shield engaging portions 920
and
922 (see Figure 27) of at least one of the conductive members 802 and 804 when
the cable Cl is positioned inside the passageway 814.
Referring to Figure 26E, the shield engaging portions 920 and 922 (see
Figure 27) are configured to apply an inwardly directed biasing force against
the
cable Cl when the cable Cl is inside the passageway 814 to help maintain
contact
with the folded back portion 146J (see Figure 26B) of the cable shield 140J
and the
folded back portions of the optional pair shields JPS1-JPS4, if present.
Referring to Figure 27, by way of a non-limiting example, each of the
shield engaging portions 920 and 922 may be constructed as a cantilever spring
that
includes a free distal portion 921 connected to an anchored proximal portion
924 by
a bent portion 923. The anchored proximal portion 924 is connected to the base
portion 900 at an angle to follow the interior contours of the passageway 814
(see
Figures 24A and 25A). In the embodiment illustrated, the drain wire contact
portion
910 is connected to and extends outwardly from the anchored proximal portion
924
of the shield engaging portion 920.

CA 03002040 2018-04-13
WO 2017/066163
PCT/US2016/056374
The shield engaging portions 920 and 922 each have a door engaging
portion 926 that extends rearwardly and outwardly from the passageway 814 (see
Figures 24A and 25A) and contacts one of the housing doors 390 and 392 (see
Figure 28C). In the embodiment illustrated, the door engaging portion 926 of
each of
the shield engaging portions 920 and 922 is connected to the free distal
portion 921.
As illustrated in Figure 28C, when the housing doors 390 and 392 are closed,
they
may press on one or more of the door engaging portions 926 of the shield
engaging
portions 920 and 922 (see Figure 27) of the conductive members 802 and 804.
The
door engaging portions 926 may be generally hook shaped. Optionally, the drain
wire JDW may be received under and/or wrapped around one or more of the door
engaging portions 926.
As described above, the door engaging portions 926 each contact at
least one of the housing doors 390 and 392 and form an electrical connection
therewith. Thus, the conductive members 802 and 804 electrically connect the
cable
shield 140J and the drain wire JDW with the housing doors 390 and 392, which
are
electrically connected to the housing 330. As described above, if the cable Cl
includes the optional pair shields JPS1-JPS4 (see Figure 1), the conductive
members 802 and 804 may also electrically connect the optional pair shields
JPS1-
JPS4 with the housing doors 390 and 392, which are electrically connected to
the
housing 330.
As mentioned above, referring to Figure 1, the housing 150 of the
plug 100 (which may be connected to the drain wire PDW, the cable shield 140P,
and/or the optional pair shields PPS1-PPS4 of the cable C2) is also
electrically
connected to the housing 330 by the ground springs 340A and 340B (see Figures
8-
10). Thus, a continuous ground may be maintained across the connection 10.
While the guide sleeve 370 has been described as including the key
members 770 and 772 and the wire manager 380 has been described as including
keyways 854 and 856, as is apparent to those of ordinary skill in the art, in
alternate
embodiments, the guide sleeve 370 may include one or more keyways and the wire
manager 380 may include one or more key members. Further, in such
embodiments, one or more of the key members 770 and 772 may be omitted from
38
CA 03002040 2018-04-13
WO 2017/066163
PCT/US2016/056374
the guide sleeve 370, and one or more of the keyways 854 and 856 may be
omitted
from the wire manager 380.
HOUSING DOORS
As mentioned above, each of the housing doors 390 and 392 pivots
with respect to the housing 330. Turning to Figure 28A, when the housing doors
390
and 392 are both in the open position, the wire manager 380 may be inserted
into
the internal cavity 396 (in a direction indicated by an arrow A5). Similarly,
if the wire
manager 380 is already inside the internal cavity 396 (as illustrated in
Figure 4), the
wire manager 380 may be removed therefrom (in a direction opposite the
direction
indicated by the arrow A5) when the housing doors 390 and 392 are both in the
open
position.
As mentioned above, the wire manager 380 positions the wires JW1-
JW8 to contact the wire contacts 361-368, respectively. As the housing doors
390
and 392 are closed, they push the wire manager 380 toward the wire contacts
361-
368 helping to ensure that each of the wire contacts 361-368 successfully cuts
through the insulation 144 (see Figure 2) and contacts the conductor 142 (see
Figure
2) inside the appropriate one of the wires JW1-JW8. In this manner, when the
housing doors 390 and 392 push the wire manager 380 forwardly, the wire
contacts 361-368 cut through the insulation 144 surrounding the conductor 142
of
the wires JW1-JW8, respectively. The wire contacts 361-368 connect the wires
JW1-JW8, respectively, to the traces (not shown) on the substrate 354 (see
Figure
22). As explained above, the traces (not shown) connect the wire contacts 361-
368
to the outlet contacts J1-J8 (see Figure 20).
The housing doors 390 and 392 may be constructed from any material
suitable for constructing the housing 330. The housing doors 390 and 392 may
be
substantially identical to one another or mirror images of one another.
Referring to Figure 8, each of the housing doors 390 and 392 includes
a forward portion 930 opposite a rearward portion 932. Referring to Figures 8
and 9,
the forward portion 930 includes an upper and lower pivot pin 934 and 936.
Referring to Figure 28B, the upper pivot pin 934 (see Figure 9) of the first
housing
door 390 is configured to be received inside the substantially circular recess
760
39
CA 03002040 2018-04-13
WO 2017/066163
PCT/US2016/056374
defined between the contoured projection 750A of the guide sleeve 370 and the
contoured recess 429A of the housing 330. The lower pivot pin 936 of the first
housing door 390 is configured to be received inside the substantially
circular recess
760 defined between the contoured projection 750C (see Figure 21B) of the
guide
sleeve 370 and the contoured recess 429C (see Figure 18B) of the housing 330.
The upper and lower pivot pins 934 and 936 of the first housing door 390 are
configured to be selectively rotated (in directions indicated by double headed
arrow
A6 illustrated in Figure 4) in the recesses 760 to position the first housing
door 390 in
either the open position (see Figure 4, 7, and 28A) or the closed position
(see Figure
1,5, and 6).
Referring to Figure 9, the upper pivot pin 934 of the second housing
door 392 is configured to be received inside the substantially circular recess
760
defined between the contoured projection 750B (see Figure 21A) of the guide
sleeve 370 and the contoured recess 429B (see Figure 18B) of the housing 330.
Referring to Figure 8, the lower pivot pin 936 of the second housing door 392
is
configured to be received inside the substantially circular recess 760 defined
between the contoured projection 750D (see Figure 21B) of the guide sleeve 370
and the contoured recess 429D (see Figure 18B) of the housing 330. The upper
and
lower pivot pins 934 and 936 of the second housing door 392 are configured to
be
selectively rotated (in directions indicated by double headed arrow A7
illustrated in
Figure 4) in the recesses 760 to position the second housing door 392 in
either the
open position (see Figure 4, 7, 28A, and 28B) or the closed position (see
Figure 1, 5,
6, and 28C).
Referring to Figure 28B, when the housing doors 390 and 392 are both
in the open position (see Figure 4, 7, and 28A), the wire manager 380 may be
selectively removed from or placed inside the internal cavity 396. As
mentioned
above, closing the housing doors 390 and 392 with the wire manager 380 inside
the
internal cavity 396 pushes the wire manager 380 forward. When the housing
doors
390 and 392 are both in the closed position (see Figure 1, 5, and 6), the wire
manager 380 is maintained securely inside the internal cavity 396.
Referring to Figure 28A, the forward portions 930 of the housing doors
390 and 392 each include an upper wire manager engaging portion 940 and a
lower
CA 03002040 2018-04-13
WO 2017/066163
PCT/US2016/056374
wire manager engaging portion 942. The upper and lower wire manager engaging
portions 940 and 942 are positioned inwardly from the upper pivot pins 934
(see
Figure 9) and the lower pivot pins 936 (see Figure 8) such that when the
housing
doors 390 and 392 are pivoted from the open position to the closed position,
the
upper and lower wire manager engaging portions 940 and 942 of the housing
doors
390 and 392 are brought into physical contact with the upwardly and downwardly
extending members 850 and 852, respectively, of the wire manager 380 and press
forwardly thereupon. This forwardly directed force presses the wires JW1-JW8
(positioned in the recesses 861-868, respectively) against the wire contacts
361-368,
respectively. Thus, each of the housing doors 390 and 392 may be characterized
as
being a cam, and the upwardly and downwardly extending members 850 and 852
may each be characterized as being a cam follower.
Referring to Figure 7, the rearward portions 932 of the housing doors
390 and 392 each include cutouts or openings 948A and 948B, respectively. The
openings 948A and 948B align to form a throughway into the internal cavity 396
of
the housing 330 (see Figure 6) and the passageway 814 of the wire manger 380
through which the cable Cl (see Figure 4) may pass.
The rearward portions 932 of the first housing door 390 includes an
aperture 950A configured to receive the upwardly extending anchor projection
890A
of the wire manger 380, and an aperture 952A (see Figure 9) configured to
receive
the downwardly extending anchor projection 892A of the wire manger 380.
Similarly,
the rearward portions 932 of the second housing door 392 includes an aperture
950C configured to receive the upwardly extending anchor projection 890C of
the
wire manger 380, and an aperture 952C configured to receive the downwardly
extending anchor projection 892C of the wire manger 380. The rearward portions
932 of the housing doors 390 and 392 include cutouts or openings 960A and
960B,
respectively, that align to form an aperture configured to receive the
upwardly
extending anchor projection 890B of the wire manger 380. Similarly, the
rearward
portions 932 of the housing doors 390 and 392 include cutouts or openings 962A
and 962B, respectively, that align to form an aperture configured to receive
the
downwardly extending anchor projection 892B of the wire manger 380.

PCT/US2016/056374
When the housing doors 390 and 392 are closed, they press
downwardly on the upper cantilever member 886 allowing the upwardly extending
anchor projections 890A and 890C to slide into the apertures 950A and 950C,
respectively, and the upwardly extending anchor projection 890B to slide into
the
aperture formed by the aligned openings 960A and 960B. At the same time, the
housing doors 390 and 392 press upwardly on the lower cantilever member 888
allowing the downwardly extending anchor projections 892A and 892C to slide
into
the apertures 952A and 952C, respectively, and the downwardly extending anchor
projection 892B to slide into the aperture formed by the aligned openings 962A
and
962B. Engagement between the apertures of the housing doors 390 and 392 and
the anchor projections 890A-890C and 892A-892C helps maintain the wire manager
380 in a desired position with respect to the wire contacts 361-368 (see
Figure 20)
and helps maintain the housing doors 390 and 392 in the closed position.
Referring to Figure 28C, as mentioned above, when the housing doors
390 and 392 are closed, they press against the door engaging portions 926 of
the
conductive members 802 and 804 and form electrical connections therewith.
Further, the forward portions 930 of the housing doors 390 and 392 are
received
between the upper and lower door gripping members 427 and 428 (see Figure 18B)
of the housing 330. The upper and lower door gripping members 427 and 428 help
maintain the housing doors 390 and 392 in the closed position.
While the embodiment illustrated includes the housing doors 390 and
392, through application of ordinary skill to the present teachings,
embodiments may
be constructed that include a different number of housing doors (e.g., a
single
housing door).
CABLE TERMINATION
The cable Cl is term ined by the outlet 120 as follows. First, referring
to Figure 26B, the end of the cable Cl being terminated is prepared. This
preparation includes removing an end portion of the cable jacket 180J to
expose the
cable shield 140J, the drain wire JDW, the wires JW1-JW8, and the optional
pairs
shields JPS1-JPS4 (see Figure 1), if present. Next, the cable shield 140J is
folded
back over the cable jacket 180J to define the folded back portion 146J, and
the drain
42
CA 03002040 2018-04-13
WO 2017/066163
PCT/US2016/056374
wire JDW is folded back and positioned adjacent the folded back portion 146J
of the
cable shield 140J.
Second, referring to Figure 26A, the wire manager 380 is obtained.
Referring to Figure 7, if the wire manager 380 is housed inside the internal
cavity
396 of the outlet 120, the housing doors 390 and 392 are opened, and the wire
manager 380 is removed therefrom.
Third, referring to Figure 26B, the housing 800 is placed in the open
configuration and the prepared end of the cable Cl is positioned between the
first
and second portions 810 and 812 inside the open-ended central passageway 814.
Fourth, referring to Figure 26C, the housing 800 is placed in the closed
configuration by rotating the first portion 810 of the housing 800 in the
direction
indicated by the arrow A4 (see Figure 26B) with respect to the second portion
812 of
the housing 800 with the cable Cl inside the passageway 814 thereby
compressing
the cable Cl inside the passageway 814. Further, at least one of the shield
engaging portions 920 and 922 (see Figure 27) of the conductive members 802
and
804 contacts and forms an electrical connection with the folded back portion
146J
(see Figure 26B) of the cable shield 140J.
Fifth, referring to Figure 26D, the wires JW1-JW8 are pressed into the
recesses 861-868, respectively, and optionally trimmed (e.g., using a tool 980
such
as a wire cutter). The gripping projection 870 that extends laterally into
each of the
recesses 861-868 (see Figure 26A) helps maintain the wires JW1-JW8,
respectively,
therein.
Sixth, referring to Figure 26E, the drain wire JDW is pressed into one of
the drain wire channels 880 and 882 (see Figure 24A). By way of a non-limiting
example, in Figure 26D, the drain wire JDW has been pressed into the drain
wire
channel 880. Inside the drain wire channel 880, the drain wire JDW contacts
the
drain wire contact portion 910 of one of the conductive members 802 and 804.
Optionally, the drain wire JDW may be trimmed (e.g., using the tool 980
illustrated in
Figure 26D).
Seventh, referring to Figure 28A, when the housing doors 390 and 392
are both in open positions, and the wire manager 380 is inserted into the
internal
cavity 396 (in the direction indicated by the arrow A5). Figures 4 and 7 each
show
43
CA 03002040 2018-04-13
WO 2017/066163
PCT/US2016/056374
the housing doors 390 and 392 in open positions and the wire manager 380
positioned inside the internal cavity 396. In Figure 7, the cable Cl has been
omitted.
Figure 28B shows the housing door 392 in the open position and the wire
manager 380 positioned inside the internal cavity 396. In Figure 28B, the
housing
door 390 has been removed or exploded.
Finally, the housing doors 390 and 392 are both closed, which presses
the wire manager 380 inwardly to help ensure the wire contacts 361-368 slice
through the outer layers of insulation 144 of the wires JW1-JW8, respectively,
and
form electrical connections with the conductors 142 of the wires JW1-JW8,
respectively. As also explained above, the wire contacts 361-368 are connected
to
the outlet contacts J1-J8, respectively. Further, at least one of the door
engaging
portions 926 of the conductive members 802 and 804 contacts the housing doors
390 and 392 and forms an electrical connection therewith.
In this manner, the outlet 120 enables tooless termination of the cable
Cl.
After the cable Cl has been terminated by the outlet 120, the plug 100
may be inserted into the outlet 120 to form the connection 10 illustrated in
Figure 1.
Inside the connection 10, the plug contacts P1-P8 contact and form electrical
connections with the outlet contacts J1-J8. The plug contacts P1-P8 are
electrically
connected to the wires PW1-PW8, respectively, and the outlet contacts J1-J8
are
electrically connected to the wires JW1-JW8, respectively. Thus, the wires PW1-
PW8 are connected to the wires JW1-JW8, respectively, by the connection 10.
Further, when the plug 100 is inserted into the plug receiving opening
312, the ground springs 340A and 340B (see Figures 8-10) contact the plug
housing
150 and form an electrical connection between the plug housing 150 and the
outlet
housing 330. The outlet housing 330 is connected to the housing doors 390 and
392, which are electrically connected (by the conductive members 802 and 804)
to
the drain wire JDW, the cable shield 140J, and/or the optional pair shields
JPS1-
JPS4, if present. As mentioned above, the housing 150 of the plug 100 may be
connected to the drain wire PDW, the cable shield 140P, and/or the optional
pair
shields PPS1-PPS4, if present, of the cable C2. Thus, a continuous ground may
be
maintained across the connection 10.

RE-TERMINATION
Sometimes, a cable must be re-terminated in the field or a new cable
terminated at the outlet 120. This is accomplished by partially or completely
disconnecting the cable Cl from the outlet 120. Then, terminating the same
cable or
different cable with the outlet 120 using the cable termination process
described
above.
Referring to Figure 28B, the re-termination process begins with
opening the housing doors 390 and 392 and removing the wire manager 380 from
the internal cavity 396 of the outlet 120. Referring to Figure 7, the housing
doors
390 and 392 are opened by pressing inwardly on the anchor projections 890B and
8902B (e.g., with a user's fingers or a tool). Pressing inwardly on the anchor
projections 890B and 8902B applies inwardly directed forces on the upper and
lower
cantilever members 886 and 888, which causes them to deflect inwardly. As the
upper cantilever member 886 deflects inwardly, it pulls the anchor projections
890A
and 890C out of the apertures 950A and 950C, respectively. As the lower
cantilever
member 888 deflects inwardly, it pulls the anchor projections 892A and 892C
out of
the apertures 952A and 952C, respectively.
The housing doors 390 and 392 are pivoted from closed positions to
open positions when (1) the anchor projection 890B is pressed inwardly far
enough
to clear the openings 960A and 960B formed in the rearward portions 932 of the
housing doors 390 and 392, and (2) the anchor projection 892B is pressed
inwardly
far enough to clear the openings 962A and 962B formed in the rearward portions
932 of the housing doors 390 and 392.
Then, when the housing doors 390 and 392 are open, the wire
manager 380 is pulled from the internal cavity 396 of the outlet 120. Next,
referring
to Figures 26C and 26D, the wire manager 380 may be opened and the wires JW1-
JW8 removed from the recesses 861-868, respectively. Further referring to
Figure
26E, the drain wire JDW may be removed from one of the drain wire channels 880
and 882 (see Figure 24A). Alternatively, the wire manager 380 may be replaced
with
a substantially identical wire manager that is not connected to a cable (e.g.,
a new
wire manager or a previously used wire manager that is no longer connected to
a
CA 03002040 2018-04-13
WO 2017/066163
PCT/US2016/056374
cable). At this point, the cable Cl or a different cable may be terminated
with the
outlet 120 using the cable termination process described above.
Referring to Figure 5, the outlet 120 may offer one or more advantages
over prior art RJ-45 type outlets. For example, the locking shutter
subassembly 320
helps prevent the insertion of debris and/or foreign objects (e.g., tools,
fingers, etc.)
into the plug receiving opening 312 (formed in the face plate 310). The outlet
120
enables tooless termination of the cable Cl. The wire manager 380 may provide
substantial contact area between the housing 330 (see Figure 28A-28C) and at
least
one of the cable shield 140J, the drain wire JDW, and the optional pair
shields JPS1-
JPS2 (see Figure 1). The outlet 120 may include snap closures and is easily to
assemble. The outlet 120 provides dedicated termination of the drain wire JDW
to at
least one of the conductive members 802 and 804. The housing doors 390 and 392
(cams) provide mechanical advantage with a small lever arm and allow for a
short
overall outlet length. Engagement of the key member 770 with the upper keyway
854 (see Figure 25B), and the key member 772 with the lower keyway 856 (see
Figure 25B) helps ensure correct alignment of the wire manager 380 and the
wire
contacts 361-368. The outlet 120 includes a conductive housing 330 and
conductive
housing doors 390 and 392 for improved electrical performance.
ALTERNATE EMBODIMENT
Figure 29 is a perspective view of an outlet 1000 that is an alternate
embodiment of the outlet 120 (see Figures 1 and 4-10). Like the outlet 120,
the
outlet 1000 is configured to terminate the communication cable Cl and form a
communication connection (like the connection 10 depicted in Figure 1) with
the plug
100 (see Figures 1, 3, and 4). For ease of illustration, like reference
numerals have
been used in the drawings to identify like components.
The outlet 1000 may be implemented as a Category 8, RJ-45 outlet (or
port). Further, the outlet 1000 may be implemented as a lower category outlet,
such
as a Category 6A outlet, a Category 6 outlet, a Category 5E outlet, and the
like.
Referring to Figure 30, the outlet 1000 includes a face plate 1310, a
shutter subassembly 1320, a housing 1330, one or more ground springs 1340A and
46
CA 03002040 2018-04-13
WO 2017/066163
PCT/US2016/056374
1340B, an optional clip or latch member 1356, a contact subassembly 1358, a
guide
sleeve 1370, a wire manager 1380, and housing doors 1390 and 1392. Together
the
face plate 1310, the housing 1330, and the housing doors 1390 and 1392 house
internal components of the outlet 1000 (e.g., the shutter subassembly 1320,
the
contact subassembly 1358, the guide sleeve 370, and the wire manager 380). The
ground springs 1340A and 1340B clip to the housing 1330 in the same manner
that
the ground springs 340A and 340B (see Figures 8-11 and 19) clip to the housing
330
(see Figure 1, 5-11, 18A-19, and 28A-28C). The latch member 1356 may be
attached to the housing 1330 or formed as part of the housing 1330. The latch
member 1356 is configured to (removably or permanently) attach the outlet 1000
inside an aperture (not shown) formed in an external structure (not shown),
such as
a patch panel, rack, wall outlet, and the like.
The contact subassembly 1358 includes outlet contacts, a contact
positioning member, a substrate, and wire contacts substantially identical to
the
outlet contacts 342, the contact positioning member 352, the substrate 354,
and the
wire contacts 360, respectively, of the contact subassembly 358 (see Figure
20).
Optionally, the contact subassembly 1358 includes a spring assembly
substantially
identical to the optional spring assembly 350.
Referring to Figures 8 and 30, the face plate 1310, the housing 1330,
the ground springs 1340A and 1340B, the latch member 1356, and the contact
subassembly 1358 are substantially identical to the face plate 310, the
housing 330,
the ground springs 340A and 340B, the latch member 356, and the contact
subassembly 358, respectively. Further, these components of the outlet 1000
provide substantially identical functionality to those corresponding
components of the
outlet 120. Therefore, these components of the outlet 1000 have not been
described
in detail below.
SHUTTER SUBASSEMBLY
Referring to Figures 31A-32B, the shutter subassembly 1320 includes
a shutter door 1450 and at least one biasing member (e.g., a biasing member
1454).
Like the locking shutter subassembly 320 (see Figures 5, 8-12, and 15A-17),
the
shutter subassembly 1320 helps prevent debris (e.g., dust and dirt) from
entering the
47
CA 03002040 2018-04-13
WO 2017/066163
PCT/US2016/056374
outlet 1000 (see Figures 29, 30, and 34-36) through a plug receiving opening
1312
(see Figures 29 and 30) substantially identical to the plug receiving opening
312 (see
Figures 5 and 8-11) of the outlet 120 (see Figures 1 and 4-10). However,
unlike the
locking shutter subassembly 320 (see Figures 5, 8-12, and 15A-17) of the
outlet 120,
the shutter subassembly 1320 is not configured to lock and unlock. Instead,
the
shutter door 1450 may be opened by pressing upon it through the plug receiving
opening 1312 (see Figures 29 and 30).
Referring to Figures 29 and 30, the shutter door 1450 is sized and
shaped to cover (or close) the plug receiving opening 1312 formed in the face
plate
1310 to prevent contaminants from being received inside the outlet 1000.
Referring
to Figures 31A and 31B, the shutter door 1450 is configured to pivot about a
door
pivot axis 1458 with respect to the housing 1330 (see Figures 29, 30, and 34-
36)
between a closed position (see Figures 29-32A) and an open position (see
Figure
32B). In the embodiment illustrated, pivot pins 1460A and 1460B are formed
along a
lower portion 1464 of the shutter door 1450. The pivot pins 1460A and 1460B
extend outwardly away from one another along the door pivot axis 1458.
Referring
to Figure 31B, in the embodiment illustrated, the pivot pins 1460A and 1460B
extend
outwardly from downwardly extending legs 1462A and 1462B, respectively.
The shutter door 1450 has a front facing portion 1463 (see Figure 31A)
opposite a rearward facing portion 1465 (see Figure 31B). Referring to Figure
31A,
the front facing portion 1463 (see Figure 13) may include one or more plug-
engaging
projections 1473A and 1473B that extend forwardly into the plug receiving
opening 1312 (see Figures 29 and 30) of the face plate 1310 (see Figures 29
and
30). When the plug 100 (see Figures 1, 3, and 4) is inserted into the plug
receiving
opening 1312, the forward facing portion 154 (see Figures 3 and 4) of the plug
100
presses against the plug-engaging projections 1473A and 1473B.
Referring to Figure 31B, the rearward facing portion 1465 includes first
and second tapered portions 1480A and 1480B. Pins 1482A and 1482B are
positioned on opposite sides of the shutter door 1450. The pins 1482A and
1482B
are spaced apart from the first and second tapered portions 1480A and 1480B,
respectively. The pins 1482A and 1482B are aligned along an axis 1493. The
axis
1493 is offset from and substantially parallel with the pivot axis 1458. In
the
48
CA 03002040 2018-04-13
WO 2017/066163
PCT/US2016/056374
embodiment illustrated, the first and second tapered portions 1480A and 1480B
each
taper rearwardly away from the pins 1482A and 1482B, respectively. Optionally,
the
rearward facing portion 1465 may include a projection or spacer 1484.
Referring to Figures 31B-32B, the biasing member 1454 applies a
biasing force to the rearward facing portion 1465 of the shutter door 1450
that biases
the shutter door 1450 toward the closed position (see Figures 29-32A). By way
of a
non-limiting example, the biasing member 1454 may be constructed from metal
wire,
plastic, and the like.
Referring to Figure 31B, in the embodiment illustrated, the biasing
member 1454 includes a pair of spaced apart coil springs 1490A and 1490B
connected together by a U-shaped (connecting) portion 1492. The coil springs
1490A and 1490B are mounted on the pins 1482A and 1482B, respectively. The
windings of the coil springs 1490A and 1490B may be selectively tightened and
loosed about the axis 1493. Each of the coil springs 1490A and 1490B has a
forwardly extending free end portion 1494. The free end portion 1494 of the
coil
spring 1490A is configured to press against the first tapered portion 1480A,
and the
free end portion 1494 of the coil spring 1490B is configured to press against
the
second tapered portion 1480B. In the embodiment illustrated, the first and
second
tapered portions 1480A and 1480B are each sloped or curved such that the free
end
portions 1494 of the coil springs 1490A and 1490B may slide forwardly along
the first
and second tapered portions 1480A and 1480B, respectively.
Referring to Figures 31A-32B, the biasing member 1454 is positioned
behind the shutter door 1450 inside the housing 1330 (see Figures 29, 30, and
34-
36). Referring to Figure 31B, the coil springs 1490A and 1490B bias the U-
shaped
portion 1492 against the inside of the housing 1330 (see Figures 29, 30, and
34-36).
At the same time, the coil springs 1490A and 1490B bias the free end portions
1494
of the coil springs 1490A and 1490B against the first and second tapered
portions
1480A and 1480B, respectively. Thus, resistance in the coil springs 1490A and
1490B press the free end portions 1494 of the coil springs 1490A and 1490B
against
the shutter door 1450, which pushes or biases the shutter door 1450 forwardly
away
from the U-shaped portion 1492 about the pivot axis 1458. In this manner, the
49
CA 03002040 2018-04-13
WO 2017/066163
PCT/US2016/056374
biasing member 1454 biases the shutter door 1450 toward the closed position
(see
Figures 29-32A), which helps maintain the shutter door 1450 in the closed
position.
The shutter door 1450 may be pivoted about the door pivot axis 1458
from the closed position (see Figures 29-32A) to the open position (see Figure
32B)
by pressing inwardly (in the direction indicated by an arrow A8 illustrated in
Figure
32A) on the front facing portion 1463 (e.g., on the plug-engaging projections
1473A
and 1473B shown in Figure 31A) of the shutter door 1450 with sufficient force
to
overcome the biasing force applied to the rearward facing portion 1465 of the
shutter
door 1450 by the biasing member 1454. As the shutter door 450 opens, the
biasing
member 1454 is compressed. In the embodiment illustrated, as the shutter door
450
opens the coil springs 1490A and 1490B are wound tighter, and the U-shaped
portion 1492 slides rearwardly along the inside of the housing 1330 (see
Figures 29,
30, and 34-36). At the same time, the free end portions 1494 of the coil
springs
1490A and 1490B slide (e.g., downwardly) along the first and second tapered
portions 1480A and 1480B, respectively. Optionally, the spacer 1484 may rest
upon
the inside of the housing 1330 (see Figures 29, 30, and 34-36) when the
shutter
door 1450 is in the open position.
Referring to Figure 32B, when the shutter door 1450 is in the open
position, the U-shaped portion 1492 continues to press against the inside of
the
housing 1330 (see Figures 29, 30, and 34-36) and the free end portions 1494 of
the
coil springs 1490A and 1490B continue to press against the first and second
tapered
portions 1480A and 1480B, respectively. Thus, when insufficient force is
applied to
the front facing portion 1463 to maintain the shutter door 1450 in the open
position,
the biasing member 1454 returns the shutter door 1450 to the closed position.
As
the shutter door 450 closes, the biasing member 1454 is uncompressed. In the
embodiment illustrated, as the shutter door 450 closes, the windings of coil
springs
1490A and 1490B loosen, and the U-shaped portion 1492 slides forwardly along
the
inside of the housing 1330 (see Figures 29, 30, and 34-36). At the same time,
the
free end portions 1494 of the coil springs 1490A and 1490B slide (e.g.,
upwardly)
along the first and second tapered portions 1480A and 1480B, respectively.
Referring to Figure 3, when the plug 100 is inserted into the outlet 1000
(see Figures 29, 30, and 34-36), the portion 162 and/or the forward facing
CA 03002040 2018-04-13
WO 2017/066163
PCT/US2016/056374
portion 154 of the plug 100 presses on the front facing portion 1463 (see
Figures
31A, 32A, and 32B) of the shutter door 1450 (see Figures 29-32B). Referring to
Figure 32B, if the plug 100 (see Figures 1, 3, and 4) is inserted into the
outlet 1000
with sufficient force to overcome the biasing force exerted by the biasing
member 1454 (see Figures 31A-32B) on the rearward facing portion 1465 of the
shutter door 1450, the shutter door 1450 pivots from the closed position (see
Figures
29-32A) to the open position depicted in Figure 32B. Then, the plug 100 may be
latched inside the outlet 1000 (see Figures 29, 30, and 34-36) by the latch
arm 160
(see Figures 3 and 4) to maintain the shutter door 1450 in the open position.
Thus,
when the plug 100 is inserted into the outlet 1000, the plug 100 pushes the
shutter
door 1450 inwardly allowing the plug contacts P1-P8 (see Figure 3) to engage
the
outlet contacts (substantially identical to the outlet contacts 342
illustrated in Figures
8-10 and 20) of the contact subassembly 1358. Further, the latch arm 160 (see
Figures 3 and 4) may be latched to a lip 1314 (see Figure 30) of the face
plate 1310.
The lip 1314 is substantially identical to the lip 314 (see Figure 11). When
the latch
arm 160 is unlatched from the lip 1314 (see Figure 30) of the face plate 1310,
and
the plug 100 is removed from the outlet 1000, the biasing member 1454 (see
Figures
31A-32B) biases the shutter door 1450 toward the closed position. Thus, when
the
plug 100 is removed, the shutter door 450 automatically returns to the closed
position.
As mentioned above, the shutter subassembly 1320 is configured to
permit the plug 100 to enter the outlet 1000, and prevent debris and
contaminants
from entering the outlet 1000. Thus, the shutter subassembly 1320 may be
configured to provide a factory configurable solution that protects the outlet
1000
against contaminants (such as dust).
GUIDE SLEEVE
Referring to Figure 33, the guide sleeve 1370 is substantially similar to
the guide sleeve 370 (see Figures 8-10, 21A-22, and 28A) and provides
substantially
identical functionality thereto. However, in the embodiment illustrated, the
guide
sleeve 1370 includes a single key member 1500 instead of the key member 770
(see
Figure 21B) and the key member 772 (see Figure 21B). The key member 1500 is
51
CA 03002040 2018-04-13
WO 2017/066163
PCT/US2016/056374
positioned inside and extends rearwardly from a first recess 1502A. The guide
sleeve 1370 also includes a second recess 1502B spaced apart from the first
recess
1502A. The first and second recesses 1502A and 1502B may be mirror images of
one another. However, this is not a requirement.
WIRE MANAGER
Referring to Figures 34-36, the wire manager 1380 is substantially
similar to the wire manager 380 (see Figures 7-10, 22-26E, and 28A) and
provides
substantially identical functionality thereto. Therefore, only differences
between the
wire manager 1380 and the wire manager 380 will be described in detail.
One difference between the wire manager 380 (see Figures 7-10, 22-
26E, and 28A) and the wire manager 1380 is that the wire manager 1380 includes
release levers 1510 and 1512 instead of the anchor projections 890B and 892B
(see
Figures 7 and 24A), respectively. The release levers 1510 and 1512 extend
rearwardly and outwardly through the housing doors 1390 and 1392. As will be
described below, the wire manager 1380 is configured to hold or retain the
housing
doors 1390 and 1392 in closed positions (see Figure 34) when the release
levers 1510 and 1512 are in locked positions (see Figures 34). Conversely, the
wire
manager 1380 is configured to release the housing doors 1390 and 1392 so they
can be rotated into open positions (see Figure 36) when the release levers
1510
and 1512 are in unlocked positions (see Figure 35).
In the embodiment illustrated, the release levers 1510 and 1512 remain
in locked positions (see Figure 34) until they are manually transitioned to
unlocked
positions (see Figure 35) by a user. Referring to Figure 34, the release
levers 1510
and 1512 are transitioned to unlocked positions by pressing (or squeezing)
them
toward one another (in directions identified by arrows A9 and Al 0). Referring
to
Figure 35, the release levers 1510 and 1512 are in unlocked positions when the
release levers 1510 and 1512 have been deflected sufficiently toward one
another.
Referring to Figure 37, the wire manager 1380 includes a housing 1520
(see Figures 38A and 38B), one or more conductive members 1522 and 1524, and
optional labels 1526 and 1528. The housing 1520 includes a first portion 1530
rotatably connected to a second portion 1532. Like the first and second
portions 810
52
CA 03002040 2018-04-13
WO 2017/066163
PCT/US2016/056374
and 812 (see Figures 23A-26D), the first and second portions 1530 and 1532 are
selectively rotatable between open and closed configurations. In the open
configuration (not shown), the cable Cl (see Figures 1, 4, 26B-26E, 28A, 29,
38A,
and 38B) may be positioned inside and coupled to the wire manager 1380 in the
same manner the cable Cl may be positioned inside and coupled to the wire
manager 380 (see Figures 7-10, 22-26E, and 28A). Then, at least one of the
first
and second portions 1530 and 1532 may be rotated to place the first and second
portions 1530 and 1532 in the closed configuration to thereby clamp the cable
Cl
inside an open-ended central passageway 1534 (see Figure 36) defined between
the
first and second portions 1530 and 1532. Both the first and second portions
1530
and 1532 are constructed from a dielectric material. The optional labels 1526
and
1528 may be adhered along outer surfaces of the first and second portions 1530
and
1532, respectively.
The first portion 1530 has a forward portion 1540 opposite a rearward
portion 1542. Similarly, the second portion 1532 has a forward portion 1544
opposite a rearward portion 1546. As shown in Figure 38A, the wire manager
1380
has a single keyway 1548 (instead of the upper and lower keyways 854 and 856
depicted in Figure 21B) formed in the forward portion 1540 of the first
portion 1530 of
the housing 1520. The keyway 1548 is configured to receive the key member 1500
(see Figure 33) of the guide sleeve 1370 (see Figures 30 and 33). The keyway
1548
is formed in an upper forwardly projecting portion 1550A. A lower forwardly
projecting portion 1550B is formed in the forward portion 1544 of the second
portion 1532 of the housing 1520. The projecting portions 1550A and 1550B are
configured to be at least partially received by the recesses 1502A and 1502B
(see
Figure 33), respectively, of the guide sleeve 1370.
The wire manager 1380 is properly aligned with the guide sleeve 1370
(see Figures 30 and 33) when the keyway 1548 is positioned to receive the key
member 1500. If the wire manager 1380 is not properly aligned with the guide
sleeve 1370, the wire manager 1380 cannot be fully inserted inside the guide
sleeve 1370 and the housing doors 1390 and 1392 (see Figures 29, 30, and 34-
36)
cannot be closed with the wire manager 1380 inside the housing 1330 (see
Figures
53
CA 03002040 2018-04-13
WO 2017/066163
PCT/US2016/056374
29, 30, and 34-36). Thus, the keyway 1548 and the key member 1500 help ensure
proper orientation of the wire manager 1380 with respect to the guide sleeve
1370.
As shown in Figures 38A and 38B, the wire manager 1380 may be
used to position the wires JW1-JW8 of the cable Cl to engage with the wire
contacts
(substantially identical to the wire contacts 360 illustrated in Figures 8-11
and 20) of
the contact subassembly 1358 (see Figure 30). Referring to Figure 38B, when
the
cable Cl is inside the wire manager 1380, the drain wire JDW may exit
therefrom
through either a drain wire channel 1552 formed in the rearward portion 1542
of the
first portion 1530 or a drain wire channel 1554 (see Figure 37) formed in the
rearward portion 1546 of the second portion 1532 of the housing 1520.
Referring to Figure 37, the rearward portion 1542 of the first
portion 1530 has a rearwardly extending upper cantilever member 1560
positioned
above a recess 1562, and the rearward portion 1546 of the second portion 1532
has
a rearwardly extending lower cantilever member 1564 positioned under a recess
1566. The release levers 1510 and 1512 are mounted on the upper and lower
cantilever members 1560 and 1564, respectively. The upper and lower cantilever
members 1560 and 1564 are configured to deflect into the recesses 1562 and
1566,
respectively, when inwardly directed lateral forces (e.g., exerted on the
release
levers 1510 and 1512 or exerted by the housing doors 1390 and 1392) press upon
by the upper and lower cantilever members 1560 and 1564. Thus, when the
release
levers 1510 and 1512 are pressed upon in the directions identified by the
arrows A9
and A10 (see Figure 34), the upper and lower cantilever members 1560 and 1564
deflect into the recesses 1562 and 1566, respectively.
The upper cantilever member 1560 includes one or more upwardly
extending anchor projections 1570A and 1570B substantially identical to the
anchor
projections 890A and 890C (see Figures 5-7 and 24A), respectively. Similarly,
the
lower cantilever member 1564 includes one or more downwardly extending anchor
projections 1572A and 1572B substantially identical to the anchor projections
892A
and 892C (see Figures 7 and 24A). In the embodiment illustrated, the release
lever
1510 is positioned between the upwardly extending anchor projections 1570A and
1570B, and the release lever 1512 is positioned between the downwardly
extending
anchor projections 1572A and 1572B. When the release lever 1510 is actuated
54
CA 03002040 2018-04-13
WO 2017/066163
PCT/US2016/056374
(e.g., pressed upon in the direction identified by the arrow A9 depicted in
Figure 34),
the upper cantilever member 1560 deflects into the recess 1562, which moves
the
anchor projections 1570A and 1570B inwardly therewith. Similarly, when the
release
lever 1512 is actuated (e.g., pressed upon in the direction identified by the
arrow A10
depicted in Figure 34), the lower cantilever member 1564 deflects into the
recess
1566, which moves the anchor projections 1572A and 1572B inwardly therewith.
Referring to Figure 37, each of the first and second portions 1530 and
1532 includes a pair of tabs 1574 and 1576 that extend inwardly into the
passageway 1534 (see Figures 36 and 38B).
The conductive members 1522 and 1524 are constructed from an
electrically conductive material. The conductive members 1522 and 1524 may be
substantially identical to one another and may be characterized as being
ground
springs. The first conductive member 1522 extends inside the passageway 1534
along at least a portion of the first portion 1530 of the housing 1520, and
the second
conductive member 1524 extends inside the passageway 1534 along at least a
portion of the second portion 1532 of the housing 1520. Referring to Figure
38B, the
conductive members 1522 and 1524 are physically and electrically connected to
both the drain wire JDW and the cable shield 140J (see also Figure 26B) of the
cable
Cl. If the cable Cl includes the optional pair shields JPS1-JPS4 (see Figures
1 and
29), they may be physically and electrically connected to the first conductive
member
1522 and/or the second conductive member 1524.
Referring to Figure 38B, the first conductive member 1522 is
configured to be attached to the first portion 1530 inside the passageway
1534, and
the conductive member 1524 is configured to be attached to the second portion
1532
inside the passageway 1534. Referring to Figure 37, each of the conductive
members 1522 and 1524 has a pair of through-holes 1580 and 1582. The through-
holes 1580 and 1582 of the first conductive member 1522 are configured to
receive
the pair of tabs 1574 and 1576 of the first portion 1530, and the through-
holes 1580
and 1582 of the second conductive member 1524 are configured to receive the
pair
of tabs 1574 and 1576 of the second portion 1532.
Each of the conductive members 1522 and 1524 has a drain wire
contact portion 1586 that is substantially similar to the drain wire contact
portion 910
CA 03002040 2018-04-13
WO 2017/066163
PCT/US2016/056374
(see Figures 26E and 27) of each of the conductive members 802 and 804 (see
Figures 23A-24B, 25B, 26E, and 27). The drain wire contact portion 1586 of the
first
conductive member 1522 is configured to extend at least partway into the first
drain
wire channel 1552 so that when the drain wire JDW (see Figure 38B) is in the
first
drain wire channel 1552, the drain wire contact portion 1586 contacts and
forms an
electrical connection with the drain wire JDW. Similarly, the drain wire
contact
portion 1586 of the second conductive member 1524 is configured to extend at
least
partway into the second drain wire channel 1554 so that when the drain wire
JDW is
in the second drain wire channel 1554, the drain wire contact portion 1586
contacts
and forms an electrical connection with the drain wire JDW. Optionally, the
drain
wire contact portion 1586 may include one or more gripping projections or
teeth 1588
configured to grip onto the drain wire JDW.
Each of the conductive members 1522 and 1524 has one or more
shield engaging portions 1590 and 1592 substantially similar to the shield
engaging
portions 920 and 922 (see Figure 27) of each of the conductive members 802 and
804 (see Figures 23A-24B, 25B, 26E, and 27). The shield engaging portions 1590
and 1592 of the conductive members 1522 and 1524 are configured to contact the
housing doors 1390 and 1392 (see Figures 29, 30, and 34-36), respectively,
when
the housing doors 1390 and 1392 are closed. In this manner, the conductive
members 1522 and 1524 contact the housing doors 1390 and 1392, respectively,
and form electrical connections therewith.
Further, the shield engaging portions 1590 and 1592 of the conductive
members 1522 and 1524 are configured to contact and form an electrical
connection
with the folded back portion 146J (see Figure 26B) of the cable shield 140J
(see
Figures 1, 26B, 26E, 29, and 38B) when the cable Cl is positioned inside the
passageway 1534. Thus, the conductive members 1522 and 1524 electrically
connect the cable shield 140J and the drain wire JDW with the housing doors
1390
and 1392, which are electrically connected to the housing 1330 (see Figures
29, 30,
and 34-36).
Optionally, the shield engaging portions 1590 and 1592 may contact
the optional pair shields JPS1-JPS4 (see Figures 1 and 29) if the pair shields
JPS1-
JPS4 are folded back over the end portion of the cable jacket 180J (see
Figures 1,
56
CA 03002040 2018-04-13
WO 2017/066163
PCT/US2016/056374
26B, 26E, and 38B) and positioned alongside the folded back portion 146J (see
Figure 26B) of the cable shield 140J. In such embodiments, the conductive
members 1522 and 1524 electrically connect the optional pair shields JPS1-JPS4
with the housing doors 1390 and 1392, which are electrically connected to the
housing 1330.
Referring to Figure 3, the housing 150 of the plug 100 (which may be
connected to the drain wire PDW, the cable shield 140P, and/or the optional
pair
shields PPS1-PPS4 of the cable C2) is also electrically connected to the
housing
1330 (see Figures 29, 30, and 34-36) by the ground springs 1340A and 1340B
(see
Figure 30). Thus, a continuous ground may be maintained across the connection
10
when the outlet 1000 is used.
HOUSING DOORS
Referring to Figures 34-36, the housing doors 1390 and 1392 each
pivot independently with respect to the housing 1330. Referring to Figure 36,
when
the housing doors 1390 and 1392 are both in the open position, the wire
manager 1380 may be inserted inside the housing 1330. Similarly, if the wire
manager 1380 is already inside the housing 1330 (as illustrated in Figures 34-
36),
the wire manager 1380 may be removed therefrom when the housing doors 1390
and 1392 are both in the open position.
Referring to Figure 34, the housing doors 1390 and 1392 are
substantially similar to the doors 390 and 392 (see Figures 1, 4-10, 22, and
28A-
28C) of the outlet 120 (see Figures 1, 4-10, and 28A-28C). However, unlike the
housing doors 390 and 392, the housing doors 1390 and 1392 include openings
1600 and 1602 through which the release levers 1510 and 1512, respectively,
may
pass. Referring to Figure 36, a portion of the opening 1600 is formed in each
of the
housing doors 1390 and 1392, and a portion of the opening 1602 is formed in
each
of the housing doors 1390 and 1392. Referring to Figure 34, the openings 1600
and
1602 are configured to allow the release levers 1510 and 1512, respectively,
to
deflect therein. Thus, the release levers 1510 and 1512 may be transitioned
within
the openings 1600 and 1602, respectively, between locked positions (see Figure
34)
and unlocked positions (see Figure 35).

CA 03002040 2018-04-13
WO 2017/066163
PCT/US2016/056374
Referring to Figure 36, the first housing door 1390 includes an aperture
1610A configured to receive the upwardly extending anchor projection 1570A of
the
wire manger 1380, and an aperture 1612A configured to receive the downwardly
extending anchor projection 1572A of the wire manger 1380. Similarly, the
second
housing door 1392 includes an aperture 1610B configured to receive the
upwardly
extending anchor projection 1570B of the wire manger 1380, and an aperture
1612B
configured to receive the downwardly extending anchor projection 1572B of the
wire
manger 1380.
As the housing doors 1390 and 1392 are closed, they press
downwardly on the upper cantilever member 1560 (see Figure 37) allowing the
upwardly extending anchor projections 1570A and 1570B to slide into the
apertures
1610A and 1610B, respectively. At the same time, the housing doors 1390 and
1392 press upwardly on the lower cantilever member 1564 (see Figure 37)
allowing
the downwardly extending anchor projections 1572A and 1572B to slide into the
apertures 1612A and 1612B, respectively. Engagement between the apertures
1610A and 1612A of the housing door 1390 and the anchor projections 1570A and
1572A of the wire manger 1380 helps maintain the housing door 1390 in the
closed
position. Similarly, engagement between the apertures 1610B and 1612B of the
housing door 1392 and the anchor projections 1570B and 1572B of the wire
manger
1380 helps maintain the housing door 1392 in the closed position.
When the release lever 1510 is pressed upon in the direction identified
by the arrow A9 (see Figure 34), the upper cantilever member 1560 deflects
into the
recess 1562, which moves the anchor projections 1570A and 1570B inwardly
therewith. This removes or disengages the upwardly extending anchor
projections
1570A and 1570B from the apertures 1610A and 1610B, respectively. Similarly,
when the release lever 1512 is pressed upon in the direction identified by the
arrow
A10 (see Figure 34), the lower cantilever member 1564 deflects into the recess
1566, which moves the anchor projections 1572A and 1572B inwardly therewith.
This removes or disengages the downwardly extending anchor projections 1572A
and 1572B from the apertures 1612A and 1612B, respectively. When the upwardly
extending anchor projections 1570A and 1570B are disengaged from the apertures
1610A and 1610B, respectively, and the downwardly extending anchor projections
58
CA 03002040 2018-04-13

PCT/US2016/056374
1572A and 1572B are disengaged from the apertures 1612A and 1612B,
respectively, the housing doors 1390 and 1392 may be rotated to open positions
(see Figure 36).
With the housing doors 1390 and 1392 rotated to open positions (see
Figure 36), the wire manager 1380 may be removed from inside the housing 1330
(see Figures 29, 30, and 34-36). Then, the wire manager 1380 may be opened,
and
the cable Cl (see Figure 29) removed therefrom. Next, the cable Cl (see Figure
29)
may be re-terminated at the outlet 1000 or a new cable terminated at the
outlet 1000.
INSULATION DISPLACEMENT CONNECTORS
As mentioned above, the wire contacts 360 (see Figures 8-11 and 20)
may each be implemented as an insulation displacement connector ("IDC").
Figures
39 and 40 depict an IDC 1700 that may be used to implement each of the wire
contacts 360. The IDC 1700 may be characterized as being a low profile IDC
that
has a reduced overall size compared to a conventional IDC and requires a
relatively
lower termination force. As illustrated in Figures 39 and 40, the IDC 1700 may
be
substantially planar.
Referring to Figures 39 and 40, the IDC 1700 is generally Y-shaped
having a generally T-shaped base portion 1710 from which two spaced apart
substantially parallel beams 1712 and 1714 extend. The base portion 1710 is
configured to be pressed into an opening (e.g., one of the apertures 621-628
illustrated in Figure 20) formed in a substrate (e.g., the substrate 354
illustrated in
Figures 8-11, 20, and 22). The beams 1712 and 1714 are configured to extend
away from the substrate in the same direction.
A wire receiving gap 1720 is defined between the beams 1712 and
1714. The beams 1712 and 1714 each have a free distal end portion 1730
opposite
the base portion 1710. The free distal end portions 1730 taper outwardly and
away
from the wire receiving gap 1720. These tapers help the wire slide along the
free
distal end portions 1730 of the beams 1712 and 1714 and further into the wire
receiving gap 1720.
The beams 1712 and 1714 each have an inner edge portion 1732 that
extends along the wire receiving gap 1720. The inner edge portions 1732 are
each
59
CA 03002040 2018-04-13
WO 2017/066163
PCT/US2016/056374
beveled or relieved from the free distal end portion 1730 at least part way
along the
wire receiving gap 1720 to define a recessed or relieved portion 1734 and a
cutting
edge 1736. The cutting edges 1736 may be formed by performing a coining
operation on the IDC 1700 and/or mechanically removing a portion of the inner
edge
portions 1732.
When one of the wires JW1-JW8 (see Figures 1, 26B-26E, and 28A) is
inserted into the wire receiving gap 1720, the cutting edges 1736 slice
through the
outer layer of insulation 144 (see Figure 2) and provide a gas tight fit with
the
electrical conductor 142 (see Figure 2) without gouging out a significant
portion of
the electrical conductor 142 in the process. As is apparent to those of
ordinary skill
in the art, one of the wires JW1-JW8 (see Figures 1, 26B-26E, and 28A) is
inserted
into the wire receiving gap 1720 such that the outer layer of insulation 144
(see
Figure 2) is sliced along a lateral direction that is not parallel with (e.g.,
is orthogonal
to) the longitudinal direction of the wire. This positions the beams 1712 and
1714 on
opposite sides of the wire. After the outer layer of insulation 144 (see
Figure 2) has
been cut through, the beams 1712 and 1714 physically contact the electrical
conductor 142 (see Figure 2) and exert a lateral force thereupon that helps
maintain
the wire therebetween and inside the wire receiving gap 1720. The beams 1712
and
1714 also form an electrical connection with the electrical conductor 142 (see
Figure
2) and conduct any signal transmitted thereby to one or more conductors on the
substrate (e.g., the substrate 354 illustrated in Figures 8-11, 20, and 22).
Because the beams 1712 and 1714 are thinner along their cutting
edges 1736, the beams 1712 and 1714 require less insertion force to cut
through the
outer layer of insulation 144 (see Figure 2) than would be required by the
beams
1712 and 1714 if they did not include the relieved portion 1734 and the
cutting edge
1736. For example, when all eight wires JW1-JW8 (see Figures 1, 26B-26E, 28A,
and 41) are pressed into eight IDCs like the IDC 1700, the insertion force
required
may be reduced to about 30 pounds. By comparison, about 40 pounds of pressure
is required to press the eight wires JW1-JW8 into IDCs that do not include the
relieved portions 1734 and the cutting edges 1736. Because less insertion
force is
required, the IDC 1700 is able to maintain more IDC-to-wire contact pressure
per
CA 03002040 2018-04-13
WO 2017/066163
PCT/US2016/056374
unit area while slicing through the outer layer of insulation 144 (see Figure
2) during
an initial termination and subsequent repeat terminations.
The IDC 1700 may have a reduced overall size, meaning the IDC 1700
may have a "low profile" compared to a standard or conventional IDC. For
example,
the IDC 1700 may have a height of only about 0.322 inches, a width of only
about
0.120 inches, and a thickness of only about 0.016 inches. Because of its
reduced
size and smaller reflected image compared to standard sized IDC, the IDC 1700
may
have less near end crosstalk ("NEXT") and/or Return Loss.
By way of a non-limiting example, the IDC 1700 may be constructed
using C51000 phosphor bronze and plated with nickel and/or tin.
ALTERNATE EMBODIMENT
Figure 41 is a perspective view of an outlet 2000 that is an alternate
embodiment of the outlet 1000 (see Figures 29, 30, and 34-36). Like the outlet
1000, the outlet 2000 is configured to terminate the communication cable Cl
and
form a communication connection (like the connection 10 depicted in Figure 1)
with
the plug 100 (see Figures 1, 3, and 4). Referring to Figure 42A, the outlet
2000
includes the wire manager 1380, which may be coupled to the cable Cl (see
Figure
41) in the same manner described above with respect to the outlet 1000 (see
Figures 29, 30, and 34-36). The outlet 2000 may be implemented as a Category
8,
RJ-45 outlet (or port). Further, the outlet 2000 may be implemented as a lower
category outlet, such as a Category 6A outlet, a Category 6 outlet, a Category
5E
outlet, and the like.
Referring to Figure 42A, the outlet 2000 is substantially identical to the
outlet 1000 (see Figures 29, 30, and 34-36) except the housing doors 1390 and
1392 of the outlet 2000 each includes one or more bumps or projections 2011,
2012,
2013 (see Figures 43A, 44, and 45), and 2014 (see Figures 43A, 44, and 45). In
the
embodiment illustrated, the projections 2011-2014 have each been implemented
as
a spherical cap (e.g., a hemisphere) having a curved side that faces
outwardly.
However, this is not a requirement. Referring to Figure 44, in the embodiment
illustrated, the projections 2011-2014 are formed in forward portions 2930 of
the
housing doors 1390 and 1392.

Referring to Figures 42B and 43B, the housing 1330 includes
contoured recesses 2429A-2429D (substantially identical to the contoured
recesses
429A-429D illustrated Figure 18B) and the guide sleeve 1370 includes contoured
projections 2750A-2750D (substantially identical to the contoured projections
750A-
750D illustrated Figures 21A and 21B). Together, the contoured projections
2750A-
2750D and the contoured recesses 2429A-2429D each define a substantially
circular
opening or recess 2760 (substantially identical to the recesses 760 depicted
in
Figures 28B and 28C).
Referring to Figure 44, each of the housing doors 1390 and 1392 has
an inner surface 2500 opposite an outer surface 2502. The inner surface 2500
of
the forward portion 2930 includes upper and lower pivot pins 2934 and 2936
(substantially identical to the pivot pins 934 (see Figure 9) and 936 (see
Figures 8,
10, and 22), respectively. Referring to Figures 42B and 43B, the upper and
lower
pivot pins 2934 and 2936 (see Figure 44) are each configured to be received
inside
one of the recesses 2760.
Referring to Figure 44, the forward portions 2930 of the housing doors
1390 and 1392 each include upper and lower wire manager engaging portions 2940
and 2942 that are substantially identical to the upper and lower wire manager
engaging portions 940 and 942, respectively, illustrated in Figures 10, 28A,
and 28B.
In the embodiment illustrated in Figure 44, the projection 2011 is formed on
the outer
surface 2502 of the forward portion 2930 of an upper portion 2504 of the
housing
door 1390 between a central portion of the pivot pin 2934 (formed on the inner
surface 2500) and the upper wire manager engaging portion 2940. The projection
2013 is formed on the outer surface 2502 of the forward portion 2930 of a
lower
portion 2505 of the housing door 1390 between a central portion of the pivot
pin
2936 (formed on the inner surface 2500) and the lower wire manager engaging
portion 2942. The projection 2012 is formed on the outer surface 2502 of the
forward portion 2930 of an upper portion 2508 of the housing door 1392 between
a
central portion of the pivot pin 2934 (formed on the inner surface 2500) and
the
upper wire manager engaging portion 2940. The projection 2014 is formed on the
outer surface 2502 of the forward portion 2930 of a lower portion 2509 of the
housing
door 1392 between a central portion of the pivot pin 2936 (formed on the inner

surface 2500) and the lower wire manager engaging portion 2942. In the
embodiment illustrated, the projections 2011 and 2012 overlap with the pivot
pins
2934 of the housing doors 1390 and 1392, respectively, and the projections
2013
and 2014 overlap with the pivot pins 2936 of the housing doors 1390 and 1392,
respectively. However, this is not a requirement.
Referring to Figure 42A, rearward portions 2932 of the housing doors
1390 and 1392 each include cutouts or openings 2948A and 2948B, respectively.
The openings 2948A and 2948B are substantially identical to the openings 948A
and
948B (see Figures 6, 7, and 28B). The openings 2948A and 2948B align and
together form a throughway 2506 (see Figures 41, 44, and 45) into the housing
1330
through which the cable Cl (see Figure 41) may pass when the cable Cl is
coupled
to the wire manger 1380 and the wire manger 1380 is positioned at least
partially
inside an internal cavity 2396 of the outlet 2000. Referring to Figure 45, the
passageway 1534 of the wire manger 1380 is aligned with the throughway 2506 to
allow the cable Cl (see Figure 41) to pass therethrough and into the
passageway 1534.
Referring to Figure 43A, like in the outlet 1000 (see Figures 29, 30, and
34-36), engagement between the apertures 1610A (see Figure 42A) and 1612A of
the housing door 1390 and the anchor projections 1570A and 1572A (see Figure
42A), respectively, of the wire manger 1380 helps maintain the housing door
1390 in
the closed position. Similarly, referring to Figure 42A, engagement between
the
apertures 1610B and 1612B of the housing door 1392 and the anchor projections
1570B and 1572B, respectively, of the wire manger 1380 helps maintain the
housing
door 1392 in the closed position. Referring to Figure 43A, when the release
lever 1510 is pressed upon in the direction identified by the arrow A9 (see
Figure
34), the upper cantilever member 1560 deflects into the recess 1562, which
moves
the anchor projections 1570A and 1570B inwardly therewith. This removes or
disengages the upwardly extending anchor projections 1570A and 1570B from the
apertures 1610A (see Figure 42A) and 1610B, respectively. Similarly, referring
to
Figure 42A, when the release lever 1512 is pressed upon in the direction
identified
by the arrow Al 0 (see Figure 34), the lower cantilever member 1564 deflects
into the
recess 1566, which moves the anchor projections 1572A and 1572B inwardly
63

therewith. This removes or disengages the downwardly extending anchor
projections 1572A and 1572B from the apertures 1612A (see Figure 43A) and
1612B, respectively. When the upwardly extending anchor projections 1570A (see
Figure 43A) and 1570B are disengaged from the apertures 1610A and 1610B,
respectively, and the downwardly extending anchor projections 1572A and 1572B
are disengaged from the apertures 1612A (see Figure 43A) and 1612B,
respectively,
the housing doors 1390 and 1392 may be rotated to into the open positions
(illustrated in Figures 42A and 43A).
Referring to Figure 42A, like in the outlet 1000 (see Figures 29, 30, and
34-36), the housing 1330 of the outlet 2000 includes an upper door gripping
portion
or member 2427 that extends upwardly from an upper portion 2425 of the housing
1330. Referring to Figure 45, the upper door gripping member 2427 has an
inwardly
facing portion or surface 2430 that extends over at least a portion of the
forward
portions 2930 (see Figure 44) of the upper portions 2504 and 2508 of the
housing
doors 1390 and 1392 when the housing doors 1390 and 1392 are in the closed
positions. The projections 2011 and 2012 of the housing doors 1390 and 1392,
respectively, extend outwardly beyond the inwardly facing surface 2430 when
the
housing doors 1390 and 1392 are in the open positions (see Figures 42A and
43A).
Thus, when the housing doors 1390 and 1392 are in the open positions, the
projections 2011 and 2012 may abut a free end portion 2436 (see Figure 42B) of
the
upper door gripping member 2427 and help prevent the housing doors 1390 and
1392, respectively, from closing. In this manner, the projections 2011 and
2012 help
prevent the housing doors 1390 and 1392 from closing (e.g., when the outlet
2000 is
positioned with the housing doors 1390 and 1392 facing downwardly) so that a
user
may insert the wire manager 1380 (see Figures 42A-43B and 45) without also
having
to hold the housing doors 1390 and 1392 in the open positions. To close the
housing doors 1390 and 1392, sufficient rotational force must be applied to
the
housing doors 1390 and 1392 to force the projections 2011 and 2012,
respectfully,
under the upper door gripping member 2427. In this manner, the projections
2011
and 2012 of the housing doors 1390 and 1392, respectively, may be positioned
to
engage the inwardly facing surface 2430 of the upper door gripping member
2427.

PCT/US2016/056374
Referring to Figure 43A, like in the outlet 1000 (see Figures 29, 30, and
34-36), the housing 1330 includes a lower door gripping portion or member 2428
that
extends downwardly from a lower portion 2426 of the housing 1330. Referring to
Figure 45, the lower door gripping member 2428 has an inwardly facing portion
or
surface 2432 that extends over at least a portion of the forward portions 2930
(see
Figure 44) of the lower portions 2505 and 2509 of the housing doors 1390 and
1392
when the housing doors 1390 and 1392 are in the closed positions. The
projections
2013 and 2014 of the housing doors 1390 and 1392, respectively, extend
outwardly
beyond the inwardly facing surface 2432 when the housing doors 1390 and 1392
are
in the open positions (see Figures 42A and 43A). Thus, when the housing doors
1390 and 1392 are in the open positions, the projections 2013 and 2014 may
abut a
free end portion 2438 (see Figure 43B) of the lower door gripping member 2428
and
help prevent the housing doors 1390 and 1392, respectively, from closing. In
this
manner, the projections 2013 and 2014 help prevent the housing doors 1390 and
1392 from closing (e.g., when the outlet 2000 is positioned with the housing
doors
1390 and 1392 facing downwardly) so that a user may insert the wire manager
1380
(see Figures 42A-43B and 45) without also having to hold the housing doors
1390
and 1392 in the open positions. To close the housing doors 1390 and 1392,
sufficient rotational force must be applied to the housing doors 1390 and 1392
to
force the projections 2013 and 2014, respectfully, above the lower door
gripping
member 2428. In this manner, the projections 2013 and 2014 of the housing
doors
1390 and 1392, respectively, may be positioned to engage the inwardly facing
surface 2432 of the lower door gripping member 2428.
Referring to Figure 45, when the housing door 1390 is in the open
position (see Figures 42A and 43A), together, the projections 2011 and 2013
may
abut the free end portions 2436 (see Figure 42B) and 2438 (see Figure 43B),
respectively, of the upper and lower door gripping members 2427 and 2428,
respectively, to help prevent the housing door 1390 from closing. Similarly,
when the
housing door 1392 is in the open position (see Figures 42A and 43A), the
projections
2012 and 2014 may abut the free end portions 2436 (see Figure 42B) and 2438
(see
Figure 43B), respectively, of the upper and lower door gripping members 2427
and
2428, respectively, to help prevent the housing door 1392, respectively, from
closing.
CA 03002040 2018-04-13
WO 2017/066163
PCT/US2016/056374
Thus, the projections 2011-2014 help prevent the housing doors 1390 and 1392
from
closing (e.g., when the outlet 2000 is positioned with the housing doors 1390
and
1392 facing downwardly) so that the user may insert the wire manager 1380
without
also having to hold the housing doors 1390 and 1392 in the open positions.
Referring to Figure 45, when the housing doors 1390 and 1392 are
rotated from the open positions to the closed positions, the forward portions
2930
(see Figures 42A, 43A, and 44) of the upper portions 2504 and 2508 of the
housing
doors 1390 and 1392 are received under the upper door gripping member 2427 of
the housing 1330 (see Figures 41-43B). Similarly, the forward portions 2930
(see
Figures 42A, 43A, and 44) of the lower portions 2505 and 2509 of the housing
doors
1390 and 1392 are received above the lower door gripping member 2428 of the
housing 1330 (see Figures 41-43B). Thus, the forward portions 2930 (see
Figures
42A, 43A, and 44) of the housing doors 1390 and 1392 are sandwiched between
the
upper and lower door gripping members 2427 and 2428 of the housing 1330. When
so received, the projections 2011 and 2012 bear against the inwardly facing
surface
2430 of the upper door gripping member 2427 and the projections 2013 and 2014
bear against the inwardly facing surface 2432 of the lower door gripping
member
2428 and may help maintain the housing doors 1390 and 1392 in the closed
position. Thus, when the cable Cl (see Figure 41) is terminated by the outlet
2000
(see Figures 41, 42A, 43A, and 45), the projections 2011 and 2012 are
compressed
elastically by the upper door gripping member 2427 and the projections 2013
and
2014 are compressed elastically by the lower door gripping member 2428. As
described below, this compression and/or friction between the projections 2011
and
2012 and the upper door gripping member 2427 and friction between the
projections
2013 and 2014 and the lower door gripping member 2428 improves electrical
performance of the outlet 2000 (and may help prevent the housing doors 1390
and
1392 from opening).
As explained above, the cable Cl has at least one grounding
component (e.g., the drain wire JDW illustrated in Figure 38B and the cable
shield
140J illustrated in Figures 1, 26B, 26E, 29, and 38B). Referring to Figure
42B, the
drain wire contact portion 1586 of the conductive member 1522 of the wire
manager
1380 contacts and forms an electrical connection with the drain wire JDW (see
66
CA 03002040 2018-04-13
WO 2017/066163
PCT/US2016/056374
Figure 38B) of the cable Cl (see Figure 41) when the drain wire JDW is in the
first
drain wire channel 1552. Similarly, the drain wire contact portion 1586 of the
conductive member 1524 of the wire manager 1380 contacts and forms an
electrical
connection with the drain wire JDW (see Figure 38B) when the drain wire JDW is
in
the second drain wire channel 1554. Referring to Figure 43B, one or both of
the
shield engaging portions 1590 and 1592 (of one or both of the conductive
members
1522 and 1524) contact the housing doors 1390 and 1392 (see Figures 41, 42A,
43A, 44, and 45), respectively, when the housing doors 1390 and 1392 are
closed.
In this manner, at least one of the conductive members 1522 and 1524 contacts
the
housing doors 1390 and 1392, respectively, and forms an electrical connection
therewith. Further, at least one of the shield engaging portions 1590 and 1592
of the
conductive members 1522 and 1524 contacts and forms an electrical connection
with the folded back portion 146J (see Figure 26B) of the cable shield 140J
(see
Figures 1, 26B, 26E, 29, and 38B) when the cable Cl (see Figure 41) is
positioned
inside the passageway 1534 (see Figure 45). Thus, one or both of the
conductive
members 1522 and 1524 electrically connect both the cable shield 140J and the
drain wire JDW with one or both of the housing doors 1390 and 1392.
As also mentioned above, referring to Figure 42A, the housing 1330
and the housing doors 1390 and 1392 are each constructed from an electrically
conductive material, such as metal. The housing doors 1390 and 1392 are
connected to the housing 1330, which is connected to the ground springs 1340A
and
1340B. The ground springs 1340A and 1340B are connected to the plug 100 (see
Figures 1, 3, and 4), which is connected to the cable C2 (see Figures 1, 3,
and 4).
Thus, a ground path extends from the cable Cl to the outlet 1000 (or the
outlet 2000
illustrated in Figures 41-43B and 45). The ground path also extends from the
outlet
1000 (or the outlet 2000) to the plug 100 (and on to the cable C2).
In the outlet 1000 (see Figures 29, 30, and 34-36), along the ground
path, an electrical connection between the housing door 1390 and the housing
1330
is formed between the upper and lower pivot pins 2934 and 2936 of the housing
door
1390 and the contoured recesses 2429A and 2429C. Thus, the effectiveness of
this
connection depends upon how well the upper and lower pivot pins 2934 and 2936
fit
within the recesses 2760 and contact the contoured recesses 2429A and 2429C of
67
CA 03002040 2018-04-13
WO 2017/066163
PCT/US2016/056374
the housing 1330. Similarly, an electrical connection between the housing door
1392
and the housing 1330 is formed between the upper and lower pivot pins 2934 and
2936 of the housing door 1392 and the contoured recesses 2429B and 2429D.
Thus, the effectiveness of this connection depends upon how well the upper and
lower pivot pins 2934 and 2936 fit within the recesses 2760 and contact the
contoured recesses 2429B and 2429D of the housing 1330.
In contrast, referring to Figure 45, in the outlet 2000, electrical
connections are formed along the ground path between the housing door 1390 and
the housing 1330 (see Figures 41-43B) by the projections 2011 and 2013 and the
upper and lower door gripping members 2427 and 2428, respectively. Similarly,
electrical connections are formed along the ground path between the housing
door
1392 and the housing 1330 (see Figures 41-43B) by the projections 2012 and
2014
and the upper and lower door gripping members 2427 and 2428, respectively.
Thus,
referring to Figure 41, the projections 2011, 2012, 2013 (see Figures 43A, 44,
and
45), and 2014 (see Figures 43A, 44, and 45) help ground performance of the
outlet
2000 particularly when the cable Cl is undergoing stresses and/or strain by
forming
a reliable connection between the housing 1330 and at least one of the housing
doors 1390 and 1392. In essence, the projections 2011-2014 help stabilize the
connection between the cable Cl and the outlet 2000 and may help reduce minor
fluctuations in the ground performance when the cable Cl is moved. Thus, the
projections 2011-2014 improve the electrical performance of the outlet 2000.
Further, the projections 2011-2014 may help hold the cable Cl in place
and prevent the cable Cl from moving. For example, the projections 2011-2014
may help prevent a portion of the cable positioned within the throughway 2506
from
moving with respect to the housing 1330 and/or the housing doors 1390 and
1392.
The projections 2011-2014 may be characterized as providing a mechanical
detent
feature. Referring to Figure 42A, the mechanical detent feature may help keep
the
wire manager 1380 in place (e.g., when the outlet 2000 is oriented with the
housing
doors 1390 and 1392 facing downwardly). This feature may also help reduce or
eliminate the influence of gravity on the housing doors 1390 and 1392 when the
wire
manager 1380 is positioned inside the outlet 2000 with the cable Cl (see
Figure 41)
coupled thereto.
68
CA 03002040 2018-04-13
WO 2017/066163
PCT/US2016/056374
Referring to Figures 42A and 43A, as mentioned above, the housing
doors 1390 and 1392 may be selectively rotated into open positions. Before or
after
the housing doors 1390 and 1392 are opened, the cable Cl (see Figure 41) may
be
coupled to the wire manager 1380, which may be positioned inside the outlet
2000 in
the same manner in which the wire manager 1380 is positioned inside the outlet
1000 (see Figures 29, 30, and 34-36). Then, the housing doors 1390 and 1392
may
be rotated into closed positions (see Figures 41 and 45) to thereby push the
wire
manager 1380 into position. Closing the housing doors 1390 and 1392 also
positions the projections 2011 and 2012 to bear against (and form an
electrical
connection with) the upper door gripping member 2427 and positions the
projections
2013 and 2014 to bear against (and form an electrical connection with) the
lower
door gripping member 2428.
Referring to Figures 42A and 43A, when the housing doors 1390 and
1392 are in open positions, the wire manager 1380 may be removed from inside
the
housing 1330. Then, the wire manager 1380 may be opened, and the cable Cl (see
Figure 41) removed therefrom. Next, the cable Cl (see Figure 41) may be re-
term mated at the outlet 2000 or a new cable terminated at the outlet 2000.
Referring to Figure 45, while in the embodiment illustrated, the
projections 2011 and 2013 have been described as being positioned on the
housing
door 1390 and the projections 2012 and 2014 have been described as being
positioned on the housing door 1392, in alternate embodiments, the projections
2011-2014 may be positioned on other structures of the outlet 2000. For
example,
the projections 2011 and 2012 may be positioned on the inwardly facing surface
2430 of the upper door gripping member 2427 and configured to grip the upper
portions 2504 and 2508 of the housing doors 1390 and 1392. Similarly, the
projections 2013 and 2014 may be positioned on the inwardly facing surface
2432 of
lower door gripping member 2428 and configured to grip the lower portions 2505
and
2509 of the housing doors 1390 and 1392. By way of another non-limiting
example,
the projection 2011 may be positioned on the housing door 1390 and the
projection
2012 may be positioned on the inwardly facing surface 2430 of the upper door
gripping member 2427. Similarly, the projection 2013 and/or the projection
2014
may be positioned on the inwardly facing surface 2432 of the lower door
gripping
69
CA 03002040 2018-04-13
WO 2017/066163
PCT/US2016/056374
member 2428. In such embodiments, whichever of the projection 2013 and the
projection 2014 that is/are not positioned on the lower door gripping member
2428
may be positioned on the housing door 1390 or the housing door 1392. Further,
while the housing door 1390 has been illustrated as including a single
projection on
its upper and lower portions 2504 and 2505 (e.g., the projections 2011 and
2013,
respectively) and the housing door 1392 has been illustrated as including a
single
projection on its upper and lower portions 2508 and 2509 (e.g., the
projections 2012
and 2014, respectively), this is not a requirement. In alternate embodiments,
the
housing doors 1390 and 1392 may include more than one projection at each of
these
locations. Further, in some embodiments, one of the upper and lower portions
2504
and 2505 of the housing door 1390 may not include a projection. Similarly, one
of
the upper and lower portions 2508 and 2509 of the housing door 1392 may not
include a projection.
The foregoing described embodiments depict different components
contained within, or connected with, different other components. It is to be
understood that such depicted architectures are merely exemplary, and that in
fact
many other architectures can be implemented which achieve the same
functionality.
In a conceptual sense, any arrangement of components to achieve the same
functionality is effectively "associated" such that the desired functionality
is achieved.
Hence, any two components herein combined to achieve a particular
functionality
can be seen as "associated with" each other such that the desired
functionality is
achieved, irrespective of architectures or intermedial components. Likewise,
any two
components so associated can also be viewed as being "operably connected," or
"operably coupled," to each other to achieve the desired functionality.
While particular embodiments of the present invention have been
shown and described, it will be obvious to those skilled in the art that,
based upon
the teachings herein, changes and modifications may be made without departing
from this invention and its broader aspects and, therefore, the appended
claims are
to encompass within their scope all such changes and modifications as are
within the
true spirit and scope of this invention. Furthermore, it is to be understood
that the
invention is solely defined by the appended claims. It will be understood by
those
CA 03002040 2018-04-13
WO 2017/066163
PCT/US2016/056374
within the art that, in general, terms used herein, and especially in the
appended
claims (e.g., bodies of the appended claims) are generally intended as "open"
terms
(e.g., the term "including" should be interpreted as "including but not
limited to," the
term "having" should be interpreted as "having at least," the term "includes"
should
be interpreted as "includes but is not limited to," etc.). It will be further
understood by
those within the art that if a specific number of an introduced claim
recitation is
intended, such an intent will be explicitly recited in the claim, and in the
absence of
such recitation no such intent is present. For example, as an aid to
understanding,
the following appended claims may contain usage of the introductory phrases
"at
least one" and "one or more" to introduce claim recitations. However, the use
of
such phrases should not be construed to imply that the introduction of a claim
recitation by the indefinite articles "a" or "an" limits any particular claim
containing
such introduced claim recitation to inventions containing only one such
recitation,
even when the same claim includes the introductory phrases "one or more" or
"at
least one" and indefinite articles such as "a" or "an" (e.g., "a" and/or "an"
should
typically be interpreted to mean at least one" or one or more"); the same
holds true
for the use of definite articles used to introduce claim recitations. In
addition, even if
a specific number of an introduced claim recitation is explicitly recited,
those skilled
in the art will recognize that such recitation should typically be interpreted
to mean at
least the recited number (e.g., the bare recitation of "two recitations,"
without other
modifiers, typically means at least two recitations, or two or more
recitations).
Accordingly, the invention is not limited except as by the appended
claims.
