SMALL FORM-FACTOR PLUGGABLE MODULE
BACKGROUND
Technical Field
[0001] The disclosure relates to a small form-factor pluggable module and
particularly relates
to a small form-factor pluggable module that helps dissipate heat of an
internal component.
Description of Related Art
[0002] When a conventional small form-factor pluggable module is operating,
the electronic
devices inside the module may generate high heat. In order to prevent heat
from accumulating
inside and result in dysfunction of the operation when the whole module is
operating, the
conventional small form-factor pluggable module dissipates the high heat by
guiding heat to a
metal surface of the overall module through a thermal pad or a heat sink
additionally installed
inside. However, since the conventional small form-factor pluggable module
only relies on the
thermal pad or the heat sink to dissipate heat, the heat dissipation
efficiency may be not favorable,
which leads to accumulated heat inside the conventional small form-factor
pluggable module and
results in dysfunction of the operation of the whole module.
SUMMARY
[0003] The disclosure provides a small form-factor pluggable module capable of
alleviating heat
accumulation inside the whole module of a conventional small form-factor
pluggable module due
to unfavorable heat dissipation efficiency that results in operation
dysfunction of the whole module.
[0004] A small form-factor pluggable module according to an embodiment of the
disclosure
includes a case. The case is provided with a front plate, a top plate
connected with the front plate,
a bottom plate connected with the front plate and opposite to the top plate
and two side plates
connected with the front plate and opposite to each other. The top plate and
the bottom plate are
-1-
CA 3070971 2020-02-04
respectively connected between the two side plates. The front plate is
provided with at least one
first opening. The first opening is suitable for being penetrated by at least
one connector. A
cross-sectional area of the first opening is larger than a cross-sectional
area of the connector at
where the connector penetrates the first opening.
[0005] In one embodiment of the disclosure, the cross-sectional area of the
first opening is larger
than a multiple of the cross-sectional area of the at least one connector at
the first opening, the
multiple being the number of the at least one connector.
[0006] In one embodiment of the disclosure, the first opening is connected
with at least two
diagonal corners of the front plate.
[0007] In one embodiment of the disclosure, the first opening is an inclined
opening.
[0008] In one embodiment of the disclosure, the first opening is an L-shaped
opening.
[0009] In one embodiment of the disclosure, the first opening is H-shaped.
[0010] In one embodiment of the disclosure, the first opening is provided with
at least one
penetration part and at least one ventilation part connected with the
penetration part, and the
penetration part is suitable for being penetrated by the connector.
[0011] In one embodiment of the disclosure, the front plate further includes a
second opening.
[0012] In one embodiment of the disclosure, the first opening and the second
opening are
parallel to each other.
[0013] In one embodiment of the disclosure, the first opening and the second
opening are each
suitable for being penetrated by the at least one connector.
[0014] Based on the above, in the small form-factor pluggable module according
to the
disclosure, an internal space can communicate with the outside to add a heat
convection passage.
Accordingly, the heat inside the small form-factor pluggable module can be
discharged to facilitate
the heat dissipation efficiency and ensure that the operation function of the
small form-factor
pluggable module is stable and normal.

DESCRIPTION OF THE EMBODIMENTS
[0024] FIG. lA is a three-dimensional schematic view of a small form-factor
pluggable module
-3-
CA 3070971 2020-02-04
according to a first embodiment of the disclosure. FIG. 1B is a front
schematic view of the small
form-factor pluggable module in FIG. 1A with a part of components being
omitted. FIG. 1C is
a view illustrating a relationship between cross-sectional areas of a first
opening of the small form-
factor pluggable module and a connector penetrating the first opening
according to a first
embodiment of the disclosure. Referring to FIG. 1A, FIG. 1B and FIG. 1C, the
small form-factor
pluggable module 100 according to the present embodiment includes a case 110.
The case 110
is provided with a front plate 111, a top plate 112, a bottom plate 113 and
two side plates (for
example, but not limited to a first side plate 114 and a second side plate
115). All the top plate
112, the bottom plate 113, the first side plate 114 and the second side plate
115 are connected to
the front plate 111. The top plate 112 and the bottom plate 113 are opposite,
and the first side
plate 114 and the second side plate 114 are opposite. The top plate 112 and
the bottom plate 113
are connected between the first side plate 114 and the second side plate 115.
In other words, the
top plate 112 is located at one side of the first side plate 114 and the
second side plate 115, while
the bottom plate 113 is located at the other side of the first side plate 114
and the second side plate
115.
[0025] The front plate 111 is provided with at least one first opening 111a,
and the first opening
111a is suitable for being penetrated by at least one connector (for example,
but not limited to a
first connector 50a and a second connector 50b). As shown in FIG. 1C, a cross-
sectional area
Al of the first opening 111a is larger than a cross-sectional area A2 of the
connector (for example,
but not limited to the first connector 50a or the second connector 50b) at
where the connector
penetrates the first opening 111a. Therefore, in the small form-factor
pluggable module 100
according to the disclosure, the internal space can communicate with the
outside to add a heat
convection passage. Accordingly, the heat inside the small form-factor
pluggable module 100
can be discharged to facilitate the heat dissipation efficiency and ensure
that the operation function
of the small form-factor pluggable module 100 is stable and normal, and
furthermore, the
-4-
CA 3070971 2020-02-04
operation dysfunction of the whole module resulting from heat accumulation
inside the whole
module due to poor heat dissipation of a conventional small form-factor
pluggable module is
alleviated.
[0026] It should be noted that the at least one mentioned by the disclosure
refers to no limitation
to a number, and the number may be one or more. In addition, the one named as
first or second
in nouns is for the sake of clear distinction, not intended to limit the
number.
[0027] Referring to FIG. 1A, FIG. 1B and FIG. 1C, the first opening 111a is
provided with at
least one penetration part (for example, but not limited to a first
penetration part 111a1 and a
second penetration part 111a2) and at least one ventilation part (for example,
but not limited to a
ventilation part 111a3). The ventilation part 111a3 is connected between the
first penetration
part 111a1 and the second penetration part 111a2. The at least one penetration
part is suitable
for being penetrated by at least one connector, for example, the first
connector 50a penetrates the
first penetration part 1111a and the second connector 50b penetrates the
second penetration part
111a2, but the disclosure is not limited thereto. In other words, the first
penetration part 111a1
may allow the first connector 50a to penetrate, and the second penetration
part 111a2 may allow
the second connector 50b to penetrate, while the ventilation part 111a3 is
configured as a heat
dissipation path for communicating the inside of the small form-factor
pluggable module 100 with
the outside at any time, so that the effect of discharging the heat inside the
small form-factor
pluggable module 100 can be achieved.
[0028] It should be noted that the first penetration part 111a1 and the second
penetration part
111a2 may have the same or different cross-sectional shapes, and the first
penetration part 111a1
and the second penetration part 111a2 may have the same or different cross-
sectional sizes, so as
to allow the first connector 50a and the connector 50b having corresponding
cross-sectional shapes
and sizes to penetrate. The cross-sectional shapes and sizes of the first
connector 50a and the
second connector 50b are not limited as long as the ventilation part 111a3 is
provided as the heat
-5-
CA 3070971 2020-02-04
dissipation path for communicating the inside of the small form-factor
pluggable module 100 with
the outside.
[0029] For example, when the first penetration part 111a1 and the second
penetration part 111a2
have the same cross-sectional shape and size, the first opening 111a has the
cross-sectional area
Al, the first connector 50a has the cross-sectional area A2 at where the
connector 50a penetrates
the first penetration part 111a, and the cross-sectional area Al of the first
opening 111a is larger
than, for example, but is not limited to, two times of the cross-sectional
area A2 of of the first
connector 50a (or the second connector 50b) at the first opening 111a, i.e.,
Al>2A2 (the cross-
sectional area Al is larger than the cross-sectional areas A2 of N connectors
at where the N
connectors penetrate the first opening 111a, i.e., Al>NA2). In this way,
referring to FIG. 1A
and FIG. 1C, when the first connector 50a penetrates the first penetration
part 111a1 and the
second connector 50b penetrates the second penetration part 111a2, it is
ensured that a remaining
space may form the ventilation part 111a3, so that the inside of the small
form-factor pluggable
module 100 can communicate with the outside.
[0030] In other embodiments not shown, if only one connector is provided,
accordingly, only
one penetration part is required, and in this case, it only requires that the
cross-sectional area of
the first opening is larger than the cross-sectional area the single connector
at where the connector
penetrates the first opening and the ventilation part is reserved.
[0031] The principle of improving the heat dissipation effect of the small
form-factor pluggable
module according to the disclosure has been described as above. Various
feasible configurations
for improving the heat dissipation effect of the small form-factor pluggable
module will be
described as below. It should be noted that various examples disclosed below
are merely for
illustration, and not intended to limit how the configuration of the
disclosure is set.
[0032] Referring to FIG. 1A and FIG. 1B, in the small form-factor pluggable
module 100

are connected at a corner Cl, the first side plate 114 and the bottom plate
113 are connected at a
corner C2, the bottom plate 113 and the second side plate 115 are connected at
a corner C3, and
the second side plate 115 and the top plate 112 are connected at a corner C4.
The first penetration
part 111a1 is located on a position, adjacent to the corner Cl, of the front
plate 111, and the second
penetration part 111a2 is located on a position, adjacent to the corner C3, of
the front plate 111.
In other words, the first opening 111a is connected with at least two diagonal
corners of the front
plate 111 (for example, but not limited to two diagonal corners, adjacent to
the corner Cl and the
corner C3, of the front plate 111), so that the first opening 111a is an
inclined opening, and there
is no limit to which two diagonal corners the first opening 111a is connected
with. In addition,
both the first penetration part 111a1 and the second penetration part 111a2
have the same cross-
sectional shapes and sizes and are substantially in noncircular shapes having
unfilled corners at
the left and right sides. Moreover, the cross section of the ventilation part
111a3 is square
substantially.

cross sections of
a first penetration part 211A1, a second penetration part 211A2, a first
penetration part 211B1 and

factor pluggable module 200A according to the second embodiment, the cross
section of a
ventilation part 211A3 is square substantially.
[0035] In the small form-factor pluggable module 200B according to the third
embodiment, the
cross section of a ventilation part 211B3 is substantially round.
[0036] In the small form-factor pluggable module 200C according to the fourth

the first opening 200C is an opening obliquely formed in the front plate and
is connected with two
diagonal corners of the front plate, although a first penetration part, a

above, the first opening
211C is suitable for being penetrated by at least one connector, and has a
cross-sectional area
larger than a cross-sectional area of the connector at where the connector
penetrates the first
opening 211C, so that the first opening 211C has a heat dissipation path for
communicating the
inside with the outside to increase the heat dissipation efficiency.
[0037] FIG. 3A and FIG. 3B are front schematic views of small form-factor
pluggable modules

3A and FIG. 3B,
the similarity of a small form-factor pluggable module 300A according to the

and a small form-factor pluggable module 300B according to the sixth
embodiment lies in that,
the cross sections of both a first opening 311A and a first opening 311B are
substantially L-shaped.
[0038] The difference of the fifth and sixth embodiments lies in that, in the
small form-factor
pluggable module 300A according to the fifth embodiment, the first opening
311A is provided
with a first penetration part 311A 1 and a second penetration part 311A2 which

penetration part 311A2,
so that the first opening 311A can provide the ventilation part 311A3 with a
larger cross-sectional
area, and furthermore, the heat dissipation effect of the small form-factor
pluggable module 300A
is further improved.

first opening 311B.
[0040] FIG. 4A and FIG. 4B are front schematic views of small form-factor
pluggable modules
according to seventh and eighth embodiments of the disclosure. Referring to
FIG. 4A and FIG.
4B, the similarity of a small form-factor pluggable module 400A according to
the seventh
embodiment and a small form-factor pluggable module 400B according to the
eighth embodiment
lies in that, cross sections of a first opening 411A and a first opening 411B
are substantially H-
shaped. The difference of the small form-factor pluggable module 400A
according to the seventh
embodiment and the small form-factor pluggable module 400B according to the
eighth
embodiment lies in that, setting directions of the H-shaped cross sections of
the first opening 411A
and the first opening 411B are different. A first penetration part, a second
penetration part and a
ventilation part are not clearly defined as mentioned above in the small form-
factor pluggable
module 400A according to the seventh embodiment and the small form-factor
pluggable module
400B according to the eighth embodiment. Actually, based on the number of
connectors and a part
that penetrates the first opening 411A and the first opening 411B, a part
without being penetrated
by connectors of the first opening 411A and the first opening 411B is the
ventilation part for
communicating the inside of the small form-factor pluggable module 400A and
the small form-
factor pluggable module 400B with the outside.
[0041] FIG. 5A and FIG. 5B are front schematic views of small form-factor
pluggable modules
according to ninth and tenth embodiments of the disclosure. Referring to FIG.
5A and FIG. 5B,

ninth embodiment
and a small form-factor pluggable module 500B according to the tenth

opening 511B2 respectively. A first opening 511A1 and a second opening 511A2
are parallel to
each other, and the first opening 511B1 and the second opening 511B2 are
parallel to each other.
The first opening Al,511 the second opening 511A2, the first opening
511B1 and the second
opening 511B2 are each suitable for being penetrated by at least one
connector. In other words,
each opening may be provided with a ventilation part for heat dissipation.
[0042] The difference of the small form-factor pluggable module 500A according
to the ninth
embodiment and the small form-factor pluggable module 500B according to the
tenth embodiment
lies in that the first opening 511A 1 and the second opening 511A2 are
arranged in a horizontal
direction, while the first opening 511B1 and the second opening 511B2 are
arranged in a vertical
direction.
[0043] In other embodiments not shown, the first opening and the second
opening may be
obliquely arranged on the front plate.
[0044] Therefore, the ventilation part for communicating the inside of the
small form-factor
pluggable module with the outside may be correspondingly reserved according to
an actual
.. demand for penetrating the connector.
[0045] Based on the above, in the small form-factor pluggable module according
to the
disclosure, an internal space can communicate with the outside to add a heat
convection passage.
Accordingly, the heat inside the small form-factor pluggable module can be
discharged to facilitate
the heat dissipation efficiency and ensure that the operation function of the
small form-factor
pluggable module is stable and normal, and furthermore, heat accumulation
inside the whole
module of the conventional small form-factor pluggable module due to
unfavorable heat
dissipation efficiency that results in operation dysfunction of the whole
module is alleviated.
[0046] It will be apparent to those skilled in the art that various
modifications and variations can
be made to the structure of the disclosed embodiments without departing from
the scope or spirit
of the disclosure. In view of the foregoing, it is intended that the
disclosure cover modifications
