~'hi~ ~n~-en+uion rela-tes to a proces~ and ~pparatus where~
b~ a pl~ralit~ o~ wires may be handled simul-taneou~ly ~or
their termination, ~or example to a multi;pin connec+or.
One of the principal problem~ a~sociated with the lab
rication of any wiring system o~ substantial complex-lt~ is the
necessity ~or the termination of individual T.rire~ to co~nec~ors
and other similar electrical componentsO ~aturally, when cach
wire must be indi~idually soldered to the a.pp~opriate ter~lnal
p~n, the labor cost associatea ~Tith ~he fabrication or ~vhe
electrical ~stem becomes of major importance. ~urthe~, the
indi~idual soldering operations can o~ten resull i~ mi~ake~
and defective terminations simply becau~e o~ the number of in~
di~idual operations in~ol~red. ~he proper placement o~ e~ch wire
~elative to the appropriate pin, the ex~ct location o. the ~older
bead and the preYention of electrical paths bet~een adjace~t ~iires
and pins ar~ important requirema~ts ~or each ~ire termination. I'
is ~urther advantageous to ~ave terminal sleeves asæocia~ed ~ith
each terminal connection ~or strength, insula~ion9 protection
ana ~i~ormity o~ the connection. All of these conditions pre-
ferably sho~d be met ~or each termina~ created~ ~hus~ each ~ire
~erm-'.nation must be accurately and yet rapidl~ perlormed i~l order
that a competitive and reliable system may ~e created~
~he present invention assists in accurate and simultaneous
prep2ration o~ a plurality of wires and provides for more e~act
positio~in~ o~ each individual wire with its proper terminal pinO
~urth~r, the system provides, if reguired, for the use o~ individ~
ual '~e~minal sleeYes abo~ each wire termination~ This proceduYe
~or the termination o~ ~ pluralit~ of wires ~rith a multi~pln
con~ector or other elec~r~cal compo~ent help~ r~duce the labor
~03ts, asse~bly time, possibility o~ errors during asse~bly, and
possibility o~ de~ective terminationsO ~urther, terminal sleeves
may be employed without causin~ ~rayin~ and buckling o-~ the wire
ends during the ~ositioning o~ the wires within the sleeves.
More speci~ically, the process and apparatu~ o~ the in~en~
tion allow the po~itionin~ o~ a pluralit~ o~ ter~i~al ~leeves ~or
the receipt o~ individual wires be~ore these wires are cut to
the appropria~e length and ~tripped~ Once the wi~es are posit:io~
ed within the sleeves~ they may be sirnultaneousl~ or indi~idually
cut and stripped i~ preparation for ~ermination with a m~ti~
pl~ connector. When the te~minal ends o~ the indi~idual wires
have been preparedS the wires and ~leeves ma~ be transported to~
~5 gether to a positio~ adjacent ~o the mul-ti~pin con~ector~ The
sIeeves mag then be wiped over the terminal ends o~ the wires
and moved onto the connector pins in a single mot10n. In this
wiping process, the ~ilaments o~ eac;l str~pped wire are dra~m
~ogether withi~ the sleeve and held with the appropria~e pi~.
~he slee~es ma~ be heat shrinkable and each contain a solder
beaa. Such terminal slee~es are disclosed in the ~.ietmore
~ited States ~etters Patent ~o. 3~243~211. ~hus, soldered
and insulated terminations may be createdO
To accomplish this ~imult~neous handling o~ a large ~umber o~
~5 wires, a block hereinafter re~erred to as an "identification bloc~'~
i~ pro~ided i~ which each wire is positioned so that it is ready
~or ali~nment with a desired pin o~ a multi pin connector -Irhen

the wires ~re positioned9 the~ ~ay be cut to length~ stripped of
a l~ngth o~ insul~tion ~nd po~itioned adjacent the appropriate
connector pins or other connector device~. ~n entire set of
wires can be simultaneously subjected to these step~ becau~e o~
the prior po~itioning of the wires in the identifioation blockO
~urther, t~e identificatlon block can be u~ed ~imultaneou~l~ to
~ipe the pl~ality o~ ter~linal ~lee~es al~ng the wi~a to the cut
an~ stripped end~ ~hereo~ and over the connector pin~ o~ the
multi-pin connector. ~ wire clamp is also inclucled to work
conjunc~ion ~Jith ~he identificatio~ block to re~ist lon~ituclina~
mo~ement of th~ wires through the identi*ication block in one
direction and to p~omote relati~e longitudinal moYement of the
~ires through the identi~i~atio~ block i~ ~he other di~e~tionO
~ccoraingly, the pre~ent inventio~ pro~ides a method ~or the
