15 Dctailed De3cr~p_0n Referring to FIG. 1, a connector as~embly ;n accorda~ce with the present invention include~ an outlet box 100 having openings (not ~ho~n) through whic~ a pair of cable~ 200 and 200' having ~ultiple in3ulated condustor~ 210 extend. The condqctor~ 210 of the cable~ 200 and 200' are re~pestively 20 electrically terminatet by connector~ 300 a~d 300' comprising an index ~trip 320 and a connecting bloek 340 of the type di~clMed in U. S. Patent 3,798,587.
A~ ~how~ m~t clearly i~ FIG. 2, t~e indcx ~trip 320 include~ a base portion 322 fro~a ~hich a ~ultiple of ~paced pairs ot oppo~ed parallel extendingteeth 324 exte~d. The forward e~d~ of the tee~h 324 are beveled to provide V.
25 ~haped entr~ces into slo~ 325 formed be~ween adjwent pairs of teetb. Each 910t 3~ recei~e~ ~ inti~ridual in~ulated co~ductor 210, a~d as 3een from FIG. 1,the i~ula~e~ duetor~ 210 aro thereby or~anized in a 3paced linear arra~8o~o~t. E~ch 3ide of ~he index 3trip 320 h~u a shaped protrusion 323 ext~ t from ;t, the function of ~rhich b de~eribed 3ub~e~uently.
The connec~ing bJocl~ 340 i~clude~ a multiple of generally ~ymmetrical contacts 345 th~t have a b-~urcatet be~m at each c~d ~ODly the rear end being show~), eac~ bifurcated bean~ halrh~ a co~ductor receiYin~ 34B. The contae~ 345 are h~ld in 8 ~paced linear am~n6ement by a psir o~ mating :~ dielectric el~ment~ that combine to for~ ~ support member 350. The 3paced linear arrangeme~t of the contact3 345 i9 e33e~tially the same as that of the sloe3 325 ia the index strip 320.
The rear end of the contact3 345 exte~d beyond the rear end of the support member 350, and the rear end of the support member h~ recesse~
5 formed therein (~ot ~howll) of a shape to accommodate the teeth 324 of the index strip 320. Thu~ the connector block 340 b adapted to be joined to ~he index strip 320, and when 30 joi~ed, the bifurcated beam~ at the rear erlds of the contacts 345 respectively extend into the slots 325 betwee~L the teeth 324 of the index strip. As a result, the in~ulated conductor held i~ each slot is ~orced 10 into the slit 34~ of the b;~urcated beam extending i~to the ~lot. The bifurcated beam displ~ce~ the insulation from the conductor to make electrical connection to the conductor.
Th~ front end of the support member 3~0 generally replicates the front end of tke intex strip 320 in that it alJo has ~ multiplicity of pairs o~ oppo~ed 15 parallel extenting teeth 354. In addition, t~e front end~ of the teeth 354 are beveled to pro~ride ~-shaped entra~ce~ i~to slot~ 355 ltormed between adjacent pair~ of teeth. The connecti~g blo It 340 difrer~ from the i~dex strip 320 in that the bifurcated beam3 at the front ends of the contact3 345 are respectively located within the slots 355. Consequently, ~hen the connecti~g block 340 is 20 joined to the index str;p 320 to form the connector 300, conductors pre~ed into the ~lots 355 ar~ pre~ed into the ~lits of the bifurcated beams at the fro~t endof the co~tact~ 345 ant th~reby electrically connected to the conductor~ of the cable~ 2~D,200' (FIG. 1).
