Abstract
Abstract An electrical connector (10) for terminating a multi-conductor cable (100) has a housing (12) including a cable terminating face (18), an opposed mating face (16) and opposed end walls (24,26) having latch means (58,60) thereon. The cable terminating face (18) has major edges and minor edges, with the minor edges contiguous with the end walls (24,26). The major edges extend laterally beyond the profile of the mating face (16). The cable terminating face (18) has a rib (44,46) extending along the major edges, upstanding from the cable terminating face (18). A plurality of contacts (30) are secured in the housing (12) and have respective insulation displacement plates (34) extending from the cable terminating face (18). A terminating cover (14) defines an inner surface (80) and major side edges and has latch arms (86, 88) at opposite ends thereof adapted to engage the latch means (58,60) on the connector housing (12) to retain the terminating cover (14) on the housing (12). The terminating cover (14) has an off-set surface (94,96) recessed from the inner surface (80) along the major side edges that cooperates with the rib (44,46) to provide a space through which a ribbon cable (100) terminated to the connector (10) passes and to engage the cable (100) to provide strain relief thereto.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
181 words
An electrical connector for terminating multiconductor cable, comprising: a housing having a cable terminating face, an opposed mating face and opposed end walls having latch means thereon, said cable terminating face having major edges and minor edges, said minor edges contiguous with said end walls, said major edges extending beyond the profile of said mating face, said mating face having a rib extending along each of said major edges, said ribs upstanding from said cable terminating face; a plurality of contacts in said housing, said contacts having respective conductor receiving portions extending from said cable terminating face; a terminating cover defining an inner surface, major side edges and having latch arms at opposite ends thereof extending to respective distal ends, said latch arms adapted to engage said latch means to retain said cover on said housing, said terminating cover having an off-set recessed from said inner surface along the major side edges thereof cooperable with the rib to provide a space therebetween for passage of a cable terminated on said connector and to engage said cable to provide strain relief thereto.
Claim 2
Dependent Claim
181 words
An electrical connector for terminating multiconductor cable, comprising: a housing having a cable terminating face, an opposed mating face and opposed end walls having latch means thereon, said cable terminating face having major edges and minor edges, said minor edges contiguous with said end walls, said major edges extending beyond the profile of said mating face, said mating face having a rib extending along each of said major edges, said ribs upstanding from said cable terminating face; a plurality of contacts in said housing, said contacts having respective conductor receiving portions extending from said cable terminating face; a terminating cover defining an inner surface, major side edges and having latch arms at opposite ends thereof extending to respective distal ends, said latch arms adapted to engage said latch means to retain said cover on said housing, said terminating cover having an off-set recessed from said inner surface along the major side edges thereof cooperable with the rib to provide a space therebetween for passage of a cable terminated on said connector and to engage said cable to provide strain relief thereto.
Claim 3
Dependent Claim
18 words
An electrical connector as recited in claim 1 wherein the interior surface of said terminating cover is fluted.
Claim 4
Dependent Claim
83 words
An electrical connector as recited in claim 1 further comprising a rib on each housing end wall parallel to the conductor receiving portions of said contacts and a complementary channel on an inside wall of each latch arm, whereby the ribs and channels cooperate during movement of the termination cover from a pretermination position to a termination position, such as during termination of a ribbon cable to the connector, to guide the terminating cover parallel to the conductor receiving portions of the contacts.
Claim 5
Dependent Claim
52 words
An electrical connector as recited in claim 3 wherein the one rib and its complementary channel are wider than the other rib and channel, whereby the terminating cover and housing are polarized relative to each other in that the terminating cover can only be received on the housing in a predetermined orientation.
Claim 6
Dependent Claim
154 words
An electrical connector as recited in claim 1 wherein said terminating cover channels have extending thereacross near the distal end thereof a cross bar having a latch shoulder, each said rib having extending outwardly therefrom at least two spaced latching protrusions cooperable with said cross bar to secure the terminating cover to the housing in first and second latched positions; in the first latched position the inner surface of the terminating cover is spaced from the conductor receiving portions of the contacts to permit insertion and alignment of a cable for termination, the cross bar is positioned between and engaging said at least two latching protrusions, said terminating cover being movable from the first position toward the cable terminating face to terminate a cable, the cable terminating cover securing the cable in a terminated position at the second latched position, with said cross bar engaging one of said at least two spaced latching protrusions.
Claim 7
Dependent Claim
190 words
An electrical connector for terminating multiconductor cable, comprising: a housing having a cable terminating face, an opposed mating face and opposed end walls having latch means thereon, said cable terminating face having major edges and minor edges, said minor edges contiguous with said end walls, at least one of said major edges extending beyond the profile of said mating face, said mating face having a rib extending along said at least one major edge, said rib upstanding from said cable terminating face; a plurality of contacts in said housing, said contacts having respective conductor receiving portions extending from said cable terminating face; a terminating cover defining an inner surface, major side edges and having latch arms at opposite ends thereof extending to respective distal ends, said latch arms adapted to engage said latch means to retain said cover on said housing, said terminating cover having an off-set recessed from said inner surface along at least one major side edge thereof, said off-set cooperable with the rib to provide a space therebetween for passage of a cable terminated on said connector and to engage said cable to provide strain relief thereto.
Claim 8
Dependent Claim
