Abstract
Abstract An electrical connector assembly which includes an insulator housing having a pair of parallel rows of openings passing from a front face to a back face thereof. The openings are adapted to receive terminal contacts which lock in place. The locking means between the terminal contacts and the housing are available for unlocking through adjacent access means from the top and bottom surfaces of the housing. A flat thin extension extends from the back face of the housing between the rows of the pair of rows of openings. Clamp means are provided on each side of the extension to provide a strain relief for the wires to which the contacts are attached. The clamp means also serve as a common grounding conductor.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
175 words
An electrical connector assembly comprising: an insulator housing have a pair of parallel rows of openings passing from a front face to a back face of said housing; a plurality of access means in the top and bottom surfaces of said housing each providing access to a respective one of said openings of the adjacent row of said openings; terminal contacts adapted for insertion in each of said openings of said pair of rows of openings; locking means for locking each of said terminal contacts in its respective openings, said locking means being releasable through said access means thereby freeing said terminal contacts for removal from said openings; an extension extending from the back face of said housing between said rows of said pair of rows of openings; and clamp means for clamping wires attached to said terminal contacts to a respective side of said extension thereby moving the strain point from the connection point between the wire and terminal contact at the opening in the back face of said housing to said clamp means.
Claim 2
Dependent Claim
175 words
An electrical connector assembly comprising: an insulator housing have a pair of parallel rows of openings passing from a front face to a back face of said housing; a plurality of access means in the top and bottom surfaces of said housing each providing access to a respective one of said openings of the adjacent row of said openings; terminal contacts adapted for insertion in each of said openings of said pair of rows of openings; locking means for locking each of said terminal contacts in its respective openings, said locking means being releasable through said access means thereby freeing said terminal contacts for removal from said openings; an extension extending from the back face of said housing between said rows of said pair of rows of openings; and clamp means for clamping wires attached to said terminal contacts to a respective side of said extension thereby moving the strain point from the connection point between the wire and terminal contact at the opening in the back face of said housing to said clamp means.
Claim 3
Dependent Claim
50 words
An electrical connector assembly according to claim 1, wherein said clamp means is located on said extension at sufficient distance from the back face of said housing to allow easy insertion and withdrawal of said terminal contacts into and out of said openings through the back face of said housing.
Claim 4
Dependent Claim
49 words
An electrical connector assembly according to claim 1, wherein said wires are coaxial wires; said clamp means being an electrical conductor contacting the ground plane shield of said coaxial cable; and a common grounding connection extending from said conductive clamp means to a terminal contact within said connector housing.
Claim 5
Dependent Claim
81 words
An electrical connector assembly according to claim 3, wherein said clamping means comprises a clamp bar attachaBle to said extension having tin plating along the surface of the clamp bar which contacts the wires to provide a good conducting surface; and tin plating on the portion on the ground plane shield of said coaxial wire contacted by said clamp bar so that a good electrical connection is made between said clamp bar and said ground plane shield of said coaxial wire.
Claim 6
Dependent Claim
55 words
An electrical connector assembly according to claim 1, wherein a shelf is provided extending a short distance from the back face of said housing contiguous with the inner surface of said openings so that the spring leaf of the terminal contact can be placed thereon as a guide means for easy insertion into said opening.
