Abstract
Abstract A zero insertion force connector wherein a central member supports a plurality of electrical contacts at a first end with the free ends thereof mounted in two side members pivotally coupled to such central member. The manipulation of first distal ends of such side members controls the position of the second distal ends and in turn the electrical contacts. In a first position, the second distal ends are separated permitting external electrical contact to be non-engagingly moved between the electrical contacts of the connector. In the second position, the second distal ends bring the electrical contacts into mechanical and electrical contact with the inserted external electrical contacts. A latching member permits the second position to be maintained while various bias means and stops assist. The electrical contacts are of the insulation piercing type and engage the conductors of a flat cable when a cover forces the cable into the insulation piercing portion. The continuity of the joint can be probed through apertures in the side members.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
186 words
A zero insertion force connector, comprising: a center member supporting a plurality of deflectable electrical contacts and having at least one opening therein in communication with said contacts for receiving therein a plurality of conductive members; a first side member coupled to end portions of a first plurality of said electrical contacts; a second side member coupled to end portions of a second plurality of said electrical contacts; at least one of said side members having therethrough an aperture for passage of a cable, said aperture communicating with an uncoupled end of each of said first and second pluralities of electrical contacts; said side members each having corresponding first and second distal ends, said side members being pivotally coupled to said center member at a location between said first and second distal ends to allow movement of a first end toward and away from the corresponding other first end when a second end is moved respectively away from and toward the other corresponding second end, said first and second pluralities of electrical contacts being movable relative to said opening with the movement of said side members.
Claim 2
Dependent Claim
186 words
A zero insertion force connector, comprising: a center member supporting a plurality of deflectable electrical contacts and having at least one opening therein in communication with said contacts for receiving therein a plurality of conductive members; a first side member coupled to end portions of a first plurality of said electrical contacts; a second side member coupled to end portions of a second plurality of said electrical contacts; at least one of said side members having therethrough an aperture for passage of a cable, said aperture communicating with an uncoupled end of each of said first and second pluralities of electrical contacts; said side members each having corresponding first and second distal ends, said side members being pivotally coupled to said center member at a location between said first and second distal ends to allow movement of a first end toward and away from the corresponding other first end when a second end is moved respectively away from and toward the other corresponding second end, said first and second pluralities of electrical contacts being movable relative to said opening with the movement of said side members.
Claim 3
Dependent Claim
36 words
A connector according to claim 1 wherein said first distal ends of said first and second side members further comprise handle members for controlling the movement of the said second distal ends of said side members.
Claim 4
Dependent Claim
24 words
A connector according to claim 1, wherein said opening comprises a single aperture in communication with the first and second pluralities of electrical contacts.
Claim 5
Dependent Claim
26 words
A connector according to claim 1, including a plurality of openings, wherein each of said electrical contacts communicates individually with one of said plurality of openings.
Claim 6
Dependent Claim
33 words
A connector according to claim 1, wherein each contact of said pluralities of said first and second electrical contacts terminates at its uncoupled end in an insulation piercing portion extending into said apertures.
Claim 7
Dependent Claim
162 words
In combination: a supporting member having a plurality of conductive elements thereon; and a connector housing having a center member supporting a plurality of deflectable electrical contacts, said center member having at least one opening therein in communication with said contacts, said conductive elements extending into said opening and contacting said contacts, a first side member coupled to end portions of a first plurality of said electrical contacts; and a second side member coupled to end portions of a second plurality of said electrical contacts, said first and second side members each having handle ends and latching ends, said side members being pivotally coupled to said center member at a location intermediate said handle ends and said latching ends, said latching ends engaging a portion of said supporting member and thereby holding said side members at a fixed position relative to each other, said electrical contacts at such position being urged by said side members into pressing contact with said conductive elements.
Claim 8
Dependent Claim
162 words
In combination: a supporting member having a plurality of conductive elements thereon; and a connector housing having a center member supporting a plurality of deflectable electrical contacts, said center member having at least one opening therein in communication with said contacts, said conductive elements extending into said opening and contacting said contacts, a first side member coupled to end portions of a first plurality of said electrical contacts; and a second side member coupled to end portions of a second plurality of said electrical contacts, said first and second side members each having handle ends and latching ends, said side members being pivotally coupled to said center member at a location intermediate said handle ends and said latching ends, said latching ends engaging a portion of said supporting member and thereby holding said side members at a fixed position relative to each other, said electrical contacts at such position being urged by said side members into pressing contact with said conductive elements.
Claim 9
Dependent Claim
29 words
A combination according to claim 6, further including biasing means coupled between said handles ends for maintaining said latching ends in engagement with said portion of said supporting member.
Claim 10
Dependent Claim
23 words
