Abstract
Abstract A zero insertion force electrical connector for multiple electrical connections includes a circuit board having a pair of contact strips on opposite faces thereof with opposed clamp members disposed adjacent the contact strips for biasing connector pins into engagement with the strips and a second connector member having a plurality of lined pins disposed for positioning on each side of the board adjacent the connector strips for contacting the connector strips upon biasing by the clamp members into engagement therewith.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
127 words
A zero force multiple pin electrical connector, said connector comprising: a first connector member including a central planar support member having a plurality of contacts aligned along at least one surface thereof; opposed clamping means disposed adjacent said contacts and spring-biased toward said contacts for biasing connector pins into engagement with the contacts; a second connector member having a plurality of aligned pins for engagement with said plurality of contacts; and means for enabling the clamping means to be wedged apart by the insertion of a separate tool to thereby enable placement of said plurality of aligned pins adjacent the contacts; wherein said support member is a printed circuit wiring board and said plurality of contacts comprises contact strips disposed adjacent to one edge of said board.
Claim 2
Dependent Claim
127 words
A zero force multiple pin electrical connector, said connector comprising: a first connector member including a central planar support member having a plurality of contacts aligned along at least one surface thereof; opposed clamping means disposed adjacent said contacts and spring-biased toward said contacts for biasing connector pins into engagement with the contacts; a second connector member having a plurality of aligned pins for engagement with said plurality of contacts; and means for enabling the clamping means to be wedged apart by the insertion of a separate tool to thereby enable placement of said plurality of aligned pins adjacent the contacts; wherein said support member is a printed circuit wiring board and said plurality of contacts comprises contact strips disposed adjacent to one edge of said board.
Claim 3
Dependent Claim
37 words
The multiple pin electrical connector of claim 1 when said first connector member includes a support housing attached to said printed circuit board and said clamp member comprises a clamping jaw pivotally mounted on said support member.
Claim 4
Dependent Claim
47 words
The multiple pin electrical connector of claim 2 wherein said printed wiring board includes a plurality of connector strips disposed on opposite faces thereof, said second connector member includes first and second rows of aligned pins for positioning on both sides of said board adjacent said connectors.
Claim 5
Dependent Claim
42 words
The multiple pin electrical connector assembly of claim 3 wherein said clamping means includes a pair of opposed jaw members pivotally mounted on said support housing and including spring means biasing said jaws toward and into an engagement with said contact strips.
Claim 6
Dependent Claim
26 words
The multiple pin connector assembly of claim 4 including guiding means for guiding said second connector member into proper position relative to said first connector member.
Claim 7
Dependent Claim
31 words
The multiple pin connector assembly of claim 5 wherein said guide means comprises a pair of spaced apart pins for engaging a pair of cooperating bores on said second connector member.
Claim 8
Dependent Claim
29 words
The multiple pin connector assembly of claim 5 wherein said guide means comprises a pair of slots and said second connector member includes means for guidably engaging said slots.
Claim 9
Dependent Claim
24 words
The electrical connector assembly of claim 7 wherein said clamping means includes a pair of spaced apart C-springs partially surrounding said clamping jaw members.
Claim 10
Dependent Claim
22 words
The multiple pin connector assembly of claim 4 when said plurality of contact pins are no greater than 0.018 inches in diameter.
