Abstract
Abstract A printed wiring board connector is provided with a plurality of spring contacts and is mounted in a bracket such that it is rotatable about a longitudinal axis. The insertion of a printed wiring board operates to rotate the connector whereby the spring contacts engage the circuits of the board. The forces necessary to insert and extract the board are thereby substantially reduced.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
100 words
A printed wiring board connector comprising an elongate, electrically insulative, unitary connector body having a longitudinal cavity therein adapted to receive a printed wiring board, a plurality of electrically conductive spring contact elements disposed through said connector body and extending into said longitudinal cavity, means for pivotally mounting said connector body such that said connector body is rotatable with respect to said mounting means about a longitudinal axis thereof whereby insertion of a printed wiring board into said cavity operates to rotate said connector body to thereby drive said spring contact elements into electrical contact with said printed wiring board.
Claim 2
Dependent Claim
100 words
A printed wiring board connector comprising an elongate, electrically insulative, unitary connector body having a longitudinal cavity therein adapted to receive a printed wiring board, a plurality of electrically conductive spring contact elements disposed through said connector body and extending into said longitudinal cavity, means for pivotally mounting said connector body such that said connector body is rotatable with respect to said mounting means about a longitudinal axis thereof whereby insertion of a printed wiring board into said cavity operates to rotate said connector body to thereby drive said spring contact elements into electrical contact with said printed wiring board.
Claim 3
Dependent Claim
47 words
A connector as recited in claim 1 wherein said mounting means further includes means for locking said connector body in rotation when said printed wiring board is fully inserted into said cavity to thereby retain said spring contact elements in electrical contact with said printed wiring board.
Claim 4
Dependent Claim
21 words
A connector as recited in claim 1 wherein said spring contact elements are fixed to and rotatable with said connector body.
Claim 5
Dependent Claim
51 words
A connector as recited in claim 3 further including a plurality of connecting contacts fixed to said mounting means, one associated with each of said plurality of spring contact elements, and disposed such as to engage said spring contact element when said printed wiring board is fully inserted into said cavity.
Claim 6
Dependent Claim
95 words
A connector as recited in claim 1 wherein said connector body further includes a longitudinal slot in the wall thereof opposite the entrance of said longitudinal cavity, and said spring contact elements are fixed to said mounting means, extend through said longitudinal slot and engage said connector body at the edge of said entrance of said longitudinal cavity whereby said spring cOntact elements are engaged and driven into electrical contact with said printed wiring board by opposed edges of said cavity and said slot when said printed wiring card is fully inserted into said cavity.
Claim 7
Dependent Claim
37 words
A connector as recited in claim 5 further including a ridge formed in said spring contact element engaging edge of said longitudinal slot to thereby provide a substantially point contact between said contact element and said edge.
