Abstract
Abstract A zero-insertion-withdrawal force connector is disclosed. The contact fingers thereof are arranged in two series at right angles to each other. By a single movement in one direction of an operating lever two cam, or actuating, motions are produced for causing, essentially simultaneous, engagement of two series of contact fingers.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
207 words
A zero-insertion-withdrawal force connector assembly comprising: a first connector block having first and second contact fingers projecting therefrom, the planes of said first contact fingers being disposed at right angles to the planes of said second contact fingers, a second connector block having third and fourth contact fingers projecting therefrom, the planes of said third contact fingers being disposed at right angles to the planes of said fourth contact fingers, said second connector block being adapted to be disposed adjacent said first connector block with said third contact fingers lying alongside said first contact fingers but out of contact therewith and with said fourth contact fingers lying alongside said second contact fingers but out of contact therewith, first means for moving said first and third contact fingers into engagement with each other in one direction, second means for moving said second and fourth contact fingers into engagement with each other at right angles to the movement of said first means, relative movement interengaging means between said first means and said second means for effecting movement of said first means at right angles to the movement of said second means and in response thereto when said second means is moved, and third means for moving said second means.
Claim 2
Dependent Claim
207 words
A zero-insertion-withdrawal force connector assembly comprising: a first connector block having first and second contact fingers projecting therefrom, the planes of said first contact fingers being disposed at right angles to the planes of said second contact fingers, a second connector block having third and fourth contact fingers projecting therefrom, the planes of said third contact fingers being disposed at right angles to the planes of said fourth contact fingers, said second connector block being adapted to be disposed adjacent said first connector block with said third contact fingers lying alongside said first contact fingers but out of contact therewith and with said fourth contact fingers lying alongside said second contact fingers but out of contact therewith, first means for moving said first and third contact fingers into engagement with each other in one direction, second means for moving said second and fourth contact fingers into engagement with each other at right angles to the movement of said first means, relative movement interengaging means between said first means and said second means for effecting movement of said first means at right angles to the movement of said second means and in response thereto when said second means is moved, and third means for moving said second means.
Claim 3
Dependent Claim
25 words
The zero force connector according to claim 1 wherein said first means, said second means and said interengaging means are disposed in the same plane.
Claim 4
Dependent Claim
24 words
The zero force connector according to claim 1 wherein said third means comprises first cam means on said second means and cam operating means.
Claim 5
Dependent Claim
28 words
The zero force connector according to claim 3 wherein said interengaging means comprises second cam means on said second means and third cam means on said first means.
Claim 6
Dependent Claim
23 words
The zero force connector according to claim 3 wherein said first cam means are disposed in the same plane as said second means.
Claim 7
Dependent Claim
30 words
The zero force connector according to claim 3 wherein said cam operating means includes surfaces for engaging said first cam means, and including means for operating said cam operating means.
Claim 8
Dependent Claim
53 words
The zero force connector according to claim 6 including first housing means for said first connector block, said first means, said second means and said cam operating means, and a second housing for said second connector block, said second housing being adapted to operatingly support said means for operating said cam operating means.
