Abstract
Abstract An entirely zero insertion/retraction force connector having a mechanism for receiving the conductor terminals of a device inserted therein. The connector includes means having conductor terminals which are separable by an actuating mechanism which responds to insertion of said device into the connector for receiving said device terminals without engagement between the connector terminals until the inserted device is fully positioned in the connector at which time resilient means urges the connector terminals toward one another thus electrically connecting (clamping) the device terminals therebetween. The force necessary to insert and move the inserted device to final position has no relationship to terminal contact pressure which is a function only of the force of the resilient means and in one embodiment of the invention there is no wiping force involved. In another embodiment, the camming means may be arranged to permit a slight wiping action of the terminals, if desired, without any major structural change to the connector.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
152 words
A zero insertion/retraction connector for connecting terminal conductors of an electronic device to other electronic devices comprising, means for receiving the device, actuable means in said receiving means including: means supporting a first set of electrical conductor terminals, means supporting a second set of electrical conductor terminals, resilient means for urging said second support means towards said first support means when said device is absent from said receiving means, means for displacing said second support means against the urging of said resilient means as said device is being inserted in said receiving means to permit the terminals of said device to move between the terminals of said first and second support means but out of contact therewith, and means enabling said resilient means to again urge said second support means toward said first support means to effect the mating of said terminals on said device with said terminals on said support means.
Claim 2
Dependent Claim
152 words
A zero insertion/retraction connector for connecting terminal conductors of an electronic device to other electronic devices comprising, means for receiving the device, actuable means in said receiving means including: means supporting a first set of electrical conductor terminals, means supporting a second set of electrical conductor terminals, resilient means for urging said second support means towards said first support means when said device is absent from said receiving means, means for displacing said second support means against the urging of said resilient means as said device is being inserted in said receiving means to permit the terminals of said device to move between the terminals of said first and second support means but out of contact therewith, and means enabling said resilient means to again urge said second support means toward said first support means to effect the mating of said terminals on said device with said terminals on said support means.
Claim 3
Dependent Claim
35 words
The connector as claimed in claim 1 wherein said actuable means includes fork means the tynes of which are engaged by said inserted device for slidable movement relative to said first and second support means.
Claim 4
Dependent Claim
34 words
The connector as claimed in claim 2 wherein said actuable means includes camming means which engages said first and second supporting means to displace said second supporting means relative to said first supporting means.
Claim 5
Dependent Claim
16 words
The connector as claimed in claim 3 wherein said camming means is located on said fork.
Claim 6
Dependent Claim
28 words
The connector as claimed in claim 4 further including plunger means movable in response to movement of said fork means and including camming means on said plunger means.
Claim 7
Dependent Claim
40 words
The connector as claimed in claim 5 wherein said actuable means further includes pivotal means operatively connecting said fork with said plunger means and arranged to displace the fork means and the plunger means in opposite directions from each other.
Claim 8
Dependent Claim
31 words
The connector as claimed in claim 6 further including lamp means for indicating when the terminals of said inserted device is in an electrical contact with the terminals of said connector.
Claim 9
Dependent Claim
18 words
The connector as claimed in claim 7 further including guide means for said device within said receiving means.
