Abstract
Abstract A zero insertion force connector system with a top entry for improved interconnection with a component card and a component card positioner for providing an interconnectable structure that is useable with adjacent apparatus. The zero insertion force connector system includes a housing with a card guide channel having a top entry and a sliding cam system for interlocking the component card positioner and the component card in an improved manner. The component card positioner includes a card positioning structure with a tab cover structure and a card guide channel positioner for interaction with the sliding cam system of the zero insertion force connector system to properly interconnect the component card. The component card includes card contact tabs protected by a tab cover structure in the component card positioner and related to connector contacts positioned in the housing of the connector. The sliding cam system includes card retention lobes that mate with the lobe positioners in the card guide channel positioner for positioning the component card in an improved physical manner.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
237 words
A zero insertion force connector system for connection with a component card and a component card positioner comprising: said component card including contact tabs movable into said zero insertion force connector system, said zero insertion force connector system including, a housing with a top entry; and a card guide channel in said housing extending inward from said top entry, connector contacts positioned in said housing, said connector contacts movable to contact said contact tabs on said component card in said card guide channel, sliding cam means located and movable within said housing, said sliding cam means including positioning mating means for positioning said component card in said housing and for positioning said contact tabs relative to said connector contacts for electrically conductive contact therebetween, said sliding cam means contacting and actuating said contacts, said component card positioner mounted on said component card and connectable to said housing, said component card positioner including card guide channel positioner means connected to said component card and connectable in said card guide channel in said housing, said card guide channel positioner means for mating with said sliding cam means for proper seating of said component card and proper alignment of said contact tabs with said connector contacts; said zero insertion force connector system retaining said component card in a constrained manner to thereby resist component card movement and assure proper contact wiping action between said connector contacts and said contact tabs.
Claim 2
Dependent Claim
237 words
A zero insertion force connector system for connection with a component card and a component card positioner comprising: said component card including contact tabs movable into said zero insertion force connector system, said zero insertion force connector system including, a housing with a top entry; and a card guide channel in said housing extending inward from said top entry, connector contacts positioned in said housing, said connector contacts movable to contact said contact tabs on said component card in said card guide channel, sliding cam means located and movable within said housing, said sliding cam means including positioning mating means for positioning said component card in said housing and for positioning said contact tabs relative to said connector contacts for electrically conductive contact therebetween, said sliding cam means contacting and actuating said contacts, said component card positioner mounted on said component card and connectable to said housing, said component card positioner including card guide channel positioner means connected to said component card and connectable in said card guide channel in said housing, said card guide channel positioner means for mating with said sliding cam means for proper seating of said component card and proper alignment of said contact tabs with said connector contacts; said zero insertion force connector system retaining said component card in a constrained manner to thereby resist component card movement and assure proper contact wiping action between said connector contacts and said contact tabs.
Claim 3
Dependent Claim
26 words
A zero insertion force connector system as set forth in claim 1, wherein: said component card and said component card positioner are interconnected as a unit.
Claim 4
Dependent Claim
42 words
A zero insertion force connector system as set forth in claim 2, wherein: said component card positioner includes a top cover means for providing a dust cover and damage cover for said component card to protect against contact dust and contact damage.
Claim 5
Dependent Claim
47 words
A zero insertion force connector system as set forth in claim 3, wherein: said component card positioner interconnects with said housing and said sliding cam means for providing a rigid interconnection when mated to resist contact movement due to shock, vibration, thermal cycling and component card motion.
Claim 6
Dependent Claim
114 words
A zero insertion force connector system as set forth in claim 1, wherein said sliding cam means includes: a structural means movable horizontally in said housing, said structural means of said sliding cam means positionable for movement in a lower portion of said component card insertable vertically into said card guide channel, said component card and said insertion force connector, said component card and said card guide channel positioner means movable into said card guide channel and said positioner means movable into contact with said structural means of said sliding cam means, said sliding cam means including mating means on said structural means for orientating said contact tabs for wiping by said connector contacts.
Claim 7
Dependent Claim
41 words
A zero insertion force connector system as set forth in claim 5, wherein: said mating means includes mating retention lobes positioned on said structural means, said guide card channel positioner means includes means for accepting contact with said mating retention lobes.
