ABSTRACT:
A sideswipe contact system for an add in PC card consisting of an apparatus for identifying the card as having a sideswipe connector and apparatus on a header for causing the header connectors to be electrically isolated from an inserted PC card unless the PC card is equipped with the sideswipe connectors. The header assembly includes a frame mechanically shaped to receive the card frame in an inserting relationship. A plurality of connector assemblies are movably mounted to the header frame. Each of the connector assemblies consists of an insulating standoff having substantially the same specified shape as the first cavity and fitting therein and a second electrical conductor adjacent to and smaller than the standoff. The plurality of connector assemblies are movable from a first position when the PC card is not inserted in the header frame to a second position when the card is fully inserted into the header. The movement from the first position to the second position is in a direction substantially orthogonal to the long dimension of the PC card. When the plurality of connectors assemblies are in the second position, each connector assembly fits into a matching connector receptacle and the first and second electrical conductors are in electrical contact. The plurality of connector assemblies move to a third position intermediate between the first and second positions if a PC card not having the plurality of connector receptacles is inserted into the header frame.
