Abstract: A system is provided for mounting an electrical connector to one side of a panel or other planar substrate. The connector includes a housing having a mounting face with a mounting boss projecting therefrom. The boss includes an enlarged head portion. The panel includes an aperture shaped for receiving the enlarged head portion therethrough such that the boss is rotatable in the aperture from a first insertion position and a second mounted position of the housing whereat the enlarged head portion overlaps the opposite side of the panel. Resilient detent latches on the housing snap into detent recesses in the panel automatically when the housing is in its second mounted position to lock the housing thereat.

Abstract: A programmable input-output electrical connector is provided for electrically coupling a plurality of conductors with an electronic component having a plurality of circuits. The connector includes a dielectric housing. A programming multi-contact bus is mounted in the housing. The bus includes a plurality of spring contacts normally biased into engagement with respective circuits on the electronic component. The spring contacts are individually selectively movable to inoperative positions out of engagement with the circuits. Latch devices are operatively associated with the spring contacts for positively holding each spring contact individually in its inoperative position.

Abstract: An insulation displacement termination system is provided for an input-output electrical connector which includes a dielectric housing having a top face and a bottom face with a terminal-receiving passage therebetween. At least one terminal includes an insulation displacement section generally at the bottom face of the housing for termination to an insulated electrical conductor through a lower mouth of the passage in the bottom face of the housing. The terminal includes a contact section projecting through an open upper end of the passage generally in the top face of the housing for engaging a complementary mating electrical component. The terminal is configured for insertion into the terminal-receiving passage through the lower mouth thereof.

Abstract: An electrical connector system is provided for electrically coupling a plurality of conductors with a printed circuit board. The system includes a main housing for mounting on one side of the printed circuit board, the board having an IC chip on the opposite side thereof. Main terminals are mounted on the main housing for coupling the conductors to circuits of the printed circuit board. A unitary secondary housing is adapted for mounting on the opposite side of the printed circuit board and includes an integral shield portion for covering the IC chip and providing electrostatic discharge protection therefor. Apertures are provided in the shield portion to allow for cooling of the IC chip. The unitary secondary housing includes at least one integral header portion defining a receptacle for receiving a complementary electrical connector.
