Abstract: A zero insertion force (ZIF) electrical connector for a pin grid array (PGA) device includes upper and lower housings movable in a contact mating direction between a free or contact insertion position and a lock or contact mated position. Pin terminals of the PGA device extend through openings in the upper housing and into cavities in the lower housing. Each cavity includes a resilient terminal having a mounting portion, a leaf spring portion parallel to the direction of contact mating, a free end portion and a contact structure between the leaf spring portion and the free end portion. A pin engagement surface on the contact structure confined substantially within the lateral bounds of the leaf spring portion has a flat portion and a ramp portion inclined relative to the contact mating direction and causes the leaf spring portion to flex in a direction perpendicular to the mating direction.

Abstract: An ejector mechanism is provided for ejecting an IC card from a header connector which has a mating end, a terminating end and first and second opposite sides extending between the ends. A generally L-shaped ejector frame is adapted to be mounted about the header connector with a base leg of the L-shaped frame along the terminating end of the header connector and a side leg along one side of the header connector. The side leg has a channel therein. An ejector lever is pivotally mounted on at least one of the header connector or the ejector frame and has a first lever end and a second lever end. The second lever end is adapted to eject the IC card from the header connector. An elongated push-rod is reciprocally mounted in the channel and has a first rod end pivotally associated with the first lever end of the ejector lever and a second rod end for manual actuation to effect pivoting of the eject lever and ejection of the IC card.

Abstract: An electrical connector is provided for surface mounting along an edge of a circuit board in an edge straddling configuration. The circuit board has a plurality of contact pads spaced along opposite faces of the board near the edge thereof. The connector includes a dielectric housing and a plurality of terminals mounted on the housing with solder tails projecting from the housing generally in two rows to define an elongate board-receiving mouth for receiving the edge of the circuit board. The contact pads are adapted to receive soft solder paste thereon prior to insertion of the board into the mouth between the two rows of solder tails.
