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. The contact structure and the free end portion are offset from the leaf spring portion in the direction opposite to the direction of spring flexing.
