ABSTRACT:
A high contact force, high elastic response range pin-receiving electrical contact is provided in a pin-receiving contact including a base portion and a pair of spaced apart cantilever beams which extend forwardly from the base to a pin-receiving end. A pair of inwardly directed contact surfaces are defined on each cantilever beam facing the opposed beam for slideably, electrically engaging an inserted pin terminal. In accordance with the invention, a resilient beam support member extends from and interconnects the pin-receiving ends of the cantilevered beams. The resilient beam support member provides a significantly improvement in the elastic response range of the pin-receiving contact by enabling each cantilevered beam to endure a greater outward displacement before a minimum yield in the beam occurs while providing a greater normal force against the pin. In a preferred embodiment, the resilient beam support member is a planar U-shaped spring which extends parallel to and adjacent the cantilevered beams and extends rearwardly from the front pin-receiving end of the contact.
