Patent ID: 7284991

Claim:
A spring contact for interconnecting a circuit of an electronic device to a circuit on a planar mounting surface, comprising: a continuous ring formed from pliant material that extends around a geometric point, the ring having a circular body that encloses an hollow interior, the body including an interior surface and an exterior surface, at least one protuberance extending from the ring body exterior surface, the protuberance having two sides that lead from said ring body exterior surfaces to a point of intersection to thereby define an apex thereof, the circular body further having a base portion joined therewith, the base portion being disposed opposite said protuberance and including a flat, uninterrupted mounting surface for mounting said ring to a surface of a substrate, the apex of said ring moving linearly when said ring is subjected to a compressive force, said ring moving about at least one point of inflection disposed where said circular body is joined to said base portion.
