ABSTRACT:
A generally cylindrical spring bushing formed of resilient, conductive sheet metal folded to form a generally cylindrical exterior with a coaxially re-entrant section within the shell forming said exterior for gripping a coaxially emplaced pin, such as a typical square tail employed as a wire-wrap terminal. The bushing, because of its re-entrant coaxial folded shape, is capable of exerting a relatively large spring force against the hole or bore in a back-plane and also against the wire-wrap pigtail inserted therethrough, within an axial length not exceeding the individual back-plane thickness.
