Abstract
Abstract This invention relates to electrical connectors and more particularly to a three-piece socket type electrical contact for the connector. The socket type contact includes an inner sleeve (10) stamped and formed from a single sheet of beryllium copper metal, the sleeve having a rear wire receiving portion that includes a groove (11) having a plurality of elongated slots located in said groove; a copper ferrule (20) located in said groove; and a stainless steel rear sleeve (40) telescopically mounted over the rear portion of the inner sleeve (10) and said ferrule (20).
