ABSTRACT:
A three piece electrical contact assembly that includes an inner sleeve that is stamped and formed into a tubular shape from a flat sheet of metal. The electrical contact assembly provides a secure electrical and mechanical connection when crimped to a wire without the need for welding or brazing a seam (31) that results from forming the contact. The contact assembly includes: an inner sleeve having an enlarged middle portion (35) having forwardly and rearwardly facing shoulders for retention of the contact in a connector insert and a plurality of axially arranged slots (32) arranged in the wire receiving end of the contact assembly allow the contact assembly to distort symmetrically when a wire is crimped inside the contact; and a first and second outer sleeve (10,20) telescopically located over the front and rear portions, respectively, of the inner sleeve.
