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).
Claims4
In combination with a contact of the type having:
- a one-piece inner sleeve having a forward mating portion, a rear wire receiving portion having a plurality of elongated slots therein and a middle portion;
- a rear sleeve telescopically mounted to the rear portion of the inner sleeve;
- and a forward sleeve telescopically mounted to the forward portion of said inner sleeve, the improvement comprising:
- a groove in the rear wire receiving portion of said inner sleeve with said elongated slots located in said groove;
- and
- a ferrule located in said groove.
A method of making a contact comprising the steps of:
- stamping from a single piece of metal a generally rectangular member having a plurality of fingers extending from one end, a groove in the opposite end portion, and a plurality of elongated slots located in said groove and having their longitudinal axis aligned with the longitudinal axis of said rectangular member;
- forming said piece of metal into a tubular member with said fingers extending from one end, a wire receiving portion extending from the opposite end;
- heating said tubular member to obtain a desired resiliency of said fingers;
- mounting a copper sleeve in said groove;
- telescopically mounting a sleeve to said wire receiving portion;
- and
- telescopically mounting a sleeve around said fingers.
In combination with an electrical socket type contact assembly of the type having:
- an inner sleeve stamped and formed from a single sheet of metal, said sleeve having a front mating portion, a rear wire receiving portion having a plurality of longitudinally extending slots, and a plurality of axially extending fingers in the front mating portion of the sleeve, said fingers resiliently deflectable in a radial direction;
- an intermediate sleeve telescopically mounted over said inner sleeve;
- and an outer sleeve telescopically mounted on the front portion of said intermediate sleeve, said outer sleeve having an enlarged portion that includes a forwardly facing shoulder, the improvement comprising:
- a groove in the rear wire receiving portion of said inner sleeve with said elongated slots located in said groove;
- and
- a ferrule located in said groove.
