Abstract: A socket contact for an electrical connector is disclosed which includes a contact body, a tubular spring member snapped onto the contact body and a protective sleeve telescopically disposed over the spring member. The contact body includes an annular groove and the spring member includes a plurality of circumferentially spaced tabs. The tabs are formed over the groove through the sleeve to prevent axial movement of the spring member relative to the contact body, whereby a highly reliable electrical joint is made between the spring member and the contact body to avoid electrical discontinuities that might otherwise result.

Abstract: This invention is an electrical contct that includes an inner sleeve (10) that is stamped and formed from a single sheet of metal and is characterized by a plurality of apertures (11) in the sleeve (10) that have an axis of symmetry (11a) or a straight side (13) that is at an acute angle with the central axis (10a) of the sleeve.

Abstract: A socket contact for electrical connectors consisting of a contact liner sleeve (16) with a rear sleeve (14) and inner and outer front sleeves (12, 10) assembled to the front and to the contact liner sleeve (16) with the outer sleeve (10) rear portion thereof formed over the rear face (40) of the inner front sleeve (12) to form a well defined retention shoulder (48).

Abstract: A slot (11) or a cutaway portion that includes an end surface (41) in an outer sleeve (10 or 40, 50) to provide an opening for a projection (25) in an inner sleeve so that the inner sleeve (20) may be located in a predetermined position within the outer sleeve (10) or sleeves (40, 50). A final outer sleeve (30) then is formed over a shoulder (42) of outer sleeve (40) to lock all the sleeves together. This eliminates the need for crimping the sleeves together.

Abstract: A socket contact (10) for electrical connectors and method of manufacture comprised of a contact liner (12), a front guide sleeve (14), and a rear sleeve (16) each of said guide sleeve (14) and rear sleeve (16) interfit over the contact liner (12) with a slight overlap (42) at the approximate midsection of the contact liner (12). The guide sleeve (14) is enabled to be interfit with both the contact liner (12) and the rear sleeve (16) by a crimp (44) formed adjacent the rear end (40) of the guide sleeve (14). A fillet weld (48) is applied at the shoulder (46) created by the guide sleeve (14) overlapping the rear sleeve (16) which weld reinforces the midsection of the socket contact (10).

Abstract: A two piece contact assembly characterized by a method of making the assembly by press fitting a stamped and formed inner sleeve (10) into a cold drawn tubular member (20) to provide an electrical contact having a seamless pin type contact area.

Abstract: An electrical split sleeve socket contact (10) is disclosed including a plurality of tines (26) formed by slots (30) axially extending from the front of a contact sleeve (12) in which an increased contact pressure is achieved by an axially extending central rib (44) and inwardly crimped sides (46) of each of the contact tines (26) to provide three line contact of each tine with the pin contact (22) and increase the flexural rigidity of each of the tines (26) (FIG. 3).

Abstract: A method of making a gold plated socket contact characterized by heat treating in a vacuum furnace the previously formed and partially gold plated inner sleeve (10) of a three piece contact assembly.

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).

Abstract: In order to prevent the rotation of an electrical contact 30 within a connector assembly housing 3 the contact 30 is provided with a plurality of radial fins 37 which are located within a space between resiliently deflectable fingers 21 which are part of the contact retaining insert 20. Because the contact 30 does not rotate, the winding of a wire around the wire receiving portion 38 of the contact is facilitated.

Abstract: This invention is a three piece contact assembly of the type having an inner sleeve (10), a forward sleeve (20), and a rear sleeve (30), wherein the inner sleeve is characterized by a dual thickness. The forward portion of the inner sleeve 10 has a thickness (T) greater than the thickness (t) of the rear wire receiving end thereby strengthening the deflectable fingers (14) at the mating end of the inner sleeve (10).
