Socket contact for electrical connector and method of manufacture

Claim 1

A socket contact for an electrical connector comprising a generally cylindrical conductive socket body formed with a rear end, that includes a terminal portion adapted to receive the bared end of an electrical conductor, said socket body also formed with a forward end that includes a generally cylindrical projection; a conductive tubular spring member having an internal diameter at one end received over said generally cylindrical projection to be fit thereto, and slotted to form spring fingers; and a tubular guide sleeve received over both said spring member and said cylindrical projection characterized by said cylindrical projection being formed with a reduced diameter section and a larger diameter section adjacent thereto at the outer end thereof, with both said one end of said spring member and one end of said guide sleeve crimped radially inward towards said reduced diameter section to secure said spring member and guide sleeve to said socket body, said larger diameter section of said cylindrical projection formed with an intermediate groove and wherein said spring member is formed with a circumferential crimp received into said groove to improve the electrical connection therebetween and provide a locating feature at assembly.

Claim 5

A method of manufacturing a socket contact for an electrical connector comprising the steps of forming from conductive material a generally solid cylindrical socket body having a terminal portion at a rear end adapted to receive the bare end of an electrical conductor to be joined thereto, and forming said socket body with a generally cylindrical projection at the forward end; forming of said socket body formed with a groove intermediate said larger diameter section, and forming said spring member with a circumferential crimp adjacent said one end thereof extending radially inward from said internal diameter; forming a tubular spring member configured with an internal diameter at a rear end adapted to be fit over said projection and formed with slots at the forward end thereof to provide spring fingers; forming a tubular guide sleeve having an inside diameter configured to be fit over said spring member; assembling said spring member onto said projection of said socket body with said internal diameter fit over said projection and with said crimp disposed in said intermediate groove in said larger diameter section of said projection; assembling said guide sleeve over said spring member with said rear end thereof fit over and axially aligned with said rear end of said spring member, characterized by the steps of forming said projection with a larger diameter section at the forward end of said projection and an adjacent reduced diameter section and the step of simultaneously crimping each of said rear ends of said spring member and guide sleeve respectively radially inward towards said reduced diameter section of said projection to secure said spring member and guide sleeve to said socket body.

Claim 6

A method of manufacturing a socket contact for an electrical connector comprising the steps of forming from conductive material a generally solid cylindrical socket body having a terminal portion at a rear end adapted to receive the bare end of an electrical conductor to be joined thereto, and forming said socket body with a generally cylindrical projection at the forward end; forming of said socket body formed with a groove intermediate said larger diameter section, and forming said spring member with a circumferential crimp adjacent said one end thereof extending radially inward from said internal diameter; forming a tubular spring member configured with an internal diameter at a rear end adapted to be fit over said projection and formed with slots at the forward end thereof to provide spring fingers; forming a tubular guide sleeve having an inside diameter configured to be fit over said spring member; assembling said spring member onto said projection of said socket body with said internal diameter fit over said projection and with said crimp disposed in said intermediate groove in said larger diameter section of said projection; assembling said guide sleeve over said spring member with said rear end thereof fit over and axially aligned with said rear end of said spring member, characterized by the steps of forming said projection with a larger diameter section at the forward end of said projection and an adjacent reduced diameter section and the step of simultaneously crimping each of said rear ends of said spring member and guide sleeve respectively radially inward towards said reduced diameter section of said projection to secure said spring member and guide sleeve to said socket body.
