ABSTRACT:
An electrical connector part is disclosed of the type comprising a cylindrical housing having contact terminals therein which are mated with complementary terminals in a complementary connector part when the two parts are coupled. A cylindrical coupling ring is rotatably mounted on the housing and has on its internal surface coupling means, such as helical slots, for cooperation with a pin on the complementary connector part. The coupling ring is a composite member comprising an outer metallic cylindrical portion and a relatively thick inner metallic cylindrical portion adjacent to the leading edge of the coupling ring. The slots are provided in the inner cylindrical portion of the coupling ring and are produced by stamping slots in a flat blank, forming the blank into a cylindrical shape, and then assembling it to the outer cylindrical portion of the coupling ring. The invention eliminates the need for a separate metallic shell in surrounding relationship to the housing.
