Abstract
Abstract A method of making a hermaphroditic electric contact including steps of forming a tubular body with fingers having offset blade portions extending longitudinally from one end portion of the body, bending the blade portions to face radially inwardly of the body, cutting openings in the body to form medial wall portions, forcing the opposite ends of the tube together and allowing the wall portions to bend outwardly and form U-shaped locking shoulders, the locking shoulders being axially compressible during twisting fitment of the contact into a retention shoulder formed in a connector passage.

A method of making an electrical connector assembly of the type including a dielectric housing having a passage therethrough for receiving a hermaphroditic electrical contact comprised of a tubular body, the steps including: providing a plurality of radially spaced, longitudinally extending engagement fingers on a forward end portion of the tubular body, each finger including at its distal end portion an offset blade portion; bending said offset blade portions radially inwardly so that ends converge towards but do not reach the central axis of the tubular body; forming generally U-shaped locking shoulders medially around the tubular body, said shoulders cooperating to allow said tubular body to undergo longitudinal compression; forming a number of retention shoulders on said dielectric housing for mounting the contact within the passage, each adjacent pair of retention shoulders being separated by a slot and the number of retention shoulders being equal in number to the number of locking shoulders, each retention shoulder being formed with a tapered entry ramp leading to a groove sized to receive one said locking shoulder; fitting the tubular body into the passage so that the locking shoulders fit between the slots and are disposed adjacent to the entry ramps; and twisting the body so that the locking shoulder is forced up the ramp and into the groove.
