Abstract:
A method for forming a fastener for use in an electrical connector to enable the connector to fixedly connect with a mated connector by a bolt of the mated connector threadedly engaging with the fastener, comprising the following steps:(a) stamping a first rectangular metal plate to have a first face defining a number of parallel V-cuts thereon, an opposite second face with an elongate flange on a lower edge thereof, and two lateral sides between the first and second faces;(b) bending the first plate to obtain a sleeve with the V-cuts forming a thread in the sleeve, the two lateral sides contacting each other, and the elongate flange forming a circular flange;(c) stamping a second rectangular plate to obtain a base defining a first hole between a top and a bottom face of the base of a diameter slightly smaller than that of the circular flange, a circular protrusion projecting into the first hole to define a second hole having a diameter slightly smaller than that of the sleeve, the protrusion being located near the top face; and(d) assembling the sleeve to the base by extending the sleeve through the first and second holes of the base to reach a position where the sleeve has an interferential engagement with the protrusion and the flange is received within the first hole by an interferential fit.
