ABSTRACT:
A two-piece electrical receptacle terminal for receiving a male terminal. The receptacle terminal includes a spring, having a predetermined shape, which is confined within an integrally formed housing. During insertion of the male terminal into the housing, the spring is deflected from the predetermined shape. The spring is constructed of a metal which exhibits a memory, evoked by heating, predisposing the deflected spring into its predetermined shape. Heating can be accomplished by ohmic self-heating.
