Abstract
Abstract Electrical connectors include a base (preferably formed of a plastics material) having an upright retaining wall. An electrically conductive bus plate has a base portion disposed adjacent a forward surface of the retaining wall so that a male terminal projects forwardly therefrom. A tubular housing is coupled to the base forwardly of the retaining wall via resilient tongue structures, and includes an opening through which the male terminal extends. When mounted to the base, a rear wall of the tubular housing will forcibly press the base portion of the male terminal against the retaining wall so as to rigidly hold the male terminal positionally within the tubular housing. In such a manner, the electrical connectors of the present invention minimize (if not eliminate entirely) distortion and/or positional skewing of the male terminal. A female plug body having female terminals may thus be inserted within the tubular housing so that the male terminal and female terminal are mated thereby establishing electrical communication with an external circuit, for example.
