<p>CONNECTOR RECEPTACLE FOR ELECTRIC CIGAR LIGHTER An electrical connector receptacle for an automotive electric cigar lighter of the type having at its rear, a socket with a central terminal post and an annular electrically-conductive current-carrying sleeve. The receptacle comprises a slab-like body of molded insulating material having opposite grip surfaces to facilitate its installation, and having a generally U-shaped configuration. Between the two legs of the body is a space which provides clearance for the annular sleeve, one leg having a recess that carries a tubular contact terminal adapted to slip over the central terminal post of the socket, this being the "hot" side of the circuit. The other, outer leg constituting the ground side of the circuit, carries a spring contact finger having a bowed configuration with its center portion being cooperable with and juxtaposed to the sleeve of the socket, so as to have electrical connection thereto when the connector receptacle is installed. The spring contact finger and the tubular contact terminal of the center leg are generally coextensive with one another, and the force of the sleeve acting against the contact finger is balanced by a counteracting force of the central post of the socket on the tubular contact so as to maintain adequate pressure between the contact finger and sleeve. The advantage of the present invention over the devices of the prior art is that it constitutes an especially compact and reliable receptacle which can be quickly installed or released and which is capable of handling the relatively heavy electrical current normally associated with cigar lighter devices.</p> |
