Abstract
For use with plugs of the type designed for insertion into cigar lighter receptacles. The new receptacle uses a plastic part as the housing and insulator. A simple open seamed brass cylinder is inserted inside a well of the housing to serve as the negative contact. The positive contact in the center of the bottom of the well is affixed with a rivet. The negative terminal is affixed to the sleeve, and the positive terminal is attached with the rivet. When used as an extension cord, a snap on end cap protects the electrical connections. When used as a portion of a wall receptacle as in recreational vehicles, the plastic housing extends beyond the terminals to prevent a short to the outer metal skin of the vehicle. The receptacle may also be used for a cigar lighter, by using a bi-metal element for the positive contact, and using a high temperature plastic for the housing.
