An electrical accessory plug for insertion in the socket of an automobile cigar lighter receptacle of the type provided with a grounded shell and live resilient clip contact fingers which have a rigid mounting. The plug has electrical conductor strips for connection to an electrical cord, and has at its inner end a retainer shoulder adapted to engage and to be fractionally em- braced and retained by the live clip contact fingers of the cigar lighter receptacle. A spring-biased contact plunger at the inner end of the plug is connected to one of conductor strips. The plunger is adapted for abutting engagement under spring pressure, with the rigid mount- ing of the contact fingers of the cigar lighter recep- tacle when the plug body is positioned deeply in the receptacle. The advantage of the present construction over the devices of the prior art is that improved con- tact pressures are realizeable, with reduced contact heating and resultant contact degeneration. In addition, the clip contact fingers are not required to carry any of the current being supplied to the accessory.
