Abstract
An electrical cigar lighter for automotive vehicles is provided with a socket assembly and a plug assembly including a heater element adapted to be electrically heated when the plug assembly is in a connected position within the socket assembly. Electrical circuitry is provided within the socket assembly to effect electrical heating of the heater element. A bimetallic switch including a snap disc for making and breaking contact with the electrical circuitry in response to the temperature of the heating element is also provided in the socket assembly. A dish-shaped contact member formed as part of the heater element of the plug assembly operates to place the heater element in circuit with the electrical circuitry of the socket assembly. The invention particularly provides an electrical connector device disposed between the electrical circuitry of the socket assembly and the dish-shaped contact member of the plug assembly which is connected with and disconnected from the electrical circuitry of the socket assembly by operation of the snap disc of the bimetallic switch. The electrical connector device is also disposed to cooperate with the dish-shaped contact member of the heater element when the plug assembly is in the connected position within the socket assembly to enable electrical heating of the heater element.
