Thermostatic means for interrupting the electric current through the socket assembly in the event the lighter plug is held in energizing position for a longer time than needed to bring the heating element of the plug to incandescence.，下面是Electric cigar lighters专利的具体信息内容。
1. In an electric cigar lighter, the combination comprising tubular metallic socket means being open at one end for reception of a removable plug and adapted for connection to one side of a protected DC electric circuit; an electrical insulator with a central opening therethrough being connected to and at least partially closing the other end of said socket means; metallic conductor means supported in the central opening and being adapted for connection to the other side of the protected circuit; a plug member insertable into said socket means and having an element to be heated substantially to incandescence by current from the protected DC electric circuit to which the lighter is connected; said metallic conductor means including a bimetallic current carrying latching contact member with a plurality of axially extending arms engaging and retaining said plug while said element thereof is being heated, and moving away from and releasing said plug for removal from said socket means when said element has been sufficiently heated for use; and said arms in response to excessive heat moving further from said plug and into contact with said socket means thereby creating a short causing interruption of the protected DC electric circuit and termination of current therefrom to said lighter.
2. In an electric cigar lighter, the combination in accordance with claim 1, and said socket means including a tubular metallic shell and a tubular metallic socket disposed within said shell; said shell And socket being connected to each other at the end of said socket means opposite from the open end thereof, and said arms of said bimetallic current carrying latching contact member moving into contact with said socket member in response to excessive heat thereby creating a short causing interruption of the protected circuit to which said lighter is connected
3. In an electric cigar lighter, the combination in accordance with claim 10, and said socket means including a tubular metallic shell and a tubular metallic socket disposed within said shell and connected thereto at the end of said socket means opposite from the open end thereof; said socket having a plurality of slots each located in register with a different one of said arms of said bimetallic current carrying contact member; means including said electrical insulator for preventing relative movement between said socket and conductor means to retain said arms and slots in register; and said arms moving through said slots and into contact with said shell in response to excessive heat thereby creating a short causing interruption of the protected circuit to which said lighter is connected.
4. In an electric cigar lighter, the combination in accordance with claim 1, and said socket means including a tubular metallic shell and a tubular metallic socket disposed within said shell and connected thereto at the end of said socket means opposite from the open end thereof; said socket having a plurality of slots each located in register with a different one of said arms of said bimetallic current carrying contact member; said shell being provided with a metallic sleeve encircling said slots and being spaced outwardly from said socket; means including said electrical insulator for preventing relative movement between said socket and conductor means to retain said arms and slots in register; and said arms moving through said slots and into contact with said sleeve in response to excessive heat thereby creating a short causing interruption of the protected circuit to which said lighter is connected.
