Electric cigar lighter

摘要

The present disclosure relates to an electric cigar lighter for use, for example in vehicles, having a circuit breaker. The circuit breaker includes an elongated fuse member having a fuse and a tube for covering the fuse. The tube has a melting point slightly lower than that of the fuse. Therefore, when the fuse melts and separates in two parts upon overheating of a heating element carried by an igniting of the lighter, the separated ends of the fuse are wrapped by the separated ends of the tube. Thus, even if the separated ends of the fuse member contact some portions of the lighter placed adjacent to the fuse member or other members, a short circuit can be prevented.
