Cord type thermal fuse and sheet type thermal fuse

摘要

A cord type thermal fuse, comprising a fuse core produced by winding a conductor meltable at a predetermined temperature on an insulating core member continuous in the length direction, and an insulating cover covering the outer periphery of the fuse core, wherein the conductor can be cut by expanding the insulating core member at a predetermined temperature and/or by contracting the insulating cover at the predetermined temperature.
