CARTRIDGE HEATER WITH THERMAL FUSE

摘要

PROBLEM TO BE SOLVED: To provide a cartridge heater-having a thermal fuse where at generation of abnormal temperature at an heat radiating part, this abnormal temperature can be detected promptly and supply-current to the exothermic part can be stopped, and where situation can be prevented in which other parts and a heated device are damaged due to the temperature rise of the heat radiating part. SOLUTION: A thermal fuse 11 is mounted on one end of a heater lead wire 7 in the vicinity of the exothermic part 22, and a heat transfer means for extracting the heat of the heat radiating part and to transfer the heat to a side face of a thermal fuse 11 is installed.
