Thermal fuse contacts material for a thermal fuse and using the same

摘要

PROBLEM TO BE SOLVED: To provide a contact material for temperature fuse which can prevent welding or adhesion to a lead completely without increasing the contact resistance value, and to provide a thermosensitive pellet temperature fuse using the same.;SOLUTION: A thermosensitive pellet temperature fuse utilizes a contact material 20 for temperature fuse including Cu or a base material 21 of a Cu alloy, a primary plating layer 22a of Ni covering the surface of the base material 21, a secondary plating layer 23a of Ag laminated on the surface of the primary plating layer 22a or an Ag alloy, and a compound thin film 24a of metal or semiconductor covering the upper part of the secondary plating layer 23a, where the compound thin film 24a consists of at least one selected from carbide, nitride, oxide and oxynitride.;COPYRIGHT: (C)2014,JPO&INPIT
