Title:
ALLOY TYPE THERMAL FUSE AND MANUFACTURE OF ALLOY TYPE THERMAL FUSE
Document Type and Number:
Japanese Patent JP3878731
Kind Code:
B
Abstract:
PROBLEM TO BE SOLVED: To connect a plate electrode and a low melting point fusible alloy foil by welding and secure safety electrical contact between them in the manufacture of a very thin alloy type thermal fuse.
SOLUTION: In the manufacturing method of a thermal fuse in which a low melting point fusible alloy foil 4 is arranged between plate electrodes 2, 2 having larger thermal capacity than that of the metal foil 4, auxiliary pieces 5 having smaller thermal capacity than the thermal capacity of the plate electrode 2 are welded to both ends of the low melting point fusible alloy foil 4, then each auxiliary piece 5 is welded to each plate electrode 2.
