Title:
MANUFACTURE OF FOIL CONNECTING CONDUCTOR AND MANUFACTURE OF ALLOY TYPE THERMAL FUSE
Document Type and Number:
Japanese Patent JP3878732
Kind Code:
B
Abstract:
PROBLEM TO BE SOLVED: To provide a foil connecting conductor safely weldable to the plate electrode of a super-thin type alloy thermal fuse by welding and connecting a foil conductor to a shaft-like conductor having a width smaller than the width of the foil conductor, a thickness larger than the thickness of the foil conductor and a melting point lower than the foil conductor, and foiling the connections and the shaft-like conductor by compression.
SOLUTION: A substantially circular sectional shaft-like conductor 2 having a melting point lower than a copper foil 1 and a sectional area substantially equal to the sectional area of the copper foil 1 is welded to the copper foil 1. For the heating in welding, heating by contact of a heating block, hot air heating, or direct current-carrying heating is employed. The weld part and the shaft-like conductor are pressurized and molded into a foil having the same thickness as the copper foil. The foiling is performed by passing it to a rolling roll having a gap set to the thickness of the copper foil, compressing it by a press or the like. After the foiling, both the lateral sides are trimmed so as to be equal to the copper foil width, whereby a copper foil-low melting point metal foil connected body is provided.
