Title:
LARGE-CURRENT ALLOY TYPE TEMPERATURE FUSE
Document Type and Number:
WIPO Patent Application WO/2011/157230
Kind Code:
A1
Abstract:
A large-current alloy type temperature fuse for overheating protecting of a device with a large-current characteristic is disclosed. In the alloy type temperature fuse, a plurality of low melting point alloy wires (13) are welded and connected in parallel between two metal electrodes (11a, 11b) with favorable weldability. The metal electrodes are separated by a part (18) formed of an insulating material, and are provided with extension parts (11aa, 11bb) extending out of a shell (15), enabling a close thermal coupling between the large-current alloy type temperature fuse and the thermally protected device. Further, a fluxing agent material (14) is provided around each low melting point alloy wire, so that each low melting point alloy wire can be quickly and completely retracted to the electrodes after heated and melted, and thereby a large current is switched off safely.
