ABSTRACT:
A fuse link and a method of manufacturing same are disclosed. The fuse link comprises a fusible element extending between an upper terminal and a lower terminal. The lower terminal includes a compressed segment of a multi-strand cable to which the fusible element is attached. In practicing the method of the present invention, a segment of the multi-strand cable is first radially compressed, as by cold-forming, to produce a longitudinal receiving region or pocket indentation for receiving an end of the fusible element. Thereafter, an end of the fusible element is placed into the receiving region. The region is then further compressed and collapsed to secure the fusible element therein by crimping a compressible sleeve previously placed around the fusible element and the cable-segment.
