ABSTRACT:
A pair of substantially flat rectangular fusible links is constructed from progressive dies by partially cutting them from sheet metal stock as blanks, flanging edges on the parts and including the forming of triangular camming surfaces on such flanges, and then shearing the parts from the stock. Thereafter, the links are fluxed and soldered together and are held in interested complementary relation. It is characteristic of the links that there are no voids or discontinuities in the joined surfaces and into which flux will not flow; the interfacing triangular cam surfaces insure a clean breaking apart of the links once the eutectic temperature is reached because any longitudinal sliding movement of the links biases them laterally apart under the camming action to insure a complete break-away of the confronting soldered surfaces.
