FUSE ASSEMBLY AND METHOD OF PRODUCING SAME

摘要

A miniature plug-in fuse assembly is provided in which a pair of conductive legs and a fuse link interconnecting them are integrally formed from fusible metal. An insulating casing wholly encloses the fuse link and a portion of the conductive legs, the casing having a hollow body with a cover which does not extend beyond the body in its longer dimension. The cover is secured to the body by a retaining arrangement employing the ends of the conductive legs, which also provides for the insertion of a test current to test the fuse link. Other ends of the legs extend through the body to provide plug-in members. The legs are fastened to the body by protruding lugs on the plug-in members and projecting stops on the portion of the legs in the casing. A method for making the fuse assembly of this invention involves a series of die stamping steps to form the legs and fuse link from a continuous strip of fusible metal and mounting the legs and fuse link in the casing.
