ABSTRACT:
A miniature end capless fuse comprises a nonconductive sleeve with a fusible element extending through it and leads to the ends of the fuse wire. Each electric lead to the fuse wire includes a deformed region near its end, but located outside the sleeve, for being held by insulating material applied over the entire fuse. The deformed region may be an enlargement at the end which does not extend into the sleeve but is attached to the end of the sleeve. It may alternately be a notch formed in the lead. The sleeve ends are metallized, the fusible element ends are soldered to the ends of the sleeve and the leads near their deformed regions are soldered to the ends of the sleeve, forming the fuse. The entire fuse is covered with a strengthening covering, e.g., a molded covering, which securely holds the leads to the sleeve by their deformed regions, e.g. their enlargements or notches.
