Abstract: A fuse end cap for providing an electrical connection between a fuse and an electrical conductor. The fuse end cap may include a mounting cuff defining a first cavity that is adapted to receive a fuse body. The mounting cuff may be configured to be mounted to the fuse body by friction fit, for example. The fuse end cap may further include a terminal defining a second cavity adapted to receive a conductor. The terminal may be configured to be crimped about the conductor to retain the conductor within the second cavity.

Abstract: Disclosed is an improved fuse link assembly wherein a tensioned fusible element is secured at each end to a circuit conductor for connection to an external electrical circuit. The improvement includes an integral stamped crimp terminal which secures each end of the fusible element to a circuit conductor. The crimp member includes a serial succession of three discrete crimp portions, a first portion for receiving the fusible element, a second portion for receiving the circuit conductor, and a third portion for receiving a wire-like strain relief element disposed in parallel, cross the fusible element. The first crimp terminal (which receives the fusible element) is located between the second and third crimp portions. Each crimp portion has an internal diameter approximately equal to the diameter of the conductor received therein.
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.
