Abstract

A Full-Range fuse element assembly includes an insulative former having opposite first and second ends and electrically conducting connectors coupled to ends of the former. A plurality of fuse elements extend between the first connector and the second connector about the insulative former, and each of the fuse elements include a low current interrupting fuse element portion extending from the first connector and a high current limiting fuse element portion extending from the second connector. An insulative sleeve surrounds each of the low current interrupting fuse element portions, and each sleeve includes an end adjacent a respective one of the high current limiting fuse element portions. Each of the low current interrupting fuse element portions includes a weak spot located proximate the second end of a respective one of the sleeves.

Description

technical field

[0001] The present invention relates generally to a fuse element or link assembly, and more particularly to a fuse element assembly for a general purpose or full range fuse. Background technique

[0002] Fusible links are widely used as overcurrent protection devices to prevent damage to circuits. Fusible link terminals generally form an electrical connection between a power source and an electronic component or group of components distributed in an electrical circuit. One or more fusible links or elements, or fuse element assemblies, are connected between the fuse terminals so that when the current through the fuse exceeds a predetermined limit, the fusible element melts or one or more fuses are disconnected through the fuse. circuit to avoid damage to electronic components.

[0003] General purpose or full range high voltage current limiting fuses can safely interrupt higher fault circuits as lower fault circuits with equal efficiency. At least one type ...
