Problems solved by technology

If the fusible link is not properly connected to the electrical conductor, the fuse may be damaged or inoperable, which can lead to failure during an electrical event and damage sensitive electrical components
Additionally, a fuse may comprise several separate components that require welding or brazing for assembly, thereby complicating and increasing the cost of the fuse's assembly / disassembly, as well as introducing additional potential failure points for the fuse

Abstract

The invention provides a fuse and a method of forming fuses. Exemplary embodiments of the present disclosure of a fuse may include a fuse body having a first portion and a second portion. The first and second portions may be configured to mate together thereby forming an internal cavity. A first inner termination and a second inner termination may be at least partially attachable to the first andsecond portions of the fuse body at respective first and second ends. A fusible element may be disposed in the cavity of the fuse body and extendable from the first inner termination at the first endof the fuse body to the second inner termination at the second end of the fuse body. The fusible element may be attachable to the first inner termination at a first connection and the second inner termination at a second connection. The first and second connections may be inspectable when the fuse is in an assembled state.

Description

[0001] Cross references to related applications [0002] This application claims the benefit of U.S. Provisional Patent Application 62 / 794,730 filed on January 21, 2019, which is incorporated herein by reference in its entirety. Technical field [0003] The embodiments of the present disclosure generally relate to the field of fuses, and more specifically, to fuses that are configured to facilitate visual inspection of fusible elements. Background technique [0004] Fuse bodies for different applications are generally constructed such that the fusible element is enclosed in the fuse body during assembly and is not visible for inspection of the connection point with the electrical conductor. If the fusible wire is not properly connected to the electrical conductor, the fuse may be damaged or inoperable, which can cause failure during electrical events and damage sensitive electrical components. In addition, the fuse may include several separate components that need to be welded or b...
