Description

Technical Field

[0001] The utility model belongs to the technical field of electronic components, and in particular relates to a wiring harness fuse. Background Art

[0002] A fuse is an overcurrent protector. It primarily consists of a housing, terminals, an element, and external fillers. When in use, the fuse is connected in series with the protected circuit. When the current in the protected circuit exceeds the specified value and a certain period of time has passed, due to overcurrent heating (current thermal effect), the heat inside the fuse accumulates, and the internal element reaches the melting point of the metal material. The element then melts, disconnecting the circuit and providing protection. It has an inverse time-delay characteristic: when the overload current is small, the melting time is long; when the overload current is large, the melting time is short. Therefore, within a certain overload current range, until the current returns to normal, the fuse will not blow and can continue to be used. A fuse primarily consists of a housing and a fuse tube, with the fuse tube being the key component controlling the melting characteristics.

[0003] When an existing fuse is damaged or needs to be replaced, the fuse housing needs to be disassembled and the wiring harness cannot be directly connected, which makes installation inconvenient. Moreover, when the fuse element burns out, the screws on the fuse housing need to be removed before a new fuse element can be replaced, which makes use inconvenient. Utility Model Content
