A power fuse with zinc-aluminum terminals is provided. The power fuse includes a housing having a first end and a second end. Coupled to the housing at the first end is a first terminal assembly fabricated from a zinc-aluminum alloy, and coupled to the housing at the second end is a second terminal assembly also fabricated from the zinc-aluminum alloy. The first and second terminal assemblies include a copper plating entirely covering an exterior of the zinc-aluminum alloy. A fuse element assembly is positioned inside the housing and is electrically connected between the first terminal assembly and the second terminal assembly.

A fuse including a first housing part and a second housing part that are joined together to define a cavity, a fuse element disposed within the cavity, a first terminal extending from a first end of the fuse element and out of the housing, and a second terminal extending from a second end of the fuse element and out of the housing, the housing having a vent channel extending from an outer surface of the housing to the cavity for allowing vapor to escape from the cavity.

The invention provides a fuse that has a simple structure without having a flap included in a conventional fuse but can prevent a terminal of a different fuse from entering from an opening of an insulating housing. A fuse includes a pair of conductive terminals (10), a fuse element (30) including a fusing part (20) provided between the conductive terminals (10), and an insulating housing (40) covering the fusing part (20) and at least part of the conductive terminals (10) and having an open bottom end. The insulating housing (40) has an open end (50) provided, on an inner wall surface thereof, with a projection (60).

A self-powered wireless fuse switch is disclosed that is a plug-in replacement for a fuse found in the electrical system of vehicles. The self-powered wireless fuse adds remote-controlled switching capabilities for short and long-range control of power to subsystems of a vehicle electrical system. The wireless fuse switch includes a wireless control module having an internal power supply and an internal transceiver that receives commands from a remote control unit. A separate fuse module includes an outer housing and fuse blades that extend from the outer housing and interface with a fuse socket of the vehicle to selectively allow or interrupt power from the vehicle to the subsystem of the vehicle electrical system. The fuse module includes a fusible link, a relay controller and a relay in the outer housing. The fuse module receives power from and communicates with the wireless control module.

Method of manufacturing a high voltage power fuse having a dramatically reduced size facilitated by silicated filler material, a formed fuse element geometry, arc barrier materials and single piece terminal fabrications. The method includes: connecting a full-range fuse element assembly including first and second metal strip fuse elements defining a plurality of weak spots therein and being connected in parallel to one another, the first metal strip fuse element configured to uniquely respond to a short circuit current condition and the second metal strip fuse element configured to uniquely respond to an overload current condition and a set of arc barriers at selected locations to surround respective cross sectional portions are disclosed.

In one embodiment, a method of manufacturing a high voltage power fuse includes inserting a housing over a first assembly leg of an assembly frame, assembling a first terminal fabrication to the first assembly leg of the assembly frame, assembling a second terminal fabrication to a second assembly leg of the assembly frame, connecting a full-range fuse element assembly in a gap between the first terminal fabrication and the second terminal fabrication, sliding the housing over the connected full-range fuse element assembly, securing the housing in position to enclose the full-range fuse element assembly, and applying a silicated filler material to the assembled housing, full-range fuse element, and first and second terminals to establish a mechanical bond between the silicated filler material and the assembled housing, full-range fuse element, and first and second terminals.
