A high voltage power distributor comprises an insulated high voltage power cable, a fuse mechanically connected to a fuse holder and a busbar that is electrically connected between the cable and the fuse. The fuse, the fuse holder, the busbar and the cable are accommodated in a housing.

Surface mount electrical fuse with a support bridge

An improved surface mount electrical fuse including a first fuse terminal; a second fuse terminal spaced apart from the first fuse terminal; and a fuse element formed from a conductive material, the fuse element having a support bridge for supporting the fuse element, the fuse element electrically connecting the first fuse terminal and the second fuse terminal.

Fuse with stone sand matrix reinforcement

An electrical fuse includes a housing, first and second terminal assemblies coupled to the housing, and at least one fuse element assembly extending internally in the housing and coupled between the first and second terminal assemblies. A filler surrounds the at least one fuse element assembly, and the filler includes sodium silicate sand and at least one reinforcing structure suspended within the filler.

Shock resistant mounting structures for fuze systems

Shock resistant mounting structures for fuze systems. The shock resistant mounting structures may comprise: a shock resistant fuze cap and a shock resistant collar. The shock resistant fuze cap may comprise a circular cap housing and a plurality of cripple studs disposed within the circular cap housing. The circular cap housing may be adapted to engage an upper portion of a fuze and may be adapted to snugly fit within a fuze well. The shock resistant collar may comprise a ring-shaped housing and one or more cripple studs radially disposed within the ring-shaped housing. The ring-shaped housing may have a center opening adapted to engage a fuze body. When installed, the shock resistant fuze cap and shock resistant collar may be disposed within the fuze well and may minimize, prevent, or divert shock loading energy from entering a fuze.

Fabrication of printed fuse

A power fuse for protecting an electrical load subject to transient load current cycling events in a direct current electrical power system is provided. The power fuse includes at least one fuse element assembly that includes an elongated planar substrate, a plurality of fusible weak spots, and a conductor. The weak spots are formed on the substrate and are longitudinally spaced from one another on the substrate. The conductor is separately provided from the substrate and the weak spots. The conductor includes a solid elongated strip of metal having no stamped weak spot openings therein and therefore avoiding thermal-mechanical fatigue strain in the conductor when subjected to the transient load current cycling events. The solid elongated strip of metal includes coplanar connector sections that are mounted to respective ones of the weak spots and obliquely extending sections bent out of plane of the connector sections to extend above the substrate.
