Abstract
Fuse element and bridge assemblies allow for construction of small fractional amp fuses with larger fuse element wires that are less prone to breakage in automated manufacturing processes.
Claims23
A fuse comprising:
- a nonconductive body having opposing first and second ends;
- first and second conductive terminal elements coupled to the body at the respective first and second ends;
- a nonconductive bridge element having opposed first and second ends, the nonconductive bridge element extending axially within the fuse body between the first and second conductive terminal elements;
- and
- at least one wire fuse element including a first end, a second end and a length therebetween, the length being wound around the nonconductive bridge element for at least one complete turn, the turn including a first linear segment and a second linear segment extending entirely from the first end to the second end of the nonconductive bridge element.

A fuse comprising:
- a nonconductive fuse body;
- first and second conductive terminal elements coupled to the fuse body;
- an elongated nonconductive bridge element having opposed first and second ends respectively positioned proximate the first and second conductive terminals;
- and
- at least one wire fuse element including a first end, a second end and a length therebetween, the length being wound around the nonconductive bridge element for a plurality of turns extending between the first and second ends, wherein the fuse has a current rating of about 1 A or less.
