Abstract
A fuse includes an electrical assembly and a fuse tube assembly. The electrical assembly has two electrical contacts accessible from the exterior of the fuse and a fuse element in contact with the two electrical contacts. The fuse tube assembly includes a support structure surrounding at least a portion of the electrical assembly and a reinforcing structure formed over the support structure and in contact with at least a portion of the electrical assembly. The reinforcing structure is made of a fiber matrix pre-impregnated with a resin.
Claims25
A fuse comprising:
- an electrical assembly comprising two electrical contacts accessible from an exterior of a fuse and a fuse element in contact with the two electrical contacts;
- and
- a fuse tube assembly comprising a pre-formed tubular support structure surrounding at least a portion of the electrical assembly and a reinforcing structure formed over the pre-formed tubular support structure after the pre-formed tubular support structure is formed, the reinforcing structure being in contact with at least a portion of the electrical assembly, wherein the reinforcing structure comprises a fiber matrix pre-impregnated with a resin.
A fuse comprising:
- an electrical assembly comprising two electrical contacts accessible from an exterior of the fuse and a fuse element in contact with the two electrical contacts;
- and
- a fuse tube assembly comprising a pre-formed tubular support structure surrounding at least a portion of the electrical assembly and a reinforcing structure formed over the pre-formed tubular support structure after the pre-formed tubular support structure is formed;
- wherein the reinforcing structure comprises a resin composition of discontinuous fibers arbitrarily dispersed in an epoxy.
