Abstract

A crimp fuse constituting a separate unit independent of the electrical equipment with which it is to be used is disclosed, comprising a length of fuse wire material supported by an insulative rod onto each end of which is crimped a sleeve of e.g. conductive ribbon. An insulative covering, such as a shrunk-on piece of insulative tubing, insulates the wire and provides mechanical strength to the structure. One or both sleeves may be a double sleeve including a female terminal into which e.g. the stripped end of a line cord could be inserted for connection to the fuse. A pigtail may be provided at either or both ends to facilitate soldering.

Claims

1. A crimp fuse comprising:

a length of fuse wire material;

insulative rod means supporting said length of said fuse wire material;

first and second conductive sleeves crimped onto respective ends of said rod means in good electrical contact with said length of fuse wire material; and

an insulative coating covering said length of fuse wire material, said first conductive sleeve including a portion shaped for receiving an electrical conductor to be connected thereto by crimping.

2. The crimp fuse of claim 1, wherein said second conductive sleeve also includes a portion shaped for receiving an electrical conductor to be connected therewith by crimping.

3. The crimp fuse of claim 1, wherein said insulating coating is a shrunk-on plastic coating covering the entire length of said first and second conductive sleeves.

4. The crimp fuse of claim 3, further comprising a conductive pigtail connected said first conductive sleeve.

5. The fuse of claim 1, wherein the porion of the conductive sleeve for receiving an electrical conductor to be connected thereto and the original portion of the conductive sleeve crimped on the end of the fuse constituting a single continuous conductive metallic ribbon formed at one end into said sleeve member to be crimped onto an end of the fuse and the other end being at least partially formed into said shaped portion to be crimped on said conductor.
