Abstract
Abstract Disclosed is an improved fuse link assembly wherein a tensioned fusible element is secured at each end to a circuit conductor for connection to an external electrical circuit. The improvement includes an integral stamped crimp terminal which secures each end of the fusible element to a circuit conductor. The crimp member includes a serial succession of three discrete crimp portions, a first portion for receiving the fusible element, a second portion for receiving the circuit conductor, and a third portion for receiving a wire-like strain relief element disposed in parallel, cross the fusible element. The first crimp terminal (which receives the fusible element) is located between the second and third crimp portions. Each crimp portion has an internal diameter approximately equal to the diameter of the conductor received therein.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
158 words
In a fuse link assembly including a conductable fusible means having two ends, two circuit conductor means for connecting said fusible means to an external electrical circuit, and two terminal means each connecting a circuit conductor to a respective end of said fusible means, the improvement wherein a tensioned force is applied to the fuse link assembly comprising: two spaced-apart, integrally stamped conductive crimp members defining said two terminal means, said crimp members biased away from each other by the tension force; an electrically conductive strain relief means connected between said crimp members to reduce tension on said fusible means; and each crimp member including a first crimp section for receiving an end of said fusible means such that said fusible means is mechanically and electrically connected between said crimp members, a second discrete crimp section for receiving one of the circuit conductor means, and a third discrete integrally formed crimp section for securing said strain relief means.
Claim 2
Dependent Claim
158 words
In a fuse link assembly including a conductable fusible means having two ends, two circuit conductor means for connecting said fusible means to an external electrical circuit, and two terminal means each connecting a circuit conductor to a respective end of said fusible means, the improvement wherein a tensioned force is applied to the fuse link assembly comprising: two spaced-apart, integrally stamped conductive crimp members defining said two terminal means, said crimp members biased away from each other by the tension force; an electrically conductive strain relief means connected between said crimp members to reduce tension on said fusible means; and each crimp member including a first crimp section for receiving an end of said fusible means such that said fusible means is mechanically and electrically connected between said crimp members, a second discrete crimp section for receiving one of the circuit conductor means, and a third discrete integrally formed crimp section for securing said strain relief means.
Claim 3
Dependent Claim
27 words
The arrangement of claim 1 wherein said first, second, and third crimp sections are aligned in a serial succession of stamped portions formed in a unitary blank.
Claim 4
Dependent Claim
18 words
The arrangement of claim 2 wherein said first, second, and third crimp sections each include co-planar bight portions.
Claim 5
Dependent Claim
20 words
The arrangement of claim 3 wherein said first crimp section is disposed between said second and said third crimp sections.
Claim 6
Dependent Claim
34 words
The arrangement of claim 4 wherein said strain relief means comprises an elongated conductor generally coextensive with and parallel to said fusible member and having a free end received in said third crimp section.
Claim 7
Dependent Claim
37 words
The arrangement of claim 5 wherein portions of the free end of said strain relief means is disposed between said fusible element and said bight of said third crimp section so as to be laterally adjacent thereto.
Claim 8
Dependent Claim
19 words
The arrangement of claim 6 wherein at least one of said circuit conductor means comprises a flexible conductive cable.
Claim 9
Dependent Claim
20 words
The arrangement of claim 7 wherein the other of said circuit conductor means comprises a relatively inflexible conductive stud member.
Claim 10
Dependent Claim
18 words
The arrangement of claim 5 wherein said strain relief means has a higher resistivity than said fusible member.
Claim 11
Dependent Claim
30 words
The arrangement of claim 1 wherein said two crimp members are substantially identical to each other and said fuse link assembly is fully assembled by crimping said six crimp sections.
