Abstract

Fuse assemblies are disclosed. In one implementation, a fuse assembly may be disposed that includes a first portion of the second portion. The first portion may be formed of a first metal. The second portion may be formed of a second metal different from the first metal. The second metal may be copper, and the copper may be tin plated or silver plated.

First claim

What is claimed is:

1. A fuse module, comprising:
a housing;
a fuse assembly coupled to the housing, the fuse assembly including:
a first portion formed of a first metal; and
a second portion disposed generally perpendicular to the first portion, the second portion formed of a second metal different from the first metal;
wherein the first portion and the second portion are contiguous portions of a single sheet of material having planar opposing surfaces.

2. The fuse module according to claim 1 , wherein the second metal is copper.

3. The fuse module according to claim 2 , wherein the copper of the second metal is tin-plated or silver-plated.

4. The fuse module according to claim 1 , wherein the second portion includes at least one fuse.

5. The fuse module according to claim 4 , wherein the second portion includes a plurality of fuses.

6. The fuse module according to claim 1 , wherein the second portion includes a plurality of fuses, and wherein at least a first of the plurality of fuses has an ampere rating that is lower than a second of the plurality of fuses.

7. The fuse module according to claim 1 , wherein the first and second portions are integrally formed to provide the fuse assembly.

8. The fuse module according to claim 1 , wherein the first portion includes an opening to facilitate coupling of the first portion to a terminal post of a battery.

9. The fuse module according to claim 1 , wherein the first metal is a non-copper conductive metal.

10. The fuse module according to claim 9 , wherein the non-copper conductive metal is aluminum.

11. An apparatus, comprising:
a fuse assembly including:
a first portion formed of a first metal; and
a second portion formed of a second metal different than the first metal, wherein the first portion facilitates coupling of the fuse assembly to a battery, and the second portion includes at least one fuse;
wherein the first portion and the second portion are contiguous portions of a single sheet of material having planar opposing surfaces.

12. The apparatus according to claim 11 , wherein the second metal is copper.

13. The apparatus according to claim 12 , wherein the copper of the second metal is tin plated or silver plated.

14. The apparatus according to claim 11 , further comprising a housing, the fuse assembly coupled to the housing.

15. The apparatus according to claim 11 , wherein the second portion includes a plurality of fuses.

16. The apparatus according to claim 11 , wherein the second portion includes a plurality of fuses, and wherein at least a first of the plurality of fuses has an ampere rating that is lower than a second of the plurality of fuses.

17. The apparatus according to claim 11 , wherein the first and second portions are integrally formed to provide the fuse assembly.

18. The apparatus according to claim 11 , wherein the first portion includes an opening to facilitate coupling of the first portion to a terminal post of the battery.

19. The apparatus according to claim 11 , wherein the first metal is non-copper conductive metal.

20. The apparatus according to claim 19 , wherein the non-copper conductive metal is aluminum.
