Abstract

A battery fuse assembly for a storage battery having a threaded post terminal is provided. The fuse assembly includes a bus bar having a planar surface and a first opening extending therethrough, at least one threaded terminal stud extending from the planar surface and distanced from the first opening, and a battery fuse coupled to the first surface over the second threaded post terminal.

Claims

1. A battery fuse assembly for a storage battery having a threaded post terminal, said fuse assembly comprising:

a bus bar comprising a planar surface and a first opening extending therethrough for receiving the threaded post terminal;

at least one threaded terminal stud extending from said planar surface and distanced from said first opening; and

a battery fuse coupled to said planar surface over said threaded terminal stud.

2. A battery fuse assembly in accordance with claim 1 further comprising an auxiliary power supply cable in electrical connection with said fuse.

3. A battery fuse assembly in accordance with claim 2 further comprising an insulative spacer element extending between said threaded terminal stud and said fuse.

4. A battery fuse assembly in accordance with claim 3 wherein said spacer element comprises a bearing contact surface, said bearing contact surface engaged to said auxiliary power supply cable.

5. A battery fuse assembly in accordance with claim 1 wherein said battery fuse is coupled to said first surface with a flange nut engaged to said threaded terminal post.

6. A battery fuse assembly in accordance with claim 1, said bus bar comprising a projection extending from said planar surface, said projection located adjacent said fuse.

7. A battery fuse assembly for a storage battery having a threaded post terminal, said fuse assembly comprising:

a bus bar comprising an end edge and a first surface extending from said end edge, said first surface comprising an opening therethrough, said opening distanced from said end edge, said opening dimensioned for receiving the threaded post terminal of the battery;

at least one threaded terminal stud extending from said first surface at a distance from said first opening; and

a battery fuse engaged to said first surface over said threaded terminal stud.

8. A battery fuse assembly in accordance with claim 7, said bus bar comprising a projection extending from said first surface, said projection located adjacent said fuse.

9. A battery fuse assembly in accordance with claim 7 further comprising an insulative spacer element extending between said threaded terminal stud and said fuse.

10. A battery fuse assembly in accordance with claim 9 further comprising an auxiliary power supply cable in electrical connection with said fuse, said cable contacting said spacer element.

11. A battery fuse assembly in accordance with claim 10 further comprising an flange nut engaged to said threaded terminal stud, thereby coupling said cable to said fuse.

12. A battery fuse assembly comprising:

a battery comprising a threaded terminal post;

a bus bar comprising a first opening and a second opening therethrough, said threaded terminal post extending through said first opening,

at least one threaded terminal stud extending through said second opening of said bus bar; and

a battery fuse engaged to said bus bar over said threaded terminal stud.

13. A battery fuse assembly in accordance with claim 12 further comprising an auxiliary power supply cable electrically connected to said fuse.

14. A battery fuse assembly in accordance with claim 13 further comprising an insulative spacer element inserted over said fuse terminal stud, said spacer element isolating said cable from said fuse terminal stud.

15. A battery fuse in accordance with claim 14 wherein said spacer element includes a collar portion and a neck portion, said neck portion isolating said fuse from said fuse terminal stud.

16. A battery fuse assembly comprising:

a battery comprising a threaded terminal post;

a starter cable in electrical connection with said terminal post,

a conductive bus bar having a first opening and a second opening therethrough, said threaded terminal post extending through said first opening;

a nut in threaded engagement with said battery terminal post, said nut coupling said bus bar and said starter cable to said battery terminal post;

a threaded terminal stud extending from said bus bar through said second opening;

a battery fuse comprising opposite bearing surfaces and an opening therebetween, said terminal stud extending through said opening in said fuse, one of said bearing surfaces contacting said bus bar;

an auxiliary power supply cable contacting the other of said bearing surfaces of said fuse;

an inulsative spacer element configured to isolate said auxiliary power supply cable and said fuse from said threaded terminal stud; and

a flange nut coupled to said threaded terminal stud with threaded engagement, said flange nut contacting said spacer element.

17. A battery fuse assembly in accordance with claim 16 wherein said threaded terminal stud comprises a shoulder stud.

18. A battery fuse assembly in accordance with claim 16 wherein said spacer element comprises a collar portion and a neck portion, a bore extending through said collar portion and said neck portion.

19. A battery fuse assembly in accordance with claim 16 wherein said collar portion comprises a bearing surface, said bearing surface in contact with said cable.

20. A battery fuse assembly in accordance with claim 16 wherein said bus bar comprises a third opening dimensioned for attachment of a second threaded terminal stud.
