Abstract

A battery terminal clamp for attachment to batteries having either top or side mounted battery terminal posts includes a housing, a dual-clamp connector disposed within the housing, and a clamp selector operatively coupled to the dual-clamp connector. The dual-clamp connector includes first and second clamps positioned at opposite ends of the housing, and a current exchange terminal in between. The first clamp is configured for engaging a first type of battery terminal post, and the second clamp is configured for engaging a second type of battery terminal post. The clamp selector can be selectively set to either a first or second position. The first position exposes only the first clamp, while the second position exposes only the second clamp.

Claims

1. A battery terminal clamp comprising:

a housing including at least one opening therein;

a dual-clamp connector disposed within said housing, said dual-clamp connector including;

a first clamp configured for engaging a first type battery terminal post,

a second clamp configured for engaging a second type battery terminal post, and

a current exchange terminal for connecting a cable to said dual-clamp connector; and

a clamp selector operatively coupled to said dual-clamp connector for selectively exposing either said first clamp or said second clamp through one of said at least one opening when the selector is placed in a first position or a second position, respectively;

wherein said exposed clamp can engage the first or second type battery terminal post.

2. The battery terminal clamp of claim 1, wherein said housing has a generally rectangular configuration of a length greater than its width, and wherein a side corresponding to the width of said housing contains one of said openings.

3. The battery terminal clamp of claim 1, wherein said housing is formed from a thermoplastic material.

4. The battery terminal clamp of claim 1, wherein said first clamp includes a first pair of jaws containing first inner curved surfaces cooperatively positioned and sized for receiving said first type battery terminal post.

5. The battery terminal clamp of claim 1, wherein said second clamp includes a second pair of jaws containing second inner curved surfaces cooperatively positioned and sized for receiving said second type battery terminal post.

6. The battery terminal clamp of claim 1, wherein said first clamp is positioned at a first end of said dual-clamp connector and said second clamp is positioned at second opposite end of said dual-clamp connector.

7. The battery terminal clamp of claim 1, wherein said current exchange terminal is positioned between said first and second ends of said dual-clamp connector.

8. The battery terminal clamp of claim 1, wherein said housing includes a third opening along the housing length, and said current exchange terminal comprises a projecting member extending from said dual-clamp connector and through said third opening.

9. The battery terminal clamp of claim 1, wherein said housing includes a fourth opening along the housing length, and said clamp selector includes a second projecting member extending from said dual-clamp connector and through said fourth opening.

10. The battery terminal clamp of claim 1, wherein said first type battery terminal post is a top mounted battery terminal post, and said second type battery post is a side mounted battery terminal post.

11. The battery terminal clamp of claim 1, wherein said dual-clamp connector is formed from a conductive material.

12. The battery terminal clamp of claim 11, wherein said conductive material comprises copper.

13. The battery terminal clamp of claim 1, further comprising a locking mechanism for locking said clamp selector in said first and second positions.

14. The battery terminal clamp of claim 13, wherein said dual-clamp connector includes an aperture, and said locking mechanism includes at least one latch for engaging said aperture and locking said dual-clamp connector in either said first or second position.

15. The battery terminal clamp of claim 13, wherein said dual-clamp connector includes an aperture, and said locking mechanism includes at least one connector capable of being inserted through a corresponding aperture in said housing and into the aperture in said dual-clamp connector for locking said dual-clamp connector in either said first or second position.

16. The battery terminal clamp of claim 15, wherein said connector is a threaded fastener.

17. The battery terminal clamp of claim 15, wherein said connector is a spring loaded rivet.

18. A jumper cable set comprising:

a pair of electrically conductive cables having a prescribed current conducting capacity, each said electrically conductive cables having a first end and a second end; and

a battery terminal clamp attachable to each end of said electrically conductive cables, said battery terminal clamp including;

a housing including at least two openings therein;

a dual-clamp connector disposed within said housing, said dual-clamp connector including;

a first clamp positioned at a first end of the connector and configured for engaging a first type battery terminal post,

a second clamp positioned at a second, opposite end of the connector and configured for engaging a second type battery terminal post, and

a current exchange terminal positioned between said first and second ends of said dual-clamp connector for connecting said battery terminal clamp to a corresponding end of said electrically conductive cables; and

a clamp selector operatively coupled to said dual-clamp connector for selectively exposing either said first clamp or said second clamp through one of said at least two openings when the selector is placed in a first position or a second position, respectively;

said exposed clamp being connectable to either the first or second type battery terminal post.

19. An arrangement for transferring charge to a discharged battery, comprising:

a charging unit;

a jumper cable set having a first pair of ends attachable to said charging unit, and a second pair of ends attachable to the discharged battery; and

a battery terminal clamp attached to each end of said jumper cable set, said battery terminal clamp including;

a housing including at least two openings therein;

a dual-clamp connector disposed within said housing, said dual-clamp connector including;

a first clamp positioned at a first end of the connector and configured for engaging a first type battery terminal post,

a second clamp positioned at a second, opposite end of the connector and configured for engaging a second type battery terminal post, and

a current exchange terminal positioned between said first and second ends of said dual-clamp connector for connecting said battery terminal clamp to a corresponding end of said electrically conductive cables; and

a clamp selector operatively coupled to said dual-clamp connector for selectively exposing either said first clamp or said second clamp through one of said at least two openings when placed in a first position or a second position, respectively;

said exposed clamp being connectable to the first or second type battery terminal post.

20. The arrangement of claim 19, wherein said charging unit is a battery charger.
