Abstract

The battery terminal clamp is capable of being received by batteries having either top post or side terminals. A connector is slidably carried between the clamp portions of a battery clamp. The connector includes a pair of longitudinal arms and interconnecting web providing a handle. The connector is selectively extensible beyond the connector jaws for engaging a battery side terminal. When connected to a battery side terminal the jaws engage the connector for applying pressure to the connector arms for assuring a good electrical and mechanical connection to the battery side terminal.

Claims

1. An improved battery clamp for use with top post and side terminal batteries in which a pair of opposed clamp portions are hingedly connected, and a biasing means operatively engages the opposed clamp portions and tends to bias the clamp to a closed position wherein the improvement comprises:

a side terminal connector carried by the clamp and selectively extensible beyond the clamp portions with the clamp portions selectively engaging the connector under the force of the biasing means for providing a battery side terminal engagement force to the connector.

2. An improved battery terminal clamp as defined in claim 1, in which:

the clamp portions each include a jaw and the jaws selectively engage the connector.

3. An improved battery terminal clamp as defined in claim 2, in which:

a pivot pin hingedly connects the clamp portions, and the connector is mounted about the pivot pin.

4. An improved battery terminal clamp as defined in claim 3, in which:

the connector includes a longitudinal body having a handle end and a terminal receiving end, the body is provided with a longitudinal slot extending from the vicinity of the handle to the terminal receiving end.

5. An improved battery terminal clamp as defined in claim 4, in which:

the clamp portions include handle portions which are selectively engageable with the connector handle end for holding the connector.

6. An improved battery terminal clamp as defined in claim 5, in which:

the connector handle end includes an electrically insulating cover material.

7. An improved battery terminal clamp as defined in claim 4, in which:

the terminal receiving end includes a first pair of opposed notches and a longitudinally spaced second pair of opposed notches formed in the longitudinal slot, the connector being selectably engageable with a battery side terminal at said first and second opposed notches.

8. An improved battery terminal clamp as defined in claim 1, in which:

the side terminal connector includes a pair of opposed longitudinal arms having first and second ends, a web interconnecting the arms at the first ends, and the arms have margins defining a slot therebetween extending from the web to the second ends.

9. An improved battery terminal clamp as defined in claim 8, in which:

the arms have a midpoint between their first and second ends, and

the opposed clamp portions selectively engage the arms at a point substantially between the midpoint and the second end of each arm for providing the battery terminal engagement force to the connector.

10. An improved battery terminal clamp as defined in claim 8, in which:

the arm margins define stop member providing a reduced slot width at a point longitudinally spaced from the web.

11. An improved battery terminal clamp as defined in claim 10, in which:

a pivot pin hingedly connects the clamp portions and the connector is mounted to the clamp with the pivot pin within the slot between the web and the stop members.

12. An improved battery terminal clamp as defined in claim 11, in which:

the pivot pin has a thickness which is greater than said reduced slot width whereby extension of the connector beyond the clamp portions is limited by engagement of the pivot pin with the web and retraction of the connector within the clamp portion is limited by engagement of the pivot pin with the stop members.

13. An improved battery terminal clamp as defined in claim 10, in which:

the margins define first opposed cam members at the second ends of the arms, and

the margins are provided with battery side terminal engaging opposed first notches adjacent to the first cam members.

14. An improved battery terminal clamp as defined in claim 13, in which:

the margins define second opposed cam members adjacent to the first notches, and the margins are provided with battery side terminal engaging opposed second notches adjacent to the second cam members.

15. An improved battery terminal clamp as defined in claim 14, in which:

the stop members are located adjacent to the second notches.

16. An improved battery terminal clamp as defined in claim 8, in which:

retaining means resiliently engages the connector for holding the connector adjacent to one of the clamp portions with the connector selectively positioned within the clamp portions.

17. An improved battery terminal clamp as defined in claim 16, in which:

the retaining means comprising a resilient ring.

18. An improved battery terminal clamp as defined in claim 17, in which:

the resilient ring engages the connector at one of the arm margins within the slot.

19. An improved battery terminal clamp as defined in claim 18, in which:

the resilient ring is an O-ring positioned about said one of the clamp portions.
