Abstract

A battery terminal post connector in one embodiment includes a spring that urges a lower body towards an upper body when a battery terminal post is disposed therebetween. The urging of the spring causes an electrical connection between the connector and the post. A protective housing protects the connector and the battery terminal post. In another embodiment, a pair of springs are used to create a spring biased connection between lower and upper bodies and a battery terminal post. Thus, in both embodiments, a quick connect/quick disconnect function is achieved for each of the two connectors with respect to each associated battery terminal.

Claims

1. A battery terminal post connector that maintains an electrical connection between a battery cable and a terminal post of a battery, comprising:

an electrically conductive lower body that has a battery terminal post contact surface at its upper end;

spring means for urging said lower body towards said upper body when said post is disposed therebetween;

means for connecting said battery cable to said connector; and

a two piece, non-electrically conductive housing enclosing said upper body and said lower body and having socket insert protrusions connected to one piece of said two piece housing and corresponding sockets located in the other piece of said two piece housing to permit engagement with said socket insert protrusions to connect together both pieces of said two piece housing.

2. The connector of claim 1 wherein said means for connecting comprises:

a threaded hole in said lower body;

a cable insertion hole in said lower body that extends from a lower end thereof to intersect said threaded hole; and

a screw that is screwed into said threaded hole to fixedly contact are exposed, uninsulated end portion of said battery cable.

3. The connector of claim 1 wherein each said battery terminal post contact surface is arcuate.

4. The connector of claim 3 wherein each said battery terminal post contact surface has a radius of curvature that approximates a radius of curvature of said post.

5. The connector of claim 1 wherein said means for urging is a spring.

6. The connector of claim 5 wherein said spring is a coiled spring.

7. The connector of claim 6 wherein said lower body has at least one hole therethrough that extends from a lower end of said lower body to an upper end thereof, said hole having a portion with a reduced diameter and a portion with an enlarged diameter that form a shoulder that is in an abutting relationship with one end of said coiled spring, additionally comprising a rod with a shank that passes substantially axially through said coiled spring and said hole, a distal end of said rod being fixedly connected to said upper member, said rod having an enlarged proximal end that forms a shoulder that is in an abutting relationship with the other end of said spring.

8. The connector of claim 7 wherein said at least one hole being two holes provided through said lower body.

9. A battery terminal post connector that maintains an electrical connection between a battery cable and a terminal post of a battery, comprising:

an electrically conductive upper body that has a battery terminal post contact surface at its lower end;

an electrically conductive lower body that has a battery terminal post contact surface at its upper end;

means for urging said lower body towards said upper body when said post is disposed therebetween;

means for connecting said battery cable to said connector;

said means for urging is a spring, said spring is a coiled spring, and additionally comprising a retention frame wherein each body is disposed with an upper end of said upper body fixedly connected to an upper member of said retention frame, said coiled spring being disposed between a lower portion of said retention frame and said lower body;

said retention frame has at least one socket therein, additionally comprising;

a top frame having a socket insert protrusion that extends therefrom, said top frame having a lower member that is connected to said upper member of said retention frame, said top frame being rotatable to cause said socket insert to be inserted into said socket; and

a covering material that is connected to sides of said top frame.

10. The connector of claim 9 wherein said covering material is opaque.

11. The connector of claim 9 wherein said covering material is transparent.

12. The connector of claim 9 wherein said covering material is translucent.

13. The connector of claim 9 wherein said covering material is a plastic sheet cover.

14. The connector of claim 9 wherein said covering material is a glass sheet cover.

15. In the method of maintaining an electrical connection between a battery cable and a terminal post of a battery,

the steps of:

providing an electrically conductive upper body;

providing an electrically conductive lower body;

disposing a battery terminal post between said upper body and said lower body;

urging by means of at least one spring said lower body

towards said upper body; and

enclosing said upper body and said lower body with a two piece, non-electrically conductive housing having socket insert protrusions connected to one piece of said two piece housing and corresponding sockets located in the other piece of said two piece housing to permit engagement with said socket insert protrusions to connect together both pieces of said two piece housing.

16. In the method of claim 15 wherein said upper body has a contact surface at its lower end and said lower body has a contact surface at its upper end, said step of urging including spring biasing said surfaces into contact with said post.

17. In the method of claim 15, the additional steps of:

providing a battery cable insertion hole within said lower body; and

connecting said cable to said lower body within said insertion hole.

18. In the method of claim 17, including the step of using the battery cable to pull said lower body away from said upper body to provide a quick connect/quick disconnect between said upper body and said lower body and said terminal post.

19. In the method of claim 15 wherein two springs are provided for urging said lower body towards said upper body.
