Abstract

A battery terminal connector which is capable of reliably maintaining an electrical cable or harness in electrical contact with a battery, while having the added benefit of having an economical two-piece construction whose individual members are formed by separate stamping operations. The two-piece construction permits one member to be sized and structured to securely clamp the battery terminal post while the second member is sized and structured to securely crimp the electrical cable or cables. The battery terminal connector includes two separate circumferential bands, each of which circumscribes and clamps the battery terminal post. The circumferential bands define a circumferential slot therebetween which slightly extrudes the battery terminal post to increase the retention capability of the battery terminal connector.

Claims

1. An electrical connector for a battery post comprising:

a main terminal having one end, an opposite end and a frustoconical gripping portion interposed said one end and said opposite end, said frustoconical gripping portion having a substantially annular shape so as to define an axial opening therethrough, said axial opening having a central axis, said frustoconical gripping portion of said main terminal having a circumferentially extending slot; and

means for constricting said frustoconical gripping portion about said battery post, said constricting means being operable to cause a clamping action by said frustoconical gripping portion about said battery post;

whereby as said constricting means constricts said frustoconical gripping portion said circumferentially extending slot enables said frustoconical gripping portion to generate a clamping force.

2. The electrical connector of claim 1 wherein said circumferentially extending slot in said frustoconical gripping portion further defines a pair of circumferential strap members such that as said constricting means constricts said frustoconical gripping portion each of said circumferential strap members generates an individual clamping force.

3. The electrical connector of claim 2 wherein said axial opening has a substantially frustoconical shape such that one of said pair of circumferential strap members has a smaller internal diameter than the other of said pair of circumferential strap members.

4. The electrical connector of claim 1 wherein said one end of said main terminal comprises a first flange extending in a direction away from said frustoconical gripping portion;

and wherein said opposite end of said main terminal comprises a second flange extending in a direction away from said frustoconical gripping portion, said first and second flanges being adjacent each other.

5. The electrical connector of claim 4 wherein said first and second flanges extend from said frustoconical gripping portion in a predetermined spaced-apart relation so as to define a longitudinal slot therebetween.

6. The electrical connector of claim 5 wherein said means for constricting comprises:

an aperture through each said first and second flanges; and

fastener means disposed in each of said apertures;

whereby said fastener means is operable to draw said first and second flanges together so as to collapse said longitudinal slot and thereby constrict said frustoconical gripping portion.

7. The battery terminal of claim 5 further comprising a blade member attached to at least one of said first and second flanges.

8. The electrical connector of claim 1 wherein said one end of said main terminal further comprises a first flange having a substantially planar surface and further wherein said opposite end of said main terminal comprises a second flange having a substantially planar surface, each of said first and second flanges being adjacent to each other and extending in a direction away from said central axis of said axial opening of said frustoconical gripping portion.

9. The electrical connector of claim 8 wherein said means for constricting comprises:

an aperture through each said first and second flanges; and

fastener means disposed in each of said apertures;
