Abstract

A battery booster cable clamp is disclosed in which one of the battery terminal clamping jaws is provided with a through slot for receiving and electrically engaging the head portion of a side-mount battery terminal bolt. The edges of the through slot are designed to clamp under an annular ledge formed in the battery bolt head, so that the opposing jaw engages the top surface of the terminal bolt to sandwich the battery terminal bolt head by gripping between the underside of the bolt annular ledge and the terminal bolt top surface.

Claims

1. An electrical connector for engaging a battery terminal, comprising;

(a) a first member having a handle and a first jaw for selectively engaging both a top-mount post-type battery terminal and a side-mount bolt-type battery terminal;

(b) a second member pivotally mounted to said first member, having a handle, a second jaw for engaging a top-mount post-type battery terminal, and a bolt-type battery terminal engaging surface having a closed through slot therein for receiving and engaging therein the head portion of a side-mount bolt-type battery terminal bolt, and for engaging a side-mount bolt-type battery terminal; and

(c) spring means for urging said first and second jaws toward each other.

2. An electrical connector as set forth in claim 1, wherein said closed through slot has opposed tapered sides for permitting said bolt-type battery terminal engaging surface to engage side-mount bolt-type battery terminal bolts having different head diameters.

3. An electrical connector as set forth in claim 1 or 2, wherein said first jaw comprises two engagement sections angled toward one another to expose respective corner edges thereof to define said first jaw.

4. An electrical connector as set forth in claim 1, wherein said bolt-type battery engaging surface includes an inner lip around said closed through slot for engaging a shouldered section of a side-mount bolt-type battery terminal bolt head.

5. An electrical connector as set forth in claim 1, 2, or 4, wherein said first jaw further includes a gripping section having a roughened surface thereon defining said jaw for engaging the top portion of a side-mount bolt-type battery terminal bolt head, and for engaging the side of a top-mount post-type battery terminal, to retain same in electrical contact therewith.

6. An electrical connector as set forth in claim 5, wherein said second jaw includes a gripping section having a roughened surface thereon defining said battery engaging surface for engaging the side of a top-mount post-type battery terminal to retain same in electrical contact therewith.

7. An electrical connector as set forth in claim 5, wherein said first jaw gripping section roughened surface comprises a series of teeth or serrations defining an essentially planer surface.

8. An electrical connector as set forth in claim 6, wherein said second jaw gripping section roughened surface comprises a series of teeth or serrations defining an essentially planer surface.
