Abstract

A clamp for an electrical cable, such as a jumper cable utilized to jump start vehicles when the battery is dead. The clamp has a snag-free construction wherein the clamping arm to which the cable is attached extends through a slotted, downwardly projecting extension of the pivotally-attached cooperating arm such that the cable has a clear exit path of the cable. The cooperating arm also presents an angular aspect such that the gripping portion of the arm is closer to the other arm than in conventional clamps, and in the preferred embodiment the gripping portion of the arms are approximately parallel in the plane in which they lie.

Claims

1. A clamp for an electrical cable comprising:

a first clamping arm having a clamping end and a second end;

a second clamping arm having a clamping end and a second end, pivotally attached to the first clamping arm, said pivotal attachment being intermediate the ends of each of the clamping arms;

spring means disposed in the pivotal attachment for biasing the clamping ends of the clamping arms toward a closed position;

the second clamping arm having the cable attached to the second end of the second cable arm;

the second end of the first clamping arm having an extension, angularly disposed toward the second end of the second arm, said extension having an opening therein for receiving the second end of the second arm therethrough

whereby the cable attached to the clamp is precluded from becoming entangled with the arms of the clamp.

2. The clamp according to claim 1 wherein the respective ends of the first clamping arm form an obtuse angle of less than 180 degrees.

3. The clamp according to claim 2 wherein the respective ends of the first clamping arm form an obtuse angle of about 155 to about 165 degrees.

4. The clamp according to claim 3 wherein the respective ends of the first clamping arm form an obtuse angle of about 160 degrees.

5. The clamp according to claim 1 wherein the first clamping arm extension forms an obtuse angle with the second end of the clamping arm.

6. The clamp according to claim 5 wherein the obtuse angle between the clamping arm extension and the second end is from about 120 degrees to about 135 degrees.

7. The clamp according to claim 6 wherein the obtuse angle between the clamping arm extension and the second end is from about 125 degrees.

8. The clamp according to claim 1 wherein the second end of the second clamping arm extends through the opening in the extension of the second end of the first clamping arm.

9. The clamp according to claim 8 wherein the opening in the extension of the second end of the first clamping arm is a slot whereby when the clamping arms are pivoted such that the clamping ends are opened, the second end of the second clamping arm articulates freely within the opening.

10. The clamp according to claim 1 wherein the electrical cable is connected to the clamping end of the second clamping arm.

11. The clamp according to claim 1 wherein the second ends of the first and second clamping arms have griping surfaces disposed thereon.

12. The clamp according to claim 1 wherein the clamping end of the second arm has an electrically conductive gripping surface thereon.

13. The clamp according to claim 12 wherein the electrical cable is connected to the electrically conductive gripping surface.
