Abstract

The invention is a novel clamp for a car battery jumper. The main deficiency in the various clamps used in car battery jumpers is the very small contact surface area, which chokes off the electric current and makes the task of starting the vehicle very difficult. The new clamp disclosed herein features a longitudinal structure consisting of a spring and a metal disk. Upon gripping the terminal of a battery, the metal disk included in the clamp comes into contact with the top surface of the battery'"'"'s terminal, thus insuring a large contact surface area and hence a substantially better starting current.

Claims

1. A clamp for a vehicular battery, comprising:

a) at least two jaws for attaching said clamp to a terminal of said battery; and

b) a longitudinal conductive member comprising a straight spring that is placed at a location in between said jaws and electrically connected to said clamp, said longitudinal conductive member constructed and arranged to come into contact with said terminal when the clamp is attached to the terminal.

2. A clamp according to claim 1, wherein the longitudinal conductive member further comprises a metal disk.

3. A clamp according to claim 1, wherein the longitudinal conductive member further comprises a wire brush.

4. A clamp according to claim 1, wherein the longitudinal conductive member further comprises a compressible conductive material, said compressible conductive material is selected from the group consisting of conductive polymers and wire meshes.

5. A clamp according to claim 1, further comprising handles for forcing the jaws of the clamp away from each other.

6. A clamp according to claim 1, further comprising a special spring for forcing the jaws of the clamp toward each other.

7. A clamp according to claim 1, further comprising means for attaching an electrical cable or wire.

8. A clamp for a vehicular battery, comprising:

a) at least two jaws for attaching said clamp to a terminal of said battery; and

b) a compressible longitudinal conductive member that is placed at a location in between said jaws and electrically connected to said clamp, said compressible longitudinal conductive member is further attached to a planar metallic surface, wherein said planar metallic surface is constructed and arranged to come into contact with said terminal when the clamp is attached to the terminal.

9. A clamp according to claim 8, wherein the planar metallic surface is further attached to a wire brush.

10. A clamp according to claim 8, wherein the planar metallic surface is further attached to a compressible conductive material, said compressible conductive material is selected from the group consisting of conductive polymers and wire meshes.

11. A clamp according to claim 8, further comprising handles for forcing the jaws of the clamp away from each other.

12. A clamp according to claim 8, further comprising a special spring for forcing the jaws of the clamp toward each other.

13. A clamp according to claim 8, further comprising means for attaching an electrical cable or wire.
