Abstract

A dual conductive electrical jumper clamp system has two jumper clamps, each jumper clamp having upper and lower clamp frames and an electrical conductive contact plate positioned within each frame. An electrical conductive sleeve is positioned between the contact plates. In this manner, electricity is transmitted from an electric power source to only one of the contact plates, then solely to the other contact plate via the conductive sleeve, and ultimately to electrical terminal attaching jaw members at the ends of the contact plates.

Claims

1. A jumper clamp for transmitting electricity from an electrical. power source to an electrical terminal, said jumper clamp comprising:

an upper clamp frame;

first electricity conductor means positioned within the upper clamp frame for receiving electricity from an electrical power source and for transmitting electricity to an electrical terminal;

a lower clamp frame;

second electricity conductor means positioned within the lower clamp frame for receiving electricity solely from the first electricity conductor means and for transmitting this electricity to the electrical terminal; and

an electrical conductive sleeve means for transmitting electricity between the first electricity conductor means and the second electricity conductor means, whereby upon receiving electricity from the electrical power source, the first electricity conductor means transmits electricity to the second electricity conductor means via the sleeve means.

2. The jumper clamp as in claim 1 wherein the second electricity conductor means comprises an electrical conductive contact plate having an electrical terminal attaching jaw member.

3. The jumper clamp as in claim 1 further comprising an electrical conductive wire extending from the electrical power source to and into the first electricity conductor means for transmitting electricity to said first electricity conductor means.

4. The jumper clamp as in claim 1 further comprising spring means for biasing the upper clamp frame and the lower clamp frame in a closed position, whereby application of pressure on the upper clamp frame and the lower clamp frame positions the frames in an open position, in spaced relation to each other.

5. The jumper clamp as in claim 1 wherein the first electricity conductor means comprises an electrical conductive contact plate having an electrical terminal attaching jaw member.

6. The jumper clamp as in claim 5 wherein the second electricity conductor means comprises an electrical conductive contact plate having an electrical terminal attached jaw member.

7. The jumper clamp as in claim 5 further comprising an electrical conductive wire extending from the electrical power source to and into the contact plate.

8. The jumper clamp as in claim 1 further comprising an electrical conductive wire extending from the electrical power source to and into the first electricity conductor means for transmitting electricity to said first electricity conductor means.

9. A jumper clamp for transmitting electricity from an electrical power source to an electrical terminal, said jumper clamp comprising:

an upper clamp frame;

an electrical conductive contact plate positioned within the upper clamp frame, said contact plate having an electrical terminal attaching jaw member;

a lower clamp frame; and

a second electrical conductive contact plate positioned within the lower clamp frame, said second contact plate having an electrical terminal attaching jaw member; and

an electrical conductive sleeve positioned between the contact plates, whereby electricity is transmitted only to the contact plate within the upper clamp frame and then solely to the second contact plate within the to lower clamp frame via the conductive sleeve.

10. The jumper clamp as in claim 9 further comprising an electrical conductive wire extending from the electrical power source to and into the contact plate within the upper clamp frame for transmitting electricity to said contact plate.

11. The jumper clamp as in claim 9 further comprising spring means for biasing the upper clamp frame and the lower clamp frame in a closed position, whereby application of pressure on the upper clamp frame and the lower clamp frame maintains the frames in an open position, in spaced relation to each other.

12. The jumper clamp as in claim 11 wherein the jaw member of the second contact plate overlays and is in contact with the jaw member of the first contact plate when the upper clamp frame and lower clamp frame are in the closed position, and the second jaw member is located above and in spaced relation to the first jaw member when the upper clamp frame and the lower clamp frame are in the open position.

13. A jumper clamp system for transmitting electricity from an electrical power source to an electrical terminal, said jumper clamp system comprising:

a first clamp comprising an upper clamp frame having an electrical conductive contact plate positioned within the frame, said contact plate having an electrical terminal attaching jaw member, the clamp further comprising a lower clamp frame having an electrical conductive contact plate positioned within the frame, said contact plate having an electrical terminal attaching jaw member; and

a second clamp comprising an upper clamp frame, an electrical conductive contact plate positioned within the upper clamp frame, said contact plate having an electrical terminal attaching jaw member, the second clamp further comprising a lower clamp frame, said lower clamp frame having an electrical conductive second contact plate positioned within the lower clamp frame, said contact plate having an electrical terminal attaching jaw member; and

an electrical conductive sleeve positioned between the contact plates within the upper clamp frames of the first and second clamps, whereby electricity is transmitted only to the contact plate within the upper clamp frame of the first clamp and then solely to the contact plate within the upper clamp frame of the second clamp via the conductive sleeve.

14. The jumper clamp system as in claim 13 further comprising an electrical conductive wire extending from the electrical power source to and into the contact plates within the upper clamp frames of both the first and second clamps for transmitting electricity to said contact plates.

15. The jumper clamp system as in claim 13 further comprising spring means for biasing the upper clamp frames and the lower clamp frames of the first and second clamps in closed positions, whereby application of pressure on the upper clamp frames and the lower clamp frames maintains the frames in open positions, in spaced relation to each other.

16. The jumper clamp system as in claim 15 wherein the jaw members of the contact plates of the lower clamp frames of the first and second clamps overlay and are in contact with the jaw members of the contact plates of the upper clamp frames of the first and second clamps when the upper clamp frames and lower clamp frames are in the closed position, and the jaw members of the contact plates of the upper clamp frames of the first and second clamps are located above and in spaced relation to the jaw members of the contact plates of the lower clamp frames when the upper clamp frames and the lower clamp frames are in the open position.
