Abstract

A heavy duty, high efficiency jumper cable system designed to deliver 250 to 3,800 amps with minimal loss by transmitting current from a source through a cable/terminal connector through a heavy duty cable to a second cable/terminal connector and then to a discharge point. The cable/terminal connectors include an electrical harness that minimizes power loss by direct contact between the cable delivering current to the cable connector and a pair of electric contacts, each member of which is positioned in an end of a support. The system is uniquely, but not specifically adapted for use with electrical systems associated with diesel powered vehicles and equipment.

Claims

1. A cable/terminal connector comprising:

a. a frame structure comprised of a first frame unit and a second frame unit, said first frame unit and said second frame units being pivotally connected by a pin-like fastener that extends between said first frame unit and said second frame unit to form an axle and anchor for a spring positioned to exert pressure to allow said first frame unit and said second frame unit to jointly grasp and establish an electrical contact with an electric terminal, and further, said first frame unit and said second frame unit being adapted to allow an electrical harness to be positioned in channels in each of said first frame unit and said second frame unit; and

b. said electrical harness comprising a first electric contact element and a second electric contact element, said first electric contact element and said second electric contact element being connected by a cable attached to said first electric contact and said second electric contact by conductor connector means, a harness being in contact with one member of the pair of cables consisting of said negative cable and said positive cable by means of a conductor connection means connected by a fastener to said first support unit, and further said first electric contact and said second electric contact being positioned in a channel in each of said first and said second frame units.

2. The cable/terminal connector of claim 1 wherein said pin-like fastener is a rivet.

3. The cable/terminal connector means of claim 1 wherein said conductive connection means is a lug, and further wherein said first electrical contact and said second electrical contact are copper bars.

4. A single contact cable/terminal connector comprising:

a. a frame structure comprising of a first frame unit and a second frame unit, said first frame unit and said second frame unit being pivotally connected by a pin-like fastener that extends between said first frame unit and said second frame unit to form an axle and an anchor for a spring positioned to exert pressure to allow said first frame unit and said second frame unit to jointly grasp an electrical terminal, said first frame unit further being adapted with a channel to receive an electric contact;

b. said electric contact comprising a electrical contact element, said electrical contact element being connected by a conductor connection means to an end of one member of a pair of cable consisting of said positive cable and said negative cable, and said electrical contact element further being connected with said conductor connection means to said first support and positioned in the channel formed in said first support unit and held securely in place and in contact with said conductor connection means by a fastener;

c. said first frame is manufactured from conductive material, such as metal, and said second frame unit is manufactured from a sturdy, non-conductive material such as a plastic.
