Abstract

According to the invention, an at least partially insulated strand of a battery terminal connection cable is either welded to a contact piece using ultrasound or is welded with a contact piece. As a result, the contact piece can be fastened onto the battery terminal using a conventional screw without worrying about the screw becoming loose. The battery terminal connection cable can be produced in an easy and at least partially automated manner using a device which comprises a sonotrode, a strand feed device, a contact piece feed device, and a pressure cylinder.

Claims

1. A battery terminal connecting cable comprising:

a) a strand comprising a plurality of fine wires, and having a further section formed when said plurality of fine wires are pressed together and, wherein said plurality of fine wires are welded together in said further section;

b) an insulator disposed over a central region of said strand adjacent to said further section;

c) a flat contact piece coupled to only one side of said further section, wherein said further section is disposed at an end of said strand wherein said further section is formed on said end of said strand by pressing said plurality of fine wires together; and

said further section is welded to said contact piece.

2. The battery terminal cable as in claim 1, wherein said further section is made from copper.

3. The battery terminal cable as in claim 1, wherein said further section extends longitudinally at an angle to a longitudinal axis of the cable.

4. A battery terminal connecting cable consisting of:

a) a strand cable comprising a plurality of fine wires, and having a further section formed when said plurality of fine wires are pressed together and, wherein said plurality of fine wires are welded together in said further section;

b) an insulator disposed over a central region of said strand adjacent to said further section;

c) an additional insulator disposed over said further section;

d) a flat contact piece coupled to only one side of said further section, wherein said further section is disposed at an end of said strand wherein said further section is formed on said end of said strand by pressing said plurality of fine wires together, and said further section is welded to said contact piece.

5. A battery pole connection cable comprising:

a) a stranded cable formed from a plurality of fine wires, wherein the stranded cable is at least partially insulated; and

b) a contact piece for an attachment of said battery pole connecting cable to a battery pole and as a predefined end of said battery pole connecting cable wherein said contact piece is a flat plate having a screw hole, wherein said plurality of fine wires are welded on said contact piece.
