Abstract

A device and a method for connecting at least two electric terminals, particularly an electrode terminal and an electric measuring element, the two terminals being connected to each other by clinching.

Claims

1. A device for connecting at least two electric terminals, comprising:

an arrangement for connecting the two terminals to each other by clinching,

wherein a first of the terminals has at least one opening, into which a second of the terminals is at least partially deformed using clinching,

wherein the opening has a bevel provided at a rear end of the opening.

2. The device according to claim 1, wherein the two terminals are an electrode terminal and a measuring element.

3. The device according to claim 1, wherein the terminals are made of materials having different strengths.

4. The device according to claim 1, wherein the second terminal forms a back taper in a vicinity of the bevel, because of the clinching.

5. The device according to claim 1, wherein at least one of (a) the first terminal is made of a machining alloy and (b) the second terminal is made of a ductile material, including copper.

6. The device according to claim 1, wherein at least one of (a) the first terminal is an electrode terminal and (b) the second terminal is a measuring element.

7. The device according to claim 6, wherein the electrode terminal and the measuring element are connected at at least one location using clinching and at another location using a stud, insulated from each other by a sleeve.

8. The device according to claim 1, wherein at least one of (a) the first terminal is made of CuZn39Pb2 and (b) the second terminal is made of SE-Cu58.

9. The device according to claim 1, wherein the bevel is provided only at the rear end of the opening.
