Abstract

An electrical device, in particular a device for determining electrical variables (battery sensor), is provided which includes a connecting region between the part of the device which determines electrical variables and an attachment point. The connecting region has an essentially central axis. The device has a conductive interface between two conductor sections, the interface being offset from the central axis.

Claims

1. An electrical device for determining electrical variables, comprising:

a connecting region between a part of the device which determines electrical variables and an attachment point, the connecting region having a substantially central axis and having a conductive interface between first and second conductor sections, the interface being offset from the central axis.

2. The electrical device according to claim 1, further comprising an additional connecting region, on another side of the central axis viewed from the interface, which connects the second conductor section to the attachment point.

3. The electrical device according to claim 2, wherein the second conductor section is connected to the attachment point via at least one form fit.

4. The electrical device according to claim 3, wherein the form fit includes a molded part which encloses both conductor sections.

5. The electrical device according to claim 4, wherein the molded part has a shape of two closed interconnected rings.

6. The electrical device according to claim 5, wherein a connection point at which the two rings are joined insulates both conductor sections from each other.

7. The electrical device according to claim 4, wherein the molded part is a housing section.

8. The electrical device according to claim 1, wherein the two conductor sections are integrally joined to each other at the interface.

9. The electrical device according to claim 1, wherein the attachment point holds the device stationary.

10. The electrical device according to claim 1, wherein the attachment point is adapted to hold the device on a customary battery terminal of a battery in a motor vehicle.
