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:

an electronic circuit adapted to determine the electrical variables;

a first conductor section;

a second conductor section mechanically coupled to the first conductor section via a single conductive interface that provides an electrical connection between the first conductor section and the circuit;

an attachment point adapted to mechanically stabilize the device by attaching the device to an external object; and

a single, solid connecting region in which the interface is located, wherein the single, solid connecting region;

connects at a first end to the attachment point,

connects at a second end opposite the first end to a housing of the device,

extends between the circuit and the attachment point, and

includes a substantially central axis passing through a center point thereof, the central axis further passing through a center point of the attachment point, wherein the interface is offset in a first direction along a plane perpendicular to the central axis and the second conductor extends away from the central axis, in a second direction along the plane, opposite the first direction.

2. The electrical device according to claim 1, further comprising an additional connecting region offset in the second direction along the plane, the additional connecting region connecting 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.
