Abstract: A current sensor device for measuring a current, in particular for measuring a battery current in motor vehicles. The device includes a clamping device for fixing the current sensor device to a maintaining body, an electric resistance element on which the current can be measured by means of a voltage, and an electric mass element by means of which the current sensor device can be electrically coupled to a zero potential. The clamping device, the resistance element and the mass element are integrally formed.

Abstract: A current sensor device for measuring a current, in particular for measuring a battery current in motor vehicles, including an electric resistance element on which the current can be determined by means of a voltage, and a first and a second connection element which are electrically connected to the resistance element and are arranged on different sides of the resistance element. The resistance element and the connection elements are integrally formed.

Abstract: A fastening device for fastening an assembly in an opening of a wall of a vehicle includes a supporting element to be placed on the vehicle wall and a retaining element having at least one retaining wing that fastens the device in the vehicle wall opening. The retaining element is rotatable relative to the supporting element between fastened and unfastened positions. For a tool-free mounting and fastening, the retaining element further includes a graspable rotating wing that has a grasping surface which is inclined at an angle in the direction of rotation, whereby the manual grasping force applied by the installer exerts a force component in a rotational direction to rotate the retaining element, and a force component in an axial direction to press the fastening device against the vehicle wall. Preferably the wing includes a wing wall and reinforcing webs.

Abstract: A fastening device for fastening an assembly in an opening of a wall of a vehicle is described. The fastening device has a supporting element (2) to be placed on the wall (1) and a retaining element (3) having at least one retaining wing (3.1) for fastening the fastening device in the opening (1.1) of the wall, wherein the retaining element (3) for fastening the fastening device is rotatably arranged relative to the supporting element (2), i.e., the retaining element (3) allows a quarter-turn fastener solution. In order to be able to mount without tools, at least one rotating wing (3.2) is arranged on the retaining element (3) and has a grasping surface (AF) in the direction of rotation for fastening the fastening device, said grasping surface being inclined at an angle (?) at least in the direction of rotation toward the direction of rotation and toward the wall. However, increased effort is usually required to remove inclined surfaces from injection molds. Therefore, the rotating wing (3.
