  • the accessibility of the installation locations of the electrical equipment may be different.
  • the customer of an electrical device is therefore the manufacturer of the shape of the contact before, whereby also the shape of the connector is specified.
  • the invention provides an electrical device for a motor vehicle, in particular a sensor, with a housing for receiving an electronic circuit and a connector for electrically contacting the electronic circuit of the electrical device with a contact plug.
  • the connector is designed as a separate component from the housing, which comprises a first connection element.
  • the connector has first electrically conductive contact portions with respective inner and outer ends, wherein the inner ends are arranged in the region of the first connection element and the outer ends are arranged in the region of a chamber of the connector.
  • the housing comprises a second connection element, which is designed to be complementary to the first connection element of the connector, wherein outer ends of second electrically conductive contact sections are arranged in the region of the second connection element.

  • the electrical device according to the invention is characterized in that the housing and the connector are two separately developable and manufacturable components.
  • the connector in this case forms a connectable to the housing adapter, which is electrically and mechanically connected to the contact plug.
  • the bipartition of housing and connector makes it possible to provide in large numbers an identical housing with embedded and trained electronic circuit.
  • the connectors can then be specifically designed in a smaller quantity according to the specifications of respective customers in a cost effective manner and manufactured.
  • Characterized in that the first and the second connection element of the connector and the housing are always adapted to each other regardless of the geometric configuration of the connector, the intended functionality can be provided.
  • An electrical device according to the invention can therefore be developed in a shorter time and produced at lower costs. In addition, the production can be done with a reduced number of tools.

  • the first contact sections can be designed bent, for example, in a suitable manner.
  • the inner and outer ends of the first contact portions of the connector are electrically connected to each other via a rewiring device.

  • the outer ends of the second contact portions are formed such that to the inner ends of the first contact portions, a mechanical contact, in particular a Plug contact, is made when the connector is connected to the housing.
  • the connector is secured by a device against rotation relative to the housing when the connector is connected to the housing. In this way, on the one hand, a correct connection of housing and connector can be ensured. On the other hand, it is ensured by the device against rotation, that in the interconnected state separation of the electrical contact of the mechanically interconnected outer ends of the second contact portions and inner ends of the first contact portions is impossible.
