Abstract

An electrical device, especially a sensor for a motor vehicle, is adapted to be fastened on a mounting surface. The device includes a housing and a support plate. The support plate is rigidly linked with the housing through at least one connecting element. The support plate carries at least one electronic component that reacts to structure-borne noise and that is mounted in the immediate vicinity of the connecting element.

Claims

1-10. -10. (canceled)

11. A vibration sensor assembly, comprising:

a housing configured to be fastened on a mounting surface, said housing including;

a housing jacket formed of a rigid material and configured for fastening to the mounting surface; and

a housing cover formed of plastic material and configured as a plug connector;

a support plate fastened in said housing;

an electronic structure-borne noise sensor disposed on said support plate, configured to detect vibrations and to be contacted via said support plate;

said plug connector having at least one contact element extending from an exterior to an interior of said housing to facilitate an electrical and mechanical connection with an adapter of corresponding design on the exterior of said housing and with said support plate in the interior of said housing;

at least one connecting element rigidly connecting said support plate to said housing jacket under pressure, said electronic structure-borne noise sensor being disposed in an immediate vicinity of said at least one connecting element.

12. The sensor assembly according to claim 11, wherein said sensor is configured to detect structure-borne noise signals in a motor vehicle.

13. The sensor assembly according to claim 11, wherein said connecting element presses said support plate against said housing jacket substantially without another element inserted therebetween.

14. The sensor assembly according to claim 11, wherein said support plate is fastened by a clamped connection between said housing jacket and said housing cover for transmitting structure-borne sound waves generated in said mounting surface.

15. The sensor assembly according to claim 11, wherein said housing cover is formed with a number of openings equal to a number of connecting elements, and a bushing is inserted into each said openings and a clamping force acting on said support plate is effected by said bushings and said housing jacket.

16. The sensor assembly according to claim 15, wherein said bushings protrude beyond an interior face of said housing cover.

17. The sensor assembly according to claim 15, wherein said bushings are made from metal and have injection molding around an exterior thereof formed of a common material with said housing cover.

18. The sensor assembly according to claim 11, wherein said housing jacket is a metal housing jacket.

19. The sensor assembly according to claim 11, which comprises a sealing compound on an exterior of said housing cover for sealing an interior of said housing.

20. The sensor assembly according to claim 11, wherein said housing is formed with at least one mounting flange, and said mounting flange has an opening formed therein extending substantially perpendicular to the mounting surface and enabling a further fastener to pass therethrough for fastening said housing to the mounting surface.
