Abstract

A sensor assembly includes a metal carrier plate (2) and a sensor housing (3) made of plastic that contains at least one sensor element. The sensor housing (3) is connected to the carrier plate (2) by means of at least one screw (5) that is passed through a through hole (6) of the carrier plate (2). A screwing channel (7) in the sensor housing (3) is defined by the housing material. As a result, a sensor assembly is obtained where the screwed connection is secure.

Claims

1. A sensor assembly (1)

including a metal carrier plate (2),

including a sensor housing (3) that is made of a plastic housing material and that contains at least one sensor element,

wherein the sensor housing (3) is connected to the carrier plate (2) by at least one screw (5) that extends through a through hole (6) of the carrier plate (2), and

wherein a screwing channel (7) in the sensor housing (3) is defined by the housing material.

2. The sensor assembly according to claim 1, characterized in that the screw (5) and/or the sensor housing (3) is/are adapted to undergo elastic deformation due to a screwing force exerted by the at least one screw acting along a screwing axis (8).

3. The sensor assembly according to claim 2, characterized in that a cavity (9) is arranged between the through hole (6) and the screwing channel (7) such that the sensor housing (3) is supported on the carrier plate (2) at a distance from the screwing channel (7).

4. The sensor assembly according to claim 3, characterized in that the sensor housing includes deformation portions (12, 13) which delimit the cavity (9), and the deformation portions are adapted to undergo elastic deformation due to the screwing force.

5. The sensor assembly according to claim 4, characterized in that the deformation portions are springs or ribs.

6. The sensor assembly according to claim 1, characterized in that the carrier plate (2) is adapted to undergo elastic deformation due to a screwing force exerted by the at least one screw acting along a screwing axis (8).

7. The sensor assembly according to claim 1, characterized in that a cavity (9) is arranged between the through hole (6) and the screwing channel (7) such that the sensor housing (3) is supported on the carrier plate (2) at a distance from the screwing channel (7).
