Abstract

The invention relates to a housing (1) for an electric device, comprising at least two housing parts (2) and an electronic circuit mounted on printed circuit board (5) that can he placed in the housing (1). A connecting device for supplying power to the device and/or transmitting signals to the electronic circuit and which can be fixed on the housing (1) is also provided. A housing wall (4) integral with one of the housing parts (2) forms an interference radiation-safe chamberlike cavity (3) for receiving the connecting device after the housing parts have been assembled. At least one electrically conductive contact element (6) is also provided between the housing wall (4) of the chamber (3) and the conductors of the printed circuit board (6), which are connected to the earth terminal of the housing.

Claims

1. A housing for an electrical device having

at least two metallic housing parts (2) and an electronic circuit on a printed-circuit board (5) that is capable of being attached in the housing (1), and having

a connection device for the power supply of the housing and/or signal transmission to the electronic circuit that is capable of being attached to the housing, wherein

a conductive housing wall (4) that is interconnected mechanically and electrically with one of the metallic housing parts (2) is provided, with which said housing wall—

after the metallic housing parts (2) are joined—

forms an interference radiation-proof, chamber-like recess (3) to accommodate the connection device, whereby at least one electrically conductive contact element (6) is located between the housing wall (4) of the chamber (3) and the conductor tracks of the printed-circuit board (5) connected with a ground connection of the housing.

2. The housing according to one of the preceding claims,

wherein at least one contact element (8) is located between a cover (50) and conductor tracks of the printed-circuit board (5), whereby the conductor tracks are connected with a ground connection of the housing.

3. The housing according to one of the preceding claims,

wherein the contact elements (6), (8) are designed as contact springs.

4. The housing according to one of the preceding claims,

wherein both the housing wall (4) and/or the cover (5) have at least one integral projection.

5. The housing according to one of the preceding claims,

wherein both the housing wall (4) and/or the cover (50) have at least one integral projection to which an electrically conductive contact element (6), (8) is attached.

6. The housing according to one of the preceding claims,

wherein the gap heights 20 and 25 are set so that components 30 and 40 can be situated in the gap region.

7. The housing according to one of the preceding claims,

wherein capacitors are located in the gap region.

8. The housing according to one of the preceding claims,

wherein the housing wall (4) is integrally joined with the housing part (2).

9. The housing according to one of the preceding claims,

wherein the housing (1), the housing part (2), the cover (50), and the housing wall (4) are produced out of die-cast aluminum.

10. The housing according to one of the preceding claims,

wherein the electrical device is an open-loop or closed-loop controlling system for an electromechanical component in a motor vehicle.
