Housing for electrical device e.g. control circuitry in motor vehicle, has contact spring which makes contact with grounded surface of circuit board when device is assembled

摘要

An electronic circuit on a circuit board is arranged in a housing (1) made chiefly of electrically conductive materials. A wall supported by the housing forms a nearly interference-free chamber, and is connected to the ground terminal of the circuit board. At least one contact spring is attached to the wall. When the device is assembled, one end of the contact spring comes to abut the contact surface of the circuit board that is connected to ground.
