RF-shielding housing for a circuit, for example for the control circuit of a motor-vehicle air-bag
First Claim
1. A metallic or metal coated housing which provides shielding against radio frequency radiation, comprising:
- a first housing section and a second housing section,a printed circuit board mounted in said housing and supporting at least a part of a circuit,a plug in said first housing section having plug terminals connected to said circuit,a bay in said first housing section having metallic or metal coated walls and in which said plug is arranged, said bay having an opening with edges lying in a single plane facing said printed circuit board, which covers said openingsaid printed circuit board having an electrically conductive layer over a large area facing said opening with strips of said electrically conducting layer resting on edges of said opening so that said electrically conducting layer is at housing potential.

Abstract
An RF-shielding multicomponent metallic or metal-coated circuit housing (W, D) contains a printed circuit board (L), and a plug (S) which is connected to plug terminals (P) provided in the printed circuit board (L). A housing section (W) has a bay (E/B) which has metallic or metal-coated walls (B) which are at housing potential in the assembled state of the housing (W, D) and in which (E/B) the plug (S) is mounted. The bay (E/B) is open at one side face (M), the "open side face" (M), facing the inside (Q) of the housing, the bay (E/B) having edges (C) situated in a single plane and facing the open side face. The open side face (M) is covered by the printed circuit board (L) in the assembled state of the housing (W, D). The printed circuit board (L) is coated over a large area of its section (M) facing the bay (E/B) with a conducting layer (M) in such a way that strips of said layer (M) rest on the edges (C) in the assembled state of the housing (W, D) so that the layer (M) covers the bay (E/B) and the layer (M) is then at housing potential.
