Abstract
A metal housing for electronic devices configured for electromagnetic compatibility includes a housing body whose opening can be closed by a closing element. Metal contact faces are provided around the opening at the housing body and correspondingly at the closing element. Thin contact strips of electrically conductive and corrosion resistant metal are applied to the contact faces. These contact strips may be subsequently melted or welded on by means of a laser beam as a weld trace or as a thin metal foil. To seal the groove between the housing body and the closing element against interfering electromagnetic radiation, the contact faces are brought into a good electrically conductive connection with one another by way of the bare metal surfaces of the contact strips applied thereonto, for example by means of an intermediately disposed elastic and electrically conductive seal.
