ABSTRACT:
A structure for the shielding of electronic components from outside electromagnetic fields is to be designed in such a way tha a single printed circuit board serves both to separate a "polluted" space from a "clean" space and to accommodate the components of the device to be shielded itself. To this end, the printed circuit board has a first region which is provided with an internal, grounded conductive coating, and a second region which carries the electronic components to be shielded. A housing forms a shielding partition which extends to the printed circuit board and has an end face engaging the printed circuit board between the first and second regions. The first chamber is limited by the first region of the printed circuit board. Shielding for blocking electromagnetic fields are provided in the printed circuit board adjacent partition. These shielding extend transversely to the surfaces of the printed circuit board. Through-contacts of connecting lines extending to the electronic components in the first chamber extend insulatedly through the internal, grounded conductive coating. The connecting lines furthermore extend along the printed circuit board on the side of the grounded conductive coating remote from the first chamber and insulatedly through said transversely-extending shielding to the electronic components.
