ABSTRACT:
The invention relates to a screening device comprising: a screening cover, which covers an electronic circuit located on a printed circuit board and comprises an edge that is separated from the component side of the printed circuit board by a gap and a contact device, which is located in the gap and produces an electric connection between the screening cover and a conductive contour element on the printed circuit board. According to the invention, lugs are formed on the edge of the screening cover, said lugs fixing the screening cover on the printed circuit board and maintaining an elastic pretension on the contact device. The contact device is configured as an elastic sealing body that extends continuously through the gap and absorbs electromagnetic waves.
