Abstract

A screening element for increasing the electromagnetic compatibility of electronic functional groups. The electronic functional groups being at least partially surrounded by electrically conducting, screening housing walls or containing printed circuit boards which have electrically conductive screening areas. The screening element forming an intermediate element for providing a sealing conductive bridge between screening areas. In the preferred embodiment, the screening element is in the form of a profile seal. The profile seal is composed of at least one compressible or elastic layer of conductive material which is applied directly to a surface of a support element.
