Abstract

Abstract The invention relates to a shielding element for electromagnetically shielding an aperture opening formed, for example, in a metallic structure, a plug holder or a component housing. In the non-deflected state, a large number of conductive contact springs extend from the frame of the shielding element towards the aperture opening. The contact springs at least partially overlap one another and close the aperture opening. When a plug-in element is inserted into the aperture opening, the contact springs are deflected in the insertion direction and rest in a sprung manner on the component. The invention provides an automatically closing radio-frequency seal for an aperture opening.
