The present invention relates to an electromagnetic shielding device. Further, the present invention relates to a arrangement for electromagnetic shielding of two adjacent relatively movable members having opposed surfaces with a space therebetween. The electromagnetic shielding device includes a resilient cap portion having a center portion and a plurality of segments extending radially outwardly therefrom. An arrangement for retaining the cap portion on one of the surfaces is provided. The retaining arrangement includes a thin disk adapted to be received between the segments of the cap portion and resilient tongues extending radially inwardly from an outer end of each of the segments. The cap portion in a free state has a height which is greater than the distance of the space between the opposed surfaces to be shielded. In this way, the cap portion is compressed to fit within the space upon movement of the members toward one another to ensure electrical connection between the two opposed surfaces.
An arrangement for electromagnetic shielding of two adjacent relatively movable members having opposed surfaces with a space therebetween, the arrangement comprising at least one individual shielding element arranged on one of said surfaces, each shielding element comprising a generally circular resilient cap portion having a plurality of radially extending segments and resilient tongues extending radially inwardly from an outer end of each of the segments to define a semi-closed, generally annular space between the segments and the tongues and means for retaining said cap portion on said one of said surfaces, said cap portion overlying said retaining means.
