  • Patent number: 5001297
    Abstract: An electromagnetic shielding device for use along gaps between relatively movable surfaces of doors, access panels, drawers, and cabinets, etc., includes an electrically conductive shielding strip formed of longitudinally arranged segments integrally connected by a carrier strip. Each segment is mounted on a corresponding segment of a mount track which is adapted to securely lock the shielding strip in place. The design of the electromagnetic shielding device of the present invention provides enhanced capabilities of electromagnetic shielding as well as improvements in structural rigidity and mechanical durability. The design also facilitates installation of shielding in confined areas and repair of damaged shielding.

  • Patent number: 4754101
    Abstract: An electromagnetic shield includes electrically conductive walls arranged to form a closed boundry. The walls include pins projecting from a lower edge to secure the shield on a printed circuit board and to provide a connection to a conducting layer in the printed circuit board and engagement prongs on the upper edge to engage a cover plate.

  • Patent number: 4543447
    Abstract: 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.
