Abstract:
An electromagnetic interference (EMI) shielded vent panel comprising:an electrically-conductive frame having an inner and outer margin which enclose a frame opening, the frame comprising: a first frame member having an inside and outside face, and an inner perimeter and outer perimeter, the inner perimeter defining a first opening; a mating second frame member having an inside and outside face, and an inner and outer perimeter, the inner perimeter defining a second opening disposable in registration with the first opening of the first frame member to define the frame opening; and a projection depending inwardly from the inside face of both of the first and second frame members intermediate the inner and outer perimeter thereof, the projection extending along at least a portion of the frame opening; and one or more layers of an electrically-conductive media supported within the frame opening, the media having an outer periphery and extending in a thickness direction intermediate a pair of faces, the media have a plurality of ventilation passageways extending through the media faces in the thickness direction, and the media faces being interposed between the inside faces of the first and second frame member with the first and the second opening of the frame members being disposed in registration to define the frame opening, and with the outer periphery of the media overlapping the projection of the both of the first and second frame members, whereby the projection of the both of the first and second frame members engages the media inwardly of the outer periphery thereof to thereby positively retain the media within the frame.
