Abstract:
An electromagnetic interference (EMI) shielded vent panel for disposition over a corresponding opening formed within a surface of an enclosure for electronics, said vent panel comprising:an electrically-conductive frame having a perimeter defining a closed geometry configured to border the opening of the enclosure, said frame including a pair of opposing side walls each having a proximal and a distal edge, and an end wall which extends intermediate the proximal edges of said side walls, each of said side walls having an outer surface and an inner surface spaced-apart from the inner surface of the other of said side walls; and one or more layers of an electrically-conductive media having an outer periphery and extending along a transverse axis intermediate a pair of faces defining a thickness dimension therebetween, said media have a plurality of ventilation passageways extending through said thickness dimension generally along said transverse axis; the outer periphery of said media being retained intermediate the inner surfaces of said side walls, wherein at least one of said side walls is formed as having a series of spaced-apart first tabs defined therein along the perimeter of said frame, each of said first tabs having a proximal end and a distal end contacting said media effective to provide electrical continuity between said frame and said media.
