    摘要: An apparatus for preventing leakage of electromagnetic radiation from a modular electronic planar substrate surrounded by an enclosure that includes a bottom portion, a top portion, a first side portion having apertures adapted for receiving electronic cables, and a second side portion having electrical connections therein. The apparatus includes a bracket having a first end and a second end, the bracket connected to the first side portion, wherein the bracket includes an interior portion and an outer portion which contiguously form a first bracket wall, a second bracket wall and a third bracket wall, such that the second bracket wall is positioned approximately perpendicular to the first bracket wall and the third bracket wall. A first cover and a second cover each have Z-sectional bends which contact the interior portion of the bracket at the first bracket wall and the third bracket wall to respectively form sealed seams which prevent electromagnetic radiation associated with the electronic planar substrate from leaking beyond the enclosure. In addition, the apparatus includes a first grounding spring and a second grounding spring respectively mounted at the first end and the second end of the bracket to provide a ground path from the enclosure to associated enclosures and assist in preventing the electromagnetic radiation associated with the electronic planar substrate from leaking beyond the enclosure. The interior portion of the bracket wraps about the first side portion and flattens the first cover and the second cover respectively against the first bracket wall and the third bracket wall to provide rigid structural support to the enclosure.
