Abstract
Abstract An EMC sealed joint is used within electronic equipment to provide compliance with electromagnetic compatibility (EMC) standards. In one example, EMC sealed joints are used with faceplates mounted to printed wiring boards stacked side by side in an electronic equipment rack, for example, to seal the adjacent faceplates against one another and to seal the faceplates to the shelf edge portions in the rack. One type of EMC sealed joint is formed by a concave groove in a side portion of the faceplate, which receives an EMC gasket located on an adjacent faceplate. Another type of EMC sealed joint is formed by protrusions on a back surface of the front portion of the faceplate, which engage a flat surface on a shelf edge portion in the electronic equipment rack.
