ABSTRACT:
A circuit card face plate with an elastomeric, electrically-conductive seal that provides electromagnetic compatibility sealing and air flow control for a front panel of an electronic equipment frame. The seal gasket is in electrically-conductive contact with the face plate and an adjacent face plate, thus, with all cards in place, an air flow barrier and an electrically-conductive surface is established. To this end, an elastomeric, electrically conductive seal in a modified figure-eight cross-section provides a close fit with minimal lateral pressure being exerted on adjacent cards. Further a pin on both the top and the bottom of the face plate inserts into a hole on an upper and lower rack shelf maintain alignment of the cards when they are in the frame.
