ELECTRICAL CIRCUIT CARD WITH REDUCED EMI EMISSION

An electrical circuit card adapted to be inserted into a grounded, electrically conductive housing comprises and insulative circuit board, an insulative faceplate coupled to the circuit board along the front edge thereof, and an electrically conductive shielding strip or shunt located behind the faceplate for reducing EMI emissions from the circuit card. The shielding strip comprises an intermediate portion extending generally vertically along the rear surface of the faceplate, and upper and lower contacts adapted to be brought into electrical contact with the housing when the circuit card is inserted into the housing. At least one of the upper and lower contacts is arranged to be brought into contact with a non-outwardly facing surface of the housing, such as the edge of a designator strip located above or below the opening in which the circuit card is received. The use of a non--outwardly facing housing surface for making contact with the shielding strip simplifies the manufacture of the designator strip by eliminating the masking step necessary to provide a bare metal contact area, improves the appearance of the finished designator strip while allowing more space for printed indicia, and affords a contact surface which is less likely to accumulate dirt and other contaminants.
