Abstract
A method is provided for EMC screening of a cable connection to an electrical apparatus that includes an enclosure defining an opening for the cable, the enclosure including a conductive internal wall to which a screen portion of the cable is to be electrically connected. The method includes (i) folding back a portion of cable screen along the length of the cable; (ii) positioning (e.g., inserting) the cable into a sleeved grommet including a conductive elastomeric material and having an inner surface, the grommet being sized so as to compress the folded back cable portion against the conductive inner surface of the grommet. The grommet further includes a circumferential groove in an outer surface thereof for being positioned in the enclosure opening so that the groove holds the grommet in the opening and the conductive material of the grommet is in direct electrical contact with the conductive internal wall of the enclosure. The grommet may include silicone elastomeric material having a silver/glass conductive filler.
