Abstract

A shielding housing (1) cooperates with at least one conductor surrounding at least one component on a printed circuit board to electrically shield said at least one component. The shielding housing (1) comprises a shielding element (2) which carries a serrated, elastic shielding gasket (4), which is adapted to cooperate with said at least one conductor. The housing (1) is adapted to be pressed with its serrated gasket (4) against said conductor on the printed circuit board.
