Abstract
A shielded mounting rack has a shielding plate (11) on its rear, which shielding plate (11) covers the back-panel wiring and is provided with apertures (12) for shielded plug connectors (1) which can be plugged on at the rear. The latter are in each case provided with a shielding casing (3) which has feathered contact tongues (4) which make contact with circumferential ground contact pins (10) on a back-panel wiring board (8). The ground contact pins (10) project into the apertures (12) in the shielding plate (11) and are pressed, by the contact tongues (4), against its inner wall. As a consequence, a fine-meshed ground connection is produced between the plug connector (1), the shielding plate (11) and the back-panel wiring (8).
