ABSTRACT:
A multi-pole plug mechanism has a centering strip emplaceable onto a connection board for receiving a plug, the centering strip including a shield electrically connected to regions of the chassis holding the connection board and which are connected to ground. The shield is formed by a plurality of shield elements having shielding surfaces aligned parallel to the plug-in direction and that resiliently press against a shield of the plug in the plugged condition. The centering strip is composed of a bottom plate with passages therethrough for contact blades and comprises angular spacers per prescribed unit length in the respective corner regions that have seats for the contact blades in the free end regions. The shield comprises two metallic longitudinal spring strips and two metallic transverse spring strips including cooperating recesses and hook structures for mutual connection thereof and simultaneously form the entry region for plug sections as shielding per prescribed unit length.
