1. A device for the connection of shieldings of multi-pole plugs having a spring strip housing, the plugs associated with a module printed circuit board, to the grounded potential layer of a mother printed circuit board containing a plurality of contact blades residing perpendicularly thereon, comprising:

  • two longitudinal shields arranged on opposite sides of the module circuit board and having spring elements arranged such that, in the plugged condition of the plug, the spring elements resiliently press against allocated contact blades conductively connected to the grounded potential layer of the mother printed circuit board;

    the longitudinal shields each having an angled-off shielding plate shielding a portion of the respective side of the module printed circuit board;

    shielding plate hooks that can be engaged to the spring strip housing and are attached to the individual longitudinal shielding plates at lateral edges pointing in the direction of the mother printed circuit board;

    press-in pins connected to a lateral edge of the angled-off shielding plates with which the shielding plates are connectable to a grounded potential layer present on the module printed circuit board;

    two respective face shielding plates each oriented having an end face plate substantially perpendicular to the module printed circuit board for shielding an end face of the shielded spring strip housing, and having a spring region in the region of the contact blades;

    the face shielding plates are bent off from said end face plate adjacent the longitudinal shielding plates and are connected to the longitudinal shielding plates by spot welds;

    the face shielding plates are connected to the grounded potential layer of the module printed circuit board via press-in pins at the edges of said end face plates adjacent the module printed circuit board; and

    the edge regions of the end face plate of the face shielding plates located in the region of the contact blades and neighboring the spring regions are partially overlapping and are connected to one another by bending over erect sheet metal tabs.
