Abstract
Spring elements are located at shielding caps of printed circuit board or cable connections such that they resiliently press against contact elements in the plugged condition, the contact elements being electrically connected to the ground potential layer of a mother board. Contact blades or reinforcing plates extending perpendicularly to the mother board serve as the contact elements. The spring elements, depending upon the position of the contact elements or the shape of the shielding caps are located at the insides or outsides of the shielding caps or are fashioned at the edges thereof which are directed towards the mother board.
