    Patent number: 5934915
    Abstract: A device for earth-connecting a first printed circuit board and an associated first board front with multiple printed circuit boards and associated board fronts in a magazine includes a board spring for each printed circuit board. The board spring is mounted on the printed circuit board and extends from an edge of the printed circuit board in a general U-shape into resilient abutment with the board front associated with the printed circuit board. Each board front has a generally U-shaped profile and is mounted on the associated printed circuit board with its legs parallel with and directed towards the associated printed circuit board. A shielding spring embraces one of the legs of the board front and extends along a whole of the board front, such as to clamp a free edge of the leg.
