PCT No. PCT/SE95/01507 Sec. 371 Date Jun. 10, 1997 Sec. 102(e) Date Jun. 10, 1997 PCT Filed Dec. 14, 1995 PCT Pub. No. WO96/19098 PCT Pub. Date Jun. 20, 1996A 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. The shielding spring is bent away from an outer side of the leg at a small angle so that when the first board front is inserted into the magazine, an outer portion of the shielding spring will contact another board front adjacent to the first board front, thereby making an earth connection between the first board front and the adjacent board front. In this way earth connections between all of the board fronts in the magazine are formed.
