Abstract
A system is provided for positioning a plurality of cards in an electronic module intended to be plugged into a backplane. The system includes a spacing element comprising a succession of spacers of increasing section (diameter). Spacers are arranged end to end and are preferably cylindrical. The difference of section between successive spacers forms a kind of stair step or shoulder. These successive steps position the electronic cards parallel to one another, with a predetermined spacing which corresponds to the spacing of the backplane connectors. Fastening means, such as a nut, are associated with the steps for maintaining the cards. The cards are bored so that the spacing element can be inserted and the nuts applied. The size of the hole in each card is such that the surface around the hole can be pressed against the corresponding shoulder by means of the nut installed on the opposite side.
