CA 2218570

A contact element having at least one leaf spring 2, 3 has a U-shaped contact means 6, the two U-legs 8, 9 of which taper towards their ends and can be elastically deformed with respect to each other. This contact element 1 is introduced into a guide groove 22 of a guide rail 13 of a module support structure or the like. The leaf springs 2, 3 thereby contact a printed circuit board which can be inserted into the module support structure and the contact means 6, together with guide rail 13, can be clamped in a positioning hole 15 of a module rail 16 of the module support structure to thereby establish electrical contact with the module rail 16. In this manner, the interfering effect of an anodized layer on the module rail 16 is circumvented.

Cette invention concerne un dispositif de contact formé d'au moins un ressort à lame 2, 3 et comportant un moyen de contact en U dont les deux branches élastiques 8, 9 s'amincissent vers leur extrémité et peuvent être déplacées l'une par rapport à l'autre. Ce dispositif de contact 1 s'insère dans une rainure 22 d'un profilé de guidage 13 d'un bâti modulaire ou montage analogue. Les ressorts à lame 2, 3 entrent ainsi en contact avec la carte à circuits imprimés placée dans le bâti et le moyen de contact 6, en conjugaison avec le profilé de guidage 13, se verrouille dans un trou de positionnement 15 d'un profilé 16 du bâti modulaire, établissant le contact électrique avec celui-ci. De cette façon, on contourne l'effet isolant de la couche anodisée du profilé 16.
