1. A device for assembly and power supply of a plurality of electrical apparatuses such as power apparatuses and auxiliary units fixed onto an assembly rail and having modular cases adjoined side by side, comprising a common means for connection of all the electrical power apparatuses extending parallel to the longitudinal direction of the rail and having a succession of connecting teeth arranged longitudinally at preset intervals for insertion in the corresponding power supply terminals of said apparatuses, characterized in that the above-mentioned means for connection comprises at least one tooth (9) on which there is fixed a spring (10) designed to cooperate with a wall (14) of the corresponding terminal (2) of the apparatus to provide the contact pressure between the tooth (9) and the corresponding connecting strip (15) of the apparatus. 2. The device according to claim 1, characterized in that the or each spring (10) comprises a flexible blade (11) folded appreciably into a U shape, one (12) of whose branches (12, 13) is fixed to the tooth (9) whereas the other branch (13) is designed to press against an internal wall (14) of the terminal (2) in the connected position of the comb (6). 3. The device according to claim 1 or 2, characterized in that the or each power supply terminal (2) comprises a screw tunnel and that the or each spring (10) presses on the wall (14) of the tunnel opposite the screw (16). 4. The device according to any one of the claims 1 to 3, characterized in that the or each spring (10) is fixed onto the corresponding tooth (9) by clipping. 5. The device according to any one of the claims 1 to 3, characterized in that the or each spring (10) is fixed onto the corresponding tooth (9) by soldering. 6. The device according to any one of the claims 1 to 5, characterized in that the means for connection is a connecting comb. |
