Abstract
Abstract An electrical installation is composed of individual subassemblies with a subrack, and the relative positional accuracy needed to unite the plug-in and mating connections. Furthermore, a plastic holder featuring a hole to accommodate the plug-in connections is provided on the subrack, and a spring part is provided at a defined distance to this hole. Positioning holes are available on a bus board belonging to the subrack at a defined distance from the plug-in connections. At least two projections adapted in position and shape to the positioning holes are provided on the side of the plastic holder turned away from the subassemblies. In the joined state of the bus board and the plastic holder, the plug-in connections extend into the holes. The subassembliles are brought by the spring part over a support part into a position suited for sliding the mating connections on to the plug-in connections.
