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.

Electrical installation composed of individual subassemblies

The invention consists of a box-shaped electrical assembly with a frontal cover and screw connections for the connection of leads accessible from the front. The cable lead openings to the screw connections are located in an open-to-the-front, longitudinal channel located at the front of the assembly. The cover acts as a labeling plate and also functions as a cover for the longitudinal channel and for the screw connections. The screw connections electrically connect an external cable to a plug unit subassembly. The plug unit is connectable with a circuit board enclosed within the assembly. The plug unit is provided with a pivotal axis, and is adapted for connecting to a plug strip that is mechanically and electronically connected to the circuit board.

Box shaped electrical assembly

An automating assembly for electrical installations comprises a plurality of input and output modules each detachably fastened to a respective modular module carrier removably attached to a support bar. The module carriers each include an integrated circuit connectable to the integrated circuits of adjacent module carriers by means of rigidly mounted plug strips and cooperating jack strips connected to the integrated circuits of the module carriers via flat flexible cables. Each modular module carrier is connected to a respective terminal block for the coupling of external wires to the automating assembly. The module carriers are designed to facilitate the removal of individual module carriers for applications in which a reduced number of input and output modules is required.

Electrical assembly with modular carriers for signal processing modules

The invention concerns an electrical system consisting of removable, variably sized, individual sub-assemblies interconnected electrically and physically with an assembly carrier. This assembly carrier provides mounting for connectors of various configurations which mate with the individual sub-assemblies, and also provides mounting for the sub-assemblies themselves. The sub-assembly mounting is by means of a U-shaped projection on which each sub-assembly attaches and then pivots into its secured position. The sub-assembly electrical connectors are mated to the assembly carrier connectors during this pivoting into position. The U-shaped projection is surrounded in a direction perpendicular to the carrier by guide plates providing lateral location and separation of the variably-sized individual sub-assemblies.

A contact spring contained in a conforming recess in a guide channel has a U-shaped portion with projecting side tabs embracing the edge of a circuit board. The side tabs rest against conductors on the circuit board which carry circuit board potentials and establish a good electrical connection between the conductors and the contact spring. The contact spring also grips the circuit board. A spring leg on the contact strip goes through an opening in the guide channel and engages the subassembly carrier.

A mounting structure for boards that can be equipped with electronic devices has structurally identical, adjacent frames, which are linked to each other on right angle lugs and can be flipped open like the pages of a book.

Hinged support for electrical devices

An arrangement for the rotating thyristor excitation [RT excitation] in a turbogenerator which is suited for very high centrifugal force loadings in which the carrier discs of the rectifiers wheels are designed in the form of hubs mounted about the shaft secure against turning and having hollow-cylindrical projections extending axially in two directions to form with the shaft recesses into which the semiconductors including their cooling elements and their protective external components as well as the electronic driver units are disposed along the inside diameter of the cylindrical projection on the hubs.
