A plug and socket connection system for an electronic unit, consists of a connection plug for the connection of connecting lines and a socket for receiving the connection plug. In accordance with the present invention, both the socket and the connection plug have at least one linearly guiding guide element for the guiding of the connection plug in correct position upon introduction of the connection plug into the socket and at least one locking element for the detachable locking of the connection plug in the plug socket, the locking elements cooperating by engagement in at least two positions.

Plug and socket connection system for an electronic unit

In the case of a modular electrical installation, for instance a modular programmable controller, the bus is modularly configured on the modules, so that the bus is automatically propagated when the installation is assembled.

Self-mounting bus

A box-shaped module has a design whereby the automated manufacture and assembly of these modules and their components is possible in simple, sequential steps. For this purpose, a housing shell is provided with conical spigots for positioning a printed circuit board and a ground terminal. The latter is able to be locked into place via a projection in a depression of the housing shell. Plug and socket connections and holes which are used for positioning are provided on the printed circuit board at a fixed distance to each other, which serves to guarantee a meeting of the plug and socket connections with the mating terminals while the module is being inserted into a mounting rack.

Rack mountable box shaped module with conical positioning elements

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

An electronic module includes a front fin, a printed circuit board having connected terminals, a status display including a plurality of fiber optic guides which lead into the fin and serve as light-emitting elements, a front panel connector, and a front door attached to the front panel connector. The fin may include a bar on a housing shell which projects to the front side and of a counterpart bar on a housing cover. The plurality of fiber optic guides may be combined into one fiber optic comb. A swivel may be used to connect the front panel connector to the module. Flexible hinges may be used to connect the front door to the front panel connector and to mount the light-emitting elements to the printed circuit board.
