The mechanism establishes electrical connection of two printed circuit boards of separate devices that form individual modules within a stackable module system. In order to achieve a simply constructed connection mechanism, the printed circuit boards respectively have centering or spring clips into which an adapter assembly is pluggable. The adapter assembly is thereby composed of two blade or spring clips firmly connected to one another via an adapter assembly printed circuit board, whereby the adapter assembly is surrounded by shielding covers firmly connected to one another. In the plugged condition, the adapter assemblies are conducted through housing openings in oppositely residing housing parts of the devices stacked above one another, whereby the outsides of the shielding covers contact the surrounding edges of the housing openings.

A communication system including a switching system and a main distributor connected thereto via internal central office lines for the connection of the subscriber network lines is provided. To provide a simple and cost-beneficial communication system, a self-supporting wiring backplane is used having an upper end where the individual system assemblies of the switching system can be hooked and plugged by a downward swivel connection. The terminal strips (splitting strips) of the internal side of the main distributor have exchange-side terminals pressed in on the same wiring backplane under the system assemblies.

The invention is directed to a plug-type connection composed of blade connector and spring clip, whereby the individual contact passages are surrounded by electrically conductive shielding plates that are connected to shield contactings carrying a ground or shield potential. The shield contactings are to an intermediate shielding grid system located both at the backplane side and at the circuit board or module side. In order to achieve an improved interconnect passage width between the contact blades and the shield contactings arranged in the intermediate grid, the electrical connection between the connector or spring clip and assembly printed circuit board ensues on the basis of pressure of spring-like bent terminal ends which flatten onto contact surfaces on the assembly printed circuit board.

A plug-type connector is provided having shield elements that surround signal-carrying conductor parts. Shielding plates are placed in slots in walls of receptacle chambers which house a spring contact strip. Shield elements are disposed in slots in a wall or floor of the blade connector. The shielding plates of the spring contact strip (8) include transverse shielding plates (14) and longitudinal shielding plates (13) fashioned comb-like so that they interfit and interconnect. The shielding plates (13, 14) are provided with incisions of a predetermined width at a front region of the receptacle chambers (11), having the respective corners bent off in a predetermined direction. Thin, additional contact pins (3) are anchored in the blade connector (1) and are connected to ground. These pins (3) are provided at the intersections of the shield elements and contact the shielding plates (13, 14) of the spring contact strip (8) at four points in the front region of the receptacle chambers (11).

The invention is directed to a coding device for electrical assemblies that can be inserted parallel to one another into a module frame and that are contacted via plug devices attached at the back to a wiring backplane. A coding flange having three quadratic openings arranged in a right angle pattern is arranged on the wiring backplane between the guard rails, and a corresponding coding housing likewise provided with three quadratic openings arranged in a right angle pattern is arranged on the assembly next to the plug connector. Coding pins can be selectively oriented within the openings by 90.degree. turns, whereby the free ends of said coding pins are fashioned as tongues having a rectangular cross-section, and the area of the cross-section of the tongues corresponds to half the area of the cross-section of the quadratic openings.
