Execution of plug-in modules in a multiple

Larger electrical systems »such as data processing systems or Control systems are currently almost exclusively divided into individual plug-in assemblies. The division is made as follows: that for a system in as many places as possible the same assemblies possibly even with slightly different ones Punctures can be used.

'' In the case of wide circuit boards in particular, this can lead to that the plugging of the module is very difficult or even impossible is made ». A strong curvature can also result in contact of components and conductor paths between neighboring assemblies or cause mutual damage when stalling.

The desired dense assembly of the plate with components and, above all, the increasing use of so-called integrated building blocks as a result of the Artificial ventilation is relatively high fore-pleasure necessary. Such ventilation is only effective if it is ensured that the blown cooling air v / really flows along the inserted assemblies and does not escape to the side. In principle, this could be done by a Cabinet construction can be achieved «

ISs also often want that - especially for test purposes - certain measuring points during operation the assemblies for checking characteristic stresses or signals are accessible from aui3cn or all of them Assemblies can be exchanged. However, this does not relate to the need to have a closet during the Keep operations closed.

The invention is therefore based on the object in the construction
