Module rack having at least one front facing groove for mounting components thereto

As is conventional module racks are used for receiving so-called plug-in modules having electric circuits and components mounted on a printed circuit board. The circuit boards, as a rule in rather large numbers, are inserted standing vertically adjacent to one another into the module rack, with the assistance of snapped-in guide rails. To cover the front, each plug-in module has a front panel. The front panels of vertically mutually adjacent plug-in modules constitute a nearly continuous cover on the front of the module rack. A module rack has on its front at least one upper and one lower crossrail and at least one left and one right vertical corner profile strip. A vertical mounting groove is formed in at least one vertical corner profile strip. The vertical mounting groove faces away from the front of the module rack. Additional fastening capabilities may be provided on the front of the module rack. These additional fastening capabilities are used for external add-on parts such as a covering box, a handle, and cover panels. The module rack may be used for e.g., plug-in modules having electric circuits and components mounted on a printed circuit board.
