Mounting system with integrated display and control elements for plug-in and Subrack systems

The invention relates to a fastening system with integrated display and/or control elements as well as electronic components such as LEDs, membrane buttons or keyboards with a small installation depth, which are integrated into the fastening system from the front or from the rear and which are attached to the plug-in and/or the subrack system.

Conventional plug-in and/or subrack systems use mounting flanges that are attached to the plug-in and/or subrack systems. Separate front panel inserts are used for status displays or special user interfaces, with the display and/or control elements built into them. These elements are usually attached from the back of the front panel. The disadvantage of these systems is that they are very deep and take up space in the front that could be used for other module inserts. This means that the mounting flanges in conventional systems are only used for mechanical attachment.

The object of the invention is to provide a fastening system of the type mentioned at the outset, in which display and/or operating elements such as LEDs, buttons and/or keyboards or the like as well as electronic components are integrated in the fastening system and which are suitable for use in plug-in and/or subrack systems.

This object is achieved with such a fastening system in that the fastening system consists of a profile, preferably of a specially shaped angle profile, into which display and/or operating elements covered with foil from the front and/or rear, such as foil buttons and/or keyboards with or without LEDs and with or without electronic components, are inserted and fastened in special recesses, whereby the cable feed for the display and/or operating elements goes via the angle profile into the plug-in and/or subrack systems and the angle profiles are fastened to the plug-in and/or subrack systems.

In a preferred embodiment of the fastening system with integrated display and control elements for plug-in and subrack systems, the fastening system consists of an extruded aluminum angle profile, in which one leg is used to fasten the plug-in and/or subrack system and the other leg of the angle is used for fastening in control cabinets or similar housings, and that there is a stiffener in the corner of the angle for cable feedthrough and that there is a stop rail on the angle profile which serves to improve the installation of the plug-in and subrack systems, with recesses being milled into the front of the fastening angle for installation in the control cabinet, into which foil-covered display and/or control elements and/or electronic components are installed, with the control elements preferably being inserted and fastened as foil-covered buttons and/or keyboards on a snap-on disk basis, and LEDs being inserted as display elements in the foil-covered keyboards. These display and/or control elements are controlled via an integrated cable that is routed into the plug-in and/or subrack systems via a recess in the stiffening of the angle profile.

In a further preferred embodiment, the milling is carried out on the back of the angle leg which is used for fastening to the control cabinet and the operating and/or display elements and/or electronic components are removed from the back of the

••VT·

Angled legs are installed, whereby the display and/or operating elements such as the LEDs are integrated on separate circuit boards or foils and can be covered on the front with a filter, whereby the filter can be a filter glass pane or a special foil and the operating elements are preferably designed as foil-covered buttons or keyboards on a circuit board basis.

The invention is explained in more detail using an embodiment shown in the drawings.

Figure 1 shows the fastening system, which consists of an extruded aluminum angle profile 1 and which has one leg for fastening the slide-in unit and subrack 2 and one leg for fastening the control cabinet 3, whereby the legs can be the same or different lengths, and between the legs on the inside of the angle profile a stiffener for the cable feedthrough 5 is integrated and on the leg for fastening the control cabinet 3 a stop rail 4 for the slide-in unit and subrack system is attached. The leg for fastening the control cabinet 3 has a milled recess 6 on the front for installing film-covered display elements 8 and film-covered operating elements on a snap disk basis 9. The display and operating elements 8, 9 can be installed individually or together. The connecting cable 11 for the display and operating elements for the slide-in unit and/or subrack system is led through the cable feedthrough 10 in the extruded aluminum angle profile 1.

Figure 2 shows the fastening system with rear milling 7 and with foil-covered control elements on a circuit board basis.

Figure 3 shows the aluminum angle extruded profile 1 in section, whereby the profile consists of the leg for the slide-in unit and subrack fastening 2 and the leg for the control cabinet fastening 3, which can have the same or different lengths and which have a stiffener for cable feedthrough 5 between the two legs and a stop rail 4 for the slide-in unit and subrack system is attached to the leg for the control cabinet fastening 3.
