Definitions

• the invention relates to a control cabinet with a control cabinet box, with several modules and with a mounting rail, the modules being fastened to the mounting rail.
• control cabinets In factories, as well as in factories and assembly halls, there are large, component-oriented control cabinets - usually in large numbers and at specified locations. A large number of electrical or electronic components and devices, which are necessary for supplying and controlling the various machines that are distributed in the workshop, are located in these control cabinets, which are often the size of a wardrobe.
• the electrical or electronic components and devices that are located in such a control cabinet include circuit breakers, power supplies, input / output modules, fuses, transformers and terminals for access wiring and for intermediate and outgoing routing.
• the individual electrical or electronic components and devices are arranged in a module-oriented manner in the control cabinet d. H. In one area of the control cabinet there are, for example, several input / output modules, in another area all circuit breakers.
• control cabinet is function block-oriented and modular, namely all the modules required for a machine and only these are installed.
• the control cabinet according to the invention thus only contains the number of modules that is necessary for its intended function.
• the modular design of the control cabinet enables optimal adaptation to the requirements of each individual machine. In addition, the space required is significantly less, and standardized control cabinet boxes can be used.
• modules are understood to mean all electrical or electronic components and devices which are typically also located in a classic control cabinet, such as, for example, power supplies, circuit breakers, input / output modules, fuses and transformers.
• the modules do not differ in their technical function from the electrical or electronic components and devices of a classic control cabinet, but only in their easier installation and removal.
• the individual modules are fastened in the control cabinet and connected to one another in such a way that they can be replaced without tools.
• the individual modules are electrically connected to each other by means of contact blades, so that cross-wiring is possible is not required. Due to the possibility of replacing each individual module or adding new modules, regardless of their position in the control cabinet, the provision of reserve modules is no longer necessary, so that the cost of materials can be considerably reduced.
• connection to other control cabinets and / or to machines and to a central energy supply and / or control takes place via a bus system.
• a bus system or the bus line then provides both the electrical supply to the individual control cabinets or the modules arranged therein, and also the data exchange between a central controller and the modules or between individual modules themselves.
• the possibilities of a bus system can also be used to self-diagnose the control cabinets.
• the switch cabinet according to the invention advantageously has internal potential and data routing with a continuous busbar. As a result, the individual modules are supplied with the required electrical power even if a single module is defective or is replaced.
• FIG. 1 shows an embodiment of a classic module-oriented control cabinet
• FIG. 2 shows an embodiment of a function block-oriented and modular control cabinet according to the invention
• 3 shows the control cabinet from FIG. 2, but without the control cabinet box
• Fig. 4 shows a second embodiment of a control cabinet according to the invention, also without a control cabinet box, and
• Fig. 5 shows a further embodiment of a control cabinet according to the invention, also without a control cabinet box.
• FIG. 1 shows a classic, module-oriented control cabinet 21 with a control cabinet box 22 and several electrical and electronic components and devices.
• the control cabinet 21 In the upper area of the control cabinet 21 there are a plurality of input / output modules 24, in the central area on the one hand a plurality of fuse elements 25, on the other hand a larger number of circuit breakers 26 and in the lower area devices 27 for fastening cable strands 28 which lead to the individual machines.
• a larger number of circuit breakers 26 on the other hand a larger number of circuit breakers 26 and in the lower area devices 27 for fastening cable strands 28 which lead to the individual machines.
• the control cabinet 21 shown in Fig. 1 serves to supply several machines, so that it takes up a relatively large amount of space. Due to the numerous cross-wiring between the components and devices as well as the terminals 29, 30 and 31, an expansion of the control cabinet 21 with additional components and devices or the replacement of faulty components and devices is connected with a great deal of effort. For this reason, when planning such a control cabinet 21, not only the current component and device requirements of the machines must be taken into account, but also replacement components and devices as well as supplementary components and devices must be installed in the control cabinet 21.
• Control cabinet 1 now shows a control cabinet 1 according to the invention, with a control cabinet box 2 and modules 3 arranged therein, which are fastened on a common mounting rail 4, which is not visible here.
• the individual modules 3 are visible from the outside behind the pane 5 of a hinged cover 6 and, as shown in FIG. 2, are accessible from the front when the cover 6 is folded up.
• the Control cabinet 1 is constructed in a function block-oriented manner, that is to say that it contains only the modules 3 which are necessary for the functioning of a machine.
• the control cabinet 1 contains a plurality of bus terminals 7 for connecting the control cabinet 1 to a bus system, a signal monitoring unit 8, a plurality of input / output modules 9, 10, a power supply unit 11 and two load relays 12.
• the input / output modules 9 differ from the input / output modules 10 only by a smaller number of connection channels.
• In the bottom of the control cabinet box 2 there are cable bushings 13 through which the lines of the machine belonging to the control cabinet 1 and lines for additional sensors and / or actuators can get into the interior of the control cabinet 1.
• the cable bushings 13 are also used for strain relief of the connected lines.
• the control cabinet 1 and in particular the control cabinet box 2 is designed in such a way that the control cabinet 1 corresponds at least to protection class IP 65.
• Fig. 3 shows the same control cabinet 1 as Fig. 2, but without control cabinet box 2.
• FIG. 4 Another embodiment of a control cabinet 1 according to the invention is shown in Fig. 4, also here without control cabinet box 2.
• the individual modules 3 are mounted on a common, hat-shaped mounting rail 4; they are preferably only snapped onto this mounting rail 4, so that individual modules 3m, as shown in FIG. 4, can be replaced without tools.
• the individual modules 3 are designed so that not only an edge module 3a or 3z, but any module 3m can be replaced. This is possible because the modules 3 can be snapped onto the mounting rail 4 from above, that is, they cannot simply be pushed on from the side.
• both the bus terminals 7 and the input / output modules 9 and 10 are characterized in that both the entire module 3 and only one module upper part 14 can be removed.
• the upper module part 14 serves as a plug module.
• the two-part design of bus terminals 7 and input / output modules 9, 10 makes it possible to replace a faulty bus terminal 7 or a defective input / output module 9 or 10. see without having to remove the wiring.
• the module upper part 14 is simply removed from the module lower part 15 when the wiring is fixed, for example by releasing a snap-in connection, and then the defective module lower part 15 is replaced.
• the upper module part 14 is then placed on the new lower module part 15.

• the interchangeability of the modules 3 and the module upper parts 14 is shown again.
• contact swords 16, which are located in the modules 3, can be seen in FIG. 5.
• the contact blades 16 establish the electrical connection between the individual modules 3.
• individual modules 3 have fields 17 for labeling and signaling the modules 3. These fields 17 can during the contacting of the modules 3 or the wiring of the module upper parts 14 either be completely removed from these or pivoted out of their display position shown in FIG. 5, so that free access to the modules 3 or the contacts of the module upper parts 14 is possible.
• the fields 17 are pivotally and detachably supported in corresponding recesses of the modules 3 with one of their two short sides.
• control cabinet 1 makes it clear that the modular structure and the simple, tool-free exchange of individual modules 3 make it easy to adapt each individual control cabinet 1 to any given situation.
• the coordination of the individual control cabinets 1 to a particular machine also makes it possible to carry out partial commissioning in a system composed of several machines or to carry out preliminary tests of the individual machines before the entire system is started up. This makes the setup and connection of an extensive system safer, easier and faster.
