The switchboard has a connection surface on which connection means for connecting electrical components, circuits, assemblies and / or switching modules are provided, as well as guide means for guiding electrical lines. The control panel has a solar module which is provided for supplying energy to the electrical circuits.

The devices known from the prior art have the particular disadvantage that they cannot be used without extensive preparatory work,

It is therefore the object of the present invention to provide a training system that can be used directly without preliminary work and that enables electrical circuit arrangements to be set up and tried out in a simple manner.

The task is a training system for setting up and trying out electrical circuit arrangements, comprising a plate which has an operating side and a mounting side and which carries several electrical functional units and several sockets, the electrical functional units being arranged so that they can be seen and / or operated from the operating side and where in the sockets can be plugged in from the operating side, and each functional unit is assigned at least two sockets, which are electrically connected to the respective functional unit on the assembly side.

The training system has the particular advantage that the electrical functional units are ready-installed for the construction of a switching arrangement and can only be electrically integrated into the switching arrangement by inserting the (preferably single-pole) plug of cables on an operating side.

In a particularly advantageous embodiment, the electrical functional units are mounted exclusively from the mounting side and can only be dismantled from the mounting side, in particular they can be dismantled in a non-destructive manner. Such a design has the very special advantage that the operating side can remain free of fastening means for fastening the electrical functional units, which considerably increases the clarity for the exercising person. In addition, such a design has the very special advantage that the connection sides of the electrical functional units can easily be protected from unauthorized access by the exercising persons, for example by enclosing the assembly side, which is described in detail below.

In general, fastening means can be provided by means of which the functional units are fastened to the plate, the fastening means preferably being arranged exclusively on the mounting side and / or being accessible from the mounting side. Analogously, further fastening means can be present by means of which the sockets are fastened to the plate, the further fastening means preferably likewise being arranged exclusively on the assembly side and / or being accessible from the assembly side.

In particular, it can advantageously be provided that at least one of the electrical functional units has an operating and / or display side which is arranged on the operating side of the plate. In a particularly advantageous embodiment, each of the electrical functional units has an operating and / or display side which is arranged on the operating side of the panel. Such a design has the very special advantage that the trainee can concentrate on the construction of the circuit arrangement by simply making plug connections and is not distracted by optical impressions of the electrical functional units that are not of use to him for this purpose.

In a particular embodiment, at least one of the electrical functional units has a connection side which is arranged on the mounting side of the plate. In particular, it can advantageously be provided that each of the electrical Functional units has a connection side which is arranged on the mounting side of the plate. In this way it is advantageously achieved that the electrical functional units on the assembly side can be electrically connected to the plug-in boxes and the operating side remains free of the electrical lines and assembly material required for this, which increases the clarity for the trainee.

In a particularly advantageous embodiment, the plate is part of a housing of the training system, the operating side being arranged on the outside of the housing and the mounting side being arranged inside the housing. With such an embodiment it is advantageously achieved that the exercisers cannot reach the assembly side and the electrical functional units are therefore protected from manipulation and / or damage. For this purpose, it can be provided, in particular, advantageously that the housing cannot be opened without tools and / or without being destroyed.

The housing can advantageously have a rear wall opposite the plate, which is transparent. In this way it is advantageously achieved that the exercisers can see how the electrical functional units within the exercise system are connected to the sockets and / or to other structural units of the exercise system. This makes it possible in particular that the trainees can not only set up and try out circuit arrangements, but also that the trainees can see how the electrical functional units used for the circuit arrangement are constructed and how they are connected during an installation. Nevertheless, the connection sides of the electrical functional units within the housing are effectively protected against manipulation.

The rear wall can be designed, for example, as a pane of glass, in particular made of hardened and / or strengthened glass, or as a plexiglass pane.

The housing can have a circumferential four-sided frame, in particular made of extruded profile parts, into which the plate is inserted on one side and the rear wall on the other side. Such a design is particularly robust.

The exercise system can particularly advantageously be designed and intended, in particular, to be set up on a horizontal installation surface, in particular on a table top, in such a way that the plate is oriented vertically. This enables an ergonomically advantageous posture for the practitioner when setting up circuit arrangements. In particular, this avoids having to bend forward in order to set up circuit arrangements.

In a particularly advantageous embodiment, the exercise system has at least one set-up fastening means, by means of which the exercise system can be fastened to a, in particular horizontal, set-up surface, in particular in a non-destructive manner. The mounting fastening means can for example have at least one suction cup. The suction cup can advantageously be designed in such a way that it can optionally be switched between a fastening state and a release state, for example with a switching lever. The suction cup can be part of a suction cup. As an alternative or in addition, the mounting fastening means can also have, for example, a table clamp, in particular for clamping to the edge of a table.

The set-up fastening means can advantageously be fastened directly or indirectly to the outside of the housing. In an advantageous embodiment, the relative position of the installation fastening means can be changed relative to the housing, for example in order to be able to adjust the installation height.

For example, the set-up fastening means can have a carrier which is fastened or can be fastened to the housing on the one hand and which on the other hand carries at least one suction cup or a table clamp or the like. For example, in order to be able to implement a height and / or lateral adjustment relative to the installation surface, the carrier can have an elongated hole through which a fastening screw runs, which is screwed into a thread of the housing.

The exercise system can advantageously have a handle, in particular on the top of the housing. The handle can advantageously be arranged, in particular, in such a way that the exercise system can be carried like a suitcase.

The exercise system preferably has a network connection element for connection to an electrical power network, in particular to a 230V power network. The mains connection element can be designed, for example, as a connection cable with a mains plug or as an IEC socket for plugging in a mains connection cable.

In a special, advantageous embodiment, the plate has at least two mains voltage sockets accessible from the operating side, to which a supply mains voltage, in particular an alternating voltage of 110 V or 220 V or 230 V or 240 V, is applied, in particular at an alternating voltage frequency of 50 Hz. The mains voltage supply sockets serve as a voltage source for the trainee, in particular an alternating voltage source, which he can integrate into his circuit arrangement by simply plugging in cable plugs. The training system preferably has a mains voltage control switch, by means of which at least the supply voltage present at the mains voltage supply sockets can be switched on and off.

There are no fundamental restrictions on the type of mains voltage. In particular, the exercise system can be adapted to the country-specific power grid. In a particularly safe embodiment, a system fuse and / or an emergency stop switch is connected between the mains connection element and at least one of the mains voltage supply sockets.

In the foremost way it can be provided that the plate has at least two low-voltage supply sockets accessible from the operating side, to which a direct voltage, in particular a direct voltage in the range from 1V to 50 V, in particular from 12 V, is applied. The low-voltage supply sockets serve as a low-voltage source for the trainee, in particular a DC voltage source, which he can integrate into his circuit arrangement by simply plugging in cable plugs. The exercise system preferably has a low-voltage control switch, by means of which at least the supply voltage applied to the low-voltage supply sockets can be switched on and off.

The training system can have at least one transformer that provides the DC voltage. A low-voltage system fuse and / or a microfuse can be connected between at least one of the low-voltage supply sockets and the transformer. This ensures that faulty circuit arrangements do not result in damage to the training system and, in particular, no damage to the transformer. The housing of the microfuse can advantageously be accessible from the operating side, so that the practitioner can also practice replacing the microfuse when it has melted.

In the forefront, at least one of the electrical functional units can be designed as a functional unit customary in residential building installations. In particular, several or all of the electrical functional units can be designed as functional units customary in residential building installations.

In a particularly advantageous embodiment, the low-voltage sockets differ from the mains voltage sockets in such a way that a low-voltage plug that can be inserted into a low-voltage socket cannot be inserted into a mains-voltage socket. In particular, it can advantageously be provided that the low-voltage sockets differ from the mains-voltage sockets in such a way that a mains plug that can be plugged into a mains-voltage socket cannot be inserted into a mains-voltage low-voltage socket. Such a system is particularly safe because it ensures that the electrical functional units intended for low voltage are not inadvertently connected to a mains voltage (for example 230 V alternating voltage) and that the electrical functional units intended for mains voltage (for example 230 V alternating voltage) are not accidentally connected to the low voltage ( e.g. 12 V DC voltage) can be connected.

1 shows schematically an embodiment of a training system according to the invention for setting up and trying out electrical circuit arrangements. The exercise system has a plate 1 on one operating side 2 and one (in the 1 and 2 not visible) mounting side 3rd having. The plate 1 carries several electrical functional units 4th , in particular in the form of switches or buttons or relays, and several sockets, namely low-voltage sockets 5 , in particular in the form of low-voltage supply sockets or low-voltage control lamp sockets or low-voltage button sockets, and (in particular 230 V AC) mains voltage sockets 6, in particular in the form of mains voltage supply sockets or mains voltage control lamp sockets or mains voltage switch sockets. For the sake of clarity, the reference symbols are used in the figure 4th , 6th and 6th in individual cases omitted if the component in question is a special version of an electrical functional unit, a low-voltage socket or a mains voltage socket, which is already provided with a specific reference number.

The electrical functional units 4th are from the operating side 2 arranged from visible and / or operable. In the sockets 4th can from the operating side 2 from (not shown), preferably single-pole, plugs, in particular each at the ends of cables 58 can be arranged to be inserted. The plugs can be designed, for example, as banana plugs and / or spring plugs and / or lamellar plugs. Each functional unit 4th are at least two sockets 5 , 6th assigned that on the assembly side 3rd to the respective functional unit 4th are electrically connected by means of assembly lines (not shown). In this way it enables one The practitioner can integrate a functional unit into a circuit arrangement by using the electrical functional units belonging to the circuit arrangement to be constructed 4th by plugging in the plugs of cables 58 into the associated sockets 5 , 6th , connects.

Each of the electrical functional units 4th has an operating and / or display page that is displayed on the in 1 visible operating side 2 the plate 1 is arranged. In this way it is possible for the trainee to use the functional units 4th can see and operate. For example, it is possible for the trainee to use a functional unit designed as a switch, which he can access by inserting cable plugs into the sockets assigned to the switch 5 , 6th , integrated into its circuit arrangement, to operate from the operating side. The switch can be, for example, a light switch such as is usually installed in living rooms, in particular in a flush-mounted construction.

The electrical functional units 4th also have a connection side, which, however, is advantageous on the assembly side 3rd is arranged and is therefore not accessible to the practitioner. In particular, the electrical connection contacts are the electrical functional units 4th not directly accessible to the practitioner. In this way it is advantageously achieved that the exerciser cannot manipulate the exercise system and also cannot damage it. The trainee can only use the functional units 4th thereby incorporate in his switching arrangement that he plugs the plugs of cables into the respective sockets assigned to the functional unit. However, he can install the functional units 4th advantageously not manipulate.

The electrical functional units 4th are by means of (in 3rd schematically shown) fastening means 56 on the assembly side 3rd on the plate 1 attached. As the mounting side 3rd (which is explained in detail below) is inaccessible to the trainee, the trainee can use the electrical functional units 4th do not dismantle yourself. The same applies to the sockets 5 , 6th that with other fasteners 57 on the assembly side 3rd on the plate 1 are attached.

As in the 2 and 3rd can be seen, the exercise system has a network connection element 7th , namely a connection cable 8th with a power plug 9 by means of which the exercise system can be connected to a public power grid, in particular to a 230V power grid. It is a system backup, namely a system backup machine 10 , available, which can be designed, for example, as a residual current circuit breaker B16A, and through which the training system is protected. This has the particular advantage that the voltage supply of the exercise system is automatically switched off immediately if the exerciser should inadvertently set up a circuit arrangement that is defective. In this way, it is effectively avoided that the exercise system is damaged and that a fuse arranged in the public mains circuit to which the exercise system is connected reacts or the public mains circuit is damaged, for example by a short circuit. In addition, the system backup is by means of 10 advantageously avoided that the practitioner is exposed to an electric shock if he makes mistakes.

The exercise system has an emergency stop switch 11 by means of which the exercise system as a whole can be quickly disconnected from the mains voltage. The emergency stop switch preferably has an operating button which is highlighted in color (in particular in red) and which can be hit to switch off the mains voltage supply if necessary. In particular, the emergency stop switch 11 be designed in such a way that after actuation it can only be returned to the switched-on position with the aid of a key. In this way it is possible, for example, that only the trainer can switch on the exercise system again after he has checked that the circuit arrangement set up by the trainees is free of errors.

The training system points from the operating side 1 from accessible mains voltage supply sockets 12th to which a mains supply voltage, for example 230 V, is present. Specifically, is a mains voltage supply socket 12th to which the phase is applied and which is marked with "L". In addition, there is another mains voltage supply socket 12th available, which is connected to the neutral conductor and which is marked with "N". In addition, there is another mains voltage supply socket 12th present, which is permanently earthed and which is marked with "PE".

The exercise system also has a transformer 43 on, the one on the low-voltage supply sockets 14th provides applied low voltage. Between at least one of the low-voltage supply sockets 14th and the transformer 43 is a 12V system fuse 44 and a microfuse 45 switched. In this way it is ensured that faulty circuit arrangements do not result in damage to the training system and in particular not to damage to the transformer 43 comes. The housing of the microfuse 45 is from the operating side 2 accessible so that the practitioner can also practice fine-tuning 45 to be replaced if necessary.

The exercise system has a mains voltage control switch 13th on, by means of which at least the one on the mains voltage supply socket 12th , which is marked with "L", the applied supply voltage can be switched on and off.

The plate 1 points from the operating side 2 from accessible low-voltage supply sockets 14th to which a direct voltage, in particular a direct voltage in the range from 1 V to 50 V, preferably from 12 V, is applied. In addition, there is a low voltage control switch 15th available, by means of which the on the low-voltage supply sockets 14th applied voltage can be switched on and off.

The trainee advantageously has the option of changing his circuit arrangement when the mains voltage control switch is switched off 13th and switched off low voltage control switch 15th build up first, whereby he can be sure that all electrical functional elements 4th stay tension-free. Then he can switch on the mains voltage control switch 13th and / or the low voltage control switch 15th Electrically connect its circuit arrangement and try it out.

The exercise system has low voltage control lights 16 on the assigned low-voltage control lamp sockets 17th can be integrated into a circuit arrangement.

The exercise system also has low voltage pushbuttons 18th on that via low-voltage pushbutton sockets 19th can be integrated into a circuit arrangement.

The exercise system also has other low-voltage buttons 20th which are different in color from the low-voltage buttons 18th differentiate and the assigned additional low-voltage pushbutton sockets 21 can be integrated into a circuit arrangement.

The exercise system also has a low voltage LED indicator light 22nd on, which is designated with H1 and which has low-voltage LED control lamp sockets 23 can be integrated into a circuit arrangement. There are also additional LED indicator lights 24 available that can be operated with mains voltage (e.g. 230 V) and that have the associated mains voltage control lamp sockets 25th can be integrated into a circuit arrangement.

The exercise system has a first relay 26th on, which can be connected (via the low-voltage sockets + A1 and -A2) to a low-voltage control circuit of the circuit arrangement to be set up and that via relay mains voltage sockets 27 can be integrated into a load circuit of the circuit arrangement to be built.

The exercise system also has a second relay 28 on, which can be integrated into a (preferably 230 V) AC mains voltage control circuit of the circuit arrangement to be set up via relay mains voltage sockets. The second relay 28 can be via additional relay mains voltage sockets 29 be integrated into the load circuit of a circuit arrangement.

The exercise system also has a third relay 30th with a self-holding function via AC relay mains voltage sockets 31 into an alternating current control circuit (in particular 230 V) of a circuit arrangement and via relay mains voltage sockets 32 can be integrated into a load circuit of the circuit arrangement.

The exercise system also has a staircase timer 33 on the staircase timer sockets 34 can be integrated into a control circuit of a circuit arrangement to be set up and via staircase timer switch mains voltage sockets 35 can be integrated into a load circuit of the circuit arrangement.

The exercise system also has several bell buttons 36 each via two mains voltage sockets 6th can be integrated into a circuit arrangement.

The exercise system also has two off-control toggle switches 37 on. In addition, the system has two buttons 38 on. The system also has two cross switches 39 on. The system also has a series switch 40 with two rocker switches. In addition, the system has a double toggle switch 41 with two rocker switches. In addition, the system has a protective contact socket (especially common in house installations) 42 on.

The low-voltage sockets 5 differ from the mains voltage sockets 6th such that one in a low voltage socket 5 Insertable low-voltage plug not in a mains voltage socket 6th can be inserted and vice versa. This makes the exercise system particularly safe because it is guaranteed that the electrical functional units intended for low voltage 4th not accidentally connected to a mains voltage (for example 230 V alternating voltage) and the electrical functional units provided for mains voltage (for example 230 V alternating voltage) 4th cannot be accidentally connected to the low voltage (e.g. 12 V DC voltage).

The plate 1 can advantageously be designed as a metal plate, in particular as a brushed steel plate. Such a design is particularly robust.

Like in particular the 3rd shows is the plate 1 Part of a housing 46 , with the operating side 2 on the outside of the case 46 is arranged and wherein the mounting side 3rd is arranged inside the housing. The case 46 assigns one of the plate 1 opposite rear wall 47 on, which is preferably made transparent. In this way it is advantageously achieved that the trainees can see how the electrical functional units 4th within the exercise system to the sockets 5 , 6th and / or are connected to other components of the training system. This makes it possible in particular that the trainees can not only set up and try out circuit arrangements, but also that the trainees can see how the electrical functional units used for the circuit arrangement 4th and how they are connected during an installation. Nevertheless, the exercise system has the particular advantage that the electrical functional units 4th inside the case 46 are protected and in this respect cannot be manipulated by the practitioner. This has the very special advantage that the exercisers are protected from electric shock and, moreover, the advantage that the exercise system is protected from damage.

The case 46 can have a surrounding four-sided frame 48 have, in one side of the plate 1 and on the other side the back wall 47 is used. Such a design is particularly robust.

The exercise system is designed and intended to be placed on a horizontal surface 49 to be placed in such a way that the plate 1 oriented vertically. This enables an ergonomically advantageous posture for the practitioner when setting up circuit arrangements. In particular, this avoids having to bend forward in order to set up circuit arrangements.

The exercise system has a plurality of set-up fasteners 50 on, by means of which the exercise system, in particular detachable again in a non-destructive manner, on the installation surface 49 can be attached. In the illustrated embodiment, the stand-up fastening means 50 multiple suction cups 51 on, each by means of a toggle lever 52 optionally in a suction position (in which the exercise system on the installation surface 49 is set) or in a release position (in which the exercise system is not on the installation surface 49 is fixed) can be transferred. The suction cups 51 can be designed similarly to the suction cups of suction holders that are used to transport glass panes. Two suction cups each 51 are on a carrier 53 attached, the elongated holes 54 having. Through the elongated holes 54 are fastening screws 55 led that into the housing 46 are screwed in. That way is the carrier 53 including the mounting fasteners attached to it 50 adjustable on the housing 46 attached or attachable. Through the elongated holes 54 it is possible to adjust the installation position of the housing 46 with regard to the installation height relative to the installation area 49 to vary. There are two carriers in total 53 , which are screwed on the side faces and on which two each to the front and back over the housing 46 protruding suction cups 51 are attached.

At the top of the case 46 is a handle 55 attached, which makes it possible to carry the entire exercise system like a suitcase.

The case 46 can advantageously have a length of 100 cm, a height of 60 cm and a depth of 12 cm, for example.

4th shows an embodiment of the training system according to the invention, in which a very simple circuit arrangement is implemented as an example, into which the low-voltage supply sockets 14th , the low-voltage button 18th and the low voltage indicator light 16 Are involved by the low voltage sockets 17th , 19th as well as the low-voltage supply sockets 14th by means of cables 58 that have matching low-voltage plugs at the end have been electrically connected.

5 shows the circuit diagram relating to the provision of the mains voltage supply voltage at the mains voltage supply sockets 12th and a low voltage on the low voltage supply sockets 14th . However, the invention is not restricted to this exemplary circuit. Rather, it is possible to install other components and / or to choose a different interconnection. For example, it is also possible to use a switched-mode power supply instead of the transformer 43 possible. For example, it is also possible to use other types of fuses and / or switches.
