Description

The invention relates to a functional module for coupling to an electrical/electronic switching device for building installation technology located in an installation box, the electrical/electronic switching device for intended use having defined cabling, for example for controlling lights, blinds or sockets, which is connected to the functional module by means of an actuating element, in particular an upper part, of the electrical/electronic switching device and a remote control, for example a radio transmitter, can be influenced, the functional module having electrical/electronic components required for its function on at least one electrical circuit board, and the functional module having at least one connected to the electrical circuit board connected interface on the function module side, which is suitable for interaction with an interface on the switching device side, via which interfaces actuators, for example lights or blinds, can be controlled, or sensors, for example push-button sensors, can be evaluated, and as a result of which a control signal is transmitted between the function module and the electrical/electronic switching device , wherein the function module-side interface has an output channel for providing the control signal, which can be influenced both via the remote control and via the actuating element.

In addition, the invention relates to an electrical/electronic switching device for building installation technology with a base part which is designed to connect the defined cabling required for the intended use of the electrical/electronic switching device, for example for controlling a lamp, and wherein the electrical/electronic switching device is -Local actuation has an actuating element, in particular an upper part.

Furthermore, the invention relates to an arrangement comprising such a function module, which is coupled to such an electrical/electronic switching device.

Furthermore, the invention relates to a method for installing such a functional module on such an electrical/electronic switching device.

Electrical/electronic switching devices are used, for example, to operate lights (www.jung-group.com/de-DE/Wippschalter-Universal-Aus-Swapping-10-AX-250-V/506-U}. Electrical ones are also known /electronic switching devices that are suitable for controlling a blind, external venetian blind or similar (www.jung-group.com/de-DE/Jalousie-Wippschalter-10-AX-250-V-1-pol.-1-antrieb/ 509-VU). For this purpose, the electrical/electronic switching device is regularly installed and fixed as an insert in an installation box, while an actuating element is provided for actuation, which is equipped, for example, with an upper part. The upper part, also regularly referred to as an attachment, can be in different Designs can be available. Such electrical/electronic switching devices fulfill their purpose as soon as this consists of performing a desired function (switching on the light or moving the blinds) based on local actuation. Depending on the application, such an electrical/electronic switching device can be used as a button or switch be executed. Functional modules for such electrical/electronic switching devices in building installation technology are usually intended to control actuators and/or sensors via their independent channels, both via a switch or button and remotely via an external device, for example a mobile terminal device, via radio signal. In this respect, the function modules are intended to expand the function of electrical/electronic switching devices, for example a button or switch, by assigning additional functions to the electrical/electronic switching device and optionally also enabling remote actuation of the electrical/electronic switching device or the actuators connected to it, for example the Dimming of lights by operating the electrical/electronic switching device or by operating an application on a mobile device.

A function module corresponding to the preamble of the main claim is known from the prior art, for example according to the website nexentro.de. Such a function module is designed for building installation technology and is suitable for coupling to an electrical/electronic switching device for building installation technology that is located in an installation box. In this case, the electrical/electronic switching device has a defined cabling for the intended use. In any case, such cabling includes the connection to the L contact or the phase, as well as a switched output (a neutral conductor and/or other control lines, particularly in the case of shutter actuators, can also be provided). In the context of this invention, the term “defined cabling” is to be understood as meaning cabling that is given/defined by the cable material specified in the installation box. It would be a change in the defined wiring if the wiring were to be supplemented with new cables, for example between a function module and the electrical/electronic switching device.

The functional module can be influenced by means of an actuating element of the electrical/electronic switching device and a remote control. For this purpose, the function module has the electrical/electronic components required for the function on at least one electrical printed circuit board. Furthermore, the functional module has at least one functional module-side interface connected to the electrical printed circuit board, which is usually designed as a screw terminal, which is suitable for interaction with an interface on the switching device side. Actuators, such as lights or blinds, can be controlled via these interfaces, or sensors, such as touch sensors, can be evaluated. A control signal is transmitted between the functional module and the electrical/electronic switching device through these interfaces, with the functional module-side interface having an output channel for providing the control signal, which can be influenced both via the remote control and via the actuating element. Installing the function modules on electrical/electronic switching devices makes these conventional electrical/electronic switching devices “smart” by adding additional functions such as remote control, dimming the light or the like to the electrical/electronic switching device.

Previously known electrical/electronic switching devices used in building installation technology include a base part which is designed to connect the defined cabling required for the intended use of the electrical/electronic switching device, for example for controlling a lamp. Furthermore, the electrical/electronic switching device has an actuating element, in particular an upper part, for on-site actuation.

However, in practice there is a significant obstacle for the broad masses of users to connect a function module to an electrical/electronic switching device:

The accommodation of a function module and the associated cable material in the installation box is sometimes very challenging for reasons of space; In addition, the large number of new cabling that needs to be created also represents a problem that essentially only experts in electrical engineering dare to solve. In practice, retrofitting a function module to an electrical/electronic switching device is therefore largely reserved for electrical experts. This means that the subsequent function expansion of an electrical/electronic switching device is undesirably reserved for only a fraction of potentially interested users. In addition, the previously known function modules make considerable demands on the depth of the installation box via their interface, which is usually designed as a screw terminal, so that installation in so-called flat installation boxes, at least in installation boxes with a depth of less than 40 mm, is not feasible.

More generic function modules are both from DE 20 2015 102 332 U1 as well as off DE 103 01 014 A1 However, which require a high installation effort and a high depth of the installation box.

Proceeding from this discussed prior art, the invention is based on the object of creating a functional module for coupling to an electrical/electronic switching device in building installation technology or an electrical/electronic switching device that allows a functional module to be coupled, the installation effort and the claims to the depth of the installation box is significantly reduced, so that the hurdle of installation, especially for users who have little knowledge of electrical engineering, is lowered. Furthermore, this simplified coupling of a functional module to existing electrical/electronic switching devices should be possible in a retrofitting process, for example if it turns out that the electrical/electronic switching devices are to be expanded with functional modules and/or the financial scope for this will only be available after a certain period of time.

This function-module-related task is solved by a function module according to claim 1.

This switching device-related problem is solved by an electrical/electronic switching device according to claim 8.

The core idea of the invention is that the function module and its function module-side interface are designed in such a way that when the function module is coupled to the interface of the electrical/electronic switching device, the existing, defined cabling of the electrical/electronic switching device can be used as intended, for example for controlling lights or blinds, does not have to be changed in order to achieve a coupling of the function module to the electrical/electronic switching device provided for this purpose. In particular, no new wiring needs to be established between the functional module and the electrical/electronic switching device, which is consistently the case with previously known functional modules or electrical/electronic switching devices. Therefore the pair of a functional module according to the invention and an electrical/electronic switching device according to the invention represents a particularly attractive possibility of subsequently expanding existing building system technology in a modular and simple functional manner. The preservation of the cabling of the electrical/electronic switching device according to the invention represents an immense advantage over previously known electrical/electronic switching devices whose cabling must be supplemented in order to connect a function module, usually via screw terminals into which further cabling is clamped. This not only simplifies the installation, but also significantly reduces the space required in the installation box, since the wiring is not changed. In addition, this mutual coordination of the functional module according to the invention and the electrical/electronic switching device according to the invention allows the installation space requirement of such a functional module to be roughly halved due to the omission of the screw terminal (otherwise additional cabling would have to be provided to connect the functional module, which is precisely excluded according to the invention). can be, since the screw terminals make up the main part of the installation depth in previously known function modules. In particular, the screw terminals take up a multiple of the installation depth of a printed circuit board due to their design.

A functional module according to the invention can be influenced by means of an actuating element, in particular an upper part, of the electrical/electronic switching device to which the functional module can be coupled, and a remote control. On at least one electrical printed circuit board, the function module includes the electrical/electronic components required for the function, for example a dimming actuator, a blind actuator or a switching actuator. Furthermore, the function module has an interface on the function module side that is connected to the electrical printed circuit board and is suitable for interaction with an interface on the switching device side. Actuators, for example lights or blinds, can then be controlled via the two interacting interfaces, or sensors, for example touch sensors, can be evaluated. A control signal is transmitted between the functional module and the electrical/electronic switching device, with the functional module-side interface having an output channel for providing the control signal, which can be influenced both via the remote control and via the actuating element.

According to a particularly preferred embodiment of the invention, the functional module-side interface is designed in the manner of a plug or a plug receptacle. It goes without saying that in such a case the interface on the switching device side is designed to be complementary, ie as a connector receptacle or as a connector. This avoids using cabling, in particular a screw terminal on the function module. In particular, this refinement allows the interfaces involved to be implemented in a cost-effective manner.

According to a particularly preferred embodiment of the invention, both the switching device side and the function module side interface are designed as flat (male) contact points. In the context of the invention, plane contact points are to be understood as interfaces that have contact points that protrude by a maximum of 10 mm, ie: male contact points. In contrast to an embodiment of the function module-side interface in the manner of a plug or a plug socket, the described embodiment as a flat (male) contacting point requires less installation space (since a plug or plug socket solution requires a certain installation depth due to the design). In addition, the risk of mechanical damage to interfaces designed as planar contacting points during assembly is significantly reduced, so that, for example, bending or breaking off a plug-like interface is effectively avoided. Furthermore, the deliberate avoidance of plug receptacle-like depressions is also accompanied by the avoidance of particles (dust, plaster or the like) which would otherwise penetrate into the plug receptacle-like depressions. This aspect is of particular importance in the event of a later retrofitting of a function module on the electrical/electronic switching device.

According to an embodiment of the invention according to the invention, which enables a particularly simple, space-saving and cost-effective implementation, the function module has at least two contacts on its function-module-side interface. A first contact is connected to the L contact of the electrical/electronic switching device at a first connection point via a corresponding first contact of the interface on the switching device side. Such a design of the first contact enables the functional module to be supplied with energy in a particularly simple manner, so that a complex battery supply, which would also cause additional installation height, is no longer necessary. In addition, the functional module has a switching state evaluation device, so that the actuation of the actuating element or a switching process is detected. This is required so that the function module can is to record the switching process and send a corresponding control signal.

Furthermore, a second contact of the function module is also connected to the L contact (or L path) of the electrical/electronic switching device at a second connection point via a corresponding second contact of the interface on the switching device side, with the second contact of the interface on the switching device side being designed as a separable contact is. This separable contact of the switching device-side interface can be influenced by a control signal from the function module, in particular by the separable contact being closed when a (on) switching request is detected or the separable contact being opened when a (off) switching request is detected.

With such a design of the electronics, the switch or button of the electrical/electronic switching device is intelligently manipulated in such a way that in any case the functional module based on the on-site operation detected by the switching state evaluation device or by operation via remote control sends control signal. In this respect, it is even conceivable that the electrical/electronic switching device is designed without an actual switch if operation without a functional module is to be provided (for example in the case of a direct installation of an electrical/electronic switching device and a functional module). The electrical/electronic switching device is then primarily used to accommodate the wiring and an actuating element for on-site operation without a switch or button being required in the electrical/electronic switching device, which would reduce the costs and the space requirement .

In the embodiment according to the invention described above, the switching state evaluation device comprises a third contact which is also connected to the L contact of the electrical/electronic switching device at a third connection point via a third contact corresponding thereto of the interface on the switching device side. In this case, the third connection point is arranged between the first and the second connection point. In this refinement, the switching state evaluation device taps off the logical switching state via the third contact, since a voltage is present at the third connection point when the switch between the first and third connection points is closed. This makes it possible to detect an on-site operation in a particularly simple manner.

According to a particularly preferred embodiment of the functional module according to the invention, this includes a dimming actuator for dimming dimmable lamps or a switching actuator or a blinds actuator for controlling blinds or a touch sensor for actuating an electrical device.

In a further development of the functional module according to the invention, this has a sensor for detecting a magnetic field. The electrical/electronic switching device has at least one magnet, which changes its position when the actuating element is actuated. Furthermore, the function module has an evaluation unit for evaluating the change in the magnetic field, which evaluation unit serves as a switching state evaluation device. It is preferred if the evaluation unit identifies the electrical/electronic switching device as a switch or button, so that correct control of the connected actuator is ensured, since a switch, in contrast to a button, does not spring back into its original position.

With regard to the electrical/electronic switching device of building installation technology that interacts with the functional module according to the invention, the invention relates to such a device with a base part that is designed to connect the defined cabling required for the intended use of the electrical/electronic switching device, for example for controlling a lamp. Such wiring always includes an L-contact - both as an input and as an output from the electrical/electronic switching device. The electrical/electronic switching device has an actuating element, in particular an upper part, for on-site actuation. This electrical/electronic switching device is characterized in that the base part has an interface on the switching device side for coupling a functional module according to the invention, the functional module with its functional module-side interface being designed in such a way that when the functional module is coupled via the interfaces to the electrical/electronic switching device, the defined Cabling of the electrical / electronic switching device remains unchanged. In particular, no wiring needs to be changed or added. The functional module can then be influenced by means of an actuating element and remote control in order to influence actuators connected to the electrical/electronic switching device. Such an electrical/electronic switching device advantageously makes it particularly easy to couple a functional module for functional expansion, for example for dimming lights and/or remote control via a radio transmitter arranged in the functional module can be carried out and the requirement for the installation depth is noticeably reduced, since a screw terminal of the function module or the cabling connected to it is not used at the moment. In particular, such an electrical/electronic switching device represents the optimal preparation for subsequent, simple retrofitting of a functional module, since no additional cabling needs to be installed and it is not necessary to replace the electrical/electronic switching device according to the invention.

According to a particularly preferred embodiment of the electrical/electronic switching device according to the invention, the electrical/electronic switching device has at least two contacts on its switching device-side interface, with a first contact being connected to the L-contact of the electrical/electronic switching device at a first connection point, with a second Contact is also connected to the L-contact of the electrical / electronic switching device at a second connection point. The second contact of the interface on the switching device side is designed as a separable contact, the separable contact of the interface on the switching device side being able to be influenced by a control signal from the functional module, and the functional module having a switching state evaluation device.

In a further development of this embodiment of the electrical/electronic switching device according to the invention described above, the switching state evaluation device has a third contact which is also connected to the L contact of the electrical/electronic switching device at a third connection point, the third connection point being between the first and the second Connection point is and a switch between the first connection point and the third connection point is located.

According to a particularly preferred embodiment of the electrical/electronic switching device according to the invention, the electrical/electronic switching device has a neutral conductor contact at its interface on the switching device side, this neutral conductor contact being actively connected to the corresponding neutral conductor contact of a functional module according to the invention. The neutral conductor located in the installation box - required for certain applications, for example for connecting a switch actuator - is connected to this neutral conductor contact. Such a connection can advantageously be achieved by the electrical/electronic switching device having a receptacle into which a neutral conductor is to be inserted, the electrical/electronic switching device then contacting this neutral conductor with its neutral conductor contact with its interface on the switching device side. Alternatively, the neutral conductor contacts the function module-side interface of the neutral conductor contact. The implementation of a neutral conductor contact described above is particularly suitable if the functional module coupled to the electrical/electronic switching device represents a switching actuator. The defined cabling is also retained in these embodiments, since a neutral conductor is already present in the installation box and no additional cables, which are typically short, have to be installed.

In a further development of the electrical/electronic switching device according to the invention, a holding device is connected to the base part, which holds the electrical/electronic switching device in place in an installation socket, in particular by means of screw claws that can be spread apart. In this case, the holding device provides a receptacle for the functional module, into which the functional module can be countersunk to minimize the installation depth. This is possible in particular because the functional module according to the invention does not require a screw terminal, so that the electrical printed circuit board of the functional module can be dimensioned sufficiently small to allow the functional module to be inserted countersunk into the receptacle.

For particularly simple fixing of the functional module on the electrical/electronic switching device according to the invention, the base part has fixing means for fixing the functional module that can be coupled. These fixing means can be designed as latching lugs or other structures that generate a holding force. This preferably even enables tool-free installation.

Furthermore, the invention relates to an arrangement comprising a functional module according to the invention and an electrical/electronic switching device according to the invention.

Furthermore, the invention relates to a method for installing a function module according to the invention on an electrical/electronic switching device according to the invention, comprising the steps:

• - Release of the electrical/electronic switching device fixed to an installation socket of the building installation technology and having a defined cabling,
• - Coupling of the functional module to the electrical/electronic switching device via the functional module-side and switching device-side interface without changing the wiring of the electrical/electronic switching device and
• - Defining the arrangement formed from the function module and the electrical/electronic switching device on the installation box of the building installation technology.

The method is characterized by particularly few method steps that are easy to carry out, in particular in comparison to conventional retrofitting of electrical/electronic switching devices with function modules.

1 shows a cross-section of a conventional electrical/electronic switching device S, which is fixed in an installation box D of the building installation technology. The definition is shown here using expanding claws K. These can be spread out by turning the setting means EM of the holding device HV using a screwdriver until the spreading claw K comes into operative contact with the installation box D. The electrical/electronic switching device S has an actuating element, which is designed here as an upper part O placed on an upper part receptacle OA. also in 1 wiring is shown. This includes an L contact that is connected to the electrical/electronic switching device S and a switched L contact that serves as the output of the electrical/electronic switching device S, for example to lead to a lamp.

In 2 shows a schematic representation of an electrical/electronic switching device S and a functional module F from the prior art in a plan view. The individual components are shown offset from one another for the sake of clarity, while the arrangement in the installation box D is one behind the other.

In this case, such conventional function modules have a screw terminal to which cabling is connected, in particular the electrical/electronic switching device S, but also cable material that comes out of the wall, for example an L contact (phase), regularly also an N contact ( outer conductor). In the present case, the function module F is designed as a dimming actuator DA. The output of the function module F is a control line SL, which leads to a dimmable lamp, not shown. Such a previously known function module F regularly also has a remote control, in particular a radio transmitter, so that actuation via the upper part O or via radio is possible. The disadvantage here, however, is that a large number of cables must also be connected if the electrical/electronic switching device S is to be provided with a functional module F. It is not only the pure connection of the cabling that poses a challenge, but also the accommodation of the cable material and the function module F in the installation box D.

The remedy for this problem is the in 3 The electrical/electronic switching device S according to the invention shown in cross section. This has a base part that is designed to connect the defined cabling required for the intended use of the electrical/electronic switching device S, for example for controlling a lamp. The electrical/electronic switching device S has an actuating element, in particular an upper part O, for on-site actuation. Furthermore, the base part has an interface CS on the switching device side for coupling a function module F according to the invention (for the sake of clarity, only 4 shown), the function module F with its function module-side interface CF being designed in such a way that when the function module F is coupled to the electrical/electronic switching device S via the interfaces CF, CS, the defined wiring of the electrical/electronic switching device S remains unchanged (Note: compare the wiring in 1 and 3 ). In this case, the functional module F can be influenced both by means of the actuating element and by remote control. It goes without saying that the function module F has a corresponding radio receiver for this purpose.

The advantageous, because it is particularly simple, coupling of a functional module F according to the invention to the electrical/electronic switching device S according to the invention is in 4 , also shown in a cross-sectional view. It can be seen how the two interfaces CS, CF, the interface CS on the switching device side and the interface CF on the function module side, are connected to one another. The functional module F can be held via the interfaces CF, CS, in particular if they are designed in the manner of a plug and a plug receptacle, and/or via fixing means FM for fixing the functional module F that can be coupled. Furthermore shows 4 a holding device HV of the base part, which fixes the electrical/electronic switching device S, in particular by spreadable screw claws K, in the installation box D, the holding device HV providing a receptacle A for the functional module F. The function module F can be inserted into this receptacle A in a countersinking manner in order to minimize the installation depth T. On the one hand, this makes it possible to hold a holding device HV at a geometrically optimal point (such a holding device HV regularly has screw bosses that require a certain extension in the installation direction so that the expanding claws K engage in the installation box D and not the plaster) and on the other hand a volume in the form of the receptacle A for accommodating the functional module F is created. This positioning is made possible in particular by dispensing with screw terminals and the cabling connected to them, since this reduces the volume of installation space and also no side that is freely accessible for the connections of the screw terminals has to be provided. This makes the design extremely compact, so that accommodation in so-called flat installation boxes D, which regularly allow a maximum installation depth of a maximum of 40mm or even a maximum of 32mm, is possible.

In 5 shown. In the 5 The arrangement shown comprising a function module F and an electrical/electronic switching device S according to the invention is characterized in that the function module F has at least two contacts KF1, KF2 on its function-module-side interface CF. A first contact KF1 is connected to the L contact of the electrical/electronic switching device S at a first connection point A1 via a corresponding first contact KS1 of the interface CS on the switching device side. Such a configuration of the first contact enables the functional module F to be supplied with energy in a particularly simple manner, so that a complex battery supply is no longer necessary. In addition, the functional module F has a switching status evaluation device, so that the actuation of the actuating element or a switching process is detected. This is necessary so that the function module F is able to detect the switching process and issue a corresponding control signal.

Furthermore, a second contact KF2 of the function module F is also connected to the L contact of the electrical/electronic switching device S at a second connection point A2 via a corresponding second contact KS2 of the switching device-side interface S, with the second contact KS2 of the switching device-side interface CS being a separable contact is made. This separable contact of the interface CS on the switching device side can be influenced by a control signal from the function module F, in particular by the separable contact being closed when a (on) switching request is detected or the separable contact being opened when a (off) switching request is detected.

Furthermore, the 5 The arrangement shown has a third contact KF3 of the function module F, which is also connected to the L contact of the electrical/electronic switching device S at a third connection point A3 via a third contact KS3 corresponding thereto of the interface CS on the switching device side. In this case, the third connection point A3 is arranged between the first connection point A1 and the second connection point A2. As a result, the switching state evaluation device picks up the logical switching state via the third contact KF3, since a voltage is present at the third connection point A3 when the switch between the first connection point A1 and the third connection point A3 is closed. This makes it possible to detect on-site actuation and remote control via radio in a particularly simple manner. If the function module is an actuator for blind control or another multi-channel actuator (e.g. a two-channel switch), the interface with respect to the third contact KS3, KF3 is double or multiple, so that each actuation of the corresponding channel can be detected.
