Description

The present invention relates to a device for arrangement on current busbars, having a switching device and an electronic module. The switching device can in particular be a fuse strip or switch disconnector strip for low-voltage, high-performance (NH) fuses.

Increasingly high demands are being placed on switching devices that are typically used for power distribution. In particular, it is provided that switching devices are equipped with electronic components for measuring and processing measured values, for example to permanently monitor or measure all current and voltage-related data and/or to monitor or monitor the electrical fuses installed in the switching device and their status To overgrow switching state of the switching device.

From the DE 297 05 224 U1 a device for arranging busbars is known, this device having an NH fuse or NH fused switch and a device carrier strip. Furthermore, the device has a converter wired to a measured value recorder or a terminal or plug strip. The separate device carrier strip takes the The converter and the terminal or plug strip or the measured value recorder are assigned to the device carrier strip. The equipment carrier rail is arranged between the busbars and the switching device, the switching device being placed on the equipment carrier rail, as a result of which the device has a greater installation space requirement in the vertical direction than the switching device itself. A separate sensor can be mounted on the device.

the EP 2 053 627 A2 relates to an NH fuse switch disconnector having a housing with a bottom surface and at least one feed contact that projects beyond the bottom surface, and having a current transformer surrounding the feed contact.

The object of the present invention is to create a device for arranging on busbars with a switching device and an electronic module, which is characterized by particularly simple handling and also by a particularly small space requirement. Furthermore, the object of the invention is to create a device with a switching device and an electronic module, in which a particularly simple and rapid exchange of components of the electronic module is made possible. These objects are achieved by a device having the features of patent claim 1. Advantageous embodiments are the subject matter of the dependent claims.

The device according to the invention for arranging on busbars has a switching device, also referred to as a switching device, and an electronic module. The switching device is in particular a fuse strip or switch disconnector strip for NH fuses. The switching device according to the invention is in particular a switching device for arrangement on a so-called 100 mm busbar system, in which the central axes of adjacent current busbars have a distance of 100 mm. However, it is also entirely conceivable to use such a device on busbars with a distance of less than or greater than 100 mm, for example on busbars with a distance of 185 mm, with appropriate adapters being able to be used for this purpose.

The switching device of the device according to the invention has a front side which is to be turned away from the busbars. The front side is therefore that side of the switching device that faces an operator of the switching device. In the state connected to the busbars, the operator can access the front side of the switching device, whereas the rear side of the switching device, which is opposite the front side and faces the busbar system, is not accessible to the operator. The switching device also has a housing and fuse holders arranged in a longitudinal direction of the switching device for accommodating fuses, preferably on the front, with a pair of contacts being assigned to the respective fuse holder. One contact of the contact pair is connected to an input current conductor and the other contact of the contact pair is connected to an outgoing current conductor. The electronics module has a housing and a sensor component for voltage and/or current and/or energy measurement. Furthermore, the electronics module has a further processing component for detecting and further processing an output signal or a preprocessed output signal of the sensor component and a transfer component for forwarding the output signal or preprocessing the output signal and forwarding the preprocessed output signal to the further processing component. The housing of the electronics module has a first housing section, a second housing section and a third housing section. The sensor component is mounted in the first housing section, the transfer component is mounted in the second housing section and the further processing component is mounted in the third housing section. The switching device and the electronic module are detachably connected to one another. The first housing section of the electronic module is arranged on a rear side of the switching device facing away from the front side and the second housing section and the third housing section of the electronic module protrude in the longitudinal direction of the switching device with respect to the switching device.

The advantage is that the electronics module can be equipped with the components or pre-assembled independently of the switching device.

In particular, the device according to the invention enables a particularly simple final assembly of the device and/or retrofitting of existing switching devices with the electronics module. The electronics module is preferably designed in such a way that, apart from the mechanical connection of the switching device and the electronics module, no separate wiring or the like has to be carried out on the switching device, insofar as the sensor device in particular reaches a position during the mechanical connection process in which it detects the desired measured variable be able.

The transfer component serves as a sort of adapter between the sensor component and the further processing component for the purpose of establishing an electrical and/or optical connection between the sensor component and the further processing component. The transfer component preferably only serves to forward the output signal of the sensor component to the further processing component. The output signal of the sensor component is therefore processed for the first time in the further processing component.

The sensor component, the transfer component and the further processing component preferably form separate components. In this respect, in such an embodiment, the further processing component can be handled, in particular assembled and exchanged, independently of the sensor component and the transfer component. The same applies accordingly to the sensor component and to the transfer component. This enables the respective component to be replaced separately, for example in the event of a defect.

However, it is also quite conceivable that the sensor component and the transfer component are realized in one and the same component, in particular that this component and the further processing component form separate components. In this respect, in such an embodiment, the further processing component can be handled, in particular assembled and exchanged, independently of the sensor component and the transfer component. The sensor component and the transfer component, on the other hand, can only be handled, in particular assembled and exchanged, together. The advantage of such an embodiment is, in particular, that the range of functions of the electronic module in Can be determined essentially by the further processing component used and identical parts can be used for the sensor and transfer component. In such an embodiment, it is conceivable, for example, for the sensor component and the transfer component to be mounted on one and the same circuit board, or for the printed circuit board to form the sensor component and the transfer component, with the common circuit board extending from the first housing section into the second housing section . The printed circuit board that forms the sensor component and the transfer component can certainly be designed as a printed circuit board.

It is considered particularly advantageous if the sensor component is mounted exclusively in the first housing section and/or the transfer component is mounted exclusively in the second housing section and/or the further processing component is mounted exclusively in the third housing section. However, it is also quite conceivable that areas of the transfer component are mounted in the first housing section, for example conductor tracks of a printed circuit board partially extend into the first housing section. It is also conceivable that areas of the sensor component are mounted in the second housing section, for example conductor tracks of a printed circuit board partially extend into the second housing section.

The switching device preferably has a receiving area on the rear side opposite the front side, with the first housing section of the electronic module being arranged in the receiving area. Due to the fact that the first housing section of the electronics module is arranged in the receiving area of the switching device, the device has a particularly small extent in the vertical direction. The vertical direction runs from the front side of the switching device in the direction of the rear side of the switching device.

The electronics module is equipped in particular with electronics for measuring and/or processing, for example to permanently monitor or measure all current and voltage-related data and/or into the To monitor switching device introduced electrical fuses and their condition or to monitor the switching state of the switching device.

It is considered to be particularly advantageous if the first housing section is arranged completely within the receiving area of the switching device in the vertical direction. As a result, the installation space requirement of the device in the vertical direction is not increased or at least hardly increased compared to the installation space requirement of the switching device as such.

In addition to requiring less installation space, the arrangement of the first housing section in the receiving area of the switching device has the advantage that the mechanical stability of the connection between the switching device and the electronic module is increased, since the housing of the switching device at least partially overlaps the first housing section of the electronic module in the vertical direction, as a result of which at least in additional stabilization is achieved in a transverse direction of the device.

The arrangement of the first housing section in the receiving area thus also increases the mechanical stability of the entire device in a simple manner. Accordingly, additional connecting means for the purpose of mechanically connecting switching device and electronic module can be dispensed with, or at least their number can be reduced, which simplifies connecting switching device and electronic module and/or detaching switching device and electronic module.

Because the second housing section and the third housing section protrude in the longitudinal direction relative to the switching device, the device has a particularly favorable design with regard to the installation space that is typically available. Thus, busbars on which the device is to be arranged are typically arranged in a switch cabinet, with a plurality of switching devices typically being arranged adjacent to one another in such a switch cabinet in the transverse direction of the switching devices. By protruding the first housing section and the second housing section in the longitudinal direction of the space requirement is thus Transversal facility not increased so use of electronic module does not negatively impact transversal space requirements. Accordingly, in the case of already existing arrangements of switching devices on busbars, it is possible to retrofit one or more of the switching devices with an electronics module without having to change the position of the other switching devices on the busbars. On the other hand, there is typically space available in the longitudinal direction of the switching devices, so that the switching devices can easily be provided with an electronic module.

It is considered advantageous if the second housing section adjoins the first housing section in the longitudinal direction of the switching device and the third housing section adjoins the second housing section in the direction of the front side, thus counter to the vertical direction. This design means that the space required in the longitudinal direction is particularly small and the device as such is particularly compact.

It is considered particularly advantageous if the third housing section can be removed from the second housing section from the front side, ie from a side facing the operator. In particular, the third housing section can be detached from the second housing section even when the switching device and electronic module are in the connected state.

The first housing section and the second housing section are preferably permanently connected to one another, in particular formed by the same component. The third housing section is preferably detachably connected to the second housing section. As a result, the further processing component can be exchanged and installed in a particularly simple manner.

It is considered to be particularly advantageous if the third housing section adjoins the housing of the switching device in the longitudinal direction of the switching device.

In particular, it is provided that the third housing section and the second housing section by means of separate connecting means, for example by means Screws, are detachably connected to one another, the connecting means being accessible from a side of the third housing section which is remote from the second housing section. As a result, the connecting means can be detached from a side facing the operator in the installed state, for example in order to remove the third housing section from the second housing section.

It is considered particularly advantageous if the further processing component is detachably mounted in the third housing section, in particular the further processing component can be pushed into the third housing section from the side of the third housing section facing the second housing section.

It is considered particularly advantageous if the further processing component is supported at the front on a partial area of the third housing section and at the rear on the second housing section or the transfer component. As a result, the further processing component is held in position particularly easily and securely in the vertical direction in the assembled state of the two housing sections and can be detached particularly easily from the third housing section when the third housing section is detached from the second housing section. This facilitates the installation of the further processing component and any replacement of the further processing component. In particular, additional connecting means and/or latching means for fixing the position of the further processing component in the third housing section for the purpose of fixing the position in the vertical direction can be dispensed with.

It is considered to be particularly advantageous if the transfer component has a first connection device and the further processing component has a second connection device, wherein the first connection device and the second connection device can be electrically and/or optically coupled to one another in order to establish an electrical and/or optical connection between the Handover component and the further processing component by electrically and / or optically coupling the first connection device to the second Connecting device for the mechanical connection of the second housing section and the transfer component arranged therein to the third housing section and the further processing component arranged therein. As a result, it is not necessary to separately establish an electrical and/or optical connection between the transfer component and the further processing component of the electronics, for example manual cabling, since the first connecting device is electrically and/or optically connected during the process of mechanically connecting the second housing section to the third housing section coupled to the second connection device. The term "coupling" means that a desired electrical and/or optical connection is established.

This configuration simplifies the assembly effort and in particular simplifies an exchange of the further processing component, in particular in the event that the further processing component has a defect or is to be exchanged for another further processing component.

It is considered particularly advantageous if the first connecting device and/or the second connecting device has a spring contact, in particular the spring contact of the second connecting device is formed on a side of the further processing component facing the second housing section. The use of a spring contact ensures particularly reliable electrical contact, even with manufacturing or assembly tolerances.

The first connection device and the second connection device are preferably coupled by contacting a contact surface of one connection device with the spring contact of the other connection device.

The input current conductors are preferably spaced apart from the rear of the switching device, insofar as they are set back inward relative to the rear of the switching device. This design of the switching device is in particular simple way formed the receiving area of the switching device, which is free of input current conductors.

The electronics module is preferably arranged in the receiving area in such a way that the electronics module is arranged between the input current conductors and the busbars.

In particular, it is provided that the housing of the switching device on the rear side of the switching device, i.e. in the vertical direction, protrudes from the first housing section and/or is flush with it, particularly preferably protrudes from the first housing section and the second housing section and/or is flush with them .

It is considered advantageous if the further processing component and/or the transfer component and/or the sensor component has a circuit board, in particular the further processing component and the transfer component and the sensor component each have a circuit board. However, it is also quite conceivable that the transfer component and the sensor component have a common printed circuit board.

The further processing component is preferably designed as a measuring circuit board. The sensor component is preferably designed as a signal circuit board or has at least one signal circuit board. The transfer component is preferably designed as a transfer board.

It is considered particularly advantageous if the sensor component has a printed circuit board, with all the components of the sensor component, for example a current sensor, in particular in the form of a Hall sensor, a voltage sensor or a voltage tap, being mechanically connected to the printed circuit board. As a result, the sensor component is particularly easy to handle and can therefore be installed and/or replaced as a unit.

Any voltage taps are preferably designed as pogo pins.

It is considered particularly advantageous if the transfer component has a printed circuit board, with all the components of the transfer component being mechanically connected to the printed circuit board. As a result, the transfer component is particularly easy to handle and can therefore be installed and/or replaced as a unit.

It is considered particularly advantageous if the further processing component has a printed circuit board, with all the components of the further processing component being mechanically connected to the printed circuit board. As a result, the further processing component is particularly easy to handle and can therefore be installed and/or replaced as a unit.

It is considered advantageous if the sensor component has a printed circuit board, with a component side of the printed circuit board facing away from the sensor component of the switching device and/or with the transfer component having a printed circuit board, with a component side of the printed circuit board facing the further processing component. This design makes it possible to arrange the printed circuit boards of the respective component in a particularly favorable manner. The printed circuit board of the sensor component and the printed circuit board of the transfer component are preferably arranged offset from one another in the vertical direction, with the printed circuit board of the sensor component being offset in the direction of the front side in relation to the printed circuit board of the transfer component and accordingly the printed circuit board of the transfer component offset in the direction of the rear in relation to the printed circuit board of the sensor component is arranged. Due to the fact that the transfer component and the sensor component each have a printed circuit board and are not implemented in the same printed circuit board or have a common printed circuit board, the printed circuit boards of the respective components can be arranged in a staggered manner. This makes it possible to position the printed circuit board of the sensor component as close as possible to the input current conductor, which has an advantageous effect on the detection of the desired measured variables and any voltage tap that is intended to contact the input current conductor. In contrast, the transfer component can be positioned as far away from the front side of the switching device or the front side of the device in order to have as large a space as possible for the Provide further processing component in high direction. By using two separate printed circuit boards, the conflicting requirements with regard to the arrangement of the transfer component and the sensor component can be implemented.

It is considered to be particularly advantageous if the further processing component has a printed circuit board, the printed circuit board having a main extension area, a normal vector of the main extension area running in the transverse direction or essentially in the transverse direction, which in the installed state typically runs in the longitudinal direction of the busbars, of the switching device. In the present case, “substantially in the transverse direction” is understood to mean an arrangement in which the normal vector runs at an angle of >0° to ≦10° to the transverse direction of the switching device. This design means that a particularly small amount of space is required in the transverse direction. This is particularly advantageous when the further processing component is designed such that it would protrude in the transverse direction of the switching device relative to the switching device in an arrangement in which the normal vector would run in the longitudinal direction of the switching device.

Such a design is also advantageous if one and the same further processing component is to be used in different switching devices, for example in switching devices with different extents in the transverse direction. So it is quite conceivable that the further processing component is used for a switching device with a larger transverse extent, for example a switching device for NH fuses of size 1 or larger, with the normal vector in the longitudinal direction of the switching device, but for a switching device with a smaller transverse extent, for example a switching device for NH fuses of size 00, with which the normal vector is used in the transverse direction.

In order to enable data exchange with other electronic components, in particular those arranged outside of the facility, it is considered to be particularly advantageous if the further processing component, in particular the Measurement board having a communication interface. The communication interface is preferably a hardware interface. The communication interface is, for example, a Modbus/RTU interface, a Modbus/TCP/IP interface, a CAN bus interface, an Ethernet interface or a Profinet interface. It is considered particularly advantageous if the interface is accessible from the front of the switching device.

It is entirely conceivable that the further processing component has a connection for an external power supply for the further processing component and/or the sensor component and/or the transfer component.

It is considered advantageous if the sensor component has at least one current transformer and/or at least one voltage transformer, preferably a number of current transformers and/or voltage transformers corresponding to the number of contact pairs, with the respective current transformer and/or voltage transformer being assigned to one of the input current conductors. The current transformer can be used, for example, to detect the current flowing through the switching device, for example to measure the power consumption of a consumer connected to the outlet of the switching device. The current transformer can be, for example, a current transformer with a core or a current transformer without a core, for example a Rogowski coil. The voltage tap serves in particular to monitor the voltage present at a current-carrying component of the switching device, for example the input current conductor. However, the voltage tap can also be used to supply power to other components of the electronic module, in particular to supply power to the further processing component. The sensor component can also include a current sensor, such as a Hall sensor. Furthermore, the sensor component can also have other sensors, such as temperature sensors or moisture sensors. Furthermore, the sensor component can also have a fuse monitor.

The respective current and/or voltage sensor and/or current and/or voltage converter and/or voltage tap is preferably mechanically connected to a printed circuit board of the sensor component, in particular the respective converter is soldered to the printed circuit board and/or plugged onto the printed circuit board.

The device is preferably connected to the busbars by means of a fastening means penetrating the input current conductor, in particular by means of a fastening screw.

It is considered particularly advantageous if the current transformer has a through-opening for receiving the fastening element connecting the input current conductor to the busbar, the first housing section having a bearing means for mounting the current transformer, the bearing means penetrating the through-opening of the current transformer. The entire sensor component can also be stored via the storage of the current transformer in the storage means, in particular if the current transformer is mechanically connected to a printed circuit board of the sensor component. In such a design, the fastening means can also serve as the primary conductor for the current transformer.

It is quite conceivable that a copper roller is additionally arranged in the area of the bearing means, with the fastening means penetrating the bearing means and the copper roller and the copper roller being arranged in the area of the through-opening of the current transformer. The copper roll serves in particular as a primary conductor for a current sensor. Preferably, the copper roller makes contact with the busbar and the input conductor when the device is mounted on the busbars.

The first housing section is preferably held in a locking manner in the switching device, in particular in a locking manner in the receiving area. In this context, it is considered to be particularly advantageous if the first housing section has one or more latching structures, preferably projecting in the direction of the front side, and the housing of the switching device Has locking structures corresponding, preferably internal, counter-structures.

The latching structures are preferably released from the counter-structures from the rear of the device.

It is considered advantageous if the electronics module can be connected to the switching device from the rear of the switching device, preferably the first housing section can be pushed into the receiving area counter to the vertical direction.

It is entirely conceivable that the third housing section and the housing of the switching device have cooperating guide means for guiding the movement of the third housing section relative to the housing of the switching device. This is advantageous, for example, when connecting the electronic module to or detaching the electronic module from the switching device and/or when connecting or detaching the third housing section from the second housing section.

Preferably, the third housing section can also be detached from the second housing section when the switching device and electronic module are in the connected state. The loosening preferably takes place in such a way that, after loosening any connecting means, the third housing section is pushed in the direction of the front side. However, it is also entirely conceivable that the third housing section is initially displaced in the direction of the front side in order to detach the third housing section from the second housing section, and then the third housing section is displaced in the longitudinal direction in order to detach the third housing section from the housing of the switching device.

It is considered advantageous if the transfer component and the sensor component are electrically and/or optically connected to one another via a preferably detachable cable. For this purpose it is quite conceivable that the sensor component and / or the transfer component has a plug or a have socket. This simplifies assembly and replacement of components.

It is considered advantageous if the housing of the electronics module has a cover on the back that is detachably connected to the rest of the housing of the electronics module. This allows particularly easy access to the sensor component and/or the transfer component from the rear of the device or the electronics module. As a result, access to the sensor component and/or the further processing component is possible in a simple manner even when the switching device and electronic module are connected to one another.

The cover is preferably designed in several parts, in particular in two parts. On the one hand, this facilitates the production of the cover and, on the other hand, the assembly and disassembly of the cover. The rear cover of the electronic module, in particular the cover parts, is preferably connected by means of one or more connecting screws.

The housing of the electronics module preferably completely encloses the sensor component, the transfer component and the further processing component.

The first housing section preferably has a smaller width extension than the second housing section. In particular, the width of the second housing section corresponds to the width of the switching device.

It is considered to be particularly advantageous if the input current conductors are at a distance that is suitable for mounting on busbars with a distance of 100 mm.

It is considered particularly advantageous if the first housing section has a front wall facing the input current conductors. It is quite conceivable that the front wall has through-openings for the fastening means has and/or voltage taps of the sensor component pass through the front wall.

The third housing section preferably has a cable routing channel. It is quite conceivable that this cable routing channel is implemented in a separate component that is detachably connected to the third housing section. This separate component can preferably be slid onto the third housing section from the front side.

The invention is illustrated in more detail in the following figures using an exemplary embodiment, without being restricted to this exemplary embodiment.

the Figures 1 to 13 show an embodiment of the device according to the invention for arrangement on busbars 24. Such an arrangement is in 13 shown.

The switching device 1 has a front side 3 facing away from the busbars 24 and a rear side 12 facing towards the busbars 24 . Furthermore, the switching device 1 has an actuating lever 35 on the front for switching the switching device 1 .

The device as such also has a front side facing away from the busbars 24 and a rear side facing towards the busbars 24, the front side of the device essentially being formed by the front side 3 of the switching device 1 and the rear side of the device essentially being formed by a rear side of the electronic module 2 is formed.

The switching device 1 has a housing 4 and contact pairs arranged in a longitudinal direction X of the switching device 1 for receiving fuses on the front. The contact pairs are not shown in detail in the figures. The contact pairs are located in the area of the fuse holders 18, which are also formed in the longitudinal direction X of the switching device 1. One contact of the contact pair is connected to an input current conductor 15 and the other contact of the contact pair is connected to an outgoing current conductor 25. The outgoing current conductor 25 opens into a connection space 19 of the switching device 1.

The electronics module 2 has a housing 5 , 6 , 7 , 8 , the housing 5 , 6 , 7 , 8 having a first housing section 5 , a second housing section 6 , a third housing section 7 and two cover parts 8 .

The sensor component 9, the transfer component 11 and the further processing component 10 are each designed as a separate component so that the respective component 9, 10, 11 can be handled independently of the other components 9, 10, 11. In the present case, the sensor component 9 is mounted exclusively in the first housing section 5, the transfer component 11 is mounted exclusively in the second housing section 6 and the further processing component 10 is mounted in the third housing section 7 and partially protrudes into the second housing section 6.

Like that one in particular figure 5 As can be seen, the switching device 1 has a receiving area 13 on the rear side 12 opposite the front side 3, with the first housing section 5 of the electronics module 2 being arranged together with the sensor component 9 in the receiving area 13, in the present case the receiving area 13 completely covers the first housing section 5 picks up.

The second housing section 6 and the third housing section 7 of the electronics module 2 , on the other hand, protrude in the longitudinal direction X of the switching device 1 on an end face of the switching device 1 opposite the connection space 19 with respect to the switching device 1 .

In the present case, the electronic module 2 is connected to the switching device 1 from the rear 12 of the switching device 1, with the electronic module 2 being displaced in the direction of the arrow 26, thus in the direction of the front side 3 of the switching device 1, with respect to the switching device 1 for this purpose.

In the connected state, the first housing section 5 is held in a latching manner in the receiving area 13, with the electronics module 2 having latching structures 27 protruding in the direction of the switching device 1 for this purpose in the region of the first housing section 5, which in the connected state with the region of the housing 4 of the Switching device 1 trained counter-structures cooperate.

Like that one in particular figure 5 it can be seen that the three input current conductors 15 are set back in relation to the rear side 12 of the switching device 1 , as a result of which side walls of the housing 4 on the rear side 12 protrude in relation to the input current conductors 15 . As a result, the receiving area 13 is formed, which in the present case is essentially cuboid. When the switching device 1 and the electronic module 2 are connected to one another, the side walls of the housing 4 of the switching device 1 on the rear side 12 of the switching device 1 are flush with the first housing section 5 and the second housing section 6 of the electronic module 2 .

In the present case, the first housing section 5 and the second housing section 6 are formed by the same component which, for example, is shown in FIG 9 is shown, and the third housing section 7 is releasably connected to the second housing section 6 . In the present case, the third housing section 7 is connected to the second housing section 6 by means of two screws, the two screws being accessible from the front side 3 . The connecting screws pass through the third housing section 7 and each engage in a screw boss 28 formed in the area of the second housing section 6 .

Like that one in particular 1 As can be seen, the second housing section 6 adjoins the first housing section 5 in the longitudinal direction X of the switching device 1 and the third housing section 7 adjoins the second housing section 6 in the direction of the front side 3, thus counter to the Z-direction.

Like the one in particular 2 , 8 and 9 As can be seen, the first housing section 5 has a smaller width extension, i.e. an extension in the Y-direction, than the second housing section 6 and third housing section 7.

In the present case, the further processing component 10 is designed as a measurement circuit board. The further processing component 10 is removably stored in the third housing section 7, the further processing component 10 presently facing from a side of the second housing section 6 third housing section 7 can be pushed into the third housing section 7 or pushed out of the third housing section 7 .

The third housing section 7 has a stop for the further processing component 10, this stop preventing further insertion of the further processing component 10.

The further processing component 10 embodied as a measuring board has a printed circuit board, the printed circuit board having a main extension area, with a normal vector 29 of the main extension area running in the transverse direction Y of the switching device 1 .

The further processing component 10 has a plurality of communication interfaces 23 accessible from the front side 3 of the switching device 1, the third housing section 7 having front openings for this purpose.

The transfer component 11 and the sensor component 9 each have a circuit board, with an assembly side 16 of the circuit board facing away from the sensor component 9 of the switching device 1 and an assembly side of the circuit board facing the transfer component 11 of the further processing component 10 .

In the present case, the printed circuit boards of the sensor component 9, the transfer component 11 and the further processing component 10 are each a single-sided printed circuit board.

Like the one in particular 6 and 10 can be seen, all components of the sensor component 9, in particular the current transformer 17 and the voltage taps 22, which are used to contact the input current conductor 15, are mechanically connected to the printed circuit board of the sensor component 9 and can therefore be handled as a unit.

In the present case, the sensor component 9 and the transfer component 11 are electrically connected to one another via a flexible cable 30 .

Like the one in particular 6 , 8th and 10 it can be seen that the two printed circuit boards of the sensor component 9 and the transfer component 11 are offset from one another in the vertical direction Z. In the present case, the printed circuit board of the sensor component 9 is arranged closer to the front side 3 of the switching device 1 than the printed circuit board of the transfer component 11.

The transfer component 11 has a first connection device, not shown in detail in the figures, this connection device being formed by contacting surfaces of the printed circuit board in the present case, and the further processing component 10 has a second connection device 14, this connection device 14 being formed in the present case by a plurality of spring contacts. The first connecting device and the second connecting device 14 can be electrically coupled to one another in order to establish an electrical connection between the transfer component 11 and the further processing component 10 by electrically coupling the first connecting device to the second connecting device 14 when mechanically connecting the second housing section 6 and the transfer component 11 arranged therein with the third housing section 7 and the further processing component 10 arranged therein. In the present case, the connecting device 14 is formed on a side of the further processing component 10 which faces the second housing section 6 .

To mount the current transformer 17 in the first housing section 5 and thus to mount the sensor component 9 in the first housing section 5, the first housing section 5 has three bearing means 21, with these bearing means 21 being essentially circular-cylindrical and each having a through-opening 20 in the respective current transformer 17 and enforce the circuit board. A copper roller 36 is arranged on the respective bearing means 21 in such a way that the bearing means 21 passes through the copper roller 36 . When the device is connected to the busbars 24 , connection screws (not shown) pass through the respective input current conductor 15 , the respective current transformer 17 , the respective copper roller 36 and the respective bearing means 21 and are screwed to the respective busbar 24, which is assigned to the input current conductor 15.

In order to cover the rear of the sensor component 9 and the transfer component 11, the housing 5, 6, 7, 8 of the electronics module 2 has two cover parts 8 which are detachably connected to the rest of the housing 5, 6, 7 on the rear. The cover parts 8 are connected to the rest of the housing, specifically the first housing section 5 and the second housing section 6, by means of separate connecting means designed as screws. It is quite conceivable that the screws also serve to fix the position of the printed circuit board of the sensor component 9 or the printed circuit board of the transfer component 11 .

The third housing section 7 can also be detached from the rest of the device when the switching device 1 and electronic module 2 are in the connected state, as is shown in FIG 12 is shown. The loosening takes place in such a way that, after loosening the connecting means, the third housing section 7 only has to be moved in the direction of the arrow 32, thus counter to the vertical direction Z. A connection takes place correspondingly in the opposite direction.

In an alternative embodiment shown in the Figures 14 to 16 is shown, the third housing section 7 must first be moved in the direction of arrow 33, i.e. in the direction of the front side 3, in order to release the third housing section 7 and then the third housing section 7 must be moved in the direction of arrow 34, i.e. in the longitudinal direction X. A connection takes place correspondingly in the opposite direction.
