Description
Technical Field
The utility model relates to a data exchange device for a low-voltage protective switching device, having an insulating material housing in which an electronic printed board assembly is accommodated and held. The utility model also relates to an installation method for such a data exchange device, and to a data exchange device comprising a data exchange device and at least one serial installation device (german:
) The device is formed.
Background
Electromechanical protective switching devices, such as power switches, power protection switches, fault current protection switches and arc or fire protection switches, are used for monitoring and protecting electrical circuits and are used in particular as switches and safety elements in electrical energy supply and distribution networks. For monitoring and protecting the circuit, the protective switching device is connected in an electrically conductive manner to the line of the circuit to be monitored via two or more connection terminals in order to interrupt the current flow in the respective line to be monitored, if necessary. For this purpose, the protective switching device has at least one switching contact which can be opened when a predefined state occurs, for example when a short circuit or a fault current is detected, in order to separate the circuit to be monitored from the network of lines. Such protective switching devices are also known in the field of low-voltage technology as series-mounted devices.
Since the available installation space in electrical installation technology, for example in electrical distribution panels, is often very strongly limited, there is a need for a switching protection device which is as compact as possible. On the other hand, more and more functionality is being integrated into a device, or a combined device is being developed that covers the functional scope of a plurality of individual devices: for example, so-called FI/LS protection switching devices exist, which combine the functional range of a conventional fault current protection switch (FI) and the functional range of a line protection switch (LS). Furthermore, higher and higher rated current intensities should be achieved. These developments have led to the fact that, within the device, less and less structural space is available.
During increasing digitalization, there is also a requirement on the part of some users that the status of the switchgear installed in the electrical installation be detected and can be transmitted to a central control center.
SUMMERY OF THE UTILITY MODEL
The object of the utility model is therefore to provide a data exchange device for a plurality of serially connected installation devices and an installation method for such a data exchange device, which provides the above-described functionality with regard to the detection and transmission of the required data and information and which is characterized by a compact design and low production costs.
According to the utility model, this object is achieved by a data switching device according to the utility model and an installation method for such a data switching device. Advantageous embodiments of the data switching device according to the utility model are described below.
The data exchange device for a low-voltage protective switching device according to the utility model has an insulating material housing which itself has a front side, a fastening side opposite the front side, and narrow and wide sides connecting the front side and the fastening side, and comprises at least one housing shell and a cover part. The housing shell and the covering element can be fixed to one another in a first direction by means of suitable connecting means, so that a circumferential splicing line is formed. Furthermore, the data exchange device has an electronic printed board assembly which is accommodated and held in an insulating material housing. The insulating material housing has first centering means on its inner side for positioning the printed board assembly in a first direction. The printed board assembly is fixed in a form-fitting manner in the insulating material housing without its own fixing means by fixing the covering part to the housing shell by means of the first connecting means.
The term "printed circuit board assembly" is understood to mean a printed circuit board (english language PCB) on which a plurality of electronic components required for data exchange are arranged. By fixing the covering part on the housing shell, the printed board assembly is held in a form-fitting manner in the first direction by means of a first centering means which is constructed on the inner side of the insulating material housing. In this way, separate fastening means, for example screws, can be dispensed with for fastening the printed board assembly in the housing shell. The printed board assembly is fixed only by the first connecting device, and the cover member is fixed on the housing case with the first connecting device. This significantly simplifies the installation effort.
In an advantageous embodiment of the data exchange device, the inner side of the insulating material housing has second centering means for positioning the printed board assembly in the second direction and third centering means for positioning the printed board assembly in the third direction.
In order to accurately position the printed board assembly in all three orientation directions, the insulating material housing has second and third centering means for positioning the printed board assembly in the second and third directions. In this way, a positionally accurate positioning of the printed board assembly in the insulating material housing can be achieved with at the same time little installation and production effort.
In a further advantageous embodiment of the data exchange device, the first centering means is formed in the cover part and the second and third centering means are formed in the housing shell.
This results in the advantage that the printed board assembly is first positioned in the second and third directions when it is inserted into the housing shell before the printed board assembly is positioned and fixed in the third direction by closing the housing, i.e. by attaching the cover part to the housing shell. This further simplifies the assembly effort.
In a further advantageous embodiment of the data exchange device, the centering means is connected integrally to the respective housing part. By the integral design of the first centering element on the cover part or of the second and third centering elements on the housing shell, the manufacturing effort required for producing the housing shell and the cover part can be reduced.
In a further advantageous embodiment of the data exchange device, the connecting means for fastening the covering part to the housing shell is designed as a latching means. The covering element can be mounted on the housing shell without tools by means of a latching connection, for example a bayonet connection, as a result of which the mounting effort and thus the production costs can be further reduced.
In a further advantageous embodiment of the data exchange device, the insulating material housing has a width of one division unit (german).
Especially, the width of only one division unit (1TE, corresponding to 3/4 inches, about 18 mm) shows great advantages, based on the structural space which is only limitedly available in the wiring distribution board.
In a further advantageous embodiment, the data exchange device is designed as a serial-mounted device and can be mounted on the mounting rail.
In the low-voltage distribution panels used today, the protective switchgear to be arranged, for example a line protection switch, a residual-current circuit breaker or a fire protection switch, is fixed by means of a so-called support rail, on which the switchgear is suspended and fixed. Since the switching devices are installed here in series side by side, they are also referred to as series-installed devices. In order to be able to fix the data exchange device in such a wiring panel without great additional installation effort, it is advantageously likewise designed as a serial installation device.
In a further advantageous embodiment, the data switching device has a data storage device for storing data of one or more series-mounted devices that can be connected wirelessly to the data switching device.
The data exchange device may be wirelessly connected with one or more series-mounted devices in order to detect and store data, e.g. status information and/or measurement data, of the series-mounted devices. Since the devices are installed in series, for example by means of a bluetooth or ZigBee wireless connection, commissioning or use can be significantly simplified.
The device or arrangement according to the utility model has a data exchange device of the aforementioned type and at least one series-mounted device, which is communicably connected to the data exchange device.
The expression "communicably connected" is understood to mean that a preferably wirelessly designed communication connection exists between the data exchange device and the series-mounted device, by means of which communication connection, for example, status information of the series-mounted device can be transmitted to the data exchange device. Already existing standards, such as ZigBee or bluetooth, are advantageously used for this purpose. It is particularly advantageous if a plurality of series-mounted devices, preferably all series-mounted devices arranged in the electrical wiring panel, have such a communication connection to the data exchange device that status information of a plurality of or preferably all series-mounted devices can be transmitted to the data exchange device. In this way, the status of the electrical installation can be monitored remotely in almost real time.
The installation method according to the utility model for a data exchange device of the aforementioned type has the following steps:
a) positioning the printed board assembly in the second direction and the third direction by placing the printed board assembly into the housing shell,
b) the printed board assembly is positively fixed in the insulating material housing by fixing the cover part on the housing shell by means of a connecting element acting in the first direction.
By means of the mounting method according to the utility model, the printed board assembly can be positioned precisely in the insulating material housing without great effort, whereby a quick and simple mounting of the data exchange device can be achieved.

Detailed Description
Fig. 1 to 3 show a data exchange device 1 according to the utility model in different views. The data exchange device 1 is used for communication with one or more low-voltage protective switching devices and has an insulating material housing 2, which itself has a front side 3, a fastening side 4 opposite the front side 3, and narrow sides 5 and wide sides 6 connecting the front side 3 and the fastening side 4. The data exchange device 1 is designed as a series-mounted device with a housing width of only one division unit TE and can be fastened to a support rail or a carrier rail (not shown) by means of a fastening means 10 designed on the fastening side 4, which fastening means serves, for example, as a standard in electrical distribution panels for fastening the series-mounted device.
Structurally, the insulating material housing 2 is designed in a shell construction and has a housing shell 7 and a covering element 8. The housing shell 7 and the covering element 8 are fixed to one another by means of a plurality of connecting elements 9 which act in the first direction R1, forming a circumferential stitching line 11. The second direction R2 is defined by the surface normal of the narrow side 5 and the third direction R3 is defined by the surface normal of the front side 3. The data exchange device 1 is connected to an external device, for example a laptop or tablet computer, via a cable via an ethernet socket 12 arranged on the narrow side 5. A connection contact 13 for the external current supply of the data switching device 1 is arranged on the narrow side 5 opposite the ethernet socket 12.
Fig. 4 schematically shows an exploded view of the data exchange device 1 in a perspective view. A printed board assembly 14 is arranged in the insulating material housing 2 formed by the housing shell 7 and the cover member 8, and a plurality of electronic components 15 necessary for data exchange are arranged on the printed board assembly. For this purpose, for example, the group of structures and the interface for wireless communication with one or more low-voltage protection switching devices are included, but also an ethernet socket 12 for wired communication with external devices, the wireless communication being effected, for example, by bluetooth or ZigBee. Connection contacts 13 for external current supply to the data exchange device 1 are also arranged on the printed board assembly 14.
Fig. 5 and 6 each show a schematic illustration of an open insulating material housing 2 in a side view. Fig. 5 shows an internal view of the housing shell 7 and the printed board assembly 14 inserted therein, while fig. 6 shows the empty, not equipped interior of the housing shell 7. First centering devices 16 configured on multiple locations of housing shell 7 are used to precisely position printed board assembly 14 in first direction R1. The present invention relates to a housing contour formed on the housing shell 7, which is formed on the inside of the housing shell 7 and serves as a support point for a printed board assembly 14 to be inserted. The cover member 8 may also have a corresponding housing profile serving as a first centering means, by the height of which in the first direction R1 the supporting gap of the printed board assembly 14 in the first direction R1 may be defined. If the cover part 8 is fixed to the housing shell 7 by means of the connecting means 9, the printed board assembly 14 is thereby also accurately positioned in the first direction R1. For this purpose, no additional fastening, for example by means of screws or rivets, is required.
Furthermore, the housing shell 7 has second centering means 17 and third centering means 18, which enable a precise positioning of the printed board assembly 14 along the second direction R2 and the third direction R3. Here, it is also a housing contour formed on housing shell 7, which is formed on the inside of housing shell 7, and the support gap of printed board assembly 14 in second or third direction R2 or R3 can be set by the dimension of the housing contour in second and/or third direction R1 or R3. By means of the centering means 16, 17, 18, a stable and precise positioning of the printed board assembly 14 in the insulating material housing 2 can be achieved without using additional fixing or mounting members. In addition to the installation and cost advantages already described, a very compact data exchange device 1 can be realized in this way.
The installation method according to the utility model for a data exchange device 1 of the aforementioned type is subsequently briefly explained with reference to fig. 7:
in a first method step 101, the printed board assembly 14 is inserted into the housing shell 7 and is positioned precisely in both directions by the second and third centering devices 17, 18 acting in the second direction R2 and the third direction R3.
Subsequently, in a second method step 102, the cover part 8 is fixed on the housing shell 7 by means of the connecting element 9 acting in the first direction R1, whereby the printed board assembly 14 is positively fixed in the insulating material housing 2 by means of the first centering element 16.
Since the printed board assembly 14 is the only component to be mounted in the insulating material housing 2, in addition to the fastening means 10 for fastening the data exchange device 1 to the support rail, the mounting effort can be significantly reduced. This is particularly suitable since the selected connecting means 9 are configured as a snap-on or detent connection, whereby the connection between the housing shell 7 and the covering element 8 can be established without the use of additional tools.
With the aid of the data switching device 1, data, for example status information and/or measurement data, can be collected from various protective switching devices which are coupled to the data switching device 1 for the purpose of providing information and, if necessary, processed further or forwarded. For this purpose, the data exchange device 1 has different communication interfaces, for example bluetooth, ZigBee or ethernet, wherein these interfaces are designed to be bidirectional, so that bidirectional communication is possible.
