Description

Technical Field

[0001] The utility model relates to a multi-module power cabinet structure, in particular to a power cabinet which can facilitate rapid assembly, disassembly and exchange of multiple modules. Background Art

[0002] Power cabinets play an increasingly important role in today's power systems. Power cabinets are usually used to store and distribute electrical energy in power systems. Usually, in order to achieve certain functions, some power cabinets often need to be equipped with modules with certain specific functions. Each module cooperates with each electrical component in the cabinet to output a specific voltage and current. When the number of modules in the power cabinet is small, the modules can be installed on the cabinet through the mounting plate or other mounting parts on the cabinet. However, when the number of modules increases, it is often not feasible to install all modules on the cabinet by the above method. The reasons are: 1. Each module requires a specific mounting part. As the number of modules increases, the number of mounting parts also increases, which eventually leads to the overall weight not meeting the relevant technical requirements; 2. When the number of modules increases, if the above traditional installation method is adopted, under a certain volume and size, there may not be enough space inside the cabinet to accommodate all modules. In addition, in order to set the address of each module, it is often necessary to change the DIP switch inside the module or change the program. When there are a large number of modules of a certain model, how to set the "address" of each module will become cumbersome and complicated. Therefore, when the number of modules is large, it is necessary to design a new structure to facilitate the identification, disassembly and interchange of multiple modules. Summary of the invention

[0003] The utility model aims to design a new modular power cabinet structure within the limited volume, weight and external dimensions of the power cabinet, so that the power cabinet can facilitate rapid identification, disassembly and interchange of multiple modules.

[0004] To achieve the above-mentioned purpose, the technical solution of the utility model is: a multi-module power supply cabinet, including a cabinet body, modules and two module plug-in boxes, the two module plug-in boxes are inserted into the cabinet body from the front of the cabinet body, and are fixed to the cabinet body column by corresponding screws passing through the side waist holes of the module plug-in box and the half waist holes of the front panel of the module plug-in box; the module is inserted into the module plug-in box along the module slide groove in the module plug-in box, and the module is fixed to the module plug-in box by screws passing through the half waist holes on the front panel of the module; the aviation plug on the module is matched with the aviation socket on the module plug-in box for fastening connection.

[0005] Furthermore, a plurality of columns are arranged inside the cabinet body, and the columns are welded to corresponding positions on the side of the cabinet body; and square holes and round holes in a linear array are opened on the columns.

[0006] Furthermore, the module plug-in box includes a plug-in box shell, a module slide slot, and an aerial plug-in mounting plate. The left and right sides of the module plug-in box shell are provided with waist holes, which correspond to the holes of the cabinet columns; the front panel of the module plug-in box is provided with two upper and lower rows of threaded holes, the bottom of the module plug-in box is provided with a certain number of countersunk holes, and the back of the module plug-in box is provided with a number of threaded holes; the front panel of the module plug-in box is welded with two mirror-image connecting flanges, each connecting flange is provided with two half waist holes, and the two half waist holes correspond to the holes of the cabinet columns.

[0007] Furthermore, the number and positions of the threaded holes on the module slideway correspond to the countersunk holes at the bottom of the module plug-in box, and the module slideway is installed on the module plug-in box by countersunk screws.

[0008] Furthermore, the module slide is fixed to the module plug-in box by means of countersunk screws passing through several countersunk holes at the bottom of the module plug-in box, and the aviation plug mounting plate is fixed to the back of the module plug-in box by means of screws passing through several half-waist holes on the aviation plug mounting plate; the aviation socket is fixed to the aviation plug mounting plate by means of screws passing through the threaded holes on the aviation plug mounting plate.

[0010] Furthermore, the module comprises an aviation plug, a guide rail and a module housing. The guide rails are mounted by countersunk screws on both sides of the module housing, and a plurality of half-waist holes are opened on the front panel of the module.

[0011] Furthermore, the aviation plug is installed on the back of the module and corresponds to the aviation socket, and the high level and ground signals on the module are extended to the corresponding address pins of the aviation plug through the leads.

[0012] Furthermore, the high level on the address pin of the aviation socket is short-circuited with the ground signal in different combinations, thereby achieving different high and low level address signal allocations.

[0013] The beneficial effects of the utility model are:

[0014] The power cabinet structure designed by the utility model can facilitate the rapid assembly and disassembly of multiple modules, can accommodate multiple modules in a limited volume, and also reduce the overall weight of the power cabinet to a certain extent, overcoming the shortcomings of traditional power cabinets that are limited by structural size, spatial position, and weight requirements.

[0026] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0027] like Figures 1 to 8 As shown, the utility model provides a multi-modular power cabinet structure, which mainly includes a cabinet body 1, a module 2 and two module plug boxes 3. The two module plug boxes 3 are inserted into the cabinet body 1 from the front of the cabinet body 1, and the corresponding screws are passed through the 9 waist holes on the side of the module plug box 3 and the 4 half waist holes on the front panel of the module plug box 3 (such as Figure 3 The module slots 6 in the module plug box 3 are fixed to the cabinet body column 4 by countersunk screws passing through the 8 countersunk holes at the bottom of the module plug box 3 (as shown in FIG. Figure 3As shown) is fixed to the module plug box 3, and the aviation plug mounting plate 7 is screwed through the four half waist holes on the aviation plug mounting plate 7 (as shown) Figure 4 The aviation socket 9 is fixed to the back of the module plug box 3 by screwing through the threaded hole on the aviation plug mounting plate 7. The module 2 can be pushed into the plug box along the groove in the module slide. In order to assemble and tighten the aviation plug 10 and the aviation socket 9, it is also necessary to fix the module 2 to the module plug box 3 by screwing through the half-waist hole on the front panel of the module 2.

[0028] like Figure 2 As shown, there are four columns 4 inside the cabinet body 1, which are welded to the corresponding positions on the side of the cabinet body. The columns 4 are provided with linear arrays of square holes and round holes 8, and the main function of the columns 4 is to strengthen the side strength of the cabinet and install other components such as plug-in boxes.

[0029] like Figure 3 , Figure 4 As shown in (a), (b), and (c), the module plug-in box 3 includes a plug-in box shell 5, a module slide 6, and an air plug mounting plate 7. The plug-in box shell 5 is processed by a combination of sheet metal bending and welding. The module slide 6 has a high precision requirement and is generally completed by machining. The left and right sides of the module plug-in box shell 5 are provided with waist holes 15, and the waist holes 15 correspond to the holes of the cabinet columns. The front panel of the module plug-in box 3 is provided with two rows of threaded holes in the upper and lower rows, a certain number of countersunk holes 16 are provided at the bottom of the module plug-in box 3, and four back threaded holes 14 are provided on the back of the module plug-in box 3; two mirror-image connecting flanges are welded on the front panel of the module plug-in box 3, and each connecting flange has two half waist holes 17. Similarly, the two half waist holes correspond to the holes of the cabinet columns. Therefore, the two module plug-ins 3 are installed on the cabinet columns 4 through the left and right openings of the modules and the openings of the front panel.

[0030] like Figure 5 , Figure 6 As shown in (a), (b), and (c), a certain number of threaded holes 18 are opened in the middle of the aviation plug installation plate 7, and the threaded holes 18 are used to install the aviation sockets 9 corresponding to the module aviation plug. The aviation plug installation plate 7 has half-waist holes 17 on both sides, and the half-waist holes 17 correspond to the back threaded holes 14 of the module plug box 3.

[0031] like Figure 7 As shown, the module 2 is mainly composed of an aviation plug 10, a guide rail 11 and a module housing 12. The guide rail 11 is installed at the bottom of the module 2 by countersunk screws, the aviation plug is installed at the back of the module 2, and two half-waist holes are opened on the front panel of the module 2. A handle 13 is provided on the module 2.

[0032] like Figure 8As shown, the number and position of the threaded holes 19 on the module slide 6 correspond to the countersunk holes at the bottom of the module plug-in box 3. The module slide 6 can be installed on the module plug-in box 3 by countersunk screws, and the length of the countersunk screws should not be too long to avoid interference with the module guide rail.

[0033] The aviation socket 9 corresponds to the aviation plug on the module 2 and is of the same model. The high level and ground signal on the module 2 are extended to the corresponding address pins of the aviation plug 9 through the lead wire, and the address pins on the aviation socket 9 also correspond to the corresponding signals. The high level on the address pin of the aviation socket is short-circuited with the ground signal in different combinations, thereby realizing different high and low level address signal allocations. If the high and low levels are specified in binary, each address pin connected to the address ground corresponds to a low level 0, otherwise it is a high level 1. The binary number of each address pin is converted into a decimal number and then summed to obtain the address of the aviation plug, and the address of the module connected to the aviation plug is determined accordingly.

[0034] If the order of the aviation socket addresses is specified in advance, each aviation socket address pin and the ground signal need to be short-circuited in different ways through leads. When the aviation sockets arranged in a certain order are installed, and other structural parts except the module have been installed on the cabinet, the module can be installed next.

[0035] Since the module plug box 3 has been installed with a slide groove, and the matching guide rail 11 is also installed at the bottom of the module 2, in the actual process of installing the module, it is only necessary to push the module 2 into the plug box along the groove in the module slide groove. In order for the aviation plug 10 to be assembled and fastened with the aviation socket 9, it is also necessary to fix the module to the module plug box by screws through the half-waist hole on the front panel of the module, and the assembly method of other modules is the same. When disassembling the module, it is only necessary to remove the two fixing screws on the front panel of the module, and then hold the handle on the module to pull the module out along the guide rail stroke. In this way, when the number of modules is large, all modules can be assembled and disassembled simply and quickly through the cooperation of the slide groove and the guide rail, and the cooperation of the aviation plug and the aviation socket. If a certain number of modules of the same type are installed in the plug box, it is not necessary to distinguish these modules separately and set addresses separately. The modules are interchangeable and the modules can be assembled to each aviation socket at will. In addition, if a module is damaged, it is not necessary to set the module address additionally when replacing a new module, and the module can be directly assembled inside.
