[0037] As described above, conventional power distribution cabinets generally support busbars through single flanges or clamp structures, but single flanges and clamp structures can only support rectangular busbars and are not applicable to special-shaped busbars. The embodiment of the present disclosure provides a power distribution cabinet 100 that can be applied to rectangular busbars and special-shaped busbars. Figures 1 to 8 The principles of the present disclosure are described.

[0038] Figure 1 A schematic structural diagram of a power distribution cabinet 100 according to some embodiments of the present disclosure is shown. Figure 2 Shows Figure 1 FIG. 1 is an enlarged schematic diagram of part A of the power distribution cabinet 100. Figure 1 to Figure 2 As shown, the power distribution cabinet 100 described herein may generally include a frame 4 , a base plate 5 , a back plate 6 , a pair of support members 1 , and a busbar.

[0039] Continue reading Figure 1 to Figure 2 In some embodiments, the bottom plate 5 may include multiple layers, and the multiple layers of bottom plates 5 are respectively arranged in parallel on the frame 4 . The back plate 6 is arranged on the frame 4 , and the back plate 6 may be arranged vertically between the multiple bottom plates 5 .

[0040] Figure 3 FIG. 2 shows a schematic diagram of the structure of a connecting member 2 and a pair of supporting members 1 according to some embodiments of the present disclosure. Figures 2 to 3 As shown, in some embodiments, the busbar is clamped between the paired support members 1. According to the difference in shape, the busbar may include a rectangular busbar and a special-shaped busbar 3. One of the paired support members 1 may be disposed on the bottom plate 5. Since the connecting member 2 is disposed between the paired support members 1 for fixing the paired support members 1, the paired support members 1 can be limited on the corresponding bottom plate 5.

[0041] The power supply mode of the power system generally includes a three-phase three-wire system and a three-phase four-wire system. In some embodiments, when the power supply mode of the power system includes a three-phase three-wire system, the number of busbars may include 3. In other embodiments, when the power supply mode of the power system includes a three-phase four-wire system, the number of busbars may include 4, which is not limited here. In the following, the power distribution cabinet of the present invention will be described based on the case where the power supply mode of the power system includes a three-phase four-wire system, and the case where the busbar includes a special-shaped busbar 3. The case where the power supply mode of the power system includes a three-phase three-wire system, and the case where the busbar includes a rectangular busbar are similar, and will not be repeated here.

[0042] Figure 4 A schematic diagram of the matching of a pair of support members 1, a connector 2, a special-shaped row 3, a back plate 6, a plug 7 and a grille 8 according to some embodiments of the present disclosure is shown. Figure 5 FIG. 1 is a schematic diagram showing the structure of a support member 1 according to some embodiments of the present disclosure. Figures 2 to 5 As shown, in some embodiments, the first limiting groove 11 and the second limiting groove 12 are respectively provided on the surfaces facing each other of the paired support members 1. That is, the first limiting groove 11 and the second limiting groove 12 are respectively provided on each support member 1. The first limiting grooves 11 on the paired support members 1 are arranged opposite to each other, and the second limiting grooves 12 on the paired support members 1 are arranged opposite to each other. The first limiting groove 11 may include a rectangular groove. The second limiting groove 12 may include at least one inclined surface 121 or at least one curved surface for matching with the special-shaped row 3.

[0043] Obviously, since the number of the busbars is 4, the number of the first limiting grooves 11 is also 4; similarly, the number of the second limiting grooves 12 is also 4.

[0044] With the above configuration, when the busbar includes a rectangular busbar, the two ends of the rectangular busbar can be located in the first limiting groove 11, and the rectangular busbar and the paired support members 1 can be limited by the connector 2 to install the rectangular busbar. When the busbar includes a special-shaped busbar 3, the two ends of the special-shaped busbar 3 can be located at least in the second limiting groove 12, and the special-shaped busbar 3 and the paired support members 1 can be limited by the connector 2 to install the special-shaped busbar 3. Therefore, according to the power distribution cabinet 100 of the embodiment of the present disclosure, it is possible to simultaneously meet the installation requirements of the special-shaped busbar 3 and the rectangular busbar. In addition, the specifications of the busbar are different according to different current levels. Therefore, according to the power distribution cabinet 100 of the embodiment of the present disclosure, it is possible to simultaneously meet the installation requirements of the special-shaped busbar 3 and the rectangular busbar of different specifications.

[0045] In some embodiments, when the busbar includes a special-shaped bar 3, the two ends of the special-shaped bar 3 can be set in the first limiting groove 11 and the second limiting groove 12 of the corresponding support member 1. In other embodiments, when the busbar includes a special-shaped bar 3, the two ends of the special-shaped bar 3 can only be set in the second limiting groove 12 of the corresponding support member 1. Figures 4 to 5 In some other embodiments, when the busbar includes a special-shaped bar 3, one end of the special-shaped bar 3 can be set in the first limiting groove 11 and the second limiting groove 12 of one of the support members 1, and the other end of the special-shaped bar 3 can be only set in the first limiting groove 11 of the other support member 1.

[0046] It can be seen that if at least one end of the special-shaped row 3 is located in the first limit groove 11 and the second limit groove 12 at the same time, since the special-shaped row 3 is supported by two grooves, then during the operation of the distribution cabinet 100, even if the special-shaped row 3 is driven by electric force, the first limit groove 11 and the second limit groove 12 of the paired support members 1 can disperse the stress, thereby reducing the damage to the support members 1 caused by the special-shaped row 3 driven by electric force, and further reducing the number of support members 1.

[0047] Continue reading Figures 4 to 5 Further, each of the pair of support members 1 comprises a first side surface 13, and the first side surfaces 13 of the pair of support members 1 face each other. A first limiting groove 11 and a second limiting groove 12 are respectively arranged on the first side surface 13 of each support member 1.

[0048] Continue reading Figure 5 In some embodiments, the second limiting groove 12 may include an inclined surface 121, a first flat surface 122, and a second flat surface 123. The inclined surface 121 may extend inward from the first side surface 13 of the corresponding support member 1, and the inclined surface 121 extends to connect with one side of the first flat surface 122. The second flat surface 123 may extend outward from the other side of the first flat surface 122, and the second flat surface 123 extends to the first side surface 13 of the corresponding support member 1.

[0049] Obviously, in order to facilitate the insertion of the special-shaped row 3 into the second limiting groove 12, the angle between the inclined surface 121 and the corresponding first side surface 13 should be set to an obtuse angle.

[0050] It should be noted that the shape of the second limiting groove 12 can be adjusted according to the shape of the special-shaped row 3. The special-shaped row 3 according to the embodiment of the present disclosure can be a special-shaped row 3 of various shapes currently known or available in the future, and the embodiment of the present disclosure is not limited to this. For example, in some embodiments, the second limiting groove 12 can also include an inclined surface 121, a first straight surface 122 and a second straight surface 123, and the inclined surface 121 can be located between the first straight surface 122 and the second straight surface 123. Of course, in other embodiments, the second limiting groove 12 can also include an arcuate surface, a first straight surface and a second straight surface. The arcuate surface can extend inward from the first side surface 13 of the corresponding support member 1 and be connected to one side of the first straight surface. The second straight surface can extend outward from the other side of the first straight surface to the first side surface 13 of the corresponding support member 1.

[0051] Continue reading Figure 5 In some embodiments, the first limiting groove 11 and the second limiting groove 12 may be spaced apart along the extension direction of the corresponding support member 1. The first limiting groove 11 may be located between adjacent second limiting grooves 12. The second limiting groove 12 may be located between adjacent first limiting grooves 11. Of course, the first limiting groove 11 and the second limiting groove 12 in the same pair may also be interchanged.

[0052] Continue reading Figures 2 to 5 In some embodiments, each of the paired support members 1 is provided with a connection hole 14. The connection member 2 can pass through the connection holes 14 of the paired support members 1 in sequence to lock the paired support members 1. The connection member 2 according to the embodiment of the present disclosure can be various types of connection members 2 currently known or available in the future, and the embodiment of the present disclosure is not limited to this. For example, continue to refer to Figures 3 to 5 In some embodiments, the connecting member 2 may include a bolt 21 and a nut 22. The nut 22 is disposed in the connecting hole 14 of one of the paired supporting members 1, and the bolt 21 may sequentially pass through the connecting hole 14 of the paired supporting members 1 and cooperate with the nut 22 to lock the paired supporting members 1.

[0053] It should be noted that the number of connection holes 14 on each support member 1 may include 5, and a pair of first limiting grooves 11 and second limiting grooves 12 may be provided between adjacent connection holes 14. A connection member 2 is provided in each connection hole 14. Thus, the paired support members 1 can better lock the busbar to prevent the busbar from falling off the paired support members 1.

[0054] It should be noted that the numbers, values, and quantities mentioned above and elsewhere in the present disclosure are exemplary and are not intended to limit the scope of the present disclosure in any way. Any other appropriate numbers, values, and quantities are possible. For example, each support member 1 may be provided with more or fewer connection holes 14, depending on the specific application scenario and requirements.

[0055] Continue reading Figures 3 to 5 Furthermore, the connector 2 may further include an insulating column 23. The insulating column 23 may be arranged around the outer side of the bolt 21, and both ends of the insulating column 23 may be respectively arranged in the corresponding connection holes 14. In order to prevent the insulation distance between the bolt 21 and the electrical component from being less than the safety distance, the insulating column 23 is arranged on the outer side of the bolt 21, so as to avoid conduction between the bolt 21 and the electrical component.

[0056] Figure 6 FIG. 6 is a schematic diagram showing the structure of the back plate 6 according to some embodiments of the present disclosure. Figure 4 and Figure 6 In some embodiments, the plug 7 is connected to the backplane 6. The backplane 6 is provided with a through hole 61, through which the plug 7 can pass. One end of the plug 7 passing through the through hole 61 is connected to the corresponding busbar, and the other end of the plug 7 can be connected to the control circuit, which can be connected to the load.

[0057] Figure 7 FIG. 8 shows a schematic diagram of the cooperation between the back plate 6 and the grille 8 according to some embodiments of the present disclosure. Figure 6 and Figure 7 As shown, in some embodiments, the grille 8 can be arranged on the back plate 6, and the plug 7 can pass through the through hole 61 and the grille 8 in sequence and emerge from the grille 8 to be connected to the corresponding busbar. The grille 8 can cover part of the plug 7 and protect the plug 7 to prevent people from accidentally touching the plug 7. In addition, the present disclosure only needs to arrange the grille 8 at the position of the plug 7, and no grille 8 is required in other places.

[0058] Figure 8 FIG. 8 is a schematic diagram showing the structure of a grille 8 according to some embodiments of the present disclosure. Figures 6 to 8 As shown, in some embodiments, the grille 8 may be provided with a snap-fitting member 81. The back plate 6 may be provided with a snap-fitting groove 62 that cooperates with the snap-fitting member 81 to achieve the connection between the grille 8 and the back plate 6. In other embodiments, the grille 8 may also be provided with a snap-fitting member 81. The back plate 6 may also be provided with a snap-fitting hole that cooperates with the snap-fitting member 81 to achieve the connection between the grille 8 and the back plate 6, which is not limited here. Thus, the grille 8 and the back plate 6 are connected by snap-fitting, which is conducive to reducing costs.

[0059] Return to Reference Figure 6 to Figure 7In some embodiments, the snap-in groove 62 may be disposed outside the through hole 61, and the snap-in groove 62 may be communicated with the through hole 61. Thus, the grille 8 may cover the through hole 61.

[0060] The paired support members 1 according to the embodiment of the present disclosure can be applied to various distribution cabinets 100 to be suitable for rectangular rows and special-shaped rows. It should be understood that the paired support members 1 according to the embodiment of the present disclosure can also be applied to other electrical components, and the embodiment of the present disclosure is not limited to this.
