[0027] To address the problem that metal objects can easily fall into the upper sealing area of ​​the vertical channel inside the drawer-type distribution cabinet in the prior art, this application provides a drawer-type distribution cabinet.

[0028] like Figures 1 to 4 As shown, the drawer-type distribution cabinet includes a cabinet body 10 and a busbar assembly 20. The busbar assembly 20 extends along the height of the cabinet body 10 and is disposed within the cabinet body 10. The busbar assembly 20 includes a first surrounding plate 21, a top plate 22, a bottom plate 23, and a busbar 24. The top plate 22 and the bottom plate 23 are both connected to the first surrounding plate 21 and surround the first surrounding plate 21 to form a receiving cavity 25. The top plate 22 has a busbar mounting portion 221 communicating with the receiving cavity 25. At least a portion of the busbar 24 passes through the busbar mounting portion 221 and extends into the receiving cavity 25. The busbar mounting portion 221 is a through hole, and the through area of ​​the through hole is adjustable.

[0029] Applying the technical solution of this embodiment, the first enclosure plate 21 and the bottom plate 23 form a vertical channel. By setting a top plate 22 on this vertical channel, the upper end of the vertical channel is blocked and shielded, and the busbar 24 is installed on the top plate 22. This prevents metal foreign objects from falling into the vertical channel and causing a short circuit, thus solving the problem in the prior art where metal foreign objects easily fall into the sealed area at the upper end of the vertical channel inside the drawer-type distribution cabinet. At the same time, the busbar mounting part 221 is a through hole, and the through area of ​​the through hole can be adjusted, thereby enabling the installation of busbars 24 of different sizes and specifications, improving the versatility of the busbar assembly 20.

[0030] Optionally, the through-hole includes a plurality of spaced sub-through-holes 2211, with at least two adjacent sub-through-holes 2211 separated by a partition 222. The partition 222 is detachable or peelable, allowing at least two adjacent sub-through-holes 2211 to connect and adjust the passage area of ​​the through-hole. This configuration improves the versatility of the busbar mounting section 221, ensuring that it can accommodate busbars 24 of different sizes and specifications. Simultaneously, this configuration makes adjusting the passage area of ​​the busbar mounting section 221 easier and simpler, reducing the operational difficulty for workers.

[0031] In this embodiment, the top plate 22 includes a top plate body and a partition 222. The partition 222 and the top plate body are integrally formed. When it is necessary to adjust the through area of ​​the through hole, a tool can be used to knock off the partition 222 so that two adjacent sub-through holes 2211 can be connected to increase the through area of ​​the through hole.

[0032] like Figure 3 As shown, the multiple spaced sub-through holes 2211 include a first sub-through hole 2211a and at least one second sub-through hole 2211b. The partition portion 222 includes a first partition portion 2221 and a second partition portion 2222. The first sub-through hole 2211a is separated from the adjacent second sub-through hole 2211b by the first partition portion 2221, and two adjacent second sub-through holes 2211b are separated by the second partition portion 2222. The length of the first sub-through hole 2211a is greater than the length of the second sub-through hole 2211b. This arrangement ensures that the busbar mounting portion 221 has a relatively long first sub-through hole 2211a, and under normal circumstances, the partition portion 222 does not need to be knocked down to meet usage requirements. When a larger busbar 24 needs to be installed, the first partition portion 2221 and the second partition portion 2222 can be selectively knocked down to increase the size of the sub-through hole 2211. Meanwhile, the above-mentioned configuration makes the structural selection of the sub-through hole 2211 and the partition 222 more flexible, so as to meet different usage requirements and working conditions, and also improve the processing flexibility of the workers.

[0033] like Figure 3 As shown, the top plate 22 also has a mounting opening 223. One end of the mounting opening 223 penetrates the top plate 22, and the other end communicates with the busbar mounting portion 221. The busbar 24 is installed into the busbar mounting portion 221 through the mounting opening 223. Specifically, the size of at least a portion of the mounting opening 223 gradually decreases along the direction from the mounting opening 223 to the busbar mounting portion 221. This allows the busbar 24 to be installed into the busbar mounting portion 221 through the mounting opening 223, and the gradual decrease in size of at least a portion of the mounting opening 223 along the installation direction of the busbar 24 guides the busbar 24, ensuring that the busbar 24 is installed into the busbar mounting portion 221 in a predetermined installation direction.

[0034] Specifically, the inner surface of the mounting opening 223 includes two opposing inclined surfaces, the distance between which is the size of the mounting opening 223, so that the structure of the mounting opening 223 is simpler, easier to process and implement, and the processing cost and processing difficulty of the mounting opening 223 are reduced.

[0035] like Figure 2 and Figure 4As shown, the top plate 22 has a side edge with a mounting opening 223. The drawer-type distribution cabinet also includes a structural reinforcement 30. The structural reinforcement 30 has a receiving recess 31, and the side edge extends into and is positioned within the receiving recess 31. This arrangement increases the contact area between the structural reinforcement 30 and the top plate 22, improving the structural strength of the top plate 22 and extending the service life of the drawer-type distribution cabinet.

[0036] In this embodiment, the structural reinforcement 30 is connected to the cabinet body 10 and located between the busbar 24 and the cabinet body 10. This connection between the structural reinforcement 30 and both the cabinet body 10 and the top plate 22 further enhances the structural strength of the top plate 22 and extends the service life of the drawer-type distribution cabinet. Simultaneously, this arrangement makes the spatial layout of the structural reinforcement 30 more rational and compact, improving the space utilization rate of the drawer-type distribution cabinet.

[0037] like Figure 4 As shown, the structural reinforcement 30 includes a second enclosure plate 32 and a first plate body 33. The second enclosure plate 32 is connected to the cabinet body 10 and includes an extension plate 321 and an enclosure plate body 322 connected to each other. The enclosure plate body 322 has an opening; a portion of the extension plate 321 is connected to the enclosure plate body 322 and blocks the opening, while another portion of the extension plate 321 protrudes from the enclosure plate body 322. The first plate body 33 is connected to the extension plate 321 protruding from the enclosure plate body 322, and at least a portion of the first plate body 33 is disposed opposite to the enclosure plate body 322, such that at least a portion of the extension plate 321, at least a portion of the first plate body 33, and the enclosure plate body 322 surround each other to form a receiving recess 31. This arrangement simplifies the structure of the structural reinforcement 30, making it easier to manufacture and implement, and reducing the manufacturing cost and difficulty of the structural reinforcement 30.

[0038] like Figure 4As shown, the enclosure body 322 includes a second plate 3221, a third plate 3222, and a fourth plate 3223. The second plate 3221 is connected to the first end of the extension plate 321. The third plate 3222 is connected to the second plate 3221 and is set at an angle to the second plate 3221. The third plate 3222 is positioned opposite to a portion of the extension plate 321. The fourth plate 3223 is connected to the third plate 3222 and is set at an angle to the third plate 3222. The fourth plate 3223 is positioned opposite to the second plate 3221. An opening is formed around the second plate 3221, the third plate 3222, and the fourth plate 3223. In this configuration, the end of the fourth plate 3223 furthest from the third plate 3222 abuts against the extension plate 321. The second end of the extension plate 321 protrudes from the fourth plate 3223 and is connected to the first plate 33, forming a receiving recess 31 around the fourth plate 3223. This arrangement simplifies the structure of the enclosure body 322, making it easier to manufacture and implement, and reducing the manufacturing cost and difficulty of the enclosure body 322.

[0039] In this embodiment, the second plate 3221 and the third plate 3222 are arranged perpendicularly to each other, the third plate 3222 and the fourth plate 3223 are arranged perpendicularly to each other, and the extension plate 321 and the third plate 3222 are arranged parallel to each other. The extension plate 321 has a mounting hole 3211, and fasteners are passed through the mounting hole 3211 and the cabinet body 10 to connect the structural reinforcement 30 and the cabinet body 10.

[0040] Optionally, there is one mounting hole 3211; or there are multiple mounting holes 3211, which are spaced apart along the length and / or height of the structural reinforcement 30.

[0041] like Figure 4 As shown, the first plate 33 includes a first plate segment 331 and a second plate segment 332 that are bent sequentially. The first plate segment 331 is connected to the second end of the extension plate 321, and the second plate segment 332 is located on the side of the first plate segment 331 away from the surrounding plate body 322. This arrangement simplifies the structure of the first plate 33, making it easier to process and implement, and reducing the processing cost and difficulty of the first plate 33. Optionally, the first plate segment 331 and the second plate segment 332 are arranged perpendicular to each other.

[0042] In this embodiment, the second enclosure plate 32 and the first plate 33 are integrally formed. This arrangement makes the structural reinforcement 30 an integral structure, which not only reduces the processing cost and difficulty of the structural reinforcement 30, but also improves its structural strength and extends its service life.

[0043] In this embodiment, the structural reinforcement 30 is formed by bending sheet metal.

[0044] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0045] The drawer-type distribution cabinet includes a cabinet body and a busbar assembly. The busbar assembly extends along the height of the cabinet body and is disposed within the cabinet body. The busbar assembly includes a first enclosure plate, a top plate, a bottom plate, and a busbar. The top plate and bottom plate are both connected to the first enclosure plate and surround the first enclosure plate to form a receiving cavity. The top plate has a busbar mounting part communicating with the receiving cavity. At least a portion of the busbar passes through the busbar mounting part and extends into the receiving cavity. In this way, the first enclosure plate and the bottom plate surround to form a vertical channel. By setting the top plate on this vertical channel to block and shield the upper end of the vertical channel, and with the busbar mounted on the top plate, it is possible to prevent metal foreign objects from falling into the vertical channel and causing a short circuit. This solves the problem in the prior art where metal foreign objects easily fall into the upper end of the vertical channel sealed inside the drawer-type distribution cabinet. At the same time, the busbar mounting part is a through hole, and the through-area of ​​the through hole can be adjusted, thereby enabling the installation of busbars of different sizes and specifications, improving the versatility of the busbar assembly.
