[0026] Reference Figure 1 And Figure 2Preferably, the distribution box body 10 further comprises a distribution box bottom plate 13 and a distribution box back plate 14, the distribution box back plate 14 is connected to the side edges of the two opposite distribution box side plates 11, the bottom of the distribution box side plates 11 and the distribution box back plate 14 is connected to the distribution box bottom plate 13, and the top of the distribution box side plates 11 and the distribution box back plate 14 is connected to the brim 20.

[0027] Referring to Figure 2 Preferably, one side of the distribution box back plate 14 of the distribution box body 10 is provided with an opening, and a box door 15 is rotatably installed at the opening. It should be noted that the box door 15 not only improves the operation convenience, but also provides more space for the installation and maintenance of internal components. The box door 15 of the present application is provided with a sealing rubber ring around the inner side, which realizes the waterproofness of the box body. The box door 15 of the present application is provided with a handle on the outer side, and a logo setting position 16 and a card groove 17 are respectively arranged at the two corners of the top of the outer side of the box door 15. The card groove 17 is used to place data cards for easy viewing.

[0028] Referring to Figure 3 Preferably, the brim 20 comprises a brim bottom plate 21 and two connected slope plates 22, the slope plates 22 and the circumferential side of the brim bottom plate 21 are connected to the connecting plates, one side of the brim bottom plate 21 is flush with the distribution box back plate 14, and the other side of the brim bottom plate 21 protrudes from one side of the box door 15 of the distribution box body 10. The brim 20 provides an additional protective layer for the distribution box, and the two connected slope plates 22 effectively guide the rainwater and dust and other impurities outwards, avoiding the influence of the external environment on the inside of the box body. The extension design of the brim 20 further provides protection to prevent excessive rainwater from splashing to the box door 15 in rainy days.

[0029] Further, the brim bottom plate 21 is provided with air holes 23, and the part of the brim bottom plate 21 protruding from the box door 15 of the distribution box body 10 is provided with heat dissipation holes 24. When the internal heat is too much, the hot air reaches the inside of the brim 20 through the air holes 23, and then is discharged from the inside of the brim 20 through the heat dissipation holes 24, which is beneficial to the circulation and heat dissipation of the air inside the distribution box. At the same time, because the heat dissipation holes 24 are located in the part of the brim bottom plate 21 protruding from the box body, this position is not easy to be directly invaded by rainwater. In addition, the extension part of the brim 20 forms a natural shelter, further reducing the risk of the heat dissipation holes 24 being affected by rainwater or other environmental factors, maintaining the dryness of the inside of the box body and the safety of the electrical equipment.

[0031] Further, the heat dissipation holes 24 are provided with dustproof screens. The dustproof screens effectively prevent dust, insects and other small particles from entering the interior of the distribution box, avoiding the situation that the internal elements are affected by dust accumulation and cause heat dissipation efficiency or failure. The design of the dustproof screen also makes the distribution box more adaptable in complex environments, reduces maintenance requirements, and improves the overall performance and durability of the distribution box.

[0032] Referring to Figure 1 Preferably, the distribution box back plate 14 is provided with mounting holes. The mounting holes on the distribution box back plate 14 facilitate the fixation of the distribution box on the wall or support through bolts, which is simple and stable to install.

[0033] Referring to Figure 5 and Figure 6 Preferably, the plugging member 34 is a circular truncated cone plugging member 34, and the outer side wall of the circular truncated cone plugging member 34 is provided with a plugging member 34 annular protrusion, and the connecting hole 32 is provided with a connecting hole 32 annular groove which is threadedly matched with the plugging member 34. It should be noted that when the partition joint 30 is not connected to the adjacent distribution box, the partition joint 30 is inserted into the knock-out hole 12, and at this time the connecting hole 32 of the partition joint 30 can be closed by the circular truncated cone plugging member 34, thereby reliably closing the knock-out hole 12, preventing dust, water vapor and other external substances from entering the interior of the box through the knock-out hole 12 on the side, and further improving the protection level of the box. The design of the circular truncated cone plugging member 34 also enhances the sealing effect of the plugging member 34, avoids the problem of reduced air tightness due to loosening or falling off, and the matching of the plugging member 34 annular protrusion and the connecting hole 32 annular groove also facilitates installation and disassembly, ensuring the service life of the distribution box in various environments and the safety of the internal elements. It should be noted that the circular truncated cone plugging member 34 is a plastic circular truncated cone plugging member 34.

[0034] It should be noted that the power distribution box of the present application is convenient to splice. First, by aligning the knock-out holes 12 of adjacent power distribution boxes, the partition joint 30 is inserted between the aligned knock-out holes 12 of the two adjacent power distribution boxes, and the locking nut 36 is fixed to the outside of the joint through the external thread structure. In this way, the two power distribution boxes can be stably fixed on the same horizontal line to form a neat arrangement layout. The two ends of the partition joint 30 are provided with through connecting holes 32, which allow the cable to pass from one power distribution box to the next power distribution box, avoiding the complex process of independent threading of multiple wire slots. The number of knock-out holes 12 can be flexibly reserved according to actual needs to adapt to different cable connection needs. In addition, the waterproof rubber pads 35 provided on the partition joint 30 ensure that the spliced part still maintains good sealing after the cable passes through, thereby achieving waterproof effect in the splicing area. In the present application, the waterproof rubber pads 35 are preferably provided in three, two of which are provided on the inner side of the knock-out holes 12 of the two power distribution boxes, and the remaining one is provided between the two power distribution boxes. The setting of the waterproof rubber pads 35 not only increases the connection tightness between the power distribution boxes, but also ensures the air tightness and safety in outdoor environment, providing protection for the stable operation of the power distribution system.

[0035] The utility model provides a kind of power distribution box convenient to splice, first, by being provided knock-out hole 12 in power distribution box side plate 11 bottom, and knock-out hole 12 is detachably installed partition joint 30, when multiple power distribution boxes need to be installed side by side in same area, just align the knock-out hole 12 position of adjacent power distribution boxes, insert partition joint 30 and be fixed by locking nut 36, can realize firm splicing. In this way, not only splicing process is simplified, but also without remaining complex operation, improve installation efficiency. In addition, waterproof rubber pad 35 on partition joint 30 forms effective sealing after adjacent power distribution box splicing, prevents moisture from entering box, ensures the safety of electrical element in box. Meanwhile, the through design connecting hole 32 on partition joint 30 is used to pass through cable, it is convenient for cable to be directly threaded between adjacent power distribution boxes, avoid the exposed problem of wire slot in traditional power distribution box wiring, make wiring neat and beautiful, reduce the security risk caused by cable exposure. In addition, the design of plugging piece 34 seals knock-out hole 12 when partition joint 30 is not used for splicing, prevents rainwater etc. from entering, keeps inside box dry, prolongs service life. Therefore, the power distribution box convenient to splice has remarkable advantages in simplifying splicing process, enhancing waterproof sealing effect and optimizing wiring etc.
