Description

Technical Field

[0001] This utility model relates to the field of power technology, specifically to a distribution box with a sealing device. Background Technology

[0002] Distribution boxes are constantly exposed to sun and rain. The side walls of the distribution box have inlet / outlet holes through which cables pass, connecting the external circuitry to the internal circuitry. Current technology uses simple sealing rings that fit into the side walls, which are prone to detachment. Therefore, rainwater easily seeps into the cable inlet / outlet holes, causing switches inside the box to burn out. This has led to frequent large-scale power outages. Furthermore, the cable insulation layer is worn down by wind and the metal edges of the inlet / outlet holes, exposing the cable and causing it to come into contact with the cabinet. Cases of electric shock caused by this, where the entire cabinet becomes electrified, are also frequently reported. Utility Model Content

[0034] Example 1

[0035] This embodiment provides a distribution box with a sealing device, as shown in the attached document. Figures 1-3 As shown, it includes:

[0036] The main body 11 is provided with a connecting pipe 111, which connects the inside and outside of the main body 11. Cables can pass through the connecting pipe 111 and enter the main body 11.

[0037] The sealing element 12 has a first through hole 121 and a second through hole 122. The diameter of the first through hole 121 is larger than the diameter of the second through hole 122. The central axis of the first through hole 121 and the central axis of the second through hole 122 are coaxial. The sealing element 12 is fitted onto the connecting pipe 111, with the inner wall of the first through hole 121 fitting against the outer wall of the connecting pipe 111. The second through hole 122 mates with the cable, and the sealing element 12 is also fitted onto the outer wall of the cable, with the inner wall of the second through hole 122 fitting against the outer wall of the cable. The cable passes through the second through hole 122, the first through hole 121, and the connecting pipe 111, extending into the main body 11, thus creating an electrical connection between the external circuit and the internal circuit of the enclosure.

[0038] The fastening assembly secures the seal 12, connecting pipe 111, and cable, forming a fixed connection to prevent detachment. The connecting pipe 111 increases the contact area between the cable and the main body 11. Furthermore, the seal 12 is connected and fixed at one end to the connecting pipe 111, creating a seal, and at the other end to the cable, creating a double seal. This improves the sealing level, enhances the insulation protection of the incoming and outgoing cables, and effectively prevents the enclosure from becoming electrified.

[0039] Specifically, as shown in the attached document Figures 2-3As shown, the seal 12 includes an upper part 123 and a lower part 124. A first through hole 121 is provided in the upper part 123, and a second through hole 122 is provided in the lower part 124. Here, the cross-sectional area of ​​the upper part 123 is larger than that of the lower part 124, forming a bowl-shaped structure. There are two sets of fastening components, which respectively mate with the outer walls of the upper part 123 and the lower part 124. This structural arrangement of the seal 12 forms a bowl-like structure, improving the sealing effect. One set of fastening components achieves the fastening effect between the seal 12 and the connecting pipe 111, while the other set achieves the fastening effect between the seal 12 and the cable. Alternatively, the seal 12 can also be cylindrical, which can be adjusted according to actual needs by those skilled in the art.

[0040] Specifically, as shown in the attached document Figures 2-3 As shown, in the first state, the outer wall of the seal 12 is disconnected; specifically, the outer wall of the seal 12 can be separated, meaning the seal 12 can be opened to form a long strip structure. In the second state, the disconnected portion of the outer wall of the seal 12 is closed; the second state means that the seal 12 forms a ring structure, with the two ends of the long strip closed (i.e., the disconnected portion is closed). After the connecting pipe 111 and the cable are fixed, the seal 12 can be secured by wrapping it from the side, eliminating the need for the operator to disassemble the cable and reducing installation difficulty.

[0041] Specifically, as shown in the attached document Figures 2-3 As shown, the outer wall of the seal 12 has a stepped groove 125 and a stepped protrusion 126 at the break point. In the second state, the stepped groove 125 and the stepped protrusion 126 are in contact. The cooperation between the stepped groove 125 and the stepped protrusion 126 creates a misaligned fit, preventing a large gap from forming after the break point overlaps. This misalignment improves the sealing effect. Specifically, when the seal 12 is unfolded, it forms a long strip structure. One end of the strip has a stepped groove 125, and the other end has a stepped protrusion 126. When the seal 12 forms a ring structure, the stepped groove 125 and the stepped protrusion 126 cooperate. When the fastening assembly is tightened, the stepped groove 125 and the stepped protrusion 126 can abut against each other, or they can deform under stress after abutting against each other, thus increasing the sealing effect.

[0042] Specifically, as shown in the attached document Figures 2-3 As shown, the inner wall of the first through hole 121 is provided with several stepped grooves 127. The stepped grooves 127 are suitable for different diameters of connecting pipes 111, forming a universal effect.

[0043] Specifically, as shown in the attached document Figures 1-3As shown, the fastening assembly includes a cable tie 13, a fastening sleeve 14, and a fastening bolt 15. The fastening sleeve 14 is connected to the cable tie 13, and the fastening bolt 15 passes through the fastening sleeve 14 to adjust the diameter of the fixing ring formed by the cable tie 13. The cable tie 13 is fitted onto the outer wall of the seal 12. Here, the cable tie 13 forms a ring structure, which is a fixing ring structure. The cable tie 13 is located outside the seal 12, forming a fastening effect. By cooperating with the fastening bolt 15, the tightness of the cable tie 13 can be adjusted to achieve the fixing effect of the seal 12. Here, there are two cable ties 13, corresponding to the upper part 123 and the lower part 124 of the seal 12, respectively.

[0044] Specifically, the cable tie 13 is made of stainless steel. Here, the fastening bolt 15 cooperates with the fastening sleeve 14 and the cable tie 13 to achieve a binding effect. In this embodiment, the fastening bolt 15 and the cable tie 13 can form a threaded connection, creating a movement effect for the cable tie 13. Alternatively, the cable tie 13 can also be made of plastic, with a barbed structure to achieve a binding effect.

[0045] Specifically, the seal 12 is integrally molded. The material of the seal 12 can be rubber.

[0046] Specifically, as shown in the attached document Figure 1 As shown, the open end of the connecting pipe 111 faces downwards. The arrangement of the connecting pipe 111 forms a downward structure, creating a protective effect. When rainwater falls, it will also move downwards along the connecting pipe 111. When the accumulated water exceeds the opening of the connecting pipe 111, the sealing element 12 can also form a sealing and protective effect, preventing water from entering the box through the connecting pipe 111.

[0047] Specifically, the connecting pipe 111 is bent. The bending design makes processing more convenient. The connecting pipe 111 and the body 11 can be integrally formed or fixed by welding.

[0048] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
