Technical Field

[0001] The utility model relates to the technical field of composite distribution boxes, in particular to a novel wire passing structure of a composite distribution box. Background Art

[0002] According to the requirements of GB / T 3836.2-2021, the cables in the explosion-proof distribution box cannot be suspended in the wire-passing structure and must be fixed with a sealing structure to meet the use requirements. Figure 4 As shown, existing distribution boxes usually use a cylindrical wire-passing structure. When fixing the cable in this design, it is usually necessary to fill glue on both sides of the wire-passing barrel multiple times, which is a cumbersome operation. At the same time, the seal also needs to meet the following standards:

[0003] During installation, the minimum filler length of the cable should be 20mm. When multiple new wires pass through the filler, these new wires should meet the 20mm sealing filler length, and at least 20% of the cross-sectional area at each point should be filled with filler. Utility Model Content

[0004] The utility model aims to provide a novel wire-passing structure of a composite distribution box, so as to solve the problem that the sealing and fixing of cables in the wire-passing structure are complicated in the past.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a new wire-passing structure of a composite distribution box, the composite distribution box comprising a first chamber and a second chamber, the first chamber and the second chamber being separated by a partition plate, a wire-threading opening being provided on the partition plate, a cover shell being respectively installed on both sides of the partition plate, and the wire-threading opening being placed in the cover shell.

[0006] Preferably, the number of the threading openings is two, and the two threading openings are respectively arranged at two feet of the bottom surface of the partition plate.

[0007] Preferably, the height of the cover shell is higher than the threading opening.

[0008] Preferably, a first mounting edge is provided at the edge of the composite distribution box.

[0009] Preferably, a second mounting edge is provided at the edge of the partition plate.

[0010] Preferably, mounting screw holes are provided on the first mounting edge and the second mounting edge.

[0011] The utility model also provides another technical solution: the number of the threading openings is several, and the threading openings are evenly distributed at the bottom of the partition plate.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] By setting the threading port connecting the two chambers on the bottom surface of the partition plate, and setting a cover capable of holding gel on both sides of the threading port, the threading and fixing process of the entire distribution box can be completed quickly. This design method can solve the problem of complicated cable fixing in the threading port of the existing explosion-proof distribution cabinet.

[0014] And according to the requirements of GB / T 3836.2-2021, the sealing length of the glue filling is 20mm, and at least 20% of the cross-sectional area of ​​each cable at each point is filled with filler. By pouring glue into the cover, it is easier to fix the cable, reducing the operation time of the staff and achieving a convenient and quick effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-2The utility model provides a technical solution: a new wire-passing structure of a composite distribution box, wherein the composite distribution box 1 includes a first chamber 2 and a second chamber 3, which play the role of explosion-proof and installation of electrical components. The first chamber 2 and the second chamber 3 are separated by a partition plate 4, and a threading opening 5 is provided on the partition plate 4. The number of the threading openings 5 ​​is two, and the two threading openings 5 ​​are respectively arranged at the two feet of the bottom surface of the partition plate 4. The threading openings 5 ​​opened in this way make it easier to cut on the partition plate 4, and each threading opening 5 only needs to be cut twice. Instead of cutting multiple times like other hole opening methods.

[0022] The two sides of the partition plate 4 are respectively provided with a cover 6, and the threading port 5 is placed in the cover 6. The height of the cover 6 is higher than the depth of the threading port 5, so that when the cable passes through the threading port 5, it is convenient to directly fill the cover 6 with glue so that the glue does not cover the cable. At the same time, the minimum filler length of the cable should be 20mm. When multiple strands of new wires pass through the filler, these new wires should meet the 20mm sealing filler length, and at least 20% of the cross-sectional area at each point should be filled with filler.

[0023] In order to facilitate the overall installation of the composite distribution box 1, a first installation edge 7 is provided at the edge of the composite distribution box 1. A second installation edge 8 is provided at the edge of the partition plate 4. The first installation edge 7 and the second installation edge 8 are provided with installation screw holes 9.

[0024] Working principle: According to general standards, explosion-proof distribution boxes are not allowed to be directly introduced into the explosion-proof cavity. Explosion-proof distribution boxes are usually divided into two cavities, one is the explosion-proof cavity, which is equipped with electrical components (such as circuit breakers, leakage protection, instruments, etc.), and the other cavity is installed with wiring terminals, indicator lights, etc.

[0025] The cables between the electrical components and the indicator lights and other equipment are passed through the threading port 5, and the glue is filled between the covers 6 on both sides. According to the national standard, the distance that the glue covers the cables is greater than 20mm or 25mm. During the glue filling process, the operator only needs to inject the glue into the cover 6 so that the glue is filled between the cables, which is very convenient to operate.

[0026] See also Figure 3 The utility model also provides another technical solution, which is different from the above technical solution in that: the number of the threading openings 5 ​​is several, and the threading openings 5 ​​are evenly distributed at the bottom of the partition plate 4. The other technical features remain unchanged. According to the installation of the electrical components in the composite distribution box 1, the opening position and size of the threading openings 5 ​​are adjusted to meet the actual wiring needs.

[0027] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.

[0028] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
