[0021] 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 of 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.
[0022] See also Figure 1-3The utility model provides a technical solution: a high-safety high-voltage switch cabinet, comprising a switch cabinet body 1, a mounting component for facilitating the installation of cables is arranged at the back of the switch cabinet body 1, the mounting component comprises a junction box 2 fixedly arranged at the back of the switch cabinet body 1, a plurality of first wiring holes 3 are arranged at the bottom of the junction box 2, a second wiring hole 4 which is connected with the switch cabinet body 1 is arranged on the inner wall of the junction box 2, a tightening component for fixing the cables is also arranged inside the junction box 2, elastic waterproof rings are arranged in the first wiring hole 3 and the second wiring hole 4, which can ensure the sealing of the wiring hole part when the cables are installed, prevent the external water vapor from entering the junction box 2, and improve the safety of the cables in the junction box 2.
[0023] The wire tightening component includes a wire threading plate 5 fixedly arranged inside the junction box 2, a rectangular through groove is provided in the middle part of the wire threading plate 5 for convenient cable passage, a wire pressing rod 7 is provided on the inner wall of the rectangular through groove for horizontal sliding, a sliding groove is also provided on the side wall of the rectangular through groove for convenient movement of the wire pressing rod 7, a rotating rod 8 is rotatably connected to the side wall of the wire pressing rod 7, and the rotating rod 8 passes through the wire threading plate 5 and is screwed together with the wire threading plate 5 by a thread.
[0024] A plurality of limiting rings 6 for limiting the position of the cables are also provided in the rectangular through groove. The limiting rings 6 are specifically made of elastic material and are fixedly connected to the inner wall of the rectangular through groove and the side wall of the wire pressing rod 7 respectively. The limiting rings 6 can classify and isolate one or more strands of cables, thereby avoiding the entanglement of the cables and facilitating the subsequent cable installation or maintenance. At the same time, the limiting rings 6 protect the cables and can prevent the wire pressing rod 7 from directly squeezing and causing cable damage.
[0025] An extrusion strip 9 is also provided on the inner wall of the limiting ring 6. The extrusion strip 9 is specifically made of silicone material, and the cross-section of the extrusion strip 9 is a semicircular structure. When the cable passes through the limiting ring 6, the extrusion strip 9 can exert a certain amount of extrusion on the cable, thereby preventing the cable from being too loose and inconvenient to install. At the same time, when the cable is disassembled, after the rotating rod 8 is loosened, the extrusion strip 9 can also limit the cable to prevent the cable from falling directly from the limiting ring 6.
[0026] Working principle: During use, when installing the cable, first pass the cable through the first wiring hole 2 at the bottom of the junction box 2, then continue to pass the cable through the limiting ring 6, and then pass through the second wiring hole 2 to the switch cabinet body 1, and then rotate the rotating rod 8 to push the wire pressing rod 7 to move until the limiting ring 6 is squeezed, so that the limiting ring 6 is deformed until the cable is compressed to complete the fixation of the cable, thereby effectively protecting the cable, and being able to classify the cables, which is convenient for subsequent disassembly and maintenance.
[0027] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
