The bundled wiring structure of low-voltage switchgear can meet the wiring needs of different equipment, ensuring clear and orderly wiring connections between devices, improving the stability and maintainability of the production system, and guaranteeing smooth production operations.

[0003] However, the wiring structure of existing low-voltage switchgear requires fixing each wire harness individually, which is not convenient for fixing multiple wire harnesses at once. This makes the fixing process extremely cumbersome, as each wire harness must be positioned and installed separately. This not only consumes a lot of time and effort, but also makes it easy to make operational errors, reducing fixing efficiency and thus slowing down the overall assembly progress of the low-voltage switchgear.

[0023] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] Reference Figure 1 and Figure 2 This utility model provides an embodiment of a low-voltage switchgear wiring structure, including a U-shaped frame 1. A fixing post 2 is fixedly connected inside the U-shaped frame 1. A fixing block 4 is fixedly connected to the outer wall of the fixing post 2. A wire bundle tube 5 is fixedly connected to the outer wall of the fixing block 4. A sliding post 3 is slidably connected inside the U-shaped frame 1. A fixing block 6 is fixedly connected to the outer wall of the sliding post 3. A wire bundle tube 7 is fixedly connected to the outer wall of the fixing block 6. The outer wall of the wire bundle tube 7 is in contact with the outer wall of the wire bundle tube 5. The fixing block 6 is slidably connected to the outer wall of the fixing post 2. Limiting blocks 10 are fixedly connected to both ends of the sliding post 3. Limiting blocks 8 are fixedly connected to the outer wall of the sliding post 3. A spring 9 is slidably connected to the outer wall of the sliding post 3. One end of the spring 9 is fixedly connected to the inner wall of the U-shaped frame 1, and the other end of the spring 9 is fixedly connected to the end of the limiting block 8 away from the fixing block 6. An installation assembly is provided on the outer wall of the U-shaped frame 1.

[0025] Specifically, the U-shaped frame 1 can fix the fixed post 2, the fixed post 2 can fix the fixed block 4, the fixed block 4 can fix the cable bundle 5, the sliding post 3 can fix the fixed block 6, the fixed block 6 can fix the cable bundle 7, the limiting block 8 can limit the spring 9, and the spring 9 can reset the sliding post 3. The mounting assembly is used to install the structure into the required position in the low-voltage switchgear.

[0026] Reference Figure 1 and Figure 2 The installation components include a fixing block 3 11, the outer wall of which is fixedly connected to the outer wall of the U-shaped frame 1, the inner wall of which is fixedly connected to a fixing column 2 12, the outer wall of which is rotatably connected to a mounting bracket 13, and the upper surface of the mounting bracket 13 is fixedly connected to a mounting lug 14.

[0027] Specifically, the mounting assembly is used to install the structure into the required position inside the low-voltage switchgear. During use, the mounting bracket 13 can be fixed to the inside of the low-voltage switchgear using bolts and mounting lugs 14.

[0028] Reference Figure 2 and Figure 4 The outer wall of the mounting bracket 13 is provided with a sliding groove 15, and the outer wall of the fixing block 3 11 is fixedly connected with a sliding column 2 16, and the outer wall of the sliding column 2 16 is slidably connected to the inner wall of the sliding groove 15.

[0029] Specifically, during the process of adjusting the angle of the fixed block 11 by the fixed column 2 12, the sliding column 2 16 fixedly connected to the outer wall of the fixed block 11 will slide in the inner wall of the sliding groove 15 opened on the outer wall of the mounting bracket 13, which can improve the stability of the fixed block 11 during rotation.

[0030] Reference Figure 1 , Figure 3 and Figure 4 Support block 17 is fixedly connected to the outer wall of mounting bracket 13, and support block 28 is fixedly connected to the outer wall of mounting bracket 13; worm gear 19 is rotatably connected inside support block 17, and the outer wall of worm gear 19 is rotatably connected to the inside of support block 28; worm wheel 21 is meshed with the tooth end of worm gear 19, and the inner wall of worm wheel 21 is fixedly connected to the outer wall of fixed column 22; handwheel 20 is fixedly connected to the outer wall of worm gear 19; the outer wall of fixed block 31 is connected to the inner wall of mounting bracket 13.

[0031] Specifically, through the cooperation between the worm gear 19 and the worm wheel 21, precise fine-tuning of the angles of the first cable bundle 5 and the second cable bundle 7 can be achieved. According to different wiring requirements, the first cable bundle 5 and the second cable bundle 7 can be accurately adjusted to the required angle, ensuring that the cable bundle routing meets the design requirements. Moreover, this transmission method has good self-locking performance. The worm wheel 21 can only be rotated by rotating the worm gear 19, which in turn causes the second fixing post 12 to rotate inside the mounting bracket 13. The worm gear 19 cannot be rotated by rotating the worm wheel 21. After the cable bundle is adjusted to the correct position, it can effectively prevent it from rotating on its own due to gravity or other external forces, thereby improving the reliability of the cable bundle structure and ensuring that the cable bundle always maintains the correct position and routing during the operation of the switch cabinet.

[0032] Working principle: During use, bolts are used to fix the mounting bracket 13 to the inside of the low-voltage switchgear using the mounting lugs 14. When multiple wire harnesses need to be fixed simultaneously, simply push the limit block 10 to make the sliding column 3 slide inside the U-shaped frame 1, which in turn moves the fixing block 6, causing the wire harness tube 7 to release the contact between the wire harness tubes 5. As the sliding column 3 slides inside the U-shaped frame 1, it will move the limit block 8, causing the spring 9 to contract and slide against the outer wall of the sliding column 3. Then, the wire harness is placed into the wire harness tube. Between cable bundle 15 and cable bundle 27, after multiple cable bundles are placed, the limiting block 210 is no longer pushed. This causes the spring 9, which is in a contracted state, to rebound and reset, pushing the limiting block 18 to drive the sliding column 13 to reset and slide inside the U-shaped frame 1. This causes the fixing block 26 to move in the opposite direction and slide on the outer wall of the fixing column 2 to reset to a state of contact with the cable bundle 15, thus fixing multiple cable bundles. This achieves the effect of fixing multiple cable bundles at once, allowing for the positioning and installation of multiple cable bundles in one go. This reduces the tedious steps of fixing cable bundles one by one, saves installation time, and improves overall assembly efficiency.

[0033] When it is necessary to adjust the operating angle of cable bundle 5 and cable bundle 7, simply turn the handwheel 20 to cause the worm gear 19 to rotate inside the support block 18 and support block 17. When the worm gear 19 rotates, it will drive the worm wheel 21 to rotate, which in turn will drive the fixing post 12 to rotate inside the mounting bracket 13. This will cause the fixing block 11 to drive the U-shaped frame 1 to rotate, thereby adjusting the operating angle of cable bundle 5 and cable bundle 7. This achieves the effect of adjusting the operating angle of cable bundle 7 and cable bundle 5. According to the specific shape, size and distribution of electrical components of the cabinet, the direction and position of the cable bundle can be flexibly changed to better adapt to the complex internal space and achieve the optimal layout of the cable bundle in a limited space.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
