Description

Technical Field

[0001] This utility model belongs to the field of switch cabinet technology, specifically relating to a cable fixing device inside a switch cabinet. Background Technology

[0002] Switchgear is a crucial device in power systems used for controlling, protecting, and monitoring electrical equipment. It is widely used in substations, distribution rooms, and power distribution systems in industrial and mining enterprises. Inside switchgear, a large number of cables are typically laid to connect different electrical components, enabling the transmission of electrical energy and signals. Due to the limited space inside the switchgear, cable routing must be compact, neat, and easy to maintain; therefore, high requirements are placed on the cable fixing methods.

[0003] Currently, cables are typically secured inside switchgear using cable ties, clips, or brackets. However, these methods have several drawbacks: First, traditional cable securing methods lack proper separation design, leading to cables easily becoming tangled, hindering maintenance and repair, and making it difficult to quickly locate the correct cable. Second, cables may be compressed or bent during the securing process, potentially affecting their lifespan or even causing damage and disrupting the normal operation of electrical equipment. Third, some securing devices are inconvenient to install or remove cables, lacking quick-assembly and disassembly structures, resulting in low construction efficiency. Furthermore, existing cable securing devices exhibit poor stability when securing single or multiple cables, failing to effectively prevent loosening or displacement due to external forces during operation. Utility Model Content

[0004] To address the problems existing in the prior art, the purpose of this utility model is to provide a cable fixing device for switch cabinets. This device achieves adjustable installation through the cooperation of a T-shaped sliding groove and a pressing slider; it uses multiple cable separation holes to independently separate cables, preventing cable tangling and improving maintenance efficiency; and it uses a fan-shaped structure to centrally arrange cables, reducing cable bending angles and thus minimizing cable damage. Furthermore, this device includes a fan-shaped sealing plate to seal and fix the cable ends, and, combined with the pressing plate, provides additional fixing force to improve cable stability.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A cable fixing device for a switch cabinet includes a cabinet body with a door hinged to the front. Rails are evenly and horizontally fixed to the inner side of the cabinet body, and electrical components are evenly mounted on the surface of the rails. Multiple cable outlets are evenly arranged at the bottom of the cabinet body. A raised strip is horizontally fixed to the lower interior of the cabinet body, and a T-shaped groove is formed on the surface of the raised strip. A pressing slider is slidably installed inside the T-shaped groove. An extension platform is provided on the front side of the pressing slider, extending beyond the front surface of the raised strip. Locking knobs are symmetrically screwed onto both sides of the pressing slider surface, and the pressing slider is locked in place by the two locking knobs. A fan-shaped fixing box is provided on the front side of the extension platform, with its front open. A cable collection tube is provided at the bottom of the fan-shaped fixing box, corresponding to the cable outlets. Cable separation holes are evenly formed on the curved surface of the top of the fan-shaped fixing box, with their front open. The cable separation holes are used to isolate cables, and the cables pass downwards through the cable collection tube.

[0007] Furthermore, mounting plates are symmetrically arranged above the front surface of the cable tray, and a rotating shaft is rotatably installed between the two mounting plates. A fan-shaped sealing plate is provided on the top of the rotating shaft. The fan-shaped sealing plate is placed on the front side of the fan-shaped fixing box and the two are compatible. The fan-shaped sealing plate seals the open front ends of the multiple cable separation holes.

[0008] Furthermore, a swing plate is provided at the bottom of the rotating shaft, and a hollow groove is opened on the surface of the swing plate. A fixing bolt is welded to the front surface of the cable drum, and the fixing bolt passes through the hollow groove.

[0009] Furthermore, a spring is fitted onto the surface of the fixing bolt, and the spring is positioned between the swing plate and the cable drum.

[0010] Furthermore, an adjusting nut is screwed onto the surface of the spring, and the adjusting nut is located on the front side of the swing plate.

[0011] Furthermore, a rotating screw is rotatably inserted below the front surface of the cable tray, and a pressing plate is screwed onto one end of the rotating screw. The pressing plate is placed inside the cable tray, and a concave surface is provided on the rear side of the pressing plate. The concave surface presses and fixes the cable inside the cable tray.

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

[0013] Firstly, in traditional switchgear cable fixing methods, cables often become tangled due to a lack of proper separation and fixing design, increasing the difficulty of maintenance. By setting multiple cable separation holes, cables can be effectively isolated and classified, preventing them from tangling and facilitating quick identification of cables during switchgear maintenance. This design results in a neater cable arrangement, providing maintenance personnel with a more efficient and convenient maintenance experience, and solving the problem of messy cables in existing systems.

[0014] Secondly, existing cable fixing methods often fail to effectively prevent cable damage due to bending or compression, especially under high temperature, high pressure, or long-term operating environments, where excessive bending or compression can lead to performance degradation or damage. This device seals the open ends of multiple cable separation holes using a fan-shaped sealing plate, reducing the impact of external forces on the cables. Simultaneously, the combination of a fan-shaped fixing box and a cable collection drum collects and guides multiple cables above, reducing the bending angle during fixing and further preventing damage caused by excessive bending, effectively extending the cable's service life.

[0015] Furthermore, existing cable fixing devices are inconvenient to install or remove, often resulting in insecure fixing or difficulty in disassembly. This new device employs a structure combining a T-shaped slide groove and a pressing slider, along with a locking knob, allowing for quick adjustment and fixation of the device's position. This ensures stability during use and avoids the instability caused by loosening in traditional fixing methods. In addition, the design of a rotating screw and pressing plate allows for precise adjustment of the cable fixing force, making operation more convenient and flexible, and improving the device's practicality and stability.

[0016] Finally, a common problem with existing cable fixing devices is that they are not securely fixed, and the external environment may affect the cables, such as causing the connections to loosen when the cables are pulled. This device uses a compression plate and its concave surface to compress and fix the cables after installation, preventing external pulling from causing the connections to loosen, thereby improving the stability of the cables and ensuring the safety of the internal circuitry of the switch cabinet.

[0026] refer to Figures 1-6 As shown, a cable fixing device inside a switch cabinet includes a cabinet body 1. A cabinet door 4 is hinged to the front of the cabinet body 1. Track rods 2 are evenly and horizontally fixed inside the cabinet body 1. Electrical components 3 are evenly installed on the surface of the track rods 2. Multiple cable outlet tubes 101 are evenly arranged at the bottom of the cabinet body 1 for facilitating cable output and connection. A protruding strip 5 is horizontally fixed at the lower inside of the cabinet body 1. A T-shaped groove 51 is formed on the surface of the protruding strip 5. A pressing slider 6 is slidably installed inside the T-shaped groove 51. An extension platform 61 is provided on the front side of the pressing slider 6, extending beyond the front surface of the protruding strip 5. Locking knobs 7 are symmetrically screwed on both sides of the surface of the pressing slider 6. The locking knobs 7 are made of high-strength stainless steel and can provide stable locking during the locking process. A certain friction force is provided to prevent the slider from loosening during use. The slider 6 is locked and fixed by two locking knobs 7 to ensure the stability of the fixing device. A fan-shaped fixing box 8 is provided on the front side of the extension platform 61. The front side of the fan-shaped fixing box 8 is open to facilitate the installation and adjustment of cables. A cable collection tube 9 is provided at the bottom of the fan-shaped fixing box 8. The cable collection tube 9 corresponds to the cable outlet tube 101 to ensure that the cables can pass through smoothly and be collected. Cable separation holes 81 are evenly opened on the curved surface of the top of the fan-shaped fixing box 8. The front side of the cable separation holes 81 is open to facilitate the passage and separation of multiple cables. The cable separation holes 81 are used to isolate the cables, and the cables pass downward through the cable collection tube 9 to avoid the cables from getting tangled and reduce the wear of the cables during long-term use.

[0027] refer to Figure 3 and Figure 4As shown, mounting plates 91 are symmetrically arranged above the front surface of the cable tray 9. The mounting plates 91 are made of aluminum alloy, which has excellent strength and corrosion resistance. A rotating shaft 10 is rotatably mounted between the two mounting plates 91. A fan-shaped sealing plate 11 is provided on the top of the rotating shaft 10. The fan-shaped sealing plate 11 is placed on the front side of the fan-shaped fixing box 8 and the two are compatible. The fan-shaped sealing plate 11 seals the open front end of multiple cable separation holes 81 to prevent the cable from falling out of the cable separation hole 81 limit. At the same time, it can effectively improve the sealing performance of the device, protect the cable from external pollution such as dust and moisture, and extend the service life of the cable.

[0028] refer to Figure 4 and Figure 5 As shown, a swing plate 12 is provided at the bottom of the rotating shaft 10. A hollow groove 13 is opened on the surface of the swing plate 12 to facilitate the rotation and sealing function of the fan-shaped sealing plate 11 through the swing plate 12. A fixing bolt 14 is welded to the front surface of the hub 9. The fixing bolt 14 passes through the hollow groove 13. The fixing bolt 14 is made of corrosion-resistant steel to ensure the stability and durability of the device during long-term use.

[0029] refer to Figure 3 and Figure 4 As shown, a spring 16 is fitted on the surface of the fixing bolt 14. The spring 16 is placed between the swing plate 12 and the cable drum 9, and can provide a certain restoring force, so that the swing plate 12 can return to its original position without applying external force, maintain the sealing state, ensure the connection and sealing of the sector sealing plate 11 and the cable separation hole 81, and avoid loss of sealing during use. When installing the cable, the sector sealing plate 11 can be quickly lifted by pressing the swing plate 12, and automatic sealing can be achieved after installation. An adjusting nut 15 is screwed on the surface of the spring 16. The adjusting nut 15 is placed in front of the swing plate 12, and the tightness of the adjusting nut 15 can be adjusted by rotating it to adjust the elasticity of the spring 16, thereby achieving appropriate pressure adjustment of the sealing plate 12 and ensuring that the sealing effect reaches the best state.

[0030] refer to Figure 3 and Figure 6 As shown, a rotating screw 17 is rotatably inserted through the lower front surface of the cable tray 9. The rotating screw 17 is made of high-strength alloy steel, possessing excellent wear resistance and high-precision rotation performance. A pressing plate 18 is screwed onto one end of the rotating screw 17. The pressing plate 18 is placed inside the cable tray 9, and a concave surface 181 is provided on the rear side of the pressing plate 18. The concave surface 181 presses and fixes the cables inside the cable tray 9, preventing the cables from loosening or shifting due to long-term use or external forces. By rotating the rotating screw 17, the position of the pressing plate 18 can be precisely adjusted to achieve precise fixing and adjustment of the cables, ensuring cable stability and effectively preventing power system failures caused by cable loosening or shifting.

[0031] The working principle of this utility model is as follows: When in use, the extrusion slider 6 is placed inside the T-shaped groove 51 through one side opening, and then its position is adjusted and fixed by screwing on the locking knobs 7 on both sides. The fan-shaped fixing box 8 is placed outside the protrusion 5. Then, multiple cables are passed through the cable separation holes 81 respectively, and the cables are isolated through the cable separation holes 81. They are then passed down through the cable collection tube 9 for centralized processing. Due to the presence of the spring 16, the swing plate 12 always has an outward force, which causes the end of the fan-shaped sealing plate 11 to rotate backward to seal the front opening of the multiple cable separation holes 81, thereby ensuring the stability of a single cable. When installing the cable, the swing plate 12 can be pressed to make the fan-shaped sealing plate 11 rotate outward, which then makes the fan-shaped sealing plate 11 open with the fan-shaped fixing box 8, which facilitates the installation of the cable. Rotating the rotating screw 17 can control the position of the extrusion plate 18, so that the cable can be further extruded and fixed through the extrusion plate 18.

[0032] Multiple cable separation holes 81 divide the cables, so that the switch cabinet can quickly distinguish the cables during inspection and maintenance. The fan-shaped structure can also be used to concentrate multiple cables, reduce the bending angle of the cables when they are fixed, and effectively protect the cables.

[0033] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
