Description

Technical Field

[0001] This utility model belongs to the field of cable fixing technology, and specifically relates to a cable fixing mechanism for control cabinets. Background Technology

[0002] Currently, control cabinets are often used in the electrical field to control equipment. Control cabinets usually contain a lot of wires. When the wires are too messy, they are easy to get tangled together, which makes it difficult to organize the cables during subsequent wiring. Therefore, it is necessary to install a fixing mechanism inside the cabinet to fix the organized cables.

[0003] Currently, Chinese utility model patent CN220023371U discloses a cable fixing device for electrical control cabinets. Although this fixing mechanism can adjust the space of the internal cable tray, it still has other problems in use. For example, it does not have a distance adjustment function, and the fixing device needs to be installed based on the cabinet wall. However, after the components inside the cabinet are assembled, they are often located in the center or outside of the cabinet. At this time, there is a distance difference between the fixing mechanism and the components. If the cable is forcibly bent and inserted, it will damage the cable. It has poor flexibility and does not have an adaptive clamping function. It is difficult to accurately control the clamping force by tightening with a screw. If it is too tight, it will damage the cable insulation layer, and if it is too loose, it will loosen. When the cable undergoes slight deformation due to temperature changes, it cannot provide appropriate compensating clamping force. Utility Model Content

[0004] The purpose of this utility model is to provide a cable fixing mechanism for a control cabinet, which has the advantages of having both long-distance and short-distance adjustment functions and self-adaptive clamping function.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a cable fixing mechanism for a control cabinet, including a mounting plate, a base provided on the front of the mounting plate, a fixing frame bolted to the top of the base, two sliders slidably placed inside the fixing frame, an adjusting plate rotatably connected between the top of the sliders and the mounting plate via a rotating shaft, a threaded rod welded to the front of the sliders, a nut threadedly connected to the surface of the threaded rod, a wire-passing groove provided on the front of the base, a fixing plate bolted to the front of the base, a limiting plate provided inside the wire-passing groove, and a fixing spring bolted between the front of the limiting plate and the fixing plate via a spring fixing piece.

[0006] The above technical solution has the function of adjusting the distance, which can be adjusted appropriately according to the installation position of the component to avoid damage to the cable due to excessive bending. It has good flexibility and also has an adaptive clamping function. It is simple and convenient to operate and can automatically compensate for the clamping force when the cable is deformed, reducing cable wear and making it highly practical.

[0007] The present invention is further configured such that a spring washer is slidably sleeved on the surface of the threaded rod.

[0008] The above technical solution improves the fixing effect of the nut after tightening by setting spring washers, thus achieving the effects of shock absorption and preventing loosening.

[0009] The present invention is further configured such that two mounting holes are provided on the front side of the mounting plate.

[0010] The above technical solution allows for easy fixing of the mounting plate with screws by the installation holes, reducing the hassle of temporary drilling.

[0011] The present invention is further configured such that a fixing rod is welded to the front side of the limiting plate, a through hole is opened on the front side of the fixing plate for use with the limiting plate, and the other end of the fixing rod extends to the outside of the through hole and is bolted with a pull plate.

[0012] The above technical solution allows for easy pulling of the limiting plate forward by the use of a fixing rod and a pull plate.

[0013] The present invention is further provided that a protective pad is adhered to the inside of the threading groove, and the protective pad is made of rubber material.

[0014] The above technical solution protects the cable by providing a protective pad, preventing the limiting plate from scratching the cable sheath when clamping.

[0015] The present invention is further configured such that the fixed frame, slider, adjusting plate, threaded rod and nut are all made of stainless steel.

[0016] The above technical solution features a fixed frame, slider, adjusting plate, threaded rod, and nut with high strength, low density, and excellent corrosion resistance.

[0017] The present invention is further configured such that the fixing spring is made of carbon spring steel.

[0018] Using the above technical solution, the fixed spring has the characteristics of excellent mechanical properties, good anti-elasticity, low temperature resistance and corrosion resistance.

[0019] In summary, this utility model has the following beneficial effects: 1. First, fix the mounting plate to the inner wall of the control cabinet with screws. After the mounting plate is fixed, grab the base and pull it forward. When the base is pulled forward, the front end of the adjustment plate will drive the slider to move outward within the fixed frame. When the slider moves outward, it will drive the threaded rod and nut to move together. When the base is pulled forward until the internal cable groove is aligned with the component, tighten the nut. It has the function of adjusting the distance, and can be adjusted appropriately according to the installation position of the component to avoid damage to the cable due to excessive bending. It has good flexibility. 2. When connecting via cable, use one hand to grasp the pull plate and move the fixing rod outward. As the fixing rod moves outward, it will cause the limiting plate to move forward. When the limiting plate moves forward, it will compress the fixing spring, causing it to contract and deform. After the pull plate is pulled out to the bottom, use the other hand to pass the cable through the cable pass-through groove from below and connect it to the component. Then, straighten the cable and release the pull plate. It has an adaptive clamping function, is simple and convenient to operate, and can automatically compensate for the clamping force when the cable is deformed, reducing cable wear and making it highly practical.
