AI Technical Summary
当电缆松动量达到一定阈值时,电缆与接口的配合间隙增大,接触面压力降低,最终导致电缆接口处出现电接触不良问题,严重时甚至引发局部过热、电弧放电等安全隐患,影响整个电路系统的稳定运行
[0018]This invention utilizes a combination of an adjustment mechanism and an anti-loosening mechanism. The adjustment mechanism's adjusting cylinder and adjusting screw work together; rotating the adjusting cylinder drives the adjusting screw to move the pressure plate. The clamping force of the pressure plate can be flexibly adjusted according to the actual specifications of the cable, ensuring the cable is stably clamped within the junction box and preventing cable displacement due to insecure clamping. The anti-loosening mechanism's limiting toothed ring, under the action of a return spring, always engages with the rotating toothed ring fixed on the adjusting cylinder, forming an effective limiting effect. This prevents the clamping force of the pressure plate from weakening due to the rotation of the adjusting cylinder, preventing loosening between the cable and the junction box. This reduces safety hazards such as poor electrical contact at the cable interface, localized overheating, and arc discharge, ensuring the stable operation of the entire circuit system.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of cable wiring technology, specifically to a cable wiring device for power relocation. Background Technology
[0002] A cable is a conductor made of one or more insulated conductors and an outer insulating protective layer. It is a wire that transmits electricity or information from one place to another. When relocating power lines, it is often necessary to connect two separate cables together.
[0003] Chinese Patent CN221508494U discloses a cable connection device for power relocation, including two terminals corresponding to the cable. A connector is fixed to one side of each terminal, and a fixing bolt is installed between the two connectors. A connection groove is formed inside the terminal, and two pressure plates slide within the groove. A clamping plate is installed on one side of each pressure plate, and both the pressure plates and clamping plates correspond to the cable. Threaded rods are threaded onto both sides of each terminal, corresponding to the pressure plates. The terminals, connectors, and pressure plates are all made of copper. In this invention, the connector installed on one side of the terminal can be used independently as a terminal block, facilitating cable connection. The pressure plates installed in the connection groove and the clamping plates installed on one side of the pressure plates simultaneously clamp and fix the cable's insulation and copper wire, ensuring cable stability and preventing the cable from falling. The device is reusable, and the use of pressure plates to clamp the copper wire ensures it is tightly compressed.
[0004] However, the above technical solution has the following shortcomings:
[0005] During actual operation, cables face multiple interferences, including instantaneous fluctuations in the internal current and mechanical vibrations in the environment. These interferences cause continuous mechanical impact and vibration responses in the cable. The vibration and impact forces are further transmitted to the threaded rod components used to fix the cable, disrupting the original torque balance and causing unexpected rotational displacement. As the threaded rod rotates, its clamping force on the cable gradually weakens, leading to loosening of the cable at its fixed position. When the cable loosening reaches a certain threshold, the clearance between the cable and the interface increases, the contact surface pressure decreases, and ultimately, poor electrical contact occurs at the cable interface. In severe cases, this can even lead to safety hazards such as localized overheating and arcing, affecting the stable operation of the entire circuit system. Utility Model Content
