When bending, the expansion area continuously adapts to the bending angle of the insulating rubber through the rotation of the front rubber plate and the rear rubber plate, so that the insulation structure inside the cable will not be pulled and torn during bending, and the integrity of the insulation effect can be ensured. After the internal expansion, the cable can still provide better support and insulation performance. When bending and expanding, the sliding plate continuously slides to fill the gap caused by the bending and expansion, thereby preventing the internal structure gap caused by deformation, maintaining the overall strength of the cable after bending, and ensuring that the cable still has strong impact resistance when it is subjected to some external force impact, preventing the internal power transmission core and data optical fiber from being impacted; In the retracted area, the sliding plate is continuously retracted, forcing the material of the insulating layer to change from being squeezed inward to being squeezed laterally, reducing the arc of the inward extrusion, and reducing the probability of extrusion deformation of the power transmission core and the data optical fiber, thereby improving the integrity of the power transmission core and the data optical fiber, preventing the power transmission core from being squeezed at one point, which may cause the local power transmission temperature to rise and the resistance to increase, and preventing the data transmission from being unstable when the data optical fiber is squeezed, so that the staff can quickly and effectively understand the status of both ends of the cable, the power supply equipment and the power-consuming equipment, and conduct intelligent power scheduling, thereby further improving the stability of the cable power supply.

[0023] The working principle and use process of the present invention are as follows: First, when installing the cable, the operator should plan the laying route of the cable and try to reduce the large curvature bending of the cable. When bending is required, the bending area of ​​the cable will form two bending points, one is the outer expansion area of ​​the large curvature bending located on the outside, and the other is the inner shrinkage area of ​​the extrusion and tightening located on the inside; Before bending, the insulating rubber 1 in the outward expansion area will be stretched to both sides, thereby pulling the part closely connected to the inner side of the insulating rubber 1. When the insulating rubber 1 is pulled to both sides, the fixing ring 201 will be pulled in one direction. At this time, the front rubber plate 206 and the rear rubber plate 210 evenly move in the same direction as the fixing ring 201. When the front rubber plate 206 and the rear rubber plate 210 are pulled, the sliding plate 215 will slide toward the rear rubber plate 210 on the inner side of the clamping groove 211 under the action of the two supporting springs 219, thereby continuously clamping on the inner side of the clamping groove 211. Due to the presence of the positioning rod 216 and the positioning groove 217, the sliding plate 215 will only slide in one direction, thereby ensuring that the sliding plate 215 will always fill the clamping groove 211. And after the fixing ring 201 is pulled to a certain position, it will stop moving. At this time, the cable has been bent to a certain angle. When the insulating rubber 1 is bent to a certain angle, the connecting block 205 will rotate a certain angle on the inner side of the rotating hole 203 through the rotating shaft 204, so as to adapt to the curvature of the bending of the insulating rubber 1, drive the entire front rubber plate 206 to deviate the angle, and the rear rubber plate 210 will also rotate on the outer side of the adjusting rod 208 through the adjusting block 209 to reduce the bending resistance, and when the insulating rubber 1 is bent to a certain angle for fixing, it will stop stretching all the materials inside the cable. At this time, the deformation of the outward expansion area is basically completed, and the outward expansion during bending is The zone continuously adapts to the bending angle of the insulating rubber 1 through the rotation of the front rubber plate 206 and the rear rubber plate 210, so that the insulation structure inside the cable can be guaranteed not to be pulled and torn during bending, and the integrity of the insulation effect can be guaranteed. After the internal expansion, the cable can still provide better support performance and insulation performance. In addition, during bending and expansion, the sliding plate 215 continuously slides to fill the gap caused by the bending and expansion, thereby preventing the internal structure gap caused by deformation, maintaining the overall strength of the cable after bending, and ensuring that the cable still has strong impact resistance when subjected to some external force impact, preventing the internal power transmission core 223 and data optical fiber 224 from being impacted; Next, the shrinking zone will also undergo a large deformation during bending. Since the insulating rubber 1 on the outer layer of the cable is generally made of a harder material and has a poor local deformation ability, most of the insulating materials in the shrinking zone can only deform inward to squeeze the power transmission core 223 and the data optical fiber 224. At this time, the fixing ring 201 in the shrinking zone will move toward the positioning ring 212 during bending, and will simultaneously push the front rubber plate 206 and the rear rubber plate 210 to move simultaneously during the movement. Subsequently, when the rear rubber plate 210 is pushed, the position of the snap-in groove 211 will also move simultaneously. Then, when the snap-in groove 211 moves, it will continuously compress the position of the sliding plate 215, forcing the sliding plate 215 to compress the support spring 219 to the threaded groove 21 8, so that the sliding plate 215 is continuously retracted to the inner side of the extended sliding groove 214, forcing the material of the insulating layer to change from being squeezed inward to being squeezed horizontally, reducing the arc of the inward extrusion, reducing the probability of the transmission core 223 and the data optical fiber 224 being squeezed and deformed, improving the integrity of the transmission core 223 and the data optical fiber 224, preventing the transmission core 223 from being squeezed at one point to cause the local transmission temperature and resistance to increase, and preventing the data transmission from being unstable when the data optical fiber 224 is squeezed, so that the staff can quickly and effectively understand the status of the two ends of the cable, the power supply equipment and the power consumption equipment and intelligent power consumption scheduling, thereby further improving the stability of the cable power supply; When the cable is deformed, no matter how it bends at any angle, it will push the limiting rubber strip 220 at the corresponding position. At this time, the limiting rubber strip 220 will shrink and deform to a certain extent, thereby reducing the displacement of the inner rubber sleeve 222, so that the outer side of the inner rubber sleeve 222 will always have sufficient heat dissipation space, thereby reducing the internal resistance of the cable and improving the power transmission efficiency. Finally, after the cable is installed, the different functions of different positions of the cable can be classified, and the installation connecting plate 304 can be wrapped around the outside of the cable, so that the upper fixing buckle 305 and the lower fixing buckle 306 are embedded in the fixed magnet 308 on the inner side of the groove 307 to adsorb each other, and the upper fixing buckle 305 and the lower fixing buckle 306 are adsorbed and fixed, and then according to the different functions of the cable, the soft magnetic plate 303 of the corresponding color is adsorbed and installed on the inner side of the adsorption groove 302 on one side of the mounting block 301, so as to fix the soft magnetic plate 303. Subsequently, when the cable needs to be maintained after a period of use, the operator can first quickly determine the position of the cable based on the large soft magnetic plate 303, and then use a scanning mobile phone to scan the mounting block 301, so as to identify the NFC chip 309 and the antenna 310, and all the information of the cable can be read. When maintaining the cable, all materials and equipment required for maintaining the cable can be quickly prepared according to the specific information, so as to further improve the cable maintenance efficiency and ensure the stability of the cable power transmission.
