[0025] 1. A bending protection component is provided. When bending, the outer 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. Thus, when bending, it can ensure that the internal insulation structure of the cable will not be pulled and torn, guarantee the integrity of the insulation effect, and still provide good support performance and insulation performance for the inside of the cable after internal expansion. And when bending and expanding, since the sliding plate continuously slides to fill the gap caused by bending and expanding, it prevents the internal structure gap caused by deformation, maintains the overall strength of the cable after bending, and ensures that the cable still has strong anti-impact ability when suffering some external force impacts, preventing the internal power transmission core and data optical fiber from being impacted;

[0026] In the retraction area, the sliding plate continuously retracts, forcing the material of the insulating layer to change from internal extrusion to transverse extrusion, reducing the arc of internal extrusion, reducing the probability of extrusion deformation of the power transmission core and data optical fiber, improving the integrity of the power transmission core and data optical fiber, preventing the local power transmission temperature from rising and the resistance from increasing caused by the power transmission core being extruded at one point, and preventing unstable data transmission caused by the data optical fiber being extruded, enabling the staff to quickly and effectively understand the states of both ends of the cable, the power supply equipment and the power consumption equipment, and perform intelligent power consumption scheduling, thereby further improving the stability of cable power supply.

[0027] 2. An information component is provided, and a soft magnetic plate of a corresponding color is adsorbed and installed inside an adsorption groove on one side of the installation block, thereby fixing the soft magnetic plate. Subsequently, when the cable needs to be maintained after a period of use, the operator can first quickly determine the position of the cable according to the large soft magnetic plate, and then scan the installation block with a scanning mobile phone to identify the NFC chip and the antenna, so that all information of the cable can be read. When maintaining the cable, all materials and equipment required for cable maintenance can be quickly prepared according to the specific information, further improving the cable maintenance efficiency and ensuring the stability of cable power transmission.

[0028] In summary, when the cable deforms, it will push the limit rubber strip at the corresponding position. At this time, the limit rubber strip will undergo a certain degree of reduction deformation, thereby reducing the displacement of the inner rubber sleeve, ensuring that there is always sufficient heat dissipation space on the outside of the inner rubber sleeve, reducing the internal resistance of the cable and improving the power transmission efficiency. And by identifying the NFC chip and the antenna, various effective information of the cable can be quickly determined, so that the cable can be quickly maintained and inspected, further ensuring the stability of cable power transmission, strengthening the cable from the inside to the outside, and further improving the stability of cable power transmission.

[0053] The working principle and usage process of the present invention: First, when an operator installs a cable, the laying route of the cable should be planned well to minimize the large-curvature bending of the cable. When bending is required, two bending points will be formed in the bending area of the cable. One is the outer expansion area of the large-curvature bending on the outside, and the other is the inner contraction area of the extrusion and contraction on the inside;

[0054] Before bending, the insulating rubber 1 in the outer expansion area will stretch to both sides, thus pulling the part closely connected to the inside 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 both move in the same direction as the fixing ring 201 moves. When the front rubber plate 206 and the rear rubber plate 210 are pulled, the sliding plate 215 will slide backward in the clamping groove 211 under the action of the two support springs 219 and thus continuously be clamped inside the clamping groove 211. And due to the existence of the positioning rod 216 and the positioning groove 217, the sliding plate 215 will only slide in one direction, thus ensuring that the sliding plate 215 will always fill the clamping groove 211;

[0055] And after the fixed 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 inside 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 perform an angular offset, and the rear rubber plate 210 will also rotate outside 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 fixation, the stretching of all materials inside the cable will stop. At this time, the deformation of the outer expansion area is basically completed. When bending, the outer expansion area 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 as to ensure that the insulating structure inside the cable will not be pulled and torn during bending, ensuring the integrity of the insulating effect. After the internal outer expansion, it can still provide good support performance and insulating performance for the inside of the cable. And when bending and expanding, since the sliding plate 215 continuously slides to fill the gap caused by bending and expanding, it prevents the internal structure gap caused by deformation, maintains the overall strength of the cable after bending, ensures that the cable still has strong anti-impact ability when suffering some external force impacts, and prevents the internal power transmission core 223 and data optical fiber 224 from being impacted;

[0056] Next, during bending, the inner contraction area will also undergo large deformation. Since the insulating rubber 1 on the outer layer of the cable is generally made of a hard material and has poor local deformation ability, most of the insulating materials in the inner contraction area can only deform inward and squeeze the power transmission core 223 and data optical fiber 224. At this time, during bending, the fixed ring 201 in the inner contraction area will move towards the positioning ring 212. When moving, it will simultaneously push the front rubber plate 206 and the rear rubber plate 210 to move. Subsequently, when the rear rubber plate 210 is pushed, the position of the clamping groove 211 will also move simultaneously. Then, when the clamping 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 into the inner side of the thread groove 218, so that the sliding plate 215 continuously retracts into the inner side of the extended sliding groove 214, forcing the material of the insulating layer to change from inward extrusion to lateral extrusion, reducing the arc of inward extrusion, reducing the probability of extrusion deformation of the power transmission core 223 and data optical fiber 224, improving the integrity of the power transmission core 223 and data optical fiber 224, preventing the local power transmission temperature from rising and the resistance from increasing caused by the power transmission core 223 being squeezed at a point, and preventing the data transmission from being unstable when the data optical fiber 224 is squeezed, enabling the staff to quickly and effectively understand the states of both ends of the cable, the power supply equipment and the power consumption equipment, and perform intelligent power consumption scheduling, thereby further improving the stability of cable power supply;

[0057] And when the cable deforms, no matter how it is bent from any angle, it will push the limit rubber strip 220 at the corresponding position. At this time, the limit rubber strip 220 will undergo a certain degree of reduction deformation, thereby reducing the displacement of the inner rubber sleeve 222, ensuring that there is always sufficient heat dissipation space on the outside of the inner rubber sleeve 222, reducing the internal resistance of the cable and improving the power transmission efficiency;

[0058] Finally, after the cable is installed, the different functions of different positions of the cable can be classified. The installation connecting plate 304 can be wound around the outside of the cable, so that the upper fixing buckle 305 and the lower fixing buckle 306 are adsorbed to each other by the fixing magnet 308 embedded in the inner side of the groove 307, and the upper fixing buckle 305 and the lower fixing buckle 306 are adsorbed and fixed. Then, according to the different functions of the cable, the soft magnetic plate 303 of the corresponding color is adsorbed and installed inside the adsorption groove 302 on one side of the installation block 301, so as to fix the soft magnetic plate 303. Subsequently, when the cable needs to be maintained after being used for a period of time, the operator can first quickly determine the position of the cable according to the large soft magnetic plate 303, and then scan the installation block 301 with a scanning mobile phone 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 the materials and equipment required for maintaining the cable can be quickly prepared according to the specific information, further improving the cable maintenance efficiency and ensuring the stability of the cable power transmission.

[0059] Finally, it should be noted that the above are only preferred examples of the present invention and are not used to limit the present invention. Although the present invention 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 perform equivalent replacements for some of the technical features.
