[0018] Please refer to Figures 1-6 The present embodiment provides a technical solution: an anti-aging cable and a preparation method thereof, comprising winding wires 1, a fastening mechanism 3 and an anti-bending mechanism 5. The main line cable rubber sleeve 1 is a nylon cable rubber sleeve, and the three main line cable rubber sleeves 1 are wound together. The inner part of each of the three main line cable rubber sleeves 1 is provided with uniformly distributed electric wires, and the electric wires in the same three main line cable rubber sleeve 1 are combined into a single wire helix. The fastening mechanism 3 comprises a buckle ring 31 and an arc contact section 32. The buckle ring 31 is uniformly and movably sleeved on the outer surface of the three main line cable rubber sleeves 1, and the inner arc surface of the buckle ring 31 is provided with uniformly distributed arc contact sections 32. The inner arc surface of the arc contact section 32 is in contact with the outer arc surface of the corresponding main line cable rubber sleeve 1 in the longitudinal position. The fastening mechanism 3 further comprises a circular clamping groove 33 and a circular clamping bead 34. The circular clamping groove 33 is respectively provided on the front side wall of the buckle ring 31, and the rear side wall of the buckle ring 31 is respectively fixedly connected with the circular clamping bead 34. The outer surface of the three main line cable rubber sleeves 1 wound together is wound with an outer wrapping 2, which is located between the outer arc surface of the main line cable rubber sleeve 1 and the interlayer of the buckle ring 31. The fastening mechanism 3 is further provided with a filler 4, which is uniformly adhered to the outer arc surface of the outer wrapping 2 by a glue layer (the glue layer can be a modified silicone cable adhesive). The filler 4 is distributed at intervals with the fastening mechanism 3. The outer wrapping 2 is a polyimide film, and the number of winding layers is two. The material of the filler 4 is a polypropylene patch, and the material of the buckle ring 31 is a modified ABS plastic. The anti-bending mechanism 5 is arranged outside the main cable rubber sleeve 1, and the outer part of the anti-bending mechanism 5 is provided with an anti-aging outer sheath 6. The anti-bending mechanism 5 comprises an inner metal interwoven net 51, a rubber filling sleeve 52 and an outer metal interwoven net 53. The rubber filling sleeve 52 is fixedly sleeved on the outer arc surface of the filler 4. The inner arc surface of the rubber filling sleeve 52 is fixedly connected with the inner metal interwoven net 51. The outer arc surface of the rubber filling sleeve 52 is fixedly connected with the outer metal interwoven net 53. The inner metal interwoven net 51 and the outer metal interwoven net 53 are respectively embedded in the inner part of the rubber filling sleeve 52. The inner surface of the inner metal interwoven net 51 is located on the same arc surface as the inner arc surface of the rubber filling sleeve 52. The outer surface of the outer metal interwoven net 53 is located on the same arc surface as the outer arc surface of the rubber filling sleeve 52. The size of the inner metal interwoven net 51 is smaller than the size of the outer metal interwoven net 53. The inner metal interwoven net 51 and the outer metal interwoven net 53 are both woven by steel wires. The steel wires are interwoven in a diamond shape. The outer arc surface of the rubber filling sleeve 52 is fixedly sleeved with the anti-aging outer sheath 6. The anti-aging outer sheath 6 is an XLPE protective sheath. When the anti-aging cable is connected with external electrical equipment and electrically connected with the external electrical equipment, the electric wires in the main cable rubber sleeve 1 are connected with the external electrical equipment. Then the anti-aging cable can be laid. The steel wires in the inner metal interwoven net 51 and the steel wires in the outer metal interwoven net 53 support the rubber filling sleeve 52. The steel wires are composed of multiple metal wires. When the steel wires are bent, they have a certain maximum bending angle, which is transmitted to the rubber filling sleeve 52 and the cable is supported by the rubber filling sleeve 52, so that the cable has a certain bending resistance. When the anti-aging cable is subjected to a bending force, the bending resistance of the cable supports the entire cable and limits the maximum bending angle. During the laying of the cable, if the three main cable rubber sleeves 1 are loose, the clasp 31 will tighten the three main cable rubber sleeves 1. The outer arc surface of the clasp 31 is supported by the inner metal interwoven net 51, and the side surface of the clasp 31 is supported by the filler 4, thereby preventing the three main cable rubber sleeves 1 from being loose.The side of the buckle 31 will be supported by the filler 4, fastening the three main cable rubber sleeves 1 to prevent them from loosening; An aging-resistant cable comprises the following steps: S1: Manufacturing process of main line cable rubber sleeve 1: The main line cable rubber sleeves 1 can be wound together by an external winding machine to form a thicker main conductor. The way this cable is electrically connected to external devices is to form a circuit path through the main conductor; S2: Winding process of outer wrap 2: outer wrap 2 can be wound on the outer surface of the main conductor by an external wrapping machine. The outer wrap 2 is spirally wound. During the spiral process, the right side of the outer arc surface of the outer wrap 2 will be wrapped by the left side of the inner arc surface of the next spiral layer, forming two winding layers to tighten the main conductor. S3: Installation of the fastening mechanism 3: Take the main conductor that is tightly wound by the outer wrapper 2, and stick the filler 4 on its surface. After the filler 4 is bonded, buckle a buckle 31 on the left side of the filler 4, so that the inner arc surface of the arc-shaped contact section 32 on the buckle 31 fits the bulged part of the main conductor, and then snap the circular clamping bead 34 into the inner part of the circular clamping groove 33. Then repeat the above steps to fix the fastening mechanism 3 and the filler 4 on the outer arc surface of each section of the main conductor respectively, and the fastening mechanism 3 and the filler 4 are spaced apart. S4: Production of the anti-bending part: The steel wires of the inner metal mesh 51 are first braided by an external weaving device to form the inner metal mesh 51 on the outer arc surface of the outer metal mesh 53. The rubber is squeezed around the inner metal mesh 51 by an external extruder to form a rubber filling sleeve 52. When the rubber filling sleeve 52 is in a semi-molten state, the steel wires are further wound by an external weaving device to form the outer metal mesh 53. At this time, the rubber filling sleeve 52 can be cooled.

[0019] The working principle of the anti-aging cable and the preparation method thereof is as follows: when the anti-aging cable is connected with external electrical equipment and is electrically connected with the external electrical equipment, the electric wire in the main cable rubber sleeve 1 is connected with the external electrical equipment, and then the steel wire in the inner metal interwoven net 51 and the steel wire of the outer metal interwoven net 53 support the rubber filling sleeve 52, the steel wire is composed of a plurality of metal wires, and when the steel wire is bent, it has a certain bending resistance, and the bending resistance is transmitted to the rubber filling sleeve 52, and the rubber filling sleeve 52 supports the cable, so that the cable has a certain bending resistance. When the anti-aging cable is subjected to a bending force, the bending resistance of the cable itself will support the entire cable and limit the maximum bending angle. During the laying of the cable, if the three main cable rubber sleeves 1 are loose, the clasp 31 will tighten the three main cable rubber sleeves 1, the outer arc surface of the clasp 31 will be supported by the inner metal interwoven net 51, and the side surface of the clasp 31 will be supported by the filler 4, thereby tightening the three main cable rubber sleeves 1 and preventing them from loosening.
