The inner sheath layer 18 is used for accommodating a plurality of wire cores 16 to protect the wire cores 16, and meanwhile, the center support bar 17, the inner sheath layer 18 and the wire cores 16 are integrated;
in this embodiment, the center support bar 17 is made of an elastic rubber material. When bending occurs, part of the wire core 16 can press the central support bar 17 inwards to realize buffering, so that the wire core 16 is prevented from being broken;
the reinforcing pipe sleeve structure is positioned at the outer side of the wire core fixing structure and is arranged coaxially with the wire core fixing structure;
specifically, the reinforcing sleeve structure includes an outermost outer jacket layer 12 and an inner shield layer 13, and a plurality of structural reinforcing units 14 distributed in the axial direction thereof are provided between the shield layer 13 and the outer jacket layer 12.
In this embodiment, the structural reinforcement unit 14 comprises at least one stranded wire rope having a diameter of 0.05mm to 0.1mm.
The structural strength is improved by the plurality of structural reinforcement units 14, and when the outer reinforcing pipe sleeve structure is bent, the structural reinforcement units 14 prevent the reinforcing pipe sleeve structure from being broken.
The mountain crest-shaped structure 11 is arranged between the reinforced pipe sleeve structure and the wire core fixing structure, and is used for providing a buffer space when the wire core fixing structure is bent.
The flexible buffer layer 15 is made of latex materials, and a plurality of inward concave mountain crest structures 11 are uniformly formed on the inner circumferential surface of the flexible buffer layer 15.
