[0030] like Figures 1 to 4As shown, a tensile composite cable comprises: a core 1; a barrier layer 2, which is arranged on the outside of the core 1 and is used to fix the relative position of the core 1; a tensile component 5, which is arranged inside the barrier layer 2 and is used to increase the tensile strength; a support layer 4, which is arranged on the outside of the barrier layer 2 and is used to maintain the shape of the core 1; a protective layer 3, which is arranged on the outside of the support layer 4 and is used to protect the core 1. Specifically, during the use of the cable, the core 1 is protected by the barrier layer 2, and then the shape of the barrier layer 2 is maintained by the support layer 4 to avoid mutual friction between the cores 1 during use, thereby ensuring stability during use. At the same time, the support layer 4 is protected under the protection of the protective layer 3 to avoid damage to the support layer 4 caused by wear. Finally, the tensile resistance during use is increased by the tensile component 5 to avoid breakage of the cable due to stress during use.

[0031] like Figures 1 to 4 As shown, the barrier layer 2 includes an insulating layer 201, a fireproof layer 202 and a packing layer 203. The packing layer 203, the fireproof layer 202 and the insulating layer 201 are sequentially arranged on the outside of the wire core 1. A through hole and a groove 204 are arranged inside the packing layer 203. There are multiple grooves 204, and the multiple grooves 204 are evenly distributed along the axial line of the packing layer 203. The groove 204 is connected with the through hole. Specifically, the packing layer 203 fixes the distribution position of the wire core 1 to prevent the wire core 1 from being damaged by friction with each other due to the force applied to the cable during use. At the same time, the packing layer 203 protects the wire core 1 to prevent the wire core 1 from being damaged by force, thereby ensuring stability during use. The fireproof layer 202 is a heat-insulating and flame-retardant material, which protects the wire core 1 during use. The insulating layer 201 is made of polyethylene or cross-linked polyethylene, so that the wire core 1 can be isolated from the outside world to prevent power leakage and short circuit, thereby ensuring stability during use.

[0032] like Figures 1 to 4As shown, the tensile assembly 5 includes a fixing member 501, and there are multiple fixing members 501. The fixing members 501 are adapted to the groove 204. The outer side of the fixing members 501 is provided with a rotation groove 505, and the rotation axis of the rotation groove 505 is parallel to the axis of the core 1. There are multiple rotation grooves 505, and a connecting member 504 is provided inside the rotation groove 505. The rotation groove 505 is adapted to the connecting member 504, and the connecting member 504 rotates relative to the fixing member 501. Connecting rods 502 are provided between adjacent connecting members 504. Specifically, the fixing members 501 and the connecting rods 502 are both made of metal. During the use of the cable, the multiple connecting rods 502 are connected by the fixing members 501. , so that the fixing member 501 and the connecting rod 502 form a whole, thereby increasing the tensile strength of the cable when in use; the rotating groove 505 is a spherical groove, and the diameter of the opening end of the rotating groove 505 is smaller than the maximum diameter of the rotating groove 505, so that the rotating groove 505 limits the connecting member 504; since the connecting member 504 rotates relative to the fixing member 501 inside the rotating groove 505, while increasing the tensile strength of the cable, it has a certain degree of flexibility, which is convenient for bending the cable during installation; when in use, the fixing member 501 is connected to the connecting rod 502 through the cooperation of the rotating groove 505 and the connecting member 504, thereby increasing the axial tensile strength of the cable when in use.

[0033] like Figures 1 to 4 As shown, a limiting groove 503 is provided on the outer side of the fixing member 501, and the limiting groove 503 corresponds to the rotation groove 505. Specifically, the setting of the limiting groove 503 further increases the rotation angle of the connecting member 504 relative to the fixing member 501, thereby improving the overall flexibility of the cable.

[0034] like Figures 1 to 4 As shown, the support layer 4 includes a limiting layer 401, which is arranged on the outside of the insulating layer 201. A retaining ring is provided inside the limiting layer 401, and there are multiple retaining rings, which are evenly distributed along the length direction of the core 1. A support rod 402 is also provided inside the limiting layer 401, and there are multiple support rods 402, which are distributed in a ring shape around the axis of the limiting layer 401, and the support rod 402 is connected to the retaining ring. Specifically, the retaining ring is made of rubber material, so that it can be quickly reset after being deformed by force. The support rod 402 is made of nylon fiber. The retaining ring cooperates with the support rod 402 to form a pipe pile connection network. When the local retaining ring is deformed by force, the extrusion force is dispersed to the retaining ring connected to the support rod 402 through the support rod 402, thereby ensuring the radial support effect of the cable and avoiding the short circuit caused by the mutual extrusion of the cores 1 when the cable is squeezed.

[0035] like Figures 1 to 4As shown, the protective layer 3 includes a wear-resistant layer 301 and a shielding layer 302. The shielding layer 302 is arranged on the outside of the limiting layer 401, and the wear-resistant layer 301 is arranged on the outside of the shielding layer 302. Specifically, the shielding layer 302 shields the electromagnetic signals on both sides of the shielding layer 302 to prevent the wire core 1 from being affected by the electromagnetic signals during use. A metal sleeve is provided inside the wear-resistant layer 301, and the metal sleeve cooperates with the wear-resistant layer 301 to wrap the cable as a whole to prevent the cable from being damaged due to friction and puncture during use, thereby extending the overall service life of the cable.
