[0023] Embodiment 1
[0024] like Figure 1 , Figure 2 As shown, a cable includes, from the inside to the outside, a cable core 1, an inner tensile layer 2, an outer tensile layer 3, a bending resistance layer 4, a protective layer 5, and an anti-bending mechanism 6. The cable core 1 is composed of a cable conductor and an insulating shielding layer. The inner tensile layer 2 is made of polyethylene polypropylene, and the outer tensile layer 3 is made of glass fiber mesh cloth. Both have the advantages of high tensile strength, strong impermeability, and good flexibility. The bending resistance layer 4 is arranged between the outer tensile layer 3 and the protective layer 5. The bending resistance layer 4 is made of rubber material, so that it can play a buffering role when the cable is bent, enhance the bending ability and is not easy to break. The protective layer 5 is made of polyvinyl chloride, which has the characteristics of high tensile strength, large elasticity and elongation, good adhesion, water resistance and weather resistance, etc. It can be used cold and has a long service life. The anti-bending mechanism 6 has four groups, which are compounded on the outer wall circumferential surface of the protective layer 5 at 90 degrees clockwise; the anti-bending mechanism 6 includes an anti-bending protrusion 61 and an arch plate 62, wherein the anti-bending protrusion 61 is made of nitrile silicone rubber and is in a rectangular strip shape; the arch plate 62 is arched and made of nylon. The arch structure can ensure the anti-bending ability of the cable. At the same time, the overall arrangement of the arch plate 62 is simpler than the existing structure of arranging round rods and round tubes in the anti-bending protrusion 61. The anti-bending mechanism 6 first shares part of the external pressure, and then the rubber anti-bending layer 4 further buffers the pressure, so that the anti-bending ability of the cable is stronger.
[0025] In this embodiment, columnar cavities 41 are provided in the anti-bending layer 4, and the cavities 41 are arranged equidistantly in the circumferential direction; in this way, the compressive strength of the cable core 1 or the entire cable can be increased.
[0026] In this embodiment, the outer wall of the protective layer 5 is composited with carbon fibers 7, which have the advantages of high axial strength and modulus, low density, high specific performance, no creep, good fatigue resistance and corrosion resistance.
[0027] In practical applications, the cable core 1, the inner tensile layer 2, the outer tensile layer 3, the protective layer 5, the anti-bending protrusions 61, and the carbon fiber 7 are all existing technologies and will not be described in detail.
[0028] The beneficial effect of this embodiment is that the bending strength of the cable can be guaranteed by the arrangement of the bending resistance mechanism 6 and the bending resistance layer 4. The arrangement of the arched plate 62 ensures the bending resistance of the cable, and at the same time, it is simpler than the existing structure of arranging round rods and round tubes in the bending resistance protrusion 61, and simplifies the structural arrangement. The arrangement of the inner tensile layer 2, the outer tensile layer 3, the protective layer 5, etc. ensures the tensile strength of the cable, so that the overall performance of the cable is better.
[0029] Embodiment 2
[0030] The difference between this embodiment and the first embodiment is that the cable further includes a fire retardant layer 8 , and the fire retardant layer 8 is arranged between the anti-bending layer 4 and the protective layer 5 .
[0031] In this embodiment, the fire retardant layer 8 is made of ceramic silicone rubber.
[0032] The beneficial effect of this embodiment is that by setting the ceramic silicone rubber layer, the fire retardant effect of the cable is improved. By setting the anti-bending mechanism 6 and the anti-bending layer 4, the bending strength of the cable can be guaranteed. By setting the arch plate 62, its arch structure not only ensures the bending resistance of the cable, but also is simpler than the existing structure of setting round rods and round tubes in the anti-bending protrusion 61, simplifying the structural setting. By setting the inner tensile layer 2, the outer tensile layer 3, the protective layer 5, etc., the tensile strength of the cable is guaranteed, so that the overall performance of the cable is better.
[0033] Advantages of the utility model:
[0034] 1. Good bending resistance, not easy to break or damage, simple structure, safe and reliable, long service life;
[0035] 2. Excellent mechanical properties such as tensile strength, tear resistance and impact resistance;
[0036] 3. Materials are easily available and cost-effective;
[0037] 4. Good fire retardant effect.
