[0014] Compared with the prior art, the present utility model provides a cable structure with high temperature resistance, flexibility and anti-interference, and has the following beneficial effects:

[0015] 1. A cable structure with high temperature resistance, flexibility and anti-interference. By setting a cable core, an insulating layer, an anti-interference layer, a wrapping layer, a flexible protection layer and an outer protection layer, the cable core is wrapped with an insulating layer, and there is an anti-interference layer outside the insulating layer, making the cable have excellent low temperature resistance, chemical corrosion resistance and insulation performance, and having good electrical conductivity and shielding effect, capable of providing stronger anti-interference force than a metal braided layer. The wrapping layer is wrapped with a flexible protection layer, and an outer protection layer is arranged outside the flexible protection layer, making the cable have good anti-bending and anti-stretching capabilities, and enabling the cable to maintain its physical properties even in long-term high temperature or low temperature environments.

[0016] 2. A cable structure with high temperature resistance, flexibility and anti-interference. By setting an inner cavity, a flexible protection layer, reinforcing ribs, springs and isolation strips, when an external force acts on the cable, the outside of the flexible protection layer can quickly disperse the pressure received and transmit the force to the isolation strips in the inner cavity, so that each small space can independently bear and disperse the pressure. At the same time, the reinforcing ribs also play a role. They evenly transmit the external force to the entire flexible protection layer through their own elasticity and strength to ensure that the shape of the inner cavity does not change significantly. When the external force decreases or disappears, the external springs first return to their original state, providing sufficient elastic restoring force to prevent the surface of the cable from being worn, thereby maintaining good electrical performance.

[0023] Embodiment 1

[0024] As Figure 1 - Figure 3 shown, the present utility model provides a technical solution: a cable structure with high temperature resistance, flexibility and anti-interference, including a cable core 1. An insulating layer 2 is fixedly connected to the outside of the cable core 1. The insulating layer 2 is made of polyethylene. The polyethylene inside the insulating layer 2 needs to be evenly coated on the outer layer of the conductor, and the coated polyethylene needs to undergo an appropriate curing process. An anti-interference layer 3 is fixedly connected to the outside of the insulating layer 2. The anti-interference layer 3 is made of copper tape. The copper tape inside the anti-interference layer 3 forms a wrapped structure through braiding. A wrapping layer 5 is fixedly connected to the outside of the anti-interference layer 3. The wrapping layer 5 is made of fluoroplastic. The fluoroplastic film tape inside the wrapping layer 5 is evenly wrapped around the wire core by a wrapping machine. A flexible protection layer 6 is fixedly connected to the outside of the wrapping layer 5. The flexible protection layer 6 is made of polyurethane. The polyurethane inside the flexible protection layer 6 is in a multi-layered, mutually staggered and overlapping state. A buffer component for anti-tensile force is arranged inside the flexible protection layer 6. An outer protection layer 8 is fixedly connected to the outside of the flexible protection layer 6. The outer protection layer 8 is made of silicone rubber. The silicone rubber inside the outer protection layer 8 needs to be evenly coated on the outermost layer of the cable.

[0025] In this embodiment, first, the cable core 1 is wrapped with an insulating layer 2, and an anti-interference layer 3 is fixedly connected to the outside of the insulating layer 2, making the cable have excellent low-temperature resistance, chemical corrosion resistance and insulation performance, and having good electrical conductivity and shielding effect, and being able to provide stronger anti-interference ability than a metal braided layer. The wrapping layer 5 is wrapped with a flexible protection layer 6, and an outer protection layer 8 is arranged outside the flexible protection layer 6. The outer protection layer 8 is made of silicone rubber. The silicone rubber needs to be evenly coated on the outermost layer of the cable and has a certain thickness to protect the internal structure from external physical and environmental influences. The coating thickness should be determined according to the use environment and performance requirements of the cable to ensure sufficient mechanical protection.

[0026] Embodiment 2

[0027] As Figure 1 - Figure 3As shown in the figure, the buffer assembly includes a flexible protective layer 6. An inner cavity 4 is formed inside the flexible protective layer 6. A plurality of partition strips 10 are fixedly connected inside the inner cavity 4. A plurality of reinforcing ribs 7 are fixedly connected inside the flexible protective layer 6. A spring 9 is sleeved outside the flexible protective layer 6.

[0028] In this embodiment, when an external force acts on the cable, the outside of the flexible protective layer 6 can quickly disperse the pressure received and transmit the force to the partition strips 10 in the inner cavity 4, so that each small space can independently bear and disperse the pressure. At the same time, the reinforcing ribs 7 also play a role. They evenly transmit the external force to the entire flexible protective layer 6 through their own elasticity and strength, ensuring that the shape of the inner cavity 4 does not change significantly. When the external force decreases or disappears, the external spring 9 first returns to its original state, so that each layer can effectively share and absorb the pressure, greatly improving the overall impact resistance.

[0029] The working principle of this embodiment: The outside of the cable core 1 is wrapped with an insulating layer 2, and there is an anti-interference layer 3 outside the insulating layer 2, making the cable have excellent low-temperature resistance, chemical corrosion resistance and insulation performance, and having good electrical conductivity and shielding effect, and being able to provide stronger anti-interference ability than a metal braid layer. The outside of the wrapping layer 5 is wrapped with a flexible protective layer 6, and an outer protective layer 8 is arranged outside the flexible protective layer 6, making the cable have good bending and tensile resistance, and enabling the cable to maintain its physical properties in a long-term high-temperature or low-temperature environment; when an external force acts on the cable, the outside of the flexible protective layer 6 can quickly disperse the pressure received and transmit the force to the partition strips 10 in the inner cavity 4, so that each small space can independently bear and disperse the pressure. At the same time, the reinforcing ribs 7 also play a role. They evenly transmit the external force to the entire flexible protective layer 6 through their own elasticity and strength, ensuring that the shape of the inner cavity 4 does not change significantly. When the external force decreases or disappears, the external spring 9 first returns to its original state, providing sufficient elastic restoring force, gradually decreasing the pressure layer by layer from the inside to the outside, enabling each part to effectively share the pressure, greatly reducing the risk of damage to the core components, and improving the overall impact resistance.

[0030] The above is only a preferred embodiment of the present invention, and does not limit the present invention in other forms.
