[0020] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described, obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor are within the protection scope of the present application.

[0021] Embodiment 1: please refer to Figures 1-4 , high elastic and shaped flexible wire cable, including wire core 1, the outer surface of wire core 1 is provided with inner protective layer 2, inner protective layer 2 is wrapped with insulating layer 3, insulating layer 3 is wrapped with filling layer 4, the outer surface of filling layer 4 is provided with waterproof layer 5, the outer surface of waterproof layer 5 is provided with buffer layer 6, the outer surface of buffer layer 6 is provided with fireproof layer 7, the outer surface of fireproof layer 7 is provided with outer protective layer 8;

[0022] Inner protective layer 2 is made of PVC material, and inner protective layer 2 is wrapped on the outer side of wire core 1, and the outer surface of inner protective layer 2 is circular.

[0023] Filling layer 4 is arranged between insulating layer 3 and waterproof layer 5, filling layer 4, insulating layer 3 and waterproof layer 5 are all arranged in the form of circular ring and wrapped on the outer side of inner protective layer 2.

[0024] Specifically, wire core 1 is made of copper, has high conductivity, good thermal conductivity and good mechanical properties, and is responsible for transmitting electric energy or electric signal. Its high conductivity can reduce the loss of electric energy in the transmission process, and ensure efficient power transmission or signal transmission. Good thermal conductivity helps to dissipate heat in time during work, preventing the wire core from overheating and affecting performance. Suitable mechanical properties ensure that wire core 1 can withstand certain external forces such as stretching and bending during manufacturing, installation and use, without easily breaking, inner protective layer 2 is tightly wrapped on the outer side of wire core 1 and is made of PVC (polyvinyl chloride), has certain insulation performance, can assist insulating layer 3, enhance the insulation protection of wire core 1, prevent the occurrence of electric leakage, create a relatively stable internal environment for wire core 1, and its outer surface is circular, which helps to maintain the shape of wire core 1 and provides a regular basic shape for the subsequent wrapping of insulating layer 3, so that the whole cable structure is more regular.

[0025] The insulation layer 3 is made of XLPE (cross-linked polyethylene) which has excellent electrical insulation performance, aging resistance and mechanical properties, and can prevent current leakage into the surrounding structure. The filling layer 4 is made of polyester fiber, which is filled in the gap between the insulation layer 3 and the waterproof layer 5, so as to keep the cable in a circular cross-sectional shape, and help maintain the structural stability of the cable. When the cable is squeezed or bent, the filling layer 4 can prevent deformation and displacement of the internal structure. The waterproof layer 5 is made of PE (polyethylene), which has good waterproof performance, preventing moisture from entering the cable, thereby avoiding problems such as reduced insulation performance and material corrosion, prolonging the service life of the cable and ensuring the performance stability of the cable.

[0026] Example 2: To improve the tensile performance of the cable and adapt to different working conditions for bending, please refer to Figures 1-4 On the basis of example 1, the buffer layer 6 is in a honeycomb structure and has a cylindrical shape. The buffer layer 6 is made of TPE material.

[0027] The fireproof layer 7 is a fireproof coating layer, and the thickness of the fireproof layer 7 is 0.5-1mm.

[0028] The outer protective layer 8 is a PVC layer, and a net-like braid 81 is arranged on the inner side of the outer protective layer 8. The net-like braid 81 on the inner side of the outer protective layer 8 is made of high-strength fiber, and the net-like braid 81 is arranged between the outer protective layer 8 and the fireproof layer 7.

[0029] Specifically, the cylindrical honeycomb structure of the buffer layer 6 and the TPE material give the cable good flexibility. The honeycomb structure can naturally adapt to the bending shape when the cable is bent, because each honeycomb unit can be pressed and deformed. The high elasticity of the TPE material allows it to deform elastically during bending, rather than resisting bending like rigid materials, reducing stress concentration when the cable is bent, so that the cable can easily adapt to bending.

[0030] The net-like braid 81 made of high-strength fiber has a net-like structure formed by interlacing fibers, which has a certain flexibility and does not hinder the bending of the cable. When the cable is subjected to tension, the tension will be transmitted to the net-like braid 81 through the outer protective layer 8. The net-like structure can evenly distribute the tension to each fiber, avoiding stress concentration in a certain point or area, so that the cable can withstand greater tension without easily breaking. The net-like braid 81 is closely combined with the outer protective layer 8, increasing the strength and toughness of the outer protective layer 8. Under the action of tension, the outer protective layer 8 itself is not easy to tear, break or damage, and can better maintain its shape and structural integrity.

[0031] The fireproof layer 7 is a fireproof paint. The cable fireproof paint is composed of tertiary propylene emulsion water-based material and various fireproofing agents, plasticizers and the like. When the paint coating is on fire, it can generate a uniform and dense sponge-like foam heat insulation layer, effectively inhibiting and blocking the spread and spread of fire, thereby protecting the electric wire and cable. The outer protective layer 8 is made of PVC and can resist the invasion of various physical, chemical and environmental factors from the outside, ensuring the long-term stable operation of the cable.

[0032] Working principle: In the device, the wire core 1 made of copper serves as the core part and undertakes the task of transmitting electric energy or electric signal. The inner protective layer 2 made of PVC tightly wraps the wire core 1, and the auxiliary insulating layer 3 with certain insulation property strengthens the insulation protection of the wire core 1 to prevent electric leakage. The circular outer surface maintains the shape of the wire core 1 and provides a regular basic shape for the insulating layer 3. The insulating layer 3 made of XLPE has excellent electrical insulation performance and prevents current leakage to the surrounding structure. The filler layer 4 made of polyester fiber material fills the gap between the insulating layer 3 and the waterproof layer 5, ensuring that the cross section of the cable is circular, preventing internal structure deformation and displacement when the cable is squeezed or bent. The waterproof layer 5 made of PE prevents water from entering the cable, avoids the decrease of insulation performance and material corrosion, prolongs the service life of the cable and ensures stable performance.

[0033] The buffer layer 6 made of TPE has a cylindrical honeycomb structure and good flexibility. The honeycomb cells deform and extrude each other to adapt to the bending shape when bending. The TPE elastic deformation reduces the bending stress concentration, which is beneficial to the bending of the cable. The fireproof layer 7 with a thickness of 0.5-1 mm (composed of tertiary propylene emulsion water-based material and fireproofing agents, plasticizers and the like) generates a sponge-like foam heat insulation layer when on fire, inhibits and blocks the spread of fire, and protects the cable. The outer protective layer 8 made of PVC resists the invasion of physical, chemical and environmental factors from the outside. The inner net-like braid 81 made of high-strength fibers does not hinder bending due to its flexibility when the cable is bent. When subjected to tension, the net-like structure of the fiber interweaving uniformly disperses the tension to each fiber, avoiding stress concentration, enhancing the strength and toughness of the outer protective layer 8, making it not easy to tear and damage, maintaining the shape and structure integrity, improving the tensile performance of the cable, and ensuring the long-term stable operation of the cable.
