[0002] With the advancement of science and technology and the improvement of people's living standards, the requirements for wire performance are becoming increasingly stringent. Wires need to be able to withstand high temperatures and frequent movement for a long time. Traditional flexible wires have the following technical bottlenecks:

[0003] 1. Mechanical performance defects: Ordinary conductors are prone to metal fatigue fracture after repeated bending, and conventional filling materials are difficult to achieve both flexibility and tensile strength;

[0042] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0043] It should be noted that the terms "first," "second," and the like in the description and claims of the present invention and the accompanying drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate, such that the embodiments of the present invention described herein can be practiced in an order other than that illustrated or described herein.

[0044] like Figure 1 As shown, the present invention provides a highly flexible electric wire, comprising: a cable core, a sheath provided on the outside of the cable core, the cable core comprising: a plurality of core wires, the core wires comprising: a conductor 1 and a fluoroplastic insulation layer 2 arranged on the outside of the conductor 1, the conductor 1 comprising: tinned copper wire, a plurality of the tinned copper wires and / or the bulletproof wire reinforcing filling wires are twisted to form the conductor 1, the sheath comprising: a polyester fiber braided mesh 3 arranged on the outermost layer.

[0045] The present invention provides a highly flexible electric wire that breaks through the technical bottlenecks of flexible cables in mechanical strength, temperature resistance and dynamic durability. It can be used in frequently moving environments and solves the need for high temperature resistance. It ensures the wear resistance of the cable while enhancing the overall flexibility and extending the service life of the wire.

[0046] Preferably, the fluoroplastic insulation layer 2 exhibits high chemical stability and resistance to chemical corrosion, as well as fire resistance, high-temperature resistance, and flame retardancy. The fluoroplastic insulation layer 2 has a high oxygen index, resulting in a narrow flame spread and minimal smoke generation during combustion. This makes the cable suitable for use in public areas such as computer networks, subways, vehicles, and high-rise buildings. In the event of a fire, this provides sufficient evacuation time and reduces fire damage. The cable's insulation and sheath exhibit excellent aging resistance, maintaining stable electrical performance under various environmental conditions.

[0047] Preferably, the tinned copper wire includes: copper wire, a tinned layer is provided on the outside of the copper wire, and the wire diameter of the tinned copper wire is 0.04~0.08mm; the tinned layer can prevent the copper wire from being oxidized, and at the same time can better play a welding role during the welding process; multiple tinned copper wires and / or the bulletproof wire reinforcement filler wires are twisted to form a conductor part 1, and the wire diameter of the tinned copper wire is preferably 0.04, 0.06 and 0.08mm. Due to space limitations and for the sake of simplicity, the present invention no longer exhaustively lists the specific point values included in the range. The preferred wire diameter of the tinned copper wire can increase softness and bendability; and the bulletproof wire reinforcement filler wire is added during the twisting process of the conductor part 1 to increase the strength and stability of the conductor part 1.

[0048] Preferably, the core wire comprises:

[0049] At least one first core wire 4 having a specification of 28 to 32 AWG;

[0050] A plurality of second core wires 5 with specifications of 23 to 27 AWG.

[0051] The specifications of the first core wire 4 are preferably 28AWG, 30AWG and 32AWG. Due to space limitations and for the sake of simplicity, the present invention does not exhaustively list the specific point values included in the range. The first core wire 4 uses a thinner core wire with a specification of 28 to 32AWG (wire diameter 0.08 to 0.20 mm), which significantly reduces the bending stiffness and reduces the bending radius of the entire cable, adapting to high-frequency bending scenarios;

[0052] The specifications of the second core wire 5 are preferably 23AWG, 25AWG and 27AWG. Due to space limitations and for the sake of simplicity, the present invention does not exhaustively list the specific point values included in the range. The second core wire 5 uses a specification of 23-27AWG (wire diameter 0.41-0.64mm) as the supporting body. The mechanical skeleton is formed by the twisted structure of thick conductors to resist external tension and torsional deformation, and the tensile strength is improved; the core wire is twisted into multiple strands to disperse stress, avoid fatigue fracture of a single conductor, and improve the bending life under dynamic working conditions;

[0053] The second core wire 5 has a larger cross-sectional area (23-27AWG corresponds to 0.25-0.52mm0) and is used to carry the main current, meeting the high-power transmission requirements of 5-15A. The first core wire 4 (28-32AWG corresponds to 0.03-0.08mm0) is responsible for low-power signal transmission or redundant backup, achieving differentiated current distribution and improving current transmission efficiency.

[0054] Multiple thick second core wires 5 are twisted together to reduce the skin effect during high-frequency current transmission. Compared with a single thick second core wire 5, the AC resistance is reduced, the power utilization rate is improved, the skin effect loss is reduced, and the current transmission efficiency is improved;

[0055] The multi-core independent insulation design (fluoroplastic insulation layer) avoids the risk of short circuit between cores. Even if a single core breaks, the remaining cores can still maintain circuit connectivity.

[0056] Preferably, the cable core includes: at least one bulletproof wire reinforcement filler 6 and a first drainage wire 7, the first core wire 4 and the second core wire 5 are arranged on the outside of the bulletproof wire reinforcement filler 6, and a first drainage wire 7 is also provided on the outside of the bulletproof wire reinforcement filler 6, and the first drainage wire 7 is arranged between the second core wires 5; the first core wire 4, the second core wire 5 and the first drainage wire 7 are the same layer structure; the bulletproof wire reinforcement filler 6 serves as a central filler to disperse external tension and bending stress, thereby improving the tensile strength of the cable core and reducing the risk of conductor breakage caused by frequent movement; the bulletproof wire reinforcement filler 6 serves as a central filler to support the outer core wire structure, avoid compression and deformation of the core wire, and maintain the stability of the conductor twisted shape; the first drainage wire 7 is arranged between the second core wires 5, and conducts accumulated static charge or lightning surge into the earth, reducing the risk of electrolytic corrosion of the fluoroplastic insulation layer 2; compared with traditional external drainage wires, the built-in design shortens the charge migration path and improves the response speed.

[0057] Preferably, the protective layer includes: a tape layer 8, which is arranged on the outside of the first core wire 4, the second core wire 5 and the first drain wire 7; the tape layer 8 disperses external extrusion and friction stresses, thereby improving the compressive strength of the cable and is suitable for scenarios where the drag chain cable moves frequently; it cooperates with the core wire twisting structure to suppress the radial displacement of the internal conductor and reduce the probability of wear of the core wire insulation layer under dynamic working conditions.

[0058] Preferably, the cable core includes: a second flow line 9, which is arranged in the gap between the wrapping layer 8 and the first core wire 4, the second core wire 5 and the first flow line 7, and the cross-sectional area of the second flow line 9 is smaller than the cross-sectional area of the first flow line 7; the first flow line 7 arranged between the second core wires 5 suppresses internal electric field distortion, and the second flow line 9 arranged in the gap between the wrapping layer 8 and the first core wire 4, the second core wire 5 and the first flow line 7 blocks external electromagnetic intrusion, thereby realizing spatial electric field balance and double-layer electrostatic shielding; the first flow line 7 (with a larger cross-sectional area) is responsible for discharging high-intensity surge current, and the second flow line 9 (with a smaller cross-sectional area) focuses on conducting low-intensity high-frequency induced current, avoiding electrical corrosion of the insulation layer caused by the superposition of microcurrents, and realizing cross-sectional integral graded diversion. This design breaks through the reliability bottleneck of highly flexible cables in extreme electromagnetic environments and mechanical dynamic working conditions through the dual optimization of electromagnetic graded shielding and mechanical elastic adaptation.

[0059] Preferably, the protective layer includes: a silicone sheath 10, which is arranged on the outside of the wrapping layer 8. The silicone sheath 10 has a temperature resistance grade of up to 200°C, has excellent oil resistance and bending resistance, and can meet various ultra-high flexibility requirements.

[0060] The fluoroplastic insulation layer 2 and the silicone sheath 10 are both made of high temperature resistant materials. When used in a high temperature environment, the physical properties of the insulation and the sheath can be guaranteed not to suffer from brittle cracking caused by aging due to temperature rise.

[0061] Preferably, the polyester fiber woven mesh 3 includes: a polyester woven mesh, and the polyester woven mesh is arranged on the outside of the silicone sheath 10 by cross-weaving polyester filaments.

[0062] The cross-woven polyester filaments form a dense mesh armor, which improves the wear resistance, resists external friction damage, and prevents the silicone sheath 10 from directly contacting the rough surface and breaking; the high-modulus polyester filaments disperse local impact stress and reduce the risk of sheath puncture; the elastic modulus of the polyester filament woven mesh and the elastic modulus of the silicone sheath 8 form a rigidity-flexibility gradient, which suppresses the wrinkling of the sheath when the bending radius is ≤4D, thereby extending the service life of the wire; the cross-woven polyester filaments limit the radial expansion of the silicone sheath 10, preventing the silicone sheath 10 from bulging and deforming at high temperatures; the polyester fiber woven mesh 3 is resistant to high-temperature impact, and the cross-woven structure can enable the polyester fiber woven mesh 3 to maintain mechanical integrity under high-temperature working conditions.

[0063] On the other hand, the present invention also provides a method for manufacturing a highly flexible wire, wherein the method comprises the following steps:

[0064] The cable core manufacturing steps include the following manufacturing steps:

[0065] S1 twisting a plurality of tinned copper wires and / or bulletproof wire reinforcing filler wires to form a conductor member 1;

[0066] S2 extrude a fluoroplastic insulation layer 2 on the surface of the conductor 1 to form a core wire;

[0067] S3 twists multiple core wires and drain wires into a cable core;

[0068] The protective layer manufacturing steps include the following manufacturing steps:

[0069] S4 applies a tape layer 8 outside the cable core;

[0070] S5 presses and covers the silicone sheath 10 on the outside of the tape layer 8;

[0071] S6 is woven outside the silicone sheath 10 to form a polyester fiber braided mesh 3, thereby obtaining a highly flexible wire.

[0072] The present invention provides a method for manufacturing highly flexible electric wires, which breaks through the technical bottlenecks of flexible cables in mechanical strength, temperature resistance and dynamic durability. It can be used in frequently moving environments and solves the need for high temperature resistance. It ensures the wear resistance of the cable while enhancing the overall flexibility and extending the service life of the wires.

[0073] Preferably, the following steps are further included: the wrapping layer 8 in step S4 includes: a wrapping tape, the wrapping tape includes: aluminum foil or Mylar, and the wrapping tape is wrapped or dragged around the outer side of the cable core to form the wrapping layer 8;

[0074] The wrapping method integrates multiple core wires and drain wires into a concentric circle structure, eliminating gaps and suppressing displacement deformation under dynamic conditions;

[0075] The dragging method allows the aluminum foil / Mylar tape to form spiral reinforcement ribs, improving the cable's torsion resistance;

[0076] The tape layer 8 serves as a flexible isolation layer to disperse the extrusion force applied by the metal tape in the subsequent armoring process, thereby reducing the risk of damage to the core wire insulation layer.
