[0027] Wires are wire products used to transmit electrical energy, information and realize electromagnetic energy conversion. As the main carrier of power transmission, wires are widely used in electrical equipment, power transmission, construction, communications and other aspects. They are closely related to all sectors of social and economic development. They play a vital basic role in the current industrialization, informatization and even the development of future intelligent industries. The quality of wires directly affects the quality of the project and the safety of life and property of consumers.

[0028] A slingshot wire in the related technology, with publication number CN216119590U, includes a wire body, the middle part of the wire body is spirally coiled into a spiral segment, and the two ends of the spiral segment are respectively a first straight line segment and a second straight line segment; the wire body includes a wire group, a shielding layer, a polyether TPU outer coating layer, a first cotton thread, a second cotton thread and a third cotton thread, the wire group includes a first wire, a second wire and a third wire connected in pairs, the first wire, the second wire and the third wire are arranged in an inverted triangle structure, and the third wire is located at the bottom; the shielding layer is coated on the periphery of the first wire, the second wire, the third wire, the first cotton thread, the second cotton thread and the third cotton thread, and the polyether TPU outer coating layer is extruded on the periphery of the shielding layer, and has high structural strength, good hydrolysis resistance and high resilience.

[0029] However, a slingshot wire in the related art has poor insulation performance against external heat in a high temperature environment or when a fire occurs outside the wire, which may cause the filling material and insulating material inside the wire to soften or even melt, thereby causing the wire to fail to work normally.

[0030] Based on this, in order to improve the problems in the related art, the embodiments of the present application provide the following solutions.

[0031] Please also read Figures 1 to 3 The embodiment of the present application provides a high-temperature resistant Teflon wire, including an outer shell 1, an insulating layer 2, a heat-insulating layer 3 and a wire core 4. The outer shell 1 is used to protect and support the material inside the wire, and the heat-insulating layer 3 is used to isolate external heat to prevent the material temperature inside the heat-insulating layer 3 from being too high when the wire works in a high-temperature environment and affecting the normal operation of the wire.

[0032] Please also read Figures 1 to 3 The insulating layer 2 is sleeved on the outer surface of the wire core 4, the heat insulation layer 3 is arranged inside the shell 1, the insulating layer 2 and the wire core 4 are both arranged inside the heat insulation layer 3, and a filler 5 is filled between the inner wall of the heat insulation layer 3 and the outer wall of the insulating layer 2. The filler 5 is made of polyurethane foam plastic, and a plurality of reinforcing ribs 51 are arranged inside the filler 5. The reinforcing ribs 51 are made of nylon. The heat insulation layer 3 is made of silicone rubber, the wire core 4 is made of silver-plated copper wire, the insulating layer 2 is made of polypropylene, and the shell 1 is made of Teflon. The outer peripheral surface of the filler 5 is sleeved with a waterproof membrane 6, and the outer peripheral surface of the waterproof membrane 6 abuts against the inner peripheral surface of the heat insulation layer 3, and the waterproof membrane 6 is made of polyethylene.

[0033] From the above, it can be seen that the high-temperature resistant Teflon wire provided by the embodiment of the present application, the insulating layer 2 made of silicone rubber has better high-temperature resistance and heat insulation performance. When the wire works in a high-temperature environment, the heat insulation layer 3 can effectively prevent external heat from being transferred into the inside of the heat insulation layer 3, which can ensure that the material inside the heat insulation layer 3 is less affected by the external temperature, thereby ensuring that the wire can work normally in a certain high-temperature environment; the silver-plated copper wire has better conductivity than pure copper wire, which can reduce the heat generated by the wire itself when it is used; the Teflon material has good corrosion resistance and high mechanical strength, which can effectively protect the internal material. In addition, the Teflon material has a small friction coefficient and is less prone to wear than other materials, which can increase the service life of the wire; the polyurethane foam has a good corrosion resistance and high mechanical strength, which can effectively protect the internal material. Polyurethane foam plastic has good elasticity, softness and compression strength. When the wire is squeezed by external objects, the filler 5 made of polyurethane foam plastic can absorb the impact force and pressure to protect the insulating layer 2 and the wire core 4. The filler 5 also isolates each insulating layer 2 to prevent friction between the insulating layers 2 when the wire is twisted, resulting in wear on the outer peripheral surface of the insulating layer 2; nylon material has good tensile strength and mechanical strength. When the two ends of the wire are set up, the wire will be pulled by its own gravity. The reinforcing ribs 51 can withstand greater pulling force, enhance the tensile strength of the wire, and avoid breakage of the wire; the waterproof membrane 6 can prevent liquid and water vapor outside the waterproof membrane 6 from entering the waterproof membrane 6 to corrode the wire material inside the waterproof membrane 6.

[0034] In some embodiments, please refer to Figures 1 to 3 A shielding net 7 is sleeved on the outer peripheral surface of the heat insulation layer 3, and the material of the shielding net 7 is pure copper plated with tin.

[0035] With such arrangement, the shielding net 7 can shield the electromagnetic waves outside the electric wire, thereby preventing them from interfering with the electric signals transmitted by the electric wire, thereby improving the transmission quality of the electric signals of the electric wire.

[0036] Optionally, in some embodiments, see Figure 2 and Figure 3 An aluminum foil 8 is sleeved on the outer circumference of the shielding net 7 , and the outer circumference of the aluminum foil 8 abuts against the inner circumference of the housing 1 .

[0037] With such arrangement, when a fire occurs outside the wire, the outer shell 1 may be damaged due to the high temperature. At this time, the aluminum foil 8 can isolate the flame so that the part of the wire inside the aluminum foil 8 is not in contact with the open flame and air, thereby avoiding the wire from catching fire and enhancing the fire resistance of the wire.

[0038] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
