Description

Technical Field

[0001] This utility model relates to the field of flat copper wire technology, specifically a wear-resistant modified nonwoven fabric double-film-coated flat copper wire. Background Technology

[0002] Flat copper wire is a type of copper conductor with a flat cross-section. Compared to round copper wire, its flat shape allows for a larger current-carrying area within the same volume, thus improving space utilization. It typically also exhibits higher tensile strength and bending resistance, making it suitable for applications requiring strong mechanical stress. Furthermore, the flat structure of flat copper wire provides a larger heat dissipation area, helping to reduce system temperature and improve equipment lifespan and stability. Additionally, flat copper wire is easier to install in confined spaces, especially in applications requiring multi-dimensional circuit connections, where space can be utilized more efficiently. In summary, flat copper wire offers a range of advantages in modern engineering design, particularly in applications with limited space, high heat dissipation requirements, and high mechanical stress. Although its cost may be relatively high, its performance improvements often bring long-term economic benefits and increased reliability.

[0003] Flat copper wire, due to its flat structure, is suitable for fixed power transmission lines or connecting cables for mobile electrical appliances, and is widely used in industries such as metallurgy, power, petrochemicals, electronics, and automobile manufacturing. The advantages of flat copper wire are that its flat cross-section can improve space utilization, facilitate the surface laying and longitudinal stacking of cables, and provide good flexibility and low resistance. These characteristics make flat copper wire an ideal choice for a variety of industrial applications. Currently available flat copper wires, although they have good flexibility and conductivity, are still widely used in various industries.

[0004] However, the existing flat copper wires do not have effective separation between their internal copper conductors, which can easily lead to mutual interference, resulting in unstable operation. Furthermore, their poor wear resistance and shielding properties make them prone to wear and interference, severely affecting their service life, increasing maintenance costs, and potentially causing unexpected service interruptions. Therefore, a wear-resistant modified nonwoven fabric double-film-coated flat copper wire is proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a wear-resistant modified non-woven fabric double-film-coated flat copper wire. This solves the problem that the internal copper conductors are not effectively separated, which can easily lead to mutual interference, resulting in unstable operation, poor wear resistance and shielding, and easy wear and interference. This, in turn, seriously affects the service life of the flat copper wire, increases maintenance costs, and may lead to unexpected service interruptions.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a wear-resistant modified nonwoven fabric double-film-coated flat copper wire, comprising a copper wire conductor, wherein an isolation and protective structure is provided on the outside of the copper wire conductor;

[0007] The isolation and protection structure includes an isolation tube fixedly connected to the outside of the copper wire conductor, a filling layer fixedly connected to the outside of the isolation tube, an insulating layer fixedly connected to the outside of the filling layer, a shielding layer fixedly connected to the outside of the insulating layer, a flame-retardant layer fixedly connected to the outside of the shielding layer, and a wear-resistant layer provided on the outside of the flame-retardant layer.

[0008] Furthermore, the number of copper wire conductors is four, and the isolation tube is a square hollow tube structure.

[0009] Furthermore, both the filling layer and the wear-resistant layer are non-woven fabrics, and their thicknesses are consistent.

[0010] Furthermore, the shielding layer is a double-layer aluminum foil film.

[0011] Furthermore, the flame-retardant layer is a halogen-containing flame-retardant material.

[0012] Furthermore, the insulating layer is made of rubber, and the copper wire conductor, the insulating tube, and the filling layer are all disposed on the inner side of the insulating layer.

[0013] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0014] This wear-resistant modified nonwoven fabric double-film-coated flat copper wire achieves effective separation through the setting of an isolation and protection structure, which can avoid mutual interference between the four groups of copper wire conductors and ensure operational stability. At the same time, it achieves the effects of filling gaps, flame retardant protection, anti-interference protection and wear-resistant protection, thereby effectively improving service life, reducing maintenance costs, and avoiding unexpected service interruptions, making it more suitable for long-term use.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1 to 3 In this embodiment, a wear-resistant modified nonwoven fabric double-film-coated flat copper wire includes a copper wire conductor 1, and an isolation and protection structure is provided on the outside of the copper wire conductor 1.

[0021] The isolation and protection structure includes an isolation tube 2 fixedly connected to the outside of the copper wire conductor 1, a filling layer 3 fixedly connected to the outside of the isolation tube 2, an insulation layer 4 fixedly connected to the outside of the filling layer 3, a shielding layer 5 fixedly connected to the outside of the insulation layer 4, a flame-retardant layer 6 fixedly connected to the outside of the shielding layer 5, and a wear-resistant layer 7 set on the outside of the flame-retardant layer 6. By setting up the isolation and protection structure, effective separation is achieved, which can prevent the four sets of copper wire conductors 1 from affecting each other, ensuring operational stability. At the same time, it achieves the effects of filling gaps, flame-retardant protection, anti-interference protection, and wear-resistant protection, thereby effectively improving service life, reducing maintenance costs, and avoiding unexpected service interruptions, which is more conducive to long-term use.

[0022] The copper wire conductor 1 consists of four groups, and the isolation tube 2 is a square hollow tube structure. The four isolation tubes 2 can wrap around and completely isolate the four groups of copper wire conductor 1, thereby achieving effective separation, avoiding mutual interference between the four groups of copper wire conductor 1, and ensuring operational stability.

[0023] The filling layer 3 and the wear-resistant layer 7 are both non-woven fabrics with the same thickness. The non-woven filling layer 3 and the wear-resistant layer 7 can fill the gap between the isolation tube 2 and the insulation layer 4 to provide additional support and protection, reduce vibration and impact during transportation and installation, and have high strength and wear resistance, effectively protecting the insulation layer 4 from damage by external forces such as tension, pressure and compression.

[0024] Meanwhile, the shielding layer 5 is a double-layer aluminum foil film. The shielding layer 5 made of double-layer aluminum foil film has high airtightness and shielding performance, which can achieve the effect of anti-interference protection and play the role of cover and barrier.

[0025] In addition, the flame retardant layer 6 is a halogen-containing flame retardant material. The flame retardant layer 6 made of halogen-containing flame retardant material has a good flame retardant effect and improves safety performance in the event of a fire.

[0026] It should be noted that halogenated flame retardant materials release hydrogen halides when burning. These hydrogen halides can capture active free radicals, thereby delaying or extinguishing the flame and achieving the purpose of flame retardancy. Commonly used halogenated flame retardant materials include polyvinyl chloride, chloroprene rubber, chlorosulfonated polyethylene, and ethylene propylene rubber.

[0027] It should be understood that the insulation layer 4 is made of rubber, and the copper wire conductor 1, the isolation tube 2 and the filling layer 3 are all located inside the insulation layer 4. The rubber insulation layer 4 achieves the effect of insulation and protection.

[0028] The working principle of the above embodiments is as follows:

[0029] In use, the four sets of isolation tubes 2 can wrap around and completely isolate the four sets of copper wire conductors 1, thus achieving effective separation and preventing mutual interference between the four sets of copper wire conductors 1, ensuring operational stability. Among them, the non-woven fabric filling layer 3 and the wear-resistant layer 7 can fill the gap between the isolation tube 2 and the insulation layer 4 to provide additional support and protection, reduce vibration and impact during transportation and installation, and at the same time, have high strength and wear resistance, effectively protecting the insulation layer 4 from damage by external forces such as tension, pressure and compression. Meanwhile, the shielding layer 5 made of double-layer aluminum foil film has high airtightness and shielding, and can achieve the effect of anti-interference protection, so as to play a role in shielding and barrier. In addition, the flame-retardant layer 6 made of halogen-containing flame-retardant material has good flame-retardant effect, improves safety performance in fire conditions, thereby effectively increasing service life, reducing maintenance costs, and avoiding unexpected service interruptions, which is more conducive to long-term use.
