Description

Technical Field

[0001] This utility model relates to the field of stranded copper electronic wires, and specifically to a durable stranded copper electronic wire. Background Technology

[0002] Stranded copper electronic wires are widely used in the internal connections and signal transmission of electronic equipment. They are key components that ensure the stable operation of electronic equipment, and their structural stability, conductivity, and durability directly affect the overall performance of the equipment.

[0003] Existing stranded copper electronic wire conductors mostly use a simple stranding method. To improve stability, the number of single wires is often increased, but loosening is still prone to occur, and the chaotic conductive path leads to uneven conductivity. The conductor and the reinforcing layer are in direct contact. Some use wear-resistant materials to improve performance, but it is difficult to solve the problem of severe friction between the two, which shortens the service life. The protective structure is mostly a single insulation layer. Although it can achieve basic insulation, it has defects in wear resistance, scratch resistance and anti-interference performance, and cannot adapt to complex use scenarios. Utility Model Content

[0004] The purpose of this invention is to address the above-mentioned defects and provide a durable stranded copper electronic wire. It improves the conductor structure design, interlayer friction optimization, and protective tensile strength structure, thus solving the technical problems of loose conductors and uneven conductivity, severe interlayer wear, and insufficient protective tensile strength in the prior art.

[0005] The objective of this utility model is achieved through the following means:

[0006] A durable stranded copper electronic wire includes a conductor, a reinforcing layer, an insulating layer, and a friction-reducing layer. The conductor consists of a central monofilament and six surrounding monofilaments, which are evenly distributed in a honeycomb pattern around the central monofilament to form a hexagonal structure. Both the central and surrounding monofilaments are stranded copper monofilaments, and the diameter of the inner layer of stranded copper monofilaments is larger than that of the outer layer. The reinforcing layer, which is a high-strength aramid fiber layer, wraps around the conductor. The insulating layer, which includes an inner insulating layer and an outer insulating layer, is disposed outside the reinforcing layer. The inner insulating layer is a highly elastic insulating layer, and the outer insulating layer is a wear-resistant insulating layer. The inner insulating layer adheres to the outside of the reinforcing layer, and the outer insulating layer wraps around the outside of the inner insulating layer. The friction-reducing layer, which is a solid lubricating coating, is disposed between the conductor and the reinforcing layer and adheres to both the outside of the conductor and the inside of the reinforcing layer. The central monofilament, surrounding monofilament, reinforcing layer, inner insulating layer, outer insulating layer, and friction-reducing layer are coaxially arranged. It also includes a shielding tensile layer, which is disposed outside the insulating layer and is a metal wire winding layer formed by spirally winding the metal wire along the outside of the insulating layer. The shielding tensile layer is covered with a polyimide scratch-resistant layer. Furthermore, it includes elastic tensile elements. Several grooves are formed along the length of the reinforcing layer, inner insulating layer, outer insulating layer, shielding tensile layer, polyimide scratch-resistant layer, and friction-reducing layer. These grooves penetrate the reinforcing layer, inner insulating layer, outer insulating layer, shielding tensile layer, polyimide scratch-resistant layer, and friction-reducing layer. The grooves are evenly distributed along the circumference of the electronic wire. The elastic tensile elements are embedded in the grooves and are in close contact with the grooves. Several wear-resistant protrusions are evenly distributed along the length of the cable on the outer side of the insulating layer, and these protrusions are integrally formed with the insulating outer layer.

[0007] The honeycomb-shaped conductor structure, combined with the difference in diameter between the inner and outer monofilaments, improves the overall structural stability and conductivity of the conductor, avoiding loose conductors and uneven conductivity. The anti-friction layer reduces the relative wear between the conductor and the reinforcing layer, extending the service life of both. The combination of a highly elastic insulating inner layer and a wear-resistant insulating outer layer provides dual insulation protection with buffering and wear resistance. The shielding tensile layer and elastic tensile elements enhance the tensile strength and anti-interference ability of the electronic wire. The polyimide scratch-resistant layer and wear-resistant protrusions further strengthen the outer layer protection, significantly improving the overall durability of the electronic wire and solving the shortcomings of traditional electronic wires in terms of structural stability, wear resistance, and tensile strength.

[0008] Furthermore, the outer surfaces of both the central monofilament and the surrounding monofilament are covered with a graphene layer, the graphene layer is attached to the outer surfaces of the central monofilament and the surrounding monofilament, and a friction-reducing layer is attached to the outside of the graphene layer.

[0009] The graphene layer enhances electrical and thermal conductivity as well as corrosion resistance. At the same time, the friction-reducing layer further reduces frictional losses with the reinforcing layer, avoids single-filament wear, extends the conductor's service life, and strengthens the core conductivity of the electronic wire.

[0010] Furthermore, the wear-resistant protrusions are spherical structures, the spacing between two adjacent wear-resistant protrusions is equal, and the outer surface of the wear-resistant protrusions smoothly transitions to the outer surface of the insulating outer layer.

[0011] The wear-resistant protrusions increase the wear-resistant contact area, and the spherical structure disperses external wear. The smooth transition design avoids stress concentration, making the wear more uniform, significantly improving the wear resistance life of the outer insulating layer, and ensuring the integrity of the outer protective layer.

[0012] Furthermore, an anti-corrosion coating is provided at the twisted gap between the central monofilament and the surrounding monofilament, the anti-corrosion coating fills the gap, and the anti-corrosion coating adheres to the graphene layer.

[0013] The anti-corrosion coating fills the gaps to prevent moisture and impurities from entering and avoid conductor corrosion; the graphene layer forms a synergistic protection, ensuring the conductivity stability of the conductor and improving the applicability of the electronic wire in harsh environments such as humid conditions.

[0014] Furthermore, a mesh adhesive layer is provided between the inner insulating layer and the outer insulating layer, with the upper and lower ends of the adhesive layer respectively attached to the inner insulating layer and the outer insulating layer;

[0015] The mesh bonding layer enhances the bond between the two layers and prevents delamination; the mesh structure expands the bonding area and improves stability, allowing the elastic buffer of the inner insulating layer and the wear-resistant protection of the outer insulating layer to be fully utilized, ensuring the overall protective effect of the insulation layer.

[0016] Furthermore, the polyimide scratch-resistant layer is bonded to the shielding tensile layer, and an annular groove is formed on the surface of the polyimide scratch-resistant layer, the annular groove being staggered from the wear-resistant protrusions;

[0017] The polyimide scratch-resistant layer is scratch-resistant, and the annular grooves reduce weight and improve flexibility. The staggered distribution of the wear-resistant protrusions avoids mutual interference, which not only retains the protective properties of the scratch-resistant layer, but also enhances the bending adaptability of the electronic wires, thereby improving the overall protection and usage flexibility of the outer layer.

[0018] The beneficial effects of this invention are as follows: By using a central monofilament and six honeycomb-distributed surrounding monofilaments as the conductor, with the inner monofilament diameter larger than the outer layer, the conductor structure is stabilized and the conductive path is optimized, offering advantages such as resistance to deformation and high conductivity, thus solving the problems of looseness and uneven conductivity in traditional conductors; by placing a friction-reducing layer between the conductor and the reinforcing layer, the relative friction between the two is reduced, extending the lifespan of both the conductor and the reinforcing layer, thus solving the problem of severe wear; by combining a highly elastic inner insulating layer with a wear-resistant outer layer, a shielding tensile layer, and a polyimide scratch-resistant layer, multiple layers of protection are achieved, offering advantages such as insulation, wear resistance, scratch resistance, and anti-interference, thus solving the problem of single-layer protection; by embedding elastic tensile elements in the groove and providing wear-resistant protrusions on the insulating outer layer, tensile strength and wear resistance are improved, offering advantages such as adaptability to complex scenarios, thus solving the problem of insufficient tensile strength and wear resistance.

[0023] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0024] In this embodiment, refer to Figures 1-3The present invention relates to a durable stranded copper electronic wire, comprising a conductor, a reinforcing layer 4, an insulating layer, and a friction-reducing layer 3. The conductor consists of a central monofilament 1 and six surrounding monofilaments 2, which are evenly distributed in a honeycomb pattern around the central monofilament 1 to form a hexagonal structure. Both the central monofilament 1 and the surrounding monofilaments 2 are stranded copper monofilaments, and the diameter of the inner stranded copper monofilaments formed by the central monofilament 1 and the surrounding monofilaments 2 is larger than the diameter of the outer stranded copper monofilaments. The reinforcing layer 4 is wrapped around the outside of the conductor and is a high-strength aramid fiber layer. The insulating layer is disposed outside the reinforcing layer 4 and includes an inner insulating layer 5 and an outer insulating layer 6. The inner insulating layer 5 is a highly elastic insulating layer, and the outer insulating layer 6 is a wear-resistant insulating layer.

The friction-reducing layer 3 is disposed between the conductor and the reinforcing layer 4 and is a solid lubricating coating. The friction-reducing layer 3 is attached to the outside of the conductor and the inside of the reinforcing layer 4. The monofilament 2, reinforcing layer 4, inner insulating layer 5, outer insulating layer 6, and friction-reducing layer 3 are coaxially arranged; it also includes a shielding tensile layer 8, which is disposed outside the insulating layer. The shielding tensile layer 8 is a metal wire winding layer, with the metal wire spirally wound along the outside of the insulating layer to form the shielding tensile layer 8; the outer side of the shielding tensile layer 8 is covered with a polyimide scratch-resistant layer 9; it also includes an elastic tensile element 11, the reinforcing layer 4, the inner insulating layer 5, the outer insulating layer 6, the shielding tensile layer 8, the polyimide scratch-resistant layer 9, and the friction-reducing layer. The interior of layer 3 has several grooves 10 along its length. The grooves 10 penetrate the reinforcing layer 4, the inner insulating layer 5, the outer insulating layer 6, the shielding tensile layer 8, the polyimide anti-scratch layer 9, and the friction-reducing layer 3. The grooves 10 are evenly distributed along the circumference of the electronic wire. The elastic tensile element 11 is embedded in the groove 10 and is in contact with the groove 10. The outer side of the outer insulating layer 6 has several wear-resistant protrusions 12 evenly distributed along the length of the cable. The wear-resistant protrusions 12 are integrally formed with the outer insulating layer 6.

[0026] The graphene layer enhances electrical and thermal conductivity as well as corrosion resistance. At the same time, the friction-reducing layer 3 further reduces frictional losses with the reinforcing layer 4, preventing single-filament wear, extending the conductor's service life, and strengthening the core conductivity of the electronic wire.

[0027] like Figure 1 and Figure 2 As shown, the wear-resistant protrusion 12 has a spherical structure, the spacing between two adjacent wear-resistant protrusions 12 is equal, and the outer surface of the wear-resistant protrusion 12 smoothly transitions with the outer surface of the insulating outer layer 6.

[0028] The wear-resistant protrusions 12 increase the wear-resistant contact area, and the spherical structure disperses external force wear; the smooth transition design avoids stress concentration, making wear more uniform, significantly improving the wear resistance life of the outer insulating layer 6, and ensuring the integrity of the outer protective layer.

[0029] like Figure 1 As shown, an anti-corrosion coating is provided at the twisted gap between the central monofilament 1 and the surrounding monofilament 2. The anti-corrosion coating fills the gap and adheres to the graphene layer.

[0030] The anti-corrosion coating fills the gaps to prevent moisture and impurities from entering and avoid conductor corrosion; the graphene layer forms a synergistic protection, ensuring the conductivity stability of the conductor and improving the applicability of the electronic wire in harsh environments such as humid conditions.

[0032] The mesh bonding layer 7 enhances the bonding force between the two layers and prevents delamination; the mesh structure expands the bonding area and improves stability, allowing the elastic buffer of the inner insulating layer 5 and the wear-resistant protection of the outer insulating layer 6 to be fully utilized, ensuring the overall protective effect of the insulation layer.

[0033] like Figure 1 and Figure 3 As shown, the polyimide scratch-resistant layer 9 is bonded to the shielding tensile layer 8, and an annular groove is formed on the surface of the polyimide scratch-resistant layer 9. The annular groove and the wear-resistant protrusion 12 are staggered.

[0034] The polyimide scratch-resistant layer 9 is scratch-resistant, and the annular groove reduces weight and improves flexibility. The staggered distribution with the wear-resistant protrusions 12 avoids mutual interference, which not only retains the protective properties of the scratch-resistant layer, but also enhances the bending adaptability of the electronic wires, thereby improving the overall protection and usage flexibility of the outer layer.

[0035] The working principle of a durable stranded copper electronic wire in this embodiment is as follows: the central monofilament 1 and the surrounding monofilament 2 of the conductor form a conductive core; the graphene layer enhances conductivity and protection; the anti-corrosion coating seals gaps and prevents corrosion; the friction-reducing layer 3 reduces friction between the conductor and the reinforcing layer 4; the reinforcing layer 4 and the elastic tensile element 11 enhance tensile strength; the mesh bonding layer 7 fixes the inner insulating layer 5 and the outer insulating layer 6, respectively playing the roles of elastic buffering and wear resistance; the shielding tensile layer 8 achieves shielding and tensile strength; the polyimide scratch-resistant layer 9 and the wear-resistant protrusions 12 strengthen the outer layer protection; during use, it is adapted to the wiring requirements of the corresponding electronic equipment to avoid excessive bending and pulling, ensuring that all structures work together effectively.
