Description

Technical Field

[0001] This utility model relates to the field of wire and cable technology, and in particular to a high-strength tensile and wear-resistant wire. Background Technology

[0002] Electrical wires are conductors made of conductive materials (usually copper or aluminum) used to transmit electrical energy. They are covered with external insulation materials (such as PVC, rubber, plastic, etc.) to prevent current leakage and ensure safety. Electrical wires are widely used in power transmission, communications, household appliances, and industrial machinery. They come in many varieties, and their specifications vary depending on the application, load capacity, and environmental requirements.

[0003] Existing electrical wires still have some problems during use. For example, traditional wires often experience sheath wear, interlayer delamination, and conductor fatigue fracture under dynamic operating conditions. Current technologies typically use a single wear-resistant sheath or a simple reinforcing layer to protect the conductor, but these methods have certain limitations in practical applications. The bonding force between the sheath and the internal structure is often insufficient, causing interlayer separation to easily occur during repeated bending, thus affecting the overall structure and function of the wire. In addition, traditional wear-resistant sheaths often rely on surface protrusions to enhance wear resistance, but these protrusions gradually wear down after long-term use, causing a sharp decline in wear resistance, which in turn affects the long-term reliability and service life of the wire.

[0004] To address these issues, we provide a high-strength, tensile-resistant, and abrasion-resistant wire. Utility Model Content

[0005] The technical problem to be solved by this utility model is that the existing technology has the disadvantage that the sheaths used in wires have limited wear resistance and insufficient bonding force between the sheath and the internal structure, which easily affects the overall wear resistance and tensile strength of the wire. Therefore, we propose a high-strength tensile wear-resistant wire.

[0006] To achieve the above objectives, this application adopts the following technical solution: a high-strength tensile and wear-resistant wire, comprising a wear-resistant sheath, wherein spherical protrusions are fixedly connected to the surface of the wear-resistant sheath, a reinforcing strip is fixedly connected to the inner cavity of the wear-resistant sheath, a shell layer is fixedly connected to one side of the reinforcing strip, an insulating layer is fixedly connected to the inner cavity of the shell layer, holes are provided around the inner cavity of the insulating layer, an inner support layer is fixedly connected to the inner cavity of the holes, and a conductor layer is fixedly connected to the inner cavity of the inner support layer.

[0007] Preferably, an outer wear-resistant layer is fixedly connected to one side of the inner cavity of the wear-resistant sheath, a reinforcing support layer is fixedly connected to the inner cavity of the outer wear-resistant layer, and an inner adhesive layer is fixedly connected to the inner cavity of the reinforcing support layer. The wear-resistant sheath is composed of three composite layers: an outer wear-resistant layer, a reinforcing support layer, and an inner adhesive layer.

[0008] Preferably, the conductor layer is made of multiple strands of tin-plated copper wire twisted together, with a single wire diameter of 0.05~0.3mm.

[0009] Preferably, the inner support layer is woven from a mixture of aramid fibers and galvanized steel wire, and the inner support layer is used to improve the tensile strength of the conductor layer.

[0010] Preferably, the inner cavity of the hole is provided with anti-slip texture, and the surface of the inner support layer is provided with spiral ridges, with the anti-slip texture surface and the spiral ridge surface being in contact.

[0011] Preferably, the outer wear-resistant layer is made of polyethylene, the reinforcing support layer is made of glass fiber reinforced nylon, and the inner adhesive layer is made of modified TPU.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] 1. This utility model significantly improves the dynamic durability and resistance to mechanical damage of the wire through a multi-layer composite structure design. The three-layer composite sheath, combined with the spherical protrusions on the surface, forms a gradient wear-resistant system, which improves the wear resistance compared to the traditional single-layer sheath. At the same time, the aramid galvanized steel wire braided structure of the inner support layer and the anti-slip texture in the holes of the insulation layer form a three-dimensional interlock, solving the problem of interlayer slippage caused by repeated bending. The multi-strand tinned copper wire strands of the conductor layer work synergistically with the reinforcing strips of the inner support layer to greatly improve the tensile strength of the wire at break, meeting the requirements of extreme working conditions. In addition, the precise engagement of the spiral ridges and the anti-slip texture can effectively absorb torsional stress and effectively improve the service life of the wire.

[0014] 2. This utility model achieves long-term stable operation of the wire in complex environments through innovative structural design. The acid and alkali corrosion resistance of the outer wear-resistant polyethylene layer and the wide temperature resistance of the reinforcing support layer glass fiber nylon enable the wire to adapt to harsh environments such as outdoor and oil fields. The three-layer sheath adopts a co-extrusion one-time molding process, and the braiding of the inner support layer and the holes of the insulation layer are processed simultaneously through in-mold injection molding. This not only ensures the high performance of the product, but also significantly reduces the production cost. This design not only solves the problems of insufficient wear resistance and poor interlayer bonding of traditional wire sheaths, but also achieves a dual improvement in economic benefits and product reliability through optimized production processes.

[0021] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model. Example 1

[0022] Please see Figures 1-4 This utility model relates to a high-strength, tensile-resistant, and wear-resistant wire, comprising a wear-resistant sheath 1, which protects the inner conductor layer 8. Spherical protrusions 2 are fixedly connected to the surface of the nano-diamond wear-resistant sheath 1. The spherical protrusions 2 contain silicon carbide, aluminum oxide, and nano-diamond material, which disperses the sheath matrix and reduces the coefficient of friction. Reinforcing strips 3 are fixedly connected to the inner cavity of the wear-resistant sheath 1. The reinforcing strips 3 are triangular in shape, which can disperse external pressure or frictional stress to the shell layer 4, preventing local deformation or damage to the sheath and enhancing its strength. A shell layer 4 is fixedly connected to one side of strip 3. The shell layer 4 is used to cover the insulation layer 5 and connect to the outer wear-resistant sheath 1. The insulation layer 5 is fixedly connected to the inner cavity of the shell layer 4. The insulation layer 5 can insulate the wire. Holes 6 are opened around the inner cavity of the insulation layer 5. The holes 6 are used to install multiple sets of wires to facilitate connection with the outside and conduction. An inner support layer 7 is fixedly connected to the inner cavity of the holes 6. The function of the inner support layer 7 is to cover the conductor layer 8 and improve the tensile strength. The conductor layer 8 is fixedly connected to the inner cavity of the inner support layer 7. Example 2

[0023] Please see Figures 1-4Based on Example 1, an outer wear-resistant layer 9 is fixedly connected to one side of the inner cavity of the wear-resistant sheath 1. A reinforcing support layer 10 is fixedly connected to the inner cavity of the outer wear-resistant layer 9. An inner adhesive layer 11 is fixedly connected to the inner cavity of the reinforcing support layer 10. The wear-resistant sheath 1 is composed of three composite layers: the outer wear-resistant layer 9, the reinforcing support layer 10, and the inner adhesive layer 11. The wear-resistant sheath 1, composed of the outer wear-resistant layer 9, the reinforcing support layer 10, and the inner adhesive layer 11, combined with the spherical protrusion 2, can simultaneously meet the characteristics of bonding reliability, mechanical strength, and surface durability, thus protecting the inner conductor layer 8. The conductor layer 8 is made of multiple strands of tin-plated copper wire twisted together, with a single wire diameter of 0.05~0.3mm. The wire formed by the multiple strands of tin-plated copper wire twisted together is fixed to the inner cavity of the inner support layer 7, which can improve the tensile strength of the wire itself. The inner support layer 7 is made of a mixture of aramid fiber and galvanized steel wire. The inner support layer 7 is made of a porous thermoplastic elastomer buffer layer, which can improve the tensile strength of the conductor layer 8. The inner support layer 7 is used to improve the tensile strength of the conductor layer 8. The cavity of the hole 6 is provided with anti-slip texture 12, and the surface of the inner support layer 7 is provided with spiral ridges 13. The anti-slip texture 12 and spiral ridges 13 enable the inner support layer 7 and the insulation layer 5 to fit tightly together. The surface of the anti-slip texture 12 and the surface of the spiral ridges 13 are in contact. The outer wear-resistant layer 9 is made of polyethylene. The polyethylene material contacts the external wear medium through the outer surface of the wear-resistant sheath 1 and has wear-resistant and tear-resistant properties. The reinforcing support layer 10 is made of glass fiber reinforced nylon. The glass fiber reinforced nylon can bear the main mechanical strength, resist compression and shear, and disperse external loads. The inner bonding layer 11 is made of modified TPU. The modified TPU is firmly bonded to the shell layer 4, buffering stress and preventing delamination.

[0024] Working Principle: In operation, this high-strength, tensile-resistant, and wear-resistant wire utilizes a multi-strand tinned copper wire stranded structure in the conductor layer 8 for efficient power transmission. Simultaneously, the inner support layer 7, a braided layer of aramid fiber and galvanized steel wire, provides primary tensile protection. When the wire is subjected to external tension, the inner support layer 7, through its braided structure, evenly distributes the stress to the insulation layer 5. The anti-slip texture 12 within the holes 6 of the insulation layer 5 interlocks with the spiral ridges 13 on the surface of the inner support layer 7, forming a three-dimensional mechanical interlock that effectively prevents relative slippage between layers. The three-layer composite structure of the wear-resistant sheath 1 works synergistically. The polyethylene material of the outer wear-resistant layer 9 directly contacts the external abrasive medium. The spherical protrusions 2 on the surface reduce friction loss by reducing the contact area. The glass fiber reinforced nylon of the support layer 10 withstands mechanical impact and disperses compressive stress. The modified TPU of the inner adhesive layer 11 is tightly bonded to the shell layer 4 through chemical bonding to ensure the overall structural stability. The triangular design of the reinforcing strip 3 further converts external pressure into lateral dispersion force to avoid stress concentration. When the wire works under dynamic bending or torsion conditions, the porous buffer inner support layer 7 absorbs vibration energy. The combination of the spiral ridges 13 and the anti-slip texture 12 offsets torsional stress through micro-deformation, ultimately achieving long-term stable operation of the wire under high voltage, high wear and complex mechanical environment.

[0025] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
