Description

Technical Field

[0001] This utility model relates to the field of tin-plated copper wire technology, specifically a tensile-resistant tin-plated copper wire. Background Technology

[0002] Tinned copper wire refers to copper wire with a thin layer of tin plated on its surface. Tinned copper wire is relatively soft, has good conductivity, and compared with bare copper wire, it has stronger corrosion resistance and oxidation resistance, which can greatly extend the service life of low-voltage cables.

[0003] Tin-plated copper wire has long faced the dual challenges of mechanical properties and corrosion resistance. Traditional processes use a single tin plating layer, which can provide basic conductive protection, but it is insufficient in mechanical protection. When tin-plated copper wire is bent or stretched, stress concentration can cause the core wire to break, and it also has weak chemical corrosion protection. Utility Model Content

[0004] This invention provides a tensile-resistant tin-plated copper wire. Through the synergistic effect of the filler layer and the winding layer, the tensile strength is improved. The filler layer is made of silicone rubber composite material wrapped around the outer wall of each tin-plated copper wire body. The silicone rubber composite material has excellent elasticity and resilience, which can effectively absorb and disperse external mechanical stress, and prevent the core wire from breaking due to stress concentration when the tin-plated copper wire body is bent or stretched. Through the first protective layer and the second protective layer, a double-layer protection is achieved. The first protective layer provides basic physical protection against mechanical wear and ultraviolet aging. The second protective layer enhances chemical protection capabilities, resists acid and alkali corrosion, and prevents environmental media from intruding and causing failure. At the same time, through the nano-organic silicon protective layer, the penetration of corrosive media such as acids, alkalis and salt spray is further blocked, improving the acid and alkali corrosion resistance.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a tensile-resistant tin-plated copper wire, comprising: The tin-plated copper wire body has multiple components; A filler layer, wrapping around the outer wall of each tin-plated copper wire body; The winding layer wraps around the outer wall of the filler layer; A protective layer is provided on the winding layer.

[0006] Furthermore, each of the tin-plated copper wire bodies includes a core wire, a high tin content layer, a tin alloy layer, a nano-organic silicon protective layer, and an insulating layer. The high tin content layer is wrapped around the outer wall of the core wire, the tin alloy layer is wrapped around the outer wall of the high tin content layer, the nano-organic silicon protective layer is wrapped around the outer wall of the tin alloy layer, and the insulating layer is wrapped around the outer wall of the nano-organic silicon protective layer.

[0007] Furthermore, each of the insulating layers is made of TPE elastomeric insulating material.

[0008] Furthermore, the material of the winding layer is polyester tape.

[0009] Furthermore, the protective layer includes a first protective layer and a second protective layer, wherein the second protective layer is wrapped around the outer wall of the winding layer, and the first protective layer is wrapped around the outer wall of the second protective layer.

[0010] Furthermore, the first protective layer is made of polyurethane rubber, and the second protective layer is made of polyvinyl chloride.

[0011] This invention provides a tensile-resistant tin-plated copper wire. It has the following beneficial effects: (1) The tensile strength of the tin-plated copper wire can be improved through the synergistic effect of the filler layer and the winding layer. The filler layer is made of silicone rubber composite material to wrap the outer wall of each tin-plated copper wire body. The silicone rubber composite material has excellent elasticity and resilience, which can effectively absorb and disperse external mechanical stress and prevent the core wire from breaking due to stress concentration when the tin-plated copper wire body is bent and stretched.

[0012] (2) The tensile tin-plated copper wire plays a double protection role through the first protective layer and the second protective layer. The first protective layer provides basic physical protection to resist mechanical wear and ultraviolet aging. The second protective layer enhances chemical protection capabilities, resists acid and alkali corrosion, and prevents environmental media from intruding and causing failure. At the same time, through the nano-organic silicon protective layer, it further blocks the penetration of corrosive media such as acid, alkali and salt spray, and improves acid and alkali corrosion resistance.

The second protective layer 402 is wrapped around the outer wall of the wrapping layer 3, and the first protective layer 401 is wrapped around the outer wall of the second protective layer 402.

[0025] In this embodiment, the first protective layer 401 and the second protective layer 402 provide double protection. The first protective layer 401 provides basic physical protection against mechanical wear and ultraviolet aging, while the second protective layer 402 enhances chemical protection, resists acid and alkali corrosion, and prevents environmental media from intruding and causing malfunctions.

[0026] Specifically, the first protective layer 401 is made of polyurethane rubber, and the second protective layer 402 is made of polyvinyl chloride.

The nano-organosilicon protective layer 104 is a siloxane polymer nano-coating, which provides a chemical inert barrier and can block the penetration of corrosive media such as acids, alkalis and salt spray. The first protective layer 401 and the second protective layer 402 provide a double-layer protection.
