Description

Technical Field

[0001] The utility model relates to the technical field of enameled wires, in particular to a high-shielding enameled wire. Background Art

[0002] Enameled wire is a main type of winding wire, which consists of two parts: conductor and insulation layer. The bare wire is annealed and softened, then painted and baked several times. However, it is not easy to produce products that meet both standard requirements and customer requirements. It is affected by factors such as raw material quality, process parameters, production equipment, and environment. Therefore, the quality characteristics of various enameled wires are different, but they all have four major properties: mechanical properties, chemical properties, electrical properties, and thermal properties.

[0003] In the prior art, most enameled wires are susceptible to external electromagnetic interference during use due to the lack of good shielding performance, resulting in signal quality degradation or interference, thereby affecting the stability and reliability of the system.

[0004] Therefore, those skilled in the art provide a high-shielding enameled wire to solve the problems raised in the above background technology. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcomings existing in the prior art and to propose a high-shielding enameled wire. When the enameled wire is in use, a first shielding layer and a second shielding layer are arranged outside the enameled wire body and they are superimposed to form a more complete shielding structure, which can effectively block external electromagnetic interference from entering the interior of the enameled wire and improve the stability and reliability of signal transmission.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A high-shielding enameled wire comprises an enameled wire body, a first shielding layer is arranged outside the enameled wire body, a second shielding layer is arranged outside the first shielding layer, an insulating layer is arranged outside the second shielding layer, a flame retardant layer is arranged outside the insulating layer, a corrosion resistant layer is arranged outside the flame retardant layer, a tensile layer is arranged outside the corrosion resistant layer, and a wear resistant layer is arranged outside the tensile layer;

[0008] Through the above technical solution, when the enameled wire is in use, by setting the first shielding layer and the second shielding layer outside the enameled wire body and stacking them, a more complete shielding structure can be formed, which can effectively block external electromagnetic interference from entering the interior of the enameled wire and improve the stability and reliability of signal transmission.

[0009] Furthermore, the first shielding layer and the second shielding layer are both made of braided copper foil and aluminum foil;

[0010] Through the above technical solution, by weaving copper foil and aluminum foil on the outside of the enameled wire, the interference of electromagnetic waves can be blocked to ensure the stability and reliability of signal transmission.

[0011] Furthermore, the insulating layer is made of polyvinyl chloride material;

[0012] Through the above technical solution, the polyvinyl chloride material has good insulation performance and dielectric strength, which can effectively protect the conductor inside the wire and improve the electrical performance and safety of the enameled wire.

[0013] Furthermore, the flame retardant layer is made of cross-linked polyethylene material;

[0014] Through the above technical solution, at high temperature, cross-linked polyethylene can slow down the spread of fire and effectively protect the enameled wire from flames.

[0015] Further, the corrosion-resistant layer is made of polypropylene material;

[0016] Through the above technical solution, the corrosion-resistant layer made of polypropylene material can effectively protect the enameled wire from being corroded by chemical solutions, acids, alkalis and other substances, thereby extending its service life.

[0017] Furthermore, the tensile layer is made of polyimide material;

[0018] Through the above technical solution, polyimide is used as a tensile layer to effectively enhance the tensile properties of the enameled wire, improve its mechanical strength, and prevent breakage or deformation.

[0019] Furthermore, the wear-resistant layer is made of polytetrafluoroethylene material;

[0020] Through the above technical scheme, the use of polytetrafluoroethylene as a wear-resistant layer can effectively reduce the wear and abrasion of the surface of the enameled wire and extend its service life.

[0021] Furthermore, anti-sliding blocks are evenly spaced outside the wear-resistant layer;

[0022] Through the above technical solution, the anti-slip block can provide additional friction and reduce the risk of sliding and slipping on the surface of the enameled wire.

[0023] The utility model has the following beneficial effects:

[0024] 1. The utility model proposes a high-shielding enameled wire. Compared with the existing high-shielding enameled wire, when the high-shielding enameled wire is used, a first shielding layer and a second shielding layer are arranged outside the enameled wire body, and they are superimposed to form a more complete shielding structure, which can effectively block external electromagnetic interference from entering the interior of the enameled wire and improve the stability and reliability of signal transmission.

[0025] 2. The utility model proposes a high-shielding enameled wire. Compared with the existing high-shielding enameled wire, when the high-shielding enameled wire is in use, the corrosion-resistant layer arranged externally can effectively prevent the corrosion of the enameled wire by external corrosive substances, thereby extending the service life; the flame-retardant layer effectively inhibits the spread of flames and reduces fire losses; the tensile layer increases the tensile resistance and mechanical strength of the enameled wire, reduces damage caused by external forces, and further extends the service life.
