Abstract
Description
Technical Field
[0001] The present application relates to the technical field of enameled copper wires, and in particular to a 200-level bending-resistant high-frequency pulse enameled copper wire. Background Art
[0002] Enameled wire is the most representative product of electronic wire. It is a main type of winding wire, consisting of a conductor and an insulating layer. The bare wire is annealed and softened, then painted and baked for many 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] At present, in real life, the enameled copper wire needs to be bent. At present, when a large bending force is applied to the enameled copper wire, the paint on the outer wall of the enameled copper wire is easily damaged. The rupture of the paint easily leads to a decrease in the insulation performance of the enameled copper wire. This is mainly because when the enameled copper wire is bent, the outer protective layer is pulled, resulting in a decrease in its thickness, thereby causing the performance of the protective layer to decrease. Utility Model Content

[0007] The protective layer 1 and the protective layer 2 are both multi-layer structures.
[0008] With the above structure, the enameled copper wire body can be easily protected by setting a multi-layer structure.

[0013] The second protective layer comprises an anti-skid layer fixedly connected to the second insulating layer, and the outer wall of the anti-skid layer is fixedly connected to the braided layer.
[0014] With the above structure, the anti-slip layer can be arranged to avoid sliding between the anti-slip layer and the second insulating layer, and the braided layer can be arranged to improve the overall performance of the protective cover.
[0015] The outer wall of the braided layer is fixedly connected with a heat insulation layer.
[0016] With the above structure, the braided layer is protected by the heat insulating layer to prevent the braided layer from being damaged by excessive external temperature.
[0017] The outer wall of the heat insulation layer is fixedly connected with a wear-resistant layer.
[0018] With the above structure, the overall wear resistance of the protective sleeve is improved by providing the wear-resistant layer.
[0019] The material of the protective polymer layer is a polyethylene composite layer, and the outer wall of the wear-resistant layer is covered with a lubricating layer.
[0020] With the above structure, the friction between the wear-resistant layer and the bending tool is reduced by providing the lubricating layer.
[0021] In summary, the beneficial effects of this application are as follows:
[0022] 1. The present application arranges two protective components in the protective layer of the enameled copper wire, and arranges a lubricating layer outside the wear-resistant layer in the second protective component. The lubricating layer is formed by a lubricating oil composite, thereby reducing the wear of the wear-resistant layer and avoiding damage to the external wear-resistant layer during bending, thereby improving the protective performance of the cable.
[0023] 2. The present application ensures the insulation performance of the copper wire by setting two insulating layers in the protective cover of the copper wire, effectively avoiding the situation where the insulation performance of the copper wire is destroyed when the copper wire protective cover is damaged, and further improves the overall toughness of the protective cover by setting the braided layer, thereby improving the overall finish of the protective cover.
