Abstract

The utility model relates to the enamelled wire technological field, in particular to an enamelled copper wire, comprising a copper lead wire. An external surface of the copper lead wire is coated with a tinned layer, the external of which is coated with an insulation varnish layer. The enamelled copper wire of the utility model coats the tined layer on the external surface of the copper lead wire, having the oxidation prevention effect and thereby enhancing the product quality. In addition, the enamelled copper wire, which is easy to color and is excellent in high frequency performance and high baud rate performance and good in heat resistance, enables to directly carry out the welding work without removing varnish and to increase the operating efficiency. Furthermore, the enamelled copper wire has no salt water pinhole, and is suitable for high-speed coiling.

Description

Copper enameled wire

technical field

The utility model relates to the technical field of enameled wires, in particular to a copper enameled wire. the

Background technique

At present, high-temperature-resistant enameled wires have disadvantages such as poor paint film consistency, poor adhesion, and long peeling process. Because the paint used for existing enameled wires generally has a low temperature-resistant grade, it is difficult to adapt to the use environment of high-temperature-resistant products. Previously When copper enameled wire is used in the production and production of electronic components, because copper has a catalytic effect on the aging of paint skin, oxidation spots are easily formed on the copper surface. When using enameled wire for welding, it is more likely to have false welding and false welding, and the welding quality is not good. . the

Utility model content

The technical problem to be solved by the utility model is: in order to overcome the above existing problems, provide a copper enameled wire with reasonable structure, low production cost, good electrical conductivity, easy welding and anti-oxidation performance. the

The technical solution adopted by the utility model to solve the technical problem is: a copper enameled wire, including a copper wire, because copper has a catalytic effect on the aging of the paint, the outer surface of the copper wire is coated with a tin-plated layer, and the tin-plated layer The outside is coated with an insulating varnish layer. the

In order to achieve a better insulating effect, the insulating paint layer is a polyurethane paint insulating layer. the

This kind of copper enameled wire is mainly used for winding of communication devices, coils for computerized machines, intermediate frequency and high frequency coils, and also suitable for enameled stranded wires and various relays and inductance coils. the

The beneficial effect of the utility model is that the copper enameled wire of the utility model is coated with a tin-plated layer on the outer surface of the copper wire, which plays an anti-oxidation effect, thereby improving the quality of the product, and is easy to color, has excellent high-frequency performance, and can Direct welding work without paint removal can improve work efficiency, high baud performance is superior, heat resistance is good, and there is no salt water pinhole and it is also suitable for high-speed winding. the

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is further described. the

Fig. 1 is a structural representation of the utility model. the

In the figure 1. Copper wire, 2. Tin-plated layer, 3. Insulating varnish layer. the

Detailed ways

Now in conjunction with accompanying drawing, the utility model is described in further detail. These drawings are all simplified schematic diagrams, and only schematically illustrate the basic structure of the utility model, so they only show the configurations related to the utility model. the

The copper enameled wire shown in Fig. 1 includes a copper wire 1, the outer surface of the copper wire 1 is coated with a tin-plated layer 2, and the outer surface of the tin-plated layer 2 is coated with an insulating varnish layer 3, and the insulating varnish layer 3 is a polyurethane varnish insulating layer. the

Compared with the conventional enameled wire, the copper enameled wire of the utility model has higher tensile strength, so it is closer to the higher requirements of the modern motor industry on the mechanical performance of the enameled wire. the

Inspired by the above ideal embodiment according to the utility model, through the above description content, relevant staff can completely make various changes and modifications within the scope of not deviating from the technical idea of the utility model. The technical scope of this utility model is not limited to the content in the description, but must be determined according to the scope of the claims. the
