Winding wire, winding and preparation method of winding wire

Abstract

The invention discloses a winding wire, a winding and a preparation method of the winding wire. The winding wire comprises a wire body and an insulated structure, and the wire body is wound and wrapped by the insulated structure; the insulated structure comprises a first insulated layer with the first width and a second insulated layer with the second width; the second insulated layer has an X-axis direction and a Y-axis direction perpendicular to the X-axis direction, the first insulated layer is arranged on the second insulated layer in the direction parallel to the X-axis direction, and the first width is smaller than the second width; one part of the wire body is arranged on the second insulated layer in the direction parallel to the X-axis direction and is not covered with the first insulated layer, and the first insulated layer and the second insulated layer wind and wrap the other part of the wire body in the Y-axis direction.

Description

technical field [0001] The present invention relates to a wire winding and a preparation method thereof, in particular to a wire winding capable of both insulation and automatic processing and a preparation method thereof. Background technique [0002] In order to meet safety regulations, existing switching power supply transformers mostly use three-layer insulated pull wires as winding wires to meet insulation requirements. Although this method meets the needs of safety regulations, the material cost of the three-layer insulated pull wire is relatively high, which is not conducive to reducing production costs; moreover, the three-layer insulated pull wire has a problem of high hardness, and when it is wound into a winding It is easy to cause the space of the transformer to be too large, which is not conducive to improving the power density of the transformer. To sum up, if the general-purpose three-layer insulated pull wire is used as the winding, the competitiveness of th...

Problems solved by technology

Although this approach meets the needs of safety regulations, the material cost of the three-layer insulated pull wire is relatively high, which is not conducive to reducing production costs; moreover, the three-layer insulated pull wire has a problem of high hardness, and when it is wound into a winding It is easy to cause the space of the transformer to be too large, which is not conducive to improving the power density of the transformer

In summary, if the general-purpose three-layer insulated pull wire is used as the winding, the competitiveness of the overall product will be reduced, so it is urgent to develop a winding and its preparation method that overcomes the above defects
