Flat wire continuously-wound linear coil and inductor

Abstract

The invention provides a flat wire continuously-wound linear coil and an inductor. The flat wire continuously-wound linear coil comprises a coil A and a coil B. The winding directions of the coil A and the coil B are opposite, and the coil A and the coil B are formed by winding the same flat wire. The flat wire is of a quadrangular structure, the cross section of the flat wire is rectangular, andchamfers are arranged on the four edges of the flat wire respectively, so that the cross section of the flat wire is of an octagonal structure. The chamfers provide a space for pressing deformation ofthe flat wire, so that the thickness of the inner side of the bent part of the flat wire after deformation does not exceed the thickness of the flat wire, two adjacent single-coil coils can be tightly attached together, and a gap between the two adjacent single-coil coils is eliminated. When the iron core is installed in the coil, injection molding can be directly conducted between the coil and the iron core, gaps in the coil do not need to be filled with chemical reagents any more, the process of coating the interior of the coil with the chemical reagents is omitted, cost is saved, and meanwhile use of polluting chemical reagents is reduced.

Description

technical field [0001] The invention relates to the technical field of inductance components, in particular to a linear coil and an inductor wound with flat wires. Background technique [0002] The reactor is composed of a coil and an iron core. Among them, the coil is divided into two types: series and parallel. And series coils are widely used in filters for boosting voltage of choke coils and improving power factor. In the prior art, the series vertical winding of the coils is basically realized by copper bar welding, which has the problems of consuming materials and manpower. [0003] In addition, in the existing technology, when the iron core is installed in the coil, the coil needs to be injected, but the flat wire in the existing coil will have a large gap outside the coil and thicken the inside. When the flat wire is bent laterally, the inner wall of the flat wire will bear a huge bending stress, and the thickness of the flat wire is thinner, so the bending stress ...

AI Technical Summary

Problems solved by technology

At the same time, since the bending stroke outside the bending of the flat wire is much larger than the average bending stroke of the flat wire, the result is that the outer flat wire of the bending angle is stretched and thinned, so that the flat wire is not compact enough when winding

[0004] In order to prevent the plastic from flowing out of the gap, chemical reagents need to be coated in the coil, but the steps of this process are complicated, and the chemical reagents also have pollution
