Problems solved by technology

Limited by the material of the skeleton and the injection molding process, the thickness of the blade and the tube wall is usually greater than 0.7mm, occupying a large proportion of the winding space, accounting for about 34.2% of the winding window space of the magnetic core, and becoming a technical bottleneck for transformer miniaturization

Abstract

The invention discloses a magnetic element, a metal ring-shaped winding and a manufacturing method thereof. The metal ring-shaped winding includes a first flat plate part, a winding support part and a through hole, and the winding support part is arranged on the first flat plate part. And the winding supporting part is perpendicular to the first flat part, a through hole is formed in the middle of the first flat part and the winding supporting part, the first flat part and the winding supporting part both surround the through hole and form a ring.

Description

technical field [0001] The present invention relates to a magnetic element, a metal ring winding and a preparation method thereof, in particular to a metal ring winding in which a winding space is jointly formed by a flat plate part and a winding support part and a preparation method thereof, and A magnetic element with the metal toroidal winding. Background technique [0002] In order to meet the development needs of high output current, the transformer secondary winding usually adopts copper sheet structure, such as figure 1 The copper sheet Q shown. The primary winding P adopts a winding structure and is wound on the skeleton B. In order to improve the eddy current loss, the primary and secondary windings are generally designed as a staggered structure. In the transformer, the skeleton B is used as the winding support of the primary winding P, and the winding space needs to be formed by the blades and the tube wall. Limited by the material of the skeleton and the inje...
