Magnetic element

Abstract

The invention provides a magnetic element, which comprises a wire winding rack, two conductive windings and a magnetic core group, wherein the wire winding rack has an inner ring structure; a through channel is formed in the inner ring structure, and more than two protrusion parts are arranged at each of two ends of the inner ring structure; the two conductive windings are symmetrically arranged on a first surface and a second surface of the wire winding rack; each conductive winding is provided with two conductive parts which are adjacent to each other; each conductive part is provided with a first through hole, a second through hole, notches which are respectively positioned at the periphery of the first through hole and the periphery of the second through hole and respectively correspond to the protrusion parts of the inner ring structure, and more than two pins; and the magnetic core group passes through the through channel and is combined with the wire winding rack. By improving the structures of the wire winding rack and the conductive windings, the conductive parts in the conductive windings and the pins cannot deviate, so that the quality of the magnetic element can be improved.

Description

technical field [0001] The present invention relates to magnetic elements, and in particular to magnetic elements having winding structures. Background technique [0002] Generally speaking, there are often many magnetic components in electrical equipment, such as transformers, inductance components, etc., and in order to adapt to the thinning of electrical equipment, the magnetic components and the conductive windings used inside also need to develop towards a thinner trend to reduce electrical equipment. of the overall volume. [0003] Taking a transformer as an example, it is known that wires are wound on the winding base as the primary winding and secondary winding of the transformer. Since the winding base must reserve a certain space for the primary and secondary windings to be wound, therefore It is difficult to reduce the volume of the transformer, thereby affecting its power density. Therefore, in order to reduce the volume of the transformer, copper sheets are us...

Problems solved by technology

[0007] But, for the substrate 2, it can fix the pins of the first copper sheet 12 and the second copper sheet 13, but it cannot fix the first copper sheet 12 and the second copper sheet 13, that is, it cannot solve the problem of the first copper sheet 12 and the second copper sheet 13. The offset between the second copper sheet 13

In addition, due to the additional configuration of the substrate 2, the production cost will be increased, such as the raw material cost of the substrate 2 and the labor cost for producing it
