Magnetic core and applicable magnetic element of magnetic core

Abstract

The invention discloses a magnetic core and an applicable magnetic element of the magnetic core. The magnetic core at least comprises an oval center post and two side posts, wherein the oval center post is provided with a long shaft and a short shaft; the length of the long shaft is greater than that of the short shaft; the two side posts are oppositely arranged at two sides of the oval center post, are connected with the oval center post, and define at least one winding space together with the oval center post. Through the arrangement of the oval center post, the magnetic core has the advantages that the winding space is enlarged, the diameter of a wining coil is increased, the temperature of a winding solenoid is lowered, the winding solenoid is prevented from being oversize, and the safety distance between the winding solenoid and a reel is increased to accord with the safety specification.

Description

technical field [0001] The invention relates to a magnetic core, in particular to a magnetic core with an elliptical central column structure and an applicable magnetic element. Background technique [0002] Magnetic components are indispensable basic components for the operation of electronic devices, and can be widely used in various electronic devices. With the development trend of miniaturization, high power, multi-function and popularization of electronic devices, magnetic components must also be designed in a flat design, improve overall performance, increase structural diversity and reduce costs to meet the needs of electronic devices. [0003] see Figure 1A , which is a schematic diagram of a magnetic core structure applied to an existing magnetic element. Generally speaking, the magnetic core 1 has a central column 11 and two side columns 12 , and the central column 11 and the two side columns 12 define a winding space 13 for coil winding.

AI Technical Summary

Problems solved by technology

[0005] The main purpose of the present invention is to provide a magnetic core and its applicable magnetic components, so as to solve the problem that the existing magnetic core adopts a circular central column structure, which causes the winding space to be small, the wire diameter of the winding coil to be small, and the The wire package is too large and the temperature is high, it is not easy to dissipate heat, the distance between the winding package and the winding frame is not enough, the safety problem is caused, and the magnetic induction intensity and magnetic core loss are not good.
