a magnetic element

Abstract

The invention discloses a magnetic element. The magnetic element comprises a winding skeleton, a magnetic core group and a conducting winding, wherein a mounting channel passing through two ends of the winding skeleton is arranged at the center of the winding skeleton, the side face of the winding skeleton is depressed inwards to form a wire slot encircling the outer ring of the mounting channel, and locating rings protruding outwards are arranged at the centers of two end faces of the winding skeleton respectively; the magnetic core group is composed of two magnetic cores sleeved at two ends of the winding skeleton; the conducting winding is arranged on at least one end face of the winding skeleton, locating holes capable of being sleeved on the locating rings are formed in the conducting winding, a bending part is further arranged on one side edge of the conducting winding, and the bending part stretches out of the magnetic core group. The magnetic element is provided with an effective heat dissipation structure, and a primary winding and a secondary winding can be accurately positioned, so that the magnetic element is convenient for volume automatic production.

Description

technical field [0001] The invention relates to the technical field of magnetic components, in particular to a magnetic component with a cooling and positioning structure. Background technique [0002] The current design of magnetic components of switching power supplies, such as transformers, etc., in order to reduce the size of the device, often use figure 1 In the shown structure, a transformer is formed by combining the primary winding 500 and the secondary copper winding 600, and then cooperating with the magnetic cores 400a and 400b. The primary side of the transformer is usually high-voltage and low-current, which requires more winding turns. The secondary side of the transformer is low-voltage and high-current, which requires fewer winding turns. Copper sheet windings are generally used. [0003] This scheme has the following disadvantages: [0004] 1. The primary winding needs to be wound manually. When the number of turns is large, the consistency of the winding ...

AI Technical Summary

Problems solved by technology

[0004] 1. The primary winding needs to be wound manually. When the number of turns is large, the consistency of the winding size cannot be guaranteed;

[0005] 2. The relative position of the secondary copper sheet winding and the primary winding cannot be accurately positioned, especially after multiple primary and secondary windings are sandwiched, batch consistency is difficult to guarantee;

[0006] 3. There is no effective heat dissipation structure on the magnetic element, and the heat cannot be dissipated quickly when the magnetic element is in use, which affects the performance and life of the magnetic element
