Problems solved by technology

However, for example, the winding of a traditional inductor is usually composed of multiple sets of coils connected in parallel, and each set of coils will have a coating layer, which results in a larger volume of the winding of the traditional inductor and requires a larger winding. Therefore, the volume of traditional inductors is relatively large, which is not conducive to miniaturization, and because each coil of the winding of traditional inductors will have a coating layer, the copper loss of the winding will increase and the efficiency of traditional inductors will decrease.

Abstract

The invention relates to an inductor, comprising: at least one first magnetic core comprising a connecting part, a first cylinder and a second cylinder, the first cylinder and the second cylinder being arranged on the top surface of the connecting part, and a winding groove being arranged between the first cylinder and the second cylinder; the second magnetic core is adjacent to the first magnetic core; and each winding is formed by winding a single metal conductive sheet for at least one circle, each winding is sleeved on the corresponding first column body and is partially positioned in the winding groove of the corresponding first magnetic core, and the thickness of the winding is less than or equal to the width of the winding groove and is greater than 0.9 time of the width of the winding groove.

Description

technical field [0001] This application is an inductor, especially an inductor that can be miniaturized, and can improve efficiency and heat dissipation. Background technique [0002] In electronic products, various magnetic components, such as transformers and inductance components, are often used to meet the required circuit design through the principle of electromagnetic induction. However, for example, the winding of a traditional inductor is usually composed of multiple sets of coils connected in parallel, and each set of coils will have a coating layer, which results in a larger volume of the winding of the traditional inductor and requires a larger winding. Therefore, the volume of the traditional inductor is relatively large, which is not conducive to miniaturization, and because each coil of the winding of the traditional inductor has a coating layer, the copper loss of the winding increases and the efficiency of the traditional inductor decreases. [0003] Therefo...
