Problems solved by technology

[0002] At present, with the popularization of electronic products in daily life, the demand for inductors is also increasing. At present, low-power inductors can basically realize automatic production, while high-power inductors are basically produced by hand, tooling, etc. Equipment-assisted production is the mainstay, so there are low production efficiency, high labor costs, and human factors affecting product quality.

Embodiment Construction

[0013] Such as Figure 1 to Figure 3 As shown, a combined PFC inductor includes two first magnetic cores 1, two second magnetic cores 2 and two coil windings 3, the two first magnetic cores are arranged in parallel up and down, and the two second magnetic cores The two magnetic cores are arranged side by side between two first magnetic cores and are located on both sides of the length of the first magnetic core. on the second core. The two second magnetic cores are first glued and fixed with one of the first magnetic cores, then the coil windings are placed on the second magnetic cores, and finally the other first magnetic core is glued and installed. The coil windings can be The winding is good, which solves the difficulty of making the winding, the most important process in the manufacturing process of the inductor. In addition, the coil winding is made of flat wire, and the flat wire can be wound on the improved spring machine first, with high winding efficiency and good ...

Abstract

The invention discloses a combined type PFC inductor. The combined type PFC inductor comprises two first magnetic cores, two second magnetic cores and two coil windings; the two first magnetic cores are placed up and down in parallel; the two second magnetic cores are arranged between the two first magnetic cores side by side and positioned on the two sides of the length of the first magnetic cores; the end planes of the second magnetic cores are glued and fixed with the first magnetic cores; the coil windings are nested on the second magnetic cores; and the coil windings are wound by flat wires. The manufacturing difficulty of the most working procedure of winding in the manufacturing process of the inductor is solved, so that production efficiency is improved.

Description

technical field [0001] The present invention relates to inductors, in particular to PFC inductors. Background technique [0002] At present, with the popularization of electronic products in daily life, the demand for inductors is also increasing. At present, low-power inductors can basically realize automatic production, while high-power inductors are basically produced by hand, tooling, etc. Equipment-assisted production is mainly used, so there are low production efficiency, high labor costs, and human factors affecting product quality. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a combined PFC high-power inductor that can be conveniently and automatically produced. [0004] In order to solve the above technical problems, the present invention adopts the following technical scheme: a combined PFC inductor, comprising two first magnetic cores, two second magnetic cores and two coil windings, the two first ...
