Abstract

The invention provides an inductor assembly. The inductor assembly is formed by multiple inductors in a packaging manner, wherein each inductor comprises an inductance coil and two E-shaped magnetic cores; each magnetic core comprises a bottom column, and a middle column and two side columns protruding from the bottom column to the same side; the bottom column, the middle column and the side columns jointly form a magnetic core plane; the two side columns are positioned on the two sides of the middle column respectively; the opening ends of the two magnetic cores face each other; the middle columns of the two magnetic cores face each other; the side columns of the two magnetic cores prop against each other; two magnetic cores form two magnetic loops; the inductance coils are wound around the middle columns of the corresponding two magnetic cores; an air gap is formed between the middle columns of the two magnetic cores; the inductors are tightly arranged on the magnetic core planes in a rectangular array manner; and the magnetic cores of every two adjacent inductors prop against each other. The invention also provides a manufacturing method for the inductor assembly. The external electromagnetic interference of the inductor assembly is greatly lowered; the space utilization rate is obviously improved; and the inductor assembly has a good magnetic shielding effect even if the inductor assembly is small in volume.

Description

technical field

[0001] The present invention relates to the technical field of inductors, and more particularly relates to an inductor component and a manufacturing method thereof. Background technique

[0002] Electronic and electrical products are rapidly developing towards miniaturization and multi-functionalization. In these products, power inductors are relatively large in size, especially when multiple power inductors are required, and their space utilization rate is lower. Many It hinders the miniaturization of the product to a certain extent; moreover, the magnetic shielding effect of these power inductors is poor, and it is easy to generate electromagnetic interference to other circuits, especially when the product integrates various functional modules, it will cause various problems to the multifunctional design and realization of the product. an inescapable limitation. Therefore, the existing inductors need to be further improved. Contents of the invention [...
