A flat soft magnetic ferrite magnetic core

Abstract

The invention relates to a flat soft magnetic ferrite magnetic core, which relates to the technical field of magnetic cores, in particular to a flat soft magnetic ferrite magnetic core. The flat softmagnetic ferrite magnetic core comprises a first magnet and a second magnet, and the first magnet includes a top plate, a left column and a right column; the left column and the right column are vertically arranged at the left and right ends of the lower end face of the top plate, the second magnet comprises a bottom plate and an intermediate pillar, wherein the central position of the upper end face of the bottom plate is vertically provided with the intermediate pillar, the shape of the top plate is consistent with the shape of the bottom plate, the lower end faces of the left pillar and theright pillar are fixedly connected with the two sides of the bottom plate, and the intermediate pillar is arranged between the left pillar and the right pillar. As the technical scheme is adopt, theflat soft magnetic ferrite magnetic core has the advantages of simple structure, reasonable design, high integration level, flattening, small distribution parameters, low loss and high reliability; through the mutual cooperation and installation of the first magnet and the second magnet with flat design, the flat soft magnetic ferrite magnetic core is simple to combined and assemble, and modular combination optimizes the magnetic circuit.

Description

technical field The invention relates to the technical field of magnetic cores, in particular to a flattened soft ferrite core. Background technique The magnetic core refers to a sintered magnetic metal oxide composed of various iron oxide mixtures. For example, manganese-zinc ferrite and nickel-zinc ferrite are typical core body materials. Manganese-zinc ferrites are characterized by high magnetic permeability and high magnetic flux density, and have low loss characteristics. Nickel-zinc ferrite has the characteristics of extremely high resistivity and low magnetic permeability of less than a few hundred. Ferrite cores are used in coils and transformers in various electronic devices. The ferrite core is made of non-metallic magnetic material with dense and homogeneous ceramic structure, and has low coercive force, also known as soft ferrite. It consists of iron oxide (Fe2O3) and oxide or carbonate compounds of one or several other metals (eg manganese, zinc, nickel, ma...
