Description

A kind of novel magnetic core

Technical field

The utility model relates to magnetic core technical field, relates in particular to a kind of novel magnetic core.

Background technology

Magnetic core is the sintering magnetic metal oxide by various iron oxide compositions of mixtures, and in prior art, FERRITE CORE is for coil and the transformer of various electronic equipments.For example, manganese-zinc ferrite and nickel-zinc ferrite are typical magnetic core array materials, wherein, manganese-zinc ferrite has the feature of high magnetic permeability and high magnetic flux density, when the frequency lower than 1MHz, there is more low-loss characteristic, nickel-zinc ferrite has high unit area impedance, less than the characteristics such as low magnetic permeability of hundreds of, and in the frequency higher than 1MHz, produce compared with low-loss etc.

The material of magnetic core and structure are the key factors that affects magnetic core performance.Current, for the research of magnetic core, mostly concentrate on improvement and the exploitation aspect of core material, less for the research of core structure, and in engineering application, the structure of magnetic core is very important one of considers in whole electronic device design.In order to meet the application needs of different application occasion, improve effective work area of magnetic core, guarantee stability and the reliability of the electromagnetic property of magnetic core, be that those skilled in the art need the technical problem of facing in application.

Utility model content

The problem existing for prior art, the utility model proposes a kind of novel magnetic core, has effectively increased the work area of magnetic core, has improved stability and the reliability of the electromagnetic property of magnetic core.

A kind of novel magnetic core, comprise: base plate, wrapping post and two lateral columns, base plate is rectangular configuration, wrapping post is fixed on base plate middle part, wrapping post length direction is consistent with floor length direction, and two lateral columns are arranged symmetrically with and are fixed on the both sides of baseplate width direction with respect to wrapping post; The two ends of wrapping post length direction have preset distance between the two ends of floor length direction, the two ends of wrapping post length direction are cambered surface, two ends in floor length direction form extratensive type open slot, open slot is comprised of inner side cambered surface and two side planes, inner side cambered surface is formed to downward-extension by the cambered surface at wrapping post length direction two ends, and two side planes are arranged symmetrically with respect to the axis of wrapping post.

Preferably, the angle between two side planes is 30～50 °.

Preferably, described angle is 36～44 °.

Preferably, the distance between the two ends of wrapping post length direction to the two ends of floor length direction is less than the distance between wrapping post to two lateral column.

In the utility model, two ends in floor length direction form extratensive type open slot, open slot is comprised of inner side cambered surface and two side planes, and inner side cambered surface is formed to downward-extension by the cambered surface at wrapping post length direction two ends, and two side planes are arranged symmetrically with respect to the axis of wrapping post.By open slot is set, effectively increased the work area of magnetic core, improved stability and the reliability of the electromagnetic property of magnetic core.
