Abstract

This utility model provides one combination FERRITE CORE, it includes the core print seat of annular, core print seat outer peripheral face bottom outward expansion forms stair-stepping expanded ring, core print seat internal ring top is fitted together to the inner core of cylinder, inner core center is provided with the core bore run through up and down, core print seat internal ring bottom is provided with core body, core body is provided with center pillar, center pillar is two, middle column bottom is fixed on core body, two center pillar opposite side sidewalls after Gu Ding are cambered surface, and the extrados of two center pillars is relative, and center pillar is provided with the fixing hole run through up and down.This utility model uses modularity to be conducive to the accurate production of part, and after making combination, magnetic core using effect is more preferable, and die sinking simultaneously is simpler, produces precision higher, can be greatly improved the competitiveness of product.

Description

A kind of combination FERRITE CORE

Technical field

This utility model relates to magnetic core technical field, refers in particular to a kind of combination FERRITE CORE.

Background technology

Coiling in FERRITE CORE and can be made into inducer or transformator, the material trademark of FERRITE CORE is more, several What shape is the most various, has cylindricality, I-shaped, hat, single hole, diplopore, four holes, U shape, tank shape, E shape, EI shape, EC Shape, RM shape, PQ shape, EP shape etc., the magnetic core of each shape is from becoming a series of, and FERRITE CORE can be according to not Same magnetic parameter, selects different materials and shape due to low magnetic loss at high frequencies, and they are widely used in switching mode Power supply, radio-frequency transformer and inducer.Variously-shaped and size FERRITE CORE is applied to high frequency electric source and high quality communication The inducer in market, pulse transformer, high frequency transformer, and noise filter etc..Ferritic maximum feature is high osmosis, Good temperature characterisitic, and low attenuation rate.But existing magnetic core is integrally formed mostly, it makes precision and is difficult to reach preferable effect Really, and complex magnetic core die sinking cost is high, and mould is easily damaged.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art, it is provided that a kind of die sinking is simple, produce that precision is high, make FERRITE CORE is preferably combined by effect.

For achieving the above object, technical scheme provided by the utility model is: a kind of combination FERRITE CORE, it includes Having the core print seat of annular, core print seat outer peripheral face bottom outward expansion to form stair-stepping expanded ring, core print seat internal ring top is chimeric circle The inner core of cylindricality, inner core center is provided with the core bore run through up and down, and core print seat internal ring bottom is provided with core body, and core body is provided with center pillar, Center pillar is two, and middle column bottom is fixed on core body, and two center pillar opposite side sidewalls after fixing are cambered surface, two center pillars Extrados is relative, and center pillar is provided with the fixing hole run through up and down.

The center of circle of described fixing hole is positioned on same centrage with the center of circle of center pillar cambered surface.

The stepped perforation matched with fixing hole it is provided with bottom described core body.

This utility model, after using such scheme, uses split modularized production, and streamline assembles the most again, uses mould Massing is conducive to the accurate production of part, and after making combination, magnetic core using effect is more preferable, and die sinking simultaneously is simpler, produces precision more Height, can be greatly improved the competitiveness of product.

Accompanying drawing explanation

Fig. 1 is overall structure schematic diagram of the present utility model.

Detailed description of the invention

Below in conjunction with all accompanying drawings, the utility model is described in further detail, and preferred embodiment of the present utility model is: ginseng Seeing accompanying drawing 1, a kind of FERRITE CORE that combines described in the present embodiment includes the core print seat 1 of annular, core print seat 1 outer peripheral face bottom to External expansion forms stair-stepping expanded ring 2, and core print seat 1 internal ring top is fitted together to the inner core 3 of cylinder, and inner core 3 center is provided with Under the core bore 4 that runs through, core print seat 1 internal ring bottom is provided with core body 5, is provided with, bottom described core body 5, the ladder matched with fixing hole 7 Shape is bored a hole, and core body 5 is provided with center pillar 6, and center pillar 6 is two, is fixed on core body 5 bottom center pillar 6, two center pillars 6 after fixing Opposite side sidewall is cambered surface, and the extrados of two center pillars 6 is relative, and center pillar 6 is provided with the fixing hole 7 run through up and down, described The center of circle of fixing hole 7 is positioned on same centrage with the center of circle of center pillar 6 cambered surface.The present embodiment uses split modularized production, so After again streamline assemble, use modularity to be conducive to the accurate production of part, after making combination, magnetic core using effect is more preferable, opens simultaneously Mould is simpler, produces precision higher, can be greatly improved the competitiveness of product.

The embodiment of the above is only the preferred embodiment of this utility model, not limits reality of the present utility model with this Executing scope, therefore the change that all shapes according to this utility model, principle are made, all should contain at protection domain of the present utility model In.
