Description

A kind of novel ferrite magnetic core

Technical field

The utility model relates to a kind of magnetic core for transformer, has been specifically related to a kind of novel ferrite magnetic core.

Background technology

Be accompanied by small-sized, the lightweight of electronic device, efficient and high performance, as the loop part of these electronic transformers manganese-zinc ferrite core used, require further miniaturization, high performance.Communication is E type ferrite magnetic core with what use in pulse transformer, this E type ferrite magnetic core is larger at useful flux area, volume under identical condition of work, the energy that he transmits is so also just larger, therefore FERRITE CORE product is according to the different requirements of power, a series of specification products of different volumes have been produced, and the volume of same series of products is larger, the height of product is also just higher, has brought inconvenience to installation and the use in later stage.

Moreover in manufacture course of products, between product, contact area is excessive, between product, air penetrability is low, easily produces distortion, cracking; The surperficial oxygen uptake contacting between product is inhomogeneous, causes product lumber recovery low.

Utility model content

For solving the problems of the technologies described above, we have proposed a kind of novel ferrite magnetic core, its object: do not changing under the prerequisite of self material, at volume with highly do not increase in the situation that, useful flux area is being met the demands; During sintering, between product, air penetrability is high, can not occur to deform because ventilative rate variance between product causes, the situation such as cracking, and the surperficial oxygen uptake contacting between product is even, and product lumber recovery is high.

For achieving the above object, the technical solution of the utility model is as follows:

A novel ferrite magnetic core, comprises main body, the E type that is shaped as of main body, and the width of the left arm of main body, right arm and middle arm is 6～7mm, and the length of main body is 42～45mm, and the height of main body is 22～28mm, and the thickness of main body is 29～35mm;

The end face of the left arm of main body, right arm and middle arm is the cambered surface that radius is 17mm,

The both sides of main body bottom surface are respectively equipped with first protruding block, main body bottom surface be provided with second protruding block, the middle part of the second protruding block is provided with groove;

The first protruding block end face to the maximum normal distance of main body bottom surface is greater than the second protruding block end face to the maximum normal distance of main body bottom surface.

Preferably, other corners of main body are circular-arc.

Pass through technique scheme, the E type that is shaped as of main body, the left arm of main body, the width of right arm and middle arm is 6～7mm, the length of main body is 42～45mm, the height of main body is 22～28mm, the thickness of main body is 29～35mm, the left arm of main body, the end face of right arm and middle arm is the cambered surface that radius is 17mm, increased useful flux area, guaranteed that useful flux area meets instructions for use, increased the radiating rate of this FERRITE CORE, and make the dimensional standard of the FERRITE CORE that pulse transformer uses, the amplitude that size is beated reduces, non-standard FERRITE CORE is converted into the FERRITE CORE of standard universal type, the both sides of main body bottom surface are respectively equipped with first protruding block simultaneously, main body bottom surface be provided with second protruding block, the middle part of the second protruding block is provided with groove, the first protruding block end face to the maximum normal distance of main body bottom surface is greater than the second protruding block end face to the maximum normal distance of main body bottom surface, guaranteed that this FERRITE CORE is when sintering, between two these adjacent FERRITE CORE, there is space, and the contact area of two these adjacent FERRITE CORE is less, the air penetrability of the contact area of two these adjacent FERRITE CORE is raise, the surperficial oxygen uptake contacting between two these FERRITE CORE is even, the lumber recovery of product is improved.

Accompanying drawing explanation

In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.

Embodiment

Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.

Below in conjunction with schematic diagram, embodiment of the present utility model is described in further detail.

As depicted in figs. 1 and 2, a kind of novel ferrite magnetic core, comprise main body, the E type that is shaped as of main body, the left arm 11 of main body, the width of right arm 12 and middle arm 13 is 6.5mm, the length of main body is 43.5mm, the height of main body is 26mm, the thickness of main body is 32mm, the left arm 11 of main body, the end face of right arm 12 and middle arm 13 is the cambered surface that radius is 17mm, increased useful flux area, guaranteed that useful flux area meets instructions for use, increased the radiating rate of this FERRITE CORE, and make the dimensional standard of the FERRITE CORE that pulse transformer uses, the amplitude that size is beated reduces, non-standard FERRITE CORE is converted into the FERRITE CORE of standard universal type.

The both sides of main body bottom surface are respectively equipped with first protruding block 14, and the middle part that is provided with second protruding block 15, the second protruding blocks 15 of main body bottom surface is provided with groove 151; The first described protruding block 14 end faces to the maximum normal distance of main body bottom surface is greater than the second protruding block 15 end faces to the maximum normal distance of main body bottom surface, other corners of main body are circular-arc, guaranteed that this FERRITE CORE is when sintering, between two these adjacent FERRITE CORE, there is space, and the contact area of two these adjacent FERRITE CORE is less, the air penetrability of the contact area of two these adjacent FERRITE CORE is raise, the surperficial oxygen uptake contacting between two these FERRITE CORE is even, and the lumber recovery of product is improved.

Be exactly more than a kind of design feature and action effect of novel ferrite magnetic core, its advantage: do not changing under the prerequisite of self material, at volume with highly do not increase in the situation that, useful flux area is being met the demands; During sintering, between product, air penetrability is high, can not occur to deform because ventilative rate variance between product causes, the situation such as cracking, and the surperficial oxygen uptake contacting between product is even, and product lumber recovery is high.

Above-described is only preferred implementation of the present utility model; it should be pointed out that for the person of ordinary skill of the art, do not departing under the prerequisite of the utility model creation design; can also make some distortion and improvement, these all belong to protection range of the present utility model.
