Abstract

The utility model discloses a kind of c-type magnetic cores, including core body, and the core body is C-shaped, and four arris are equipped with chamfering, and the core body is made of alloy material layer and ferrite layer.Chamfering is arranged in the utility model at four arris of core body, prevents coiling from wearing.

Description

C-type magnetic core

Technical field

The utility model relates to magnetic cores, particularly relate to a kind of c-type magnetic core.

Background technique

The arris of magnetic core is easy to cause coiling to wear without chamfering in the prior art.

Utility model content

The utility model proposes a kind of c-type magnetic cores, and chamfering is arranged at four arris of core body, prevents coiling from grinding Damage.

The technical solution of the utility model is achieved in that

A kind of c-type magnetic core, including core body, the core body is C-shaped, and four arris are equipped with chamfering, described Core body is made of alloy material layer and ferrite layer；The both ends of the core body are equipped with the protrusion of bending, described prominent The portion of rising and the junction of the core body are equipped with groove.

Further, the alloy material layer is permalloy layer or ultracrystallite nano-crystalline layers or Fe-based amorphous layer or cobalt-based Amorphous layer.

Further, the section of the groove is circular arc, and the central angle of the circular arc is greater than 210 °.

The utility model has the beneficial effects that: chamfering is arranged at four arris of core body, prevent coiling from wearing.

Detailed description of the invention

In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only It is some embodiments of the utility model, for those of ordinary skill in the art, in the premise not made the creative labor Under, it is also possible to obtain other drawings based on these drawings.

Fig. 1 is the structural schematic diagram of the utility model c-type magnetic core.

In figure, 1- core body；2- chamfering；3- protrusion；4- groove.

Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without creative efforts Every other embodiment obtained, fall within the protection scope of the utility model.

As shown in Figure 1, the utility model proposes a kind of c-type magnetic core, including core body 1, core body 1 is C-shaped, Its four arris are equipped with chamfering 2, and core body 1 is made of alloy material layer and ferrite layer.

Alloy material layer is permalloy layer or ultracrystallite nano-crystalline layers or Fe-based amorphous layer or cobalt base amorphous layer.

The both ends of core body 1 are equipped with the protrusion 3 of bending, and protrusion 3 and the junction of core body 1 are equipped with groove 4. Protrusion 3 can facilitate magnetic core to be fixed on skeleton.

The section of groove 4 is circular arc, and the central angle of circular arc is greater than 210 °.So set, groove 4 can fix as far as possible around Line.

Chamfering 2 is arranged in the utility model at four arris of core body 1, prevents coiling from wearing.

Above-mentioned technical proposal discloses the improvement of the utility model, the technology contents not being disclosed in detail, can be by this field Technical staff is achieved by the prior art.

The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model Protection scope within.
