Background technique

The sintering magnetic metal oxide that magnetic core is made of various iron oxide mixtures, in the prior art, ferrite magnetic Core is in the coil and transformer of various electronic equipments.For example, manganese-zinc ferrite is typical magnetic core array material, and there is height The characteristics of magnetic conductivity and high magnetic flux density, has more low-loss characteristic when being lower than the frequency of 1MHz.The material and knot of magnetic core Structure is an important factor for influencing magnetic core performance.In the prior art, single center pillar is arranged in magnetic core more, when needing multiple groups coil, needs It to use multiple groups magnetic core to cooperate, take up space big.

Utility model content

The purpose of this utility model is to provide a kind of distele magnetic cores, to overcome deficiency in the prior art.

To achieve the above object, the utility model provides the following technical solutions:

The embodiment of the present application discloses a kind of distele magnetic core, including integrally formed bottom plate, is symmetrically disposed on the bottom Two side columns of board ends, the two side columns insides are respectively provided with a center pillar, and the bottom plate is rectangular configuration, two sides The equivalent width of column length and the bottom plate, two center pillars are cylindrical-shaped structure, two side column inner side end centers difference It is recessed with cambered surface groove, the groove is coaxially disposed with the corresponding center pillar, and the minimum range between two center pillars is described Twice to respective slot minimum range of center pillar.

Preferably, in above-mentioned distele magnetic core, the groove is round with the junction of the corresponding side column inner side end It slips over and crosses.

Preferably, in above-mentioned distele magnetic core, the bottom plate two sides are recessed with set corresponding with two center pillars respectively The two pairs of V-shaped grooves set.

Preferably, in above-mentioned distele magnetic core, the V-shaped groove opening and the round and smooth mistake in bottom panel side junction It crosses.

Preferably, in above-mentioned distele magnetic core, the base angle of the V-shaped groove is globoidal structure.

Compared with the prior art, the advantages of the utility model are: described in the utility model fill for new-energy automobile The core structure of electric stake is simple, can assemble two groups of coils simultaneously, reduces the overall volume of transformer or charging equipment, can also subtract The use of few magnetic material.

Detailed description of the invention

In order to illustrate the technical solutions in the embodiments of the present application or in the prior art more clearly, to embodiment or will show below There is attached drawing needed in technical description to be briefly described, it should be apparent that, the accompanying drawings in the following description is only this The some embodiments recorded in application, for those of ordinary skill in the art, without creative efforts, It is also possible to obtain other drawings based on these drawings.

Fig. 1 show the structural schematic diagram of distele magnetic core in the utility model specific embodiment.

Fig. 2 show the bottom view of distele magnetic core in the utility model specific embodiment.

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 Detailed description, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole implementation Example.Based on the embodiments of the present invention, those of ordinary skill in the art institute without making creative work The every other embodiment obtained, fall within the protection scope of the utility model.

Join shown in Fig. 1 and Fig. 2, a kind of distele magnetic core, including integrally formed bottom plate 10, is symmetrically disposed on 10 liang of bottom plate Two side columns 20 at end, a center pillar 30 is respectively provided on the inside of two side columns 20, and bottom plate 10 is rectangular configuration, two side columns, 20 length With the equivalent width of bottom plate 10, two center pillars 30 are cylindrical-shaped structure, and it is recessed that two side columns, 20 inner side end center is recessed with cambered surface respectively Slot 21, groove 21 are coaxially disposed with corresponding center pillar 30, and the minimum range between two center pillars 30 is that center pillar 30 arrives respective slot 21 most Twice of small distance.

In the technical solution, the core structure described in the utility model for new-energy automobile charging pile is simple, can be same When assemble two groups of coils, reduce the overall volume of transformer or charging equipment, the use of magnetic material, two center pillars can also be reduced Between minimum range be center pillar to twice of respective slot minimum range, it is preferable that the minimum range between two center pillars is in Column diameter is identical, and the minimum range of center pillar to respective slot and the radius of center pillar are identical, and two center pillars can be arranged or diffraction is identical Coil, and will not interfere.

Further, the junction rounding off of groove 21 and corresponding 20 inner side end of side column.

In the technical solution, the junction rounding off of groove and corresponding side column inner side end, when use, will not be to coiling It causes to damage.

Further, 10 two sides of bottom plate are recessed with two pairs of V-shaped grooves 11 being correspondingly arranged with two center pillars 30 respectively.

In the technical solution, bottom plate two sides are recessed with two pairs of V-shaped grooves being correspondingly arranged with two center pillars respectively, can be convenient magnetic The positioning and fixation of core, while being conducive to the heat dissipation of magnetic core.

Further, the opening of V-shaped groove 11 and 10 side junction rounding off of bottom plate.

Further, the base angle of V-shaped groove is globoidal structure.
