Description
Technical field
The utility model belongs to inductors technique field, and in particular to a kind of inductor core and inductor.
Background technique
Generally to twine inductor of the electric wire as essential structure in magnetic substance, electricity is used in choking-winding, current filter etc.
The field of stream must use.Particularly since there is the limitation of volume to inductor in design, inductor can not be made to become
Greatly, cause DC stacked performance inadequate, or in order to meet the requirement of inductor miniaturization, to use DC stacked have excellent performance
Material.And in order to meet the requirement of the large capacities inductor such as solar power generation, after making hexahedral inductor, as building brick
It forms pillar and equally combines the large-scale inductor of production, since the magnetic core amount used is more, so mainly using less expensive
Iron sial or ferro-silicium series Magnaglo magnetic core.The volume of hexahedron magnetic core is increased, it is just many small without combination
Type magnetic core reduces combination expense, but the molding machine pressure and size that at this time need can sharply increase, need high price at
Type machine has the deformation of magnetic core, or as the increase of height leads to difficult forming, so generally in addition area becomes larger
The hexahedron magnetic core produced is with long 50,60,70,80mm, and wide by 20,30mm, high by 15,20,25mm be specification, so combination
These magnetic cores form the inductor core part in design.
When hexahedron magnetic core is superimposed production inductor, hexahedron magnetic core is selected according to performance requirement, because of six faces
The specification of body magnetic core almost provides in a certain range, so the one of combination of selection.It but because is using
Have the hexahedron magnetic core of specification institution, so if there is lesser performance deficiency needs again plus one layer of magnetic core, or need using
Higher-height magnetic core outside specification, but the consumption that will lead to inductor in this way increases, inductor volume becomes larger, so cannot be very
The good inductor for being applied to fixed specification.
To solve the above-mentioned problems and studied during, finds, in the inductor formed with closed magnetic circuit, with
On the basis of the section of magnetic core, what the magnetic line of force was unevenly distributed, it is more proximate to the inside of closed magnetic circuit, the density of the magnetic line of force is got over
Height, closer to outside, the density of the magnetic line of force is lower.In other words: in the magnetic substance for forming closed magnetic circuit, using basal area as base
Standard, the magnetic saturation of internal magnetic body elder generation become the starting point for hindering inductance, the magnetic substance in outside relative to inside, the magnetic line of force it is close
Spend it is lower, not reach magnetic saturation.But since occurring magnetic saturation for inside, the density of the magnetic line of force is sharply increased, so will be as far as possible
The magnetic saturation of inside is postponed, the current capability of inductor entirety is promoted.
Utility model content
In view of the above technical problems, the purpose of this utility model is to provide a kind of inductor core and inductor, it is used to
It solves the problems, such as to promote inductor overall current performance in the case where not changing inductor core specification.
To achieve the above object, technical solution adopted in the utility model is:
A kind of inductor core mainly constitutes a closed magnetic circuit by yoke portion and stem, it is characterised in that: the stem is from closing
The inside for closing magnetic circuit is incremented by outside magnetic permeability.
Further, the stem is mainly stacked by several magnetic core blocks, the stem from the inside of closed magnetic circuit to
Outside includes layers of magnetic core block.
Further, the stem is multilayered structure from bottom to up, and every layer includes that multiple magnetic core blocks are arranged in array.
Further, the yoke portion is incremented by from the inside of closed magnetic circuit to outside magnetic permeability.
Further, the yoke portion is mainly stacked by several magnetic core blocks, and the yoke portion is multilayer knot from bottom to up
Structure, every layer includes that multiple magnetic core blocks are arranged in array.
Further, the magnetic core block is cuboid.
Further, the inductor core is mainly made of upper yoke portion, lower yoke portion and multiple stems.
Further, the inductor core is mainly made of upper yoke portion, lower yoke portion and two stems.
A kind of inductor, including any of the above-described electric inductor core.
The utility model has the following beneficial effects: the utility model is used to solve the case where not changing inductor core specification
The problem of lower promotion inductor overall current performance.For this purpose, low using the excellent magnetic permeability of current capability in the inside of closed magnetic circuit
Material as magnetic core block, when not needing to expand the volume of inductor core (as being superimposed one layer of magnetic core block or increase magnetic core
Basal area), it can also improve the current capability of inductor.It can minimize, will not additionally increase the basal area of core portion, thus
The electric wire usage amount for being used for kinking is reduced, the expense of kinking is saved, so there is good economic effect.

In figure: 1, upper yoke portion, 2, lower yoke portion, 3, stem, 4, magnetic core block.
Specific embodiment
The utility model in order to better understand does the technical solution of the utility model below with reference to embodiment and attached drawing
Further instruction (as shown in Figure 1, 2).
Embodiment one
A kind of inductor core mainly constitutes a square shape closed magnetic by upper yoke portion 1, lower yoke portion 2 and two stems 3
Road, the upper yoke portion 1, lower yoke portion 2 and stem 3 are incremented by from the inside of closed magnetic circuit to outside magnetic permeability.
The upper yoke portion 1, lower yoke portion 2 and stem 3 are stacked by several magnetic core blocks 4, the upper yoke portion 1, lower yoke portion 2

A kind of inductor, including inductor core described in above-described embodiment one.
The principle of inductor: according to the equal of the section magnetic line of force of the closed magnetic circuit magnetic core of background technique inductor distribution
It is related to the current capability of inductor whether even, the magnetic permeability of inductor core from inside to outside in the application is incremented by, in Fig. 2
The magnetic permeability of magnetic core block a, b, c, d are incremented by successively, when inductor is powered, due to incremental magnetic core block a, b, c, d of magnetic permeability
The magnetic line of force is incremented by, that is, intensive external loose situation inside the existing magnetic core section magnetic line of force is counteracted, so that entire inductor magnetic
The core section magnetic line of force is evenly distributed, and finally improves the current capability of inductor entirety, and without changing original magnetic core, magnetic core
The specification of block 4.
