Abstract
The utility model discloses a kind of iron-core coil, including winding wire and iron core, the winding wire surrounds the iron core, the iron core includes some ring-type iron cores, it is socketed between ring-type iron core, gap is provided between the adjacent ring-type iron core, the gap is full of insulating materials component, and the ring-type iron core is metal magnetic conducting material members.Some ring-type iron cores are made of metal magnetic conducting material, and they are socketed the existing cylinder iron core of replacement, and separated between ring-type iron core by insulator, the contradiction between magnetic hystersis loss and eddy-current loss is solved by such structure, the iron loss of iron-core coil is reduced.
Description
Technical field
The utility model is related to a kind of coil, more particularly to a kind of iron-core coil.
Background technology
Existing iron-core coil is cylinder iron core, and winding wire surrounds along the outer surface of cylinder, and this coil can be with
Accomplish very big inductance value.Although the inductance value of iron-core coil can accomplish very big, inductance value is bigger, and its iron loss is bigger.
So-called iron loss includes magnetic hystersis loss and eddy-current loss.The silicon steel sheet of high magnetic conduction can be used by reducing magnetic hystersis loss, but so but
Eddy-current loss can not be reduced, if non-metallic isolator is used to reduce eddy-current loss as iron core, due to nonmetallic exhausted
The magnetic conductivity of edge is not universal high, therefore so eddy-current loss is reduction of, but magnetic hystersis loss is but improved.In order to solve
This contradiction, inventor provides a kind of iron-core coil of low iron loss.
Utility model content
The technical problems to be solved in the utility model is：Solve the lance between iron-core coil eddy-current loss and magnetic hystersis loss
Shield.
The solution that the utility model solves its technical problem is：A kind of iron-core coil, including winding wire and iron core, institute
Winding wire is stated around the iron core, the iron core includes being socketed between some ring-type iron cores, ring-type iron core, the adjacent ring-type
Gap is provided between iron core, the gap is full of insulating materials component, and the ring-type iron core is metal magnetic conducting material members.
As the further of such scheme, the insulating materials component is rubber magnet component.
As the further of such scheme, the ring-type iron core is silicon steel component.
As the further of such scheme, the winding wire include the first winding wire and the second winding wire, described first around
The line footpath of group line is less than the second winding wire, the head of first winding wire and the head connection of the second winding wire, described first
The afterbody connection of the afterbody of winding wire and the second winding wire.
It is used as the further of such scheme, the outer surface coating insulation heating self-adhesion paint of first and second winding wire.
The beneficial effects of the utility model are：Some ring-type iron cores are made of metal magnetic conducting material, and their sets are taken over
Separated for existing cylinder iron core, and between ring-type iron core by insulator, solving magnetic hysteresis by such structure damages
Contradiction between consumption and eddy-current loss, reduces the iron loss of iron-core coil.
Brief description of the drawings
, below will be to needed for embodiment description in order to illustrate more clearly of the technical scheme in the utility model embodiment
The accompanying drawing to be used is briefly described.Obviously, described accompanying drawing is a part of embodiment of the present utility model, rather than entirely
Portion's embodiment, those skilled in the art on the premise of not paying creative work, can also obtain it according to these accompanying drawings
His design and accompanying drawing.
Fig. 1 is the structural representation of iron-core coil；
Fig. 2 is the structural representation of winding wire.
Embodiment
The technique effect of design of the present utility model, concrete structure and generation is carried out below with reference to embodiment and accompanying drawing
Clearly and completely describe, to be completely understood by the purpose of this utility model, feature and effect.Obviously, described embodiment
It is a part of embodiment of the present utility model, rather than whole embodiments, based on embodiment of the present utility model, the skill of this area
The other embodiment that art personnel are obtained on the premise of not paying creative work, belongs to the model of the utility model protection
Enclose.In addition, all connection/annexations being previously mentioned in text, not singly refer to component and directly connect, and refer to can be according to specific reality
Situation is applied, by adding or reducing couple auxiliary, to constitute more excellent draw bail.Each technology in the invention is special
Levy, can be with combination of interactions on the premise of not conflicting conflict.
Embodiment 1, with reference to Fig. 1, a kind of iron-core coil, its iron core is socketed to form by 3 ring-type iron cores, from outside to inside successively
For：Gap is provided between first iron core t1, the second iron core t2 and the 3rd iron core t3, first, second and third iron core t1, t2, t3, it is described
Gap fill insulant component, the ring-type iron core is metal magnetic conducting material members.Winding wire is outer along the first iron core t1's
Side face is surrounded by coil.
By such structure, iron core point is socketed to form by 3 ring-type iron cores, and between this 3 ring-type iron cores
And it is non-conductive, on the premise of the good convergence magnetic line of force is ensured, the vortex formed on iron core is reduced, eddy-current loss is reduced.
As optimization, in the gap filled rubber magnetic component.Rubber magnet has two kinds of properties of magnetic conduction and insulation, is ensureing
On the premise of being insulated between ring-type iron core, magnetic resistance is reduced, the quality factor of coil are lifted.Further, by first, second and third iron core
T1, t2, t3 are set to silicon steel component.
As optimization, with reference to Fig. 2, the winding wire includes the first winding wire a1 and the second winding wire a2, described first around
Group line a1 line footpath is less than the second winding wire a2, the first winding wire a1 head and the second winding wire a2 head connection,
The afterbody connection of the afterbody and the second winding wire a2 of the first winding wire a1.Winding wire by the use of small one and large one line footpath is used as line
Coiling is enclosed, by the difference of two lines internal resistance, the potential difference between coil turn and circle is reduced, so as to reduce the distribution electricity of coil
Hold.
It is used as optimization, the outer surface coating epoxy resin of first and second winding wire.Be conducive to the insulation between winding wire
And heating bonding so that coil is difficult loosely.
Better embodiment of the present utility model is illustrated above, but the invention be not limited to it is described
Embodiment, those skilled in the art can also make a variety of equivalent changes on the premise of without prejudice to the utility model spirit
Type or replacement, these equivalent modifications or replacement are all contained in the application claim limited range.
