Winding wire is absorbed in the groove portion, and the annular component is permeability magnetic material component.
As a further improvement of the above technical scheme, the annular component is silicon steel component, the bottom surface and the ring
Shape component is bonded, and the bottom surface is magnetic conduction insulating component.
As a further improvement of the above technical scheme, the annular component is further segmented as several independent arcuation structures
Part.
As a further improvement of the above technical scheme, the magnetic conduction insulating component is rubber magnet component.
As a further improvement of the above technical scheme, the winding wire includes the first winding wire and the second winding wire, institute
State the first winding wire line footpath be less than the second winding wire, first winding wire and the second winding wire side by side, described first and second around
The head of group line is connected, and the tail portion of first and second winding wire is connected.
As a further improvement of the above technical scheme, the head, tail portion connecting place are equipped with wicking.
The beneficial effects of the invention are as follows：A kind of lattice coil is provided, using annular component made of permeability magnetic material as line
Iron core is enclosed, the inductance value of coil is improved, correspondingly reduces the number of turn of coil, reduce winding volume.

Specific embodiment
The technique effect of the design of the present invention, concrete structure and generation is carried out below with reference to embodiment and attached drawing clear
Chu, complete description, to be completely understood by the purpose of the present invention, feature and effect.Obviously, described embodiment is this hair
Bright part of the embodiment rather than whole embodiments, based on the embodiment of the present invention, those skilled in the art is not paying
The other embodiment obtained under the premise of creative work, belongs to the scope of protection of the invention.In addition, be previously mentioned in text
All connection/connection relations not singly refer to component and directly connect, and refer to be added deduct by adding according to specific implementation situation
Few couple auxiliary, to form more preferably coupling structure.Every technical characteristic in the invention, in not conflicting conflict
Under the premise of can be with combination of interactions.
Embodiment 1, with reference to figure 1, a kind of lattice coil, bottom surface 1, winding wire 2 and several annular components 3 including sheet,
Wherein winding wire 2 is using the enameled wire of heating self-adhesion, and so-called enameled wire is a principal item of winding wire, by bare wire and insulation
Two composition of layer after the annealed softening of bare wire, using multiple japanning, bake.With reference to figure 3, the winding wire 2 is by two
Winding wire is formed, and is the first winding wire a1 and the second winding wire a2 respectively, wherein the diameter of the second winding wire a2 be more than first around
Side by side, first and second winding wire a1, a2 heads are connected, first and second winding wire a1, a2 tail by group line a1, first and second winding wire a1, a2
Portion is connected, and the winding cable architecture of small one and large one line footpath in this way can reduce the distribution capacity between coil turn and circle, improves coil
Quality factor.As an optimization, wicking is equipped on the head of first and second winding wire a1, a2 and tail portion, coil is facilitated to weld.
The annular component 3 forms concentric arry and is bonded with bottom surface 1 by resin glue or integrally change structure,
4 are formed a groove between the annular component 3, the winding wire 2 is absorbed in the groove portion 4, and the annular component 3 is permeability magnetic material structure
Part.
The structure of this lattice coil, since the magnetic resistance of annular component 3 is very low so that annular component 3 can incite somebody to action a large amount of
The magnetic line of force is put together, and is reduced the outer of the magnetic line of force and is dissipated, the density of line of magnetic force in increase actual induction area, before exciting current is constant
It puts, promotes inductance value.Because of annular component 3 as auxiliary, therefore under identical inductance value, accordingly reduce coil
The number of turn, reduce the volume of coil.
As an optimization, bottom surface 1 and annular component 3 are bonded with resin glue, annular component 3 is set as silicon steel component, it will
Bottom surface 1 is set as magnetic conduction insulating component, and the present embodiment uses rubber magnet component.So, between several annular components 3 magnetic conduction but
It is insulation, reduces the eddy-current loss of coil at work.
With reference to figure 2, in order to be further reduced eddy-current loss, as an optimization, annular component 3 is divided into several independent arcs
Shape component 31.
The better embodiment of the present invention is illustrated, but the invention is not limited to the implementation above
Example, those skilled in the art can also make various equivalent modifications under the premise of without prejudice to spirit of the invention or replace
It changes, these equivalent modifications or replacement are all contained in the application claim limited range.
