Disk seat is formed by injection molding between every circle circle line of the coil, or the coil is put into existing be adapted
Disk seat in.
The formation of disk seat has two ways, can pass through injection, injection molding between the circle line of coil after the completion of coil is wound
Etc. techniques fill to form integral structure, can also be wound previously according to the disk seat for needing to be made suitable dimension, then by metal plate
At with the matched coil of disk seat size, be directly placed into disk seat, form coil panel.
Preferably, the number of turns of the coil is more than or equal to 2, circle line spacing is equal everywhere.Correspondingly, disk seat the number of turns needs circle
Number is identical as coil, and circle line spacing need to be equal everywhere, to be adapted to coil.
Fourth aspect, the present invention provide a kind of line that the method that technical solution any as described in the third aspect provides obtains
Enclose disk.
Preferably, the disk seat further includes bottom plate, is used to support the coil.
The present invention directly rolls metal plate to form coil, and the circle line thickness of coil is made to be greater than circle line width, this knot
Structure is conducive to improve the magnetic distribution of coil, reduces eddy current effect.

Specific embodiment
In order to make the objectives, technical solutions, and advantages of the present invention clearer, with reference to the accompanying drawings and embodiments, right
The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and
It is not used in the restriction present invention.
It is to be appreciated that directionality instruction is only used for explaining if relating to directionality instruction in the embodiment of the present invention
Relative positional relationship, motion conditions under a certain particular pose between each component etc., if the particular pose changes,
Directionality instruction also correspondingly changes correspondingly.
Embodiment one
Fig. 1 show one piece of rectangle metal plate 1, and L, W, H are respectively its length, by metal plate 1 from short
Start to roll along long side L on one side, until volume is to another short side, form coil 2 as shown in Figure 2, the circle line of coil 2 with a thickness of
The width W of metal plate 1, circle line width are the high H of metal plate 1, and the number of turns of coil 2 is determined by the long side L of metal plate 1.
Because the width W of metal plate 1 is greater than its height H, the coil turn line thickness formed is greater than circle line width.Relative to winding
The coil that formula enamel wire coil and multi-layer PCB coil storehouse are formed, wire coil processing procedure provided by the invention is simple, and coil
It can be more preferable.
It is only illustrated by coil turn line thickness of the short side of metal plate 1 in the present embodiment, in practical application also
May be using long side as coil turn line thickness the case where, that is, forming coil is since the long side of metal plate 1 along W volumes of short side
It rises.Two kinds of situations are present invention technical solution to be protected.
Correspondingly, metal plate 1 is usually rectangle or square, 2 shape of coil formed is well-balanced, magnetic distribution
Uniformly.
Since 1 hardness of metal plate is big, in common embodiment, need that winding cost is assisted to implement using fixture processed
Coil 2 described in example, makes the parameters such as circle line spacing meet pre-provisioning request.
