Abstract
This application discloses a kind of isolated lattice coils, for small reactor, it includes the first copper coil, insulating layer and the second copper coil, the insulating layer is arranged between first copper coil and second copper coil, the insulating layer is low-k insulating layer, and the thickness of the insulating layer and the thickness of first copper coil and second copper coil are consistent.The isolated lattice coil for being used for small reactor increases interfloor distance and increasing insulating layer in coil interlayer and reduces interlayer dielectric coefficient, quality factor is improved, so that the cost of small reactor is not significantly increased.
Description
Technical field
This application involves magnetic element more particularly to a kind of isolated lattice coils for small reactor.
Background technique
For small reactor, quality factor Q value is extremely important, it can reflect the ratio of impedance and D.C. resistance
Value, is considered as an important parameter of reactor.In the exploitation biggish small reactor product of quality factor, it is desirable that coil layer
Between interlayer dielectric coefficient reduce, but the small volume of present lattice coil, the interlayer spacing between coil and coil is smaller,
Cause interlayer dielectric coefficient excessive, the i.e. direct current of the small reactor smaller so as to cause the quality factor of small reactor
Hinder larger, this can be such that the cost of small reactor is significantly increased.
Utility model content
The application provides a kind of novel isolated lattice coil.
According to a first aspect of the present application, the application provides a kind of isolated lattice coil, is used for small reactor, packet
The first copper coil, insulating layer and the second copper coil are included, the insulating layer is arranged in first copper coil and second copper wire
Between circle, the insulating layer is low-k insulating layer, the thickness of the insulating layer and first copper coil and described the
The thickness of two copper coils is consistent.
Preferably, after the insulating layer expansion, the both ends of the insulating layer are respectively arranged with the first weld access hole and second
Weld access hole, is provided with the first solder joint corresponding with first weld access hole on the inside of first copper coil, and described
The second solder joint corresponding with second weld access hole is provided on the inside of two copper coils.
Preferably, it will be bonded between first copper coil, insulating layer and the second copper coil by Instant cement.
Preferably, first copper coil passes through high temperature gummed tape with second copper coil respectively and is coated.
Preferably, after the insulating layer expansion, two long sides of the insulating layer have a degree of interior receipts.
The beneficial effect of the application is: this is used for the isolated lattice coil of small reactor by increasing in coil interlayer
Insulating layer and increase interfloor distance and reduce interlayer dielectric coefficient, improve quality factor so that small reactor at
This is not significantly increased.
Detailed description of the invention
Fig. 1 is the side view of the isolated lattice coil in one embodiment of the application；
Fig. 2 is the structural schematic diagram after the insulating layer expansion in Fig. 1.
Specific embodiment
The application is described in further detail below by specific embodiment combination attached drawing.
As shown in Figure 1, the isolated lattice coil mainly uses the utility model discloses a kind of isolated lattice coil
In small reactor, refering to fig. 1, which includes the first copper coil 1, insulating layer 2 and the second copper coil 3,
The insulating layer is arranged between first copper coil 1 and second copper coil 3, and the insulating layer is mainly used for increasing
The interfloor distance and reduction interlayer dielectric coefficient of coil；The insulating layer 2 is low-k insulating layer, the insulating layer 2
Thickness can be determined according to actual needs, it is preferred that the thickness of the insulating layer 2 and first copper coil 1 and second bronze medal
The thickness of coil 3 is consistent.
As shown in Fig. 2, the both ends of the insulating layer 2 are respectively arranged with the first weld access hole 21 after the insulating layer 2 is unfolded
With the second weld access hole 22, the inside of first copper coil 1 is provided with and first weld access hole 21 corresponding first
Solder joint, the inside of second copper coil 3 are provided with second solder joint corresponding with second weld access hole 22, specific implementation
When, first the first copper coil 1, insulating layer 2 and the second copper coil 3 are bonded using Instant cement by tool fixture, then reused
First solder joint and the second solder joint are respectively welded filamentary silver, finally also can be used high temperature gummed tape by first copper coil 1 with it is described
Second copper coil 3 is respectively coated by.
Referring again to Fig. 2, the insulating layer 2 be unfolded after the not conventional rectangle of shape, by two long sides of rectangle
A degree of interior receipts are carried out, so that the region area of the correspondence solder joint of insulating layer is respectively greater than the first solder joint and the second weldering
The area of point reduces the production difficulty of product so that the reliability of welding improves.
It should be noted that the number of plies of the isolated lattice coil in the present embodiment only has 2+1 layers, but it is not excluded for the isolation
The number of plies of formula lattice coil can be 3+2,4+3 or n+ (n-1) layer.Specific number of plies design will refer to the isolated lattice coil
Product demand.
The isolated lattice coil for being used for small reactor increases interlamellar spacing and increasing insulating layer in coil interlayer
From with reduce interlayer dielectric coefficient, quality factor are improved, so that the cost of small reactor is not significantly increased.
The foregoing is a further detailed description of the present application in conjunction with specific implementation manners, and it cannot be said that this Shen
Specific implementation please is only limited to these instructions.For those of ordinary skill in the art to which this application belongs, it is not taking off
Under the premise of from the design of the application utility model, a number of simple deductions or replacements can also be made.
