The RF isolator application of the circuits such as unnecessary radiation is also increasingly wider, makes good use of the effect of isolator, can effectively change
Kind circuit Q.
It is smaller and smaller to the requirement of former device size as communication product integration degree is higher and higher, and with 5G net
The construction of network, customer requirement is integrated planarization, and product working frequency is higher.But outer dimension is small to be meant that
The prototype part of interiors of products is all very small, the permanent magnet of magnetization is played among such circulator because undersized, magnetic field is strong
The frequency range intensity that product needs resonance is not achieved in degree, and then electrical property cannot be achieved in product, can not meet user's requirement.Therefore
We need through new design scheme, under same outer dimension and material condition, product higher frequency are enable to work.
Utility model content
It is above-mentioned to solve the purpose of this utility model is to provide a kind of magnetic conduction sheet of low intermodulation isolator enhancing magnetic flux
The problem of being proposed in background technique.
To achieve the above object, the utility model provides the following technical solutions:
A kind of magnetic conduction sheet of low intermodulation isolator enhancing magnetic flux, including magnetic conduction sheet sheet body, the magnetic conduction sheet sheet body are circle
Shape, the magnetic conduction sheet sheet body circumferencial direction have several integrally formed protrusions.
Further, the quantity of the protrusion is set as three groups, it is adjacent between angle be 120 °.
Further, the protrusion is strip bulge.
Further, the protrusion is semi-cylindrical hill.
Further, the strip bulge length is l, and width d, magnetic conduction sheet sheet body radius is r, and relationship meets as follows
Relationship: r-l=6.29mm, l-d=0.71.
Further, the radius of the semi-cylindrical hill is r1, and magnetic conduction sheet sheet body radius is r, and relationship meets such as ShiShimonoseki
System: r-r1=6.29mm.
Further, the magnetic conduction sheet sheet body circumference surface roughness is 1.6mm.
Compared with prior art, the utility model has the beneficial effects that
The protrusion of magnetic conduction sheet sheet body does not influence magnetic uniformly does not reduce the magnetic conduction sheet of magnetic saturation again, reasonable by selecting
Permeability magnetic material, the magnetic line of force for acting on permanent magnet on gyromagnet are optimal, and active force is maximum, and the magnetic of product then can be enhanced
Saturation degree.
Detailed description of the invention
Fig. 1 is common magnetic conduction sheet structural schematic diagram.
Fig. 2 is 1 magnetic conduction sheet structural schematic diagram of the utility model embodiment.
Fig. 3 is 2 magnetic conduction sheet schematic diagram of the utility model embodiment.
In figure: 1- magnetic conduction sheet sheet body, 2- protrusion.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
In the description of the present invention, it should be noted that term " up/down end ", "inner", "outside" " front end ", " after
The orientation or positional relationship of the instructions such as end ", " both ends ", " one end ", " other end " is that orientation based on the figure or position are closed
System, is merely for convenience of describing the present invention and simplifying the description, rather than the device or element of indication or suggestion meaning are necessary
It with specific orientation, is constructed and operated in a specific orientation, therefore should not be understood as limiting the present invention.In addition,
Term " first ", " second " are used for descriptive purposes only and cannot be understood as indicating or suggesting relative importance.
In the description of the present invention, it should be noted that unless otherwise clearly defined and limited, term " is pacified
Dress ", " be arranged/be arranged with ", " socket ", " connection " etc., shall be understood in a broad sense, such as " connection ", may be a fixed connection, can also
To be to be detachably connected, or be integrally connected；It can be mechanical connection, be also possible to be electrically connected；It can be directly connected, it can also
Indirectly connected through an intermediary, can be the connection inside two elements.For the ordinary skill in the art,
The concrete meaning of above-mentioned term in the present invention can be understood with concrete condition.
Common magnetic conduction sheet is as shown in Figure 1, since the special-shaped lug boss 3 of magnetic conduction sheet sheet body 1 itself is in irregular shape at present；?
It has to make to act on the magnetic line of force on gyromagnet with magnetic conduction sheet (i.e. magnetic conduction sheet sheet body 1) uniform among permanent magnet and gyromagnet, reaches
The smallest purpose is lost to product, and since the difference of current magnetic conduction sheet radius and special-shaped lug boss 3 is less than 0.6 (mm), and lead
Magnetic sheet will lead to the intensity of magnetization mostly in intermediate isolation and reduce.
