The stability of the dielectric resonance column on the cavity is improved, so the Q value of the resonator is increased, and the resonator has better performance and good shock and impact resistance.
Description
Technical field
The present invention relates to a kind of high q-factor KU wave band dielectric resonator.
Background technology
Resonator just refers to the electronic component producing resonance frequency, and conventional is divided into quartz-crystal resonator and ceramic resonator, plays a part to produce frequency, has stable, the feature that interference free performance is good, is widely used in various electronic product.
Dielectric resonance post in the past in resonator and the fixed structure of chamber mount fairly simple, adopt traditional screw to be connected and fixed, easily occur loosening or dead phenomenon of becoming rusty, very easily affect anti-vibration and the impact of resonator, easily reduce the Q value of resonator.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the deficiencies in the prior art, provides high q-factor KU wave band dielectric resonator.
The technical solution adopted for the present invention to solve the technical problems is: a kind of high q-factor KU wave band dielectric resonator, comprises dielectric resonance post, base and cavity, and described dielectric resonance post is arranged on cavity upper end through base;
Described base comprises base plate and is arranged on the column in the middle of base plate, and be provided with bolt hole in the middle part of column, bolt hole runs through column and base plate, and base is fixed on cavity through bolt passing through bolt hole; Arrange the installing hole run through up and down in the middle part of described dielectric resonance post, in the bottom radial direction of installing hole, convex into mounting panel, the distance of mounting panel distance dielectric resonance post bottom is less than the height of column, and dielectric resonance post is fixed on base through mounting panel by bolt; Annular groove on some circles is formed in the upper surface of base plate, the bottom face of described dielectric resonance post is formed the lower annular groove of some that correspond, upper annular groove and lower annular groove measure-alike, yielding rubber circle is respectively arranged with on each in annular groove, the diameter of described yielding rubber circle is slightly larger than the diameter of annular groove, and described dielectric resonance post forms resilient engagement through yielding rubber circle and base plate.
Further, the sidewall of described column is coated with adhesive, and the sidewall of described column is connected with the installing hole inwall of dielectric resonance post through adhesive.
The invention has the beneficial effects as follows: change the syndeton between traditional sucrose resonant column and cavity, improve the stability of dielectric resonance post on cavity, and then improve the Q value of resonator, thus make resonator have better performance, anti-vibration and impact property good.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the present invention is further described.

Wherein, 1, cavity, 2, base, 21, base plate, 22, column, 3, dielectric resonance post, 31, mounting panel, 4, bolt, 5, yielding rubber circle, 6, adhesive.
Embodiment
The present invention is further illustrated by reference to the accompanying drawings now.The schematic diagram that these accompanying drawings are simplification only illustrates basic structure of the present invention in a schematic way, and therefore it only shows the formation relevant with the present invention.
As shown in Figure 1, a kind of high q-factor KU wave band dielectric resonator, comprises dielectric resonance post 3, base 2 and cavity 1, and dielectric resonance post 3 is arranged on cavity 1 upper end through base 2.
Base 2 comprises base plate 21 and is arranged on the column 22 in the middle of base plate 21, base plate 21 and column 22 are structure as a whole, be provided with bolt hole in the middle part of column 22, bolt hole runs through column 22 and base plate 21, and base 2 is fixed on cavity 1 through bolt 4 through bolt hole; The installing hole run through up and down is set in the middle part of dielectric resonance post 3, mounting panel 31 is convexed in the bottom radial direction of installing hole, mounting panel 31 is less than the height of column 22 apart from the distance of dielectric resonance post 3 bottom, and dielectric resonance post 3 is fixed on base 2 through mounting panel 31 by bolt 4; Annular groove on some circles is formed in the upper surface of base plate 21, the bottom face of dielectric resonance post 3 is formed the lower annular groove of some that correspond, upper annular groove and lower annular groove measure-alike, yielding rubber circle 5 is respectively arranged with on each in annular groove, the diameter of yielding rubber circle 5 is slightly larger than the diameter of annular groove, and dielectric resonance post 3 forms resilient engagement through yielding rubber circle 5 and base plate 21.When the diameter why diameter of yielding rubber circle 5 is greater than annular groove is to make the mounting panel 31 of dielectric resonance post 3 on the column 22 being pressed in base 2, dielectric resonance post 3 and base 2 leave the space of certain damping.
The sidewall of column 22 is coated with adhesive 6, and the sidewall of column 22 is connected with the installing hole inwall of dielectric resonance post 3 through adhesive 6.The space between column 22 sidewall and dielectric resonance post 3 filled by adhesive 6, and when the phenomenon loosened appears in stud, adhesive 6 can limit the displacement of dielectric resonance post 3, improves the shock resistance of dielectric resonance post 3 of the present invention further.
Adopt dielectric resonance post 3 of the present invention, dielectric resonance post 3 is when being pressed on base 2, certain space can be left between the bottom surface of dielectric resonance post 3 and base plate 21, this space is the space required when being crushed out of shape of yielding rubber circle 5, the stability of dielectric resonance post 3 is improved through yielding rubber circle 5, improve the Q value of resonator, thus make resonator have better performance, anti-vibration and impact property good.
