According to the high-Q-value C-band dielectric resonator, the stability of the medium resonant column on the cavity is improved so as to improve a Q value of the resonator and accordingly the resonator is good in performance and good in vibration and impact resistance.
Description
Technical field
The present invention relates to a kind of high q-factor C-band dielectric resonator.
Background technology
Resonator just refers to the electronic component for producing resonant frequency, and conventional is divided into quartz-crystal resonator and ceramic resonance
Device, plays a part of to produce frequency, with the characteristics of stably, interference free performance is good, is widely used in various electronic products.
Dielectric resonance post in the past in resonator is fairly simple with the fixed structure of chamber mount, is connected using traditional screw
Fixation is connect, easily occurs loosening or dead phenomenon of becoming rusty, easily affect the anti-vibration and impact of resonator, easily reduce resonator
Q-value.
The content of the invention
The technical problem to be solved in the present invention is：Overcome the deficiencies in the prior art, there is provided a kind of high q-factor C-band medium is humorous
Shake device, solves the defect of conventional dielectric resonator and cavity connective stability difference.
The technical solution adopted for the present invention to solve the technical problems is：A kind of high q-factor C-band dielectric resonator, including
Cavity and the dielectric resonance post being arranged on cavity, described dielectric resonance post Jing floor installations on cavity, the medium
The bottom surface Jing binding agents of resonant column are arranged on base, and non-return fastening structure is formed between the base and cavity；
The non-return fastening structure is：Connecting hole is opened up in the middle part of described cavity, is installed in the middle part of the bottom surface of the base
There is connection cylinder, described connection cylinder prolongs its length direction and is provided with cross fluting, is provided with the inwall of the connecting hole
One circle bulge loop, forms the annular groove being engaged with the bulge loop on the outer wall of the connection cylinder；When connection cylinder annular groove and be connected
When bulge loop in hole coordinates, the bottom surface of the base forms veneer with the top surface of cavity and coordinates.
Further, the bottom of the connection cylinder forms one and encloses spigot surface.
Further, female thread is formed with the endoporus of the connection cylinder, described dielectric resonator is also including one
The individual stud being used in combination with endoporus that is being connected cylinder.
The invention has the beneficial effects as follows：Stability of the dielectric resonance post on cavity is improved, and then improves the Q of resonator
Value, so that resonator has better performance, anti-vibration and impact property good.
Description of the drawings
The present invention is further described below in conjunction with the accompanying drawings.
Fig. 1 is the structural representation of this practical dielectric resonator；
Wherein, 1, dielectric resonance post, 2, base, 21, connection cylinder, 3, binding agent, 4, cavity, 41, bulge loop, 5, stud.
Specific embodiment
Presently in connection with accompanying drawing, the present invention is further illustrated.These accompanying drawings are simplified schematic diagram only with signal side
The basic structure of the formula explanation present invention, therefore which only shows the composition relevant with the present invention.
As shown in figure 1, a kind of high q-factor C-band dielectric resonator, including cavity 4 and the medium that is arranged on cavity 4 it is humorous
Shake post 1, and 1 Jing bases 2 of dielectric resonance post are arranged on cavity 4, and the bottom surface Jing binding agent 3 of dielectric resonance post 1 is arranged on base 2
On, non-return fastening structure is formed between base 2 and cavity 4.
The non-return fastening structure is：Connecting hole is opened up in the middle part of cavity 4, connection circle is installed in the middle part of the bottom surface of base 2
Cylinder 21, connection cylinder 21 prolong its length direction and are provided with cross fluting, and the setting of cross fluting can make connection cylinder 21 radially
Possesses certain deformability；A circle bulge loop 41 is provided with the inwall of connecting hole, is connected
The annular groove that bulge loop 41 is engaged；When the bulge loop 41 in the annular groove and connecting hole that connect cylinder 21 coordinates, the bottom surface and chamber of base 2
The top surface of body 4 forms veneer and coordinates.
The bottom of connection cylinder 21 forms one and encloses spigot surface, and a circle spigot surface of the Jing settings can make connection cylinder 21 smooth
Inject in the connecting hole on inner chamber.
Female thread is formed with the endoporus of connection cylinder, dielectric resonator also includes one with the endoporus phase for being connected cylinder
The stud 5 for using cooperatively.Can prevent from connecting inner core generation radial deformation after stud 5 is screwed in connecting hole from bottom,
Can effectively prevent connection inner core from pulling out from connecting hole.
When the dielectric resonance post 1 of the present invention is installed, on base 2, then 1 elder generation Jing binding agents 3 of dielectric resonance post are arranged on
Connection cylinder 21 on Jing bases 2 plugs cooperation with the connecting hole on inner chamber, and by matching somebody with somebody between bulge loop 41 and groove
Conjunction can make Primary Location is formed between base 2 and inner chamber, be then fixed by being selected into 5 pairs of connection cylinders 21 of stud, prevented
Its radial dimension changes and essence connects cylinder 21 and skids off from connecting hole.
With the above-mentioned desirable embodiment according to the present invention as enlightenment, by above-mentioned description, relevant staff is complete
Various change and modification can be carried out in the range of without departing from this invention technological thought entirely.The technology of this invention
Property scope is not limited to the content in description, it is necessary to its technical scope is determined according to right.
