Coaxial resonant cavity belongs to a unit of microwave coaxial filter or oscillator, and it is applied in the repeater and base station of moving communicating field.Duplexer in the special base station, the filter of mixer requires coaxial resonant cavity to have small size, and is high-power, high features such as product prime number.Inner wire be coaxial resonant cavity main components, the key property of inner wire comprises quality factor (Q value), high power capacities etc., inner wire are that coaxial resonant cavity realizes bearing powerful critical piece.It is less that coaxial resonant cavity generally requires housing depth now, and traditional method is to make " T " font being located in the cavity inner wire, adopts single capacitive load, causes coaxial resonant cavity to be difficult to bear high-power.
The utility model content
The utility model is in order to solve existing coaxial resonant cavity, to be difficult to realize powerful problem, provides a kind of inner wire of big pulse peak power that the coaxial resonant cavity of step is arranged.
For addressing the above problem, the technical solution of the utility model is the coaxial resonant cavity that a kind of inner wire of structure has step, comprise a cavity, be located at the inner wire in the cavity, inner wire comprises a stepped cylinder type mobile jib, is located at the annular flat board on this cylinder type mobile jib top, and the annular shirt rim that folding forms under the annular top panel lateral margin, cylinder type mobile jib, annular top panel, annular shirt rim are coaxial one-body molded.
Wherein, described cylinder type mobile jib is made up of the multistage tubular cylinder, and each section tubular cylinder is coaxial successively to link to each other, and the two neighboring sections tubular cylinder is less near the diameter of cavity bottom.
The inside and outside wall of described cylinder type mobile jib outside wall surface all stepped or the cylinder type mobile jib is stepped.
Described cylinder type mobile jib is made up of two sections tubular cylinder.
Described cylinder type mobile jib is made up of three sections tubular cylinder.
Described annular top panel is provided with at least one through hole.
Described cavity is provided with a tuning screw rod that inserts in the cylinder type mobile jib chamber.
Described cavity and inner wire are metal material, but its surface metal cladding.
The utility model realizes that by inner wire four partition capacitances load, one, the inner wire annular is dull and stereotyped and the cavity top cover between capacity plate antenna; Two, the annular shirt rim of inner wire and the edge capacitance between cavity wall; Three, face the turning electric capacity that forms between the tubular cylinder on the inner conductor cylinder type mobile jib mutually.Four, the cylinder electric capacity of inner wire and tuning screw rod formation.Compared with prior art the utility model by adjusting the loading capacitance amount between cavity and the inner wire, is offered through hole 5 and can be improved power capacity on the annular flat board 3.
Description of drawings
Below in conjunction with drawings and Examples the utility model is described further, wherein:
Fig. 1 is the utility model first embodiment vertical view;
Fig. 2 is Fig. 2 A-A cutaway view;
Fig. 3 is the utility model first embodiment inner wire schematic perspective view;
Fig. 4 is the utility model second embodiment vertical view;

Embodiment
Shown in Fig. 2,5, this figure is the basic structure of the utility model preferred embodiment, a kind of inner wire has the coaxial resonant cavity of step, comprise sealable cavity 1, be located at the inner wire 2 in the cavity 1, (with reference to Fig. 3) inner wire 2 comprises a stepped cylinder type mobile jib, is located at the annular flat board 3 on this cylinder type mobile jib top, and dull and stereotyped 3 lateral margins of the annular annular shirt rim 4 that forms of folding down.Cylinder type mobile jib top is run through annular dull and stereotyped 3 and is connected with it, and the cylinder type mobile jib other end is connected with a cavity 1 inner bottom surface.Be furnished with at least one small through hole 5 on the annular top panel 3.The coaxial one machine-shaping of inner wire 2 each several parts, cavity 1 is a metal material with inner wire 2 manufacturing materials, for example selects the brass processing and fabricating for use, but its surface metal cladding.Can not there be slide mark on inner wire 2 surfaces after inner wire 2 was made and finished.As shown in Figure 2, inner wire 2 is vertical at the bottom center of cavity 1, and fixes by screw.On the top board 12 of cavity 1, be provided with the tuning screw rod 6 in the cylinder type mobile jib inner chamber that inserts inner wire 2.
Shown in Fig. 2,5, the cylinder type mobile jib is made up of multistage tubular cylinder 01, and described each section tubular cylinder 01 is coaxial successively to link to each other, and two neighboring sections tubular cylinder 01 is less near the diameter of cavity 1 bottom, becomes stepped after each section tubular cylinder 01 links to each other successively.Adjacent tubular cylinder 01 is because the difference in size of diameter can form turning electric capacity behind loading capacitance, adjacent tubular cylinder 01 diameter difference is big more, and its turning electric capacity is big more.The inside and outside wall of cylinder type mobile jib is all stepped, also can have only the outside wall surface of cylinder type mobile jib stepped, and internal face is an even surface.
Among first embodiment, the cylinder type mobile jib of (with reference to Fig. 1, Fig. 2) inner wire 2 is made up of two sections tubular cylinder 7,8, and the inside and outside wall of cylinder type mobile jib all becomes stepped, is evenly equipped with six through holes 5 on the annular top panel 3.
Among second embodiment, the cylinder type mobile jib of (with reference to Fig. 4, Fig. 5) inner wire 2 is made up of three sections tubular cylinder 9,10,11, and the inside and outside wall of cylinder type mobile jib all becomes stepped, is evenly equipped with six through holes 5 on the annular top panel 3.
The utility model adopts by four partition capacitances to load, and one is that header-terminal capacitance loads, the annular of inner wire 2 dull and stereotyped 3 and 12 capacity plate antennas of cavity 1 top cover, and annular dull and stereotyped 3 is big more with the more little electric capacity of cavity top cover 12 spacings; The 2nd, edge capacitance, the annular shirt rim 4 of inner wire 2 down extends longly more, and is big more with the more little electric capacity of spacing of cavity 1 sidewall; The 3rd, turning electric capacity; The 4th, the cylinder electric capacity that inner wire 2 and tuning screw rod 6 constitute, tuning screw rod 6 inserts in the cylinder type mobile jib chambeies dark more, and electric capacity is big more.Offer through hole 5 on the annular top panel 3 and can improve power capacity.
Compared with prior art, when the housing depth of coaxial resonant cavity requires hour, when simultaneously requirement can be born very big pulse peak power again, the utility model can carry out reasonable distribution by adjusting above-mentioned four kinds of electric capacity, and punch on the annular top panel, make resonator have bigger power capacity.The utility model, inner wire Q value is high, effectively improves the power capacity of coaxial resonant cavity, and makes it have good temperature characterisitic.
