Description
Technical field
The present invention relates to technical field of micro communication, relate in particular to a kind of resonatron.
Background technology
Filter is widely used in the communications field as a kind of frequency selection device, especially field of radio frequency communication.In the base station that communication system completion signal transmits and receives, filter is used to select signal of communication, clutter or interference signal that the filtering communication signal frequency is outer.
At present, in mobile communication base station system, the signal that generally uses cavity body filter to come antenna is transmitted and received carries out the frequency selection.Cavity body filter comprises cavity and cover plate, and this cavity is provided with a plurality of cavitys.In each cavity, accommodate a resonatron, said resonatron combines with cavity.
Resonatron is installed on the said cavity through a screw usually, and is contained in the said cavity.Thus, a plurality of cavitys just need a plurality of screws, have not only increased the production cost of said cavity body filter, and have installed the time that said a plurality of screw needs labor, in large batch of production process, can cause production bottleneck, are unfavorable for enhancing productivity.Therefore, industry adopts the mode of welding that said resonatron is installed on the said cavity again.Because resonatron all has ring flange usually, and the space of said cavity is limited, be not easy to welding; Even the not flanged dish of said resonatron after said resonatron is welded in said cavity, solder joint and burr also occur easily, can influence very big to the frequency selectivity of said cavity body filter.
Summary of the invention
In view of this, the present invention provide a kind of low-cost convenient install resonatron.
A kind of resonatron is used to be installed in cavity body filter, and said cavity body filter comprises cavity, and said cavity is provided with erecting bed, and said resonatron comprises body, and said body comprises first end and second end.Said first end forms tuning space to said second concave end; Said second end forms receiving space to said first concave end; On the madial wall of said second end that forms said receiving space, be provided with the line tooth of many said first end to the second extreme directions in edge, said line tooth protrudes on the said madial wall, make said erecting bed be contained in said receiving space after; Form interference fit between said resonatron and the said erecting bed, said body is processed into through header system.
Described resonatron, wherein, said resonatron also comprises flange, said flange combines with the end of said first end away from said second end.
Described resonatron, wherein, said many line teeth are spacedly distributed on the madial wall of said second end.
Described resonatron, wherein, said body is cylinder bodily form strip, and said receiving space is similar with the shape of said body with tuning space.
Described resonatron wherein, is provided with a partition between said receiving space and the tuning space, make between said receiving space and the tuning space not to be communicated with.
Described resonatron, wherein, the quantity of said line tooth is six.
Described resonatron, wherein, said second end is provided with outer chamfering away from the end of said first end.
Through receiving space is set, and said receiving space accommodates the erecting bed on the said cavity on the above-mentioned resonatron, and on the madial wall of the resonatron that forms said receiving space, is provided with many line teeth, makes between said resonatron and the said erecting bed and forms interference fit.Said resonatron need not cooperate with said cavity through extra screw, has not only saved production cost, has saved the time that said screw is installed simultaneously yet.Further, said resonatron is with after said cavity combines, and the solder joint or the burr that occur in the time of can't occurring welding do not influence the frequency selectivity ability of said cavity body filter.
