Description
Technical field
The utility model relates to communication technical field, relates in particular to resonatron and uses the cavity body filter of this resonatron.
Background technology
Filter is widely used in the communications field as a kind of frequency selection device, especially field of radio frequency communication.Finish in the base station that signal transmits and receives in communication system, 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 generally includes cavity, and the chamber is risen and is provided with a plurality of cavitys, contains resonatron in each cavity.In the cavity body filter large-scale production, need large batch of resonatron.Traditional resonatron all processes by turning, and well-known, turning need expend a large amount of time, and comprises resonant cavity in the resonatron, uses the monoblock material to process resonatron, can cause the waste of lot of materials.Therefore, in the large-scale production process, use turning processing resonatron to be unfavorable for providing efficiency, reduce production costs.
The utility model content
In view of this, the utility model provides a kind of stretching resonatron of being convenient to large-scale production.
In addition, also be necessary to provide a kind of cavity body filter that uses above-mentioned stretching resonatron.
A kind of resonatron comprises ring flange, cylinder, described ring flange is arranged at an end of described cylinder, and this resonatron also comprises positioning table and through hole, and described positioning table is arranged at the other end of described cylinder, described through hole is arranged at the end face of described positioning table, and described resonatron is formed by stretching.
In the above-mentioned resonatron, described cylinder is the cylinder bodily form, and inside is hollow form.
In the above-mentioned resonatron, described positioning table is the cylinder bodily form, and inside is hollow form, and described cylinder is coaxial with described positioning table, and described positioning table radius perpendicular to axial direction is less than described cylinder radius perpendicular to axial direction.
A kind of cavity body filter that uses above-mentioned resonatron, this cavity body filter comprises cavity, supporting seat, resonatron, described resonatron comprises ring flange, cylinder, positioning table and through hole, described ring flange is arranged at an end of described cylinder, described positioning table is arranged at the other end of described cylinder, described through hole is arranged at the end face of described positioning table, and described resonatron is formed by stretching.
In the above-mentioned cavity body filter, described supporting seat and described cavity are one-body molded, and described supporting seat and described cavity form by die casting.
In the above-mentioned cavity body filter, described resonatron passes through a screw on described supporting seat.
In the above-mentioned cavity body filter, described positioning table is the cylinder bodily form, and inside is hollow form, and described cylinder is coaxial with described positioning table, and described positioning table radius perpendicular to axial direction is less than described cylinder radius perpendicular to axial direction.
Resonatron related in above-mentioned resonatron, the cavity body filter all processes by stretching mode, and it adopts the turning mode to process with respect to tradition, owing to do not need turning to remove conductor material, its cost reduces greatly; Simultaneously, because the stretch process mode saves time than the turning processing mode, the resonatron quantity of processing is more in the unit interval, has improved efficiency, is convenient to batch, large-scale production.
