Abstract
The present invention relates to a kind of adjustable cavity body filter, belong to wireless communications application field, including housing, tuning screw, housing is cavity structure, tuning screw pass housing side, it is characterised in that described wave filter also include can reduction regulation harmonic oscillator, harmonic oscillator is arranged on the corresponding side housing exterior walls of tuning screw, and on outer wall, having screw, harmonic oscillator is cylindrical, and its one end has cylindrical cavity, the other end has screw thread, and thread head connection has cylindrical big end.The adjustable cavity body filter of one of the present invention, not only tuning screw regulates the tuning surplus coordinated with harmonic oscillator, harmonic oscillator also is able to move left and right, increase with tuning screw coordinate scope, while ensureing tuning surplus, housing chamber reduces deeply, reduces filter size, improves the suitability of wave filter.
Description
Technical field
The present invention relates to a kind of wave filter, particularly relate to a kind of adjustable cavity body filter, belong to wireless communications application
Field.
Background technology
Fig. 1 is the filter construction schematic diagram of prior art, and as shown in Fig. 1, wave filter uses single cavity body structure, chamber
Deeply doing little, tuning screw is fixing on the cover board by nut, harmonic oscillator is inserted in the die casting of housing as mold insert, then
Being cast into high temperature metal liquid, along with the cooled and solidified of high temperature metal liquid, harmonic oscillator just combines with cavity, it is achieved resonance
Fixing of son.Filter construction shown in Fig. 1 the chamber of wave filter deeply do little on the basis of, can increase about tuning screw
The scope of movement, thus improve the tuning surplus of wave filter, it also avoid the generation of spark phenomenon.But, tuning screw
By chamber, deep and self bar length and installation dimension requirement are limited the scope that moves left and right so that the tuning that tuning screw coordinates with harmonic oscillator
Surplus is limited, and tuning utilization rate is low.
Summary of the invention
The deficiency that the present invention exists for prior art just, it is provided that a kind of adjustable cavity body filter.
For solving the problems referred to above, the technical solution used in the present invention is as follows:
A kind of adjustable cavity body filter, including housing, tuning screw, housing is cavity structure, and tuning screw passes housing
Side, it is characterised in that described wave filter also include can reduction regulation harmonic oscillator, harmonic oscillator is arranged on the correspondence of tuning screw
On the housing exterior walls of side, and having screw on outer wall, harmonic oscillator is cylindrical, and its one end has cylindrical cavity, and the other end is opened
There is screw thread, and thread head connection has cylindrical big end.
Further, described housing is set to facilitate the combined and spliced structure of sheet metal of installing/dismounting.
Further, described harmonic oscillator inner chamber is provided with the conductive layer cooperated with tuning screw, and tuning screw can be stretched
Enter in harmonic oscillator inner chamber coupled thereto.
Compared with prior art, the implementation result of the present invention is as follows for the present invention:
The adjustable cavity body filter of one of the present invention, not only tuning screw regulates more than the tuning coordinated with harmonic oscillator
Amount, harmonic oscillator also is able to move left and right, increase with tuning screw coordinate scope, it is ensured that tuning surplus while, housing chamber
Deep reduction, reduces filter size, improves the suitability of wave filter.
Accompanying drawing explanation
Fig. 1 is prior art filter structural representation；
Fig. 2 is the adjustable cavity body filter structural representation of the one shown in the present invention；
Wherein, 11 housings, 12 tuning screws, 13 harmonic oscillators, 14 screw threads, 15 big ends, 16 conductive layers.
Detailed description of the invention
Present disclosure is described below in conjunction with specific embodiments.
It is illustrated in figure 2 one of the present invention adjustable cavity body filter schematic diagram, including housing 11, tuning screw
12, housing 11 is cavity structure, and tuning screw 12 passes and be fixed on housing 11 side by nut, and described wave filter also includes
Can the harmonic oscillator 13 of reduction, harmonic oscillator 13 is arranged on the corresponding side housing exterior walls of tuning screw 12, and has spiral shell on outer wall
Hole, harmonic oscillator 13 is cylindrical, and its one end has cylindrical cavity, and the other end has screw thread 14, and the connection of screw thread 14 end has
Cylindrical big end 15.Described wave filter regulates the tuning surplus coordinated with harmonic oscillator 13, resonance not only by tuning screw 12
Son 13 also is able to move left and right, increase with tuning screw 12 coordinate scope, it is ensured that while tuning surplus, housing 11 chamber
Deeply, the size of tuning screw 12 and wave filter all reduce, improve the suitability of wave filter, reduce production cost.
Described housing 11 uses and facilitates the combined and spliced composition of sheet metal of installing/dismounting, easy for installation, it is to avoid casting
The complexity of moulding process, while using metallic plate to ensure that wave filter mechanical strength, also acts electromagnetic shielding simultaneously
Effect, improves the work quality of wave filter.
Described harmonic oscillator 13 inner chamber is provided with the conductive layer 16 cooperated with tuning screw 12, and tuning screw 12 can stretch into
Harmonic oscillator 13 inner chamber couples, it is achieved the tuning of wave filter.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all essences in the present invention
Any amendment, equivalent and the improvement etc. made within god and principle, should be included within the scope of the present invention.
