Abstract
The utility model discloses a kind of novel broad band low frequency resonators, chamber lid including resonance single-chamber and for covering the resonance single-chamber, a resonance plate is fixed in the resonance single-chamber, meanwhile, a tuning disk not contacted with the resonance plate is fixed in the chamber lid.The resonator realizes that frequency is adjusted by changing tuning the distance between disk and resonance plate；The tuning sensitivity for improving resonator first, increases tuning range；Secondly, to accomplish the step of resonance single-chamber higher for resonance dish structure, can die casting on resonant cavity, reduce costs；Third for entire filter, only needs a kind of tuning disk that can realize that entire filter frequencies are adjusted, reduces variety of components since tuning dish structure increases tuning range.
Description
Technical field
The utility model relates to communication equipment fields, and in particular to a kind of novel broad band low frequency resonator.
Background technique
Currently, realizing the resonator of broad band low frequency filter frequency modulation as shown in Figure 1, being made of four parts: resonance single-chamber, humorous
Shake bar, tuning screw and four part of hex nut composition, and wherein resonant rod is band coil-like structure, and bottom, which has, is fixed on resonance
Screw via hole in single-chamber, upper inner diameter can be accomplished as big as possible, guarantee that tuning screw and resonance inner wall have sufficiently large safety
Distance；Tuning screw is full thread or half-thread；Resonance single-chamber is flat or with step.
Existing frequency is that the resonant rod of the broad band low frequency filter in 1000MHz is tep reel hollow tubular structure, passes through tune
Frequency is adjusted in the depth that frequency screw rod enters in single-chamber or resonant rod.It is this but since filter frequencies passband is wider
Structurally tuned screw rod is just widely different in the depth that each tuning cavity enters, and leads to the frequency modulation screw rod or resonant rod type of filter
Very much；Resonant rod is tep reel hollow tubular structure simultaneously, and screw rod adjusting is less sensitive, and the tune depth in resonant rod needs enough
Greatly, meet in this way debugging to need frequency point, then the height of resonant rod just need it is high as far as possible, in die design process
In, resonant rod largely can not die casting on cavity, need to individually produce and be fastened on above, higher cost.Therefore, existing
A kind of novel broad band low frequency resonator is at high cost, tuning range is small.
Summary of the invention
The utility model has invented a kind of novel broad band low frequency resonator aiming at the problem that background technique is proposed, should
Broadband resonator reduces the material variety of complete machine to reduce costs, while the resonator also increases tuning range.
The technical scheme is that a kind of novel broad band low frequency resonator, including resonance single-chamber (1) and for covering
The chamber lid (6) of the resonance single-chamber (1), while being fixed with a resonance plate (2) in the resonance single-chamber (1), meanwhile, the chamber lid
(6) a tuning disk (3) for not contacting and capable of being rotated relative to the resonance plate (2) with the resonance plate (2) is provided on.
Further, the tuning disk (3) is equipped with a threaded post (4) outstanding away from resonance plate (2) direction, meanwhile, institute
The screw hole (7) that setting is passed through for the threaded post (4) on chamber lid (6) is stated, meanwhile, pass through nut (5) after passing through for the screw thread
Column (4) is fixed on the chamber lid (6).
Further, the threaded post (4) is equipped with graduated scale, be easy to understand that the threaded post moves up and down away from
From.
Further, it is provided with step in the resonance single-chamber (1), the resonance plate (2) is fixed on the step.
Further, the tuning disk (3) is circular discs to facilitate rotation, meanwhile, the tuning disk (3) and the screw thread
Column (4) is integrally formed.
Further, the direction of the resonance plate (2) towards tuning disk (3) offers a circular trough, while the circle
The radius of slot is greater than the radius of tuning disk (3) to prevent the tuning disk (3) and the resonance plate (2) from touching.
Further, the maximum length of the threaded post (4) can guarantee that the tuning disk (3) can not touch resonance plate
(2).
Further, the top of the threaded post (4) is for convenience of the quadrangle or hexagon rotated
The utility model realizes that frequency is adjusted by changing tuning the distance between disk and resonance plate；Resonance is improved first
The tuning sensitivity of device, increases tuning range；Secondly, to accomplish the step of resonance single-chamber higher for resonance dish structure, it can
Die casting is reduced costs on resonant cavity；Third, since tuning dish structure increases tuning range, for entire filter
For, it only needs a kind of tuning disk that can realize that entire filter frequencies are adjusted, reduces variety of components.
