Description
Technical field
The utility model relates to wireless telecommunications, particularly relates to a kind of coaxial cavity cross coupling structure.
Background technology
Along with developing rapidly of wireless telecommunication system, the requirement to mass of system simultaneously also improves constantly, and in order to prevent to have in the required frequency range interference of other signal, improves the utilance of frequency range.System operator is more and more higher to the performance requirement of filter.
As element with distributed parameters,, constitute band pass filter by 1/4 wavelength coaxial cavity filter,, determine type, progression, the structure of filter according to related wave filter technology index with the capacitive coupling of lumped parameter; To the cross-couplings with precipitous band external characteristic be with four chambeies intersect and three chamber cross-couplings forms as element circuit, it is independent separately that the band on road of having found respectively to economize on electricity when continuous transmits zero point outward, these characteristics make the filter of this structure regulate easily, improve the outer index performance index that suppress of band.Along with frequency more and more high-band to suppress index outward more and more stricter, traditional capacitive cross coupling structure does not satisfy the outer inhibition of band index request.
In traditional coaxial cavity filter, the cross-linked way of realization of capacitive is to fixedly install a capacitive coupling assembly on the dividing wall between two coaxial cavity resonators
The capacitive coupling assembly does not wait coupling conductors to form by an insulated support, be uneven in length tuning screw and size, elder generation is screwed to tuning screw in the insulated support and guarantees insulated support structure placed in the middle, then two coupling conductors is screwed on the tuning screw and guarantees between two parties coupling conductors and tuning screw to be welded; Form a capacitive coupling assembly; Offer mounting groove on the dividing wall between two cavitys, the capacitive coupling assembly is positioned in the mounting groove, and is symmetrically arranged between two coaxial cavities.
This insulated support processes for the polytetrafluoroethylene (PTFE) material mechanical; Tuning screw is the moulding of brass (H62) machining.Coupling conductors is the moulding of brass (H62) machining, and the higher and loaded down with trivial details consistency of installation step of this capacitively coupled manufacturing cost, stability are also poor, and very high revenge rate is arranged when very high assembling is arranged.
Summary of the invention
Technical problem to be solved in the utility model is exactly to provide a kind of coaxial cavity cross coupling structure for the defective that overcomes above-mentioned prior art existence.
The purpose of this utility model can be achieved through the following technical solutions: a kind of coaxial cavity cross coupling structure, it is characterized in that, comprise moulding, threaded rod, two packing rings and two coupling conductors, described threaded rod is arranged on the moulding along the left and right sides of moulding, this moulding is positioned at the center of threaded rod, described two packing rings are symmetrically set on the threaded rod, described two coupling conductors are symmetrically set on the threaded rod, and these two coupling conductors lay respectively at the outside of two packing rings.
The both sides, front and back of described moulding are equipped with vertical mounting groove.
Described moulding is a polysulfones PSU moulding.
Described threaded rod is copper threaded rod.
Described packing ring is copper packing ring.
Compared with prior art, the utlity model has following advantage:
1, simple in structure, novel, practical;
2, stable performance, reliable;
3, cost low, be easy to make.

Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a decomposition texture schematic diagram of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
As shown in Figure 1, 2, a kind of coaxial cavity cross coupling structure, comprise moulding 1, threaded rod 2, two packing rings 3 and two coupling conductors 4, described threaded rod 2 is arranged on the moulding 1 along the left and right sides of moulding 1, this moulding 1 is positioned at the center of threaded rod 2, described two packing rings 3 are symmetrically set on the threaded rod 2, and described two coupling conductors 4 are symmetrically set on the threaded rod 2, and these two coupling conductors 4 lay respectively at the outside of two packing rings 3.
The both sides, front and back of described moulding 1 are equipped with vertical mounting groove 10; Described moulding 1 adopts polysulfones PSU moulding; Described threaded rod 2 adopts copper threaded rod; Described packing ring 3 adopts copper packing ring.
Injection-molded body: the moulding of band copper rod material threaded insert, injected plastics material is polysulfones (PSU).Can keep good consistency and easy to assembly;
Copper packing ring: can require to increase or reduce to reach and satisfy the performance index requirement according to product performance index.Highly versatile easy to use;
Coupling conductors: can require to increase or reduce diameter and thickness requirement according to product performance index.Highly versatile is convenient to be used.
According to the cross-linked power of capacitive, adjust copper packing ring and the coupling conductors dimensional structure performance requirement that can touch the mark.Coupling conductors was both tightened and can be used.Use flexibly, handled easily, reusable, cost is low.
