Abstract

The utility model relates to a coaxial cavity filter lightning protection configuration, which belongs to microwave communication technical field. In order to solve the anti-lightning problem of prior coaxial capacitive-coupled cavity filter on the antenna terminal, the utility model adopts a piece of 1/4 lambda length silvered copper wire. A silvered copper screw is arranged on the cavity. Both ends of the silvered copper wire are welded on the screw and an antenna connector. The utility model is simple on structure, easy for producing, with anti-lighting impact ability, which is suitable for microwave coaxial cavity filter.

Description

A kind of coaxial cavity filter lightning protection structure
Technical field
This patent relates to a kind of coaxial cavity filter lightning protection structure, belongs to technical field of micro communication.
Background technology
Existing mobile communications system still in third generation WCDMA mobile communication base station, all can realize the transmission and the reception of signal of communication with the collocation of coaxial cavity filter and antenna simultaneously no matter be the GSM base station.Thunder and lightning is a kind of common natural calamity; the electric equipment of often breaking and linking to each other with communication line; coaxial cavity filter as the crucial microwave telecommunication devices of receiving and transmitting signal in use; must consider lightning Protection Design; existing coaxial cavity filter all adopts silver-coated copper wire; one end is connected on the resonator, and the other end is connected and realizes inductive coupled and anti-lightning strike surge on the antenna port, and such structure can cause the transmission characteristic drift of coaxial cavity filter and the reduction of reliability.
Summary of the invention
At the above-mentioned defective of prior art lightning Protection Design, this patent will solve the problem of the inductive coupled lightning protection structural transmission of coaxial cavity filter antenna end characteristic drift.
For solving the problems of the prior art, this patent provides a kind of coaxial cavity filter antenna end capacitive coupling lightning protection structure, with the length silver-coated copper wire that is 1/4 λ, a silver-plated copper screw is installed on cavity, the silver-coated copper wire two ends are welded on screw and the antenna connector, and this structure has the characteristic of anti-lightning impulse.
In this patent, silver-coated copper wire also can adopt the silver-plated material of other metal wire.
In this patent, the metal silver-coated copper wire can be a silver-coated copper wire, also can be sheffield plate.
In this patent, silver-coated copper wire is installed on screw and the antenna connector, does not contact resonatron.
The beneficial effect of this patent is that silver-coated copper wire does not contact resonatron, has avoided the influence to the resonatron resonance characteristic, has improved the reliability of coaxial cavity filter, has realized the lightning protection requirement of coaxial cavity filter.
Description of drawings
Below in conjunction with drawings and Examples this patent is described further, in the accompanying drawing:
Fig. 1 is a this patent coaxial cavity filter lightning protection structural representation.1 is antenna connector among the figure, and 2 is screw, and 3 is solder joint, and 4 is silver-coated copper wire.
Embodiment
In the preferred embodiment of this patent, antenna connector 1 is selected 7/16 connector for use, choose the silver-coated copper wire 4 of a φ 1mm, silver-plated copper screw 2 is installed in the appropriate location punching on cavity, silver-coated copper wire 4 two ends are welded on respectively on antenna connector 1 and the silver-plated copper screw 2, just made a lightning protection structure, this structure has anti-lightning strike surge capacity.
To describe the characteristics of a kind of coaxial cavity filter lightning protection structure of present embodiment below in detail.
1, the length of described silver-coated copper wire is 1/4 wavelength.
2, described silver-coated copper wire is fixing by welding.
3, described silver-coated copper wire is in tensioned state, can not occur rocking and being shifted.
Adopt a kind of coaxial cavity filter lightning protection structure of this patent, easy to process, quick for installation, reliability is high, meets the requirement of IEC61000-4-5 lightning surge immunity to interference, is applicable to the microwave coaxial cavity body filter.
