Abstract
The invention discloses a one-fourth wavelength arrester consisting of the following steps: an inner conductor is arranged in a shell; an inner conductor is arranged in a shell body; the shell body is perpendicularly and fixedly connected with the shell by a screw thread; brass material is adopted in the threaded connecting part between the shell body and the shell; other parts adopt aluminum material. As the structure of combining brass and aluminum is adopted in the shell body and the shell, the arrester has the advantages of light weight, manufacturing cost being reduced by one-fifth, low voltage standing wave ratio, outstanding third-order intermodulation and good air tightness. The characteristic impedance of the arrester is 50 ohm and the work center frequency of the arrester is 880 MHz.
Description
Technical field
The present invention relates to a kind of lightning arrester, particularly 1/4 wavelength type lighting arrester is mainly used among the microwave signal transmission system, prevents lightening pulse electric current defective communication equipment.
Background technology
Thunder and lightning is very big to the mankind's harm, pulsating current by the lightening pulse induction plays destruction to communication equipment, can cause communicating interrupt, at present generally on the transmission line between antenna and the equipment, connect lightning arrester, the thunder and lightning pulsating current can be imported the earth, not influence and hand over the normal transmission of signal frequently in the communication.
At present more common in coaxial lightning arrester series have gas discharge cast lightning arrester, high pass Archimedian screw type lightning arrester and 1/4 a wave length type lightning arrester, and wherein gas discharge cast lightning arrester impulse electricity number of times can not be too many, and lack useful life; High pass Archimedian screw type lightning arrester structure more complicated, the manufacturing cost height; By contrast, but 1/4 wave length type lightning arrester long period use, its basic structure as shown in Figure 1: be included in inner wires 2 are installed in the shell 7,8, insulator 5,6 is installed in respectively in the shell 7,8, and is enclosed within outside the inner wire 2.Inner wire 3 is installed in the shell body 1, and shell body 1 is installed by the screw thread vertical fixing with shell 7,8, and shell body 1 and shell 7,8 all are the brass products.Its operation principle is: 1/4 wavelength short-circuit line is short-circuit condition with the low frequency frequency spectrum pulsating current of lightning induction; lightning current is by lightning arrester shell 7,8 ground connection; import the earth; and the high-frequency signal of incoming traffic device transmission signal more than 300Hz is open-circuit condition; do not influence the operate as normal of equipment, play the purpose of lightning protection equipment.The shortcoming of this version is, 1, frequency band is wide inadequately.If require bandwidth, it is longer that main part and shell body 1 are just done, and is generally λ
0/ 2 relatively good (λ
0Be the intermediate frequency wavelength), physical dimension is bigger, waste material.If centre frequency is low more, 1/4 λ
0Short circuit is supported just long more, and material is waste more just.2, because shell body 1 and shell 7,8 adopt brass material to make, and the price of brass is very expensive, and than great, the surface needs electroplating processes again, so cause manufacturing cost high.
Summary of the invention
The objective of the invention is for overcoming the deficiencies in the prior art, a kind of 1/4 wavelength type lighting arrester of copper aluminium integrated structure formula is provided.
The technical solution used in the present invention is: comprise inner wire is installed in the enclosure, inner wire is installed in the shell body, and shell body is connected by the screw thread vertical fixing with shell, and shell body adopts brass material with shell in the part that is threaded, and other parts are aluminium.
The processing technology steps in sequence of shell body and shell is:
A, adopt aluminium alloy to make on shell, shell body is with hexagonal or quadrangle aluminum profile extrusion;
B, the aluminium of shell body after the machine-shaping and shell is partly carried out the decontamination processing of deoiling;
Blasting treatment is adopted on C, surface;
D, surface conductance oxidation processes;
The threaded portion that the aluminium part of E, the shell body after step D handled, shell and the brass material of shell body, shell are made adopts to press and cooperates, and vertical fixing links together.
The present invention is because shell body and shell all adopt copper aluminium integrated structure, and in light weight, manufacturing cost has reduced by 1/5; Voltage standing wave ratio is little, and performance of third order intermodulation is superior, and air-tightness is good; Its characteristic impedance is 50 ohm, and the work centre frequency is 880MHz.
Description of drawings
Below in conjunction with the drawings and specific embodiments the present invention is described in further detail.
Fig. 1 is a structure chart of the present invention;
Among the figure: 1. shell body; 2. inner wire; 3. inner wire; 5. insulator; 6. insulator; 7. shell; 8. shell; 11 sealing rings.
Embodiment
As shown in Figure 1, inner wire 2 is installed in shell 7,8, insulator 5,6 is installed in respectively in the shell 7,8, and is enclosed within outside the inner wire 2.Installation inner wire 3 in the shell body 1, shell body 1 is installed by the screw thread vertical fixing with shell 7,8, seals with sealing ring 11 in this installation place.Shell body 1 adopts brass material with shell 7,8 in the part that is threaded, and other parts are aluminium.
Add man-hour, adopt aluminium alloy to make the hexagonal or quadrangle aluminum profile extrusion of shell body 1 usefulness on shell 7,8.The machining process of shell body 1 and shell 7,8 is specific as follows: after the aluminium part machine-shaping of shell body 1 and shell 7,8, greasy dirt residual in the process engineering is cleaned up, otherwise piece surface can stay indelible greasy dirt impression after the oxidation processes.In order to increase aluminum products superficial density and hardness, again blasting treatment is adopted on the aluminum products surface.Owing to contain magnetisable material in the part abrasive blast equipment,, can not contact with part as iron plate etc., more magnetisable material can not be contained in the sand grains,, the third order intermodulation performance index will be had a strong impact on if magnetisable material flows into piece surface, so used the antimagnetizing processing, in order to avoid aluminum alloy surface magnetization in the sandblast process.At last aluminum products are carried out electric conductive oxidation and handle, can guarantee the brightness and the anti-corrosion property on surface.
Because the better performances that is threaded of brass, the hardness ratio aluminium alloy of brass is hard, screw thread in conjunction with the time do not have a phenomenon of gritting one's teeth, therefore, shell body 1 and shell 7,8 adopt brass material in the part that is threaded, copper aluminium two parts in conjunction with the time adopt and press cooperation, vertical permanent fixation links together.
Aluminium alloy belongs to non-magnetic material, can satisfy electric requirement of going up third order intermodulation, and aluminium alloy has enough intensity, weight approximately is 1/3 of copper material, price is more cheap than brass, compares with two kinds of different materials prices of volume, and aluminium alloy is about 1/5 of brass.
The present invention can be derived from other lightning arrester series of products.
