Abstract

The utility model discloses a kind of radio frequency the moon head short-circuiting devices, including outer conductor and jack short circuit inner wire, the jack short circuit inner wire includes jack inner conductor and short-circuit block, the jack inner conductor is fixedly connected with the short-circuit block, the material of the jack inner conductor is beallon, and the material of the short-circuit block is metallic conductor.Integral type jack short circuit inner wire is changed to split structure, is fixedly connected and is composed with short-circuit block by jack inner conductor, and wherein jack inner conductor still uses beallon, and short-circuit block is then using the relatively cheap and easy to process metallic conductor material of price.Jack inner conductor and short-circuit block are individually processed, and difficulty of processing is greatly reduced, and need not substantially remove allowance.Using the cloudy head short-circuiting device of radio frequency the moon head short-circuiting device through actual test, electrical property complies fully with requirement.

Description

A kind of radio frequency the moon head short-circuiting device

Technical field

The utility model is related to short-circuit inner wire field more particularly to a kind of radio frequency the moon head short-circuiting devices.

Background technology

Radio-frequency-short device is the terminal part for realizing radiofrequency signal total reflection function, is generally connected using polarized RF coaxial Device is connect, therefore male short-circuiting device and cloudy head short-circuiting device can be divided into.Jack short circuit inner wire is in the cloudy interior connection of head short-circuiting device Conductor and outer conductor to realize the core part of short-circuit function, jack short circuit inner wire in order to ensure the elasticity of jack structure, It is required that material using high resiliency, low-resistivity alloy, generally uses beallon.Existing jack short circuit inner conductor structure is major part Shape is followed closely, both ends diameter differs greatly, and since raw material diameter is necessary for diameter at butt end, material consumption is relatively large, and And it shapes process and also largely to remove allowance.Since beallon material price and difficulty of processing are far above ordinary copper Alloy, therefore the material of the jack short circuit inner wire and processing cost are relatively high.

Utility model content

In order to solve the above technical problems, the utility model provides a kind of split type structure jack short circuit inner wire.

A kind of radio frequency the moon head short-circuiting device, including outer conductor and jack short circuit inner wire, the jack short circuit inner wire include Jack inner conductor and short-circuit block, the jack inner conductor are fixedly connected with the short-circuit block, and the material of the jack inner conductor is The material of beallon, the short-circuit block is metallic conductor.

In said program, the metallic conductor is the one of which of brass, aluminium, steel.

In said program, the jack inner conductor and the short-circuit block using is threadedly coupled, be interference fitted connection, splicing or The one of which of welding.

The beneficial effects of the utility model are compared with prior art：Integral type jack short circuit inner wire is changed to split type knot Structure is fixedly connected with short-circuit block by jack inner conductor and is composed, and wherein jack inner conductor still uses beallon, and short-circuit The metallic conductor material that block then uses price relatively cheap and easy to process.Since jack inner conductor diameter is smaller, can be used small Diameter beryllium copper material shapes, and need not largely remove surplus, therefore the consumption of beryllium copper material is greatly reduced.Meanwhile it adopting It is greatly reduced with the short-circuit block difficulty of processing of brass, aluminium or Steel material, also need not substantially remove allowance.It is aobvious and easy See, the material and processing cost of radio frequency the moon head short-circuiting device are all substantially reduced.It is passed through using the cloudy head short-circuiting device of radio frequency the moon head short-circuiting device Actual test, electrical property comply fully with requirement.

Description of the drawings

Fig. 1 is the structural schematic diagram of the utility model radio frequency the moon head short-circuiting device；

Reference numeral：1, outer conductor, 2, jack inner conductor, 3, short-circuit block.

Specific implementation mode

With reference to the accompanying drawings and examples, specific embodiment of the present utility model is described in further detail.Below Embodiment is not intended to limit the scope of the present invention for illustrating the utility model.

As shown in Figure 1, a kind of radio frequency the moon head short-circuiting device, including outer conductor 1 and jack short circuit inner wire, the jack short circuit Inner wire includes jack inner conductor 2 and short-circuit block 3, jack inner conductor 2 and short-circuit block 3 using be threadedly coupled, be interference fitted connection, It is glued or a kind of mode of welding is fixedly connected, jack inner conductor 2 selects material to be process for beallon, and short-circuit block 3 selects Can be that brass or aluminium or steel are process with metallic conductor material.Jack short circuit inner wire uses split structure, due to inserting Inner wire 2 diameter in hole is smaller, and minor diameter beryllium copper material can be used and shape, need not largely remove surplus, therefore substantially subtract The consumption of beryllium copper material is lacked.Meanwhile short-circuit block 3 is processed using the material of brass, aluminium or steel, difficulty of processing is greatly reduced, Also allowance need not substantially be removed.It is clear that the material and processing cost of radio frequency the moon head short-circuiting device are all substantially reduced.It adopts With the cloudy head short-circuiting device of radio frequency the moon head short-circuiting device through actual test, electrical property complies fully with requirement.

Above example is only to illustrate the technological thought of the utility model, and the protection model of the utility model cannot be limited with this Enclose, it is every according to the utility model proposes technological thought, any change is made on the basis of technical solution, each falls within this reality With in novel protected range.
