Description

A kind of waveguide coaxial converter for connecing cable

Technical field

The utility model is related to a kind of waveguide cable modular construction of raising through-put power, more particularly to a kind of cable that connects Waveguide coaxial converter, simple structure is easily realized, excellent electrical properties.

Background technology

Waveguide cable component is mainly two waveguide cable joints (equivalent to waveguide coaxial converter) with a softness Radio frequency coaxial-cable couple together, the product is mainly used in the microwave in the fields such as communication, ground satellite station, microwave measurement and sets In standby, with easy for installation, take up room little, through-put power is big, and voltage standing wave ratio is little, the low feature of insertion loss, according to electricity The outlet method of cable, is generally divided into orthogonal formula structure and termination formula structure.

The structure of existing market is that cable is accessed into a bit of coax segments, i.e. cable core welding or to being inserted into interior leading Body, cable shield is welded to shell, cable and segment coax segments is first matched, and then inner wire is deep into ripple as probe Guide cavity body intermediate excitation signal, in such structure, the same shaft end of introducing is located in the welding of heart yearn or with inner wire to inserting, interior Outer conductor diameter changes, it may appear that electric discontinuity, so as to mismatch, larger, the use power of reduction waveguide assemblies is lost.

The content of the invention

The purpose of this utility model is to overcome above-mentioned prior art not enough, there is provided a kind of to connect carrying for cable high-power Waveguide coaxial converter, the utility model simple structure, attaching are convenient, and power fail point is few, and electrical property is easily dimmable.

What the technical solution of the utility model was realized in：

A kind of waveguide coaxial converter for connecing cable, including bushing, nut, shell, waveguide, screw, cable shield, Cable insulation medium, cable core, the screen layer of cable is connected on bushing, and cable insulation medium is exhausted as cable coax segments Edge point, cable core is directly inserted in waveguide cavity as probe, is connected with the step block in waveguide cavity, screw Shell and waveguide are connected.

The screen layer of cable is welded on bushing.

The threaded coupling nut of inside the shell.

The utility model removes waveguide coaxial connecter section, and cable core is directly deep in wave-guide cavity wave, as probe, Make performance reach matching by adjusting the ladder allotment block in the middle of wave-guide cavity wave, reduce because internal and external conductor diameter change causes The power for discontinuously causing is reduced.

Specific embodiment

Content of the present utility model is described in further detail below in conjunction with the accompanying drawings.

Waveguide sheet is very big as powerful device, simple waveguide transmission mode through-put power is transmitted, if whole Increase the conversion of Waveguide coaxial in signal transmission, through-put power size just being determined by both waveguides sections and coaxial parts are middle minimum It is fixed.In the same manner during coaxial transmission, increase cable section, then the size of through-put power is by coaxial transformation segment and cable institute energy The minimum of a value of the power for bearing is determining.

With reference to shown in Fig. 1, Fig. 2, the structure by bushing 1, nut 2, shell 3, waveguide 4, screw 5, cable shield 6, Cable insulation 7, cable core 8 is constituted, and coax segments are directly accessed using cable, and the screen layer 6 of cable is welded on bushing 1, Directly using the medium 7 of cable, cable core 8 is directly inserted in wave-guide cavity wave the insulated part of coax segments as probe, with Step block in the cavity of waveguide 4 is connected, and by adjusting the size of length and height above step block electrical property, performance are adjusted Debug successfully, connected on shell 3 and waveguide 4 with screw 5, while tightening the afterbody nut 2 of connector.Can so reduce outer Carry out the introducing of medium (such as polytetrafluoroethylene (PTFE)), reduce the air gap, the probability of power fail is reduced, while making electrical property more Plus easily realize.

Nut 2 and bushing 1 are pushed to into successively cable, according to wire stripping size cable shield 6 is stripped out, the soldering of bushing 1 is arrived On cable, then the cable of bush end face is stripped out into insulating barrier 7, load shell 3, cable insulation and housing flange stripping is flat Together, cable core 8 is pruned, in being inserted into the cavity of waveguide 4, is connected on shell and waveguide cavity by flange with screw 5, together When tighten cable trailer nut 2, then by adjusting length and height above the cavity step block of waveguide 4 adjusting high frequency Energy.
