The inner conductor is provided with a step. The structures of the first dielectric body and the second dielectric body are the same. A plurality of air columns are uniformly distributed along the circumference. The second liner is provided with a step. The threaded sleeve, the rubber pad, and the retaining ring are in sleeve connection. The inner conductor, the first dielectric body, the second dielectric body, the first liner and the second liner are installed in the outer conductor. The outer conductor and the threaded sleeve are in clamp connection through the retaining ring. According to the spread spectrum RF coaxial connector, through reducing the dielectric constant of a transmission medium, the connection mode of a cable and a connector is optimized, the overall rise of connector product user frequency is realized, the original 11GHz is raised to 18GHz, and the application need of a higher frequency is satisfied.
Description
Technical field
The present invention relates to technical field of electric connectors, especially a kind of can the N train of radio frequency coaxial connector of spread spectrum.
Background technology
The use of the N train of radio frequency coaxial connector of prior art generally uses according to the highest 11GHz of using of standard regulation, once exceed the frequency of regulation, electricity function index reduces rapidly, cannot meet use, limits the scope of application of product.Along with the development of whole set equipment, improve constantly the requirement of coaxial connector, under needing the condition can exchanged at connector interface, improve frequency of utilization, peak demand is to 18GHz.Existing connector construction cannot meet, and to adopting new connector construction, must could improve the frequency of utilization of product.
Summary of the invention
The radio frequency (RF) coaxial connector of a kind of spread spectrum provided for the deficiencies in the prior art is provided, it is by reducing the dielectric constant of transmission medium, optimize the connected mode of cable and connector, achieve the Integral lifting of connector product frequency of utilization, rise to 18GHz by original 11GHz, meet the application demand of higher frequency.
The concrete technical scheme realizing the object of the invention is:
A kind of radio frequency (RF) coaxial connector of spread spectrum, feature is that it comprises swivel nut, rubber blanket, back-up ring, first medium body, inner wire, the first lining, second medium body, outer conductor, the second lining and screw, described inner wire is provided with step, first medium body is identical with second medium body structure, circumferentially evenly arranges several air column; Second lining is provided with step, and described swivel nut, rubber blanket and back-up ring are socketed; Inner wire, first medium body, second medium body, the first lining and the second lining are set in outer conductor, outer conductor and back-up ring clamping; Wherein: first medium body and second medium body socket inner wire, the first lining and the second lining are socketed first medium body and second medium body, and the second lining is connected with screw thread.
Described first medium body and second medium body adopt on polytetrafluoroethylene or polyetheretherketonematerials materials, circumferentially evenly arrange several air column.
Inner wire is fixed between first medium body and second medium body by the step on described inner wire.
Step on described second lining is used for attached cable.
The present invention adopts and arranges step at inner wire afterbody, and during product attaching cable, the step of inner wire afterbody withstands first medium body, realizes the location of inner wire.On first medium body and second medium body, circumferentially evenly air column is set, obtains the blending agent body of air and dielectric material.And the dielectric constant of air is minimum in all material, thus reduce the dielectric constant of transmission medium.Cable is connected with connector second lining, second lining is provided with step, cable end face can be withstood during attaching cable, realize the location of cable, the air section impedance at step place is high simultaneously, plays the effect that high resistance compensates, thus achieves the Integral lifting of connector product frequency of utilization, rise to 18GHz by original 11GHz, meet the application demand of higher frequency.

Embodiment
Consult Fig. 1 ~ 6, the present invention includes swivel nut 1, rubber blanket 2, back-up ring 3, first medium body 4, inner wire 5, first lining 6, second medium body 7, outer conductor 8, second lining 9 and screw 10.Described inner wire 5 adopts brass alloys or bell metal to make, and be air dielectric around the step 11 of afterbody, dielectric constant is little, and according to impedance computation, the impedance of this air section increases, and serves the effect that high resistance compensates.Step 11 is fixed in the middle of first medium body 4 and second medium body 7.
First medium body 4 and second medium body 7 adopt material polytetrafluoroethylene (PTFE) or polyether-ether-ketone (PEEK) material to make, on it, equally distributed air column 12 is 4 ~ 6, for reducing the dielectric constant of dielectric itself, and then improve transmission rate and frequency of utilization.
First lining 6 and the second lining 9 are made up of copper alloy, the first lining 6 for mounting medium body, the external diameter of its internal diameter determination inner wire 5 ambient air medium.Second lining 9 is for the screen of attached cable, and spacing for cable shield of the step 13 on the second lining 9, the air before step 13 is used for the impedance mismatch phenomenon that compensation connector and cable connection procedure occur, improves frequency of utilization.
First lining 6 and the second lining 9 can be fixed in outer conductor 8 by screw 10, are fixed together by screw thread 14 locking mode and then by cable and connector.
When the present invention uses, cable first welds with the second lining 9, on cable, then overlaps second medium body 7, and be socketed with inner wire 5, push in outer conductor 8 after putting the first lining 6 and first medium body 4 again, then screw 10 and outer conductor 8 are locked by screw thread 14; Swivel nut 1, rubber blanket 2 and back-up ring 3 are socketed rear and outer conductor 8 clamping.
