The concrete technical scheme realizing the object of the invention is:

A kind of elbow bend type radio frequency (RF) coaxial connector, feature is that it comprises swivel nut, rubber blanket, back-up ring, first medium body, the first inner wire, the first outer conductor, second medium body, the 3rd dielectric, the second outer conductor, screw and the second inner wire, described first outer conductor is L-type, and its inwall is provided with hangnail and screw thread; First inner wire is L-type, and its one end is provided with fluting jack; First medium body is identical with second medium body structure, which is provided with inclined-plane; Second outer conductor is provided with inner chamber and step; Screw outer wall is provided with screw thread; Second inner wire tail end is provided with hole; Described back-up ring is installed on the first outer conductor, rubber blanket and swivel nut are set in first outer conductor one end, first inner wire, the second inner wire, first medium body, second medium body, the 3rd dielectric are set in the first outer conductor, and the second outer conductor and screw suit are in the first outer conductor other end; Wherein: first medium body and second medium body are symmetrical arranged socket inner wire; Second outer conductor is connected with screw thread; After second inner wire welds with cable core, insert in the first inner wire.

Described first outer conductor has barb structure, for fixing first medium body and second medium body.

Described first inner wire is L-type, and afterbody is jack of slotting, and fluting jack is used for fixing the second inner wire.

Described first medium body and second medium body are equipped with oblique angle.

Described 3rd dielectric is fixed between second medium body and the second outer conductor.

The inner chamber of described second outer conductor is used for attached cable, and step is used for fixing the second outer conductor and is screwed in the first outer conductor.

Described second inner wire one end is contact pin structure, and tail end is provided with hole, for attached cable heart yearn.

The present invention is by changing the structure of inner wire, optimize the connected mode of cable and connector, make the welding process of cable and connector all outside the first outer conductor, avoid the scolding tin that may occur in Product Assembly process from structure to drop or the phenomenon such as inflow, and there is stronger auditability after welding, improve the reliability of product.

Embodiment

Consult Fig. 3 ~ 12, the present invention includes swivel nut 1, rubber blanket 2, back-up ring 3, first medium body 4, first inner wire 5, first outer conductor 6, second medium body 7, the 3rd dielectric 8, second outer conductor 9, screw 10 and the second inner wire 11.

Described first inner wire 5 and the second inner wire 11 adopt brass alloys or bell metal to make, first inner wire 5 is right-angle structure and L-type, afterbody is fluting jack 15, gap is had around right angle, dielectric constant is little, according to impedance computation, the impedance of this air section increases, and serves the effect that high resistance compensates; First inner wire 5 is fixed between first medium body 4 and second medium body 7.Second inner wire 11 afterbody is provided with hole 20, and for stube cable heart yearn 21, during use, the second inner wire 11 inserts in the first inner wire 5.

First medium body 4 and second medium body 7 adopt material polytetrafluoroethylene (PTFE) or polyether-ether-ketone (PEEK) material to make, and its one end is inclined-plane 16, for determining the size and Orientation in the first inner wire right angle gap, plays the effect of compensation.

First outer conductor 6 and the second outer conductor 9 are made up of copper alloy or stainless steel, and first medium body 4 and second medium body 7 are fixed by the first outer conductor 6.Inner chamber 17 on second outer conductor 9 is for the screen of attached cable 14, and step 18 is fixing for self.

Second outer conductor 9 can be fixed in the first outer conductor 6 by screw 10, is fixed together by screw thread 19 locking mode and then by cable 14 and connector.

Inner wire 5 of the present invention adopts right-angle structure, and the screen of cable 14 welds with the second outer conductor 9 freely, and cable core 21 welds with the second inner wire 11 freely.During attaching cable 14, second outer conductor 9 is connected by welding manner with the screen of cable 14, see accompanying drawing 10, after connection, wire stripping is carried out until expose heart yearn 21 along the second outer conductor 9 end face to cable, see accompanying drawing 11, cable core 21 is withstood the second outer conductor 9, second inner wire 11 through the 3rd dielectric the 8, three dielectric 8 and withstands cable dielectric body, cable core 21 is connected by welding manner with the second inner wire 11, sees accompanying drawing 12.Wherein, unnecessary for cable 14 scolding tin can be removed by wire stripping process, and after cable core 21 is connected with the second inner wire 11, cable end face outward appearance is still high-visible, and whole welding process is not all carried out in the first outer conductor 6, thus avoid the impact of unnecessary scolding tin on product electric property, and there is stronger auditability.Second outer conductor 9 is progressively fixed by screw 10, and in fixation procedure, the second inner wire 11 inserts in the first inner wire 5 gradually, until the second outer conductor 9 withstands the first outer conductor step.

When the present invention uses, cable 14 first welds with the second outer conductor 9, and then on cable 14, overlap the 3rd dielectric 8, cable core 21 welds with the second inner wire 11, then push in the first outer conductor 6, then screw 10 and the first outer conductor 6 are locked by screw thread 13; With the first outer conductor 6 clamping after swivel nut 1, rubber blanket 2 and back-up ring 3 are socketed.
