Core only has 0.2 millimeter.Conventionally, after TNC coaxial connector and cable attaching, it is easily caused cable during use and alters
Dynamic and rotation makes adapter inner wire shrinkage cavity and cable inner conductor fracture of root, and product reliability is poor.
Summary of the invention
For the shortcoming overcoming above-mentioned prior art to exist, the purpose of this utility model is to provide a kind of high reliable
TNC radio frequency (RF) coaxial connector, it is possible to connect the flexible cable of a diameter of 1.8 millimeters, difficulty when effectively reducing connecting cable, improves
Reliability after cable attaching.
For reaching above-mentioned purpose, this utility model by the following technical solutions:
A kind of high reliable TNC radio frequency (RF) coaxial connector, including the first shell 4, is provided with second housing in the first shell 4
5, second housing 5 is built with insulator 3, and insulator 3 is built with jack 1, between described second housing 5 and insulator 3 and jack 1
Fixed by epoxide-resin glue embedding, have half groove, cable inner conductor and jack 1 at jack 1 afterbody and be welded and fixed, second housing
5 are fixed with pressure by wire clamp 2 with cable shield；Screw 8 is threaded connection with the first shell 4, screw 8 by second housing 5,
First packing ring the 9, first sealing ring the 6, second packing ring 10 steps up to be fixed in the first shell 4.
Have groove on described first shell 4, in groove, be placed with the second sealing ring 7.
Compared to the prior art this utility model, has the advantage that
1, have half groove due to this utility model adapter at jack 1 afterbody, can visually weld during welding cable inner wire
Connect fixing, reduce welding difficulty, improve yield rate and work efficiency.
2, second housing 5, insulator 3 and jack 1 embedding are integrated, and cable inner conductor and jack 1 are welded and fixed the company of preventing
Connect device to jack time slotting 1 shrinkage cavity.
3, second housing 5 is fixed with pressure by wire clamp 2 with cable shield, it is ensured that second housing 5 is fixing with cable.
4. screw 8 is threadeded with the first shell 4, is clamped by second housing 5, it is ensured that second housing 5 loads the first shell 4
In, and be integrated with the first shell 4 attaching.
5, second housing 5, wire clamp 2 are fixed as one with cable, and cable assembly rotates when using, the first shell 4 and cable
Rotate together, it is ensured that cable inner conductor root not easy fracture, improve product reliability.
6, have groove on the first shell 4, in groove, be placed with the second sealing ring 7, it is ensured that adapter is installed with panel
Time sealing.
In sum, this utility model ensure that the stability after cable and adapter attaching and reliability, improves electricity
The yield rate during welding of cable inner wire, improves work efficiency.This utility model is mainly used in Aeronautics and Astronautics, electronics, ship
The national defence key project such as oceangoing ship, weapons and the communication of high reliability, radio and the technical field such as instrument and automatic control.

Detailed description of the invention
Below in conjunction with the accompanying drawings structural principle of the present utility model and operation principle are described in more detail.
As it is shown in figure 1, a kind of high reliable TNC radio frequency (RF) coaxial connector of this practicality, including the first shell 4, the first shell 4
Inside being provided with second housing 5, second housing 5 is built with insulator 3, and insulator 3 is built with jack 1, shell 5 and insulator 3 He
Jack 1 is fixed by epoxide-resin glue embedding, has half groove, cable inner conductor and jack 1 at jack 1 afterbody and is welded and fixed, the
Two shells 5, wire clamp 2 are fixed with pressure with cable outer conductor.Screw 8 is by second housing the 5, first packing ring the 9, first sealing ring 6, second
Packing ring 10 steps up to be fixed in the first shell 4.Have groove on first shell 4, in groove, be placed with the second sealing ring 7.
As in figure 2 it is shown, second housing 5, insulator 3 and jack 1 use epoxide-resin glue embedding to fix.Cable inner conductor with
Jack 1 is welded and fixed.Therefore can remove from second housing 4 when second housing 5, insulator 3 and jack 1 weld, improve
Reliability after welding quality and welding.Solve adapter to jack Shrinkage Problem time slotting.As shown in Figure 4 and Figure 5, due to
Jack 1 afterbody has half groove, facilitate jack afterbody when welding visual cable inner conductor attaching put in place, improve welding quality simultaneously
And the reliability after welding.
As it is shown on figure 3, second housing 5, insulator 3 and jack 1 are fixed as one, second housing 5 leads to cable shield
Cross wire clamp 2 to be fixed with pressure.Cable assembly rotates when using, and second housing 4 rotates together with cable, it is ensured that cable inner conductor root
Not easy fracture, improves product reliability.
Assembling process of the present utility model is: second housing 5, insulator 3 and the jack 1 first embedding being integrated is from
One shell 4 removes, cable inner conductor is connect with jack 1 afterbody half slot welding, then passing through wire clamp 2 with cable shield, to be press-fitted be one
Body.Then it is loaded in the first shell 4, is positioned by step in the first shell 4.Ensure adapter interface；Secondly by
One packing ring the 9, first sealing ring the 6, second packing ring 10 and nut 8 are threadeded with the first shell 4, are clamped by second housing 5, real
Show the connection of cable and adapter.
