Technical field
This utility model belongs to radio frequency (RF) coaxial connector technical field, is specifically related to a kind of have floating connection mechanism
TMA type radio frequency (RF) coaxial connector.
Background technology
Conventional TMA floatation style connector spring material spring strength is the least, and easy corrosion under harsh and unforgiving environments, thus
Make spring cisco unity malfunction, ultimately result in adapter electrical property unstable, it is impossible to meet and use requirement.
Summary of the invention
In order to overcome above-mentioned technological deficiency, the purpose of this utility model is to provide more excellent the having of a kind of mechanical performance
The TMA type radio frequency (RF) coaxial connector of floating connection mechanism, this adapter spring uses new material, and environmental resistance is superior, even
Connect reliable, mechanical electric stable performance, docking convenient.
For reaching above-mentioned purpose, this utility model adopts the following technical scheme that
A kind of TMA type radio frequency (RF) coaxial connector with floating connection mechanism, including the first shell 8, is arranged on outside first
Shell 8, away from the first insulator 5 and the second insulator 6 connected in cut cable, is fixed on the first insulator 5 and the second insulator 6
Interior jack 1, described first shell 8 has been press-fitted second housing 7, the first shell 8 and second housing 7 peripheral hardware away from connecting cut cable
It is equipped with the 3rd shell 4, is provided with spring 9 and packing ring 11 between the first shell 8, second housing 7 and the 3rd shell 4, is press-fitted to together
The first shell 8 can float under the support of spring with second housing 7；It is arranged on the lining that the first shell 8 connects in cut cable
Set 2 and line ball set 3 are tightened fixing by the female thread of nut 10 with the external screw thread of shell 8.
Described spring 9 uses stainless steel spring silk 1Cr18Ni9Ti.
Described jack 1 afterbody welds with cable inner conductor, and head is that cross recess closes up, and after heat treatment can ensure that connection
Device plugs together elasticity during use.
Compared to the prior art this utility model, has the advantage that
1, this utility model has the TMA type radio frequency (RF) coaxial connector of floating connection mechanism, easy for installation, is suitable for blindmate.
2., after selecting new material (stainless steel spring silk 1Cr18Ni9Ti), the pressure of spring is by original 25N～30N
Bring up to 30N～35N, be effectively improved the elastic force of spring, loosening after preventing connector head, seat from plugging together, it is ensured that adapter is at axle
When blindmate, electricity function index is good, and reliability is higher.
3., after using new material, spring resistant to rust ability has obtained good improvement, and electrical property, mechanical electric are also
More stable, reliable.
In sum, this utility model has the TMA type radio frequency (RF) coaxial connector of floating connection mechanism, easy for installation, suitable
Closing the connected mode of blindmate, by improvement further to spring material, spring strength, resistant to rust are satisfied by using requirement, electricity
Performance, mechanical electric are more superior, reliable.This utility model is mainly used in the states such as Aeronautics and Astronautics, electronics, boats and ships, weapons
Anti-key project.Also can be widely used to the communication of high reliability, radio and the technical field such as instrument and automatic control.

Jack 1 in one insulator 5 and the second insulator 6, described first shell 8 has been press-fitted second housing 7 away from connecting cut cable, the
One shell 8 is outside equipped with the 3rd shell 4 with second housing 7, is provided with bullet between the first shell 8, second housing 7 and the 3rd shell 4
Spring 9 and packing ring 11, be press-fitted to the first shell 8 together and can float under the support of spring with second housing 7；It is arranged on first
Shell 8 connects the lining 2 in cut cable and line ball set 3 is tightened fixing by the female thread of nut 10 with the external screw thread of shell 8.
As in figure 2 it is shown, as preferred implementation of the present utility model, described jack 1 one end is designed as scolding tin hole, with electricity
Cable inner wire welds；The cross recess of the other end closes up and heat treatment, it is ensured that the Elastic Contact of jack plugs together.
As it is shown on figure 3, as preferred implementation of the present utility model, described spring 9 uses stainless steel spring silk
1Cr18Ni9Ti, spring strength has reached requirement, improves the electricity function index of product.
