[0002] In microwave and high - speed test and measurement, a large number of multi - channel microwave components are adopted. These microwave test components require consistent phase and low insertion loss.

[0003] During the dynamic test process, the insertion loss and phase fluctuation of the components should be small. However, for the current common microwave components, even those with armor, it is difficult to meet the mechanical stability of long - life; therefore, a stress - releasing armor radio - frequency coaxial connector is proposed to solve the above problems.

[0006] The connector coupling nut is connected to one end of the first body, and the transition body is connected inside the first body; the connector sleeve, the armor welded cup and the armor tail tube are sleeved on the microwave coaxial cable.

[0007] Preferably, the first body is connected to the connector coupling nut through a connector snap - ring.

[0008] Preferably, a rubber ring is arranged between the outer wall of the first body and the inner wall of the connector coupling nut.

[0009] Preferably, a welded spacer insulator is connected to the outer wall of the welded center pin.

[0010] Preferably, the armor welded cup is welded to the armor tail tube.

[0011] The beneficial effects of the present utility model are as follows: For this stress relief armor radio frequency coaxial connector, a connector coupling nut is arranged at one end of the first body, and a transfer body is connected inside the first body; a connector sleeve, an armor soldering cup, and an armor tail tube are sleeved on the microwave coaxial cable.

It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present utility model. In addition, the terms "first", "second", "third" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0017] Next, the present utility model will be further described in conjunction with the accompanying drawings.

[0018] As Figures 1-3As shown, a stress-relieving armored radio frequency coaxial connector comprises a connector coupling nut 2, a first body 4, a transfer body 5, a welding center pin 6, a welding spacer insulator 7, a welding cup 8, a connector screw sleeve 9, an armored welding cup 11 and an armored tail pipe 12;

[0019] Specifically, the connector coupling nut 2 is connected to one end of the first body 4, the interior of the first body 4 is connected to the adapter body 5, and the first body 4 is connected to the connector coupling nut 2 through the connector clamp ring 3. A rubber ring 1 is provided between the outer wall of the first body 4 and the inner wall of the connector coupling nut 2.

[0020] Specifically, a connector screw sleeve 9, an armor welding cup 11 and an armor tail tube 12 are sleeved on the microwave coaxial cable 10, the left end of the microwave coaxial cable 10 is connected to the welding cup 8, the left end of the welding cup 8 is connected to the welding center needle 6, and the left end of the welding center needle 6 is connected to the adapter body 5; the outer wall of the welding center needle 6 is connected to the welding spacer insulator 7.

[0021] Specifically, the left end of the connector screw sleeve 9 is threadedly connected to the first body 4; the right end of the connector screw sleeve 9 is threadedly connected to the armor tail pipe 12; the armor welding cup 11 is located in the armor tail pipe 12. The armor welding cup 11 is connected to the armor tail pipe 12 by welding.

[0022] Specifically, the rubber ring 1, the connector coupling nut 2, the connector clamp 3 and the main body 4 of the connector are assembled together through a special clamp to form the main body of the connector, and the connector accessories, the connector screw sleeve 9, the armor welding cup 11 and the armor tail pipe 12 are pre-inserted into the microwave coaxial cable 10.

[0023] Use a wire stripping machine to strip the wires and tin them according to the connector stripping requirements. Weld the welding cup 8 to the outer conductor of the cable. Put the welding spacer insulator 7 on the inner conductor of the cable and weld the center pin 6. Insert the welded cable assembly into the connector body 5. Lock the connector screw sleeve 9. Pay attention to applying thread glue. Push the armor welding cup 11 to the tail of the connector body, and then weld the armor welding cup 11. This ensures that the length of the unwound wire is equal to the coaxial cable 10. This installation adjustment is very important to minimize the stress during mechanical vibration and cable bending. Then lock the armor tail tube 12. Thread glue needs to be applied when locking. After assembly, when the assembly vibrates and bends again, the stress is transmitted to the welding center pin 6, and the welding center pin 6 is clamped in the connector body through the welding spacer insulator 7. Ensure that it will not float. This ensures the stability of the connector and the RF coaxial assembly.

[0024] This stress relief armored RF coaxial connector meets the requirements of high-speed and microwave testing for RF components. By splitting the inner conductor inside the connector into two parts, all stress will not be transmitted to the test port when the component is mechanically vibrated and bent, thus achieving component stability.
