[0040] Working principle: When using the ultra-fine coaxial connector, the operator first pulls down the fixing ring 2. The fixing ring 2 drives the four first fixing rods 13 and the four second fixing rods 14 to move down and compress the four springs 12. Then the operator picks up the female head 5 and fixes it together with the mounting sleeve on the male head 1 through the nut 4.

[0041] Then, the staff loosened the fixing ring 2, and the four springs 12 reset, causing the fixing ring 2, the four first fixing rods 13 and the four second fixing rods 14 to move upward, so that the four first fixing rods 13 and the four second fixing rods 14 are engaged into the interior of the corresponding second fixing sleeve 9 and the first fixing sleeve 6.

[0042] Among them, by setting four first fixing rods 13, four second fixing rods 14, four springs 12, four second fixing sleeves 9 and four first fixing sleeves 6, the nut 4 as a whole is limited, preventing the male head 1 and female head 5 from loosening due to relative rotation caused by vibration;
