The pin connector has a first center conductor and a first outer conductor sleeved outside the first center conductor;

[0007] The jack connector includes:

[0008] A second outer conductor, with a circlip sleeved and connected inside one end of the second outer conductor;

[0009] A second center conductor, which is sleeved inside the second outer conductor, and an insulator is sleeved between the second center conductor and the second outer conductor;

[0010] A crown spring, which is sleeved and connected inside the second center conductor. When the pin connector is inserted and matched with the jack connector, the first center conductor is coaxially inserted into the crown spring, and the first outer conductor is coaxially inserted into the circlip.

[0011] As a further improvement and optimization of this solution, an annular groove is coaxially provided on the inner wall of one end of the second outer conductor, and the circlip is coaxially arranged in the annular groove.

[0014] As a further improvement and optimization of this solution, one end of the second central conductor has a mounting groove, and the crown spring is coaxially arranged in the mounting groove.

[0015] As a further improvement and optimization of this solution, the notch of the mounting groove is provided with a reduced opening.

[0016] As a further improvement and optimization of this solution, the outside of the pin connector has a limiting portion. When the pin connector is inserted and mated with the jack connector, the limiting portion is in limiting cooperation with one end of the second outer conductor.

[0017] As a further improvement and optimization of this solution, the insulator is a plastic part.
