At the same time, a plurality of fixing protrusions are fixed on the surface of the connecting body, so that the connecting body and the outer conductor form a clamping connection, and the center pin and the connecting body form a clamping connection with the cooperation of the fixing ring, thereby forming a whole fixing and effectively preventing disconnection to improve the reliability.
