Waterproof radio frequency coaxial connector

The invention relates to the technical field of radio frequency coaxial connectors, and discloses a waterproof radio frequency coaxial connector which comprises a connector shell thread sleeve, a tailstock and a fastening thread sleeve. A first sealing structure is arranged on a connecting interface of the tail seat and the rear end of the connector shell, and the first sealing structure is compressed in the process of screwing the tail seat to realize water prevention; a second sealing structure is arranged on the connecting interface of the fastening threaded sleeve and the tail seat, an elastic deformable sealing structure is adopted, the second sealing structure and the radio frequency coaxial cable are coaxially arranged and tightly sleeved, and the fastening threaded sleeve is screwed to the tail seat to push the second sealing structure to be gradually contracted and pressed to achieve water prevention. Reliable connection interface waterproofing is achieved between the connector shell and the tail bas
