Sealing structure of radio frequency coaxial relay

The invention discloses a sealing structure of a radio frequency coaxial relay, which comprises a shell and a cavity, the cavity comprises a base and a radio frequency connector connected to the base, the base is arranged in the cavity, an annular sealing groove is formed in the outer side wall of the base, a sealing ring is clamped in the annular sealing groove, and the radio frequency connector is connected to the base. And the sealing ring partially extends out of the annular sealing groove and is in close contact with the inner wall of the shell. According to the radio frequency coaxial relay, only the outer side wall of the base of the cavity is provided with the groove, and the sealing ring is arranged in the groove, so that the problem that the sealing performance between the cavity and the shell of the radio frequency coaxial relay is poor is solved, the sealing structure is greatly improved, the sealing performance of the product is improved, and the quality improvement requirement of a user is met.
