Coaxial cable connector structure
A coaxial cable connector structure including a sleeve and an annular nut on the front end of the sleeve is disclosed, wherein an inner tube is disposed inside the sleeve for connecting the coaxial cable, and a spring is disposed on the bottom of the annular nut for the end surface of the connection base towards the annular nut to contact the spring and electrically connect the inner tube when the connection base is screwed into the annular nut, so that the coaxial cable connector structure can transmit signals when it is not completely screwed onto the connection base, and provide the effect of vibration suppression from the compressed spring having its two ends abutted against the bottom of the annular nut and the end surface of the connection base by the elastic restoring force when the connection base is completely screwed onto the connection base.
