When the screw thread fails, the radio frequency connector can be poorly engaged, the signal contact is poor and even the signal transmission is completely lost due to the contact failure of the outer conductor.

As shown in fig. 4-5, for the second embodiment of the connector structure in the prior art, a through hole fixing structure is adopted to ensure the connection stability effect between the joints, since the method adopts a mode of additionally adding a fixing member to the circumferential direction of the nut to limit the rotation of the nut, while the loosening of the nut can be effectively avoided, the following disadvantages also exist:

1) a rope 01 made of metal or other materials is additionally added to fasten the materials;

2) a large structural space is required to perform the fastening operation;

3) is not suitable for repeated use occasions;

4) through holes 02 need to be formed in the circumferential direction of the nut to fix the rope 01, and the strength of the nut is affected while the processing is complex;

therefore, it is desirable to provide a radio frequency connector capable of solving the above-mentioned drawbacks and effectively ensuring stable connection.
