[0002] The naming of RF coaxial connectors consists of two parts: the main code and the structure code, separated by a short horizontal line. The main code of RF connectors adopts the internationally common main code. The naming of different structural forms of specific products is specified by detailed specifications. The structure form represents the structure of the RF connector.

[0003] A radio frequency connector with Chinese patent number CN213782376U includes a connector housing, one end of which is coaxially provided with a female insulator, and the female insulator is axially provided with a first stepped through hole and a guide cone hole that are interconnected. The present application has the effect of blind mating of terminals with pins such as glass insulators, effectively improving the connection efficiency under high integration.

[0004] During use, RF connectors generally use a single locking or snap-in connection method to limit the connection. The single connection protection causes the connection of the RF connector to be unstable during use, which is prone to loosening, and is not conducive to ensuring the use efficiency of the RF connector. Therefore, a RF connector with stable connection is needed to solve the above problems.

[0005] To this end, a radio frequency connector with stable connection is proposed. Utility Model Content

[0011] Further preferably, the outer ring of the second docking device is provided with an external thread, and the ends of the two flexible limiting circular plates that are away from each other are fixedly connected with a corrugated sleeve ring.

[0012] Further preferably, the corrugated sleeve ring is located outside the extended wire, and one end of the corrugated sleeve ring away from the flexible limiting circular plate is fixedly connected to a connecting thin ring.

[0013] Further preferably, an outer end of the connecting thin ring is bonded and connected with an insulating tape layer, and the insulating tape layer limits the connecting thin ring and the extension wire to each other.

[0014] Further preferably, the first butt connector and the second butt connector are threadedly connected via an internal thread and an external thread.

[0015] The embodiment of the utility model has the following advantages due to the adoption of the above technical solution:

[0016] 1.
