[0035] See also Figure 7 A 5G fast-plug high-power RF coaxial connector, the plug structure 4 includes a support seat 41, a plug 42, a protrusion 43, a plug slot 44, a plug inner conductor 45, and a connecting wire 46. The plug 42 is plugged into the inner side of the front end of the connecting cylinder 11, the support seat 41 is fixed to the rear end of the plug 42, the top of the plug 42 is fixed with a protrusion 43, the middle of the plug 42 is provided with a plug slot 44, and the rear end of the support seat 41 is connected to the connecting wire 46.

[0036] In some embodiments, the interior of the plug slot 44 is a cavity-like structure, and the inner wall of the plug slot 44 is covered with a plug inner conductor 45, the ejector pin 17 is embedded in the inner side of the plug slot 44, and the ejector pin 17 is in contact with the inner wall of the plug inner conductor 45, the plug slot 44 adopts a split groove closing structure, and the mouth is designed with chamfered corners to increase the guiding effect and reduce the risk of sharp point discharge. The plug inner conductor 45 is made of a metal material with high yield strength and fatigue resistance, and the plug-in and unplugging life can reach more than 500 times, which can meet the application scenarios where the connector is frequently plugged and unplugged.

[0037] In summary, when in use, the socket cable 3 can be connected to the instrument, and the connecting wire 46 can be connected to the mobile device, which serves as a bridge for the transmission signal between the instrument and the mobile device. When the socket structure 1 and the plug structure 4 need to be docked;

[0038] Align the plug groove 44 of the plug 42 with the ejector pin 17 on the connecting tube 11 and insert the plug 42 so that the ejector pin 17 is embedded in the plug groove 44. When the plug 42 is embedded in the connecting tube 11, the protrusion 43 slides in the movable groove 14 to guide the plug 42. As the plug 42 goes deeper, the protrusion 43 is stuck in the limit groove on the movable groove 14.

[0039] Then, the threaded sleeve 13 is rotated clockwise to make the threaded sleeve 13 threaded on the connecting tube 11 and move toward the front end of the connecting tube 11, so that the threaded sleeve 13 wraps the movable groove 14, thereby limiting the position of the protrusion 43, and achieving the docking of the socket structure 1 and the plug structure 4, changing the traditional need to use a special wrench for auxiliary tightening, thereby increasing the installation efficiency;

[0040] When the threaded sleeve 13 moves forward, the push block 152 is pressed, so that the push block 152 drives the connecting rod 154 to swing through the movable seat 153, so that the connecting rod 154 drives the pressing block 155 to move upward. Similarly, the pressing block 155 on the clamping structure at the lower end moves downward, and the dynamic compression spring 156 is deformed. When the threaded sleeve 13 rotates to fit the rear end of the positioning structure 15, the downward pressure on the push block 152 is released, and the elastic potential energy of the compression spring 156 to restore the deformation drives the pressing block 155 to clamp the threaded sleeve 13, thereby preventing the threaded sleeve 13 from loosening and increasing the connection stability of the socket structure 1 and the plug structure 4.

[0041] Similarly, when the socket structure 1 and the plug structure 4 need to be disassembled, it is only necessary to release the pressing push block 152 to release the clamping of the threaded sleeve 13, rotate the threaded sleeve 13 counterclockwise to release the positioning of the protrusion 43, and then separate the socket structure 1 and the plug structure 4.

[0042] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
