[0002] RF coaxial connectors are used to connect RF devices to RF signal transmission lines. They usually consist of two parts: an outer connector (plug) and an inner connector (socket), which are connected to the RF device and the RF transmission line respectively to transmit high-frequency signals.
[0003] Patent No. "CN215451964U" discloses a "push-in type RF coaxial connector". The device is provided with a push plate and a mounting hole. When in use, the push plate is rotatably connected to the outer shell by connecting the mounting hole. The position of the push plate can be adjusted so that the connector is fully connected to the connecting seat. As the number of plug-in installations of the male connector and the female connector increases, it is very easy to cause the pins inside the male connector to be misaligned and offset, thereby causing the concentricity of the inner and outer conductors of the connector to deviate, affecting the subsequent docking and use. However, the above device has not made any improvements to this problem, and the overall practical effect is poor. Utility Model Content
[0004] The purpose of the present utility model is to solve the above-mentioned problem and to propose a rotatable installation type RF coaxial connector, which improves the existing RF coaxial connector. As the number of times the male connector and the female connector are plugged and installed increases, the pins inside the male connector are easily misaligned, which in turn causes the concentricity of the inner and outer conductors of the connector to deviate, affecting the subsequent docking and use. However, the existing device has not made improvements to this problem, and the overall practical effect is poor.
[0005] A rotatably mounted radio frequency coaxial connector comprises a male connector body and a female connector body: the male connector body is located on the side of the female connector body, a rotating mounting mechanism is connected and arranged between the male connector body and the female connector body, a locking control mechanism is arranged on the outside of the rotating mounting mechanism, an auxiliary centering mechanism is arranged on the inside of the male connector body, the rotating mounting mechanism comprises a docking ring, a threaded groove and a threaded ring, a docking ring is arranged on the side outer wall of the male connector body, a threaded groove is opened on the side inner wall of the docking ring, a threaded ring is arranged on the side outer wall of the female connector body, the inner ring diameter of the docking ring is equal to the outer ring diameter of the threaded ring, and a threaded connection is formed between the threaded ring and the threaded groove.
[0006] Preferably, the locking control mechanism comprises a first limiting ring and a resisting snap ring, the side outer wall of the docking ring located at the edge is provided with the first limiting ring, and the side outer wall of the first limiting ring is provided with a resisting snap ring.
[0007] Preferably, a second limiting ring is provided on the side outer wall of the female connector body located at the edge.

[0009] Preferably, the auxiliary centering mechanism comprises a positioning ring and a mounting ring, the inner wall of the side edge of the male connector body is provided with a positioning ring, and the inner wall of the side edge of the positioning ring is provided with a mounting ring.
[0010] Preferably, the interior of the mounting ring is configured as a cavity structure, and the inner wall of the mounting ring is configured as an opening structure, and sliding parts are equidistantly and circumferentially slidably mounted on the inner wall of the mounting ring.
[0011] Preferably, a resisting spring is connected between the side outer wall of the sliding member and the side inner wall of the mounting ring.
[0012] The beneficial effects of the utility model are:
[0013] 1. When the rotatably mounted RF coaxial connector is in use, the installation ring, the sliding part and the resistance spring are set, and the characteristic of the spring generating a reaction force synchronously under the extrusion force is utilized, so that when in use, the device can automatically utilize the reaction force of the spring to push the sliding part to resist the outer wall of the docking harness. It is noted here that the outer wall of the harness here refers to the harness that has been inserted into the connector and the shell has been stripped. Therefore, by limiting the design of the center position of the docking harness, the pin can be always centered, thereby avoiding the phenomenon of the pin position deviation caused by excessive docking of the connector, ensuring the concentricity of the inner and outer conductors in the center position, thereby ensuring the normal use of the subsequent connector. The overall structural design is ingenious and has good practical effect.
[0014] 2. When the rotatably mounted RF coaxial connector is in use, the first limiting ring, the abutting clamp ring, the second limiting ring and the abutting clamp groove are arranged, and the linkage effect of the installation process of the male connector and the female connector is utilized to automatically drive the abutting clamp ring to engage with the inside of the abutting clamp groove, thereby reinforcing and locking the docking part of the male connector and the female connector, making it difficult for the male connector and the female connector to loosen and fall off during use, and the overall stability performance is excellent and the practical effect is good.

The first limiting ring 41 is provided on the side outer wall of the docking ring 31 located at the edge, and the contact snap ring 42 is provided on the side outer wall of the first limiting ring 41. The second limiting ring 43 is provided on the side outer wall of the female connector body 2 located at the edge. The second limiting ring 43 is located on one side outer wall of the first limiting ring 41 and is provided with a contact slot 44. The contact snap ring 42 and the contact slot 44 are snap-fitted. When the male connector body 1 and the female connector body 2 are docked and installed, the first limiting ring 41 will gradually approach the second limiting ring 43 as the installation process of the two is carried out. When the male connector body 1 and the female connector body 2 are installed, the contact snap ring 42 is completely inserted into the inside of the contact slot 44, thereby achieving the effect of automatic locking.

When the male connector body 1 and the female connector body 2 are installed After the installation is completed, the resistance ring 42 is completely inserted into the resistance groove 44, thereby achieving the effect of automatic locking; when the male connector body 1 is inserted into the docking wiring harness, when the wiring harness passes through the sliding member 53, the sliding member 53 is automatically driven by the moving squeezing resistance force of the wiring harness to contract the resistance spring 54 and then synchronously drives the sliding member 53 to contract toward the inside of the mounting ring 52. When the wiring harness is adjusted to a suitable position, the resistance spring 54 is automatically pushed out by the squeezing force of the wiring harness, and then the sliding member 53 pops out automatically when it pops out. Then, the sliding member 53 automatically fits the outside of the wiring harness when it pops out. By designing multiple sets of sliding members 53, the effect of centering the docking wiring harness is achieved.
