As a component for electrically connecting or separating a transmission line, it belongs to a mechatronics product. Simply put, it mainly plays a bridging role. There is an existing patent for a rotatable curved radio frequency coaxial connector, patent publication number CN220710792U, which includes an inner conductor, an insulator, a first shell, a second shell, a flange, an insulating sheet, and a back cover. An insulator is fixedly installed inside the first shell, and an inner conductor is fixedly installed inside the insulator.

The outer shell of the curved radio frequency coaxial connector of the utility model is provided with barbs, and the insulator and the center contact will not move left and right.

[0003] With respect to the above-mentioned related technologies, the inventors believe that the following defects exist: in the above-mentioned applications, although the connector can be installed in any direction during use, in actual application, since the coaxial RF connector is mostly located at the rear of the device during the connection process, the rear space is small, and it is inconvenient to check during the connection and installation process, which makes the installation and positioning difficult and affects the subsequent disassembly and assembly operations. Therefore, we propose a rotatable curved RF coaxial connector to solve the above-mentioned problems. Utility Model Content
