[0002] A radio frequency coaxial connector is a key component for transmitting radio frequency signals and is widely used in wireless communication, radar, data transmission, aerospace and other fields. The basic structure of a radio frequency coaxial connector includes a center conductor, an insulator and an outer contact, which is usually made of metal material and has good shielding performance and anti-interference ability.

[0050] It should be noted that, since the plug pin rod 24 is connected with the lifting rod 20, the lifting distance of the bottom of the plug pin rod 24 when separating from the convex ring at the front end of the insertion rod 25 is the same as the distance of the limiting block 21 when rising to the same horizontal plane as the axis of the insertion rod 25.

[0051] The above embodiments are exemplary but not restrictive, and therefore the technical scheme of the utility model can be realized in other specific forms without departing from the spirit or basic characteristics of the utility model, which is included in the utility model.
