[0008] The locking rod moves linearly within the cavity via an arc-shaped protrusion connected to a limiting plate.

[0009] Preferably, the length of the cavity is greater than the height of the arc-shaped protrusion, so that the arc-shaped protrusion can be accommodated in the cavity.

[0010] Preferably, a return spring is provided inside the cavity, and the return spring is located on the outer periphery of the locking rod so that the return spring can move elastically inside the cavity.

[0011] Preferably, the limiting plate is provided with a pull plate for lifting, and a groove is provided in the middle of the pull plate.

[0012] Preferably, the tail end of the connecting groove is provided with a positioning groove for engaging the arc-shaped protrusion, and the positioning groove and the arc-shaped protrusion cooperate with each other.

[0029] To address the cumbersome and time-consuming connection and disconnection process of traditional RF coaxial connectors, which hinders rapid deployment and maintenance, this invention provides a quick-plug RF coaxial connector. The technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0030] Please see Figures 1-5 This utility model provides a quick-plug RF coaxial connector, including a male connector 1 and a female connector 2. The male connector 1 has a connector 3 on its outer periphery, and the female connector 2 has connecting grooves 4 on both sides of its outer periphery. The connector 3 and the connecting grooves 4 cooperate with each other.

[0031] The connector 3 includes guide rods 308 located on both sides of the male connector 1. A connecting sleeve 301 is slidably connected to the outer side of each guide rod 308. Holes 302 are formed on both sides of the connecting sleeve 301. A locking rod 303 is slidably connected inside each hole 302. An arc-shaped protrusion 304 is provided at the front end of the locking rod 303. A limiting plate 305 is provided at the end of the locking rod 303 away from the arc-shaped protrusion 304. The length of the hole 302 is greater than the height of the arc-shaped protrusion 304, so that the arc-shaped protrusion 304 can be accommodated within the hole 302. A return spring 306 is provided inside the hole 302, located on the outer periphery of the locking rod 303, allowing the return spring 306 to move elastically within the hole 302. A pull plate 307 for lifting is provided at the limiting plate 305, and a groove 3071 is provided in the middle of the pull plate 307.

[0032] The locking rod 303 is connected to the arc-shaped protrusion 304 inside the cavity 302 via the limiting plate 305, and moves linearly.

[0033] The connecting groove 4 has a positioning groove 5 at its tail end for engaging the arc-shaped protrusion 304, and the positioning groove 5 and the arc-shaped protrusion 304 cooperate with each other. The length of the connecting groove 4 matches the length of the arc-shaped protrusion 304 at the connecting sleeve 301, so that the arc-shaped protrusion 304 can move through the connecting sleeve 301 to the positioning groove 5 at the tail end of the connecting groove 4. The depth of the connecting groove 4 is less than the height of the arc-shaped protrusion 304, so that the arc-shaped protrusion 304 can be engaged with the positioning groove 5 through the connecting groove 4.

[0034] The male connector 1 is connected to the female connector 2 via a connector 3 by snapping it into the connecting groove 4 on the outer periphery of the female connector 2.

[0035] A rubber pad 6 is provided at the connection end of the female head 2.

[0036] The working principle of the quick-plug RF coaxial connector provided by this utility model is as follows:

[0037] When using, align male connector 1 with female connector 2, ensuring that their axes are aligned.

[0038] Hold the male end 1 and align the arc-shaped protrusion 304 of the connector 3 with the connecting groove 4 of the female end 2.

[0039] Gently push the male head 1 into the female head 2. The female head 2 compresses the return spring 306 through the arc-shaped protrusion 304. The return spring 306 contracts under force, and the arc-shaped protrusion 304 is housed in the cavity 302. Then push the male head 1 until the arc-shaped protrusion 304 is fully inserted into the connecting groove 4 and reaches the positioning groove 5.

[0040] When the arc-shaped protrusion 304 reaches the positioning groove 5, the return spring 306 elastically elongates, bringing the arc-shaped protrusion 304 into contact with the inside of the positioning groove 5. Through the connecting and obstructing effect between the arc-shaped protrusion 304 and the positioning groove 5, the male head 1 and the female head 2 are locked together.

[0041] During the process, the male head 1 and the female head 2 are squeezed against each other, causing the rubber pad 6 to deform under force and fill the gap between them, thus improving their sealing performance.

[0042] To disconnect, grasp the pull plate 307 and apply force through the slot 3071 to make the locking rod 303 overcome the elastic force of the return spring 306 and move backward.

[0043] When the locking lever 303 moves, the arc-shaped protrusion 304 will exit from the positioning groove 5.

[0044] After the locking rod 303 is fully retracted into the cavity 302, gently pull the male head 1 out of the female head 2 to disconnect the two.

[0045] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
