[0019] like Figures 1 to 6 As shown, the utility model provides a technical solution: a coaxial radio frequency connector with a fastened connection, comprising a female head 1 and a male head 2, wherein the connecting end of the male head 2 is provided with a mounting ring 3, the outer wall of the mounting ring 3 is provided with an external thread, a limiting hole is provided on the mounting ring 3, the axis of the limiting hole is perpendicular to the axis of the mounting ring 3, in other words, the limiting hole extends along the outside of the mounting ring 3 toward the axis of the mounting ring 3, the connecting end of the female head 1 is rotatably installed with a rotating ring 4, the inner wall of the rotating ring 4 is provided with an internal thread, the male head 2 and the female head 1 are connected by the external thread on the mounting ring 3 and the rotating ring 4 is provided with an internal thread, The internal threads on the rotating ring 4 are threadedly connected to each other, so as to limit the plug-in position of the female head 1 and the male head 2, and avoid the loosening of the plug-in connection between the female head 1 and the male head 2 during use. The side wall of the rotating ring 4 is provided with a mounting portion 5, and a limiting component 6 is installed in the mounting portion 5. After the female head 1 and the male head 2 are plugged into each other, the limiting component 6 is operatively inserted into the limiting hole to further limit the rotating ring 4. Even in the previous use process, it can effectively avoid the mutual loosening of the mounting ring 3 and the rotating ring 4, and the problem of loosening of the connection between the male head 2 and the female head 1 can be avoided, thereby ensuring the normal use of the connector.

[0020] In a further embodiment, the mounting portion 5 includes a cylindrical hole 51, which extends outward along the inner wall of the rotating ring 4. A connecting hole 52 is provided on the outer wall of the rotating ring 4. The connecting hole 52 is connected to the cylindrical hole 51 and axially overlaps with each other. The diameter of the connecting hole 52 is smaller than the diameter of the cylindrical hole 51. When the cylindrical hole 51 overlaps with the limiting hole, the axis of the cylindrical hole 51 overlaps with the axis of the limiting hole. A rectangular groove 53 is further provided in the side wall of the rotating ring 4. One end of the rectangular groove 53 is connected to the cylindrical hole 51. The length direction of the rectangular groove 53 is parallel to the axis of the rotating ring 4. A sliding groove 54 is provided on the outer wall of the cylindrical hole 51. The sliding groove 54 is connected to the rectangular groove 53. The length of the slide groove 54 is the same as the length of the rectangular groove 53, and the width of the slide groove 54 is smaller than the width of the rectangular groove 53. The limit assembly 6 includes a first movable column 61, and a second mounting ring 62 is installed at the bottom of the first movable column 61. The first movable column 61 and the second mounting ring 62 reciprocate in the cylindrical hole 51, wherein the sum of the heights of the first movable column 61 and the second mounting ring 62 is the same as the height of the rectangular groove 53. A mounting groove 63 is provided in the first movable column 61, and a second movable column 64 is placed above the first movable column 61. One end of the second movable column 64 is slidably installed in the mounting groove 63. The first movable column 61 and the second movable column 64 are made of PVC material. The second movable column 64 is slidably mounted with a second mounting ring 65, a spring 66 is installed between the second mounting ring 62 and the second mounting ring 65, and the second mounting ring 62 is connected to the second mounting ring 65 by the spring 66. The outer diameters of the second mounting ring 62 and the second mounting ring 65 are the same as the diameter of the cylindrical hole 51, and a limiting plate 67 is installed on the top of the second movable column 64. The diameter of the limiting plate 67 is larger than the diameter of the connecting hole 52, that is, after the male head 2 and the female head 1 are plugged into each other, the rotating ring 4 and the mounting ring 3 are in a state of being away from each other, and a part of the limiting component 6 is located in the rectangular groove 53 of the mounting portion 5, and an external force is applied to the rotating ring 4, so that the rotating ring 4 is meshed and connected to the mounting ring 3. After the rotating ring 4 rotates into the mounting ring 3 and reaches the limit position, the cylindrical hole 51 in the mounting portion 5 and the limit hole on the mounting ring 3 are on the same axis, and an external force is applied to the limit assembly 6 to move the limit assembly 6 toward the cylindrical hole 51 until it moves above the cylindrical hole 51. At this time, under the action of the spring 66, the first movable column 61 is driven to slide into the cylindrical hole 51. During this process, the second movable column 64 slides in the mounting groove 63 of the first movable column 61, that is, the overlapping part of the second movable column 64 and the first movable column 61 is reduced, so that the total length of the first movable column 61 and the second movable column 64 becomes longer, that is, the first movable column 61 is inserted into the limit hole under the action of the spring 66, so as to realize the mutual limitation of the rotating ring 4 and the mounting ring 3.

[0021] When the female head 1 and the male head 2 need to be disassembled from each other, an external force is applied to the second movable column 64 to make the second movable column 64 move axially outward along the cylindrical hole 51. With the cooperation of the cylindrical hole 51, the second mounting ring 62 and the second mounting ring 65, the spring 66 is compressed to make the first movable column 61 disengage from the limiting hole. When the spring 66 reaches the compression limit, the first movable column 61 is moved to the rectangular groove 53 and the applied force is cancelled. At this time, the rotating ring 4 can be rotated to make the rotating ring 4 and the mounting ring 3 disengage from each other, thereby realizing the mutual disengagement of the female head 1 and the male head 2.

[0022] The preferred embodiments of the present invention are described in detail above. However, the present invention is not limited to the specific details in the above embodiments. Within the technical concept of the present invention, various equivalent transformations can be made to the technical scheme of the present invention, and these equivalent transformations all belong to the protection scope of the present invention.
