Technical Field

[0001] This utility model relates to the field of radio frequency coaxial connector technology, specifically a radio frequency coaxial connector with an anti-loosening structure. Background Technology

[0002] Radio frequency coaxial connectors (hereinafter referred to as RF connectors) are generally considered to be components that are attached to cables or installed on instruments. As components that electrically connect or disconnect transmission lines, they belong to mechatronics products, and simply put, they mainly act as bridges.

[0003] Upon investigation, a Chinese utility model patent discloses an RF coaxial connector with an anti-loosening structure (publication number: CN216450887U), which includes an anti-loosening component centrally disposed between a first connector body and a second connector body for fixing and connecting the RF coaxial connector. The first connector body includes a first connecting shaft disposed on the side near the second connector body, and the second connector body includes a second connecting shaft disposed on the side near the first connecting shaft.

[0004] In the aforementioned patent, the first connecting shaft and the second connecting shaft are connected by inserting a limiting block into the limiting groove. Then, the stability of the first connecting shaft and the second connecting shaft is improved by inserting the first anti-loosening insert plate and the second anti-loosening insert plate into the first and second mounting grooves in a staggered manner. This improves the anti-loosening and signal transmission capabilities of the overall device. However, during installation, after ensuring that the flange and the notch are engaged, the first fixing bolt is rotated to fix the insert block into the mounting notch. However, during disassembly, multiple fixing bolts need to be pulled out, making the disassembly process cumbersome.

[0005] Therefore, this utility model provides an RF coaxial connector with an anti-loosening structure to solve the above problems. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This utility model provides an RF coaxial connector with an anti-loosening structure, such as... Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the radio frequency coaxial connector with anti-loosening structure includes a first radio frequency connector 1, a first mounting frame 2 fixedly installed on one side of the first radio frequency connector 1, a first connecting shaft 3 fixedly installed on one side of the first mounting frame 2, a second radio frequency connector 4 disposed on one side of the first connecting shaft 3, a second mounting frame 5 fixedly installed on one side of the second radio frequency connector 4, a second connecting shaft 6 fixedly installed on one side of the second mounting frame 5, and a loading and unloading mechanism disposed between the first connecting shaft 3 and the second connecting shaft 6 for easy installation and disassembly.

[0027] The loading and unloading mechanism includes a fixed rod 7 fixedly installed inside the second connecting shaft 6, a threaded rod 8 slidably installed on the fixed rod 7, a rotating block 9 rotatably installed on the second connecting shaft 6, an annular insert 10 fixedly installed on one side of the rotating block 9, an annular groove opened inside the first connecting shaft 3 for the annular insert 10 to be inserted into, a fixed cylinder 11 fixedly connected inside the annular groove, a sliding groove 12 opened inside the fixed cylinder 11, and a slider 13 slidably installed inside the sliding groove 12.

[0028] Multiple fixed rods 7 are provided, and the fixed rods 7 are arranged in a ring array inside the second connecting shaft 6. The threaded rod 8 is screwed into the rotating block 9. Multiple sliding grooves 12 are provided, and the sliding grooves 12 are arranged in a ring array inside the fixed cylinder 11. The annular insert block 10 has an inclined groove for the slider 13 to be inserted into.

[0029] In use, this RF coaxial connector with an anti-loosening structure is first inserted into the first connecting shaft 3, with the second connecting shaft 6 facing it, until the annular insert 10 is fully inserted into the annular groove. The fixing cylinder 11 is inside the annular insert 10. Then, the rotating block 9 is rotated. Through the rotation of the rotating block 9 and the cooperation between the multiple fixing rods 7, the threaded rod 8 moves along the fixing rod 7 towards the first connecting shaft 3. The threaded rod 8 first contacts the inclined surface of the multiple sliders 13, thereby pressing the multiple sliders 13 outward until the multiple sliders 13 are inserted into the inclined groove inside the annular insert 10, thus completing the fixation between the first connecting shaft 3 and the second connecting shaft 6. When it is necessary to disassemble the first connecting shaft 3 and the second connecting shaft 6, simply rotate the rotating block 9 in the opposite direction. The threaded rod 8 moves away from the first connecting shaft 3 along the fixed rod 7, and moves out of the annular groove, releasing the fixation of the annular insert 10. This allows the second connecting shaft 6 to be pulled out from the inside of the first connecting shaft 3, thus completing the disassembly of the first connecting shaft 3 and the second connecting shaft 6. The whole process is convenient and can be installed and disassembled without the aid of tools, reducing the difficulty of operation. At the same time, the RF coaxial connector, through the set loading and unloading mechanism, not only realizes the quick installation and disassembly between the first connecting shaft 3 and the second connecting shaft 6, but also increases the stability of the connection between the first connecting shaft 3 and the second connecting shaft 6 through the cooperation between multiple sliders 13 and the inclined groove, avoiding the loosening of the RF coaxial connector during use and improving the practicality of the RF coaxial connector.

[0030] Furthermore, to facilitate the disassembly of the first connecting shaft 3 and the second connecting shaft 6, such as... Figure 1 , Figure 2 and Figure 3 As shown, a fixing block 14 is fixedly connected to one side of the slider 13, and a spring 15 is provided inside the slide groove 12.

[0031] One end of the spring 15 is fixedly connected to one side of the fixed block 14, and the other end of the spring 15 is fixedly connected to one side of the slide groove 12.

[0032] When using this RF coaxial connector with an anti-loosening structure, if it is necessary to disassemble the first connecting shaft 3 and the second connecting shaft 6, the rotating block 9 is rotated in the opposite direction. Through the reverse rotation of the rotating block 9, the threaded rod 8 moves away from the first connecting shaft 3 along the fixed rod 7. The threaded rod 8 moves out of the inside of the annular groove. At this time, through the cooperation between the spring 15 and the fixed block 14, the slider 13 is pulled out from the inside of the inclined groove. At this time, the limit on the annular insert 10 is released, and the second connecting shaft 6 can be pulled out from the inside of the first connecting shaft 3, thereby completing the disassembly between the first connecting shaft 3 and the second connecting shaft 6. The whole process is convenient to operate and further improves the practicality of the RF coaxial connector.

[0033] It should be noted that, in order to improve the anti-loosening performance of this RF coaxial connector, such as... Figure 1 , Figure 2 and Figure 3 As shown, a first connecting block 16 is fixedly connected to one side of the second connecting shaft 6, and a snap-fit ​​protrusion 17 is fixedly connected to the side surface of the first connecting block 16.

[0034] A second connecting block 18 is fixedly connected to one side of the first connecting shaft 3. The second connecting block 18 has a snap-fit ​​groove 19 inside for snap-fit ​​protrusion 17 to snap into.

[0035] When the first connecting shaft 3 and the second connecting shaft 6 are connected, the locking engagement between the locking protrusion 17 and the locking groove 19 ensures a tighter connection, improving the anti-loosening performance of the RF coaxial connector. Simultaneously, the rotation of the rotating block 9 allows for easy disassembly and installation of the first connecting shaft 3 and the second connecting shaft 6, further enhancing the practicality and convenience of the RF coaxial connector.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
