[0002] A multi-interface RF coaxial connector is an RF transmission device with multiple connection ports, enabling efficient and reliable signal transmission and distribution between multiple RF signal paths. It typically consists of multiple coaxial interfaces interconnected through internal circuitry, supporting the input and output of various RF signals. It is widely used in communication base stations, radar systems, test equipment, and other scenarios to achieve signal distribution, combining, and splitting functions. It also possesses excellent electrical performance and mechanical stability, ensuring the integrity and reliability of signal transmission.

[0003] Traditional RF coaxial connectors mostly adopt an integrated fixed structure. This design has obvious drawbacks in multi-interface RF coaxial connectors. Once any one of the RF coaxial connectors is damaged, the damaged part cannot be replaced individually. Instead, the entire connector must be disassembled to maintain the specified RF coaxial connector. This method is not only cumbersome to operate, but also easily causes other RF coaxial connectors to loosen, increasing the difficulty of installation. Therefore, a detachable multi-interface RF coaxial connector is proposed to address the above problems. Utility Model Content

[0026] Please see Figures 1-6 This utility model provides a technical solution:

[0027] A detachable multi-interface radio frequency coaxial connector includes a radio frequency coaxial connector assembly 1. An auxiliary fixing assembly 2 and a pre-tightening fixing assembly 3 are installed on the outside of the radio frequency coaxial connector assembly 1. The radio frequency coaxial connector assembly 1 includes a radio frequency coaxial connector body 12. A retaining shell 13 and a protruding ring 15 are fixedly connected to the outside of the radio frequency coaxial connector body 12. An assembly groove 14 is opened on the inside of the retaining shell 13. The auxiliary fixing assembly 2 includes a first plate base 21. A front block 23 is fixedly connected to the front end of the first plate base 21. A socket 25 is opened on the inside of the first plate base 21. The pre-tightening fixing assembly 3 includes a second plate base 31. A spring telescopic rod 33 is fixedly connected to the front end of the second plate base 31. An arched sleeve 34 is fixedly connected to the front end of the spring telescopic rod 33. A crimping groove 35 is opened on the inside of the arched sleeve 34. An anti-disengagement rod 36 is fixedly connected to the rear end of the arched sleeve 34. The anti-disengagement rod 36 is inserted into the inside of the socket 25.

[0028] As a further implementation of this solution, a threaded strip 16 is fixedly connected to the outside of the RF coaxial connector body 12. The threaded strip 16 is screwed together with the crimp nut 11. The rear end of the crimp nut 11 is tightly attached to the front end of the arched housing 34. A deformable pressure plate 17 is fixedly connected to the front end of the RF coaxial connector body 12. Through the above settings, the connection between the crimp nut 11 and the threaded strip 16 is more secure, and it is easy to quickly disassemble and install, improving maintenance efficiency. The tight fit between the rear end of the crimp nut 11 and the front end of the arched housing 34 enhances the stability of the structure and ensures the reliability of the connection.

[0029] As a further implementation of this solution, the upper end of the first plate base 21 is provided with a first arc-shaped groove 22. There are multiple first plate bases 21. The inner side of the first arc-shaped groove 22 fits against the outer side of the RF coaxial connector body 12. Through the above arrangement, the design of multiple first plate bases 21 enables the device to support the installation of multiple RF coaxial connectors, thereby improving the multifunctionality and expandability of the device.

[0030] As a further implementation of this solution, the front end of the front block 23 is provided with an arc groove 24. The arc groove 24 has an arc-shaped structure. The front end of the front block 23 is inserted into the inner side of the assembly slot 14. Through the above setting, the arc groove 24 with an arc-shaped structure allows the front end of the front block 23 to be inserted into the inner side of the assembly slot 14 more smoothly, reducing friction and resistance during insertion and improving assembly efficiency.

[0031] As a further implementation of this solution, a guide hole 26 is provided at the upper end of the first plate base 21, and an insertion hole 25 is provided on the inner side of the first plate base 21. A guide rod 37 is inserted into the guide hole 26, and an anti-disengagement rod 36 is inserted into the insertion hole 25. Through the above settings, the rapid positioning and fixing between the first plate base 21 and the second plate base 31 are realized, which improves the accuracy and efficiency of assembly. This design also provides a basis for subsequent locking and enhances the connection strength between components.

[0032] As a further implementation of this solution, a second arc-shaped groove 32 is provided at the lower end of the second plate base 31. The inner side of the second arc-shaped groove 32 fits against the outer side of the RF coaxial connector body 12. The arched sleeve 34 is sleeved on the outer side of the convex ring 15 through the crimping groove 35. The lower end of the arched sleeve 34 extends to the lower end of the crimping nut 11. Through the above arrangement, the stability of the structure is enhanced, the compactness and stability of the overall structure are further improved, and the risk of component loosening is reduced.

[0033] Workflow: When assembling the device, the crimp nut 11 is pre-fitted onto the outside of the wire from the end of the wire. The wire is then connected to the RF coaxial connector body 12 through the deformable pressure plate 17. The retaining shell 13 of the RF coaxial connector body 12 is fixed downwards. At this time, under the elastic force of the spring telescopic rod 33, a certain gap can be formed between the arched sleeve 34 and the second plate seat 31. Simultaneously, through projection observation, the rear end of the anti-disengagement rod 36 is located at the front end of the second plate seat 31. The first arc-shaped groove 22 opened in the first plate seat 21 is fitted onto the outside of the RF coaxial connector body 12 and is located at the rear end of the convex ring 15. The front end of the front block 23 is aligned with the assembly groove 14. The shape of the arc groove 24 allows for... The protruding front end of the front block 23 and the shape of the arc groove 24 improve the convenience of vertical insertion of the front block 23 into the assembly groove 14. The cooperation between the retaining shell 13 and the front block 23 prevents the RF coaxial connector body 12 from twisting. After the first plate base 21 is installed with the corresponding RF coaxial connector body 12, the pre-assembled first plate base 21 and RF coaxial connector assembly 1 are moved to the lower end of the second plate base 31, so that the guide hole 26 and the guide rod 37 are aligned vertically, and the guide rod 37 is inserted into the guide hole 26. The setting of the guide rod 37 and the guide hole 26 not only guides the installation between the first plate base 21 and the second plate base 31, but also provides a basis for subsequent locking, until the second plate base 31 is installed. After the second arc-shaped groove 32 of the plate base 31 is fitted with the upper end of the RF coaxial connector body 12, the arched sleeve 34 is sleeved on the outside of the convex ring 15. The anti-disengagement rod 36 is located at the front end of the first plate base 21, and the anti-disengagement rod 36 is aligned with the socket 25. To fix the device, one hand fixes the second plate base 31, and the other hand rotates the crimp nut 11. Through the spiral engagement of the crimp nut 11 and the threaded strip 16, the crimp nut 11 presses against the deformable pressure plate 17, achieving the effect of fixing the circuit and the RF coaxial connector body 12. The crimp nut 11 pushes the front end of the arched sleeve 34, and the arched sleeve 34 presses against the spring telescopic rod 33. At the same time, the arched sleeve 34 drives the anti-disengagement rod 36 to move backward. The connector is inserted into the socket 25 to prevent detachment between the first plate holder 21 and the second plate holder 31. Together with the arched sleeve 34 and the front block 23, they form a clamping force on the convex ring 15 and the retaining shell 13, thereby securing the RF coaxial connector assembly 1, the auxiliary fixing assembly 2, and the pre-tightening fixing assembly 3. When maintaining a single RF coaxial connector body 12, simply rotate the corresponding crimp nut 11 to separate it from the threaded strip 16 and the deformable pressure plate 17. The spring force of the spring telescopic rod 33 causes the anti-detachment rod 36 to disengage from the socket 25. Then, the first plate holder 21 is moved downwards to disassemble and maintain the specified RF coaxial connector assembly 1. Similarly, when installing individual RF coaxial connector assemblies 1...The circuit and the RF coaxial connector body 12 can be secured simply by rotating the crimp nut 11, simultaneously securing the RF coaxial connector assembly 1 to the auxiliary fixing assembly 2 and the pre-tightening fixing assembly 3. This operation method eliminates the need for disassembly and replacement of the entire assembly.

[0034] 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.
