Description

Technical Field

[0001] This application relates to the field of radio frequency switch connector technology, and more specifically, to a quick-connect assembly and an electromechanical radio frequency coaxial switch. Background Technology

[0002] An electromechanical RF coaxial switch is an RF switch that controls the transmission path of RF signals by closing and opening mechanical contacts. Electromechanical RF coaxial switches are mainly used in communication base stations, test and measurement, and other fields.

[0003] Especially in the field of test and measurement, because electromechanical RF coaxial switches have multiple threaded interfaces, multiple threaded connection installations and disconnections of connecting wires are required during test and measurement. The slow speed of installation and disconnection results in a lot of time being spent on connecting wires before and after measurement, which affects the overall test and measurement speed. Utility Model Content

[0004] To overcome the above shortcomings, this application provides a quick-connect component and an electromechanical RF coaxial switch, which aims to improve the problem that the connection wires need to be installed and removed multiple times during testing and measurement, resulting in slow connection speed and long time consumption before and after measurement.

[0005] This application provides a quick-connect assembly, including a connector, a movable locking part, and an RF cable.

[0006] The connector includes a mating connector, a retaining ring, and locking claws. The retaining ring is integrally formed and sleeved on the outside of the mating connector. Multiple locking claws are offset outwards in a ring array at the front end of the mating connector, with gaps between adjacent locking claws. The inner sides of multiple sets of locking claws are provided with threads that mate with the RF switch interface, and the outer sides of the locking claws are provided with wedge-shaped grooves extending to the outside of the mating connector. The movable locking part includes a movable ring, a wedge block, and a spring. The movable ring is movably sleeved on the outside of the mating connector located in front of the retaining ring. The wedge block is fixed to the movable ring and slides in contact with the wedge groove. The wedge block gradually decreases in size from its front end to its rear end. The spring elastically supports the movable ring and the retaining ring. The RF cable is connected to the rear end of the connector.

[0007] Preferably, a groove is provided on the outer side of the connector, and a slider that slides in cooperation with the groove is fixedly provided on the inner side of the movable ring.

[0008] Preferably, the spring is disposed inside the groove, and one end of the spring abuts against the supporting slider.

[0009] Preferably, a limit rod is fixed to the side of the slider near the fixed ring, and one end of the spring is sleeved on the outside of the limit rod.

[0010] Preferably, one side of the fixing ring is provided with a groove that communicates with the sliding groove, and the other end of the spring is inserted into the groove.

[0011] Preferably, the outer side of the connection between the claw and the connector is provided with an annular groove, and the groove has a V-shaped cross-section.

[0012] Preferably, the depth of the groove at the junction of the groove and the wedge groove is lower than the depth of the wedge groove.

[0013] This application also provides an electromechanical radio frequency coaxial switch, including the quick-connect assembly described above and a radio frequency coaxial switch body. The connector and the movable locking part are fitted and installed with the threaded interface at the end of the radio frequency coaxial switch body.

[0014] Beneficial Effects: This application provides a quick-connect assembly and an electromechanical RF coaxial switch. The movable ring and wedge block slide backward along the connector. The claws at the front end of the movable ring return to their original outward offset state. After inserting multiple sets of claws into the threaded interface, the tension on the movable ring is released. Under the action of the spring force, the movable ring is squeezed, causing the wedge block to move forward automatically. The front end of the wedge block gradually enters the wedge groove, squeezing the claws. Rotating the connector causes the claws to rotate, achieving a quick and tight screw-in engagement between the claws and the RF switch connection thread, allowing for rapid connection of the connecting wires. When disconnecting the connecting wires, pulling the movable ring backward releases the pressure of the wedge block on the claws, causing the claws to tilt outward and expand, allowing for quick removal of the connector.

[0018] The technical solutions in the embodiments of this application will now be described with reference to the accompanying drawings.

[0019] Please see Figures 1-4 This application provides a quick-connect assembly, including a connector 1, a movable locking part 2, and an RF cable 3.

[0020] The connector 1 includes a connector 11, a retaining ring 12, and claws 13. The retaining ring 12 is integrally formed and sleeved on the outside of the connector 11. Multiple claws 13 are offset outward and arranged in a ring array at the front end of the connector 11, with gaps between adjacent claws 13. The inner sides of the multiple sets of claws 13 are provided with threads that mate with the RF switch interface. The outward tilt angle of the claws 13 is between 3° and 6°. The outer side of the claws 13 is provided with a wedge-shaped groove 14 extending to the outside of the connector 11. The movable clamping part 2 includes a movable ring 21, a wedge block 22, and a spring 23. The movable ring 21 is movably sleeved on the outside of the connector 11 located in front of the retaining ring 12. The wedge block 22 is fixed to the movable ring 21 and slides in engagement with the wedge groove 14. The wedge block 22 is gradually reduced in size from its front end to its rear end. The slope of the inclined surface of the wedge block 22 is greater than the slope of the wedge groove 14. The spring 23 elastically supports the movable ring 21 and the retaining ring 12. Radio frequency cable 3 is connected to the tail end of connector 1.

[0021] During connection, hold the quick-connect assembly and slide the movable ring 21 backward along the connector 11. Simultaneously, the wedge block 22 slides backward along the wedge groove 14, and the spring 23 is compressed. At this time, the claws 13 at the front end of the movable ring 21 return to their original outward offset state, meaning the gap between the multiple sets of claws 13 is larger than the diameter of the RF switch threaded interface. After inserting the multiple sets of claws 13 outside the threaded interface, the tension on the movable ring 21 is released. Under the elastic force of the spring 23, the movable ring 21 is squeezed, causing the wedge block 22 to move forward automatically. The front end of the wedge block 22 gradually enters the wedge groove 14, squeezing the claws 13. Rotating the connector 11 then rotates the claws 13, allowing for a quick and tight screw-in engagement between the claws 13 and the RF switch connection thread, enabling rapid connection of the connector wires. When disconnecting the connector wires, pull the movable ring 21 backward to release the pressure of the wedge block 22 on the claws 13. The claws 13 tilt outward and expand, allowing the connector to be quickly pulled out. Compared to traditional screw-in installation methods, this quick-connect assembly enables rapid connection and disassembly of interfaces, significantly improving the speed of test and measurement connector assembly and disassembly.

[0022] In the above specific embodiment, a groove 15 is provided on the outer side of the connector 11, and a slider 24 that slides in cooperation with the groove 15 is fixedly provided on the inner side of the movable ring 21. The groove 15 and the slider 24 are provided to further improve the stability of the movable ring 21 when it moves. A spring 23 is provided inside the groove 15, and one end of the spring 23 is tightly pressed against the supporting slider 24. This arrangement reduces the exposed area of ​​the spring 23 and provides good protection for the spring 23.

[0023] Furthermore, a limiting rod 25 is fixed to the side of the slider 24 near the fixed ring 12, and one end of the spring 23 is sleeved on the outside of the limiting rod 25. A groove 17 communicating with the slide groove 15 is provided on one side of the fixed ring 12, and the other end of the spring 23 is inserted into the groove 17. The limiting rod 25 and the groove 17 are both provided to limit the stable contraction and relaxation of the spring 23.

[0024] In the specific design, a ring-shaped groove 16 is provided on the outer side of the connection between the claw 13 and the connector 11, and the groove 16 has a V-shaped cross-section. This design makes it easier for the claw 13 to tilt outward and reduces material fatigue at the connection between the claw 13 and the connector 11.

[0025] Furthermore, at the junction of the groove 16 and the wedge groove 14, the depth of the groove 16 is lower than the depth of the wedge groove 14. This keeps the wedge block 22 stable within the wedge groove 14.

[0026] This application also provides an electromechanical radio frequency coaxial switch including the aforementioned quick-connect assembly and a radio frequency coaxial switch body 4. The connector 1 and the movable locking part 2 are fitted and installed by mating with the threaded interface at the end of the radio frequency coaxial switch body 4.

[0027] The working principle of this quick-connect assembly and electromechanical RF coaxial switch is as follows: During use, hold the quick-connect assembly and slide the movable ring 21 backward along the connector 11. Simultaneously, the wedge block 22 slides backward along the wedge groove 14, and the spring 23 is compressed. At this time, the claws 13 at the front end of the movable ring 21 return to their original outward offset state, meaning the gap between the multiple sets of claws 13 is greater than the diameter of the RF switch threaded interface. After inserting the multiple sets of claws 13 into the outside of the threaded interface, the tension on the movable ring 21 is released. Under the elastic force of the spring 23, the movable ring 21 is squeezed, causing the wedge block 22 to move automatically forward. At this time, the front end of the wedge block 22 gradually enters the wedge groove 14, squeezing the claws 13. Rotating the connector 11 then rotates the claws 13, enabling a quick and tight screw-in engagement between the claws 13 and the RF switch connection thread, thus achieving rapid connection of the connecting wires. When disconnecting the connector, pull the movable ring 21 backward to release the pressure of the wedge block 22 on the claw 13. The claw 13 tilts outward and expands, allowing the connector to be pulled out quickly.

Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
