Description

Technical Field

[0001] This invention specifically relates to a radio frequency connector interface positioning structure and its usage method. Background Technology

[0002] Radio frequency (RF) connectors are key components for transmitting RF signals in fields such as wireless communication, radar systems, aerospace, and consumer electronics. Their main function is to provide a detachable electrical connection between transmission lines and ensure impedance matching and low loss during signal transmission. With the rapid development of electronic devices towards miniaturization, high density, and modularity, the number of RF connectors used is increasing daily, and installation space is becoming increasingly limited, placing ever higher demands on the connector's mating accuracy and positioning reliability.

[0003] Currently, conventional RF connector interface positioning methods are mainly divided into two categories. One type relies on threaded engagement for locking, using only the natural guidance of the inner and outer conductor cylindrical surfaces, without an independent circumferential positioning structure. The other type uses a single keyway positioning structure to achieve circumferential limiting. RF connectors without an independent positioning structure lack guidance and limiting during insertion, making the male and female interfaces prone to radial offset and angular deviation, causing misalignment of the inner conductors, resulting in impedance discontinuity and increased signal reflection under high-frequency conditions. Under vibration conditions, the interface is prone to relative rotation, loosening of the contact interface, leading to deterioration of passive intermodulation and intermittent connection failure. Furthermore, they cannot prevent mistaken insertion, making them highly susceptible to incorrect installation or reverse insertion, causing permanent deformation and damage to the contacts.

[0004] Traditional single-keyway positioning structures only have a single positioning protrusion and positioning groove, resulting in a narrow guiding range, low insertion fault tolerance, and high alignment difficulty in blind insertion scenarios. During the insertion and removal process, the positioning protrusion experiences local stress concentration, and after repeated insertion and removal, the positioning protrusion is prone to wear and breakage, resulting in loss of positioning accuracy. Furthermore, single-key positioning can only limit a single circumferential angle, which cannot adapt to the multi-angle assembly requirements of multi-phase and multi-channel RF interfaces.

[0005] Most existing positioning structures place the positioning boss directly on the mating surface of the connector's outer conductor. The positioning surface is coupled with the RF shielding mating surface. Metal debris generated by positioning wear falls between the inner and outer conductors, which can easily cause short circuits and poor contact. At the same time, the positioning structure is integrated with the connector housing. Once the positioning structure is damaged, the entire connector needs to be replaced, resulting in high maintenance costs.

[0006] Therefore, it is necessary to invent a radio frequency connector interface positioning structure and usage method to solve the above problems. Summary of the Invention

[0007] (a) Purpose of the invention

[0008] The purpose of this invention is to provide a radio frequency connector interface positioning structure and its usage method.

[0009] (II) Technical Solution

[0010] To achieve the above objectives, the present invention provides the following technical solution: a radio frequency connector interface positioning structure, including a plug end and a socket end that are mutually matched by the radio frequency connector, wherein the plug end is provided with an inner conductor, and the socket end is provided with a socket that matches the inner conductor;

[0011] The outer wall of the plug end is provided with a plurality of evenly spaced mounting grooves. The outer wall of the plug end is also provided with a movable ring groove at the bottom of the plurality of mounting grooves. A plurality of positioning components are installed in the plurality of mounting grooves and the movable ring grooves. The plurality of positioning components assist the plug end in being inserted into the socket end.

[0012] The positioning component includes a movable ring disposed in the movable ring groove. The upper end of the movable ring is adapted to multiple mounting grooves and multiple guide plate assemblies are provided. The movement of the movable ring drives the multiple guide plate assemblies to move within the mounting grooves. The bottom of the mounting groove is also provided with a positioning protrusion assembly and an auxiliary spring block assembly. The positioning protrusion assembly positions the guide plate assembly within the mounting groove.

[0013] Preferably, the guide plate assembly includes a guide plate and a push plate. The guide plate is disposed at the top opening of the mounting groove. The push plate is connected to the tail of the guide plate, and its other end is connected to the top of the moving ring. Multiple push plates simultaneously push and pull the upper end corresponding to the guide plate. The top of the guide plate is provided with a rotating sleeve, and the bottom two sides are provided with rotating ears. The top opening of the mounting groove is provided with a fixed shaft adapted to the rotating sleeve. The top of the push plate is adapted to the rotating ear and is provided with a mating sleeve. The mating sleeve and the rotating ear are installed together with the rotating shaft. The bottom of the push plate is provided with a through hole. The top of the moving ring is provided with a mounting ear. The mounting ear and the through hole are installed together with a shaft. When the moving ring moves vertically, the push plate and the guide plate fold and move simultaneously.

[0014] Preferably, the guide plate is provided with a positioning hole, the positioning hole is adapted to the positioning protrusion assembly, the overall length of the push plate is sufficient to push the guide plate, and the guide plate forms an acute angle with the outer wall of the plug end. The rotating shaft and both ends of the shaft are provided with limiting structures, and the upper end of the push plate is set as an inclined surface on both sides of the docking sleeve.

[0015] Preferably, the lower inner side of the mounting groove is provided with a push-pull groove, and the connection part between the push-pull groove and the upper inner side of the mounting groove is set as an inclined surface. The positioning protrusion assembly and the auxiliary spring block assembly are both arranged on the upper inner side of the mounting groove.

[0016] Preferably, the positioning protrusion assembly includes a telescopic groove disposed inside the mounting groove, a positioning protrusion is installed in the telescopic groove, a spring is installed between the inner end of the positioning protrusion and the bottom of the telescopic groove, a limiting ring is provided at the end edge of the positioning protrusion, a limiting ring adapted to the limiting ring is provided at the opening of the telescopic groove, and the end of the positioning protrusion is tapered.

[0017] Preferably, the auxiliary spring block assembly includes an auxiliary lifting groove disposed inside the mounting groove and located below the positioning protrusion assembly. An auxiliary spring block is installed in the auxiliary lifting groove. An auxiliary lifting spring is installed between the end of the auxiliary spring block and the bottom of the auxiliary lifting groove. A limiting plate is provided at the edge of the end of the auxiliary spring block. A limiting strip adapted to the limiting plate is provided at the opening of the auxiliary lifting groove. The end of the auxiliary spring block abuts against the inside of the guide plate assembly.

[0018] Preferably, the outer wall of the movable ring is provided with a threaded structure that adapts to the inner wall of the socket end, and the installation position of the positioning component does not exceed the groove opening on the outer wall of the mounting groove.

[0019] Preferably, both the plug end and the socket end have anti-slip sections and rotating sections on their outer walls.

[0020] A method for using a radio frequency connector interface positioning structure includes:

[0021] S1. Grip and align the plug end and socket end by using the anti-slip section and rotating section on the outer wall to confirm that the positioning components in the mounting groove and moving ring groove on the outer wall of the plug end are in the initial storage state, the guide plate assembly is stored in the mounting groove and is limited and fixed by the positioning protrusion assembly and the auxiliary spring block assembly, and each component is in the pluggable working state.

[0022] S2. Push the moving ring in the moving ring groove upward axially. The moving ring drives the push plate to move through the mounting lug and shaft. The push plate pulls the guide plate to rotate and open around the fixed shaft through the rotating shaft, so that the guide plate and the outer wall of the plug end form an acute angle. After the guide plate is opened, the plug end can be positioned inside the socket end through the guide plate to achieve precise docking and positioning of the plug end and the socket end.

[0023] S3. After positioning, reset and push the moving ring to reset the guide plate and push plate into the mounting groove. Then rotate the plug end and use the threaded structure on the outer wall of the moving ring to lock it with the threaded engagement of the inner wall of the socket end, thus restricting the axial and circumferential loosening of the plug end and the socket end.

[0024] S4. If unlocking is required, rotate the plug end in the opposite direction to release the threaded lock of the moving ring, pull the moving ring axially down, and drive the push plate and guide plate to fold back and reset in the opposite direction; the guide plate squeezes the positioning protrusion to compress the spring and retract the hole, while pressing down the auxiliary spring block to compress the auxiliary lifting spring and retract it. The guide plate assembly is completely stored in the mounting groove. After the positioning constraint is released, the plug end and the socket end can be separated axially.

[0025] Compared with the prior art, the beneficial effects of the above-mentioned technical solution of the present invention are:

[0026] 1. Before insertion, the present invention uses a moving ring to link multiple sets of guide plate assemblies to expand outward synchronously. The guide plate forms an acute angle with the outer wall of the plug end, forming a ring-shaped guide and positioning structure around the plug. This can guide the plug end to be smoothly centered and inserted into the socket end, effectively correcting the radial offset and skew problems when the plug and socket are inserted, improving the coaxiality of the coaxial connection, and ensuring radio frequency electrical performance.

[0027] 2. The guide plate and push plate of the present invention can be completely housed inside the mounting groove on the outer wall of the plug end, and the outer contour of the positioning component does not exceed the groove on the outer wall of the plug; the connector has no extra protruding structure in its external dimensions, does not change the original installation space requirements of the connector, and can be adapted to conventional equipment installation cavities.

[0028] 3. This invention relies on the vertical movement of the moving ring to uniformly drive all guide plate components. All guide plates unfold and retract synchronously, and the circumferential positioning force is uniform, so there will be no phenomenon of one-sided guidance or uneven local force. The folding linkage mechanism is formed by multi-layer rotating shaft hinges, which makes the movement smooth, the unfolding and retraction actions stable, and it is not easy to get stuck.

[0042] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0043] This invention provides, for example Figure 1-10 The radio frequency connector interface positioning structure shown includes a plug end 1 and a socket end 2 that are mutually matched by the radio frequency connector. The plug end 1 is provided with an inner conductor 11, and the socket end 2 is provided with a socket 21 that matches the inner conductor 11.

[0044] The outer wall of the plug end 1 is provided with multiple evenly spaced mounting grooves 12. The outer wall of the plug end 1 is also provided with a movable ring groove 13 at the bottom of the multiple mounting grooves 12. Multiple positioning components 3 are installed in the multiple mounting grooves 12 and the movable ring groove 13. The multiple positioning components 3 assist the plug end 1 in being inserted into the socket end 2.

[0045] The positioning component 3 includes a movable ring 31 disposed in a movable ring groove 13. The upper end of the movable ring 31 is adapted to multiple mounting grooves 12 and multiple guide plate assemblies 32 are provided.

The bottom of the push plate 322 is provided with a through hole 328. The top of the moving ring 31 is provided with a mounting ear 35. The mounting ear 35 and the through hole 328 are installed together with a shaft 36. When the moving ring 31 moves vertically, the push plate 322 and the guide plate 321 fold and move simultaneously.

[0047] Specifically, the guide plate 321 is provided with a positioning hole 329, which is adapted to the positioning protrusion assembly 33. The overall length of the push plate 322 is sufficient to push the guide plate 321. The guide plate 321 forms an acute angle with the outer wall of the plug end 1. Both ends of the rotating shaft 237 and the shaft body 36 are provided with limiting structures. The upper end of the push plate 322 is set as an inclined surface on both sides of the docking sleeve 326.

[0048] Specifically, a push-pull groove 14 is provided on the inner side of the lower end of the mounting groove 12. The connection between the push-pull groove 14 and the inner side of the upper end of the mounting groove 12 is set as an inclined surface. The positioning protrusion assembly 33 and the auxiliary spring block assembly 34 are both provided on the inner side of the upper end of the mounting groove 12.

[0049] Specifically, the positioning protrusion assembly 33 includes a telescopic groove 331 disposed inside the mounting groove 12, a positioning protrusion 332 installed in the telescopic groove 331, a spring 333 installed between the inner end of the positioning protrusion 332 and the bottom of the telescopic groove 331, a limiting ring 334 provided at the end edge of the positioning protrusion 332, a limiting ring 335 adapted to the limiting ring 334 provided at the opening of the telescopic groove 331, and the end of the positioning protrusion 332 is tapered.

[0050] Specifically, the auxiliary spring block assembly 34 includes an auxiliary lifting groove 341 disposed inside the mounting groove 12 and located below the positioning protrusion assembly 33. An auxiliary spring block 342 is installed in the auxiliary lifting groove 341. An auxiliary lifting spring 343 is installed between the end of the auxiliary spring block 342 and the bottom of the auxiliary lifting groove 341. A limiting plate 344 is provided at the edge of the end of the auxiliary spring block 342. A limiting strip 345 adapted to the limiting plate 344 is provided at the opening of the auxiliary lifting groove 341. The end of the auxiliary spring block 342 rests against the inside of the guide plate assembly 33.

[0051] Specifically, the outer wall of the moving ring 31 is provided with a threaded structure that adapts to the inner wall of the socket end 2, and the installation position of the positioning component 3 does not exceed the groove opening on the outer wall of the mounting groove 12.

[0052] Specifically, both the plug end 1 and the socket end 2 are provided with anti-slip section 4 and rotating section 5 on their outer walls.

[0053] A method of using a radio frequency connector interface positioning structure includes:

[0054] S1. The anti-slip section 4 and rotating section 5 on the outer wall of the plug end 1 and socket end 2 are gripped and aligned to confirm that the positioning component 3 in the mounting groove 12 and moving ring groove 13 on the outer wall of the plug end 1 is in the initial storage state. The guide plate component 32 is stored in the mounting groove 12 and is limited and fixed by the positioning protrusion component 33 and the auxiliary spring block component 34. All components are in the pluggable working state.

[0055] S2. The moving ring 31 in the moving annular groove 13 is pushed upward axially. The moving ring 31 drives the push plate 322 to move through the mounting ear 35 and the shaft 36. The push plate 322 pulls the guide plate 321 to rotate and open around the fixed shaft 325 through the rotating shaft 327, so that the guide plate 321 and the outer wall of the plug end 1 form an acute angle. After the guide plate 321 is opened, the plug end 1 can be positioned inside the socket end 2 through the guide plate 321, so as to achieve precise docking and positioning of the plug end 1 and the socket end 2.

[0056] S3. After positioning is completed, reset and push the moving ring 31 to reset the guide plate 321 and push plate 322 into the mounting groove 12. Then rotate the plug end 1 and use the threaded structure of the outer wall of the moving ring 31 to lock it with the threaded engagement of the inner wall of the socket end 2, thus restricting the axial and circumferential loosening of the plug end 1 and the socket end 2.

[0057] S4. If unlocking is required, rotate the plug end 1 in the opposite direction to release the threaded lock of the moving ring 31. Pull the moving ring 31 axially downward to drive the push plate 322 and the guide plate 321 to fold back and reset. The guide plate 321 presses the positioning protrusion 332 to compress the spring 333 and retracts out of the hole. At the same time, it presses down the auxiliary spring block 342 to compress the auxiliary lifting spring 343 and retracts. The guide plate assembly 32 is completely stored in the mounting groove 12. After the positioning constraint is released, the plug end 1 and the socket end 2 can be separated axially.

[0058] In this invention, the RF connector interface positioning structure includes a plug end 1 and a socket end 2 that are matched and plugged into each other. The plug end 1 has an inner conductor 11 inside, and the socket end 2 has a corresponding socket 21 that matches the inner conductor 11. Through the precise plugging and mating of the inner conductor 11 and the socket 21, stable conduction and transmission of RF signals are achieved.

[0059] Specifically, the outer wall of the plug end 1 is provided with a plurality of spaced mounting grooves 12 evenly spaced around its circumference. A movable annular groove 13 is provided circumferentially on the outer wall of the plug end 1 at the bottom of the plurality of mounting grooves 12. The mounting grooves 12 and the movable annular groove 13 are interconnected. Several sets of positioning components 3 are assembled inside the plurality of mounting grooves 12 and the movable annular groove 13. These positioning components 3 are evenly arranged in a ring to assist in the precise alignment and guiding positioning of the plug end 1 and the socket end 2 during insertion, effectively improving the problems of misalignment and inaccurate positioning in traditional RF connectors.

[0060] Specifically, the positioning component 3 includes a movable ring 31 slidably installed inside the movable ring groove 13, which can reciprocate vertically along the movable ring groove 13. Multiple sets of guide plate assemblies 32 are mounted on the upper end of the movable ring 31 at positions corresponding to multiple mounting slots 12. The up-and-down movement of the movable ring 31 synchronously drives the multiple sets of guide plate assemblies 32 to complete folding and unfolding actions within the mounting slots 12. A positioning protrusion assembly 33 and an auxiliary spring block assembly 34 are also mounted on the inner side of the upper end of the mounting slot 12. The positioning protrusion assembly 33 and the auxiliary spring block assembly 34 cooperate to limit and fix the guide plate assembly 32 in its retracted state, ensuring the stability of the overall structure when the connector is not inserted.

[0061] Specifically, the guide plate assembly 32 includes a guide plate 321 and a push plate 322. The guide plate 321 is located at the top opening of the mounting groove 12. The push plate 322 is connected to the tail of the guide plate 321, and the lower end of the push plate 322 is fixedly connected to the top of the moving ring 31. Multiple sets of push plates 322 can synchronously push and pull the corresponding guide plates 321 to complete the opening and closing action. A rotating sleeve 323 is provided at the top of the guide plate 321, and rotating ears 324 are symmetrically provided on both sides of the bottom end. A fixed shaft 325 adapted to the rotating sleeve 323 is fixedly installed at the top opening of the mounting groove 12. The guide plate 321 can achieve flipping and swinging through the cooperation of the rotating sleeve 323 and the fixed shaft 325. A docking sleeve 326 is provided at the top of the push plate 322 corresponding to the rotating ear 324. The docking sleeve 326 and the rotating ear 324 are both equipped with a rotating shaft 327, realizing the hinged linkage between the push plate 322 and the guide plate 321.

[0062] Specifically, the bottom end of the push plate 322 has a through hole 328, and the top end of the moving ring 31 is fixedly provided with a mounting ear 35. The mounting ear 35 and the through hole 328 are fitted together with a shaft 36, so that the bottom of the push plate 322 and the moving ring 31 are hinged together. When the moving ring 31 moves vertically up and down, the guide plate 321 can be driven to complete the folding and unfolding actions around the fixed shaft 325 by changing the angle of the push plate 322. The overall movement has strong linkage and high synchronization.

[0063] Specifically, the guide plate 321 has positioning holes 329, which are matched with the positioning protrusion assembly 33 for precise positioning in the retracted state. The length of the push plate 322 is limited to ensure that after the push plate 322 pushes the guide plate 321 open, the guide plate 321 and the outer wall of the plug end 1 form an acute angle structure, thus forming an outward-expanding guide structure for easy insertion. Both ends of the rotating shaft 327 and the shaft body 36 are equipped with limit structures to prevent the shaft from dislodging or shifting, ensuring the stability of the hinge structure. The upper end of the push plate 322 is set with a beveled structure on both sides of the docking sleeve 326 to effectively avoid motion interference and reduce the frictional resistance of the flipping mechanism.

[0064] Specifically, a push-pull groove 14 is provided on the inner side of the lower end of the mounting groove 12. The connection position between the push-pull groove 14 and the inner side of the upper end of the mounting groove 12 is set as a slope transition structure, which further provides clearance space for the swing displacement of the push plate 322 and ensures smooth movement of the rod. The positioning protrusion assembly 33 and the auxiliary spring block assembly 34 are both installed on the inner side of the upper end of the mounting groove 12, and the auxiliary spring block assembly 34 is located below the positioning protrusion assembly 33, which limits and constrains the guide plate 321 from both the outside and the inside.

[0065] Specifically, the positioning protrusion assembly 33 includes a telescopic groove 331 formed inside the mounting groove 12. A positioning protrusion 332 is movably installed inside the telescopic groove 331. A spring 333 is installed between the inner end of the positioning protrusion 332 and the bottom of the telescopic groove 331. The telescopic elasticity of the spring 333 enables the reciprocating telescopic movement of the positioning protrusion 332. A limit ring 334 is provided at the end edge of the positioning protrusion 332. A limit ring 335 adapted to the limit ring 334 is fixedly provided at the opening of the telescopic groove 331. The maximum extension amount is limited by the cooperation of the limit ring 334 and the limit ring 335 to prevent the positioning protrusion 332 from falling off. At the same time, the end of the positioning protrusion 332 is designed with a tapered structure to facilitate automatic squeezing and retraction, and alignment and locking when the guide plate 321 is reset and unfolded.

[0066] Specifically, the auxiliary spring block assembly 34 includes an auxiliary lifting groove 341 formed inside the mounting groove 12. The auxiliary lifting groove 341 is located below the positioning protrusion assembly 33. An auxiliary spring block 342 is installed inside the auxiliary lifting groove 341, and an auxiliary lifting spring 343 is fitted between the end of the auxiliary spring block 342 and the bottom of the auxiliary lifting groove 341. A limiting plate 344 is provided at the edge of the end of the auxiliary spring block 342, and a limiting strip 345 adapted to the limiting plate 344 is provided at the opening of the auxiliary lifting groove 341 to limit the ejection stroke of the auxiliary spring block 342 and prevent it from falling out. The end of the auxiliary spring block 342 is always pressed against the inside of the guide plate assembly 32, providing continuous support and limiting for the guide plate 321 in the retracted state.

[0067] Specifically, the outer wall of the moving ring 31 is provided with a threaded structure, which can be adapted and screwed into the threaded structure on the inner wall of the socket end 2 to achieve threaded locking and fixation of the plug end 1 and the socket end 2. After all positioning components 3 are assembled, the overall structure does not exceed the outer wall groove of the mounting groove 12, has no exposed protrusions, and does not change the original external dimensions of the connector. The outer walls of both the plug end 1 and the socket end 2 are provided with anti-slip sections 4 and rotating sections 5, which facilitate the operator's grip and application of force, improving the convenience of assembly and disassembly.

[0068] This device adopts a ring-shaped, evenly distributed, expandable guide plate structure. Before insertion, multiple sets of guide plates are synchronously stretched to form an acute-angle guide surface, which can automatically correct radial offset and angular deviation during the insertion process of the plug end, ensuring high-precision coaxial connection between the inner conductor and the socket. This effectively avoids problems such as insertion scratches, top pressure deformation, and poor contact, significantly reducing the risk of RF signal loss and standing wave degradation, and ensuring long-term stable electrical transmission performance of the connector.

[0069] The entire positioning assembly can be stored inside the mounting slot when not plugged in. The structure does not extend beyond the outer wall of the plug end, has no extra protrusions, does not change the overall shape and installation size of the connector, does not require modification of the equipment mounting cavity, can be directly adapted to existing standard installation spaces, will not interfere with surrounding components, and is suitable for use in various communication and industrial control RF equipment.

[0070] The system employs a linkage structure that uses a single moving ring to drive multiple guide plate assemblies. All guide plates open and close synchronously, ensuring uniform force distribution along the circumference and eliminating localized guide deviation. Combined with a multi-axis hinged folding structure and a sloped avoidance design, the rods swing smoothly without jamming. Furthermore, limiting structures are installed at both ends of each rotating shaft to effectively prevent loosening and misalignment, thereby improving the stability and service life of the reciprocating motion of the structure.

[0071] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
