Description

Technical Field

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

[0002] Radio frequency (RF) connectors are core components used for transmitting RF signals and are widely used in coaxial cables, antenna systems, communication equipment, test instruments, and aerospace. With the rapid development of wireless communication technology, communication equipment is constantly evolving towards miniaturization, higher frequencies, and higher reliability, placing increasingly higher demands on the performance of RF connectors.

[0003] In the mating process of RF connectors, the pins are the key components responsible for signal transmission. The mating accuracy between the pins and the socket directly determines the electrical performance and mechanical reliability of the connector. However, in actual mating operations, due to limited operating space, blind spots, and cumulative errors after multiple mating and unmating operations, it is often difficult to achieve precise alignment between the pins of the male connector and the socket of the female connector. When there is axial or angular deviation between the pins and the socket, the pins are prone to skewing, bending, or even breaking, which not only leads to unstable signal transmission but may also cause permanent damage to the entire connector.

[0004] Furthermore, existing RF connector guidance methods mostly rely on positioning stops on the connector shell end face for coarse guidance, which can only align the overall connector shell and cannot directly and precisely guide the slender internal pins. Especially in multi-channel RF connectors and blind-mating RF connector applications, the assembly space is limited, and the alignment of the internal pins cannot be observed with the naked eye. The shell being properly guided does not mean that the internal pins are coaxial with the socket, and the pins are still prone to eccentric impact. Most existing guidance structures are integrated into the female socket component, and structural modifications are concentrated on the female end. The male pins themselves have no auxiliary guidance structure, resulting in poor versatility and incompatibility with existing standard RF pin specifications. Modification requires replacing the entire female component, leading to high material costs.

[0005] Therefore, it is necessary to invent a RF connector pin guiding structure and its usage method to solve the above problems. Summary of the Invention

[0006] (a) Purpose of the invention

[0007] The purpose of this invention is to provide a RF connector pin guide structure and its usage method.

[0008] (II) Technical Solution

[0009] To achieve the above objectives, the present invention provides the following technical solution: a radio frequency connector pin guide structure, including a female and a male connector adapted to the radio frequency connector, wherein a coarse guide component is installed on the outside of the female connector and a socket sleeve is provided inside the female connector, and a pin adapted to the socket sleeve is provided inside the male connector, wherein a fine guide component is installed on the outside of the pin.

[0010] The coarse guide assembly includes multiple positioning and moving slots disposed outside the female head, a coarse guide sleeve installed outside the multiple positioning and moving slots, and multiple positioning and moving blocks adapted to the positioning and moving slots on the inner wall of the coarse guide sleeve.

[0011] The precision guiding assembly includes multiple movable mounting slots disposed on the outer wall of the pin, with movable blocks installed in the multiple movable mounting slots. A guide plate is connected to the end of each movable block, and a guide connecting strip is provided between adjacent guide plates. A pushing component is provided on one side of each movable block, and the pushing component lifts the guide plate. The guide plate rotates on one side of the movable block, and the multiple guide plates and the guide connecting strip together form a guiding area. The guiding area is adapted to the socket sleeve and guides the pin to be inserted into the socket sleeve.

[0012] Preferably, the movable mounting groove is provided with at least three sets, and rolling grooves are provided on both sides of its inner wall. Rollers are installed in the rolling grooves on both sides, and a shaft is installed between the rollers on both sides. The shaft is set in the rotating hole inside the movable block. Fixed ears are provided on both sides of the top of the movable block. A fixed plate is provided at the end of the guide plate. Rotating shafts matching the fixed ears are provided on both sides of the end of the fixed plate. The rotating shafts rotate in the fixed ears, and each end of the rotating shaft is provided with a limiting ring.

[0013] Preferably, the pushing component includes a telescopic groove disposed on one side of the moving block, a pushing protrusion installed in the telescopic groove, a spring provided between the end of the pushing protrusion and the bottom of the telescopic groove, a limiting ring provided at the opening of the telescopic groove, a limiting plate adapted to the limiting ring provided at the edge of the end of the pushing protrusion, and the pushing protrusion abutting against the end of the guide plate and causing it to rotate on one side of the moving block.

[0014] Preferably, a lifting spring is installed between the bottom of the movable block and the bottom of the movable mounting groove, and multiple lifting springs together lift multiple movable blocks.

[0015] Preferably, the male connector has a positioning groove on the outer side of the bottom of the pin to accommodate the guide plate, and a recessed groove adapted to the guide connecting strip is provided between adjacent positioning grooves. The guide connecting strip is made of elastic material.

[0016] Preferably, the top of the pin is hemispherical, and when the fine guide assembly moves to the upper end of the pin, the multiple guide plates extend beyond the outside of the male connector end.

[0017] Preferably, the coarse guide sleeve is bucket-shaped and is positioned towards the female head docking end. The coarse guide sleeve is fitted onto the outer wall of the female head, and the positioning moving groove and the positioning moving block are matched in shape, both being arc-shaped.

[0018] Preferably, the inner wall of the female connector end is curved, the top of the male connector end is also curved, and the inner wall of the socket sleeve end is provided with a guide surface.

[0019] Preferably, the outer wall of the male head and the inner wall of the female head are provided with matching thread structures.

[0020] A method of using a radio frequency connector pin guide structure includes:

[0021] S1. Perform preliminary docking of the male and female connectors. Utilize the flared structure of the outer bucket-shaped coarse guide sleeve of the female connector, along with the sliding fit of the arc-shaped positioning moving groove and the positioning moving block, to achieve preliminary coarse positioning and correction of the docking position of the male and female connectors, and complete the preliminary alignment of the connector.

[0022] S2. After the coarse guide alignment is completed, the guide plate is continuously lifted by the push component, so that the guide plate rotates and unfolds with the moving block as the reference. With the adaptive movement of the moving block in the moving installation slot, the enclosed guide area is precisely aligned with the socket sleeve inside the female head. Using the limiting and guiding effect of the guide area, the pin inside the male head is precisely guided to be inserted into the socket sleeve axis position.

[0023] S3. Under the precise guidance of the precision guide component, the male and female connectors are pushed to fit together and connect, so that the pins are smoothly inserted into the socket sleeve. After the connection is completed, the connection position of the male and female connectors is locked, and the precise assembly and connection of the RF connector is completed.

[0024] Compared with the prior art, the beneficial effects of the above-mentioned technical solution of the present invention are:

[0025] 1. This invention provides a wide range of physical guidance in the initial stage of male and female head docking by setting a bucket-shaped coarse guide sleeve on the outside of the female head and cooperating with the positioning moving groove and positioning moving block. This effectively compensates for the axial offset and can smoothly guide the pin into the range of the female head port even if there is a large initial installation angle deviation.

[0026] 2. The present invention provides a guide area outside the pin, which is formed by a guide plate and a guide connecting strip. This area is close to the pin and extends to the outside of the male end face. It performs a second precision alignment before the pin enters the socket sleeve to ensure that the end of the pin is accurately aligned with the guide surface of the socket sleeve, thereby fundamentally preventing the pin from bending or being damaged due to oblique insertion or top contact.

[0027] 3. The male connector of the present invention has a positioning groove for accommodating the guide plate and a recessed groove for adapting the guide connecting strip. When the pin is fully inserted into the socket sleeve, the fine guide assembly is compressed back into the male connector and neatly stored in the groove. The final locking of the male and female connectors will not be affected by the guide structure occupying extra axial space, thus ensuring reliable contact of the connection interface and stable radio frequency transmission characteristics.

[0045] In this invention, a lifting spring 47 is installed between the bottom of the movable block 42 and the bottom of the movable mounting groove 41, and multiple lifting springs 47 together lift multiple movable blocks 42.

[0046] In this invention, the bottom outer side of the male head 2 internal pin 21 is provided with a positioning groove 22 for accommodating the guide plate 43, and a recessed groove 23 for adapting the guide connecting strip 44 is provided between adjacent positioning grooves 22. The guide connecting strip 44 is made of elastic material.

[0047] In this invention, the top of the pin 21 is hemispherical. When the fine guide assembly 4 moves to the upper end of the pin 21, multiple guide plates 43 extend beyond the outside of the male head 2 mating end.

[0048] In this invention, the coarse guide sleeve 32 is generally bucket-shaped and is positioned towards the docking end of the female head 1. The coarse guide sleeve 32 is generally fitted onto the outer wall of the female head 1, and the positioning moving groove 31 and the positioning moving block 33 are matched in shape and are both arc-shaped.

[0049] In this invention, the inner wall of the female connector 1 is arc-shaped, the top of the male connector 2 is also arc-shaped, and the inner wall of the end of the insertion sleeve 11 is provided with a guide surface 12.

[0050] In this invention, the outer wall of the male head 2 and the inner wall of the female head 1 are provided with matching thread structures.

[0051] In this invention, the coarse guide component 3 includes multiple sets of positioning and moving grooves 31 opened on the outside of the female head 1. The positioning and moving grooves 31 are fitted with a coarse guide sleeve 32. The inner wall of the coarse guide sleeve 32 is integrally formed with multiple positioning and moving blocks 33 that are adapted to the positioning and moving grooves 31. The positioning and moving grooves 31 and the positioning and moving blocks 33 are all arc-shaped. The coarse guide sleeve 32 is generally bucket-shaped and is arranged facing the docking end of the female head 1. The coarse guide sleeve 32 is slidably fitted on the outer wall of the female head 1. The positioning and moving blocks 33 slide around the arc-shaped positioning and moving grooves 31 at a small angle in the circumference, allowing the coarse guide sleeve to have a slight position compensation.

[0052] In this invention, the precision guide component 4 includes at least three sets of movable mounting grooves 41 formed on the outer wall of the insert pin 21; rolling grooves 411 are formed on both sides of the inner wall of the movable mounting groove 41, and rollers 412 are assembled inside the rolling grooves 411 on both sides, and a shaft 413 is erected between the rollers 412 on both sides; the shaft 413 passes through the rotating hole 421 inside the movable block 42, and the movable block 42 can slide axially up and down along the movable mounting groove 41 by means of the cooperation of the rollers 412 and the shaft 413.

The rotating shafts 432 are rotatably assembled in the fixing ears 422, and the end of the rotating shafts 432 is equipped with a limiting ring 433. The limiting ring 433 restricts the axial movement of the guide plate 43, ensuring that the guide plate 43 can only rotate around the rotating shaft 432.

[0054] In this invention, an elastic guide connecting strip 44 is connected between adjacent guide plates 43; a pushing component 45 is provided on one side of the moving block 42; the pushing component 45 includes a telescopic groove 451 opened on the side of the moving block 42, a pushing protrusion 452 is installed inside the telescopic groove 451, and a spring 453 is assembled between the tail of the pushing protrusion 452 and the bottom of the telescopic groove 451; a limiting ring 454 is provided at the opening of the telescopic groove 451, and a limiting plate 455 is provided on the outer edge of the pushing protrusion 452. The limiting plate 455 and the limiting ring 454 cooperate with each other to prevent the pushing protrusion 452 from being completely pushed out and falling off by the spring 453. The head of the pusher 452 abuts against the side of the guide plate 43, and the guide plate 43 is pushed outward by the elastic force of the spring 453. The guide plate 43 opens outward around the rotation axis 432. Multiple guide plates 43, together with the guide connecting strip 44, form a cylindrical guide area 46. The inner diameter of the guide area 46 is adapted to the outer diameter of the socket sleeve 11, and is used to guide the pin 21 to align with the socket sleeve 11.

[0055] In this invention, a lifting spring 47 is installed between the bottom surface of the movable block 42 and the bottom of the movable mounting groove 41, and multiple sets of lifting springs 47 simultaneously push each movable block 42 upward.

[0056] In this invention, a positioning groove 22 is formed on the outer side of the bottom of the pin 21 inside the male connector 2. The positioning groove 22 is used to receive the guide plate 43 after rotation and retraction. A recessed groove 23 is formed between adjacent positioning grooves 22. The recessed groove 23 is used to receive the guide connecting strip 44. The guide connecting strip 44 is made of high-resilience elastic rubber material and can deform as the guide plate 43 opens and closes.

[0057] In this invention, the top of the pin 21 is machined into a hemispherical shape; when the lifting spring 47 is in a free extension state, the fine guide assembly 4 is pushed to the upper position of the pin 21, the guide plate 43 opens outward, and the top of the guide plate 43 extends beyond the outside of the male head 2 mating end face.

[0058] In this invention, the inner wall of the female head 1 is machined into an introductory arc surface, and the inner wall of the end of the insertion sleeve 11 is machined into a guide surface 12; the top of the male head 2 is also provided with a chamfered arc surface; the outer wall of the male head 2 and the inner wall of the female head 1 are machined with interlocking thread structures, and after docking, they are locked and fixed by thread engagement.

[0059] A method of using a radio frequency connector pin guide structure includes:

[0060] S1. Initially align the male connector 2 with the female connector 1. Utilize the flared structure of the outer bucket-shaped coarse guide sleeve 32 of the female connector 1, along with the sliding fit of the arc-shaped positioning moving groove 31 and the positioning moving block 33, to achieve initial coarse positioning correction of the docking position of the male connector 2 and the female connector 1, and complete the initial alignment of the connector.

[0061] S2. After the coarse guide alignment is completed, the guide plate 43 is continuously lifted by the push component 45, so that the guide plate 43 rotates and unfolds with the moving block 42 as the reference. With the adaptive movement of the moving block 42 in the moving installation groove 41, the enclosed guide area 46 is precisely aligned with the insertion sleeve 11 inside the female head 1. Using the limiting and guiding effect of the guide area 46, the pin 21 inside the male head 2 is precisely guided to be inserted into the axial position of the insertion sleeve 11.

[0062] S3. Under the precise guidance of the precision guide component 4, the male connector 2 and the female connector 1 are pushed to fit together and connect, so that the pin 21 is smoothly inserted into the socket sleeve 11. After the connection is completed, the connection position of the male connector 2 and the female connector 1 is locked, and the precise assembly and connection of the RF connector is completed.

[0063] In this invention, the coarse guide component first completes the initial alignment with large deviations, and the bucket-shaped coarse guide sleeve, together with the arc-shaped groove-block, can float to compensate for assembly errors and misalignment of the mounting base; then the fine guide component achieves micron-level centering guidance, avoiding direct impact of the pins on the socket sleeve opening, greatly reducing the risk of pin bending, chipping, and socket sleeve scratch failure, and improving the lifespan of the RF connector after repeated insertion and removal.

[0064] In this invention, after being pressed, the entire precision guide assembly can be axially retracted into the male head. The guide plate and guide connecting strip are respectively housed in the positioning groove and the recessed groove, which will not occupy the mating space between the pin and the socket sleeve, will not affect the thread locking of the male and female heads, and will not interfere with the contact performance of the radio frequency signal. After disassembly, the spring drive automatically resets and opens, without the need for manual reset.

[0065] In this invention, the moving block relies on rollers and shafts to roll and slide along the moving mounting groove, resulting in low frictional resistance and avoiding jamming; the guide plate adopts a rotating shaft hinge structure, and the limiting ring restricts axial detachment; the pushing component adopts a limiting ring and limiting plate structure, so the pushing protrusion will not pop out and fall off, the structure is stable, and it is suitable for use in RF connectors under vibration conditions.

[0066] 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.
