Technical Field

[0001] This invention relates to the field of radio frequency connector technology, and in particular to radio frequency floating socket components, radio frequency pin components, and integrated connectors.

[0002] Background technology.

[0003] With the increasing demand for miniaturization, integration, and high reliability in electronic devices, the requirements for high-frequency, high-density integrated radio frequency (RF) contacts are also becoming more stringent. Currently, miniaturized RF contacts suffer from poor guidance and low reliability in preventing misalignment. For example, the floating signal contact and electrical connector using the contact disclosed in the invention patent with authorization announcement date of July 18, 2012 (CN101662115B), the RF connector disclosed in the utility model patent with authorization announcement date of October 4, 2022 (CN217545029U), and the floating structure RF contact and connector disclosed in the invention patent with authorization announcement date of March 19, 2024 (CN113871919B) all suffer from issues where the guiding structure is easily damaged during pin-hole mating, and the housing guidance is unreasonable.

[0004] Therefore, for miniaturized RF contacts, there is an urgent need to improve their guiding properties and anti-misalignment performance.

[0005] It should be noted that the above technical information is intended only to enhance the understanding of the overall background technology of the present invention, and should not be regarded as an admission or in any way implying that the above technical information constitutes prior art known to those skilled in the art. Summary of the Invention

[0006] To address the shortcomings in the aforementioned background technology, this invention proposes an RF floating socket component, an RF pin component, and an integrated connector. The technical problem to be solved is: how to improve the reliability of RF contact mating and avoid damage to the guiding structure.

[0007] The technical solution of this invention is as follows: A radio frequency (RF) floating jack component includes an outer jack conductor and a center jack conductor. The center jack conductor is disposed inside the outer jack conductor through a jack insulator. The end of the center jack conductor is used to insert a pin center conductor of an RF pin assembly. The outer jack conductor includes a housing 1 and a housing 2, which together serve as the insertion part of the RF pin assembly, and a housing 3, which is slidably sleeved outside the housing 2 and used to connect to a socket housing. An elastic element is provided between the housing 2 and the housing 3. The housing 1 is sleeved at the end of the housing 2. The end of the housing 1 is provided with a tapered primary guide structure for guiding and calibrating the RF pin assembly. The end of the housing 2 located inside the housing 1 is provided with a tapered secondary guide structure for guiding and calibrating the RF pin assembly.

[0008] Based on the above technical solutions, as a preferred technical solution for the radio frequency floating socket component, the conical primary guide structure includes a flange extending radially inward along the housing. The inner ring wall of the flange is funnel-shaped and includes a conical surface at the outer end and a cylindrical surface at the inner end. The diameter of the cylindrical surface is smaller than the maximum diameter of the inner hole of the conical secondary guide structure and larger than the minimum diameter of the inner hole of the conical secondary guide structure.

[0009] Based on the above technical solutions, as a preferred technical solution for the radio frequency floating socket component, the conical secondary guide structure is a plurality of spring pieces formed by the bifurcation of the housing. The cavity formed by each spring piece is funnel-shaped and includes a conical surface at the outer end, a cylindrical surface at the inner end, and a smooth transition surface connecting the conical surface and the cylindrical surface. The minimum diameter of the inner hole of the conical primary guide structure is greater than the diameter of the cylindrical surface and less than the maximum diameter of the conical surface.

[0010] Based on the above technical solution, as a preferred technical solution for the radio frequency floating socket component, the outer conductor of the socket also includes a fourth housing connected to the second housing, a third housing sleeved outside the fourth housing, the first housing, the second housing, the third housing, and the fourth housing are arranged coaxially, the third housing and the fourth housing are slidably fitted together and a limiting step is provided between them to limit the sliding stroke.

[0011] Based on the above technical solution, as a preferred technical solution for the radio frequency floating socket component, two socket insulators are provided, both of which are injection molded and embedded as one piece with the socket center conductor. The two socket insulators are respectively connected to housing two and housing four. Housing two is provided with a positioning step for limiting the socket insulators. The tail of the socket center conductor is connected with an insulating spacer one for separating the conductor core and the conductor shielding layer.

[0012] Based on the above technical solutions, as a preferred technical solution for the radio frequency floating socket component, at the forced mounting position of the housing one and the housing two, a riveting area is provided on the housing one, and the deformation structure generated on the inner wall after the housing one is riveted matches the groove opened on the outer periphery of the housing two.

[0013] A radio frequency (RF) pin component includes an outer pin conductor and a center pin conductor. The center pin conductor is disposed inside the outer pin conductor through a pin insulator. During the insertion process with the RF floating socket component described in any of the above technical solutions, the insertion end of the outer pin conductor is guided and corrected in sequence by a tapered primary guide structure and a tapered secondary guide structure, and then the center pin conductor is inserted and adapted to the socket center conductor.

[0014] Based on the above technical solutions, as a preferred technical solution for the radio frequency pin component, the pin insulator and the pin center conductor are an integral structure of injection molding and embedding. The pin outer conductor is provided with a positioning step for limiting the pin insulator, and the tail of the pin center conductor is connected with an insulating spacer for separating the wire core and the wire shielding layer.

[0015] Based on the above technical solutions, as a preferred technical solution for the RF pin component, the mating end of the pin's outer conductor is chamfered, and a tapered three-stage guiding structure is provided between the mating ends of the pin's central conductor and the socket's central conductor. Preferably, the mating portion of the pin's central conductor is provided with a mating slot, and the mating portion of the socket's central conductor is provided with a mating post adapted to the mating slot; or the opposite arrangement is made, with the mating portion of the pin's central conductor provided with a mating post, and the mating portion of the socket's central conductor provided with a mating slot adapted to the mating slot.

[0016] An integrated connector includes a socket housing and a plug housing. The socket housing is connected to a plurality of radio frequency floating socket components as described in any of the above technical solutions via positioning claw one. The plug housing is connected to radio frequency pin components as described in any of the above technical solutions via positioning claw two. The number of radio frequency pin components is the same as the number of radio frequency floating socket components.

[0017] Based on the above technical solution, as a preferred technical solution of the integrated connector, the socket housing is provided with a socket component mounting hole connected to a socket component positioner. The socket component positioner includes a cylindrical structure segment one that slides with the radio frequency floating socket component, a cylindrical structure segment two that is interference-fitted with the tail of the socket component mounting hole, and a conical sheath one. The inner diameters of the cylindrical structure segment one, the cylindrical structure segment two, and the conical sheath one decrease sequentially.

[0018] Based on the above technical solution, as a preferred technical solution of the integrated connector, the pin component mounting hole provided on the plug housing is connected to a pin component positioner. The pin component positioner includes a cylindrical section one nested with the radio frequency pin component, a cylindrical section two that is interference-fitted with the tail of the pin component mounting hole, and a conical sheath two. The inner diameters of the cylindrical section one, the cylindrical section two, and the conical sheath two decrease sequentially.

[0019] Compared with existing technologies, this invention not only provides a novel RF floating jack component, but also a novel RF pin component, and a novel integrated connector. The core of this invention lies in the following: the RF floating jack component employs a single-unit housing 1 and housing 2. Housing 1 is fitted onto the end of housing 2. The end of housing 1 is provided with a tapered primary guide structure for guiding and calibrating the RF pin component. The end of housing 2, located within housing 1, is provided with a tapered secondary guide structure for guiding and calibrating the RF pin component. During the mating process between the RF pin component and the RF floating jack component, the mating end of the pin's outer conductor is guided and calibrated sequentially by the tapered primary guide structure and the tapered secondary guide structure. Then, the pin's central conductor is mated with the central conductor of the jack, forming a multi-stage guiding, calibrating, and mating structure. This allows for precise mating without damaging the guide structure. Preferably, the tapered primary guide structure uses an open six-lobed slot (i.e., several spring contacts) at the mating portion of housing 2. Because the tapered primary guide structure is built into housing 1, it is effectively protected in both radial and axial directions. For the integrated connector provided by this invention, the two-level guidance between the outer conductors of the RF pin component and the RF floating socket component, the insertion guidance between the center conductors of the RF pin component and the RF floating socket component, and the application of the socket component positioner and the pin component positioner, can effectively improve the smoothness of mating when using the multi-core bundled RF connector. Furthermore, in some technical solutions of this invention, the inlay process structure between the socket outer conductor, the socket center conductor, and the socket insulator, the inlay process structure between the pin outer conductor, the pin center conductor, and the pin insulator, as well as the connection method and assembly structure between housing one, housing two, housing three, and housing four, all improve the efficiency of machining and assembly.

[0029] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, they should be considered part of the specification.

[0030] A radio frequency floating jack component, such as Figure 1 and Figure 2 As shown, it includes an outer conductor 1-1 and a center conductor 1-2. The center conductor 1-2 is disposed inside the outer conductor 1-1 through a socket insulator 1-3. The end of the center conductor 1-2 is used to insert the center conductor 2-2 of the adapter RF pin component 2. This part has the same functional characteristics as the prior art.

[0031] like Figure 13 and Figure 14As shown, the tail end of the outer conductor 1-1 of the socket is used to connect to the wire shielding layer of the shielded cable, while the other end of the outer conductor 1-1 of the socket is used to interlock with the outer conductor 2-1 of the RF pin component 1. Thus, the outer conductor 1-1 of the socket, the wire shielding layer, and the outer conductor 2-1 of the pin together constitute the shielding layer of the enveloping wire core, the central conductor 1-2 of the socket, and the central conductor 2-2 of the pin. One end of the central conductor 1-2 of the socket is used to connect to the wire core of the shielded cable, and the other end is used to interlock with the central conductor 2-2 of the pin of the RF pin component 2.

[0032] like Figure 3 As shown, the outer conductor 1-1 of the socket includes a housing 1-1-1 and a housing 1-1-2, which together serve as the insertion part of the RF pin component 2. Specifically, housing 1-1-1 and housing 1-1-2 together act as the insertion part and are fitted to the outer conductor 2-1 of the RF pin component 1. Specifically, housing 1-1-1 is coaxially sleeved on the end of housing 1-1-2, providing axial and radial protection to the end of housing 1-1-2. The end of housing 1-1-1 is provided with a tapered primary guide structure for guiding and calibrating the RF pin component 2, and the end of housing 1-1-2 located inside housing 1-1-1 is provided with a tapered secondary guide structure for guiding and calibrating the RF pin component 2. Thus, housing 1-1-1 can provide axial and radial protection to the tapered secondary guide structure.

[0033] like Figure 13 and Figure 14 As shown, during the mating process between the RF pin component 2 and the RF floating socket component 1, firstly, the conical primary guiding structure of the RF floating socket component 1 contacts the outer conductor 2-1 of the pin of the RF pin component 2, enabling primary guidance and correction during the mating process; then, the conical secondary guiding structure of the RF floating socket component 1 contacts the outer conductor 2-1 of the pin of the RF pin component 2, enabling secondary guidance and correction during the mating process; as the mating process continues, the central conductor 1-2 of the socket of the RF floating socket component 1 finally mates with the central conductor 2-2 of the pin of the RF pin component 2.

[0034] The outer conductor 1-1 of the socket also includes a third housing 1-1-3 that is slidably sleeved outside the second housing 1-1-2 and used to connect to the socket housing 10. An elastic element 1-1-5, preferably a helical columnar spring, is provided between the second housing 1-1-2 and the third housing 1-1-3. During the insertion process between the RF pin component 2 and the RF floating socket component 1, since the first housing 1-1-1, the second housing 1-1-2, and the central conductor 1-2 of the socket are integrally connected, this integral connection structure can move relative to the third housing 1-1-3, that is, it can move relative to the socket housing 10, thereby providing a floating correction function during the insertion process between the RF pin component 2 and the RF floating socket component 1.

[0035] Based on the above technical solutions, the preferred technical solution for the radio frequency floating jack component is as follows: Figure 3 As shown, the conical primary guide structure includes a flange 1-1-11 extending radially inward along the housing 1-1-1. The outer wall of the housing 1-1-1 protects the conical secondary guide structure radially, preventing it from bending and becoming unrecoverable due to impact from the outer conductor 2-1 of the RF pin component 2; while the flange 1-1-11 protects the conical secondary guide structure axially, preventing it from bending or collapsing due to impact from the outer conductor 2-1 of the RF pin component 2.

[0036] Specifically, the inner ring wall of the flange 1-1-11 is funnel-shaped and includes a conical surface 1-1-12 at the outer end and a cylindrical surface 1-1-13 at the inner end. The diameter of the cylindrical surface 1-1-13 is equal to the minimum diameter of the conical surface 1-1-12. Simultaneously, the diameter of the cylindrical surface 1-1-13 is smaller than the maximum diameter of the inner hole of the conical secondary guide structure, and larger than the minimum diameter of the inner hole of the conical secondary guide structure. During the insertion process between the RF pin component 2 and the RF floating socket component 1, the conical surface 1-1-12 first contacts the outer conductor 2-1 of the RF pin component 2, thereby guiding the outer conductor 2-1 of the RF pin component 2 to insert into the cylindrical surface 1-1-13. The cylindrical surface 1-1-13 further guides the outer conductor 2-1 of the pin to move axially towards the conical secondary guide structure.

[0037] Based on the above technical solutions, the preferred technical solution for the radio frequency floating jack component is as follows: Figure 3 As shown, the conical secondary guide structure consists of several spring pieces 1-1-21 formed by the forking of the housing 1-1-2. Each spring piece 1-1-21 is clearance-fitted with the housing 1-1-1, and the spring pieces 1-1-21 can form effective contact with the outer conductor 2-1 of the pin. The cavity formed by each spring piece 1-1-21 is funnel-shaped and includes a conical surface 1-1-22 at the outer end, a cylindrical surface 1-2-23 at the inner end, and a smooth transition surface 1-2-24 connecting the conical surface 1-1-22 and the cylindrical surface 1-2-23. The conical secondary guide structure comprises a conical surface 1-1-22, a smooth transition surface 1-2-24, and a cylindrical surface 1-2-23 arranged sequentially. The diameter of the cylindrical surface 1-2-23 is equal to the minimum diameter of the smooth transition surface 1-2-24, and the maximum diameter of the smooth transition surface 1-2-24 is equal to the minimum diameter of the conical surface 1-1-22. Preferably, six spring pieces 1-1-21 are provided.

[0038] The minimum diameter of the inner hole of the conical primary guide structure is greater than the diameter of cylindrical surface 1-2-23 and less than the maximum diameter of conical surface 1-1-22. That is, the diameter of cylindrical surface 1-1-13 of the conical primary guide structure is greater than the diameter of cylindrical surface 1-2-23 and less than the maximum diameter of conical surface 1-1-22. Preferably, the diameter of cylindrical surface 1-1-13 is greater than the minimum diameter of the smooth transition surface 1-2-24 and less than the maximum diameter of the smooth transition surface 1-2-24. During the insertion process between the RF pin component 2 and the RF floating socket component 1, after the cylindrical surface 1-1-13 guides the outer conductor 2-1 of the pin to move axially towards the conical secondary guide structure, the outer conductor 2-1 of the pin first contacts the conical surface 1-1-22 or the smooth transition surface 1-2-24. The smooth transition surface 1-2-24 then guides and corrects the outer conductor 2-1 of the pin to continue moving axially. Then, the outer conductor 2-1 of the pin contacts the cylindrical surface 1-2-23. Subsequently, the outer conductor 2-1 of the pin is guided and corrected by the cylindrical surface 1-2-23 formed by the various spring pieces 1-1-21 until the center conductor 1-2 of the socket of the RF floating socket component 1 and the center conductor 2-2 of the pin of the RF pin component 2 make insertion contact.

[0039] Based on the above technical solutions, the preferred technical solution for the radio frequency floating jack component is as follows: Figure 2 As shown, the outer conductor 1-1 of the socket also includes a fourth housing 1-1-4 connected to the second housing 1-1-2. The third housing 1-1-3 is sleeved on the fourth housing 1-1-4. The first housing 1-1-1, the second housing 1-1-2, the third housing 1-1-3, and the fourth housing 1-1-4 are arranged coaxially. The third housing 1-1-3 and the fourth housing 1-1-4 are slidably fitted together, and a limiting step 1-1-31 is provided between them to limit the sliding stroke.

[0040] Preferably, the end of the housing 1-1-4 is sleeved on the outside of the housing 1-1-3. The limiting step 1-1-31 includes a step provided at the front end of the housing 1-1-3 that is in stop-fitting with the wall structure of the housing 1-1-4, and also includes a step provided at the middle of the housing 1-1-4 that is in stop-fitting with the rear end of the housing 1-1-3.

[0041] Based on the above technical solutions, the preferred technical solution for the radio frequency floating jack component is as follows: Figure 4 As shown, there are two socket insulators 1-3, both of which are injection molded and embedded into the socket center conductor 1-2. The two socket insulators 1-3 are respectively connected to the housing 2 1-1-2 and the housing 4 1-1-4.

[0042] Preferably, a groove is provided at the position where the socket insulator 1-3 is installed on the center conductor 1-2 of the socket, and the socket insulator 1-3 is injection molded in the groove to prevent the socket insulator 1-3 from moving axially relative to the center conductor 1-2 of the socket.

[0043] Furthermore, a positioning step for limiting the insertion hole insulator 1-3 is provided inside the housing 2 1-1-2. It should be noted that during assembly, the insertion hole center conductor 1-2 with the insertion hole insulator 1-3 is inserted from the housing 4 1-1-4. Therefore, the positioning step is located inside the housing 2 1-1-2 and is used to position the insertion hole center conductor 1-2 in its final assembly position.

[0044] Preferably, such as Figure 12 , Figure 13 and Figure 14 As shown, the tail of the central conductor 1-2 of the socket is connected to an insulating spacer 1-4 for separating the conductor core and the conductor shielding layer. The insulating spacer 1-4 is interference-fitted with the inner cavity of the outer conductor 1-1 of the socket, which can prevent the central conductor 1-2 of the socket from retracting.

[0045] Preferably, the inner diameter of the front half of the housing 1-1-4 near the housing 3 1-1-3 is equal to the inner diameter of the housing 3 1-1-3 and smaller than the inner diameter of the tail of the housing 1-1-4. The socket insulator 1-3 connected to the housing 1-1-4 is located in the inner cavity of the front half of the housing 1-1-4 near the housing 3 1-1-3, and the insulating spacer 1-4 is located in the inner cavity of the tail of the housing 1-1-4.

[0046] Preferably, the insulating spacer 1-4 has a symmetrical hollow structure with a central hole. In use, the conductor core passes through the central hole and enters the wiring groove at the tail of the central conductor 1-2 of the socket. The conductor core and the wiring groove are welded together and then installed into the outer conductor 1-1 of the socket. The conductor shielding layer is welded and fixed to the housing 1-1-4. The housing 1-1-4 is designed with a tin-through hole 1-1-41, which can serve as an observation hole.

[0047] Based on the above technical solution, as a preferred technical solution for the radio frequency floating socket component, at the forced mounting position of housing 1-1-1 and housing 1-1-2, a riveting area is provided on housing 1-1-1. The deformation structure generated on the inner wall of housing 1-1-1 after riveting is adapted to the groove 1-1-25 opened on the outer periphery of housing 1-1-2. It should be noted that the opening position of the groove 1-1-25 is offset from the axial direction of the spring piece 1-1-21, ensuring that the spring piece 1-1-21 can move freely within housing 1-1-2.

[0048] An RF pin component, such as Figures 7 to 14As shown, it includes an outer conductor 2-1 and a center conductor 2-2. The center conductor 2-2 is disposed inside the outer conductor 2-1 via a pin insulator 2-3. During the insertion process with the RF floating jack component 1 described in any of the above technical solutions, the insertion end of the outer conductor 2-1 is guided and corrected by a tapered primary guide structure and a tapered secondary guide structure in sequence, and then the center conductor 2-2 is inserted and adapted to the jack center conductor 1-2.

[0049] Based on the above technical solutions, as a preferred technical solution for the radio frequency pin component, the pin insulator 2-3 and the pin center conductor 2-2 are an integral structure of injection molding and embedding. The pin outer conductor 2-1 is provided with a positioning step for limiting the pin insulator 2-3, which is used to position the pin center conductor 2-2 relative to the pin outer conductor 2-1.

[0050] Preferably, a groove is provided at the position where the pin insulator 2-3 is installed on the center conductor 2-2 of the pin, and the pin insulator 2-3 is injection molded in the groove to prevent the pin insulator 2-3 from moving axially relative to the center conductor 2-2 of the pin.

[0051] Preferably, the tail of the center conductor 2-2 of the pin is connected to an insulating spacer 2-4 for separating the conductor core and the conductor shielding layer. The insulating spacer 2-4 is interference-fitted with the inner cavity of the outer conductor 2-1 of the pin, which can prevent the center conductor 2-2 of the pin from retracting.

[0052] Preferably, the inner diameter of the front half of the outer conductor 2-1 is smaller than the inner diameter of the tail. The insulator 2-3 and the matching positioning step are both disposed in the inner cavity of the front half of the outer conductor 2-1, and the insulating spacer 2-4 is disposed in the inner cavity of the tail of the outer conductor 2-1.

[0053] Preferably, such as Figure 12 , Figure 13 and Figure 14 As shown, the insulating spacer 2-4 is a symmetrical hollow structure with a central hole. In use, the conductor core passes through the central hole and enters the wiring groove at the tail of the pin center conductor 2-2. The conductor core and the wiring groove are welded together and then installed into the pin outer conductor 2-1.
