Description

Technical Field

[0001] This application relates to the field of radio frequency device technology, and in particular to a coaxial connector and its replacement components. Background Technology

[0002] Coaxial connectors are mechatronic products, typically mounted on cables or instruments as electrical connection or disconnection components for transmission lines. They effectively transmit electromagnetic signals and energy. In antenna production, situations often arise where intermodulation fails to meet requirements, necessitating adjustments. In practice, this is primarily resolved by adjusting the position of cables and components, as well as the solder joints.

[0003] In related technologies, when adjusting the position and solder joints of cables and components on-site, the cables and coaxial connectors are typically connected by soldering the inner and outer conductors using specific external instruments before intercompatibility testing. This process is lengthy and involves numerous steps, and product performance cannot be guaranteed. Of course, there are also solderless coaxial connectors available, which usually use a clamped shielding layer for fixation; however, unstable contact is prone to occur during use. Summary of the Invention

[0004] Therefore, it is necessary to provide a coaxial connector and its replacement components to address at least one of the technical problems in the prior art, which can improve assembly efficiency, reduce maintenance costs, and ensure product performance.

[0005] On one hand, this application provides a replaceable component for a coaxial connector, the replaceable component comprising:

[0006] The cable includes a first inner conductor and a first outer conductor, wherein the first outer conductor is sleeved outside the first inner conductor and is insulated from the first inner conductor;

[0007] A second inner conductor, wherein the second inner conductor is welded to the first inner conductor; and

[0008] An intermediate connecting sleeve is fitted over the first outer conductor and electrically connected to the first outer conductor. The intermediate connecting sleeve is also used to detachably fit and fix the inner sleeve to the connector body and electrically connect to the connector body.

[0009] In one embodiment, the second inner conductor is connected to the first inner conductor by ultrasonic welding.

[0010] In one embodiment, the second inner conductor includes a first conductor segment and a second conductor segment, the first conductor segment being connected to the second conductor segment, the first conductor segment having an axially extending mounting hole near its end of the first inner conductor, the first inner conductor being inserted into the mounting hole and welded to the first conductor segment; the axial cross-sectional dimension of the first conductor segment is smaller than the axial cross-sectional dimension of the second conductor segment.

[0011] In one embodiment, the first outer conductor is crimped to the intermediate connecting sleeve.

[0012] In one embodiment, the intermediate connecting sleeve includes a first connecting sleeve and a second connecting sleeve, the first connecting sleeve being connected to the second connecting sleeve, the first connecting sleeve being sleeved over the first outer conductor and connected to the first outer conductor, the second connecting sleeve being detachably inner sleeved and fixed to the connector body, and the outer diameter of the first connecting sleeve being smaller than the outer diameter of the second connecting sleeve.

[0013] In one embodiment, the replaceable component further includes a first sealing ring, which is mounted on the outer wall of the second connecting sleeve and also abuts against the inner wall of the connector body.

[0014] In one embodiment, the outer wall of the second connecting sleeve is provided with a first mounting groove, and the first sealing ring is installed in the first mounting groove.

[0015] On the other hand, this application also provides a coaxial connector, including the aforementioned replaceable component, and further including a connector body, wherein the second inner conductor passes through the connector body and is insulated from the connector body, and the intermediate connecting sleeve is detachably inner sleeved and fixed to the connector body and electrically connected to the connector body.

[0016] In one embodiment, the inner wall of the connector body is provided with a plurality of first locking parts arranged sequentially at intervals along its circumferential direction, and the intermediate connecting sleeve is provided with a plurality of second locking parts arranged sequentially at intervals along its circumferential direction, and each of the first locking parts and each of the second locking parts are detachably locked together.

[0017] In one embodiment, the first locking portion includes a protrusion disposed on the inner wall of the connector body, the protrusion protruding toward the center of the connector body;

[0018] The second locking part includes a guide groove and a locking groove. One end of the guide groove is connected to the locking groove, and the other end of the guide groove extends axially to the end face of the intermediate connecting sleeve facing away from the cable. The locking groove is arranged around the circumference of the intermediate connecting sleeve. Both the guide groove and the locking groove are slidably engaged with the protrusion.

[0019] In one embodiment, the locking groove has a positioning recess on the side wall away from the cable, the positioning recess being recessed in a direction away from the cable, and the positioning recess engaging with the protrusion.

[0020] In one embodiment, all the first locking portions are arranged at equal intervals along the circumferential direction of the connector body on the inner wall of the connector body; all the second locking portions are arranged at equal intervals along the circumferential direction of the intermediate connecting sleeve on the intermediate connecting sleeve.

[0022] In one embodiment, the insulating assembly includes a first insulating sleeve and a second insulating sleeve.

[0023] In one embodiment, the coaxial connector further includes a second sealing ring connected between the outer wall of the second insulating sleeve and the inner wall of the connector body.

[0024] The aforementioned coaxial connector and its replaceable components allow for direct replacement of the replaceable components during maintenance, while the connector body is preserved and reused, reducing resource waste. The welding connection between the second inner conductor and the first inner conductor, as well as the connection between the intermediate connecting sleeve and the first outer conductor, can all be assembled in the factory, allowing the cable, second inner conductor, and intermediate connecting sleeve to form a single, standardized replaceable component.

Furthermore, during on-site maintenance, the replaceable component can be simply replaced, saving valuable on-site service time, travel costs, and potential losses due to improper maintenance. Fixing the welding process at the factory greatly simplifies on-site operations. Attached Figure Description

[0034] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0035] As described in the background section, the existing technology has many time-consuming procedures for adjusting the position and welding points of cables and components on-site, and the product performance cannot be guaranteed. This is because the construction quality of on-site maintenance personnel varies. If the process conditions do not meet the requirements during welding, it is easy to cause incomplete welding. The high temperature during welding may also damage the cable structure itself, which in turn will have a certain impact on the electrical performance of the entire cable assembly.

[0036] For the above reasons, this application provides a coaxial connector and its replacement components, which decouples the irreversible soldering process from the repeatable connector body, thereby solving the pain points of conventional soldering in field maintenance and high-reliability applications, and achieving "factory-level soldering, field-level replacement". This transforms field maintenance from a "technical task" into a simple "replacement operation", greatly reducing the technical requirements for maintenance personnel; and fundamentally eliminates the problem of inconsistent field construction quality, ensuring consistent RF performance at the network end.

[0037] The following will combine Figures 1 to 8 This application provides a detailed description of a replacement component for a coaxial connector according to one embodiment.

[0038] Please see Figures 1 to 4 For example, a replaceable component includes a cable 10. The cable 10 includes a first inner conductor 11 and a first outer conductor 12. The first outer conductor 12 is sleeved around the first inner conductor 11 and insulated from it. Optionally, both the first inner conductor 11 and the first outer conductor 12 are, for example, metal components, and include, but are not limited to, copper, aluminum, iron, or metal alloys. The specific materials can be flexibly adjusted and configured according to actual needs, and are not limited here. Optionally, the cable 10 also includes an insulating medium 13. The insulating medium 13 is disposed between the first inner conductor 11 and the first outer conductor 12, enabling the first inner conductor 11 and the first outer conductor 12 to be mutually insulated. Furthermore, the cable 10 also includes an insulating sheath 14. The insulating sheath 14 is sleeved around the first outer conductor 12. The insulating sheath 14 serves as the outer sheath of the first outer conductor 12, protecting it.

[0039] For example, the alternative component also includes a second inner conductor 20. The second inner conductor 20 is welded to the first inner conductor 11. Signals from the first inner conductor 11 are transmitted to the second inner conductor 20, and then from the second inner conductor 20 to the antenna device.

[0040] For example, the replaceable component also includes an intermediate connecting sleeve 30. The intermediate connecting sleeve 30 is sleeved over the first outer conductor 12 and electrically connected to the first outer conductor 12. The intermediate connecting sleeve 30 is also used to detachably sleeve and fix the inner part to the connector body 50 and electrically connect to the connector body 50. The intermediate connecting sleeve 30, the first outer conductor 12 and the connector body 50 are all grounded, which serves as a shielding function, making the signal transmission stable and reliable.

[0041] The replaceable components of the aforementioned coaxial connector allow for direct replacement during maintenance, while the connector body 50 is retained and reused, reducing resource waste. The welding connection between the second inner conductor 20 and the first inner conductor 11, and the connection between the intermediate connecting sleeve 30 and the first outer conductor 12, can all be assembled in the factory, allowing the cable 10, the second inner conductor 20, and the intermediate connecting sleeve 30 to form a single, standardized replaceable component. Compared to related technologies where welding is performed on-site by construction personnel, the replaceable component provided in this embodiment ensures consistent welding quality and impedance performance. Furthermore, during on-site maintenance, the replaceable component can be simply replaced, saving significant on-site service time, travel costs, and potential losses due to improper maintenance. By standardizing the welding process at the factory, on-site operations are greatly simplified, reducing on-site maintenance time from hours to minutes, which is strategically significant for ensuring the availability of critical infrastructure.

[0042] For example, the second inner conductor 20 and the first inner conductor 11 are ultrasonically welded together using high-precision automated equipment under strict quality control in the factory. Of course, other high-quality welding methods can also be used between the second inner conductor 20 and the first inner conductor 11, and this is not a limitation here. Thus, compared to conventional on-site laser welding, this embodiment not only provides excellent and consistent weld quality and impedance performance, but also avoids the high temperatures during welding affecting the cable 10 structure, while also meeting environmental protection and carbon reduction requirements.

[0043] For example, the first outer conductor 12 is crimped to the intermediate connecting sleeve 30. Specifically, the crimping operation between the first outer conductor 12 and the intermediate connecting sleeve 30 is performed using high-precision automated equipment under strict quality control at the factory. This results in excellent and consistent quality and impedance performance, avoids the impact of high temperatures during welding heating on the cable 10 structure, and also meets environmental protection and carbon reduction requirements.

[0044] Of course, the first outer conductor 12 and the intermediate connecting sleeve 30 can also be connected by other methods such as welding, which are not specifically limited here.

[0045] Please see Figure 3 and Figure 4In some embodiments, the second inner conductor 20 includes a first conductor segment 21 and a second conductor segment 22. The first conductor segment 21 is connected to the second conductor segment 22, and the end of the first conductor segment 21 near the first inner conductor 11 has a mounting hole extending along the Z-axis. The first inner conductor 11 is inserted into the mounting hole and welded to the first conductor segment 21.

[0046] In this embodiment, the axial Z-section dimension of the first conductor segment 21 is smaller than that of the second conductor segment 22. Specifically, this embodiment takes the example where both the first conductor segment 21 and the second conductor segment 22 are cylinders, and the diameter of the first conductor segment 21 is smaller than the diameter of the second conductor segment 22. The ratio of the diameter of the first conductor segment 21 to the diameter of the first inner conductor 11 is, but is not limited to, 1.2 to 5, specifically, for example, 1.2, 1.5, 2, 3, 4, or 5. That is, the diameter of the first conductor segment 21 is slightly larger than the diameter of the first inner conductor 11, which satisfies the requirement for the first conductor segment 21 and the first inner conductor 11 to be connected and fixed to each other, and the space occupied by the first conductor segment 21 is small. The second conductor segment 22 serves as the main body of the second inner conductor 20. The diameter of the second conductor segment 22 is larger than the diameter of the first conductor segment 21, which ensures the overall structural strength of the second inner conductor 20, guarantees stability, and enables connection with external devices such as combiners. The second inner conductor 20 passes through the connector body 50 and is coaxially arranged with the connector body 50. Therefore, the diameter of the second inner conductor 20 is smaller than the inner diameter of the connector body 50.

[0047] In some embodiments, the intermediate connecting sleeve 30 includes a first connecting sleeve 31 and a second connecting sleeve 32. The first connecting sleeve 31 is connected to the second connecting sleeve 32. The first connecting sleeve 31 is sleeved over the first outer conductor 12 and connected to the first outer conductor 12. Specifically, the first connecting sleeve 31 and the first outer conductor 12 are connected by crimping. The second connecting sleeve 32 is detachably and innerly fixed to the connector body 50. Furthermore, the outer diameter of the first connecting sleeve 31 is smaller than the outer diameter of the second connecting sleeve 32. Since the outer diameter of the first outer conductor 12 is small, the inner and outer diameters of the first connecting sleeve 31 sleeved over the first outer conductor 12 can be designed to be correspondingly smaller. To achieve inner fixing of the second connecting sleeve 32 to the connector body 50, the outer diameter of the second connecting sleeve 32 is the same as the inner diameter of the connector body 50. The outer diameter of the second connecting sleeve 32 is larger, allowing the intermediate connecting sleeve 30 to be stably installed on the connector body 50.

[0048] For example, the replaceable component also includes a first sealing ring 40. The first sealing ring 40 includes, but is not limited to, an O-ring. The first sealing ring 40 is mounted on the outer wall of the second connecting sleeve 32 and also abuts against the inner wall of the connector body 50. When the second connecting sleeve 32 and the connector body 50 are assembled together, the first sealing ring 40 is in a compressed state. This improves the sealing performance between the second connecting sleeve 32 and the connector body 50, and increases the separation resistance between the first sealing ring 40 and the connector body 50, thereby enhancing the connection stability between the intermediate connecting sleeve 30 and the connector body 50 and effectively preventing loosening.

[0049] Based on the aforementioned embodiment, the outer wall of the second connecting sleeve 32 is provided with a first mounting groove 321. The first sealing ring 40 is installed in the first mounting groove 321.

[0050] Please see Figures 1 to 4 In another embodiment, this application also provides a coaxial connector including replaceable components of any of the above embodiments. The coaxial connector further includes a connector body 50, which is also the second outer conductor. The outer wall of the connector body 50 is provided with an interface thread 51. The interface thread 51 is, for example, SMA type, N type, etc., and the interface thread 51 can withstand multiple insertions and removals without damage or affecting performance, so the connector body 50 can be reused.

[0051] The second inner conductor 20 passes through the connector body 50 and is insulated from the connector body 50. The intermediate connecting sleeve 30 is detachably fixed to the connector body 50 and electrically connected to the connector body 50.

[0052] When maintenance is required, the aforementioned coaxial connector can be directly replaced with a replaceable component, allowing the connector body 50 to be retained and reused, reducing resource waste. The welding connection between the second inner conductor 20 and the first inner conductor 11, and the connection between the intermediate connecting sleeve 30 and the first outer conductor 12, can all be assembled in the factory, making the cable 10, the second inner conductor 20, and the intermediate connecting sleeve 30 a single, replaceable component—a standardized part. Compared to related technologies where welding is performed on-site by construction personnel, the replaceable component provided in this embodiment ensures consistent welding quality and impedance performance. Furthermore, during on-site maintenance, the replaceable component can be simply replaced, saving significant on-site service time, travel costs, and potential losses due to improper maintenance. By standardizing the welding process at the factory, on-site operations are greatly simplified, reducing on-site maintenance time from hours to minutes, which is strategically significant for ensuring the availability of critical infrastructure.

[0053] Please see Figure 3 , Figures 6 to 8 In some embodiments, the inner wall of the connector body 50 is provided with a plurality of first locking portions 52 arranged sequentially at intervals along its circumferential direction. The number of first locking portions 52 includes, but is not limited to, two, three, four, six, eight, or any other arbitrary number. The intermediate connecting sleeve 30 is provided with a plurality of second locking portions 33 arranged sequentially at intervals along its circumferential direction. The number of second locking portions 33 is the same as that of the first locking portions 52. There are many specific structural forms for the first locking portions 52 and the second locking portions 33, which are not limited here, as long as they can achieve stable locking between the first locking portions 52 and the second locking portions 33. Each first locking portion 52 and each second locking portion 33 are correspondingly and detachably locked together. Increasing the number of each of the first locking portions 52 and the second locking portions 33 can improve the stability of the connection between the intermediate connecting sleeve 30 and the connector body 50. In this embodiment, four second locking portions 33 are specifically provided as an example.

[0054] Based on the aforementioned embodiments, the first locking portion 52 includes a protrusion 521 disposed on the inner wall of the connector body 50. The protrusion 521 protrudes towards the center of the connector body 50. Optionally, the protrusion 521 includes, but is not limited to, a protrusion, a bump, or a bulge. The second locking portion 33 includes a guide groove 331 and a locking groove 332. Optionally, the guide groove 331 and the locking groove 332 each penetrate the sidewall of the intermediate connecting sleeve 30, for example, along the thickness direction of the sidewall of the intermediate connecting sleeve 30. Of course, they can both be configured as blind grooves, which are not specifically limited here. One end of the guide groove 331 communicates with the locking groove 332, and the other end of the guide groove 331 extends axially along Z to the end face of the intermediate connecting sleeve 30 facing away from the cable 10. The locking groove 332 is disposed circumferentially around the intermediate connecting sleeve 30. Both the guide groove 331 and the locking groove 332 are slidably engaged with the protrusion 521. Thus, when each of the first locking parts 52 and each of the second locking parts 33 are locked in place, the end of the protrusion 521 is aligned with the end of the guide groove 331 along the axial direction Z, causing at least one of the intermediate connecting sleeve 30 and the connector body 50 to move along the axial direction Z. The protrusion 521 will then enter the guide groove 331. Then, at least one of the intermediate connecting sleeve 30 and the connector body 50 will rotate. The rotation angle can be set according to actual needs, as long as the protrusion 521 enters the locking groove 332 from the guide groove 331, thereby effectively preventing the intermediate connecting sleeve 30 from detaching from the connector body 50 along the axial direction Z. Because the locking groove 332 and the protrusion 521 have tight, large-area contact, and the inner wall of the connector body 50 is fitted over the intermediate connecting sleeve 30, the inner wall of the connector body 50 and the outer wall of the intermediate connecting sleeve 30 have tight and large-area contact. Therefore, there is extremely low contact resistance and stable impedance between the connector body 50 and the intermediate connecting sleeve 30.

[0055] The disassembly action of the first locking part 52 and the second locking part 33 is the opposite of the locking action of the first locking part 52 and the second locking part 33, and will not be described in detail here.

[0056] Based on the aforementioned embodiment, a positioning recess 333 is provided on the side wall of the locking groove 332 away from the cable 10. The positioning recess 333 is recessed in a direction away from the cable 10, and the positioning recess 333 is positioned and engaged with the protrusion 521. When the intermediate connecting sleeve 30 and the connector body 50 are combined, after the protrusion 521 enters the locking groove 332, the protrusion 521 enters the positioning recess 333, which can prevent the protrusion 521 from dislodging from the locking groove 332 and the guide groove 331 due to rotation of either the intermediate connecting sleeve 30 or the connector body 50, thereby improving the connection stability between the intermediate connecting sleeve 30 and the connector body 50.

[0057] For example, all the first locking portions 52 are arranged at equal intervals along the circumferential direction of the connector body 50 on the inner wall of the connector body 50. All the second locking portions 33 are arranged at equal intervals along the circumferential direction of the intermediate connecting sleeve 30.

[0058] Taking the first locking part 52 and the second locking part 33 as four examples, rotating the intermediate connecting sleeve 30 by, for example, 45° can separate or lock the replaceable component from the connector body 50.

[0059] Please see Figures 3 to 5 For example, the coaxial connector also includes an insulating component 60. The insulating component 60 is connected between the outer wall of the second inner conductor 20 and the inner wall of the connector body 50. Both the second inner conductor 20 and the connector body 50 are tightly fitted with the insulating component 60. On the one hand, the insulating component 60 provides insulation, effectively preventing short circuits caused by conduction between the second inner conductor 20 and the connector body 50; on the other hand, the insulating component 60 provides support, thereby improving the stability of the second inner conductor 20 on the connector body 50.

[0060] Please see Figures 3 to 5Based on the aforementioned embodiments, the insulating component 60 includes a first insulating sleeve 61 and a second insulating sleeve 62. The first insulating sleeve 61 is fixedly attached to the second inner conductor 20. The second insulating sleeve 62 connects the first insulating sleeve 61 and the connector body 50. The outer wall of the first insulating sleeve 61 is tapered, and the distance S between the outer wall of the first insulating sleeve 61 and the central axis of the second inner conductor 20 increases in the direction closer to the cable 10. In other words, the outer wall of the first insulating sleeve 61 forms an angle with the central axis of the second inner conductor 20. That is, the distance S between the outer wall of the first insulating sleeve 61 and the inner wall of the connector body 50 decreases in the direction closer to the cable 10. Thus, when the second insulating sleeve 62 is inserted into the space between the outer wall of the first insulating sleeve 61 and the connector body 50 in the direction closer to the cable 10, the outer wall of the first insulating sleeve 61 will be gradually compressed by the second insulating sleeve 62, thereby improving the connection stability of the insulating component 60, the connector body 50, and the second inner conductor 20.

[0061] Based on the aforementioned embodiments, the coaxial connector further includes a second sealing ring 70. The second sealing ring 70 includes, but is not limited to, an O-ring. The second sealing ring 70 is connected between the outer wall of the second insulating sleeve 62 and the inner wall of the connector body 50. On one hand, the compression of the second sealing ring 70 provides a sealing effect; on the other hand, the second sealing ring 70 increases separation resistance, thereby improving the connection stability between the connector body 50, the insulating component 60, and the second inner conductor 20.

[0062] Please see Figure 3 and Figure 5 Based on the aforementioned embodiment, a second mounting groove 621 is provided on the outer side wall of the second insulating sleeve 62. The second sealing ring 70 is installed in the second mounting groove 621.

[0063] Please see Figure 3 Based on the aforementioned embodiment, the inner wall of the connector body 50 is provided with a positioning step 53. The insulating component 60 abuts against the positioning step 53 along the axial direction Z. Specifically, the second insulating sleeve 62 abuts against the positioning step 53 along the axial direction Z. The positioning step 53 is located on the side of the second insulating sleeve 62 facing the cable 10, and can restrict the movement of the second insulating sleeve 62 toward the cable 10.
