[0036] The following description provides many different embodiments or examples for implementing different features of the present application. The elements and arrangements described in the following specific examples are only used to concisely express the present application, and they are only examples and are not intended to limit the present application.
[0037] To make the objectives, technical solutions and advantages of the embodiments of this application clearer, the following will clearly and completely describe the technical solutions in the embodiments of this application with reference to the accompanying drawings in the embodiments of this application. Apparently, the described embodiments are some, but not all, of the embodiments of this application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in this application without creative efforts shall fall within the scope of protection of this application. Therefore, the detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of this application claimed, but merely represents selected embodiments of this application.
[0038] In this application, unless otherwise clearly specified or defined, terms such as "install", "connect", "couple", "fix" shall be construed in a broad sense. For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the internal communication of two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances. In addition, terms such as "first", "second", "third", etc. are only used for descriptive distinction and cannot be construed as indicating or implying relative importance.
[0039] In this application, unless otherwise clearly specified or defined, the first feature being above or below the second feature may include the first and second features being in direct contact, or may include the first and second features not being in direct contact but in contact through additional features therebetween. Moreover, the first feature being above, on top of and over the second feature includes the first feature being directly above and obliquely above the second feature, or merely indicating that the first feature has a higher horizontal height than the second feature.

[0040] In the prior art, when a connector is installed in a cabinet, it needs to be rotated. When wiring, not only does the signal need to be changed by 90 degrees, but also it needs to be rotated 360 degrees along the axis of the cable. During the rotation of the existing angled connector, it will drive the cable connected to it to rotate, resulting in poor contact between the cable and the connector, causing problems such as signal transmission interruption or instability. Usually, a spring is used to maintain the connection between two adjacent inner conductors. However, since the connector is used frequently, the spring will scratch the inner wall of the inner conductor during the process of expansion and contraction, and the installation method of the spring on the inner conductor will also affect the structure of the inner conductor, and is not convenient for installation and replacement, etc.
[0041] In view of this, the object of the present invention is to provide a bent radio frequency coaxial connector to solve the above technical problems existing in the prior art, such as Figures 1 - 12 As shown, it includes:
[0042] The bent radio frequency coaxial connector is usually in an L shape and includes an outer conductor and an inner conductor. The outer conductor includes a transverse outer conductor 11 and a vertical outer conductor 12, and the transverse outer conductor 11 and the vertical outer conductor 12 are vertically arranged. The outer conductor in the x direction is the transverse outer conductor 11, and the outer conductor in the y direction is the vertical outer conductor 12. The transverse outer conductor 11 and the vertical outer conductor 12 can be integrally formed and connected by means such as welding and crimping.
[0043] A first inner conductor 13 is installed in the vertical outer conductor 12. The first inner conductor 13 is inserted into the vertical outer conductor 12 along the y direction. One end of the first inner conductor 13 can be plugged into components such as a cabinet, and the other end is located at the lower end of the vertical outer conductor 12.
[0044] A second inner conductor 14, a third inner conductor 15 and a holding assembly 20. The second inner conductor 14 is installed in the transverse outer conductor 11, and one end of the second inner conductor 14 is plugged into the first inner conductor 13, and the other end is electrically connected to the third inner conductor 15 through the holding assembly 20.
[0045] Exemplarily, both the second inner conductor 14 and the third inner conductor 15 are installed in the transverse outer conductor 11 along the x direction. The second inner conductor 14 is located between the first inner conductor 13 and the third inner conductor 15, and the second inner conductor 14 and the third inner conductor 15 are coaxially arranged. One end of the second inner conductor 14 can be movably or fixedly connected to the first inner conductor 13 by plugging, and the other end of the second inner conductor 14 can be movably connected to one end of the third inner conductor 15.
[0046] The holding assembly 20 is located between the second inner conductor 14 and the third inner conductor 15 and has conductivity to keep the second inner conductor 14 and the third inner conductor 15 always electrically connected, thereby ensuring the stable transmission of the connector signal. Optionally, the holding assembly 20 is made of a metal material. Exemplarily, the second inner conductor 14 is provided with an installation cavity 141 along its axial direction, and the installation cavity 141 penetrates through one end of the second inner conductor 14 adjacent to the third inner conductor 15. One end of the holding assembly 20 and the third inner conductor 15 are located in the installation cavity 141, and there is a clearance fit between one end of the third inner conductor 15 and the inner wall of the surrounding installation cavity 141.
[0047] In some optional embodiments, the holding component 20 includes a mounting base 21 which is installed in the mounting cavity 141 of the second inner conductor 14. One end of the mounting base 21 abuts against the first receiving groove 142 of the second inner conductor 14 through a first holding member 22, and the other end of the mounting base 21 abuts against the second receiving groove 151 of the third inner conductor 15 through a second holding member 23. In some optional embodiments, a first receiving groove 142 is provided on the cavity wall of the mounting cavity 141 of the second inner conductor 14, and the shape of the outer wall of the first holding member 22 matches the shape of the first receiving groove 142, so that the first holding member 22 can achieve a more stable abutment in the first receiving groove 142. Similarly, a second receiving groove 151 is provided at the end of the third inner conductor 15, and the shape of the outer wall of the second holding member 23 matches the shape of the second receiving groove 151, so that the second holding member 23 can achieve a more stable abutment in the second receiving groove 151.
[0048] In some optional embodiments, a first receiving groove 142 is provided on the cavity wall of the mounting cavity 141 of the second inner conductor 14, and the outer wall of the first holding member 22 can be fixedly connected to the first receiving groove 142 by means of clamping, plugging, splicing, etc., and the first holding member 22 is held stationary in the first receiving groove 142.
[0049] Wherein, at least one of the first holding member 22 and the second holding member 23 is connected to the mounting base 21 through a first elastic member 221. A plurality of supporting members 24 are provided on the outer wall of the mounting base 21, and the supporting members 24 abut against the inner wall of the second inner conductor 14. The plurality of supporting members 24 are evenly spaced and distributed on the outer wall of the mounting base 21, so that the support for the mounting base 21 is more stable. In some optional embodiments, the supporting members 24 can be distributed in one or two circles along the circumferential direction of the outer wall of the mounting base 21. When the supporting members 24 are distributed in multiple circles on the outer wall of the mounting base 21, the supporting members 24 on adjacent two circles are arranged in a staggered manner.
[0050] Optionally, the first elastic member 221 is a spring.
[0051] Specifically, at least one of the first holding member 22 and the second holding member 23 is connected to the mounting base 21 through a first elastic member 221, including three cases:
[0052] In the first case, only the first retaining member 22 is connected to the mounting base 21 through the first elastic member 221, and the second retaining member 23 is fixedly connected to the second receiving groove 151. In this application, the initial state of the first elastic member 221 is a compressed state. When a pressure is applied to the first retaining member 22, the support member 24 can abut against and slide along the inner wall of the second inner conductor 14. When the connector is in use, when the cable is rotated or pulled by an external force, the third inner conductor 15 connected thereto will also rotate or move away from the second inner conductor 14. At this time, under the pressure applied by the first elastic member 221, the first retaining member 22 always remains in contact with the first receiving groove 142, and the support member 24 slides in the direction close to the third inner conductor 15, providing a moving direction and a supporting force for the mounting base 21 and the first elastic member 221, preventing the first elastic member 221 from shaking, and thus ensuring that the second inner conductor 14 and the third inner conductor 15 are always connected through the retaining assembly 20, realizing the continuous transmission of signals.
[0053] In the second case, only the second retaining member 23 is connected to the mounting base 21 through the first elastic member 221, and the first retaining member 22 is fixedly connected to the first receiving groove 142. The initial state of the first elastic member 221 is a compressed state, applying a pressure to the second retaining member 23. When the connector is in use, when the cable is rotated or pulled by an external force, the third inner conductor 15 connected thereto will also rotate or move away from the second inner conductor 14. At this time, under the pressure applied by the first elastic member 221, the second retaining member 23 always remains in contact with the second receiving groove 151, and the support member 24 can be stationary relative to the inner wall of the second inner conductor 14, providing a supporting force for the mounting base 21 and the first elastic member 221, so that the signal between the second inner conductor 14 and the third inner conductor 15 can be stably transmitted.
[0054] In the third case, the first retaining member 22 is connected to the mounting base 21 through the first elastic member 221, and the second retaining member 23 is also connected to the mounting base 21 through the first elastic member 221. The initial state of the first elastic member 221 is a compressed state, applying pressures to the first retaining member 22 and the second retaining member 23 respectively. When the connector is in use, when the cable is rotated or pulled by an external force, the third inner conductor 15 connected thereto will also rotate or move away from the second inner conductor 14. At this time, the support member 24 abuts against the inner wall of the second inner conductor 14. Under the pressure applied by the first elastic member 221, the first retaining member 22 abuts against the first receiving groove 142, and the second retaining member 23 abuts against the second receiving groove 151, realizing a firm connection between the second inner conductor 14 and the third inner conductor 15 and the stable transmission of signals.
[0055] Therefore, the present application provides a bent radio frequency coaxial connector, which includes a first inner conductor 13, a second inner conductor 14, and a third inner conductor 15. One end of the second inner conductor 14 is inserted into the first inner conductor 13, and the other end is electrically connected to the third inner conductor 15 through a holding assembly 20. Specifically, one end of the holding assembly 20 is connected to the second inner conductor 14 through a first holding member 22, and the other end is connected to the third inner conductor 15 through a second holding member 23. The first holding member 22 and / or the second holding member 23 are connected to a mounting seat 21 through a first elastic member 221. Under the pressure of the first elastic member 221, the first holding member 22 and the second holding member 23 are respectively in contact with the second inner conductor 14 and the third inner conductor 15. At the same time, a support member 24 is provided to abut against the inner wall of the mounting cavity 141, providing a supporting force for the mounting seat 21, ensuring the consistency of the direction of the pressure of the first elastic member 221 and reducing the loss of the pressure. Through the setting of the holding assembly 20, when the connector rotates relative to the cable, the second inner conductor 14 and the third inner conductor 15 are always in good contact, the signal transmission is stable, and the holding assembly 20 will not cause scratches on the inner walls of the second inner conductor 14 and the third inner conductor 15, which is convenient for installation and disassembly.
[0056] According to some optional embodiments, a mounting groove 211 is provided on the outer wall of the mounting seat 21. One end of the support member 24 is rotatably mounted in the mounting groove 211 through a rotating shaft 241, and the rotating shaft 241 is detachably mounted in the mounting groove 211, which is convenient for its installation and disassembly. In the present application, when the number of support members 24 is multiple, one rotating shaft 241 is correspondingly provided for one support member 24; the rotation direction is the x direction. On both sides of the support member 24 in the rotation direction of the support member 24, the support member 24 is respectively connected to the inner wall of the mounting groove 211 through a second elastic member 242.
[0057] In some optional embodiments, receiving grooves 2111 are respectively provided on the relatively distributed inner walls of the mounting groove 211 along the x-axis direction. One ends of the second elastic members 242 located on both sides of the support member 24 are fixedly mounted in the receiving grooves 2111, and the other ends are fixedly connected to the side walls of the support member 24.
[0058] In some optional embodiments, a third guiding surface 1411 is provided on the cavity wall of the mounting cavity 141 close to the third inner conductor 15, and the third guiding surface 1411 is an inclined surface.
[0059] In some optional embodiments, the end of the support member 24 abutting against the inner wall of the second inner conductor 14 is an arc surface. Specifically, the shape of the end of the support member 24 abutting against the inner wall of the second inner conductor 14 matches the shape of the inner wall of the second inner conductor 14.
[0060] During the installation of the connector, when the holding component 20 is being assembled into the second inner conductor 14, the end of the support member 24 first abuts against the third guiding surface 1411. At this time, the support member 24 receives the abutting force from the third guiding surface 1411, and the support member 24 swings in the direction opposite to the direction of entering the second inner conductor 14. Then, the support member 24 slides along the third guiding surface 1411 into a preset position in the installation cavity 141. In this application, through the setting of the third guiding surface 1411, the support member 24 can be smoothly installed into the installation cavity 141 under the guidance of the third guiding surface 1411. After the support member 24 passes through the third guiding surface 1411, it will return to its initial position under the action of the second elastic member 242, and one end of the second elastic member 242 abuts against the installation cavity 141, enabling the holding component 20 to be more firmly installed in the installation cavity 141.
[0061] In some alternative embodiments, the height of the support member 24 in the y direction can be telescopic. For example, the support member 24 includes a first support member and a second support member, which are connected by a spring. When the holding component 20 or the second inner conductor 14 undergoes displacement in the y direction, the support member 24 can be telescopic in the y direction and always remain in contact with the installation cavity 141.
[0062] In some alternative embodiments, the support member 24 is fixedly installed in the installation groove 211, or the support member 24 is fixedly installed on the outer wall of the installation base 21.
[0063] According to some alternative embodiments, a first positioning groove is provided on the inner wall of the second inner conductor 14, and the end of the support member 24 away from the installation base 21 is fixedly abutted in the first positioning groove.
[0064] In the above solution, the first positioning groove can be a groove or a sliding groove, and the sliding groove extends in the x direction.
[0065] When the holding component 20 is in the first case, only the first holding member 22 is connected to the installation base 21 through the first elastic member 221, the second holding member 23 is fixedly connected to the installation base 21, and the end of the second holding member 23 abuts against or is fixedly connected to the second receiving groove 151. At this time, the first positioning groove is a sliding groove. When the connector is in use, when the cable is rotated or pulled by an external force, it will drive the third inner conductor 15 connected to it to rotate or move away from the second inner conductor 14. At this time, under the pressure exerted by the first elastic member 221, the first holding member 22 always remains in contact with the first receiving groove 142, the end of the support member 24 abuts against the sliding groove, and slides along the sliding groove in the direction of the third inner conductor 15, ensuring that the pressure magnitude and direction exerted by the first elastic member 221 on the second holding member 23 remain unchanged, thereby enabling the second holding member 23 to remain connected to the second receiving groove 151 and realizing continuous signal transmission.
[0066] When the holding assembly 20 is in the second case, only the second holding member 23 is connected to the mounting base 21 through the first elastic member 221. The first holding member 22 is fixedly connected to the mounting base 21, and the first holding member 22 abuts / fixedly connects with the first receiving groove 142. At this time, the first positioning groove can be a sliding groove or a groove. When the connector is in use, when the cable is subjected to an external force and rotates or is pulled, it will drive the third inner conductor 15 connected thereto to also rotate or move away from the second inner conductor 14. At this time, under the pressure applied by the first elastic member 221, the second holding member 23 always remains in contact with the second receiving groove 151. The end of the support member 24 abuts against the groove or slides along the sliding groove, thereby ensuring that the pressure magnitude and direction applied by the second holding member 23 to the first holding member 22 remain unchanged, and further enabling the second inner conductor 14 and the third inner conductor 15 to be always connected through the holding assembly 20.
[0067] When the holding assembly 20 is in the third case, the first holding member 22 is connected to the mounting base 21 through the first elastic member 221, and the second holding member 23 is also connected to the mounting base 21 through the first elastic member 221. At this time, the first positioning groove can be a sliding groove or a groove. When the cable is subjected to an external force and rotates or is pulled, it will drive the third inner conductor 15 connected thereto to also rotate or move away from the second inner conductor 14. At this time, the end of the support member 24 abuts against the groove or slides along the sliding groove. Under the pressure applied by the first elastic member 221, the first holding member 22 abuts against the first receiving groove 142, and the second holding member 23 abuts against the second receiving groove 151, realizing a stable connection between the second inner conductor 14 and the third inner conductor 15 and a stable transmission of signals.
[0068] According to some optional embodiments, a telescopic groove 212 is provided at one end of the mounting base 21 close to the third inner conductor 15. One end of the first elastic member 221 is fixedly installed in the telescopic groove 212, and the other end is connected to the fixing groove 231 of the second holding member 23. The first elastic member 221 is used to enable the second holding member 23 to slide in the telescopic groove 212.
[0069] In some optional embodiments, a telescopic groove 212 is provided at one end of the mounting base 21 close to the second inner conductor 14. One end of the first elastic member 221 is fixedly installed in the telescopic groove 212, and the other end is connected to the fixing groove of the first holding member 22. The first elastic member 221 is used to enable the first holding member 22 to slide in the telescopic groove 212.
[0070] In the above solution, the first holding member 22 and the second holding member 23 move along the telescopic groove 212 under the pressure of the first elastic member 221 respectively, and then maintain the abutment with the first receiving groove 142 and the second receiving groove 151, ensuring the connection between the second inner conductor 14 and the third inner conductor 15 and realizing the continuous transmission of signals.
[0071] In this application, by installing one end of the first elastic member 221 in the telescopic groove 212 and the other end in the fixed groove 231, when the third inner conductor 15 rotates or moves, the first elastic member 221 can expand and contract along the telescopic groove 212. The telescopic groove 212 will simultaneously provide a supporting force and a direction for expansion and contraction to the first elastic member 221, ensuring the connection between the second inner conductor 14 and the third inner conductor 15 and not scratching the inner wall of the second inner conductor 14. At the same time, the first elastic member 221 can enter the second inner conductor 14 after being externally installed, which is convenient for installation and has a large operating space. The first elastic member 221 is not directly connected to the second inner conductor 14 or the third inner conductor 15, reducing the damage to both and the influence on the transmitted signal.
[0072] According to some optional embodiments, when the structures of the first holding member 22 and the second holding member 23 are the same, the structure of the second holding member 23 is taken as an example for explanation. The second holding member 23 includes an abutting end abutting against the second receiving groove 151 and a telescopic end connected to the mounting seat 21. A stop portion 232 is provided on the outer wall of the telescopic end of the second holding member 23 located in the telescopic groove 212. Preferably, the stop portion 232 in this application can be set to 1, 2, 3, etc., which is not limited herein. In this application, two are preferred, and the two stop portions 232 are symmetrically arranged along the axis of the second holding member 23. Optionally, the stop portion 232 is a stop block, and the cross-section of the stop portion 232 is approximately trapezoidal. The stop portion 232 extends along the circumferential direction of the second holding member 23, and a first guiding surface 2321 is provided on the side of the stop portion 232 close to the first holding member 22. The first guiding surface 2321 is connected to the end surface of the telescopic end of the second holding member 23, and the first guiding surface 2321 is an inclined surface. The stop portion 232 can be installed in the telescopic groove 212 through the first guiding surface 2321. A stop surface 2322 is provided on the side of the stop portion 232 opposite to the first guiding surface 2321. When the second holding member 23 slides to the end of the mounting seat 21 in the telescopic groove 212, the stop surface 2322 can abut against the step on the inner wall of the telescopic groove 212 to prevent the second holding member 23 from sliding out of the telescopic groove 212.
[0073] In some optional embodiments, a stop groove 213 is provided on the inner wall of the telescopic groove 212, and the stop groove 213 is connected with the telescopic groove 212. The stop groove 213 can be along the y direction, and the stop groove 213 can pass through the outer wall of the mounting seat 21, or it can not pass through the outer wall of the mounting seat 21, and there is no limitation here. The stop portion 232 of the second retaining member 23 is located in the stop groove 213, and can slide and retract along the stop groove 213. When the stop portion 232 moves to a preset position in the stop groove 213, the stop surface 2322 abuts against the inner wall of the stop groove 213, so that the second retaining member 23 is retained in the telescopic groove 212.
[0074] According to some optional embodiments, a contraction groove 2323 is formed on an outer wall of the end of the telescopic end of the second retaining member 23 located in the telescopic groove 212 . The contraction groove 2323 extends along the axial direction of the second retaining member 23 and passes through the end thereof.
[0075] In the above scheme, the contraction groove 2323 is located between two adjacent stoppers 232. The contraction groove 2323 opened on the outer wall of the second retainer 23 is one, two, three, etc., and the present application preferably sets two contraction grooves 2323, and the two contraction grooves 2323 are symmetrically arranged along the axis of the second retainer 23. In the present application, when the second retainer 23 is installed in the mounting seat 21, the slot gap of the contraction groove 2323 becomes smaller, and the end can smoothly enter the telescopic groove 212 of the mounting seat 21.
[0076] According to some optional embodiments, a notch of the first receiving groove 142 is provided with a limiting portion 1421 , and the limiting portion 1421 is used to keep the first retaining member 22 in the first receiving groove 142 .
[0077] In some optional embodiments, the second receiving groove 151 may have the same structure as the first receiving groove 142 . A notch of the second receiving groove 151 may also be provided with a limiting portion 1421 for retaining the second retaining member 23 in the second receiving groove 151 .
[0078] In the above solution, the limiting portion 1421 can be set as a limiting ring that is continuous along the circumference of the slot, or as a limiting block that is spaced apart along the circumference of the slot. The diameter of the limiting opening formed by the limiting portion 1421 is smaller than the maximum size of the cross section of the first retaining member 22, so that the first retaining member 22 will not be separated from the first accommodating slot 142 during the extension and retraction process, thereby ensuring stable transmission of the signal.
[0079] According to some optional embodiments, an insertion hole 131 is formed at the end of the first inner conductor 13, and the insertion hole 131 is arranged along the x direction. A second positioning groove 132 is provided on the inner wall of the insertion hole 131, and the number of the second positioning grooves 132 is not limited. A telescopic positioning member 143 corresponding to the second positioning groove 132 is provided on the outer wall of the end of the second inner conductor 14 inserted into the first inner conductor 13. Through the clamping cooperation between the second positioning groove 132 and the telescopic positioning member 143, the connection between the second inner conductor 14 and the first inner conductor 13 is made more stable, ensuring the stable transmission of signals between the two. Exemplarily, the telescopic positioning member 143 includes a spring and a ball. One end of the spring is fixedly connected to the outer wall of the second inner conductor 14, and the other end is fixedly connected to the ball. When the second inner conductor 14 is inserted into the insertion hole 131 of the first inner conductor 13 in place, the ball in the telescopic positioning member 143 will enter the second positioning groove 132 under the action of the spring. At this time, there will be vibrations or sounds, and the operator can judge that the second inner conductor 14 is installed in place in the first inner conductor 13 by sensing the vibrations and sounds, and cancel the thrust applied to the second inner conductor 14 to avoid excessive application of thrust and causing damage to the second inner conductor 14 and the first inner conductor 13.
[0080] According to some optional embodiments, the insertion hole 131 has a second guiding surface 133, and the second guiding surface 133 is an inclined surface, and the shape of the insertion hole 131 is in a trumpet shape. When the second inner conductor 14 is inserted and installed with the first inner conductor 13, the insertion end of the second inner conductor 14 can quickly and smoothly enter the insertion hole 131 along the second guiding surface 133.
[0081] In some optional embodiments, the shape of the insertion end of the second inner conductor 14 is matched with the shape of the insertion hole 131, so that after the second inner conductor 14 is inserted into the first inner conductor 13, the two can be tightly connected.
[0082] According to some optional embodiments, an interference groove 134 is provided on the second guiding surface 133. The interference grooves 134 can be provided in multiple numbers and are spaced on the second guiding surface 133. An interference protrusion 144 is provided at the corresponding position on the outer wall of the insertion end of the second inner conductor 14. The interference protrusion 144 and the interference groove 134 cooperate to further realize the stable connection between the first inner conductor 13 and the second inner conductor 14, prevent the second inner conductor 14 from detaching from the first inner conductor 13, and ensure the stable transmission of signals.
[0083] In this application, the first inner conductor 13 and the second inner conductor 14 can be fixedly connected or rotatably connected.
[0084] When the first inner conductor 13 and the second inner conductor 14 are fixedly connected, the second positioning groove 132 is a plurality of grooves spaced circumferentially on the inner wall of the insertion hole 131. The telescopic positioning member 143 is embedded in the grooves, and the interference groove 134 is a plurality of grooves spaced circumferentially along the circumferential direction of the second guiding surface 133, not an annular groove. The corresponding interference protrusion 144 is also a protrusion spaced circumferentially along the insertion end of the second inner conductor 14. The interference protrusion 144 is in snap-fit with the interference groove 134. Through such a setting, the rotation of the first inner conductor 13 relative to the second inner conductor 14 and the movement in the x direction can be restricted. When the outer conductor rotates, the first inner conductor 13 and the second inner conductor 14 rotate simultaneously with the outer conductor, and a tight electrical connection is still maintained between the first inner conductor 13 and the second inner conductor 14.
[0085] When the first inner conductor 13 and the second inner conductor 14 are rotatably connected, the second positioning groove 132 is an annular closed groove provided on the inner wall circumference of the insertion hole 131. The telescopic positioning member 143 can rotate circumferentially along the second positioning groove 132. At the same time, the interference groove 134 is an annular groove provided on the circumference of the second guiding surface 133, and the corresponding interference protrusion 144 is an annular protrusion. The interference protrusion 144 can be embedded in the interference groove 134 and rotate circumferentially relative to the interference groove 134. Through such a setting, the first inner conductor 13 and the second inner conductor 14 can rotate, but do not move in the x direction. When the outer conductor rotates, the first inner conductor 13 can rotate relative to the second inner conductor 14, while the second inner conductor 14 does not need to rotate, and the first inner conductor 13 does not detach from the second inner conductor 14, avoiding the instability of signal transmission caused by the simultaneous rotation of multiple components.
