[0020] The following description provides many different embodiments or examples for implementing different features of the present application. The components and arrangements described in the following specific examples are only used to simplify the present application and are only used as examples, not to limit the present application.

[0021] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application for which protection is claimed, but merely represents the selected embodiments of the present application.

[0022] In this application, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral one; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to the specific circumstances. In addition, the terms "first", "second", "third", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0023] In the present application, unless otherwise clearly specified and limited, a first feature being above or below a 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 being in contact through another feature between them. Moreover, a first feature being above, above, and above a second feature includes the first feature being directly above and obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being below, below, and below a second feature includes the first feature being directly below and obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0024] In the prior art, the connector needs to be rotated when installed in the cabinet. When wiring, not only does the signal need to change 90 degrees, but it also needs to be able to rotate 360 ​​degrees along the cable axis. The existing connector will drive the cable connected to it to rotate during the rotation process, resulting in poor contact between the cable and the connector, causing problems such as interruption or instability in signal transmission. Usually, a spring is used to maintain the connection between two adjacent inner conductors, but the connector is used frequently, and the spring will scratch the inner wall of the inner conductor during the expansion and contraction process. In addition, the installation method of the spring on the inner conductor will also affect the structure of the inner conductor, and it is inconvenient to install and replace. The existing connector cannot be locked at any position during the rotation process, and can only rotate in one direction.

[0025] The purpose of the present invention is to provide a rotatable radio frequency coaxial connector to solve the above technical problems existing in the prior art, such as Figure 1-Figure 23 As shown, it mainly includes the following contents: The present application provides a rotatable radio frequency coaxial connector, comprising: The first outer conductor 10 includes a transverse outer conductor 11 and a vertical outer conductor 12. The transverse outer conductor 11 and the vertical outer conductor 12 are arranged vertically. The outer conductor along the x direction is the transverse outer conductor 11, and the outer conductor along the y direction is the vertical outer conductor 12. The transverse outer conductor 11 and the vertical outer conductor 12 can be integrally connected by welding, crimping, etc.

[0026] The 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 a cabinet or other components, and the other end is located at the lower end of the vertical outer conductor 12 .

[0027] The second inner conductor 14, the third inner conductor 15 and the retaining assembly 20, the second inner conductor 14 and the third inner conductor 15 are installed in the transverse outer conductor 11, one end of the second inner conductor 14 is plugged with the first inner conductor 13, and the other end of the second inner conductor 14 is electrically connected to the third inner conductor 15 through the retaining assembly 20. Exemplarily, the second inner conductor 14 and the third inner conductor 15 are both 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, wherein the second inner conductor 14 and the third inner conductor 15 are coaxially arranged. One end of the second inner conductor 14 can be connected to the first inner conductor 13 by plugging, and the other end of the second inner conductor 14 is electrically connected to one end of the third inner conductor 15 through the retaining assembly 20.

[0028] One end of the retaining component 20 abuts against the second inner conductor 14, and the other end abuts against the third inner conductor 15. Exemplarily, the retaining component 20 is located between the second inner conductor 14 and the third inner conductor 15, and has conductivity, and is used to always maintain electrical connection between the second inner conductor 14 and the third inner conductor 15, thereby ensuring that the signal can be stably transmitted during the rotation of the connector, wherein the two ends of the retaining component 20 will not damage the inner walls of the second inner conductor 14 and the third inner conductor 15, and are easy to install and remove. Optionally, the retaining component 20 is made of metal material.

[0029] The second outer conductor 30 is rotatably connected to the transverse outer conductor 11 through a rotating member 40. Exemplarily, the rotating member 40 is a bearing, one end of the second outer conductor 30 is connected to one end of the transverse outer conductor 11, the rotating member 40 is located between the second outer conductor 30 and the transverse outer conductor 11, and the rotating member 40 is sleeved on the transverse outer conductor 11, so that the second outer conductor 30 can rotate relative to the transverse outer conductor 11, so that the connector can be rotated in a 360° direction when wiring in the cabinet.

[0030] The locking assembly 50 includes a locking rod 51 and a third elastic member 52. One end of the third elastic member 52 is sleeved on the locking rod 51 and fixedly connected to the locking rod 51. The other end of the third elastic member 52 is fixedly connected to the locking groove. One end of the locking rod 51 is slidably installed in the locking groove 31 of the second outer conductor 30 through the third elastic member 52, that is, the locking rod 51 can slide in the locking groove 31 along the x direction, and the other end is inserted into the insertion groove 111 of the transverse outer conductor 11 to achieve the locking of the connector.

[0031] The locking rod 51 has a first position and a second position relative to the locking groove 31, wherein the first position is that the locking rod 51 can slide in the locking groove 31 and is located in the insertion groove 111. In the present application, the first direction C1 and the second direction C2 are opposite, and if the first direction C1 is clockwise, the second direction C2 is counterclockwise. When the locking rod 51 is located at the first position, the first outer conductor 10 can rotate relative to the second outer conductor 30 along the first direction C1. When the first outer conductor 10 rotates to a preset position, due to the cooperation between the locking rod 51 and the insertion groove 111, the first outer conductor 10 remains in the current position and cannot rotate along the second direction C2. When the locking rod 51 needs to be rotated from the first direction C1 to the second direction C2, the locking rod 51 is toggled to switch the locking rod 51 from the first position to the second position. When the locking rod 51 is in the second position, the end of the locking rod 51 is away from the insertion slot 111, and the locking rod 51 is fixed in the locking slot 31. The first outer conductor 10 can be rotated along the second direction C2 relative to the second outer conductor 30. When rotated to the preset position, the locking rod 51 can be toggled to insert the locking rod 51 into the insertion slot 111, so that the first outer conductor 10 cannot rotate along the C2 direction.

[0032] In some optional embodiments, the locking rod 51 can also be switched from the second position to the first position. The connector of the present application can achieve 720° rotation, that is, 360° rotation along the first direction C1 and the second direction C2 respectively, which facilitates the smooth installation of the connector in the cabinet through rotation.

[0033] In some optional embodiments, the end of the second outer conductor 30 is fixedly connected to the cable. When the connector can rotate itself while keeping the cable stationary, the normal transmission of the cable signal is ensured.

[0034] Therefore, the present application provides a rotatable radio frequency coaxial connector. The first outer conductor 10 and the second outer conductor 30 are connected by a rotating member 40, enabling a relative rotation of 720° between the first outer conductor 10 and the second outer conductor 30. When the connector is routed in the cabinet, the position of the cable can be kept unchanged, and only the connector needs to be rotated, without the need for major changes to the internal structure of the cabinet to complete the routing. A locking assembly 50 is provided between the first outer conductor 10 and the second outer conductor 30 to control the rotation direction of the first outer conductor 10. When the first outer conductor 10 rotates to a preset position, it remains locked in the current position. During the rotation of the first outer conductor 10, the cable and the inner conductor may rotate. The holding assembly 20 is used to always keep the second inner conductor 14 and the third inner conductor 15 connected to achieve stable signal transmission. The present application enables the cable to remain stationary after routing is completed, realizes the rotation function through the first outer conductor of the connector, and can lock in a certain direction after rotating to a certain angle to make the signal strongest.

[0035] According to some optional embodiments, the locking groove 31 includes a first position groove 311 and a second position groove 312. The first position groove 311 penetrates the locking end 32 along the axial direction of the second outer conductor 30, and the second position groove 312 extends along the radial direction of the second outer conductor 30 and communicates with the first position groove 311.

[0036] In the above solution, a step is formed on the outer wall of the second outer conductor 30, which is opposite to the end of the transverse outer conductor 11, and this step is the locking end 32. The first position groove 311 penetrates the surface of the second outer conductor 30 in the radial direction, and the second position groove 312 is formed on the outer wall of the second outer conductor 30 and communicates with the first position groove 311. The included angle between the axis of the first position groove 311 and the axis of the second position groove 312 is an acute angle, so that the locking groove 31 forms a "卜" shape, making it difficult for the locking rod 51 to slide out when it is located in the second position groove 312. The locking rod 51 is slidably installed in the first position groove 311 through a third elastic member 52 to lock the rotation of the first outer conductor 10. The locking rod 51 can also be toggled to rotate in the first position groove 311 and rotate to be partially fixed in the second position groove 312 to realize the rotation of the first outer conductor 10 in the second direction.

[0037] By setting the first position slot 311 and the second position slot 312, during the rotation of the connector, it is only necessary to move the locking rod 51 to the corresponding first position slot 311 or the second position slot 312 to realize the rotation of the first outer conductor 10 in different directions, so that the connector can be suitable for different types of cabinet structures, wiring can be completed therein, and signal transmission is stable during the rotation process.

[0038] According to some optional embodiments, a locking portion 53 is provided on the outer wall of the locking rod 51, and a portion of the locking portion 53 extends out of the locking groove 31, wherein the locking portion 53 can be slidably switched from the first position groove 311 to the second position groove 312 for fixing; when the locking rod 51 is in the first position relative to the locking groove 31, the locking portion 53 is located in the first position groove 311; when the locking rod 51 is in the second position relative to the locking groove 31, the locking portion 53 is located in the second position groove 312.

[0039] In the above scheme, the locking portion 53 is rod-shaped. In some optional embodiments, a mounting hole is provided on the outer wall of the locking rod 51, one end of the locking portion 53 is inserted into the mounting hole and connected to the locking rod 51, and the other end extends out of the locking groove 31 and is located outside the second outer conductor 30, so that the operator can operate and dial it from the outside. When the locking rod 51 slides in the first position groove 311, the locking portion 53 is perpendicular to the first position groove 311, and can guide the locking rod 51 to slide in the first position groove 311 without rotating, thereby ensuring that the first outer conductor 10 rotates along the set direction. When the locking rod 51 needs to be converted from the first position to the second position, the locking portion 53 is dialed, and the locking rod 51 rotates in the first position groove 311, driving the locking portion 53 to rotate and embed into the second position groove 312 to remain fixed.

[0040] In some optional embodiments, the locking rod 51 and the locking portion 53 are detachably connected, which facilitates the installation and removal of the locking rod 51 in the locking groove 31 and also facilitates the installation and replacement of the locking portion 53 .

[0041] According to some optional embodiments, the end of the locking rod 51 includes a rotating surface 511 and a stop surface 512, the rotating surface 511 cooperates with the insertion slot 111 to allow the first outer conductor 10 to rotate in a first direction, and the stop surface 512 cooperates with the insertion slot 111 to limit the first outer conductor 10 from rotating in a second direction.

[0042] According to some optional embodiments, there are multiple insertion slots 111, and the multiple insertion slots 111 are distributed at circumferential intervals along the end of the transverse outer conductor 11. The locking rod 51 can be inserted into any insertion slot 111 as needed, wherein the insertion slot 111 is conical.

[0043] In the above scheme, if Fig.10As shown, the locking rod 51 is cylindrical, and the end of the locking rod 51 close to the insertion slot 111 has a rotating surface 511 that rotates with the insertion slot 111. The rotating surface 511 is a beveled surface that cooperates with the conical surface of the insertion slot 111. The abutting surface 512 is a cylindrical surface corresponding to the beveled surface. Under the action of external force, the rotating surface 511 rotates with the insertion slot 111 and can only rotate along the rotating surface 511, such as only rotating along the first direction. The abutting surface 512 abuts against the conical surface of the insertion slot 111, so that the first outer conductor 10 cannot rotate in the second direction; specifically, when the external force drives the locking rod 51 to rotate in the first direction, the rotating surface 511 contacts the conical surface of the insertion groove 111. Since the angles of the two bevels match, sliding friction is generated on the contact surfaces of the two, allowing the locking rod 51 to rotate in the first direction. The geometric design of the beveled surface of the rotating surface 511 may cause the locking rod 51 to have a certain displacement in the x direction, but due to the structural tolerance or the existence of the third elastic member, this displacement is allowed, so that the locking rod 51 can rotate smoothly. When the external force drives the locking rod 51 to rotate in the opposite direction (i.e., rotate in the second direction), the abutting surface 512 contacts the inner wall of the insertion groove 111. When the abutting surface 512 is a cylindrical surface or a rectangular surface perpendicular to the insertion groove 111, the contact area between the abutting surface 512 and the conical surface of the insertion groove 111 will increase or form geometric interference. At this time, the tangential force of the reverse rotation is converted into normal pressure, the friction force increases sharply, and even a self-locking effect is triggered, completely preventing rotation.

[0044] Through such an arrangement, when the first outer conductor 10 rotates in a first direction, the locking rod 51 can rotate in cooperation with the insertion slot 111 through the rotating surface 511, and when the rotation stops, the abutting surface 512 cooperates with the insertion slot 111 to achieve locking, thereby preventing the first outer conductor 10 from rotating in the opposite direction. Due to the arrangement of multiple insertion slots 111, the first outer conductor 10 can be locked at any position.

[0045] According to some optional embodiments, the inner wall of the transverse outer conductor 11 is provided with a first slide rail 112, which is an annular closed ring, and the outer wall of the second outer conductor 30 is provided with a second slide rail 313, which is an annular closed ring. The position of the first slide rail 112 is arranged corresponding to the position of the second slide rail 313, so that the interval between the first outer conductor 10 and the second outer conductor 30 remains unchanged, and the volume of the connector is not affected. The first slide rail 112 and the second slide rail 313 define a rotation channel 314, and the rotating member 40 is slidably installed in the rotation channel 314 to realize the rotation of the first outer conductor 10 relative to the second outer conductor 30.

[0046] According to some optional embodiments, when the locking rod 51 is located at the second position, the first outer conductor 10 can rotate in the first direction relative to the second outer conductor 30. In the above scheme, when the locking portion 53 on the locking rod 51 is located in the second position slot 312, the locking rod 51 is away from the insertion slot 111, and there is no mutual interference between the locking rod 51 and the insertion slot 111. The first outer conductor 10 can rotate in the second direction relative to the second outer conductor 30, and can also rotate in the first direction relative to the second outer conductor 30, so that the connector can be quickly rotated in different directions.

[0047] According to some optional embodiments, the retaining assembly 20 includes a mounting seat 21, which is installed in the mounting cavity 141 of the second inner conductor 14, one end of the mounting seat 21 abuts against the first accommodating groove 142 of the second inner conductor 14 through the first retaining member 22, and the other end of the mounting seat 21 abuts against the second accommodating groove 151 of the third inner conductor 15 through the second retaining member 23, wherein at least one of the first retaining member 22 and the second retaining member 23 is connected to the mounting seat 21 through the first elastic member 221, and a plurality of support members 24 are arranged on the outer wall of the mounting seat 21, and the support members 24 abut against the inner wall of the second inner conductor 14.

[0049] Exemplarily, the second inner conductor 14 is provided with a mounting cavity 141 along its axial direction, and the mounting cavity 141 penetrates one end of the second inner conductor 14 adjacent to the third inner conductor 15. The retaining assembly 20 and one end of the third inner conductor 15 are located in the mounting cavity 141, and one end of the third inner conductor 15 is gap-matched with the inner wall of the mounting cavity 141 around it. The retaining assembly 20 includes a mounting seat 21, which is mounted in the mounting cavity 141 of the second inner conductor 14, one end of the mounting seat 21 abuts against the first receiving groove 142 of the second inner conductor 14 through the first retaining member 22, and the other end of the mounting seat 21 abuts against the second receiving groove 151 of the third inner conductor 15 through the second retaining member 23. In some optional embodiments, the 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 retaining member 22 matches the shape of the first receiving groove 142, so that the first retaining member 22 can be more stably abutted 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 retaining member 23 matches the shape of the second receiving groove 151 , so that the second retaining member 23 can abut more stably in the second receiving groove 151 .

[0050] In some optional embodiments, a first accommodating groove 142 is provided on the cavity wall of the installation cavity 141 of the second inner conductor 14, and the outer wall of the first retaining member 22 can be fixedly connected to the first accommodating groove 142 by means of snap-fitting, plug-in, splicing, etc., and the first retaining member 22 is retained in the first accommodating groove 142 without moving.

[0051] Among them, at least one of the first retaining member 22 and the second retaining member 23 is connected to the mounting seat 21 through the first elastic member 221, and a plurality of supporting members 24 are arranged on the outer wall of the mounting seat 21, and the supporting members 24 abut against the inner wall of the second inner conductor 14, and the plurality of supporting members 24 are evenly distributed on the outer wall of the supporting members 24 at intervals, so that the support for the mounting seat 21 is more stable. In some optional embodiments, the supporting members 24 can be distributed in one circle, two circles, etc. along the circumference of the outer wall of the mounting seat 21. When the supporting members 24 are distributed in multiple circles on the outer wall of the mounting seat 21, the supporting members 24 on two adjacent circles are staggered.

[0052] Optionally, the first elastic member 221 is a spring.

[0053] Specifically, at least one of the first retaining member 22 and the second retaining member 23 is connected to the mounting seat 21 through the first elastic member 221, including three situations: In the first case, only the first retaining member 22 is connected to the mounting seat 21 through the first elastic member 221, and the second retaining member 23 is fixedly connected to the second receiving groove 151. In the present application, the initial state of the first elastic member 221 is a compressed state. When pressure is applied to the first retaining member 22, the support member 24 can abut 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 be driven to 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 maintains abutment with the first receiving groove 142, and the support member 24 slides in the direction close to the third inner conductor 15, providing the mounting seat 21 and the first elastic member 221 with a moving direction and a supporting force, preventing the first elastic member 221 from shaking, thereby ensuring that the second inner conductor 14 and the third inner conductor 15 are always connected through the retaining assembly 20, and realizing continuous signal transmission.

[0054] In the second case, only the second retaining member 23 is connected to the mounting seat 21 through the first elastic member 221, the first retaining member 22 is fixedly connected to the first receiving groove 142, and the initial state of the first elastic member 221 is a compressed state, exerting pressure on 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 be driven 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 second retaining member 23 always remains in contact with the second receiving groove 151, and the supporting member 24 can be stationary relative to the inner wall of the second inner conductor 14, providing support force to the mounting seat 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.

[0055] In the third case, the first retaining member 22 is connected to the mounting seat 21 through the first elastic member 221, and the second retaining member 23 is also connected to the mounting seat 21 through the first elastic member 221. The initial state of the first elastic member 221 is a compressed state, and pressure is applied 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 external force, the third inner conductor 15 connected thereto will also be driven to 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 accommodating groove 142, and the second retaining member 23 abuts against the second accommodating groove 151, thereby achieving a stable connection between the second inner conductor 14 and the third inner conductor 15, and stable transmission of signals.

[0056] Therefore, the present application provides a rotatable radio frequency coaxial connector, including a first inner conductor 13, a second inner conductor 14, and a third inner conductor 15, wherein one end of the second inner conductor 14 is plugged into the first inner conductor 13, and the other end is connected to the third inner conductor 15 through a retaining assembly 20. Specifically, one end of the retaining assembly 20 is connected to the second inner conductor 14 through a first retaining member 22, and the other end is connected to the third inner conductor 15 through a second retaining member 23. The first retaining member 22 and / or the second retaining member 23 are connected to the mounting seat 21 through a first elastic member 221. Under the pressure of the first elastic member 221, the first retaining member 22 and the second retaining 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 to the mounting seat 21, thereby ensuring the consistency of the direction of the pressure of the first elastic member 221 and reducing the pressure loss. By setting the retaining component 20, when the cable moves, the second inner conductor 14 and the third inner conductor 15 are always in good contact, the signal transmission is stable, and the retaining component 20 will not scratch the inner walls of the second inner conductor 14 and the third inner conductor 15, which is convenient for installation and disassembly.

[0057] According to some optional embodiments, a mounting groove 211 is provided on the outer wall of the mounting seat 21, and one end of the support member 24 is rotatably mounted in the mounting groove 211 via a rotating shaft 241, and the rotating shaft 241 is detachably mounted in the mounting groove 211, so as to facilitate its installation and removal. In the present application, when there are multiple support members 24, one support member 24 is correspondingly provided with a rotating shaft 241; the rotation direction is the x direction, and in the rotation direction of the support member 24, both sides of the support member 24 are respectively connected to the inner wall of the mounting groove 211 via the second elastic member 242.

[0058] In some optional embodiments, along the x-axis direction, receiving grooves 2111 are respectively provided on the inner walls of the installation groove 211 that are relatively distributed, and one end of the second elastic member 242 located on both sides of the support member 24 is fixedly installed in the receiving groove 2111, and the other end is fixedly connected to the side wall of the support member 24.

[0059] In some optional embodiments, a third guide surface 1411 is provided on the cavity wall of the installation cavity 141 close to the third inner conductor 15 , and the third guide surface 1411 is an inclined surface.

[0060] 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.

[0061] During the installation of the connector, when the retaining assembly 20 is assembled into the second inner conductor 14, the end of the support member 24 first abuts against the third guide surface 1411. At this time, the support member 24 is subjected to the abutting force of the third guide surface 1411, and the support member 24 swings in the opposite direction of the direction of entering the second inner conductor 14. At this time, the support member 24 slides into the preset position in the installation cavity 141 along the third guide surface 1411. In the present application, through the provision of the third guide surface 1411, the support member 24 can be smoothly installed into the installation cavity 141 under the guidance of the third guide surface 1411. After the support member 24 passes through the third guide surface 1411, it will return to the 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, so that the retaining assembly 20 can be more stably installed in the installation cavity 141.

[0062] In some optional embodiments, the height of the support member 24 along the y direction can be extended and retracted, such as the support member 24 includes a first support member and a second support member, and the first support member and the second support member are connected by a spring. When the retaining assembly 20 or the second inner conductor 14 is displaced along the y direction, the support member 24 can be extended and retracted in the y direction to always maintain contact with the installation cavity 141.

[0063] In some optional 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 seat 21 .

[0064] According to some optional embodiments, a first positioning groove is provided on the inner wall of the second inner conductor 14 , and one end of the support member 24 away from the mounting seat 21 is fixedly abutted in the first positioning groove.

[0065] In the above solution, the first positioning groove may be a groove or a slide groove, and the slide groove is extended along the x direction.

[0066] When the retaining assembly 20 is in the first case, only the first retaining member 22 is connected to the mounting seat 21 through the first elastic member 221, the second retaining member 23 is fixedly connected to the mounting seat 21, and the end of the second retaining member 23 is abutted or fixedly connected to the second receiving groove 151. At this time, the first positioning groove is a slide groove. When the connector is in use, when the cable is rotated or pulled by external force, the third inner conductor 15 connected thereto will also be driven to 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, the end of the support member 24 is in contact with the slide groove, and slides along the slide groove toward the direction of the third inner conductor 15, ensuring that the pressure applied by the first elastic member 221 to the second retaining member 23 remains unchanged in magnitude and direction, thereby keeping the second retaining member 23 connected to the second receiving groove 151, and realizing continuous signal transmission.

[0067] When the retaining assembly 20 is in the second case, only the second retaining member 23 is connected to the mounting seat 21 through the first elastic member 221, the first retaining member 22 is fixedly connected to the mounting seat 21, and the first retaining member 22 is abutted / fixedly connected to the first receiving groove 142. At this time, the first positioning groove can be a slide groove or a groove. 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 be driven to 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 end of the support member 24 abuts against the groove or slides along the slide groove, thereby ensuring that the pressure applied by the second retaining member 23 to the first retaining member 22 remains unchanged in magnitude and direction, thereby making the second inner conductor 14 and the third inner conductor 15 always connected through the retaining assembly 20.

[0068] When the retaining assembly 20 is in the third case, the first retaining member 22 is connected to the mounting seat 21 through the first elastic member 221, and the second retaining member 23 is also connected to the mounting seat 21 through the first elastic member 221. At this time, the first positioning groove can be a slide groove or a groove. When the cable is rotated or pulled by an external force, the third inner conductor 15 connected thereto will also be driven to 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 slide groove. 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, thereby achieving a stable connection between the second inner conductor 14 and the third inner conductor 15 and a stable transmission of signals.

[0069] 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 fixed groove 231 of the second retaining member 23, and the first elastic member 221 is used to enable the second retaining member 23 to slide in the telescopic groove 212.

[0070] 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 retaining member 22, and the first elastic member 221 is used to enable the first retaining member 22 to slide in the telescopic groove 212.

[0071] In the above scheme, the first retaining member 22 and the second retaining member 23 respectively move along the telescopic groove 212 under the pressure of the first elastic member 221, thereby maintaining abutment with the first accommodating groove 142 and the second accommodating groove 151, ensuring the connection between the second inner conductor 14 and the third inner conductor 15, and realizing continuous transmission of signals.

[0072] In the present 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 be telescoped along the telescopic groove 212, and the telescopic groove 212 will provide support force and telescopic direction for the first elastic member 221, thereby ensuring the connection between the second inner conductor 14 and the third inner conductor 15, and will not scratch the inner wall of the second inner conductor 14. At the same time, the first elastic member 221 can be installed externally before entering the second inner conductor 14, 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, thereby reducing damage to both and the impact on the transmitted signal.

[0073] According to some optional embodiments, when the first retaining member 22 and the second retaining member 23 have the same structure, the structure of the second retaining member 23 is taken as an example for explanation. The second retaining member 23 includes an abutting end abutting against the second accommodating groove 151 and a telescopic end connected to the mounting seat 21. The outer wall of the telescopic end of the second retaining member 23 located in the telescopic groove 212 is provided with a stopper 232. Preferably, the stopper 232 in the present application can be set to 1, 2, 3, etc., which is not limited here. In the present application, it is preferably two, and the two stopper 232 are symmetrically arranged along the axis of the second retaining member 23. Optionally, the stopper 232 is a stopper block, and the cross section of the stopper 232 is approximately trapezoidal. The stopper 232 extends along the circumferential direction of the second retaining member 23, and a first guide surface 2321 is provided on a side of the stopper 232 close to the first retaining member 22. The first guide surface 2321 is connected to the end surface of the telescopic end of the second retaining member 23, and the first guide surface 2321 is an inclined surface. The stopper 232 can be installed in the telescopic slot 212 through the first guide surface 2321. A stop surface 2322 is provided on a side of the stopper 232 opposite to the first guide surface 2321. When the second retaining member 23 slides in the telescopic slot 212 to the end of the mounting seat 21, the stop surface 2322 can abut against the step on the inner wall of the telescopic slot 212 to prevent the second retaining member 23 from sliding out of the telescopic slot 212.

[0074] 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.

[0075] 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.

[0076] 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.

[0077] 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 .

[0078] 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 .

[0079] 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.

[0080] According to some optional embodiments, an insertion hole 131 is provided 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 piece 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, and the second positioning groove 132 and the telescopic positioning piece 143 are engaged with each other, so that the connection between the second inner conductor 14 and the first inner conductor 13 is more stable, thereby 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 first inner conductor 13 along the insertion hole 131, the ball in the telescopic positioning member 143 will enter the second positioning groove 132 under the action of the spring, and vibration or sound will be generated at this time. The operator can judge that the second inner conductor 14 is installed in place in the first inner conductor 13 through the sensed vibration and sound, and cancel the thrust applied to the second inner conductor 14 to avoid excessive thrust and damage to the second inner conductor 14 and the first inner conductor 13.

[0081] According to some optional embodiments, the insertion hole 131 has a second guide surface 133, the second guide surface 133 is an inclined surface, and the shape of the insertion hole 131 is a trumpet shape. When the second inner conductor 14 is plugged 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 guide surface 133.

[0082] In some optional embodiments, the shape of the insertion end of the second inner conductor 14 matches 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.

[0083] According to some optional embodiments, an interference groove 134 is provided on the second guide surface 133. A plurality of interference grooves 134 can be provided along the x direction and are spaced apart on the second guide surface 133. An interference protrusion 144 is provided at a corresponding position of the outer wall of the insertion end of the second inner conductor 14. The interference protrusion 144 cooperates with the interference groove 134 to achieve a stable connection between the first inner conductor 13 and the second inner conductor 14, thereby preventing the second inner conductor 14 from detaching from the first inner conductor 13 and ensuring stable signal transmission.

[0084] In the present application, since the first inner conductor 13, the second inner conductor 14 and the third inner conductor 15 are all installed in In the first outer conductor 10 , the first outer conductor 10 rotates relative to the second outer conductor 30 , wherein the first inner conductor 13 and the second inner conductor 14 can be fixedly connected or rotatably connected.

[0085] 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 apart on the circumference of the inner wall of the insertion hole 131, the telescopic positioning member 143 is embedded in the groove, and the interference groove 134 is a plurality of grooves spaced apart along the circumference of the second guide surface 133, not an annular groove, and the corresponding interference protrusion 144 is also a convex block spaced apart along the circumference of the insertion end of the second inner conductor 14, and the interference protrusion 144 is engaged with the interference groove 134. Such an arrangement can limit the first inner conductor 13 from rotating relative to the second inner conductor 14 and moving in the x direction, and when the first outer conductor 10 rotates, the first inner conductor 13 and the second inner conductor 14 rotate with the first outer conductor 10 at the same time, and the first inner conductor 13 and the second inner conductor 14 still maintain a close electrical connection.

[0086] When the first inner conductor 13 and the second inner conductor 14 are connected in rotation, the second positioning groove 132 is an annular closed groove arranged on the circumference of the inner wall of the insertion hole 131, and 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 arranged on the circumference of the second guide surface 133, and the corresponding interference protrusion 144 is an annular protrusion, and 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 will not move in the x direction, so that when the first outer conductor 10 rotates, the first inner conductor 13 can rotate relative to the second inner conductor 14, and the second inner conductor 14 does not need to rotate, and the first inner conductor 13 will not be separated from the second inner conductor 14, avoiding the instability of signal transmission caused by the simultaneous rotation of multiple components.

[0087] According to some optional embodiments, the cable welding sleeve 70 is connected to the cable by welding, the cable welding sleeve 70 and the third outer conductor 60, the third outer conductor 60 is sleeved on the cable welding sleeve 70, and the third outer conductor 60 and the second outer conductor 30 can be connected by crimping or threading. A limiting groove is formed between the inner wall of the second outer conductor 30 and the end of the third outer conductor 60, and the end of the cable welding sleeve 70 is located in the limiting groove, so that the cable welding sleeve 70 is fixed in the connector.

[0088] In some optional embodiments, along the x direction, the length of the cable welding sleeve 70 is greater than the length of the third outer conductor 60 , which can effectively prevent the third outer conductor 60 from damaging the cable welding sleeve 70 during the tightening process.
