Description

Technical Field

[0001] The present invention relates to the field of radio frequency connectors, and more particularly to a vibration-resistant quick-release radio frequency connector and a method of using the same. Background Art

[0002] As a core component of microwave frequency signal transmission, RF connectors often use mechanical structures to pre-fix multiple plugs into a whole (such as array or matrix combinations) in high-density integration, synchronized connection, or modular rapid deployment scenarios, and achieve one-time docking with the multi-channel interface of the socket to significantly improve installation efficiency and simplify system layout (for example, multi-antenna feeder connection of 5G base stations and RF module integration of phased array radars).

[0003] However, the existing combined RF connection solution has significant defects: on the one hand, in strong vibration environments such as those on vehicles, ships, and aircraft, overall loosening will occur (the connection between the plug and the socket becomes loose due to vibration). If it is not fixed, it is easy to cause overall connection failure and serious signal interruption failure (the signal is completely disconnected). However, the traditional method of fixing with screws is more troublesome and it is not easy to achieve the improvement in installation efficiency mentioned in the previous paragraph. On the other hand, multiple plug-in parts form an integral plug structure through a rigid integrated frame or substrate, and are synchronously docked with the multi-channel interface of the socket. When any of the plug-in parts is damaged due to vibration, overload or long-term use (such as deformation of contacts, wear of plating, failure of insulation layer, etc.), the rigid connection characteristics of the existing design make it impossible to independently disassemble and replace a single faulty plug-in part. The entire combined plug must be removed from the socket, and even the related cables or modules must be removed, which greatly reduces maintenance efficiency.

[0004] Therefore, in order to solve the above technical problems, the present application proposes a vibration-resistant quick-release radio frequency connector and a method of using the same. Summary of the Invention

[0005] In view of the shortcomings of the prior art, the present invention aims to provide a vibration-resistant quick-release radio frequency connector and a method of using the same.

[0006] To achieve the above objectives, the present invention provides the following technical solutions: a vibration-resistant quick-release radio frequency connector, comprising a combined plug and a socket, the combined plug having multiple plug-in portions and connecting wires, and a connecting portion connecting the plug-in portions to the connecting wires, the socket being provided with multiple jacks matching the plug-in portions, the plug-in portions and the connecting portion being detachably connected, a connector being provided at the end of the plug-in portion, and an interface being provided on the connecting portion to match the connector, wherein when the connector is inserted into the interface, an electrical connection is achieved between the plug-in portion and the connecting portion, and the plug-in portion and the connecting portion are connected via a magnetic attraction component; Elastic components are provided on the upper and lower sides of the socket. When the plug-in part is inserted into the socket, the combined plug is squeezed by the upper and lower elastic components to prevent the connection between the combined plug and the socket from loosening due to vibration.

[0007] Preferably, the connecting part is provided with a plurality of circular grooves for inserting the tail of the plug-in part, the interface is arranged on the inner surface of the circular groove, the magnetic attraction component includes an annular magnet A located on the inner surface of the circular groove and arranged around the interface, and an annular magnet B is arranged around the connector on the back of the plug-in part.

[0008] Preferably, connecting plates are provided at both upper and lower ends of the connecting portion, and square blocks are fixedly connected to the surfaces of the connecting plates. Square grooves for inserting square blocks are provided on the surface of the socket at the upper and lower sides of the jack, and connecting grooves are provided on the square blocks. Connecting blocks are installed at the elastic and retractable ends of the elastic component, so that the upper and lower connecting blocks are pushed toward the middle part by the elastic component and inserted into the connecting grooves.

[0009] Preferably, cavities are provided on the upper and lower sides of the socket for the installation of the elastic component, the front plate of the cavity is detachably connected by screws to open the cavity, the elastic component includes a telescopic rod connected to the inner surface of the cavity, the telescopic part of the telescopic rod is fixedly connected to the lifting plate, and a spring is installed between the lifting plate and the inner surface of the cavity, the connecting block is fixed on the lifting plate, a square through slot is provided on the front plate, the front end of the lifting plate is fixedly connected to a connecting rod that passes through the square through slot and can move up and down along the square through slot, and the head of the connecting rod is fixedly connected to the handle A.

[0010] Preferably, the spring is detachably connected in the cavity.

[0011] Preferably, a transverse plate is fixedly connected to the inner surface of the cavity, and insertion blocks are fixedly connected to the upper and lower sides of the spring. Both the transverse plate and the lifting plate are provided with convex through grooves for the insertion blocks to be inserted.

[0012] Preferably, the connecting plate and the connecting part are detachably connected, the back of the connecting plate is fixedly connected to a mounting plate, and the surface of the mounting plate is provided with a plurality of through holes arranged in a horizontal array, the upper and lower sides of the connecting part are fixedly connected with a plurality of screws capable of passing through the through holes, and a nut is threadedly connected to the outer side wall of the screw.

[0013] Preferably, a frame-shaped groove is provided on the surface of the socket around the jack for inserting a dust cover to cover the jack, and a handle B is fixedly connected to the surface of the dust cover.

[0014] Preferably, the upper and lower sides of the dust cover are fixedly connected with a fixing plate that can be inserted into the square groove, the front end of the fixing plate is provided with a bevel A, and the connecting block is provided with a bevel B corresponding to the bevel A.

[0015] The method of using the above-mentioned anti-vibration quick-release RF connector includes the following steps: Step 1: Hold handle B of the dust cover and pull it out firmly to release the fixing plate from the square slot, exposing the socket on the outlet. Step 2: Manually pull the upper and lower handles A, which will drive the two lifting plates to move upward and downward through the connecting rod, overcoming the spring force.

Step 3: Align the plug-in part of the modular plug with the socket of the outlet, and align the square blocks at the upper and lower ends of the connection part with the square grooves of the outlet. Push the modular plug until the upper plug-in part is fully inserted into the socket and the square blocks are fully inserted into the square grooves. At this time, the connection grooves of the square blocks are aligned with the connection blocks. Step 4: Release handle A, the spring resets and pushes the lifting plate to move, driving the connecting block to insert into the connecting groove of the square block. The spring force on the upper and lower sides forms a bidirectional elastic clamping of the modular plug, completing the stable connection between the modular plug and the socket; Step 5: When a single connector is damaged, apply axial pulling force to the connector to be replaced to separate the annular magnet B from the annular magnet A, pull out the faulty connector from the circular groove of the connector, and simultaneously disconnect the electrical connection between the connector and the interface. Align the connector of the new connector with the interface and insert it into the circular groove. Use the adsorption force of the magnetic component to form a reliable electrical connection, thereby completing the rapid replacement of a single connector without affecting the normal operation of other channels.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. Compared with traditional screw fixing, the elastic component of the present invention improves installation efficiency while reducing displacement caused by stress impact on the modular plug caused by vibration through elastic buffering and elastic clamping. Moreover, when a plug part is damaged, only the faulty plug part needs to be removed by overcoming the magnetic attraction force, while the remaining plug parts remain normally connected to the socket through the connecting part. This avoids the disadvantage of traditional rigid integrated structures that require entire disassembly, significantly improves the convenience and reliability of RF connector maintenance, and solves the problems mentioned in the background art. 2. The spring of the present invention is a consumable part and can be replaced individually, which greatly shortens maintenance time and reduces repair costs. At the same time, springs with different elastic parameters can be replaced according to the actual vibration environment, enhancing the adaptability of the RF connector to complex working conditions such as vehicle and airborne installations. 3.

In this way, if the square block is deformed due to improper operation, it can be removed and replaced in time to avoid affecting the normal connection between the combined plug and the socket; 4. When the socket is vacant, the dustproof cover can be used to protect the socket hole thereon from dust, and the dustproof cover can cooperate with the elastic component and the connecting block to be firmly fixed on the surface of the socket.

DETAILED DESCRIPTION

[0019] Example 1 like Figure 1 、 Figure 2 、 Figure 5 as well as Figure 7-Figure 9 As shown, the present invention provides a vibration-resistant quick-release radio frequency connector, including a combined plug 1 and a socket 2. The combined plug 1 has multiple plug-in parts 101 and connecting wires 102, as well as a connecting part 103 connecting the plug-in parts 101 and the connecting wires 102. The socket 2 is provided with multiple jacks 201 matching the plug-in parts 101. The plug-in parts 101 and the connecting part 103 are detachably connected. A connector 1011 is provided at the end of the plug-in part 101, and an interface 1031 equipped with the connector 1011 is provided on the connecting part 103. When the connector 1011 is inserted into the interface 1031, an electrical connection is achieved between the plug-in part 101 and the connecting part 103. The plug-in part 101 and the connecting part 103 are connected via a magnetic attraction component 3. Elastic components 4 are provided on both the upper and lower sides of the socket 2. When the plug-in portion 101 is inserted into the socket 201, the upper and lower elastic components 4 squeeze the combined plug 1 to prevent the connection between the combined plug 1 and the socket 2 from loosening due to vibration.

[0020] The multiple plug-in parts 101 of the modular plug 1 of the present invention are connected to the connecting part 103 via a detachable magnetic component 3. The magnetic component 3 provides an adsorption force, so that the connector 1011 of the plug-in part 101 is firmly inserted into the interface 1031 of the connecting part 103 and forms electrical conduction. At the same time, a single plug-in part 101 can be independently disassembled and replaced without affecting other channels. When the combined plug 1 is inserted as a whole into the socket 2 (the plug-in portion 101 on the combined plug 1 is inserted into the socket 2), the elastic components 4 on the upper and lower sides inside the socket 2 simultaneously squeeze the combined plug 1, and the clamping force generated by elastic deformation avoids displacement caused by vibration, ensuring stable contact of the multi-channel connection interface; compared with traditional screw fixing, the elastic component 4 improves installation efficiency (facilitates quick disassembly between the plug 2 and the combined plug 1), and reduces the displacement caused by the stress impact of vibration on the combined plug 1 through elastic buffering and elastic clamping. Moreover, when a certain plug-in portion 101 is damaged, it is only necessary to overcome the magnetic attraction force to remove the faulty plug-in portion 101 separately, while the remaining plug-in portions 101 still maintain normal connection with the socket 2 through the connecting portion 103 (convenient quick disassembly of a single plug-in portion 101), avoiding the disadvantage of the traditional rigid integrated structure that requires overall disassembly, and significantly improving the convenience and reliability of RF connector maintenance.

[0021] Example 2 like Figure 1-Figure 5 as well as Figure 7-Figure 9 As shown, this embodiment provides the specific structure of the magnetic component 3 and the elastic component 4 in Example 1: The connecting portion 103 is provided with a plurality of circular grooves 1032 for inserting the tail of the plug-in portion 101, and the interface 1031 is provided on the inner surface of the circular groove 1032. The magnetic component 3 includes a ring magnet A301 located on the inner surface of the circular groove 1032 and surrounding the interface 1031. The back of the plug-in portion 101 is provided with a ring magnet B302 surrounding the connector 1011. The upper and lower ends of the connecting portion 103 are provided with connecting plates 5, and the surfaces of the connecting plates 5 are fixedly connected with square blocks 6. The surface of the socket 2 is provided with square grooves 7 for inserting the square blocks 6 on the upper and lower sides of the jack 201. The square blocks 6 are provided with connecting grooves 8. The elastic and telescopic ends of the elastic component 4 are installed with connecting blocks 9 to push the upper and lower connecting blocks 9 toward each other through the elastic component 4. The middle part moves and is inserted into the connecting groove 8. Cavities 202 are provided on the upper and lower sides of the socket 2 for the installation of the elastic component 4. The front plate 203 of the cavity 202 is detachably connected by screws to open the cavity 202. The elastic component 4 includes a telescopic rod 401 connected to the inner surface of the cavity 202. The telescopic part of the telescopic rod 401 is fixedly connected to the lifting plate 402, and a spring 403 is installed between the lifting plate 402 and the inner surface of the cavity 202. The connecting block 9 is fixed on the lifting plate 402, and a square through slot 2031 is provided on the front plate 203. The front end of the lifting plate 402 is fixedly connected to a connecting rod 405 that passes through the square through slot 2031 and can move up and down along the square through slot 2031. The head of the connecting rod 405 is fixedly connected to the handle A404.

[0022] When the plug part 101 is inserted into the circular groove 1032 of the connecting part 103 (and the upper plug 1011 is inserted into the interface 1031 of the connecting part 103), the annular magnet B302 on the back of the plug part 101 and the annular magnet A301 in the circular groove 1032 of the connecting part 103 are tightly fitted together by the magnetic attraction of different poles. The adsorption force ensures a secure connection (electrical connection) between the connector 1011 and the interface 1031, and allows a single plug part 101 to be independently disassembled (axially pulled out) by overcoming the magnetic force, thus realizing the rapid replacement of a faulty unit without affecting other channels. When connecting the modular plug 1 to the socket 2, the upper and lower handles A404 are manually pulled upward and downward. Handles A404 move along the square slot 2031 via the connecting rod 405, thereby driving the two lifting plates 402 to move upward and downward, overcoming the elastic force of the spring 403. The telescopic rod 401 then extends and retracts accordingly (the telescopic rod 401 is used to maintain the vertical linear movement of the lifting plates 402, preventing them from shifting in position and preventing the connecting block 9 on the lifting plates 402 from being inserted into the connecting slot 8). At this point, the connecting block 9 fixed to the lifting plates 402 moves synchronously, completely clearing the square slot 7 area on the surface of the socket 2, leaving ample space for the square block 6 on the connecting portion 103 to be inserted. Then align the plug portion 101 of the modular plug 1 with the socket 201 of the outlet 2, and align the square blocks 6 on the upper and lower sides of the connecting portion 103 with the square grooves 7 of the outlet 2, and then insert. After the plug portion 101 is inserted into the socket 201, the square blocks 6 are also inserted into the square grooves 7. At this time, the connecting grooves 8 on the square blocks 6 are opposite to the connecting blocks 9; Next, release the handle A404, and the spring 403 will reset due to the removal of the external force, pushing the lifting plate 402 to move, driving the connecting block 9 to move toward the connecting slot 8 of the square block 6. When the connecting block 9 is fully inserted into the connecting slot 8, the clamping of the elastic components 4 on the upper and lower sides is evenly transmitted to the connecting part 103 through the matching surfaces of the connecting block 9 and the connecting slot 8, forming a two-way elastic clamping of the combined plug 1. The elastic deformation ability of the spring 403 can dynamically absorb the impact force generated by vibration. In addition, the elastic clamping can effectively prevent the plug-in part 101 from being displaced due to vibration, resulting in the interruption of the connection between the combined plug 1 and the socket 2. At the same time, the concave-convex matching of the connecting block 9 and the connecting slot 8 forms a mechanical interlock, which can effectively suppress the movement of the combined plug 1 in a vibration environment. Combined with the dynamic buffering effect of the spring 403, the vibration energy is offset by the dual mechanism of "rigid limit + elastic buffering", further reducing the risk of displacement of the plug-in part 101.

[0023] When releasing the connection between the combination plug 1 and the socket 2, pull the upper and lower handles A404 upward and downward again, unplug the connecting block 9 from the connecting groove 8, and then pull the square block 6 out of the square groove 7 to release the connection between the combination plug 1 and the socket 2. This makes connection and disconnection very convenient (the combination plug 1 and the socket 2 can be quickly disassembled), which can effectively improve the installation and disassembly efficiency compared to the traditional method of disassembling screws.

[0024] Example 3 like Figure 1-Figure 3 、 Figure 5 as well as Figure 6 As shown, in this embodiment, the spring 403 in Example 2 is detachably connected to the cavity 202, so that the spring 403, as a wearing part, can be replaced separately, which greatly shortens the maintenance time and reduces the repair cost; at the same time, the spring 403 with different elastic parameters can be replaced according to the actual vibration environment (such as adjusting the hardness), thereby enhancing the adaptability of the RF connector to complex working conditions such as vehicle-mounted and airborne. The following is the specific detachable structure: the inner surface of the cavity 202 is fixedly connected with a horizontal plate 10, and the upper and lower sides of the spring 403 are fixedly connected with insertion blocks 11, and the horizontal plate 10 and the lifting plate 402 are both provided with convex through grooves 12 for the insertion blocks 11 to be inserted.

[0025] That is, by removing the screws, the front plate 203 is removed, thereby opening the cavity 202 on the socket 2. After opening, the insertion blocks 11 on the upper and lower sides of the spring 403 are inserted into the convex through grooves 12 on the cross plate 10 and the lifting plate 402 from the front end. Then the front plate 203 is installed. The front and rear ends of the insertion block 11 are restricted by the inner surface of the front plate 203 and the cavity 202 to prevent it from being separated from the convex through groove 12, and the installation of the spring 403 is completed. Conversely, the front plate 203 is removed, and the insertion block 11 is pulled out of the convex groove to achieve the removal of the spring 403.

[0026] This embodiment also provides a detachable connection between the connecting plate 5 and the connecting portion 103 in Example 2. In this way, if the square block 6 is deformed due to improper operation, it can be removed and replaced in time to avoid affecting the normal connection between the combined plug 1 and the socket 2. The following is the specific structure of the detachable connection: the back of the connecting plate 5 is fixedly connected to the mounting plate 19, and the surface of the mounting plate 19 has a plurality of through holes 13 arranged in a horizontal array. The upper and lower sides of the connecting portion 103 are fixedly connected to a plurality of screws 14 that can pass through the through holes 13, and the outer wall of the screw 14 is threadedly connected to a nut 15.

[0027] That is, pass the through hole 13 on the mounting plate 19 through the screw 14 on the connecting part 103. After the insertion is completed, install the nut 15 on the screw 14. The nut 15 moves downward along the screw 14 and slowly presses against the top of the mounting plate 19 to complete the connection between the connecting plate 5 and the square block 6 and the connecting part 103. Conversely, remove the nut 15 and pull the mounting plate 19 off the screw 14 to achieve the disassembly between the connecting plate 5 and the square block 6 and the connecting part 103.

[0028] In addition, this embodiment further provides a frame-shaped groove 204 on the surface of the socket 2 around the socket 201 for the insertion of the dust cover 16, thereby covering the socket 201. When the socket 2 is vacant, the socket 201 thereon is protected from dust. A handle B17 is fixedly connected to the surface of the dust cover 16 to facilitate the insertion and removal of the dust cover 16.

[0029] Furthermore, the upper and lower sides of the dust cover 16 are fixedly connected with a fixing plate 18 that can be inserted into the square groove 7. The front end of the fixing plate 18 is provided with a bevel A1801, and the connecting block 9 is provided with a bevel B901 corresponding to the bevel A1801. That is, when the dust cover 16 is inserted into the frame-shaped groove 204, the fixing plate 18 is also inserted into the square groove 7, and the bevel A1801 at its front end contacts the bevel B901 on the connecting block 9, thereby pushing the two connecting blocks 9 to move slightly upward and downward, so that they can be smoothly inserted into the square groove 7 (the handle A404 cannot be pulled). After insertion, the connecting block 9 is pressed by the force of the spring 403, thereby ensuring the firmness of its installation (the dust cover 16 can be removed by force to overcome the pressure of the connecting block 9 on the fixing plate 18).

[0030] The present invention also provides a method for using the above-mentioned anti-vibration quick-release RF connector: Step 1: Grip the handle B17 of the dust cover 16 and pull out the dust cover 16 with force, so that the fixing plate 18 is separated from the square groove 7, exposing the socket 201 on the socket 2; Step 2: Manually pull the upper and lower handles A404, and drive the two lifting plates 402 to move upward and downward through the connecting rod 405 to overcome the elastic force of the spring 403, so that the connecting block 9 is completely out of the square groove 7 area, leaving space for the square block 6 on the connecting part 103 to be inserted; Step 3: Align the plug portion 101 of the modular plug 1 with the socket 201 of the outlet 2. At the same time, align the square blocks 6 at the upper and lower ends of the connecting portion 103 with the square slots 7 of the outlet 2. Push the modular plug 1 until the plug portion 101 is fully inserted into the socket 201 and the square blocks 6 are fully inserted into the square slots 7. At this point, the connecting slots 8 of the square blocks 6 are aligned with the connecting blocks 9. Step 4: Release handle A404, spring 403 resets and pushes lift plate 402 to move, driving connecting block 9 to insert into connecting slot 8 of square block 6. The elastic force of springs 403 on both sides forms a bidirectional elastic clamping on modular plug 1, completing the stable connection between modular plug 1 and socket 2. Step 5: When a single plug-in part 101 is damaged, apply axial pulling force to the plug-in part 101 to be replaced to separate the annular magnet B302 from the annular magnet A301, pull out the faulty plug-in part 101 from the circular groove 1032 of the connecting part 103, and simultaneously disconnect the electrical connection between the connector 1011 and the interface 1031. Align the connector 1011 of the new plug-in part 101 with the interface 1031 and insert it into the circular groove 1032. Use the adsorption force of the magnetic component 3 to form a reliable electrical connection, and complete the rapid replacement of a single plug-in part 101 without affecting the normal operation of other channels.

[0031] The vibration-resistant quick-release radio frequency connector and its use method of the present invention have the following advantages: Compared to traditional screw fixing, the elastic component 4 improves installation efficiency while reducing the displacement caused by the stress impact of vibration on the modular plug 1 through elastic buffering and elastic clamping. Moreover, when a certain plug part 101 is damaged, it is only necessary to overcome the magnetic attraction force to remove the faulty plug part 101 separately, while the remaining plug parts 101 remain normally connected to the socket 2 through the connecting part 103. This avoids the disadvantage of the traditional rigid integrated structure that requires overall disassembly, and significantly improves the convenience and reliability of RF connector maintenance. Spring 403, as a consumable part, can be replaced individually, significantly shortening maintenance time and reducing repair costs. Springs 403 with different elastic parameters can also be replaced based on the actual vibration environment, enhancing the RF connector's adaptability to complex operating conditions such as vehicle and airborne installations. The connecting plate 5 and the connecting portion 103 are detachably connected, so that if the square block 6 is deformed due to improper operation, it can be removed and replaced in time to avoid affecting the normal connection between the combined plug 1 and the socket 2; When the socket 2 is vacant, the jack 201 thereon can be protected from dust by the dust cover 16 , and the dust cover 16 can cooperate with the elastic component 4 and the connecting block 9 to be securely fixed to the surface of the socket 2 .
