Description

Technical Field

[0001] The present invention relates to the technical field of radio frequency connectors, and in particular to a radio frequency coaxial connector and an assembling method thereof. Background Art

[0002] An RF connector is a connector used to transmit high-frequency signals. It is usually installed on wires or equipment. As a detachable component of a transmission line system, it transmits RF signals by connecting the conductors. It is designed to maintain the continuity and stability of high-frequency signals during connection and disconnection. There are many types of RF connectors, including RF coaxial connectors, microwave connectors, and fiber optic connectors. Each type has its specific application scenarios and advantages and disadvantages. RF connectors are widely used in communication equipment, wireless LAN equipment, satellite communication equipment, RF test and measurement equipment, medical equipment, and military and aerospace applications.

[0003] Currently, the widely used RF connectors mainly use threads to install and fix the wires. However, this connection method brings many inconveniences in disassembly and reassembly due to its tightness and complexity. Specifically, disassembly and reassembly often require specific tools and take a long time, which not only increases the difficulty and cost of repairing or replacing parts, but also may delay the repair progress in an emergency and affect the timely recovery of the equipment. In addition, threaded connections are prone to loosening when used for a long time or facing harsh environments such as external vibration, corrosion and high temperature. This loosening will not only reduce the stability of the connection, but may also cause a significant decrease in connection performance, thereby adversely affecting the transmission quality of the RF signal. Summary of the invention

[0004] The purpose of the present invention is to provide a radio frequency coaxial connector and an assembly method thereof, so as to solve the problem that the connector generally adopts threads to connect with the wires, which is not only time-consuming and labor-intensive to install and disassemble, but also the threads are easily damaged, resulting in unstable connection and thus affecting the performance of the connector.

When the sliding sleeve is pushed forward, the clamping tongue inside the cylinder will cooperate with the tooth groove to prevent the sliding sleeve from retreating, thereby affecting the installation and fixing effect; The clamping mechanism is installed inside the fixing mechanism and is used to clamp the wire. When the sliding sleeve moves forward, the protruding point is lifted up to drive the rotating plate to rotate. The positioning microneedles installed on the rotating plate will penetrate into the wire skin under pressure to quickly fix the wire inside the sliding sleeve. The insurance mechanism is installed between two fixed mechanisms and is used to connect two conductors so that the current signal can be transmitted smoothly between the two wires.

[0010] Preferably, a group of the rotating plates are all wound with hook springs on their tops, a group of the mounting grooves have inner walls that are intertwined with outer walls of the hook springs, and the outer walls of the plurality of positioning microneedles are in contact with the outer walls of the protective layer.

[0011] Preferably, the safety mechanism includes a connecting sleeve; The outer walls of the two cylinders are in contact with the outer wall of the connecting sleeve, a group of connecting frames are fixedly installed on the inner wall of the connecting sleeve, a positioning sleeve is fixedly installed between the outer walls of a group of connecting frames, a threaded hole is opened on the top of the positioning sleeve, and a positioning bolt is threadedly connected to the inner wall of the threaded hole, and a rubber block is fixedly installed on the bottom of the positioning bolt.

[0012] Preferably, a fuse tube is movably inserted into the inner surface wall of the positioning sleeve, and the outer surface wall of the fuse tube is in contact with the outer surface wall of the rubber block, and the outer surface wall of the fuse tube is in contact with the outer surfaces of the two conductors. Two groups of movable holes 2 are opened on the outer surface wall of the connecting sleeve, and rods are movably inserted into the inner surfaces of the two groups of the movable holes 2. Push plates are fixedly installed between the outer surfaces of the two groups of the rods, and two groups of tension springs 3 are fixedly installed on the inner surface wall of the connecting sleeve.

[0013] Preferably, the outer walls of the two groups of the insertion rods are fixedly installed with clamping racks, and one side of the outer walls of the two groups of clamping racks is fixedly connected to the outer wall of the tension spring three, the inner wall of the connecting sleeve is fixedly installed with four fixing rods two, the outer walls of the four fixing rods two are movably sleeved with gears, and two outer walls of the four gears are fixedly connected to the inner wall of a group of clamping racks, the inner wall of the connecting sleeve is fixedly installed with four groups of guide rails, the inner walls of the four groups of guide rails are movably embedded with sliders two, the outer walls of the four groups of sliders two are fixedly installed with moving racks on one side, and the outer walls of the four gears are fixedly connected to the inner wall of a group of moving racks.

[0014] A method for using a radio frequency coaxial connector comprises the following steps: Step 1: When the connector needs to be fixed on the surface of the wire, the protective layer and the insulating layer of the wire can be peeled off first, and then the sliding sleeve can be put on the surface of the wire. At this time, the user can push the sliding sleeve to slide. When the sliding sleeve moves, it will push the slider to slide synchronously in the sliding groove. At the same time, the slider will also drive the tension spring to stretch. As the sliding sleeve continues to advance, its front end will gradually contact the protruding point at the bottom of the rotating plate and cause the protruding point to move outward. In this process, the protruding point will drive the rotating plate to rotate around the fixed rod 1. Since the rotating plate and the fixed rod 1 form a laborious lever structure, a large displacement will occur on the other side of the rotating plate, allowing multiple positioning microneedles to pass through the through holes on the sliding sleeve, penetrate the wire skin, and lock the wire inside the device; Step 2: As the sleeve is installed further, the two sets of tooth grooves on its outer wall also move accordingly. These tooth grooves cooperate with the tension spring 1 to push the latch tongue to rise and fall continuously. When the sleeve is completely inserted into the cylinder, the tension spring 1 pushes the latch tongue to be firmly embedded in the last tooth groove. The tight engagement between the latch tongue and the tooth groove prevents the sleeve from accidentally retreating. Step 3: After the sleeve is fixed, the moving rack will extend out of the cylinder. The user needs to dock the two connectors. Just press the two push plates inwards to drive the plug rod to stretch the spring three and separate the clamping rack from the gear. Then, the slider two at the bottom of the moving rack can be slid into the guide rail. At this time, the moving racks on the left and right sides are combined in pairs and form a tight meshing connection with a gear respectively. At this time, each gear starts to rotate under the push of the two moving racks, and the three are tightly combined into an inseparable whole. Step 4: When the two cylinders are fitted with the connecting sleeve, the user will release the push plate, and the tension spring 3 will drive the clamping rack to move through the plug rod, so that it moves to the same plane as the gear and meshes with each other, ensuring that no movement can occur between all gears and the moving rack, thus achieving a stable connection state; Step 5: After the connection, the two conductors establish electrical connections with the two ends of the fuse. Once a component in the circuit fails or an abnormal situation occurs, the fuse can respond quickly and blow, thereby cutting off the faulty circuit in time. After the fuse blows, the user can replace the fuse by rotating the positioning bolt in the reverse direction.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. In the present invention, the connector needs to be fixed on the surface of the wire. It only needs to push the sliding sleeve. Through the design of the sliding sleeve and the rotating plate, the positioning microneedle is inserted into the surface of the wire to fix the wire. At this time, the tongue will also be inserted into the tooth groove on the sliding sleeve, thereby avoiding circuit failure caused by loose connection. This structure allows the user to quickly fix the connector on the wire or remove it. Compared with the traditional threaded connection method, it significantly shortens the installation and maintenance time and improves work efficiency. The traditional threaded connection is easily damaged due to long-term use or improper operation, and this design fundamentally avoids this risk and extends the service life of the connector.

[0016] 2. In the present invention, the wire connector realizes fast and stable connection and disassembly between connectors through the precise matching of multiple components, which not only improves the connection efficiency and stability of the connector, but also simplifies the connection and disassembly operation steps and reduces the operation difficulty.

[0017] 3. In the present invention, when a component in the circuit fails or becomes abnormal, causing the current to increase abnormally, the fuse can be quickly blown, cutting off the faulty circuit in time, effectively preventing the faulty current from causing further damage to the entire system, thereby significantly improving the reliability and safety of the entire system.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the implementation regulations described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] Embodiment 1, refer to Figure 1-Figure 8 As shown: The present invention provides a radio frequency coaxial connector, comprising: a fixing mechanism 1, a clamping mechanism 2 and a safety mechanism 3, The fixing mechanism 1 is provided with two, as the main structure for protection and connection, which is sleeved on the surface of the wire to be installed to protect the wire. When the sliding sleeve 102 is pushed forward, the latch 116 inside the cylinder 109 will cooperate with the tooth groove 103 to prevent the sliding sleeve 102 from retreating, thereby affecting the installation and fixing effect; The clamping mechanism 2 is installed inside the fixing mechanism 1 and is used to clamp the wire. When the sliding sleeve 102 moves forward, the protruding point 203 is lifted up to drive the rotating plate 202 to rotate. The positioning micro needles 204 installed on the rotating plate 202 will penetrate into the wire skin under pressure to quickly fix the wire inside the sliding sleeve 102. The insurance mechanism 3 is installed between the two fixing mechanisms 1 and is used to connect the two conductors 108 so that the current signal can be smoothly transmitted between the two wires. When an abnormal current occurs, the insurance tube 307 will quickly blow to avoid the spread of the fault and prevent safety accidents such as equipment damage or fire caused by excessive current. Two fixing mechanisms 1, which include: a protective layer 101, the outer wall of the protective layer 101 is movably sleeved with a sliding sleeve 102, the outer wall of the sliding sleeve 102 is provided with two groups of tooth grooves 103, the outer wall of the sliding sleeve 102 is provided with four through holes 104, the outer wall of the sliding sleeve 102 is fixedly installed with four sliders 105, one side of the outer wall of the four sliders 105 is fixedly installed with a tension spring 106, the inner wall of the protective layer 101 is provided with an insulating layer 107, the inner wall of the insulating layer 107 is provided with a conductor 108, the outer wall of the sliding sleeve 102 is movably sleeved with a cylinder 109, the inner wall of the cylinder 109 is provided with four sliding grooves 110, and the inner walls of the four sliding grooves 110 are all movably embedded with the outer wall of the slider 105, and one side of the inner wall of the four sliding grooves 110 is fixed with the tension spring 106. The outer wall of the spring 106 is fixedly connected, and two movable holes 111 are provided on the outer wall of the cylinder 109. The inner walls of the two movable holes 111 are movably inserted with connecting plates 112. Handles 113 are fixedly installed on one side of the outer walls of the two connecting plates 112. A group of tension springs 114 are fixedly installed on one side of the outer walls of the two handles 113. A mounting plate 115 is fixedly installed on the outer walls of the two groups of tension springs 114. The inner walls of the two movable holes 111 are fixedly inserted with the outer walls of a group of mounting plates 115. A tongue 116 is fixedly installed on one side of the outer walls of the two connecting plates 112. One of the inner walls of the two groups of tooth grooves 103 is movably inserted with the outer wall of the tongue 116. A group of mounting grooves 117 are provided on the inner wall of the cylinder 109. The clamping mechanism 2 includes a fixing rod 201, a group of inner surfaces of the mounting grooves 117 are fixedly connected to the outer surfaces of the fixing rod 201, a group of outer surfaces of the fixing rod 201 are movably sleeved with a rotating plate 202, a group of protrusions 203 are fixedly installed at the bottom of the rotating plate 202, a group of positioning microneedles 204 are fixedly installed on one side of the outer wall of the rotating plate 202, a group of hook springs 205 are wound around the top of the rotating plate 202, a group of inner walls of the mounting grooves 117 are mutually wound with a group of outer walls of the hook springs 205, and the outer surfaces of the multiple positioning microneedles 204 are in contact with the outer surface of the protective layer 101.

[0022] In this embodiment, the user first peels off the protective layer 101 and the insulating layer 107 at the front end of the wire to expose the internal conductor 108, and then inserts the wire into the sliding sleeve 102. When the connector needs to be put on the surface of the wire, it is only necessary to fix the position of the wire and the cylinder 109, and push the sliding sleeve 102 to make it slide between the cylinder 109 and the wire. At this time, the slider 105 on the surface of the sliding sleeve 102 slides synchronously inside the sliding groove 110. The slider 105 and the sliding groove 110 cooperate with each other to effectively prevent the sliding sleeve 102 from rotating when sliding. The slider 105 will also pull the tension spring 106 at this time, and the tension spring 106 makes When the sliding sleeve 102 is not in use, the front end of the sliding sleeve 102 will contact the protruding point 203 at the bottom of the rotating plate 202 and push the protruding point 203 outward. At this time, the protruding point 203 will drive the rotating plate 202 to rotate on the surface of the fixed rod 201. Since the rotating plate 202 and the fixed rod 201 are combined to form a laborious lever, its power arm is smaller than the resistance arm. Therefore, when the force point moves a small distance, the resistance point can also produce corresponding movement, thereby achieving the effect of saving distance. When the protruding point 203 drives one end of the power arm of the rotating plate 202 to rotate and rise a short distance, the rotating plate 202 resistance arm One end of the force arm will move a large distance, thereby passing through the through hole 104 on the sliding sleeve 102, so that multiple positioning microneedles 204 are inserted into the surface of the wire, and the wire is quickly fixed inside the device. When the sliding sleeve 102 is continuously moving forward, the two sets of tooth grooves 103 on its outer wall will move synchronously. When the tooth groove 103 moves forward, the latch tongue 116 that matches its tooth shape will be continuously pushed upward, and the latch tongue 116 will push the handle 113 to rise synchronously and pull the tension spring 106. When the sliding sleeve 102 is completely inserted into the cylinder 109, the latch tongue 116 is then driven by the tension spring 106 to be inserted into the last tooth groove 103. When 103 moves forward, it will continuously push up the latch 116, but the latch 116 can also prevent the tooth groove 103 from retreating, and by fixing the position of the sliding sleeve 102, it ensures that the wire can be firmly fixed. Since there is no need for threaded connection, the installation and maintenance time is significantly shortened, the work efficiency is improved, the risk of thread damage is fundamentally avoided, and the stability and reliability of the connection are ensured. When the connector needs to be removed from the wire, it is only necessary to pull the handle 113 to drive the latch 116 to rise, and the sliding sleeve 102 will be driven back by the reset tension spring 106, and the positioning microneedle 204 will also be separated from the wire, making it convenient for the wire to be pulled out.

[0023] Embodiment 2, according to Figure 2-Figure 4 as well as Figure 6-Figure 8As shown, the safety mechanism 3 includes a connecting sleeve 301, the outer walls of the two cylinders 109 are in contact with the outer wall of the connecting sleeve 301, the outer wall of the connecting sleeve 301 is provided with two groups of movable holes 2 308, the inner walls of the two groups of movable holes 2 308 are movably inserted with plug rods 309, and push plates 310 are fixedly installed between the outer walls of the two groups of plug rods 309, the inner wall of the connecting sleeve 301 is fixedly installed with two groups of tension springs 311, the outer walls of the two groups of plug rods 309 are fixedly installed with clamping racks 312, and one side of the outer walls of the two groups of clamping racks 312 are fixedly connected to the outer wall of the tension spring 3 311, and the inner wall of the connecting sleeve 301 is fixedly installed Four fixed rods 313 are installed, and the outer walls of the four fixed rods 313 are movably sleeved with gears 314, and two outer walls of the four gears 314 are fixedly connected to the inner wall of a group of clamping racks 312, and the inner wall of the connecting sleeve 301 is fixedly installed with four groups of guide rails 315, and the inner walls of the four groups of guide rails 315 are movably embedded with sliders 2 316, and one side of the outer wall of the four groups of sliders 2 316 is fixedly installed with a moving rack 317, and the outer walls of the four gears 314 are fixedly connected to the inner wall of a group of moving racks 317, and the outer wall of one of the four groups of moving racks 317 is fixedly connected to one side of the outer wall of the sliding sleeve 102.

[0024] In this embodiment, after the wire is fixed inside the sliding sleeve 102, the sliding sleeve 102 will also push the movable rack 317 out of the cylinder 109. If the two connectors need to be connected, it is only necessary to take out the connecting sleeve 301 and squeeze the two push plates 310 inward first. At this time, the push plates 310 will drive the insertion rod 309 to move inside the movable hole 2 308. The insertion rod 309 will pull the tension spring 311 at this time, and separate the clamping rack 312 from the gear 314, so that the multiple gears 314 can rotate freely on the surface of the fixed rod 2 313, and then insert the movable racks 317 on the two cylinders 109 into the connecting sleeve 301. At this time, the slider 2 316 at the bottom of the movable rack 317 is inserted into the guide rail 315. The guide rail 315 can prevent the slider 2 316 and the movable rack 317 from offset in moving direction. The movable racks 317 inside the cylinders 109 correspond to each other in pairs and are respectively meshed with a gear 314. Each gear 314 will rotate under the push of the two movable racks 317, and the three constitute a whole. When the two cylinders 109 are tightly fitted with the connecting sleeve 301 so that the circuit is connected, the user can loosen the push plate 310. At this time, the push plate 310 begins to be pulled outward by the tension spring 311, and drives the clamping rack 312 to move through the insertion rod 309. At this time, the clamping rack 312 is meshed with the gear 314. By clamping the two gears 314, it is ensured that all gears 314 and the movable rack 317 cannot continue to move. When the connector needs to be disassembled, it is only necessary to pull the push plate 310 again to cancel the fixation of the two gears 314, so that the two cylinders 109 and the connecting sleeve 301 can be separated from each other.

[0025] Embodiment 3, according to Figure 2-Figure 4 , Figure 6 and Figure 8 As shown, the safety mechanism 3 includes a connecting sleeve 301, the outer walls of the two cylinders 109 are in contact with the outer wall of the connecting sleeve 301, a group of connecting frames 302 are fixedly installed on the inner wall of the connecting sleeve 301, and a positioning sleeve 303 is fixedly installed between the outer walls of a group of connecting frames 302. A threaded hole 304 is opened on the top of the positioning sleeve 303, and a positioning bolt 305 is threadedly connected to the inner wall of the threaded hole 304. A rubber block 306 is fixedly installed at the bottom of the positioning bolt 305. A fuse tube 307 is movably inserted into the inner wall of the positioning sleeve 303, and the outer wall of the fuse tube 307 is in contact with the outer wall of the rubber block 306, and the outer wall of the fuse tube 307 is in contact with the outer walls of the two conductors 108.

[0026] In this embodiment, when the two connectors are connected, the conductors 108 are not in direct contact with each other, but are in contact with the two ends of the fuse 307 respectively. When a component in the circuit fails or is abnormal, the current may suddenly increase, thereby causing damage to the entire system. After adding the fuse 307, when an abnormal current occurs, the fuse 307 will quickly blow, thereby avoiding the spread of the fault and improving the reliability of the entire system. After the fuse 307 is used, the positioning bolt 305 can be rotated in the reverse direction to separate the rubber block 306 from the fuse 307, and then the fuse 307 can be pulled out and replaced, and the device can be used again, avoiding the cost of overall replacement.

[0027] The working principle of the entire mechanism is as follows: when using the wire connector, the user first needs to peel off the protective layer 101 and the insulating layer 107 at the front end of the wire to expose the internal conductor 108, and then insert the wire into the inside of the sleeve 102. In order to fix the connector on the surface of the wire, the user only needs to stabilize the position of the wire and the cylinder 109, and push the sleeve 102 to make it slide smoothly between the cylinder 109 and the wire. The slider 105 equipped on the surface of the sleeve 102 will slide synchronously inside the slide groove 110 to prevent the sleeve 102 from rotating during the sliding process. At the same time, the slider 105 will also pull the tension spring 106. As the sleeve 102 continues to move forward, its front end will contact the protruding point 203 at the bottom of the rotating plate 202 and push. The protruding point 203 moves outward. At this time, the protruding point 203 will drive the rotating plate 202 to rotate around the fixed rod 201. Since the rotating plate 202 and the fixed rod 201 form a laborious lever, when the protruding point 203 drives the power arm end of the rotating plate 202 to rise a short distance, its resistance arm end will move a larger distance, thereby passing through the through hole 104 of the sliding sleeve 102, so that the multiple positioning microneedles 204 can easily penetrate the wire epidermis, quickly fix the wire inside the device, and realize fast and reliable fixation of the wire. As the sliding sleeve 102 continues to penetrate, the two sets of tooth grooves 103 carefully designed on its outer wall move accordingly. These tooth grooves 103 guide the tongues 116 that fit their shapes to gradually rise. While the tongues 116 rise, The handle 113 is pushed up together, and in the process, the tension spring 106 is pulled. When the sliding sleeve 102 completely enters the cylinder 109, the elastic force of the tension spring 106 comes into play, pushing the latch 116 to be firmly embedded in the last tooth groove 103, which not only ensures the stability of the sliding sleeve 102 in the process of advancing, but also effectively prevents the sliding sleeve 102 from retreating through the close cooperation between the latch 116 and the tooth groove 103, thereby realizing the firm fixation of the wire. When the wire is firmly fixed in the sliding sleeve 102, the sliding sleeve 102 will push the moving rack 317 out of the cylinder 109. If the two connectors need to be docked, the user only needs to take out the connecting sleeve 301 and squeeze the two push plates 310 inwards. The push plate 310 drives the insertion rod 309 to slide in the movable hole 2 308, thereby stretching the spring 311 and temporarily separating the clamping rack 312 from the gear 314, so that the multiple gears 314 can rotate freely on the fixed rod 2 313. Next, the user needs to align the moving racks 317 on the two cylinders 109 and insert them into the connecting sleeve 301. During this process, the slider 2 316 at the bottom of the moving rack 317 will slide smoothly into the guide rail 315. Once the moving racks 317 of the two cylinders 109 correspond to each other and are inserted into the connecting sleeve 301, they will respectively form a meshing connection with a gear 314. At this time, each gear 314 starts to rotate under the push of the two moving racks 317, and the three are tightly combined into a whole.When the two cylinders 109 are tightly fitted with the connecting sleeve 301, the user can loosen the push plate 310. Under the elastic force of the tension spring 311, the push plate 310 will move outward and drive the clamping rack 312 to move to a position meshing with the gear 314 through the insertion rod 309, thereby firmly locking the two gears 314 and ensuring that all gears 314 and the moving rack 317 cannot move anymore. During the docking process of the two connectors, the conductors 108 do not directly contact each other, but establish electrical connections with the two ends of the fuse 307 respectively, thereby enhancing the safety and reliability of the circuit. Once a component in the circuit fails or is abnormal, the current will increase abnormally. When the abnormal current appears, the fuse 307 can respond quickly and blow, thereby cutting off the fault circuit in time, effectively preventing the expansion of the fault range, and ensuring the stable operation of the entire system. After the fuse 307 blows, the user can easily replace the fuse 307 by rotating the positioning bolt 305 in the reverse direction. During this process, the rubber block 306 will separate from the fuse 307, so that the user can easily pull out the blown fuse 307 and insert a new fuse 307 for replacement.

[0028] The present invention also provides a method for using a radio frequency coaxial connector, comprising the following steps: Step 1: When the connector needs to be fixed on the surface of the wire, the protective layer 101 and the insulating layer 107 of the wire can be peeled off first, and then the sliding sleeve 102 can be put on the surface of the wire. At this time, the user can push the sliding sleeve 102 to slide. When the sliding sleeve 102 moves, it will push the slider to slide synchronously in the sliding groove 110. At the same time, the slider 105 will also drive the tension spring 106 to stretch. As the sliding sleeve 102 is continuously pushed forward, its front end will gradually contact the protruding point 203 at the bottom of the rotating plate 202, and cause the protruding point 203 to move outward. In this process, the protruding point 203 will drive the rotating plate 202 to rotate around the fixed rod 1 201. Since the rotating plate 202 and the fixed rod 1 201 form a laborious lever structure, the other side of the rotating plate 202 will have a large displacement, so that multiple positioning microneedles 204 can pass through the through holes 104 on the sliding sleeve 102, penetrate the wire skin, and lock the wire inside the device; Step 2: As the sleeve 102 is installed further, the two sets of tooth grooves 103 on its outer wall also move accordingly. These tooth grooves 103 cooperate with the tension spring 106 to push the latch 116 to rise and fall continuously. When the sleeve 102 completely enters the cylinder 109, the tension spring 106 pushes the latch 116 to be firmly embedded in the last tooth groove 103. The tight engagement between the latch 116 and the tooth groove 103 prevents the sleeve 102 from accidentally retreating. Step 3: After the sleeve 102 is fixed, the moving rack 317 will extend out of the cylinder 109. The user needs to dock the two connectors. He only needs to gently press the two push plates 310 inward to drive the insertion rod 309 to stretch the spring 311 and separate the clamping rack 312 from the gear 314. Then, the slider 2 316 at the bottom of the moving rack 317 can be slid into the guide rail 315. At this time, the moving racks 317 on the left and right sides are combined in pairs and form a tight meshing connection with a gear 314 respectively. At this time, each gear 314 starts to rotate under the push of the two moving racks 317, and the three are tightly combined into an inseparable whole. Step 4: When the two cylinders 109 are fitted with the connecting sleeve 301, the user will release the push plate 310, and the tension spring 311 will drive the clamping rack 312 to move through the insertion rod 309, so that it moves to the same plane as the gear 314 and meshes with each other, ensuring that no movement can occur between all gears 314 and the moving rack 317, thus achieving a stable connection state; Step 5: After the connection, the two conductors 108 respectively establish electrical connections with the two ends of the fuse 307. Once a component in the circuit fails or an abnormal situation occurs, the fuse 307 can respond quickly and blow, thereby cutting off the faulty circuit in time. After the fuse 307 blows, the user can replace the fuse 307 by rotating the positioning bolt 305 in the reverse direction.

10. A method for using a radio frequency coaxial connector, using the radio frequency coaxial connector according to claim 9, comprising the following steps: S1: When the connector needs to be fixed on the surface of the wire, the protective layer (101) and the insulating layer (107) of the wire can be peeled off first, and then the sliding sleeve (102) can be put on the surface of the wire. At this time, the user can push the sliding sleeve (102) to slide. When the sliding sleeve (102) moves, it will push the slider to slide in the sliding groove (110) synchronously. At the same time, the slider (105) will also drive the tension spring (106) to stretch. As the sliding sleeve (102) is continuously pushed forward, its front end will gradually align with the protrusion at the bottom of the rotating plate (202). The protruding point (203) contacts the protruding point (203) and causes the protruding point (203) to move outward. During this process, the protruding point (203) drives the rotating plate (202) to rotate around the fixed rod (201). Since the rotating plate (202) and the fixed rod (201) form a forceful lever structure, a large displacement occurs on the other side of the rotating plate (202), thereby allowing the plurality of positioning microneedles (204) to pass through the through holes (104) on the sliding sleeve (102), penetrate the wire skin, and lock the wire inside the device; S2: As the sliding sleeve (102) is installed further, the two sets of tooth grooves (103) on its outer wall also move accordingly. These tooth grooves (103) cooperate with the tension spring 1 (106) to push the latch tongue (116) to rise and fall continuously. When the sliding sleeve (102) completely enters the cylinder (109), the tension spring 1 (106) pushes the latch tongue (116) to be firmly embedded in the last tooth groove (103). The tight engagement between the latch tongue (116) and the tooth groove (103) prevents the sliding sleeve (102) from accidentally retreating. S3: After the sliding sleeve (102) is fixed, the movable rack (317) will be extended out of the cylinder (109). When the user needs to dock the two connectors, he only needs to gently press the two push plates (310) inward, so that the push plates (310) drive the insertion rod (309) to stretch the spring three (311) and separate the clamping rack (312) from the gear (314). Then, the slider two (316) at the bottom of the movable rack (317) can be slid into the guide rail (315). At this time, the movable racks (317) on the left and right sides are combined in pairs and form a tight meshing connection with a gear (314) respectively. At this time, each gear (314) starts to rotate under the push of the two movable racks (317), and the three are tightly combined into an inseparable whole. S4: When the two cylinders (109) are fitted with the connecting sleeve (301), the user releases the push plate (310), and the tension spring (311) drives the clamping rack (312) to move through the insertion rod (309), so that the clamping rack (312) and the gear (314) move to the same plane and mesh with each other, ensuring that no movement can occur between all the gears (314) and the moving rack (317), thereby achieving a stable connection state; S5: After the connection, the two conductors (108) respectively establish electrical connections with the two ends of the fuse (307). Once a component in the circuit fails or an abnormal situation occurs, the fuse (307) can respond quickly and blow, thereby cutting off the faulty circuit in time. After the fuse (307) blows, the user can replace the fuse (307) by rotating the positioning bolt (305) in the opposite direction.
