Technical Field

[0001] This application relates to the field of radio frequency connector technology, and particularly to a quick-disconnect connection structure for a radio frequency power supply connection port. Background Art

[0002] A radio frequency power connector is an electronic component used for high-frequency signal transmission, mainly used to connect different radio frequency devices, and is usually installed on a cable or device as a separable component for electrical connection of a transmission line system.

[0003] Currently, in existing radio frequency power connectors, after multiple disassembly and assembly or after disassembly and long-term non-connection, dust and the like may exist between the inner conductor and the outer conductor, resulting in problems such as a decrease in electrical performance, an increase in contact resistance, and an increase in insertion loss. And it is possible that a relatively large operating force is required when connecting or disconnecting the connection structure, or the operation process is not smooth enough, resulting in deformation of the inner conductor or outer conductor and loosening of the inner conductor welding. Summary of the Invention

[0004] In order to improve the problems of increased resistance and loss caused by dust entry and deformation of the inner and outer conductors due to the need for strong disassembly and assembly, this application provides a quick-disconnect connection structure for a radio frequency power supply connection port.

[0005] A quick-disconnect connection structure for a radio frequency power supply connection port provided by this application adopts the following technical solutions: A quick-disconnect connection structure for a radio frequency power supply connection port includes a female connector and a male connector that are inserted and fixed to each other. A female terminal for inserting into a male terminal fixed inside the male connector to achieve signal transmission is fixedly installed inside the female connector. A first sealing mechanism for scraping and cleaning foreign objects and dust from the outer ring surface of the female terminal is provided at the mating interface of the female connector. A second sealing mechanism for scraping and cleaning foreign objects and dust from the outer ring surface of the male terminal is provided at the mating interface of the male connector. The first sealing mechanism and the second sealing mechanism have the same structure and can both seal the mating interfaces of the female connector and the male connector during disassembly. A transverse moving abutting mechanism for abutting and limiting the female connector and the male connector to achieve fixation is provided inside the male connector. The transverse moving abutting mechanism is used to guide the insertion of the female terminal and the male terminal to prevent distortion and deformation.

[0006] By adopting the above technical solutions, the first sealing mechanism and the second sealing mechanism can seal the mating interfaces of the female connector and the male connector during disassembly, prevent dust and debris from entering, and extend the service life of the connection structure. The transverse moving abutting mechanism not only realizes the quick fixation of the female connector and the male connector, but also can accurately guide the insertion of the female terminal and the male terminal, avoid distortion and deformation during the insertion process, and ensure the accuracy of signal transmission.

[0007] Preferably, an outer ring groove and an inner ring insert for mutual plugging and sealing are respectively provided on one side of the female connector and the male connector, and a plurality of symmetrically arranged L-shaped blocks are fixedly provided on one side of the outer ring groove.

[0008] By adopting the above technical solution, the plugging and sealing design of the outer ring groove and the inner ring insert further enhances the sealing performance between the female connector and the male connector, effectively preventing external dust and moisture from entering the inside of the connection structure, while the L-shaped blocks can play a role in limiting and fixing the female connector and the male connector.

[0009] Preferably, the transverse movement and abutting mechanism includes a sliding ring A and a sliding ring B slidably arranged outside the male terminal. A plurality of link A and link B which are symmetrically arranged on the sliding ring A and the sliding ring B and are rotatably connected to each other to realize lifting are provided. One side of a plurality of the link A and the link B is abutted with an L-shaped limiting block for abutting and limiting the L-shaped block.

[0010] By adopting the above technical solution, the sliding design of the sliding ring A and the sliding ring B enables the transverse movement and abutting mechanism to flexibly adapt to the docking process of the female connector and the male connector. The rotational connection and lifting functions of the link A and the link B realize the precise abutting and limiting of the L-shaped block, ensuring that the female connector and the male connector can be accurately in place and firmly fixed when docked.

[0011] Preferably, the L-shaped limiting block is rotatably arranged inside a limiting groove opened on the inner ring surface of the male connector. An L-shaped sliding groove for slidably plugging with the L-shaped block is provided on one side of the limiting groove, and an anti-detachment block for clamping and limiting the L-shaped block is fixedly provided on one side of the L-shaped sliding groove.

[0012] By adopting the above technical solution, the sliding plugging design of the L-shaped sliding groove and the L-shaped block further enhances the connection stability between the female connector and the male connector. The setting of the anti-detachment block effectively prevents the L-shaped block from coming out under the action of vibration or external force, ensuring the long-term reliability of the connection structure.

[0013] Preferably, a vertical sliding groove penetrating the male connector is provided on one side of the limiting groove. A T-shaped pressing block abutted with the link A is slidably arranged in the vertical sliding groove, and a plurality of symmetrically arranged triangular limiting blocks for abutting and limiting with the inner ring surface of the male connector are fixedly provided on one side of the T-shaped pressing block.

[0014] By adopting the above technical solution, the sliding design of the vertical sliding groove and the T-shaped pressing block enables the operator to conveniently drive the transverse movement and abutting mechanism to act by pressing the T-shaped pressing block, realizing the quick disassembly and assembly of the connection structure. The setting of the triangular limiting blocks effectively limits and fixes the T-shaped pressing block, preventing it from sliding or coming out during the operation, ensuring the stability and safety of the connection structure.

[0015] Preferably, the first sealing mechanism includes a circular sealing plate slidably disposed on the outer circumferential surface of the female terminal for cleaning dust. An annular sliding groove is formed in the middle of the circular sealing plate, and an annular scraping knife for scraping foreign matters on the surface of the female terminal is fixedly provided on one side of the annular sliding groove.

[0016] By adopting the above technical solution, the sliding design of the circular sealing plate on the outer circumferential surface of the female terminal enables it to flexibly adapt to the docking and splitting processes of the female connector and the male connector. The arrangement of the annular sliding groove and the annular scraping knife effectively scrapes and cleans the foreign matters and dust on the surface of the female terminal, ensuring the cleanliness and stability of signal transmission. At the same time, the circular sealing plate can also seal the docking interface between the female connector and the male connector during docking to prevent dust and sundries from entering.

[0017] Preferably, a special-shaped groove is formed on one side of the middle of the circular sealing plate. A special-shaped sealing plate that is rotatably disposed in the special-shaped groove and abuts against the insertion interface of the female terminal to achieve flipping is provided. The second sealing mechanism is arranged in the male connector according to the same setting method as the above first sealing mechanism.

[0018] By adopting the above technical solution, the special-shaped groove provides a chamber for the special-shaped sealing plate to rotate, enabling it to flip smoothly when abutting against the female terminal.

[0019] Preferably, a compression spring B fixedly connected to the inner cavity of the female connector is fixedly provided on one side of the circular sealing plate. The compression spring B is used to reset the circular sealing plate.

[0020] By adopting the above technical solution, the arrangement of the compression spring B enables the circular sealing plate to automatically reset after the female connector and the male connector are split, preparing for the next docking. This design not only improves the operation convenience of the connection structure but also extends the service life of the circular sealing plate.

[0021] Preferably, a plurality of horizontally arranged cross bars are fixedly provided on one side of the circular sealing plate away from the compression spring B. A fixing frame abutting against the second sealing mechanism is fixedly provided on one side of the cross bars.

[0022] By adopting the above technical solution, the arrangement of the cross bars and the fixing frame enhances the connection strength between the circular sealing plate and the second sealing mechanism, preventing the circular sealing plate from shaking or coming off during operation. At the same time, the horizontally arranged cross bars also improve the stability and balance of the circular sealing plate, ensuring the reliability of the sealing effect.

[0023] Preferably, an insulator is fixedly provided on the outer side of one side of the male terminal. An anti-slip grip is fixedly provided on one side of the insulator. A compression spring A for resetting the male connector is sleeved on the outer side of one side of the anti-slip grip.

[0024] By adopting the above technical solution, the setting of the insulator effectively prevents electrical short - circuits between the male terminal and surrounding metal components, improving the safety of the connection structure. The design of the anti - slip grip facilitates the operation of inserting and removing the male connector by the operator, improving the operation efficiency. The setting of the compression spring A enables the male connector to automatically reset after disassembly, preparing for the next docking, further improving the operation convenience and service life of the connection structure.

[0025] In summary, the present application includes at least one of the following beneficial technical effects: 1. By using the circular sealing plate in the second sealing mechanism to abut against the fixed frame, the fixed frame is pushed and the circular sealing plate is driven by the cross - bar to move into the inner cavity of the female connector, causing the annular sliding groove and the annular scraper to slide synchronously. At the same time, the female terminal abuts against the special - shaped sealing plate to make it flip in the special - shaped groove, enabling the annular sliding groove and the annular scraper to slide on the outer ring surface of the female terminal and compress the compression spring. When separating, under the action of the compression spring, the circular sealing plate is pushed to the docking port of the female connector for sealing, and the special - shaped sealing plate resets and is clamped and sealed with the annular sliding groove, thereby preventing dust from entering the female connector, avoiding the influence of dust on the electrical performance of the female terminal, preventing problems such as an increase in contact resistance and an increase in insertion loss, and ensuring the stable electrical performance of the RF power connector after multiple disassembly and assembly or long - term non - connection.

[0026] 2. By docking the male connector with the female connector, rotating the male connector to make the L - shaped block engage and be limited with the L - shaped sliding groove and the anti - detachment block, and then using the L - shaped limiting block to abut and limit the L - shaped block, the male connector and the female connector are fixedly connected. When separating, press the T - shaped pressing block, push the connecting rod A to make the sliding ring A, the sliding ring B and the connecting rod B in a horizontal state with the male terminal, thereby separating the female terminal from the male terminal. Then rotate the male connector to disengage the L - shaped block, and at the same time, the second sealing mechanism is sealed with the male connector, thus realizing the quick disassembly and assembly of the male connector and the female connector, and reducing the possibility of deformation of the inner conductor or outer conductor and loosening of the inner conductor welding due to uneven operating force, improving the use reliability and service life of the RF power connector.

Detailed implementation manners

[0029] The following further describes the present application in detail Figures 1 - 8 with reference to the accompanying drawings.

[0030] An embodiment of the present application discloses a quick-release connection structure for a radio frequency power supply connection port.

[0031] Referring to Figures 1 - 5 , a quick-release connection structure for a radio frequency power supply connection port includes a female connector 100 and a male connector 101, and an inner concave outer ring groove 105 is formed on the circumferential surface of the opening of the female connector 100, and an inner ring insert 106 is fixedly arranged on the circumferential surface of the opening of the male connector 101. The inner diameter of the outer ring groove 105 is the same as the outer diameter of the inner ring insert 106. Thus, by inserting the inner ring insert 106 into the outer ring groove 105, the female connector 100 and the male connector 101 can be plugged and sealed with each other. On one side of the inner wall of the L-shaped block 104, a plurality of L-shaped blocks 104 with the same structure are fixedly arranged, and the plurality of L-shaped blocks 104 are symmetrically arranged on the circumferential surface of the outer ring groove 105. The number of the plurality of L-shaped blocks 104 should be greater than two, and two is the best. Referring to Figures 1 - 5, on one side of the inner cavity of the female connector 100, an insulator 107 made of insulating material is slidably arranged, and a male terminal 103 is fixedly penetrated through the middle of the insulator 107. In the middle of the inner cavity of the female connector 100, a female terminal 102 with a hollow inner cavity is fixedly arranged, and the inner diameter of the female terminal 102 is the same as the outer diameter of the male terminal 103, so that the female terminal 102 can be inserted into and frictionally fixed with the male terminal 103, thereby realizing the transmission of signals. On the side of the insulator 107 away from the male terminal 103, an anti-slip grip 109 is fixedly arranged, and a compression spring A 108 is sleeved on the outer ring surface of the anti-slip grip 109 on the side of the male connector 101. The two ends of the compression spring A 108 are respectively abutted against the anti-slip grip 109 and the opposite side surface of the male connector 101, thereby realizing the reset of the male connector 101. The elastic force calculation formula of the compression spring A 108 and the compression spring B 110 is F = kx, where F represents the spring elastic force, k represents the spring constant (the elastic force generated by the spring under force per unit length), and x represents the spring compression amount (the displacement distance of the spring from the original state to the compressed state). The elastic force of the compression spring A 108 can be calculated by this formula.

[0032] It should be noted that the female terminal 102, the male terminal 103, the insulator 107, and the compression spring A 108 are all prior arts, and their structural principles will not be elaborated here. Both the female terminal 102 and the male terminal 103 are made of materials with good electrical conductivity such as brass, and the compression coefficient of the compression spring A 108 can be customized according to the actual situation from Shanghai Xianqi Precision Spring Custom Manufacturing Factory, but since they are all prior arts, their structural principles will not be elaborated here.

[0033] Insert the inner ring insert 106 on the male connector 101 into the outer ring groove 105 at the opening of the female connector 100, thereby realizing the insertion and sealing of the male connector 101 to the female connector 100. The insulator 107 slidably arranged in the inner cavity of the female connector 100 and the male terminal 103 fixedly penetrated through the middle of it can be pushed by the anti-slip grip 109 fixedly arranged on the other side of the insulator 107. When the female connector 100 and the male connector 101 are inserted into each other, the female terminal 102 and the male terminal 103 are on the same horizontal line. Then, by pushing the anti-slip grip 109, the male terminal 103 can be inserted into the female terminal 102. Since the inner diameter of the female terminal 102 is the same as the outer diameter of the male terminal 103, the two are closely matched and fixed to each other through mutual friction, thereby realizing the stable transmission of signals.

[0034] When disassembling, the male terminal 103 can be pulled out from the inner cavity of the female terminal 102 through the anti-slip grip 109. At the same time, the tail end of the male connector 101 abuts against the tail end of the insulator 107 and then separates from the female connector 100 under the pulling force of the anti-slip grip 109. When the anti-slip grip 109 is released, the compression spring A 108 pushes the male connector 101 to reset under its own elastic force and completely covers the front end of the male terminal 103, thereby facilitating the second sealing mechanism 300 to seal the opening of the male connector 101 and preventing dust from entering the inner cavity of the male connector 101.

[0035] Refer to Figures 2 - 5 - Figure 8 , a transverse abutting mechanism 200 is arranged in the inner cavity of the male connector 101, which is used to cooperate with the L-shaped block 104 to realize the abutting and limiting of the female connector 100 and the male connector 101, so as to fix the female connector 100 and the male connector 101. The transverse abutting mechanism 200 includes a sliding ring A 201 slidably arranged on the outer ring surface of the male terminal 103 on one side of the insulator 107, and the sliding ring A 201 is fixedly connected to the insulator 107. A plurality of link rods A 202 with the same structure are rotatably arranged on the sliding ring A 201. The number of the plurality of link rods A 202 is greater than two, and two is the best. And the plurality of link rods A 202 are symmetrically arranged on the sliding ring A 201. A link rod B 203 is rotatably arranged on one side of the plurality of link rods A 202 away from the sliding ring A 201, and the structures of the plurality of link rods B 203 are the same as those of the link rods A 202.

[0036] Refer to Figures 2 - 5 - Figure 8 , a sliding ring B 204 is rotatably arranged on one side of the link rod B 203 away from the link rod A 202. The sliding ring B 204 is slidably arranged on the outer ring surface of the male terminal 103 and has the same structure as and is symmetrical to the sliding ring A 201. When the sliding ring A 201 and the sliding ring B 204 approach each other, the link rod A 202 and the link rod B 203 can be folded, so as to lift the L-shaped limiting block 205 abutted on the upper ends of the link rod A 202 and the link rod B 203. An L-shaped limiting block 205 is provided with a limiting groove 206 opened on the inner ring surface of the male connector 101 on one side away from the link rod B 203 and the link rod A 202, and the L-shaped limiting block 205 is rotatably arranged in the limiting groove 206. A torsion spring is arranged at the connection between the L-shaped limiting block 205 and the limiting groove 206. When the L-shaped limiting block 205 is pushed by the link rod A 202 and the link rod B 203, it can fit with the limiting groove 206. The surface of the side of the L-shaped limiting block 205 abutting against the link rod A 202 is flush with the inner ring surface of the male connector 101. At the same time, when the abutting is lost, the L-shaped limiting block 205 will separate from the limiting groove 206 under the action of the torsion spring.

[0037] Refer to Figures 2 - 5 - Figure 8, and an L-shaped sliding groove 207 is provided on the side of the limiting groove 206 located at the opening of the male connector 101. The depth of the inner cavity of the L-shaped sliding groove 207 is greater than the depth of the inner cavity of the limiting groove 206, and the inner cavities of the two are interconnected. A retaining block 208 is fixedly provided on the side of the L-shaped sliding groove 207 located at the opening of the male connector 101. A distance for the L-shaped clamping block 104 to slide and be clamped is left between the retaining block 208 and the L-shaped sliding groove 207. Thus, the L-shaped clamping block 104 can slide and be inserted into the L-shaped sliding groove 207, and cannot be pulled out in the reverse direction under the action of the retaining block 208. Then, the L-shaped limiting block 205 rotatably arranged in the inner cavity of the limiting groove 206 is pushed by the connecting rod A 202 and the connecting rod B 203, so that the protruding end of the L-shaped limiting block 205 can be clamped in the L-shaped sliding groove 207 (as Figure 7 shown), so that one side surface of the L-shaped clamping block 104 slidably clamped in the L-shaped sliding groove 207 and the retaining block 208 abuts against one side surface of the L-shaped limiting block 205 clamped in the L-shaped sliding groove 207, thereby realizing the limit and preventing the L-shaped clamping block 104 from disengaging from the L-shaped sliding groove 207, which may cause the female connector 100 and the male connector 101 to separate.

[0038] Refer to Figures 2 - 5 - Figure 8, and a vertical slide groove 211 is provided on the side of the limit groove 206 away from the L-shaped slide groove 207, and the vertical slide groove 211 is fixedly passed through the male joint 101, and the vertical slide groove 211 is inclined, and the inclination angle is between 30°-45°, and a T-shaped pressing block 209 is slidably provided in the inner cavity of the vertical slide groove 211, and the lower end of the T-shaped pressing block 209 can abut against the upper end of one side surface of the connecting rod A202, so that when the connecting rod A202 is folded and lifted, the L-shaped slide groove 207 can be pushed in the vertical slide groove 211 toward the male joint 101 The T-shaped pressing block 209 slides outward, and triangular limiting blocks 210 with the same structure are arranged on both sides of the surface of the T-shaped pressing block 209 on one side of the connecting rod A202, so that the upper end of the triangular limiting block 210 abuts against the inner cavity of the male connector 101 during the movement of the slip ring A201 toward the outside of the male connector 101, thereby limiting the T-shaped pressing block 209 and preventing it from escaping from the inner cavity of the male connector 101. At the same time, pressing the T-shaped pressing block 209 toward the inner cavity of the male connector 101 can make the T-shaped pressing block 209 push the connecting rod A202 to move toward the male terminal 103. The length of the T-shaped pressing block 209 can be sufficient to push the folded connecting rod A202 to fit the outer ring surface of the male terminal 103 and be in a horizontal state, and when the triangular limiting block 210 abuts against the inner wall of the male connector 101, the connecting rod A202 and the connecting rod B203 can push the L-shaped limiting block 205 into the limiting groove 206 to limit the L-shaped block 104, and the slip ring A201 and the slip ring B204 are located on the same horizontal line, and the connecting rod A202 and the connecting rod B203 set on both can push the L-shaped limiting block 205 and the male connector 10 1, and then the connecting rod A202 and the connecting rod B203 are in contact with the inner wall of the male connector 101 to limit the position, so that the slip rings A201 and the slip rings B204 can be supported, and the slip rings A201 and the slip rings B204 can be kept at the same level as the male connector 101, so that the slip rings A201 and the slip rings B204 can guide and support the female terminal 102 and the male terminal 103 for plugging, and at the same time, the male terminal 103 can always be at the same level as the male connector 101 to prevent the male terminal 103 from being distorted.

[0039] Reference Figures 2 - 5 - Figure 8 , and a second sealing mechanism 300 is provided at the interface of the male connector 101, and the second sealing mechanism 300 can be used to scrape and clean the outer ring surface of the male terminal 103, and the side of the slip ring B204 away from the slip ring A201 is fixedly connected to the surface of one side of the circular sealing plate 301 in the second sealing mechanism 300 (such as Figure 5As shown, when the surface of the circular sealing plate 301 away from the slip ring B204 can be in contact with the fixing frame 111, a reverse support can be provided for the slip ring B204, so that the slip ring A201 and the slip ring B204 can approach each other under the push of the insulator 107, and then the link A202 and the link B203 can be pushed to fold up and down. In the separated state, the opening of the male connector 101 completely wraps the male terminal 103, and the second sealing mechanism 300 is located at the opening of the male connector 101, thus sealing and dust-proofing the inner cavity of the male connector 101. At the same time, the slip ring A201 and the slip ring B204, as well as the link A202 and the link B203, are all in the same horizontal state as the male terminal 103, so as to support and limit the second sealing mechanism 300 and prevent it from detaching from the opening of the male connector 101, thus preventing the loss of the sealing effect.

[0040] First, align the L-shaped block 104 with the openings of the L-shaped chute 207 and the anti-detachment block 208, then dock the female connector 100 with the male connector 101, insert the L-shaped block 104 into the L-shaped chute 207, and then rotate the male connector 101 to make the L-shaped block 104 engage and be limited with the L-shaped chute 207 and the anti-detachment block 208. Then, when the anti-slip grip 109 pushes the insulator 107 and further pushes the male terminal 103 to move towards the female terminal 102, the insulator 107 can push the slip ring A201 to move together, thereby driving the link A202 and the link B203 to push the slip ring B204 and the second sealing mechanism 300. When the second sealing mechanism 300 abuts against the fixing frame 111, the subsequent thrust drives the slip ring A201 to continue moving, while the slip ring B204 receives a reverse force because the circular sealing plate 301 abuts against the fixing frame 111, so that the slip ring B204 and the slip ring A201 can approach each other, and at the same time, one end of the link A202 and the link B203 approaches each other, so that the transfer end of the link A202 and the link B203 can move longitudinally. During the movement of the transfer end of the link A202 and the link B203, it will abut against the side surface of the L-shaped limit block 205, thereby driving the L-shaped limit block 205 to rotate into the limit groove 206 until the L-shaped limit block 205 completely enters the limit groove 206 and the protruding end of the L-shaped limit block 205 engages with the inner cavity of the L-shaped chute 207, thereby realizing the engagement and limitation of the L-shaped block 104, and at the same time, realizing the engagement and fixation of the female connector 100 and the male connector 101. The special-shaped sealing plate 302 arranged in the middle of the circular sealing plate 301 in the second sealing mechanism 300 is pushed by the male terminal 103, so as to be turned over, so that the outer ring surface of the male terminal 103 is in contact with and slides along the annular scraping knife 305 and the annular chute 304 arranged in the middle of the circular sealing plate 301, so that the annular chute 304 and the annular scraping knife 305 clean the outer ring surface of the male terminal 103 and scrape off foreign objects.

[0041] Meanwhile, when the connecting rod A202 moves longitudinally, it will abut against one side surface of the T-shaped pressing block 209 and push the T-shaped pressing block 209 to move within the vertical sliding groove 211 until the triangular limiting block 210 abuts against the inner wall of the male connector 101. At this time, the male terminal 103 and the female terminal 102 are also plugged and fixed. When it is necessary to separate the female terminal 102 from the male terminal 103, just press the T-shaped pressing block 209 to move the T-shaped pressing block 209 into the inner cavity of the male connector 101. Then, the T-shaped pressing block 209 pushes the connecting rod A202 to move, so that the connecting rod A202 exerts a thrust on the connecting rod B203 and the slip ring A201. Since the slip ring B204 is fixed, this force will cause the connecting rod A202 and the connecting rod B203 to move towards the male terminal 103 side, and at the same time push the slip ring A201 and the insulator 107 to move, thereby driving the separation of the male terminal 103 and the female terminal 102. The L-shaped limiting block 205 that loses the abutment of the connecting rod A202 and the connecting rod B203 will be separated from the limiting groove 206, so that the L-shaped locking block 104 can be released from the limit. Then, rotate the male connector 101 so that the L-shaped locking block 104 can be disengaged from the L-shaped sliding groove 207 and the anti-disengagement block 208, thereby realizing the separation of the female connector 100 and the male connector 101.

[0042] Refer to Figures 2 - 4 , a first sealing mechanism 300 is provided at the interface of the female connector 100, and the first sealing mechanism 300 can be used to scrape and clean foreign matters and dust on the outer ring surface of the female terminal 102. The structure of the first sealing mechanism 300 is the same as that of the second sealing mechanism 300, and the first sealing mechanism 300 can seal the interface of the female connector 100 during disassembly. Similarly, the second sealing mechanism 300 can seal the interface of the male connector 101 during disassembly. The first sealing mechanism 300 includes a circular sealing plate 301 slidably arranged on the outer ring surface of the female terminal 102, and a circular sliding groove 304 is fixedly penetrated through the middle of the circular sealing plate 301. An annular scraping knife 305 is fixedly arranged on one side of the circular sliding groove 304, and the annular scraping knife 305 can be a ceramic scraping knife. The inner ring diameters of the circular sliding groove 304 and the annular scraping knife 305 are the same as the outer ring diameter of the female terminal 102, so that the circular sliding groove 304 and the annular scraping knife 305 can both be slidably arranged on the outer ring surface of the female terminal 102 to clean the dust on the outer ring surface of the female terminal 102 and scrape off the foreign matters protruding from the surface of the female terminal 102.

[0043] Refer to Figures 2 - 4, a special-shaped groove 303 is provided in the middle of the circular sealing plate 301 at one side of the upper end of the annular chute 304. An irregular-shaped sealing plate 302 is clamped and arranged on the side of the annular chute 304 away from the annular scraper 305. The irregular-shaped sealing plate 302 is rotatably arranged in the special-shaped groove 303. A torsion spring is arranged at the transition position between the irregular-shaped sealing plate 302 and the special-shaped groove 303 to help the irregular-shaped sealing plate 302 reset. The irregular-shaped sealing plate 302 abuts against the insertion port of the female terminal 102 to realize flipping. One end of a compression spring B110 is fixedly connected to the surface of the circular sealing plate 301 away from the irregular-shaped sealing plate 302, and the other end of the compression spring B110 is fixedly connected to the inner cavity side wall of the female connector 100. The compression spring B110 and the compression spring A108 are set with the same coefficient and are used to reset the circular sealing plate 301 after compression. The surface of the circular sealing plate 301 away from the compression spring B110 is fixedly connected to a number of cross bars 112 with the same structure. The cross bars 112 are arranged in an array on the surface of the circular sealing plate 301. A fixing frame 111 with a diameter smaller than the outer diameter of the circular sealing plate 301 and larger than the diameter of the annular chute 304 is fixedly arranged on the surface of the cross bar 112 away from the circular sealing plate 301. The side of the fixing frame 111 away from the cross bar 112 abuts against and limits the circular sealing plate 301 in the second sealing mechanism 300.

[0044] When the circular sealing plate 301 in the second sealing mechanism 300 abuts against the fixing frame 111, it will push the fixing frame 111, and then drive the circular sealing plate 301 to move into the inner cavity of the female connector 100 through the cross bar 112. Then, the annular chute 304 and the annular scraper 305 slide synchronously on the outer ring surface of the female terminal 102. At the same time, the female terminal 102 abuts against the irregular-shaped sealing plate 302, causing the irregular-shaped sealing plate 302 to flip in the special-shaped groove 303. Thus, the circular sealing plate 301 can penetrate through the female terminal 102 through the annular chute 304, compressing the compression spring B110 to prepare for subsequent reset. When the female connector 100 is separated from the male connector 101, the compression spring B110 pushes the circular sealing plate 301 to the docking port of the female connector 100 for sealing. At the same time, the irregular-shaped sealing plate 302 is reset under the action of the torsion spring and is clamped and sealed with the annular chute 304 to prevent dust from entering the female connector 100, affecting the electrical performance of the female terminal 102 and causing an increase in resistance and insertion loss.

[0045] The implementation principle of a quick-release connection structure for a radio frequency power supply connection port in an embodiment of the present application is as follows: First, align the inner ring insert 106 on the male connector 101 with the outer ring groove 105 at the opening of the female connector 100, align the L-shaped latch 104 with the openings of the L-shaped sliding groove 207 and the anti-disengagement block 208, and dock the female connector 100 with the male connector 101. Then, rotate the male connector 101 so that the L-shaped latch 104 is snapped into the L-shaped sliding groove 207 and the anti-disengagement block 208. At the same time, push the insulator 107 and the male terminal 103 towards the female terminal 102 through the anti-slip grip 109, thereby driving the slip ring A201 to move together, and driving the link A202 and the link B203 to push the slip ring B204 and the second sealing mechanism 300. Furthermore, drive the L-shaped limiting block 205 at one end of the link A202 and the link B203 to rotate into the limiting groove 206 until the L-shaped limiting block 205 is snapped into the inner cavity of the L-shaped sliding groove 207, thereby realizing the snap-limiting of the L-shaped latch 104 and simultaneously realizing the snap-fixing of the female connector 100 and the male connector 101. At the same time, the link A202 will push the T-shaped pressing block 209 to move in the vertical sliding groove 211 until the triangular limiting block 210 abuts against the inner wall of the male connector 101.

[0046] Meanwhile, when the circular sealing plate 301 in the second sealing mechanism 300 abuts against the fixing frame 111, it will push the fixing frame 111 and then drive the circular sealing plate 301 to move into the inner cavity of the female connector 100 through the cross bar 112, thereby enabling the annular sliding groove 304 and the annular scraper 305 to slide synchronously. At the same time, the female terminal 102 abuts against the special-shaped sealing plate 302, causing the special-shaped sealing plate 302 to flip in the special-shaped groove 303, so that the annular sliding groove 304 and the annular scraper 305 can slide on the outer ring surface of the female terminal 102, and simultaneously compress the compression spring B110. At this time, the male terminal 103 and the female terminal 102 are also plugged and fixed.

[0047] When it is necessary to separate the female connector 100 from the male connector 101, press the T-shaped pressing block 209 to move into the inner cavity of the male connector 101, thereby driving the link A202 to move. The link A202 drives the slip ring A201 and the insulator 107 to move backward, thereby driving the male terminal 103 to separate from the female terminal 102. The L-shaped limiting block 205 will separate from the limiting groove 206. Then, rotate the male connector 101 so that the L-shaped latch 104 disengages from the L-shaped sliding groove 207 and the anti-disengagement block 208, thereby realizing the separation of the female connector 100 and the male connector 101.

[0048] Under the action of the compression spring B110, the circular sealing plate 301 is pushed to the butting port of the female connector 100 for sealing. At the same time, the special-shaped sealing plate 302 resets and is clamped and sealed with the annular sliding groove 304 to prevent dust from entering the female connector 100 and affecting the electrical performance of the female terminal 102, as well as causing an increase in resistance and an increase in insertion loss. At the same time, under the action of the compression spring A108, the male connector 101 is pushed to reset, and the slip ring A201, the slip ring B204, the connecting rod A202, and the connecting rod B203 are in a horizontal state with the male terminal 103 under the pressing of the T-shaped pressing block 209. Furthermore, the second sealing mechanism 300 is located at the front end of the male terminal 103 and seals the butting port of the male connector 101.

[0049] The annular scraper 305 provided in the middle of the circular sealing plate 301 in the second sealing mechanism 300 is in contact with and slides along the annular sliding groove 304 and the male terminal 103. Furthermore, the annular sliding groove 304 and the annular scraper 305 clean the outer ring surface of the male terminal 103 and scrape off foreign objects.

[0050] The above are only optional embodiments of the present disclosure and are not used to limit the present disclosure. For those skilled in the art, various changes and modifications can be made to the present disclosure. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present disclosure shall be included within the protection scope of the present disclosure.
