After the contact ring contacts the inner wall of the circular ring groove, the male RF connector can be limited through the protective cylinder, avoiding damage to the male RF connector and the female RF connector due to excessive force during plugging.
[0015] When the limiting ring enters the inner part of the circular ring groove in the present invention, its end will contact the inclined surface of the inclined block. When the limiting ring moves, it will push the inclined block to squeeze the elastic rod through the inclined surface of the inclined block. At this time, the inclined block can slide on the surface of the limiting ring through the sliding hole. When the inclined block corresponds to the inner wall of the fixing hole, the inclined block uses the elasticity of the elastic rod to squeeze the inner wall of the fixing hole, thereby fixing the male RF connector and the female RF connector, improving the stability after the male RF connector and the female RF connector are plugged. When it is necessary to disassemble the male RF connector and the female RF connector, the limiting ring drives the fixing hole to squeeze the inclined surface of the inclined block during movement, thereby pushing the inclined block to squeeze the elastic rod to separate it from the inner wall of the fixing hole to complete the disassembly, improving the convenience of the male RF connector and the female RF connector during use.

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.
[0021] Please refer to Figures 1-7As shown in the figure, the present invention is a quick-insert type RF connector, which includes a male RF connector 1. One end of the male RF connector 1 is inserted with a female RF connector 2. Cables 3 are fixedly connected to the ends of the male RF connector 1 and the female RF connector 2 that are away from each other. A circular ring groove 4 is opened at one end of the female RF connector 2 close to the male RF connector 1. A positioning groove 5 is opened on the inner wall of the female RF connector 2. A protective component 6 is provided at one end of the female RF connector 2 and the male RF connector 1 that are close to each other. The protective component 6 includes a protective cylinder 10. One end of the protective cylinder 10 is fixedly connected to the end of the male RF connector 1. A protective pad 11 is fixedly connected to the inner wall of the protective cylinder 10. After the male RF connector 1 and the female RF connector 2 are inserted, the male RF connector 1 will push the insertion ring 12 into the interior of the circular ring groove 4 through the protective cylinder 10 for insertion and fixation. When the insertion ring 12 contacts the inner wall of the circular ring groove 4, the protective cylinder 10 will wrap the insertion ends of the male RF connector 1 and the female RF connector 2. One end of the protective cylinder 10 away from the male RF connector 1 is fixedly connected with an insertion ring 12. A sealing ring 18 is fixedly connected to the surface of the insertion ring 12. A circular rubber ring 16 is fixedly connected to the surface of the sealing ring 18. A sealing groove 19 is opened at the end of the female RF connector 2. After the insertion ring 12 contacts the inner wall of the circular ring groove 4, the sealing ring 18 will squeeze the circular rubber ring 16 to insert into the interior of the sealing groove 19, and the circular rubber ring 16 is used to seal the protective cylinder 10. A stabilizing groove 13 is opened on the inner wall of the insertion ring 12. A triangular block 17 is fixedly connected to the inner wall of the stabilizing groove 13. A stabilizing ring 14 is fixedly connected to the inner wall of the circular ring groove 4. A triangular groove 15 is opened on the surface of the stabilizing ring 14. An installation component 7 is provided at one end of the insertion ring 12 away from the protective cylinder 10. A fixing component 8 is arranged inside the circular ring groove 4.
[0022] The positioning groove 5 communicates with the circular ring groove 4. When the stabilizing ring 14 contacts the inner wall of the stabilizing groove 13, the surface of the triangular block 17 will also contact the inner wall of the triangular groove 15. The stabilizing ring 14, the triangular groove 15 and the insertion ring 12 are used for positioning and extrusion to improve the stability of the insertion ring 12 after insertion. The inner wall of the protective pad 11 contacts the insertion end of the male RF connector 1, and the surface of the insertion ring 12 is inserted into the inner wall of the circular ring groove 4.
[0023] The number of the sealing rings 18 is set to two. The two sealing rings 18 are symmetrically arranged with the protective cylinder 10 as the center. The sealing rings 18 are located at one end of the insertion ring 12 close to the protective cylinder 10. One end of the sealing ring 18 close to the insertion ring 12 contacts the end of the female RF connector 2.
[0024] The surface of the circular rubber ring 16 contacts the inner wall of the sealing groove 19. The surface of the stabilizing ring 14 contacts the inner wall of the stabilizing groove 13. The surface of the triangular block 17 contacts the inner wall of the triangular groove 15.
[0025] The installation component 7 includes a limit ring 20. The end of the limit ring 20 is fixedly connected to the end of the insertion ring 12. A contact ring 21 is fixedly connected to the end of the limit ring 20 away from the insertion ring 12. A sliding hole 22 is formed on the surface of the contact ring 21, and a fixing hole 23 is formed on the surface of the limit ring 20.
[0026] The limit ring 20 is located at the end of the insertion ring 12 away from the protective cylinder 10. When the insertion ring 12 contacts the inner wall of the circular ring groove 4, the insertion ring 12 will push the limit ring 20 into the interior of the circular ring groove 4. After the limit ring 20 enters the interior of the circular ring groove 4, it pushes the contact ring 21 to contact the inner wall of the circular ring groove 4. The sliding hole 22 and the fixing hole 23 correspond to each other, and the surface of the contact ring 21 contacts the inner wall of the circular ring groove 4.
[0027] The limit ring 20 is located inside the circular ring groove 4. After the contact ring 21 contacts the inner wall of the circular ring groove 4, the protective cylinder 10 can limit the radio frequency connection male head 1 to prevent damage to the radio frequency connection male head 1 due to excessive force during the insertion of the radio frequency connection male head 1 and the radio frequency connection female head 2. The number of fixing holes 23 is set to four, and the four fixing holes 23 are arranged circumferentially with the limit ring 20 as the center.
[0028] The fixing component 8 includes a reinforcing ring 30. The surface of the reinforcing ring 30 is fixedly connected to the inner wall of the positioning groove 5. A circular groove 31 is formed on the inner wall of the reinforcing ring 30. A bevel block 33 is inserted into the inner wall of the fixing hole 23. When the limit ring 20 enters the interior of the circular ring groove 4, the end of the limit ring 20 will contact the bevel of the bevel block 33. When the limit ring 20 moves, it pushes the bevel block 33 through the bevel to squeeze the elastic rod 32. At this time, the bevel block 33 can slide on the surface of the limit ring 20 through the sliding hole 22. A elastic rod 32 is fixedly connected to the end of the bevel block 33 away from the fixing hole 23. When the bevel block 33 corresponds to the inner wall of the fixing hole 23, the bevel block 33 uses the elasticity of the elastic rod 32 to squeeze the inner wall of the fixing hole 23, thereby fixing the radio frequency connection male head 1 and the radio frequency connection female head 2. The end of the elastic rod 32 away from the bevel block 33 is fixedly connected to the inner wall of the circular groove 31.
[0029] The number of bevel blocks 33 is set to four. When it is necessary to disassemble the radio frequency connection male head 1 and the radio frequency connection female head 2, the limit ring 20 drives the fixing hole 23 to squeeze the bevel of the bevel block 33 when moving, thereby pushing the bevel block 33 to squeeze the elastic rod 32 to separate it from the inner wall of the fixing hole 23 to complete the disassembly. The four bevel blocks 33 are arranged circumferentially with the reinforcing ring 30 as the center, and the end of the bevel block 33 close to the elastic rod 32 extends to the outer end of the fixing hole 23.
[0030] When in use, after the male RF connector 1 is inserted into the female RF connector 2, the male RF connector 1 will push the insertion ring 12 into the inside of the circular ring groove 4 through the protective cylinder 10 for insertion and fixation. When the insertion ring 12 contacts the inner wall of the circular ring groove 4, the protective cylinder 10 will wrap the insertion ends of the male RF connector 1 and the female RF connector 2, and use the protective cylinder 10 to protect them, avoiding the deformation of the insertion ends of the male RF connector 1 and the female RF connector 2 due to force. After the insertion ring 12 contacts the inner wall of the circular ring groove 4, the sealing ring 18 will squeeze the circular rubber ring 16 into the inside of the sealing groove 19, and seal the protective cylinder 10 through the circular rubber ring 16, avoiding the liquid entering the inside of the male RF connector 1 when it is used outside and causing damage. When the stabilizing ring 14 contacts the inner wall of the stabilizing groove 13, the surface of the triangular block 17 will also contact the inner wall of the triangular groove 15. Use the stabilizing ring 14, the triangular groove 15 and the insertion ring 12 for positioning and extrusion to improve the stability of the insertion ring 12 after insertion. When the male RF connector 1 and the female RF connector 2 are inserted, the sealing ring 18 can be pushed into the inside of the sealing groove 19, without separately sealing the male RF connector 1 and the female RF connector 2, improving the convenience of the sealing treatment of the male RF connector 1 and the female RF connector 2. When the insertion ring 12 contacts the inner wall of the circular ring groove 4, the insertion ring 12 will push the limiting ring 20 into the inside of the circular ring groove 4. After the limiting ring 20 enters the inside of the circular ring groove 4, it will push the contact ring 21 to contact the inner wall of the circular ring groove 4. After the contact ring 21 contacts the inner wall of the circular ring groove 4, the male RF connector 1 can be limited through the protective cylinder 10, avoiding damage to the male RF connector 1 and the female RF connector 2 due to excessive force during insertion. When the limiting ring 20 enters the inside of the circular ring groove 4, its end will contact the inclined surface of the inclined block 33. When the limiting ring 20 moves, it will push the inclined block 33 to squeeze the elastic rod 32 through the inclined surface of the inclined block 33. At this time, the inclined block 33 can slide on the surface of the limiting ring 20 through the sliding hole 22. When the inclined block 33 corresponds to the inner wall of the fixing hole 23, the inclined block 33 uses the elasticity of the elastic rod 32 to squeeze the inner wall of the fixing hole 23, thereby fixing the male RF connector 1 and the female RF connector 2 and improving the stability of the male RF connector 1 and the female RF connector 2 after insertion. When it is necessary to disassemble the male RF connector 1 and the female RF connector 2, the limiting ring 20 drives the fixing hole 23 to squeeze the inclined surface of the inclined block 33 during movement, thereby pushing the inclined block 33 to squeeze the elastic rod 32 to separate it from the inner wall of the fixing hole 23 to complete the disassembly, improving the convenience of the male RF connector 1 and the female RF connector 2 during use.
