[0007] The protective component includes a protective tube, the end of the protective tube is fixedly connected to the end of the RF connection male head, the inner wall of the protective tube is fixedly connected to a protective pad, the end of the protective tube away from the RF connection male head is fixedly connected to a plug-in ring, the surface of the plug-in ring is fixedly connected to a sealing ring, the surface of the sealing ring is fixedly connected to a circular rubber ring, the end of the RF connection female head is provided with a sealing groove, the inner wall of the plug-in ring is provided with a stabilizing groove, the inner wall of the stabilizing groove is fixedly connected to a triangular block, the inner wall of the circular groove is fixedly connected to a stabilizing ring, the surface of the stabilizing ring is provided with a triangular groove, the end of the plug-in ring away from the protective tube is provided with a mounting component, and the inside of the circular groove is provided with a fixing component.

[0008] Furthermore, the positioning groove and the annular groove are connected to each other, the inner wall of the protective pad is in contact with the plug-in end of the RF connector, and the surface of the plug-in ring is plugged into the inner wall of the annular groove.

[0009] Furthermore, there are two sealing rings, which are symmetrically arranged with the protective tube as the center. The sealing ring is located at one end of the plug-in ring close to the protective tube, and the end of the sealing ring close to the plug-in ring contacts the end of the RF connector.

[0010] Furthermore, the surface of the circular rubber ring contacts the inner wall of the sealing groove, the surface of the stabilizing ring contacts the inner wall of the stabilizing groove, and the surface of the triangular block contacts the inner wall of the triangular groove.

[0011] Furthermore, the mounting component includes a limiting ring, the end of which is fixedly connected to the end of the plug-in ring, the end of the limiting ring away from the plug-in ring is fixedly connected to a contact ring, a sliding hole is provided on the surface of the contact ring, and a fixing hole is provided on the surface of the limiting ring.

[0012] Furthermore, the limiting ring is located at an end of the plug-in ring away from the protective tube, the sliding hole and the fixing hole correspond to each other, and the surface of the contact ring contacts the inner wall of the annular groove.

[0013] Furthermore, the limiting ring is located inside the annular groove, and there are four fixing holes, which are arranged around a circle with the limiting ring as the center.

[0014] Furthermore, the fixing component includes a reinforcement ring, the surface of the reinforcement ring is fixedly connected to the inner wall of the positioning groove, the inner wall of the reinforcement ring is provided with a circular groove, the inner wall of the fixing hole is plugged with a ramp block, the end of the ramp block away from the fixing hole is fixedly connected to an elastic rod, and the end of the elastic rod away from the ramp block is fixedly connected to the inner wall of the circular groove.

[0015] Furthermore, there are four inclined plane blocks, which are arranged around a central circumference of the reinforcement ring, and one end of the inclined plane block close to the elastic rod extends to the outer end of the fixing hole.

[0016] The present invention has the following beneficial effects:

[0017] After the RF connector male and RF connector female are plugged together, the RF connector male will push the plug ring into the inside of the circular groove through the protective tube for plugging and fixing. When the plug ring contacts the inner wall of the circular groove, the protective tube will wrap the plug ends of the RF connector male and RF connector female, and use the protective tube to protect them to avoid the plug ends of the RF connector male and RF connector female being deformed by force. After the plug ring contacts the inner wall of the circular groove, the sealing ring will squeeze the circular rubber ring and insert it into the interior of the sealing groove. The circular rubber ring will protect the protective ring. The tube is sealed to prevent liquid from entering the interior of the RF connector and causing damage when the RF connector is used in the outside world. When the stabilizing ring contacts the inner wall of the stabilizing groove, the surface of the triangular block also contacts the inner wall of the triangular groove. The stabilizing ring, the triangular groove and the plug-in ring are used for positioning and extrusion, thereby improving the stability of the plug-in ring after plugging in. When the RF connector male head and the RF connector female head are plugged in, the sealing ring can be pushed into the interior of the sealing groove, without the need to seal the RF connector male head and the RF connector female head separately, thereby improving the convenience of sealing the RF connector male head and the RF connector female head.

[0018] When the plug-in ring of the present invention contacts the inner wall of the circular groove, the plug-in ring will push the limiting ring into the interior of the circular groove. After the limiting ring enters the interior of the circular groove, it pushes the contact ring to contact the inner wall of the circular groove. After the contact ring contacts the inner wall of the circular groove, the protective tube can be used to limit the RF connector male head, thereby preventing the RF connector male head from being damaged due to excessive force when plugging the RF connector female head into the RF connector male head.

[0019] When the limiting ring of the present invention enters the interior of the annular groove, its end portion will contact the inclined surface of the inclined surface block. When the limiting ring moves, it pushes the inclined surface of the inclined surface block to squeeze the elastic rod. At this time, the inclined surface block can slide on the surface of the limiting ring through the sliding hole. When the inclined surface block corresponds to the inner wall of the fixing hole, the inclined surface block uses the elasticity of the elastic rod to squeeze the inner wall of the fixing hole, thereby fixing the RF connection male head and the RF connection female head, improving the stability of the RF connection male head and the RF connection female head after plugging in. When the RF connection male head and the RF connection female head need to be disassembled, the limiting ring drives the fixing hole to squeeze the inclined surface of the inclined surface block when moving, thereby pushing the inclined surface block to squeeze the elastic rod so that it is separated from the inner wall of the fixing hole to complete the disassembly, thereby improving the convenience of the RF connection male head and the RF connection female head when in use.

[0020] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

After the RF connector male head 1 and the RF connector female head 2 are plugged in, the RF connector male head 1 will push the plug ring 12 into the inside of the annular groove 4 through the protective tube 10 for plugging and fixing. When the plug ring 12 contacts the inner wall of the annular groove 4, the protective tube 10 will wrap the plug-in ends of the RF connector male head 1 and the RF connector female head 2. The end of the protective tube 10 away from the RF connector male head 1 is fixedly connected with the plug ring 12, and the surface of the plug ring 12 is fixedly connected with a sealing ring 18 for sealing. A circular rubber ring 16 is fixedly connected to the surface of the ring 18, and a sealing groove 19 is provided at the end of the RF connector female head 2. After the plug-in ring 12 contacts the inner wall of the circular groove 4, the sealing ring 18 will squeeze the circular rubber ring 16 and insert it into the inside of the sealing groove 19. The protective tube 10 is sealed by the circular rubber ring 16. A stabilizing groove 13 is provided on the inner wall of the plug-in ring 12, and a triangular block 17 is fixedly connected to the inner wall of the stabilizing groove 13.

[0034] The positioning groove 5 and the annular groove 4 are connected to each other. 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 plug-in ring 12 are positioned and extruded to improve the stability of the plug-in ring 12 after insertion. The inner wall of the protective pad 11 contacts the plug-in end of the RF connector male head 1, and the surface of the plug-in ring 12 is plugged into the inner wall of the annular groove 4.

[0035] There are two sealing rings 18 , which are symmetrically arranged with the protective tube 10 as the center. The sealing ring 18 is located at one end of the plug-in ring 12 close to the protective tube 10 , and the end of the sealing ring 18 close to the plug-in ring 12 contacts the end of the RF connector 2 .

[0036] 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 , and the surface of the triangular block 17 contacts the inner wall of the triangular groove 15 .

[0037] The mounting component 7 includes a limiting ring 20, the end of which is fixedly connected to the end of the plug-in ring 12, and the end of the limiting ring 20 away from the plug-in ring 12 is fixedly connected to a contact ring 21, a sliding hole 22 is provided on the surface of the contact ring 21, and a fixing hole 23 is provided on the surface of the limiting ring 20.

[0038] The limiting ring 20 is located at the end of the plug-in ring 12 away from the protective tube 10. When the plug-in ring 12 contacts the inner wall of the annular groove 4, the plug-in ring 12 will push the limiting ring 20 into the interior of the annular groove 4. After the limiting ring 20 enters the interior of the annular groove 4, it pushes the contact ring 21 to contact the inner wall of the annular 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 annular groove 4.

[0039] The limiting ring 20 is located inside the annular groove 4. After the contact ring 21 contacts the inner wall of the annular groove 4, the protective tube 10 can be used to limit the RF connector male head 1 to prevent the RF connector male head 1 from being damaged due to excessive force when plugging the RF connector male head 1 and the RF connector female head 2. There are four fixing holes 23, and the four fixing holes 23 are arranged around the limiting ring 20 as the center circumference.

[0040] When the locking cam 33 is in the unlock position, the locking cam 33 is locked and the locking cam 33 is unlocked, so that the cam 33 can be unlocked and locked.

[0041] There are four inclined plane blocks 33. When the RF connector male connector 1 and the RF connector female connector 2 need to be disassembled, the limiting ring 20 drives the fixing hole 23 to squeeze the inclined surface of the inclined plane block 33 when moving, thereby pushing the inclined plane block 33 to squeeze the elastic rod 32 so that it is separated from the inner wall of the fixing hole 23 to complete the disassembly. The four inclined plane blocks 33 are arranged with the reinforcement ring 30 as the center circumference, and the end of the inclined plane block 33 close to the elastic rod 32 extends to the outer end of the fixing hole 23.

[0042] When in use, after the RF connector male head 1 and the RF connector female head 2 are plugged in, the RF connector male head 1 will push the plug ring 12 into the inside of the annular groove 4 through the protective tube 10 for plugging and fixing. When the plug ring 12 contacts the inner wall of the annular groove 4, the protective tube 10 will wrap the plug-in ends of the RF connector male head 1 and the RF connector female head 2, and use the protective tube 10 to protect them to prevent the plug-in ends of the RF connector male head 1 and the RF connector female head 2 from being deformed by force. After the plug ring 12 contacts the inner wall of the annular groove 4, the sealing ring 18 will squeeze the circular rubber ring 16 and insert it into the interior of the sealing groove 19, and the protective tube 10 will be pressed by the circular rubber ring 16. A sealing process is performed to prevent liquid from entering the interior of the RF connector male head 1 and causing damage when the RF connector male head 1 is used in the outside world. When the stabilizing ring 14 contacts the inner wall of the stabilizing groove 13, the surface of the triangular block 17 also contacts the inner wall of the triangular groove 15. The stabilizing ring 14, the triangular groove 15 and the plug-in ring 12 are used to position and squeeze, thereby improving the stability of the plug-in ring 12 after plugging. When the RF connector male head 1 and the RF connector female head 2 are plugged in, the sealing ring 18 can be pushed into the interior of the sealing groove 19. There is no need to seal the RF connector male head 1 and the RF connector female head 2 separately, thereby improving the convenience of the sealing process of the RF connector male head 1 and the RF connector female head 2. The plug-in ring 12 and the circular groove 4 are tightly connected. When the inner wall contacts, the plug-in ring 12 will push the limiting ring 20 into the inside of the circular groove 4. After the limiting ring 20 enters the inside of the circular groove 4, it pushes the contact ring 21 to contact the inner wall of the circular groove 4. After the contact ring 21 contacts the inner wall of the circular groove 4, the protective tube 10 can be used to limit the RF connection male head 1 to avoid damage caused by excessive force when the RF connection male head 1 and the RF connection female head 2 are plugged in. When the limiting ring 20 enters the inside of the circular groove 4, its end will contact the inclined surface of the inclined surface block 33. When the limiting ring 20 moves, it pushes it to squeeze the elastic rod 32 through the inclined surface of the inclined surface block 33. At this time, the inclined surface block 33 can be limited in the position through the sliding hole 22. The surface of the ring 20 slides, and 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 RF connection male connector 1 and the RF connection female connector 2, improving the stability of the RF connection male connector 1 and the RF connection female connector 2 after plugging. When the RF connection male connector 1 and the RF connection female connector 2 need to be disassembled, 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, thereby improving the convenience of the RF connection male connector 1 and the RF connection female connector 2 when in use.
