Description

Technical Field

[0001] The invention relates to the technical field of radio frequency connectors, in particular to an anti-falling radio frequency connector. Background Art

[0002] RF connector is an electronic component used for high-frequency signal transmission. It is usually installed on a cable or instrument as a component for electrically connecting or separating transmission lines. Its main function is to connect or disconnect two RF ports when necessary to achieve electrical connection, separation, or transfer of different types of transmission lines.

[0003] Current RF connectors are generally connected by plugging, but the plugging end of the RF connector is relatively weak. When the RF connector is plugged in and out multiple times or the force is applied in the wrong direction, it is easy to cause its fit to decrease. The reduced fit will cause the RF connector to become loose after installation, affecting the stability of the RF connector for signal transmission. Summary of the invention

[0004] The object of the present invention is to provide a radio frequency connector that prevents falling off, so as to solve the problems raised in the above background technology.

[0005] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0006] The present invention is an anti-dropping radio frequency connector, comprising a radio frequency connection male head, an end of the radio frequency connection male head is plugged with a radio frequency connection female head, a cable is arranged at one end of the radio frequency connection male head and the radio frequency connection female head which are away from each other, and the surfaces of the radio frequency connection male head and the radio frequency connection female head are respectively provided with fixing components;

[0007] The fixing component includes a fixing ring, a limiting plate is fixedly connected to the surface of the fixing ring, a clamping frame is fixedly connected to one end of the limiting plate away from the fixing ring, a slot is provided on the inner wall of the clamping frame, a plug-in block is inserted into the inner wall of the slot, an elastic telescopic rod is fixedly connected to the surface of the plug-in block, a circular groove is provided inside the fixing ring, a sealing ring is fixedly connected to the inner wall of the circular groove, a locking component is provided on the surface of the fixing ring, and a sealing component is provided at the end of the fixing ring.

[0008] Furthermore, there are two fixing rings, the sealing rings inside the two fixing rings are in contact with the surface of the RF connector male head and the RF connector female head respectively, and the inner wall of the card holder is in contact with the surface of the cable.

[0009] Furthermore, the number of the insertion blocks is set to four. The four insertion blocks are set into two groups, and the number of each group is set to two. The elastic telescopic rod is located at one end where the two insertion blocks are close to each other, and the clamping frame is located at one end of the cable close to the male RF connector.

[0010] Furthermore, the locking component includes a round-hole rod. A round rod is slidably connected to the inner wall of the round-hole rod. A mounting plate is fixedly connected to the surface of the fixed ring. One end of the round-hole rod away from the round rod is fixedly connected to the mounting plate. One end of the round rod away from the round-hole rod is rotatably connected to the surface of the mounting plate. A jack is opened on the surface of the round-hole rod. A groove is opened on the surface of the round rod. An elastic rod is fixedly connected to the inner wall of the groove. One end of the elastic rod away from the groove is fixedly connected to a stabilizing plate. An inclined plate is hinged to one end of the stabilizing plate away from the elastic rod. A lock block is hinged to the top of the inclined plate. A telescopic rod is fixedly connected to the bottom of the lock block. The bottom of the telescopic rod is fixedly connected to the bottom of the inner wall of the groove.

[0011] Furthermore, the round-hole rod and the round rod are located at one end where the two fixed rings are close to each other. One end of the round rod close to the mounting plate extends to the outer end of the round-hole rod.

[0012] Furthermore, a plurality of jacks are opened on the top of the round-hole rod. Two elastic rods are arranged inside the groove. The two elastic rods are symmetrically arranged with the lock block as the center.

[0013] Furthermore, the surface of the stabilizing plate is slidably connected to the inner wall of the groove. One end of the inclined plate away from the stabilizing plate is arranged to be inclined upward. The surface of the lock block is in contact with the inner wall of the jack.

[0014] Furthermore, the sealing component includes a pressing ring. The surface of the pressing ring is fixedly connected to the end of the fixed ring. A pressing groove is opened at one end of the pressing ring away from the fixed ring. A rubber sleeve is inserted into the inner wall of the pressing groove.

[0015] Furthermore, the number of the pressing rings is set to two. The two pressing rings are symmetrically arranged with the rubber sleeve as the center. The rubber sleeve is located at one end where the male RF connector and the female RF connector are close to each other. The two pressing rings are located at one end where the two fixed rings are close to each other.

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

[0017] After inserting the male RF connector and the female RF connector into the inside of the fixing ring, the clamping frame is inserted on the surface of the cable. The clamping frame is located at one end where the cable and the male RF connector are close to each other. The clamping frame is used to protect the cable, preventing the connection ends of the cable with the male RF connector and the female RF connector from being in a bent state for a long time. When the connection end of the cable with the male RF connector is in a completely bent state, it is prone to cracking. The insertion block is elastically inserted into the inside of the slot by the elastic telescopic rod and presses against the inner wall of the slot, preventing the clamping frame from falling off the cable.

[0018] When the male RF connector and the female RF connector of the present invention are plugged together, the fixing ring will push the round hole rod and the round rod to move away from each other. The round rod will be inserted into the inside of the round hole rod as the fixing ring moves. After pushing the locking block into the inside of the groove, twist the round rod to rotate, so that the locking block can contact the bottom of the inner wall of the round hole rod. At this time, the round rod can move into the inside of the round hole rod as the male RF connector moves. After the male RF connector and the female RF connector are completely plugged together, twist the round rod to rotate inside the round hole rod. When the locking block corresponds to the inner wall of the jack, the elastic rod will push the stabilizing plate to move inside the groove. The stabilizing plate will push the inclined plate to move when moving. The locking block will limit the top of the inclined plate. When the inclined plate moves towards the bottom of the locking block, the locking block will move upward and insert into the inside of the jack. The round rod is clamped inside the round hole rod by the locking block to limit the fixing ring. The fixing ring squeezes and limits the male RF connector through the clamping frame, improving the stability after the male RF connector and the female RF connector are plugged together, and preventing the male RF connector and the female RF connector from falling off after being plugged together. The round rod inserted into the inside of the round hole rod can protect the male RF connector and the female RF connector, preventing the connection ends of the male RF connector and the female RF connector from breaking due to force.

[0019] When the male RF connector and the female RF connector of the present invention are plugged together, they are sleeved inside the rubber sleeve. The end of the rubber sleeve contacts the inner wall of the extrusion groove. The rubber sleeve is limited by the extrusion groove. When the fixing ring moves, it squeezes the rubber sleeve through the extrusion ring, improving the stability of the rubber sleeve sleeved on the surface of the male RF connector. The rubber sleeve is used to protect the connection ends of the male RF connector and the female RF connector. At the same time, the rubber sleeve can isolate dust outside the connection ends of the male RF connector and the female RF connector, preventing dust from entering the inside of the male RF connector.

[0020] Of course, it is not necessary for any product implementing the present invention to achieve all the above-mentioned advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0032] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0033] Please refer to Figures 1-8 As shown, the present invention is a radio frequency connector that prevents detachment, including a male radio frequency connector 1. The end of the male radio frequency connector 1 is inserted with a female radio frequency connector 2. Wires 3 are arranged at the ends of the male radio frequency connector 1 and the female radio frequency connector 2 that are far away from each other. Fixing components 4 are respectively arranged on the surfaces of the male radio frequency connector 1 and the female radio frequency connector 2;

[0034] The fixing component 4 includes a fixing ring 10. A limiting plate 11 is fixedly connected to the surface of the fixing ring 10. A clamping frame 12 is fixedly connected to the end of the limiting plate 11 away from the fixing ring 10. A slot 15 is formed in the inner wall of the clamping frame 12. An insertion block 16 is inserted into the inner wall of the slot 15. An elastic telescopic rod 17 is fixedly connected to the surface of the insertion block 16. An annular groove 13 is arranged inside the fixing ring 10. A sealing ring 14 is fixedly connected to the inner wall of the annular groove 13. A locking component 5 is arranged on the surface of the fixing ring 10. A sealing component 6 is arranged at the end of the fixing ring 10.

[0035] The number of the fixing rings 10 is two. After the male radio frequency connector 1 and the female radio frequency connector 2 are inserted into the inside of the fixing ring 10, the clamping frame 12 is inserted on the surface of the wire 3. The clamping frame 12 is located at the end of the wire 3 close to the male radio frequency connector 1. The wire 3 is protected by the clamping frame 12 to prevent the connection ends of the wire 3 with the male radio frequency connector 1 and the female radio frequency connector 2 from being in a bent state for a long time. The connection end of the wire 3 with the male radio frequency connector 1 is likely to crack when in a completely bent state. The insertion block 16 is inserted into the inside of the slot 15 by the elasticity of the elastic telescopic rod 17 and presses against the inner wall of the slot 15 to prevent the clamping frame 12 from detaching from the wire 3. The sealing rings 14 inside the two fixing rings 10 are respectively in contact with the surfaces of the male radio frequency connector 1 and the female radio frequency connector 2. The inner wall of the clamping frame 12 is in contact with the surface of the wire 3.

[0036] The number of the insertion blocks 16 is four. The four insertion blocks 16 are set into two groups, and the number of each group is two. The elastic telescopic rod 17 is located at the end of the two insertion blocks 16 close to each other. The clamping frame 12 is located at the end of the wire 3 close to the male radio frequency connector 1.

[0037] The locking component 5 includes a round-hole rod 21. A round rod 20 is slidably connected to the inner wall of the round-hole rod 21. A mounting plate 29 is fixedly connected to the surface of the fixed ring 10. One end of the round-hole rod 21 away from the round rod 20 is fixedly connected to the mounting plate 29. One end of the round rod 20 away from the round-hole rod 21 is rotatably connected to the surface of the mounting plate 29. A jack 22 is formed on the surface of the round-hole rod 21. A groove 23 is formed on the surface of the round rod 20. An elastic rod 26 is fixedly connected to the inner wall of the groove 23. One end of the elastic rod 26 away from the groove 23 is fixedly connected to a stabilizing plate 25. One end of the stabilizing plate 25 away from the elastic rod 26 is hinged to an inclined plate 28. A locking block 24 is hinged to the top of the inclined plate 28. A telescopic rod 27 is fixedly connected to the bottom of the locking block 24. The bottom of the telescopic rod 27 is fixedly connected to the bottom of the inner wall of the groove 23.

[0038] The round-hole rod 21 and the round rod 20 are located at one end where the two fixed rings 10 are close to each other. When the RF connection male head 1 and the RF connection female head 2 of the present invention are plugged together, the fixed ring 10 will push the round-hole rod 21 and the round rod 20 to move away from each other. The round rod 20 will be inserted into the round-hole rod 21 as the fixed ring 10 moves. After the locking block 24 is pushed into the groove 23, the round rod 20 is twisted to rotate, so that the locking block 24 can contact the bottom of the inner wall of the round-hole rod 21. At this time, the round rod 20 can move into the round-hole rod 21 as the RF connection male head 1 moves. After the RF connection male head 1 and the RF connection female head 2 are plugged together, one end of the round rod 20 close to the mounting plate 29 extends to the outer end of the round-hole rod 21.

[0039] A plurality of jacks 22 are formed at the top of the round-hole rod 21. The round rod 20 is twisted to rotate inside the round-hole rod 21. When the locking block 24 corresponds to the inner wall of the jack 22, the elastic rod 26 will push the stabilizing plate 25 to move inside the groove 23. The stabilizing plate 25 pushes the inclined plate 28 to move when moving. The locking block 24 limits the top of the inclined plate 28. When the inclined plate 28 moves towards the bottom of the locking block 24, the locking block 24 will move upward and be inserted into the jack 22. The round rod 20 is clamped inside the round-hole rod 21 by the locking block 24 to limit the fixed ring 10. Two elastic rods 26 are arranged inside the groove 23, and the two elastic rods 26 are symmetrically arranged with the locking block 24 as the center.

[0040] The surface of the stabilizing plate 25 is slidably connected to the inner wall of the groove 23. The fixed ring 10 squeezes and limits the RF connection male head 1 through the clamping frame 12, improving the stability after the RF connection male head 1 and the RF connection female head 2 are plugged together, and avoiding the situation of the RF connection male head 1 and the RF connection female head 2 falling off after being plugged together. The round rod 20 inserted into the round-hole rod 21 can protect the RF connection male head 1 and the RF connection female head 2. One end of the inclined plate 28 away from the stabilizing plate 25 is inclined upward. The surface of the locking block 24 contacts the inner wall of the jack 22.

[0041] The sealing member 6 includes an extrusion ring 30. The surface of the extrusion ring 30 is fixedly connected to the end of the fixed ring 10. An extrusion groove 31 is formed at one end of the extrusion ring 30 away from the fixed ring 10, and a rubber sleeve 32 is inserted into the inner wall of the extrusion groove 31.

[0042] The number of the extrusion rings 30 is two. When the male RF connector 1 of the present invention is inserted into the female RF connector 2, the extrusion rings 30 are sleeved inside the rubber sleeve 32. The end of the rubber sleeve 32 contacts the inner wall of the extrusion groove 31. The rubber sleeve 32 is limited by the extrusion groove 31. When the fixed ring 10 moves, the rubber sleeve 32 is extruded by the extrusion ring 30, so as to improve the stability after the rubber sleeve 32 is sleeved on the surface of the male RF connector 1. The connection end of the male RF connector 1 and the female RF connector 2 is protected by the rubber sleeve 32. At the same time, the rubber sleeve 32 can isolate dust outside the connection end of the male RF connector 1 and the female RF connector 2, avoiding dust from entering the inside of the male RF connector 1. The two extrusion rings 30 are symmetrically arranged with the rubber sleeve 32 as the center. The rubber sleeve 32 is located at one end where the male RF connector 1 and the female RF connector 2 are close to each other. The two extrusion rings 30 are located at one end where the two fixed rings 10 are close to each other.

[0043] During use, after inserting the male RF connector 1 and the female RF connector 2 into the inside of the fixing ring 10, insert the card holder 12 on the surface of the cable 3. The card holder 12 is located at one end of the cable 3 close to the male RF connector 1, and the cable 3 is protected by the card holder 12 to prevent the connection ends of the cable 3 with the male RF connector 1 and the female RF connector 2 from being in a bent state for a long time. The connection end of the cable 3 with the male RF connector 1 being in a completely bent state is prone to cracking. The insertion block 16 is inserted into the inside of the slot 15 by the elasticity of the elastic telescopic rod 17 and presses against the inner wall of the slot 15 to prevent the card holder 12 from falling off the cable 3. When the male RF connector 1 and the female RF connector 2 are plugged together, the fixing ring 10 will push the round hole rod 21 and the round rod 20 to move away from each other. The round rod 20 will be inserted into the inside of the round hole rod 21 as the fixing ring 10 moves. After pushing the locking block 24 into the inside of the groove 23, twist the round rod 20 to rotate so that the locking block 24 can contact the bottom of the inner wall of the round hole rod 21. At this time, the round rod 20 can move into the inside of the round hole rod 21 as the male RF connector 1 moves. After the male RF connector 1 and the female RF connector 2 are plugged together, twist the round rod 20 to rotate inside the round hole rod 21. When the locking block 24 corresponds to the inner wall of the jack 22, the elastic rod 26 will push the stabilizing plate 25 to move inside the groove 23. The stabilizing plate 25 will push the inclined plate 28 to move when it moves. The locking block 24 will limit the top of the inclined plate 28. When the inclined plate 28 moves towards the bottom of the locking block 24, the locking block 24 will move upward and be inserted into the inside of the jack 22. The round rod 20 is locked inside the round hole rod 21 by the locking block 24 to limit the fixing ring 10. The fixing ring 10 limits the male RF connector 1 by pressing through the card holder 12, improving the stability after the male RF connector 1 and the female RF connector 2 are plugged together and preventing the male RF connector 1 and the female RF connector 2 from falling off after being plugged together. The round rod 20 being inserted into the inside of the round hole rod 21 can protect the male RF connector 1 and the female RF connector 2 from the connection ends being broken due to force. When the male RF connector 1 and the female RF connector 2 are plugged together, put them into the inside of the rubber sleeve 32. The end of the rubber sleeve 32 contacts the inner wall of the extrusion groove 31, and the rubber sleeve 32 is limited by the extrusion groove 31. When the fixing ring 10 moves, it squeezes the rubber sleeve 32 through the extrusion ring 30, improving the stability of the rubber sleeve 32 after being sleeved on the surface of the male RF connector 1. The connection ends of the male RF connector 1 and the female RF connector 2 are protected by the rubber sleeve 32. At the same time, the rubber sleeve 32 can isolate dust outside the connection ends of the male RF connector 1 and the female RF connector 2, preventing dust from entering the inside of the male RF connector 1.
