[0001] The utility model relates to the technical field of radio frequency connectors, in particular to a miniaturized low-profile radio frequency connector. Background Art

[0002] With the rapid development of modern electronic technology, RF connectors are increasingly used in wireless communications, radar, satellite navigation and other fields. However, traditional RF connectors often have the problems of large size and high profile. Therefore, it is necessary to set up a miniaturized low-profile RF connector to meet market demand. However, the existing devices still have certain use defects when in use, such as:

[0003] During the use of the device, traditional RF connectors are mostly connected by threads, and the threads may be misaligned, causing the pin to be unable to align with the socket, causing damage to the pin and the socket, thereby reducing the service life of the RF connector. After long-term use, the threaded connection will cause sliding due to vibration, resulting in a loose connection between the pin and the socket, which in turn causes unstable signal transmission. Utility Model Content

[0004] The utility model aims to solve the above-mentioned problem and proposes a miniaturized low-profile radio frequency connector, which improves the problem of unstable connection of the existing miniaturized low-profile radio frequency connector.

[0005] A miniaturized low-profile radio frequency connector comprises a first shell, a threaded shell and a connecting shell: a side of the first shell is provided with a threaded shell, the threaded shell is connected to the first shell, a side of the threaded shell is provided with a connecting shell, a side of the first shell is provided with a positioning structure, and a side of the positioning structure is provided with a snap-fit ​​structure;

[0006] The positioning structure comprises an inserting plate and a fixing block. The fixing block is arranged on the side of the connecting shell, and the inserting plate is arranged inside the fixing block. The inserting plate is embedded inside the fixing block.

[0007] Preferably, a sliding block is provided on the side of the first shell, the sliding block is slidably connected to the first shell, and one end of the plug board is connected to the sliding block.

[0008] Preferably, a pin is provided inside the first shell, a socket is provided inside the threaded shell, and a sealing ring is provided at the top end of the threaded shell.

[0009] Preferably, a fixing ring is provided on the side of the first shell, the side of the fixing ring is connected to the sliding block, and a connecting box is provided on the side of the connecting shell.

[0010] Preferably, the locking structure includes a first spring, a second spring, a locking block and a limiting block, the second spring is arranged inside the plug plate, the locking block is arranged at the top of the second spring, the limiting block is arranged on the side of the locking block, and the first spring is arranged on the side of the limiting block.

[0011] Preferably, the limiting block is slidably connected to the plug plate, and the engaging block is arranged in a trapezoidal shape.

[0012] Preferably, a pushing block is arranged on the side of the fixed block, a movable block is arranged on the side of the pushing block, a return spring is arranged on the side of the movable block, and the movable block is slidably connected to the fixed block.

[0013] The beneficial effects of the utility model are:

[0014] 1. Through the setting of the fixing block and the plug plate, the first shell is first screwed to the surface of the threaded shell. If the thread is not misaligned, the plug plate will be inserted into the inside of the fixing block, so as to determine that the pin has not been offset, so that the pin will not cause damage to the socket. When the thread is offset, the plug plate cannot be inserted into the inside of the fixing block, and the plug plate is pressed against the side of the fixing block to prevent the first shell from moving forward further and causing damage to the pin to the socket. In this way, the thread is prevented from being offset during installation, causing damage to the pin and the socket, thereby reducing the service life of the device;

[0015] 2. By means of the first spring, the second spring, the engaging block and the pushing block, when the plug-in board is inserted into the interior of the fixed block, the inner wall of the fixed block presses the engaging block into the interior of the plug-in board. When the engaging block moves to the position of the pushing block, the engaging block is pushed out by the resilience of the first spring and the second spring, so that the engaging block fits with the pushing block, and the plug-in board is fixed by contacting one side of the engaging block with one side of the fixed block to prevent the plug-in board from falling out of the interior of the fixed block, thereby fixing the device and preventing the thread from sliding due to vibration during long-term use, so that the connection between the pin and the socket is not tight enough.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] When implementing: Figure 1-4 As shown, a miniaturized low-profile radio frequency connector includes a first shell 1, a threaded shell 2 and a connecting shell 3: the side of the first shell 1 is provided with the threaded shell 2, the threaded shell 2 is connected to the first shell 1, the side of the threaded shell 2 is provided with the connecting shell 3, the side of the first shell 1 is provided with a positioning structure 19, and the side of the positioning structure 19 is provided with a snap-fit ​​structure 20;

[0023] The positioning structure 19 includes an insert plate 9 and a fixing block 11. The fixing block 11 is disposed on the side of the connecting shell 3. The insert plate 9 is disposed inside the fixing block 11. The insert plate 9 is embedded inside the fixing block 11.

[0024] When the device is in use, the first shell 1 is first screwed onto the surface of the threaded shell 2 to align the plug plate 9 with the fixing block 11. At this time, when the thread is not misaligned, the plug plate 9 will be normally inserted into the interior of the fixing block 11, so that the pin 5 will not cause damage to the socket 10. When the thread is offset, the first shell 1 will be offset. At this time, the plug plate 9 will press against the side of the fixing block 11 and cannot normally enter the empty groove opened in the fixing block 11, so that the pin 5 cannot touch the socket 10 and will never cause damage to the socket 10.

[0025] A sliding block 7 is provided on the side of the first housing 1, the sliding block 7 is slidably connected to the first housing 1, and one end of the plug board 9 is connected to the sliding block 7;

[0026] When the device is in use, the sliding block 7 is slidably connected to the first housing 1 , and the sliding block 7 is fixed to the fixing ring 6 , so when the first housing 1 rotates to the surface of the threaded housing 2 , the sliding block 7 will not be driven to rotate.

[0027] A pin 5 is disposed inside the first shell 1, a plug hole 10 is disposed inside the threaded shell 2, and a sealing ring 8 is disposed at the top of the threaded shell 2;

[0028] When the device is connected, the first shell 1 is screwed onto the surface of the threaded shell 2 to insert the pin 5 into the inside of the jack 10, so as to connect the RF connector. By setting the sealing ring 8, when the RF connector is in a relatively humid place, the moisture in the pin 5 and the jack 10 can be sealed to prevent the pin 5 and the jack 10 conductors from being corroded.

[0029] A fixing ring 6 is disposed on the side of the first housing 1, and a side of the fixing ring 6 is connected to a sliding block 7. A connecting box 4 is disposed on the side of the connecting housing 3.

[0030] The clamping structure 20 includes a first spring 12, a second spring 13, a clamping block 14 and a limiting block 15. The second spring 13 is arranged inside the plug board 9, the clamping block 14 is arranged at the top of the second spring 13, the limiting block 15 is arranged on the side of the clamping block 14, and the first spring 12 is arranged on the side of the limiting block 15;

[0031] When the device is in use, when the plug board 9 is successfully inserted into the fixing block 11, the inner wall of the fixing block 11 presses the locking block 14 into the inside of the plug board 9. At this time, when the top end of the plug board 9 is in contact with the fixing block 11, the locking block 14 is pushed out into the inside of the fixing block 11 by the resilience of the first spring 12 and the second spring 13. The plug board 9 is fixed by contacting one side of the locking block 14 with one side of the fixing block 11 to prevent the plug board 9 from falling out of the fixing block 11, thereby fixing the connector of the RF connector.

[0032] The limiting block 15 is slidably connected to the plug plate 9, and the engaging block 14 is arranged in a trapezoidal shape.

[0033] A push block 16 is disposed on the side of the fixed block 11, a movable block 17 is disposed on the side of the push block 16, a return spring 18 is disposed on the side of the movable block 17, and the movable block 17 is slidably connected to the fixed block 11;

[0034] When the device is in use, the device is first fixed by the snap-fit ​​structure 20. When the device needs to be disassembled, the push block 16 is pressed to drive the movable block 17 to move in the direction of the snap-fit ​​block 14, and the push block 16 presses the snap-fit ​​block 14 back into the inside of the plug plate 9. Then, the first shell 1 is rotated to disengage from the surface of the threaded shell 2, so that the plug plate 9 is pulled out from the inside of the fixed block 11.

[0035] When the utility model is in use, when the RF connector needs to be connected, firstly, the first shell 1 is screwed to the surface of the threaded shell 2, and the plug-in plate 9 is aligned with the empty groove of the fixing block 11. At this time, the first shell 1 is continued to be rotated so that the first shell 1 drives the plug-in plate 9 to enter the interior of the fixing block 11. At this time, the inner wall of the fixing block 11 presses the locking block 14 into the interior of the plug-in plate 9. Subsequently, when the first shell 1 is completely screwed to the surface of the threaded shell 2, the pin 5 is inserted into the interior of the socket 10, and the top of the plug-in plate 9 is fitted with the inner wall of the fixing block 11. At this time, the locking block 14 is popped out and fitted with the fixing block 11 through the rebound force of the first spring 12 and the second spring 13, so as to lock the connection of the RF connector to prevent the thread from sliding due to vibration caused by long-term use, resulting in a gap between the pin 5 and the socket 10, which affects the signal transmission.

[0036] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
