It can establish a reliable signal transmission channel between different RF devices to ensure that the RF signal is transmitted in a low-loss, high-stability manner. The RF connector joint is the connecting port and is the key part of the RF connector that directly contacts the cable or other devices for physical contact and signal transmission. The quality of the joint directly affects the performance of the entire RF connector. For example, the dimensional accuracy and contact reliability of the joint play a vital role in the signal transmission quality.

[0003] When the RF connector is in use, the center parts of the two ends of the connector are respectively plugged and fixed with the antenna of the external device and the RF connector socket, and threaded connection blocks are arranged on the outside of the two ends. The stability of the threaded connection blocks can improve the fixing effect of the connector. However, in some existing technologies, when the RF connector is affected by external force collision, it may still fall off due to excessive force, and the center of the connector may rotate and separate from the installation part, causing overall damage to the connector and affecting normal use. Therefore, an RF connector is proposed to address the above problems. Summary of the invention

When the mounting block is threadedly connected to the outside of the RF connector socket, the friction between the mounting block and the abutting block can be increased, thereby improving the fixing effect between the mounting block and the first joint, so that the two cannot rotate separately, thereby avoiding the problem that the mounting block and the first joint may be damaged by rotation due to external force after installation;

[0029] The above scheme is adopted: the first joint 1, the second connection block 6, the first connection block 3 and the second joint 5 constitute the RF connector joint body, the first joint 1 can be connected to the RF connector, and the second joint 5 can be connected to the transmission device antenna, which is the prior art; the mounting block 201 in the connecting mechanism 2 is provided with an internal thread, through which the joint body can be installed on the outside of the RF connector, and the second joint 5 is provided with an external thread, which can be threadedly connected with the transmission device antenna for fixing; the connecting mechanism 2 can improve the fixing effect between the mounting block 201 and the first joint 1 after the mounting block 201 is fixed, so as to prevent the first joint 1 from rotating inside the mounting block 201 and affecting The protective mechanism 4 can protect the connection between the second connector 5 and the antenna of the transmission device, and can improve the fixation of the antenna of the transmission device to prevent it from falling off and affecting normal use; the abutment block 204 is made of rubber material, which can be moved to abut against the inner wall thread of the mounting block 201, and produce a certain deformation under force, thereby increasing the friction between the mounting block 201 and the first connector 1, and when installing the mounting block 201, the abutment block 204 can be received in the inner wall of the second connecting block 6, which will not affect the installation of the mounting block 201 through the internal thread rotation; the abutment block 204 and the connecting rod 203 are provided with four groups, and the mounting block 201 is fixed from four directions.

[0030] like Figures 3 to 5 As shown, the mounting block 201 is rotatably connected to the outer wall of the second connecting block 6, and the connecting rod 203 contacts the inner wall of the inclined groove 205; the abutment block 204 is slidably connected to the inner wall of the second connecting block 6, and the fixed block 206 passes through one side outer wall of the second connecting block 6; one end of the connecting spring 207 is fixedly connected to the outer wall of the movable plate 208, and the other end of the connecting spring 207 is fixedly connected to the inner wall of the fixed block 206; the movable plate 208 and the clamping block 209 are both slidably connected to the inner wall of the fixed block 206, and the clamping block 209 is clamped in the clamping groove 210.

[0031] The above scheme is adopted: two groups of card slots 210 are provided, and the rotating block 202 can be limited and fixed by engaging the card blocks 209 with the card slots 210. The two groups of card slots 210 can rotate the rotating block 202 to two positions for fixing. Two groups of card blocks 209 are provided on the movable plate 208, one group of card blocks 209 is always outside the second connecting block 6, and the other group is engaged with the card slots 210. By pressing the card blocks 209 on the outside, the movable plate 208 and the other group of card blocks 209 can be driven to move synchronously. The connecting spring 207 is forced to contract, so that the group of card blocks 209 can be disengaged from the card slots 210, and the limit of the rotating block 202 is released to rotate it; when the rotating block 202 rotates, the inner part of the inclined slot 205 The wall squeezes the connecting rod 203 to move the connecting rod 203. Since the connecting rod 203 and the abutment block 204 are both slidably connected to the inner wall of the second connecting block 6, the inner wall of the second connecting block 6 guides the two, so that when the rotating block 202 rotates, the abutment block 204 can be driven to move to the middle or both sides at the same time, so that the abutment block 204 can contact the internal thread or be retracted into the second connecting block 6; when the rotating block 202 is rotated to a suitable position, the elastic force of the connecting spring 207 can drive the movable plate 208 and the two groups of clamping blocks 209 to pop out at the same time, and one group of clamping blocks 209 is clamped with the clamping groove 210, so that the rotating block 202 can be limited, so that the positions of the four groups of abutment blocks 204 are fixed to maintain the fixing effect.

[0032] like Figure 6 and Figure 7 As shown, the protective mechanism 4 includes a protective shell 401, the outer wall of the protective shell 401 is fixedly connected with a protrusion 405, the inner wall of the protrusion 405 is elastically connected with an insertion block 407 through a telescopic spring 406, the outer wall of the first connecting block 3 is hinged with a moving rod 403 through a hinge rod 402, the inner wall of the protective shell 401 is slidably connected with a clamping block 404, and the outer wall of the first connecting block 3 is provided with a slot 408; the protective shell 401 is slidably connected to the outer wall of the first connecting block 3, and the insertion block 407 penetrates the outer wall of the protrusion 405; one end of the telescopic spring 406 is fixedly connected to the outer wall of the insertion block 407, and the other end of the telescopic spring 406 is fixedly connected to the inner wall of the protrusion 405; the insertion block 407 is slidably connected to the inner wall of the protrusion 405, and the insertion block 407 is clamped with the slot 408; one end of the hinged rod 402 is hinged to the moving rod 403, and the other end of the hinged rod 402 is hinged to the outer wall of the first connecting block 3.

[0033] With the above solution, the second connector 5 and the external device antenna can be protected by the protective mechanism 4 to prevent them from falling off due to external forces, which may cause the external device antenna to be unable to be used normally. The external device antenna can be sleeved on the second connector 5 and rotated, and fixed by the thread of the second connector 5. After the fixing is completed, the protective shell 401 can be moved to drive the four groups of clamping blocks 404 to move toward the middle at the same time, contact the outer wall of the antenna and clamp it, so as to improve the fixing effect. Figure 6, Figure 7 As shown, when the protective shell 401 moves to the right, the clamping block 404 can be driven to move synchronously with the moving rod 403, and the hinge rod 402 can be pulled to flip, so that the four groups of clamping blocks 404 can move toward the middle at the same time; and when the protective shell 401 is moved to the left, the clamping block 404 can be driven to move outward at the same time, so that the antenna can be removed from the second connector 5; when the protective shell 401 needs to be moved, the plug-in block 407 can be pulled upward, the telescopic spring 406 is forced to shrink, and the plug-in block 407 is out of contact with the slot 408, so that the protective shell 401 can be released from the limit and moved; and when the protective shell 401 is moved to a suitable position, the telescopic spring 406 causes the plug-in block 407 to pop out and engage with the slot 408 due to its own elastic force, so that the protective shell 401 can be fixed, which is more convenient.

[0034] The working principle and use process of the present invention:

[0035] The first connector 1, the second connection block 6, the first connection block 3 and the second connector 5 constitute the main body of the RF connector connector. The first connector 1 can be connected to the RF connector and is threadedly connected to the RF connector socket through the internal thread of the mounting block 201 to improve the fixing effect, and the second connector 5 at the other end can be threadedly connected to the transmission device antenna through its external thread. The above are all existing technologies well known to professionals in this field; when the rotating mounting block 201 is connected to the socket, the abutment block 204 is in the inner wall of the second connection block 6, and will not hinder the threaded installation process of the mounting block 201; at this time, the clamping block 209 in the fixing block 206 on the outer wall of the rotating block 202 is clamped with a group of clamping grooves 210 directly below, and the rotating block 202 is limited to the initial position, so that the inclined groove 205 and the connecting rod 203 are in a relatively stable state, thereby ensuring that the abutment block 204 is in the initial storage position.

[0036] When the mounting block 201 is installed outside the RF connector, the connection mechanism 2 can be used to improve the fixing effect between it and the first connector 1 to prevent the first connector 1 and the mounting block 201 from rotating and causing damage; by pressing the lower group of blocks 209 outside the fixed block 206, the movable plate 208 is driven to move toward the inner wall of the fixed block 206, so that the connecting spring 207 is forced to contract, and then the upper group of blocks 209 engaged with the slot 210 are disengaged from the slot 210, thereby releasing the limit of the rotating block 202.

[0037] Then rotate the rotating block 202. During the rotation of the rotating block 202, the inner walls of the multiple groups of inclined grooves 205 opened on its outer wall will squeeze the corresponding connecting rod 203. Since the connecting rod 203 and the abutment block 204 are both slidably connected to the inner wall of the second connecting block 6, under the guidance of the inner wall of the second connecting block 6, the connecting rod 203 will drive the abutment block 204 to move around at the same time. The abutment block 204 is made of rubber material. When it moves to abut against the inner wall thread of the mounting block 201, it will be subjected to force and produce a certain deformation, thereby increasing the friction between the mounting block 201 and the first joint 1, and improving the fixing effect.

[0038] When the rotating block 202 rotates to a suitable position, the elastic force of the connecting spring 207 drives the movable plate 208 and the two groups of blocks 209 to pop outward at the same time, and the upper group of blocks 209 is engaged with the other group of inclined slots 210, and the rotating block 202 is limited again, so that the positions of the four groups of abutment blocks 204 are fixed, maintaining the fixing effect between the mounting block 201 and the first joint 1, so as to avoid the problem of possible rotation between the first joint 1 and the mounting block 201 after installation and causing damage.

[0039] When the second connector 5 needs to be connected to the transmission device antenna, the external device antenna is first sleeved on the second connector 5. At this time, the protective shell 401 of the protective mechanism 4 is in the initial position, and the second connector 5 is outside the protective shell 401. The plug block 407 is engaged with a group of slots 408 under the action of the telescopic spring 406 to fix the protective shell 401 to the outer wall of the first connecting block 3; after the external device antenna is fixed through the external thread of the second connector 5, it is necessary to protect its connection and further improve the fixing effect, such as Figure 6 , Figure 7 As shown, the protective shell 401 can be moved to the right side. When the protective shell 401 moves, the clamping block 404 and the moving rod 403 will be driven to move synchronously. Since one end of the hinged rod 402 is hinged to the moving rod 403, and the other end is hinged to the outer wall of the first connecting block 3, when the protective shell 401 moves to the right, the hinged rod 402 will be pulled to flip toward the middle. Under the guidance of the inner wall of the protective shell 401, the four groups of clamping blocks 404 move toward the middle at the same time, contact and clamp the outer wall of the antenna. The clamping blocks 404 are also made of rubber material and contact the outer wall of the antenna. After the touch, a certain deformation will also be produced, and it will fit tightly with the outer wall of the antenna, which can improve the fixing effect of the antenna; and in this state, the protective shell 401 will cover the second connector 5, and protect the connection between the second connector 5 and the antenna, which can prevent it from falling off due to external force collision, thereby ensuring the normal use of the device; at this time, the telescopic spring 406 causes the plug-in block 407 to pop out downward due to its own elastic force, and the plug-in block 407 corresponds to the position of another group of slots 408, and is engaged with the group of slots 408, so that the protective shell 401 can be fixed.

[0040] When the antenna needs to be disassembled, the protective shell 401 can be moved to the left first. During the movement of the protective shell 401 to the left, the clamping block 404 is driven to move outward at the same time to release the clamping of the antenna, and the antenna can be rotated to be removed from the second connector 5; when the protective shell 401 needs to be moved, the plugging block 407 can be pulled upward, the telescopic spring 406 is forced to shrink, and the plugging block 407 is out of contact with the slot 408, so that the limit of the protective shell 401 can be released, and then the protective shell 401 can be moved to a suitable position, so that the plugging block 407 can be moved again. Then, the protective shell 401 is fixed in the initial position by engaging with another group of slots 408; then, the lower group of card blocks 209 can be pressed to drive the upper group of card blocks 209 to disengage from the card slots 210, thereby releasing the limit of the rotating block 202, and rotating the rotating block 202 in the opposite direction, thereby driving the four groups of connecting rods 203 and the abutting block 204 to move inward at the same time and disengage from the internal thread of the mounting block 201, thereby releasing the fixation of the mounting block 201, and rotating the mounting block 201 to disengage it from the RF connector socket, and then removing the device.
