Description

Technical Field

[0001] The present invention relates to the technical field of connectors, and particularly to a radio frequency coaxial connector plug and socket. Background Art

[0002] A radio frequency coaxial connector is a type of microwave component, which is an electrical component used to connect various microwave circuits. It can be used for the output and input ports of microwave instruments and equipment, the connection between various radio frequency modules, and the connection between a transmitting device and an antenna, etc. A radio frequency coaxial connector consists of a plug and a socket. Usually, the active connection part with a locking device is called a plug, and the passive connection part is called a socket. The traditional connection methods of radio frequency coaxial connectors include: threaded connection, bayonet connection, plug-in connection, etc. However, these connection methods all have problems such as vibration failure, discontinuous transmission characteristics, large installation spacing, and complex connection operations.

[0003] For this reason, the Chinese invention patent with the publication number CN101958494B provides a coaxial connector, which realizes unlocking by operating an unlocking sleeve. However, during the use process, the applicant found that the elastic locking mechanism in this coaxial connector is prone to losing elasticity, resulting in an insecure connection between the plug and the socket of the coaxial connector. Therefore, the effective connection times of this coaxial connector are relatively low; in addition, if this coaxial connector is installed in a narrow space, when it is necessary to remove the plug of the coaxial connector, due to space limitations, although the human hand can touch the coaxial connector, it is difficult to apply enough force to push the unlocking sleeve to slide. Therefore, there is a problem of difficult unlocking in this case. Summary of the Invention

[0045] Technologies, methods, and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and devices should be regarded as part of the specification.

[0046] SeeFigures 1-16 As shown in the figure, the present invention provides a radio frequency coaxial connector plug 100, which includes a first outer conductor 1, a second outer conductor 2, a first insulator 3, a plug inner conductor 4, and a connection mechanism for snap connection with a socket.

[0047] See Figure 5 As shown in the figure, a first through hole 101 is provided on the first outer conductor 1. The first through hole 101 is a circular hole and penetrates through both ends of the first outer conductor 1.

[0048] See Figure 6 As shown in the figure, the second outer conductor 2 is composed of an integrally formed connecting portion 203 and a plugging portion 202. The connecting portion 203 is located at the right end of the second outer conductor 2, and the plugging portion 202 is located at the left end of the second outer conductor 2. Both the connecting portion 203 and the plugging portion 202 are cylindrical, and the outer diameter of the connecting portion 203 is larger than the outer diameter of the plugging portion 202. An external thread for connecting with the first outer conductor 1 is provided on the connecting portion 203. Four cutting grooves 204 are provided on the plugging portion 202. The extending direction of the cutting grooves 204 is parallel to the axis of the second through hole 201. The second through hole 201 penetrates through both the connecting portion 203 and the plugging portion 202 at the same time. See Figure 3 As shown in the figure, the right end of the second outer conductor 2 is threadedly connected to the left end of the first outer conductor 1. After the second outer conductor 2 is connected to the first outer conductor 1, the first through hole 101 of the first outer conductor 1 and the second through hole 201 of the second outer conductor 2 are coaxial.

[0049] See Figure 3 As shown in the figure, the first insulator 3 is arranged in the first through hole 101 and fixedly connected to the first outer conductor 1; the plug inner conductor 4 is coaxially arranged with the first outer conductor 1. The plug inner conductor 4 penetrates through the first insulator 3. One end of the plug inner conductor 4 extends into the first through hole 101, and the other end of the plug inner conductor 4 extends into the second through hole 201. In a specific implementation, the first insulator 3 can be made of insulating materials such as glass or ceramic. The first insulator 3 is formed in the first through hole 101 of the first outer conductor 1 by a sintering process. Before sintering the first insulator 3, first place the plug inner conductor 4 into the first through hole 101 and the second through hole 201 and make the plug inner conductor 4 coaxial with the first through hole 101; after the first insulator 3 is sintered and formed, the outer wall of the first insulator 3 is in close contact with the inner wall of the first outer conductor 1, and the middle part of the plug inner conductor 4 is fixed in the first insulator 3.

[0050] The aforementioned connection mechanism includes a mounting ring 5, a rotating shell 6, a groove plate 7, a locking block 8, a lever 9, and a first elastic member 22.

[0051] For the convenience of processing and assembly, one end of the mounting ring 5 is detachably connected to the first outer conductor 1. As shown in Fig. 7, a third through hole 501 coaxial with the second through hole 201 is provided on the mounting ring 5. The third through hole 501 is a circular hole and its diameter is larger than the outer diameter of the insertion part 202 of the second outer conductor 2. As shown in Figure 3 After the mounting ring 5 is connected to the first outer conductor 1, as shown, the second outer conductor 2 is located in the third through hole 501, and there is a first gap 15 between the second outer conductor 2 and the mounting ring 5. The aforementioned first gap 15 can be inserted by the third outer conductor 18 on the connector socket.

[0052] The rotating shell 6 is a hollow cylindrical shape. As shown in Figure 3 After the rotating shell 6 is sleeved on the outside of the mounting ring 5, when the rotating shell 6 is manually rotated, the rotating shell 6 can rotate around the axis of the second through hole 201.

[0053] As shown in Figure 3 After the slot plate 7 is provided in the rotating shell 6 and hollowed out in the middle, the slot plate 7 rotates synchronously with the rotating shell 6. The mounting ring 5 is located between the slot plate 7 and the first outer conductor 1. The hollow structure in the middle of the slot plate 7 can allow the third outer conductor 18 on the RF coaxial connector socket 200 to pass through. As shown in Figure 10 As shown, an arc-shaped track groove 705 is provided on the slot plate 7. The track groove 705 is close to the edge of the slot plate 7. The track groove 705 has a first end 7051 and a second end 7052. The first end 7051 is closer to the center of the slot plate 7 than the second end 7052.

[0054] The locking block 8 is connected to one end of the mounting ring 5 away from the first outer conductor 1, and the locking block 8 can slide along the radial direction of the mounting ring 5. The number of the locking blocks 8 can be one or more than two. When the number of the locking blocks 8 is more than two, the locking blocks 8 are distributed in an annular array around the center of the left end face of the second outer conductor 2. A lever 9 is provided on each locking block 8. One end of the lever 9 is fixedly connected to the locking block 8, and the other end of the lever 9 is inserted into the track groove 705 of the slot plate 7 and can slide in the track groove 705. When the lever 9 is located at the first end 7051 of the track groove 705, at least part of the locking block 8 is inserted into the first gap 15. One end of the first elastic member 22 is connected to the slot plate 7, and the other end of the first elastic member 22 is connected to the mounting ring 5. The first elastic member 22 applies an elastic force to keep the lever 9 at the first end 7051 of the track groove 705.

[0055] In the present invention, the first elastic member 22 adopts a tension spring. As shown in Figure 2 When the first elastic member 22 is in the shortest state, as shown, the first elastic member 22 pulls the slot plate 7 and keeps the lever 9 at the first end 7051 of the track groove 705. At this time, the locking block 8 is located at the locking position, and a part of the locking block 8 is inserted into the first gap 15 and can be used to insert into the locking hole 1802 on the RF coaxial connector socket 200. As shown in Figure 2As shown, rotating the rotating shell 6 counterclockwise can move the locking block 8 from the locked position to the unlocked position, realizing the unlocking operation of the RF coaxial connector plug 100; when the rotating shell 6 is rotated counterclockwise, the rotating shell 6 drives the groove plate 7 to rotate synchronously. During this process, the lever 9 slides from the first end 7051 to the second end 7052 of the track groove 705, and the lever 9 drives the locking block 8 to gradually move away from the center of the second outer conductor 2. At the same time, the rotating groove plate 7 stretches the first elastic member 22; after removing the torsion applied to the rotating shell 6, the pulling force provided by the first elastic member 22 will drive the groove plate 7 and the rotating shell 6 to rotate clockwise, so that the locking block 8 returns to the locked position again.

[0056] In the present invention, the RF coaxial connector plug 100 further includes an end cap 10. A fourth through hole 1001 is provided at the center of the end cap 10. The size of the fourth through hole 1001 should be suitable for the third outer conductor 18 on the RF coaxial connector socket 200 to pass through. The groove plate 7 is located between the end cap 10 and the mounting ring 5, and one end of the end cap 10 is connected to the rotating shell 6. By providing the end cap 10, key components such as the locking block 8 and the first elastic member 22 can be protected, which is beneficial to extending the service life of the RF coaxial connector plug 100. Moreover, the provided end cap 10 can also make the appearance of the RF coaxial connector plug 100 more concise and beautiful.

[0057] As shown in Fig. 7, a fifth through hole 502 communicating with the third through hole 501 is provided on the outer wall of the mounting ring 5. The fifth through hole 502 is a circular hole and the number is equal to that of the locking blocks 8. A sliding groove 503 communicating with the fifth through hole 502 is provided on the end surface of the mounting ring 5 away from the first outer conductor 1. The extending direction of the sliding groove 503 is the same as that of the fifth through hole 502. The locking block 8 is located in the fifth through hole 502 and can slide in the fifth through hole 502. The lever 9 sequentially passes through the track groove 705, the sliding groove 503 and is connected to the locking block 8. In a specific implementation, the axis of the fifth through hole 502 is perpendicular to and coplanar with the axis of the third through hole 501. By drilling the fifth through hole 502 on the outer wall of the mounting ring 5, the installation of the locking block 8 can be realized. The processing and assembly processes are very simple, and it can also ensure that the locking block 8 moves along the radial direction of the second outer conductor 2.

[0058] See Figure 4 As shown, a plug 11 is provided at the outer end of the fifth through hole 502. For the convenience of disassembly, the plug 11 is threadedly connected to the second outer conductor 2. See Figures 11 to 13bAs shown, the lock block 8 includes a lock sleeve 801 and a lock tongue 802; the lock sleeve 801 is cylindrical, the lock sleeve 801 is located in the fifth through hole 502 and can slide in the fifth through hole 502. One end of the lock sleeve 801 adjacent to the plug 11 is provided with a first channel 8011, and the other end of the lock sleeve 801 is provided with a second channel 8012 communicating with the first channel 8011. The cross-sections of the first channel 8011 and the second channel 8012 are both circular, and the diameter of the first channel 8011 is greater than the diameter of the second channel 8012; the lock tongue 802 includes a tongue body 8021 and a stop portion 8022 connected to each other. The tongue body 8021 penetrates through the second channel 8012, and one end of the tongue body 8021 away from the stop portion 8022 is provided with a chamfer. The stop portion 8022 is located in the first channel 8011, and the diameter of the stop portion 8022 is greater than the diameter of the second channel 8012. The tongue body 8021 and the stop portion 8022 can slide in the second channel 8012 and the first channel 8011 respectively; the RF coaxial connector plug 100 further includes a second elastic member 12 located in the fifth through hole 502 and between the plug 11 and the stop portion 8022. The second elastic member 12 presses the stop portion 8022 to make the lock tongue 802 protrude from the lock sleeve 801. In specific implementation, the second elastic member 12 can be a compression spring. When the lock block 8 is in the locked position, most of the lock tongue 802 is inserted into the first gap 15. As Figure 11 shown, a circular mounting hole 8013 for connecting with the lever 9 is provided on the outer wall of the lock sleeve 801.

[0059] See Figure 15 shown, pushing the RF coaxial connector plug 100 to the left can connect the RF coaxial connector plug 100 with the RF coaxial connector socket 200; during the connection process of the RF coaxial connector plug 100 and the RF coaxial connector socket 200, when the lock tongue 802 contacts the third outer conductor 18 on the RF coaxial connector socket 200, the third outer conductor 18 on the RF coaxial connector socket 200 will drive the lock tongue 802 to move in a direction away from the center of the second outer conductor 2, so that the lock tongue 802 is received in the lock sleeve 801, thereby ensuring that the RF coaxial connector plug 100 can continue to move to the left and connect with the RF coaxial connector socket 200; during this process, only need to push the RF coaxial connector plug 100 to the left, without having to rotate the rotating shell 6 to move the lock block 8 to the unlocked position, so it is more convenient to use; and during the process of the lock tongue 802 moving in a direction away from the center of the second outer conductor 2, the lock tongue 802 will not drive the lock sleeve 801 and the lever 9 to move, nor can it drive the slot plate 7 and the rotating shell 6 to rotate, thus avoiding the rotation of the rotating shell 6 during the connection process of the RF coaxial connector plug 100 and the socket.

[0060] See Figure 10As shown, the slot plate 7 is made by cutting a metal plate. The slot plate 7 includes an annular body portion 701, an inner connecting plate 702, an ear plate 703, and a clamping block 704. Among them, the annular body portion 701 is circular. The inner connecting plate 702 and the ear plate 703 are both located inside the annular body portion 701 and fixedly connected to the annular body portion 701. The track groove 705 is arc-shaped and provided on the inner connecting plate 702. One end of the first elastic member 22 is connected to the ear plate 703.
