Description

Technical Field

[0001] This utility model specifically relates to a modular multi-interface RF coaxial connector quick switching mechanism. Background Technology

[0002] In the rapid development of high-tech fields such as 5G communication, satellite communication, automotive electronics and aerospace, radio frequency coaxial connectors are key components for signal transmission.

[0003] Currently, mainstream RF connectors are still primarily single-interface designs, and most products adopt an integrated structure design. When it is necessary to change the interface type or repair a faulty component, the entire connector must be replaced, which not only increases maintenance costs but also extends equipment downtime. Although some multi-interface products use a fixed combination structure, there are still incompatibility issues between different models, and the replacement process for multi-interface RF connectors is relatively complex, seriously affecting replacement efficiency.

[0004] Therefore, it is necessary to invent a modular multi-interface RF coaxial connector quick switching mechanism to solve the above problems. Utility Model Content

[0005] (a) Purpose of the utility model To address the technical problems existing in the background art, this utility model proposes a modular multi-interface RF coaxial connector quick-switching mechanism, which can quickly replace interfaces.

[0006] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: a modular multi-interface RF coaxial connector quick switching mechanism, including a connection mechanism disposed inside the RF coaxial connector, wherein the connection mechanism includes a connector head and locking components fixed on both sides thereof; The RF coaxial connector has an installation port, and there are unlocking slots on both sides of the installation port that match the locking components. Unlocking blocks are installed in the unlocking slots. There are clamping components on both sides of the installation port below the unlocking slots. The clamping components on both sides clamp the outer wall of the connector. The locking component includes a fixing block with a telescopic groove inside. A locking block is installed in the telescopic groove. A telescopic spring is installed between the bottom of the locking block and the bottom of the telescopic groove. The locking block is engaged in the unlocking groove to fix the connector in the mounting port.

[0007] Preferably, the mounting port has positioning grooves on both sides, and the fixing blocks are installed in the positioning grooves on both sides. The unlocking groove is located above the positioning groove and is through the groove. The clamping assembly is located below the unlocking groove. The end edge of the unlocking block is provided with a limiting strip. The inner and outer sides of the unlocking groove are provided with limiting frames that match the limiting strip. The unlocking block moves in the unlocking groove, and the end of the unlocking block extends beyond its edge, that is, the end of the unlocking block pushes the locking block away from the unlocking groove.

[0008] Preferably, the front sides of the unlocking block are beveled, and the front is provided with an anti-slip plate.

[0009] Preferably, one side of the fixing block is set as an inclined surface, and a locking limit frame is provided at the opening of the telescopic groove. The end edge of the locking block is provided with a locking limit strip that matches the locking limit frame. The telescopic spring is fixed between the end of the locking block and the bottom of the telescopic groove. One side of the locking block is set as an inclined surface, and the slope of the inclined surface of the locking block and the fixed block is the same.

[0010] Preferably, the inner walls on both sides of the positioning groove are provided with clamping grooves for installing the clamping assembly. The clamping assembly includes a clamping plate placed in the clamping groove. A connecting post is connected to one side of the clamping plate. A limiting plate is provided at the end of the connecting post. A pull ring is connected to one end of the limiting plate. A through groove is provided at the bottom of the clamping groove. The connecting post is installed in the through groove. The limiting plate is placed outside the clamping groove. A clamping spring is provided between the bottom of the clamping groove and one side of the clamping plate.

[0011] Preferably, the connector has an inner conductor, and the end of the inner conductor is connected to the bottom connector of the mounting port.

[0012] Compared with the prior art, the beneficial effects of the above-mentioned technical solution of this utility model are: 1. The locking block of this utility model automatically engages with the unlocking slot under the thrust of the telescopic spring, realizing the quick positioning and fixation of the connector. When unlocking, it is only necessary to push the unlocking block whose end extends beyond the unlocking slot. Its end can directly push the locking block to compress the telescopic spring and disengage from the unlocking slot. No screwdriver or other tools are required throughout the process. Unlocking can be completed manually by a single person, which greatly shortens the interface switching time and is especially suitable for high-frequency switching scenarios. 2. The locking component of this utility model restricts the axial displacement of the connector head longitudinally by engaging the locking block with the unlocking groove, thus preventing the connection from falling off due to vibration. 3. The clamping assembly of this utility model clamps the outer wall of the connector laterally, further offsetting the radial sway of the connector and ensuring precise docking between the inner conductor and the bottom connector of the mounting port. The core performance of the RF coaxial connector depends on the stable contact of the inner conductor. Double fixing can effectively reduce signal interference and ensure the transmission quality of communication or test signals. Attached Figure Description

[0017] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0018] This utility model provides, for example Figure 1-5 The modular multi-interface RF coaxial connector quick switching mechanism shown includes a connection mechanism disposed inside the RF coaxial connector 1, and the connection mechanism includes a connector head 2 and locking components 3 fixed on both sides thereof; Specifically, the RF coaxial connector 1 has a mounting port 11, and the mounting port 11 has unlocking slots 12 for matching locking components 3 on both sides inside. Unlocking blocks 13 are installed in the unlocking slots 12. Clamping components 4 are provided on both sides inside the mounting port 11 below the unlocking slots 12. The clamping components 4 on both sides are clamped to the outer wall of the connector 2. Specifically, the locking component 3 includes a fixing block 31, a telescopic groove 32 is provided in the fixing block 31, a locking block 33 is installed in the telescopic groove 32, a telescopic spring 34 is installed between the bottom of the locking block 33 and the bottom of the telescopic groove 32, and the locking block 33 is inserted into the unlocking groove 12 to fix the connector 2 in the mounting port 11.

[0019] Specifically, the mounting port 11 has positioning grooves 14 on both sides, and fixing blocks 31 are installed in the positioning grooves 14 on both sides. The unlocking groove 12 is placed above the positioning groove 14 and is through the groove. The clamping component 4 is placed below the unlocking groove 12. The end edge of the unlocking block 13 is provided with a limiting strip 131. The inner and outer sides of the unlocking groove 12 are provided with limiting frames 121 that match the limiting strip 131. The unlocking block 13 moves in the unlocking groove 12, and the end of the unlocking block 13 extends beyond its edge, that is, the end of the unlocking block 13 pushes the locking block 33 to disengage from the unlocking groove 12.

[0020] Specifically, the front sides of the unlocking block 13 are beveled, and the front is provided with an anti-slip plate 132.

[0021] Specifically, one side of the fixed block 31 is set as an inclined surface, and a locking limit frame 35 is provided at the opening of the telescopic groove 32. The end edge of the locking block 33 is provided with a locking limit strip 36 that matches the locking limit frame 35. The telescopic spring 34 is fixed between the end of the locking block 33 and the bottom of the telescopic groove 32. One side of the locking block 33 is set as an inclined surface, and the slope of the inclined surface of the locking block 33 and the fixed block 31 is the same.

[0022] Specifically, the inner walls on both sides of the positioning groove 14 are provided with clamping grooves 41 for installing clamping components 4. The clamping components 4 include clamping plates 42 placed in the clamping grooves 41. A connecting post 43 is connected to one side of the clamping plate 42. A limiting plate 44 is provided at the end of the connecting post 43. A pull ring 45 is connected to one end of the limiting plate 44. A through groove 46 is provided at the bottom of the clamping groove 41. The connecting post 43 is installed in the through groove 46. The limiting plate 44 is placed outside the clamping groove 41. A clamping spring 47 is provided between the bottom of the clamping groove 41 and one side of the clamping plate 42.

[0023] Specifically, the connector 2 has an inner conductor 21 inside, and the end of the inner conductor 21 is connected to the bottom connector of the mounting port 11.

[0024] In this embodiment, the telescopic spring 34 in the locking assembly 3 is first installed at the bottom of the telescopic groove 32 of the fixing block 31, and then the locking block 33 is placed in the telescopic groove 32 so that the bottom of the locking block 33 contacts the telescopic spring 34. At the same time, it is ensured that the locking limit strip 36 at the end of the locking block 33 cooperates with the locking limit frame 35 at the opening of the telescopic groove 32 to complete the assembly of the locking assembly 3. Specifically, the assembled locking component 3 is installed on the corresponding positions on both sides of the connector 2 by means of fixing block 31, and fixed by welding or bolt connection to ensure that the locking component 3 is firmly connected to the connector 2. Specifically, the unlocking block 13 is installed in the unlocking slot 12 of the RF coaxial connector 1, so that the limiting strip 131 at the end of the unlocking block 13 cooperates with the limiting frame 121 at the opening of the unlocking slot 12, ensuring that the unlocking block 13 can move smoothly in the unlocking slot 12 and will not fall out of the unlocking slot 12. Specifically, the clamping plate 42 in the clamping assembly 4 is placed into the clamping groove 41 of the RF coaxial connector 1. Then, one end of the connecting post 43 passes through the through groove 46 at the bottom of the clamping groove 41 and connects to one side of the clamping plate 42 by welding. Next, a limiting plate 44 is installed at the other end of the connecting post 43 and is also fixed by welding. Finally, a pull ring 45 is installed at one end of the limiting plate 44 to complete the assembly and installation of the clamping assembly 4. Specifically, check whether each component is installed in place, ensure that the connector 2 can be smoothly inserted into the mounting port 11 of the RF coaxial connector 1, and that the locking component 3 can lock normally, the unlocking block 13 can normally push the locking block 33 to unlock, and the clamping component 4 can effectively clamp the connector 2.

[0025] In this embodiment, when it is necessary to connect the connector 2 to the RF coaxial connector 1, the connector 2 is first aligned with the mounting port 11 of the RF coaxial connector 1, and then slowly inserted. During the insertion process, the fixing blocks 31 in the locking components 3 on both sides of the connector 2 will move along the positioning grooves 14 on both sides of the mounting port 11. Since one side of the fixing block 31 is inclined and has the same slope as the locking block 33, under the pressure of insertion, the locking block 33 will be squeezed into the telescopic groove 32 and retract, while compressing the telescopic spring 34. When the connector 2 is inserted to the designated position, the locking block 33 pops out under the elastic force of the telescopic spring 34 and locks into the unlocking grooves 12 on both sides of the mounting port 11, realizing the initial locking of the connector 2 and the RF coaxial connector 1. At this time, the clamping plates 42 in the clamping components 4 on both sides of the mounting port 11 will be tightly attached to the outer wall of the connector 2 under their own elasticity or external pressure, further clamping and fixing the connector 2. At the same time, the end of the inner conductor 21 in the connector 2 is connected to the connector at the bottom of the mounting port 11 to ensure that the signal can be transmitted normally.

[0026] In this embodiment, when it is necessary to detach the connector 2 from the RF coaxial connector 1, the unlocking block 13 is pushed with a finger or tool. Since the front sides of the unlocking block 13 are beveled and the ends extend beyond its edge, during the pushing process, the ends of the unlocking block 13 will contact the locking block 33 and generate a pushing force into the telescopic groove 32 on the locking block 33. This causes the locking block 33 to retract into the telescopic groove 32 against the elastic force of the telescopic spring 34 until the locking block 33 is completely disengaged from the unlocking groove 12. At this time, the locking state of the connector 2 is released, and then the connector 2 can be pulled out from the mounting port 11 to complete the unlocking operation. During the pushing process of the unlocking block 13, the anti-slip plate 132 on the unlocking block 13 can effectively increase the friction between the finger or tool and the unlocking block 13, preventing slippage and facilitating operation. At the same time, the limiting strip 131 at the end of the unlocking block 13 cooperates with the limiting frame 121 at the opening of the unlocking groove 12 to limit the movement range of the unlocking block 13 and prevent the unlocking block 13 from falling out of the unlocking groove 12.

[0027] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
