Abstract
Description
Technical Field
[0001] This utility model relates to the field of radio frequency connection technology, and in particular to a stable radio frequency coaxial connector. Background Technology
[0002] Radio frequency (RF) connectors primarily function as signal interconnects and power transmitters in various electronic devices. After connection, RF connectors can transmit various voltage and current signals, microwave and radio frequency signals, or power, and are widely used in electronics, communications, computers, automobiles, energy, and aerospace fields.
[0003] Common RF coaxial connectors typically consist of a housing and pins. The pins are inserted into the sockets of the housing, and the housing and pins are connected together by soldering or other methods. The inner wall of the socket of a common RF coaxial connector housing is made of beryllium bronze plated with gold, and the inner wall is provided with insulating material to wrap the pins. The common insulating material is PTFE.
[0004] To improve stability, the pins are usually fixed in the socket by soldering after being inserted into the housing. In practice, laser soldering is often used. However, during soldering, the pins may become misaligned during transportation, causing them to be misaligned during soldering. Alternatively, the pins may wobble or rotate during soldering, resulting in misalignment after soldering, which affects the use of the connector. Therefore, the assembly of RF coaxial connectors is prone to producing defective products, and the overall assembly quality needs to be improved. Utility Model Content
[0005] To improve assembly quality, this application provides a stable RF coaxial connector.
[0006] This application provides a stable RF coaxial connector using the following technical solution: A stable RF coaxial connector includes a housing and pins. The pins are provided with an assembly ring block. The housing is provided with a through hole and an assembly groove communicating with the through hole. The pins pass through the assembly groove and are inserted into the through hole. The assembly ring block is inserted into the assembly groove. The assembly ring block is provided with a positioning block. The housing is provided with a fixing groove identical to the assembly groove. The fixing block is slidably disposed in the fixing groove. The housing is provided with a positioning groove connecting the assembly groove and the fixing groove. The positioning block is inserted into the positioning groove. The fixing block is provided with a pressing block capable of abutting against the positioning block. The pressing block is inserted into the positioning groove. A fixing spring is provided in the fixing groove, and the fixing spring connects the inner wall of the fixing groove and the fixing block.
[0007] By adopting the above technical solution, during assembly, the fixing block is pulled and the fixing spring is stretched, so that the fixing block is away from the outer shell. Then, the assembly ring block is inserted into the assembly groove, and the positioning block is inserted into the positioning groove. After that, the fixing block is released, the fixing spring returns to its original position, and the fixing block is pulled back into the fixing groove, so that the pressing block abuts against the top wall of the positioning block, thereby completing the limiting and fixing of the assembly ring block, improving the stability of the assembly. By having the positioning block abut against the side wall of the fixing groove and the pressing block abut against the positioning block, the possibility of the assembly ring block shaking or rotating during the welding process is reduced, thereby improving the stability of the welding and improving the overall assembly quality.
[0008] Preferably, the fixing block is provided with a sliding block, the inner wall of the fixing groove is provided with a sliding groove, and the sliding block is slidably disposed in the sliding groove.
[0009] By adopting the above technical solution, the sliding block slides within the sliding groove, thereby improving the stability of the fixed block's sliding motion.
[0010] Preferably, the fixing spring is disposed in the sliding groove and connects the sliding block to the top wall of the sliding groove.
[0011] By adopting the above technical solution, the fixed spring connects the top wall of the sliding block and the top wall of the sliding groove, so that the fixed spring is compressed after the fixed block slides. Compared with the tension fixed spring, this reduces the possibility of elastic failure of the fixed spring after long-term tension and improves durability.
[0012] Preferably, the positioning block can be inserted into the fixing groove, the assembly ring block can be inserted into the positioning groove, the assembly ring block is provided with a first limiting block, the inner wall of the assembly groove is provided with a first limiting groove, and the first limiting block can be inserted into the first limiting groove.
[0013] By adopting the above technical solution, the fixing spring is not set in the fixing groove, allowing the positioning block to be inserted into the fixing groove. During assembly, after the fixing block is pulled out, the assembly ring block is inserted into the assembly groove. When the first limiting block jams the outer shell, the assembly ring block is pushed into the positioning groove, so that the positioning block is inserted into the fixing groove vacated by the outward movement of the fixing block. This allows the first limiting block to be inserted into the assembly groove. When the assembly ring block abuts against the bottom wall of the assembly groove, the assembly ring block is pushed out of the fixing groove, allowing the first limiting block to be inserted into the first limiting groove. The operation is simple and convenient. By inserting the first limiting block into the first limiting groove and abutting against the inner wall of the first limiting groove, the stability of the assembly ring block in the assembly groove is further improved, thereby improving the stability of assembly and welding and improving the assembly quality.
[0014] Preferably, the inner wall of the assembly groove is provided with a second limiting block, and the assembly ring block is provided with a second limiting groove, wherein the second limiting block can be inserted into the second limiting groove.
[0015] By adopting the above technical solution, during assembly, when the assembly ring block is inserted into the assembly groove, the first limiting block will lock the outer shell, and the assembly ring block will lock the second limiting block. At this time, the assembly ring block is pushed into the positioning groove, so that the positioning block is inserted into the fixing groove. The assembly ring block continues to move down, and when the assembly ring block abuts against the bottom wall of the assembly groove, it is pushed out of the fixing groove, so that when the first limiting block is inserted into the first limiting groove, the second limiting block is inserted into the second limiting groove. This further improves the stability of the assembly ring block in the assembly groove, thereby improving the stability of assembly and welding, and improving the assembly quality.
[0016] Preferably, the assembly ring block is provided with an auxiliary groove, the first limiting block is slidably disposed in the auxiliary groove, and an auxiliary spring is provided in the auxiliary groove, the auxiliary spring connecting the inner wall of the auxiliary groove and the first limiting block.
[0017] By adopting the above technical solution, when the first limiting block is stuck in the outer shell, the first limiting block can be pushed into the auxiliary groove to compress the auxiliary spring, and the assembly ring block can be pushed into the assembly groove. When the assembly ring block abuts against the bottom wall of the assembly groove, the first limiting block is aligned with the first limiting groove. At this time, the auxiliary spring returns to its original position and pushes the first limiting block into the first limiting groove, thus improving the convenience of assembly.
[0018] Preferably, the pin is provided with a glass insulator, which connects the pin to the assembly ring block.
[0019] By adopting the above technical solutions, the glass material has better high-temperature resistance, which improves the high-temperature resistance of the connector. The glass insulator reduces the possibility of the pin fixing material softening due to high temperature after long-term use, causing the pin to shake, thus improving the stability of the pin and improving the stability of signal transmission. This reduces the impact of problems such as unstable signal transmission, poor mechanical performance and sealing performance.
[0020] Preferably, the pin is sintered with glass to connect to the glass insulator, the assembly ring is sintered with the glass insulator, and the assembly ring is welded to the outer shell.
[0021] By adopting the above technical solution, the glass sintering connection of the pin, glass insulator and assembly ring block improves the stability of the connection between the three, while the welding connection of the assembly ring block and the shell improves the assembly stability and reduces the possibility of liquid penetration, thus improving durability.
[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. By setting up a shell, pins, assembly ring blocks, through holes, assembly slots, positioning blocks, positioning slots, fixing slots, fixing blocks, fixing springs, and pressing blocks, during assembly, the fixing blocks are pulled to slide away from the shell while the fixing springs are stretched, so that when the assembly ring blocks are inserted into the assembly slots and the positioning blocks are inserted into the positioning slots, the pressing blocks will not interfere with the positioning blocks. Then the assembly ring blocks are inserted into the assembly slots, so that the pins are inserted into the through holes of the shells. After that, the fixing blocks are released, the fixing springs return to their original state, the fixing blocks are inserted into the fixing slots, and the pressing blocks press against the positioning blocks, thus completing the assembly. This improves the stability of the assembly, thereby improving the welding and assembly quality. 2. By setting a sliding block and a sliding groove, the sliding block slides in the sliding groove to improve the stability of the fixed block sliding. At the same time, the fixed spring connects the top wall of the sliding block and the top wall of the sliding groove, so that the fixed spring is compressed after the fixed block slides. Compared with the tensioning of the fixed spring, the risk of the fixed spring being damaged by excessive tension during use is reduced, thus improving durability. 3. By setting a first limiting block, a first limiting groove, a second limiting block, and a second limiting groove, and by using a fixing block to make way for the fixing groove, the positioning block can be inserted into the fixing groove, the assembly ring block can be inserted into the positioning groove, the first limiting block can be inserted into the first limiting groove, and the second limiting block can be inserted into the second limiting groove, thereby improving the stability of the assembly, thus improving the stability of the assembly and welding, and improving the assembly quality.

[0028] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.
[0029] This application discloses a stable RF coaxial connector. (Refer to...) Figures 1 to 2 The device includes a housing 1 and a pin 2. The pin 2 can be connected to other devices and radio frequency sources to transmit signals. The housing 1 has a through hole 11 and an annular assembly groove 12 communicating with the through hole 11 on its back. A glass insulator 21 made of sintered glass is arranged around the pin 2. An assembly ring block 3 is also fitted over the glass insulator 21. The glass insulator 21 is fixed between the pin 2 and the glass insulator 21 by glass sintering. The pin 2 passes through the assembly groove 12 and is inserted into the through hole 11. The assembly ring block 3 is adapted to be inserted into the assembly groove 12. A semi-circular positioning block 31 is fixedly arranged on the outer wall of the assembly ring block 3. The back of the housing 1 has a positioning groove 14 identical to the assembly groove 12. The positioning block 31 is adapted to be inserted into the positioning groove 14 and its length is half the length of the positioning groove 14. The back of the outer casing 1 is provided with a semi-circular arc-shaped fixing groove 13 that communicates with the positioning groove 14. The length of the fixing groove 13 is greater than the length of the assembly groove 12. A fixing block 4 is slidably disposed in the fixing groove 13. A pressing block 41 is integrally fixed on the side wall of the fixing block 4, which is inserted into the positioning groove 14 and abuts against the positioning block 31. The top wall of the pressing block 41, the top wall of the fixing block 4, and the back of the outer casing 1 are flush. After the assembly ring block 3 is inserted into the assembly groove 12, it abuts against the positioning block 31 through the pressing block 41 and the bottom wall of the assembly groove 12 abuts against the assembly ring block 3, thereby improving the stability of the assembly ring block 3 assembly, reducing the possibility of the assembly ring block 3 shaking or rotating during the welding process, thereby improving the welding stability and improving the overall assembly quality.
[0030] To improve assembly convenience, refer to Figures 1 to 3 The inner wall of the fixing groove 13 is provided with an arc-shaped sliding groove 15. An arc-shaped sliding block 42 is integrally fixed to the outer wall of the fixing block 4 on the side away from the assembly ring block 3. The sliding block 42 is adapted to slide within the sliding groove 15, and the distance between the top wall of the sliding groove 15 and the back of the outer shell 1 is less than the distance between the bottom wall of the fixing groove 13 and the bottom wall of the assembly groove 12. A fixing spring 43 is provided within the sliding groove 15 to connect the top wall of the sliding groove 15 and the sliding block 42. When the fixing block 4 is pulled away from the outer shell 1, the sliding block 42 slides within the sliding groove 15 and compresses the fixing spring 43. This design is simple, convenient, and easy to use. To further improve assembly stability, refer to Figures 2 to 4The positioning block 31 can be inserted into the fixing groove 13, and the assembly ring block 3 can be inserted into the positioning groove 14. The assembly ring block 3 has an auxiliary groove 34 and a second limiting groove 33 on the side away from the positioning block 31. The auxiliary groove 34 is located near the back of the outer casing 1, and the first limiting groove 16 is located near the bottom wall of the assembly groove 12. A first limiting block 32 is slidably disposed in the auxiliary groove 34, and an auxiliary spring 341 connecting the inner wall of the auxiliary groove 34 and the first limiting block 32 is disposed in the auxiliary groove 34. The inner wall of the assembly groove 12 has a first limiting groove 16 on the side away from the positioning groove 14, and a second limiting block 17 is fixedly disposed thereon. The first limiting block 32 can be inserted into the first limiting groove 16, and the second limiting block 17 can be inserted into the second limiting groove 33. The depth of both the second limiting groove 33 and the first limiting groove 16 is less than the thickness of the fixing block 4. By inserting the first limiting block 32 into the first limiting groove 16 and cooperating with the second limiting block 17 into the second limiting groove 33, the stability of the assembly ring block 3 before it is pressed against the positioning block 31 by the pressing block 41 is improved, thereby further improving the stability of the assembly.
[0031] The implementation principle of a stable RF coaxial connector according to an embodiment of this application is as follows: During assembly, the wire is connected to the pin 2 and the assembly ring block 3 via glass insulator 21 through glass sintering. Then, the fixing block 4 is pulled out, causing the sliding block 42 to compress the fixing spring 43. When the space between the pressing block 41 and the back of the outer shell 1 is sufficient to accommodate the positioning block 31, the assembly ring block 3 is inserted into the assembly groove 12 until the first limiting block 32 locks the outer shell 1 and the second limiting block 17 locks the assembly block. At this time, the assembly ring block 3 is pushed into the positioning groove 14, causing the positioning block 31 to be inserted into the fixing groove 13. The assembly ring 3 continues to slide within the assembly groove 12 until it abuts against the bottom wall of the groove. At this point, the positioning block 31 is disengaged from the fixing groove 13, and the assembly ring 3 is disengaged from the positioning groove 14, causing the first limiting block 32 to insert into the first limiting groove 16 and the second limiting block 17 to insert into the second limiting groove 33. The fixing block 4 is then released, and the fixing spring 43 returns to its original position, pushing the fixing block 4 into the fixing groove 13. This causes the pressing block 41 to insert into the positioning groove 14, abutting against the positioning block 31, making the top wall of the pressing block 41, the top wall of the fixing block 4, and the back of the outer shell 1 flush. At this point, the top wall of the pressing block 41, the top wall of the fixing block 4, and the back of the outer shell 1 can be welded and fixed together using laser welding, filling any gaps.
[0032] By performing the above assembly operations, the possibility of the assembly ring 3 shaking or rotating during the welding process is reduced, thereby improving the stability of the welding and reducing the possibility of the pin 2 being misaligned after welding, so as to improve the overall assembly quality.
[0033] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
