Abstract
Description
Technical Field
[0001] This utility model relates to the field of radio frequency connection technology, and in particular to a radio frequency coaxial connector with stable signal connection. 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 used to connect the communication cables at both ends to achieve signal connection. In the existing technology, the assembly between the housing and the pins is usually achieved by setting a ring-shaped insert on the pin. The housing has a through hole and an assembly groove with the same through hole. The insert is inserted into the assembly groove and threadedly connected to the assembly groove, so that the pin is inserted into the through hole.
[0004] However, in actual use, in order to ensure the stability of the communication connection, the connection between the plug and the assembly slot needs to be very stable. However, the threaded connection between the plug and the assembly slot is manually rotated by the assembler, which is greatly affected by the assembler's strength. If the rotation is not tightened enough, the threaded connection will not be tight enough. During long-term use, the threads may loosen further, and the plug may wobble or bend in the through hole, affecting the quality of the signal connection and causing the signal connection to be unstable. Utility Model Content
[0005] To improve signal connection stability, this application provides a radio frequency coaxial connector with stable signal connection.
[0006] This application provides a stable signal connection radio frequency coaxial connector using the following technical solution:
[0007] A stable radio frequency coaxial connector includes a housing and pins. The housing has a through hole and an assembly groove identical to the through hole. The pins are provided with an assembly block, which is inserted into the assembly groove. The outer wall of the assembly block is provided with a mounting groove. An mounting rod is slidably disposed in the mounting groove. An mounting spring is provided in the mounting groove to connect the mounting rod and the inner wall of the mounting groove. The inner wall of the assembly groove is provided with a mounting slot, into which the mounting rod is inserted.
[0008] By adopting the above technical solution, during assembly, the mounting rod is pushed back into the mounting slot and the mounting spring is compressed. Then, the assembly block is inserted into the assembly slot. When the assembly block abuts against the bottom wall of the assembly slot, the mounting rod is aligned with the mounting slot. The mounting spring returns to its original position and pushes the mounting rod into the mounting slot, thus completing the installation. During use, the side wall of the mounting rod abuts against the inner wall of the mounting slot, thereby improving the stability of the assembly and reducing the possibility of the assembly block shaking and causing the pins to shake and sway during use, thus improving the stability of the signal connection.
[0009] Preferably, the inner wall of the assembly slot is provided with a locking groove, a locking rod is slidably disposed in the locking groove, a locking spring is provided in the locking groove to connect the locking rod and the inner wall of the locking groove, the assembly block is provided with a locking slot identical to the mounting slot, the mounting rod is provided with a locking hole, and the locking rod can be inserted into the locking slot and into the locking hole.
[0010] By adopting the above technical solution, when the assembly block is inserted into the assembly slot, the locking rod is inserted into the locking slot until it abuts the mounting rod. The mounting rod continues to move with the assembly block, thereby pushing the locking rod to compress the locking spring. When the mounting rod is aligned and inserted into the mounting slot, the locking rod is aligned with the locking hole. The locking spring returns to its original position and pushes the locking rod into the locking hole, thereby further locking and fixing the mounting rod. This improves the stability of the mounting rod assembling and fixing the assembly block and the housing, thereby reducing the possibility of the mounting rod shaking during use, which may cause the pin to shake and affect the signal quality, and improving the stability of the signal connection.
[0011] Preferably, the assembly block is provided with an auxiliary groove that communicates with both the locking slot and the mounting slot. An auxiliary block is provided in the auxiliary groove, and the auxiliary block can abut against the locking rod. The mounting rod is provided with a connecting component, which is used to connect the mounting rod and the auxiliary block.
[0012] By adopting the above technical solution, the auxiliary block is connected to the mounting rod through the connecting component and moves with the mounting rod. The auxiliary block abuts against the locking rod, reducing the possibility of the locking rod wearing down the mounting rod and reducing the probability of damage to the mounting rod, thereby improving durability and assembly stability, and further improving the stability of the signal connection.
[0013] Preferably, the auxiliary groove is provided with an auxiliary spring connecting the inner wall of the auxiliary groove and the auxiliary block, and the locking rod is provided with an auxiliary hole, into which the auxiliary block can be inserted.
[0014] By adopting the above technical solution, before the mounting rod is inserted into the mounting slot, the auxiliary block abuts against the locking rod. When the mounting rod is inserted into the mounting slot, the auxiliary block is connected to the mounting rod through the connecting component and moves together to compress the auxiliary spring, so as to make way for the locking rod to pass through. After the locking rod is inserted into the locking hole, the connection between the auxiliary block and the mounting rod is released through the connecting component. At this time, the auxiliary spring returns to its original state and pushes the auxiliary block to move and insert into the auxiliary hole, thereby positioning and fixing the locking rod, further improving the stability of the assembly.
[0015] Preferably, the connecting assembly includes a connecting rod, a connecting support rod, and a connecting spring. The mounting rod is provided with a connecting groove, and the connecting rod is slidably disposed in the connecting groove. The connecting spring is disposed in the connecting groove and connects the connecting rod to the inner wall of the connecting groove. The mounting rod is provided with a connecting support groove that connects the connecting groove and the locking hole. The connecting support rod is slidably disposed in the connecting support groove and connected to the connecting rod. The auxiliary block is provided with a connecting slot, and the connecting rod is inserted into the connecting slot. The locking rod is provided with an abutment groove, and the connecting support rod can be inserted into the abutment groove and abut against the inner wall of the abutment groove.
[0016] By adopting the above technical solution, the connecting spring pushes the connecting rod to move and insert into the connecting slot, thereby connecting the auxiliary block and the mounting rod. When the mounting rod moves and inserts into the mounting slot, the connecting rod drives the auxiliary block to move and compresses the auxiliary spring. When the locking rod is inserted into the locking hole, the locking support rod is inserted into the abutment groove and pushed by the inner wall of the abutment groove, thereby driving the connecting rod to move and compress the connecting spring, causing the connecting rod to exit the connecting slot and release the connection between the mounting rod and the auxiliary block. At this time, the auxiliary spring returns to its original position and pushes the auxiliary block to insert into the auxiliary hole. The overall operation is simple, convenient, automatic, and easy to use.
[0017] Preferably, the auxiliary block is provided with a limiting block, the mounting rod is provided with a limiting groove, and the limiting block is slidably inserted into the limiting groove.
[0018] By adopting the above technical solution, the sliding of the limiting block within the limiting groove improves the stability of the auxiliary block's sliding.
[0019] Preferably, the pin is provided with a glass insulator, which is disposed between the pin and the assembly block.
[0020] 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.
[0021] Preferably, the assembly block is provided with a sealing block, and the outer shell is provided with a sealing groove that communicates with the assembly groove.
[0022] By adopting the above technical solution, the sealing block is inserted into the sealing groove during assembly, thereby improving the overall sealing performance of the assembly.
[0023] In summary, this application includes at least one of the following beneficial technical effects:
[0024] 1. By setting up a housing, pins, through holes, assembly slots, assembly blocks, mounting rods, mounting grooves, mounting slots, and mounting springs, the mounting rod is pushed back into the mounting groove and the mounting spring is compressed, the assembly block is inserted into the housing assembly groove, so that the pins are inserted into the through holes, until the mounting rod is aligned with the mounting slot. At this time, the mounting spring returns to its original position and pushes the mounting rod into the mounting slot, completing the installation. The mounting rod abuts against the inner wall of the mounting slot, thereby improving the stability of the pin and housing assembly, reducing the possibility of the assembly block shaking and causing the pin to shake or sway during use, and improving the stability of the signal connection.
[0025] 2. By setting a locking groove, locking rod, locking hole, locking spring, and locking slot, when the assembly block is inserted into the assembly groove, the locking rod is inserted into the locking support rod and abuts against the mounting rod. The mounting rod continues to move, pushing the locking rod to move in the locking groove and compressing the locking spring until the mounting rod is aligned and inserted into the mounting slot. At this time, the mounting rod is aligned with the locking hole, and the locking spring returns to push the locking rod into the locking hole, further locking and fixing the mounting rod. This improves the overall stability when the mounting rod fixes the assembly block to the housing, reduces the possibility of the pin shaking due to the shaking of the mounting rod during use, and improves the stability of the signal connection.
[0026] 3. By setting up auxiliary slots, auxiliary blocks, auxiliary springs, auxiliary holes, and connecting components, when the locking rod is inserted into the locking slot, the locking rod abuts against the auxiliary block. When the mounting rod is inserted into the mounting slot, the connecting components drive the auxiliary block to move synchronously in the auxiliary slot and compress the auxiliary spring. When the locking rod is inserted into the locking hole, the connecting components are disconnected, the auxiliary spring returns to its original state and pushes the auxiliary block into the auxiliary hole, positioning and fixing the locking rod, further improving the stability of the assembly, thereby improving the stability of the signal connection.
