Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of radio frequency coaxial connectors, and more specifically to an anti-rotation radio frequency coaxial connector. Background Art
[0002] RF coaxial connector is a connector used to connect RF devices or cables. It is commonly used in communications, broadcasting, electronic equipment, wireless networks and other fields. These connectors transmit RF signals through coaxial cables and provide reliable connection and shielding of signals. They are suitable for various RF applications, including military, aerospace, communications, medical and other fields.
[0003] Existing RF coaxial connectors are mainly fixed by directly plugging the interfaces into each other, which has low stability. Especially when subjected to external force, the connector body and the transmission line will rotate. Once the connector rotates during use, it may cause the connection to be unstable or disconnected, thereby causing signal interruption or damage, which may affect the normal operation of communication systems, radar systems or other RF equipment, and may also cause damage to the device interface or connector seat. Especially in the case of frequent connection and disassembly, this may cause equipment failure, damage or need for maintenance. To this end, we propose an anti-rotation RF coaxial connector to solve the above problems. Utility Model Content

[0011] Technical effects and advantages of the utility model:
[0012] When the utility model is in use, the connector is inserted into the docking groove, and the fixed plug rod moves upward along the sliding groove to squeeze the spring. When it contacts the second plug hole, the rebound force of the spring decreases and pushes the fixed plug rod to move down and insert it into the second plug hole. At the same time, one end of the docking line is inserted into the plug hole. After completing basic data connection, the connector is fixed, and the operation is convenient. Therefore, it can effectively avoid that the connector and the transmission line will not rotate easily after the data connection. The stability after connection is qualitatively improved, and the rotation phenomenon of the coaxial connector body is effectively prevented, thereby ensuring the stability of the coaxial connector body after connection. When the coaxial connector body needs to be unplugged, at this time, it is only necessary to turn the rotating dial block in sequence so that the rotating dial block can be flipped 90 degrees along the slight axis, so that the fixed plug rod moves up along the sliding groove and disengages from the second plug hole, which is convenient for plugging and unplugging the connector, and improves the service life of the coaxial connector body and the equipment carrier board, which is conducive to improving the practicality of the device.
