[0002] Radio frequency coaxial connector, also called RF connector, is an important component in radio frequency and microwave signal transmission. It is a connection device used to connect coaxial transmission lines. It is mainly used to achieve interconnection between devices / modules and effectively transmit radio frequency and microwave signals. It is widely used in wireless communication, broadcasting, television, radar and other fields. Radio frequency coaxial connector. Radio frequency coaxial connector usually consists of inner conductor, outer conductor, insulator and connector. The inner conductor and outer conductor are the center conductor and the outer metal shielding layer respectively, separated by an insulator in the middle to prevent signal interference and leakage. Therefore, radio frequency coaxial connector has the characteristics of good high-frequency transmission performance, strong anti-interference ability, convenient and reliable installation, etc.

[0003] At present, when the RF coaxial connector is connected to the anti-interference device, it is necessary to insert the internal pin of the RF coaxial connector into the female connector on the anti-interference device. During the insertion process, due to operational errors, the pin is often pushed into the insulator, and even bent and cannot be used. The entire RF coaxial connector needs to be reassembled. For this reason, we propose an anti-slip RF coaxial connector for anti-interference equipment. Utility Model Content
