Technical Field

[0001] The utility model relates to the technical field of RF connectors, in particular to an anti-loosening type RF connector. Background Art

[0002] The connection of RF connectors is generally carried out by using an inner hole and an inner needle. During the connection process, the male and female heads are docked and inserted to achieve connection. After searching, the Chinese patent authorization number CN219643231U discloses an RF connector. Although the connector has a simple structure and is easy to disassemble and assemble, it can quickly connect and disconnect the connector, and the connection is more firm and stable, avoiding the male and female heads from falling off during use due to the pulling of the cable. However, when the male and female heads are docked, the positioning column needs to be aligned with the vertical groove before they can be inserted. In addition, the positioning column is small in size. When operating in an environment with poor light or a small space, the positioning column cannot be quickly aligned with the vertical groove for insertion, and multiple rotations are required to adjust the docking angle of the male and female heads, thereby reducing the convenience of using the connector.
