It includes three parts: the BNC connector base, the jacket, and the probe. The BNC connector is one of the most common RF connectors. It is a small, quick-connect bayonet connector. In order to improve the efficiency of high-frequency signal transmission, a BNC male RF connector is needed. However, the existing BNC male RF connector still has the following shortcomings:

[0003] For example, the utility model with application number 202222259778.7 discloses a new type of BNC male RF connector, which fixes the connector to the upper end of the cable and can protect the drill nail on the upper end of the sleeve through a connecting sleeve connected to the outer end of the sleeve, thereby preventing the drill nail from falling off and keeping the connector and cable easy to disassemble, solving the problem of the press-fit connection between the existing connector and the cable being difficult to disassemble. However, similar to the comparative documents of the above-mentioned application, when the existing BNC male RF connector is used, since most BNC male RF connectors are connected by pressing, there is a risk of the sleeve shaking during use, which affects the connection stability and lacks protective performance, resulting in reduced practicality and reduced efficiency of the BNC male RF connector.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a BNC male RF connector with good waterproof performance is proposed. Utility Model Content
