Description

Technical Field

[0001] The utility model relates to a double-locking radio frequency connector. Background Art

[0002] An RF connector is an electronic component used to connect RF circuits. It is mainly used to connect different RF devices or components together in RF signal transmission systems to achieve signal transmission and reception. RF connectors usually have the characteristics of high frequency performance, low loss, and strong adaptability. With the trend of miniaturization of electronic devices, RF connectors are also becoming more and more miniaturized to meet compact design requirements. Currently, common RF connector types include SMA connectors, SMB connectors, MCX connectors, N-type connectors, TNC connectors, etc.

[0003] Usually, RF connectors need to be locked at the end of electronic components to connect other electronic components. With the continuous development of RF technology, the stability and reliability requirements of connectors are getting higher and higher. Common locking structures include threaded locking, snap locking, spring locking, etc., while the traditional single locking structure has certain limitations. It is easy to loosen in harsh environments or under frequent vibrations, which may cause signal interruption or distortion. In some key areas, such as communications, aerospace, etc., it is easy to cause great losses. Utility Model Content
