Description

Locking radio frequency connector of swivel nut locking

Technical Field

The utility model belongs to the technical field of radio frequency connectors, and particularly relates to a threaded sleeve locking anti-loosening radio frequency connector.

Background

The radio frequency connector is used as a transmission element of radio frequency signals, and the stability of the connection structure of the radio frequency connector has a great influence on the stability of signal transmission. The male connector is usually connected with the female connector with an external thread by a movable threaded sleeve with an internal thread, and the movable threaded sleeve is easy to loosen after long-time use or under vibration conditions, so that the signal is unstable or even has no signal, and therefore, anti-loosening measures must be taken in occasions with frequent connection and separation or severe use conditions. The common anti-loosening method is to punch a hole on the threaded sleeve and then bind the threaded sleeve and the female connector by using a steel wire, so that the anti-loosening effect can be achieved, but the anti-loosening method is very troublesome to use and is particularly suitable for occasions needing frequent separation. Therefore, it is very urgent to design a connector with convenient use and good anti-loose effect.
