Self-Locking Connectors

The HUBER+SUHNER self-locking solution is a simple and easy to use connector that eliminates the need for lockwire/safety wire that can lead to potential FOD in an aircraft. The anti-rotation microwave connector maintains the required torque to ensure the connector interface remains fully engaged throughout the operational profile that the aircraft may experience.

Our solution features a lock-collar mechanism that once engaged prevents rotation of the coupling nut. This design results in time savings during the initial cable assembly installation by eliminating lockwires and the associated equipment necessary to install it.  The size and weight of these connector assemblies are similar with standard connectors and maintains full function in harsh and/or high vibration environments.
