A CONNECTION SYSTEM WITH A BAYONET-TYPE LOCKING DEVICE ADAPTED TO ALLOW A QUICK DISCONNECTING OPERATION

摘要

A connection system with two system elements forming a plug and a receptacle. A locking device including a locking nut mounted free in rotation around the plug or the receptacle, and a locking pin arranged into the locking nut. The locking pin is adapted to be engaged into a locking ramp provided in the receptacle or the plug by relative translation between the plug and the receptacle and rotation of the locking nut to mechanically lock the plug to the receptacle when they are in mutual connection. The arrangement of the locking pin is such that a pull force applied to a sliding part of the locking nut, in a sense opposite to the sense of their mutual connection, disengages the locking pin from the locking ramp, allowing the unlocking of the plug from the receptacle.
