Abstract
A bayonet coupling connector having a coupling nut on a first coupling member arranged for cooperation with coupling pins of a second coupling member for enabling the two members to be joined together. The coupling nut carries a coupling ring provided with a spring loaded plunger which is capable of being displaced radially with respect to the nut, the coupling ring being effective for driving the coupling nut when the plunger is engaged therewith. The plunger further being capable of being displaced radially by a coupling pin of the second coupling member when the nut has been moved into a position where the two coupling members are locked together, the locking action thus causing the coupling ring to be suddenly disengaged from the nut thereby providing a tactile indication of the fully locked condition. The connector is suitable for different applications such as fluid supply lines and electrical connectors and it gives additional safety in reducing a risk of making a faulty connection between the members.
