Claims

[Scope of utility model registration request]

In a bayonet type optical connector, in which a pair of plugs are inserted into an adapter from both directions, the ferrule end faces of each plug are brought into contact with each other, and optical fibers held at the axis of the ferrules are connected to each other, the ferrule is inserted into the end of the plug body. At the same time, a cylindrical member is rotatably fitted to cover the tip of the plug body via a bearing, and on the outside of the cylindrical member is a coupling that can be freely fitted and locked with the adapter. A bayonet type optical connector characterized in that a nut is elastically held via a spring disposed between the nut and the tip of the cylindrical member.
