ABSTRACT:
The present invention seeks to provide an optical connector with an in-swinging shutter for closing a plug insertion opening of the connector, to avoid interference between the shutter and a plug holding part provided inside a plug insertion hole, to avoid increase in the outer dimensions of the connector by suppressing the accommodating space of the shutter. The in-swinging shutter has a two-piece hinge configuration in combination of a main shutter on the basal side and a sub shutter on the distal side. The sub shutter is hinge-coupled to the opening side end of the main shutter. The main shutter is elastically held at the closed position by a bias spring. The sub shutter is elastically held by another bias spring in a bent state in which it is bent towards the insertion opening side, or in a straightened state extending along the extended line of the basal side shutter.
