Optical connector

An optical connector plug to be inserted to an adapter, is arranged such that a pair of engaging parts for expanding an elastic locking piece provided on a side of the adapter by a taper part and locking it with a step part is provided on a tip part of a plug frame which is a body of the plug; a locking releasing piece movable along an insertion-extraction direction is provided between the pair of engaging parts; a taper part for releasing a locking action of the elastic locking piece when extracting the plug is provided at a rear end of the locking releasing piece; and the taper part of the engaging parts has such a shape that the connecting stress is not lowered before being locked when inserting the plug.

Optical connector plug

A shading member-equipped optical connector plug is compact while having the compatibility to engage existing connector receptacles. The connector plug includes a shading member having a shutter housing enclosing a plug frame slidably on an outside thereof. The shutter housing is inserted into an engagement opening of a connector receptacle to be engaged when the shading member-equipped optical connector is connected. The shading member also has a shutter one end of which is supported by the shutter housing at a front part of the housing and another end of which is urged by an elastic force and closes so as to shade the optical fibers at a position in front of the ferrule, and an elastic member disposed between the plug frame and the shutter housing that urges the shutter housing forward.
