OPTICAL CONNECTOR PLUG WITH SHUTTER

摘要

An optical connector plug with a shutter to be fitted to an optical connector adapter includes: a plug frame configured to hold a ferrule; a square cylindrical front housing including a shutter that opens and closes with a movement of the ferrule; a locking housing fixedly and integrally connected to the plug frame and configured to be fitted into and be locked with the optical connector adapter; and a spring that biases the front housing forward. The plug frame is moved forward by a rearward movement of the front housing, a front opening edge portion of the plug frame expands a shutter into a straight shape, and the shutter includes slits straddling over a boundary between a flat portion and a curved portion when light is blocked, and a protrusion formed by a center portion being deformed by the expanded shutter when being fitted is cancelled.

主权项

1. An optical connector plug with a shutter to be fitted to an optical connector adapter, comprising:
a plug frame configured to hold a ferrule; a square cylindrical front housing arranged so as to be slidable on the plug frame and including a shutter configured to open and close in association with a movement of the ferrule at a distal end side opening; a locking housing fixedly and integrally connected to the plug frame configured to be fitted into and be locked with the optical connector adapter; and a spring configured to bias the front housing forward, wherein the plug frame relatively moves forward by a rearward movement of the front housing so that a front opening edge portion of the plug frame expands the shutter which is curved on an optical axis of the distal end side opening of the front housing and blocking light into a straight shape, and the shutter includes a slit so as to straddle over a boundary portion between a flat portion and a curved portion in a state in which light is blocked, and a protrusion formed by a center portion being deformed in a state in which the shutter is expanded when being fitted into the optical connector adapter is cancelled.
