Patent ID: 7093983

Claim:
An optical connector plug comprising: a plug frame for holding a ferrule in which an optical fiber is held; a plug housing having a plug frame holding hole in which the plug frame is held in a manner that allows the plug frame to move axially, the plug frame holding hole piercing through the entire length of the plug housing; a shielding plate whose proximal end is held to one side of an inner surface of the plug frame holding hole of the plug housing in a manner that allows the shielding plate to tilt, and whose distal end moves between a shielding position, at which the shielding plate shields a front end face of the ferrule, and an unshielding position, at which the shielding plate allows the plug frame to move; an operating plate whose proximal end is held, in a tiltable manner, to the one side of the inner surface of the plug frame holding hole at a position nearer to the center of the optical connector plug than the shielding plate, and whose distal end is in contact with or is engaged with the shielding plate to tilt along with the shielding plate, the plug frame being capable of retracting, upon movement of the shielding plate to the shielding position, to a housing position at which no interference occurs with the shielding plate and the operating plate; and biasing and holding means for biasing and positioning the shielding plate and the operating plate in a manner that brings the shielding plate to the shielding position as the plug frame moves to the housing position, wherein, when the plug frame is moved toward a front end of the plug housing, the operating plate is tilted by this movement of the plug frame, and the tilted operating plate pushes the shielding plate to the unshielding position, allowing the plug frame to move to an optical connection position with respect to the plug housing.
