OPTICAL CONNECTOR AND OPTICAL CONNECTOR FERRULE
An optical connector comprises a housing, a regulating portion which is protrudes toward an inner surface of the housing, a ferrule which is secured to an optical fiber and which is accommodated inside the housing so as to be movable. The ferrule includes a base portion and a thinned portion that has a thickness smaller than that of the base portion. If the ferrule moves forward in the butt-connection direction, the regulating portion and the base portion approach each other, so that the regulating portion regulates the movement of the ferrule in the thickness direction. If the ferrule moves backward in the butt-connection direction, the ferrule reaches a position where the thinned portion faces the regulating portion, so that the movement of the ferrule in the thickness direction is not regulated by the regulating portion.
1 . An optical connector comprising:
a housing;
a regulating portion which protrudes toward an inner surface of the housing;
a ferrule which is secured to an optical fiber, and which is accommodated inside the housing so as to be movable in a butt-connection direction,
wherein the ferrule comprises:
a base portion, which has a first thickness extending in a thickness direction that is perpendicular to the butt-connection direction; and
a thinned portion, which is formed at a front side of the base portion and has a second thickness that is smaller than the first thickness,
wherein if the ferrule moves forward in the butt-connection direction, the regulating portion and the base portion approach each other so that the regulating portion regulates the movement of the ferrule in the thickness direction, and
wherein if the ferrule moves backward in the butt-connection direction, the regulating portion and the thinned portion separate from each other so that the movement of the ferrule in the thickness direction is not regulated by the regulating portion.
2 . The optical connector according to claim 1 ,
wherein a plurality of regulating portions is provided at upper and lower inner surfaces of the housing.
3 . The optical connector according to claim 1 ,
wherein the housing accommodates:
an inserting optical fiber having an end portion fixed to an end surface of the ferrule at a joint portion, and another end portion connected to the optical fiber, and
a joint reinforced portion which reinforces the joint portion.
4 . An optical connector ferrule, which is secured to an optical fiber in a butt-connection direction, and which is insertable into a housing of an optical connector, the ferrule comprising:
a base portion having a thickness in a thickness direction that is perpendicular to the butt-connection direction;
a thinned portion that is in front of the base portion and has a thickness smaller than the thickness of the base portion,
wherein the ferrule is movable in the butt-connection direction;
wherein if the ferrule moves forward in the butt-connection direction, the base portion moves toward an inner surface of the housing and movement of the ferrule in the thickness direction is regulated as the base portion approaches the housing, and
wherein if the ferrule moves backward in the butt-connection direction, the movement of the ferrule in the thickness direction is released as the thinned portion separates from the housing.
