摘要： An optical connector is selectively attachable to one of optical fiber cables including a first type optical fiber cable and a second type optical fiber cable. Each of the optical fiber cables includes a common optical fiber and a common ferrule fixed to the common optical fiber. The first type optical fiber cable further includes a tension member. The second type optical fiber cable further including a tensile member. The optical connector has a swage portion through which the common ferrule is inserted forward when one of the optical fiber cables is attached to the optical connector. The swage portion has an outer surface on which the tensile member is swaged when the second type optical fiber cable is attached to the optical connector. The optical connector also has a fixing portion having at least one receiver hole formed therein for receiving and fixing an end of the tension member of the first type optical fiber cable. The fixing portion is located forward of the swage portion.

摘要： An optical connector device has a first connector including a ferrule for holding an optical fiber and a guide portion projecting longer than the ferrule. The optical connector device also has a second connector for receiving an end of the ferrule along an optical axis of the optical fiber. The second connector includes a receiver for receiving the guide portion and a shutter having a cover part. The shutter is movable between a cover position at which the optical axis intersects the cover part and an open position at which the optical axis does not intersect the cover part. The guide portion is operable to move the shutter from the cover position to the open position when the guide portion is received into the receiver.

摘要： A stopper 50 is fixed to an optical connector 10, and the optical connector 10 is accommodated in an opening section 21 of a housing 20. The housing 20 is engaged with the stopper 50 so as to be displaceable with respect to the stopper 50 by a predetermined amount in a direction of inserting the optical connector 10 to a receptacle, and the stopper 50 is biased rearward by a coil spring 40 with respect to the housing 20. The free end of a clip piece 15 is placed on the free end of a latch piece 14 of the optical connector 10, and the free end of the clip piece 15 is placed on an inclination surface 23a at the front end of a concave section 23 formed on an inner wall surface of the opening section 21. At the time of detachment from the receptacle, the housing 20 is displaced in a direction to be pulled out against the biasing force of the coil spring 40. Accordingly, the clip piece 15 and the latch piece 14 are pushed down by the inclination surface 23a to release the lock of the latch piece 14. The detachment from the receptacle can be made in one motion.
