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 in which a seal member is difficult to be damaged during assembly. A seal member-accommodating portion that accommodates the seal member in a compressed state is formed as an intermediate portion of a through hole of a housing. When an insertion member is inserted into the through hole, an insertion portion of the insertion member presses the seal member into the seal member-accommodating 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： Provided is an optical connector adapter of the type in which a shell-side hollow cylindrical portion is integrally formed in a shell, a sleeve holder inserted in the shell has a holder-side hollow cylindrical portion, and a sleeve is held by the shell-side cylindrical portion and the holder-side cylindrical portion. The shell has an inward engaging projection on the inner periphery thereof at its portions facing the holder-side cylindrical portion while the sleeve holder has a holder locking portion. By engaging the holder locking portion with the engaging projection, the sleeve holder is prevented from being removed from the shell. The optical connector adapter is attached to a housing so as to pass through its wall such that the shell-side cylindrical portion is located outside the housing while the holder-side cylindrical portion is located inside the housing.

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.
