摘要： In an optical connector, end faces of a pair of ferrules that hold multiple optical fibers are positioned with two guide pins and butted against each other to connect the optical fibers in the pair of ferrules. The optical connector is provided with an urging member for pushing the end faces against each other. The end faces are ground at an angle. The gap between the guide pins and guide holes, which open at the end faces and into which the guide pins are fitted, is larger than 0.004 mm and smaller than or equal to 0.008 mm. Powder caused by the friction generated when the guide pins are inserted and fitted into the guide holes is greatly reduced. Connection loss does not increase even when frequent connection and disconnection are performed, and cleaning the connector becomes unnecessary.

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.
