摘要： For connecting an optical fiber having a fiber axis and an axial end portion provided with a chamfered surface having a predetermined angle with respect to the fiber axis, the optical connector includes an aligning member and a holding plate. The aligning member has a principal surface and a side surface adjacent to the principal surface. The aligning member has a fiber-receiving groove for receiving the axial end portion of the optical fiber. The fiber-receiving groove extends along the principal surface in a predetermined direction and has end portions each opening on the side surface. The holding plate is faced to the principal surface and covers the fiber-receiving groove. The holding plate has a first slant surface beside one of end portions of the fiber-receiving groove. The first slant surface has an angle with respect to the principal surface. The first angle is determined smaller than the predetermined angle.

摘要： There is provided an optical fiber end face cleaner which is easy to carry and make preparations for use, facilitates cleaning operation, and what is more, makes it possible to positively remove or clear away attached materials from end faces of optical fibers without causing any of the removed materials to adhere to the end faces again. The optical fiber end face cleaner includes at least one elastic base formed by an elastic member having a flat surface of a predetermined size, and a predetermined thickness in a direction perpendicular to the surface. An adhesive layer is formed on a surface of the elastic base, for allowing the end faces of the optical fibers to be pressed against the adhesive layer to cause deposits on the end faces to adhere to the adhesive layer for removal.

摘要： An optical connector includes a housing including a coupling portion for coupling another optical connector and a blocking component for blocking an optical axis arranged in the coupling portion. The blocking component has a shutter plate blocking the optical axis and being pivotably supported by the housing with a pivot shaft and an elastic portion for normally biasing the shutter plate to a closed position. The shutter plate pivots between a position blocking the optical axis and a position to which the shutter plate is forced to move by the other optical connector when the other optical connector is inserted into the optical connector.

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.
