摘要： When plug is fitted to adapter, optical fiber is inserted to an alignment hole for the optical fiber. By providing a taper at the entrance thereof, even if the tip of the optical fiber is deviated from the central position, the deviation is absorbed to make it possible for the optical fiber to be inserted smoothly. When two plugs is fitted to adapter, the tip of one optical fiber is confronted with the other one in the alignment hole, and excessive length L.sub.1 -L.sub.2 is pushed into the two optical fiber-bending spaces with a suitable distribution, thus the optical fiber buckles therein. The end face of the optical fiber is subjected to flat surface-polishing, removal of ripples after being cleaved, or chamfer grinding after being cleaved. The buckling portion of the optical fiber is coated with carbon or the like.

摘要： A cylindrical split alignment sleeve of ceramic material has an axial slit and is used in an optical fiber connector for connecting optical fibers to each other. In order to establish the strength reliability of the split ceramic alignment sleeve, a predetermined stress is applied to it by a test procedure ensuring no damage to the sleeve. According to the invention, a test load is applied to the inner circumferential surface of the split ceramic alignment sleeve by a loading part which includes stationary and movable members having inclined slidable contact surfaces. The sleeve is applied onto the load part and the movable member is displaced to apply load to the sleeve. The magnitude of load can be detected by deformation of the loading part or by displacement of the movable member.

摘要： A plug (2) that includes a plug frame (7) is inserted into an opening of a housing (4) and is retained by a pair of spring-like detent pieces (6) extending into the opening. Projecting portions (6a) on the detent pieces engage recess portions (15) on right and left hand sides of the plug frame. A cylindrical lug (13) is slidably mounted on the plug frame and includes an opening portion (14) and inclined surfaces (17) to permit plug removal. The inclined surfaces (17) serve as cams to lift the projection portions (6a) out of the recess portions (15) when the lug is moved rearwardly. A stopper (3) is insertable into the plug frame to block such rearward sliding motion of the lug on the frame to prevent removal of the plug from the housing. The stopper may include a locking inward projection (3d) for engaging a hole (13b) bored in the lug to block rearward motion of the lug on the plug frame. Alternatively, the stopper may include outwardly projecting resilient stepped pieces (3i, 3j) that fit into the hole in the lug (13). Rearward sliding motion of the lug on the frame is enabled by pressing the pieces (3i, 3j) inwardly.

摘要： The sleeve holder for an optical connector capable of preventing slip-off or disconnecting of the sleeve holder from a housing and eliminating breaking of a split sleeve due to the increase of an insertion force of the ferrule by maintaining always no-load state for engaging pieces. A tube-shaped main body inserted and held in the housing is mounted therein with a slider slidable in an axis direction. A split sleeve inserting and holding the ferrule is mounted at the insides of a tube body and the slider fixedly engaged coaxially with the main body, and such mount of the split sleeve together with the slider is slidable by a predetermined stroke in the axis direction.
