摘要： In a plug-in connector for connecting elements mounted on a backage board to other elements arranged on a back wiring board disposed perpendicular to the package board, the guide pin and the connector housing fixing screw are formed integral with each other to realize a floating connector coupling structure which is high in mounting efficiency and precision and small in size. Further, the plug-in connector can connect two different, optical and electrical connectors. Further, there is disclosed a novel optical connector plug whose radial eccentricity direction can be matched with that of a mated optical connector jack with an optical fiber aligning jig to minimize the optical fiber coupling power loss.

摘要： To provide an optical connector which can slidably and stably support the optical connector element (ferrule) within the connector housing without increasing the axial length of the ferrule, the optical connector plug comprising: (a) a plug housing (202) formed with a shoulder portion (253) between a large hollow portion (254) and a small hollow portion (252) and formed with no projection between said two portions; (b) a plug ferrule (201) connected to an optical fiber (204) and formed with a flange portion (201b) slidably fitted into the large hollow portion of said plug housing and an end portion (201a) passed through the small hollow portion of said plug housing; and (c) a spring (203) housed within said plug housing to urge the flange portion of said plug ferrule against the shoulder portion (253) of said plug housing. A mated jack ferrule (201) is fitted to the small hollow portion (252) of said plug housing (202) via a sleeve holder (206) having a floating slit sleeve (205) therewithin so as to absorb an axial dimensional fitting error between the plug ferrule and the jack ferrule by axially urging the flange portion (201b) of said plug ferrule by an inner end of the sleeve holder (206) against said spring (203).

摘要： To microscopically clean the ferrule end surface of an optical connector simply, uniformly and securely, the optical connector cleaner comprises a cleaning cloth woven with ultrafine fiber less than 0.1 denier; a casing formed with at least one opening for protecting the cleaning cloth from dust; and a mechanism for shifting the cleaning cloth exposed in the opening for cloth renewing, after the ferrule end surface has been rubbed with the cleaning cloth for cleaning. Further, it is preferable to provide an elastic member under the cleaning cloth for applying a constant cleaning pressure against the cloth and a guide member over the cleaning cloth for securely cleaning the ferrule end surface. The cloth shift mechanism is operated manually by the user or automatically by a motor. A holder jig holds the optical connector to facilitate cleaning of the ferrule end surface. The holder jig supports the optical connector such that the ferrule projects from the holder jig.

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.
