    • PROBLEM TO BE SOLVED: To provide an optical connection component which eliminates the risk of buckling a coated optical fiber when removing the coating and has high reliability and assembly easiness.SOLUTION: An optical connection component 1 is provided which connects a coated optical fiber 11 and an optical component 12 with each other, and comprises a coating removing unit 64 which is capable of removing a coating 14 of the coated optical fiber 11, a front hole 61 which is provided forward rather than the coating removing unit 64, a rear hole 63 which is provided backward rather than the coating removing unit 64, a crimping unit 71 which crimps the coated optical fiber, and a protecting unit 72 which extends forward from the crimping unit 71 or backward from the rear hole 63 and covers an outer periphery of the coated optical fiber 11. The optical connection component is characterized in that the protecting unit 72 includes an opening part 72a which opens a part of the outer periphery of the coated optical fiber 11 and is constituted so as to be closed, and at the back of the rear hole 63 or in front of the crimping unit 71, a protecting unit accommodation recess 66 is formed which accommodates the protecting unit 72 therein in the state where the opening part 72a is closed.
    • 要解决的问题:提供一种在去除涂层时消除了涂覆光纤弯曲的风险的光学连接部件,并且具有高可靠性和组装容易性。 解决方案:提供一种将涂覆的光纤11和光学部件12彼此连接的光学连接部件1,并且包括能够去除涂覆的光纤11的涂层14的涂层去除单元64, 设置在前方而不是涂层去除单元64的前孔61,设置在后面而不是涂层去除单元64的后孔63,卷曲涂覆光纤的压接单元71和延伸的保护单元72 从卷边单元71向前方或从后孔63向后方覆盖被覆光纤11的外周。光连接部件的特征在于,保护单元72包括:开口部72a,其开口部的外周 涂布光纤11被构造成封闭,并且在后孔63的后部或卷曲单元71的前方,形成保护单元容纳凹部66 d,其中开口部72a关闭的状态下容纳保护单元72。 版权所有(C)2013,JPO&INPIT

    • PROBLEM TO BE SOLVED: To provide a simply handled closure for optical cable connection in a low cost configuration. SOLUTION: A closure main body 5 is provided with a cable guiding in and out section 1 and core storage trays 4 in which a supporting connection section storage section 2 of a connection section C that mutually connects cores and a core extra length storage section 3 are formed. A cover body 6 is arranged in a freely attachable and detachable manner for the closure main body 5 to attain an optical cable connection closure D. A lower most layer passing core storage tray 4 1 is provided to the closure main body 5 to form a tray holder 8 having a fitting engaging section 7 of a plurality of core storage trays 4 that store pull-down cores. The core storage trays 4 are provided to the engaging section of the tray holder 8 in a freely engaging and disengaging manner. On top of the lower most layer passing core storage tray 4 1 , the plurality of core storage trays 4 are arranged in a freely turnable manner and in a multistage and stacked manner as top layer trays and a plurality of core storage sheets 9 are mounted in a freely turnable manner on the center section of the lower most layer passing core storage tray 4 1 .
