摘要： A strain-relief assembly for a field-installable fiber optic connector is disclosed, wherein the assembly includes a ferrule holder, an intermediate sleeve, and a crimp sleeve. The ferrule holder back section holds a buffered section of a fiber optic cable, while the ferrule holder front end holds a ferrule and a splice assembly. A stub fiber is held within the ferrule and the splice assembly so as to interface with a section of field optical fiber protruding from the buffered section. The intermediate sleeve engages and generally surrounds a portion of the ferrule holder back section and thus surrounds a portion of the buffered layer. An intermediate sleeve handler may be used to handle the intermediate sleeve and attached the intermediate sleeve to the ferrule holder back section. Stress-relief strands from the fiber optic cable are flared around the outer surface of the intermediate sleeve. A crimp sleeve is placed over the intermediate sleeve to hold the ends of the stress-relief strands in place. The crimp sleeve is then crimped, which fixes the strand ends in place and also fixes the intermediate sleeve in place on the ferrule back section.

摘要： An improved mechanical crimp provides increased fiber retention, while reducing the force required to form the crimp so that the crimp can be formed using a compact crimp mechanism disposed on a handheld installation tool. The crimp includes a deformable crimp tube and an optical fiber disposed within the crimp tube. A radial cross section of the crimp defines a plurality of alternating concave and convex outer surfaces. The crimp mechanism includes a base plate and a pair of crimp arms movably mounted on the base plate such that the crimp arms define a crimp area. The crimp mechanism further comprises an eccentric engaging at least one of the crimp arms and movably mounted on the base plate between a first position wherein the crimp arms are spaced apart at the crimp area and a second position wherein the crimp arms are not spaced apart at the crimp area.
摘要翻译：改进的机械卷曲提供增加的纤维保持力，同时减少形成卷曲所需的力，使得可以使用设置在手持式安装工具上的紧凑的压接机构来形成卷边。卷曲包括可变形的压接管和设置在卷曲管内的光纤。卷曲的径向横截面限定多个交替的凹凸外表面。压接机构包括基板和可移动地安装在基板上的一对压接臂，使得压接臂限定卷曲区域。压接机构进一步包括偏心接合至少一个压接臂并可移动地安装在基板上的第一位置和第二位置之间，其中压接臂在压接区域处间隔开，第二位置处压接臂不间隔开卷曲区域。
