摘要： PROBLEM TO BE SOLVED: To provide an optical connector and an optical connector assembly tool to improve reliability and assembly workability.SOLUTION: An optical connector comprises: a ferrule 1; a flange 2 holding the ferrule 1 and including a pore part 8 in which a coated portion of an optical fiber inserted into the ferrule 1 is bent and an optical fiber bending regulating part 9; and an optical fiber holding part 3 for elastically holding the optical fiber. The pore part 8 has an inner diameter sized to allow bending of the optical fiber. The optical fiber bending regulating part 9 is a cylinder which is located at a portion nearer to the ferrule 1 than a center position of the pore part 8 and has a major axis on a center axis of a major axis direction of the ferrule 1, and has a hole diameter slightly larger than an outer diameter of the coated portion of the optical fiber. The optical fiber holding part 3 elastically holds the coated portion of the optical fiber in the state of an end of the optical fiber projecting from an end face of the ferrule 1 and presses and connects end faces of optical fibers with each other by elastic recovery force generated by bending of the optical fibers.

摘要： PROBLEM TO BE SOLVED: To restrain damage of the front end face of an optical fiber in a chamfering process without complicating the structure of a holder. SOLUTION: A polishing surface 24 of a polishing member 10 intersects with the axis of an intermediate part of an optical fiber F, and also inclines to the orthogonal plane of the axis of the intermediate part of the optical fiber F. When optical fiber F is made to approach the polishing surface 24, the tip of the optical fiber F obliquely comes into contact with the polishing surface 24, and also in separating, the tip of the optical fiber F separates from the polishing surface 24 while keeping its oblique attitude to the polishing surface, so that damage of the front end face of the optical fiber F can be restrained. Since the track of the polishing member 10 includes a revolution component and a rotation component, a large polishing amount can be obtained and also abrasion of the polishing member 10 can be restrained, although the position of the tip of the optical fiber F is in the vicinity of a revolution axis (ar).

摘要翻译：要解决的问题：在倒角过程中抑制光纤前端面的损伤而不会使保持器的结构复杂化。解决方案：抛光构件10的抛光表面24与光纤F的中间部分的轴线相交，并且也倾斜到光纤F的中间部分的轴线的正交平面。当光学使纤维F接近研磨面24，光纤F的前端倾斜地与研磨面24接触，并且在分离时，光纤F的前端与研磨面24分离，同时保持其倾斜对抛光面的姿态，能够抑制光纤F的前端面的损伤。由于抛光构件10的轨道包括旋转分量和旋转分量，所以可以获得大的抛光量，并且即使光纤F的尖端的位置在...中，也可以抑制抛光构件10的磨损旋转轴（ar）附近。版权所有（C）2009，JPO＆INPIT

SOLUTION: A core wire 9 is inserted into an extension member 50 of a plug 4 set on a main body 1. Upper end surfaces 5a (guide surfaces) of a pair of guide projection streaks are extended while offset upward from a guide groove 3a, so a tip portion of the core wire 9 is held obliquely to the guide groove 3a and elastically curved to correct the attitude of the tip portion. The respective upper end surfaces 5a are made parallel to the guide groove 3a, so the attitude of the core wire 9 can be maintained before and after the core wire 9 is shifted in holding point along the upper end surfaces 5a of the guide projection streaks 5.
