摘要： In an optical connector for use in connecting an optical fiber, a shell member has an engaging portion. An internal member holds the optical fiber and is received in the shell member to be removable in a first direction. A stopper is engaged with the engaging portion in the first direction. A spring is engaged with the internal member and the stopper and urges the internal member towards a second direction opposite to the first direction. The shell member has a release operation portion for releasing the engaging portion from the stopper.

摘要： In an optical connector including an optical connector plug holding a first optical fiber and an optical connector plug holding a second optical fiber, the optical connector plugs cooperates with each other to obtain a connected state in which exposed longitudinal ends of the first and the second optical fibers are brought into contact with each other. The first optical fiber includes a long fiber portion and a short fiber portion higher in breakage resistance than the long fiber portion. One of the longitudinal ends of the short fiber is fused to one of longitudinal ends of the long fiber portion. Another of the longitudinal ends of the short fiber portion is exposed to serve as one of the exposed longitudinal ends.

摘要： The head end surface of an optical fiber (2) and the head end surface of an optical fiber (12) are butted to each other in an alignment member (22) of an adapter (21). In the butting, because one of the members clasping the optical fiber (2) is a plate (4a) that is short, the optical fiber (2) is bent and buckled between the left end of the short plate and the right end of the alignment member. Members clasping the optical fiber (12) are a long plate (14b) and a V-grooved base plate (13), and the optical fiber (12) is therefore horizontally fixed between each of right ends of the long plate and of the V-grooved base plate (13) and the left end of the alignment member. This results that the head end surface of the optical fiber (2) and the head end surface of the optical fiber (12) are in tight contact with each other, achieving excellent optical transmission between both optical fibers.

摘要： A disassembling tool includes a holding block having a housing portion for accommodating a plug connector, a slide block, and a handling part for sliding the slide block. The plug connector comprises an outer member and a plug frame and is accommodated in the housing portion of the holding block. When turning a handle of the handling part, the slide block is slidably moved so that projections provided on the slide block release the locking between locking portions of the outer member and locked portions of the plug frame. Following this, contact portions provided on the slide block come into contact with the plug frame so as to push it out of the outer member by a given amount.

摘要： A splice module for optically interconnecting ends of first and second optical fibers (200, 300), each of which has a predetermined radius (Rf). The splice module comprises first and second plates (20, 30), both of which are made of silicon. The first plate 20 is provided with grooves (22). The second plate (30) is arranged on the first plate (20) to cover the grooves (22) and to define passage ways (26) for receiving and aligning the ends of the first and the second optical fibers (200, 300). The passage way (26) has an inscribed circle (28), which has a radius (Ri) larger than the predetermined radius (Rf) by a predetermined difference (D) between 0.5 μm and 1.0 μm, both inclusive.

摘要： There is provided a connector which is capable of routing a flat cable in a desired arbitrary direction and at the same time preventing the flat cable from being broken. A concave portion is formed in a housing, and a convex portion is formed on a cable-holding member for being slidably fitted in the concave portion. Slits are formed in the concave portion, and projections to be engaged with the slits are formed on the cable-holding member. Thus, directions of rotations of the cable-holding member are restricted such that the cable-holding member can rotate only about a first axis extending in a direction of width of the flat cable and a second axis orthogonal to the first axis and extending in a direction of insertion of the flat cable.

摘要： An optical fiber connector (100), which is used for interconnecting ends of optical fibers (200) together with a splice device or a similar device, comprises a connector body (10) and a protector (50), which is movably or slidably held by the connector body (10). The connector body (10) is provided with an arranging portion (23), which is separated from and independent of the protector (50). The arranging portion (23) arranges the optical fibers (200) so that the arrangement of the optical fibers (200) falls within a single closed predetermined area in an XZ plane perpendicular to a Y-direction, wherein the single closed predetermined area has a first area size in the XZ plane. The protector (50) is provided with a front end surface (52a), which is formed with a second opening (54). The second opening (54) has a second area size in the XZ plane, which is larger than the first area size. When the optical fibers (200) are held by the optical fiber connector (100), the second opening (54) is never in contact with the optical fibers (200) even during the protector (50) is moved.
