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： A plug (2) that includes a plug frame (7) is inserted into an opening of a housing (4) and is retained by a pair of spring-like detent pieces (6) extending into the opening. Projecting portions (6a) on the detent pieces engage recess portions (15) on right and left hand sides of the plug frame. A cylindrical lug (13) is slidably mounted on the plug frame and includes an opening portion (14) and inclined surfaces (17) to permit plug removal. The inclined surfaces (17) serve as cams to lift the projection portions (6a) out of the recess portions (15) when the lug is moved rearwardly. A stopper (3) is insertable into the plug frame to block such rearward sliding motion of the lug on the frame to prevent removal of the plug from the housing. The stopper may include a locking inward projection (3d) for engaging a hole (13b) bored in the lug to block rearward motion of the lug on the plug frame. Alternatively, the stopper may include outwardly projecting resilient stepped pieces (3i, 3j) that fit into the hole in the lug (13). Rearward sliding motion of the lug on the frame is enabled by pressing the pieces (3i, 3j) inwardly.

摘要： This invention presents a method and an apparatus for adjusting the axial orientation angle between the principal axis of a polarization maintaining fiber (PMF) and a ferrule with ease and precision. The invented ferrule is composed of a ferrule body, having a through hole into which a PMF is inserted, and a ring-shaped flange, having a keyway on the circumferential rim, installed on the outer periphery of the ferrule body. An engaging part is provided on the periphery to restrain the forward movement of the ferrule body by engaging with the flange. The invented ferrule enables adjustment of the axial angle, between the principal axis of the PMF and the keyway of the flange, to be made after adhesively bonding the PMF onto the ferrule body and polishing the end of the fiber. Therefore, the axial angle adjustment is carried out conveniently and accurately, without being affected by the processing effects, such as curing of the adhesive. Further, when the cable joint is made by joining the plugs, even if the spring compression forces, acting to press together the ferrule bodies, acted on the flange, the forward movement of the flange is restrained by the engaging part, thereby minimizing the adverse residual stress effects on the optical performance properties of the cable.
摘要翻译：本发明提供了一种方法和装置，用于容易且精确地调节偏振保持光纤（PMF）的主轴与套圈之间的轴向取向角。本发明的套圈由插入有PMF的通孔和环形凸缘的环形凸缘构成，环形凸缘安装在套圈本体的外周上。在周边设置有接合部，以通过与凸缘接合来限制套圈主体的向前运动。本发明的套圈能够将PMF的主轴与凸缘的键槽之间的轴向角度调整为在将PMF粘合到套圈体上并抛光光纤的端部之后进行。因此，轴向角度调整方便，准确地进行，而不受加工效果的影响，例如粘合剂的固化。此外，当通过连接插头制造电缆接头时，即使用于将套圈本体压在一起的弹簧压力作用在凸缘上，凸缘的向前移动被接合部分约束，从而最小化不利的残余应力对电缆光学性能的影响。
