Abstract: A ferrule for an optical fiber connector has a cylindrical sleeve or body (1) and a capillary (3) received in the sleeve 1. The sleeve (1) has thereinside a fiber holding portion (2a) adjoining one end of the sleeve (1) and for holding a built-in optical fiber (4), a capillary holding portion (2b) next to the fiber holding portion (2a), and a fiber inserting portion (2c) next to the capillary holding portion (2b) and for inserting an optical fiber (6). The fiber holding portion (2a) and the fiber inserting portion (2c) have the smallest diameter and the largest diameter, respectively. The diameter of the capillary holding portion (2b) is substantially equal to the outside diameter of the capillary 3. The axis of the fiber holding portion (2a) is accurately coincident with the axis of the sleeve (1). The capillary (3) is held in the capillary holding portion (2b) while the fiber (4) extends over the fiber holding portion (2a) and a through bore formed in the capillary 3. A through notch (5) is formed in the capillary (3) and filled with a refractive index matching material (7). The Fiber (6) is inserted into and affixed to the ferrule via the fiber inserting portion (2c).

Abstract: A package member has fitted in a through hole thereof a pipe member with an optical fiber inserted therein, the optical fiber including a jacketted part thereof fitted in and soldered to an inside region of the pipe member, with a solder filled therebetween, and a stripped part thereof fitted in and fixed to another inside region of the pipe member, with an adhesive filled therebetween, while the pipe member is fixed to the package member by a welding along a circumference of the through hole, without using a fixing ring, permitting a relatively high hermeticity to be achieved in a facilitated fabrication process.

Abstract translation: 包装件在其通孔中装配有插入其中的光纤的管构件，该光纤包括其套管部分，并将其焊接到管构件的内部区域中，其中填充有焊料，并且剥离 其部分装配并固定到管构件的另一内部区域，其中填充有粘合剂，而管构件通过沿着通孔的圆周的焊接固定到包装构件，而不使用固定环，允许 在便利的制造过程中要实现的相对较高的气密性。

Abstract: An optical connector has a ferrule with an flange having a polygonal cross-section, and a housing into which the ferrule is inserted. The housing has a stopper to be in contact with a side surface of the flange for regulating a position of the ferrule, a guide member for guiding the ferrule in the housing, the guide member having a regulation portion for finally regulating the position of the flange, and a slope portion on which the flange slides for guiding the ferrule to the regulation portion.
