摘要： In an optical connector, a holding member is coupled to a ferrule and attached to a housing. The ferrule has a flange portion brought into contact with the contact surface. The ferrule is adapted to receive an optical fiber. The housing has a contact surface and an engaging surface faced inward with respect to each other in an optical axis direction. The holding member includes a cylindrical main body for receiving the ferrule inserted therein, a first engaging portion connected to the main body and engaged with the engaging surface, and a second engaging portion connected to the main body and engaged with the flange portion, the second engaging portion being elastically deformable.

摘要： In a fixing tool for fixing a fiber holding member to an optical fiber, a tool body receives the optical fiber and the fiber holding member. In this event, the fiber holding member is disposed on a first specific part of the optical fiber. A positioning device fixes a second specific part of the optical fiber to the tool body in the state where the optical fiber and the fiber holding member are received in the tool body. The second specific part is a portion between the first specific part and a longitudinal end face of the optical fiber.

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： There is provided an optical connector module of which an optical transmission/reception wafer and an optical waveguide wafer can be registered with each other easily and accurately without misregistration. An optical transmission/reception wafer has guide pin-receiving V-grooves with a V-shaped cross-section, formed at locations preset in association with an optical transmission/reception end of an optical transmission/reception section. An optical waveguide-side connector has an optical waveguide wafer formed with guide pin-receiving V-grooves in association with the guide pin-receiving V-grooves of the optical transmission/reception wafer. Wafer registration guide pins are inserted in these guide pin-receiving V-grooves, and the optical transmission/reception wafer and the optical waveguide wafer are brought close for interconnection such that these guide pins are tightly sandwiched by the guide pin-receiving grooves.
