摘要： An optical connector assembling jig and an optical connector assembling method includes an optical connection. The optical connector assembling jig includes a base and a guide. The base is provided in a longitudinal direction with an accommodation groove for accommodating an optical fiber, and a rear pressing member for restraining a rear part of the optical fiber accommodated in the accommodation groove. The rear part is set apart from an embedded fiber. The guide has a front holding portion for holding a front part of the optical fiber accommodated in the accommodation groove. The front part is near the embedded fiber, and the guide is capable of moving in the longitudinal direction. Moving the base toward the optical connector causes the intermediate section of the optical fiber to separate from the accommodation groove and bend. By moving the base further toward the optical connector, a buffered fiber in the optical fiber can be connected to the embedded fiber.

摘要： A cantilever type latch having the fixed end on the side of exposing the terminal end surface of the optical fiber is provided on the side of the plug housing. Near the center of the upper surface of the latch, an engaging projection which is to be engaged in the engaging hole formed in the adapter or the receptacle is formed. The engaging projection has the slope which decreases the height toward the fixed end side of the latch, in which the gradient of the slope is nearly equal to or greater than the rotation angle required for the elastic deformation of the latch with the fixed end functioned as the fulcrum. Thereby easy disconnecting of the latch is implemented.
