OPTICAL FERRULE AND OPTICAL CONNECTOR

摘要

An optical ferrule and an optical connector are provided, which make it possible to reduce the labor required for an adhesive wiping operation even when the optical ferrule is small-sized. A first adhesive filling recess 113 is equipped, which is formed at an outlet of an optical fiber hole 112 so that a forward end of a bare fiber 120, which is positioned by the optical fiber hole 112, is allowed to abut against an inner wall 113w opposed to the outlet, and the bare fiber 120 is adhered and fixed in a resultant state by means of an adhesive 131 with which the recess is filled, wherein the first adhesive filling recess 113 is provided with adhesive accommodating recesses 115, 117 which are shallower than the first adhesive filling recess 113 and are disposed continuously with the first adhesive filling recess 113.

主权项

1. An optical ferrule comprising:
a positioning structure which positions an optical fiber in a longitudinal direction and in a perpendicular direction thereof, the optical fiber being inserted from an inlet disposed on a back end side of the optical ferrule; and a first adhesive filling recess which is formed at an outlet of the positioning structure so that a forward end of the optical fiber, which is inserted into the positioning structure, protrudes from the outlet to abut against an inner wall of the first adhesive filling recess opposed to the outlet, and the optical fiber is adhesively fixed in a resultant state by means of an adhesive with which the recess is filled, wherein: the first adhesive filling recess is provided with adhesive accommodating recesses which are provided only at side edge portions disposed on both sides of the first adhesive filling recess in the longitudinal direction of the optical fiber, the adhesive accommodating recesses include a first adhesive accommodating recess and a second adhesive accommodating recess, the first adhesive accommodating recess and the second adhesive accommodating recess being shallower than the first adhesive filling recess, the first adhesive accommodating recess is disposed at a front of the first adhesive filling recess and disposed continuously with the first adhesive filling recess, the second adhesive accommodating recess is disposed at a rear of the first adhesive filling recess and disposed continuously with the first adhesive filling recess.
