材３３にはステンレスを用いられることが多い。Conventionally, this type of ferrule is composed of a capillary 32 that holds and fixes the strand 31a of the optical fiber 31 on its axis, and a terminal member 33 that holds the capillary 32, as shown in FIG. Here, the material of the capillary 32 is ceramic, glass, etc., and the terminal member 33 is often made of stainless steel.

があった。When the conventional optical fiber connector ferrule mentioned above is assembled at a location other than an optical component manufacturing factory, such as on-site while an optical cable is being installed, the adhesion between the optical fiber and the ferrule of the optical fiber connector is mainly due to the main material. Since the epoxy adhesive is a mixture of two types of liquids: a liquid and a hardening agent, it is necessary to carry a stirrer, a measuring device, a container, etc., and to fill the inside of the ferrule with an appropriate amount of adhesive. The disadvantage was that it required work to coat the optical fiber.

不要となる効果がある。As explained above, according to the present invention, by sealing an appropriate amount of uncured ultraviolet curable adhesive inside the optical fiber connector ferrule, the assembly work of the optical fiber connector can be accomplished by simply inserting the optical fiber into the ferrule. Since only ultraviolet rays are irradiated, the number of steps required to assemble the optical fiber connector ferrule can be reduced, and there is no need to carry adhesives, stirrers, measuring instruments, etc. to the assembly site.

This has the effect of completely eliminating the phenomenon of poor connection of optical fibers.
