Abstract

PURPOSE:To simplify the structure of a terminal tool and to attain remarkable cost reduction by forming grooves in the repeatedly used terminal forming jig at specific pitch of optical fibers. CONSTITUTION:The substrate 32 of the terminal tool is set in the recessed part 38 of the terminal forming jig. Then, coating parts 22 of optical fiber cores 21 are set in the recessed part 34 of the substrate 32 and optical fibers are set in grooves 37 of the terminal forming jig 35 to array terminals of the optical fiber cores 21. Then, a pressure plate 40 is placed on a coating part storage groove 39 to fix the coating parts 22 of the optical fiber cores. In this state, an adhesive is applied over the coating parts 22 in the substrate 22 and the lid 33 of the terminal tool is placed thereupon. Thus, the coating parts 22 of the optical fiber core terminals and the terminal tool 3 are united and then taken out of the terminal forming jig 35.
