Title: Optical fiber sensor head and its manufacture
Inventor: INAI SHIGERU
IPC: G02B6/02
Filed: 1993-03-31
Abstract: PURPOSE:To prevent the end face of an optical fiber which is mirror finished from projecting to the end face of a cap by forming a bank-shaped protrusion in specific dimensions on the end face at the tip port side of the through hole for inserting and fixing an optical fiber cord. CONSTITUTION:A sheath 2 at the edge part of a plastic optical fiber cord is eliminated, thus exposing an optical coated fiber 3. A cap 4 is provided with a through hole 5 for inserting and fixing the edge part of the optical fiber cord, a taper 8 is formed at a tip port 7, and at the same time a bank-shaped protrusion 4a where the width of the top part is 0.3mm or less is formed at the end face. An adhesive 9 is applied to the coated fiber 3 and the edge part of the optical fiber cord is inserted from an insertion port 6. The sticking-out coated fiber 3 is cut by a blade 11. After the top part of the protrusion 4a is adhered to a mirror-surface plate 12, they are heated by a heater 13 and the tip part of the coated fiber 3 facing the tip part 7 is melted. Since the taper 8 is formed at the tip port 7, the melted coated fiber 3 is expanded into the tape 8. Finally, the mirror-surface plate 12 is cooled, thus hardening an end face 14 of the coated fiber.
