Patent number: 6869228Abstract: The ferrule of the present invention comprises a ferrule main body including an insert pipe defining an outer circumferential surface of the ferrule main body and a molded plastic member disposed inside the insert pipe integrally therewith and having an optical fiber receiving bore in an axial center thereof; and a tubular base portion molded onto a rear end of the ferrule main body. Because the outer diameter of the ferrule main body is defined by the insert pipe, the rigidity, circularity and dimensional precision of the outer diameter can be improved. Because the base portion is molded separately from the ferrule main body, the manufacturing process can be simplified and the production cost can be reduced.Type: GrantFiled: December 3, 2002Date of Patent: March 22, 2005Assignee: Kabushiki Kaisha Act OneInventors: Kiyoshi Ishii, Kenichi Mitani, Masumi Okajima, Masafumi Okuma
