Patent number: 7637673Abstract: A straight type optical connector enables a splicing operation of an optical fiber cable accurately and stably without requiring skilled labor and having a superior on-site installation property. An optical connector is provided with a splicing section for securely supporting an incorporated optical fiber securely supported at a ferrule and an optical fiber of an outside optical fiber cable in an end-abutting condition. The body of the optical connector is provided with a cable holding member able to hold an optical fiber cable. The cable holding member can be set at a temporary position where it makes an optical fiber of the optical fiber cable abut against the incorporated optical fiber at the splicing section in the state holding the optical fiber cable and bends a covered optical fiber of the optical fiber cable between the splicing section and the cable holding member by a pressing force in the lengthwise direction.Type: GrantFiled: June 23, 2005Date of Patent: December 29, 2009Assignees: 3M Innovative Properties Company, Nippon Telegraph and Telephone CorporationInventors: Tomayasu Oike, Takaya Yamauchi, Akihiko Yazaki, Tsunetaka Ema, Kenichi Nakazawa, Yasuhiko Hoshino
