Patent number: 9256035Abstract: Disclosed is an optical fiber connector. The connector includes a ferrule optical fiber enclosed in a ferrule, the ferrule being elastically supported by an elastic member; and a main optical fiber. The ferrule optical fiber and the main optical fiber are fusion-spliced by a fusion splice unit. A fusion splice part is reinforced by a reinforcing sleeve and the ferrule optical fiber being integral by the reinforcing sleeve moves within a stopper.Type: GrantFiled: January 14, 2015Date of Patent: February 9, 2016Assignee: ILSIN OTS CO., LTD.Inventors: Chan Soul Park, Kwang Cheon Lee, Sang Chul Jun, Jun Young Park

Patent number: 9057849Abstract: The present invention relates to an optical fiber connector whereby an operator can easily couple optical fibers on site, and to an assembly method for the same. More specifically the invention relates to: an optical fiber connector wherein a guide ferrule bush is provided between a ferrule and a coil spring so as to be able to solve a problem whereby a ferrule optical fiber between a ferrule body and a reinforcing sleeve is bent, and a problem whereby contact between the ferrule body and the ferrule optical fiber is broken due to frequent movement, when the ferrule moves within a range of movement provided for by a resilient member due to the resilient member; and to an assembly method for the same.Type: GrantFiled: August 25, 2010Date of Patent: June 16, 2015Assignee: ILSIN OTS CO., LTD.Inventors: Chan Soul Park, Kwang Cheon Lee, Sang Chul Jun, Jun Young Park

Patent number: 8509587Abstract: A portable optical fiber processing apparatus is disclosed. The portable optical fiber processing apparatus of the present invention includes a base (1), which provides a space in which components are installed, and a sheathing stripping unit (10), which is provided on the base and strips sheathing from an optical fiber (R). The apparatus further includes an optical fiber cutting unit (40), which is provided on the base and cuts a portion of the optical fiber, from which the sheathing has been stripped, using a sliding cutter (43) in a direction perpendicular to the longitudinal direction of the optical fiber, and a welding unit (50), which is provided on the base and welds junction portions of two optical fibers. The present invention is characterized in that a process of stripping sheathing from an optical fiber and cutting, cleaning and welding processes can be conducted using a single apparatus.Type: GrantFiled: November 15, 2011Date of Patent: August 13, 2013Assignee: Ilsin Tech. Co., Ltd.Inventors: Jae Seop Song, Sang Chul Jun, Young Bae Seo
