  • Optical fiber holder, optical fiber adapter, and optical fiber processing device having a positioning mechanism
    Patent number: 7502542
    Abstract: Guiding rails (22) are formed along both the edge portions of a back surface (21) of an optical fiber holder (20), which guide positioning protrusions (12) formed on a mounting surface (110) in an optical fiber processing device (10). The interval between inner-wall surfaces (23) of the guiding rails (22) opposed to each other corresponds to the interval between the positioning protrusions (12). Hollow portions (24) are formed at the back surface (21) of the holder (20), into which the positioning protrusions (12) are inserted. The holder (20) is tightly fixed on the mounting surface (11) of the device (10).

  • Optical fiber locking device for fusion splicing
    Patent number: 6731854
    Abstract: An optical fiber locking device is provided with a holder base, a table for support of an optical fiber, the table being fitted to the holder base and provided with a magnet and a slit, an openable and closable cover, being connected to the table by a hinge and detachably attached by the magnet and a sliding arm including a finger protruding out from the slit so as to operate the cover and a grip, and movably fitted to the holder base. When the grip is driven to a direction of the cover so as to drive the finger, the finger pushes the magnetically attached cover up so as to be opened.
