Publication number: 20180088288Abstract: In a duplex optical connector plug 10A, when one of first and second optical connector assemblies 11a, 11b is rotated around its axis in a clockwise direction or a counterclockwise direction, a rotational force of one of first and second gears is transmitted to the other of the gears by an intermediate gear. Thereby, interlockingly with the one of the optical connector assemblies 11a, 11b, the other of the optical connector assemblies 11a, 11b is rotated around its axis in the clockwise direction or the counterclockwise direction which is the same direction as the optical connector assemblies 11a, 11b.Type: ApplicationFiled: December 1, 2017Publication date: March 29, 2018Inventors: Junji Taira, Masayuki Jibiki, Yohei Takaishi, Norimasa Arai

Patent number: 9366827Abstract: An optical connector assembly and an optical connector adapter with a shutter each provide better heat radiation performance by blocking light outputted from a first optical fiber held by a first optical connector plug with a shutter thereby controlling temperature of an adapter body of the optical connector adapter not to exceed a prescribed level even when light having optical high power is outputted from the first optical fiber for about 15 minutes. An countermeasure against the light having optical high power is provided in a side wall of one of first and second receiving holes to be irradiated with the light outputted from the first optical fiber toward the second receiving hole and reflected thereafter by the shutter plate disposed in one of the first and second receiving holes.Type: GrantFiled: August 31, 2015Date of Patent: June 14, 2016Assignee: SEIKOH GIKEN CO., LTD.Inventors: Junji Taira, Masayuki Jibiki, Yohei Takaishi

Patent number: 8936400Abstract: A shutter member of the optical communication adapter includes a base plate, both side plates, a connecting plate, and an elastically deformable shutter plate having a predetermined curvature radius. In the adapter, the base plate of the shutter member is fitted into a bottom recess formed on an external surface of a bottom wall and the both side plates of the shutter member are fitted into both side recesses formed on the external surface of both sidewalls. The shutter plate of the shutter member is positioned at both open ends of an insertion hole to shield the insertion hole while being curved to form a convex shape toward a center portion of the insertion hole and, when a connector is inserted into the insertion hole, falls toward the center portion of the insertion hole by being pressed by the connector.Type: GrantFiled: January 28, 2014Date of Patent: January 20, 2015Assignee: Seikoh Giken Co., Ltd.Inventors: Masayuki Jibiki, Junji Taira
