Patent number: 8506174Abstract: An optical connector includes a second operation lever extending rearward from a first operation lever. By pressing a rear end portion of the second operation lever up, or pressing the second operation lever forward, the first operation lever can be inclined forward. In this way, a front end portion of the first operation lever presses a rear end portion of a locking lever down, and disengages the locking lever and an optical adapter from each other. Thus, the optical connector can be detached from the optical adapter.Type: GrantFiled: June 1, 2011Date of Patent: August 13, 2013Assignee: Suncall CorporationInventor: Masaya Nakagawa

Patent number: 8317408Abstract: Provided is an optical-fiber connection unit in which a split sleeve (14) for performing centering of distal end portions of ferrules (11 and 111) is provided not to an optical adapter (20) but to an optical connector (10). With this configuration, it is unnecessary to provide a sleeve holder inside a casing (21) of the optical adapter (20), and hence a shape of the optical adapter (20) is simplified. Further, a sleeve holder (13) provided to the optical connector (10) is formed in a state of being exposed outward. Thus, a risk of defective molding is reduced, and presence or absence of defective molding can be easily confirmed.Type: GrantFiled: September 13, 2010Date of Patent: November 27, 2012Assignee: Suncall CorporationInventor: Masaya Nakagawa
