Patent number: 8858091Abstract: Provided is an optical connector whose miniaturization is easier than conventional. An optical connector (100) comprises a housing (103) holding an optical member (101), a slider (105) slidably held by the housing (103), a shutter (107) provided to the slider (105) in an openable and closable manner and adapted to be opened and closed to expose and isolate the optical member (101) to and from the outside, and slider-side coil springs (109) pushing the slider (105) in a direction away from the housing (103). The slider-side coil springs (109) are disposed in a width direction of the shutter (107). The optical connector (100) is configured such that the shutter (107) is closed when the slider (105) is moved by an elastic force of the slider-side coil springs (109) in the direction (direction A1) away from the housing (103) and that the shutter (107) is opened when the slider (105) is moved against the elastic force of the slider-side coil springs (109) in a direction approaching the housing (103).Type: GrantFiled: January 5, 2012Date of Patent: October 14, 2014Assignee: Japan Aviation Electronics Industry, LimitedInventors: Yuichi Koreeda, Takayoshi Yamauchi, Osamu Hashiguchi, Naoki Katagiyama

Patent number: 8025511Abstract: A connector is matable with a mating connector. The connector has a contact, a housing, a sliding shell, at least one engagement portion and at least one disengagement portion. The housing holds the contact. The sliding shell covers, at least in part, the contact and the housing. The sliding shell is held on the housing so as to be movable between a mating position and a protective position. The connector is mated with the mating connector when the sliding shell is positioned at the mating position. The sliding shell is laid, at least in part, beyond a front end of the housing when the sliding shell is positioned at the protective position. The at least one engagement portion is configured to engage with the sliding shell located at the protective position so as to prevent the sliding shell from moving toward the mating position.Type: GrantFiled: October 15, 2010Date of Patent: September 27, 2011Assignee: Japan Aviation Electronics Industry, LimitedInventors: Shuichi Aihara, Takayoshi Yamauchi
