摘要： An optical connector including a ferrule, an outer housing, and a latch is disclosed. The ferrule holds an optical fiber at a front end of the optical connector. The outer housing is located closer to a rear end of the optical connector than the ferrule. The latch is connected to the outer housing and extends from a proximal end toward the front end of the optical connector. The latch includes an engaging part to engage with an external device at a distal end thereof. The latch is configured such that the engaging part is pushed down toward the ferrule. The engaging part includes an engaging main body and an engaging protrusion protruding outwardly from the engaging main body. The engaging protrusion includes an engaging surface to engage with the external device at a rear of the engaging protrusion, and an edge of the engaging surface is chamfered.

摘要： An optical connector including a housing body having a ferrule, an outer housing, a latch, and a tab is disclosed. The latch extends from a proximal end toward a front end of the optical connector and includes an engaging part at a distal end. The tab is placed on an outer side of the latch, movable with respect to the outer housing, and pushes down the engaging part toward the housing body according to movement of the tab. The distal end of the latch floats to space apart from the housing body. A first protrusion is disposed on an inner side of the tab. The optical connector is configured to contact an inner side of the latch with the first protrusion to push down the engaging part toward the housing body with the first protrusion as a fulcrum when the engaging part is engaged with the external device.
