Abstract
To provide an optical connector which can slidably and stably support the optical connector element (ferrule) within the connector housing without increasing the axial length of the ferrule, the optical connector plug comprising: (a) a plug housing (202) formed with a shoulder portion (253) between a large hollow portion (254) and a small hollow portion (252) and formed with no projection between said two portions; (b) a plug ferrule (201) connected to an optical fiber (204) and formed with a flange portion (201b) slidably fitted into the large hollow portion of said plug housing and an end portion (201a) passed through the small hollow portion of said plug housing; and (c) a spring (203) housed within said plug housing to urge the flange portion of said plug ferrule against the shoulder portion (253) of said plug housing. A mated jack ferrule (201) is fitted to the small hollow portion (252) of said plug housing (202) via a sleeve holder (206) having a floating slit sleeve (205) therewithin so as to absorb an axial dimensional fitting error between the plug ferrule and the jack ferrule by axially urging the flange portion (201b) of said plug ferrule by an inner end of the sleeve h…
