摘要： In an optical connector structured having an optical connector ferrule accommodated in a housing urged towards the butt connection direction by an urging means, a technology is developed wherein the application of an external sideways force to the optical connector ferrule in a connected state is prevented, and the connected state is stably maintained. An optical connector 20 is provided wherein a positioning support part 24 which accommodates and supports a freely detachably a stop guard 26, which projects from the optical fiber ferrule 2, is provided in a housing 21; when this optical connector ferrule 2 is moved towards the butt connection direction, the stop guard is accommodated in the positioning support part 24 and positioned and supported; and when this stop guard 26 is released from the positioning support part 24, floating of the optical connector ferrule 2 in the housing 2 is permitted. Thereby, even if a sideways pressure is applied to the housing 21, a displacing force is not applied to the optical connector ferrule 2, and the butt connection state with the other optical connector ferrule is not affected.

The connection mechanism 25 has a construction which uses a mechanical splice, and is opened and closed by a release member inserted into an insertion opening 39 which is opened along an alignment axis direction. Hence the opening and closing operation does not interfere with the biasing device 26, so that operability is improved. Moreover, for this type optical connector there is provided an optical connector housing 21 which accommodates the ferrule. With this optical connector housing 21, by merely inserting the ferrule, the connection mechanism 25 for connecting the pair for optical fibers at the rear end side of the ferrule, and the stop ring 27 accommodating the connection mechanism 25, then assembly can be simply performed so that workability in assembling the optical connector is improved.
