An optical ferrule is disclosed in which a concave portionhaving a gate G in resin molding disposed therein is formed in a ferrule body. According to this constitution, it is possible to easily cut a flashleft after a gate of the concave portionof the ferrule bodyis cut after molding with a gate cutter, so that, when the ferrule bodyis fitted in a housing of an MPO connector and the like, the problem that the flashprotrudes from the concave portionand the flashhitching to an inner wall of the housing dose not occur. Accordingly, the labor required for removing the flashby polishing can be eliminated, and hence productivity of the ferrule bodycan be improved. Thus, a large number of ferrule bodiescan be automatically manufactured without requiring much manpower.

Optical connector

Development of a multiple-core optical connector which can make multiple-core or a plurality of optical fibers connected in a simple manner has been sought. There are provided an optical connector ferrule for internally fixing beforehand the optical fibers arranged in parallel on an identical plane and having joining end surface of a tip which is polished, and an optical connector which is furnished with a connecting mechanism for maintaining a connected state by holding aforementioned optical connector which protrudes from the rear end, facing the aforementioned joining end surface of the aforementioned connector ferrule and a separate optical fiber connected by abutting against the optical fiber of the optical connector ferrule side.

An optical connector is provided where an biasing device,which biases a ferrule,having an optical fiber,secured thereinside and a tip end face,which has been polished, in a tip end face,direction, is located to the rear of a connection mechanism,for connecting the optical fiber,on the ferrule,side and a separately inserted optical fiber,at a rear end side of the ferrule,opposite to the front end face,The connection mechanism,has a construction which uses a mechanical splice, and is opened and closed by a release member inserted into an insertion opening,which is opened along an alignment axis direction. Hence the opening and closing operation does not interfere with the biasing device,so that operability is improved. Moreover, for this type optical connector there is provided an optical connector housing,which accommodates the ferrule. With this optical connector housing,by merely inserting the ferrule, the connection mechanism,for connecting the pair for optical fibers at the rear end side of the ferrule, and the stop ring,accommodating the connection mechanism,then assembly can be simply performed so that workability in assembling the optical connector is improved.
