も結合できるので結合の自由度も大きい利点がある。(Effects of the Invention) As explained above, the optical connector of the present invention includes two alignment sleeves in the adapter, two ferrules in the plug, and the locking claws of the elastic locking piece of the adapter and the four parts of the plug. Since the connection is guaranteed by the locking of the fibers, it is now possible to connect with one adapter, compared to the conventional method that required two adapters to connect two optical fibers. The mounting area of the adapter is small, which has the advantage of allowing high-density mounting of optical connectors. Further, since both the adapter and the plug include two alignment sleeves and two ferrules in one housing, there is an advantage that the number of parts in the housing can be reduced and economy can be achieved. Furthermore, since a single-core optical connector having only one ferrule in the plug can be coupled, there is an advantage that there is a large degree of freedom in coupling.
