る。The optical connector receptacle of the present invention is different from a structure in which an optical connector ferrule is incorporated in an optical connector plug and connected in an optical connector adapter, such as an MPO type optical connector, and the optical connector ferrules are directly connected to each other. It is a structure that can be connected inside and can be downsized. This enables mounting on a circuit board on which a module (laser module) mainly including an optical element such as a light emitting element such as a semiconductor laser (LD) or a light receiving element such as a photodiode is mounted. Also, by rotating the clip, you can easily switch the bias of the optical connector ferrule inserted from the ferrule insertion port to the optical connector ferrule on the optical device side, and release the bias, retract the clip from the ferrule insertion port and insert the ferrule. There is also an advantage that the connection workability and the connection switching workability can be improved, such that the optical connector ferrule can be freely inserted and pulled out from the ferrule insertion opening with respect to the housing simply by opening the mouth.

た優れた効果を奏する。As described above, according to the optical connector receptacle of the present invention, an optical connector ferrule is incorporated in an optical connector plug and connected in an optical connector adapter, such as an MPO type optical connector. In contrast, since the optical connector ferrules can be directly connected to each other in the housing, the size can be easily reduced. As a result, a module mainly including an optical element such as a light emitting element or a light receiving element (laser module)
It is also possible to mount on a circuit board on which is mounted. Also, despite its small size, the rotation of the clip allows you to easily switch the bias of the optical connector ferrule inserted from the ferrule insertion slot to the optical connector ferrule on the optical device side, and release the bias. It is possible to improve the connection workability and the connection switching workability by freely inserting and pulling out the optical connector ferrule from the ferrule insertion opening to the housing by simply retracting it and opening the ferrule insertion opening. .
