定の接触圧力で相互に接続される。 Since the present invention has the above configuration, when connecting the optical fiber cables 10 using the optical connector 1, the operating portion 11a of the engaging members 11, 11 is placed inside the connector, that is, the first The fastening portion 11b is pushed in the direction of the arrow C in the figure, and the fastening portion 11b is moved backward in the C direction against the elasticity of the member 11. Since the slit 11d is formed in the member 11, the operating portion 11a
The fastening portion 11b can be easily retreated in the C direction by pressing in the C direction. In this state, connect the connector 1 to one entrance 12a of the adapter 12.
Insert the main body 7 until the tip 7b abuts the side surface 13c of the abutting block 13, and then press the operating part 11a.
Release the pressure. Then, the operating part 11a projects outward from the connector, that is, in the direction of arrow D, together with the fastening part 11b, due to the elasticity of the member 11, and the fastening part 11b fits into the fastening groove 12b, and the connector 1 is fastened to the adapter 12. On the other hand, the fiber alignment member 2 is inserted onto the abutting block 13, and is positioned by being pressed against the abutting surfaces 13a, 13b of the block 13 by pushers 15A, 15B. In this way, both inlet portions 12a, 12 of the adapter 12
When the connectors 1 are inserted into the connectors a, the connection surfaces 2b on which the optical fiber end surfaces of the alignment member 2 are arranged are as follows.
They abut each other in block 13. At this time, a pressing force in the direction B acts on the member 2 through the connecting surface 2b, and the member 2 moves the claw 11 into the main body 7.
It moves in direction B against the elasticity of c. Then, as a reaction from the claw 11c, the member 2 is pressed with a predetermined pressure in the direction A, that is, in the direction of the connection surface 2b, and the optical fiber end surfaces of the connection surface 2b of each connector 1 are connected to each other with a constant contact pressure.
