- the cutout fitting 35 of the frame 39 and the cutout 36 of the frame 10 are omitted. Can also.
- connection pairing ensure that the optical connectors of each connection pair of the first connector group 3 and the second connector group 4 are connected securely (connection pairing). In order to make sure that there is no difference), it is preferable that the adapter 8 and the first and second plugs 5, 6 are marked in some way so that there is no mistake in the connection pair.
- the claw portion 25 of the stopper 24 is locked in the claw fitting hole 26 formed in the frame 10 of the first and second plugs 5 and 6. Accordingly, the first and second optical connector groups 3 and 4 are retained and locked in the connector insertion holes 18 and 19 of the first and second plugs 5 and 6, respectively.
- the connector locking means for locking the second optical connector groups 3 and 4 into the connector insertion holes 18 and 19 is not necessarily a horn, and the ° 24 is a frame. Not necessarily to those of the configuration in which the locking to 1 0.
- the first and second plugs 5 and 6 have the frame 10, the slider 9, and the boot 11, but the first and second plugs are sliders. 9 and the boot 11 may be omitted.
- a housing such as a slider 9 is provided to accommodate the frame 10, and a boot 11 is provided to provide the multi-core fibers 43 of the first and second optical connector groups 3 and 4. By storing them together, the first and second optical connector groups 3 and 4 can be very easily handled.
- the claw portion 15 of the adapter 8 and the claw portion 16 of the first and second plugs 5 and 6 are connected to each other.
- the adapter 8 and the first and second plugs 5 and 6 are detachably connected to each other by the fitting of the adapter 8, but the adapter 8 and the first and second plugs 5 are connected by any other appropriate method. , 6 can also be connected.
- the number of optical fibers and the number and size of the optical connectors of the first and second optical connector groups 3 and 4 connected by the collective connection structure of a plurality of optical connectors of the present invention are not particularly limited. is not. Industrial applicability
- the collective connection structure of a plurality of optical connectors and the optical connector arrangement and the adapter according to the present invention can easily connect a plurality of multi-core optical connectors of an optical fiber terminal such as an optical cable in an optical communication field or the like. Suitable for quick, high-precision batch connection.
