However, in the case of this invention, the locking mechanism such as the screw 21 is removed and the bobbin 2 is removed.
By rotating it 45 degrees, you can move the back part to the side and perform the above processing operations.

As mentioned above, the optical fiber junction box of this invention is designed so that the extra length processing bobbin can be rotated around the stay within a certain rotation angle range. This has the effect of making it easier to work on the back side of the bobbin, which has been difficult to process due to the lack of sufficient clearance. Also,
As a result, since the core fiber is not subjected to excessive bending, etc., it is possible to eliminate problems such as performance deterioration and wire breakage, and it is also possible to shorten the working time for processing surplus length.
