[0002] When laying optical cables, a large margin needs to be reserved at the node positions. Currently, most of the excess wires are directly wound and fixed on the poles. Exposure to the sun and rain can easily cause the insulation layer to stick or bend, which in turn leads to line failures. In the prior art, there are excess wire boxes for collecting excess wires. For example, the utility model patent with patent number 201320007865.1 discloses a excess wire box, in which horizontal beams, vertical beams and excess cable racks are arranged in the box. The excess wires of the optical cable are spirally wound and fixed to the box through fasteners. The excess wire box of the optical cable only places the excess wires originally wound and fixed on the poles in a box. The circles of the excess wires are still in contact with each other, which can easily cause the insulation layer to stick.

The beneficial effects of the utility model are: the surplus wire is separated by the positioning column and placed in the box body, so as to prevent the aging insulation layer of the optical cable from sticking; the structure is reasonable and the operation is simple and convenient.

[0004] However, the above components are installed at the upper end of the cable rack, which is not convenient for staff to inspect and maintain, so maintenance is required. Utility Model Content
