The invention discloses a vertically-placed storage container for prefabricated connecting wires and belongs to the field of storage containers. On the basis of a frame type storage container, one or more vertical partition plates are arranged for dividing the three-dimensional storage space into two or more vertical storage spaces, and the position of the partition plates can be freely adjusted for adjusting the storage space of each internal partition in the storage container according to the size of a single wire. The storage container can be folded and stacked, the requirements of manual operation and automatic operation for the universality and the modularity of storage equipment are met, convenience is brought to the manual operation, the intensity of the manual operation is lowered, and standardized operation of warehouses can be realized. The storage container can be widely used in the storage and management field of specified-length cables and scattered cables.
