The first connector module includes a first carrier and two first connectors which are fixed to the first carrier. The second connector module includes a second carrier and two second connectors which are fixed to the second carrier. The second connectors are respectively and detachably connected to the first connectors. The connection assistance module includes a rotatable component and an assembled component respectively disposed on the first carrier and the second carrier. The rotatable component has an inclined surface, and the assembled component has an engaging portion. When the rotatable component is rotated, the engaging portion is guided by the inclined surface so that the first carrier is moved toward or away from the second carrier, allowing the first connectors to be detachably connected to the second connectors.
