The present invention relates to a cable tray connecting device. The objective of the present invention is to provide a cable tray connecting device capable of installing a fire structure to prevent transfer of a fire. Another objective of the present invention is to provide a cable tray connecting device capable of electrically connecting an upper cable tray and a lower cable tray while the fire structure is installed. To that end, the cable tray connecting device includes: a main body which includes a pair of wide walls and a pair of narrow walls facing each other and an upper opening and a lower opening connected in the vertical direction; a pair of upper extension members which are rotatable around a moving axis line, which is in parallel with the pair of the narrow walls, from the upper opening and moves between an opening position extended in the vertical direction and a closing position extended in the horizontal direction; and a fire cover which blocks the upper opening using a cable passing area through which a cable can pass in the vertical direction when the upper extension members are at the opening position. |
