In a structure in which racks back-to-back with each other are placed on a floor, a bottom of at least one of the racks is pressed against the floor by a connecting bar crossing the bottom. In a structure in which a cover is mounted on a rack, a cover has a first shaft movable in a direction parallel to the first shaft and the cover is mounted on the rack by using the first shaft. In a structure in which a cable rack is mounted on a top surface of a rack, a plurality of engagement screws provided on the cable rack are driven into holes formed on the top surface of the rack so that the cable rack is mounted on the top surface of the rack.

Structure of rack

A shelf assembly in an electronic switching system in which storability of a cable and coolability of the assembly are enhanced. The shelf assembly comprises an upper stationary rail firmly secured to an upper member of the shelf, an upper slide rail slidably mounted on the upper stationary rail, a lower stationary rail firmly secured to a bottom member of the shelf, and a slide rail slidably mounted on the lower stationary rail. The shelf assembly further comprises a cable box firmly secured to the upper and lower slide rails, the cable box having a plate spreading vertically, an area for receiving the cable being defined in one side surface of the vertical plate; and a drawer unit removably inserted in the cable box along the other side surface of the vertical plate, the drawer unit having a plurality of per-line packages which are withdrawably inserted in the drawer unit, the per-line packages each storing the contents of service per subscriber. A common unit is withdrawably inserted in the shelf, and a cable for electrically connecting the common unit to the drawer unit extends so far as to a front end of the vertical plate of the cable box along the one side surface of the vertical plate.
