Expanded cable tray structure

Abstract

An expandable cable tray structure includes a first component and a second component. The first component has a first bottom wall and a first side wall orthogonally connected to the first bottom wall. The second component has a second bottom wall and a second side wall orthogonally connected to the second bottom wall. The first bottom wall has a first step portion, and the second bottom wall has a second step portion. The first step portion directly or indirectly joins with the second step portion, such that the first bottom wall and the second bottom wall form an integrated cable tray bottom wall, and the surface of the cable tray bottom wall near the first and second side walls is a flat surface. Thus, the expanded cable tray structure of this invention allows for changes or expansion of the cable tray width according to the number of wires, reducing manufacturing and warehousing costs, and the integrated cable tray bottom wall has high reliability.
