The upper part has side plate receiving grooves on both sides, with cover plates on the inner sides of these grooves. The lower part has a bottom plate with side plates on both sides, each with an external heat dissipation vent and a cover plate receiving groove at its top. The bottom plate has a partition slot in its center, with a partition plate fixed to it. Mounting holes are located on both sides of the partition slot, and the partition plate has an internal heat dissipation vent. A bracket is provided on the top surface of the bottom plate. This device, when installing cables, does not conveniently restrict the position of the cables within the trough-type cable tray, hindering the orderly installation of cables and reducing the efficiency and practicality of the cable tray.
