The present invention relates to an aluminum cable tray. Each connector (20) is closely in contact with internal surfaces of two side rails (10) which face each other as being separated apart from each other at the same time, so each guide protrusion (13) of the two side rails (10), which face each other as being separated apart from each other while a plurality of lattice links (21) protrude through a plurality of lattice grooves (11) of the two side rails (10) which face each other as being separated apart from each other, is inserted into guide grooves (22) of each connector (20) at the same time. As an interval between the two side rails (10) which face each other as being separated apart from each other is changed, each guide protrusion (13) of the two side rails (10) which face each other as being separated apart from each other is slid in the guide grooves (22) of each connector (20). When the aluminum cable tray is installed in an environment where a temperature change is severe, a phenomenon that a connection area between the side rails is bent can be prevented. |
