Abstract

An object of the present invention is to provide an assembly of cable trays capable of reducing a manufacturing cost by allowing a load to be reinforced and maintained simply by an L-shaped pin assembly structure when coupling cable trays with a connecting member. The assembly of cable trays includes a cable tray, a connecting member, and a fixing member. Meanwhile, the connecting member is configured to allow: a pair of protruding insertion pieces to be integrally formed at the upper and lower portions, respectively, in the middle thereof; the fixing member to be coupled with a slot formed by the protrusion of the protruding insertion piece; and a clip portion to be formed in an outer side direction of each of the protruding insertion pieces so as to be supported by the through hole of the cable tray.

Dependent claims

An assembly of cable trays, the assembly comprising:

a cable tray including a pair of side frames spaced apart from each other at a predetermined distance at left and right sides, respectively, the pair of side frames each having a plurality of through holes formed at opposite ends in the longitudinal direction thereof;
a connecting member interconnecting the side frames in order to arrange the cable trays in succession in the longitudinal direction;
and
a fixing member fixing the cable trays and the connecting member after the connecting member is allowed to be brought into close contact with the inner side of the cable trays,
wherein the connecting member is configured:
to form a pair of protruding insertion pieces integrally at the upper and lower portions, respectively, in the middle thereof;
to allow the fixing member to be coupled with a slot formed by a protrusion of the protruding insertion piece;
and to allow a clip portion to be formed in an outer side direction of each of the protruding insertion pieces, thereby being supported by the through hole of the cable tray.
