AI Technical Summary

Technical Problem

Existing cable tray assemblies face stress concentration and potential damage when supporting heavy weights, leading to side wall and joining plate damage, and require lengthy assembly times due to multiple screw fixings.

Method used

A cable tray assembly design where the joining plate is press-fit between the upper and lower wings of the side walls, with longitudinal ribs and grooves, forming a compact body that distributes weight evenly and prevents bending, and includes optional screw fixation for added security.

Benefits of technology

The design enhances the cable tray's weight-bearing capacity without damaging the side walls or joining plate, simplifies assembly, and maintains cost-effectiveness by using a single-piece joining plate with polymer materials, ensuring robust and efficient cable management.

Abstract

1. The present invention relates to a cable tray assembly comprising two cable tray segments (1) and a joining plate (9) made up of a single part, which is coupled to two contiguous side walls (26) of the two cable tray segments (1) for joining them. The joining plate (9) has two longitudinal edges which rest on an upper wing (6) and a lower wing (7) of the two walls (26), such that it is press fit between said wings (6, 7). A web of the walls (26) has an outer face (11) with a longitudinal rib (12). The joining plate (9) has a planar face which rests on the outer face (11) and comprises a longitudinal groove fitting in the rib (12).
