## Abstract

The invention relates to a section of cable tray, which can be connected to other sections without using additional accessories, allowing the connection of anchoring elements located at one end of the walls of each tray section. The aforementioned anchoring elements take the form of rods bent to form a V-shape that extends into straight extensions which are installed between longitudinal rods. In addition, turns are provided in the aforementioned rods between the straight zones and the V-shape, one turn towards the interior of the tray and another turn towards the exterior. Sections are coupled by sliding the sides of the first transverse rod of the tray section to be joined through the V-shape, such that they remain trapped between the inner turns and the sides of the last transverse rod of the receiving tray section.

## Claims

### Claim 1

Cable tray section, made of longitudinal and transversal metal wires in a “U” shape forming a channel with a base and side walls, characterised by having at least one anchorage element (1, 1′) made up of a metal wire bent into two parts with a “”V″ shape (2, 2′) at one of its ends, followed by bends (4, 4′) and (3, 3′), and then followed by parallel straight sections (5, 5′).

### Claim 2 (depends on 1)

Cable tray section, in accordance with claim 1, characterised because each anchorage element (1, 1′) is installed between the longitudinal metal wires (7, 8), on the outer walls of one end of each tray section.

### Claim 3 (depends on 1)

Cable tray section, in accordance with claim 1, characterised because the anchorage element (1, 1′) is welded to the last but one (9) and last (10) transversal metal wires on the straight sections (5, 5′), protruding the straight sections (5, 5′) of the last transversal metal wire (10), in order to leave a gap (11, 11′) between the side of the last transversal metal wire (10, 10′) and the bend (3, 3′) on the anchorage element (1, 1′).

### Claim 4

Cable tray section, in accordance with the previous claim, characterised because the length of the gap (11, 11′) is related to the thickness of the transversal metal wire.

### Claim 5 (depends on 1)

Cable tray section, in accordance with claim 1, characterised because the bend (3, 3′) on each anchorage element (1, 1′), located after the straight section (5, 5′), faces the inside of the tray, and the bend that follows (4, 4′), before the “”V″ shape (2, 2′), faces the outside of the tray.

### Claim 6 (depends on 1)

Cable tray section, in accordance with claim 1, characterised because the vertex of the “V” shape (2, 2′) is flattened (6) and has an extension and an angle suitable for being placed in the “V” shape (2, 2′) between the two longitudinal metal wires on the tray section walls.
