Various embodiments of the present disclosure are directed to cable trays for carrying cables. In one such embodiment, a cable tray made of wire material is disclosed with a number of lateral U-bent wires and longitudinal wires fastened thereto. The U-bent wires form a bottom and a first and a second side wall for the cable tray, where the bottom is narrower than the side walls are high, as such the cables may be placed stacked one above another in the cable tray. The first side wall is made with a wavy shape with wave troughs placed close to or in contact with the second side wall and wave crests between the wave troughs. The wave-shaped first side wall forms, together with the second side wall, spaces for receiving cables.

The present invention relates to a cable tray section which allows being successively coupled to another tray section (1) having similar features, without needing accessories or angle requirements on the horizontal plane, comprising longitudinal metal wires (10); U-shaped transverse metal wires (20); at least one anchoring element (30) installed between the longitudinal wires (10), attached to the last and next to last transverse wires (20), and comprising a single metal wire (31) close to the next to last transverse wire (20); and a pair of straight sections (32, 32′) parallel to one another; where the upper straight section (32′) projects with respect to the last transverse wire (20), forming an S-shaped section (33) perpendicular to the straight sections (32, 32′), such that there is established a free space (40) between the last transverse wire (20) and said S-shaped section (33); said space (40) having a dimension corresponding to the thickness of a transverse wire (20).

A cable support apparatus includes first and second horizontal supports spaced-apart and substantially parallel to one another, a plurality of vertical supports spaced-apart horizontally along the first and second horizontal supports, and at least one junction box assembly configured to hang from the first horizontal support. Each horizontal support is formed from wire stock. Each vertical support is formed from wire stock and secured to each of the first and second horizontal supports. At least two of the vertical supports include cable-receiving segments that cooperate to define at least one cable-receiving channel extending horizontally. The at least one junction box assembly includes an input and an output for receiving cable ends of cables disposed within one of the at least one cable-receiving channels to enable joining of the cable ends within the junction box assembly.

A cable tray system including two or more cable tray sections comprising a first side rail and a second side rail arranged substantially parallel to one another and a floor extending between. The tray system also includes one or more flex-wires for joining the cable tray sections, where the flex-wires can be U- or loop-shaped. Upon exerting tension on the flex-wires, the first and second cable tray sections can move away from one another from a first position to a second position. In addition, the tray system includes a fastening device that removably locks the tray system into the second position.

A splice for connecting a first and second cable tray includes first and second connectors. The first connector has a first base, a first tine extending from the first base having a first female connecting feature, and a second tine extend from the first base having a first male connecting feature. The first and second tine are separated by a first opening. The second connector has a second base, a third tine extending from the second base having a second female connecting feature, and a fourth tine extend from the second base having a second male connecting feature. The third tine and the fourth tine are separated by a second opening. The first and second connectors are configured to be connected together with the first female connecting feature mating with the second male connecting feature and the first male connecting feature mating with the second female connecting feature.

A connection device connects mesh cable trays and mesh cable tray section. The trays include longitudinal and transverse rods joined together. The connection device includes two side parts connected by a central connection section. The central connection section includes an intermediate section and two grooved sections. Each grooved section is disposed on one side of the intermediate section. The height of the central connection piece is greater than the distance between two consecutive longitudinal rods of the cable. The central connection piece has s recess for housing a longitudinal rod of the cable tray. One grooved section has an outer side surface with a wedge-shaped upper section, a central section wherefrom a connection device side part projects laterally, and a lower section below the recess housing the longitudinal rod. The other grooved section projects laterally from the other side part, connecting the side part and the other grooved section.

The present invention is directed to a cable routing system with a bracket that joins adjacent cable trays. The bracket includes a main body having a top edge, a bottom edge, and sides. The top edge includes at least one notch at a center of the main body to retain transverse wires of the adjacent cable trays. The bottom edge includes a spring arm to hold the bracket in place. The bracket is attached to adjacent cable trays with a longitudinal wire of each cable tray positioned between the top edge and the spring arm to secure the bracket to the cable tray.

A barrier strip for a cable tray of the type including longitudinal wires and lateral wires interconnecting the longitudinal wires includes a vertical wall extending along a length of the barrier strip. A tray coupler is below the vertical wall. The tray coupler couples to one or more of the longitudinal and lateral wires of the cable tray without the use of additional fasteners.
