The holder is designed for a specific cable size, which creates inconvenience when working with a cable of various sizes, this design is difficult to manufacture and operate, low-tech.

According to the utility model certificate No. 29412 (publ. 10.05.03), the cable tray is free from this drawback, containing a base, insulating elements movably fixed along its longitudinal axis, interacting with the base groove and fixing bolts installed in the insulating elements, each insulating the element is made in the form of a parallelepiped, in two opposite planes in its middle part grooves of a trapezoidal shape are made with the upper base to the center of the parallelepiped, the insulating element can be made using materials of various colors, as well as with a fluorescent coating.

The tray of this design is very metal-intensive, has a lot of weight.

Known tray for cable laying according to the certificate for utility model No. 28659 (publ. 03/27/2003), containing ribs installed perpendicular to one another with the formation of a lattice and attachment nodes, and the ribs are made of rods, and the ribs of the base are made in a U-shape, nodes the fasteners are made of brackets fixed in pairs at the intersection of the ribs, and the brackets are fixed with a turn of one relative to another 180 °.

When operating the trays of this design, the following disadvantages were identified: inconvenience if cable replacement is necessary, because the cable gets mixed up during operation.

The device according to US patent No. 5435507 (publ. March 17, 1994) is known, which is easily mounted and has ample opportunities for fastening a cable of various sizes.

The fixture is designed for one cable, bulky.

The present invention solves the problem of creating a device that is convenient to manufacture, does not require additional design and costs when attaching to the surface of various reliefs, designed to attach a large number of cables, convenient for laying, operating and replacing a damaged cable or replacing a cable with another size, convenient spatial fixation, simplification of wire installation technology and reduction of time when laying and replacing the cable.

To achieve the specified technical result in a device for attaching cables or tires containing a base, insulating elements and fixing bolts installed in the insulating elements, the insulating elements are attached to the base, made of a set of paired, parallel rods with a fastening element, which is pressed against the base moreover, the fastening element has profile bends of opposite edges, and the base of the insulating element and the fastening element are square in shape.

Distinctive features of the proposed device from the above is that the insulating elements are attached to the base, made of a set of paired parallel bars using a fastening element, which is pressed against the base, and the fastening element has profile bends of opposite edges, and the base of the insulating element and fixing The element is square.

The proposed design is illustrated by drawings, where

figure 1 shows a device for mounting the cable assembly;

figure 2 - fastening of the insulating element to the bracket;

figure 3 - bracket.

The device consists of a base 1 (1, 2), made of a set of pairs of support rods placed parallel to each other. The width of the device depends on the number of cables that are supposed to be mounted on them using insulating elements 2 (Fig. 2) made in the form of a parallelepiped, and in two opposite planes in the middle part of the insulating element grooves of a trapezoidal shape are made with the upper base to the center of the parallelepiped, necessary for cable mounts. The insulating element has a through hole for the bolt 4, located in the center of the base, which has a shape identical to the shape of the bracket 3 (figure 3). The bracket has profile bends of opposite edges. Profile bends of opposite edges are performed with a depth of not less than the diameter of the support rods. The base of the insulating element is square in shape.

The device is assembled directly in the room where you need to attach the cable. For this, the bar can be delivered in any form: pre-harvested of a certain length or in bays and cut into certain sizes in place, then the bars are attached (Fig. 1, 2) perpendicularly or at any angle to the supporting structures in pairs in parallel with the distance to the next "pair »Sufficient so that the cable does not sag due to gravity. The fastening of the rods to the supporting structures can be performed by any known method, at any angle to the support, and also the cable fastening devices can be interconnected in any combination. Also, the rods can be hung (figure 2) on the supporting structure, or floor structures can be formed. Then, insulating elements 2 are attached to the bases made of rods, on the one hand, which are “pressed” to the base by brackets 3, which have a through hole and profile bends of opposite edges in the center. The base of the insulating element is square in shape, the side of the base of the insulating element being equal to the side of the fastener which is square in shape. The insulating element is attached to the bracket, in the profile bends of which the supporting rods are placed using a bolted connection. The cable is laid between the insulating elements in the holes formed between them perpendicular to the support rods and the insulating elements are fixed with a bolt connection.

The number of insulating elements requires one more than the number of cables that need to be fixed. The insulating elements are connected to the bracket using a bolted connection.

The device, in comparison with wire trays, in which the ribs are made of rods, and the ribs of the base are made in a U-shape, does not have longitudinal rods, i.e. there is an exception of the element of the known device while maintaining the function of the excluded element, compared with the device according to US patent No. 5435507, the proposed device is designed to attach a large number of cables, has a simple structure, non-metal-intensive, i.e. The well-known problem is solved with the help of a new device for cable fastening, the technology of installation and dismantling of the device is simplified, and the time of installation and dismantling of the device is also reduced.

Installation of wire trays eliminates the use of a large number of components that are necessary for the installation of traditional steel trays. Changing the direction and level of the trays is made directly at the installation site using bolt clamps and brackets. The wire structure of the tray provides easy laying and fastening of any type of cable, and also allows you to quickly and at minimal cost to change and supplement the cable routing without dismantling and major alterations. The open structure provides better cooling of heavily loaded cables and their periodic inspection during operation.

In rooms where hygiene is very important, the minimum surface area of the device reduces the accumulation of dust and dirt.

The structure of the cable attachment device allows you to securely fix the cable. The fastening of the rods to the supporting structures can be performed by any known method, at any angle to the support, and the rods can be connected to each other in any combination.

This design of the cable fastening device allows easy and quick cable laying, taking into account the surface topography, laying cable of various sizes, creating any form of cable networks with branches, rounding, intersections, bends with a minimum number of components.

The device for attaching the cable can be installed on any surface: wall, floor, ceiling, horizontally or vertically, and it also makes it possible to place the cable in any plane, smoothly switch from one plane to another, efficiently and technologically lay cable lines along any surface, even despite the difficult terrain. Groups of cables of various brands, types and designs (for example, power cables and wiring) can be laid directly under each other, on the same base. The possibility of confusion between different cables (and, accordingly, cable groups) is excluded. In addition, it is easy enough to track the direction of laying of any cable lines and, if necessary, quickly and conveniently replace, dismantle or add the desired cable, for this, the insulating elements can be multi-colored, as well as with a fluorescent coating.

With this method of laying, all fire and technical safety rules and PUE are also observed. Cable lines are not adjacent to each other, which reduces their heating, and, thus, we can talk about an energy-saving component.

Using this device, you can build cable lines of any configuration at any distance from the surface (Fig.1, 2). When using this device, the reliability and convenience of cable fastening is increased, reliable cable fastening of various brands, type design and purpose (for example, power, computer, control circuits) is ensured, the complexity of installation works is reduced, the time of installation and dismantling of cable lines is reduced.
