The body 1 of the tray is a cold-formed profile of pre-galvanized steel with a thickness of 0.5-1.5 mm with a cross section shown in FIG. 1.

The upper edge of each side wall of the housing 1 of the tray is bent, forming a groove 2 and a convex ledge 3 above it from the outside.

As can be seen in figure 1, the side 3 of the tray body is a surface of the type "corner with a rounding of the corner part with a radius of rounding of 1.5 mm and a free end bent into the body with a radius of rounding equal to the radius of the connecting rod 10 (Fig.7), which provides:

- lack of sharp edges at the body of 1 tray;

-exclusion of damage to the insulation and the cable products themselves when they are placed in the tray;

-protection of hands from injuries during the installation of cable routes;

-deformability of the metal of the tray body during bending without the formation of cracks on the metal surface;

- the formation of an internal cavity in the side 3 of the tray body for placement in it of the connecting rod 10;

- springing the connecting rod 10 installed when connecting adjacent trays.

The lower part of this “angular surface passes into another“ angular surface with a rounding of the angular part with a radius of 2 mm. This "angular surface, forming a groove 2 of the housing 1 of the tray, takes in

the response of the lock of the cover 4 of the tray, repeating its geometric shape and thereby ensuring a reliable connection of the housing 1 of the tray with the cover 4.

The lower part of this “angular surface (grooves 2 of the tray body) is mated with the lateral surface of the body 1 of the tray through a recess with a radius of rounding equal to the thickness of the metal of the body 1 of the tray. This recess provides a reliable fixation of the connecting strip 11 or the tray connection 18 mounted inside the housing 1 of the tray, when bonding adjacent trays (figure 5).

On the side walls of the body of the 1 tray there are longitudinal stiffening ribs - 5 bays inside the body of the 1 tray with a rounding radius equal to the thickness other than the material of the tray body.

Due to these sellers 5, the rigidity of the side walls of the housing 1 of the tray and the entire tray as a whole increases.

At the bottom of the body of the tray 1 there are also longitudinal stiffeners - sales 5 inside the body of the tray, located between each of the rows of oval holes 7, oriented along the axis of symmetry of the body of the tray. In addition, along both edges of the bottom of the tray body there are also longitudinal stiffeners - trapezoidal sales 17 to the outside of the tray body 1, which provide additional fixation of the connecting strip 11 or the tray connector 18 mounted inside the tray body 1 when attaching adjacent trays (Fig. 3).

Due to these sellers 5 and 17, the rigidity of the bottom of the housing 1 of the tray and the entire tray as a whole increases.

Perforations were made at the bottom of the body of the tray 1 in the form of round holes 6 arranged along the symmetry axis of the bottom of the body of the tray 6. Corrugated pipes or cables are led out through one of these holes, and studs for attaching the tray to the ceiling pass through the others. Oval holes 7 are made on both sides along the tray body 1 from the round holes 6 and across the tray body between the circular holes 6 at the bottom of the chassis 7. The oval holes 7 located along the tray body are formed by the method

felling, and oval holes 7 located across the body of the tray, formed by the method of cutting with landing along their contour, so that around them there are recesses of the bottom 8 (figure 5), leading to an additional increase in the rigidity of the bottom of the body 1 of the tray.

On the side walls of the housing 1 also made perforation in the form of oval holes 9 (Fig.6), oriented along the body of the tray.

Due to the perforation of the housing 1 of the tray provides:

-Supporting temperature conditions inside the tray;

- Prevention of condensation inside the tray;

-decreasing the weight of the trays, facilitating and simplifying the installation of cable routes.

In the cavity of each side 3 of the housing 1 can be placed connecting rod 10.

The connecting rod 10 is a polished galvanized wire with a diameter matching the diameter of the inner cavity of the side 3 of the locking part of the tray body.

When articulating adjacent trays at sufficiently large angles, a special connecting rod 10 is used, which is a brushed galvanized wire with a stamped 20 along the articulation line of adjacent trays (Fig. 4a).

The cross-sectional shape of the embossing 20 of the special connecting rod 10 repeats the geometric cross-sectional shape of the inner cavity of the rim 3 of the locking part of the tray body 1 (FIG. trays at large angles of articulation.

The connecting rod 10 provides additional rigidity of the corner joints of the trays and an additional guarantee of grounding of the system at the corner joints of the trays. In addition, connecting rods 10

used to strengthen the structure with a large filling of the tray with cable products.

The lid 4 of the tray is a cold-formed profile of pre-galvanized steel with a thickness of 0.55-1.5 mm with a cross section shown in Fig.9.

As can be seen from Fig.9, the edges of the lid 4 of the tray are bent so that the inner cavity of the edge of the lid 14 repeats the outer shape of the rim 3 of the body 1 of the tray, and the outer cavity of the edge of the lid 15 repeats the shape of the groove 2 of the tray, which ensures the tightness of the lid 4 of the tray to the housing 1 of the tray and the reliability of their locking connection.

In the middle of the surface of the lid 4 of the tray there is a longitudinal stiffener - trapezoidal selling 16 to the inside of the lid of the tray. Due to this seller 16 increases the rigidity of the cover 4 of the tray and the entire tray assembly.

The connecting strip 11 is a cold-formed profile of pre-galvanized steel with a thickness of 0.55-1.5 mm, with a cross section shown in Fig.11.

On the lateral surface of the connecting strip 11 there are longitudinal stiffening ribs - bells 12 inside the strip 11 with a fillet radius equal to the thickness of the strip material, which are positioned relative to the bars 5 on the side walls of the tray body 1. Due to these sellers 12, the rigidity of the connecting strip 11 as a whole and the tightness of the fit to the side walls of the housings 1 of the connected adjacent trays of the cable route are increased.

Between the ribs 12 of the connecting strip 11 are perforated, longitudinally oriented oval holes 13 (Fig. 10), positioned relative to the perforated holes on the side walls of the housings 1 of the adjacent trays, due to which bolted connections are provided “tray connecting strip.

In addition to connecting adjacent trays in a line, the connecting strip 11 provides a rigid connection of adjacent trays at an arbitrary joint angle not exceeding 90 degrees, due to the rigid fixation of the strip on the side walls of the adjacent tray housings by means of a bolt connection through the perforations “bar - tray with a preliminary bending of the connecting straps 11 at a given angle along the junction line of the articulated trays of the cable route (Fig. 12).

The trays can have different widths depending on the volume of cable products to be filled at the same height, which allows using the same connecting strips 11 for articulating trays of any width.

The tray connector 18 is a cold-formed profile of pre-galvanized steel with a thickness of 0.55-1.5 mm with a cross section (Fig. 3, 4), repeating the geometry of the cross section of the housing 1 of the tray to the locking part.

The width of the tray connection 18 may be less than the width of the tray body 1 by the amount of two thicknesses of the material of the tray body, then the tray connector is mounted inside the bodies of adjacent trays (FIG. 3).

The width of the tray connector 19 may be greater than the width of the housing 1 of the tray by the amount of two thicknesses of the material of the housing 1 of the tray, then the connector tray is mounted on the outside of the enclosures of adjacent trays (figure 4).

The tray connector provides a rigid connection of the bodies of 1 adjacent trays in a line due to congruent fixation of the latter on the side surface and the bottom surface of the body of the tray 1 using bolt connections through the perforation holes of the tray-tray connector, thereby ensuring their almost complete fit.
