The invention relates to the field of radio engineering and can be used in the design of non-structural structures of electronic equipment.

The purpose of the invention is to improve the convenience of operation by reducing the time of assembly and disassembly of the body of the unit and providing greater access to the electrical radio elements installed in it.

Fig. 1 shows the housing of the radio-electronic unit, a view, axonometric; FIG. 2 is the same side view; FIG. 3 is a section A-A in FIG. 2; FIG. 4 is a section BB in FIG. 2; Fig. 5 shows the housing of the electronic unit when the front panel is removed, front view; Fig, 6 is a section bb In Fig, 5; Fig, 7 - front panel cross section.

The body of the electronic unit contains a front panel 1, a rear panel 2, a chassis 3, side walls 4 and 5 hinged to the chassis; node 6; fixing panels 1 and 2 and walls 4 and 5, consisting of L-shaped flanges 7, made in side walls 4 and 5, of L-shaped flanging 8, made in the front and rear panels x 1 and 2, of the fixation element in the form of a 9-C-section bar, and shelves 10, rigidly connected with panels 1 and 2 (two for each each panel). On side walls 4 and 5, nodes 11 are installed to restrict the rotation of the walls, each of which consists of strips of rotational stops in the form of forks 12 and 13 rigidly fixed to the side walls 4 and 5, and a strap 14 placed between the forks 12 and 13 and provided with a groove 15, and an axis 16 connecting the forks with the tie bar and moving along the groove 15 of the yoke 14. The panels and 2 are provided with plugs 17 serving to fix the forks 12 and 13 of the knots 1 1 to the non-running position. The hinged connection of the side walls 4 and 5 with the right side 3 is realized by means of the lugs 18 and the axis 19,

Dp to ensure the normal thermal mode of the chassis unit 3 is provided with perforations 20, the front panel 1 is provided with a niche 21 for accommodating terminal kits. To ensure that the panels i and 2 fit snugly against the walls 4 and 5, seals 22 are mounted on the panels. The slats 9 are provided with notches 23 intended for

In order to remove the slats when disassembling the block, grooves 24 are provided in walls 4 and 5 to accommodate shelves 10 of panels I and 2 and slopes 25 limiting the rotation angle of the walls to 45. The block is fixed in racks and control cabinets through holes 26 or niches 27, Forks 12 are provided with holes 28, and plugs 29 with through-holes are mounted on forks 13. The panel 2 bends 30. The flanging 7 of the wall 4 (or 3) assembled with the flange 5 of the panel 8 of the panel I (or 2) forms a T-shaped protrusion 31. On the side walls 4 and 5, cooling fins 32 can be made,
