Description

The invention relates to radio engineering and can be used in the design of supporting structures of electronic equipment.

The purpose of the invention is to increase the rigidity of the structure by introducing additional elements of the corresponding form into it.

Figure 1 shows the electronic unit, in a perspective view; FIG. 2 is a view A of FIG. 1; on fig.Z - section bb in figure 2; on .fig.4 - electronic unit, view in axonometry, disassembled.

Radioelectronic, the unit contains a body formed by a base 1, panels 2 and 3 with fastening elements in the form of leaf springs 4 cantilever-mounted on them 4. a cover 5 and side surfaces 6 frames 7 of subblocks 8, ycraJ

in the case and made in the form of 10 connectors fixed on frames 7 with forks, 10 U-shaped brackets 11 with holes 12 for projections 13 on other side surfaces of frames 7 of subunits 8, with openings 14 for forks 10 boards 9 of the same subunits and with folds 15 for securing the cross-boards 16, on which plugs 17 and sockets 18 of connectors are mounted. In this case, in panels 2 and 3, openings 19 are made for external sockets 20 sockets (Fig. 1). Guides 21 are provided in the base 1 and in the lid 5 to accommodate the panels 2 and 3 and install the strips 22 with screws 23 to fasten the outermost sub-blocks 8 (Fig. 2). and in the lateral surfaces of the frames 7, which are perpendicular to their lateral surfaces 6, grooves 24 are made under the plugs 10 of the connectors of the boards 9.

When assembling the electronic unit, the boards 9 are attached to the frames 7, placing the plugs 10 of the connectors of the latter in the slots 24 of the frames 7. The resulting subunits 8 are installed in the required height sequence. The corresponding brackets 11 are fixed on the frames 7 of the respective subunits 8 by placing in the holes 12 projections 13 of the frames 7, and in their openings 14 - forks 10 boards 9 of the same subunits. Fasten the corresponding cross-boards 16 on the bends of the 15 corresponding brackets 11, connect the sockets 18 of their connectors with the plugs 10 of the boards 9 of the corresponding sub-blocks 8. Attach the base 1 and the cover 5 to the extreme sub-blocks using the strips 22 and screws 23. 21 bases and covers of panel 2 and 3 fixing them with springs 4, after which, if the electronic unit is to be operated, combine the sockets 20 of external mounting connectors with the corresponding plug 17 of the corresponding cross-board 16.

The dismounting of the electronic unit is carried out in the reverse order.

Supply of the subunits of the electronic unit with the framework, as well as the implementation of the elements of the mechanical connection of the subunits among themselves and with the cross-boards in

The shape of the U-shaped brackets allows you to increase the rigidity of its design.

Claims (1)

The invention includes a radio-electronic unit comprising a case formed by a base, side walls and a lid, subunits in the form of boards with plugs of plugs, cross-boards with sockets and plugs of plugs on the opposite sides, installed in the hull and electrically connected to the boards, elements of the mechanical connection of the sub-blocks among themselves and with cross-boards and fasteners, characterized in that, in order to increase the rigidity of the structure, each sub-block is provided with a frame with protrusions on one them from its side surfaces, each element of the mechanical connection of the subunits among themselves and with the cross-boards is made in the form of a U-shaped bracket with holes and openings installed with the possibility of fixing on it the corresponding cross-board and placing protrusions on one of its holes from the side surfaces of the frames, the corresponding sub-blocks, and in its openings the plug forks of the same sub-blocks installed with the possibility of the formation of other side surfaces of the frames and the corresponding side walls of the housing. eight 0U8.i 6-5 l 2 jg / 17ii Figm // j
