The invention relates to radio engineering, in particular, to radio-electronic devices containing volumetric installation laid in them.

The purpose of the invention is to improve the technological design.

This goal is achieved by the fact that the additional mounting panel is made with a metallized layer, to which the casing wires of the internal fixture connectors and external mounting connectors are electrically connected.

FIG. I shows the proposed stand, cut, right view; in fig. 2 is a section A-A in FIG. one; in fig. 3 is a section BB in FIG. one; in fig. 4 - an additional panel with mounting performed on it; in fig. 5 is a view of B in FIG. four; in fig. 6 — node I in FIG. 4 (signal and case wires threaded through the holes of the additional panel are shown); in fig. 7 - section G-Y in FIG. five; in fig. 8 is a section DD in FIG. four; in fig. 9 is a view E of FIG. four; in fig. 10 — node II in FIG. 9.

The instrument rack contains the main I and an additional 2 panels housed in the housing 3. On the main panel 1, there are internal device connectors 4. External-mounted connectors 5 are connected to the internal device connectors 4 by means of signal 6 and case 7 wires. In the additional panel 2, holes 8 are made, located in accordance with the contacts of the in-appliance connectors 4, into which the ends of the signal b and case 7 wires are threaded. The additional panel 2 is made with a metallized layer to which the free ends of the casing wires 7 are soldered both from the side of the in-appliance connectors 4 and from the side of the connectors 5 of external installation. The signal wires 6 are laid on the surface of the metallized layer of the additional panel 2 in intersecting directions in accordance with the wiring diagram. Outside the additional panel 2, wires 6 and 7 are twisted in pairs and bundled 9. Wires 6 are fastened to panel 2 by pressing them with wire 10 and soldering it to contacts 11. Harness 9 is fixed on the edge of the panel 2 with yarn ties 12. Main panel 1 is made as separate panels 13 for individually fastening each intra appliance connector 4. Panels 13 are fixed on shelves 14, to the other side of which an additional panel 2 is attached.

The instrument rack is made as follows.

In the process of installation, an additional panel 2 with marked holes 8 is used as its support, imitating in its location the contacts of the intra-instrument connectors 4 installed in

rack. The signal wires 6 are placed on the surface of the panel 2 in accordance with the circuit diagram of the device along straight lines between the corresponding holes 8 of the panel, and

also between the holes 8 and the sections of the panel 2 for bandaging the wires connected to the output connectors 5. For connection with the in-appliance connectors 4 through the openings 8 of the panel 2, imitating the arrangement of the contacts of these connectors, pass the signal wires 6 and 7 The panels 2 with the case contacts of the in-appliance connectors 4, solder one of the ends of the wires 7, threaded through the holes 8, to the contacts 11 of the panel 2. On the surface of the last wire they are fastened by pressing them with wire 10 and soldering it to the contacts 11 of panel 2. In the section from the edge of the latter to the output connectors 5 in order to provide noise immunity of the signal circuits

0 twist the signal wires 6, laid on the panel 2, with the wires 7 in pairs.

The ends of the signal wires are fed to the corresponding contacts of the output connectors 5, and the wires 7 twisted in pairs with

 signal wires 6, are soldered at one end to the case contacts of the connectors, the other end to the contacts 11 of panel 2. Pull the wires into the harnesses 9 from the edge of the panel 2 to the output connectors. The flap is attached to the edge of the screen with thread straps 12. Turn panel 2 over, solder the wires to the contacts of the in-appliance connectors, monitor the installation and eliminate the malfunctions. Then, the panel 2 with surround installation is installed in the housing 3, while the panels 13 with the internal appliance connectors mounted on them are inserted from the rear part of the housing through an opening formed by the shelves 14 of the housing construction. Output connectors are inserted into the upper compartment of the housing and

0 is attached to its front (front) panel, panel 2 is attached to the case, ensuring its isolation from it
