RADIO-ELECTRONIC UNIT Russian patent published in 2011 - IPC H05K1/00 H05K7/02 H05K7/14 H05K7/18 

FIELD: electricity.

SUBSTANCE: radio electronic unit, comprising a body made of front, rear, first and second side panels, upper and lower covers, a circuit board that carries electronic nodes and arranged in the inner space of the radio electronic unit, besides, the rear panel, upper and lower covers are arranged as the first integral "П"-shaped structure, additionally the front, first and second side panels are made in the form of the second integral "П"-shaped structure, in the first side panel in part that adjoins the front panel, in the front panel in part that adjoins the second side panel, and in the rear panel there are windows, at end and side surfaces of the upper and lower covers and at the ends of the first and second side panels there are ledges, ledges at the side surfaces of the upper and lower covers are made at the side of the first side panel, and ledges at end surfaces of the upper and lower covers are made at the side of the second side panel, besides, ledges at the ends of the first and second side panels may enter into windows on the rear panel, ledges at the side surfaces of the upper and lower covers may enter into windows on the first side panel, ledges at end surfaces of the upper and lower covers may enter into the windows of the front panel, and fixation of the first and second integral structures is done with the help of a fixator arranged on the front panel at the side of the second side panel. The fixator is a screw with a nut, besides, the screw is pulled through a hole in the front panel, and the nut is fixed at the lower cover. The fixator is arranged in the form of a spring-loaded stop and a guide, besides, the fixator is arranged at the inner side of the front panel, the stop is installed in the guide, partially protrudes beyond the guide, may move in the guide and partially enter into the lower cover window. The first side panel along height is not less than the distance between the external surfaces of the upper and lower covers, and the second side panel along height is not more than the distance between the inner surface of the upper and lower covers, besides, the second side panel may enter between the inner surfaces of the upper and lower covers. Windows in the front, rear and first side panels are arranged as throughput.

EFFECT: simplified assembly and disassembly of radio electronic unit, also in replacement of electronic circuit boards and nodes inside the unit, to eliminate chances of erroneous assembly.
