Frame for under floor communications amplifier - has I=shaped base plate fixed to heat sink and holding subassemblies

摘要

The frame, for underfloor amplifiers in communications systems, has one side closed by a heatsink (6). The electronic sub-assemblies (4) are held by guides (10) and are enclosed by an open-ended metal housing (8) with a base plate (2) made of thermally conducting material and fixed with one side against the heat-sink. The base plate is I-shaped and rests with one crosspiece flat on the heat-sink - which is a metal plate.
