Electronic housing extruded section wall plate e.g. for rack, mounting system - has channels formed to provide location for both circuit boards and insulation plates

摘要

The wall plate used to provide a frame for electronic system housings, e.g. a 19 inch rack mounting system, is in the form of an aluminium extrusion (1) with a cross section shaped to provide rigidity and mounting features. In particular the side sections (6, 7) are produced with channels (8) that receive the edges of a circuit board that can be entered from the side. An improvement in the isolation of the board is provided by lining the inner surface with a plate of insulating material (20). The edge of this locates in a narrow slot (18) in the wall plate. ADVANTAGE - Improved isolation of circuit boards.
