Device for guiding electrical internally built-in items, using metal guide rails

摘要

For the installation of electrical internally built-in items, such as printed-circuit boards, drawers or plug-in assemblies and their common wiring board, guide rails (7) are proposed which consist of an aluminium dye-cast element and, in the case of symmetrical construction, have on the ends centring hooks (37a, 37b) for latching into a grid rail (6) having a division grid and into a common wiring board (8), as well as having on the sides of the guide groove (25) a plurality of spring arms (26 to 29) which produce a good thermal contact between the guide rails and the internally built-in items. In order to improve the thermal contact between the guide rails and a profiled carrier board (10), the guide rails can also be screwed firmly thereto. In consequence, the heat losses produced by the electrical components of the internally built-in items are effectively dissipated. The invention is suitable for the installation of electrical internally built-in items, especially in housings. <IMAGE>
