Assembly device for framework sections, corresponding framework, and cabinet, particularly cabinet for electrical equipment, implementing such a framework

摘要

This is, in particular, an assembly device (34) which, for the assembly of two framework sections (12), the flanges (13) of which are each equipped with a folded-over part (16) with, between the latter, a closure wall (18) defining, together with them, a tubular passage (20), implements an assembly piece (35) including two branches (36) each capable of receiving such a framework section (12) by simple interlocking. According to the invention, on at least a part of their length, the branches (36) of this assembly piece (35) have, in transverse section, a contour which at least partly complements that of the space that the closure wall (18) and the turned-back portions (16) of the flanges (13) of the framework sections (12) define between them, outside the tubular passage (20) of these sections. Application, particularly, to cabinets for electrical equipment. IMAGE
