Abstract

A switching cabinet with a rack having a base made of length and depth struts with connected vertical frame pieces. The vertical frame pieces are inserted into a cavity formed by the ends of the length and depth struts and are welded with the base to form a corner connector. It is possible to create a switching cabinet with a simple corner connector mounted on the rack. It is also possible to achieve precise alignment of the vertical frame pieces by providing them with centering pieces which are aligned with stops of the length and depth struts.
