Abstract: The claimed corner-profile strip comprises a strip-shaped support section for a lateral housing panel, a strip-shaped spacer section approximately perpendicular to the support section, and a strip-shaped contact section oriented approximately parallel to the support section and inwards away from the spacing section. An advantage here is the single-piece design of the corner strip which combines the functional qualities of a mechanical connecting component for essential housing parts with those of a contact component used for electromagnetically shielding the mounting rack. The all-purpose capability for securing contact spring strips and as a contact counter surface for spring elements reduces the complexity of manufacture and assembly. This means that a corner strip of a single type can be used at each of the four corners of a mounting rack.
