Abstract

A corner connector for a switching cabinet with depth and length struts which are disposed horizontally and joined to vertical frame pieces in corner areas by corner connectors. Substantial flexibility of use is achieved with the corner connector having a compensating element enabling differently structured vertical frame pieces to be connected according to choice.

Claims2

Dependent claims

In a rack for a switching cabinet with horizontal depth struts and length struts to which vertical frame legs are attached in corner areas via corner connections where each of the corner connections has a compensating piece, the improvement comprising:

the compensating piece (40) accommodating differently structured ones of the attached vertical frame legs (10, 70) and the compensating pieces (40) each secured within an open spacing between adjacent ones of the vertical frame legs (10, 70);
the depth struts and the length struts (20, 30) formed as hollow profiles having openings accommodating one of a plurality of vertically standing inserts (50, 60) in the corner areas of the rack, the compensating pieces (40) introduced into the open spacings;
the spacing between the vertical frame legs (10) set to one of metric and English component dimensions;
the length struts and the depth struts (20, 30) having a same cross-sectional form and bent from one section of sheet metal, the length struts and the depth struts (20, 30) having a horizontal cover section (21, 31) to which an angled section (22, 32) running parallel to an outer side of the rack adjoins and to which a perpendicular fold (23, 33) adjoins, a wall (24, 34) extending parallel to the angled section (22, 32) adjoining the perpendicular fold (23, 33) and with the perpendicular fold (23, 33) forming an opening recessed with respect to the angled section (22, 32) and the wall (24) extending into a base part (26, 36);
the cover section (21, 31) set back in a longitudinal direction of the depth struts and the length struts (20, 30) with respect to the base part (26, 36) forming an opening for one of the inserts (50, 60);
and
one of the vertically standing inserts (50) introduced into the opening formed in the corner area, abutting the wall (24) of the depth strut (20) with a fastening section (52), and abutting a stop face (41) of one of the compensating pieces (40) which is introduced between the one of the vertically standing inserts (50) and the cover section (31) of the length strut (30).
