A frame for a switchgear cabinet is made up of frame members and corner joints. The corner joints are provided with plug-in rods in sockets and are joined to the frame members. The frame members are designed as open hollow sections that are bent several times, are symmetrical to their diagonal and open in the area of their inner sides. The section sides of the frame member continuing beyong its outer perpendicular section sides are bent inwards several times to form sockets for the plug-in rods of a corner joint. The resulting sockets provide at least two points of contact with the insert plug- in rods spanning more than 180·. This yields a frame with hollow sections that are easy to manufacture, with low expenditures for parts and assembly.

Une baie pour armoire de distribution est constitué de montants et de cornières. Les cornières sont pourvues de broches enfichables dans des cavités et sont reliées aux montants. Les montants sont constitués de sections de profilés creux ouverts pliées plusieurs fois, symétriques par rapport à leur diagonale et ouvertes au niveau de leurs faces intérieures. Les sections des montants qui prolongent les côtés des profilés formant les côtés extérieurs perpendiculaires sont repliés plusieurs fois vers l'intérieur pour former des cavités destinées aux broches d'une cornière. Les cavités ainsi obtenues s'appuient en au moins deux points séparés de plus de 180~ sur les broches insérées dans les cavités. On obtient ainsi avec un faible investissement en pièces et en montage une baie constituée de sections profilés creux faciles à produire.
