Abstract
A metal frame for an electrical cabinet comprises an assembly of uprights and cross-members forming a framework with high mechanical rigidity. Each upright is provided with a support equipped with four bearing surfaces designed to cooperate with two positioning surfaces of conjugate shapes of a cross-member of the first series to form a fixing device with a hyperstatic wedge when the fixing screw is tightened, which screw passes through a hole of the corresponding cross-member, and cooperating with a lock-nut secured to the support. The nut has a tapped hole arranged in the center of symmetry of the four bearing surfaces of the housing.
