A transformer having an integral cabinet with an apparatus for hinging and clamping the cover of the cabinet onto its base is provided. The hinge is formed by an L-shaped member extending from a lip surrounding a planar top formed in the cover. A flange having rearward and downward extending portions extends from the rear wall of the cabinet base. The hinge engages a slot formed in the downward extending portion of the flange. The distance from the hinge to the cover top is less than the distance from the slot to the upper edge of the rear wall on which the cover top rests. Thus, rotation of the cover into the closed position with the hinge engaged causes elastic deformation of the hinge, thereby creating a spring force which clamps the cover onto the base. Elastic deformation in the flange imparts addition clamping force. Sufficient clearance is provided for this elastic deformation by either sloping the rearward extending portion of the flange or sloping the planar top of the cover.
