The invention relates to a switching box with a framework support formed from framework side units. The switching box is sealed by having a bottom wall, top wall, two side walls, and the open sides of which can be closed by means of a cabinet door and a rear wall, or by means of two cabinet doors. The framework side units form a hollow profile, which have identical series of holes on the two sides that stand perpendicular to one another and are oriented toward the internal space of the box. The framework side units have a protruding sealing bar on the side which toward the external side of the box. The costs of parts and labor necessary for assembly are reduced while retaining universal construction. At least one portion of the framework side units are formed by multiple bending in a single piece with the bottom wall, the top wall and/or the side walls plates. The edging has a first section which extends perpendicular to the internal side of the plate and at its edge makes a transition into a second section which is bent outwardly and parallel to the plate. The end of the second section makes a transition into a third section which lies on the second section and is extended parallel to the plate beyond the second section. The third section is provided with a series of holes. At the end of the third section, a fourth section is bent perpendicular and toward the internal side of the plate and also have a series of holes.

Switching box

A switch cabinet includes a frame support, the front and rear sides of which are sealable by two casing doors mounted on the frame support, or a casing door mounted on the frame support, and a rear wall attached in a detachable manner on the frame support. HF-shielding of the switch cabinet is achieved when a box-shaped and HF-tight assembly having two side walls, one top wall, and one base wall, is mounted in and connected to the frame support.

Switch cabinet with frame support

A switch cabinet with a mounting board wherein two guide rails extend parallel to the lower side members of the switch cabinet and the mounting board has guide blocks fitted to its lower edge mating with the guide rails. The mounting blocks have a recess in their bottom surface fitting over upwardly extending pegs fitted in the frame unit of the switch cabinet to secure the lower edge of the mounting board. Securement brackets are provided in the upper portion of the frame unit to securely fasten the upper edge of the mounting board when it is in position. The structure of this invention provides simpified installation of the mounting board within the switch cabinet providing positive guidance and securement of the lower edge of the mounting board as soon as it is properly inserted.

Switch cabinet with mounting board

This invention relates to a framework for a switchboard cabinet, comprising at least twelve interlocking frame sections of an identical hollow rectangular structure, in which the hollow rectangular structure has rows of holes and forms an outer corner at the junction of two perpendicular side sections. Opposite the outer corner, the hollow rectangular structure has two side sections, each extending parallel to an opposite side forming the outer corner. The outer corners of all frame sections are aligned correspondingly and face the interior of the framework. Due to the special construction and arrangement of the frame sections, a framework is produced which is expandable with positive sealing on all sides, and in which interconnecting transverse struts, support rails, structural elements and the like, may be installed on all frame sections.
