Definitions

  • This invention relates to the field of modularly constructing electrical cabinet using two- dimensional components. It more particularly relates to the field of low-cost and simple way of construction of high-strength electrical cabinets, offering high- flexibility for internal mounting of components.
  • the invention eliminates the drawbacks of the conventional construction of electrical cabinets and di scloses modular construction of the cabinet from two-dimensional components.
  • Another conventional construction of electrical cabinet is providing welded frames on sides and bolting horizontal members. This type of construction provides proper fitting on the sides but fails to ensure a smooth and air-tight closure and opening of the front door.
  • the door closure problem invariably occurs in the construction of large-width cabinets.
  • another conventional construction of electrical cabinet is providing welded frame each for top and bottom and providing four pillars at the comers. This type of construction too suffers from drawbacks such as instability and proneness of the cabinet to deformation. The problem is inherent in the design of such cabinets, whose long channels are bolted to small top and bottom frames, adversely affecting the squareness of the construction.
  • Another type of the conventional construction for electrical cabinets is providing welded frame for front and rear ends and bolting the side members.
  • This type of construction poses the same problems as are associated with the afore-mentioned constructions, such as instability of the assembled cabinet and imperfect fitment of the sides.
  • US Patent 5,772,296 - This prior work discloses construction of cabinet frame from horizontal and vertical frame legs (10, 20) and depth struts (40), which are angle sections, with open end facing away from the cabinet.
  • the depth struts (40) join horizontal (10) leg frames with the vertical (20) leg frames. It employs a corner element (30) for all four corners and has an inclined surface at 45 degree angle and longitudinal grooves.
  • the present invention is different than the cited work, employing four vertical channels, each providing five or six planes for internal components mounting. No features of the prior work are found in the present invention.
  • US Patent 6,915,616 - This work describes an electrical enclosure, constructed of a complex triangular-cross-sectioned vertical member, which is not used by the present invention. No similarity between the prior work and the present invention is found.
  • US Patent 6,902,068 - This work of art is different in terms of employing a corner piece (20) that opens into 3 -dimensional-axial- wings of a trapezium-top shape. Each wing facilitates joint by press-fitting matching profiled members, horizontally and vertically. The prior does not resemble the present invention in terms of the components used.
  • An object of the present invention is to do away with the use of corner members and complex profiled members for construction and to rely upon using all two-dimensional members for easy transportation to site and easy handling. These costs are significantly reduced with such construction.
  • Another object of the present invention is to allow flexibility to construct electrical enclosure in 1.5 mm, 2.0 mm, 2.5 mm or 3 mm thickness of the members for construction, depending on the nature of application without adding to inventory costs.
  • the present invention entails no special dies, tools for construction of the members in varying thickness.
  • Another object of the present invention is to employ welded front frame, rear frame and side frames to secure their square shape during the assembly and installation at site.
  • Another object of the present invention is to devise an electrical enclosure, freed of instability and deformations and offering enormous flexibility for internally mounting components.
  • the object of the invention is to reduce the cost of construction of the electrical enclosure in transportation, handling, installation, tooling, production and time required for assembly and internal component mounting.
  • the present invention eliminates the drawbacks and limitations associated with the construction and installation of the conventional electrical cabinets as disclosed herein below:
  • An electrical cabinet enclosure (100) is supported on a framework (90), which is constructed by bolting or riveting two-dimensional components such as channels (50), trays and frames.
  • the framework (90) comprises:
  • the four channels (50) are characterized by being constructed of two longitudinal sections (51 , 52), which have trapezium-shaped perimeter of two or three sides perpendicular to one another.
  • the section (51) is characterized by being closed at the lateral ends thereof by a plate (77) and the section (52) is characterized by being closed at the lateral ends thereof by a plate (78).
  • the sections (51 , 52) are characterized by longitudinally being joined by welding 45-degree angular edge of largest side of said section (51) with 45-degree angular edge of largest side of said section (52) to form a bend (72) of the channel (50).
  • the sections (51, 52) are made of single metal sheet folded to form -the shape - as shown - of suitable thickness from 1.5 mm, 2 mm, 2.5 mm to 3 mm.

Abstract

Les coffrets d'armoire électrique reposent sur des pièces d'angle complexes pour leur construction, qui sont pour la plupart préassemblées et transportées jusqu'aux sites d'installation. Le coût de fabrication de profilés complexes et de pièces d'angle complexes et de transport et de manipulation des structures préassemblées sont les inconvénients des travaux antérieurs rapportés. La présente invention, par utilisation de composants bidimensionnels, non seulement élimine les inconvénients des travaux antérieurs, mais encore rend beaucoup plus simple la fabrication, la manipulation et le transport de composants bidimensionnels et requiert beaucoup moins de main d'œuvre. Elle s'appuie sur un profilé en U, entièrement fabriqué d'une seule tôle, à titre d'élément vertical de l'ossature, qui facilite trois raccordements de profilé en U en profondeur et trois en largeur pour un montage interne de composants.
