Mettalic structure improvement for manufacturing electrical cabinets

Abstract

Improvement to the metallic structure for manufacturing electrical panels / cabinets, enclosing a structure of metallic cross sections (5), with the means for supporting the parts making up the external walls from folded sheets, as well as constituting the means for supporting and mounting the doors with its respective hinges, the upper (6) and lower enclosure with the base (7) and other electrical and electronic inside of the cabinet components.The said structure (5) can be presented semi-assembled, where four of its uprights or four of its cross sections (P1) are completely free whilst all the other cross sections are rigidly integrated into two equal rectangular frames (8) which form the two opposite sides of the said structure (5) and therefore at the corner point of the junction of each rectangular frame (8) there is a complementary device (9) cooperating for the interlinking at 90 DEG between two adjacent cross sections (P2) and (P3) of each frame (8), as also this selfsame device presents the means so that the extremities of the other cross sections (P1) may be coupled between the corners of the rectangular frames (8), thus forming the structure (5).

Description

technical field [0001] The present invention relates to metal structures assembled with combinations of different parts comprising special intersection sections, in particular of the type formed in an extrusion press, which define a structure with a constructively different concept from which it is possible to obtain Some technical and application improvements, including quality assurance and cost reduction. [0002] In the usual way, such structures are commonly used in a variety of cabinet types, also known as switchboards, which are actually cabinets with doors and closed sides, used to house many kinds of electrical and electronic components and device. Background technique [0003] According to the general knowledge of those skilled in the art, there are different types of power distribution boards, also known as frames or cabinets, which are designed to accommodate a wide variety of components in many industries, including telephones department. [0004] The use of ...

AI Technical Summary

Problems solved by technology

However, this assembly concept can characterize different technical and application drawbacks, among which we can highlight: increased manufacturing costs; its transportation and storage become more difficult, because the assembled structure needs to occupy a considerable amount of space

[0021] In the second common state, it can be said that there are other types of detachable structures, that is, structurally assembled using screws, each of which represents its individual structural features, however, these existing solutions are not suitable for the intended application Does not provide satisfactory stiffness or mechanical stability
