Abstract
Description
La présente invention concerne un coffret métallique pour appareillages électriques, comprenant plusieurs parois latérales, une paroi arrière et une paroi avant telle qu'une porte ou un couvercle, les parois latérales étant constituées par un seul flan de tôle plié en ceinture. The present invention relates to a metal cabinet for electrical equipment, comprising a plurality of side walls, a rear wall and a front wall such as a door or a cover, the side walls being constituted by a single sheet of flange folded belt.
De tels coffrets sont bien connus et, parmi les qualités que l'on attend d'eux, on compte la rigidité de construction et la protection contre le risque d'introduction d'eau. Such cabinets are well known and among the qualities expected of them include the construction rigidity and protection against the risk of water introduction.
L'invention a pour but d'améliorer au moindre coût la rigidité d'un tel coffret, en même temps que de renforcer la protection contre le risque d'introduction d'eau à l'intérieur du coffret. The invention aims to improve the rigidity of such a cabinet at the least cost, at the same time as reinforcing the protection against the risk of introducing water into the cabinet.
Selon l'invention, la ceinture comprend une surface principale bordée par un ban deau avant et un bandeau arrière, les bandeaux étant pliés au moins perpendiculai rement à la surface principale, et rehaussés par rapport à la surface principale d'une hauteur permettant l'évacuation d'eau. Les bandeaux peuvent être raccordés à la surface principale par un pli de transition par exemple à 45 . According to the invention, the belt comprises a main surface bordered by a front band and a rear band, the bands being folded at least perpendicularly to the main surface, and raised relative to the main surface by a height allowing water evacuation. The strips can be connected to the main surface by a transition fold for example 45.
Une gouttière peut être formée sur le bord du bandeau avant pour contribuer, avec l'espace formé au-dessus de la surface principale, à améliorer l'évacuation de l'eau. L'une des parois latérales peut comprendre dans la surface principale des zones défonçables préformées par prédécoupage avec un contour continu, c'est-à-dire sans perforation locale de la tôle, avec un retrait qui peut correspondre aux deux tiers environ de l'épaisseur de la tôle. A gutter may be formed on the edge of the front band to contribute, with the space formed above the main surface, to improve the evacuation of water. One of the side walls may comprise in the main surface knockout areas preformed by pre-cutting with a continuous contour, that is to say without local perforation of the sheet, with a withdrawal which may correspond to about two thirds of the thickness of the sheet.
La description va être faite ci-après d'un mode de réalisation non limitatif de l'inven tion, en regard des dessins annexés. The description will be made hereinafter of a non-limiting embodiment of the invention, with reference to the accompanying drawings.
La figure 1 représente en perspective un coffret métallique conforme à l'invention. La figure 2 est la coupe de la partie supérieure du coffret. La figure 3 est une vue agrandie de la figure 2. Figure 1 shows in perspective a metal cabinet according to the invention. Figure 2 is the section of the upper part of the cabinet. Figure 3 is an enlarged view of Figure 2.
La figure 4 montre à plus grande échelle une zone défonçable ménagée dans la surface principale. Figure 4 shows on a larger scale a knockout zone formed in the main surface.
Le coffret représenté 10 est destiné à loger des appareils et conducteurs électri ques.<B>Il</B> est métallique et comprend sur quatre côtés des parois respectivement su périeure 11, latérales 12,13, et inférieure 14 ; il comporte de plus une paroi arrière 15 et une ouverture avant 16 destinée à être fermée par une paroi avant telle qu'une porte ou un couvercle 17. Les parois latérales 11-14 sont constituées par découpe et pliage d'un seul flan de tôle métallique plié de manière à être refermé à la manière d'une ceinture, en étant soudé à un angle selon une ligne telle que 18. La ceinture comprend sur les quatre parois 11-14 une surface principale 20, ainsi qu'un bandeau avant 21 et un bandeau arrière 22, les bandeaux 21,22 ayant une partie parallèle à la surface 20, puis une partie pliée pour être rabattue, avec ou sans écrasement à 180 , perpendiculairement à la surface principale. La partie pliée du bandeau avant 21 est convenablement découpée aux angles de la ceinture pour y permettre un assemblage soudé des éléments de partie pliée correspondant aux parois successives. The box 10 shown is intended to house apparatus and electrical conductors. <B> It </ B> is metallic and comprises on four sides respectively upper 11, lateral 12,13, and lower 14; it further comprises a rear wall 15 and a front opening 16 intended to be closed by a front wall such as a door or cover 17. The side walls 11-14 consist of cutting and folding a single sheet blank metal belt folded to be closed in the manner of a belt, being welded at an angle along a line such as 18. The belt comprises on the four walls 11-14 a main surface 20 and a front band 21 and a rear strip 22, the strips 21,22 having a portion parallel to the surface 20, then a folded portion to be folded, with or without crushing 180, perpendicular to the main surface. The folded portion of the front band 21 is suitably cut at the corners of the belt to allow a welded connection of the folded part elements corresponding to the successive walls.
Les bandeaux 21,22 sont rehaussés d'une hauteur h1 de l'ordre de 2 à 3 mm, c'est- à-dire égale à au moins environ deux fois l'épaisseur e de la tôle, ici égale à 1 mm, par rapport à la surface principale 20, de manière à conférer une bonne rigidité à l'enveloppe du coffret et à créer au-dessus de cette surface un espace A propre à l'évacuation d'eau. Les bandeaux 21,22 sont raccordés à la surface principale par un pli de transition oblique 23, par exemple incliné à 45 par rapport à la surface principale. The strips 21,22 are raised with a height h1 of the order of 2 to 3 mm, that is to say equal to at least about twice the thickness e of the sheet, here equal to 1 mm, relative to the main surface 20, so as to provide good rigidity to the casing of the cabinet and to create above this surface a space A suitable for the discharge of water. The strips 21,22 are connected to the main surface by an oblique transition fold 23, for example inclined at 45 relative to the main surface.
II convient d'observer que le bandeau avant 21 est formé par une face 21a parallèle à celle de la surface principale, à laquelle succède une face 21 b pliée perpendicu lairement à 21 a, puis une autre face 21c parallèle à 21 a et s'étendant vers l'avant, puis un rebord 21d incliné vers l'extérieur de l'ouverture 16 et destiné à coopérer avec un joint d'étanchéité 19 (voir figure 2) situé sur la porte 17. Une gouttière B est ainsi définie par les faces 21 b,21 c et le rebord 21 d le long de la paroi supérieure 11 et, en combinaison avec l'effet d'évacuation d'eau dû à l'espace A surmontant la surface principale et confiné entre les bandeaux 21,22, contribue à donner d'excel lentes propriétés d'étanchéité au coffret décrit Le bandeau arrière 22 comprend une face 22a parallèle à la surface principale, une face 22b repliée à 180 sur 22a et une face 22c pliée perpendiculairement à 22a et 22b. La paroi arrière 15 est soudée sur la face 22c. It should be noted that the front band 21 is formed by a face 21a parallel to that of the main surface, followed by a face 21 b folded perpendicularly to 21a, then another face 21c parallel to 21a and s' extending forward, then a flange 21d inclined outwardly of the opening 16 and intended to cooperate with a seal 19 (see Figure 2) located on the door 17. A gutter B is thus defined by the faces 21b, 21c and the flange 21d along the upper wall 11 and, in combination with the effect of water evacuation due to the space A overlying the main surface and confined between the strips 21,22 The rear band 22 comprises a face 22a parallel to the main surface, a face 22b folded at 180 on 22a and a face 22c folded perpendicular to 22a and 22b. The rear wall 15 is welded to the face 22c.
Des zones défonçables 24 sont prévues dans l'une des parois 11-14 pour permettre de faire passer des câbles (voir figure 4). Les zones défonçables 24 ont par exem ple un contour circulaire et sont préformées par prédécoupage dans la surface prin cipale de la paroi 11 ou 14. Les zones 24 sont prédécoupées avec un contour net dans la tôle de la paroi latérale, avec par rapport au reste de la surface 20 un retrait h2 correspondant à environ 2I3 de l'épaisseur e de la tôle, sans qu'il soit besoin de prévoir des perforations locales sur leur contour ; ceci assure l'étanchéité et auto rise un défonçage précis quand on souhaite ôter l'une ou l'autre de ces zones pour créer le passage souhaité.Knockout areas 24 are provided in one of the walls 11-14 to allow cables to pass (see Figure 4). The knock-out zones 24 have, for example, a circular contour and are preformed by precutting in the main surface of the wall 11 or 14. The zones 24 are pre-cut with a sharp contour in the sheet of the lateral wall, with respect to the rest of the surface 20 a shrinkage h2 corresponding to about 2I3 of the thickness e of the sheet, without the need to provide local perforations on their contour; this ensures watertightness and enables precise routing when removing one or other of these zones to create the desired passage.
