FR2502447A1 - Electronic equipment case for printed circuit board - has symmetrical top and bottom and front and rear panels and has slots for horizontally or vertically mounted cards - Google Patents

Abstract

The equipment case has identical side walls (3,4) and top and bottom faces (1b,2b). The top and bottom faces are U-shaped with right angled side sections which fit together (2a,1a) to form the whole side panel. The four panels screw together (5,6) to enclose a rectangular volume. Front and rear panels have a pair of vertical brackets (4a,4b,3a,3b), each with a series of regular slots. The internally folded rims (4c,4d) also have slots cut in them. Circuit cards can be held horizontally, with their corners fitting in the slots in the vertical brackets, or vertically, with edges held in the vertical slots (4c,4d) in the front and rear panels. Intermediate brackets carrying horizontal slots can be fitted to allow the space to be sub-divided for horizontally or vertically mounted cards. The angle between the borders (3c,3d,4c,4d) and their respective panels (3,4) is slightly less than 90 degrees which permits the pivoting of the front faces (3,4) when work is carried out on the cards. This arrangement also ensures that the cards are firmly held by their respective slots (3c,3d,4c and 4d).

Description

 The subject of the invention is a bolier intended for electronic or electrical assemblies.

 The object of the invention relates to the technical sector of receptacles, in particular for the installation of cards intended to receive various assemblies of electrical, electronic components, etc.

 Known boxes or shoemakers intended to perform electronic or electrical assemblies, are generally made of molded plastic or metal, and they are in the form of a bowl with a cover, or of a tunnel-type envelope whose openings receive shutter elements. Interior positioning elements must be brought back.

These configurations make it difficult and difficult to manipulate and mount cards and other elements, connections and soldering.

The costs of these boxes and shoemakers are relatively high when it is necessary to assemble various parts.

 The bootmaker according to the invention by its ra tiorttelles and advantageous design and construction, overcomes these drawbacks.

 This boot maker is mainly characterized in that it consists of four elements (1, 2, 3) and (4) assembled which are of two different types, identical two by two and assembled symmetrically; the two elements of the first type (1) and (2) having a general U-shape, the branches or sides (la) and (2a) of which appear opposite, delimiting the volume of the shoemaker, between said branches (la) and (2a) and so as to close the volume, being fixed the two elements of the second type (a) and (4) which are faces arranged to allow the convenient and rapid positioning of the cards carrying the circuits, components or the like, and for allow the assembly of various electrical or electronic construction elements.

 These characteristics and others will emerge from the following description.

In order to make the object of the invention more concrete, I now describe and in a nonlimiting manner with reference to the examples of the figures of the drawings;
We see Figure 1, that the boot according to the invention consists of four elements (1) - (2) - (3) and (4) of two different types being identical two by two and assembled symmetrically.

 The two elements (1) and (2) of the first type have a general U-shape whose branches or catés (la) - (2a) appear opposite, delimiting the volume of the bootmaker. Between the said branches (la) and (2a) are fixed the two elements (3) and (4) of the second type so as to close the volume.

 The elements (3) and (4} are faces arranged to allow convenient and rapid positioning of the cards (C) carrying the circuits, components or the like (FIG. 2). To this end, the faces or panels (3) and ( 4) constituting the elements of the second type, present on at least two opposite sides and preferably on the four sides, edges folded inwardly (3a), (3b), (3c), (3d) and (4a), 44b) , (4c)> (4d) with each of the open slots (3a1), (3bl), (3c1), (3dl) and (4al), (4bl), (4c1) and (4dt), for positioning the cards (VS).

 At least two opposite folded edges, in particular the vertical edges (3a - 3b) and (4a - 4b), have at each upper and lower end, internally squared legs (3a2 - 3b2) and (4a2 - 4b2) each provided with lights oblong (O) or other arrangements, for assembling and fixing electrical or electronic construction elements.

 The faces (3) and (4) for positioning and mounting the cards (C) are first fixed between the branches or sides (la) of one of the U-shaped elements (1), for example by means of a screw ( 5), so that one has convenient access to the interior space of the shoemaker, and that one can also pivot one or both sides (3) and (4) as required, to facilitate the assemblies and handling, said faces (3) (4) then being fixed between each of the branches (2a) of the other U-shaped element, by a screw (fi) symmetrical to the first (Figure 3).

 The edges (3c) and (3d) - (4c) and (4d) of the faces (3) and (4), which extend along the bottoms (lob) and (2b) of the U-shaped elements (1) and (2), are folded forming with the said faces, an angle (<at,)) very slightly less than 90 degrees to allow the pivoting of the faces (3) and (4) during assembly work and also to ensure maintaining and holding the cards (C) engaged in the open slots (3cl) (adi) - (4cl) and (4d1) formed on these edges (3c and 3d) - (4c) and (4d) Figure 4.

 The edges (3a) and (3b) - (4a) and (4b) which extend parallel to the branches (la) and (2a) of the U-shaped elements (i) and (2), have a folded in (3a3) and (3b3) - (4a3) and (4b3) of their parts carrying the open slits (3a1) and (3bl) - (4al) and (4b1), so as to provide an interval (e) between said slit parts and the branches (la) and (2a) of the U-shaped elements (i) and (2), the interval (e) ensuring the maintenance and the holding of the cards (C) engaged horizontally in the slots (3a1) and (3b1 ) - (4al) and (4b1) figure 5.

 The faces (3) and (4) are fixed between the branches (la) and (2a) of the LI elements (1) and (2) with a position set back relative to the ends of the said elements (1) and (2 ) so as to ensure the protection of the various control and / or control means which may appear projecting from the said faces (3) and (4) which are in this case arranged for this purpose.

 The longitudinal edges (3c and 3d) - (4c and 4d) of the faces (3) and (4) allow the vertical positioning of the cards (C), while the vertical edges (3a and 3b) - (4a and 4b) allow the horizontal positioning of the cards (C) in figure 2.

 There is also the possibility of putting cards in the boot according to the invention, which are placed in combination in a vertical and horizontal manner. For example, as shown in FIG. 7, the faces (3) and (4) shaped as indicated above, internally each have an attached intermediate vertical element (7) forming a folded square edge (7a) with open slots ( 7al) to allow, over part of the length of the faces (3) and (4) and in combination with one of the vertical folded edges (3a) or (ab) and (4a) or (4b), the horizontal positioning one or more cards (C), while on the remaining length, are positioned vertically in combination with the horizontal edges (3c) - (3d) and (4c) (4d), one or more cards (C2). Draw in broken lines in Figure 7.

 Cut plates (8) and (9) forming grips and handling handles, are attached and fixed against the U-shaped branches of the elements of the first type (1) and (2) using in particular the assembly screws and fixing (5) and (6) of the faces (3) and (4).

 The bottoms (lob) and (2b) of the U-shaped elements of the first type (1) and (2) have slots, multiple perforations (lb i) and (2bl), or other ventilation openings from the inside. of the bootmaker. The elements (1) and (2) and (3) and (4) constituting the shoemaker and the handles (8) and (9) are made of metal sheet, preferably of zinc-plated aluminum alloy, and are produced by cutting. , punching, folding.

 It is obvious that according to the invention, the bolier can be made in all dimensions. Self-adhesive feet, made of flexible material, can be fitted to one of the U-shaped elements (1) and (2).

 The advantages are clear from the description, in particular it is emphasized: - the ease of access to the interior of the case for the placement of the cards with the possibility of pivoting one or both sides to facilitate handling - the simplicity of implementation - the ease and speed of assembly - the many possibilities for mounting electrical panels.

 The invention is in no way limited to that of its modes of application, nor to those of the embodiments of its various parts which have been more particularly indicated; on the contrary, it embraces all its variants.
