Description

La présente invention a pour objet une rampe d'alimentation électrique pour dispositifs consommateurs de courant, tels que des systèmes d'éclairage.The present invention relates to an electrical supply ramp for current consuming devices, such as lighting systems.

On connaît déjà des rampes d'alimentation élec­trique présentant une succession de paires de contacts électriques destinées à recevoir chacune un élément con­sommateur de courant, ces rampes comportant des bandes conductrices métalliques avec des saillies formant les contacts électriques qui traversent des fentes pratiquées dans un support isolant.Electric supply ramps are already known having a succession of pairs of electrical contacts intended to each receive a current-consuming element, these ramps comprising metallic conductive strips with projections forming the electrical contacts which pass through slots made in an insulating support. .

Dans le brevet suisse 599.501 est décrite une rampe d'éclairage dont le support présente des ailes formant entre elles un angle de 90°, des bandes métal­liques étant montées sur les surfaces internes des ailes. Ces bandes métalliques, comportent des clips en L fixés par paires alternativement et à des distances prédéter­minées sur l'une et l'autre des bandes métalliques pour retenir les lampes montées selon l'axe du profil.In Swiss patent 599,501, a lighting ramp is described, the support of which has wings forming an angle of 90 ° between them, metal strips being mounted on the internal surfaces of the wings. These metal bands have fixed L-shaped clips in pairs alternately and at predetermined distances on both of the metal strips to retain the lamps mounted along the axis of the profile.

Par le brevet suisse 652.537, on connaît la possibilité de remplacer les clips en L par des languet­tes découpées dans le sens de la bande et repliées de 90°, l'extrémité de la languette présentant un trou destiné à positionner un contact électrique d'un élément consommateur de courant. Les bandes métalliques sont fixées sur les ailes au moyen de rivets.By Swiss patent 652,537, we know the possibility of replacing the L-shaped clips by tabs cut in the direction of the strip and folded back by 90 °, the end of the tab having a hole intended to position an electrical contact of a current consuming element. The metal bands are fixed on the wings by means of rivets.

La présente invention vise à simplifier le montage des constituants des rampes d'éclairage connues et a pour objet une rampe d'éclairage présentant une succession de paires de contacts électriques comportant au moins deux bandes conductrices ayant à des distances prédéterminées des plaquettes disposées à 90°, dont l'ex­trémité libre est agencée de manière à positionner au moins indirectement un contact électrique d'un élément consommateur de courant.The present invention aims to simplify the mounting of the components of the known light bars and relates to a light bar having a succession of pairs of electrical contacts comprising at least two conductive strips having at predetermined distances plates arranged at 90 ° , the free end of which is arranged so as to position at least indirectly an electrical contact of a current-consuming element.

Elle est caractérisée en ce que les bandes conductrices sont superposées et sont chacune recouvertes par un corps isolant et en ce que les bandes conductrices et les corps isolants présentent des ouvertures pour le passage des plaquettes de la ou des bandes disposées au-dessous.It is characterized in that the conductive strips are superimposed and are each covered by an insulating body and in that the conductive strips and the insulating bodies have openings for the passage of the pads of the strip or strips arranged below.

Dans une première forme d'exécution, un corps isolant intermédiaire sous forme d'une bande plate est disposé entre deux bandes superposées, tandis que le corps isolant supérieur est constitué par un support qui comporte un dégagement longitudinal limité par des ailes de protection et destiné à recevoir les bandes conduc­trices et le (ou les) corps isolant intermédiaire. Ce support comporte en outre des fentes transversales pour le passage des plaquettes de contact.In a first embodiment, an intermediate insulating body in the form of a flat strip is disposed between two superimposed strips, while the upper insulating body consists of a support which has a longitudinal clearance limited by wings protective and intended to receive the conductive strips and (or) intermediate insulating body. This support also has transverse slots for the passage of contact pads.

Dans une variante préférentielle, le support isolant comporte sur sa face extérieure des évidements cylindriques aptes à créer des surfaces de réflexion.In a preferred variant, the insulating support has on its outer face cylindrical recesses capable of creating reflection surfaces.

Selon une autre forme d'exécution préféren­tielle, le corps isolant est constitué par un revêtement appliqué sur chaque bande métallique, à l'exception des plaquettes de contact.According to another preferred embodiment, the insulating body is constituted by a coating applied to each metal strip, with the exception of the contact pads.

Une forme d'exécution possible propose que chaque plaquette comporte au moins une découpure en U délimitant une languette reliée à ladite plaquette et apte à être déformée de manière à ce que son bord libre coopère avec la face du support isolant.One possible embodiment proposes that each plate includes at least one U-shaped cut-out delimiting a tongue connected to said plate and capable of being deformed so that its free edge cooperates with the face of the insulating support.

En se référant à la figure 1, la rampe est constituée par superposition d'une bande isolante de protection 1, d'une première bande conductrice 2, d'une entretoise isolante 3, d'une seconde bande conductrice 4, et d'un support isolant 5.Referring to Figure 1, the ramp is formed by superimposing an insulating protective strip 1, a first conductive strip 2, an insulating spacer 3, a second conductive strip 4, and a insulating support 5.

La bande isolante 1 présente sur sa longueur une succession d'ouvertures 11 autorisant le passage d'éléments de fixation de la rampe. La face supérieure 12 de la bande isolante 1 comporte une couche adhésive, permettant sa fixation. Dans une variante d'exécution, la face inférieure 13 peut comporter une bande adhésive, permettant la mise en place de l'ensemble.The insulating strip 1 has along its length a succession of openings 11 allowing the passage of fastening elements of the ramp. The upper face 12 of the insulating strip 1 has an adhesive layer, allowing its fixing. In an alternative embodiment, the lower face 13 may include an adhesive strip, allowing the assembly of the assembly.

La première bande conductrice 2 est destinée à être reliée, par tout moyen connu de l'homme de métier, à l'une des bornes d'une alimentation électrique, non représentée au dessin. La bande conductrice 2 comporte, à intervalles réguliers, une succession d'ouvertures 21 autorisant le passage transversal d'organes de fixation, ainsi qu'une succession de fentes 22, dont la présence sera justifiée plus loin. Les organes de connection 23 sont venus de fabrication dans la bande conductrice 2 et sont constitués par des plaquettes repliée à 90° par rapport à la bande 2, ce qui laisse subsister dans celle-ci un évidement correspondant 24. Chaque plaquette 23 pré­sente à son extrémité une ouverture ronde 25 et une décou­pure en U 26 délimitant une languette 27 reliée dans sa partie supérieure à la plaquette 23 et dont le bord libre 28 est parallèle à la ligne de pliure 29. La distance entre le bord 28 et la ligne de pliure 29 correspond à l'épaisseur cumulée de l'entretoise isolante 3, de la seconde bande conductrice 4 et de la face supérieure du support isolant 5. Les organes de connection 23 sont régulièrement espacés sur la longueur de la bande con­ductrice 2.The first conductive strip 2 is intended to be connected, by any means known to those skilled in the art, to one of the terminals of an electrical supply, not shown in the drawing. The conductive strip 2 comprises, at regular intervals, a succession of openings 21 allowing the transverse passage of fasteners, as well as a succession of slots 22, the presence of which will be justified below. The connection members 23 have come from manufacturing in the conductive strip 2 and are constituted by plates folded at 90 ° by relative to the strip 2, which leaves therein a corresponding recess 24. Each plate 23 has at its end a round opening 25 and a U-shaped cutout 26 delimiting a tongue 27 connected in its upper part to the plate 23 and whose free edge 28 is parallel to the fold line 29. The distance between the edge 28 and the fold line 29 corresponds to the cumulative thickness of the insulating spacer 3, the second conductive strip 4 and the upper face of the insulating support 5. The connection members 23 are regularly spaced along the length of the conductive strip 2.

L'entretoise isolante 3 présente une succession d'ouvertures 31 pour le passage d'éventuels organes de fixation de la rampe. Elle comporte également, à inter­valles réguliers, des fentes transversales 32 dimension­nées de manière à laisser passer les plaquettes 23.The insulating spacer 3 has a succession of openings 31 for the passage of possible fastening members of the ramp. It also comprises, at regular intervals, transverse slots 32 dimensioned so as to allow the plates 23 to pass.

La seconde bande conductrice 4 est reliée à la seconde borne de l'alimentation électrique déjà mentionnée et présente une succession d'ouvertures 41 ainsi que des dégagements transversaux 42 dont les dimensions sont supérieures à la section des plaquettes 23, pour éviter tout contact entre les bandes conductri­ces inférieure et supérieure 2 et 4.The second conductive strip 4 is connected to the second terminal of the aforementioned electrical supply and has a succession of openings 41 as well as transverse clearances 42 whose dimensions are greater than the section of the plates 23, to avoid any contact between the lower and upper conductive strips 2 and 4.

La seconde bande conductrice comporte égale­ment, à intervalles réguliers, des organes de connection constitués par des plaquettes 43 venues de fabrication dans la bande conductrice ce qui y crée des évidements correspondants 44. Chaque plaquette 43 présente à son extrémité une ouverture ronde 45 et une découpure en U 46 délimitant une languette 47 reliée dans sa partie supérieure à la plaquette 43 et dont le bord libre 48 est parallèle à la ligne de pliure 49. La distance entre le bord 48 et la ligne de pliure 49 correspond à l'épaisseur de la face supérieure du support isolant 5, de manière à ce que les ouvertures 25 et 45 soient disposées à la même hauteur, sur un axe commun.The second conductive strip also comprises, at regular intervals, connection members constituted by plates 43 which have come from manufacture in the conductive strip, which creates corresponding recesses there. Each plate 43 has at its end a round opening 45 and a cutout. U-shaped 46 delimiting a tongue 47 connected in its part greater than the plate 43 and the free edge 48 of which is parallel to the fold line 49. The distance between the edge 48 and the fold line 49 corresponds to the thickness of the upper face of the insulating support 5, so that that the openings 25 and 45 are arranged at the same height, on a common axis.

Le support isolant 5 présente une succession de passages 51 pour les organes de liaison, certains de ces passages comportant un dégagement conique 52 pour l'inser­tion de vis de fixation de la rampe sur un support non représenté au dessin, ainsi que des séries de fentes transversales 53 et 54 pour le passage des plaquettes 23 et 43 respectivement. La face supérieure 55 comporte encore des évidements cylindriques 56, dont l'utilité sera mentionnée plus loin.The insulating support 5 has a succession of passages 51 for the connecting members, some of these passages comprising a conical clearance 52 for the insertion of fastening screws of the ramp on a support not shown in the drawing, as well as series of slots transverse 53 and 54 for the passage of plates 23 and 43 respectively. The upper face 55 also has cylindrical recesses 56, the usefulness of which will be mentioned later.

La face supérieure 55 se termine, de chaque côté, par une aile 57 destinée à créer, dans la partie inférieure du support 5, un dégagement 58 destiné à recevoir les éléments 1 à 4 précédemment mentionnés, comme cela est visible à la figure 3.The upper face 55 ends, on each side, with a wing 57 intended to create, in the lower part of the support 5, a clearance 58 intended to receive the elements 1 to 4 previously mentioned, as can be seen in FIG. 3.

Dans la partie gauche de cette même figure, on a représenté en coupe l'évidement cylindrique 56, et on peut remarquer que le rayon de celui-ci est centré au milieu de l'ouverture ronde 25, de manière à créer une surface de réflexion de la source lumineuse 6. Dans ce but la surface de l'évidement cylindrique présentera un état de surface non structuré et brillant. On peut aussi prévoir un revêtement réfléchissant.In the left part of this same figure, there is shown in section the cylindrical recess 56, and it can be noted that the radius thereof is centered in the middle of the round opening 25, so as to create a reflecting surface of the light source 6. For this purpose the surface of the cylindrical recess will have an unstructured and shiny surface finish. One can also provide a reflective coating.

On notera également à la figure 3 que les ailes 57 comportent un rebord longitudinal extérieur 59, permettant la fixation de la rampe dans des clips ou dans un profilé adéquat non représentés au dessin.It will also be noted in FIG. 3 that the wings 57 have an outer longitudinal edge 59, allowing the fixing of the ramp in clips or in a suitable profile not shown in the drawing.

La rampe lumineuse de la figure 1 est représen­tée à l'état monté dans les figures 2 et 3. Le montage des éléments détaillés précédemment se fait par superpo­sition des bandes conductrices 2 et 4, séparées par l'en­tretoise isolante 3, et introduction de cet ensemble dans le dégagement central 58 du support isolant 5. L'assem­blage est réalisé en repliant les languettes 27 et 47 sur la face supérieure 55. La bande isolante de protection 1 est fixée tout au long de la bande conductrice 2, par collage par exemple.The light strip of Figure 1 is shown in the assembled state in Figures 2 and 3. The assembly of the elements detailed above is done by superposition of the conductive strips 2 and 4, separated by the insulating spacer 3, and introduction of this together in the central clearance 58 of the insulating support 5. The assembly is carried out by folding the tabs 27 and 47 on the upper face 55. The insulating protective strip 1 is fixed all along the conductive strip 2, for example by gluing .

En variante, on peut prévoir d'assembler les éléments de la rampe par des rivets traversant les ouver­tures 11, 21, 31, 41 et 51, tout en veillant à ce que les dimensions des ouvertures 21 et 41 soient suffisantes pour éviter tout contact électrique.As a variant, provision may be made to assemble the elements of the ramp by rivets passing through the openings 11, 21, 31, 41 and 51, while ensuring that the dimensions of the openings 21 and 41 are sufficient to avoid any electrical contact. .

On remarquera à la figure 2 que les ouvertures rondes 25 et 45 sont découpées en laissant subsister un rebord destiné à améliorer le contact avec le culot 61 de la lampe 62. Dans la partie gauche de la figure 2, on a partiellement représenté une lampe navette halogène 63, comportant à chaque extrémité une boucle de contact 64. Pour autoriser le montage de celle-ci, on utilisera avantageusement une cosse de contact 7 destinée à être enfichée sur les plaquettes 23 ou 43.It will be noted in FIG. 2 that the round openings 25 and 45 are cut out, leaving a rim intended to improve contact with the base 61 of the lamp 62. In the left part of FIG. 2, a shuttle lamp has been partially represented. halogen 63, comprising at each end a contact loop 64. To allow the mounting thereof, advantageously use a contact lug 7 intended to be inserted on the plates 23 or 43.

La cosse 7 est par exemple constituée par un pliage comportant une partie centrale 71 en U dont les branches 72 et 73 sont disposées de part et d'autre de la plaquette 23 ou 43. La branche 72 comporte deux ailes latérales 74 qui sont recourbées pour maintenir la cosse sur la plaquette de contact. L'extrémité 75 de la bran­che 73 est encore recourbée vers le haut d'environ 180° pour ménager un logement 76 pour la boucle 64 de contact de la lampe 63. La cosse 7 est représentée en pointillés à la figure 3 pour ne pas surcharger le dessin.The terminal 7 is for example constituted by a folding comprising a central part 71 in a U whose branches 72 and 73 are arranged on either side of the plate 23 or 43. The branch 72 has two wings 74 which are curved to maintain the terminal on the contact pad. The end 75 of the branch 73 is still curved upwards by about 180 ° to provide a housing 76 for the contact loop 64 of the lamp 63. The terminal 7 is shown in dotted lines in FIG. 3 so as not to overload the drawing.

En pratique, la distance entre une paire de plaquettes 23 et 43 destinées à recevoir un élément lumineux est d'une dimension correspondant aux longueurs standards de lampes navettes du commerce, par exemple de 40 mm et on peut prévoir de disposer les lampes tous les 55 mm. Dans le cas des lampes halogènes, les boucles de contact sont distantes d'environ 43 mm, ce qui permet d'ajouter les cavaliers 7 décrits précédemment.In practice, the distance between a pair of plates 23 and 43 intended to receive a light element is of a dimension corresponding to the standard lengths of commercial shuttle lamps, for example 40 mm and provision may be made to arrange the lamps every 55 mm. In the case of halogen lamps, the contact loops are approximately 43 mm apart, which makes it possible to add the jumpers 7 described above.

En variante, chaque plaquette peut supporter deux éléments consommateurs de courant, l'un à droite et l'autre à gauche, et dans ce cas l'écartement entre les plaquette successives correspond à la longueur de ces éléments.As a variant, each plate can support two current consuming elements, one on the right and the other on the left, and in this case the spacing between the successive plates corresponds to the length of these elements.

Les profilés du support isolant 5 et de l'en­tretoise isolante 3 sont réalisés en matière plastique. Les bandes conductrices 2 et 4 sont métalliques et de préférence en laiton. On notera que l'on peut usiner des bandes identiques et que la différence entre la bande supérieure 4 et la bande inférieure 2 provient uniquement de la localisation de la ligne de pliure 29 ou 49. Dans ce cas particulier, les bandes sont disposées en sens inverse, c'est-à-dire que les plaquettes 43 sont relevées vers la gauche tandis que les plaquettes 23 sont relevées vers la droite, dans la représentation de la figure 1. C'est pour pouvoir utiliser les mêmes bandes conductrices que la bande inférieure comporte des fentes 22, qui n'ont aucune utilité intrinsèque. En variante les bandes 2 et 4 peuvent être de largeurs différentes.The profiles of the insulating support 5 and the insulating spacer 3 are made of plastic. The conductive strips 2 and 4 are metallic and preferably made of brass. Note that identical strips can be machined and that the difference between the upper strip 4 and the lower strip 2 comes only from the location of the fold line 29 or 49. In this particular case, the strips are arranged in direction reverse, that is to say that the pads 43 are raised to the left while the pads 23 are raised to the right, in the representation of Figure 1. This is to be able to use the same conductive strips that the lower strip has slots 22, which have no intrinsic utility. As a variant, the bands 2 and 4 can be of different widths.

Dans la forme d'exécution représentée aux figures 4 à 6, on retrouve la bande isolante de protec­tion 1, la première bande conductrice 2 et la seconde bande conductrice 4, tandis que les corps isolants sont constitués par des revêtements 8 et 9 appliqués sur la bande 2 et la bande 4 respectivement.In the embodiment shown in Figures 4 to 6, there is the insulating protective strip 1, the first conductive strip 2 and the second conductive strip 4, while the insulating bodies are constituted by coatings 8 and 9 applied to the band 2 and band 4 respectively.

La face supérieure 12 de la bande 1 comporte une couche adhésive protégée par une bande détachable 14 qui sera retirée au montage de l'ensemble. La face infé­rieure 13 peut également comporter une couche adhésive protégée par une bande 15 qui sera retirée pour permettre la fixation de l'ensemble à l'emplacement désiré.The upper face 12 of the strip 1 has an adhesive layer protected by a detachable strip 14 which will be removed when the assembly is assembled. The lower face 13 may also include an adhesive layer protected by a strip 15 which will be removed to allow the assembly to be fixed at the desired location.

Comme décrit précédemment, les bandes conductri­ces 2 et 4 sont identiques et disposées en sens inverse, les fentes 22 étant siuées à droite des plaquettes 23 tandis que les fentes 42 sont disposées à gauche des pla­quettes 43. La seule différence entre les bandes est la position de la ligne de pliure 29 ou 49, visible à la figure 5.As described above, the conductive strips 2 and 4 are identical and arranged in opposite directions, the slots 22 being located to the right of the boards 23 while the slots 42 are arranged to the left of the boards 43. The only difference between the strips is the position of the fold line 29 or 49, visible in Figure 5.

Les revêtements isolants 8 et 9 sont constitués par application au four d'un émail. Il est évident que le revêtement isolant ne doit pas s'étendre sur les bords des ouvertures 25 et 45 destinées à recevoir les contacts de l'élément consommateur de courant. Comme représenté à la figure 5, le corps isolant 8 ou 9 peut être arrêté aux environs des lignes de pliure 29 et 49.The insulating coatings 8 and 9 are formed by applying an enamel to the oven. It is obvious that the insulating coating must not extend over the edges of the openings 25 and 45 intended to receive the contacts of the current-consuming element. As shown in FIG. 5, the insulating body 8 or 9 can be stopped around the fold lines 29 and 49.

En utilisant une peinture blanche pour le corps isolant supérieur 9, on obtient par la même occasion une surface réfléchissante de la lampe insérée entre les pla­quettes 23 et 43.By using a white paint for the upper insulating body 9, a reflective surface of the lamp inserted between the plates 23 and 43 is obtained at the same time.

On notera aux figures 5 et 6 que la plaquette 23, qui traverse la bande conductrice supérieure 4 et son revêtement 9 au travers de la fente 42, comporte deux découpures en U 26A et 26B définissant deux languettes 27A et 27B destinées à être repliées en sens inverse, de manière à ce que leurs bords libres 28A et 28B viennent s'appuyer de part et d'autre de la fente 42 pour assurer le montage de l'ensemble.It will be noted in FIGS. 5 and 6 that the plate 23, which crosses the upper conductive strip 4 and its covering 9 through the slot 42, has two U-shaped cutouts 26A and 26B defining two tabs 27A and 27B intended to be folded in direction reverse, so that their free edges 28A and 28B come to bear on either side of the slot 42 to ensure the assembly of the assembly.

En variante, les deux languettes peuvent être repliées du même côté de la plaquette. De plus, les languettes peuvent être réalisées également sur les bords de la plaquette plutôt qu'en son centre.As a variant, the two tabs can be folded back on the same side of the plate. In addition, the tongues can also be produced on the edges of the plate rather than at its center.

Il va sans dire que l'invention n'est pas limitée à une rampe d'éclairage au moyen d'ampoules, et que l'on peut en variante prévoir d'utiliser le principe de l'emboitage de deux bandes conductrices dans un pro­filé plastique en adaptant l'écartement et les formes des éléments de connection à d'autres sources lumineuses ou tous éléments consommateurs de courant.It goes without saying that the invention is not limited to a light bar by means of bulbs, and that it is alternatively possible to provide for using the principle of fitting two conductive strips into a profile. plastic by adapting the spacing and the shapes of the connection elements to other light sources or all current consuming elements.

On peut aussi par exemple, sans sortir du cadre de la présente invention, insérer entre les plaquettes conductrices des adaptateurs ou des supports conducteurs de lampes d'éclairage à contact fourchettes, par exemple des lampes à halogène. Ces supports peuvent en variante autoriser l'orientation d'éléments lumineux tels que des spots.It is also possible, for example, without departing from the scope of the present invention, to insert adapters or conductive supports between fork contact lighting lamps, for example halogen lamps, between the conductive plates. These supports may alternatively allow the orientation of light elements such as spotlights.

De plus, le nombre de bandes conductrices n'est pas limité à deux, un nombre supérieur permettant d'obte­nir une rampe avec plusieurs intensités d'éclairage.In addition, the number of conductive strips is not limited to two, a higher number making it possible to obtain a ramp with several lighting intensities.
