Abstract

The invention relates to a lamp holder for a motor vehicle lighting and/or signaling module or device. The holder includes a wall 104 of a housing 102 that has an opening 108, and a metal sheet 106 that also has an opening 108 and is attached to said wall 102 by means of overmolding 116. The overmolding makes it possible to ensure strict tolerances on the functional assembly dimension and, consequently, ensure locking torque within a low-value range. The sheet 106 can be placed directly against the inner surface of the wall 104, such that the means for attaching the base of the lamp to the metal sheet presses the sheet 106 against the wall 104. The invention also relates to a signaling or lighting module or device provided with said holder and to a corresponding method for creating the holder.

Description

SUPPORT DE LAMPE POUR MODULE OU DISPOSITIF D'ECLAIRAGE ET/OU DE SIGNALISATION POUR VEHICULE, MODULE, BOITIER ET PROCEDE CORRESPONDANTS  LAMP SUPPORT FOR MODULE OR LIGHTING AND / OR SIGNALING DEVICE FOR VEHICLE, MODULE, HOUSING AND METHOD THEREOF
L'invention a trait à un support de lampe pour module ou dispositif d'éclairage et/ou de signalisation pour véhicule. Plus particulièrement, l'invention a trait à un support de lampe avec culot, telle qu'une lampe avec des ergots de verrouillage, par exemple une lampe H8 ou une lampe H1 1 . L'invention a trait également à un module et à un boîtier de dispositif d'éclairage et/ou de signalisation équipé dudit support. L'invention a trait également à un procédé d'assemblage d'un tel support de lampe. Les figures 1 et 2 illustrent un dispositif d'éclairage connu. La figure 1 illustre une vue en plan du boîtier. La figure 2 est une vue en coupe du boîtier selon un plan longitudinal de la figure 1 , la coupe étant illustrée par les flèches de la figure 1 . A la figure 2, une lampe montée sur son support est également représentée. Le dispositif d'éclairage illustré est un projecteur du type antibrouillard avant. Il comprend un boîtier 2 de section transversale généralement circulaire. Le fond du boîtier 2 comprend une paroi 4 comprenant une portion généralement plane. La paroi 4 comprend un orifice 8 destiné à recevoir le culot d'une lampe. Une pièce métallique faite à partir d'une tôle 6 est disposée sur la paroi, du côté interne de la paroi, c'est-à- dire à l'intérieur du volume défini par le boîtier et la glace 3 transparente et/ou translucide servant de fermeture à ce boîtier. The invention relates to a lamp holder for a module or a lighting and / or signaling device for a vehicle. More particularly, the invention relates to a lamp holder with a base, such as a lamp with locking lugs, for example an H8 lamp or a H1 lamp 1. The invention also relates to a module and a lighting device housing and / or signaling equipped with said support. The invention also relates to a method of assembling such a lamp holder. Figures 1 and 2 illustrate a known lighting device. Figure 1 illustrates a plan view of the housing. FIG. 2 is a sectional view of the housing along a longitudinal plane of FIG. 1, the section being illustrated by the arrows of FIG. In Figure 2, a lamp mounted on its support is also shown. The illustrated lighting device is a front fog lamp. It comprises a housing 2 of generally circular cross section. The bottom of the housing 2 comprises a wall 4 comprising a generally flat portion. The wall 4 comprises an orifice 8 for receiving the base of a lamp. A metal part made from a sheet 6 is disposed on the wall, on the inner side of the wall, that is to say within the volume defined by the housing and the transparent and / or translucent ice 3 closing the housing.
La pièce métallique 6 comprend également un orifice correspondant à celui de la paroi 4. La découpe de la pièce métallique formant l'orifice présente un profil adapté au culot de la lampe. En effet, la plupart des lampes à incandescence de projecteur telle que la lampe 20 qui est illustrée à la figure 2 ont un culot 22 avec des ergots de verrouillage, à savoir que leur culot 22 comprend plusieurs picots ou ergots 24 répartis sur la circonférence dudit culot. Ces picots ou ergots 24 sont souvent au nombre de trois. Ils sont souvent disposés de manière non régulière sur la circonférence du culot de façon à former un détrompeur qui n'autorise le montage d'une seule lampe, soit H8 ou H1 1 . Le profil de l'ouverture 8 du fond de boîtier comprend plusieurs rampes 14 destinées à coopérer avec les picots ou ergots 24. The metal part 6 also comprises a hole corresponding to that of the wall 4. The cutting of the metal part forming the orifice has a profile adapted to the base of the lamp. Indeed, most projector incandescent lamps such as the lamp 20 which is illustrated in Figure 2 have a base 22 with locking lugs, namely that their base 22 comprises a plurality of pins or lugs 24 distributed on the circumference of said pellet. These pins or lugs 24 are often three in number. They are often arranged nonregularly on the circumference of the base so as to form a polarizer that allows the mounting of a single lamp, either H8 or H1 1. The profile of the opening 8 of the housing base comprises several ramps 14 intended to cooperate with the pins or lugs 24.
La pièce métallique 6 est fixée à la paroi 4 au moyen des deux tétons 10 et 12 moulés avec la paroi 4. La pièce métallique comprend des ouvertures correspondantes destinées à recevoir les tétons 10 et 12. Lors de l'assemblage, la pièce métallique est mise en place contre la paroi par un mouvement de mise en correspondance des orifices avec les tétons respectifs suivi d'un mouvement de translation le long des tétons. Les orifices de la pièce métallique comprennent des moyens de retenue de la pièce par rapport aux tétons. Ces moyens sont visibles à la figure 1 . On peut voir que l'orifice supérieur recevant le téton 10 comprend deux languettes orientées généralement horizontalement et destinées à pincer le téton. La zone entourant l'orifice inférieur recevant le téton 12 est divisée en quatre secteurs formant quatre languettes destinées également à pincer le téton 12. Comme cela est visible à la figure 2, les tétons sont généralement coniques de manière à faciliter l'engagement de la pièce métallique. Le montage de la pièce métallique 6 requiert cependant un effort croissant jusqu'à ce qu'elle vienne en contact avec la paroi 4. En fonction de l'effort que le monteur appliquera, la pièce métallique peut ne pas être totalement en contact avec la paroi, résultant en une variation de la cote fonctionnelle e illustrée à la partie agrandie de la figure 2. Cette cote fonctionnelle correspond à l'épaisseur de la paroi 4 additionnée de l'épaisseur de la tôle de la pièce métallique 6 et d'une éventuelle surcote liée à un bossage autour des tétons. De plus, la présence même des languettes de blocage coopérant avec les tétons génère un léger retour de la pièce métallique lors de son montage. Un placage parfait de la pièce métallique sur la paroi n'est donc pas possible, résultant en une tolérance importante sur la cote fonctionnelle e. The metal part 6 is fixed to the wall 4 by means of the two studs 10 and 12 molded with the wall 4. The metal part comprises openings corresponding to receiving the pins 10 and 12. During assembly, the metal piece is placed against the wall by a movement of matching the orifices with the respective nipples followed by a translational movement along the nipples . The orifices of the metal part comprise means for retaining the part with respect to the pins. These means are visible in FIG. It can be seen that the upper orifice receiving the stud 10 comprises two tongues oriented generally horizontally and intended to grip the stud. The area surrounding the lower orifice receiving the pin 12 is divided into four sectors forming four tongues also for pinching the pin 12. As can be seen in Figure 2, the pins are generally conical so as to facilitate the engagement of the metal part. The mounting of the metal part 6, however, requires increasing effort until it comes into contact with the wall 4. Depending on the effort that the fitter will apply, the metal part may not be fully in contact with the wall, resulting in a variation of the functional dimension e illustrated in the enlarged portion of FIG. 2. This functional dimension corresponds to the thickness of the wall 4 plus the thickness of the sheet of the metal part 6 and a possible surge linked to a boss around the nipples. In addition, the very presence of the locking tabs cooperating with the nipples generates a slight return of the metal part during its assembly. Perfect veneering of the metal part on the wall is therefore not possible, resulting in a significant tolerance on the functional dimension e.
La tolérance sur la cote fonctionnelle e a pour effet de rendre le montage de la lampe difficile. En effet, les rampes 14 de contact avec les ergots 24 du culot 22 de la lampe s'en retrouvent plus éloignées de la surface extérieure de la paroi 4 que prévu initialement. Malgré la présence d'un joint souple 26 au niveau de la surface d'appui de la lampe sur la paroi 4, un couple plus important peut alors être requis pour le montage de la lampe. Or, le corps arrière 28 de la lampe n'étant pas particulièrement ergonomique et, de plus, l'accessibilité à cette zone dans le véhicule n'étant pas toujours bonne, un couple important à appliquer lors du montage de la lampe peut causer de réels problèmes de productivité. En pratique, pour une lampe H1 1 , la cote nominale e est de 2.85 mm. Compte tenu de tolérances intrinsèques à la fabrication de la paroi 4 et de la pièce métallique 6, la cote e peut dépasser la valeur de 3.1 mm. Pour de telles valeurs, le couple de verrouillage dépasse 1 .5 Nm. Or le couple normal de montage de la lampe est de préférence de 1 .1 Nm à 1 ,5 Nm maxi. The tolerance on the functional dimension has the effect of making the mounting of the lamp difficult. Indeed, the ramps 14 of contact with the lugs 24 of the base 22 of the lamp are found more distant from the outer surface of the wall 4 as originally intended. Despite the presence of a flexible seal 26 at the bearing surface of the lamp on the wall 4, a larger torque may then be required for mounting the lamp. However, the rear body 28 of the lamp is not particularly ergonomic and, moreover, the accessibility to this area in the vehicle is not always good, a large torque to apply when mounting the lamp can cause real productivity problems. In practice, for a lamp H1 1, the nominal dimension e is 2.85 mm. Given intrinsic tolerances in the manufacture of the wall 4 and the metal part 6, the dimension e may exceed the value of 3.1 mm. For such values, the locking torque exceeds 1.5 Nm. However, the normal mounting torque of the lamp is preferably 1 .mu.m to 1.5 Nm max.
De plus, la nature même du montage est susceptible d'éloigner la pièce métallique 6 de la paroi 4. En effet, lors du montage, le culot 22 de la lampe 20 est inséré dans l'orifice 8 et ensuite orienté de manière à ce que les ergots 24 correspondent au profil de l'orifice 8. Durant cette opération, l'opérateur peut être tenté d'exercer un effort d'insertion de la lampe croyant que cette dernière est en correspondance avec l'orifice alors que ce n'est pas le cas. Cet effort sera repris par la pièce métallique et peut l'éloigner de la paroi 4. II est également connu de fixer le porte-lampe à la paroi d'un module ou d'un dispositif d'éclairage et/ou de signalisation par simple vissage. Ce type de montage est plus coûteux en temps d'assemblage mais permet un meilleur placage du porte- lampe sur la paroi. Des fûts de vissage doivent alors être prévus au niveau de la paroi. Ils sont souvent sujets à des problèmes de porosité liés au procédé d'injection de plastique. Ces défauts de porosité peuvent provoquer des rejets de pièces en fabrication ou de casses lors du montage par vissage lorsque ces défauts n'ont pas été détectés. In addition, the nature of the assembly is likely to move the metal part 6 away from the wall 4. Indeed, during assembly, the base 22 of the lamp 20 is inserted into the orifice 8 and then oriented so that that the lugs 24 correspond to the profile of the orifice 8. During this operation, the operator may be tempted to exert a force insertion of the lamp believing that the latter is in correspondence with the orifice while n ' is not the case. This effort will be taken up by the metal part and can move it away from the wall 4. It is also known to fix the lamp holder to the wall of a module or a lighting and / or signaling device by simple screwing. This type of assembly is more expensive in assembly time but allows a better veneer of the lamp holder on the wall. Screw drums must then be provided at the wall. They are often subject to porosity problems related to the plastic injection process. These porosity defects can cause rejects of parts in manufacture or breakages during the assembly by screwing when these defects have not been detected.
L'invention a pour objectif de proposer une solution au problème de tolérances trop larges sur la cote fonctionnelle discutée précédemment et sur la variation trop grande du couple de montage de la lampe sur le support. The object of the invention is to propose a solution to the problem of excessively wide tolerances on the functional dimension discussed previously and on the excessive variation of the mounting torque of the lamp on the support.
L'invention a pour objet un support de lampe avec culot, pour module ou dispositif d'éclairage et/ou de signalisation, comprenant: un corps en matière plastique; une pièce métallique avec un orifice destiné à recevoir le culot de la lampe, la pièce métallique étant fixée au corps; remarquable en ce que la pièce métallique est fixée au corps par surmoulage. The invention relates to a lamp holder with a base, for a module or lighting and / or signaling device, comprising: a body made of plastic material; a metal part with an orifice for receiving the base of the lamp, the metal part being fixed to the body; remarkable in that the metal part is fixed to the body by overmolding.
La fixation de la pièce métallique au corps est assurée préférentiellement majoritairement, plus préférentiellement encore exclusivement, par surmoulage. Fixing the metal part to the body is preferably provided mainly, more preferentially still exclusively, by overmolding.
Selon un mode avantageux de l'invention, le surmoulage est situé au niveau d'au moins une partie du bord de la périphérie de la pièce métallique. Le surmoulage peut s'étendre sur une majeure partie du périmètre de la pièce métallique, voire sur sa totalité. Préférentiellement, le corps est surmoulé sur la pièce métallique. According to an advantageous embodiment of the invention, the overmoulding is located at at least a part of the edge of the periphery of the metal part. The overmolding may extend over a major part of the perimeter of the metal part, or even on its entirety. Preferably, the body is overmolded on the metal part.
La pièce métallique peut prendre diverses formes. Elle peut être généralement circulaire, éventuellement avec au moins une portion non circulaire afin de la lier mécaniquement en rotation via le surmoulage. Selon un autre mode avantageux de l'invention, la pièce métallique comprend au moins un trou de fixation au corps, le surmoulage étant au niveau du trou et/ou d'au moins un des trous de fixation. Ce trou ou ces trous sont préférentiellement disposés latéralement par rapport à l'orifice recevant le culot de la lampe. The metal part can take various forms. It may be generally circular, possibly with at least one non-circular portion to mechanically link it in rotation via the overmolding. According to another advantageous embodiment of the invention, the metal part comprises at least one attachment hole to the body, the overmolding being at the level of the hole and / or at least one of the fixing holes. This hole or these holes are preferably arranged laterally with respect to the orifice receiving the base of the lamp.
Selon un encore autre mode avantageux de l'invention, la portion de la pièce métallique autour de l'orifice est généralement plane, la pièce métallique étant préférentiellement faite à partir d'une tôle. L'épaisseur de la tôle est comprise entre 0.5 et 2 mm, préférentiellement entre 0.5 et 1 .5 mm, plus préférentiellement entre 0.5 et 1 mm. According to another advantageous embodiment of the invention, the portion of the metal part around the orifice is generally flat, the metal part being preferably made from a sheet. The thickness of the sheet is between 0.5 and 2 mm, preferably between 0.5 and 1.5 mm, more preferably between 0.5 and 1 mm.
Selon un encore autre mode avantageux de l'invention, le corps comprend une paroi avec un orifice et contre laquelle la pièce métallique est en contact, la pièce métallique étant préférentiellement en contact direct avec la paroi. According to yet another advantageous embodiment of the invention, the body comprises a wall with an orifice and against which the metal part is in contact, the metal part being preferably in direct contact with the wall.
Selon un encore autre mode avantageux de l'invention, la paroi comprend au moins un élément support destiné à supporter la pièce métallique à distance de ladite paroi, le surmoulage étant préférentiellement avec le ou au moins un des éléments support, c'est-à-dire que l'élément support est surmoulé sur la pièce métallique. Dans ce cas, ledit corps est préférentiellement un réflecteur de module d'éclairage. According to another advantageous embodiment of the invention, the wall comprises at least one support element intended to support the metal part at a distance from said wall, the overmoulding being preferentially with the or at least one of the support elements, that is to say that is, the support element is overmolded on the metal part. In this case, said body is preferably a lighting module reflector.
Selon un encore autre mode avantageux de l'invention, le contour de l'orifice de la pièce métallique est configuré de manière à détromper le culot de la lampe. According to yet another advantageous embodiment of the invention, the outline of the orifice of the metal part is configured in such a way as to undo the base of the lamp.
Selon un encore autre mode avantageux de l'invention, le contour de l'orifice dans le boîtier est configuré de manière à détromper le culot de la lampe. According to yet another advantageous embodiment of the invention, the outline of the orifice in the housing is configured so as to undo the base of the lamp.
De préférence, le corps comprend des rampes évoluant du bord de l'orifice dans le boîtier jusqu'à la pièce métallique, permettant ainsi d'amener les ergots de verrouillage sur la pièce métallique, lorsque la lampe est verrouillée, notamment en rotation sur le corps. L'invention a également pour objet un module d'éclairage et/ou de signalisation comprenant un support de lampe, remarquable en ce que le support de lampe est conforme à l'invention. Préférentiellement, le support de lampe est un réflecteur. Preferably, the body comprises ramps moving from the edge of the orifice in the housing to the metal part, thus making it possible to bring the locking lugs to the metal part, when the lamp is locked, in particular in rotation on the body. The invention also relates to a lighting and / or signaling module comprising a lamp holder, which is remarkable in that the lamp holder is in accordance with the invention. Preferably, the lamp holder is a reflector.
L'invention a également pour objet un boîtier de dispositif d'éclairage et/ou de signalisation comprenant un support de lampe, caractérisé en ce que le support de lampe est conforme à l'invention. Préférentiellement, le support de lampe et le boîtier forment une seule pièce, notamment obtenue par moulage. The invention also relates to a lighting device and / or signaling device comprising a lamp holder, characterized in that the lamp holder is in accordance with the invention. Preferably, the lamp support and the housing form a single piece, in particular obtained by molding.
L'invention a également pour objet un dispositif d'éclairage et/ou de signalisation comprenant un boîtier ou un module d'éclairage et/ou de signalisation selon l'invention. The invention also relates to a lighting and / or signaling device comprising a housing or a lighting module and / or signaling according to the invention.
L'invention est particulièrement adaptée pour des dispositifs d'éclairage et/ou de signalisation dont le boîtier a des dimensions de largeur, longueur et profondeurs inférieures à 15 cm, et même inférieures à 10 cm. La présente invention permet en effet une solution pratique, dans laquelle la plaque métallique fait écran thermique entre la source lumineuse et le fond du boîtier, permettant de protéger ce dernier de la chaleur dégagée par la source lumineuse, notamment une lampe. Selon une variante de réalisation, ce dispositif d'éclairage et/ou de signalisation est un dispositif d'éclairage anti-brouillard. Ceci est avantageux car les anti-brouillards sont souvent de petite taille en comparaison avec les projecteurs. L'invention a également pour objet un procédé de fabrication d'un support de lampe avec culot, pour module ou dispositif d'éclairage et/ou de signalisation, comprenant les étapes suivantes: (a) préparation d'un corps en matière plastique; (b) mise en place sur le corps d'une pièce métallique avec un orifice destiné à recevoir le culot de la lampe, caractérisé par l'étape suivante (c) surmoulage de matière plastique sur la pièce métallique et le corps en vue de sa fixation au corps. The invention is particularly suitable for lighting and / or signaling devices whose housing has dimensions of width, length and depths less than 15 cm, and even less than 10 cm. The present invention indeed provides a practical solution in which the metal plate is a heat shield between the light source and the bottom of the housing, to protect the latter from the heat released by the light source, including a lamp. According to an alternative embodiment, this lighting and / or signaling device is an anti-fog lighting device. This is advantageous because the fog lamps are often small in comparison with the projectors. The invention also relates to a method of manufacturing a lamp holder with a base, for a module or lighting and / or signaling device, comprising the following steps: (a) preparation of a plastic body; (b) placing on the body of a metal part with an orifice intended to receive the base of the lamp, characterized by the following step (c) overmoulding of plastic material on the metal part and the body in view of its attachment to the body.
L'invention a également pour objet un procédé de fabrication d'un support de lampe avec culot, pour module ou dispositif d'éclairage et/ou de signalisation, comprenant les étapes suivantes: (a) mise à disposition d'un moule pour le moulage par injection de matière plastique du support; remarquable par les étapes suivantes: (b) mise en place dans le moule d'une pièce métallique avec un orifice destiné à recevoir le culot de la lampe; (c) injection de la matière plastique de manière à former le corps et à au moins partiellement surmouler la pièce métallique en vue de sa fixation au corps. Ce procédé est plus simple de réalisation et plus économique. The subject of the invention is also a method for manufacturing a lamp holder with a base, for a module or lighting and / or signaling device, comprising the following steps: (a) provision of a mold for the plastic injection molding of the support; remarkable by the following steps: (b) placing in the mold a metal part with a hole intended to receive the base of the lamp; (c) injection of the plastic material to form the body and to less partially overmold the metal piece for attachment to the body. This process is simpler and more economical.
Préférentiel lement, le support de lampe obtenu par le procédé de fabrication selon l'invention, est un support conforme à l'invention. Toutes les caractéristiques décrites précédemment en relation avec le support et le module ou le dispositif sont également divulguées en combinaison avec les deux procédés ci-avant. Preferably, the lamp support obtained by the manufacturing method according to the invention is a support according to the invention. All the characteristics described above in relation to the support and the module or the device are also disclosed in combination with the two methods above.
Le surmoulage de la pièce métallique sur le corps ou plus précisément la paroi du support permet d'assurer une fixation de cette dernière à faible coût avec toutefois une plus grande précision quant à sa position. Cette tolérance plus serrée sur la position de la pièce métallique permet d'atteindre un positionnement plus précis de la lampe et, plus particulièrement, une tolérance plus serrée sur la cote fonctionnelle de montage de la lampe. L'obtention d'une tolérance serrée au niveau de la cote fonctionnelle dont dépend le couple de verrouillage de la lampe va permettre d'obtenir une plage de couple de verrouillage sensiblement plus réduite et, partant, un couple de verrouillage nécessaire mieux contrôlé. Il en résulte un montage rendu plus facile notamment sur les lignes de production ainsi qu'en service après vente. Ce montage plus facile est particulièrement avantageux lorsque l'accessibilité à la partie arrière du dispositif d'éclairage et/ou de signalisation est mauvaise. Cette situation est courante notamment pour les projecteurs antibrouillard. De plus, la maîtrise du couple de serrage va réduire les risques d'entrées d'eau intempestives. The over-molding of the metal part on the body or more precisely the wall of the support makes it possible to secure the latter at low cost, but with greater precision as to its position. This tighter tolerance on the position of the metal part makes it possible to achieve a more precise positioning of the lamp and, more particularly, a tighter tolerance on the functional dimension of mounting of the lamp. Obtaining a tight tolerance in the functional dimension on which the lamp locking torque depends will make it possible to obtain a substantially smaller locking torque range and hence a much better controlled locking torque. The result is easier editing, especially on production lines and after-sales service. This easier assembly is particularly advantageous when the accessibility to the rear part of the lighting and / or signaling device is poor. This situation is common especially for fog lamps. In addition, the control of the tightening torque will reduce the risk of untimely water ingress.
Le surmoulage permet également de s'acquitter des fûts de vissage nécessaires pour la fixation de la pièce métallique sur des réflecteurs injectés. Le surmoulage permet de s'acquitter des difficultés liées à la porosité de ces dômes et au rejet de pièces. De plus, la manipulation manuelle des réflecteurs, notamment les réflecteurs aluminés, en vue du vissage requiert un soin particulier. Le surmoulage permet également de s'acquitter de ces difficultés. The overmolding also makes it possible to discharge the screwing drums necessary for fixing the metal part on injected reflectors. The overmolding makes it possible to fulfill the difficulties related to the porosity of these domes and to the rejection of parts. In addition, manual handling of reflectors, including aluminized reflectors, for screwing requires special care. Overmolding also makes it possible to fulfill these difficulties.

Certains éléments constitutifs des dispositifs illustrés aux figures 3 à 7 correspondent à ceux des figures 1 et 2. Une numérotation cohérente a été adoptée pour désigner ces différents éléments sachant que les signes de référence de la figure 3 correspondent à ceux de la figure 1 à cette différence qu'ils sont majorés de 100. Il en va de même pour la figure 5 où ils sont majorés de 1 .000, pour la figure 6 où ils sont majorés de 10.000 et pour la figure 7 où ils sont majorés de 100.000. Des numéros spécifiques à chaque exemple de réalisation ont été employés pour désigner les éléments n'étant pas présents aux figures 1 et 2.  - Figure 7 is a perspective view of the rear portion of a lighting module similar to that of Figure 6 and provided with a lamp holder according to a fourth embodiment of the invention. Some elements constituting the devices illustrated in FIGS. 3 to 7 correspond to those of FIGS. 1 and 2. A coherent numbering has been adopted to designate these various elements, knowing that the reference signs of FIG. 3 correspond to those of FIG. the difference is that they are increased by 100. The same goes for figure 5 where they are increased by 1 000, for figure 6 where they are increased by 10.000 and for figure 7 where they are increased by 100.000. Numbers specific to each exemplary embodiment have been used to designate elements not present in FIGS. 1 and 2.
La figure 3 illustre un boîtier 102 de projecteur similaire à celui de la figure 1 . Il définit un volume intérieur avec une glace transparente (non visible) destiné à le fermer. Il comprend une paroi 104 au fond du volume en question. La paroi comprend un orifice 108 destiné à recevoir une lampe. La lampe est du type à incandescence avec un culot avec des ergots de verrouillage. Une pièce métallique 106 est disposée sur la paroi, plus précisément sur la face intérieure de la paroi 104. Ladite pièce métallique 106 est généralement plate et faite à partir d'une tôle d'une épaisseur de l'ordre de 0.8 mm. Elle comprend un orifice dont le profil est adapté à la lampe à supporter. La lampe à supporter peut être du type H1 1 ou de tout autre type avec culot avec des ergots de verrouillage. Le profil de l'ouverture pratiquée dans la paroi 104 du boîtier comprend plusieurs rampes 1 14 avec lesquelles les ergots du culot de la lampe vont coopérer, de sorte que grâce à leur profil, les ergots seront amenés en appui contre la pièce métallique 106 lorsque la lampe sera tournée au cours du verrouillage. FIG. 3 illustrates a projector box 102 similar to that of FIG. 1. It defines an interior volume with a transparent ice (not visible) intended to close it. It comprises a wall 104 at the bottom of the volume in question. The wall comprises an orifice 108 for receiving a lamp. The lamp is of the incandescent type with a base with locking lugs. A metal piece 106 is disposed on the wall, more precisely on the inner face of the wall 104. Said metal part 106 is generally flat and made from a sheet having a thickness of about 0.8 mm. It comprises an orifice whose profile is adapted to the lamp to be supported. The lamp to be supported can be of type H1 1 or any other type with a base with locking lugs. The profile of the opening made in the wall 104 of the housing comprises several ramps 1 14 with which the pins of the base of the lamp will cooperate, so that thanks to their profile, the lugs will be brought in support against the metal part 106 when the lamp will be turned during the locking.
La figure 3 comprend une vue en coupe du boîtier selon l'axe de coupe identifiée par les flèches. Sur cette vue en coupe, on peut observer que la pièce métallique 106 est fixée à la paroi 104 par un surmoulage 1 16 au niveau du bord extérieur de la pièce 106. Le surmoulage en question peut être un moulage d'insert, c'est-à-dire consistant à placer la pièce métallique dans un moule et à injecter le matériau plastique autour de ladite pièce. La vue agrandie du bord de l'orifice 108 de la figure 3 illustre bien les tolérances plus faibles obtenues pour la cote fonctionnelle e de montage de la lampe sur le support ainsi formé. La pièce métallique 106 est bien en contact total avec la paroi 104, et le surmoulage 1 16 sur au moins une partie du bord extérieur de la pièce métallique 106 assure un maintien inconditionnel de celle-ci contre la paroi, et, partant, une tolérance très fine sur la cote e correspondant à la somme des épaisseurs de la paroi 104 et de la pièce métallique 106. Pour une lampe H1 1 ou H8, la cote e est par exemple de 2.85 mm. Cette cote peut varier dans une tolérance de 0.5 mm notamment en raison de l'influence des tolérances du plastique infecté et de la tôle. Figure 3 comprises a sectional view of the housing along the axis of section identified by the arrows. In this sectional view, it can be seen that the metal part 106 is fixed to the wall 104 by an overmolding 1 16 at the outer edge of the part 106. The overmolding in question may be an insert molding, it is that is, placing the metal part in a mold and injecting the plastic material around said part. The enlarged view of the edge of the orifice 108 of FIG. 3 illustrates the lower tolerances obtained for the functional dimension e of mounting the lamp on the support thus formed. The metal part 106 is in full contact with the wall 104, and the overmolding 1 16 on at least a portion of the outer edge of the metal part 106 ensures unconditional retention thereof against the wall, and hence a tolerance very thin on the dimension e corresponding to the sum of the thicknesses of the wall 104 and the metal part 106. For a lamp H1 1 or H8, the dimension e is for example 2.85 mm. This dimension may vary within a tolerance of 0.5 mm, in particular because of the influence of the tolerances of the infected plastic and the sheet.
Dans le cas précis de l'exemple de réalisation de la figure 3, le surmoulage 1 16 s'étend sur toute la circonférence de la pièce métallique 106 et recouvre partiellement la surface visible de ladite pièce. La figure 4 illustre la pièce métallique seule 106. Elle est généralement plane et présente un contour circulaire 120 avec toutefois deux sections droites opposées 1 18. Ces sections droites 1 18 permettent d'assurer une liaison mécanique en rotation de la pièce 106 par rapport au boîtier. En effet, bien que le surmoulage assure une certaine cohésion entre la matière plastique moulée et la matière métallique de la pièce, un glissement pourrait toutefois avoir lieu, notamment lors de l'application de couples de montage de la lampe exagérés. Cette forme circulaire du contour 120 n'est pas limitative, elle pourrait être notamment rectangulaire. II est à noter que le surmoulage qui vient d'être décrit ne doit pas nécessairement s'étendre sur toute la circonférence. Il en va de même pour la pièce métallique qui peut prendre diverses formes et contours. La figure 5 illustre un deuxième exemple de réalisation de l'invention. Il s'agit d'un boîtier 1002 similaire à celui du premier exemple de réalisation de la figure 3. Seule la pièce métallique 1006 supportant la lampe et les surmoulages 1016 sont différents. Les explications relatives au boîtier qui ont été faites en relation avec ce premier mode de réalisation, hormis celles qui sont spécifiques à la pièce métallique et au surmoulage, s'appliquent ici également. In the specific case of the embodiment of Figure 3, overmolding 1 16 extends over the entire circumference of the metal part 106 and partially covers the visible surface of said part. FIG. 4 illustrates the single metal part 106. It is generally flat and has a circular contour 120 with however two opposite straight sections 1 18. These straight sections 1 18 make it possible to ensure a mechanical connection in rotation of the part 106 with respect to the housing. Indeed, although the overmolding ensures a certain cohesion between the molded plastic material and the metal material of the workpiece, slippage could nevertheless occur, especially when applying exaggerated lamp mounting torques. This circular shape of the outline 120 is not limiting, it could be in particular rectangular. It should be noted that the overmolding that has just been described does not necessarily have to extend over the entire circumference. The same goes for the metal part which can take various forms and contours. FIG. 5 illustrates a second exemplary embodiment of the invention. It is a case 1002 similar to that of the first embodiment of FIG. 3. Only the metal part 1006 supporting the lamp and the overmoldings 1016 are different. The explanations relating to the box which have been made in connection with this first embodiment, except those which are specific to the metal part and the overmoulding, also apply here.
La pièce métallique 1006 est de forme généralement rectangulaire, les bords au niveau des petits côtés du rectangle présentant toutefois un profil avec un profil irrégulier 1019. Les bords latéraux au niveau des grands côtés du rectangle présentent des tronçons 1018 de tôle pliés à 90° par rapport au plan général de la pièce, ces bords ayant pour fonction de rigidifier la pièce métallique. La pièce métallique est fixée à la paroi 1004 du boîtier 1002 par surmoulage de matière sur la pièce métallique ainsi qu'au travers d'au moins un orifice de la pièce métallique. Dans l'exemple illustré, il y a six orifices mais cet exemple n'est pas limitatif. La vue en coupe de la figure 5 illustre bien les orifices centraux, c'est-à-dire situés sur l'axe de coupe. Ces orifices sont remplis de la matière plastique surmoulée 1016 sur la pièce métallique 1006. The metal part 1006 is of generally rectangular shape, the edges at the small sides of the rectangle, however, having a profile with an irregular profile 1019. The side edges at the long sides of the rectangle have sections 1018 of sheet metal bent at 90 ° by relative to the general plane of the part, these edges having the function of stiffening the metal part. The metal part is fixed to the wall 1004 of the casing 1002 by over-molding of material on the metal part as well as through at least one orifice of the metal part. In the illustrated example, there are six orifices, but this example is not limiting. The sectional view of Figure 5 illustrates the central orifices, that is to say located on the cutting axis. These orifices are filled with the overmolded plastic material 1016 on the metal part 1006.
Tout comme pour le premier exemple de réalisation, le surmoulage peut être un moulage d'insert, c'est-à-dire consistant à placer la pièce métallique dans un moule et à injecter le matériau plastique autour de ladite pièce. Tout comme pour le premier exemple de réalisation, la pièce métallique 1006 est disposée sur la face interne de la paroi 1004, c'est-à-dire la face délimitant la cavité formée par le boîtier et destiné à recevoir la lampe. Cette dernière est insérée à partir de l'extérieur du boîtier au travers de l'orifice 1008 de manière à venir prendre appui sur la face externe de la paroi 1004. Les moyens de fixation de la lampe, à savoir les ergots faisant saillie du culot (voir discussion de la figure 2), coopèrent avec la pièce métallique 1006, plus particulièrement notamment avec les rampes 1014 du boîtier, de manière à exercer un effort de traction sur le culot de la lampe, la maintenant en appui stable sur la face externe de la paroi 1002. Le nombre et l'agencement des orifices de surmoulage peuvent bien sûr varier de l'exemple qui vient d'être décrit. En effet, un nombre plus réduit d'orifices ainsi qu'éventuellement un agencement différent de ces derniers peut être envisagé. La figure 6 illustre un troisième exemple de réalisation de l'invention. Contrairement aux exemples précédents, la paroi 10004 supportant la pièce métallique n'est plus celle d'un boîtier mais celle d'un module d'éclairage 10002, destiné à être placé dans un dispositif d'éclairage, tel qu'un projecteur. Sur l'exemple illustré en figure 6, il s'agit d'un réflecteur. Tout comme pour le premier et le deuxième exemples de réalisation, le surmoulage peut être un moulage d'insert, c'est-à-dire consistant à placer la pièce métallique dans un moule et à injecter le matériau plastique autour de ladite pièce comportant la paroi de support 10004. De plus, la pièce métallique 10006 n'est plus disposée directement contre la paroi 10004 mais contre des éléments supports 10005. Ces éléments supports 10005 sont en saillie de la paroi 10004 de sorte que la pièce métallique 10006 est à distance de la dite paroi 10004. La pièce métallique 10006 servant de support de la lampe 10020 est non plane. Elle comprend une partie centrale de forme généralement cylindrique ainsi qu'une partie généralement plane avec deux « oreilles » venant en appui sur les éléments de support 10005. Chacune des parties latérales formant des excroissances latérales, pattes ou « oreilles », comprend un ou plusieurs orifices destinés à recevoir un pion ou plusieurs pions 10016, respectivement, surmoulés. Dans le cas précis de la figure 7, chacune des pattes comprend un seul pion surmoulé. Les éléments support 10005 peuvent comprendre un orifice de géométrie choisie, destiné à recevoir le pion lors du surmoulage. Une fois que celle-ci est produite, la pièce métallique 10006 est mise en place et un le matériau plastique est injecté dans un moule, pour surmouler la pièce métallique et la paroi au travers des trous ou orifices de la pièce métallique, et former les pions 10016. As for the first exemplary embodiment, the overmoulding may be an insert molding, that is to say consisting of placing the metal part in a mold and injecting the plastic material around said part. As for the first embodiment, the metal part 1006 is disposed on the inner face of the wall 1004, that is to say the face defining the cavity formed by the housing and for receiving the lamp. The latter is inserted from the outside of the housing through the orifice 1008 so as to bear on the outer face of the wall 1004. The lamp fixing means, namely the pins protruding from the base (see discussion of Figure 2), cooperate with the metal part 1006, especially with the ramps 1014 of the housing, so as to exert a tensile force on the base of the lamp, maintaining it in stable support on the outer face of the wall 1002. The number and the arrangement of overmolding orifices may of course vary from the example just described. Indeed, a smaller number of orifices and possibly a different arrangement of the latter can be envisaged. Figure 6 illustrates a third embodiment of the invention. Unlike the previous examples, the wall 10004 supporting the metal part is no longer that of a housing but that of a lighting module 10002, intended to be placed in a lighting device, such as a projector. In the example illustrated in Figure 6, it is a reflector. As for the first and second exemplary embodiments, the overmoulding may be an insert molding, that is to say consisting of placing the metal part in a mold and injecting the plastic material around said part comprising the In addition, the metal part 10006 is no longer disposed directly against the wall 10004 but against the support elements 10005. These support elements 10005 project from the wall 10004 so that the metal part 10006 is at a distance. of the said wall 10004. The metal part 10006 serving as a support for the lamp 10020 is non-planar. It comprises a central portion of generally cylindrical shape and a generally flat portion with two "ears" resting on the support elements 10005. Each of the lateral portions forming lateral protrusions, legs or "ears", comprises one or more orifices intended to receive a pin or several pins 10016, respectively overmolded. In the specific case of Figure 7, each of the legs comprises a single overmolded pin. The support elements 10005 may comprise a hole of selected geometry, intended to receive the pin during overmolding. Once this is produced, the metal part 10006 is put in place and a plastic material is injected into a mold, overmolding the metal part and the wall through the holes or orifices of the metal part, and forming the 10016 counters.
La lampe 10020 est maintenue en place dans la partie cylindrique de la pièce métallique 10006 par une tige (non représentée) en forme de U et faisant ressort. Les extrémités de la tige se logent dans des articulations 10032 de la pièce métallique. Une boucle reliant ces extrémités se rabat sur la lampe et plaque son culot sur la pièce métallique. Elle se fixe en contrainte dans des crochets 10030, de sorte que par élasticité la tige maintien fermement la lampe. Dans le cas de l'exemple de la figure 6, la pièce métallique 10006 est visible depuis l'extérieur du module d'éclairage et la lampe vient en contact direct sur ladite pièce. Ce montage présente l'avantage de permettre une connexion électrique de la pièce métallique via un connecteur extérieur. Cette liaison électrique peut assurer l'alimentation électrique de la lampe via un connecteur de cette dernière (tel que par exemple son culot) en contact avec la pièce métallique 10006. La lampe 10020 peut ainsi ne comporter qu'un seul connecteur électrique. The lamp 10020 is held in place in the cylindrical portion of the metal part 10006 by a U-shaped, spring-loaded rod (not shown). The ends of the rod are housed in joints 10032 of the metal piece. A loop connecting these ends is folded on the lamp and plate its base on the metal piece. It is fixed in stress in hooks 10030, so that by elasticity the rod holds the lamp firmly. In the case of the example of Figure 6, the metal part 10006 is visible from outside the lighting module and the lamp comes into direct contact on said part. This arrangement has the advantage of allowing an electrical connection of the metal part via an external connector. This electrical connection can ensure the power supply of the lamp via a connector of the latter (such as for example its base) in contact with the metal part 10006. The lamp 10020 can thus have only one electrical connector.
La figure 7 illustre un quatrième exemple de réalisation de l'invention. Il constitue une variante de l'exemple de réalisation de la figure 6. En effet, la figure 7 diffère de la figure 6 en ce que les excroissances latérales de la pièce métallique 100006 formant des pattes et qui prennent appui sur les éléments supports 100005 sont surmoulées via les blocs de surmoulage 100016. Les pattes ne doivent pas nécessairement comporter de trou ou d'orifice étant donné le surmoulage d'au moins une partie de leur contour. Figure 7 illustrates a fourth embodiment of the invention. It constitutes a variant of the embodiment of FIG. 6. Indeed, FIG. 7 differs from FIG. 6 in that the lateral protuberances of the metal piece 100006 forming tabs and which bear on the support elements 100005 are overmoulded via the overmolding blocks 100016. The tabs do not necessarily have a hole or hole due to overmoulding at least part of their contour.
De manière générale, il est à remarquer que la pièce métallique servant de support à la lampe peut prendre diverses formes sans pour autant sortir du cadre de l'invention. Le type de lampe peut également varier. Il à été fait référence aux lampes du type H8 et H1 1 dans la description, étant entendu que l'invention peut être appliquée à d'autres types de lampe. La forme de la paroi du support ainsi formé avec la pièce métallique peut prendre diverses formes. Elle ne doit pas nécessairement être généralement plane, elle peut en effet être de forme gauche et complexe. Elle ne doit pas non plus nécessairement être une paroi de boîtier. En effet, elle peut être une paroi ou toute partie structurelle d'un module d'éclairage et/ou de signalisation. Il en va de même pour la pièce métallique recevant la lampe. En ce qui concerne le surmoulage, celui-ci peut prendre diverses formes. Il peut comprendre le surmoulage au travers d'un ou plusieurs orifices de la pièce métallique et/ou sur le bord de la dite pièce. In general, it should be noted that the metal part for supporting the lamp can take various forms without departing from the scope of the invention. The type of lamp can also vary. Reference has been made to lamps of the type H8 and H1 1 in the description, it being understood that the invention can be applied to other types of lamp. The shape of the wall of the support thus formed with the metal part can take various forms. It does not have to be generally flat, it can indeed be left-handed and complex. Nor does it necessarily have to be a case wall. Indeed, it may be a wall or any structural part of a lighting and / or signaling module. The same goes for the metal part receiving the lamp. With regard to overmolding, this can take various forms. It may include over-molding through one or more orifices of the metal part and / or on the edge of said part.
