Abstract

The outer (31) of two concentric skirts (31,32), behind the casing (30) centre, forms a receptacle for the mounting socket (50). Female connectors within the socket, crimped or soldered to the supply conductors (60), accept pins (53) on the lamp base (14), whose collar (12) locates it on the inner skirt (32). Socket passages are sealed with a self-hardening compound. After plugging and sealing the lamp into the socket, the bulb (11) is passed through the central openings (21). The socket enters the receptacle, to which it is sealed by a resilient ring (70), and secured by two clips (52). Finger-pads (521) on the latter allow them to be pinched inwards when withdrawal is necessary. The receptacle can be moulded on the reflector (20), supported by a sealing bellows on the casing (30).

Description

La présente invention a trait d'une façon générale aux connecteurs ou douilles pour lampes dans les projecteurs de véhicules automobiles.The present invention relates generally to connectors or sockets for lamps in motor vehicle headlamps.

De façon classique, une lampe de projecteur, telle qu'une lampe normalisée de type "H7", est montée dans un trou de lampe prévu au fond du réflecteur de telle manière qu'une collerette appartenant à ce type de lampe s'appuie contre une surface de référence par exemple annulaire entourant le trou de lampe.Conventionally, a projector lamp, such that a standard "H7" type lamp is mounted in a lamp hole provided at the bottom of the reflector such so that a flange belonging to this type of lamp leans against a reference surface for example ring surrounding the lamp hole.

Un dispositif de fixation du genre épingle élastique est alors manoeuvré pour verrouiller la lampe dans cette position, en maintenant l'appui précité.A pin-like fastening device elastic is then maneuvered to lock the lamp in this position, maintaining the aforementioned support.

Un connecteur relié au faisceau électrique du véhicule est alors appliqué à force sur l'arrière de la lampe pour assurer son alimentation par le biais de contacts mâle-femelle.A connector connected to the electrical harness of the vehicle is then forcibly applied to the rear of the lamp to ensure its supply through male-female contacts.

Lorsque le projecteur est du type à boítier, la mise en place et la connexion électrique de la lampe comme décrit ci-dessus s'effectuent de façon relativement incorfortable à l'intérieur du boítier, à travers une ouverture formée dans celui-ci, et doivent être suivies par une opération de mise en place sur le boítier d'un capuchon ou couvercle destiné à obturer l'ouverture de façon étanche.When the projector is of the case type, the fitting and electrical connection of the lamp as described above are done relatively uncomfortable inside the case, through a opening formed in it, and should be followed by a setting up operation on the housing of a cap or cover intended to close the opening of waterproof way.

On comprend que ces opérations, mises en oeuvre soit sur la chaíne de montage, soit en cas de remplacement d'une lampe défectueuse, sont longues et fastidieuses, et mettent en jeu de nombreuses pièces séparées, à savoir dispositif de fixation de lampe, connecteur et capuchon de boítier.We understand that these operations, implemented either on the assembly line, or in case of replacement of a defective lamp, are long and tedious, and involve many parts separate, namely lamp fixing device, connector and housing cap.

On connaít par le document US-A-5 088 011 décrit une capsule de lampe qui intègre, de façon fixe, la lampe elle-même. En particulier, les conducteurs d'alimentation de la lampe, qui est d'un type spécial, sont montés dans les pièces de connexion de la capsule d'une manière non démontable, notamment de par la présence d'un agent d'étanchéité, et c'est donc l'ensemble capsule/lampe qui doit être remplacé en cas de défaillance de la lampe.We know from the document US-A-5,088,011 described a lamp capsule which integrates the lamp in a fixed manner herself. In particular, the supply conductors of the lamp, which is of a special type, are mounted in the connecting parts of the capsule in a non removable, in particular by the presence of an agent seal, and therefore it is the capsule / lamp assembly which must be replaced if the lamp fails.

La présente invention vise à proposer un dispositif de support qui soit apte à coopérer avec une lampe à culot standard, tout en présentant des moyens d'étanchéité qui ne fassent nullement obstacle au montage de la lampe sur le dispositif ni à son démontage.The present invention aims to provide a device support which is able to cooperate with a lamp standard base, while presenting means that do not obstruct the assembly of the lamp on the device or when it is removed.

    • En référence tout d'abord à la figure 1, on a représenté schématiquement un projecteur de véhicule automobile, en l'espèce un projecteur antibrouillard, qui comprend principalement une lampe 10, un miroir 30, un boítier 30 et une glace non représentée.Referring first to Figure 1, we have schematically represented a vehicle headlamp automobile, in this case a fog light, which mainly includes a lamp 10, a mirror 30, a box 30 and a glass not shown.

    La lampe 10 est en l'espèce une lampe à filament normalisée de type "H7", dont la description complète figure dans les documents des normes officielles. Pour les besoins de la présente description, on notera simplement qu'elle comprend un bulbe 11, un culot 14, une collerette 12 s'étendant autour du culot, aindsiThe lamp 10 is in this case a filament lamp standard type "H7", full description appears in official standards documents. For the needs of this description, it will be noted simply that it includes a bulb 11, a base 14, a flange 12 extending around the base, aindsi

    En l'espèce, le miroir 20 est monté de façon réglable dans le boítier 30, afin d'ajuster la position du faisceau en site, tandis que la lampe 10 est montée fixe sur le boítier 30, de telle manière que son bulbe s'étende à travers une ouverture de fond 21 du miroir 20, convenablement surdimensionnée pour permettre le débattement du miroir par rapport à la lampe. In this case, the mirror 20 is mounted so adjustable in the housing 30, in order to adjust the position of the beam in elevation, while the lamp 10 is mounted fixed on the housing 30, so that its bulb extends through a bottom opening 21 of the mirror 20, suitably oversized to allow deflection of the mirror relative to the lamp.

    La lampe étant montée directement sur le boítier, il est prévu selon l'invention un dispositif 50 remplissant une triple fonction :

    • il constitue tout d'abord un dispositif de montage amovible de la lampe sur le boítier;
    • il constitue également un connecteur d'extrémité de faisceau permettant, lors de ce montage, de relier la lampe 10 au réseau de bord du véhicule;
    • enfin il constitue un dispositif de fermeture étanche de l'ouverture formée dans le boítier pour le passage de la lampe.
    The lamp being mounted directly on the housing, there is provided according to the invention a device 50 fulfilling a triple function:
    • it firstly constitutes a removable mounting device for the lamp on the housing;
    • it also constitutes a harness end connector making it possible, during this assembly, to connect the lamp 10 to the vehicle on-board network;
    • finally it constitutes a device for sealing the opening formed in the housing for the passage of the lamp.

    Ainsi la figure 1 montre schématiquement que le dispositif 50 possède un corps 51 à partir de la base duquel s'étendent deux bras flexibles 52 diamétralement opposés, pourvus chacun d'une partie saillante vers l'extérieur 521 à un niveau intermédiaire et d'une dent d'accrochage 522 à l'extrémité libre.Figure 1 schematically shows that the device 50 has a body 51 from the bottom from which extend two flexible arms 52 diametrically opposite, each provided with a projecting part towards outside 521 at an intermediate level and a tooth hooking 522 at the free end.

    Le boítier 30 possède quant à lui une ouverture postérieure entourée par une jupe intérieure 31 et par une jupe extérieure 32, ces jupes s'étendant vers l'arrière sur des distances axiales différentes.The housing 30 has an opening posterior surrounded by an inner skirt 31 and by an outer skirt 32, these skirts extending towards the rear over different axial distances.

    La jupe 32, plus courte, définit à son extrémité libre annulaire une surface d'appui pour la collerette 12 de la lampe 10.The shorter skirt 32 defines at its end free annular bearing surface for the collar 12 lamp 10.

    La jupe 31 possède dans la réfion de son extrémité libre des décrochements 311 adjacents à des ouvertures à travers lesquelles les dents d'accrochage 522 du dispositif 50 peuvent s'engager élastiquement pour verrouiller le dispositif et la lampe en place.The skirt 31 has in the refion of its end free of the recesses 311 adjacent to openings to through which the hooking teeth 522 of the device 50 can engage elastically to lock the device and the lamp in place.

    La connexion électrique entre la lampe 10 et les conducteurs 60 d'alimentation appartenant au faisceau électrique du véhicule est assurée par des organes de connexion logés dans des passages formés axialement dans le corps 51, le dispositif constituant ainsi un connecteur de terminaison de faisceau. Chaque organe de connexion comprend de préférence une partie de connexion femelle apte à recevoir un élément de connexion mâle correspondant 13 de la lampe, et une partie pour le sertissage ou le soudage de l'extrémité dénudée du conducteur correspondant 60.The electrical connection between the lamp 10 and the supply conductors 60 belonging to the bundle electric vehicle is provided by connection housed in axially formed passages in the body 51, the device thus constituting a harness termination connector. Each organ of connection preferably includes a connection part female capable of receiving a male connection element corresponding 13 of the lamp, and a part for the crimping or soldering the stripped end of the corresponding conductor 60.

    Enfin l'étanchéité entre le dispositif 50 et le boítier 30 est assurée par deux moyens :

    • d'une part, un joint torique 70 est reçu dans une gorge 55 formée à la périphérie du corps 51 et appliqué avec pression contre la face interne de la jupe 31 lors de la mise en place du dispositif 50;
    • d'autre part, un remplissage d'un matériau d'étanchéité électriquement isolant est réalisé dans les passages abritant les organes de connexion, ce matériau étant un matériau liquide ou visqueux durcissable classique en soi. Ce remplissage peut également contribuer à la bonne tenue mécanique des organes de connexion internes et des conducteurs 60.
    Finally, the seal between the device 50 and the housing 30 is ensured by two means:
    • on the one hand, an O-ring 70 is received in a groove 55 formed at the periphery of the body 51 and applied with pressure against the internal face of the skirt 31 when the device 50 is put in place;
    • on the other hand, an electrically insulating sealing material is filled in the passages housing the connection members, this material being a liquid or viscous curable material which is conventional in itself. This filling can also contribute to the good mechanical strength of the internal connection members and of the conductors 60.

    On réalise ainsi parfaitement l'étanchéité du boítier 30 au niveau de l'ouverture de mise en place du dispositif 50.This perfectly seals the box 30 at the opening for positioning the device 50.

    La figure 2 montre un autre type de projecteur équipé d'un dispositif de montage, de connexion et d'étanchéité selon l'invention.Figure 2 shows another type of projector fitted with a mounting, connection and sealing according to the invention.

    Dans cet exemple, la lampe 10 est montée, à l'aide du même dispositif 50, non plus sur le boítier 30 du projecteur, mais sur le réflecteur 20, de façon classique en soi. In this example, the lamp 10 is mounted, using of the same device 50, no longer on the housing 30 of the projector, but on the reflector 20, conventionally in itself.

    Pour rendre la partie de fond du réflecteur 20 accessible de l'extérieur, le boítier 30 est muni d'une ouverture 33 dont les dimensions sont supérieures aux dimensions tranversales du dispositif 50 équipé de sa lampe 10. En outre, afin de garantir l'étanchéité de l'espace intérieur du boítier par rapport aux agents extérieurs, on prévoit un élément déformable d'étanchéité opérant entre le boítier autour de son ouverture 33 et le réflecteur 20 autour du-dispositif 50.To make the bottom part of the reflector 20 accessible from the outside, the housing 30 is provided with a opening 33 whose dimensions are greater than transverse dimensions of the device 50 equipped with its lamp 10. In addition, in order to guarantee the watertightness of the interior space of the case in relation to the agents exterior, a deformable sealing element is provided operating between the housing around its opening 33 and the reflector 20 around the device 50.

    Plus précisément, cet élément d'étanchéité consiste en un soufflet 40 en forme de couronne, réalisé par exemple en matériau élastomètre, dont un bord extérieur possède une pince continue 41 destiné à relier le soufflet 40 de façon étanche à un rebord 34 du boítier entourant l'ouverture 33, et dont un bord intérieur possède une autre pince continue 42 destinée à effectuer la liaison étanche du soufflet avec l'extrémité libre d'une jupe 23 prévue sur le réflecteur, en saillie vers l'arrière, autour et à distance de la jupe 21 qui circonscrit le dispositif 50.More specifically, this sealing element consists in a bellows 40 in the shape of a crown, produced by example in elastometer material, including an outer edge has a continuous clamp 41 intended to connect the bellows 40 sealingly to a rim 34 of the housing surrounding the opening 33, and including an inner edge has another continuous clamp 42 intended to perform the tight connection of the bellows with the free end a skirt 23 provided on the reflector, projecting towards the rear, around and at a distance from the skirt 21 which circumscribes the device 50.

    On observera ici que la déformabilité de ce soufflet 40 permet d'accepter les variations de position entre le boítier 30 et le réflecteur 20 lorsque ce dernier est déplacé à des fins de réglage de faisceau.It will be observed here that the deformability of this bellows 40 allows position variations to be accepted between the housing 30 and the reflector 20 when this the latter is moved for beam setting purposes.

    Dans les deux exemples ci-dessus, l'assemblage s'effectue en montant tout d'abord la lampe sur le dispositif 50, avant que ce dernier ne soit mis en place. Ensuite, le dispositif 50 portant la lampe 10 est mis en place unitairement dans l'ouverture arrière du boítier 30, de telle manière que le bulbe 11 de la lampe vienne occuper la position souhaitée dans le réflecteur 20. La connexion de la lampe s'effectue donc préalablement, suivie du montage proprement-dit avec fonction d'étanchéité.In the two examples above, the assembly is carried out by first mounting the lamp on the device 50, before the latter is put in place. Then, the device 50 carrying the lamp 10 is put in unitary place in the rear opening of the case 30, so that the bulb 11 of the lamp comes occupy the desired position in the reflector 20. The the lamp is therefore connected beforehand, followed by the actual assembly with function sealing.

    Ces opérations sont sensiblement plus simples que dans l'état de la technique antérieure.These operations are significantly simpler than in the state of the prior art.

    On va maintenant décrire plus en détail, en référence aux figures 3 à 8, la structure du dispositif 50.We will now describe in more detail, in reference to FIGS. 3 to 8, the structure of the device 50.

    Celui-ci est constitué principalement par une pièce moulée en matière plastique comportant un corps généralement cylindrique 51.This consists mainly of a part molded plastic material having a body generally cylindrical 51.

    A partir de ce corps s'étendent de façon diamétralement opposée, le long dudit corps, les deux bras de verrouillage 52 munis de leurs zones de pression 521 et de leurs dents d'ancrage 522. Les zones de pression 521 sont avantageusement munies de stries permettant aux doigts de l'opérateur d'exercer convenablement les efforts de mise en place et de retrait du dispositif selon la direction axiale.From this body extend so diametrically opposite, along said body, the two locking arm 52 provided with their pressure zones 521 and their anchor teeth 522. The areas of pressure 521 are advantageously provided with ridges allowing the operator's fingers to exercise proper efforts to set up and remove of the device in the axial direction.

    En des positions décalées angulairement de 90_ par rapport à ces bras 52 sont prévues sur le corps 51 deux zones striées 53 permettant également d'exercer sur le dispositif les efforts axiaux précités.In positions offset angularly by 90_ by relative to these arms 52 are provided on the body 51 two striated zones 53 also allowing exercise on the device the aforementioned axial forces.

    A travers le corps 51 s'étendent, de façon généralement axiale et parallèlement l'un à l'autre, deux passages axiaux 541 de section généralement rectangulaire qui débouchent, au niveau de la face arrière du dispositif (face opposée à la lampe 10), sur deux orifices circulaires 54 d'entrée pour deux conducteurs 60 d'alimentation de la lampe.Through the body 51 extend, so generally axial and parallel to each other, two axial passages 541 of generally rectangular section which open out, at the rear side of the device (opposite the lamp 10), out of two circular inlet ports 54 for two conductors 60 lamp power supply.

    Dans ces passages 541 sont logés et retenus en place respectivement les deux organes de connexion (non représentés,) qui possèdent chacun une partie formant connecteur femelle pour un contact 13 de la lampe, et une partie destinée à sertir l'extrémité dénudée d'un conducteur associé 60. Bien entendu, on prévoit de retenir les organes de connexion en place par tout dispositif d'accrochage, d'encastrement, ... approprié.In these passages 541 are housed and retained in places the two connecting members respectively (not represented,) which each have a part forming female connector for a lamp contact 13, and a part intended to crimp the stripped end of a associated conductor 60. Of course, provision is made for hold the connecting members in place by all hooking, embedding device, ... suitable.

    Ces organes de connexion sont bien connus dans le domaine des connecteurs électriques, notamment dans le domaine automobile, et ne seront pas décrits en détail.These connecting members are well known in the art. electrical connectors, particularly in the automotive field, and will not be described in detail.

    On observe en particulier sur les figures 3, 7 et 8 la gorge circulaire 55 formée à la périphérie du corps 51 pour recevoir le joint torique 70 représenté sur les figures 1 et 2.We observe in particular in Figures 3, 7 and 8 the circular groove 55 formed at the periphery of the body 51 to receive the O-ring 70 shown on the Figures 1 and 2.

    Sur sa face antérieure, tournée vers la lampe, le corps 51 du dispositif 50 comporte une pluralité d'aménagements destinés essentiellement à recevoir et à caler le culot 14 de la lampe normalisée "H7" et à fixer ce culot de façon fiable au dispositif 50.On its front side, facing the lamp, the body 51 of device 50 comprises a plurality arrangements intended primarily to receive and wedge the base 14 of the standard lamp "H7" and fix this base reliably to the device 50.

    Ainsi on a illustré deux ergots diamétralement opposés 56 destinés à coopérer par complémentarité de formes avec deux encoches complémentaires appartenant au culot de la lampe, pour assurer un détrompage lors de l'enfichage de la lampe.Thus we have illustrated two diametrically lugs opposites 56 intended to cooperate by complementarity of shapes with two complementary notches belonging to the lamp base, to ensure polarization during inserting the lamp.

    On a également représenté deux parties en saillie 57 disposées de façon diamétralement opposée et possédant deux faces en vis-à-vis, à partir desquelles s'étendent deux ergots de retenue 571. Ces ergots sont destinés à retenir, en coopération avec d'autres aménagements en saillie 58, un fil-ressort plié, ou épingle, destiné à verrouiller le culot 14 de la lampe 10 sur le dispositif, d'une manière parfaitement connue en soi. Ce type d'épingle est notamment utilisé dans l'art antérieur pour retenir le culot d'une lampe sur le miroir.There are also two protruding parts 57 arranged diametrically opposite and having two opposite faces, from which extend two retaining pins 571. These pins are intended for retain, in cooperation with other developments in projection 58, a folded spring wire, or pin, intended for lock the base 14 of the lamp 10 on the device, in a manner perfectly known per se. This guy is particularly used in the prior art for retain the base of a lamp on the mirror.

    On observera ici qu'une telle épingle permet, en sollicitant la lampe 10 élastiquement vers le dispositif 50, de donner à ladite lampe une position bien déterminée par rapport audit dispositif. De la sorte, la mise en place du dispositif sur l'arrière du boítier 30 ou du réflecteur 20, qui s'effectue selon un positionnement précis par l'accrochage élastique réalisé, permet de bien positionner la lampe par rapport au réflecteur.It will be observed here that such a pin allows, in urging the lamp 10 elastically towards the device 50, to give said lamp a well-defined position with respect to said device. In this way, the implementation place of the device on the rear of the housing 30 or of the reflector 20, which takes place according to a positioning precise by the elastic hooking achieved, allows good position the lamp in relation to the reflector.

    Enfin, afin de compléter l'étanchéité réalisée par le joint torique 70, on prévoit d'équiper le dispositif 50, une fois que les organes de connexion, préalablement sertis sur les conducteurs 60, ont été mis en place dans leurs passages 541, d'un matériau électriquement isolant qui est introduit dans les passages 541 et dans les orifices 54 à l'état liquie ou visqueux, puis durci. Cette introduction peut se faire via les orifices 54 et/ou via des orifices latéraux diamétralement opposés 59 débouchant dans les passages 541.Finally, in order to complete the watertightness achieved by the O-ring 70, provision is made to equip the device 50, once the connecting members, previously crimped on the conductors 60, have been put in place their passages 541, of an electrically insulating material which is introduced in passages 541 and in orifices 54 in a liquid or viscous state, then hardened. This introduction can be done via the openings 54 and / or via diametrically opposite lateral orifices 59 opening into passages 541.

    On notera ici qu'un tel remplissage en matériau durcissable permet avantageusement de renforcer la retenue des organes de connexion et des conducteurs 60 par rapport au corps 51 du dispositif 50.It will be noted here that such a filling of material curable advantageously strengthens the retaining connection members and conductors 60 relative to the body 51 of the device 50.

    Bien entendu, la présente invention n'est nullement limitée à la forme de réalisation décrite ci-dessus et représentée sur les dessins, mais l'homme du métier saura y apporter toute variante ou modification conforme à son esprit.Of course, the present invention is by no means limited to the embodiment described above and shown in the drawings, but the skilled person will know make any variant or modification in accordance with its mind.

    En particulier, l'homme du métier saura faire les adaptations nécessaires pour utiliser le dispositif de montage, de connexion et d'étanchéité selon l'invention avec d'autres types de lampes, normalisées ou non.In particular, the person skilled in the art will be able to make the adaptations necessary to use the device mounting, connection and sealing according to the invention with other types of lamps, standardized or not.
