Description

La présente invention concerne une douille ou un porte-lampe ou un support d'une ampoule d'un module optique d'un dispositif d'éclairage et/ou de signalisation d'un véhicule automobile.The present invention relates to a socket or a lamp holder or a support of a light bulb of an optical module of a lighting and / or signaling device of a motor vehicle.

Un support d'ampoule ou un porte-lampe ou douille assure plusieurs fonctions. Une première fonction est de maintenir mécaniquement l'ampoule dans une position déterminée. Ce maintien en position peu en particulier être obtenu grâce à des moyens mécaniques du support d'ampoule coopérant avec des moyens mécaniques d'un culot de l'ampoule. Ces moyens mécaniques peuvent notamment consister en des conformations particulières du support d'ampoule et du culot de l'ampoule. Une deuxième fonction est d'alimenter électriquement l'ampoule. Pour ce faire, le support d'ampoule comprend des moyens électriques, notamment des contacts électriques, destinés à coopérer avec des moyens électriques, notamment des contacts électriques, prévus sur l'ampoule, notamment prévus sur le culot de l'ampoule.A bulb holder or lamp holder or socket provides several functions. A first function is to mechanically maintain the bulb in a specific position. This holding in position can in particular be obtained thanks to mechanical means of the bulb holder cooperating with mechanical means of a base of the bulb. These mechanical means may in particular consist of particular conformations of the bulb holder and the base of the bulb. A second function is to power the bulb. To do this, the bulb holder comprises electrical means, including electrical contacts, intended to cooperate with electrical means, including electrical contacts, provided on the bulb, in particular provided on the base of the bulb.

Dans certains cas, certains des moyens mécaniques et des moyens électriques évoqués précédemment peuvent être confondus pour assurer simultanément tout ou partie de la fonction de maintien mécanique de l'ampoule et tout ou partie de la fonction électrique de connexion de l'ampoule, comme décrit dans EP 1 666 789 .In some cases, some of the mechanical means and electrical means mentioned above may be combined to simultaneously provide all or part of the mechanical holding function of the bulb and all or part of the electrical connection function of the bulb, as described in EP 1 666 789 .

Dans le domaine de l'éclairage et de la signalisation des véhicules automobiles, de nouvelles réglementations imposent que pour certains types de dispositifs d'éclairage et/ou de signalisation, les ampoules ne puissent pas être démontées de la douille ou, tout au moins, qu'après démontage de l'ampoule, la douille ou le porte-lampe ou le support d'une ampoule ne puisse plus être utilisé pour recevoir une nouvelle ampoule. Dans ces cas, c'est l'ensemble du module optique, incluant l'ampoule et la douille, qui doit être remplacé.In the field of lighting and signaling of motor vehicles, new regulations require that for certain types of lighting and / or signaling devices, the bulbs can not be removed from the socket or, at least, after dismantling the bulb, socket, lamp holder or holder of a bulb can no longer be used to receive a new bulb. In these cases, the entire optical module, including the bulb and socket, must be replaced.

Il apparaît par conséquent nécessaire de développer des solutions permettant un montage aisé et rapide d'une ampoule sur une douille lors d'opérations de production de module optique et interdisant le démontage de l'ampoule ou endommageant la douille lors du démontage de l'ampoule de sorte que cette douille ne puisse plus être utilisée après démontage de l'ampoule.It therefore appears necessary to develop solutions allowing a quick and easy mounting of a bulb on a socket during optical module production operations and prohibiting disassembly of the bulb or damaging the socket during disassembly of the bulb so that this socket can not be used after disassembly of the bulb.

Les douilles connues sont justement conçues de sorte à permettre un échange simple, rapide et aisé d'une ampoule.The known sockets are precisely designed to allow a simple exchange, quick and easy bulb.

Le but de l'invention est de fournir un support d'ampoule permettant de remédier aux inconvénients évoqués ci-dessus et améliorant les supports d'ampoule connus de l'art antérieur. En particulier, l'invention propose un support d'ampoule permettant un montage aisé, rapide et simple d'une ampoule sur le support lors d'opérations de production de modules optiques et interdisant le démontage de l'ampoule ou endommageant le support d'ampoule lors du démontage de l'ampoule de sorte que ce support d'ampoule ne puisse plus être utilisé après démontage de l'ampoule.The object of the invention is to provide a bulb holder to overcome the disadvantages mentioned above and improving bulb holders known from the prior art. In particular, the invention proposes a bulb holder allowing an easy, fast and simple mounting of a bulb on the support during operations of production of optical modules and prohibiting the disassembly of the bulb or damaging the support of bulb when disassembling the bulb so that bulb holder can no longer be used after disassembly of the bulb.

Le document WO 2009/014574 décrit un connecteur à témoin de démontage qui peut éventuellement être utilisé dans un environnement sécurisé de calcul, pour fournir la preuve d'un démontage non autorisé d'un circuit intégré sur une carte de circuit.The document WO 2009/014574 discloses a disassembly indicator connector which may optionally be used in a secure computing environment to provide evidence of unauthorized disassembly of an integrated circuit on a circuit board.

Selon l'invention, le support d'une ampoule d'un module optique d'un dispositif d'éclairage et/ou de signalisation d'un véhicule automobile, comprend un moyen de connexion électrique de l'ampoule. Le support comprend un moyen d'altération du moyen de connexion électrique de l'ampoule, le moyen d'altération agissant lors du retrait de l'ampoule dudit support. Ainsi, toute dépose ou retrait de l'ampoule provoque une modification, de préférence une détérioration, du support empêchant le montage ultérieur d'une nouvelle ampoule sur le support.According to the invention, the support of a light bulb of an optical module of a lighting and / or signaling device of a motor vehicle, comprises a means of electrical connection of the bulb. The support comprises a means for altering the electrical connection means of the bulb, the tamper means acting during removal of the bulb from said support. Thus, any removal or removal of the bulb causes a modification, of preferably a deterioration, the support preventing the subsequent mounting of a new bulb on the support.

Le moyen d'altération peut comprendre une première conformation prévue sur un premier élément du support coopérant par obstacle avec une deuxième conformation prévue sur un culot de l'ampoule. Ces moyens simples permettent de réaliser un moyen d'altération efficace.The alteration means may comprise a first conformation provided on a first element of the support cooperating by obstacle with a second conformation provided on a base of the bulb. These simple means make it possible to produce an effective means of alteration.

La deuxième conformation peut comprendre un épaulement.The second conformation may include a shoulder.

Le premier élément peut comprendre un renfort du moyen de connexion électrique, notamment un renfort d'une lame de connexion électrique. Ainsi, le renfort étant altéré, la connexion électrique n'est plus garantie.The first element may comprise a reinforcement of the electrical connection means, in particular a reinforcement of an electrical connection blade. Thus, the reinforcement being altered, the electrical connection is no longer guaranteed.

La première conformation peut comprendre un épaulement. Il s'agit d'une conformation simple à réaliser et efficace.The first conformation may include a shoulder. It is a conformation simple to realize and effective.

Le premier élément peut comprendre le moyen de connexion électrique, notamment une lame de connexion électrique.The first element may comprise the electrical connection means, in particular an electrical connection blade.

Le moyen d'altération peut provoquer, lors de son action, une rupture d'au moins un élément du moyen de connexion électrique, notamment une rupture d'une lame de connexion électrique ou une rupture d'un renfort du moyen de connexion électrique.The alteration means may cause, during its action, a break of at least one element of the electrical connection means, in particular a break of an electrical connection blade or a breakage of a reinforcement of the electrical connection means.

Le moyen d'altération peut provoquer, lors de son action, une déformation plastique d'au moins un élément du moyen de connexion électrique, notamment une déformation plastique d'une lame de connexion électrique.The alteration means may cause, during its action, a plastic deformation of at least one element of the electrical connection means, in particular a plastic deformation of an electrical connection blade.

Le moyen d'altération peut provoquer, lors de son action, un arrachement d'au moins un élément du moyen de connexion électrique, notamment un arrachement d'une lame de connexion électrique.The tampering means may cause, during its action, tearing of at least one element of the electrical connection means, including tearing of an electrical connection blade.

De préférence, le moyen d'altération provoque, lors de son action, un arrachement de matière d'une pièce maintenant mécaniquement l'au moins un élément du moyen de connexion électrique.Preferably, the alteration means causes, during its action, tearing material of a part now mechanically the at least one element of the electrical connection means.

De préférence, le moyen d'altération ne provoque pas d'altération du moyen de connexion électrique de l'ampoule lors de l'introduction de l'ampoule dans le support et/ou le moyen d'altération provoque une déformation élastique d'un élément du moyen de connexion électrique de l'ampoule lors de l'introduction de l'ampoule dans le support.Preferably, the alteration means does not cause alteration of the electrical connection means of the bulb during the introduction of the bulb into the support and / or the alteration means causes an elastic deformation of a element of the electrical connection means of the bulb during the introduction of the bulb into the support.

Notamment, le support d'ampoule selon l'invention peut être un support d'ampoule d'un module optique d'un dispositif d'éclairage et/ou de signalisation d'un véhicule automobile. Le support d'ampoule peut aussi être destiné à recevoir un ampoule utilisée dans toute autre application.The bulb holder according to the invention can be a bulb holder of an optical module of a lighting and / or signaling device. In particular, the bulb holder according to the invention may be a bulb holder of an optical module of a lighting and / or signaling device of a motor vehicle. The bulb holder can also be used to receive a bulb used in any other application.

Un premier mode de réalisation du support 100 d'ampoule selon l'invention est décrit ci-après en référence aux figures 1 à 6.A first embodiment of the bulb holder 100 according to the invention is described below with reference to Figures 1 to 6 .

Le support 100 comprend principalement une embase 101 et un fût 102. L'embase est destinée à fixer le support à une structure, notamment une structure d'un dispositif d'éclairage et/ou de signalisation. À cet effet, l'embase peut comprendre des moyens de fixation et/ou des moyens de positionnement.The support 100 mainly comprises a base 101 and a shaft 102. The base is intended to fix the support to a structure, including a structure of a lighting and / or signaling device. For this purpose, the base may comprise fixing means and / or positioning means.

Le fût comprend de préférence un moyen 104, 103 de fixation ou de maintien mécanique d'une ampoule 10 sur le support et un moyen 105, 106 de connexion électrique de l'ampoule. L'ampoule comprend par exemple un bulbe en verre 11 et un culot 12.The barrel preferably comprises a means 104, 103 for fixing or mechanical retention of a bulb 10 on the support and a means 105, 106 of electrical connection of the bulb. The bulb comprises for example a glass bulb 11 and a base 12.

Le moyen de fixation ou de maintien mécanique de l'ampoule permet de positionner l'ampoule relativement au support et de maintenir celle-ci dans cette position. Par exemple, le moyen de fixation mécanique comprend des clips 104 en forme de crochets présentant des épaulements 120 et destinés à coopérer avec une forme prévue sur l'ampoule, notamment un épaulement 13 prévu sur l'ampoule, en particulier prévu sur le culot 12 de l'ampoule. Ainsi, lors de l'introduction ou du montage de l'ampoule dans le support, les clips sont déformés élastiquement jusqu'à ce que l'épaulement 13 vienne en arrière des épaulements 120. Une fois dans cette position, les clips sont rappelés élastiquement dans leur position d'origine dans laquelle les épaulements 13 et 120 coopèrent pour empêcher la dépose ou le retrait de l'ampoule. Le moyen de fixation ou de maintien mécanique peut aussi comprendre un détrompeur comme une nervure 107 destinée à coopérer avec une rainure prévue sur le culot de l'ampoule.The means for fixing or holding the ampoule mechanically makes it possible to position the bulb relative to the support and to hold the latter in this position. For example, the mechanical fixing means comprises clips 104 in the form of hooks having shoulders 120 and intended to cooperate with a shape provided on the bulb, in particular a shoulder 13 provided on the bulb, in particular provided on the base 12 of the bulb. Thus, during the introduction or assembly of the bulb in the support, the clips are deformed elastically until the shoulder 13 comes back from the shoulders 120. Once in this position, the clips are elastically recalled in their original position in which the shoulders 13 and 120 cooperate to prevent the removal or removal of the bulb. The fixing or mechanical holding means may also comprise a polarizer such as a rib 107 intended to cooperate with a groove provided on the base of the bulb.

Le moyen 105, 106 de connexion électrique de l'ampoule comprend au moins deux contacts électriques 106 destinés à coopérer avec au moins deux contacts électriques prévus sur l'ampoule, notamment sur le culot 12 de l'ampoule. De préférence, les contacts électriques du moyen de connexion électrique comprennent des lames 106, par exemple des lames métalliques, destinées à être reliées électriquement à une source d'énergie électrique permettant d'activer l'ampoule. Le moyen de connexion électrique peut comprendre des supports ou renforts 105 maintenant les lames. De préférence, ces renforts 105 sont réalisés dans la même matière et venus d'une même pièce avec le fût. Ils permettent de rigidifier et/ou de maintenir les lames électriques. Par exemple, les renforts sont réalisés en matière plastique.The means 105, 106 of electrical connection of the bulb comprises at least two electrical contacts 106 intended to cooperate with at least two electrical contacts provided on the bulb, in particular on the base 12 of the bulb. Preferably, the electrical contacts of the electrical connection means comprise blades 106, for example metal blades, intended to be electrically connected to a source of electrical energy for activating the bulb. The electrical connection means may comprise supports or reinforcements 105 holding the blades. Preferably, these reinforcements 105 are made of the same material and come from the same piece with the barrel. They make it possible to stiffen and / or maintain the electric blades. For example, the reinforcements are made of plastic.

Le support 100 comprend aussi un moyen 110, 112 d'altération du moyen de connexion électrique de l'ampoule. Le moyen d'altération comprend par exemple principalement des épaulements 112 prévus sur les renforts 105 et des sections 110 de moindre résistance mécanique des renforts, notamment des sections de moindre résistance mécanique des renforts à leurs bases ou aux voisinages de celles-ci. Le moyen d'altération est destiné à coopérer avec une forme prévue sur l'ampoule, notamment des épaulements 16 prévus sur l'ampoule, en particulier prévu sur le culot 12 de l'ampoule. Ainsi, lors de l'introduction ou du montage de l'ampoule dans le support, les renforts et les lames sont déformés élastiquement jusqu'à ce que les épaulements 16 viennent en arrière des épaulements 112. Une fois dans cette position, les renforts sont rappelés élastiquement dans leur position d'origine dans laquelle les épaulements 16 et 112 coopèrent pour empêcher la dépose ou le retrait de l'ampoule. Néanmoins, si on force sur l'ampoule pour la déposer ou la retirer comme représenté aux figures 3, 5 et 6, les épaulements 16 du culot de l'ampoule exercent, par obstacle, une action mécanique sur les épaulements 112 des renforts 105. Il s'ensuit des contraintes mécaniques provoquant la rupture des sections 110 de moindre résistance mécanique des renforts. De plus, les épaulements 16 du culot de l'ampoule exercent une action mécanique sur les épaulements 112 des renforts 105 qui provoque un arrachement des lames 106 comme représenté à la figure 6. En effet, les lames sont de préférence insérées en force dans des rainures du fût dans lesquelles elles sont maintenues par l'action d'une ou plusieurs lamelles élastiques 180. De préférence, lors de l'arrachement des lames, les lamelles élastiques 180 détériorent localement les rainures, par exemple en arrachant de la matière. En effet, les lamelles peuvent pas leur conformation formée un copeau dans la matière constituant les rainuresThe support 100 also comprises means 110, 112 for altering the electrical connection means of the bulb. The alteration means comprises for example mainly shoulders 112 provided on the reinforcements 105 and sections 110 of lesser mechanical strength reinforcements, including sections of least strength reinforcements at their bases or neighborhoods thereof. The alteration means is intended to cooperate with a shape provided on the bulb, including shoulders 16 provided on the bulb, in particular provided on the base 12 of the bulb. Thus, during the introduction or assembly of the bulb in the support, the reinforcements and the blades are deformed elastically until the shoulders 16 come back from the shoulders 112. Once in this position, the reinforcements are resiliently returned to their original position in which the shoulders 16 and 112 cooperate to prevent the removal or removal of the bulb. Nevertheless, if you force on the bulb to remove it or remove it as shown in figures 3 , 5 and 6 , the shoulders 16 of the base of the bulb exert, by obstacle, a mechanical action on the shoulders 112 of the reinforcements 105. It follows mechanical stresses causing the rupture of the sections 110 of lower strength of the reinforcements. In addition, the shoulders 16 of the base of the bulb exert a mechanical action on the shoulders 112 reinforcements 105 which causes tearing of the blades 106 as shown in FIG. figure 6 . Indeed, the blades are preferably inserted in force in the grooves of the barrel in which they are held by the action of one or more elastic lamellae 180. Preferably, during the tearing of the blades, the elastic lamellae 180 deteriorate. locally the grooves, for example tearing material. Indeed, the slats can not conform to their shape formed a chip in the material constituting the grooves

Ainsi, une fois l'ampoule déposée, des renforts du moyen de connexion électrique sont rompus, des contacts électriques du moyen de connexion électrique sont arrachés et des rainures, destinées à recevoir et à immobiliser ces contacts électriques, sont détériorées. En conséquence, le moyen d'altération est activé lors de la dépose ou du retrait de l'ampoule et il altère, au cours de cette opération, le moyen de connexion électrique. Si on tente de réinsérer les lames dans le fût du support, leur maintien mécanique dans celui-ci n'est plus suffisant du fait de la détérioration des rainures et leur rigidité n'est plus suffisante du fait de la rupture des renforts. Ainsi, la connexion électrique de l'ampoule dans le support n'est plus garantie, voire plus possible.Thus, once the bulb deposited, reinforcements of the electrical connection means are broken, electrical contacts of the electrical connection means are torn off and grooves for receiving and immobilizing these electrical contacts are damaged. Consequently, the tampering means is activated during the removal or removal of the bulb and it alters, during this operation, the electrical connection means. If one attempts to reinsert the blades in the support shaft, their mechanical retention therein is no longer sufficient because of the deterioration of the grooves and their rigidity is no longer sufficient due to the rupture of the reinforcements. Thus, the electrical connection of the bulb in the holder is no longer guaranteed or even possible.

Il est clair que, dans une variante, le moyen d'altération peut uniquement provoquer la rupture des renforts sans provoquer l'arrachement des lames. Dans une autre variante, une lame peut présenter des sections de moindre résistance mécanique et une rupture peut se produire à ce niveau lors de la dépose ou du retrait de l'ampoule.It is clear that, in one variant, the alteration means can only cause the reinforcements to break without causing the blades to tear. In another variant, a blade may have sections of lower mechanical strength and a break may occur at this level during the removal or removal of the bulb.

Un deuxième mode de réalisation du support 200 d'ampoule selon l'invention est décrit ci-après en référence aux figures 7a, 7b et 8 à 12.A second embodiment of the bulb holder 200 according to the invention is described below with reference to the Figures 7a, 7b and 8 to 12 .

Le support 200 comprend principalement une embase 201 et un fût 202 présentant les mêmes fonctions que celles décrites en relation avec le premier mode de réalisation.The support 200 mainly comprises a base 201 and a shaft 202 having the same functions as those described in relation to the first embodiment.

Le fût comprend de préférence un moyen 204, 203 de fixation ou de maintien mécanique de l'ampoule 10 sur le support et un moyen 206 de connexion électrique de l'ampoule.The barrel preferably comprises a means 204, 203 for fixing or mechanical support of the bulb 10 on the support and means 206 for electrical connection of the bulb.

Le moyen de fixation ou de maintien mécanique de l'ampoule permet de positionner l'ampoule relativement au support et de maintenir celle-ci dans cette position. Par exemple, le moyen de fixation mécanique comprend des clips 204 en forme de crochets présentant des épaulements 220 et destinés à coopérer avec une forme prévue sur l'ampoule, notamment un épaulement 13 prévu sur l'ampoule, en particulier prévu sur le culot 12 de l'ampoule. Ainsi, lors de l'introduction ou du montage de l'ampoule dans le support, les clips sont déformés élastiquement jusqu'à ce que l'épaulement 13 vienne en arrière des épaulements 220. Une fois dans cette position, les clips sont rappelés élastiquement dans leur position d'origine dans laquelle les épaulements 13 et 220 coopèrent pour empêcher la dépose ou le retrait de l'ampoule. Le moyen de fixation ou de maintien mécanique peut aussi comprendre un détrompeur comme une nervure destinée à coopérer avec une rainure prévue sur le culot de l'ampoule.The means for fixing or holding the ampoule mechanically makes it possible to position the bulb relative to the support and to hold the latter in this position. For example, the mechanical fixing means comprises clips 204 in the form of hooks having shoulders 220 and intended to cooperate with a shape provided on the bulb, in particular a shoulder 13 provided on the bulb, in particular provided on the base 12 of the bulb. Thus, when inserting or mounting the bulb in the holder, the The clips are elastically deformed until the shoulder 13 comes back from the shoulders 220. Once in this position, the clips are resiliently returned to their original position in which the shoulders 13 and 220 cooperate to prevent removal or the removal of the bulb. The fixing or mechanical holding means may also comprise a polarizer such as a rib intended to cooperate with a groove provided on the base of the bulb.

Le moyen 206 de connexion électrique de l'ampoule comprend au moins deux contacts électriques 206 destinés à coopérer avec au moins deux contacts électriques prévus sur l'ampoule, notamment sur le culot 12 de l'ampoule. De préférence, les contacts électriques du moyen de connexion électrique comprennent des lames 206, par exemple des lames métalliques, destinées à être reliées électriquement à une source d'énergie électrique permettant d'activer l'ampoule. De préférence, les lames comprennent au moins une pliure 213 et une portion repliée 219 terminée par une extrémité 212.The means 206 for the electrical connection of the bulb comprises at least two electrical contacts 206 intended to cooperate with at least two electrical contacts provided on the bulb, in particular on the base 12 of the bulb. Preferably, the electrical contacts of the electrical connection means comprise blades 206, for example metal blades, intended to be electrically connected to a source of electrical energy for activating the bulb. Preferably, the blades comprise at least one fold 213 and a folded portion 219 terminated by an end 212.

Le support 200 comprend aussi un moyen 212 d'altération du moyen de connexion électrique de l'ampoule. Le moyen d'altération comprend par exemple principalement les extrémités 212 évoquées précédemment. Le moyen d'altération est destiné à coopérer avec une forme prévue sur l'ampoule, notamment des épaulements 16 prévus sur l'ampoule, en particulier prévu sur le culot 12 de l'ampoule. Ainsi, lors de l'introduction ou du montage de l'ampoule dans le support, les lames sont déformées élastiquement jusqu'à ce que les épaulements 16 viennent en arrière des extrémités 212 des lames. Une fois dans cette position, les lames sont rappelées élastiquement vers leurs positions d'origines. Ainsi, les épaulements 16 et les extrémités 212 coopèrent pour empêcher la dépose ou le retrait de l'ampoule et les lames sont en appui contre les contacts électriques prévus sur l'ampoule. Néanmoins, si on force sur l'ampoule pour la déposer comme représenté aux figures 9 à 12, les épaulements 16 du culot de l'ampoule exercent, par obstacle, une action mécanique sur les extrémités 212 et provoquent une déformation des lames, notamment une déformation plastique c'est-à-dire une déformation allant au-delà du domaine de déformation élastique dans lequel après une déformation la lame revient à son état initial.The support 200 also comprises a means 212 for altering the electrical connection means of the bulb. The alteration means comprises for example mainly the ends 212 mentioned above. The alteration means is intended to cooperate with a shape provided on the bulb, including shoulders 16 provided on the bulb, in particular provided on the base 12 of the bulb. Thus, during the introduction or assembly of the bulb in the support, the blades are deformed elastically until the shoulders 16 come behind the ends 212 of the blades. Once in this position, the blades are resiliently returned to their original positions. Thus, the shoulders 16 and the ends 212 cooperate to prevent the removal or removal of the bulb and the blades are pressed against the electrical contacts provided on the bulb. Nevertheless, if we force on the bulb to deposit it as represented to Figures 9 to 12 , the shoulders 16 of the base of the bulb exert, by obstacle, a mechanical action on the ends 212 and cause a deformation of the blades, in particular a plastic deformation that is to say a deformation beyond the deformation range elastic in which after deformation the blade returns to its initial state.

Ainsi, une fois l'ampoule déposée, les lames 206 demeurent dans un état déformé représenté à la figure 12. En conséquence, le moyen d'altération est activé lors de la dépose ou du retrait de l'ampoule et il altère au cours de cette opération le moyen de connexion électrique. Si on tente de réinsérer l'ampoule dans le support, la connexion électrique de l'ampoule n'est plus garantie, voire plus possible. L'introduction de l'ampoule dans le support peut également être rendue impossible par la déformation des lames 206.Thus, once the bulb has been deposited, the blades 206 remain in a deformed state represented at figure 12 . As a result, the tampering means is activated during the removal or removal of the bulb and it alters during this operation the electrical connection means. If we try to reinsert the bulb in the holder, the electrical connection of the bulb is no longer guaranteed, or even more possible. The introduction of the bulb into the support can also be made impossible by the deformation of the blades 206.

Le moyen de connexion électrique peut aussi comprendre certaines lames 214 permettant une connexion électrique et n'étant pas altérées par la dépose ou le retrait de l'ampoule.The electrical connection means may also include some blades 214 for electrical connection and not being altered by the removal or removal of the bulb.

Un troisième mode de réalisation du support 300 d'ampoule selon l'invention est décrit ci-après en référence aux figures 13a, 13b et 14 à 17.A third embodiment of the bulb holder 300 according to the invention is described below with reference to Figures 13a, 13b and 14 to 17 .

Le support 300 comprend principalement une embase 301 et un fût 302 présentant les mêmes fonctions que celles décrites en relation avec le premier mode de réalisation.The support 300 mainly comprises a base 301 and a shaft 302 having the same functions as those described in relation to the first embodiment.

Le fût comprend de préférence un moyen 304, 303 de fixation ou de maintien mécanique de l'ampoule 10 sur le support et un moyen 306 de connexion électrique de l'ampoule.The barrel preferably comprises a means 304, 303 for fixing or mechanical support of the bulb 10 on the support and a means 306 for the electrical connection of the bulb.

Le moyen de fixation ou de maintien mécanique de l'ampoule permet de positionner l'ampoule relativement au support et de maintenir celle-ci dans cette position. Par exemple, le moyen de fixation mécanique comprend des clips 304 en forme de crochets présentant des épaulements 320 et destinés à coopérer avec une forme prévue sur l'ampoule, notamment un épaulement 13 prévu sur l'ampoule, en particulier prévu sur le culot 12 de l'ampoule. Ainsi, lors de l'introduction ou du montage de l'ampoule dans le support, les clips sont déformés élastiquement jusqu'à ce que l'épaulement 13 vienne en arrière des épaulements 320. Une fois dans cette position, les clips sont rappelés élastiquement dans leur position d'origine dans laquelle les épaulements 13 et 320 coopèrent pour empêcher la dépose ou le retrait de l'ampoule. Le moyen de fixation ou de maintien mécanique peut aussi comprendre un détrompeur comme une nervure destinée à coopérer avec une rainure prévue sur le culot de l'ampoule.The means for fixing or holding the ampoule mechanically makes it possible to position the bulb relative to the support and to hold the latter in this position. For example, the mechanical fastening means comprises clips 304 in the form of hooks having shoulders 320 and intended to cooperate with a shape provided on the bulb, in particular a shoulder 13 provided on the bulb, in particular provided on the base 12 of the bulb. Thus, during the introduction or mounting of the bulb in the support, the clips are elastically deformed until the shoulder 13 comes back from the shoulders 320. Once in this position, the clips are elastically recalled in their original position in which the shoulders 13 and 320 cooperate to prevent the removal or removal of the bulb. The fixing or mechanical holding means may also comprise a polarizer such as a rib intended to cooperate with a groove provided on the base of the bulb.

Le moyen 306 de connexion électrique de l'ampoule comprend au moins deux contacts électriques 306 destinés à coopérer avec au moins deux contacts électriques prévus sur l'ampoule, notamment sur le culot 12 de l'ampoule. De préférence, les contacts électriques du moyen de connexion électrique comprennent des lames 306, par exemple des lames métalliques, destinées à être reliées électriquement à une source d'énergie électrique permettant d'activer l'ampoule. De préférence, les lames comprennent au moins une pliure 313 et une portion repliée 319 terminée par une extrémité 312.The means 306 for electrical connection of the bulb comprises at least two electrical contacts 306 intended to cooperate with at least two electrical contacts provided on the bulb, in particular on the base 12 of the bulb. Preferably, the electrical contacts of the electrical connection means comprise blades 306, for example metal blades, intended to be electrically connected to a source of electrical energy for activating the bulb. Preferably, the blades comprise at least one fold 313 and a folded portion 319 terminated by an end 312.

Le support 300 comprend aussi un moyen 312 d'altération du moyen de connexion électrique de l'ampoule. Le moyen d'altération comprend par exemple principalement les extrémités 312 évoquées précédemment. Le moyen d'altération est destiné à coopérer avec une forme prévue sur l'ampoule, notamment des épaulements 16 prévus sur l'ampoule, en particulier prévu sur le culot 12 de l'ampoule. Ainsi, lors de l'introduction ou du montage de l'ampoule dans le support, les lames sont déformées élastiquement jusqu'à ce que les épaulements 16 viennent en arrière des extrémités 312 des lames. Une fois dans cette position, les lames sont rappelées élastiquement vers leurs positions d'origines. Ainsi, les épaulements 16 et les extrémités 312 coopèrent pour empêcher la dépose ou le retrait de l'ampoule et des portions 314 des lames sont en appui contre des contacts électriques prévus sur l'ampoule. Néanmoins, si on force sur l'ampoule pour la déposer ou la retirer comme représenté aux figures 15 à 17, les épaulements 16 du culot de l'ampoule exercent, par obstacle, une action mécanique sur les extrémités 312 et provoquent un arrachement des lames 306 comme représenté aux figures 15 à 17. En effet, les lames sont de préférence insérées en force dans des rainures 380 du fût dans lesquelles elles sont maintenues par l'action d'une ou plusieurs lamelles élastiques 321. De préférence, lors de l'arrachement des lames, les lamelles élastiques 321 détériorent localement les rainures, par exemple en arrachant de la matière.The support 300 also comprises means 312 for altering the electrical connection means of the bulb. The alteration means comprises for example mainly the ends 312 mentioned above. The alteration means is intended to cooperate with a shape provided on the bulb, including shoulders 16 provided on the bulb, in particular provided on the base 12 of the bulb. So, when introducing or mounting the bulb in the support, the blades are deformed elastically until the shoulders 16 come back from the ends 312 of the blades. Once in this position, the blades are resiliently returned to their original positions. Thus, the shoulders 16 and the ends 312 cooperate to prevent the removal or removal of the bulb and portions 314 of the blades bear against electrical contacts provided on the bulb. Nevertheless, if you force on the bulb to remove it or remove it as shown in Figures 15 to 17 , the shoulders 16 of the base of the bulb exert, by obstacle, a mechanical action on the ends 312 and cause tearing of the blades 306 as shown in FIGS. Figures 15 to 17 . Indeed, the blades are preferably inserted into force in grooves 380 of the barrel in which they are held by the action of one or more resilient lamellae 321. Preferably, during the tearing of the blades, the elastic lamellae 321 locally degrade the grooves, for example by tearing off the material.

Ainsi, une fois l'ampoule déposée, les lames 306 sont arrachées. En conséquence, le moyen d'altération est activé lors de la dépose ou du retrait l'ampoule et il altère au cours de cette opération le moyen de connexion électrique. Si on tente de réinsérer les lames dans le fût du support, leur maintien mécanique dans celui-ci n'est plus suffisant du fait de la détérioration des rainures. Ainsi, si on tente de réinsérer l'ampoule dans le support, la connexion électrique de l'ampoule dans le support n'est plus garantie, voire plus possible.Thus, once the bulb deposited, the blades 306 are torn off. Consequently, the tampering means is activated during the removal or removal of the bulb and it alters during this operation the electrical connection means. If one attempts to reinsert the blades into the support shaft, their mechanical retention therein is no longer sufficient because of the deterioration of the grooves. Thus, if we try to reinsert the bulb in the support, the electrical connection of the bulb in the support is no longer guaranteed, or even more possible.

Dans ce document, on entend par « moyen d'altération du moyen de connexion électrique », tout moyen permettant, lors de la dépose ou du retrait de l'ampoule du support d'ampoule, de modifier le moyen de connexion électrique, notamment par démontage ou arrachement d'un élément du moyen de connexion et/ou par déformation (en particulier par déformation plastique) d'un élément du moyen de connexion et/ou par détérioration d'un élément du moyen de connexion (en particulier rupture d'un élément du moyen de connexion et/ou enlèvement de matière sur un élément du moyen de connexion, plus généralement sur un élément du support).In this document, the term "means of alteration of the electrical connection means" means any means allowing, during removal or removal of the ampoule from the bulb holder, to modify the electrical connection means, in particular by means of disassembly or tearing of an element of the connection means and / or by deformation (in particular by plastic deformation) of an element of the connection means and / or by deterioration of an element of the connecting means (in particular breaking of an element of the connection means and / or removal of material on an element of the connection means, more generally on a support element).
