Abstract

The lamp holder includes a cylindrical body (30) which defines a cavity (CV) for the lamp cap (C1), and the grooves (31,32) are arranged diametrically opposite or at 150 degrees to one another. The former is used for a clear lamp and the latter for a tinted one. The strip (10) is recessed in its entirety relative to the cavity and makes contact with the base of the lamp. The strip crosses the gap in the body and is anchored by two approximately parallel clips (11) on either side of the strip. The clips comprise an angled prong cut from and standing proud of the associated surface. One end (12) of the strip makes contact with the external circuit and the holder is mounted on a base.

Description

La présente invention concerne d'une façon générale le montage des lampes dans des feux de signalisation notamment de véhicules automobiles.The present invention relates generally to the mounting of lamps in signaling lights, in particular of motor vehicles.

De façon classique, les lampes de feux de signalisation sont des lampes à baïonette, qui sont montées dans une plaque porte-lampe isolante sur laquelle sont fixées des pièces métalliques de contact et de raccordement avec un connecteur d'alimentation. De façon également classique, un tel porte-lampe est apte à recevoir un ensemble de lampes correspondant aux différentes fonctions lumineuses de signalisation.Conventionally, the signal light lamps are bayonet lamps, which are mounted in an insulating lamp holder plate on which are fixed metallic contact and connection pieces with a power connector. Also conventionally, such a lamp holder is capable of receiving a set of lamps corresponding to the various light signaling functions.

On a développé récemment des porte-lampes individuels, un tel porte-lampe comportant un corps isolant généralement cylindrique apte à être monté, en portant la lampe, dans une ouverture du socle du feu de signalisation. Un tel porte-lampe porte des pièces conductrices aptes à établir un contact d'une part intérieurement avec la lampe, au niveau d'une cavité de réception du culot de lampe, et d'autre part d'un côté extérieur du porte-lampe, mais à l'intérieur du socle, avec des éléments de contact fixés sur le socle et eux-mêmes reliés à un connecteur d'alimentation.Individual lamp holders have recently been developed, such a lamp holder comprising a generally cylindrical insulating body capable of being mounted, while carrying the lamp, in an opening in the base of the signaling light. Such a lamp holder carries conductive parts capable of establishing contact on the one hand internally with the lamp, at a cavity for receiving the lamp base, and on the other hand on an external side of the lamp holder , but inside the base, with contact elements fixed on the base and themselves connected to a power connector.

Les figures 1 et 2 représentent schématiquement deux porte-lampe de ce type.Figures 1 and 2 schematically show two lamp holders of this type.

Ils sont tous deux destinés à recevoir une lampe normalisée L1 à bulbe incolore, dont le culot C1 est représenté sur la figure 3 et comporte deux ergots E1 et E2 diamétralement opposés.They are both intended to receive a standard lamp L1 with a colorless bulb, the base C1 of which is shown in FIG. 3 and comprises two diametrically opposite lugs E1 and E2.

A cet effet, le porte-lampe PL de la figure 1 comporte dans un corps cylindrique creux 30 deux encoches 31 et 32 en forme générale de J, diamétralement opposées, destinées à recevoir les ergots. Pour établir le contact avec le corps du culot de la lampe (masse), le porte-lampe comporte une pièce conductrice de contact 20 en forme générale de "U", à cheval sur le bord du corps cylindrique creux du porte-lampe et comportant une partie de réunion 23, un premier bossage externe 21 et un second bossage interne 22 destiné à venir en contact latéralement avec le culot. Le bossage externe 21 est destiné quant à lui à venir au contact d'une pièce conductrice fixe (non représentée), solidaire du socle du feu, lors de la mise en place du porte-lampe.To this end, the lamp holder PL of FIG. 1 comprises in a hollow cylindrical body 30 two notches 31 and 32 in the general shape of J, diametrically opposite, intended to receive the pins. To establish contact with the body of the lamp base (ground), the lamp holder comprises a conductive contact piece 20 in the general shape of "U", straddling the edge of the hollow cylindrical body of the lamp holder and comprising a joining part 23, a first external boss 21 and a second internal boss 22 intended to come into contact laterally with the base. The external boss 21 is intended for its part to come into contact with a fixed conductive part (not shown), integral with the base of the light, when the lamp holder is put in place.

Pour le contact avec le plot du culot, il est prévu une autre pièce conductrice 10 qui est également représentée en vue de profil sur la figure 1. Cette pièce comporte une branche rectiligne 11 dans laquelle est formé, par découpage, un bossage 12 saillant vers l'extérieur. La branche 11 se termine par une partie transversale sinueuse 13 formant ressort et se plaçant au fond de la cavité CV de réception du culot.For contact with the stud of the base, another conductive part 10 is provided, which is also shown in profile view in FIG. 1. This part comprises a straight branch 11 in which is formed, by cutting, a boss 12 projecting towards outside. The branch 11 ends in a sinuous transverse part 13 forming a spring and being placed at the bottom of the cavity CV for receiving the base.

La pièce 10 est fixée sur le corps 30 du porte-lampe par le fait que sa branche rectiligne 11 est engagée dans une gorge 36 formée axialement dans la paroi du corps 30. Cette gorge est en l'espèce décalée angulairement par rapport à la pièce 20 d'un angle d'environ 135°, et est décalée de la première encoche 31 pour ergot d'une valeur également voisine de 135°.The part 10 is fixed to the body 30 of the lamp holder by the fact that its rectilinear branch 11 is engaged in a groove 36 formed axially in the wall of the body 30. This groove is in this case angularly offset with respect to the part 20 by an angle of about 135 °, and is offset from the first notch 31 for the lug by a value also close to 135 °.

La figure 4 des dessins montre un culot C2 d'une lampe normalisée L2. Cette lampe se distingue d'une lampe ayant le culot C1 par le fait que son bulbe est teinté pour donner un éclairement ambre, et par le fait que ses deux ergots E3 et E4 sont décalés angulairement de 150°.Figure 4 of the drawings shows a base C2 of a standard lamp L2. This lamp is distinguished from a lamp having the base C1 by the fact that its bulb is tinted to give an amber illumination, and by the fact that its two lugs E3 and E4 are angularly offset by 150 °.

On comprend que, du fait de la largeur relativement importante de la gorge 36 du corps 30 du porte-lampe de la figure 1, une lampe du type de L2 pourrait facilement être engagée dans ce porte-lampe, l'ergot E3 s'engageant dans l'encoche 31 tandis que l'ergot E4 s'engagerait dans la gorge 36, avec un verrouillage imparfait et, si l'ergot E4 est très saillant, un risque de court-circuit entre celui-ci, relié à la masse, et la pièce conductrice 10, reliée à la tension de batterie.It is understood that, due to the relatively large width of the groove 36 of the body 30 of the lamp holder of Figure 1, a lamp of the L2 type could easily be engaged in this lamp holder, the lug E3 engaging in the notch 31 while the lug E4 would engage in the groove 36, with an imperfect locking and, if the lug E4 is very protruding, a risk of short-circuit between it, connected to ground, and the conductive part 10, connected to battery voltage.

Ceci est bien entendu tout à fait indésirable, le porte-lampe PL de la figure 1 étant seulement destiné à recevoir une lampe dont le culot est celui de la figure 3.This is of course completely undesirable, the lamp holder PL of FIG. 1 being only intended to receive a lamp whose base is that of FIG. 3.

Pour pallier cette difficulté, on connaît une variante du porte-lampe de la figure 1, qui est illustrée sur la figure 2. Selon cette variante, la pièce conductrice 10 présente en lieu et place de la branche 11 une partie en "U" engagée dans la gorge 36 et constituée d'une partie de réunion 11b, d'une branche rectiligne externe 11c portant le bossage externe 12, et d'une branche rectiligne interne 11a à l'extrémité de laquelle est formée la partie formant ressort 13.To overcome this difficulty, a variant of the lamp holder of FIG. 1 is known, which is illustrated in FIG. 2. According to this variant, the conductive part 10 has instead of the branch 11 a "U" -shaped part engaged in the groove 36 and consisting of a joining part 11b, of an external rectilinear branch 11c carrying the external boss 12, and of an internal rectilinear branch 11a at the end of which the spring part 13 is formed.

Cette variante a pour objet d'empêcher effectivement l'engagement d'un culot du type de celui de la figure 4, dans la mesure où la branche rectiligne interne 11a de la pièce conductrice 10 vient sensiblement dans le prolongement de la face interne du corps cylindrique 30 et empêche la pénétration de l'ergot E4 dans la gorge 36. Mais dans cette variante, le risque de court-circuit lors d'une tentative de montage d'une lampe du type de L2 est patent. En effet, alors que l'ergot E3 se positionnera dans l'encoche 31, l'ergot E4 relié à la masse viendra à coup sûr en contact avec le sommet 11b de la pièce 10 au potentiel positif.The object of this variant is to effectively prevent the engagement of a base of the type of that of FIG. 4, insofar as the internal rectilinear branch 11a of the conductive part 10 comes substantially in line with the internal face of the body cylindrical 30 and prevents the penetration of the lug E4 in the groove 36. But in this variant, the risk of short circuit during an attempt to mount a lamp of the L2 type is obvious. Indeed, while the lug E3 will be positioned in the notch 31, the lug E4 connected to the ground will certainly come into contact with the apex 11b of the part 10 with positive potential.

On connaît également une autre variante de ce porte-lampe, non illustrée, dans laquelle les pièces 10 et 20 sont décalées angulairement d'environ 150°, les encoches 31 et 32 étant toujours diamétralement opposées pour recevoir une lampe du type de L1. Dans ce cas, une tentative de mise en place d'une lampe du type de L2 risque de provoquer la venue en contact de l'ergot E3 avec le sommet de l'une des pièces 10 et 20, et la venue en contact de l'ergot E4 avec le sommet de l'autre pièce, pour provoquer là encore un court-circuit.Another variant of this lamp holder, not shown, is also known, in which the parts 10 and 20 are angularly offset by approximately 150 °, the notches 31 and 32 being always diametrically opposite to receive a lamp of the L1 type. In this case, an attempt to install a lamp of the L2 type risks causing the lug E3 to come into contact with the top of one of the pieces 10 and 20, and the coming into contact of the 'lug E4 with the top of the other part, again to cause a short circuit.

On connaît enfin par US-A-4 040 709 un porte-lampe selon le préambule de la revendication 1.Finally, US-A-4,040,709 discloses a lamp holder according to the preamble of claim 1.

Ce porte-lampe, qui permettrait de résoudre les problèmes de court-circuits évoqués ci-dessus, est en revanche désavantageux en ce que sa retenue sur le porte-lampe est effectuée par des moyens rudimentaires, sans véritable ancrage ferme.This lamp holder, which would solve the short-circuit problems mentioned above, is however disadvantageous in that its retention on the lamp holder is carried out by rudimentary means, without real firm anchoring.

En outre, la zone de retenue, formant en même temps zone de contact avec une pièce de contact extérieure présente à la fois une surface réduite et des bords saillants propices à créer un coincement lors de la mise en place du porte-lampe.In addition, the retaining zone, at the same time forming a zone of contact with an external contact part, has both a reduced surface and projecting edges which are favorable for creating a wedge when the lamp holder is put in place.

La présente invention vise à pallier ces inconvénients, et à proposer un porte-lampe dans lequel aucun risque de court-circuit n'existe lorsque l'on tente d'y monter une lampe présentant une répartition angulaire d'ergots incorrecte pour ce type de porte-lampe, et ceci avec un surcoût minime et une grande simplicité.The present invention aims to overcome these drawbacks, and to provide a lamp holder in which no risk of short circuit exists when an attempt is made to mount a lamp there having an incorrect angular distribution of lugs for this type of lamp holder, and this with a minimal additional cost and great simplicity.

Ainsi la présente invention propose un porte-lampe pour feu de signalisation ayant les particularités de la revendication 1.Thus, the present invention provides a lamp holder for a signaling light having the features of claim 1.

Des aspects préférés, mais non limitatifs, du porte-lampe selon l'invention sont définis dans les sous-revendications.Preferred, but not limiting, aspects of the lamp holder according to the invention are defined in the dependent claims.

L'invention propose également un feu de signalisation tel que défini dans la revendication 9.The invention also provides a signaling light as defined in claim 9.

D'autres aspects, buts et avantages de la présente invention apparaîtront mieux à la lecture de la description détaillée suivante d'une forme de réalisation préférée de celle-ci, donnée à titre d'exemple non limitatif et faite en référence au dessin annexé sur lequel, outre les figures 1 à 4 décrites ci-dessus en préambule :

  • la figure 5 est une vue en coupe axiale d'un porte-lampe selon l'invention,

  • la figure 7 est une vue en élévation d'une pièce conductrice du porte-lampe des figures 5 et 6, et
  • la figure 8 est une vue en perspective de la pièce conductrice de la figure 7.
Other aspects, aims and advantages of the present invention will appear better on reading the following detailed description of a preferred embodiment thereof, given by way of nonlimiting example and made with reference to the attached drawing on which, in addition to Figures 1 to 4 described above in the preamble:
  • FIG. 5 is a view in axial section of a lamp holder according to the invention,
  • Figure 6 is a cross-sectional view of the lamp holder of figure 5,
  • FIG. 7 is an elevation view of a conductive part of the lamp holder of FIGS. 5 and 6, and
  • FIG. 8 is a perspective view of the conductive part of FIG. 7.

On notera préliminairement que, d'une figure à l'autre, des éléments ou parties identiques ou similaires sont désignés dans la mesure du possible par les mêmes signes de référence.It will be noted at the outset that, from one figure to another, identical or similar elements or parts are designated as far as possible by the same reference signs.

En référence aux figures 5 à 8, on a illustré un porte-lampe PL destiné à être monté dans une ouverture d'un socle de feu de signalisation de véhicule automobile et à recevoir une lampe L1 à ergots diamétralement opposés.Referring to Figures 5 to 8, there is illustrated a lamp holder PL intended to be mounted in an opening of a signal lamp base of a motor vehicle and to receive a lamp L1 with diametrically opposite lugs.

Le porte-lampe, réalisé de préférence par injection de matière plastique, comporte, de façon classique, une collerette périphérique 35 et porte un joint torique d'étanchéité J destiné à être pressé entre la collerette 35 et le socle lors du montage du porte-lampe dans ledit socle, ce montage étant assuré par des aménagements de verrouillage conventionnels.The lamp holder, preferably made by injection of plastic material, comprises, in a conventional manner, a peripheral flange 35 and carries an O-ring seal J intended to be pressed between the flange 35 and the base during assembly of the holder lamp in said base, this mounting being provided by conventional locking arrangements.

A l'extrémité libre côté lampe du corps cylindrique 30 du porte-lampe est montée une première pièce de contact en U (non représentée), telle qu'elle a été décrite plus haut, disposée à cheval sur la avec des bossages extérieur et intérieur. Le bossage extérieur, lors du montage du porte-lampe, est destiné à venir au contact d'un élément de contact fixe, monté sur le socle par des aménagements appropriés non illustrés et relié électriquement à un connecteur du feu de signalisation. Le bossage intérieur de cette première pièce forme contact de masse avec le culot de la lampe.At the free end on the lamp side of the cylindrical body 30 of the lamp holder is mounted a first U-shaped contact part (not shown), as described above, arranged astride the with external and internal bosses. . The external boss, during assembly of the lamp holder, is intended to come into contact with a fixed contact element, mounted on the base by suitable arrangements not shown and electrically connected to a connector of the signaling light. The interior boss of this first part forms earth contact with the base of the lamp.

Dans une région du corps 30 décalée angulairement d'environ 150° par rapport à la première pièce précitée est montée une autre pièce de contact 10. Cette pièce 10, illustrée en détail sur les figures 7 et 8, comprend une lame souple 13 de contact avec un plot axial de la lampe L1, qui s'étend sensiblement à angle droit à partir d'un corps 12 incurvé. De part et d'autre de ce corps s'étendent deux pattes d'ancrage 11 pourvues chacune d'une dent d'ancrage 11a débordant en oblique vers l'extérieur.In another region of the body 30 angularly offset by about 150 ° relative to the aforementioned first part, another contact part 10 is mounted. This part 10, illustrated in detail in FIGS. 7 and 8, comprises a flexible blade 13 in contact with an axial stud of the lamp L1, which extends substantially at right angles from a curved body 12. On either side of this body extend two anchoring tabs 11 each provided with an anchoring tooth 11a projecting obliquely outward.

Dans cette région, le corps 30 du porte-lampe définit une lumière allongée pour le passage de la languette souple 13, cette lumière débouchant, côté intérieur, sur la cavité CV pour le culot de la lampe et, côté extérieur, sur un renfoncement bordé latéralement par deux parois droites 36 généralement parallèles contre lesquelles les pattes d'ancrage 11 viennent s'appliquer élastiquement lors de la mise en place de la pièce 10, réalisée à force selon une direction généralement perpendiculaire à l'axe du porte-lampe, les dents 11a venant s'accrocher dans la matière des parois 36. On réalise ainsi un ancrage extrêmement efficace, avec une pièce qui reste simple et facile à monter.In this region, the body 30 of the lamp holder defines an elongated lumen for the passage of the flexible tongue 13, this lumen opening, on the interior side, onto the cavity CV for the lamp base and, on the exterior side, on a bordered recess laterally by two straight walls 36 generally parallel against which the anchoring lugs 11 are applied elastically during the establishment of the part 10, forcibly produced in a direction generally perpendicular to the axis of the lamp holder, the teeth 11a coming to hang in the material of the walls 36. An extremely effective anchoring is thus produced, with a part which remains simple and easy to assemble.

Dans la région centrale du renfoncement sont également formées deux parois généralement radiales 37 dont les bords extérieurs libres forment butées pour la pièce 10 lors de sa mise en place.In the central region of the recess, two generally radial walls 37 are also formed, the free outer edges of which form stops for the part 10 when it is put in place.

Après cette mise en place, la languette souple 13 s'étendant dans la région du fond de la cavité CV tient lieu de contact de plot de lampe, tandis que la face extérieure de la partie de liaison 12 tient lieu de contact avec un élément de contact fixe (non représenté) prévu sur le socle du feu et relié à un connecteur d'alimentation du feu.After this installation, the flexible tongue 13 extending in the region of the bottom of the cavity CV takes the place of contact with the lamp stud, while the external face of the connecting part 12 takes the place of contact with an element of fixed contact (not shown) provided on the light base and connected to a light supply connector.

La mise en place du porte-lampe dans le socle assure ainsi la connexion des pièces de contact 10 et 20 avec la tension d'alimentation et la masse disponibles sur le connecteur du feu.The installation of the lamp holder in the base thus ensures the connection of the contact parts 10 and 20 with the supply voltage and the earth available on the light connector.

Pour éviter l'engagement incorrect d'une lampe L2 dont le culot est illustré sur la figure 4, le bord de l'ouverture d'accès à la cavité CV au droit de la pièce de contact 10 est de préférence continu, ce qui est rendu possible par le fait que la pièce 10 est engagée radialement et intégralement situé en retrait par rapport à cette ouverture. De la sorte, la lampe du type de L2 ne peut pas être mise en place, et de surcroît aucun risque de court-circuitage n'existe du fait de la position en retrait de la pièce conductrice 10.To avoid incorrect engagement of an L2 lamp, the base of which is illustrated in FIG. 4, the edge of the access opening to the cavity CV to the right of the contact piece 10 is preferably continuous, which is made possible by the fact that the piece 10 is engaged radially and integrally set back with respect to this opening. In this way, the lamp of the L2 type cannot be put in place, and in addition no risk of short-circuiting exists due to the recessed position of the conductive part 10.

Bien entendu, la présente invention n'est nullement limitée à la forme de réalisation décrite et représentée, mais l'homme de l'art saura y apporter toute variante ou modification conforme à son esprit.Of course, the present invention is not limited to the embodiment described and shown, but those skilled in the art will be able to make any variant or modification in accordance with his spirit.
