Douille pour lampes électriques  Socket for electric lamps
Domaine de l' invention La présente invention concerne le domaine des douilles pour lampes électriques, en particulier les douilles pour automobiles. FIELD OF THE INVENTION The present invention relates to the field of sockets for electric lamps, in particular sockets for automobiles.
A titre d'exemple non limitatif, ces douilles sont destinées à recevoir des ampoules à baïonnette de type P 21 watt mono filament ou P21-5 bi filament.  By way of non-limiting example, these sockets are intended to receive bayonet bulbs type P 21 watt mono filament or P21-5 bi-filament.
Etat de la technique State of the art
On connaît dans l'état de la technique des douilles électriques constituées par un corps tubulaire isolant pourvu d'une ou deux lames électriques flexibles venant en contact avec la ou les gouttes de contact de l'ampoule. Ces lames électriques sont réalisées par découpe et pliage d'une feuille de bronze maillechort ou d'un alliage cuivreux.  Electrical sleeves are known in the state of the art consisting of an insulating tubular body provided with one or two flexible electrical blades coming into contact with the contact drop or drops of the bulb. These electric blades are made by cutting and folding a sheet of bronze nickel silver or a cuprous alloy.
On connaît également dans l'état de la technique de telles douilles munies d'un volet de verrouillage permettant de verrouiller l'assemblage des contacts électriques dans le corps de la douille.  Also known in the state of the art such sockets provided with a locking flap for locking the assembly of electrical contacts in the body of the sleeve.
Il est également connu de prévoir sur les contacts électriques des moyens de sécurité empêchant l'engagement du volet de verrouillage en cas d'assemblage défectueux.  It is also known to provide on the electrical contacts safety means preventing the engagement of the locking flap in case of faulty assembly.
Inconvénient de l'état de la technique Disadvantage of the state of the art
L'inconvénient des solutions de l'art antérieur concerne l'application de ces solutions à des douilles destinées à des ampoules destinées à un fonctionnement continu, dans des conditions climatiques défavorables (température élevées, exposition longue au soleil,...).  The disadvantage of the solutions of the prior art relates to the application of these solutions to sockets for bulbs intended for continuous operation, in adverse weather conditions (high temperature, long exposure to the sun, ...).
Dans de telles situations, le corps en matière plastique se dégrade en raison des températures élevées du culot de la lampe en contact avec le corps isolant.  In such situations, the plastic body degrades due to the high temperatures of the lamp base in contact with the insulating body.
Solution apportée par l'invention Solution provided by the invention
La solution apportée par la présente invention consiste à prévoir un insert métallique formé de deux ailes semi-tubulaires assurant outre l'alimentation électrique du culot de la lampe une évacuation thermique par convection. Afin d'assurer le positionnement correct de cet insert, l'invention concerne la présence d'oreilles interagissant avec le volet de verrouillage d'une manière empêchant le déplacement complet dudit volet. L'engagement imparfait de 1 'insert produit alors un positionnement manifestement et visiblement anormal du volet, alertant l'utilisateur d'une erreur d'assemblage. The solution provided by the present invention consists in providing a metal insert formed of two wings semi-tubular, in addition to supplying electrical power to the base of the lamp, a thermal evacuation by convection. In order to ensure the correct positioning of this insert, the invention relates to the presence of ears interacting with the locking flap in a manner preventing complete movement of said flap. The imperfect engagement of the insert then produces a clearly and visibly abnormal positioning of the shutter, alerting the user of an assembly error.
L'invention concerne selon son acception la plus générale une douille électrique pour ampoule électrique, comprenant un corps isolant, un insert métallique formant une masse électrique et au moins un contact électrique d'alimentation, ledit corps isolant étant muni d'un volet de verrouillage mobile entre une position permettant l'insertion dudit insert et dudit contact électrique, et une position de verrouillage empêchant le retrait desdits éléments, caractérisé en ce que ledit insert métallique est formé par une découpe dans un matériau métallique semi-élastique formant un fut constituée de deux ailes semi-tubulaires réunies par l'extrémité d'une patte de sertissage, et en ce que chacune desdites ailes semi-tubulaires sont prolongées à leur bord inférieur par des oreilles s 'étendant tangentiellement , pour former une butée limitant le déplacement du volet de verrouillage lorsque l' insert n'est pas complètement engagé et verrouillé dans ledit corps isolant.  The invention relates, in its most general sense, to an electric socket for a light bulb, comprising an insulating body, a metal insert forming an electrical mass and at least one electrical supply contact, said insulating body being provided with a locking flap. movable between a position allowing the insertion of said insert and said electrical contact, and a locking position preventing the withdrawal of said elements, characterized in that said metal insert is formed by a cut in a semi-elastic metal material forming a was formed of two semi-tubular wings joined by the end of a crimping tab, and in that each of said semi-tubular wings are extended at their lower edge by tangentially extending lugs, to form a stop limiting the movement of the flap when the insert is not fully engaged and locked in said body is olant.
On entend par « semi-élastique » au sens du présent brevet la caractéristique d'un matériau reprenant sa position d'origine après une déformation mineure, de moins de 10% de sa plus grande dimension, et conservant la position contrainte en cas de déformation dépassant ce seuil. A titre d'exemple, sera considéré comme « semi-élastique » au sens du présent brevet une pièce réalisée par découpe et pliage d'une feuille de laiton, de laiton étamé ou d'acier électro zingué.  The term "semi-elastic" in the sense of this patent means the characteristic of a material returning to its original position after a minor deformation, less than 10% of its largest dimension, and retaining the constrained position in case of deformation exceeding this threshold. For example, will be considered as "semi-elastic" in the sense of this patent a piece made by cutting and folding a sheet of brass, tinned brass or electro-galvanized steel.

La figure 1 représente une vue en écorché d'un exemple de réalisation d'une douille selon l'invention.  Figure 1 shows a cutaway view of an embodiment of a sleeve according to the invention.
La douille comprend un corps isolant (1) destiné à recevoir le culot (3) d'une ampoule (2) . Le corps isolant (1) est muni d'un volet mobile (4) de verrouillage.  The socket comprises an insulating body (1) for receiving the base (3) of a bulb (2). The insulating body (1) is provided with a movable movable flap (4).
Un insert (7) métallique assure l'alimentation de la masse formée par le culot (3) de l'ampoule (2) .  A metal insert (7) supplies the mass formed by the base (3) of the bulb (2).
Deux languettes métalliques (5, 6) assurent l'alimentation des gouttes de contact des deux filaments l'ampoule électrique.  Two metal tongues (5, 6) provide the contact drops of the two filaments with the electric bulb.
Ces languettes (5, 6) sont engagées dans des alvéoles (50, 60). Les languettes (5, 6) présentent à leur extrémité arrière des zones de sertissage (51, 61) pour le sertissage des fils d'alimentation. Ces zones de sertissage (51, 61) sont prolongées par un épaulement saillant (52, 62) assurant une fonction de détection d'éventuels défauts d'assemblage. Lorsque l'une des languettes (5, 6) n'est pas correctement engagée dans l'alvéole (50, 60), l'épaulement dépasse de la surface supérieur et empêche la fermeture du volet de verrouillage (4), ce qui rend manifeste et visible le défaut d'assemblage.  These tongues (5, 6) are engaged in cavities (50, 60). The tongues (5, 6) have at their rear end crimping areas (51, 61) for crimping the supply wires. These crimping zones (51, 61) are extended by a protruding shoulder (52, 62) providing a function for detecting any assembly defects. When one of the tabs (5, 6) is not correctly engaged in the recess (50, 60), the shoulder protrudes from the upper surface and prevents the closing of the locking flap (4), which makes manifest and visible the fault of assembly.
La figure 2 représente une vue en détail de 1 'insert. Il est formé par une feuille métallique découpée et mise en forme. Il présente deux ailes (8, 9) semi-tubulaires dont l'enveloppe présente une section légèrement supérieure à la cavité du corps (1), afin de permettre un positionnement dans la cavité par une déformation élastique. Figure 2 shows a detail view of the insert. It is formed by a cut metal sheet and formatting. It has two wings (8, 9) semi-tubular whose envelope has a slightly larger section to the body cavity (1), to allow positioning in the cavity by elastic deformation.
L'une des ailes (8) présente une cannelure (10) emboutie pour le passage de l'ergot latéral de l'ampoule à baïonnette. L'ergot opposé de l'ampoule est guidé par la fente (11) délimitée par les deux lèvres recourbées (12, 13) prolongeant les bords longitudinaux des ailes respectivement (8, 9) .  One of the wings (8) has a groove (10) stamped for the passage of the lateral lug of the bayonet bulb. The opposite lug of the bulb is guided by the slot (11) delimited by the two curved lips (12, 13) extending the longitudinal edges of the wings respectively (8, 9).
L'une des lèvres (12, 13) est prolongée par une butée (14) venant en appui sur la surface intérieure de la cavité longitudinale du corps.  One of the lips (12, 13) is extended by a stop (14) bearing on the inner surface of the longitudinal cavity of the body.
L'une des lèvres (12, 13) présente une lumière (15) pour le verrouillage de l'ergot du culot de l'ampoule à baïonnette .  One of the lips (12, 13) has a slot (15) for locking the lug of the base of the bayonet bulb.
Une deuxième lumière (19) diamétralement opposée est prévue sur l' insert, pour recevoir le deuxième ergot opposé du culot de l'ampoule, en particulier pour recevoir l'ergot fixe de l'ampoule.  A second diametrically opposite second lumen (19) is provided on the insert to receive the second opposite lug from the bulb base, in particular to receive the fixed lug of the bulb.
Les ailes (8, 9) présente chacune un nez de verrouillage (16, 17) assurant le maintien de l'insert (7) dans la cavité longitudinale du corps (1) .  The wings (8, 9) each have a locking nose (16, 17) ensuring the maintenance of the insert (7) in the longitudinal cavity of the body (1).
L'une des ailes (8) présente un détrompeur (18) positionné pour coopérer avec un moyen complémentaire prévu sur le corps (1) . La position de ce détrompeur est spécifique à un type d'ampoule. Il évite de monter dans un corps destiné à un type d'ampoule un insert destiné à une ampoule d'un autre type, par exemple de monter dans un corps destiné à une ampoule bi-filament un insert destiné à une ampoule mono filament .  One of the wings (8) has a polarizer (18) positioned to cooperate with a complementary means provided on the body (1). The position of this polarizer is specific to a type of bulb. It avoids mounting in a body for a type of bulb an insert for a bulb of another type, for example to mount in a body for a bi-filament bulb an insert for a single-filament bulb.
L'insert comprend également une zone de sertissage constituée par une jupe de sertissage du conducteur (20) reliée aux ailes (8, 9) par une patte de liaison (23) . La jupe de sertissage du conducteur (20) est prolongée par une jupe de sertissage de l'isolant (22) . Entre la jupe de sertissage du conducteur (20) et la jupe de sertissage de l'isolant (22) est prévue une barrette (21) venant se loger dans une alvéole (24) prévu sur le corps (1) . Les ailes (8, 9) présentent par ailleurs des prolongements protubérants en forme d'oreilles (25, 26). Ces oreilles (25, 26) s'étendent tangentiellement pour assurer une fonction de détection de positionnement. The insert also comprises a crimping zone consisting of a crimping skirt of the conductor (20) connected to the wings (8, 9) by a connecting lug (23). The crimping skirt of the conductor (20) is extended by a crimping skirt of the insulator (22). Between the crimping skirt of the conductor (20) and the crimping skirt of the insulator (22) is provided a bar (21) housed in a recess (24) provided on the body (1). The wings (8, 9) further have protruding projections in the form of ears (25, 26). These ears (25, 26) extend tangentially to provide a position detection function.
Les figures 3 et 4 montrent la douille en position de fermeture lorsque l'insert (7) est mal engagé. Dans ce cas, les oreilles (25, 26) vient obturer les glissières (27) venant guider le déplacement du volet (4) .  Figures 3 and 4 show the socket in the closed position when the insert (7) is badly engaged. In this case, the ears (25, 26) closes the slides (27) guiding the movement of the flap (4).
Les figures 5 et 6 montrent la douille en position de fermeture lorsque l'insert (7) est correctement engagé.  Figures 5 and 6 show the socket in the closed position when the insert (7) is properly engaged.
L'insert (7) pénètre suffisamment dans la cavité du corps (1) et les oreilles (25, 26) libère les glissières (27). Dans ce cas, le volet (4) peut être repoussé jusqu'au bout de sa course, pour occuper la position représentée sur les figures (7, 8) .  The insert (7) penetrates sufficiently into the body cavity (1) and the lugs (25, 26) releases the slides (27). In this case, the flap (4) can be pushed to the end of its stroke, to occupy the position shown in Figures (7, 8).
Le corps et le tiroir sont réalisés par moulage dans un seul moule présentant plusieurs tiroirs mobiles. La fabrication ne comporte pas d'étape d'assemblage d'un corps d'une part et d'un tiroir d'autre part les deux éléments étant moulés de manière pré-assemblée.  The body and the drawer are made by molding in a single mold having several movable drawers. The manufacture does not include a step of assembling a body on the one hand and a drawer on the other hand the two elements being molded in a pre-assembled manner.
La pièce articulée, formée d'un corps et d'un tiroir pré-assemblés , est moulée en position presque ouverte représentée en figure 9 et 10. Le tiroir n'est pas en position extrême de la course, afin de laisser subsister un jeu d'environ 0,4 millimètre permettant le passage d'une lame d'acier du moule.  The articulated part, formed of a pre-assembled body and a drawer, is molded in the almost open position shown in FIGS. 9 and 10. The drawer is not in the extreme position of the stroke, in order to leave a game about 0.4 millimeters allowing the passage of a steel blade from the mold.
Le moulage se fait avec une direction principale de déplacement du moule orienté transversalement, comme représenté par les flèches (30, 31) . L'injection selon la première direction de moulage (30) permet d'injecter la partie intérieure (32) du volet mobile (4) ainsi que la partie arrière du corps (1) .  The molding is done with a main direction of displacement of the mold oriented transversely, as represented by the arrows (30, 31). The injection in the first molding direction (30) injects the inner portion (32) of the movable flap (4) and the rear portion of the body (1).
Le moulage selon la deuxième direction de moulage (31) permet d'injecter la partie avant (33) du corps (1) et la partie frontale inférieure (34) du volet mobile (4) .  The molding in the second molding direction (31) is used to inject the front portion (33) of the body (1) and the lower end portion (34) of the movable flap (4).
Une deuxième direction de moulage est assurée par des tiroirs déplacés selon des directions opposées longitudinales (35, 36). Le tiroir déplacé selon la direction (35) définit la partie supérieure (37) du volet mobile, le système d'accrochage (38) du volet mobile et la zone complémentaire du corps (1), ainsi que l'intérieur de la partie arrière (39) du corps destinée à recevoir les contacts électriques. A second direction of molding is provided by drawers moved in opposite longitudinal directions (35, 36). The drawer moved in the direction (35) defines the upper part (37) of the movable flap, the attachment system (38) of the movable flap and the complementary area of the body (1), as well as the inside of the rear part. (39) of the body for receiving the electrical contacts.
Le tiroir déplacé selon la direction opposée (36) définit l'intérieur (40) de la partie avant du corps (1) .  The drawer moved in the opposite direction (36) defines the inside (40) of the front part of the body (1).
La pièce ainsi moulée est constituée de deux parties imbriquées, maintenus de manière inséparable notamment par le système d'accrochage (38) du volet mobile et la zone complémentaire du corps (1) . Ces deux parties sont néanmoins mobiles l'une par rapport à l'autre du fait des jeux et évidements prévues entre les surfaces des deux éléments.  The part thus molded consists of two nested parts, maintained inseparably, in particular by the attachment system (38) of the movable flap and the complementary zone of the body (1). These two parts are nevertheless movable relative to each other because of the games and recesses provided between the surfaces of the two elements.
