Description

Connecteur électrique pour injecteur de carburant DOMAINE TECHNIQUE  Electrical connector for fuel injector TECHNICAL DOMAIN
La présente invention est relative au connecteur électrique d'un injecteur de carburant et plus particulièrement aux cosses.  The present invention relates to the electrical connector of a fuel injector and more particularly to the lugs.
ARRIERE-PLAN TECHNOLOGIQUE DE L'INVENTION BACKGROUND OF THE INVENTION
Les injecteurs de carburant sont pourvus d'actuateurs pilotés tels des électroaimants communément arrangés à mi- hauteur de F injecteur. La connexion électrique de la bobine parcoure donc la partie supérieure du corps de l'injecteur et en ressort pour former le connecteur extérieur. Cela ajoute des connexions électriques et, dans la mesure d'une optimisation permanente de l'encombrement et des performances il est intéressant de proposer un dispositif de connexion fiable et de petite dimension.  The fuel injectors are provided with piloted actuators such as electromagnets commonly arranged at half the height of the injector. The electrical connection of the coil thus traverses the upper part of the body of the injector and comes out to form the outer connector. This adds electrical connections and, in the measure of a permanent optimization of the congestion and the performances it is interesting to propose a device of reliable connection and of small dimension.
RESUME DE L'INVENTION SUMMARY OF THE INVENTION
La présente invention vise à résoudre ces problèmes en proposant une cosse électrique plate réalisée à partir d'une plaque métallique ayant une épaisseur de cosse et dont une extrémité est délimitée par un premier bord au centre duquel débouche une fente s'étendant selon un axe principal. La fente permet l'enfichage complémentaire et la connexion électrique d'une autre cosse plate électriquement reliée à un dispositif. Les deux côtés opposés de la fente sont pourvus de protubérances chacune s'étendant en direction du côté opposé de sorte que ladite autre cosse est prévue pour être en contact avec les sommets des protubérances.  The present invention aims to solve these problems by proposing a flat electrical lug made from a metal plate having a thimble thickness and an end of which is delimited by a first edge in the center of which opens a slot extending along a main axis. . The slot allows complementary plugging and electrical connection of another flat lug electrically connected to a device. The two opposite sides of the slot are provided with protuberances each extending towards the opposite side so that said other lug is intended to be in contact with the tops of the protuberances.
De plus, les protubérances d'un côté sont arrangées en quinconce de celles du côté opposé de sorte qu'une protubérance soit face à une vallée entre deux protubérances.  In addition, the protuberances on one side are staggered from those on the opposite side so that a protuberance faces a valley between two protuberances.
De plus, un des côtés de la fente a au moins deux protubérances tandis que le côté opposé en a au moins une.  In addition, one side of the slot has at least two protuberances while the opposite side has at least one.
La ligne médiane de la fente est une ligne ondulée, la fente étant de largeur constante autour de cette ligne ondulée, les ondulations formant les protubérances et des vallées. Les lignes joignant les sommets des protubérances des côtés sont deux droites parallèles séparées l'une de l'autre d'une distance inférieure à l'épaisseur de la cosse. The median line of the slit is a wavy line, the slit being of constant width around this undulating line, the undulations forming the protuberances and valleys. The lines joining the tops of the protuberances sides are two parallel straight lines separated from each other by a distance less than the thickness of the lug.
Le premier bord de la cosse délimite un tronçon interne de la cosse qui s'inscrit substantiellement dans un premier plan. La cosse comprend également un tronçon externe distant destiné à recevoir un connecteur électrique en un agencement complémentaire de sorte à assurer l'alimentation électrique dudit dispositif. Le tronçon externe s'inscrit substantiellement dans un second plan.  The first edge of the pod delimits an inner section of the pod that is substantially in a foreground. The lug also includes a remote external section for receiving an electrical connector in a complementary arrangement so as to provide power to said device. The external section is substantially part of a second plan.
Particulièrement, le premier plan et le second plan sont perpendiculaires, la plaque ayant été tordue en un tronçon intermédiaire.  In particular, the first plane and the second plane are perpendicular, the plate having been twisted into an intermediate section.
L'invention est également relative à un connecteur électrique comprenant une enveloppe en plastique dans laquelle est surmoulée, ou insérée, au moins une cosse réalisée les paragraphes précédents, la cosse émergeant de deux côtés de l'enveloppe.  The invention also relates to an electrical connector comprising a plastic envelope in which is molded, or inserted, at least one pod made the preceding paragraphs, the pod emerging from two sides of the envelope.
De plus, l'invention est relative à un injecteur de carburant comprenant un actionneur électriquement relié à un connecteur réalisé selon le paragraphe précédent.  In addition, the invention relates to a fuel injector comprising an actuator electrically connected to a connector made according to the preceding paragraph.

DESCRIPTION DES MODES DE REALISATION PREFERES DESCRIPTION OF THE PREFERRED EMBODIMENTS
Selon la figure 1 un injecteur 10 de carburant s'étend selon la direction générale d'un axe principal Al . L'injecteur 10 est pourvu d'un actionneur 12 par exemple un électroaimant. En bas, dans le sens conventionnel de la figure 1 sans que ce choix soit limitatif de l'invention, l'injecteur 10 est conventionnellement pourvu d'une aiguille hydrauliquement pilotée pour obturer ou ouvrir des trous d'injection par lesquels le carburant est pulvérisé dans une chambre de According to Figure 1 a fuel injector 10 extends in the general direction of a main axis Al. The injector 10 is provided with an actuator 12, for example an electromagnet. Bottom, in the conventional sense of FIG. 1, without this choice being limiting of the invention, the injector 10 is conventionally equipped with a hydraulically driven needle for closing or opening injection holes through which the fuel is sprayed into a chamber of
combustion. L'actionneur 12 est électriquement relié à un conducteur interne 14 s'étendant selon la direction de l'axe principal Al jusqu'en haut, toujours dans le sens conventionnel de la figure 1, de l'injecteur 10. A son sommet, le conducteur interne 14 est pourvu d'une cosse 16 plate de liaison. La cosse 16 de liaison est métallique, rectangulaire et est d'une épaisseur El 6. Elle est agencée en contact avec une cosse externe 18 partie au connecteur 20 électrique de l'injecteur 10. combustion. The actuator 12 is electrically connected to an inner conductor 14 extending in the direction of the main axis A1 to the top, always in the conventional direction of FIG. 1, of the injector 10. At its apex, the internal conductor 14 is provided with a flat terminal lug 16. The connection lug 16 is metallic, rectangular and has a thickness El 6. It is arranged in contact with an outer lug 18 that is part of the electrical connector 20 of the injector 10.
La cosse externe 18 est maintenant décrite en référence aux figures 2 et 3. La cosse externe 18 est réalisée à partir d'une plaque métallique d'épaisseur El 8 et est mise en forme de sorte à comprendre un tronçon interne 22 prévu pour être en connexion électrique avec la cosse 16 de liaison, un tronçon externe 24, prévu pour être en connexion électrique avec une fiche électrique complémentaire de sorte à ainsi transmettre le courant électrique vers l'actionneur 12. Entre les tronçons internes 22 et externes 24, la cosse externe 18 comprend un tronçon intermédiaire 26 où sont concentrées des déformations de la cosse externe 18. Ainsi les tronçons interne 22 et externe 24 sont tous deux plats et de même épaisseur El 8 mais sont respectivement inscrits dans deux plans interne PI et externe PE distincts. Dans un repère à trois axes orthogonaux représentés sur la figure 2 et comprenant l'axe principal Al, un second axe A2 et, un troisième axe A3, le plan interne PI est normal au troisième axe A3 tandis que le plan externe PE est normal à l'axe principal Al . Tel qu'observable sur l'exemple de la figure 2 la plaque métallique qui a servi à la réalisation de la cosse externe 18 a une forme en L, chacune des branches correspondant à un tronçon interne 22 ou externe 24. La plaque a ensuite subit une torsion de 90° selon le second axe A2 de sorte que le tronçon externe 24 se trouve perpendiculaire au plan PI du tronçon interne 22. Tel qu'observable sur la figure 2, le tronçon intermédiaire 26 est une zone de section légèrement affaiblie de sorte que la déformation s'y trouve concentrée. Il va de soi que la forme donnée à la cosse externe 18 et ci-dessus décrite n'est qu'un exemple illustratif et toute autre forme est réalisable.  The outer lug 18 is now described with reference to FIGS. 2 and 3. The outer lug 18 is made from a metal plate of thickness El 8 and is shaped so as to comprise an internal section 22 intended to be electrical connection with the connecting lug 16, an external section 24, provided to be in electrical connection with a complementary electrical plug so as to transmit the electric current to the actuator 12. Between the inner and outer sections 22 and 24, the lug external 18 comprises an intermediate section 26 in which deformations of the outer lug 18 are concentrated. Thus, the inner and outer sections 22 and 24 are both flat and of the same thickness E1, but are respectively inscribed in two separate internal planes PI and outer PE. In a reference to three orthogonal axes shown in FIG. 2 and comprising the main axis A1, a second axis A2 and a third axis A3, the internal plane P1 is normal to the third axis A3 while the external plane PE is normal to the main axis Al. As can be observed in the example of FIG. 2, the metal plate that was used to make the outer lug 18 has an L-shaped shape, each of the branches corresponding to an inner or outer portion 24. The plate then undergoes a torsion of 90 ° along the second axis A2 so that the outer section 24 is perpendicular to the plane PI of the inner section 22. As seen in Figure 2, the intermediate section 26 is a slightly weakened section area so that that the deformation is concentrated there. It goes without saying that the shape given to the outer lug 18 and described above is only an illustrative example and any other form is feasible.
L'enfîchage complémentaire de la cosse de liaison 16 et de la cosse externe 18 se fait au niveau du tronçon interne 22 qui, tel que visible sur la figure 2 et particulièrement détaillé sur la figure 3, est pourvu d'une fente 28 s'étendant substantiellement selon l'axe principal Al depuis environ le milieu du tronçon interne 22 jusqu'au centre du bord inférieur du tronçon interne 22. Le bord inférieur s'étend en bas de la cosse externe 18 selon le second axe A2. The additional plugging of the connecting lug 16 and the outer lug 18 is at the inner portion 22 which, as shown in Figure 2 and particularly detailed in Figure 3, is provided with a slot 28 s'. extending substantially along the main axis A1 from about the middle of the inner section 22 to the center of the lower edge of the inner section 22. The lower edge extends down the outer lug 18 along the second axis A2.
Selon un premier mode de réalisation représenté, la fente 28 suit une ligne ondulée et est de largeur L constante. Ainsi formée la fente 28 comprend deux côtés 30 ondulés et parallèles. Les parties convexes forment des  According to a first embodiment shown, the slot 28 follows a wavy line and is of constant width L. Thus formed the slot 28 comprises two corrugated and parallel sides. The convex parts form
protubérances 32 alternées avec des parties concaves formant des vallées 34. Ainsi, les protubérances 32 d'un côté 30 sont face à des vallées 34 de l'autre côté 30. De plus les ondulations sont régulières et, par les sommets des protubérances 32 d'un côté 30 passe une première droite fictive 36 s 'étendant selon l'axe principal Al et, par les sommets des protubérances 32 de l'autre côté 30 passe une seconde droite fictive 38 parallèle à la première droite 36. Les deux droites 36, 38, sont séparées d'une distance D mesurée selon le second axe A2. protuberances 32 alternating with concave portions forming valleys 34. Thus, the protuberances 32 on one side 30 face valleys 34 on the other side 30. In addition, the corrugations are regular and, by the vertices of the protuberances 32 d a side 30 passes a first notional line 36 extending along the main axis Al and, by the vertices of the protuberances 32 on the other side 30 passes a second imaginary line 38 parallel to the first line 36. The two straight lines 36 , 38, are separated by a distance D measured along the second axis A2.
La cosse de liaison 16 peut ainsi s'enficher dans la fente 28 en n'étant en contact qu'avec les sommets des protubérances 32, l'épaisseur E16 de la cosse de liaison 16 étant juste supérieure à la distance D de séparation des droites 36, 38, une léger écartement élastique de la fente 28 permet l'enfichage complémentaire de la cosse de liaison 16.  The connecting lug 16 can thus be plugged into the slot 28 by being in contact only with the tops of the protuberances 32, the thickness E16 of the connecting lug 16 being just greater than the separation distance D of the straight lines 36, 38, a slight elastic separation of the slot 28 allows the complementary insertion of the connecting lug 16.
Selon une alternative non représentée à ce mode de réalisation, la fente 28 peut être réalisée droite mais pourvue de protubérances alternées.  According to an alternative not shown in this embodiment, the slot 28 can be made straight but provided with alternating protuberances.
Il est maintenant bien compris que ces protubérances permettent le maintien de la cosse de liaison 16. Au minimum, un côté 30 de la fente 28 n'aura qu'une protubérance 32 et fera face à l'autre côté 30 qui lui aura deux  It is now well understood that these protuberances allow the maintenance of the connecting lug 16. At least one side 30 of the slot 28 will have only one protrusion 32 and will face the other side 30 which will have two
protubérances 32. La cosse de liaison 16, une fois enfichée dans la fente 28, sera en contact en trois points, correspondant aux trois sommets. Un nombre supérieur de protubérances est bien sûr possible. protuberances 32. The connecting lug 16, once plugged into the slot 28, will be in contact at three points, corresponding to the three vertices. A higher number of protuberances is of course possible.
L'exemple choisi d'une cosse pour un injecteur de carburant n'est pas non plus limitatif de l'emploi possible de la cosse.  The chosen example of a lug for a fuel injector is also not limiting the possible use of the lug.
Du point de vue dimensionnel, la distance D entre les droites 36 est plus petite que la largeur L et également plus petite que l'épaisseur El 8 de la cosse 18 externe.  From a dimensional point of view, the distance D between the straight lines 36 is smaller than the width L and also smaller than the thickness El 8 of the outer lug 18.
Selon la figure 4, le connecteur 20 est représenté. Il comprend deux cosses 18 externes pour l'alimentation de l'actionneur 12. Le connecteur 20 est en plastique moulé et les tronçons internes 22 et externes 24 dépassent de part et d'autre du connecteur 20. According to Figure 4, the connector 20 is shown. It includes two external lugs 18 for supplying the actuator 12. The connector 20 is molded plastic and the inner and outer portions 22 and 24 protrude from either side of the connector 20.
