Description

CONNECTEUR ELECTRIQUE POUR VEHICULE AUTOMOBILE  ELECTRICAL CONNECTOR FOR MOTOR VEHICLE
La présente invention a pour objet un connecteur électrique pour véhicule automobile. Elle concerne en particulier un connecteur de puissance haute tension pour véhicule automobile électrique. The present invention relates to an electrical connector for a motor vehicle. It relates in particular to a high voltage power connector for an electric motor vehicle.
Un connecteur électrique est un composant placé à l'extrémité de conducteurs et qui permet de réaliser leur connexion ou déconnexion avec un autre composant approprié.  An electrical connector is a component placed at the end of conductors and which allows their connection or disconnection with another suitable component.
La puissance croissante des organes électriques, en particulier sur les véhicules automobiles, a pour conséquence des liaisons électriques dans lesquelles transitent des courants électriques de plus en plus puissants.  The increasing power of electrical components, particularly on motor vehicles, results in electrical connections in which more and more powerful electric currents pass.
Les éléments amovibles de ces liaisons électriques, les connecteurs, doivent satisfaire à plusieurs exigences.  The removable elements of these electrical connections, the connectors, must satisfy several requirements.
Le connecteur doit en premier lieu répondre à une exigence de sécurité. Les forts courants des liaisons électriques peuvent en effet électrocuter un utilisateur si le connecteur n'est pas suffisamment sécurisé.  The connector must first meet a security requirement. The strong currents of the electrical connections can indeed electrocute a user if the connector is not sufficiently secure.
Le connecteur doit ensuite être étanche, de manière à empêcher notamment l'entrée d'eau ou de déchets à l'intérieur du connecteur.  The connector must then be sealed, in particular to prevent the entry of water or waste into the connector.
Le connecteur doit bien sûr être démontable.  The connector must of course be removable.
Enfin, comme de forts champs magnétiques sont générés par les courants électriques, il doit également assurer une fonction de blindage électromagnétique autour des conducteurs.  Finally, since strong magnetic fields are generated by the electric currents, it must also provide an electromagnetic shielding function around the conductors.
On connaît des connecteurs répondant à ces exigences, comme par exemple le connecteur décrit dans le document WO 2008/127518.  Connectors meeting these requirements are known, such as the connector described in WO 2008/127518.
Ces connecteurs sont toutefois encombrants et onéreux.  These connectors are however bulky and expensive.
On connaît de la demande US 2010/0084205 un connecteur comprenant un boîtier ayant des ouvertures latérales par lesquelles des câbles pénètrent dans l'intérieur du boîtier et un capot amovible intégrant des moyens pour interrompre le courant dans les câbles lorsque le capot est enlevé. Ce connecteur ne comprend qu'un seul capot amovible.  Application US 2010/0084205 discloses a connector comprising a housing having lateral openings through which cables penetrate into the interior of the housing and a removable cover incorporating means for interrupting the current in the cables when the cover is removed. This connector includes only one removable cover.
On connaît de la demande DE 10 2007 037 356 un connecteur comprenant un boîtier ayant un premier capot amovible et un deuxième capot obturant l'ouverture par laquelle des câbles pénètrent à l'intérieur du boîtier, ce deuxième capot étant également amovible. Ce connecteur intègre des moyens pour interrompre le courant dans les câbles si l'un des capots est enlevé. Le boîtier est réalisé en un matériau électriquement isolant, ce qui pose des problèmes en termes de compatibilité électro-magnétique. Application DE 10 2007 037 356 discloses a connector comprising a housing having a first removable cover and a second cover closing the opening through which cables penetrate inside the housing, this second cover being also removable. This connector includes means for interrupting the current in the cables if one of the covers is removed. The housing is made of an electrically insulating material, which poses problems in terms of electromagnetic compatibility.
La présente invention vise à remédier aux inconvénients des connecteurs de l'art antérieur.  The present invention aims to overcome the disadvantages of connectors of the prior art.
Elle propose en particulier un connecteur électrique sécurisé, étanche, démontable et assurant un blindage électromagnétique autour des conducteurs, et qui est en même temps compact et de fabrication économique.  It proposes in particular a secure electrical connector, waterproof, removable and providing electromagnetic shielding around the conductors, and which is at the same time compact and economical manufacturing.
L'invention a ainsi pour objet un connecteur électrique pour véhicule automobile. Le connecteur électrique selon l'invention comprend :  The invention thus relates to an electrical connector for a motor vehicle. The electrical connector according to the invention comprises:
- un boîtier comprenant une zone de connexion électrique destinée à être connectée à au moins un conducteur, ledit boîtier étant muni d'une première ouverture permettant l'accès à la zone de connexion et d'une deuxième ouverture permettant le passage du ou des conducteurs,  a housing comprising an electrical connection zone intended to be connected to at least one conductor, said housing being provided with a first opening allowing access to the connection zone and a second opening allowing the passage of the conductor (s) ,
- un premier capot monté de manière amovible sur le boîtier et apte à recouvrir la première ouverture du boîtier,  a first cover removably mounted on the housing and able to cover the first opening of the housing,
- un deuxième capot monté de manière amovible sur le boîtier et apte à recouvrir la deuxième ouverture du boîtier, ledit deuxième capot comprenant au moins une ouverture permettant le passage du ou des conducteurs,  a second cover removably mounted on the housing and able to cover the second opening of the housing, said second cover comprising at least one opening allowing passage of the conductor or conductors,
le boîtier, le premier capot et le deuxième capot comprenant chacun une zone électriquement conductrice reliée électriquement aux autres zones conductrices en configuration opérationnelle du connecteur, de manière à former un blindage électromagnétique autour du ou des conducteurs, et the housing, the first cover and the second cover each comprising an electrically conductive zone electrically connected to the other conductive areas in the operational configuration of the connector, so as to form an electromagnetic shield around the conductor (s), and
- un système de commande apte à commander l'interruption du courant électrique parcourant le ou les conducteurs si une ouverture du premier capot est détectée.  - A control system adapted to control the interruption of the electric current flowing through the conductor or drivers if an opening of the first cover is detected.
La zone de connexion électrique peut être un bornier.  The electrical connection zone may be a terminal block.
Une cosse peut être fixée sur l'extrémité de chaque conducteur.  A lug can be attached to the end of each conductor.
Chaque cosse peut être vissée sur le bornier.  Each lug can be screwed on the terminal block.
Le deuxième capot peut être une pièce en matière plastique munie d'une zone conductrice.  The second cover may be a plastic part provided with a conductive area.
Le deuxième capot peut comprendre un passage pour chaque conducteur. Lors de l'assemblage du connecteur, le ou les conducteurs peuvent être préalablement introduits à l'intérieur des passages correspondants du deuxième capot avant que le deuxième capot ne soit rapporté sur le boîtier pour recouvrir la deuxième ouverture du boîtier. En variante, lors de l'assemblage du connecteur, on rapporte le deuxième capot sur le boîtier pour recouvrir la deuxième ouverture du boîtier puis on introduit les conducteurs dans les passages correspondants du deuxième capot. The second hood may include a passage for each driver. During assembly of the connector, the conductor or conductors may be introduced beforehand into the corresponding passages of the second cover before the second cover is attached to the housing to cover the second opening of the housing. Alternatively, when the connector assembly, the second cover is reported on the housing to cover the second opening of the housing and then introduced the conductors in the corresponding passages of the second cover.
Le système de commande peut être apte à commander l'interruption du courant électrique parcourant le ou les conducteurs si une ouverture du deuxième capot est détectée.  The control system may be able to control the interruption of the electric current flowing through the conductor or conductors if an opening of the second cover is detected.
Un joint d'étanchéité peut être disposé entre le boîtier et chaque capot ainsi qu'entre le ou les conducteurs et le deuxième capot.  A seal may be disposed between the housing and each hood and between the conductor (s) and the second hood.
Dans un exemple de mise en œuvre de l'invention, au moins une portion électriquement conductrice est rapportée sur le premier capot et le connecteur comprend au moins deux pattes ayant chacune une première extrémité reliée, directement ou non, à une unité de contrôle et une deuxième extrémité libre. Les pattes peuvent être disposées dans le boîtier de manière à ce que lorsque le premier capot est en place, leur extrémité libre vienne en appui contre la portion métallique rapportée sur le premier capot. Un isolant est notamment interposé entre la portion électriquement conductrice et le premier capot. L'isolant et la portion électriquement conductrice forment par exemple un circuit imprimé. Dans ce cas, la portion électriquement conductrice rapportée sur le premier capot correspond à une piste du circuit imprimé.  In an exemplary implementation of the invention, at least one electrically conductive portion is attached to the first cover and the connector comprises at least two tabs each having a first end connected, directly or indirectly, to a control unit and a connector. second free end. The tabs may be arranged in the housing so that when the first cover is in place, their free end comes into abutment against the metal portion attached to the first cover. An insulator is interposed interposed between the electrically conductive portion and the first cover. The insulator and the electrically conductive portion form for example a printed circuit. In this case, the electrically conductive portion reported on the first cover corresponds to a printed circuit track.
Les pattes sont avantageusement réalisées en un matériau électriquement conducteur, de sorte qu'un circuit électrique fermé peut être formé par l'unité de contrôle, une première patte jouant le rôle d'un conducteur aller, la portion électriquement conductrice rapportée sur le premier capot, la deuxième patte jouant le rôle d'un conducteur retour et à nouveau l'unité de contrôle. Un faible courant, notamment quand du courant circule dans les conducteurs, peut alors circuler dans ce circuit. L'ouverture du premier capot ouvre ce circuit électrique et l'unité de contrôle peut détecter cette ouverture en mesurant un courant nul dans le circuit.  The tabs are advantageously made of an electrically conductive material, so that a closed electrical circuit can be formed by the control unit, a first tab acting as a go conductor, the electrically conductive portion reported on the first cover , the second leg playing the role of a driver back and again the control unit. A weak current, especially when current flows in the conductors, can then flow in this circuit. The opening of the first cover opens this electrical circuit and the control unit can detect this opening by measuring a zero current in the circuit.
La portion rapportée sur le premier capot est notamment rapportée sur la surface intérieure du capot. Les pattes et/ou ladite portion rapportée sur le premier capot peuvent être métalliques ou métallisées.  The portion attached to the first cover is particularly reported on the inner surface of the cover. The tabs and / or said portion attached to the first cover may be metallic or metallized.
La portion électriquement conductrice rapportée sur le premier capot présente par exemple une forme de U et chaque patte peut être disposée de manière à ce que son extrémité libre contacte une branche du U lorsque le premier capot est fermé. Il s'agit par exemple d'une piste en forme de U d'un circuit imprimé.  The electrically conductive portion attached to the first cover has for example a U-shaped and each tab can be arranged so that its free end contacts a branch of the U when the first cover is closed. This is for example a U-shaped track of a printed circuit.
Chaque patte peut présenter une forme coudée. L'unité de contrôle comprend par exemple au moins une unité de traitement numérique, par exemple un micro-contrôleur. L'unité de contrôle peut être montée sur la carte électronique du composant. Each leg may have a bent shape. The control unit comprises for example at least one digital processing unit, for example a microcontroller. The control unit can be mounted on the electronic board of the component.
L'unité de contrôle, les pattes et la portion électriquement conductrice rapportée sur le premier capot peuvent former le système de commande mentionné ci-dessus.  The control unit, the tabs and the electrically conductive portion reported on the first cover can form the control system mentioned above.
L'invention a encore pour objet un procédé d'assemblage du connecteur électrique décrit ci-dessus.  The invention also relates to a method of assembling the electrical connector described above.
L'invention a également pour objet un véhicule automobile, et notamment un véhicule automobile électrique comprenant un connecteur électrique décrit ci-dessus.  The invention also relates to a motor vehicle, and in particular an electric motor vehicle comprising an electrical connector described above.
D'autres aspects facultatifs de l'invention sont mentionnés dans les revendications dépendantes.  Other optional aspects of the invention are mentioned in the dependent claims.

La pièce métallique 4B vient également au contact du boîtier 2 lorsque le capot latéral 4 est fixé sur le boîtier 2.  The side cover 4 further comprises a metal part 4B fixed to the plastic part 4A, for example by screwing or bouterollage. The metal part 4B is in contact with the shielding sheath of the conductors 8, so as to resume the shielding of the conductors 8. The metal part 4B also comes into contact with the housing 2 when the side cover 4 is fixed on the housing 2.
Le capot latéral 4 est fixé sur le boîtier 2 à l'aide d'un moyen démontable, par exemple par vissage ou clipsage. Les cosses 9 sont quant à elles vissées sur la partie métallique du bornier 6 à l'aide de vis 10 via l'ouverture supérieure 5 du boîtier 2.  The side cover 4 is fixed on the housing 2 by means of a removable means, for example by screwing or clipping. The lugs 9 are screwed to the metal part of the terminal block 6 by means of screws 10 via the upper opening 5 of the housing 2.
Le connecteur 1 est fermé en fixant le capot supérieur 3 sur le boîtier 2, également à l'aide d'un moyen démontable, par exemple par vissage ou clipsage. Un joint d'étanchéité peut être disposé entre le capot supérieur 3 et le boîtier 2, de manière à renforcer l'étanchéité du connecteur 1. Le capot supérieur 3 doit en outre fermer le blindage du connecteur 1. Le capot supérieur 3 peut ainsi être en matériau conducteur ou être une pièce en matière plastique munie d'un matériau conducteur. Le blindage électromagnétique ainsi réalisé permet de contenir les forts champs électromagnétiques générés par les conducteurs 8.  The connector 1 is closed by fixing the upper cover 3 on the housing 2, also by means of a removable means, for example by screwing or clipping. A seal may be disposed between the upper cover 3 and the housing 2, so as to reinforce the sealing of the connector 1. The upper cover 3 must further close the shield of the connector 1. The upper cover 3 can thus be in conductive material or be a plastic part provided with a conductive material. The electromagnetic shield thus produced makes it possible to contain the strong electromagnetic fields generated by the conductors 8.
Le connecteur 1 comprend en outre un système de détection de l'ouverture du capot supérieur 3. Si un utilisateur veut déconnecter le connecteur 1 , il doit d'abord enlever le capot supérieur 3 pour dévisser les cosses 9. Le connecteur 1 comprend un système de commande qui coupe le courant lors d'une ouverture du capot supérieur 3, protégeant ainsi l'utilisateur de tout danger d'électrocution. En effet, de forts courants, par exemple jusqu'à plusieurs centaines d'Ampères, couplés ou non à des tensions jusqu'à plusieurs centaines de Volts, sont utilisés dans les véhicules électriques. La détection de l'ouverture du capot supérieur 3 peut par exemple être réalisée à l'aide d'un bouton poussoir, d'un interrupteur, ou d'un connecteur deux voies dont une voie est fixée sur le bornier 6 et l'autre voie sur le capot supérieur 3.  The connector 1 further comprises a detection system of the opening of the top cover 3. If a user wants to disconnect the connector 1, he must first remove the top cover 3 to unscrew the lugs 9. The connector 1 comprises a system which cuts off the current when the top cover 3 is opened, thus protecting the user from any danger of electrocution. Indeed, strong currents, for example up to several hundred amperes, coupled or not with voltages up to several hundred volts, are used in electric vehicles. The detection of the opening of the upper cover 3 may for example be carried out using a push button, a switch, or a two-way connector, one channel is fixed on the terminal block 6 and the other track on the top cover 3.
La figure 2 est un organigramme illustrant une architecture de véhicule automobile électrique. L'architecture comprend un chargeur électrique relié au réseau électrique, une batterie haute tension, un convertisseur, un compresseur de climatisation, un variateur, un calculateur, ainsi qu'un moteur électrique. Figure 2 is a flowchart illustrating an architecture of an electric motor vehicle. The architecture includes an electrical charger connected to the electricity grid, a high voltage battery, a converter, an air conditioning compressor, a dimmer, a computer, and an electric motor.
Le convertisseur est destiné à convertir la haute tension en basse tension pour alimenter une batterie basse tension. Le variateur, également appelé « onduleur » ou « inverter » en langue anglaise, est un moduleur qui transforme le courant continu issu de la batterie haute tension en courant alternatif pour le moteur électrique.  The converter is intended to convert the high voltage low voltage to supply a low voltage battery. The drive, also called "inverter" or "inverter" in English, is a modulator that converts the DC current from the high voltage battery into alternating current for the electric motor.
Le connecteur électrique selon l'invention peut par exemple être utilisé pour connecter le chargeur à la batterie, la batterie au convertisseur, la batterie au compresseur, la batterie au variateur, et le variateur au moteur électrique.  The electrical connector according to the invention can for example be used to connect the charger to the battery, the battery to the converter, the battery to the compressor, the battery to the drive, and the drive to the electric motor.
Dans l'exemple des figures 3 et 4, la détection de l'ouverture du capot supérieur 3 est réalisée à l'aide de pattes 20 s'étendant à travers le boîtier 2. Ces pattes présentent par exemple une première extrémité 21 représentée sur la figure 4 connectée à une carte électronique du composant à connecter aux conducteurs 8. Les pattes 20 ont une extrémité libre 22 située au- delà d'un coude 23 et cette extrémité libre 22 peut être configurée, comme représenté sur les figures 3 et 4, pour venir au contact d'une portion électriquement conductrice 24 rapportée sur la surface intérieure du premier capot 3. Cette portion 24 peut correspondre à une ou plusieurs pistes d'un circuit imprimé reposant par son substrat isolant sur la paroi interne du premier capot 3.  In the example of FIGS. 3 and 4, detection of the opening of the upper cover 3 is carried out by means of lugs 20 extending through the housing 2. These lugs have, for example, a first end 21 shown on FIG. FIG. 4 connected to an electronic card of the component to be connected to the conductors 8. The tabs 20 have a free end 22 situated beyond a bend 23 and this free end 22 can be configured, as represented in FIGS. 3 and 4, to come into contact with an electrically conductive portion 24 attached to the inner surface of the first cover 3. This portion 24 may correspond to one or more tracks of a printed circuit resting by its insulating substrate on the inner wall of the first cover 3.
Une unité de contrôle non représentée peut détecter que le premier capot 3 est fermé en mesurant la valeur non nulle d'un courant électrique parcourant les pattes 20 et la portion 24 rapportée sur le premier capot 3.  An unrepresented control unit can detect that the first cover 3 is closed by measuring the non-zero value of an electric current flowing through the tabs 20 and the portion 24 attached to the first cover 3.
Lorsque le premier capot 3 est ouvert, la valeur du courant mesurée devient nulle et l'ouverture du capot 3 étant détectée, le courant électrique dans le ou les conducteurs 8 peut être interrompu.  When the first cover 3 is open, the value of the measured current becomes zero and the opening of the cover 3 is detected, the electric current in the conductor (s) 8 can be interrupted.
L'invention n'est pas limitée aux exemples qui viennent d'être décrits.  The invention is not limited to the examples which have just been described.
L'expression « comportant un » doit être comprise comme signifiant « comportant au moins un », sauf lorsque le contraire est spécifié.  The expression "comprising a" shall be understood as meaning "containing at least one", except when the opposite is specified.
