Description

L'invention se rapporte à un connecteur électrique pour le raccordement des câbles assurant la connexion électrique de puissance entre deux voitures adjacentes d'un véhicule ferroviaire.The invention relates to an electrical connector for connecting the cables providing the electrical power connection between two adjacent cars of a railway vehicle.

La plupart des véhicules ferroviaires comportent des motrices, par exemple en tête et en queue de véhicule, qui sont alimentées électriquement par une caténaire au moyen d'un pantographe, les autres voitures du véhicule étant alimentées électriquement, de proche en proche, par des câbles de liaisons disposés entre les véhicules. Jusqu'à présent, deux câbles de liaison étaient suffisants pour alimenter une voiture étant donné que ces voitures ne comportaient que des équipements de faible puissance, tels que des dispositifs d'éclairage et de climatisation. Toutefois, il se développe actuellement de nouveaux types de véhicules ferroviaires appelés à motorisation répartie, décrits par exemple dans la demande de brevet FR 2 788 739 , dans lesquels chaque voiture du véhicule ferroviaire comporte un bogie moteur. Pour de tels véhicules, chaque voiture doit être alimentée électriquement avec une puissance importante, afin de permettre le fonctionnement des moteurs de traction. Or, les câbles de liaison étant normalisés, il est nécessaire de multiplier le nombre de câbles de liaison entre véhicules pour répondre aux besoins électriques de chaque voiture, chaque câble ne pouvant laisser passer qu'une puissance limitée. Ainsi, une vingtaine de câbles de liaison entre chaque voiture peuvent être nécessaires pour les véhicules à motorisation répartie. Une telle multiplication des câbles de liaison présente toutefois l'inconvénient de multiplier le nombre de connecteurs disposés dans chaque véhicule pour établir le raccordement entre ces câbles de liaison et un circuit électrique du véhicule. Or, l'espace disponible pour installer ces connecteurs est limité compte tenu de la présence du couloir d'intercirculation entre véhicules.Most railway vehicles have engines, for example at the head and tail of the vehicle, which are electrically powered by a catenary using a pantograph, the other cars of the vehicle being electrically powered, step by step, by cables of links arranged between the vehicles. Until now, two connecting cables were sufficient to power a car since these cars only included low power equipment, such as lighting and air conditioning. However, there is currently developing new types of railway vehicles called distributed motorization, described for example in the patent application. FR 2 788 739 , in which each car of the railway vehicle comprises a motor bogie. For such vehicles, each car must be electrically powered with significant power, to allow the operation of the traction motors. However, the connecting cables are standardized, it is necessary to multiply the number of connecting cables between vehicles to meet the electrical needs of each car, each cable can pass only a limited power. Thus, twenty or so connecting cables between each car may be necessary for vehicles with distributed drive. Such multiplication of the connecting cables however has the disadvantage of multiplying the number of connectors arranged in each vehicle to establish the connection between these connecting cables and an electrical circuit of the vehicle. However, the space available to install these connectors is limited given the presence of the inter-traffic corridor between vehicles.

EP 0 681 343 décrit un autre exemple de connecteur électrique. Dans EP 0 681 343 le connecteur électrique comporte un profil en matériau conducteur qui inclut une partie en forme d'escalier avec chaque marche qui comprend un trou de réception d'un goujon. EP 0 681 343 describes another example of an electrical connector. In EP 0 681 343 the electrical connector includes a profile of conductive material that includes a stair-shaped portion with each step that includes a hole for receiving a stud.

Aussi, le but de la présente invention est de proposer un connecteur électrique pour le raccordement d'un câble assurant la liaison électrique entre deux voitures d'un véhicule ferroviaire qui soit léger, peu encombrant et qui ne nécessite pas d'outils pour le raccordement de la liaison tout en étant simple et économique à réaliser. Un autre but de la présente invention est de proposer un connecteur électrique qui permette le raccordement des câbles de liaison sans risque de mauvais raccordement.Also, the purpose of the present invention is to provide an electrical connector for connecting a cable providing the electrical connection between two cars of a railway vehicle which is light, compact and does not require tools for connection the link while being simple and economical to achieve. A Another object of the present invention is to provide an electrical connector which allows the connection of the connection cables without risk of poor connection.

Pour faciliter la lecture du dessin, seuls les éléments nécessaires à la compréhension de l'invention ont été représentés. Les mêmes éléments portent les mêmes références d'une figure à l'autre.To facilitate the reading of the drawing, only the elements necessary for the understanding of the invention have been represented. The same elements bear the same references from one figure to another.

Les figures 1 à 3 représentent un module de liaison comportant un connecteur destiné à être disposé dans une voiture de véhicule ferroviaire, préférentiellement à proximité d'une extrémité longitudinale de la voiture. Ce module de liaison est destiné à permettre le raccordement d'un circuit électrique 6 de la voiture avec un câble 2 assurant la liaison électrique vers une seconde voiture du véhicule ferroviaire.The Figures 1 to 3 represent a connection module comprising a connector intended to be arranged in a rail vehicle car, preferably near a longitudinal end of the car. This link module is intended to enable connecting an electrical circuit 6 of the car with a cable 2 providing the electrical connection to a second car of the railway vehicle.

Conformément à ces figures, le connecteur 1 comporte un socle 3 en matériau électriquement isolant, tel que du Latamid, comprenant deux parois latérales s'élevant de part et d'autre d'une zone centrale en forme d'escalier. La zone centrale comprend deux marches sur lesquelles repose un profil 4 en matériau électriquement conducteur, tel que du cuivre, ce profil 4 comportant une partie 4a en forme d'escalier épousant localement les marches de la zone centrale et se prolongeant à l'extérieur du socle 3 par une partie rectiligne 4b s'étendant suivant une direction sensiblement perpendiculaire à face inférieure du socle 3, la direction d'extension de la partie rectiligne 4b étant fonction de l'environnement des connexions.According to these figures, the connector 1 comprises a base 3 of electrically insulating material, such as latamid, comprising two side walls rising on either side of a central zone in the form of a staircase. The central zone comprises two steps on which rests a profile 4 made of electrically conductive material, such as copper, this profile 4 comprising a stair-shaped part 4a locally matching the steps of the central zone and extending outside the base 3 by a straight portion 4b extending in a direction substantially perpendicular to the lower face of the base 3, the extension direction of the straight portion 4b is a function of the environment of the connections.

Conformément à la figure 3, le profil 4 présente, au niveau de chaque marche, un trou permettant le passage d'un goujon 5 porté par le socle 3, ce goujon 5 étant destiné à permettre la connexion électrique d'un câble 6 appartenant au circuit électrique du véhicule à raccorder. Le câble 6 comporte une extrémité munie d'une cosse 6a qui est prise en sandwich entre le profil 4 et un écrou de serrage 7 rapporté sur le goujon 5.In accordance with the figure 3 , the profile 4 has, at each step, a hole allowing the passage of a stud 5 carried by the base 3, this stud 5 being intended to allow the electrical connection of a cable 6 belonging to the electric circuit of the vehicle to connected. The cable 6 has an end provided with a lug 6a which is sandwiched between the profile 4 and a clamping nut 7 attached to the stud 5.

La partie rectiligne 4b du profil 4 comporte deux douilles 8 en matériau électriquement conducteur, par exemple en cuivre, ces douilles 8 étant alignées l'une au-dessus de l'autre sur l'axe longitudinal du profil 4. Les douilles 8 sont en contact électrique avec le profil 4, en étant par exemple soudées dans une ouverture du profil 4, et sont adaptées pour recevoir des broches 9 de connexion disposées à une extrémité du câble de liaison 2 assurant la liaison électrique entre les deux voitures du véhicule, les douilles 8 et les broches 9 pouvant être de différentes tailles. De manière connue, l'intérieur des douilles 8 comporte un contact à lamelles, non représenté sur les figures, permettant d'assurer un bon contact électrique entre la broche 9 et la douille 8 lorsque la broche 9 est insérée dans cette dernière.The rectilinear portion 4b of the profile 4 comprises two sockets 8 of electrically conductive material, for example copper, these sockets 8 being aligned one above the other on the longitudinal axis of the profile 4. The sockets 8 are in electrical contact with the profile 4, being for example welded in an opening of the profile 4, and are adapted to receive connecting pins 9 arranged at one end of the connecting cable 2 providing the electrical connection between the two cars of the vehicle, the sockets 8 and pins 9 can be of different sizes. In known manner, the inside of the sleeves 8 comprises a lamellar contact, not shown in the figures, to ensure a good electrical contact between the pin 9 and the sleeve 8 when the pin 9 is inserted in the latter.

Selon un mode de réalisation préférentiel de l'invention, chaque douille 8 est équipée d'une première bague 10 de détrompage qui est insérée à l'intérieur de la douille 8 et chaque broche 9 comporte une seconde bague 11 de détrompage qui est rapportée autour de la broche 9 de connexion. Les première et seconde bagues 10, 11 possèdent des formes adaptées afin que seules les broches 9 munies d'une seconde bague 11 de forme complémentaire de la première bague I 0 présente dans la douille 8 puisse être insérées complètement dans la douille 8. Un tel mode de réalisation permet d'éviter des erreurs de branchements lors des raccordements en aveugle des câbles de liaison 2 avec le connecteur I.According to a preferred embodiment of the invention, each bushing 8 is equipped with a first keying ring 10 which is inserted inside the bushing 8 and each pin 9 comprises a second keying ring 11 which is inserted around it pin 9 connection. The first and second rings 10, 11 have shapes adapted so that only the pins 9 provided with a second ring 11 of complementary shape of the first ring I 0 present in the sleeve 8 can be inserted completely into the sleeve 8. Such embodiment avoids connection errors during blind connections of connection cables 2 with connector I.

La figure 4 représente isolément un exemple de couple de bagues de détrompage 10, 11. Conformément à cette figure, les bagues 10, 11 comportent chacune un bord latéral comprenant un ergot 10a, 11 a venant pénétrer dans une encoche I0b, 11 b du bord latéral de l'autre bague lorsque les bagues 10, 11 sont rapprochées l'une de l'autre, l'emplacement des ergots 10a, 11a et des encoches 10b, 11 b sur les bagues étant spécifique à chaque module de liaison. De manière avantageuse, les bagues de détrompage 10, 11 associées possèdent une couleur propre permettant de les distinguer des autres couples de bagues.The figure 4 is an example of a pair of keying rings 10, 11. In accordance with this figure, the rings 10, 11 each comprise a lateral edge comprising a lug 10a, 11a to penetrate a notch I0b, 11b of the lateral edge of the Another ring when the rings 10, 11 are brought closer to each other, the location of the lugs 10a, 11a and notches 10b, 11b on the rings being specific to each link module. Advantageously, the keying rings 10, 11 associated have a clean color to distinguish them from other pairs of rings.

Conformément aux figures 1 et 2, chaque broche 9 est pourvue d'une rainure 9a qui vient en regard d'une fente 8a réalisée sur le corps de la douille 8 et qui reçoit, lorsque la broche 9 est insérée à fond dans la douille 8, un clip de verrouillage 12 sécurisé par une agrafe, ce clip 12 permettant d'empêcher toute déconnexion involontaire de la broche 9.In accordance with Figures 1 and 2 each pin 9 is provided with a groove 9a which faces a slot 8a formed on the body of the sleeve 8 and which receives, when the pin 9 is fully inserted in the sleeve 8, a locking clip 12 secure by a clip, this clip 12 to prevent inadvertent disconnection of the pin 9.

Les faces extérieures des parois latérales du socle du connecteur comportent des rainures 3a formant mortaise et des protubérances 3b en forme de queue d'aronde adaptées pour permettre l'assemblage du socle 3 avec un ou plusieurs autres socles 3 identiques. Un tel assemblage est représenté sur la figure 5 où l'on peut voir quatre connecteurs 1, identiques à celui des figures 1 à 3, assemblés les uns aux autres, ces quatre connecteurs 1 étant également assemblés à deux autres connecteurs 21 réalisés selon un autre mode de réalisation de l'invention, ces deux connecteurs 21 comportant un socle 3 identique à celui des figures 1 à 3 mais comportant un profil muni d'une seule douille.The outer faces of the side walls of the base of the connector comprise grooves 3a forming a mortise and dovetail shaped protuberances 3b adapted to allow the assembly of the base 3 with one or more other bases 3 identical. Such an assembly is represented on the figure 5 where we can see four connectors 1, identical to that of Figures 1 to 3 , these four connectors 1 being also assembled to two other connectors 21 made according to another embodiment of the invention, these two connectors 21 comprising a base 3 identical to that of the Figures 1 to 3 but having a profile with a single socket.

Le connecteur selon l'invention présente ainsi l'avantage de permettre un grand nombre de connexion dans un ensemble compact. De plus, la superposition de deux douilles sur un même profil permet le branchement de deux câbles de liaison en parallèle, ce qui permet, en conservant des câbles de liaison normalisés, de doubler la puissance distribuable par le connecteur sans augmenter l'encombrement latéral de ce dernier.The connector according to the invention thus has the advantage of allowing a large number of connections in a compact assembly. In addition, the superposition of two sockets on the same profile allows the connection of two connecting cables in parallel, which allows, while maintaining standardized connecting cables, to double the distributable power by the connector without increasing the lateral dimensions of this last.

Le connecteur selon l'invention est donc particulièrement adapté pour le raccordement des câbles de liaison assurant la liaison électrique entre deux voitures d'un véhicule ferroviaire équipé d'une motorisation répartie, c'est à dire lorsque chaque voiture du véhicule comporte un bogie muni d'un moteur de traction.The connector according to the invention is therefore particularly suitable for connecting the connecting cables providing the electrical connection between two cars of a railway vehicle equipped with a distributed engine, that is to say when each car of the vehicle comprises a bogie equipped with a traction motor.

Enfin, la présence de bague des détrompage dans un tel connecteur permet d'éviter des mauvais raccordements des câbles de liaison lorsque plusieurs connecteurs sont associés les uns aux autres. Cet avantage est particulièrement important pour éviter les inversions de phase lorsque les câbles de liaison servent à alimenter une voiture en courant triphasé ou des équipements individuels tels que moteurs ou blocs d'appareillage de puissance, à chaque connecteur étant alors associé une phase particulière correspondant à un couple de bague de détrompage.Finally, the presence of polarizing ring in such a connector makes it possible to avoid mis-connections of the connecting cables when several connectors are associated with each other. This advantage is particularly important to avoid phase reversals when the connecting cables are used to power a car with three-phase power or individual equipment such as motors or power equipment blocks, each connector being associated with a particular phase corresponding to a pair of foolproof ring.

Bien entendu, l'invention n'est nullement limitée au mode de réalisation décrit et illustré qui n'a été donné qu'à titre d'exemple. Des modifications restent possibles, notamment du point de vue de la constitution des divers éléments ou par substitution d'équivalents techniques, sans sortir pour autant du domaine de protection de l'invention.Of course, the invention is not limited to the embodiment described and illustrated which has been given by way of example. Modifications are possible, particularly from the point of view of the constitution of the various elements or by substitution of technical equivalents, without departing from the scope of protection of the invention.
