Description

Le domaine technique de l'invention est celui des dispositifs assurant l'alimentation électrique de différents équipements et en particulier des dispositifs d'alimentation destinés à équiper un véhicule, tel un véhicule de combat.The technical field of the invention is that of devices providing power to various equipment and in particular power devices intended to equip a vehicle, such as a combat vehicle.

Il est connu de réaliser des réseaux assurant l'alimentation électrique de différents équipements à partir d'une ou plusieurs sources d'énergie.It is known to provide networks ensuring the power supply of different equipment from one or more sources of energy.

La plupart du temps l'alimentation est effectuée par un ou plusieurs réseaux structurés en étoile entre le générateur et les différents équipements.Most of the time, power is supplied by one or more star-shaped networks between the generator and the different equipment.

Cependant une telle solution met en oeuvre des longueurs de câbles importantes et elle est donc difficile à intégrer.However, such a solution implements long cable lengths and is therefore difficult to integrate.

Il est connu également de réaliser un réseau électrique sous la forme d'un bus annulaire. La demande de brevet US6552443 décrit un tel type de réseau qui présente comme avantage de réduire le nombre de câbles mis en oeuvre et qui permet aussi d'autoriser l'alimentation par l'un ou l'autre des côtés du bus en cas de coupure accidentelle.It is also known to provide an electrical network in the form of an annular bus. The patent application US6552443 discloses such a type of network which has the advantage of reducing the number of cables used and also allows to allow power from one or the other side of the bus in case of accidental cut.

Ce bus annulaire incorpore des noeuds au niveau desquels sont raccordés les équipements. Chaque noeud est susceptible d'assurer la coupure du Bus afin d'isoler un segment du bus en cas d'incident (donc également le ou les équipements raccordés au niveau du noeud).This annular bus incorporates nodes at which the equipment is connected. Each node is capable of breaking the bus in order to isolate a segment of the bus in the event of an incident (thus also the equipment connected to the node).

Cette configuration est complexe car elle met en oeuvre des noeuds dont le positionnement est figé lors de la conception du réseau. Il n'est donc pas possible de faire évoluer ultérieurement le réseau sauf à le couper pour incorporer de nouveaux noeuds.This configuration is complex because it implements nodes whose positioning is fixed during the design of the network. It is therefore not possible to upgrade the network later except cut it to incorporate new nodes.

Par ailleurs cette configuration ne vise que la réalisation du bus annulaire de puissance et ne règle pas le problème de la réalisation des bus de commande / contrôle qui permettent d'assurer la commande des différents noeuds et les échanges d'informations dans le véhicule.Furthermore, this configuration is aimed only at the realization of the annular power bus and does not solve the problem of the realization of the command / control buses which make it possible to ensure the control of the different nodes and the exchange of information in the vehicle.

On connaît également par le brevet EP-993994-A - un moyen de câblage comprenant de fines feuilles conductrices noyées dans un matériau isolant, selon le préambule de la revendication 1.It is also known from the patent EP-993994-A wiring means comprising thin conductive sheets embedded in an insulating material, according to the preamble of claim 1.

Afin de permettre son raccordement, ce moyen incorpore plusieurs branches conductrices souples qui sont reliées chacune à une feuille conductrice. Ces branches permettent de raccorder des connecteurs externes au moyen de câblage.In order to allow its connection, this means incorporates several flexible conductive branches which are connected each to a conductive sheet. These branches make it possible to connect external connectors by means of wiring.

Ce moyen présente lui aussi des inconvénients. Il est ainsi difficile pour un utilisateur de mettre en place de nouveaux équipements et/ou raccordements avec un tel moyen de câblage. Les branches de raccordement doivent en effet être définies lors de la conception du câblage et elles sont fabriquées et insérées une fois pour toute lors de la fabrication.This means also has disadvantages. It is thus difficult for a user to set up new equipment and / or connections with such a means of wiring. The connecting legs must indeed be defined during the design of the wiring and they are manufactured and inserted once and for all during manufacture.

Par ailleurs le fait de prévoir les raccordements sortant tous du moyen de câblage au niveau de son épaisseur augmente l'encombrement du moyen de câblage et pose des problèmes d'isolement. On notera enfin que ce moyen de câblage souple ne peut véhiculer des courants de forte intensité (supérieure à 50 Ampères) et qu'il est donc inadapté pour réaliser des circuits de puissance.Moreover, the fact of providing the connections all out of the wiring means at its thickness increases the size of the wiring means and poses insulation problems. Finally, note that this flexible wiring means can not convey currents of high intensity (greater than 50 amps) and is therefore unsuitable for producing power circuits.

L'invention a pour but de proposer un dispositif d'alimentation électrique simplifié qui permet de réduire la masse et le volume des câbles et des organes de couplage et de protection.The invention aims to provide a simplified power supply device that reduces the mass and volume of cables and coupling and protection members.

Le dispositif selon l'invention permet également de reconfigurer automatiquement l'alimentation électrique en cas de défaillance ou destruction partielle du réseau.The device according to the invention also makes it possible to automatically reconfigure the power supply in the event of failure or partial destruction of the network.

Le dispositif selon l'invention permet enfin de faciliter la mise en place de nouveaux équipements et/ou raccordements sans refondre totalement le câblage.The device according to the invention finally makes it easier to set up new equipment and / or connections without totally overhauling the wiring.

L'invention a ainsi pour objet un dispositif d'alimentation électrique, en particulier pour un véhicule, et comportant au moins un réseau de conducteurs, dispositif caractérisé en ce que le réseau comprend au moins une barre bus formée d'un socle comportant un logement longitudinal à l'intérieur duquel est disposé un matériau isolant qui renferme des conducteurs, conducteurs portant des surfaces de contact non isolées qui sont disposées affleurantes au niveau d'une face de la barre au niveau de laquelle se trouve le matériau isolant, surfaces de contact qui sont entourées par le matériau isolant et qui sont destinées à coopérer avec au moins un connecteur.The invention thus relates to a power supply device, in particular for a vehicle, and comprising at least one network of conductors, characterized in that the network comprises at least one bus bar formed of a base comprising a housing longitudinal axis inside which is disposed an insulating material which encloses conductive conductors carrying uninsulated contact surfaces which are arranged flush at a face of the bar at which the insulating material is located, contact surfaces which are surrounded by the insulating material and which are intended to cooperate with at least one connector.

Le dispositif pourra comprendre au moins deux barres bus reliées l'une à l'autre par des moyens de liaison électrique.The device may comprise at least two bus bars connected to each other by electrical connection means.

Les moyens de liaison électrique pourront comprendre au moins un câble souple portant à chaque extrémité un connecteur adaptable à une barre bus.The electrical connection means may comprise at least one flexible cable carrying at each end a connector adaptable to a bus bar.

La ou les barres bus pourront comporter au moins un circuit de puissance comportant au moins une barre conductrice portant une surface de contact non isolée.The at least one busbar may comprise at least one power circuit comprising at least one conducting bar carrying an uninsulated contact surface.

La ou les barres bus pourront comporter au moins deux barres conductrices portant chacune une surface de contact non isolée.The busbar or busbars may comprise at least two busbars each carrying an uninsulated contact surface.

La ou les barres bus pourront comporter au moins un circuit de commande/contrôle comportant au moins deux conducteurs.The busbar (s) may comprise at least one control / control circuit comprising at least two conductors.

Avantageusement, chaque barre bus pourra comporter plusieurs emplacements contigus, chaque emplacement pouvant recevoir un connecteur distinct, chaque emplacement comportant par ailleurs une surface de contact non isolée reliée au circuit de puissance.Advantageously, each busbar may have several contiguous locations, each location being able to receive a separate connector, each location also comprising an uninsulated contact surface connected to the power circuit.

Chaque emplacement de la barre bus pourra également comporter deux paires de contacts reliés à un circuit de commande / contrôle.Each location of the busbar may also include two pairs of contacts connected to a control / control circuit.

Au moins un connecteur pourra comporter des moyens coopérant avec les contacts du circuit de commande / contrôle.At least one connector may comprise means cooperating with the contacts of the control / control circuit.

Au moins un connecteur pourra par ailleurs comporter un moyen de coupure permettant d'interrompre le passage du courant de puissance au travers du connecteur, moyen de coupure qui sera commandé au travers du circuit de commande / contrôle.At least one connector may also include a cutoff means for interrupting the passage of power through the connector, cutoff means that will be controlled through the control / control circuit.

L'invention a également pour objet un connecteur qui est destiné à être raccordé à une barre bus d'un dispositif d'alimentation électrique selon l'invention, ce connecteur ayant au moins un contact destiné à être appliqué par un moyen de précontrainte contre une surface de contact non isolée solidaire d'une face de la barre bus.The invention also relates to a connector which is intended to be connected to a bus bar of a power supply device according to the invention, this connector having at least one contact intended to be applied by a prestressing means against a uninsulated contact surface integral with one face of the bus bar.

Le connecteur pourra incorporer un moyen de coupure permettant d'interrompre le passage du courant de puissance au travers du connecteur.The connector may incorporate a cut-off means for interrupting the passage of the power current through the connector.

Le connecteur pourra comporter au moins une prise spécifique destinée à être raccordée à des contacts d'un circuit de commande / contrôle.The connector may comprise at least one specific socket intended to be connected to contacts of a control / control circuit.

Connecteurs qui incorporent eux aussi un moyen de coupure et de protection électrique S1, S2, S3 ... S12.Each generator G1 ... G6 and each member R1 ... R6 is connected at one of the branches BR1 ... BR6 via connectors (not shown in this figure). Connectors which also incorporate an electrical breaking and protection means S1, S2, S3 ... S12.

Par ailleurs le bus bifilaire 3 de contrôle / commande est relié à au moins deux moyens 5 de gestion des échanges qui assurent le pilotage des différents moyens de protection et de coupure S1...S12 et K1...K6.Furthermore, the two-wire control / command bus is connected to at least two exchange management means 5 which control the different protection and cutoff means S1 ... S12 and K1 ... K6.

D'une façon connue, les moyens de gestion 5 assurent la surveillance des courants circulant dans le conducteur de puissance 2, dans les liaisons vers les organes R ainsi que les tensions et températures relevées en divers points du réseau. Ces courants sont mesurés dans les moyens de coupure et de protection électriques.In a known manner, the management means 5 monitor the currents flowing in the power conductor 2, in the links to the organs R as well as the voltages and temperatures recorded at various points of the network. These currents are measured in the electrical breaking and protection means.

En fonction des mesures effectuées, les moyens 5 déterminent quel organe R est défaillant ou bien quelle branche BR est globalement défaillante et ils commandent l'ouverture des moyens de coupure appropriés permettant d'isoler l'organe ou la branche défaillante du reste du réseau.Depending on the measurements made, the means 5 determine which member R is faulty or which Branch BR is generally faulty and they control the opening of the appropriate breaking means for isolating the organ or the failing branch of the rest of the network.

La commande et l'adressage sont réalisés en mettant en oeuvre les protocoles classiques de commande par Bus numérique (par exemple un protocole du type CAN basse vitesse).The control and the addressing are carried out by implementing the conventional digital bus control protocols (for example a low speed CAN type protocol).

La reconfiguration du Bus de commande / contrôle 3 en cas de coupure du réseau annulaire ne fait pas l'objet de la présente invention. On pourra mettre en oeuvre la commande d'interrupteurs (non représentés sur les figures) et spécifiques à la ligne bus, interrupteurs permettant d'isoler une branche défaillante et également de déplacer les résistances de terminaison. On pourra par exemple considérer le brevet EP-895899 qui décrit un tel type de moyen de reconfiguration.The reconfiguration of the control / control bus 3 in the event of a break in the ring network is not the subject of the present invention. It will be possible to implement the control of switches (not shown in the figures) and specific to the bus line, switches for isolating a faulty branch and also to move the termination resistors. For example, one could consider the patent EP-895 899 which describes such a type of reconfiguration means.

Conformément à une autre caractéristique de l'invention, chaque branche BR comprend au moins une barre bus comportant des conducteurs solidaires d'un support isolant.According to another characteristic of the invention, each branch BR comprises at least one bus bar comprising conductors secured to an insulating support.

Les figures 2a et 2b montrent un exemple de réalisation d'une telle barre bus 6.The Figures 2a and 2b show an embodiment of such a bus bar 6.

Elle comprend un socle conducteur 7 qui comporte un logement parallélépipédique longitudinal 8 à l'intérieur duquel est disposé un matériau isolant 9 qui renferme différents conducteurs 10, 11, 12.It comprises a conductive base 7 which comprises a longitudinal parallelepipedal housing 8 inside which is disposed an insulating material 9 which encloses different conductors 10, 11, 12.

Le socle 7 porte des taraudages 19 qui permettent la fixation de connecteurs 4 (4a,4b) comme cela sera décrit par la suite. Il est bien entendu possible de prévoir d'autres modes de fixation, en particulier un dispositif de fixation rapide permettant le montage et le démontage du connecteur sans outil.The base 7 carries tappings 19 which allow the attachment of connectors 4 (4a, 4b) as will be described later. It is of course possible to provide other modes of attachment, particularly a quick fastener for mounting and disassembly of the connector without tools.

Les conducteurs pourront être réalisés sous la forme de barres (par exemple à section parallélépipédique) dont l'épaisseur dépendra de l'intensité du courant qui doit les traverser.The conductors may be made in the form of bars (for example parallelepipedic section) whose thickness will depend on the intensity of the current that must cross them.

On a représenté ici une barre 10 qui constitue une partie du conducteur de puissance 2. Le retour de courant de puissance sera assuré par le socle conducteur 7 lui-même qui sera fixé au véhicule et en contact électrique avec la masse du véhicule.There is shown here a bar 10 which constitutes a part of the power conductor 2. The power current feedback will be provided by the conductive base 7 itself which will be attached to the vehicle and in electrical contact with the vehicle mass.

Il serait bien entendu possible de prévoir deux ou plusieurs (dans le cas d'un réseau alternatif triphasé par exemple) conducteurs de puissance différents noyés dans le matériau isolant 9. Un mode de réalisation comportant plusieurs conducteurs de puissance sera décrit par la suite en référence aux figures 6a et 6b.It would of course be possible to provide two or more (in the case of a three-phase alternating network for example) different power conductors embedded in the insulating material 9. An embodiment comprising several power conductors will be described later with reference to the Figures 6a and 6b .

Les barres 11 et 12 constituent la ligne bifilaire 3 du circuit de contrôle / commande.The bars 11 and 12 constitute the two-wire line 3 of the control / command circuit.

Le conducteur 10 porte au moins une surface de contact 13, non isolée et affleurante au niveau d'une face 6a de la barre 6. Cette surface de contact est portée ici par un plot 14 qui est soudé à la barre 10 et entouré par le matériau isolant 9. La face 6a de la barre bus 6 est la seule face de cette dernière au niveau de laquelle le matériau isolant 9 est accessible. Elle autorise le passage des surfaces de contact permettant un raccordement aux barres conductrices 10, 11, 12 tout en assurant leur isolement électrique relatif. Tous les raccordements pourront donc être assurés au niveau de cette face 6a qui est facilement accessible.The conductor 10 carries at least one contact surface 13, uninsulated and flush at a face 6a of the bar 6. This contact surface is carried here by a stud 14 which is welded to the bar 10 and surrounded by the insulating material 9. The face 6a of the bus bar 6 is the only face of the latter at which the insulating material 9 is accessible. It allows the passage of the contact surfaces for connection to the busbars 10, 11, 12 while ensuring their relative electrical isolation. All connections can be assured at this face 6a which is easily accessible.

Par ailleurs les barres 11 et 12 sont chacune reliées à au moins une douille de contact 15a ou 15b par des liaisons filaires qui sont noyées dans le matériau isolant.Moreover, the bars 11 and 12 are each connected to at least one contact bushing 15a or 15b by wire links which are embedded in the insulating material.

Les douilles de contact 15a, 15b sont affleurantes au niveau de la face 6a et sont destinées à recevoir un connecteur approprié.The contact sockets 15a, 15b are flush at the face 6a and are intended to receive a suitable connector.

Ainsi les différents conducteurs 10, 11 et 12 se trouvent tous protégés par le socle 7 et sont tous noyés dans le matériau isolant 9 qui est lui-même maintenu et protégé par le logement 8. Le matériau 9 assure l'isolation électrique de tous les conducteurs 10, 11, 12 par rapport au socle 7.Thus the various conductors 10, 11 and 12 are all protected by the base 7 and are all embedded in the insulating material 9 which is itself maintained and protected by the housing 8. The material 9 ensures the electrical insulation of all the conductors 10, 11, 12 with respect to the base 7.

Les conducteurs 10, 11, 12 ne sont donc accessibles qu'au niveau de la face 6a, soit par des surfaces de contact non isolées 13, soit par des douilles de contact 15a, 15b.The conductors 10, 11, 12 are therefore accessible only at the face 6a, either by uninsulated contact surfaces 13 or by contact bushes 15a, 15b.

Il en résulte une organisation compacte de la barre bus 6 qui protège tant les conducteurs que les contacts permettant d'accéder aux conducteurs. Cette configuration autorise différentes connexions possibles et une reconfiguration aisée du réseau sans modification de la barre bus.The result is a compact organization of the bus bar 6 which protects both drivers and contacts to access drivers. This configuration allows different possible connections and easy reconfiguration of the network without changing the busbar.

Comme cela est plus particulièrement visible sur la figure 2a, la barre 6 comporte ainsi plusieurs emplacements 16 tous identiques comprenant chacun une surface de contact 13 et quatre douilles de contact 15a,15b. Les emplacements pourront être matériellement séparés les uns des autres par des surfaces de butées 17 (usinées ou collées sur la barre).As this is particularly visible on the figure 2a , the bar 6 thus comprises several locations 16 all identical, each comprising a contact surface 13 and four contact sleeves 15a, 15b. The locations may be physically separated from each other by abutment surfaces 17 (machined or glued on the bar).

Chaque emplacement peut recevoir un connecteur approprié qui comportera d'une part des moyens assurant un raccordement au circuit de puissance 2 (via une surface de contact 13 et le socle conducteur 7) et d'autre part des moyens de raccordement aux douilles de contact 15a, 15b.Each slot can receive a suitable connector which will comprise on the one hand means providing a connection to the power circuit 2 (via a contact surface 13 and the conductive base 7) and secondly means for connecting the contact sockets 15a. , 15b.

Chaque emplacement comporte deux paires de douilles 15a,15b. En effet lorsqu'un organe R (ou un générateur G) est raccordé à la barre 6, il constitue également un noeud du réseau de commande / contrôle 3 piloté par le Bus de données.Each slot has two pairs of sockets 15a, 15b. Indeed, when an organ R (or a generator G) is connected to the bar 6, it also constitutes a node of the control / control network 3 driven by the data bus.

Il est donc nécessaire de prévoir une connexion en amont du noeud et une connexion en aval du noeud. Des moyens incorporés au connecteur 4a gèreront les contacts ou terminaisons de lignes nécessaires en fonction de l'état défaillant ou non du composant raccordé. De tels moyens sont décrits par exemple par le brevet EP-0895899 déjà cité.It is therefore necessary to provide a connection upstream of the node and a connection downstream of the node. Means incorporated in the connector 4a will manage the contacts or line terminations necessary depending on the state of the connected component or not. Such means are described for example by the patent EP-0895899 already cited.

La largeur de l'emplacement de base 16 est un standard adopté à la conception du dispositif. En fonction des courants à distribuer ou du nombre d'équipements à relier à partir d'un connecteur, un connecteur pourra recouvrir un ou deux emplacements 16.The width of the base location 16 is a standard adopted in the design of the device. Depending on the currents to be distributed or the number of devices to be connected from a connector, a connector may cover one or two locations 16.

La figure 4 montre un connecteur 4a selon l'invention qui est fixé au niveau d'un des emplacements 16 d'une barre bus 6 et qui est relié par un câble souple 23 à un organe R, ou à un générateur G ou à une autre barre Bus (éléments non représentés).The figure 4 shows a connector 4a according to the invention which is fixed at one of the locations 16 of a bus bar 6 and which is connected by a flexible cable 23 to a member R, or to a generator G or to another bus bar (elements not shown).

Des vis 18 assurent la solidarisation du connecteur 4a et de la barre bus 6 au niveau des taraudages 19.Screws 18 secure the connector 4a and the busbar 6 to the threads 19.

La figure 3 montre ce connecteur 4a en coupe partielle.The figure 3 shows this connector 4a in partial section.

Il comporte un boîtier 20 renfermant un moyen de coupure 21 qui permet d'interrompre le passage du courant de puissance au travers du connecteur 4a. Ce moyen de coupure est un circuit électronique comportant par exemple des relais statiques et leurs moyens de commande. Les moyens de commande des relais statiques sont pilotés au travers du circuit de commande / contrôle 3.It comprises a housing 20 enclosing a breaking means 21 which makes it possible to interrupt the passage of the power current through the connector 4a. This breaking means is an electronic circuit comprising for example static relays and their control means. The control means of the solid state relays are controlled via the control / control circuit 3.

Ainsi le moyen de coupure 21 est relié par des prises 25 spécifiques qui coopèrent avec les douilles 15a, 15b.Thus the cut-off means 21 is connected by specific taps which cooperate with the bushes 15a, 15b.

Il est par ailleurs relié par un contact 22 à la surface de contact 13. Le contact 22 est appliqué par un moyen de précontrainte (ici un ressort 24) contre la surface de contact non isolée 13.It is also connected by a contact 22 to the contact surface 13. The contact 22 is applied by a prestressing means (here a spring 24) against the non-insulated contact surface 13.

Un exemple de moyen de coupure 21 envisageable est décrit par le brevet FR2725557 .An example of a possible cutting means 21 is described by the patent FR2725557 .

Le connecteur 4b n'a pas été représenté en détails sur les figures. Il est analogue au connecteur 4a mais dépourvu de moyen de coupure 21. Il pourra cependant incorporer un circuit électronique de gestion du noeud de contrôle / commande associé à l'organe raccordé par ce connecteur. Il comportera alors lui aussi des prises 25 raccordant ce circuit au bus bifilaire 3.The connector 4b has not been shown in detail in the figures. It is similar to the connector 4a but devoid of cut-off means 21. It may, however, incorporate an electronic management circuit of the control node / control associated with the member connected by this connector. It will then also include sockets 25 connecting this circuit to the two-wire bus 3.

On voit que grâce à l'invention il est très facile de raccorder un élément au circuit de distribution. En effet le connecteur 4a incorpore les moyens de coupure et lorsqu'il est fixé à la barre bus 6 il est raccordé à la fois au circuit de puissance 2 via les contacts 22 et 14 et au circuit 3 de contrôle / commande via les prises 25 et les douilles 15a, 15b.We see that thanks to the invention it is very easy to connect an element to the distribution circuit. Indeed, the connector 4a incorporates the breaking means and when it is fixed to the busbar 6 it is connected both to the power circuit 2 via the contacts 22 and 14 and to the control / control circuit 3 via the sockets 25. and the sockets 15a, 15b.

Par ailleurs il est très facile de réaliser un circuit pouvant être coupé et fonctionner en mode dégradé. En effet, il suffit de subdiviser le circuit en plusieurs branches BR formées chacune par une barre bus 6 et de raccorder les branches entre elles par des câbles souples C portant à chaque extrémité un connecteur 4 (4a ou 4b) adaptable à la barre bus. Au moins un des connecteurs (4a) portera un moyen de coupure et permettra d'assurer l'isolation de la branche considérée du reste du circuit en cas de coupure accidentelle.Moreover it is very easy to realize a circuit that can be cut and operate in degraded mode. Indeed, it suffices to subdivide the circuit into several branches BR each formed by a bus bar 6 and to connect the branches together by flexible cables C carrying at each end a connector 4 (4a or 4b) adaptable to the bus bar. At least one of the connectors (4a) will carry a breaking means and will ensure the insulation of the branch considered the rest of the circuit in case of accidental cut.

On pourra avantageusement prévoir un moyen de coupure au niveau de chaque connecteur 4 du câble souple ce qui permettra d'isoler une barre bus 6 de l'ensemble du circuit 1. Cette barre, si elle comporte une source d'énergie G, pourra alors constituer un réseau local entièrement autonome, assurant ainsi un fonctionnement en mode dégradé d'une partie du réseau en cas de défaillance grave.It is advantageous to provide a cut-off means at each connector 4 of the flexible cable, which will make it possible to isolate a bus bar 6 from the entire circuit 1. This bar, if it comprises a source of energy G, may then be constitute a fully autonomous local network, thus ensuring degraded operation of part of the network in the event of a serious failure.

A titre d'exemple la figure 5 montre schématiquement un dispositif d'alimentation comportant deux barres bus 6 reliées l'une à l'autre par des câbles 23 portant à chaque extrémité un connecteur 4a ou 4b. Les dimensions relatives des différents éléments ne sont pas respectées sur ce schéma et ainsi chaque équipement R1 à R6 et R9 à R14 est raccordé à la barre bus par un connecteur de type 4a incorporant un moyen de coupure.For example, figure 5 Diagrammatically shows a supply device comprising two bus bars 6 connected to each other by cables 23 carrying at each end a connector 4a or 4b. The relative dimensions of the different elements are not respected in this diagram and thus each equipment R1 to R6 and R9 to R14 is connected to the bus bar by a connector of type 4a incorporating a breaking means.

A titre de variante il est bien entendu possible de mettre en oeuvre l'invention pour réaliser des réseaux d'alimentation en étoile ou associant un réseau en étoile et un réseau annulaire.As a variant it is of course possible to implement the invention for producing star power supply networks or associating a star network and an annular network.

Les figures 6a et 6b montrent un autre mode de réalisation d'une barre bus 6 comportant plusieurs conducteurs de puissance.The Figures 6a and 6b show another embodiment of a bus bar 6 having a plurality of power conductors.

Comme dans le mode de réalisation précédent, cette barre 6 comprend un socle conducteur 7 qui comporte un logement parallélépipédique longitudinal 8 à l'intérieur duquel est disposé le matériau isolant 9 qui renferme les différents conducteurs : deux conducteurs de puissance 10a, 10b et deux conducteurs de commande 11, 12.As in the previous embodiment, this bar 6 comprises a conductive base 7 which comprises a longitudinal parallelepipedal housing 8 inside which is disposed the insulating material 9 which encloses the different conductors: two power conductors 10a, 10b and two conductors 11, 12.

A titre d'exemple, le socle 7 porte toujours ici des taraudages 19 qui permettent la fixation de connecteurs. D'autres modes de fixation seraient bien entendu possibles.For example, the base 7 still carries here threads 19 which allow the attachment of connectors. Other modes of attachment would of course be possible.

Avec ce mode de réalisation comportant deux conducteurs de puissance le retour du courant de puissance peut être assuré par l'un des deux conducteurs 10a, 10b. Le socle conducteur 7 peut alors être isolé électriquement du circuit de puissance. Le socle 7 pourrait par ailleurs être réalisé en un matériau isolant, par exemple en une matière plastique renforcée par fibres de verre.With this embodiment comprising two power conductors the return of the power current can be provided by one of the two conductors 10a, 10b. The conductive base 7 can then be electrically isolated from the power circuit. The base 7 could also be realized in an insulating material, for example a fiberglass reinforced plastic material.

Chaque conducteur 10a, 10b portera au moins une surface de contact 13a, 13b, non isolée et affleurante au niveau de la face 6a de la barre 6. Ces surfaces de contact sont portées ici par des plots 14a, 14b qui sont soudés chacun à une barre conductrice différente 10a, 10b et sont entourés par le matériau isolant 9.Each conductor 10a, 10b will carry at least one contact surface 13a, 13b, not isolated and flush at the face 6a of the bar 6. These contact surfaces are carried here by pads 14a, 14b which are each welded to a different conductor bar 10a, 10b and are surrounded by the insulating material 9.

Comme dans le mode de réalisation précédent, les barres de conducteurs de commande 11 et 12 sont chacune reliées à au moins une douille de contact 15a ou 15b par des liaisons filaires qui sont noyées dans le matériau isolant.As in the previous embodiment, the control conductor bars 11 and 12 are each connected to at least one contact bushing 15a or 15b by wire bonds which are embedded in the insulating material.

Les douilles de contact 15a, 15b sont affleurantes au niveau de la face 6a et sont destinées à recevoir un connecteur approprié.The contact sockets 15a, 15b are flush at the face 6a and are intended to receive a suitable connector.

Comme dans le mode de réalisation précédent, la barre bus 6 comporte plusieurs emplacements 16 tous identiques. Comme on le voit plus particulièrement sur la figure 6a, chaque emplacement 16 comprend deux surfaces de contact 13a, 13b et quatre douilles de contact 15a,15b. Les emplacements pourront être matériellement séparés les uns des autres par des surfaces de butées 17 (usinées ou collées sur la barre).As in the previous embodiment, the bus bar 6 has several locations 16 all identical. As we see more particularly on the figure 6a each location 16 comprises two contact surfaces 13a, 13b and four contact bushes 15a, 15b. The locations may be physically separated from each other by abutment surfaces 17 (machined or glued on the bar).

Chaque emplacement peut recevoir un connecteur approprié (non représenté) qui comportera d'une part des moyens assurant un raccordement au circuit de puissance 2 (via les surfaces de contact 13a et 13b) et d'autre part des moyens de raccordement aux douilles de contact 15a, 15b.Each slot can receive a suitable connector (not shown) which will comprise firstly means ensuring a connection to the power circuit 2 (via the contact surfaces 13a and 13b) and secondly means for connecting the contact sockets 15a, 15b.

Chaque emplacement comporte deux paires de douilles 15a,15b. En effet lorsqu'un organe R (ou un générateur G) est raccordé à la barre 6, il constitue également un noeud du réseau de commande / contrôle 3 piloté par le Bus de données.Each slot has two pairs of sockets 15a, 15b. Indeed, when an organ R (or a generator G) is connected to the bar 6, it also constitutes a node of the control / control network 3 driven by the data bus.

Il est donc nécessaire de prévoir une connexion en amont du noeud et une connexion en aval du noeud. Des moyens incorporés au connecteur géreront les contacts ou terminaisons de lignes nécessaires en fonction de l'état défaillant ou non du composant raccordé.It is therefore necessary to provide a connection upstream of the node and a connection downstream of the node. Means incorporated in the connector will manage the contacts or line terminations necessary depending on the state of the connected component or not.

La largeur de l'emplacement de base 16 est un standard adopté à la conception du dispositif. En fonction des courants à distribuer ou du nombre d'équipements à relier à partir d'un connecteur, un connecteur pourra recouvrir un ou deux emplacements 16.The width of the base location 16 is a standard adopted in the design of the device. Depending on the currents to be distributed or the number of devices to be connected from a connector, a connector may cover one or two locations 16.

On pourra bien entendu réaliser un réseau électrique utilisant une barre bus 6 selon ce deuxième mode de réalisation mais dans lequel chaque conducteur de puissance 10a, 10b est associé à un circuit de puissance distinct. Le retour électrique se fera alors pour les deux circuits via la masse du véhicule au travers du socle 7 qui sera alors réalisé en matériau conducteur.It will of course be possible to make an electrical network using a bus bar 6 according to this second embodiment but in which each power conductor 10a, 10b is associated with a separate power circuit. The electrical return will then be for both circuits via the mass of the vehicle through the base 7 which will then be made of conductive material.
