Le système de connexion électrique 100 comporte en outre un premier conducteur électrique qui est, dans l'exemple décrit, sous la forme d'une barre omnibus 112. Une barre omnibus est un conducteur de faible impédance auquel peuvent être reliés plusieurs circuits électriques en des points séparés. La barre omnibus est en particulier sous forme de lame.The electrical connection system 100 further comprises a first electrical conductor which is, in the example described, in the form of a bus bar 112. A busbar is a low-impedance conductor to which several electrical circuits can be connected together. separate points. The bus bar is in particular in the form of a blade.

La barre omnibus 112 traverse de manière étanche une des parois latérales 104 de l'alvéole 102 de manière à présenter une partie extérieure 114 s'étendant à l'extérieur de l'alvéole 102 et une partie intérieure 116 s'étendant dans l'alvéole 102. Par exemple, l'alvéole 102 est surmoulée autour de la barre omnibus 112. Ainsi, l'ouverture 108 de l'alvéole 102 est la seule ouverture non étanche de l'alvéole 102. La partie intérieure 116 de la barre omnibus 112 présente un coude et se projette en direction de l'ouverture 108 de l'alvéole 102, entre les deux rebords 110A, 110B. La partie intérieure 116 de la barre omnibus 112 présente une extrémité définissant un contact mâle sous la forme d'une fiche électrique 118 pointant vers l'ouverture 108. La fiche 118 est plate et présente deux grandes faces opposées munies chacune d'un creux destiné à recevoir un crochet comme cela sera décrit par la suite. Dans l'exemple décrit, la fiche 118 est perforée par un trou traversant 120 reliant ses deux grandes faces opposées. Les deux extrémités du trou traversant 120 définissent respectivement les deux creux.The bus bar 112 seals one of the side walls 104 of the cell 102 so as to have an outer portion 114 extending outside the cell 102 and an inner portion 116 extending into the cell 102. For example, the cell 102 is overmolded around the bus bar 112. Thus, the opening 108 of the cell 102 is the only the unsealed opening of the cell 102. The inner portion 116 of the bus bar 112 has a bend and projects towards the opening 108 of the cell 102, between the two flanges 110A, 110B. The inner portion 116 of the bus bar 112 has one end defining a male contact in the form of an electrical plug 118 pointing to the opening 108. The plug 118 is flat and has two large opposite faces each provided with a recess for to receive a hook as will be described later. In the example described, the plug 118 is perforated by a through hole 120 connecting its two large opposite faces. The two ends of the through hole 120 respectively define the two recesses.

Le système de connexion électrique 100 comporte en outre un connecteur électrique 122 destiné à connecter électriquement ensemble la barre omnibus 112 à un autre conducteur électrique 123, qui, dans l'exemple décrit, est sous la forme d'une fiche électrique plate (contact mâle).The electrical connection system 100 further comprises an electrical connector 122 for electrically connecting together the bus bar 112 to another electrical conductor 123, which, in the example described, is in the form of a flat electrical plug (male contact ).

Dans l'exemple décrit, le connecteur 122 fait moins de 20 mm de haut (dans la direction haut/bas H-B), par exemple 10 mm ou 15 mm, et moins de 15 mm en largeur (dans la direction droite/gauche D-G), par exemple 10 mm.In the example described, the connector 122 is less than 20 mm high (in the up / down direction HB), for example 10 mm or 15 mm, and less than 15 mm in width (in the right / left direction DG) for example 10 mm.

Le connecteur 122 comporte tout d'abord un corps 124. Dans l'exemple décrit, le corps 124 est en forme d'anneau autour de la direction haut/bas H-B, l'anneau étant de forme générale sensiblement cylindrique creuse. Dans le cadre de la présente demande, on entend par cylindre, un cylindre de révolution ou un prisme tel qu'un cube ou un parallélépipède. L'anneau présente une section rectangulaire avec les coins arrondis. Alternativement, l'anneau pourrait présenter une section circulaire ou ovale. Le corps 124 présente ainsi deux flancs longs 124A dans la direction droite/gauche D-G et deux flancs courts 124B dans la direction avant/arrière Av-Ar.The connector 122 first comprises a body 124. In the example described, the body 124 is in the form of a ring around the up / down direction H-B, the ring being generally of substantially hollow cylindrical shape. In the context of the present application, cylinder means a cylinder of revolution or a prism such as a cube or a parallelepiped. The ring has a rectangular section with rounded corners. Alternatively, the ring could have a circular or oval section. The body 124 thus has two long flanks 124A in the right / left direction D-G and two short flanks 124B in the forward / backward direction Av-Ar.

Le connecteur 122 comporte un premier contact 126 fixé au corps 124 et s'étendant vers le haut depuis le corps 124. Dans l'exemple décrit, le premier contact 126 est un contact femelle comportant deux pinces 128, 130 ouvertes vers le haut, s'étendant parallèlement l'une à l'autre et définissant une fente supérieure 132 d'insertion du conducteur électrique 123. Dans d'autres modes de réalisation, le premier contact 126 pourrait ne comporter qu'une seule pince. La fente 132 s'étend dans la direction droite/gauche. Chaque pince 128, 130 comporte deux branches de contact 128A, 128B et 130A, 130B s'étendant l'une en face de l'autre depuis le corps 124, et plus précisément depuis respectivement les deux flancs longs 124A du corps. Les deux branches de contact 128A, 128B et 130A, 130B d'une même pince 128, 130 se rapprochent l'une de l'autre en direction de leurs extrémités libres à la manière d'une lyre: chaque extrémité libre possède une forme arquée dont la concavité est orientée vers l'extérieur de la fente 132 de sorte que les extrémités libres offrent une surface convexe vers l'intérieur de la fente 132. Chaque extrémité libre comporte un bossage formant un renflement vers l'intérieur de la fente 132. Le bossage permet ainsi un contact point-point entre la branche de contact 128A, 128B, 130A, 130B sur laquelle il se trouve et la fiche plate introduite dans la fente 132. Chaque bossage peut être obtenu par déformation localisée de l'extrémité libre, par exemple par emboutissage. Les bossages permettent de minimiser les résistances électriques. La présence de deux pinces 128, 130 permet au premier contact 126 de pouvoir s'adapter à la forme de la fiche, par exemple si celle-ci n'est pas tout à fait plane ou bien présente une épaisseur variable.The connector 122 has a first contact 126 fixed to the body 124 and extending upwardly from the body 124. In the example described, the first contact 126 is a female contact having two clamps 128, 130 open upwards, extending parallel to each other and defining an upper slot 132 for inserting the electrical conductor 123. In other embodiments, the first contact 126 could have only one clamp. Slot 132 extends in the right / left direction. Each clamp 128, 130 has two contact legs 128A, 128B and 130A, 130B extending opposite each other from the body 124, and more precisely since respectively the two long flanks 124A of the body. The two contact legs 128A, 128B and 130A, 130B of the same clamp 128, 130 approach each other towards their free ends in the manner of a lyre: each free end has an arched shape whose concavity is oriented towards the outside of the slot 132 so that the free ends provide a convex surface towards the inside of the slot 132. Each free end has a boss forming a bulge towards the inside of the slot 132. The boss thus allows a point-to-point contact between the contact leg 128A, 128B, 130A, 130B on which it is located and the flat plug inserted into the slot 132. Each boss can be obtained by localized deformation of the free end, for example by stamping. The bosses minimize the electrical resistance. The presence of two clamps 128, 130 allows the first contact 126 to adapt to the shape of the plug, for example if it is not quite flat or has a variable thickness.

Le connecteur 122 comporte en outre un second contact 134 similaire au premier contact 126. Le second contact 134 est ainsi fixé au corps 124 et s'étend vers le bas depuis le corps 124. Dans l'exemple décrit, le second contact 134 est un contact femelle comportant deux pinces 136, 138 ouvertes vers le bas, s'étendant parallèlement l'une à l'autre et définissant une fente inférieure 140 d'insertion de la fiche 118 s'étendant dans l'alvéole 102. Dans d'autres modes de réalisation, le second contact 134 pourrait ne comporter qu'une seule pince. La fente 140 s'étend dans la direction droite/gauche. Chaque pince 136, 138 comporte deux branches de contact 136A, 136B et 138A, 138B s'étendant l'une en face de l'autre depuis le corps 124. Les deux branches de contact 136A, 136B et 138A, 138B d'une même pince 136, 138 se rapprochent l'une de l'autre en direction de leurs extrémités libres à la manière d'une lyre: chaque extrémité libre possède une forme arquée dont la concavité est orientée vers l'extérieur de la fente 140 de sorte que les extrémités libres offrent une surface convexe vers l'intérieur de la fente 140. Chaque extrémité libre comporte un bossage formant un renflement vers l'intérieur de la fente 140. Le bossage permet ainsi un contact point-point entre la branche de contact 136A, 136B, 138A, 138B sur laquelle il se trouve et la fiche 118 introduite dans la fente 140. Chaque bossage peut être obtenu par déformation localisée de l'extrémité de libre, par exemple par emboutissage. Les bossages permettent de minimiser les résistances électriques. La présence de deux pinces 136, 138 permet au second contact 134 de pouvoir s'adapter à la forme de la fiche, par exemple si celle-ci n'est pas tout à fait plane ou bien présente une épaisseur variable.The connector 122 further comprises a second contact 134 similar to the first contact 126. The second contact 134 is thus fixed to the body 124 and extends downwardly from the body 124. In the example described, the second contact 134 is a female contact having two clamps 136, 138 open downwards, extending parallel to each other and defining a lower slot 140 insertion of the plug 118 extending into the cell 102. In others Embodiments, the second contact 134 could have only one clamp. Slot 140 extends in the right / left direction. Each clamp 136, 138 has two contact legs 136A, 136B and 138A, 138B extending opposite one another from the body 124. The two contact branches 136A, 136B and 138A, 138B of the same pliers 136, 138 are moving towards each other towards their free ends in the manner of a lyre: each free end has an arcuate shape whose concavity is oriented towards the outside of the slot 140 so that the free ends provide a convex surface towards the inside of the slot 140. Each free end has a boss forming a bulge towards the inside of the slot 140. The boss thus allows a point-to-point contact between the contact branch 136A, 136B, 138A, 138B on which it is located and the plug 118 introduced into the slot 140. Each boss can be obtained by localized deformation of the free end, for example by stamping. The bosses minimize the electrical resistance. The presence of two clamps 136, 138 allows the second contact 134 to be adapted to the shape of the plug, for example if it is not quite flat or has a variable thickness.

Dans l'exemple illustré sur la figure 1, le connecteur 122 présente ainsi deux fois deux points de contact avec chacune des fiches qu'il est destiné à recevoir pour les connecter électriquement ensemble.In the example shown on the figure 1 , the connector 122 thus has twice two points of contact with each of the plugs that it is intended to receive to electrically connect them together.

Le connecteur 122 comporte en outre un système d'attache du connecteur 122 à la fiche 118, ce système d'attache étant distinct du second contact 134. Le système d'attache est fixé au corps 134 et est destiné à s'accrocher à la fiche 118 lors de l'engagement du second contact 134 sur la fiche 118. Le système d'attache est fixé au corps 124 du connecteur 122.The connector 122 further comprises a system for attaching the connector 122 to the plug 118, this fastening system being distinct from the second contact 134. The fastening system is fixed to the body 134 and is intended to catch on the plug 118 when engaging second contact 134 on plug 118. The fastening system is attached to body 124 of connector 122.

Dans l'exemple décrit, le système d'attache comporte deux crochets 142, 144 fixés au corps 124 et s'étendant vers le bas depuis le corps 124, l'un en face de l'autre. Plus précisément, les deux crochets 142, 144 sont fixés sur respectivement les deux flancs longs 124A du corps 124, chacun entre les deux pinces 136, 138. Les crochets 142, 144 présentent des extrémités libres recourbées vers la fente 140, qui sont destinées à s'engager respectivement dans les creux de la fiche 118 pour maintenir le second contact 134 sur la fiche 118. Le fait que les crochets soient fixés l'un en face de l'autre et le fait qu'ils soient situés entre les pinces 136, 138 permet d'obtenir une connexion stable entre le connecteur 122 et la fiche 118.In the example described, the fastening system comprises two hooks 142, 144 attached to the body 124 and extending downwardly from the body 124, facing each other. More specifically, the two hooks 142, 144 are attached to the two long flanks 124A of the body 124, each between the two clamps 136, 138. The hooks 142, 144 have free ends bent towards the slot 140, which are intended for respectively engaging in the recesses of the plug 118 to maintain the second contact 134 on the plug 118. The fact that the hooks are fixed opposite each other and the fact that they are located between the clamps 136 , 138 makes it possible to obtain a stable connection between the connector 122 and the plug 118.

Par ailleurs, dans l'exemple décrit, le connecteur 122, et en particulier le corps 124, les deux contacts 126, 134 et les crochets 142, 144 sont formés à partir d'une unique plaque ou feuille de métal, pliée et/ou emboutie et/ou poinçonnée. Le connecteur 122 forme ainsi un ensemble monobloc. Le métal utilisé peut être de toute nature appropriée et notamment présenter des traitements de surface adaptés en fonction de la manière dont le connecteur 122 est fixé sur la fiche 118. La plaque/feuille de métal a de préférence une épaisseur de moins de 1,5 mm, par exemple comprise entre 0,6 mm et 1 mm.Furthermore, in the example described, the connector 122, and in particular the body 124, the two contacts 126, 134 and the hooks 142, 144 are formed from a single plate or sheet of metal, folded and / or stamped and / or punched. The connector 122 thus forms a one-piece assembly. The metal used can be of any suitable nature and in particular have surface treatments adapted according to the way the connector 122 is fixed on the plug 118. The plate / sheet of metal preferably has a thickness of less than 1.5. mm, for example between 0.6 mm and 1 mm.

Ainsi, le corps 124 comporte une bande enroulée sur elle-même pour former un cylindre. La bande présente deux côtés longs et deux côtés courts d'extrémité. Les branches 128A, 128B, 130A, 130B, 136A, 136B, 138A, 138B des pinces 128, 130, 136, 138 et les crochets 142, 144 sont respectivement formés par des languettes se projetant depuis les côtés longs de la bande.Thus, the body 124 comprises a band wound on itself to form a cylinder. The band has two long sides and two short end sides. The branches 128A, 128B, 130A, 130B, 136A, 136B, 138A, 138B of the clamps 128, 130, 136, 138 and the hooks 142, 144 are respectively formed by tongues projecting from the long sides of the band.

En référence à la figure 2, le connecteur 122 est destiné à être introduit dans l'alvéole 102 et à contacter la fiche 118 pour établir une connexion électrique.With reference to the figure 2 , the connector 122 is intended to be introduced into the cell 102 and to contact the plug 118 to establish an electrical connection.

Plus précisément, la fiche 118 est destinée à entrer dans la fente 140 lors de l'insertion du connecteur 122 au travers de l'ouverture 108. Ce faisant, la fiche 118 écarte les branches 136A, 136B, 138A, 138B des pinces 136, 138 du second contact 134, ainsi que les deux crochets 142. Les branches 136A, 136B, 138A, 138B sont flexibles de manière à assurer un bon effort de contact. Ainsi, les pinces 136, 138 du second contact 134 enserrent la fiche 118.More specifically, the plug 118 is intended to enter the slot 140 during the insertion of the connector 122 through the opening 108. In doing so, the plug 118 spreads the branches 136A, 136B, 138A, 138B of the clamps 136, 138 of the second contact 134, as well as the two hooks 142. The branches 136A, 136B, 138A, 138B are flexible so as to ensure a good contact force. Thus, the clamps 136, 138 of the second contact 134 grip the plug 118.

Le connecteur 122 est introduit jusqu'à ce que les flancs courts 124B du corps 124 soient arrêtés par les faces d'arrêt des rebords 110A, 110B et reposent sur ces dernières. La présence des deux rebords 110A, 110B sur deux parois latérales 104 opposées de l'alvéole 102 permet de contrôler l'inclinaison du connecteur 122 autour de la direction avant/arrière Av-Ar.The connector 122 is introduced until the short sides 124B of the body 124 are stopped by the stop faces of the flanges 110A, 110B and rest on the latter. The presence of the two flanges 110A, 110B on two opposite side walls 104 of the cell 102 makes it possible to control the inclination of the connector 122 around the forward / backward direction Av-Ar.

Au moment de l'arrêt par les rebords 110A, 110B, les deux crochets 142, 144 engagent respectivement les deux creux formés par le trou traversant 120 pour maintenir en place le connecteur 122 sur la fiche 118, dans l'alvéole 102.At the time of the stop by the flanges 110A, 110B, the two hooks 142, 144 respectively engage the two hollow formed by the hole through 120 to keep in place the connector 122 on the plug 118, in the cell 102.

De préférence, les rebords 110A, 110B sont plus petits que les flancs courts 124B du corps 124 du connecteur 122. Ainsi, le connecteur 122 peut pivoter sur les rebords 110A, 110B autour de la direction droite/gauche D-G pour, par exemple, rattraper des jeux.Preferably, the flanges 110A, 110B are smaller than the short flanks 124B of the body 124 of the connector 122. Thus, the connector 122 can pivot on the flanges 110A, 110B around the right / left direction DG to, for example, catch up games.

Il est alors possible d'insérer l'autre conducteur électrique 123 dans la fente 132 du premier contact 126, de la même manière que la fiche 118 avec le second contact 134, afin de réaliser une connexion électrique entre cet autre conducteur électrique 123 et la barre omnibus 112 via le connecteur 122.It is then possible to insert the other electrical conductor 123 in the slot 132 of the first contact 126, in the same manner as the plug 118 with the second contact 134, in order to make an electrical connection between this other electrical conductor 123 and the bus bar 112 via the connector 122.

En référence aux figures 3 et 4, le corps 124 du connecteur 122 comporte en outre des doigts 302, 304, 306 s'étendant depuis les côtés courts de la bande du corps 124. Les doigts 302, 304, 306 sont destinés à s'engrener les uns dans les autres afin de maintenir la bande enroulée lorsque, en particulier, des fiches sont insérées dans les pinces des contacts 126, 134. Dans l'exemple décrit, un premier côté court présente deux doigts 302, 304, tandis que l'autre côté court présente un doigt destiné à s'intercaler entre les deux doigts 302, 304.With reference to figures 3 and 4 the body 124 of the connector 122 further includes fingers 302, 304, 306 extending from the short sides of the body strip 124. The fingers 302, 304, 306 are intended to mesh with one another to to maintain the wound strip when, in particular, plugs are inserted into the tongs of the contacts 126, 134. In the example described, a first short side has two fingers 302, 304, while the other short side has a finger intended to be inserted between the two fingers 302, 304.

Le système de connexion électrique 100 peut par exemple être employé pour connecter un boîtier d'alimentation à un moteur de direction assisté d'un véhicule automobile. Dans ce cas, la barre omnibus est connectée électriquement à l'un parmi le boîtier d'alimentation et le moteur, tandis que le conducteur électrique 123 appartient à autre barre omnibus connectée électriquement à l'autre parmi le boîtier d'alimentation et le moteur.The electrical connection system 100 may for example be used to connect a power supply unit to a power steering motor of a motor vehicle. In this case, the bus bar is electrically connected to one of the power box and the motor, while the electrical conductor 123 belongs to another bus bar electrically connected to the other one of the power box and the motor. .

L'invention est particulièrement intéressante dans ce cas, car, tout d'abord, le boîtier d'alimentation et le moteur de direction assistée se trouvent généralement dans un environnement encombré de sorte que la barre omnibus 112 est difficile d'accès. Ce problème est résolu par le fait que le connecteur 122 est guidé par les parois latérales 104 de l'alvéole et s'accroche automatiquement à la barre omnibus 112 lors de son insertion dans l'alvéole. En outre, lors du montage du véhicule automobile, il est souvent nécessaire de débrancher et rebrancher à de nombreuses reprises le boîtier d'alimentation, pour réaliser par exemple des tests ou des réglages. Or, le premier contact 126 peut recevoir le conducteur électrique 123 de manière amovible, c'est-à-dire que ce conducteur électrique peut facilement être désengagé du premier contact 126.The invention is particularly interesting in this case because, first of all, the power box and the power steering motor are generally in a congested environment so that the bus bar 112 is difficult to access. This problem is solved by the fact that the connector 122 is guided by the side walls 104 of the cell and automatically clings to the bus bar 112 when inserted. in the cell. In addition, when mounting the motor vehicle, it is often necessary to repeatedly disconnect and reconnect the power supply, for example to perform tests or adjustments. However, the first contact 126 can receive the electrical conductor 123 removably, that is to say that the electrical conductor can easily be disengaged from the first contact 126.

La présente invention n'est pas limitée au mode de réalisation décrit précédemment, mais est au contraire définie par les revendications qui suivent. Il sera en effet apparent à l'homme du métier que des modifications peuvent y être apportées.The present invention is not limited to the embodiment described above, but is instead defined by the following claims.
