Description

La présente invention se rapporte au domaine technique des dispositifs de liaison et de connexion électriques. On utilise ce genre de dispositifs de liaison et de connexion notamment dans des contacteurs tournants que l'on retrouve par exemple dans des colonnes de direction d'un véhicule.The present invention relates to the technical field of electrical connection and connection devices. We use this kind of connection and connection devices, in particular in contactors turns that are found for example in steering columns of a vehicle.

Ces contacts tournants comprennent souvent un ensemble de câbles plats souples présentant chacun des pistes conductrices surmoulées. On connaít ainsi des câbles plats standards présentant six pistes conductrices (6 voies). Il est souvent nécessaire d'avoir pour un contacteur tournant une entrée sur le dispositif de liaison à douze voies, en l'occurrence deux entrées à six voies chacune et une sortie à douze voies qu'il convient de répartir en fonction de différentes fonctionnalités.These rotating contacts often include a set of flexible flat cables each having conductive tracks overmolded. We thus know standard flat cables with six conductive tracks (6 channels). It is often necessary to have for a contactor rotating an input on the twelve-way link device, in this case two inputs with six channels each and one output at twelve which should be divided according to different functionalities.

Afin d'optimiser la fabrication et le montage de tels câbles plats, dans un espace réduit, il est préférable que les deux câbles plats à six voies restent indépendants l'un de l'autre. Avec l'utilisation de câbles plats standards de six voies chacun, il est impossible d'obtenir une sortie présentant un nombre de douze voies attribuables à différentes fonctionnalités.In order to optimize the manufacture and assembly of such flat cables, in a small space, it is preferable that the two flat cables to six tracks remain independent of each other. With the use of cables standard dishes of six lanes each, it is impossible to get an exit with twelve different channels attributable to different features.

Pour certaines de ces fonctionnalités, notamment des airbags dans un véhicule, il est en outre exigé par les normes de sécurité qu'il existe une continuité électrique dans l'ensemble de la liaison électrique. Ceci impose des contraintes additionnelles dans la conception et dans l'assemblage du dispositif de liaison électrique. For some of these features, including airbags in a vehicle, it is further required by the safety standards that it There is electrical continuity throughout the electrical connection. This imposes additional constraints in the design and the assembly of the electrical connection device.

Le but de la présente invention vise à réaliser une liaison électrique ne présentant pas les inconvénients précités en augmentant notamment le nombre de possibilités d'utilisation et de liaisons électriques tout en respectant le cas échéant les normes de sécurité.The object of the present invention is to provide an electrical connection not not having the aforementioned drawbacks by, in particular, increasing the number of possibilities of use and electrical connections while respecting if necessary safety standards.

Un autre but de la présente invention vise également à faciliter les opérations de montage/démontage notamment dans des endroits difficilement accessibles, tels que commande sous volant ou contacts tournants de colonne de direction de véhicule.Another object of the present invention is also to facilitate the operations mounting / dismounting especially in hard to reach places, such as steering wheel control or rotating steering column contacts vehicle.

Le but de la présente invention vise également à éviter la conception et la fabrication d'éléments de liaison électriques particuliers en vue de répondre à des contraintes particulières et d'utiliser au mieux des éléments standards existants.The object of the present invention is also to avoid the design and manufacture of particular electrical connection elements in order to meet particular constraints and make best use of existing standard elements.

La présente invention concerne un dispositif de connexion électrique. Selon l'invention, le dispositif de connexion électrique comprend :

  • une première et une seconde grilles de connexion, pourvue chacune d'un nombre donné de bornes d'entrée et de bornes de sortie, chaque borne d'entrée étant reliée électriquement à au moins une borne de sortie via des pistes conductrices ;
  • des moyens d'assemblage entre elles des deux grilles de connexion ;
  • et des moyens de transfert de pistes conductrices attribuant, après assemblage, un nombre différent de bornes de sortie aux grilles de connexion.
The present invention relates to an electrical connection device. According to the invention, the electrical connection device comprises:
  • first and second connection grids, each provided with a given number of input terminals and output terminals, each input terminal being electrically connected to at least one output terminal via conductive tracks;
  • connecting means between them of the two connection grids;
  • and conductive track transfer means assigning, after assembly, a different number of output terminals to the connection grids.

Selon un exemple de réalisation, les grilles de connexion, une fois assemblées, sont utilisables au choix avec un nombre de bornes de sortie identique ou différent.According to an exemplary embodiment, the connection grids, once assembled, can optionally be used with a number of output terminals identical or different.

Selon un exemple de réalisation, les grilles de connexion sont montées, par exemple par clipsage, sur une pièce support isolante électrique.According to an exemplary embodiment, the connection grids are mounted by example by clipping on an electrical insulating support piece.

Selon un exemple de réalisation, les pistes conductrices sont au moins partiellement intégrées dans un support en matière isolante électrique, lequel présente des orifices dans lesquels débouchent lesdites pistes conductrices afin de réaliser les bornes d'entrée et de sortie.According to an exemplary embodiment, the conductive tracks are at least partially integrated into a support of electrical insulating material, which has orifices into which said conductive tracks open in order to make the input and output terminals.

Selon un exemple de réalisation, les pistes conductrices sont apparentes sur une face interne des grilles de connexion.According to an exemplary embodiment, the conductive tracks are apparent on an internal face of the connection grids.

Selon un exemple de réalisation, les pistes conductrices sont au moins partiellement recouvertes par une couche isolante électrique.According to an exemplary embodiment, the conductive tracks are at least partially covered by an insulating electrical layer.

Selon un exemple de réalisation, les moyens de transfert comportent au moins une piste conductrice partielle s'étendant entre la borne d'entrée correspondante et une extrémité apparente et accessible sur la face interne de la seconde grille, et au moins une piste conductrice s'étendant entre la borne de sortie correspondante et une extrémité apparente et accessible sur la face interne de la première grille, lesdites extrémités de pistes étant en contact mutuel après assemblage des grilles de connexion.According to an exemplary embodiment, the transfer means comprise at least a partial conductive track extending between the corresponding input terminal and an apparent end accessible on the internal face of the second gate, and least one conductive track extending between the corresponding output terminal and an apparent end accessible on the internal face of the first grid, said track ends being in mutual contact after assembly of the grids connection.

Selon un exemple de réalisation, au moins une piste conductrice s'étend en continuité électrique d'une part entre les bornes d'entrée et de sortie correspondantes, et d'autre part entre la borne d'entrée correspondante et l'extrémité apparente et accessible sur la face interne, présentant ainsi une configuration à deux branches sur l'une des grilles de connexion.According to an exemplary embodiment, at least one conductive track extends in electrical continuity on the one hand between the input and output terminals corresponding, and on the other hand between the corresponding input terminal and the apparent end and accessible on the inner face, thus presenting a configuration with two branches on one of the connection grids.

Selon un exemple de réalisation, la branche d'une grille s'étendant entre la borne d'entrée et l'extrémité de piste présente une élasticité améliorant le contact avec l'extrémité de piste de l'autre grille.According to an exemplary embodiment, the branch of a grid extending between the input terminal and the end of the track has an elasticity improving the contact with the end of the other grid.

Selon un exemple de réalisation, les extrémités de pistes sont solidarisées entre elles par un point de soudure, après l'assemblage des grilles de connexion.According to an exemplary embodiment, the ends of the tracks are joined together between them by a point of welding, after the assembly of the connecting grids.

Selon un exemple de réalisation, la première grille de connexion présente six bornes d'entrée et quatre bornes de sortie, la seconde grille présentant six bornes d'entrée et huit bornes de sortie, lesdites bornes de sortie étant adaptées notamment pour l'engagement de fils électriques.According to an exemplary embodiment, the first connection grid has six input terminals and four output terminals, the second gate having six terminals input terminals and eight output terminals, said output terminals being adapted especially for the engagement of electrical wires.

La présente invention concerne également un dispositif de liaison électrique comprenant deux câbles plats à six pistes conductrices chacun et reliés à l'une de leurs extrémités à un dispositif de connexion conforme à celui décrit ci-dessus.The present invention also relates to an electrical connection device consisting of two flat cables with six conductor tracks each and connected to one of their ends to a connection device according to that described above.

La présente invention concerne par ailleurs également une commande sous volant d'une colonne de direction d'un véhicule.The present invention also relates to a command under steering wheel of a steering column of a vehicle.

D'autres caractéristiques et avantages ressortiront également de la description détaillée figurant ci-après donnée à titre d'exemple en référence aux dessins annexés, dans lesquels :

  • la figure 1 est une représentation d'un dispositif de connexion standard connu en tant que tel ;
  • les figures 2 et 3 représentent chacune un élément constitutif d'un exemple de réalisation d'un dispositif de connexion électrique conforme à l'invention ;
  • les figures 4 et 5 représentent un autre exemple de réalisation d'éléments constitutifs permettant de réaliser un dispositif de connexion électrique conforme l'invention ;
  • les figures 6 et 7 représentent un exemple de réalisation d'un dispositif de liaison électrique conforme à l'invention. Le dispositif de connexion électrique de la figure 1 est un dispositif standard connu en tant que tel.
Other features and advantages will also be apparent from the following detailed description given by way of example with reference to the accompanying drawings, in which:
  • Figure 1 is a representation of a standard connection device known as such;
  • Figures 2 and 3 each represent a constituent element of an embodiment of an electrical connection device according to the invention;
  • Figures 4 and 5 show another embodiment of constituent elements for producing an electrical connection device according to the invention;
  • Figures 6 and 7 show an embodiment of an electrical connection device according to the invention. The electrical connection device of Figure 1 is a standard device known as such.

Les figures 2 et 3 représentent un exemple de réalisation d'un dispositif de connexion et plus particulièrement des éléments constitutifs dudit dispositif sur chacune des figures. Le dispositif de connexion électrique comprend une première 1 et une seconde 2 grilles de connexion pourvues chacune d'un nombre donné de bornes d'entrée 3 et de bornes de sortie 4. Chaque borne d'entrée 3 est reliée électriquement à au moins une borne de sortie 4 via une piste conductrice 5.FIGS. 2 and 3 show an exemplary embodiment of a device for connection and more particularly the constituent elements of said device on each of the figures. The electrical connection device comprises a first 1 and a second 2 connection grids each provided with a given number of input terminals 3 and output terminals 4. Each input terminal 3 is connected electrically to at least one output terminal 4 via a conductive track 5.

Le dispositif de connexion comprend également des moyens d'assemblage (non représentés) entre elles des deux grilles de connexion 1 et 2.The connection device also comprises assembly means (not shown) between them two connection grids 1 and 2.

Il est possible d'engager dans les bornes d'entrée 3 l'extrémité d'un câble plat 6 souple, pourvu de pistes conductrices 5. Les bornes de sortie 4 sont en outre configurées pour permettre l'engagement de câbles électriques 7. D'autres éléments de liaison électriques tels qu'un peigne, peuvent également être prévus pour être engagés dans les bornes de sortie (4).It is possible to engage in the input terminals 3 the end of a flat cable 6 flexible, provided with conductive tracks 5. The output terminals 4 are furthermore configured to allow the engagement of electrical cables 7. Others electrical connection elements such as a comb, can also be provided to be engaged in the output terminals (4).

Le dispositif de connexion conforme à l'invention comporte également des moyens de transfert de pistes conductrices 5, attribuant après assemblage des grilles de connexion 1 et 2; un nombre différent de bornes de sortie 4 aux grilles de connexion 1 et 2. On obtient ainsi, en se reportant par exemple aux figures 4 et 5, une première grille de connexion 1 présentant huit bornes de sortie 4 et une seconde grille de connexion 2 présentant quatre bornes de sortie 4.The connection device according to the invention also comprises means for transfer of conductive tracks 5, attributing after assembly connection grids 1 and 2; a different number of output terminals 4 to the grids of connection 1 and 2. Thus, referring for example to Figures 4 and 5, a first lead frame 1 having eight output terminals 4 and a second lead frame 2 having four output terminals 4.

Selon l'exemple de réalisation représenté par exemple aux figures 2 et 3 les grilles de connexion 1 et 2 une fois assemblées, sont utilisables au choix avec un nombre de bornes de sortie 4 identique ou différent. L'utilisateur peut disposer d'une première série de bornes de sortie 4 au nombre de huit et une seconde série de bornes de sortie 4 au nombre de quatre selon une première variante d'utilisation ou utiliser de façon standard le dispositif de connexion de manière à disposer de deux grilles de connexion 1 et 2 présentant chacune six bornes de sortie 4. L'une d'entre elles bénéficie alors de deux bornes de sortie 4 inutilisées. Il est ainsi possible avec des éléments standards de s'adapter à des cas particuliers de câblage ou à des configurations, notamment dans l'assemblage de contacts tournants d'une colonne de direction. La possibilité de répartir des pistes conductrices 5 entre les grilles 1 et 2 est particulièrement intéressante sur le plan technique et sur le plan économique.According to the exemplary embodiment represented for example in FIGS. Connection grids 1 and 2, once assembled, can be used with a number of output terminals 4 identical or different. The user can have of a first series of output terminals 4 to the number of eight and a second series of output terminals 4 to four in a first variant of use or use the connection device as a standard so as to have two connection grids 1 and 2 each having six terminals output 4. One of them then benefits from two unused output terminals 4. he is thus possible with standard elements to adapt to particular cases wiring or configurations, particularly in contact assembly turn of a steering column. The possibility of distributing tracks conductors 5 between the grids 1 and 2 is particularly interesting in terms of technical and economic.

Selon un exemple de réalisation, les grilles de connexion 1 et 2 sont montées par exemple par clipsage sur une pièce support isolante électrique. Les grilles de connexion 1 et 2 peuvent ainsi venir enserrer, sous forme de structure sandwich, la pièce support. Les pistes conductrices 5 et les grilles de connexion 1 et 2 sont au moins partiellement intégrées dans un support en matière isolante électrique, lequel présente des orifices dans lesquels débouchent lesdites pistes conductrices 5 afin de réaliser les bornes d'entrée 3 et de sortie 4. Le support en matière isolante électrique est par exemple à base de Polyamides chargés d'un matériau plastique, par exemple référencé par PA 6.6 GF 30.According to an exemplary embodiment, the connection grids 1 and 2 are mounted for example by clipping on an electrical insulating support part. The grids of connection 1 and 2 can thus come together, in the form of a sandwich structure, the support piece. The conductive tracks 5 and the connection grids 1 and 2 are at least partially integrated in a support of electrical insulating material, which has orifices into which said conductive tracks 5 open in order to to make the input terminals 3 and output 4. The support of insulating material electric is for example based on polyamides loaded with a plastic material, for example referenced by PA 6.6 GF 30.

Les pistes conductrices 5 sont par exemple apparentes sur une face interne des grilles de connexion 1 et 2. Les pistes conductrices 5 sont de préférence au moins partiellement recouvertes par une couche isolante électrique. On évite ainsi des risques de court-circuit lorsque les grilles de connexion 1 et 2 sont assemblées directement sans pièce support réalisant l'interface.The conductive tracks 5 are for example apparent on an inner face connection gates 1 and 2. The conductive tracks 5 are preferably less partially covered by an electrical insulating layer. This avoids short-circuit risks when connection grids 1 and 2 are assembled directly without support part realizing the interface.

Les moyens de transfert comportent par exemple au moins une piste conductrice partielle 8 s'étendant entre la borne d'entrée 3 correspondante et une extrémité apparente et accessible 9 sur la face interne de la seconde grille de connexion 2.The transfer means comprise for example at least one track partial conductor 8 extending between the corresponding input terminal 3 and a visible and accessible end 9 on the inner face of the second grid of connection 2.

Les moyens de transfert comportent également au moins une piste conductrice complémentaire 10 s'étendant entre la borne de sortie 4 correspondante et une extrémité apparente et accessible 12 complémentaire sur la face interne de la première grille 1. Les extrémités de pistes 9 et 12 sont alors en contact après l'assemblage des grilles de connexion 1 et 2. On obtient ainsi avec deux câbles plats 6 standards, présentant six voies (six pistes conductrices 5) chacun, une configuration dans laquelle le dispositif de connexion conforme à l'invention, constituant une des extrémités des câbles plats 6, permet d'obtenir une solution équivalente à l'utilisation d'un câbles plat 6 à quatre voies et d'un câble plat 6 complémentaire à huit voies. On pourra par exemple se reporter aux figures 6 et 7. L'avantage de la solution conforme à l'invention réside dans l'utilisation de câbles standards, évitant la fabrication de câbles spécifiques. Les éléments de connexion 13 et 14 présentant par exemple une configuration de deux fois deux voies et de huit voies respectivement, peuvent ainsi être connectés sur le dispositif de connexion conforme à l'invention. L'autre extrémité des câbles plats 6 est raccordée à un élément de connexion standard 15 connu en tant que tel.The transfer means also comprise at least one conductive track 10 extending between the corresponding output terminal 4 and a apparent end and accessible 12 complementary on the inner face of the first grid 1. The ends of lanes 9 and 12 are then in contact after the connection grids 1 and 2 are assembled. This is achieved with two cables 6 standard dishes, with six channels (six conductor tracks 5) each, one configuration in which the connection device according to the invention, constituting one of the ends of the flat cables 6, provides a solution equivalent to the use of a four-way flat cable 6 and a flat cable 6 complementary to eight channels. For example, reference can be made to FIGS. 7. The advantage of the solution according to the invention lies in the use of cables standards, avoiding the manufacture of specific cables. Connection elements 13 and 14 having for example a configuration of two times two ways and eight channels respectively, can thus be connected to the device of connection according to the invention. The other end of the flat cables 6 is connected to a standard connection element known as such.

On obtient ainsi l'avantage d'avoir en combinaison d'une part les pistes conductrices 5 présentant une parfaite continuité électrique et satisfaisant par conséquent à des normes de sécurité en vigueur comme c'est le cas par exemple pour le fonctionnement d'organes de sécurité tels que des airbags, et d'autre part des pistes conductrices 5 dont la continuité électrique ne nécessite pas de satisfaire à des critères de sécurité aussi élevés, notamment dans la commande de fonctionnalité telle qu'une radio.This gives the advantage of having in combination on the one hand the tracks 5 having a perfect electrical continuity and satisfying by safety standards in force as is the case, for example for the operation of safety devices such as airbags, and secondly conductive tracks 5 whose electrical continuity does not require to satisfy such high safety standards, particularly in the control of functionality such as a radio.

On peut par exemple relier la seconde grille de connexion 2 électriquement à des airbags et la première grille de connexion 1 à un dispositif de commande ou de contrôle d'un autoradio.For example, it is possible to connect the second connection grid 2 electrically to airbags and the first lead frame 1 to a control device or control of a car radio.

Dans le dispositif de connexion électrique représenté par exemple aux figures 2 et 3, au moins une piste conductrice 5 s'étend en continuité électrique d'une part entre les bornes d'entrée 3 et de sortie 4 correspondantes, et d'autre part entre la borne d'entrée 3 correspondante et l'extrémité apparente et accessible 9 sur la face interne. La piste conductrice 5 présente ainsi une configuration à deux branches 16 et 17, l'une principale 16 et l'autre additionnelle 17. L'utilisateur du dispositif de connexion électrique peut ainsi faire un choix dans le nombre de bornes de sortie 4 respectives pour chacune des grilles de connexion 1 et 2.In the electrical connection device shown for example in the figures 2 and 3, at least one conductive track 5 extends in electrical continuity on the one hand between the corresponding input 3 and output 4 terminals, and on the other hand between the corresponding input terminal 3 and the apparent and accessible end 9 on the internal face. The conductive track 5 thus has a configuration with two branches 16 and 17, one main 16 and the other additional 17. The user of the device electrical connection can thus make a choice in the number of output terminals 4 respective for each of the connection grids 1 and 2.

Selon un exemple de réalisation, la branche additionnelle 17 ou la piste conductrice partielle 8 ou la piste complémentaire 10 présente une élasticité améliorant le contact entre les extrémités de piste 9 et 12.According to an exemplary embodiment, the additional branch 17 or the track partial conductor 8 or the complementary track 10 has an elasticity improving the contact between the track ends 9 and 12.

Les extrémités de piste 9 et 12 sont par exemple solidarisées entre elles par un point de soudure après l'assemblage des grilles de connexion 1 et 2. Ces dernières présentent avantageusement un dégagement de matière ou une fenêtre permettant d'accéder aux extrémités de piste 9 et 12 de manière à réaliser l'opération de soudure.The ends of the track 9 and 12 are for example secured together by a weld spot after assembling the connection grids 1 and 2. These latter advantageously have a clearance of material or a window allowing access to the ends of lanes 9 and 12 so as to realize the welding operation.

Selon un exemple de réalisation et d'utilisation d'un dispositif conforme à l'invention, la première grille 1 présente six bornes d'entrée 3 et huit bornes de sortie 4, tandis que la seconde grille de connexion 2 présente six bornes d'entrée 3 et quatre bornes de sortie 4.According to an exemplary embodiment and use of a device according to the invention, the first gate 1 has six input terminals 3 and eight terminals of output 4, while the second lead frame 2 has six input terminals 3 and four output terminals 4.

L'ensemble des bornes de sortie sont par exemple adaptées notamment à l'engagement de fils électriques 7.The set of output terminals are for example adapted especially to the engagement of electric wires 7.

Le dispositif de connexion conforme à l'invention permet ainsi de réaliser un dispositif de liaison électrique tel que représenté par exemple aux figures 6 et 7. Ces dispositifs de liaison électriques sont particulièrement bien adaptés à l'utilisation dans des contacts tournants de colonnes de direction d'un véhicule ou dans des commandes sous volant d'un véhicule. Il est souvent nécessaire d'obtenir dans les applications précitées un encombrement minimum pour les dispositifs de liaison électrique, lesquels, conformes à l'invention répondent bien à ces exigences techniques.The connection device according to the invention thus makes it possible to electrical connection device as shown for example in Figures 6 and 7. These electrical connection devices are particularly well adapted to use in rotating contacts of steering columns of a vehicle or in controls under the steering wheel of a vehicle. It is often necessary to obtain in the aforementioned applications a minimum space requirement for the devices of electrical connection, which, in accordance with the invention meet these requirements well techniques.
