Abstract

An interconnection strip for electrically connecting at least two printed circuits (16, 17). The strip is characterised in that not all the ends of the connecting pins (12) are in alignment, and the receiving holes (15) in the printed circuits (16, 17) do not form a weakened area. Said strip is particularly useful for connecting a flexible printed circuit to another (flexible or non-flexible) printed circuit, especially in an on-board electronic system for motor vehicles.

Description

Barrette d'interconnexion pour circuits imprimés Interconnection strip for printed circuits

La présente invention concerne une barrette d'interconnexion adaptée pour relier électriquement au moins deux circuits imprimés. Plus particulièrement au moins l'un de ces deux circuits est un circuit imprimé flexible.The present invention relates to an interconnection strip adapted to electrically connect at least two printed circuits. More particularly at least one of these two circuits is a flexible printed circuit.

Dans le domaine de l'électronique automobile on cherche de plus en plus à réduire les dimensions et le poids des systèmes électroniques embarqués à bord des véhicules. A cet effet, on utilise notamment des circuits imprimés sur feuille flexible et non plus sur plaque rigide. De tels circuits flexibles présentent cependant l'inconvénient d'être plus fragiles que les circuits rigides et notamment de se déchirer plus facilement. Par ailleurs il est déjà connu de relier deux circuits imprimés l'un à l'autre. A cet effet on utilise des barrettes d'interconnexion présentant une pluralité de broches alignées reliant chacun des circuits. Pour connecter ces broches avec chaque circuit il est nécessaire de prévoir une pluralité d'orifices de réception dans le circuit. Ces orifices de réception génèrent une zone de fragilisation (une ligne de rupture dans le circuit imprimé). Lorsqu'il s'agit d'un circuit imprimé rigide cela ne porte pas à conséquence, mais dans le cas d'un circuit imprimé flexible cela favorise une déchirure du circuit.In the field of automotive electronics, there is an increasing effort to reduce the dimensions and the weight of electronic systems on board vehicles. To this end, printed circuits are used in particular on flexible sheet and no longer on rigid plate. However, such flexible circuits have the drawback of being more fragile than rigid circuits and in particular of tearing more easily. Furthermore, it is already known to connect two printed circuits to one another. To this end, interconnection bars are used having a plurality of aligned pins connecting each of the circuits. To connect these pins with each circuit, it is necessary to provide a plurality of receiving orifices in the circuit. These receiving holes generate a weakening zone (a line of rupture in the printed circuit). In the case of a rigid printed circuit this is not of consequence, but in the case of a flexible printed circuit this promotes a tearing of the circuit.

Pour pallier cet inconvénient on peut renforcer la structure du circuit imprimé flexible au niveau de sa jonction avec la barrette d'interconnexion. Mais un tel renforcement même s'il résout le problème des déchirures va à rencontre des objectifs fixés à savoir: la simplification, l'allégement et la réduction de l'encombrement et des coûts des systèmes électroniques embarqués dans un véhicule automobile.To overcome this drawback, the structure of the flexible printed circuit can be reinforced at its junction with the interconnection strip. But such reinforcement, even if it solves the problem of tears, runs counter to the objectives set, namely: simplification, reduction and reduction in the size and costs of the electronic systems on board a motor vehicle.

L'objet de la présente invention est de pallier l'ensemble de ces inconvénients et de relier ensemble deux circuits dont l'un peut être flexible sans fragiliser la zone de liaison.The object of the present invention is to overcome all of these drawbacks and to link together two circuits, one of which can be flexible without weakening the connection area.

A cet effet la présente invention, concerne une barrette d'interconnexion adaptée pour relier électriquement au moins deux circuits imprimés, la dite barrette comportant un support logeant une pluralité de broches conductrices présentant chacune deux extrémités adaptées chacune pour assurer une mise en contact électrique avec l'un des circuits imprimés, la dite barrette étant caractérisée en ce que les extrémités des broches conductrices en contact avec un même circuit imprimé sont disposées selon au moins deux droites de connexion distinctes. Grâce à de telles dispositions, la réalisation des perforations de réception des broches ne crée pas une ligne de rupture et le circuit imprimé (notamment lorsqu'il s'agit d'un circuit flexible) n'est pas fragilisé dans cette zone de jonction.To this end, the present invention relates to an interconnection strip adapted to electrically connect at least two printed circuits, said strip comprising a support housing a plurality of conductive pins each having two ends each adapted to ensure electrical contact with the 'one of the printed circuits, said strip being characterized in that the ends of the conductive pins in contact with the same printed circuit are arranged along at least two separate connection lines. Thanks to such arrangements, the realization of the pin receiving perforations does not create a breaking line and the printed circuit (especially when it is a flexible circuit) is not weakened in this junction zone.

Avantageusement en réalisant les perforations du circuit imprimé sur au moins deux lignes on élargit la zone de jonction de la barrette d'interconnexion avec le circuit imprimé flexible ce qui évite de fragiliser le circuit imprimé. Aucun renfort spécifique n'est alors nécessaire.Advantageously, by making the perforations of the printed circuit on at least two lines, the area of junction of the interconnection strip with the flexible printed circuit is enlarged, which avoids weakening the printed circuit. No specific reinforcement is then necessary.

Selon un mode préférentiel de réalisation les broches se connectent alternativement sur deux droites de connexion distinctes et parallèles. En variante ces connexions sont réalisées de manière régulière mais non alternative. De manière avantageuse les barrettes de connexions selon l'invention, sont réalisées en grande longueur et découpées sur mesure au moment de leur utilisation. En outre, on notera que ces barrettes sont totalement réversibles. De ce fait il n'existe pas de sens de pose privilégié ce qui facilite leur mise en place.According to a preferred embodiment, the pins connect alternately on two separate and parallel connection lines. As a variant, these connections are made regularly but not alternatively. Advantageously, the terminal strips according to the invention are produced in great length and cut to size at the time of their use. In addition, it will be noted that these bars are completely reversible. Therefore there is no preferred direction of installation which facilitates their installation.

D'autres objets, caractéristiques et avantages de la présente invention ressortiront d'ailleurs de la description qui suit, à titre d'exemple non limitatif et en référence aux dessins annexés dans lesquels:Other objects, characteristics and advantages of the present invention will emerge from the following description, by way of non-limiting example and with reference to the appended drawings in which:

- la figure 1: est une vue schématique en perspective montrant une barrette selon l'invention;- Figure 1: is a schematic perspective view showing a bar according to the invention;

- la figure 2: est une vue en plan de la barrette représentée à la figure 1 , etFIG. 2: is a plan view of the bar shown in FIG. 1, and

- la figure 3 est une vue schématique en coupe selon la ligne lll-lll de la figure 2.- Figure 3 is a schematic sectional view along the line III-III of Figure 2.

Selon la forme de réalisation représentée aux figures 1 à 3 une barrette d'interconnexion 10 est constituée par un support 11 logeant une pluralité de broches conductrices 12, dans des logements 13 prévus à cet effet. Chaque broche présente une forme générale en U et chaque extrémité 14 de cette broche est adaptée pour s'insérer dans un orifice de réception 15 (figure 3) correspondant percé dans un circuit imprimé 16, 17.According to the embodiment shown in Figures 1 to 3 an interconnection strip 10 is constituted by a support 11 housing a plurality of conductive pins 12, in housings 13 provided for this purpose. Each pin has a general U-shape and each end 14 of this pin is adapted to fit into a corresponding receiving orifice 15 (FIG. 3) drilled in a printed circuit 16, 17.

Les extrémités des broches destinées à être connectées avec un même circuit imprimé (par exemple toutes les extrémités 14 situées à droite sur la figure 3) se connectent avec le circuit imprimé 16 selon deux droites de connexion A et B, parallèles et distinctes. Bien sûr, il en est de même pour les extrémités 14 à gauche sur la figure 3, qui se connectent quant à elles au circuit imprimé 17 selon deux droites A et B. On remarque que les extrémités 14., et 142 (figure 2) de deux broches adjacentes sont connectées chacune sur une droite A ou B différente. Ainsi en décalant alternativement (une fois sur la droite A, une fois sur la droite B) les points de connexions des broches avec le circuit imprimé, on évite de créer une ligne de rupture dans le circuit imprimé au niveau de la zone de connexion. En variante les connexions entre l'extrémité des broches et le circuit imprimé sont réalisées non pas alternativement mais régulièrement sur chacune des lignes de connexions. Ainsi on peut avoir les trois premières broches sur une même ligne de connexion puis les deux suivantes sur une seconde ligne de connexion, et ainsi de suite. Tout type de combinaison du positionnement des connexions est possible.The ends of the pins intended to be connected with the same printed circuit (for example all the ends 14 situated on the right in FIG. 3) are connected with the printed circuit 16 according to two connection lines A and B, parallel and distinct. Of course, the same is true for the ends 14 on the left in FIG. 3, which in turn connect to the printed circuit 17 along two lines A and B. It is noted that the ends 14, and 14 2 (FIG. 2 ) of two adjacent pins are each connected on a different line A or B. Thus by alternately shifting (once on the right A, once on the right B) the points of connection of the pins with the printed circuit, one avoids creating a line of rupture in the printed circuit at the level of the connection zone. As a variant, the connections between the ends of the pins and the printed circuit are made not alternately but regularly on each of the connection lines. So we can have the first three pins on the same connection line then the next two on a second connection line, and so on. Any type of combination of connection positioning is possible.

Comme le montrent les dessins la barrette d'interconnexion selon la présente invention est entièrement réversible et est réalisée en grande longueur afin d'être découpée transversalement en fonction des besoins. Si nécessaire, c'est à dire notamment si la densité des connexions l'exige, les extrémités des broches conductrices sont connectées sur plus de deux lignes de connexion.As shown in the drawings, the interconnection strip according to the present invention is entirely reversible and is produced in great length so as to be cut transversely as required. If necessary, that is to say in particular if the density of the connections requires it, the ends of the conductive pins are connected on more than two connection lines.

On remarquera que la conception de la barrette selon l'invention permet d'utiliser des broches de dimensions identiques pour la réalisation de tous les décalages nécessaires. Avantageusement le décalage d'une extrémité d'une broche (vers la droite par exemple) provoque le décalage correspondant de l'autre extrémité de cette même broche (vers la gauche).It will be noted that the design of the bar according to the invention makes it possible to use pins of identical dimensions for producing all the necessary offsets. Advantageously, the offset of one end of a pin (to the right for example) causes the corresponding offset of the other end of this same pin (to the left).

Bien entendu la présente invention n'est pas limitée aux modes de réalisation ci dessus décrits et englobe toute variante à la portée de l'homme de l'art. Notamment il est possible de réaliser la barrette selon l'invention par tout procédé de moulage ou de surmoulage de matière plastique. Of course the present invention is not limited to the embodiments described above and encompasses any variant within the reach of ordinary skill in the art. In particular, it is possible to produce the strip according to the invention by any plastic molding or overmolding process.
