Description

La présente invention concerne un système de connexion pour cartes à circuits imprimés et, en particulier, un système de connexion sans soudure entre des cartes électroniques et des dispositifs externes par l'intermédiaire de bornes de connexion perpendiculaires à la carte.The present invention relates to a connection system for printed circuit boards and, in particular, a seamless connection system between electronic boards and external devices via connection terminals perpendicular to the board.

Un système de connexion selon le préambule de la revendication 1 est connu du document FR 2.115.712 .A connection system according to the preamble of claim 1 is known from the document FR 2.115.712 .

Le problème de la connexion des circuits électroniques d'une carte à circuit imprimé avec des dispositifs externes à celle-ci est traditionnellement résolu par l'intermédiaire de connecteurs qui présentent une rangée de conducteurs ou de broches de connexion à lamelles ou à fiches parallèles, ayant une première de leurs extrémités disposée en contact avec les bornes de connexion d'une piste conductrice respective de la carte et l'autre extrémité orientée à l'extérieur de la carte, pour la connexion à une plaque à bornes d'un dispositif externe.The problem of connecting the electronic circuits of a printed circuit board with devices external thereto is traditionally solved by means of connectors having a row of conductors or connection pins with lamellae or parallel plugs, having one end thereof disposed in contact with the connecting terminals of a respective conductive track of the board and the other end facing outboard of the board for connection to a terminal board of an external device .

Dans la connexion sur carte par l'intermédiaire de bornes orthogonales au plan de la carte, que soient utilisés des connecteurs dans lesquels les conducteurs traversent de part en part la carte à travers des trous métallisés ou des connecteurs CMS repliés, afin de garantir la connexion dans le temps, les connecteurs sont soudés en contact avec les bornes de connexion d'une piste conductrice respective de la carte.In the board connection via terminals orthogonal to the plane of the board, whether connectors are used in which the conductors pass right through the board through metallized holes or folded-in CMS connectors, in order to guarantee the connection in time, the connectors are soldered in contact with the connection terminals of a respective conductive track of the card.

En variante, les bornes d'un circuit externe peuvent être directement insérées par pression dans les trous métallisés de la carte suivant la technique connue sous le nom de "pressfit" (à ajustement serré).Alternatively, the terminals of an external circuit can be directly inserted by pressure into the metallized holes of the card according to the technique known as "pressfit" (tight fit).

Ces solutions de fixation empêchent cependant la possibilité de démonter l'ensemble et de remplacer les dispositifs reliés à la carte. Le montage automatique des connecteurs est en outre ralenti par l'opération de soudure finale dans la plus grande partie des cas.These fixing solutions, however, prevent the possibility of disassembling the assembly and replace the devices connected to the card. The automatic assembly of the connectors is also slowed down by the final welding operation in most cases.

Un but de la présente invention est de fournir un système de connexion électrique alternatif pour la connexion d'une carte à circuits imprimés avec un dispositif ou circuit externe par l'intermédiaire de bornes perpendiculaires à la carte, qui rende possible le démontage pour un remplacement successif et, en même temps, s'avère économique par rapport à la technique connue.An object of the present invention is to provide an alternative electrical connection system for connecting a printed circuit board with an external device or circuit via terminals perpendicular to the board, which makes disassembly possible for replacement. successively and, at the same time, proves to be economical with respect to the known technique.

Dans ce but, un objet de l'invention est formé par un système de connexion selon la revendication 1.For this purpose, an object of the invention is formed by a connection system according to claim 1.

Des modes particuliers de réalisations de l'invention sont définis.Particular embodiments of the invention are defined.

Des avantages et caractéristiques de la présente invention ressortiront de la description détaillée ci-après, faite en référence aux figures 1 et 2 annexées, données uniquement à titre d'exemple non limitatif, dans lesquelles est illustré le système de connexion faisant l'objet de l'invention.Advantages and features of the present invention will emerge from the following detailed description, made with reference to figures 1 and 2 annexed, given only to As a non-limiting example, in which is illustrated the connection system subject of the invention.

Sur les figures est représentée, dans une condition de fonctionnement, une carte à circuit imprimé 12 à laquelle est connecté un dispositif externe 14 (représenté en trait interrompu) par l'intermédiaire d'une paire de bornes conductrices lamellaires 16 s'étendant dans une direction sensiblement orthogonale au plan de la carte.In the figures is shown, in an operating condition, a printed circuit board 12 to which is connected an external device 14 (shown in broken lines) via a pair of lamellar conductive terminals 16 extending in a direction substantially orthogonal to the plane of the map.

Lesdites bornes de connexion ont une section rectangulaire ou une section quelconque.Said connection terminals have a rectangular section or any section.

La carte 12 présente un groupe connecteur 20 formé par un corps 22 fixé sur la surface de la carte orientée vers le dispositif à connecter et comportant une paire d'éléments conducteurs de contact 24 en saillie, disposés sensiblement dans une direction perpendiculaire au plan de la carte.The card 12 has a connector group 20 formed by a body 22 fixed on the surface of the card facing the device to be connected and having a pair of protruding conductive contact elements 24 arranged substantially in a direction perpendicular to the plane of the map.

Les bornes conductrices de connexion 16 du dispositif présentent à leurs extrémités de contact des conformations respectives à griffe 30 qui définissent chacune une paire de fourchons 32 déformables de manière élastique durant la prise des éléments conducteurs de contact 24 solidaires de la carte.The conductive connection terminals 16 of the device have, at their contact ends, respective claw conformations 30 which each define a pair of elastically deformable prongs 32 during setting of the conductive contact elements 24 integral with the card.

Les bornes sont réalisés - par exemple - par une simple opération de découpe d'une feuille métallique et les fourchons des griffes se trouvent dans un plan.The terminals are made - for example - by a simple operation of cutting a metal sheet and the claws of the claws are in a plane.

Dans la configuration préférée représentée sur la figure 1, les bornes 16 présentent un segment principal 40 sensiblement coaxial avec un élément de contact 24 présenté de la carte, un segment intermédiaire 42 plié à 90 degrés par rapport au segment principal et un segment d'extrémité 44 replié de 180 degrés par rapport au segment intermédiaire de manière à définir avec celui-ci une conformation en U dans un plan général de la borne conductrice.In the preferred configuration shown on the figure 1 , the terminals 16 have a main segment 40 substantially coaxial with a contact element 24 presented on the card, an intermediate segment 42 bent at 90 degrees with respect to the main segment and an end segment 44 folded 180 degrees relative to the intermediate segment so as to define therewith a U-shaped in a general plane of the conductive terminal.

Comme référencée à la figure 2, le segment 42 illustré dans la figure 1 peut être supprimé de telle manière à définir une conformation en L plus or moins obtus ou plus or moins aigus, dans un plan général de la borne conductrice.As referenced to figure 2 , the segment 42 illustrated in the figure 1 can be removed in such a way as to define a conformation in L plus or minus obtuse or more or less acute, in a general plane of the conductive terminal.

Le segment d'extrémité 44 se trouve dans un plan parallèle au, plan de la carte 12 et comporte à l'extrémité libre ladite conformation à griffe 30 pour la prise d'un élément conducteur 24 respectif.The end segment 44 is in a plane parallel to the plane of the card 12 and comprises at the free end said claw conformation 30 for the gripping of a respective conductive element 24.

D'après ce qui précède, les avantages du système de connexion pour cartes à circuits imprimés selon l'invention sont évidents.From the foregoing, the advantages of the printed circuit board connection system according to the invention are obvious.

La réalisation de la connexion est très simplifiée, du fait que le nombre de parties constituantes nécessaires est limité, mais, en même temps, un contact optimal est garanti, en mesure de supporter le passage de courants d'intensité élevée. Il est en outre possible d'automatiser le positionnement des différents composants du système. La connexion électrique d'une carte sur les bornes de connexion d'un dispositif externe s'effectue par translation dans un axe perpendiculaire au plan défini par la rangée des bornes, c'est à dire parallèle au plan de la carte.The realization of the connection is very simplified, because the number of necessary constituent parts is limited, but, at the same time, an optimal contact is guaranteed, able to withstand the passage of currents of high intensity. It is also possible to automate the positioning of the various components of the system. The electrical connection of a card to the connection terminals of an external device is performed by translation in an axis perpendicular to the plane defined by the row of terminals, ie parallel to the plane of the card.

Le système rend possible de manière aisée et rapide la séparation du dispositif 14 de la carte 12 pour un éventuel remplacement.The system makes it easy and quick to separate the device 14 from the card 12 for possible replacement.

Naturellement, tout en maintenant le principe de l'invention, les formes de mise en oeuvre et les détails de réalisation pourront être largement modifiés, sans pour autant sortir de l'étendue de protection de la présente invention telle qu'elle est définie.Naturally, while maintaining the principle of the invention, the forms of implementation and the details of implementation may be widely modified, without departing from the scope of protection of the present invention as defined.
