Description

L'invention concerne les connexions électriques entre un câble plat comprenant un ou plusieurs conducteurs, et un ou plusieurs connecteurs fixes. L'invention s'applique plus particulièrement aux câbles à conducteurs multiples pour réaliser des connexions volantes.The invention relates to electrical connections between a flat cable comprising one or more conductors, and one or more fixed connectors. The invention applies more particularly to cables with multiple conductors for making flying connections.

On connaît par FR-A-2 356 247 un câble plat pour connexions volantes. Comme le montre la figure 1, ces câbles plats se composent de plusieurs conducteurs métalliques 2 espacés les uns les autres. Ils sont de préférence placés en sandwich entre deux pellicules isolantes 3 et 4. Chaque conducteur 2 comprend une partie centrale flexible 5 et deux extrémités rigides 6 et 7. Ces conducteurs 2 ont des dimensions et des formes qui correspondent à l'utilisation qui doit en être fait.FR-A-2 356 247 discloses a flat cable for flying connections. As shown in Figure 1, these flat cables consist of several metal conductors 2 spaced from each other. They are preferably sandwiched between two insulating films 3 and 4. Each conductor 2 comprises a flexible central part 5 and two rigid ends 6 and 7. These conductors 2 have dimensions and shapes which correspond to the use which must be done.

Comme on peut le voir sur cette figure et la figure 2, les extrémités 6 et 7 peuvent être formées et profilées différemment en fonction de la connexion à effectuer sur un connecteur 8, 9. Ainsi, les extrémités 6 peuvent être coudées à angle droit, en vue de leur introduction dans des ouvertures 10 d'un connecteur 8 qui peut être une plaquette de circuit. Les extrémités 7 peuvent être coudées et façonnées en vue d'une connexion sur un connecteur 9 pour constituer des cuvettes de soudure 11.As can be seen in this figure and in Figure 2, the ends 6 and 7 can be formed and shaped differently depending on the connection to be made to a connector 8, 9. Thus, the ends 6 can be bent at right angles, for their introduction into openings 10 of a connector 8 which can be a circuit board. The ends 7 can be bent and shaped for a connection on a connector 9 to form solder cuvettes 11.

La flexibilité relative de la partie centrale 5 de ce câble plat permet d'assurer des connexions volantes. Par contre, ce type de câbles ne permet de réaliser des connexions que si les contacts des connecteurs sont soudés ou sertis. Il est donc nécessaire, pour obtenir un connecteur complet, de rajouter un système de connexion couplé aux câbles par soudure ou sertissage.The relative flexibility of the central part 5 of this flat cable makes it possible to provide flying connections. On the other hand, this type of cables only allows connections to be made if the connector contacts are soldered or crimped. It is therefore necessary, to obtain a complete connector, to add a connection system coupled to the cables by soldering or crimping.

Le but de l'invention est de remédier à cet inconvénient en proposant une conception différente des connexions.The object of the invention is to remedy this drawback by proposing a different design of the connections.

A cet effet, l'objet principal de l'invention est un système de connexion électrique pour un câble plat ayant une masse, et comprenant :

  • au moins un câble plat ayant une-partie centrale et deux extrémités ;
  • un connecteur sur lequel est à connecter le câble plat par sa première extrémité.
To this end, the main object of the invention is an electrical connection system for a flat cable having a mass, and comprising:
  • at least one flat cable having a central part and two ends;
  • a connector on which is to connect the flat cable by its first end.

Selon l'invention, au moins une extrémité du câble comprend :

  • une extrémité de contact conductrice de surface plate et réduite qui se trouve en position centrale par rapport à :
  • une extrémité de contact de masse en forme de couronne plate entourant l'extrémité conductrice, et laissant un espace entre elle et l'extrémité conductrice ;
  • des moyens de fixation de l'extrémité du câble sur le connecteur.
According to the invention, at least one end of the cable comprises:
  • a conductive contact end of flat and reduced surface which is in a central position with respect to:
  • a ground contact end in the form of a flat crown surrounding the conductive end, and leaving a space between it and the conductive end;
  • means for fixing the end of the cable to the connector.

L'invention s'applique particulièrement à un câble plat comprenant :

  • une masse constituée d'une lame métallique reliée à l'extrémité de masse ;
  • une partie conductrice constituée d'une lame métallique reliée à l'extrémité conductrice, ces deux lames étant séparées par un isolant.
The invention is particularly applicable to a flat cable comprising:
  • a mass consisting of a metal blade connected to the mass end;
  • a conductive part consisting of a metal strip connected to the conductive end, these two strips being separated by an insulator.

Selon une caractéristique de l'invention, les lames sont plus épaisses à leur extrémité de contact que dans la partie centrale du câble.According to a characteristic of the invention, the blades are thicker at their contact end than in the central part of the cable.

Le connecteur comprend de préférence :

  • une tige centrale avec une surface centrale de contact de forme correspondante à l'extrémité conductrice pour recevoir cette dernière ;
  • une bague extérieure avec une surface supérieure de contact de forme correspondant à l'extrémité de masse pour recevoir cette dernière ;
  • une pièce isolante séparant la tige centrale de la bague extérieure et sur laquelle sont fixées ces deux pièces.
The connector preferably includes:
  • a central rod with a central contact surface of a shape corresponding to the conductive end to receive the latter;
  • an outer ring with a shaped upper contact surface corresponding to the earth end to receive the latter;
  • an insulating part separating the central rod from the outer ring and on which these two parts are fixed.

Dans ce cas, les moyens de fixation comprennent :

  • une cavité torique de forme déterminée, constituée de la bague extérieure, de la tige centrale et de la pièce isolante, avec une dépouille pour permettre l'introduction d'une pièce ;
  • une capsule surmoulée possédant sur un côté les formes complémentaires à celles de la cavité torique du connecteur et des bords entourant la bague extérieure, de façon à pouvoir être fixée sur le connecteur par une simple pression et fixer le câble sur le connecteur. De cette manière, quelle que soit l'orientation possible du câble, il est possible à un opérateur d'effectuer la fixation sans même regarder l'opération qu'il effectue.
In this case, the fixing means include:
  • a toroidal cavity of determined shape, consisting of the outer ring, the central rod and the insulating part, with a draft to allow the introduction of a part;
  • a molded capsule having on one side the shapes complementary to those of the toric cavity of the connector and of the edges surrounding the outer ring, so that it can be fixed on the connector by a simple pressure and fix the cable on the connector. In this way, whatever the possible orientation of the cable, it is possible for an operator to carry out the fixing without even looking at the operation which he performs.

L'invention et ses différentes caractéristiques seront mieux décrites à la lecture de la description suivante, annexée de différentes figures représentant respectivement :

  • figure 1, un câble plat selon une réalisation de l'art antérieur ;
  • figure 2, le même câble plat de l'art antérieur en vue de profil, ces deux premières figures ayant déjà été décrites ;
  • figure 3, une extrémité d'un câble plat selon l'invention ;
  • figure 4, en coupe frontale, le système de connexion selon l'invention.
The invention and its various characteristics will be better described on reading the following description, appended to various figures representing respectively:
  • Figure 1, a flat cable according to an embodiment of the prior art;
  • Figure 2, the same flat cable of the prior art in profile view, these first two figures having already been described;
  • Figure 3, one end of a flat cable according to the invention;
  • Figure 4, in front section, the connection system according to the invention.

L'extrémité du câble plat 1 représentée par la figure 3 comprend principalement trois éléments : un conducteur de courant métallique 12, un conducteur de masse métallique 14 et un isolant 13.The end of the flat cable 1 represented by FIG. 3 mainly comprises three elements: a metallic current conductor 12, a metallic ground conductor 14 and an insulator 13.

Le conducteur de courant métallique 12 est une lame métallique dont l'extrémité 12A est rétrécie pour constituer une petite surface de contact, par exemple ronde. Cette forme est un exemple de réalisation mais n'a aucune importance fonctionnelle.The metal current conductor 12 is a metal strip whose end 12A is narrowed to form a small contact surface, for example round. This form is an exemplary embodiment but has no functional importance.

Le conducteur de masse 14 est une lame métallique dont l'extrémité 14A entoure l'extrémité 12A du conducteur 12, tout en ménageant un espace entre ces deux éléments, de manière à ce qu'il n'y ait pas de contact possible entre les deux extrémités.The ground conductor 14 is a metal strip whose end 14A surrounds the end 12A of the conductor 12, while leaving a space between these two elements, so that there is no possible contact between the two ends.

La figure 4 permet de mieux voir la structure du câble plat 1 selon l'invention. En fait, le conducteur de courant 12 et le conducteur de masse 14 sont deux lames métalliques superposées. Ces deux lames sont séparées par un isolant 13. De préférence, on place également deux isolants autour de ces deux éléments, de manière à les entourer. L'isolant est absent de l'extrémité 12A du conducteur de courant 12 et de l'extrémité 14A du conducteur de masse 14, de manière à permettre le contact de ces deux éléments avec un connecteur.Figure 4 provides a better view of the structure of the flat cable 1 according to the invention. In fact, the current conductor 12 and the ground conductor 14 are two superimposed metal blades. These two blades are separated by an insulator 13. Preferably, two insulators are also placed around these two elements, so as to surround them. The insulator is absent from the end 12A of the current conductor 12 and from the end 14A of the ground conductor 14, so as to allow contact of these two elements with a connector.

Les extrémités de contact conductrice 12A et de masse 14A ont été placées dans le prolongement de leur lame métallique respective 12 et 14. Ceci n'est qu'une forme de réalisation, la position verticale de ces deux extrémités 12A et 14A pouvant être modifiée en fonction de la configuration du connecteur et de la capsule.The conductive contact ends 12A and earth 14A have been placed in the extension of their respective metal strip 12 and 14. This is only one embodiment, the vertical position of these two ends 12A and 14A can be modified in depending on the configuration of the connector and the capsule.

On note également qu'il est préférable que ces extrémités 12A et 14A soit plus épaisses que leurs lames métalliques respectives 12 et 14 de la partie centrale du câble plat.We also note that it is preferable that these ends 12A and 14A be thicker than their respective metal blades 12 and 14 of the central part of the flat cable.

En référence à la figure 4, le connecteur se compose de préférence d'une tige centrale 15, d'une bague extérieure 16 et d'un isolant 17.With reference to FIG. 4, the connector preferably consists of a central rod 15, an outer ring 16 and an insulator 17.

La tige centrale 15 est centrée au milieu du connecteur, le long d'un axe vertical 18 de ce dernier. Elle est terminée à son extrémité supérieure par une surface de contact 15A destinée à recevoir l'extrémité de contact conductrice 12A du câble. Sa forme correspond de préférence à la forme de cette extrémité de contact conductrice 12A.The central rod 15 is centered in the middle of the connector, along a vertical axis 18 of the latter. It is terminated at its upper end by a contact surface 15A intended to receive the conductive contact end 12A of the cable. Its shape preferably corresponds to the shape of this conductive contact end 12A.

De manière analogue, la bague extérieure 16 est terminée à son extrémité supérieure par une surface de contact 16A en forme de couronne, correspondant à la forme de l'extrémité de contact de masse 14A. Les positions verticales respectives des surfaces de contact 15A et 16A sont en correspondance avec les positions verticales respectives des extrémités de contact conductrices 12A et de masse 14A du câble plat 1.Similarly, the outer ring 16 is terminated at its upper end by a contact surface 16A in the form of a crown, corresponding to the shape of the ground contact end 14A. The respective vertical positions of the contact surfaces 15A and 16A correspond to the respective vertical positions of the conductive contact ends 12A and of ground 14A of the flat cable 1.

L'isolant 17 est destiné à maintenir espacées l'une de l'autre la tige centrale 15 et la bague extérieure 16. Néanmoins, dans sa partie supérieure, cette pièce isolante 17 a une forme telle qu'elle permet de définir, à l'aide de la tige centrale 15 et de la bague extérieure 16, une cavité 17A séparant d'une manière conséquente les surfaces de contact 15A et 16A.The insulator 17 is intended to keep the central rod 15 and the outer ring 16 spaced from one another. However, in its upper part, this insulating part 17 has a shape such that it makes it possible to define, at the 'Using the central rod 15 and the outer ring 16, a cavity 17A substantially separating the contact surfaces 15A and 16A.

L'ensemble de ce connecteur est fixé sur une paroi d'équipement 19, grâce par exemple à la forme extérieure de la bague extérieure. Cette fixation peut se faire par soudure.The whole of this connector is fixed to an equipment wall 19, for example thanks to the external shape of the outer ring. This fixing can be done by welding.

La figure 4 représente également une capsule 21, de préférence surmoulée, dont la forme de la surface inférieure correspond à la forme supérieure du connecteur 20. En d'autres termes, cette forme, constituée des parties proéminentes annulaires 22 et 23, est complémentaire à celle du connecteur 20 et notamment à la forme définie par les surfaces de contact 15A et 16A et par la cavité 17A.FIG. 4 also represents a capsule 21, preferably overmolded, the shape of the lower surface of which corresponds to the upper shape of the connector 20. In other words, this shape, made up of the annular prominent parts 22 and 23, is complementary to that of the connector 20 and in particular to the shape defined by the contact surfaces 15A and 16A and by the cavity 17A.

La capsule surmoulée 21 est bien entendu destinée à être fixée sur le connecteur 20 par introduction des parties proéminentes 22 et 23 dans la cavité 17A du connecteur 20 et autour de ce dernier. Pour permettre cette pénétration et le maintien de la capsule 21 sur le connecteur 20, celle-ci est prévue en une matière plastique légèrement déformable. Le matériau constitutif de la capsule peut être du type élastomère par exemple. Le surmoulage se fait directement sur l'extrémité du câble plat 1 ou sur un modèle de forme identique. De plus, la forme des parties qui pénètre sur le connecteur 20 est telle qu'il existe une légère dépouille sur les parois latérales de ces parties 22 et 23 pour permettre l'introduction de la capsule 21 sur le connecteur 20. En correspondance, la cavité 17A et la surface extérieure 20A supérieure du connecteur 20 sont également légèrement inclinées en correspondance avec l'inclinaison des formes de la capsule 21 pour permettre la pénétration de la capsule 21 sur le connecteur 20. Ceci n'est qu'un exemple de réalisation, le principe de la fixation de la capsule 21 sur le connecteur 20 étant un verrouillage élastique, de préférence par emmanchement conique, comme celui par exemple des capsules de bouteilles d'eau minérale.The overmolded capsule 21 is of course intended to be fixed to the connector 20 by introduction of the protruding parts 22 and 23 into the cavity 17A of the connector 20 and around the latter. To allow this penetration and the maintenance of the capsule 21 on the connector 20, it is provided in a slightly deformable plastic. The constituent material of the capsule can be of the elastomer type for example. Overmolding is done directly on the end of the flat cable 1 or on a model of identical shape. In addition, the shape of the parts which penetrates the connector 20 is such that there is a slight draft on the side walls of these parts 22 and 23 to allow the introduction of the capsule 21 on the connector 20. In correspondence, the cavity 17A and the upper external surface 20A of the connector 20 are also slightly inclined in correspondence with the inclination of the shapes of the capsule 21 to allow the penetration of the capsule 21 on the connector 20. This is only an exemplary embodiment , the principle of fixing the capsule 21 on the connector 20 being an elastic locking, preferably by conical fitting, like that for example of bottles of mineral water bottles.

Pour permettre au câble plat 1 d'accéder au milieu de la capsule 21, la paroi extérieure 22 de la capsule 21 est échancrée sur une largeur équivalente à la largeur du câble plat 1. Il en est de même pour la partie intérieure 23 qui est échancrée sur la largeur relativement faible de la lame métallique reliant la partie centrale du conducteur 12 avec son extrémité de contact 12A.To allow the flat cable 1 to access the middle of the capsule 21, the outer wall 22 of the capsule 21 is indented over a width equivalent to the width of the flat cable 1. It is the same for the inner part 23 which is indented over the relatively small width of the metal strip connecting the central part of the conductor 12 with its contact end 12A.

La figure 4 montre le montage de l'ensemble, une fois que le câble 1 est fixé sur le connecteur 20 au moyen de la capsule 21. On voit que cette dernière est enfoncée entièrement sur le connecteur 20, la partie intérieure 23 de la capsule 21 pénétrant dans la cavité 17A, la partie extérieure 22 de la capsule 21 entourant la surface extérieure 16A de la bague 16. Ainsi, le câble plat 1 est en contact, par son extrémité de contact conductrice 12A sur la surface de contact 15A de la tige centrale 15 et par son extrémité de contact de masse 14A sur la surface supérieure 16A de la bague 16.FIG. 4 shows the assembly of the assembly, once the cable 1 is fixed to the connector 20 by means of the capsule 21. It can be seen that the latter is pressed entirely onto the connector 20, the inner part 23 of the capsule 21 penetrating into the cavity 17A, the outer part 22 of the capsule 21 surrounding the outer surface 16A of the ring 16. Thus, the flat cable 1 is in contact, by its conductive contact end 12A on the contact surface 15A of the central rod 15 and by its earth contact end 14A on the upper surface 16A of the ring 16.

La conception de ce type de connexion électrique apporte certains avantages.The design of this type of electrical connection brings certain advantages.

Aucune visserie, ni soudure, n'est utilisée pour réaliser La connexion et la fixation du câble plat 1 sur le connecteur 20.No screws or soldering is used to make the connection and fixing of the flat cable 1 on the connector 20.

La partie conductrice 12 et son extrémité de contact 12A d'une part, et la partie de masse 14 et son extrémité de contact 14A d'autre part, sont réalisées de façon monolithique.The conductive part 12 and its contact end 12A on the one hand, and the ground part 14 and its contact end 14A on the other hand, are produced in a monolithic manner.

Dans la réalisation représentée sur les figures, les connexions sont effectuées dans le même plan que la nappe de fil, c'est-à-dire dans les mêmes plans respectifs des lames constituant la partie conductrice 12 et la partie de masse 14, ceci diminue l'encombrement de la connexion.In the embodiment shown in the figures, the connections are made in the same plane as the wire ply, that is to say in the same respective planes of the blades constituting the conductive part 12 and the ground part 14, this decreases the size of the connection.

Le verrouillage par enfichage élastique de la capsule 21 permet d'effectuer une connexion "à l'aveugle", c'est-à-dire que l'opérateur n'est pas obligé de regarder l'opération qu'il est en train d'effectuer. Ceci facilite la réalisation de la connexion.Locking by elastic plugging of the capsule 21 makes it possible to make a "blind" connection, that is to say that the operator is not obliged to watch the operation which he is in the process of carrying out. 'carry out. This facilitates the making of the connection.

L'orientation du câble plat 1 sur le connecteur 20 peut être quelconque, c'est-à-dire que le câble plat peut être positionné sur 360°.The orientation of the flat cable 1 on the connector 20 can be arbitrary, that is to say that the flat cable can be positioned over 360 °.

Le contact par appui effectué par la capsule 21 offre un effet de ressort sur l'extrémité de contact conductrice centrale 12A, ce qui assure une bonne tenue de la connexion vis-à-vis des vibrations.The contact made by the capsule 21 provides a spring effect on the central conductive contact end 12A, which ensures good resistance of the connection to vibrations.

La capsule surmoulée 21 permet d'allonger les lignes de fuites haute tension, afin d'obtenir une tenue diélectrique acceptable à des tensions supérieures à 2 kV.The overmolded capsule 21 makes it possible to lengthen the high voltage leakage lines, in order to obtain an acceptable dielectric strength at voltages greater than 2 kV.

La capsule 21 contribue largement à la tenue mécanique de l'ensemble de la connexion.The capsule 21 largely contributes to the mechanical strength of the entire connection.

On a donc réalisé par le système de connexion selon l'invention une connexion haute tension simple, fiable, sans câblage, dans un très faible encombrement et permettant une connexion à l'aveugle.The connection system according to the invention therefore provides a simple, reliable high voltage connection, without wiring, in a very small footprint and allowing connection to the blind.

L'invention peut s'appliquer aux connexions haute tension en environnement sévère et aux connexions basse tension avec ou sans blindage.The invention can be applied to high voltage connections in harsh environments and to low voltage connections with or without shielding.
