Description

La présente invention concerne un connecteur électrique, notamment pour une prise électrique, comprenant un dispositif détrompeur modulable.The present invention relates to an electrical connector, in particular for an electrical outlet, comprising a modular keying device.

Une prise électrique comprend généralement un premier connecteur électrique, formant une embase, et un second connecteur électrique, formant une fiche, destinés à être rapprochés l'un de l'autre le long d'une direction d'enfichage jusqu'à être enfichés, pour ainsi réaliser une connexion électrique.An electrical outlet generally comprises a first electrical connector, forming a base, and a second electrical connector, forming a plug, intended to be brought closer to one another along a plug-in direction until they are plugged in, to make an electrical connection.

Il est connu d'utiliser des dispositifs détrompeurs, également appelés dispositifs de codage, permettant d'éviter à un utilisateur de connecter une fiche et une embase incompatibles entre elles, ou bien compatibles entre elles mais reliées à deux appareils électriques incompatibles entre eux.It is known to use polarizing devices, also called coding devices, to prevent a user from connecting a plug and a base incompatible with each other, or compatible with each other but connected to two electrical devices incompatible with each other.

A cet effet, un dispositif détrompeur comprend généralement au moins un premier élément détrompeur fixé sur la fiche, et au moins un second élément détrompeur fixé sur l'embase et destiné à coopérer avec le premier élément détrompeur. On assure ainsi que, parmi une série de fiches et d'embases disponibles pour un utilisateur et d'aspect semblable, uniquement certaines fiches et certaines embases présélectionnées, et dites « complémentaires », puissent être effectivement connectées les unes aux autres.For this purpose, a polarizing device generally comprises at least one first polarizing element fixed on the plug, and at least one second polarizing element fixed on the base and intended to cooperate with the first polarizing element. This ensures that among a series of plugs and bases available to a user and similar appearance, only certain plugs and preselected bases, and said "complementary", can be effectively connected to each other.

Dans de tels dispositifs détrompeurs connus, les éléments détrompeurs sont portés à demeure sur les connecteurs électriques, ce qui impose à un opérateur réalisant des circuits électriques d'effectuer une gestion de l'approvisionnement de connecteurs munis de différents dispositifs détrompeurs, dits « connecteurs codés ». En outre, le fabricant de connecteurs doit prévoir la réalisation d'une multitude de connecteurs électriques comportant des éléments détrompeurs agencés différemment.In such known polarizing devices, the polarizing elements are permanently attached to the electrical connectors, which requires an operator of electrical circuits to perform a supply management of connectors provided with different polarizing devices, called "coded connectors". ". In addition, the connector manufacturer must provide for the realization of a multitude of electrical connectors comprising polarizing elements arranged differently.

L'invention a notamment pour but de remédier à ces inconvénients, en fournissant un connecteur électrique comprenant un dispositif détrompeur modulable.The object of the invention is in particular to remedy these drawbacks by providing an electrical connector comprising a modular coding device.

A cet effet, l'invention a notamment pour objet un connecteur, notamment de prise électrique, présentant une paroi cylindrique de réception d'un organe complémentaire, s'étendant le long d'un axe longitudinal, caractérisé en ce que :

  • ladite paroi de réception est munie d'au moins deux rainures longitudinales s'étendant parallèlement à l'axe longitudinal, et
  • le connecteur comporte au moins un élément détrompeur, logé dans l'une des rainures longitudinales.
For this purpose, the invention particularly relates to a connector, in particular an electrical connector, having a cylindrical wall for receiving a complementary member, extending along a longitudinal axis, characterized in that:
  • said receiving wall is provided with at least two longitudinal grooves extending parallel to the longitudinal axis, and
  • the connector comprises at least one polarizing element, housed in one of the longitudinal grooves.

Un ou plusieurs éléments détrompeurs peuvent être logés indifféremment dans l'une quelconque des rainures longitudinales, si bien qu'un opérateur réalisant un circuit électrique peut réaliser lui-même le codage des connecteurs électriques, sans avoir à gérer l'approvisionnement de connecteurs codés.One or more polarizing elements can be housed indifferently in any of the longitudinal grooves, so that an operator performing a circuit electrical can itself perform the coding of electrical connectors, without having to manage the supply of coded connectors.

En outre, les connecteurs selon l'invention sont standardisés, puisqu'ils ne comportent que des rainures longitudinales, agencées de manière identique. Ainsi, le fabriquant ne nécessite plus que de concevoir un seul type de connecteur, comprenant ces rainures longitudinales, et les éléments détrompeurs permettant de réaliser le codage.In addition, the connectors according to the invention are standardized, since they comprise only longitudinal grooves, arranged identically. Thus, the manufacturer no longer needs to design a single type of connector, including these longitudinal grooves, and the keying elements to perform the coding.

L'invention sera mieux comprise à la lecture de la description qui va suivre, donnée uniquement à titre d'exemple et faite en se référant aux figures annexées, parmi lesquelles :

  • la figure 1 est une vue en perspective d'un connecteur électrique selon un exemple de mode de réalisation de l'invention ;
  • la figure 2 est une vue en perspective d'un élément détrompeur équipant le connecteur électrique de la figure 1.
The invention will be better understood on reading the description which follows, given solely by way of example and with reference to the appended figures, among which:
  • the figure 1 is a perspective view of an electrical connector according to an exemplary embodiment of the invention;
  • the figure 2 is a perspective view of a polarizing element equipping the electrical connector of the figure 1 .

On a représenté, sur la figure 1, un connecteur électrique 10, notamment pour une prise électrique. Plus particulièrement, dans l'exemple représenté, le connecteur électrique 10 est une embase de prise électrique.On the figure 1 , an electrical connector 10, in particular for an electrical outlet. More particularly, in the example shown, the electrical connector 10 is a socket base.

Seule une partie isolante du connecteur électrique 10 est représentée, la partie de connexion électrique proprement dite pouvant être de tout type envisageable.Only an insulating portion of the electrical connector 10 is shown, the actual electrical connection portion can be of any type possible.

Le connecteur électrique 10 présente une paroi cylindrique 12 de réception d'un organe électrique complémentaire (non représenté). En particulier, lorsque le connecteur électrique 10 est une embase de prise électrique, l'organe électrique complémentaire est une fiche de prise électrique. En variante, dans le cas où le connecteur électrique est une fiche, l'organe électrique complémentaire est alors une embase de prise électrique.The electrical connector 10 has a cylindrical wall 12 for receiving a complementary electrical member (not shown). In particular, when the electrical connector 10 is a socket base, the complementary electrical member is a plug socket. Alternatively, in the case where the electrical connector is a plug, the complementary electrical member is then a socket base.

Dans l'exemple représenté, où le connecteur 10 est une embase de prise électrique, ladite paroi cylindrique 12 est une paroi intérieure, délimitant un espace de réception pour la fiche de prise. En variante, dans le cas où le connecteur 10 est une prise, la paroi cylindrique 12 est une paroi extérieure.In the example shown, where the connector 10 is an electrical socket, said cylindrical wall 12 is an inner wall, defining a receiving space for the plug. Alternatively, in the case where the connector 10 is a socket, the cylindrical wall 12 is an outer wall.

Dans tous les cas, la paroi cylindrique 12 s'étend le long d'un axe longitudinal X, définissant une direction d'enfichage du connecteur électrique 10 avec l'organe électrique complémentaire.In all cases, the cylindrical wall 12 extends along a longitudinal axis X, defining a direction of insertion of the electrical connector 10 with the complementary electrical member.

La paroi de réception 12 est munie d'au moins deux rainures longitudinales 14, par exemple trois rainures longitudinales, chaque rainure longitudinale 14 s'étendant parallèlement audit axe longitudinal X.The receiving wall 12 is provided with at least two longitudinal grooves 14, for example three longitudinal grooves, each longitudinal groove 14 extending parallel to said longitudinal axis X.

Avantageusement, la distance circonférentielle entre deux rainures longitudinales 14 circonférentiellement adjacentes n'est pas constante. Ainsi, dans l'exemple représenté, les trois rainures 14 sont disposées dans une seule moitié circonférentielle de la paroi cylindrique, l'autre moitié étant dépourvue de rainure. Ainsi, quel que soit le codage choisi, comme cela sera décrit ultérieurement, l'orientation angulaire du connecteur électrique 10 par rapport à l'organe électrique complémentaire est prédéfinie par la position des rainures 14.Advantageously, the circumferential distance between two circumferentially adjacent longitudinal grooves 14 is not constant. Thus, in the example shown, the three grooves 14 are disposed in a single circumferential half of the cylindrical wall, the other half being devoid of a groove. Thus, whatever the coding chosen, as will be described later, the angular orientation of the electrical connector 10 with respect to the complementary electrical member is predefined by the position of the grooves 14.

Le connecteur 10 comporte par ailleurs au moins un élément détrompeur 16, par exemple deux éléments détrompeurs 16, permettant de réaliser le codage de ce connecteur.The connector 10 furthermore comprises at least one polarizing element 16, for example two polarizing elements 16, making it possible to carry out the coding of this connector.

Chaque élément détrompeur 16 est propre à être inséré, de préférence de manière amovible, dans l'une quelconque des rainures longitudinales 14. Ainsi, toutes les rainures longitudinales 14 sont sensiblement identiques, de forme et de dimensions complémentaires de celles des éléments détrompeurs 16. De même, tous les éléments détrompeurs 16 sont sensiblement identiques.Each polarizing element 16 is adapted to be inserted, preferably removably, in any one of the longitudinal grooves 14. Thus, all the longitudinal grooves 14 are substantially identical, of shape and of dimensions complementary to those of the polarizing elements 16. Likewise, all the polarizing elements 16 are substantially identical.

Plus particulièrement, chaque rainure 14 comporte par exemple une partie formant rail 14A, permettant notamment de guider un élément détrompeur 16 lorsqu'il est inséré dans cette rainure 14. La partie formant rail 14A présente une surface de fond 15 et deux premières surfaces latérales 17 convergeant l'une vers l'autre depuis la surface de fond 15 jusqu'à des extrémités libres respectives. Ainsi, ces premières surfaces longitudinales 17 sont tournées vers la surface de fond 15, si bien que l'élément détrompeur 16 peut être maintenu dans la rainure 14 radialement entre la surface de fond 15 et les premières surfaces latérales 17.More particularly, each groove 14 comprises for example a rail portion 14A, in particular for guiding a polarizing element 16 when it is inserted in this groove 14. The rail portion 14A has a bottom surface 15 and two first side surfaces 17 converging towards each other from the bottom surface 15 to respective free ends. Thus, these first longitudinal surfaces 17 are turned towards the bottom surface 15, so that the polarizing element 16 can be held in the groove 14 radially between the bottom surface 15 and the first lateral surfaces 17.

Chaque rainure 14 comporte par ailleurs une partie de coincement 14B, comprenant également une surface de fond, par exemple prolongeant la surface de fond 15 de la partie formant rail 14A, et deux secondes surfaces latérales 19 sensiblement parallèles entre elles. Ces secondes surfaces latérales 19 sont par exemple chacune agencée dans le prolongement, dans la direction de l'axe longitudinal X, de l'extrémité libre de l'une respective des premières surfaces latérales 17.Each groove 14 further comprises a wedging portion 14B, also comprising a bottom surface, for example extending the bottom surface 15 of the rail portion 14A, and two second side surfaces 19 substantially parallel to each other. These second lateral surfaces 19 are for example each arranged in the extension, in the direction of the longitudinal axis X, of the free end of a respective one of the first lateral surfaces 17.

On notera que la partie formant rail 14A et la partie de coincement 14B de chacune rainure 14 sont alignées dans la direction de l'axe longitudinal X, de sorte que l'élément détrompeur 16 inséré dans la rainure 14 passe par la partie formant rail 14A avant de parvenir à la partie de coincement 14B.Note that the rail portion 14A and the wedging portion 14B of each groove 14 are aligned in the direction of the longitudinal axis X, so that the keying member 16 inserted into the groove 14 passes through the rail portion 14A. before reaching the cornering portion 14B.

Les premières surfaces latérales 17 étant inclinées, alors que les secondes surfaces latérales 19 sont parallèles entre elles, un épaulement 21 est défini entre chaque première surface latérale 17 et seconde surface latérale 19 correspondante.The first side surfaces 17 being inclined, while the second side surfaces 19 are parallel to each other, a shoulder 21 is defined between each first side surface 17 and corresponding second side surface 19.

Par ailleurs, chaque élément détrompeur 16 présente une forme adaptée pour coopérer avec de telles rainures longitudinales 14. Un élément détrompeur 16 a été représenté sur la figure 2.Furthermore, each polarizing element 16 has a shape adapted to cooperate with such longitudinal grooves 14. A polarizing element 16 has been represented on the figure 2 .

Chaque élément détrompeur 16 comporte une partie de liaison 16A, comprenant une surface arrière 18 et deux surfaces latérales 20 convergeant l'une vers l'autre depuis la surface arrière 18 jusqu'à une surface avant 22. Cette partie de liaison 16A présente une forme et des dimensions complémentaires à celles de la partie formant rail 14A de chaque rainure 14, de sorte que cette partie de liaison 16A peut être maintenue radialement entre la surface de fond et les premières surfaces latérales de la partie formant rail 14A lorsque cette partie de liaison 16A est insérée dans cette partie formant rail 14A. Plus particulièrement, la surface arrière 18 est maintenue contre ladite surface de fond 15, et les surfaces latérales 20 contre les premières surfaces latérales 17.Each keying element 16 has a connecting portion 16A, comprising a rear surface 18 and two side surfaces 20 converging towards each other from the rear surface 18 to a front surface 22. This connecting portion 16A has a shape and dimensions complementary to those of the rail portion 14A of each groove 14, so that this connecting portion 16A can be held radially between the bottom surface and the first side surfaces of the rail portion 14A when this connecting portion 16A is inserted in this rail portion 14A. More particularly, the rear surface 18 is held against said bottom surface 15, and the side surfaces 20 against the first side surfaces 17.

Par ailleurs, chaque élément détrompeur 16 comporte une partie de fixation 16B, présentant une dimension latérale légèrement supérieure à la distance entre les secondes surfaces latérales 19 de la partie de coincement 14B de chaque rainure 14. Ainsi, lorsque cette partie de fixation 16B est insérée dans la partie de coincement 14B de l'une des rainures 14, elle y est maintenue par coincement entre ces secondes parois latérales 19.Furthermore, each polarizing element 16 comprises a fixing portion 16B, having a lateral dimension slightly greater than the distance between the second lateral surfaces 19 of the wedging portion 14B of each groove 14. Thus, when this fixing portion 16B is inserted in the wedging part 14B of one of the grooves 14, it is held there by wedging between these second side walls 19.

Avantageusement, la partie de fixation 16B comporte deux branches latérales 24, définissant ladite dimension latérale de cette partie de fixation 16B, ces branches latérales 24 étant écartées l'une de l'autre, et déformables élastiquement l'une vers l'autre. Ainsi, lorsque la partie de fixation 16B est insérée dans une partie de coincement 14B, les branches 24 sont comprimées l'une vers l'autre par les secondes parois latérales 19, si bien que le coincement est réalisé par un effort élastique exercé par ces branches latérales 24 sur les parois latérales 19.Advantageously, the fixing portion 16B comprises two lateral branches 24, defining said lateral dimension of this fixing portion 16B, these lateral branches 24 being spaced from one another, and elastically deformable towards one another. Thus, when the fixing portion 16B is inserted in a wedging portion 14B, the legs 24 are compressed towards one another by the second side walls 19, so that the wedging is achieved by an elastic force exerted by these side branches 24 on the side walls 19.

Il est à noter que les éléments détrompeurs 16 étant simplement fixés par coincement élastique, il est aisé de les insérer ou des les retirer des rainures 14, et cela sans nécessiter d'outil particulier. Ainsi, une prise électrique selon l'invention peut être mise en oeuvre ou démontée très rapidement grâce à cette facilité de montage, le codage étant réalisable et modifiable à volonté par l'opérateur.It should be noted that the keying elements 16 are simply fixed by elastic wedging, it is easy to insert or remove the grooves 14, and without requiring any particular tool. Thus, an electrical socket according to the invention can be implemented or disassembled very quickly thanks to this ease of assembly, the coding being achievable and modifiable at will by the operator.

Les branches latérales 24 sont par exemple jointes à chacune de leurs extrémités dans une direction longitudinale de l'élément détrompeur 16. En particulier, elles sont jointes à l'extrémité de l'élément détrompeur 16 par une partie profilée 26, présentant des parois convergentes vers cette extrémité pour faciliter l'insertion de l'élément détrompeur 16 dans une rainure 14.The lateral branches 24 are for example joined at each of their ends in a longitudinal direction of the polarizing element 16. In particular, they are joined to the end of the polarizing element 16 by a profiled part 26, presenting converging walls towards this end to facilitate the insertion of the polarizing element 16 in a groove 14.

La partie de liaison 16A de chaque élément détrompeur 16 présente de préférence une même longueur, dans la direction de l'axe longitudinal X, que la partie formant rail 14A de chaque rainure 14. Ainsi, cette partie de liaison 16A est entièrement contenue dans la partie formant rail 14A lorsque la partie de fixation 16B du même élément détrompeur 16 coopère avec la partie de coincement 14B de la même rainure 14.The connecting portion 16A of each polarizing element 16 preferably has the same length, in the direction of the longitudinal axis X, as the rail portion 14A of each groove 14. Thus, this connecting portion 16A is entirely contained in the rail portion 14A when the fixing portion 16B of the same biasing element 16 cooperates with the wedging portion 14B of the same groove 14.

On notera que les épaulements 21 définis entre les premières 17 et secondes 19 surfaces latérales forment des butées limitant le déplacement de la partie de liaison 16A dans la rainure 14.It will be noted that the shoulders 21 defined between the first 17 and second 19 lateral surfaces form stops limiting the displacement of the connecting portion 16A in the groove 14.

De préférence, chaque élément détrompeur 16 comporte en outre une partie 16C en saillie, par exemple en saillie depuis sa surface avant 22. Ainsi, cette partie en saillie 16C fait saillie radialement par rapport à la paroi de réception 12 lorsque l'élément détrompeur 16 est inséré dans l'une des rainures 14. Cette partie en saillie 16C est destinée à former une clavette coopérant avec une forme complémentaire ménagée sur l'organe complémentaire.Preferably, each polarizing element 16 further comprises a projecting portion 16C, for example protruding from its front surface 22. Thus, this projecting portion 16C protrudes radially relative to the receiving wall 12 when the polarizing element 16 is inserted into one of the grooves 14. This projecting portion 16C is intended to form a key cooperating with a complementary shape formed on the complementary member.

Plus particulièrement, l'organe complémentaire comprend une paroi de contact cylindrique, de forme complémentaire de celle de la paroi de réception 12, de manière à permettre l'enfichage de cet organe complémentaire avec le connecteur électrique 10. C'est cette paroi de contact qui comprend des formes complémentaires destinées à coopérer avec au moins l'une des rainures et/ou au moins l'un des éléments détrompeurs 16.More particularly, the complementary member comprises a cylindrical contact wall, of a shape complementary to that of the receiving wall 12, so as to allow the insertion of this complementary member with the electrical connector 10. It is this contact wall which comprises complementary shapes intended to cooperate with at least one of the grooves and / or at least one of the polarizing elements 16.

Par exemple, ces formes complémentaires comprennent au moins une rainure de réception de la partie en saillie 16C d'un élément détrompeur 16. Cette rainure doit alors se trouver en regard de l'élément détrompeur 16 dans la direction d'enfichage pour permettre cet enfichage.For example, these complementary shapes comprise at least one groove for receiving the protruding portion 16C of a polarizing element 16. This groove must then be opposite the polarizing element 16 in the direction of insertion to allow this insertion. .

En variante, ou de manière complémentaire, l'organe complémentaire peut également comprendre des parties de détrompage en saillie, destinés à coopérer avec des rainures 14 du connecteur.As a variant, or in a complementary manner, the complementary member may also comprise protruding keying parts intended to cooperate with grooves 14 of the connector.

Ainsi, dans un mode de réalisation préférentiel, chacun parmi le connecteur électrique 10 et l'organe complémentaire est muni, respectivement sur sa paroi de réception 12 et sa paroi de contact, de rainures longitudinales 14 propres à recevoir des éléments détrompeurs 16.Thus, in a preferred embodiment, each of the electrical connector 10 and the complementary member is provided, respectively on its receiving wall 12 and its contact wall, with longitudinal grooves 14 adapted to receive polarizing elements 16.

L'opérateur réalisant un circuit électrique peut alors insérer des éléments détrompeurs 16 dans certaines rainures 14 du connecteur électrique 10 et dans certaines rainures de l'organe complémentaire, de sorte que les éléments détrompeurs 16 du connecteur électrique 10 et se trouvent en regard de rainures libres de l'organe complémentaire, et vice versa. En d'autres termes, l'opérateur réalise lui-même le codage de la prise électrique.The operator realizing an electrical circuit can then insert polarizing elements 16 in certain grooves 14 of the electrical connector 10 and in certain grooves of the complementary member, so that the polarizing elements 16 of the electrical connector 10 and are opposite the free grooves of the complementary member, and vice versa. In other words, the operator himself performs the coding of the electrical outlet.

Pour des raisons de simplification, on n'a représenté que trois rainures 14 sur la figure 1. On comprendra aisément qu'il est possible de ménager un plus grand nombre de rainures sur la paroi de réception 12.For reasons of simplification, only three grooves 14 have been shown on the figure 1 . It will be readily understood that it is possible to provide a greater number of grooves on the receiving wall 12.

Dans cet exemple à trois rainures 14, l'opérateur peut insérer un élément détrompeur 16 dans l'une quelconque des rainures, dans deux rainures quelconques, dans les trois rainures, ou dans aucune des rainures. En d'autres termes, il est possible de former huit combinaisons de codage pour ce connecteur électrique 10.In this example with three grooves 14, the operator can insert a polarizing element 16 in any one of the grooves, in any two grooves, in the three grooves, or in any of the grooves. In other words, it is possible to form eight coding combinations for this electrical connector 10.

De manière optionnelle, deux connecteurs électriques différents peuvent être munis d'éléments détrompeurs 16 de couleurs différentes, permettant de simplifier l'identification des connecteurs grâce aux couleurs des éléments détrompeurs 16. En d'autres termes, on forme ainsi une aide visuelle pour les opérations de câblage.Optionally, two different electrical connectors may be provided with polarizing elements 16 of different colors, making it possible to simplify the identification of the connectors by virtue of the colors of the polarizing elements 16. In other words, a visual aid is thus formed for them. wiring operations.

On notera que l'invention n'est pas limitée au mode de réalisation précédemment décrit, mais pourrait présenter diverses variantes sans sortir du cadre des revendications.Note that the invention is not limited to the embodiment described above, but could have various variants without departing from the scope of the claims.
