CONNECTEUR ELECTRIQUE FEMELLE, MÂLE ET CONNEXION ELECTRIQUE UTILISANT CE CONNECTEUR ELECTRIQUE FEMELLE ET/OU MÂLE FEMALE ELECTRICAL CONNECTOR, MALE AND ELECTRICAL CONNECTION USING THIS FEMALE AND / OR MALE ELECTRICAL CONNECTOR
L'invention se rapporte à une connexion femelle/ mâle utilisée par exemple pour permettre de transmettre du courant électrique vers un système chauffant d'un vitrage ou vers un système d'antenne d'un vitrage et en particulier un vitrage de véhicule.The invention relates to a female / male connection used for example for transmitting electrical power to a heating system of a glazing unit or to an antenna system of a glazing unit and in particular a vehicle glazing unit.
Le connecteur électrique femelle présente habituellement au moins une partie distale de câblage destinée à être reliée à un câble électrique et au moins une partie proximale de branchement comportant une ouverture présentant une forme générale de couronne orientée selon un axe central, ladite couronne étant destinée à coopérer avec un appendice d'un connecteur électrique mâle orienté selon un axe central afin de permettre une liaison électrique entre les deux connecteurs par l'intermédiaire d'une pluralité de pattes reliées à ladite couronne, chaque patte présentant une base qui est attachée à la couronne et une tête qui est écartée de la couronne et qui entre en contact avec ledit appendice pour opérer la liaison électrique.The female electrical connector usually has at least one distal portion of wiring intended to be connected to an electrical cable and at least one proximal branch portion having an opening having a generally crown shape oriented along a central axis, said ring being intended to cooperate with an appendage of a male electrical connector oriented along a central axis to allow electrical connection between the two connectors via a plurality of tabs connected to said ring, each tab having a base which is attached to the ring and a head which is spaced from the ring and which comes into contact with said appendage to effect the electrical connection.
Le connecteur électrique mâle comporte habituellement au moins un appendice orienté selon un axe central, ledit connecteur électrique mâle étant destinée à coopérer avec le connecteur électrique femelle précédemment présenté.The male electrical connector usually comprises at least one appendage oriented along a central axis, said male electrical connector being intended to cooperate with the female electrical connector previously presented.
Actuellement, les vitrages chauffant de véhicules et en particulier les lunettes arrières sont munis pour leur alimentation en courant électrique d'une connexion pré étamée et la soudure électrique du câble sur le vitrage est réalisée en atelier avancé, c'est-à-dire sur la ligne d'assemblage et de montage des véhicules, par le constructeur automobile.Currently, the heated windows of vehicles and in particular the rear glasses are provided for their power supply with a pre-tinned connection and the electrical welding of the cable on the glazing is performed in advanced workshop, that is to say on the vehicle assembly and assembly line, by the car manufacturer.
Ceci n'est pas pratique et il existe une attente forte des constructeurs automobiles de pouvoir installer directement dans la baie de la carrosserie un vitrage prêt à être branché au reste du système électrique du véhicule. Le verrier fourni alors au constructeur automobile des vitrages comportant un élément mâle fixé préalablement au vitrage et après montage du vitrage dans la baie de la carrosserie, il n'y a plus qu'à cliper un élément femelle de connexion sur l'élément mâle pour raccorder les éléments électriques du vitrage au faisceau électrique du véhicule. La liaison électrique à la surface du vitrage est ainsi réalisée en atelier avancé, par clipage.This is not practical and there is a strong expectation of car manufacturers to be able to install directly in the bodyshell a window ready to be connected to the rest of the vehicle electrical system. The glassblower then supplied to the car manufacturer of glazings comprising a male element fixed before the glazing and after assembly of the glazing in the bay of the bodywork, it is only necessary to clip a female connection element on the male element for connect the electrical elements of the glazing to the vehicle's wiring harness. The electrical connection to the surface of the glazing is thus carried out in an advanced workshop, by clipping.
Cette solution simplifie le pré-montage du faisceau par une liaison électrique clipée et non soudée.This solution simplifies pre-assembly of the beam by an electrical connection clip and not welded.
Il n'est ainsi plus besoin de multiplier les compétences de l'art de la soudure dans les différents ateliers avancés, la liaison électrique s'en trouve fiabilisée, les risques de clivage du vitrage sont éliminés et il est possible de réaliser une standardisation de la liaison (qui devient identique pour toutes les fonctions) : antenne, chauffage, commande d'ouverture, feu de stop, ...It is thus no longer necessary to multiply the skills of the art of welding in the various advanced workshops, the electrical connection is made reliable, the risks of cleavage of the glazing are eliminated and it is possible to achieve a standardization of the link (which becomes the same for all functions): antenna, heating, opening control, stop light, ...
L'art antérieur connaît du brevet américain N0 LJS 6,039,616 un connecteur mâle et du brevet américain N0 LJS 6,520,812 un connecteur femelle qui pourraient être utilisés pour l'application exposée ci-avant.The prior art known from US Patent No. 0 LJS 6,039,616 a male connector and U.S. Patent No. 0 6,520,812 LJS a female connector that could be used for the purposes set out above.
Toutefois la liaison électrique ainsi réalisée par coopération de ces deux connecteurs ne donne pas satisfaction car le déclipage s'opère trop facilement. Pour mesurer l'effort d'extraction nécessaire pour décliper une connexion, il est possible d'utiliser une machine de traction et d'opérer une traction sur la liaison électrique.However, the electrical connection thus made by cooperation of these two connectors is not satisfactory because the decliping is too easy. To measure the extraction force required to open a connection, it is possible to use a traction machine and to pull the electrical connection.
Les tests réalisés en laboratoire ont montrés que la valeur moyenne de l'effort d'insertion des liaisons dite « de puissance » par exemple pour le chauffage est de 56,5 N, mais que la valeur moyenne de l'effort d'extraction de ces liaisons de puissance est de 64,2 N, ce qui est très proche.Tests carried out in the laboratory have shown that the average value of the insertion effort of the so-called "power" links for example for heating is 56.5 N, but that the average value of the extraction effort of these power links is 64.2 N, which is very close.
Il est préférable que la valeur de l'effort d'extraction soit raisonnable pour permettre au besoin de changer le vitrage, sans changer le connecteur électrique femelle, mais une si petite différence entre les deux valeurs d'effort opposées n'est pas acceptable car elle implique que le connecteur femelle risque de se décliper trop facilement du connecteur mâle. Il est certes possible de noyer la liaison électrique dans une matière plastique, mais alors, il n'est plus possible de changer le vitrage sans changer le connecteur femelle : lorsque le vitrage est changé, il faut aussi changer tout la liaison électrique, ce qui augmente bien sûr le coût du vitrage de remplacement.It is preferable that the value of the pulling force is reasonable to allow the need to change the glazing without changing the female electrical connector, but such a small difference between the two opposing force values is not acceptable because it implies that the female connector may easily fall off the male connector. It is certainly possible to drown the electrical connection in a plastic material, but then, it is no longer possible to change the glazing without changing the female connector: when the glazing is changed, it is also necessary to change the entire electrical connection, which of course increases the cost of replacement glazing.
La présente invention entend remédier aux inconvénients de l'art antérieur en proposant un connecteur électrique femelle qui présente un effort d'extraction moyen qui est supérieur à l'effort d'insertion moyen. La présente invention repose sur une analyse séparée des différents moyens nécessaires à la mise en œuvre d'un connecteur électrique femelle du type de celui présenté ci-avant et coopérant avec un connecteur électrique mâle.The present invention intends to overcome the disadvantages of the prior art by proposing a female electrical connector which has a mean extraction force which is greater than the average insertion force. The present invention is based on a separate analysis of the various means necessary for the implementation of a female electrical connector of the type shown above and cooperating with a male electrical connector.
Il se trouve que les moyens qui permettent de maintenir le connecteur électrique femelle sur le connecteur électrique mâle peuvent être séparés des moyens nécessaires au passage du courant entre les connecteurs électriques.It is found that the means for maintaining the female electrical connector on the male electrical connector can be separated from the means necessary for the passage of current between the electrical connectors.
Or, la flexibilité des moyens nécessaires au passage du courant doit être grande afin d'assurer que ces moyens soient en permanence bien plaqués contre le connecteur électrique mâle alors que la flexibilité des moyens qui permettent de maintenir le connecteur électrique femelle sur le connecteur électrique mâle doit être en proportion plus faible pour ne pas que l'extraction soit trop facile.However, the flexibility of the means required for the passage of the current must be large to ensure that these means are permanently well pressed against the male electrical connector while the flexibility of the means for maintaining the female electrical connector on the male electrical connector must be in a lower proportion so that the extraction is not too easy.
L'invention a ainsi pour objet, dans son acception la plus large, un connecteur électrique femelle selon la revendication 1. Ce connecteur électrique femelle est remarquable en ce qu'il comporte au moins une (et de préférence au moins deux) patte(s) de retenu en forme de griffe et au moins une (et de préférence au moins deux) patte(s) de connexion électrique en forme de palettes, la (ou les) griffe(s) présentant une base d'une largeur supérieure ou égale à la largeur de sa (ou leur) tête et la (ou les) palette(s) présentant une base d'une largeur inférieure à la largeur de la (ou leur) tête. - A -The object of the invention is therefore, in its broadest sense, a female electrical connector according to claim 1. This female electrical connector is remarkable in that it comprises at least one (and preferably at least two) tab (s). ) claw-shaped retainer and at least one (and preferably at least two) pallet-shaped electrical connection tab (s), the claw (s) having a base of greater or equal width the width of its (or their) head and the (or) pallet (s) having a base of a width less than the width of the (or their) head. - AT -
Ainsi, la (ou les) palette(s) de connexion électrique est (ou sont) plus flexible(s) que la (ou les) griffe(s) de retenu et il est alors possible d'obtenir un effort d'extraction moyen qui est supérieur à l'effort d'insertion moyen tout en conservant une grande fiabilité pour la liaison électrique. La largeur de la tête d'au moins une palette (et de préférence de toutes les palettes) est, de préférence, au moins 1 ,5 fois, et de préférence encore au moins deux fois, voire au moins 2,5 fois, plus grande que la largeur de la base de cette palette (ou de ces palettes).Thus, the (or) pallet (s) of electrical connection is (or are) more flexible (s) than the claw (s) retained and it is possible to obtain an average extraction effort which is greater than the average insertion force while maintaining high reliability for the electrical connection. The width of the head of at least one pallet (and preferably of all pallets) is preferably at least 1.5 times, and more preferably at least twice, or even at least 2.5 times, more large than the width of the base of this pallet (or of these pallets).
La hauteur d'une (ou des) palette(s) considérée à partir du dessous de la couronne est, de préférence, au moins le double de la hauteur d'une (ou des) griffe(s) considérée à partir de cette même référence.The height of one (or more) pallet (s) considered from below the crown is preferably at least twice the height of one (or more) claw (s) considered from this same reference.
Les pattes selon l'invention présentent par ailleurs, de préférence, une épaisseur identique entre elles et constante de leur base à leur tête.The tabs according to the invention also have, preferably, an identical thickness between them and constant from their base to their heads.
La hauteur d'une (ou des) griffe(s) considérée à partir du dessous de la couronne est, de préférence, inférieure à la hauteur de l'appendice du connecteur électrique mâle, ladite hauteur d'une (ou des) griffe(s) étant de préférence encore sensiblement égale à la moitié de ladite hauteur.The height of one (or more) claw (s) considered from below the crown is preferably lower than the height of the appendage of the male electrical connector, said height of one (or more) claw ( s) being preferably still substantially equal to half of said height.
Lorsque le connecteur électrique femelle ne coopère pas encore avec ledit connecteur électrique mâle, la distance intérieure entre les têtes de deux palettes diamétralement opposées par rapport à l'axe A est, de préférence, au moins 90 % de la distance entre deux parois extérieures de l'appendice.When the female electrical connector does not yet cooperate with said male electrical connector, the internal distance between the heads of two diametrically opposed pallets with respect to the axis A is preferably at least 90% of the distance between two outer walls of Appendix.
Lorsque le connecteur électrique femelle ne coopère pas encore avec ledit connecteur électrique mâle, la distance intérieure entre les têtes de deux griffes diamétralement opposées par rapport à l'axe A est, de préférence, au moins 90 % de la distance entre deux parois extérieures de l'appendice.When the female electrical connector does not yet cooperate with said male electrical connector, the internal distance between the heads of two claws diametrically opposite with respect to the axis A is preferably at least 90% of the distance between two outer walls of Appendix.
Cette distance intérieure entre les têtes de deux palettes diamétralement opposées par rapport à l'axe A est en outre, dans une variante, inférieure à la distance intérieure entre les têtes de deux griffes diamétralement opposées par rapport à l'axe A. Lorsque le connecteur électrique femelle coopère avec ledit connecteur électrique maie, la tête d'au moins une palette (et de préférence de toutes les palettes) est, de préférence, en contact surfacique avec ledit appendice du connecteur électrique maie alors que la tête d'au moins une griffe (et de préférence de toutes les griffes) est en contact linéique, voire ponctuel, avec ledit appendice.This inner distance between the heads of two diametrically opposite pallets with respect to the axis A is, in a variant, smaller than the internal distance between the heads of two claws diametrically opposite with respect to the axis A. When the female electrical connector cooperates with said electrical connector maie, the head of at least one pallet (and preferably all pallets) is preferably in surface contact with said appendage of the electrical connector maie while the head of at least one claw (and preferably all claws) is in line contact, even punctual, with said appendix.
Ce contact surfacique entre chaque tête des palettes et l'appendice est de préférence compris entre 1 mm2 et 5 mm2, et de préférence d'au moins 1 ,5 mm2, ou d'au moins 2 mm2, voire d'au moins 3mm2. Dans une variante, les griffes et les palettes sont alternées sur le pourtour de la couronne de telle sorte que l'angle entre une griffe et une palette adjacente sur le pourtour de la couronne soit toujours identique et notamment de l'ordre de 45° ou de l'ordre de 30° , ou de l'ordre de 22,5° .This surface contact between each head of the pallets and the appendage is preferably between 1 mm 2 and 5 mm 2 , and preferably at least 1.5 mm 2 , or at least 2 mm 2 , or even at least 3mm 2 .

Un appendice d'un connecteur électrique mâle capable de coopérer avec le connecteur femelle selon l'invention peut être à section extérieure complètement circulaire et présenter ainsi une symétrie axiale ou ne pas présenter une telle symétrie axiale et présenter ainsi une orientation particulière : à ce titre, il peut être à section extérieure circulaire tronqué au moins une fois, voire à section extérieure circulaire tronqué plusieurs fois ou encore être à section extérieure non circulaire à plusieurs pans ou faces.An appendage of a male electrical connector capable of cooperating with the female connector according to the invention may be of completely circular outer section and thus have axial symmetry or may not have such axial symmetry and thus have a particular orientation: as such it may be circular outer section truncated at least once, or circular outer section truncated several times or be outer non-circular section with several sides or faces.

An embodiment of the female electrical connector 1 according to the invention is illustrated in FIG.
Ce connecteur électrique femelle 2 présente une partie distale de câblage C destinée à être reliée à un câble électrique et une partie proximale de branchement B.This female electrical connector 2 has a distal portion of wiring C intended to be connected to an electrical cable and a proximal branch portion B.
Le connecteur électrique femelle 2 selon l'invention peut présenter deux (ou plus encore) parties proximales de branchement B et deux (ou plus) parties distales de câblage C destinées chacune à être reliée à un câble électrique ou une partie distale de câblage C destinée à être reliée à plusieurs câbles électriques. Chaque partie proximale de branchement B est alors, de préférence, à patte(s) de retenu et à patte(s) de connexion électrique conformément à la présente invention.The female electrical connector 2 according to the invention may have two (or more) proximal connection portions B and two (or more) distal wiring portions C each intended to be connected to an electrical cable or a distal portion C intended to to be connected to several electric cables. Each proximal branch portion B is then preferably with a retaining tab (s) and electrical connection tab (s) in accordance with the present invention.
La partie distale de câblage C comporte une gorge 8 pour l'accueil de l'extrémité dénudée du câble électrique. Cette gorge présente en coupe transversale une forme sensiblement en LJ dont les ailes peuvent être repliées vers la base afin de servir l'extrémité du câble.The distal portion of wiring C has a groove 8 for receiving the stripped end of the electrical cable. This groove has in cross section a substantially LJ shape whose wings can be folded towards the base to serve the end of the cable.
La partie distale de câblage C présente une symétrie axiale selon un axe D qui passe par le fond de la gorge 8. La partie proximale de branchement B comporte une ouverture 26 présentant une forme générale de couronne 28 qui est ici de forme intérieure circulaire et de forme extérieure également circulaire concentrique avec la précédente, ladite couronne étant orientée selon un axe central A.The distal portion of wiring C has an axial symmetry along an axis D which passes through the bottom of the groove 8. The proximal branch portion B has an opening 26 having the general shape of a ring 28 which is here of circular internal shape and of outer shape also circular concentric with the previous one, said ring being oriented along a central axis A.
La proximale de branchement B présente aussi une symétrie axiale selon un axe qui est ici confondu avec l'axe D de la partie distale de câblage C. Les axes A et D sont ainsi perpendiculaires.The proximal connection B also has an axial symmetry along an axis which is here coincident with the axis D of the distal portion of wiring C. The axes A and D are thus perpendicular.
Il est tout à fait possible d'imaginer que l'ouverture 26 ne soit pas circulaire mais présente plusieurs faces, de préférence en nombre pair afin de conserver la symétrie dans la tenue mécanique vis-à-vis de l'axe A et de l'axe D. La couronne 28 de la partie proximale de branchement B est destinée à coopérer avec un appendice 40 d'un connecteur électrique mâle 4 illustré à titre d'exemple en figure 2.It is quite possible to imagine that the opening 26 is not circular but has several faces, preferably even in order to maintain the symmetry in mechanical strength vis-à-vis the axis A and the D. axis The ring 28 of the proximal branch portion B is intended to cooperate with an appendage 40 of a male electrical connector 4 illustrated by way of example in FIG.
Cet appendice 40 est orienté selon un axe central T. L'appendice 40 est par exemple un cylindre (ou un tube) présentant un diamètre extérieur d3 inférieur ou diamètre intérieur d28 de la couronne 28. f28 désigne le diamètre extérieur de la couronne 28.This appendix 40 is oriented along a central axis T. The appendix 40 is for example a cylinder (or a tube) having an outside diameter d3 or d28 inside the diameter of the ring 28. f28 designates the outside diameter of the ring 28.
La couronne ne rentrant ainsi pas directement en contact avec ledit appendice, elle peut avoir une forme intérieure similaire à celle en coupe transversale de l'appendice et qui suit ainsi le contour extérieur de l'appendice ou une forme quelconque. Elle peut aussi avoir une forme extérieure similaire à celle en coupe transversale de l'appendice et qui suit ainsi le contour extérieur de l'appendice ou une forme quelconque.The crown thus not coming directly into contact with said appendix, it may have an inner shape similar to that in cross section of the appendix and which thus follows the outer contour of the appendix or any shape. It may also have an outer shape similar to that in cross section of the appendix and which thus follows the outer contour of the appendix or any shape.
Le connecteur mâle 4 comporte en plus de l'appendice 40 une base 41 d'un diamètre extérieur supérieur au diamètre extérieur de l'appendice 40.The male connector 4 comprises in addition to the appendix 40 a base 41 with an outside diameter greater than the outside diameter of the appendix 40.
C'est par l'intermédiaire de cette base que le connecteur mâle 4 est relié électriquement par exemple à une surface conductrice d'un élément vitré. h2 désigne la hauteur totale du connecteur mâle.It is through this base that the male connector 4 is electrically connected for example to a conductive surface of a glazed element. h2 is the total height of the male connector.
L'appendice 40 peut aussi être en forme générale de cône cylindrique, avec une partie proche de la base 41 moins large que la partie éloignée de la base 41. L'angle α de la paroi de l'appendice 40 par rapport à la base 41 peut ainsi être légèrement inférieur à 90 ° , comme par exemple 87 ° ou 85 ° .The appendix 40 may also be in the general shape of a cylindrical cone, with a part near the base 41 which is less wide than the part remote from the base 41. The angle α of the wall of the appendage 40 with respect to the base 41 can thus be slightly less than 90 °, such as for example 87 ° or 85 °.
L'appendice 40 peut aussi présenter au moins une face plate et présenter ainsi en coupe transversale, parallèle à la base 41 une forme circulaire tronquée.Appendix 40 may also have at least one flat face and thus have a truncated circular shape parallel to the base 41 in cross section.
L'appendice 40 peut aussi présenter plusieurs faces plates et présenter ainsi en coupe parallèle à la base 41 une forme de triangle, carré, rectangle, losange, hexagone, octogone, pentagone, ...Appendix 40 may also have several flat faces and thus have a section parallel to the base 41 a shape of triangle, square, rectangle, rhombus, hexagon, octagon, pentagon, ...
La coopération entre le connecteur femelle 2 et le connecteur mâle 4 pour permettre une liaison électrique entre les deux connecteurs s'opère en disposant la couronne 28 autour de l'appendice 40 de telle sorte que leurs axes respectifs A et T se confondent dans l'espace.The cooperation between the female connector 2 and the male connector 4 to allow an electrical connection between the two connectors is effected by disposing the ring 28 around the appendix 40 so that their respective axes A and T merge into the space.
Le connecteur mâle 4 étant par exemple soudé sur une surface conductrice d'un élément verrier tel qu'un vitrage de véhicule, la translation de la couronne 28 selon l'axe T de telle sorte que l'axe A de la couronne 28 soit confondu avec l'axe T permet ainsi d'enfiler le connecteur femelle 2 sur le connecteur mâle 4.The male connector 4 being for example welded to a conductive surface of a glass element such as a vehicle glazing, the translation of the ring 28 along the axis T such that the axis A of the ring 28 is merged with the T-axis thus makes it possible to thread the female connector 2 on the male connector 4.
Toutefois, cette coopération est telle que la couronne 28 ne rentre pas directement en contact avec l'appendice 40 : ce sont des pattes, liées mécaniquement à la couronne, qui permettent la retenue mécanique contre l'appendice et la liaison électrique avec cet appendice.However, this cooperation is such that the ring 28 does not come into direct contact with Appendix 40: they are tabs, mechanically linked to the crown, which allow the mechanical retention against the appendage and the electrical connection with this appendix.
Chaque patte présente une base qui est attachée physiquement à la couronne et une tête qui n'est pas attachée physiquement à la couronne mais qui est écartée de la couronne et qui entre en contact avec ledit appendice lors de la coopération.Each leg has a base which is physically attached to the crown and a head which is not physically attached to the crown but which is spaced apart from the crown and comes into contact with the said appendage during the cooperation.
Selon l'invention, le connecteur électrique femelle 2 comporte au moins deux pattes, et de préférence un nombre pair de pattes, et les pattes se distinguent en deux catégories :According to the invention, the female electrical connector 2 comprises at least two tabs, and preferably an even number of tabs, and the tabs are distinguished into two categories:
- au moins une (ou une pluralité de) patte(s) de retenu en forme de griffe 20, qui a (ou ont chacune) pour fonction essentielle de réaliser la coopération mécanique entre le connecteur femelle et le connecteur mâle etat least one (or a plurality) claw-shaped retaining tab (s) 20, which has (or has each) an essential function of effecting the mechanical cooperation between the female connector and the male connector and
- au moins une (ou une pluralité de) patte(s) de connexion en forme de palette 30, qui a (ou ont chacune) pour fonction essentielle de réaliser la liaison électrique entre le connecteur femelle et le connecteur mâle.at least one (or a plurality of) pad-shaped connection tabs 30, which has (or has each) an essential function of making the electrical connection between the female connector and the male connector.
Cela ne signifie pas qu'aucune liaison électrique n'est opérée par l'intermédiaire de la (ou des) griffe(s) et qu'aucune coopération mécanique n'est opérée par l'intermédiaire de la (ou des) palette(s), mais chaque catégorie de patte présente une configuration qui lui est propre et qui est étudiée pour répondre à l'objectif de la fonction essentielle qui lui est attachée :This does not mean that no electrical connection is operated via the claw (s) and that no mechanical cooperation is operated via the (or) pallet (s) ), but each leg category has its own configuration and that is studied to fulfill the purpose of the essential function attached to it:
- chaque griffe 20 présentant une base 21 d'une largeur 121 supérieure ou égale à la largeur 122 de sa tête 22, et - chaque palette 30 présentant une base 31 d'une largeur 131 inférieur à la largeur 132 de sa tête 32.each claw 20 having a base 21 with a width 121 greater than or equal to the width 122 of its head 22, and - each blade 30 having a base 31 of a width 131 smaller than the width 132 of its head 32.
Toutefois, ce ne sont pas les seules caractéristiques attachées à chaque catégorie de patte.However, these are not the only features attached to each leg category.
Ainsi, de préférence, pour chaque griffe 20 : - la tête 22 est en contact linéique N avec l'appendice 40 du connecteur électrique maie 4, comme on peut le constater sur la figure 3 ;Thus, preferably, for each claw 20: - the head 22 is in linear contact N with the appendix 40 of the electrical connector maie 4, as can be seen in Figure 3;
- la distance intérieure d22 (ici le diamètre intérieur), visible sur la figure 4, entre les têtes 22 de deux griffes diamétralement opposées par rapport à l'axe A est au moins 90 % de la largeur extérieure d40, c'est à dire la distance entre les parois extérieures (ici le diamètre extérieur) de l'appendice 40 lorsque le connecteur électrique femelle 2 ne coopère pas avec ledit connecteur électrique maie 4 ;the internal distance d22 (here the inside diameter), visible in FIG. 4, between the heads 22 of two claws diametrically opposite with respect to the axis A is at least 90% of the external width d40, that is to say the distance between the outer walls (here the outer diameter) of the appendix 40 when the female electrical connector 2 does not cooperate with said electrical connector 4;
- la hauteur h20 de chaque griffe considérée à partir du dessous de la couronne 11 est inférieure à la hauteur h40 de l'appendice 40 du connecteur électrique mâle.the height h20 of each claw considered from below the ring 11 is less than the height h40 of the appendix 40 of the male electrical connector.
Par ailleurs, de préférence, pour chaque palette 30 :Moreover, preferably, for each pallet 30:
- la tête 32 est en contact surfacique S, voire ponctuel, avec ledit appendice 40 du connecteur électrique maie 4, comme on peut le constater sur la figure 6 ; - la distance intérieure d32 (ici le diamètre intérieur), visible sur la figurethe head 32 is in surface contact S, even punctual, with said appendix 40 of the electrical connector 4, as can be seen in FIG. 6; - the internal distance d32 (here the inside diameter), visible in the figure
7, entre les têtes 32 de deux palettes diamétralement opposées par rapport à l'axe A est au moins 90 % de la largeur extérieure d40 entre les parois extérieures (ici le diamètre extérieur) de l'appendice 40 lorsque le connecteur électrique femelle 2 ne coopère pas avec ledit connecteur électrique maie 4 ; - la hauteur h30 de chaque palette considérée à partir du dessous de la couronne 11 est sensiblement égale à la hauteur h40 de l'appendice 40 du connecteur électrique mâle ; ou en tout cas, il n'est pas nécessaire que la hauteur h30 soit supérieure à la hauteur h40 ;7, between the heads 32 of two diametrically opposite pallets with respect to the axis A is at least 90% of the external width d40 between the outer walls (here the outside diameter) of the appendix 40 when the female electrical connector 2 is not connected. does not cooperate with said electrical connector 4; the height h30 of each pallet considered from below the ring 11 is substantially equal to the height h40 of the appendix 40 of the male electrical connector; or in any case, the height h30 need not be greater than the height h40;
- la hauteur h30 de chaque palette considérée à partir du dessous de la couronne 11 est au moins le double de la hauteur h20 des griffes 20 considérée à partir de cette même référence ;the height h30 of each pallet considered from below the crown 11 is at least twice the height h20 of the claws 20 considered from this same reference;
- la largeur 132 de la tête 32 de chaque palette est plus grande que la largeur 131 de la base 31 de ces palettes, comme on peut le constater sur la figure 8.- The width 132 of the head 32 of each pallet is greater than the width 131 of the base 31 of these pallets, as can be seen in Figure 8.
Dans le cadre de l'invention par ailleurs, la largeur 131 de la base 31 de chaque palette 30 est, de préférence au moins 1 ,5 fois, et de préférence au moins deux fois, plus petite que la largeur 121 de la base 21 des griffes 20.In the context of the invention moreover, the width 131 of the base 31 of each pallet 30 is preferably at least 1.5 times, and preferably at least twice, smaller than the width 121 of the base 21. claws 20.
En outre, dans chaque catégorie de pattes, les pattes sont, de préférence, en nombre pair, afin de conserver les symétries axiales selon les axes A et D. Il est alors possible de réaliser d'une part une pince de griffes à l'aide de deux griffes diamétralement opposées par rapport à l'axe A et d'autre part une pince de palettes à l'aide de deux palettes diamétralement opposées par rapport à l'axe A.In addition, in each category of tabs, the tabs are preferably even in number so as to maintain the axial symmetries along the axes A and D. It is then possible to produce on the one hand a gripper of claws on the using two claws diametrically opposite to the axis A and on the other hand a pallet clamp with two vanes diametrically opposite to the axis A.
Lorsque le connecteur électrique femelle 2 est introduit sur le connecteur électrique maie 4, les têtes 32 des palettes 30 s'écartent dans une direction centripète par rapport à l'axe A et la distance intérieure d32 entre les têtes 32 de deux palettes diamétralement opposées par rapport à l'axe A devient sensiblement identique à la distance entre les parois extérieures (ici le diamètre extérieur) d40 de l'appendice 40.When the female electrical connector 2 is introduced on the electrical connector maie 4, the heads 32 of the vanes 30 deviate in a centripetal direction relative to the axis A and the inner distance d32 between the heads 32 of two vanes diametrically opposed by relative to the axis A becomes substantially identical to the distance between the outer walls (here the outer diameter) d40 of the appendix 40.
De même, lorsque le connecteur électrique femelle 2 est introduit sur le connecteur électrique maie 4, les têtes 22 des griffes 20 s'écartent dans une direction centripète par rapport à l'axe A et la distance intérieure d22 entre les têtes 22 de deux griffes diamétralement opposées par rapport à l'axe A devient sensiblement identique à la distance entre les parois extérieures (ici le diamètre extérieur) d40 de l'appendice 40. Le connecteur électrique femelle 2 illustré en figure 1 comporte quatre griffes 20 et deux palettes 30.Similarly, when the female electrical connector 2 is introduced on the electrical connector 4, the heads 22 of the claws 20 deviate in a centripetal direction relative to the axis A and the inner distance d22 between the heads 22 of two claws diametrically opposite to the axis A becomes substantially identical to the distance between the outer walls (here the outer diameter) d40 of the appendix 40. The female electrical connector 2 illustrated in FIG. 1 comprises four claws 20 and two vanes 30.
Les pattes d'une même catégorie sont disposées en vis-à-vis une à une diamétralement opposées par rapport audit axe A de la couronne : il n'y a donc pas dans cette configuration de griffe en face par rapport à l'axe A d'une palette, ou inversement.The legs of the same category are arranged vis-à-vis one to one diametrically opposite with respect to said axis A of the ring: there is therefore not in this face claw configuration with respect to the axis A of a palette, or vice versa.
Le tableau ci-dessous présente des valeurs possibles pour chacun des paramètres de largeur, diamètre ou hauteur des figures 2 à 8 (en mm) :The table below shows possible values for each of the width, diameter or height parameters in Figures 2 to 8 (in mm):
Ainsi, le contact surfacique S entre chaque tête 32 et l'appendice 40 est ici de l'ordre de 4 mm2. (2 x 1 ,9 = 3,8 mm2).Thus, the surface contact S between each head 32 and the appendage 40 is here of the order of 4 mm 2 . (2 x 1, 9 = 3.8 mm 2 ).
Le contact surfacique total entre toutes les têtes 32 et l'appendice 40 est ainsi ici de l'ordre de 8 mm2. (2 x 2 x 1 ,9 = 7,6 mm2).The total surface contact between all the heads 32 and the appendage 40 is thus of the order of 8 mm 2 . (2 x 2 x 1, 9 = 7.6 mm 2 ).
La hauteur h20 est ici sensiblement égale à la moitié de la hauteur h3 et même légèrement inférieure à la moitié de ladite hauteur h3.The height h20 is here substantially equal to half the height h3 and even slightly less than half said height h3.
La hauteur h30 est ici identique à la hauteur h3.The height h30 is here identical to the height h3.
La distance intérieure d22 est ici égale à environ 96,5 % de la distance extérieure d40 et la distance intérieure d32 est égale à environ 94,7 % de la distance extérieure d40.The internal distance d22 here is equal to about 96.5% of the outside distance d40 and the inner distance d32 is equal to about 94.7% of the outside distance d40.
La largeur 131 de la base 31 des palettes est ici environ 2,5 fois plus petite que la largeur 121 de la base 21 des griffes.The width 131 of the base 31 of the pallets is here about 2.5 times smaller than the width 121 of the base 21 of the claws.
Pour des raisons de facilité de fabrication, le rayon r20 de la liaison entre la base 21 et la couronne 11 est identique au rayon r30 de la liaison entre la base 31 et la couronne 28 ; de même, l'épaisseur e20 de la matière constitutive des griffes 20 est identique à l'épaisseur e30 de la matière constitutive des palettes 30 et est identique à l'épaisseur e28 de la couronne 28 : de l'ordre de 0,5 mm.For reasons of ease of manufacture, the radius r20 of the connection between the base 21 and the ring 11 is identical to the radius r30 of the connection between the base 31 and the ring 28; likewise, the thickness e20 of the material constituting the claws 20 is identical to the thickness e30 of the material constituting the pallets 30 and is identical to the thickness e28 of the ring 28: of the order of 0.5 mm.
Toutefois, indépendamment de la solution selon laquelle , il pourrait être envisagé d'une part que la base 21 d'au moins une griffe (et de préférence toutes les griffes) présente une surépaisseur de matière pour rendre la liaison de cette griffe (ou de ces griffes) avec la couronne plus rigide , avec par exemple une épaisseur e20 > 110 % de e28, voire e20 > 120 % de e28 et/ou d'autre part que la base 31 d'au moins une palette (et de préférence toutes les palettes) présente un rétrécissement d'épaisseur de matière pour rendre la liaison de cette palette (ou de ces palettes) avec la couronne plus flexible, avec par exemple une épaisseur e30 < 90 % de e28, voire e30 < 80 % de e28. Cette solution permet aussi d'obtenir un effort d'extraction moyen qui est supérieur à l'effort d'insertion moyen tout en conservant une grande fiabilité pour la liaison électrique.However, regardless of the solution according to which, it could be envisaged on the one hand that the base 21 of at least one claw (and preferably all the claws) has an extra thickness of material to make the connection of this claw (or these claws) with the stiffer ring, for example with a thickness e20> 110% of e28, or e20> 120% of e28 and / or secondly that the base 31 of at least one pallet (and preferably all the pallets) has a material thickness shrinkage to make the connection of this pallet (or pallets) with the more flexible crown, with for example a thickness e30 <90% of e28, or e30 <80% of e28. This solution also allows to obtain an average extraction force which is greater than the average insertion force while maintaining high reliability for the electrical connection.
Comme on peut le voir en figure 9, la distance intérieure entre les têtes 32 de deux palettes 30 diamétralement opposées par rapport à l'axe A est inférieure à la distance intérieure entre les têtes 22 de deux griffes 20 diamétralement opposées par rapport à l'axe A. Cela est possible du fait que les palettes 30 sont plus flexibles que les griffes 20.As can be seen in FIG. 9, the internal distance between the heads 32 of two vanes 30 diametrically opposite with respect to the axis A is less than the internal distance between the heads 22 of two claws 20 diametrically opposite with respect to the A. This is possible because the pallets 30 are more flexible than the claws 20.
La distance intérieure entre les têtes 32 de deux palettes 30 diamétralement opposées par rapport à l'axe A peut aussi être sensiblement identique à la distance intérieure entre les têtes 22 de deux griffes 20 diamétralement opposées par rapport à l'axe A, mais par contre, il n'est pas envisageable que la distance intérieure entre les têtes 32 de deux palettes 30 diamétralement opposées par rapport à l'axe A soit supérieure à la distance intérieure entre les têtes 22 de deux griffes 20 diamétralement opposées par rapport à l'axe A.The internal distance between the heads 32 of two vanes 30 diametrically opposite with respect to the axis A may also be substantially identical to the internal distance between the heads 22 of two claws 20 diametrically opposite with respect to the axis A, but against , it is not conceivable that the internal distance between the heads 32 of two vanes 30 diametrically opposite with respect to the axis A is greater than the internal distance between the heads 22 of two claws 20 diametrically opposite with respect to the axis AT.
Dans cette configuration, l'axe D passe à égale distance entre deux bases 22 des deux griffes 20 adjacente sur la périphérie de la couronne 28. Comme on peut le voir en figure 10, les griffes 20 ne se sont que très peu écartées lors du passage de l'appendice circulaire 40 du fait de leur rigidité, mais les palettes 30 se sont fortement écartées lors du passage de l'appendice circulaire 40 du fait de leur flexibilité. La figure 11 illustre par ailleurs une autre configuration possible pour le positionnement de l'axe de la partie distale de câblage C, nommé ici D'.In this configuration, the axis D passes equidistantly between two bases 22 of the two claws 20 adjacent to the periphery of the ring 28. As can be seen in FIG. 10, the claws 20 are only very slightly spaced apart during the passage of the circular appendage 40 because of their rigidity, but the vanes 30 are widely separated during the passage of the circular appendage. 40 because of their flexibility. FIG. 11 also illustrates another possible configuration for positioning the axis of the distal portion of wiring C, named here D '.
Dans cette configuration, l'axe D' passe au centre des bases 32 des deux palettes 30 diamétralement opposées par rapport à l'axe A.In this configuration, the axis D passes to the center of the bases 32 of the two vanes 30 diametrically opposite to the axis A.
En figure 12, la configuration de la figure 11 est illustrée coopérant avec un appendice 40 à section circulaire à une face 42 plate, c'est-à-dire à un pan. Cette face 42 est réalisée de telle manière que son plan soit parallèle à l'axe T de l'appendice.In FIG. 12, the configuration of FIG. 11 is illustrated cooperating with an appendix 40 having a circular section with a flat face 42, that is to say a panel. This face 42 is made in such a way that its plane is parallel to the axis T of the appendix.
La figure 13 illustre une configuration plus simple que celle de la figureFigure 13 illustrates a simpler configuration than that of the figure
9. Dans cette configuration de la figure 13, il n'y a que deux griffes 20 et deux palettes 30, les deux griffes étant diamétralement opposées par rapport à l'axe A et les deux palettes étant diamétralement opposées par rapport à l'axe A.9. In this configuration of FIG. 13, there are only two claws 20 and two vanes 30, the two claws being diametrically opposite with respect to the axis A and the two vanes being diametrically opposite with respect to the axis. AT.
Il se trouve en outre que les griffes et les palettes sont alternées sur le pourtour de la couronne 28 de telle sorte que l'angle entre une griffe et une palette adjacente sur le pourtour de la couronne soit toujours identique : de l'ordre de 45° .It is further found that the claws and the pallets are alternated around the periphery of the ring 28 so that the angle between a claw and an adjacent pallet on the periphery of the crown is always identical: of the order of 45 °.
En figure 14, la configuration de la figure 13 est illustrée coopérant avec un appendice 40 à section parallélépipédique et même plus précisément rectangulaire, présentant ainsi 4 faces plates. Ces faces sont réalisées de telle manière qu'elles sont toutes parallèles à l'axe T de l'appendice.In FIG. 14, the configuration of FIG. 13 is illustrated cooperating with an appendage 40 with a parallelepipedal section and even more precisely a rectangular section, thus having 4 flat faces. These faces are made in such a way that they are all parallel to the axis T of the appendix.
La figure 15 illustre une configuration plus complexe que celle de la figure 13. Dans cette configuration de la figure 15, il y a trois griffes 20 et trois palettes 30 et les griffes et les palettes ne sont pas diamétralement opposées deux à deux par rapport à l'axe A. Dans la configuration de la figure 15, les griffes 20 et les palettes 30 sont réparties angulairement de telle sorte que l'angle entre toutes les griffes 20 soit toujours identique et l'angle entre les palettes 30 soit toujours identique. Il se trouve en outre que les griffes et les palettes sont alternées sur le pourtour de la couronne 28 de telle sorte que l'angle entre une griffe et une palette adjacente sur le pourtour de la couronne soit toujours identique : de l'ordre de 30° .FIG. 15 illustrates a more complex configuration than that of FIG. 13. In this configuration of FIG. 15, there are three claws 20 and three vanes 30 and the claws and the vanes are not diametrically opposed two by two with respect to FIG. In the configuration of FIG. 15, the claws 20 and the vanes 30 are distributed angularly so that the angle between all the claws 20 is always the same and the angle between the pallets 30 is always the same. It is further found that the claws and pallets are alternated around the periphery of the ring 28 so that the angle between a claw and an adjacent pallet on the periphery of the crown is always the same: of the order of 30 °.
En figure 16, la configuration de la figure 15 est illustrée coopérant avec un appendice 40 à section hexagonale, présentant ainsi 6 faces plates. Ces faces sont réalisées de telle manière qu'elles sont toutes parallèles à l'axe T de l'appendice. La configuration de la figure 15 pourrait aussi, par exemple, coopérer avec un appendice 40 à section triangulaire, les trois faces plates coopérant avec les trois palettes et les trois griffes coopérant de manière ponctuelle avec les trois coins de l'appendice.In FIG. 16, the configuration of FIG. 15 is illustrated cooperating with an appendix 40 with a hexagonal section, thus presenting 6 flat faces. These faces are made in such a way that they are all parallel to the axis T of the appendix. The configuration of FIG. 15 could also, for example, cooperate with an appendix 40 with a triangular section, the three flat faces cooperating with the three pallets and the three claws cooperating pointwise with the three corners of the appendix.
La figure 17 illustre une configuration plus complexe que celle de la figure 15. Dans cette configuration de la figure 17, il y a quatre griffes 20 et quatre palettes 30 et les griffes et les palettes sont diamétralement opposées deux à deux par rapport à l'axe A.FIG. 17 illustrates a more complex configuration than that of FIG. 15. In this configuration of FIG. 17, there are four claws 20 and four vanes 30 and the claws and the vanes are diametrically opposed two by two with respect to FIG. axis A.
Dans la configuration de la figure 17 aussi, les griffes 20 et les palettes 30 sont réparties angulairement de telle sorte que l'angle entre toutes les griffes 20 soit toujours identique et l'angle entre les palettes 30 soit toujours identique. Il se trouve en outre que les griffes et les palettes sont alternées sur le pourtour de la couronne 28 de telle sorte que l'angle entre une griffe et une palette adjacente sur le pourtour de la couronne soit toujours identique : de l'ordre de 22,5° . En figure 18, la configuration de la figure 17 est illustrée coopérant avec un appendice 40 à section octogonale, présentant ainsi 8 faces plates. Ces faces sont réalisées de telle manière qu'elles sont toutes parallèles à l'axe T de l'appendice.In the configuration of Figure 17 also, the claws 20 and the pallets 30 are angularly distributed so that the angle between all the claws 20 is always the same and the angle between the pallets 30 is always the same. It is further found that the claws and pallets are alternated around the periphery of the ring 28 so that the angle between a claw and an adjacent pallet on the periphery of the crown is always identical: of the order of 22 , 5 °. In FIG. 18, the configuration of FIG. 17 is illustrated cooperating with an appendage 40 with an octagonal section, thus having 8 flat faces. These faces are made in such a way that they are all parallel to the axis T of the appendix.
La configuration de la figure 17 pourrait aussi, par exemple, coopérer avec un appendice 40 à section rectangulaire, les quatre faces plates coopérant avec les quatre palettes et les quatre griffes coopérant de manière ponctuelle avec les quatre coins de l'appendice.The configuration of FIG. 17 could also, for example, cooperate with an appendage 40 with a rectangular section, the four flat faces cooperating with the four pallets and four claws cooperating punctually with the four corners of the appendix.
Dans la configuration de la figure 19, la connexion électrique 1 est formée d'un connecteur électrique mâle selon la revendication 10 et d'un connecteur électrique femelle qui n'est pas selon la revendication 1.In the configuration of FIG. 19, the electrical connection 1 is formed of a male electrical connector according to claim 10 and a female electrical connector which is not according to claim 1.
Le connecteur électrique mâle présente deux appendices 40, 40' orientés chacun selon un axe central T, T' et chaque appendice 40, 40' présente une face 42, 42' plate. Le connecteur électrique femelle présente deux parties distales de câblage C, C et deux parties proximales de branchement comportant chacune une ouverture présentant une forme générale de couronne 28, 28' et orientée chacune selon un axe central A, A'.The male electrical connector has two appendages 40, 40 'each oriented along a central axis T, T' and each appendix 40, 40 'has a flat face 42, 42'. The female electrical connector has two distal wiring portions C, C and two proximal connection portions each having an opening having a generally ring-shaped 28, 28 'and each oriented along a central axis A, A'.
La distance S entre les deux faces 42, 42' plates est supérieure à la somme de la largeur 128, 128' de deux couronnes 28, 28' ; cette distance S est même ici supérieur au double de la somme des largeurs 128, 128'.The distance S between the two flat faces 42, 42 'is greater than the sum of the width 128, 128' of two rings 28, 28 '; this distance S is even greater than twice the sum of the widths 128, 128 '.
Ces deux faces 42, 42' ne sont pas parallèles entre elles et sont orientés d'un angle δ > à 10 ° et < 80 ° .These two faces 42, 42 'are not parallel to each other and are oriented at an angle δ> at 10 ° and <80 °.
La figure 19 illustre par ailleurs le fait que les axes D, D' des partie distale de câblage C, C du connecteur électrique femelle ne sont pas parallèles et sont orientés du même angle δ.FIG. 19 also illustrates that the axes D, D 'of the distal wiring portion C, C of the female electrical connector are not parallel and are oriented at the same angle δ.
Lors de l'utilisation de la configuration présentée ci-avant en référence aux figures 1 à 9 et 14, il a été constaté que l'effort moyen d'insertion du connecteur électrique femelle 2 sur le connecteur électrique mâle 4 était deWhen using the configuration presented above with reference to Figures 1 to 9 and 14, it was found that the average insertion force of the female electrical connector 2 on the male electrical connector 4 was
54,4 N et que l'effort moyen d'extraction du connecteur électrique femelle 1 du connecteur électrique mâle 4 était de 90,6 N.54.4 N and that the average extraction force of the female electrical connector 1 of the male electrical connector 4 was 90.6 N.
L'effort d'extraction du connecteur électrique femelle 2 du connecteur électrique mâle 4 est ainsi ici d'environ 1 ,66 fois supérieur à l'effort d'insertion du connecteur électrique femelle 2 sur le connecteur électrique mâle 4. Tant le connecteur électrique femelle 2 que le connecteur électrique mâle 4 sont fabriqués à partir d'une matière conductrice d'électricité, comme par exemple du bronze CuSn9PH12.The extraction force of the female electrical connector 2 of the male electrical connector 4 is thus about 1.66 times greater than the insertion force of the female electrical connector 2 on the male electrical connector 4. Both the female electrical connector 2 and the male electrical connector 4 are made from an electrically conductive material, such as bronze CuSn9PH12.
La présente invention est décrite dans ce qui précède à titre d'exemple.The present invention is described in the foregoing by way of example.
