Description

La présente invention concerne un ensemble d'éléments de transmission de force ou plongeurs pour module de commande à commutateur en translation.The present invention relates to a set of force transmission elements or plungers for a translation switch control module.

EP 2 009 662 A1 divulgue un élément de transmission de force d'enfoncement entre un corps de commutateur et un nombre N entier supérieur ou égal à 2 de commutateurs électroniques disposés sur les extrémités d'un segment ou les sommets d'un polygone, comportant plongeurs mobiles en translation selon un axe d'enfoncement du corps de commutateur, et un cadre souple reliant les plongeurs, le cadre comporte pour chaque plongeur une portion de contournement entourant chacune partiellement le plongeur associé. EP 2 009 662 A1 discloses an element for transmitting a driving force between a switch body and an integer number N greater than or equal to 2 of electronic switches arranged on the ends of a segment or the vertices of a polygon, comprising plungers movable in translation according to a push-in pin for the switch body, and a flexible frame connecting the plungers, the frame comprises for each plunger a bypass portion each partially surrounding the associated plunger.

Les éléments de transmission de force sont utilisés dans les modules de commande à commutateurs en translation ou croix directionnelles pour transmettre la force exercée par l'utilisateur sur un corps de bouton et un commutateur électronique. Le corps de bouton est apparent, décoré et généralement du même matériau qu'une enveloppe externe du module de commande. Le commutateur électronique est situé sous le corps de bouton, généralement sur un circuit imprimé situé au niveau d'un fond du module.The force transmission elements are used in control modules with translational switches or directional crosses to transmit the force exerted by the user on a button body and an electronic switch. The button body is exposed, decorated and generally of the same material as an outer shell of the control module. The electronic switch is located under the button body, generally on a printed circuit located at a bottom of the module.

Le corps de bouton est l'élément avec lequel l'utilisateur interagit, tandis que le commutateur électronique génère le signal électronique qui déclenchera la prise en compte de l'enfoncement du corps de bouton.The button body is the element with which the user interacts, while the electronic switch generates the electronic signal which will trigger the recognition of the depression of the button body.

Pour plus de facilité et de rapidité à l'assemblage, il est connu de réaliser les éléments de transmission de force, aussi appelés « plongeurs », de façon solidaires entre eux au moyen d'un cadre les reliant. Lors de l'assemblage, l'ensemble de plongeurs peut alors être manipulé comme un seul élément. Le cadre est généralement en matériau plastique souple, souvent le même que les plongeurs, avec lesquels il vient de matière. La souplesse du cadre vient alors de l'épaisseur plus faible de plastique du cadre par rapport aux plongeurs, qui restent relativement rigides.For greater ease and speed in assembly, it is known to produce the force transmission elements, also called "plungers", integral with one another by means of a frame connecting them. During assembly, the plunger set can then be handled as a single unit. The frame is generally made of a flexible plastic material, often the same as the divers, with which it comes integral. The flexibility of the frame then comes from the thinner plastic of the frame compared to the plungers, which remain relatively rigid.

Lorsque les plongeurs sont proches les uns des autres, typiquement à moins de quelques centimètres (cm) de distance, le cadre qui les relie peut transmettre les forces et déformations. Ainsi, l'enfoncement d'un plongeur actionné par l'utilisateur peut entraîner un ou plusieurs plongeurs adjacents. Dès lors, l'actionnement d'un commutateur par l'utilisateur peut entraîner la prise en compte non-désirée d'un actionnement des commutateurs adjacents.When divers are close to each other, typically less than a few centimeters (cm) apart, the frame that connects them can transmit forces and deformations. Thus, the depression of a user-actuated plunger may cause one or more adjacent plungers. Therefore, the actuation of a switch by the user can cause the unwanted taking into account of an actuation of adjacent switches.

Ce cas de figure est en particulier rencontré dans les modules de commande à croix directionnelle, par exemple pour le contrôle de l'inclinaison d'un rétroviseur latéral. Dans une croix directionnelle, l'utilisateur incline un corps de bouton relativement plan circulaire ou cruciforme dans des directions orthogonales ou diagonales. Des commutateurs électroniques, généralement quatre, huit ou seize, sont alors enfoncés par des plongeurs en nombre correspondant qui transmettent la force appliquée par l'utilisateur sur le corps de bouton.This scenario is encountered in particular in control modules with a directional cross, for example for controlling the inclination of a side mirror. In a directional cross, the user tilts a relatively planar circular or cruciform button body in orthogonal or diagonal directions. Electronic switches, generally four, eight or sixteen, are then depressed by corresponding number of plungers which transmit the force applied by the user to the button body.

Pour éviter la transmission de force à un plongeur adjacent, il est possible d'amincir le cadre, ce qui le rend plus souple mais aussi plus fragile à la manipulation, ou bien de changer la composition du matériau le composant. Cependant le matériau choisi est souvent optimisé en termes de rigidité et de coût pour les plongeurs, le cadre ne servant qu'au maintien et à la mise en place des plongeurs à l'assemblage.To avoid the transmission of force to an adjacent plunger, it is possible to thin the frame, which makes it more flexible but also more fragile to handling, or else to change the composition of the material composing it. However, the material chosen is often optimized in terms of rigidity and cost for the divers, the frame only being used for the maintenance and the positioning of the divers for assembly.

Afin de résoudre au moins partiellement le problème précédemment mentionné, l'invention a pour objet un élément de transmission de force d'enfoncement entre un corps de commutateur et un nombre N entier supérieur ou égal à 2 de commutateurs électroniques disposés sur les extrémités d'un segment ou les sommets d'un polygone, comportant N plongeurs mobiles en translation selon un axe d'enfoncement du corps de commutateur, et un cadre souple reliant les N plongeurs, le cadre comporte :

  • ∘ pour chaque plongeur une portion de contournement entourant chacune partiellement le plongeur associé,
  • ∘ des portions de liaison reliant deux-à-deux les portions de contournement de sorte à former un cadre extérieur fermé,
  • ∘ des poutrelles de commande portant sur une extrémité libre un plongeur, et reliées par l'autre extrémité à la portion de contournement d'un plongeur adjacent en suivant le polygone selon un sens prédéterminé.
In order to at least partially resolve the previously mentioned problem, the invention relates to an element for transmitting a driving force between a switch body and an integer number N greater than or equal to 2 of electronic switches arranged on the ends of the switches. a segment or the vertices of a polygon, comprising N movable plungers in translation along an axis of depression of the switch body, and a flexible frame connecting the N plungers, the frame comprises:
  • ∘ for each diver a bypass portion each partially surrounding the associated diver,
  • ∘ connecting portions connecting the bypass portions two by two so as to form a closed outer frame,
  • ∘ control beams bearing on a free end a plunger, and connected by the other end to the bypass portion of an adjacent plunger by following the polygon in a predetermined direction.

L'élément de transmission de force ainsi obtenu permet de diminuer le couplage en translation entre les différents plongeurs, sans diminuer la compacité de l'ensemble.The force transmission element thus obtained makes it possible to reduce the translational coupling between the different plungers, without reducing the compactness of the assembly.

Les poutrelles de liaison comprennent des circonvolutions les rallongeant.The connecting beams include convolutions lengthening them.

La figure 1 montre de façon schématique en éclaté un module de commande 1.

The control module 1 is in particular intended to be placed in a vehicle interior to allow for example the adjustment of the orientation of an exterior mirror mirror of the vehicle.

Le polygone P est donc dans le cas présent un parallélogramme, en particulier un losange, et plus spécifiquement un carré.From the top view it can be seen that the plungers 7 are arranged on the vertices of a polygon P, the number N of sides of which corresponds to the number of main directions of inclination, here four, and therefore to the number of plungers 7 and of electronic switches 11. Polygon P is therefore in the present case a parallelogram, in particular a rhombus, and more specifically a square.

La forme carrée du polygone P découle ici de la forme discoïde circulaire du corps de commutateur 3. Si le corps de commutateur 3 est en particulier allongé dans une direction (forme ovale ou en losange étiré), le polygone P peut être étiré en conséquence et donc être un losange ou un parallélogramme.The square shape of the polygon P here derives from the circular discoid shape of the switch body 3. If the switch body 3 is especially elongated in one direction (oval or diamond-shaped stretched), the polygon P can be stretched accordingly and therefore be a rhombus or a parallelogram.

Les plongeurs 7 sont reliés entre eux par un cadre 9 venant de matière avec eux. En particulier, dans le cas de plongeurs 7 en matériau plastique moulé, le cadre est obtenu lors du moulage, l'élément de transmission de force avec ses N plongeurs, où N est le nombre de directions principales d'inclinaison du corps de commutateur 3, et le cadre 9 est alors obtenu d'une seule pièce. Les matériaux utilisés peuvent notamment comporter du polyéthylène, du polyester, du polyuréthane, du caoutchouc, en particulier réticulé.The plungers 7 are connected to each other by a frame 9 integral with them. In particular, in the case of plungers 7 of molded plastic material, the frame is obtained during molding, the force transmitting element with its N plungers, where N is the number of main directions of inclination of the switch body 3 , and the frame 9 is then obtained in one piece. The materials used can in particular include polyethylene, polyester, polyurethane, rubber, in particular crosslinked.

Le cadre 9 comporte des portions allongées, de section faible par rapport aux plongeurs 7. Les plongeurs 7 ont généralement une section rectangulaire, avec des côtés variant typiquement de deux à cinq millimètres (2-5mm), les sections des portions allongées du cadre 9 étant circulaires ou rectangulaire, avec un côté ou un diamètre typiquement de l'ordre de un demi à un millimètre (0,5-1 mm). Cette différence de dimensionnement permet aux plongeurs 7 d'être relativement rigides tandis que le cadre 9 est souple, les deux étant constitué du même matériau plastique.The frame 9 comprises elongated portions, of small section compared to the plungers 7. The plungers 7 generally have a rectangular section, with sides typically varying from two to five millimeters (2-5mm), the sections of the elongated portions of frame 9 being circular or rectangular, with one side or diameter typically of the order of one-half to one millimeter (0.5 -1 mm). This difference in dimensioning allows the plungers 7 to be relatively rigid while the frame 9 is flexible, both being made of the same plastic material.

Le cadre 9 comporte quatre portions de contournement 13 entourant chacune partiellement un plongeur 7. Les portions de contournement 13 sont ici réalisées sous forme de portions de cercle, ouvertes sur l'intérieur du polygone P. D'autres modes de réalisation peuvent comporter des portions de contournement 13 de forme polygonale.The frame 9 comprises four bypass portions 13 each partially surrounding a plunger 7. The bypass portions 13 are here produced in the form of portions of a circle, open to the inside of the polygon P. Other embodiments may include portions bypass 13 of polygonal shape.

Le cadre 9 comporte aussi quatre portions de liaison 15 reliant deux-à-deux les portions de contournement 13 consécutives sur le polygone P de sorte à former un cadre extérieur fermé, ici de forme générale carrée, dont les angles sont arrondis par la présence des portions de contournement 13 entourant partiellement les plongeurs 7.The frame 9 also comprises four connecting portions 15 connecting two by two the consecutive bypass portions 13 on the polygon P so as to form a closed outer frame, here of generally square shape, the angles of which are rounded by the presence of bypass portions 13 partially surrounding the plungers 7.

Les portions de contournement 13 se prolongent vers l'intérieur du polygone P à partir des portions de liaison 15 reliant deux-à-deux lesdites portions de contournement 13. Le cadre 9 comporte aussi quatre poutrelles de commande 17 reliant un plongeur 7 déterminé à la portion de contournement 13 entourant partiellement le plongeur 7 suivant en longeant le polygone P selon un sens prédéterminé, ici le sens horaire. Ces poutrelles de commande 17 relient donc un n-ième plongeur 7, avec n entier entre 1 et N, où N est le nombre de plongeurs 7, à la portion de contournement 13 entourant partiellement le n+1-ième plongeur, en suivant le polygone P, selon un sens de rotation prédéterminé, la N-ième poutrelle de commande 17 étant reliée à la portion de contournement entourant le premier plongeur 7.The bypass portions 13 extend towards the interior of the polygon P from the connecting portions 15 connecting two by two said bypass portions 13. The frame 9 also comprises four control beams 17 connecting a plunger 7 determined to the bypass portion 13 partially surrounding the next plunger 7 along the polygon P in a predetermined direction, here clockwise. These control beams 17 therefore connect an n- th plunger 7, with n integer between 1 and N, where N is the number of plungers 7, to the bypass portion 13 partially surrounding the n + 1-th plunger, following the polygon P, in a predetermined direction of rotation, the N th order beam 17 being connected to the bypass portion surrounding the first plunger 7.

Les portions de liaison 15 et les poutrelles de commande 17 sur un même côté du polygone P sont ici rectilignes et parallèles entre elles et au côté du polygone P auquel elles correspondent. Pour une meilleure compréhension, les différentes portions du cadre 9 sont, en figure 2, délimitées par des segments pointillés.The connecting portions 15 and the control beams 17 on the same side of the polygon P are here rectilinear and parallel to each other and to the side of the polygon P to which they correspond. For a better understanding, the different portions of the frame 9 are, in figure 2 , delimited by dotted segments.

La figure 3 montre un autre mode de réalisation d'élément de transmission de force 5, et en particulier du cadre 9 portant les plongeurs 7, est représenté en vue de dessus en figure 3.The figure 3 shows another embodiment of the force transmission element 5, and in particular of the frame 9 carrying the plungers 7, is shown in top view in figure 3 .

Le mode de réalisation de la figure 3 diffère de celui de la figure 2 en ce que les portions de liaison 15 reliant deux-à-deux les portions de contournement 13 entourant les plongeurs 7, et les poutrelles de commande 17 reliant un plongeur 7 à la portion de contournement 13 entourant le plongeur 7 suivant, comportent des circonvolutions qui augmentent leur longueur effective.The embodiment of the figure 3 differs from that of figure 2 in that the connecting portions 15 connecting two by two the bypass portions 13 surrounding the plungers 7, and the control beams 17 connecting a plunger 7 to the bypass portion 13 surrounding the next plunger 7, comprise convolutions which increase their effective length.

Les portions de liaison 15 reliant deux-à-deux les portions de contournement 13 entourant les plongeurs 7 sont ici en forme de « s ». Lesdites portions de liaison 15 s'étirent dans le prolongement des portions 13 entourant les plongeurs 7, décrivent une courbe convexe vers l'intérieur du polygone P, suivie d'une courbe concave vers l'intérieur du polygone P. Lesdites portions de liaison 15 rejoignent ensuite la portion de contournement 13 entourant le plongeur 7 avec un raccord en angle droit.The connecting portions 15 connecting two by two the bypass portions 13 surrounding the plungers 7 are here in the shape of " s ". Said connecting portions 15 stretch in the extension of the portions 13 surrounding the plungers 7, describe a curve convex towards the interior of the polygon P, followed by a concave curve towards the interior of the polygon P. The said connecting portions 15 then join the bypass portion 13 surrounding the plunger 7 with a right angle connection.

Les poutrelles de commande 17 reliant un plongeur 7 à la portion de contournement 13 entourant le plongeur 7 suivant suivent un tracé parallèle aux portions de liaison 15 reliant deux-à-deux les portions de contournement 13 entourant les plongeurs 7, le raccord desdites poutrelles de commande 17 à la portion de contournement 13 entourant le plongeur 7 suivant se faisant dans le prolongement continu de ladite portion de contournement 13.The control beams 17 connecting a plunger 7 to the bypass portion 13 surrounding the next plunger 7 follow a path parallel to the connecting portions 15 connecting two by two the bypass portions 13 surrounding the plungers 7, the connection of said beams of control 17 to the bypass portion 13 surrounding the next plunger 7 being in the continuous extension of said bypass portion 13.

L'augmentation de la longueur effective des portions de liaison 15, 17 du cadre permet d'augmenter le débattement d'un plongeur 7 sans que les plongeurs 7 adjacents ne soient entraînés.The increase in the effective length of the connecting portions 15, 17 of the frame makes it possible to increase the travel of a plunger 7 without the adjacent plungers 7 being driven.

La forme de la figure 3 permet aussi de réduire le nombre de coudes formant raccords entre les différentes portions 13, 15, 17. En effet, les coudes, du fait de la variation brutale de largeur de matériau qu'ils représentent, sont autant de zones de concentration de contraintes, et donc de points de rupture potentiels lors des déformations.The shape of the figure 3 also makes it possible to reduce the number of elbows forming connections between the different portions 13, 15, 17. In fact, the elbows, due to the sudden variation in width of material that they represent, are as many areas of stress concentration, and therefore potential breaking points during deformations.

Les figures 4a et 4b illustrent le fonctionnement d'un module de commande 1 comportant un élément de transmission de force 5 tel que précédemment décrit. Les figures 4a, 4b sont des vues en coupe latérales d'un module de commande 1, respectivement en l'absence d'actionnement et en cours d'actionnement.The figures 4a and 4b illustrate the operation of a control module 1 comprising a force transmission element 5 as described above. The figures 4a, 4b are side sectional views of a control module 1, respectively in the absence of actuation and in the course of actuation.

Dans le mode de réalisation de la figure 4a, le corps de commutateur 3 est articulé autour d'une liaison rotule 19, permettant une inclinaison dudit corps de commutateur 3 par rapport à une paroi 21 formant logement. La liaison rotule 19 comporte en particulier des moyens de rappel élastique, qui assurent un retour à une position neutre du corps de commutateur 3 en l'absence d'actionnement par l'utilisateur.In the embodiment of the figure 4a , the switch body 3 is articulated around a ball joint 19, allowing said switch body 3 to be tilted relative to a wall 21 forming a housing. The ball joint 19 comprises in particular elastic return means, which ensure a return to a neutral position of the switch body 3 in the absence of actuation by the user.

Les plongeurs 7, dont deux sont visibles en figure 4a, sont situés dans des logements cylindriques 23 formant guidage en translation des plongeurs 7. Les logements cylindriques 23 sont situés sous les directions principales d'inclinaison du corps de commutateur 3. Les plongeurs 7 sont reliés entre eux par un cadre 9 souple tel que décrit en figure 3. Les plongeurs 7 et le cadre 9 formant l'élément de transmission de force 5 sont représentés hachurés dans les figures 4a et 4b pour une meilleure compréhension.7 divers, two of which are visible in figure 4a , are located in cylindrical housings 23 forming translational guidance of the plungers 7. The cylindrical housings 23 are located under the main directions of inclination of the switch body 3. The plungers 7 are interconnected by a flexible frame 9 as described. in figure 3 . The plungers 7 and the frame 9 forming the force transmission element 5 are shown hatched in the figures 4a and 4b for a better understanding.

Les plongeurs 7 sont raccordés au cadre 9 par des plateaux circulaires 25, dont la forme et la taille correspond à celle des commutateurs électroniques 11 situés sous lesdits plateaux 25 sur un circuit imprimé 27.The plungers 7 are connected to the frame 9 by circular plates 25, the shape and size of which corresponds to that of the electronic switches 11 located under said plates 25 on a printed circuit 27.

En figure 4b, un utilisateur applique une force F sur le côté gauche du corps de commutateur 3, de sorte que celui ci est incliné à gauche par rotation autour de la liaison rotule 19. En conséquence, le plongeur 7 à gauche en figure 4b est abaissé d'un déplacement δ, et comprime donc le commutateur électronique 11 situé en dessous.In figure 4b , a user applies a force F to the left side of the switch body 3, so that the latter is tilted to the left by rotation around the ball joint 19. As a result, the plunger 7 on the left in figure 4b is lowered by a displacement δ, and therefore compresses the electronic switch 11 located below.

La compression du commutateur électronique 11 déclenche l'émission d'un signal électronique logique, qui est pris en compte par une unité de contrôle du véhicule. L'unité de contrôle du véhicule modifie alors le fonctionnement d'un module fonctionnel (phares, climatisation, lève-vitre, lecteur multimédia) du véhicule en conséquence.The compression of the electronic switch 11 triggers the transmission a logical electronic signal, which is taken into account by a vehicle control unit. The vehicle control unit then modifies the operation of a functional module (headlights, air conditioning, window regulator, multimedia player) of the vehicle accordingly.

Si le module de commande 1 est utilisé pour contrôler l'orientation d'un rétroviseur, l'inclinaison du corps de commutateur 3 à gauche déclenche la mise en marche d'un moteur électrique qui incline le rétroviseur dans la direction correspondante.If the control module 1 is used to control the orientation of a mirror, tilting the switch body 3 to the left triggers the start of an electric motor which tilts the mirror in the corresponding direction.

Les figures 5 et 6 illustrent d'autres modes de réalisation d'élément de transmission de force 5, avec un nombre N de plongeurs 7 différent de quatre.The figures 5 and 6 illustrate other embodiments of force transmission element 5, with a number N of plungers 7 other than four.

En figure 5, le nombre N de plongeurs vaut deux (N = 2). Les plongeurs 7 sont donc situés aux extrémités d'un segment S au lieu des sommets d'un polygone P.In figure 5 , the number N of divers is equal to two ( N = 2). The plungers 7 are therefore located at the ends of a segment S instead of the vertices of a polygon P.

Ce mode de réalisation est donc adapté au contrôle de l'ouverture et de la fermeture d'une fenêtre de portière du véhicule, avec deux directions d'actionnement : haut U et bas D correspondant respectivement à la fermeture et à l'ouverture de la fenêtre.This embodiment is therefore suitable for controlling the opening and closing of a vehicle door window, with two actuation directions: up U and down D corresponding respectively to the closing and opening of the door. window.

Le cadre 9 comporte en particulier deux (N) portions de contournement 13 entourant les plongeurs 7, deux (N) portions de liaison 15 reliant deux-à-deux lesdites portions de contournement 13, et deux (N) poutrelles de commande 17 reliant un plongeur 7 à la portion de contournement 13 entourant le plongeur 7 suivant.The frame 9 comprises in particular two ( N ) bypass portions 13 surrounding the plungers 7, two ( N ) connecting portions 15 connecting two by two said bypass portions 13, and two ( N ) control beams 17 connecting a plunger 7 to the bypass portion 13 surrounding the next plunger 7.

En figure 6, le nombre N de plongeurs vaut huit (N = 8). Les plongeurs 7 sont situés aux sommets du polygone P qui est ici un octogone, en particulier un octogone régulier.In figure 6 , the number N of divers is equal to eight ( N = 8). The plungers 7 are located at the vertices of the polygon P which is here an octagon, in particular a regular octagon.

Ce mode de réalisation comporte donc des plongeurs 7 pour les quatre directions haut U, bas D, gauche L, droite R telles que décrites en rapport avec les figures 1, 2, 3, 4a et 4b, ainsi que pour les quatre directions diagonales.This embodiment therefore includes plungers 7 for the four directions up U, down D, left L, right R as described in relation to the figures 1, 2, 3 , 4a and 4b , as well as for the four diagonal directions.

Le cadre 9 comporte en particulier huit (N) portions de contournement 13 entourant les plongeurs 7, huit (N) portions de liaison 15 reliant deux-à-deux lesdites portions de contournement 13, et huit (N) poutrelles de commande 17 reliant un plongeur 7 à la portion de contournement 13 entourant le plongeur 7 suivant.The frame 9 comprises in particular eight ( N ) bypass portions 13 surrounding the plungers 7, eight ( N ) connecting portions 15 connecting two by two said bypass portions 13, and eight ( N ) control beams 17 connecting a plunger 7 to the bypass portion 13 surrounding the next plunger 7.

D'autres modes de réalisations avec un nombre N différent de plongeurs 7, de portions de contournement 13 entourant les plongeurs 7, de portions de liaison 15 reliant deux-à-deux lesdites portions de contournement 13 et les poutrelles de commande 1. Un nombre N grand (huit, douze ou seize) permet de différencier plus finement l'inclinaison du corps de commutateur 3 mais diminue la compacité du module de commande 1 final.Other embodiments with a different number N of plungers 7, of bypass portions 13 surrounding the plungers 7, of connecting portions 15 connecting two by two said bypass portions 13 and the control beams 1. A number N large (eight, twelve or sixteen) makes it possible to differentiate more finely the inclination of the switch body 3 but reduces the compactness of the final control module 1.

Les modes de réalisation avec deux et quatre plongeurs 7, avec le cadre 9 correspondant, sont indiqués dans la réalisation d'un dispositif de commande implémenté dans un accoudoir ou une portière de voiture, afin de contrôler l'ouverture et la fermeture d'une fenêtre de la portière, et de contrôler l'orientation d'un rétroviseur disposé au niveau de ladite portière.The embodiments with two and four plungers 7, with the corresponding frame 9, are shown in the embodiment of a control device implemented in an armrest or a car door, in order to control the opening and closing of a door window, and to control the orientation of a rear-view mirror disposed at said door.

Le cadre 9 de l'élément de transmission de force 5 selon l'invention permet de réduire le couplage en translation des différents plongeurs 7, tout en venant de matière avec lesdits plongeurs 7, en particulier par moulage dans un même moule. L'élément de transmission de force 5 obtenu est donc de faible coût de revient tout en étant compact et aisément manipulable.The frame 9 of the force transmission element 5 according to the invention makes it possible to reduce the translational coupling of the different plungers 7, while being integral with said plungers 7, in particular by molding in the same mold. The force transmission element 5 obtained is therefore of low production cost while being compact and easy to handle.
