Description

Domaine de l'inventionField of the invention

L'invention concerne une un objet portable comportant au moins une carrure et un fond pour renfermer un module électronique, ledit module électronique comportant une platine munie d'un logement agencé pour la réception d'un accumulateur d'énergie électrique, ledit module électronique comportant au moins un circuit avec au moins une zone de contact électrique, et un organe de contact de liaison pour assurer une liaison électrique entre ledit accumulateur et ladite au moins une zone de contact, ledit organe de contact de liaison étant déformable élastiquement.The invention relates to a portable object comprising at least a middle and a bottom for enclosing an electronic module, said electronic module comprising a plate provided with a housing arranged for receiving an accumulator of electrical energy, said electronic module comprising at least one circuit with at least one electrical contact area, and a contact contact member for providing an electrical connection between said accumulator and said at least one contact area, said connecting contact member being resiliently deformable.

L'invention concerne encore une pièce d'horlogerie comportant au moins une telle structure.The invention also relates to a timepiece comprising at least one such structure.

L'invention concerne le domaine de l'horlogerie, et en particulier le domaine des montres comportant au moins un circuit électronique ou électrique alimenté par un accumulateur tel qu'une pile ou similaire. L'invention concerne plus particulièrement la liaison mécanique et électrique entre un accumulateur et un circuit, de part et d'autre d'une platine.The invention relates to the field of watchmaking, and in particular the field of watches comprising at least one electronic or electrical circuit powered by an accumulator such as a battery or the like. The invention relates more particularly to the mechanical and electrical connection between an accumulator and a circuit, on either side of a plate.

Arrière-plan de l'inventionBackground of the invention

La qualité des contacts électriques dans une montre doit être assurée en permanence, dans toute configuration d'utilisation, et notamment d'accélération ou de choc. Tout particulièrement, la permanence de l'alimentation électrique depuis un accumulateur, en général une pile, rend nécessaire une très bonne connexion entre les pôles de cet accumulateur et le ou les circuits d'utilisation. On connaît notamment la fixation d'une pile dans un logement constitué par des languettes de ressort, qui maintiennent la pile tout en assurant le contact sur un de ses pôles. Le contact à l'autre pôle est effectué couramment par un connecteur souple, ou, de préférence, par une patte faisant ressort, fixée par vis ou rivets à une platine.The quality of the electrical contacts in a watch must be ensured permanently, in any configuration of use, including acceleration or shock. In particular, the permanence of the power supply from an accumulator, usually a battery, makes it necessary a very good connection between the poles of this accumulator and the circuit or circuits of use. It is in particular known to fix a battery in a housing constituted by spring tongues, which hold the battery while ensuring contact on one of its poles. The contact at the other pole is commonly performed by a flexible connector, or, preferably, by a spring tab, fixed by screws or rivets to a plate.

Du côté des circuits d'utilisation, on connaît les contacts réalisés par des connecteurs souples soudés, par des barrettes enfichables, ou par des pattes ressort appuyées sur le circuit, également par vis, rivet ou similaire, ou bien constituant de petits cavaliers pinçant le circuit sur l'épaisseur de sa tranche.On the side of the circuits of use, the contacts made by welded flexible connectors, by plug-in strips, or by spring tabs supported on the circuit, also by screws, rivets or the like, or constituting small riders pinching the circuit on the thickness of its slice.

Pour réaliser un contact permanent de qualité, avec le nombre le plus réduit de composants, on connaît encore , par exemple par le document JP11-281 776 au nom de MIYOTA, un ressort comportant deux bras, dont l'un prend appui sur un circuit, et l'autre prend appui sur une pile, ce dernier pouvant être maintenu par un fond de la montre.To achieve permanent quality contact, with the smallest number of components, it is still known, for example by the document JP11-281 776 MIYOTA, a spring with two arms, one of which is supported on a circuit, and the other is supported on a stack, the latter can be maintained by a bottom of the watch.

Toutefois, ces appuis sont de même sens, et l'appui permanent de la patte de ressort sur le circuit n'est pas garanti. Ainsi, lors d'un choc ou d'un mouvement brusque, il est possible que la patte de ressort ne fasse plus appui. Une telle disposition nécessite par ailleurs une liaison mécanique dédiée à l'assemblage du circuit sur une platine porteuse de la pile.However, these supports are the same direction, and the permanent support of the spring tab on the circuit is not guaranteed. Thus, during a shock or a sudden movement, it is possible that the spring tab is no longer support. Such an arrangement also requires a mechanical connection dedicated to the assembly of the circuit on a carrier plate of the battery.

Résumé de l'inventionSummary of the invention

L'invention a pour but de pallier les inconvénients de l'art antérieur en proposant de fournir un objet portable muni d'un élément de liaison électrique entre l'accumulateur électrique et le circuit électronique monté sur une platine permettant une liaison électrique permanente et qui permet également le maintien d'un accumulateur de grande taille dans ladite platine.The invention aims to overcome the drawbacks of the prior art by proposing to provide a portable object provided with an electrical connection element between the electric accumulator and the electronic circuit mounted on a plate for a permanent electrical connection and which also allows the maintenance of a large accumulator in said platen.

characterized in that said connecting contact member is formed of a shaped blade having a central portion at the ends of which extend at least a first arm and a second converging arm arranged to clamp said electronic module and thereby maintain said accumulator of electrical energy in its housing.

Description détaillée des modes de réalisation préférésDetailed Description of the Preferred Embodiments

L'invention concerne le domaine de l'horlogerie, et en particulier le domaine des montres comportant au moins un circuit électronique ou électrique alimenté par un accumulateur tel qu'une pile ou similaire. L'invention concerne plus particulièrement la liaison mécanique et électrique enter un accumulateur et un circuit, de part et d'autre d'une platine. En particulier, il s'agit, dans une montre, d'assurer en toute circonstance le contact entre le plus de la pile et le fond de la boîte.The invention relates to the field of watchmaking, and in particular the field of watches comprising at least one electronic or electrical circuit powered by an accumulator such as a battery or the like. The invention relates more particularly to the mechanical and electrical connection between an accumulator and a circuit, on either side of a plate. In particular, it is, in a watch, to ensure in all circumstances the contact between the plus of the battery and the bottom of the box.

L'invention, visible à a figure 1, concerne une structure 1 de pièce d'horlogerie 100, notamment une montre, comportant au moins une carrure 2 et un fond 3 pour renfermer un module 10 électronique ou électrique. Ce module 10 électronique envoie des informations vers un module d'affichage.The invention, visible at a figure 1 relates to a structure 1 of timepiece 100, including a watch, comprising at least a middle 2 and a bottom 3 for enclosing an electronic or electrical module 10. This electronic module sends information to a display module.

Ce module 10 comporte lui-même une platine 4 dont un compartiment ou logement 41 est agencé pour la réception d'un accumulateur d'énergie électrique 5, notamment une pile. La platine 4 peut être agencée pour que le compartiment 41, dans lequel l'accumulateur d'énergie électrique est placé, occupe la quasi-totalité de la surface de la platine 4. Par exemple, il est envisageable que le compartiment 41 de la platine 4 occupe toute la surface de cette dernière à l'exception d'une partie périphérique 42 définissant ledit compartiment 41 comme visible à la figure 6. Cela permet à l'objet portable de fonctionner à l'aide d'un accumulateur d'énergie électrique de plus grande taille et donc potentiellement plus puissant ou ayant une durée de vie plus importante. Ce module 10 comporte encore au moins un circuit 6 avec au moins une zone de contact 7 électrique, et un organe de contact de liaison 8 pour assurer une liaison électrique entre un accumulateur 5 et une zone de contact 7. Cet organe de contact de liaison 8 est déformable élastiquement de sorte que lorsqu'il subit une contrainte le déformant, sa capacité élastique tend à le ramener à une géométrie de repos. Dans une version préférée mais non limitative de l'invention, cet organe de contact de liaison 8 est entièrement élastique et est réalisé sous la forme d'un ressort.This module 10 itself comprises a plate 4, a compartment or housing 41 is arranged for receiving an electric energy accumulator 5, including a battery. The plate 4 can be arranged so that the compartment 41, in which the electric energy accumulator is placed, occupies almost the entire surface of the plate 4. For example, it is conceivable that the compartment 41 of the plate 4 occupies the entire surface of the latter with the exception of a peripheral portion 42 defining said compartment 41 as visible in FIG. figure 6 . This allows the portable object to operate using a larger electrical energy accumulator and therefore potentially more powerful or having a longer life. This module 10 also comprises at least one circuit 6 with at least one electrical contact zone 7, and a connection contact member 8 for providing an electrical connection between an accumulator 5 and a contact zone 7. This contact contact member 8 is elastically deformable so that when it undergoes strain deforming, its elastic capacity tends to bring it back to a geometry of rest. In a preferred but non-limiting version of the invention, this connecting contact member 8 is entirely elastic and is made in the form of a spring.

Selon l'invention, l'organe de contact de liaison se présente sous la forme d'une lame de forme 8. Cette lame de forme 8 comprend une partie centrale 81 rectiligne et présentant un profil plat comme visible à la figure 1. A chaque extrémité 82 de cette partie centrale 81 plate, au moins un bras 83 s'étend. On comprend que la lame de forme 8 comprend au moins un premier bras 83 et au moins un second bras 83.According to the invention, the binding contact member is in the form of a shape-shaped blade 8. This shape-shaped blade 8 comprises a part central 81 rectilinear and having a flat profile as visible in the figure 1 . At each end 82 of this flat central portion 81, at least one arm 83 extends. It is understood that the shaped blade 8 comprises at least a first arm 83 and at least a second arm 83.

Dans le cas où la lame de forme 8 comprend un premier bras 83 et un second bras 83, ladite lame de forme 8 est agencée pour que ledit premier bras 83 et ledit second bras 83 s'étendent dans le même plan. On comprend que le premier bras 83 et le second bras 83 s'étendent suivant le plan perpendiculaire au plan de la partie centrale 81.In the case where the shaped blade 8 comprises a first arm 83 and a second arm 83, said shaped blade 8 is arranged so that said first arm 83 and said second arm 83 extend in the same plane. It is understood that the first arm 83 and the second arm 83 extend in the plane perpendicular to the plane of the central portion 81.

Avantageusement, le premier bras 83 et le second bras 83 s'étendent de sorte à converger. Cette configuration des bras 83 permet d'obtenir une lame de forme 8 qui, naturellement, a une fonction de pince. En effet, lors du montage de l'accumulateur d'énergie électrique 5 dans la platine, ledit accumulateur 5 est, en premier lieu, placé dans son compartiment. Puis, l'organe de contact de liaison est fixé audit module 10 électronique. Pour cela, le module 10 électronique comprend deux encoches 11 agencées sur la face extérieure du module 10. Ces encoches sont réalisées pour être diamétralement opposées comme visible à la figure 5.Advantageously, the first arm 83 and the second arm 83 extend so as to converge. This configuration of the arms 83 provides a shape of blade 8 which, naturally, has a function of clamp. Indeed, during the mounting of the electrical energy accumulator 5 in the plate, said accumulator 5 is, in the first place, placed in its compartment. Then, the link contact member is attached to said electronic module. For this, the electronic module 10 comprises two notches 11 arranged on the outer face of the module 10. These notches are made to be diametrically opposed as visible in FIG. figure 5 .

Ainsi, lors de la fixation de l'organe de liaison de contact 8, le premier bras 83 et le second bras 83 sont écartés et s'insèrent dans les encoches prévues. La contrainte exercée sur les bras est ensuite relâchée de sorte que les premiers et seconds bras 83 tendent à reprendre leur position de repos, pinçant ainsi ledit module 10. Il suffit alors d'exercer une force sur la partie centrale de la lame de force 8 pour faire glisser cette dernière et la positionner dans sa position définitive. Cette position définitive se caractérise par le fait que la partie centrale 81 se trouve au contact de l'accumulateur d'énergie électrique 5. De même, le premier bras ou le second bras se trouve en contact d'une zone de contact 7 du circuit 6. Cette zone de contact 7 se présente sous la forme d'une métallisation pouvant être située sur la tranche du circuit 6. De ce fait, une conduction électrique est réalisée entre l'accumulateur d'énergie électrique et le circuit 6.Thus, during the fixing of the contact connecting member 8, the first arm 83 and the second arm 83 are spaced apart and fit into the slots provided. The stress exerted on the arms is then released so that the first and second arms 83 tend to return to their rest position, thereby pinching said module 10. It is then sufficient to exert a force on the central part of the force plate 8 to drag the latter and position it in its final position. This final position is characterized in that the central portion 81 is in contact with the electric energy accumulator 5. Similarly, the first arm or the second arm is in contact with a contact zone 7 of the circuit 6. This contact zone 7 is in the form of a metallization which can be located on the edge of the circuit 6. As a result, electrical conduction is achieved between the electric energy accumulator and the circuit 6.

De façon avantageuse, une zone de contact 7 est agencée au niveau de chaque encoche de sorte que chaque bras permette une conduction électrique. Une fois l'organe de contact de liaison 8 fixé, le module 10 électronique est placé dans le boîtier et le fond est fixé. Ce fond 3 peut être vissé ou chassé ou encliqueté à la carrure. De préférence, le module 10 électronique et le fond 3 sont agencés pour que ledit fond 3 et l'organe de contact de liaison 8 soient en contact.Advantageously, a contact zone 7 is arranged at each notch so that each arm allows electrical conduction. Once the connecting contact member 8 is fixed, the electronic module 10 is placed in the housing and the bottom is fixed. This bottom 3 can be screwed or driven or snapped to the middle part. Preferably, the electronic module 10 and the bottom 3 are arranged so that said bottom 3 and the contact contact member 8 are in contact.

Dans une première variante visible aux figures 2 et 6, la partie centrale 81 présente un profil non plat. Plus précisément, la partie centrale 81 présente un profil muni de plusieurs pointes 84 c'est-à-dire que la partie centrale 81 est en trois dimensions. Ces pointes 84 peuvent être des excroissances 86 agencées sur la partie centrale 81 et s'étendant de façon perpendiculaire au plan de la partie centrale. Ces pointes 84 peuvent être réalisées en déformant plastiquement ladite partie centrale 81 de sorte que celle-ci présente un profil non rectiligne c'est-à-dire comprenant des zones saillantes 87 de préférence s'étendant vers la pile. Par exemple, le profil peut être de forme de sinusoïde ou triangulaire.In a first variant visible to figures 2 and 6 , the central portion 81 has a non-flat profile. Specifically, the central portion 81 has a profile provided with several points 84 that is to say that the central portion 81 is in three dimensions. These points 84 may be protrusions 86 arranged on the central portion 81 and extending perpendicularly to the plane of the central portion. These tips 84 may be made by plastically deforming said central portion 81 so that it has a non-rectilinear profile that is to say including protruding areas 87 preferably extending towards the stack. For example, the profile may be sinusoidal or triangular.

Avantageusement, la partie centrale 81 est agencée pour avoir deux pointes 84. Ce pointes 84 permettent d'améliorer le contact électrique. Cette amélioration du contact électrique est due à la réalisation en trois dimensions de la partie centrale. Effectivement, avec cette variante, la partie centrale de la lame de forme 8 n'est en contact avec l'accumulateur d'énergie électrique 5 que par les pointes 84 dont elle est munie. Le fait que la partie centrale soit en trois dimensions entraîne, lorsque le module 10 électronique est placé dans le boitier 1 et que le fond 3 est fixé, l'apparition d'une contrainte. Cette contrainte est exercée sur l'organe de contact de liaison 8 qui transmet cette contrainte au module 10 électronique. Cette contrainte est le résultat du fait que le volume nécessaire pour englober la partie centrale en trois dimensions est plus important que si ladite partie centrale était plate. Dès lors que les dimensions intérieures du boîtier ne changent pas, une contrainte apparait.Advantageously, the central portion 81 is arranged to have two tips 84. These tips 84 can improve the electrical contact. This improvement of the electrical contact is due to the three-dimensional realization of the central part. Indeed, with this variant, the central portion of the shaped blade 8 is in contact with the electric energy accumulator 5 only by the tips 84 which it is provided. The fact that the central portion is in three dimensions causes, when the electronic module 10 is placed in the housing 1 and the bottom 3 is fixed, the appearance of a constraint. This constraint is exerted on the connecting contact member 8 which transmits this constraint to the electronic module. This constraint is the result of the fact that the volume needed to encompass the central part in three dimensions is more important than if said central portion was flat. Since the internal dimensions of the housing do not change, a constraint appears.

Cette contrainte permet premièrement de plaquer l'organe de contact de liaison 8 sur l'accumulateur d'énergie électrique 5. En conséquence, le contact électrique fait par ledit organe 8 entre le circuit 6 et l'accumulateur d'énergie électrique 5 est efficace et ne risque pas d'être interrompu.This constraint firstly makes it possible to press the contact contact member 8 on the electric energy accumulator 5. Consequently, the electrical contact made by said member 8 between the circuit 6 and the electric energy accumulator 5 is effective. and will not be interrupted.

Deuxièmement, cette contrainte permet d'immobiliser le module 10 électronique dans le boitier de l'objet portable. En effet, la contrainte exercée par le fond 3 sur l'organe de contact de liaison 8 est transmise sur la platine 4 qui est alors plaquée sur le module d'affichage. Le module 10 électronique est, par conséquent, maintenu immobile par l'ensemble formé de l'organe de contact de liaison 8 et du fond 3.Secondly, this constraint makes it possible to immobilize the electronic module in the box of the portable object. Indeed, the stress exerted by the bottom 3 on the contact contact member 8 is transmitted on the plate 4 which is then plated on the display module. The electronic module 10 is, therefore, held stationary by the assembly formed of the connecting contact member 8 and the bottom 3.

Dans une seconde variante visible à la figure 5, les extrémités libres 85 de chaque bras 83 sont courbées. Chaque extrémité libre 85 est courbée de sorte à présenter une courbure inverse à la courbure dudit bras 83. On comprend alors que cette extrémité 85 libre tend à diverger. Cette configuration des extrémités libres 85 des bras 83 permet de faciliter le montage dudit organe de contact de liaison 8. En effet, lorsque l'organe de contact de liaison 8 est fixé au module 10 électronique, les extrémités libres 85 courbés vont entrer en contact avec ledit module 10. La courbure divergente desdites extrémités entraîne un écartement desdites extrémités libres 85 et donc un écartement desdits bras 83. Cet écartement permet de fixer l'organe de contact de liaison 8 sans que l'utilisateur ne doive écarter les bras 83 lui-même. Cette opération se fait automatiquement lorsque l'utilisateur veut fixer ledit organe de contact de liaison 8.In a second variant visible to the figure 5 the free ends 85 of each arm 83 are curved. Each free end 85 is curved so as to have a curvature opposite to the curvature of said arm 83. It is then clear that this free end 85 tends to diverge. This configuration of the free ends 85 of the arms 83 facilitates the mounting of said contact contact member 8. Indeed, when the connecting contact member 8 is attached to the electronic module 10, the curved free ends 85 will come into contact with each other. with said module 10. The divergent curvature of said ends causes a spacing of said free ends 85 and therefore a spacing of said arms 83. This spacing makes it possible to fix the connecting contact member 8 without the user having to move the arms 83 apart. -even. This operation is done automatically when the user wants to fix said contact contact member 8.

Dans une troisième variante visible aux figures 3 et 4, l'organe de contact de liaison 8 est agencée pour que plusieurs bras 83 s'étendent depuis chaque extrémité 82 de la partie centrale 81. Préférentiellement, deux bras 83 s'étendent à partir de chaque extrémité 82 de la partie centrale 81. Dans ce cas, le module 10 électronique est agencé pour que les encoches situées sur la face extérieure du module 10 soient adaptées. On peut alors imaginer qu'un nombre d'encoches 11 identique au nombre de bras 83 est prévu ou que les encoches ont une taille permettant d'avoir plusieurs bras 83 par encoche 11.In a third variant visible to Figures 3 and 4 , the connecting contact member 8 is arranged so that several arms 83 extend from each end 82 of the central portion 81. Preferably, two arms 83 extend from each end 82 of the part In this case, the electronic module 10 is arranged so that the notches located on the outer face of the module 10 are adapted. One can then imagine that a number of notches 11 identical to the number of arms 83 is provided or that the notches have a size to have several arms 83 by notch 11.

Dans une première solution de cette variante visible à la figure 3, il est possible que les bras 83 s'étendant de sorte que, vue de dessus, chaque extrémité de la partie centrale a une forme similaire à un Y. Dans ce cas présent, les différents bras de la lame de forme sont tous convergents vers un seul point.In a first solution of this variant visible to the figure 3 it is possible that the arms 83 extending so that, seen from above, each end of the central portion has a shape similar to a Y. In this case, the different arms of the shape blade are all convergent towards a single point.

Dans une seconde solution visible à la figure 4, il est possible que chaque extrémité de la partie centrale 81 comprenne une partie perpendiculaire sorte que, vue de dessus, chaque extrémité de la partie centrale a une forme similaire à un T. Les bras 83 s'étendent depuis la partie perpendiculaire, de part et d'autre de la partie centrale. Dans ce cas présent, les différents bras de la lame de forme sont tous convergents vers un seul axe.In a second solution visible to the figure 4 it is possible that each end of the central portion 81 comprises a perpendicular portion so that, seen from above, each end of the central portion has a shape similar to a T. The arms 83 extend from the perpendicular portion, from and other of the central part. In this case, the different arms of the shape blade are all convergent towards a single axis.

Dans une autre variante, il est possible que l'accumulateur d'énergie électrique 5 n'occupe pas toute la surface de la platine 4, le compartiment pour ledit accumulateur étant dimensionnée en conséquence. Ladite platine est alors munie, à proximité de ce compartiment, d'orifices dans lesquels les encoches pour l'organe de contact de liaison sont réalisées.In another variant, it is possible that the electric energy accumulator 5 does not occupy the entire surface of the plate 4, the compartment for said accumulator being dimensioned accordingly. Said platen is then provided, near this compartment, orifices in which the notches for the connecting contact member are made.

On comprendra que diverses modifications et/ou améliorations et/ou combinaisons évidentes pour l'homme du métier peuvent être apportées aux différents modes de réalisation de l'invention exposée ci-dessus sans sortir du cadre de l'invention définie par les revendications annexées.It will be understood that various modifications and / or improvements and / or combinations obvious to those skilled in the art can be made to the various embodiments of the invention set out above without departing from the scope of the invention defined by the appended claims.
