Description

La présente invention concerne une montre comportant un boítier de montre dans lequel est disposé un premier module électrique, et un bracelet attaché audit boítier de montre et auquel sont associés un second module électrique et des moyens de connexion électrique assurant une connexion électrique entre ces premier et second modules électriques. Plus particulièrement, la présente invention concerne une telle montre comportant des moyens permettant d'introduire d'une manière étanche les moyens de connexion électrique à l'intérieur du boítier de la montre.The present invention relates to a watch comprising a case of watch in which is disposed a first electrical module, and a bracelet attached to said watch case and to which a second module is associated electrical and electrical connection means ensuring a connection electric between these first and second electric modules. More in particular, the present invention relates to such a watch comprising means for sealingly introducing the means of electrical connection inside the watch case.

Dans la présente description, on entendra par "moyens de connexion électrique" tout conducteur ou ensemble de conducteurs permettant d'assurer une liaison électrique entre deux modules électriques. De même, par "module électrique" on entendra tout dispositif destiné à fournir ou recevoir une alimentation électrique et, le cas échéant, à transmettre ou recevoir un signal électrique.In the present description, the term "connection means" will be understood. electric "any conductor or set of conductors allowing to provide an electrical connection between two electrical modules. Likewise, by "electrical module" means any device intended to supply or receive an electrical supply and, where appropriate, to transmit or receive a electrical signal.

Il est actuellement connu de disposer des modules électriques, tels des boutons de commande, des sources d'énergie électrique ou des circuits électroniques à l'extérieur du boítier d'une montre. Il est par exemple décrit dans le brevet suisse CH 343 323 une montre-bracelet munie d'un premier module électrique disposé à l'intérieur du boítier de la montre et d'un second module électrique comprenant une source d'énergie électrique associée au bracelet de la montre et destinée à alimenter le premier module électrique. Selon ce brevet, une connexion électrique isolée pénétrant directement à l'intérieur du boítier relie les premier et deuxième modules électriques.It is currently known to have electrical modules, such as control buttons, electrical power sources or circuits electronics on the outside of a watch case. It is for example described in Swiss patent CH 343 323 a wristwatch provided with a first electrical module placed inside the watch case and a second electrical module comprising a source of electrical energy associated with the watch strap and intended to power the first electrical module. According to this patent, an isolated electrical connection penetrating directly to the interior of the housing connects the first and second electrical modules.

Alternativement, afin d'assurer une connexion électrique adéquate entre des modules électriques situés respectivement à l'intérieur et à l'extérieur du boítier d'une montre, une solution couramment utilisée consiste à prévoir, sur les lignes de connexion entre les modules électriques, des contacts situés généralement au niveau de l'attache du bracelet au boítier de la montre. La connexion électrique est décomposée, dans ce cas, en une première portion, située à l'intérieur du boítier de la montre, et une seconde portion, située à l'extérieur du boítier de la montre. Cette solution est particulièrement adaptée à la réalisation de montres étanches car les moyens de connexion électrique ne pénètrent pas physiquement à l'intérieur du boítier.Alternatively, to ensure an adequate electrical connection between electrical modules located respectively inside and outside the a watch case, a commonly used solution is to provide, on connection lines between electrical modules, contacts located generally at the strap attachment to the watch case. The electrical connection is broken down, in this case, into a first portion, located inside the watch case, and a second portion, located at the outside of the watch case. This solution is particularly suitable the production of waterproof watches because the electrical connection means do not physically penetrate inside the case.

Un exemple d'un dispositif présentant ces caractéristiques est par exemple décrit dans le brevet européen EP 0186 804. Dans cet exemple, les contacts sont constitués d'un jeu de contacts conjugués séparables de sorte que le bracelet peut être facilement démonté et remonté sans qu'il y ait un risque de mauvais contact ou de détérioration de la qualité de l'étanchéité des contacts.An example of a device having these characteristics is by example described in European patent EP 0 186 804. In this example, the contacts consist of a set of separable conjugate contacts so that the bracelet can be easily disassembled and reassembled without there being a risk of poor contact or deterioration in the quality of the seal contacts.

On constatera toutefois que la réalisation d'un tel dispositif devient particulièrement problématique lorsque le nombre de lignes de connexion, et par là même le nombre de contacts, devient important. En effet, la taille et les dimensions des différents contacts limite le nombre de lignes de connexion qu'il est possible de connecter au boítier de la montre.However, it will be noted that the production of such a device becomes particularly problematic when the number of connection lines, and thereby the number of contacts becomes important. Indeed, the size and dimensions of the different contacts limit the number of connection lines that it is possible to connect to the watch case.

Comme on l'a déjà mentionné, il est alternativement possible d'introduire directement les moyens de connexion électrique à l'intérieur du boítier de la montre sans faire usage de contacts intermédiaires. A cet effet, les moyens de connexion électrique peuvent être introduits au travers d'un orifice ménagé dans le boítier de la montre comme cela est par exemple décrit dans le brevet suisse CH 343 323 déjà cité. L'inconvénient de la solution décrite dans ce brevet réside dans le fait que l'assemblage ainsi réalisé est difficilement démontable. En particulier, afin d'assurer l'étanchéité du boítier de la montre, il est nécessaire de prévoir autour des moyens de connexion électrique une enveloppe de protection rendant hermétique l'orifice ménagé dans le boítier de la montre. Cette enveloppe est ainsi typiquement chassée dans l'orifice ménagé dans le boítier de la montre. Il s'en suit que le démontage du bracelet et des moyens de connexion électrique est rendu complexe et difficile. On peut par ailleurs constater qu'un autre inconvénient de la construction présentée dans ce brevet suisse réside dans le fait que l'enveloppe de protection entourant les moyens de connexion électrique est directement soumise à des efforts mécaniques qui peuvent engendrer une détérioration de l'étanchéité du boítier au niveau de l'orifice ou éventuellement conduire à une rupture des moyens de connexion électrique.As already mentioned, it is alternatively possible to directly introduce the electrical connection means inside the watch case without making use of intermediate contacts. To this end, the electrical connection means can be introduced through a hole in the watch case as it is for example described in the Swiss patent CH 343 323 already cited. The downside of the solution described in this patent lies in the fact that the assembly thus made is difficult to dismantle. In particular, in order to ensure watertightness of the watch case, it is necessary to provide around the means of electrical connection a protective envelope making the orifice airtight housed in the watch case. This envelope is thus typically driven into the hole in the watch case. It follows that the disassembly of the bracelet and the electrical connection means is returned complex and difficult. We can also see that another drawback of the construction presented in this Swiss patent lies in the fact that the protective envelope surrounding the electrical connection means is directly subjected to mechanical forces which can generate a deterioration of the tightness of the case at the orifice or possibly lead to a break in the electrical connection means.

Un but de la présente invention est ainsi de proposer une montre du type susmentionné dans laquelle les moyens de connexion électrique peuvent être introduits directement à l'intérieur du boítier de la montre et qui ne présente pas les inconvénients qui viennent d'être mentionnés. An object of the present invention is thus to propose a watch of the aforementioned type in which the electrical connection means can be introduced directly inside the watch case and which does not not have the disadvantages which have just been mentioned.

En particulier, un but de la présente invention est de permettre un montage et démontage aisé du bracelet et des moyens de connexion électrique intégrés dans le bracelet tout en assurant une étanchéité optimale de l'ensemble.In particular, an object of the present invention is to allow a easy assembly and disassembly of the bracelet and connection means electric integrated in the bracelet while ensuring optimal sealing from the whole.

A cet effet, la présente invention a pour objet une montre comportant un boítier de montre dans lequel est disposé un premier module électrique, et un bracelet attaché audit boítier de montre et auquel sont associés un second module électrique et des moyens de connexion électrique assurant une connexion électrique entre lesdits premier et second modules électriques, caractérisée en ce que celle-ci comporte des moyens d'introduction permettant d'introduire de manière étanche lesdits moyens de connexion électrique à l'intérieur du boítier de montre, ces moyens d'introduction étant disposés dans un orifice d'introduction ménagé dans ledit boítier de montre et retenus au moyen d'un axe, cette montre comportant en outre des moyens d'étanchéité assurant une étanchéité dudit orifice d'introduction lorsque les moyens d'introduction y sont disposés.To this end, the subject of the present invention is a watch comprising a watch case in which a first electrical module is disposed, and a bracelet attached to said watch case and to which is associated a second electrical module and electrical connection means ensuring a electrical connection between said first and second electrical modules, characterized in that it comprises means of introduction for sealingly introducing said connection means inside the watch case, these means of introduction being arranged in an introduction orifice formed in said watch case and retained by means of an axis, this watch further comprising means sealing ensuring sealing of said introduction orifice when the means of introduction are arranged there.

Des modes de réalisation avantageux de la présente invention font l'objet des revendications dépendantes.Advantageous embodiments of the present invention provide the subject of the dependent claims.

Grâce à ces caractéristiques, les moyens de connexions électriques peuvent pénétrer directement à l'intérieur du boítier de la montre. Les moyens d'introduction sont maintenus en position par l'axe de sorte que le montage et démontage de l'ensemble est facilité. En effet, les moyens d'introduction n'étant en particulier pas chassés dans l'orifice d'introduction ménagé dans le boítier de montre, le montage, respectivement le démontage de ceux-ci est aisément effectué par l'introduction, respectivement le retrait de l'axe. L'axe retenant les moyens d'introduction peut en outre avantageusement former un axe d'articulation du bracelet.Thanks to these characteristics, the means of electrical connections can penetrate directly inside the watch case. Ways are kept in position by the axis so that the mounting and disassembly of the assembly is facilitated. Indeed, the means of introduction in particular not being driven into the introduction opening formed in the watch case, mounting, respectively disassembly of these is easily carried out by the introduction, respectively the withdrawal of the axis. The axis retaining the introduction means can also advantageously form a hinge axis of the bracelet.

Les moyens d'étanchéité assurent par ailleurs une étanchéité optimale de la montre au niveau de l'orifice d'introduction.The sealing means also ensure optimum sealing of the watch at the insertion opening.

Cette solution permet en outre de s'affranchir totalement de la structure particulière des moyens de connexion électrique. En particulier, le nombre de lignes de connexion ne constitue plus une limitation car les moyens d'introduction sont indépendants des moyens de connexion électrique utilisés.This solution also makes it possible to completely overcome the particular structure of the electrical connection means. In particular, the number of connection lines is no longer a limitation because the means are independent of the electrical connection means used.

On constatera en outre que la solution selon la présente invention permet également de réduire les coûts de fabrication de la montre par rapport aux solutions de l'art antérieur employant des contacts intermédiaires, car le nombre de pièces nécessaires pour permettre l'introduction des moyens de connexion électrique est sensiblement limité.It will also be noted that the solution according to the present invention also reduces the manufacturing costs of the watch by compared to prior art solutions employing contacts because the number of pieces needed to allow the introduction of the electrical connection means is substantially limited.

D'autres caractéristiques et avantages de l'invention apparaítront plus clairement à la lecture de la description détaillée qui suit, faite en référence aux dessins annexés donnés à titre d'exemples non limitatifs et dans lesquels :

Other characteristics and advantages of the invention will appear more clearly on reading the detailed description which follows, given with reference to the appended drawings given by way of nonlimiting examples and in which:
  • Figure 1 is an overview of a watch according to the present invention;
  • Figure 2 is an enlarged sectional view of a portion of the watch constituting a first embodiment of the present invention;

La figure 1 illustre une montre selon la présente invention. Cette montre comporte ainsi un boítier de montre 1 et un bracelet 2 attaché au boítier de montre 1, de manière non limitative, par des charnières 11 et 12. Le boítier de montre 1 comprend par ailleurs un fond 1a et une carrure 1b sur laquelle est montée une glace 10.Figure 1 illustrates a watch according to the present invention. This watch thus comprises a watch case 1 and a strap 2 attached to the case shows 1, without limitation, by hinges 11 and 12. The housing watch 1 also includes a base 1a and a middle part 1b on which rose a window 10.

Le boítier de montre 1 renferme typiquement un mouvement horloger ou alternativement un circuit électronique horloger permettant la formation et l'affichage d'une information horaire. Dans la présente description, on a désigné de manière générale par les termes "premier module électrique" (référence 5 dans les figures), l'ensemble, ou tout du moins une partie substantielle des moyens électriques et/ou électroniques disposés à l'intérieur du boítier de montre 1. Ces moyens électriques et/ou électroniques peuvent être très divers et variés selon qu'il s'agisse d'une montre de type électromécanique ou électronique. Cette montre peut par ailleurs présenter des complications supplémentaires (par ex. module radio fréquence, module GPS, etc.). Dans le cadre de la présente invention, on comprendra donc que par "premier module électrique" on désignera tout dispositif électrique/électronique disposé à l'intérieur du boítier de montre et destiné à collaborer avec un dispositif électrique disposé à l'extérieur du boítier de montre. Watch case 1 typically contains a watch movement or alternatively a watchmaking electronic circuit allowing training and the display of time information. In the present description, we have generally referred to as "first electrical module" (reference 5 in the figures), the whole, or at least a part substantial electrical and / or electronic means arranged inside of the watch case 1. These electrical and / or electronic means can be very diverse and varied depending on whether it is a type watch electromechanical or electronic. This watch may also have additional complications (e.g. radio frequency module, module GPS, etc.). In the context of the present invention, it will therefore be understood that "first electrical module" means any device electric / electronic placed inside the watch case and intended for collaborate with an electrical device located outside the housing watch.

De manière similaire, dans le cadre de la présente invention, les termes "second module électrique" (référence 6 dans les figures) désignent de manière générale un dispositif électrique/électronique disposé à l'extérieur du boítier de montre et destiné à collaborer avec le premier module électrique 5 de manière à fournir ou recevoir une alimentation électrique et, le cas échéant, à transmettre ou recevoir un signal électrique. Typiquement, ce second module électrique 6 peut comprendre une source d'énergie électrique (batterie, accumulateur, etc.), des moyens d'interface avec un utilisateur (boutons de commande, clavier, etc.), ou tout autre circuit électronique destiné à collaborer avec le premier module électrique 5 (mémoires, carte à puce, etc.). Ce second module électrique peut en outre être associé au bracelet de la montre.Similarly, in the context of the present invention, the terms "second electrical module" (reference 6 in the figures) denotes generally an electrical / electronic device placed outside the watch case and intended to collaborate with the first electrical module 5 so as to provide or receive electrical power and, where appropriate, to transmit or receive an electrical signal. Typically, this second electrical module 6 may include a source of electrical energy (battery, accumulator, etc.), means of interfacing with a user (control buttons, keyboard, etc.), or any other electronic circuit intended to collaborate with the first electrical module 5 (memories, card to chip, etc.). This second electrical module can also be associated with the watch strap.

Afin d'assurer une connexion électrique entre ces premier et second modules électriques 5 et 6, la montre faisant l'objet de la présente invention comprend par ailleurs des moyens de connexion électrique 3, associés dans cet exemple au bracelet 2 de la montre. Dans le cadre de la présente invention, ces moyens de connexion électrique 3 pénètrent directement à l'intérieur du boítier de montre 1 afin d'être connectés au premier module électrique 5.In order to ensure an electrical connection between these first and second electrical modules 5 and 6, the watch forming the subject of the present invention further includes electrical connection means 3, associated in this example on strap 2 of the watch. In the context of this invention, these electrical connection means 3 penetrate directly to inside the watch case 1 in order to be connected to the first module electric 5.

A cet effet, tel que cela est illustré dans les figures 2 et 3 présentant un premier mode de réalisation de la présente invention, un orifice d'introduction 17 est ainsi ménagé dans la carrure 1b du boítier de montre 1 au niveau de l'attache du bracelet 2, soit, dans cet exemple, au niveau de la charnière 11.To this end, as illustrated in Figures 2 and 3 showing a first embodiment of the present invention, an orifice introduction 17 is thus formed in the middle part 1b of the watch case 1 at the strap 2 attachment, or, in this example, at the hinge 11.

Dans les modes de réalisation présentés ici, les moyens de connexion électrique 3 sont formés d'un substrat souple supportant une pluralité de pistes conductrices. On notera toutefois que le type et la structure de ces moyens de connexion électrique 3 ne sont pas déterminants. En effet, il importe peu que ces moyens de connexion électrique 3 soient réalisés sous la forme d'un ensemble de pistes conductrices formées sur un substrat diélectrique souple, comme cela est le cas dans cet exemple, ou, alternativement, sous la forme d'un ensemble de conducteurs indépendants. On comprendra donc que différents types de moyens de connexion électrique peuvent être utilisés, ce qui constitue un avantage substantiel vis-à-vis des dispositifs connus décrits en préambule, tel celui décrit dans le brevet européen EP 0 186 804 déjà cité. In the embodiments presented here, the connection means electrical 3 are formed of a flexible substrate supporting a plurality of conductive tracks. It should be noted, however, that the type and structure of these electrical connection means 3 are not decisive. Indeed, it it does not matter that these electrical connection means 3 are made under the form of a set of conductive tracks formed on a substrate flexible dielectric, as is the case in this example, or, alternatively, in the form of a set of independent conductors. It will therefore be understood that different types of electrical connection means can be used, which is a substantial advantage over known devices described in the preamble, such as that described in the patent European EP 0 186 804 already cited.

Selon le premier mode de réalisation de la présente invention illustré aux figures 2 et 3, afin de permettre l'introduction des moyens de connexion électrique 3 à l'intérieur du boítier de montre 1 tout en assurant une étanchéité de ce dernier, la montre comporte des moyens d'introduction formés d'un élément d'introduction 4 disposé dans l'orifice d'introduction 17 ménagé dans le boítier de montre 1. Cet élément d'introduction 4 présente dans cet exemple une forme sensiblement tubulaire permettant le passage des moyens de connexion électrique 3.According to the first embodiment of the present invention illustrated in Figures 2 and 3, to allow the introduction of connection means electric 3 inside the watch case 1 while ensuring waterproofing of the latter, the watch includes means of introduction formed by an introduction element 4 disposed in the introduction hole 17 formed in the watch case 1. This introductory element 4 has in this example a substantially tubular shape allowing passage electrical connection means 3.

Cet élément d'introduction 4 est retenu dans sa position au moyen d'un axe 21 qui forme avantageusement dans cet exemple un axe d'articulation de la charnière 11. Cette solution permet de disposer l'élément d'introduction 4 sans devoir chasser celui-ci dans l'orifice d'introduction 17. Il s'en suit que le montage et le démontage du bracelet 2 et des moyens de connexion électrique 3 ne présente pas de difficultés majeures, la seule contrainte résidant dans la liaison de moyens de connexion électrique 3 au premier module électrique 5 disposé à l'intérieur du boítier de montre 1.This introducer 4 is retained in its position by means of a axis 21 which advantageously forms in this example an articulation axis of the hinge 11. This solution makes it possible to arrange the insertion element 4 without having to drive it into the introduction hole 17. It follows that the assembly and disassembly of bracelet 2 and connection means electric 3 does not present any major difficulties, the only constraint residing in the connection of electrical connection means 3 to the first electrical module 5 arranged inside the watch case 1.

Comme cela ressort de la figure 3, la charnière 11 comprend, dans cet exemple non limitatif, deux portions extérieures 16a et deux portions intermédiaires 16b venues de matière avec la carrure 1b du boítier de montre 1. La charnière 11 comporte également deux éléments 28 venus de matière avec le bracelet 2, chaque élément 28 étant respectivement engagé dans un espace 18 subsistant entre une portion extérieure 16a et une portion intermédiaire 16b voisines. Dans cet exemple, l'orifice d'introduction 17 dans lequel est disposé l'élément d'introduction 4 est ménagé entre les deux portions intermédiaires 16b de la charnière 11.As can be seen from FIG. 3, the hinge 11 comprises, in this nonlimiting example, two outer portions 16a and two portions intermediaries 16b made of material with the middle part 1b of the watch case 1. The hinge 11 also comprises two elements 28 made of material with bracelet 2, each element 28 being respectively engaged in a space 18 remaining between an outer portion 16a and a portion neighboring intermediate 16b. In this example, the insertion hole 17 in which is arranged the introduction element 4 is formed between the two intermediate portions 16b of the hinge 11.

Chaque portion 16a et 16b, ainsi que chaque élément 28 de la charnière est percé d'un trou dans lequel est inséré l'axe d'articulation 21 de la charnière 11. Dans cet exemple, l'élément d'introduction 4 est, de manière similaire, percé d'un trou 41 permettant le passage de l'axe d'articulation 21. Alternativement, afin de retenir l'élément d'introduction 4, il est envisageable d'utiliser des premier et second axes d'articulation venant de part et d'autre de l'élément d'introduction 4 de manière à s'affranchir de la nécessité de ménager un trou au travers de celui-ci.Each portion 16a and 16b, as well as each element 28 of the hinge is drilled with a hole in which is inserted the hinge pin 21 of the hinge 11. In this example, the introduction element 4 is, so similar, drilled with a hole 41 allowing the passage of the hinge pin 21. Alternatively, in order to retain the insertion element 4, it is conceivable to use first and second axes of articulation coming from both sides of the introduction element 4 so as to overcome the need for make a hole through it.

On mentionnera en outre que le bracelet de la montre peut alternativement être attaché au boítier de la montre au moyen d'une barrette fixée entre des cornes ménagées sur le boítier de la montre, cette barrette pouvant être utilisé pour assurer le maintien de l'élément d'introduction. It should also be noted that the watch strap can alternatively be attached to the watch case by means of a bar fixed between horns formed on the watch case, this bar can be used to maintain the introducer.

Afin d'assurer une étanchéité adéquate du boítier de montre 1 au niveau de l'orifice d'introduction 17, la montre selon la présente invention comporte en outre des moyens d'étanchéité 7 assurant une étanchéité de l'orifice d'introduction 17. Dans le mode de réalisation illustré aux figures 1 à 3, ces moyens d'étanchéité comportent un joint annulaire 71 disposé dans un canal 42 ménagé sur une partie extérieure de l'élément d'introduction 4.To ensure adequate sealing of the watch case 1 to level of the introduction orifice 17, the watch according to the present invention further comprises sealing means 7 ensuring a sealing of the introduction orifice 17. In the embodiment illustrated in FIGS. 1 to 3, these sealing means comprise an annular seal 71 disposed in a channel 42 formed on an outer part of the insertion element 4.

Selon ce premier mode de réalisation de la présente invention, la montre comporte en outre un joint tampon 72 disposé à l'intérieur de l'élément d'introduction 4. Ce joint tampon 72 peut-être réalisé par le dépôt d'un joint en silicone après le montage des moyens de connexion électrique 3. Alternativement, ce joint tampon 72 peut être surmoulé autour des moyens de connexion électrique 3.According to this first embodiment of the present invention, the watch further comprises a buffer gasket 72 disposed inside the insertion element 4. This buffer joint 72 can be produced by the deposit a silicone gasket after mounting the electrical connection means 3. Alternatively, this buffer joint 72 can be molded around the means electrical connection 3.

Selon ce second mode de réalisation, la montre comporte des moyens d'introduction qui diffèrent légèrement des moyens utilisés dans le précédant mode de réalisation. Les moyens d'introduction sont formés dans cet exemple d'un élément d'introduction 8 comportant, sur sa partie extérieure, au moins un bourrelet de matière 81 formant les moyens d'étanchéité 7 de la montre. Lorsque l'élément d'introduction 8 est inséré dans l'orifice d'introduction 17, le bourrelet de matière 81 empêche toute infiltration de liquide. Alternativement, le bourrelet de matière peut être réalisé sur une partie intérieure de l'orifice d'introduction 17.According to this second embodiment, the watch includes means of introduction which differ slightly from the means used in the previous embodiment. The introduction means are formed in this example an introduction element 8 comprising, on its external part, at least a bead of material 81 forming the sealing means 7 of the watch. When the introduction element 8 is inserted into the introduction hole 17, the bead of material 81 prevents any infiltration of liquid. Alternately, the bead of material can be produced on an interior part of the orifice introduction 17.

La figure 5 présente une vue en coupe d'une portion d'une montre constituant un troisième mode de réalisation de la présente invention. Les éléments communs aux modes de réalisation déjà présentés ne seront pas décrits à nouveau et sont désignés par les mêmes références numériques.Figure 5 shows a sectional view of a portion of a watch constituting a third embodiment of the present invention.

Selon ce troisième mode de réalisation, l'orifice d'introduction 17 présente, dans sa partie terminale débouchant dans le boítier de montre 1, une portion de diamètre réduit 17a contre laquelle viennent buter les moyens d'introduction formés dans cet exemple d'un élément d'introduction indiqué par la référence numérique 9. Cet élément d'introduction 9 présente ici une face frontale 9a destiné à comprimer un joint 73 contre la portion 17a lorsque cet élément d'introduction 9 est inséré et monté dans l'orifice d'introduction 17. Le joint 73 destiné à être comprimé peut être réalisé par le surmoulage d'un joint autour des moyens de connexion électrique 3 ou alternativement par le dépôt d'un joint en silicone.According to this third embodiment, the introduction orifice 17 present, in its terminal part opening into the watch case 1, a reduced diameter portion 17a against which the means abut of introduction formed in this example of an indicated introductory element by the reference numeral 9. This introductory element 9 here presents a front face 9a intended to compress a joint 73 against the portion 17a when this introducer 9 is inserted and mounted in the hole introduction 17. The seal 73 intended to be compressed can be produced by the overmolding of a seal around the electrical connection means 3 or alternatively by depositing a silicone seal.

La figure 6 présente une vue en coupe d'une portion d'une montre constituant un quatrième mode de réalisation de la présente invention. Les éléments communs aux modes de réalisation déjà présentés ne seront pas décrits à nouveau et sont désignés par les mêmes références numériques.Figure 6 shows a sectional view of a portion of a watch constituting a fourth embodiment of the present invention. The elements common to the embodiments already presented will not be described again and are designated by the same reference numerals.

Selon ce quatrième mode de réalisation, les moyens d'introduction indiqués dans cet exemple par la référence numérique 44, sont formés d'un élément d'introduction venant de matière avec le bracelet 2 et font ainsi avantageusement partie intégrante de ce dernier. Selon ce mode de réalisation, il est ainsi éventuellement possible de s'affranchir de la présence d'un joint tampon disposé à l'intérieur des moyens d'introduction 44, l'étanchéité pouvant être assurée directement au niveau du bracelet. Le cas échéant, un tel joint tampon peut être réalisé depuis l'intérieur du boítier de montre 1 lors du montage du bracelet et des moyens de connexion électrique.According to this fourth embodiment, the introduction means indicated in this example by the reference numeral 44, are formed by a introductory element coming from material with the bracelet 2 and do so advantageously an integral part of the latter. According to this mode of realization, it is thus possibly possible to get rid of the presence a buffer seal disposed inside the introduction means 44, the watertightness can be ensured directly at the strap. The case if necessary, such a buffer seal can be produced from inside the housing of shows 1 when mounting the bracelet and the electrical connection means.

Afin d'assurer l'étanchéité du boítier de montre 1 au niveau de l'orifice d'introduction 17, la montre comporte dans cet exemple, de manière analogue au premier mode de réalisation déjà présenté, un joint annulaire 71 disposé dans un canal 42 ménagé sur une partie extérieur de l'élément d'introduction 44. On notera toutefois que les moyens d'étanchéité présentés en relation avec les second et troisième modes de réalisation, à savoir la réalisation d'au moins un bourrelet de matière sur l'élément d'introduction ou d'un joint compressé contre une portion de l'orifice d'introduction, sont également applicables par analogie.To ensure the tightness of the watch case 1 at the orifice introduction 17, the watch comprises in this example, so analogous to the first embodiment already presented, an annular seal 71 disposed in a channel 42 formed on an external part of the element 44. Note however that the sealing means presented in relation to the second and third embodiments, namely the production of at least one bead of material on the insertion element or of a seal compressed against a portion of the introduction orifice, are also applicable by analogy.

Selon la présente invention, on notera finalement que les moyens d'introduction des moyens de connexion électrique peuvent avantageusement être réalisés en matière plastique.
