Definitions

  • the present invention relates to a watch comprising a dial. More specifically, the present invention relates to an electromechanical or digital watch comprising at least one electronic device arranged in the watch case.
  • electromechanical watch means a watch comprising at least one indicator of a time value or of a magnitude unrelated to time driven by an electric motor.
  • digital watch means a watch comprising at least one digital display device of a time magnitude or of a magnitude unrelated to time.
  • dial means an indicator organ which carries various indications, hourly or not related to time.
  • Electromechanical watches as well as digital watches, comprise a plurality of discrete or integrated electronic components necessary for their operation. These electronic components are typically mounted on printed circuit boards housed in the watch cases, below the surface of the dial and at a distance therefrom.
  • the present invention aims to remedy these disadvantages as well as others by providing a dial for a watch electromechanical or digital enabling advantageously to overcome, at least partially, printed circuit boards.
  • the present invention relates to an electromechanical or digital watch, the watch comprising a caseband which delimits with an ice a watch case, the ice comprising an upper face oriented on the side of a user, and a lower face oriented on the side. of the watch case, the watch also comprising a dial made of a non-electrically conductive material, the dial comprising a lower surface and an upper surface situated on the side of an observer, the watch being characterized in that tracks electrically conductive connectors for connecting one or more electronic components are structured on at least one of the lower or upper surfaces of the dial.
  • the dial is made of glass, a plastic material or even a ceramic material.
  • the present invention provides a watch whose dial is made of a non-electrically conductive material, so that at least one of the lower and upper surfaces of this dial can be used for structuring electrically conductive tracks for the electrical connection of at least one discrete or integrated electronic component. It is thus possible to overcome or, at least, to limit the surface of the printed circuit boards necessary for mounting the electronic components of the watch, which makes it possible to limit the costs in terms of the number of printed circuit boards used. and manufacturing time, as well as reduce the clutter of the watch movement housed in the watch case.
  • the present invention proceeds from the general inventive idea of using one and / or the other of the upper and lower surfaces of a watch dial made of a non-conductive material of electricity to structure conductive tracks allowing to connect discrete or integrated electronic components necessary for the operation of the watch. In this way, it is possible to eliminate, or at least limit the surface of the printed circuit boards, which limits the time and manufacturing costs, and reduce the size of the watch movement housed in the circuit. watch box.
  • the present invention will be described in connection with a timepiece comprising an ice on the lower surface of which are structured tactile keys. It goes without saying that this example is given for purely illustrative and not limiting purposes only, and that a watch face according to the invention can be used with any type of electronic device integrated in a watch case.
  • the figure 1 attached to the present patent application is a sectional view of a watch equipped with a dial according to the invention.
  • this watch comprises a middle part 2 which delimits with a mirror 4 a watch box 6.
  • the window 4 comprises an upper face 8 directed towards the side of a user of the watch 1, and a lower face 10 directed towards the side of the watch case 6.
  • an electronic device On the lower face 10 of the window 4 is arranged an electronic device.
  • the electronic device can be of any type. he may be a digital display device, for example liquid crystal, or (see single figure) first conductive tracks 12 made of a transparent electrically conductive material such as tin oxide indium, better known under the name Anglo-Saxon Indium-Tin Oxide or ITO. These first conductive tracks 12 have the function of materializing on the surface of the glass 4 tactile keys sensitive to variations in capacity and allowing the user, by applying a finger 14, to introduce instructions into an electronic circuit 16 touch key management.
  • This electronic management circuit 16 is mounted on a lower surface of a dial 18 according to the invention housed in the watch case 6, under and away from the first conductive tracks 12, and supported by a flange 20.
  • the assembly is completed by an electronic circuit 22 which controls the execution of a watchmaking or other function according to the instructions provided by the electronic management circuit 16.
  • the first conductive tracks 12 define electrical contact pads 24 that it is necessary to transfer from the lower face 10 of the glass 4 to the dial 18.
  • the dial 18 comprises for this purpose second conductive tracks 26 which correspond to the electrical contact pads 24 and which are connected to the electronic management circuit 16 and the electronic control circuit 22.
  • the second conductive tracks 26 are structured only on a lower face 28 of the dial 18. It goes without saying, however, that conductive tracks may also be structured on the upper face of the dial 18, in particular if these conductive tracks are transparent.

Subsequently, the second conductive tracks 26 are structured by an electroplating process. According to a variant, it is also possible to structure the second conductive tracks 26 on the surface of the dial 18 by printing an electrically conductive ink. It is also conceivable to make the dial 18 by a method of bi-injection of a plastic material and a conductive material followed by an electroplating step.
  • the conductive tracks structured on the dial according to the invention do not necessarily serve to connect tactile keys formed on the underside of a watch crystal to electronic management and control circuits fixed on the dial. . It is thus quite possible to structure on one and / or the other of the lower and upper surfaces of the dial conductive tracks for interconnecting for example electronic circuits for managing and controlling a component housed in the volume of the watch case as an electric motor step-by-step.
  • the figure 2 is a sectional view of a watch equipped with a dial according to an alternative embodiment of the invention.
