The timepiece (10) has a case (12) formed by a middle part (20) closed in its top and bottom parts by a protective crystal (22) and a cover (26), respectively. The case has a partition (32) inserted between the middle part and the cover. The partition delimits top and bottom compartments at top and bottom parts of the case, respectively. The compartments, respectively contain electronic modules (14, 16) powered by a battery placed in a complementary housing in a bottom face (40) of the partition, where the modules, respectively comprise male connector and female connector (78). An independent claim is also included for a method for assembling a timepiece.
The invention relates to an electronic timepiece and a method for assembling it.
The invention more particularly relates to an electronic timepiece comprising a housing which contains at least a first and a second electronic module electrically connected to each other and powered by a battery, in which the housing is formed by a middle part which is closed, in its upper part, by a protective glass placed above a display device and, in its lower part, by a cover attached to the housing.
The document US 2005/0253047 describes and represents a timepiece constituted by a wristwatch comprising horological functions such as the display of the time and auxiliary functions to the time display constituted by pulse measuring functions of the wearer of the shows. The watch functions and the control of the display of the watch are processed by an electronic circuit arranged on an upper printed circuit board which is fixed in the middle part. The pulse measurement functions are processed by an electronic circuit arranged on a lower printed circuit board which is fixed on the bottom of the cover.
In this type of timepiece, the assembly of the various components that are superimposed in the case is relatively delicate. It requires the provision of fixing means inside the housing which are specially adapted to a given configuration of the timepiece. When it is desired to replace an electronic module with another electronic module, it is necessary to modify the structure of the housing which poses problems of cost and flexibility on the production line.
Furthermore, the fastening systems that are provided in the housing are not completely satisfactory and some components, such as the battery, are not maintained sufficiently.
It has also been found that, when the battery is changed, the electronic modules are very exposed which can lead to deteriorations having a negative effect on the reliability of the timepiece.
The invention aims in particular to remedy these disadvantages by proposing a simple and economical solution.
For this purpose, the invention proposes a timepiece of the type described above, characterized in that the housing comprises an attached partition which is fixed on the middle part and which delimits, in the upper part of the case, an upper compartment containing the first electronic module and, in the lower part of the case, a lower compartment containing the second electronic module, and in that the stack is arranged in a complementary dwelling in the underside of the partition.
Thanks to the invention, the two electronic modules are better isolated from each other and they are better held in the housing. In addition, the battery is easier to change and its arrangement in the housing of the partition facilitates its electrical connection to the electronic modules.
Preferably, the second electronic module is constituted by a printed circuit board carrying electronic components and fixed on the inner face of the cover. The cover has a plurality of pins which are integral with the cover and extend vertically through associated holes in the printed circuit board. The printed circuit board is held vertically on the cover by a deformation of the free end of each tenon. This arrangement of the second electronic module on the cover facilitates both the assembly of the second electronic module in the housing and the change of the battery.
Advantageously, the first electronic module comprises a male connector which extends downwards through an associated window of the partition, and the second electronic module comprises a complementary female connector which extends upwards for the electrical connection of the two modules. e. The use of these connectors makes it possible to simplify the electrical connection of the second electronic module with the first electronic module, in particular by limiting the number of contact flanges required for this connection. A more reliable electrical connection between the two modules is also obtained and the number of assembly operations is reduced.
Preferably, the first electronic module comprises a printed circuit board which is fixed on the middle part and the male connector is fixed rigidly on the lower face of the printed circuit board. The first electronic module comprises the display device, a clock circuit, and a control circuit of the display, and the second electronic module is dedicated to auxiliary functions with hourly functions such as pulse measurement functions. A perfectly modular construction is thus obtained and it is possible to modify the second electronic module without modifying the first electronic module.
According to an advantageous embodiment, the clock circuit and the control circuit of the display are arranged on the printed circuit board. The device The display plate and the printed circuit board are attached to a spacer interposed between the display device and the printed circuit board to form the first electronic module. The spacer is attached to the middle part. With this embodiment, the assembly operations are facilitated, and the first electronic module is an assembly easier to handle. In addition, by keeping a spacer with an identical external peripheral structure, it is possible to modify the printed circuit board and the display device, without this requiring modification of the structure of the upper housing compartment.
Preferably, the display device is removably attached to the spacer by resilient interlocking, which allows a faster and simpler change of the elements constituting the display device, while maintaining the same spacer.
Advantageously, the bottom of the battery housing has orifices giving access to the test and / or programming zones of the first electronic module. Thus, the first electronic module is protected by the partition and it is possible to intervene on the first electronic module without dismantling the partition.
The partition extends generally over the entire surface of the middle part in a plane parallel to the general plane of the cover. The cover is fixed on the partition which is interposed axially between the middle part and the cover. A "sandwich" assembly is obtained which is easy to industrialize and which allows a good protection of the first electronic module when a battery change is made or where it is desired to operate on the second electronic module.
The invention also proposes a method of assembling a timepiece according to one of the preceding characteristics, characterized in that it comprises the following successive steps:
insertion of the first electronic module into the middle part,
fixing the partition on the middle part,
mounting the battery in a housing arranged on the underside of the partition,
fixing the cover carrying the second electronic module on the housing.
Advantageously, there is provided a step of fixing the second electronic module on the cover which comprises the following successive steps:
positioning the printed circuit board of the second electronic module on the tenons of the cover,
heat-sealing applied on the free ends of the tenons so as to create localized deformations retaining the printed circuit board against the inner face of the cover.

The lower face 76 of the first printed circuit board 44 has electrical contact pads 79 which are arranged opposite the associated orifices 45 of the partition 32 and which constitute the test and / or programming zones of the first electronic module 14. These pads 79 allow for example to test the operation of the clock circuit 68 and the control circuit 70 of the display by means of an electronic test tool (not shown).
The second electrical module 16 is constituted here by a second printed circuit board 80 comprising electronic components dedicated to auxiliary functions at the time functions.
According to the exemplary embodiment shown in the figures, these auxiliary functions are constituted by functions related to the measurement of the pulse of the wearer of the watch. For this purpose, the second printed circuit board 80 comprises a pulse measuring unit 82 and a processing unit 84 of the pulse measurements which communicate the information to be displayed to the control circuit 70 of the display, in particular the value of the the wearer's pulse.
Of course, according to alternative embodiments (not shown) of the invention, the auxiliary functions may comprise different functions of the measurement of the pulse, for example altimeter, compass, satellite positioning, telephony functions, etc.
Advantageously, the second printed circuit board 80 is fixed on the inner face 86 of the cover 26. For this purpose, the cover 26 comprises several pins 88 which are made integrally with the cover 26 and which extend vertically through Associated holes 90 arranged in the second printed circuit board 80. The second printed circuit board 80 is held vertically against the cover 26 by a deformation of the free end of each post 88.
The female connector 78 is rigidly mounted on the upper face of the second printed circuit board 80 and extends vertically upwardly.
According to the preferred embodiment of the invention, the cover 26 is fixed on the lower face 40 of the partition 32, so that the partition 32 is interposed axially between the middle part 20 and the cover 26. The cover 26 is here fixed by means of four screws 91 which pass vertically through the partition 32 to screw into tapped holes 93 of the middle part 20.
The partition 32 extends generally over the entire surface of the caseband 20 in a horizontal plane, between the horns 28, 30, so that the partition 32 covers the entire lower face 76 of the first printed circuit board.
The partition 32 has a window 92 vis-à-vis the male connector 74 which allows the male connector 74 to fit into the female connector 78 through the partition 32. Advantageously, the free end 94 of the male connector 74 is substantially flush vertically with the edge 96 of the window 92, which ensures a good protection of the male connector 74, when the cover 26 and the second electronic module 16 are removed.
Advantageously, the electrical connection of the first electronic module 14 to the battery 18 is achieved by means of two metal contact flanges 98 which are arranged in the first compartment 34, between the first printed circuit board 44 and the upper face 100 of the partition. 32, and which extend partially on the bottom 43 of the battery housing 38.
The push buttons 31 are provided with metal contact blades 102 which are arranged in the first compartment 34 between the outer peripheral edge 104 of the first printed circuit board 44 and the inner axial wall 106 of the middle part 20.
It is noted that all the small independent electrical connection elements, such as the contact flanges 98 and the contact blades 102, are arranged in the upper compartment 34.
