Definitions

  • the present invention relates to a portable bracelet object provided with electrical connection means through the housing.
  • the portable object comprises the features defined in independent claim 1.
  • the present invention also relates to a method of mounting including the electrical contact flange for a portable bracelet.
  • the term "electrical connection means" any conductor or set of conductors for providing an electrical connection between at least one contact terminal of an electronic circuit and at least one conductive track disposed in the bracelet.
  • This conductive track can be an antenna for transmitting and receiving signals or electrically connect an electrical component contained in the bracelet and the electronic circuit in the housing.
  • the portable object is made in the form of a portable electronic instrument in the form of a wristwatch.
  • This wristwatch may comprise means for receiving or transmitting radiofrequency type signals if the conductive track of the bracelet defines an antenna.
  • the electronic circuit for processing electrical signals makes it possible to manage the transmission or reception of information signals by the antenna.
  • the European patent No 0 631 341 describes an electronic instrument of the wristwatch type comprising an antenna housed in the bracelet and connected to an electronic circuit for processing the signals received by the antenna.
  • the electronic processing circuit is disposed within the instrument housing on a printed circuit board.
  • Connection pads are provided on a region peripheral of the printed circuit board to enable the establishment of an electrical connection between the electronic signal processing circuit and the connection terminals of the antenna which passes through a side wall of the housing.
  • fixing screws pass through apertures adapted from the terminals of the antenna so as to be screwed directly into the printed circuit board at the connection pads to ensure the electrical connection.
  • a spring blade type connector fixed to the printed circuit board for each terminal of the antenna, on which an electrical conductor connected to one of the terminals is supported. of the antenna.
  • Each conductor connected to an antenna terminal must pass through the side wall in order to rest on the spring blade to establish the electrical contact.
  • An annular seal is provided around said conductor in the passageway through the sidewall,
  • a disadvantage of the electronic instrument presented in European Patent No 0 631 341 is that part of the antenna must pass through a side wall of the housing so that it can be directly connected to the printed circuit board. Therefore, the seal at the side wall of the housing, even with the annular seal, is not guaranteed in time and according to the handling of the bracelet.
  • Another disadvantage of the first embodiment with fixing screws is that a subsequent replacement of the antenna in the event of a problem makes it essential to completely dismantle the instrument casing before being able to access the fixing screws, which can make this operation tedious.
  • the bracelet comprises an antenna which is connected to an electronic circuit in the housing via at least one contact flange passing in isolation through the side wall of the housing.
  • the contact flange is sealingly held through the side wall by insulating joints.
  • these insulating joints are not intended to permanently fix the contact flange through the side wall of the portable object, which does not guarantee a good seal at the side wall of the housing.
  • the main purpose of the invention is thus to overcome the drawbacks of the prior art by providing a portable bracelet object provided with electrical connection means passing through a side wall of the housing in a sealed manner without being disturbed in particular by various manipulations of the bracelet.
  • the invention relates to a portable object cited above which comprises the features defined in the independent claim 1.
  • An advantage of the portable bracelet object according to the invention lies in the fact that the intermediate portion of each flange is fixed by a sealing material introduced into a cavity formed between a first and a second portion of the side wall.
  • the sealing material completely surrounds in the cavity the flange which may be a metal blade, and closes the passage openings of said flange.
  • This sealing material is different from the insulating material used for the side wall. In this way, the sealing of said flange through the side wall is sealed, since the properties of the sealing material do not change over time in the same way as the side wall.
  • the sealing material is a polymerizable adhesive or silicone which solidifies at room temperature for a period of time which can be of the order of 24 hours.
  • the first part of the metal flange inside the housing is advantageously in the form of S to form a compression spring.
  • a printed circuit board carrying the electronic circuit compresses the first portion of the flange at a contact pad of said plate. .
  • a better electrical contact is thus ensured because the first portion of the compressed flange exerts a contact force against the contact pad of said plate.
  • the second portion of the blade-shaped metal flange is disposed above an upper surface of a mounting flange of the wristband in the rest position, i.e. prior to the electrical connection to the conductive track of the bracelet.
  • This second part comprises a hole adapted to the passage of a metal connection screw which is screwed into a hole in the rim.
  • the end of the conductive track also comprises a hole adapted to the passage of a metal screw. In this way, the end of the conductive track and the second part of the flange can be fixed to one another against the upper surface of the flange by inserting the screw into each of their hole and screwing the screw into the edge hole.
  • each hole of the plastic flange may not include initial tapping, the latter being made for the first time simply by screwing the connection screw.
  • the portable object is a wristwatch having communication means using radiofrequency waves. It is therefore expected to house an antenna in the bracelet, which is constituted by the conductive track. This antenna is connected to at least one electronic circuit for processing the information signals received or transmitted by the antenna.
  • a good seal is provided to connect the antenna to the electronic processing circuit while having a good behavior over time.
  • the specific tool for filling the cavity of the sealing material is guided by guide means provided in each sidewall portion to a determined distance from the bottom of the cavity, but below each flange passing through said cavity.
  • this avoids creating air bubbles below the flanges, which could lead to not guaranteeing a good seal once the sealing material has solidified.
  • the cavity is formed in the side wall from an upper edge of said wall in the vertical direction, the bottom of the housing having this side wall can be placed on a suitable mounting bracket to bring the specific tool from above to fill the cavity.
  • the sealing material in liquid form can extend over all the interior surfaces of the cavity by simple effect of gravity.
  • the figure 1a represents a schematic sectional view of the wristwatch 1 as a portable object.
  • This wristwatch 1 comprises a housing having an upper part or middle part 3 and a lower part or bottom 2, a bracelet provided with two strands 4 and 5 attached to the housing, and at least one button or control ring not shown.
  • the upper 3 and lower 2 parts are assembled one on the other in the closed position of the housing with one end of each strand 4 and 5 by conventional fastening means not shown in FIG. figure 1a .
  • Said ends of the strands 4 and 5 are wedged between the bottom 2 and the middle part 3.
  • An annular seal 17 is placed in an annular groove of the middle part to come into contact with an upper edge of a side wall 15 of the bottom 2 in order to to ensure the tightness of the closed housing.

  • the wristwatch also comprises electrical connection means which comprise in particular electrical contact flanges 8, which are in this embodiment in a number of 4 as shown in particular in FIG. figure 1b .
  • these flanges 8 are provided to electrically contact the contact pads 30 on the printed circuit board 10 with ends of at least one conductive track 6 and 7 disposed in each strand 4 and 5 of the bracelet.
  • the conductive track 6 and 7 of each strand defines an antenna for transmitting and receiving information in cooperation with the electronic circuit.
  • the electronic circuit 11, which is placed inside the case of the watch 1, comprises an information processing unit.

  • the intermediate part each pair of flanges 8 is secured by a sealing material 9 not shown in FIG. figure 1b , which is introduced into each cavity 26 as described below, in particular with reference to Figures 3a and 3b .
  • the sealing material is preferably a polymerizable adhesive or silicone.
  • This sealing material 9 is different from the plastic insulating material used in particular for the side wall 15. In this way, the sealing of said flange 8 through the side wall 15 is sealed, since the properties of the sealing material do not change over time in the same way as the side wall which is for example hard plastic.
  • the electrical contact flange 8 used as the electrical connection means is shown more clearly in FIG. figure 4 which represents a three-dimensional view of this flange, as well as Figures 5a and 5b .
  • This contact flange 8 is made from a strip of a good electrically conductive metal material, such as an alloy composed of copper. The thickness of this band may be of the order of 0.1 mm.
  • the flange comprises a first S-shaped portion 8a, a second portion 8b and the intermediate portion 8c which is intended to be attached through the side wall of the bottom of the housing by the sealing material.
  • the first S-shaped portion 8a of the flange 8 constitutes a compression spring.
  • the printed circuit board compresses with a determined force F each first portion of the flanges 8 at the contact pads of the printed circuit board. This makes it possible to establish a good electrical contact between the flange and the corresponding contact pad.
  • the first part 8a of the flange 8 thus compressed is shown in broken lines on the figure 5a .
  • the printed circuit board 10 rests on a spacer 19 separating it from the cell 14. This may also make it possible not to damage the first part of each flange 8 unnecessarily when the casing is closed.
  • the intermediate portion 8c and the second portion 8b of the flange are generally blade-shaped.
  • the second portion 8b of this flange is pierced with a hole 18 so as to be attached to one end of a conductive track as explained below.
  • the end of the second portion 8b of the flange is narrowed to facilitate mounting of the flange through the openings of the wall portions accommodating it before securing it with the sealing material.
  • a boss 29 may be made in particular by stamping or stamping in the intermediate portion 8c of this flange to be used to position said flange in openings in each side wall portion.
  • Each opening is thus made of sufficient size in said wall portions to facilitate the introduction of the second part.
  • the height of each opening may be for example 0.2 mm, while the thickness of the second part is 0.1 mm.
  • By against the height of the boss can be substantially equal to the height of each opening which allows to position the intermediate portion of the flange before the introduction of the sealing material in the cavity of the side wall.

  • Each hole can be self-tapped by the connection screw or may initially comprise a tapping.
  • Each threaded portion of the connecting screw 24 passes through a suitable hole 18 of the second portion of the flange 8 and a suitable hole 42 of the end of the corresponding conductive track 6 and 7 to be connected. Since the head of the screw is larger in diameter than the holes 18 and 42, the second portion of the flange and the end of the conductive track can come into direct contact with the upper surface of the insulating flange 20 by completely screwing each screw. connection 24 in the tapped holes 23.

  • Each electrical contact flange 8 is introduced from its second part, whose end is narrowed, through each opening 31 formed in the portions 27 and 28 of the side wall 15. Thanks to this narrowing of the second part and the fact that the thickness of the blade is almost twice as small as the height of the opening 31, the introduction of this flange is facilitated. Said flange 8 is thus introduced through the openings 31 from the inside of the housing until the hole 18 of the second part is positioned substantially coaxially with the tapped hole 23 formed in the flange 20. The intermediate portion of the flange is thus positioned in the apertures 31 of the portions 27 and 28 thanks to the boss 29 whose height is substantially equal to the height of each opening 31.
