Definitions
- the present invention relates to an electronic device for a room electronic or electromechanical watchmaking including a source of electrical energy, an electronic circuit and at least one connecting tab electrical ensuring an electrical connection between said source of electrical energy and said electronic circuit.
- the present invention also relates to a tongue of electrical connection intended to be mounted on a plate of a timepiece electronic or electromechanical to ensure an electrical connection between a electric power source and an electronic circuit of the timepiece.
- Electromechanical or electronic timepieces include usually a resonator, for example quartz, whose vibrations are maintained by an electronic control circuit powered by a source electrical energy such as a button cell battery.
- Timepieces electromechanical components also include a horometric movement controlled by the electronic control circuit associated with the resonator.
- the battery thus supplies the electronic circuit which maintains the vibrations of the resonator and, if necessary, supplies the driving impulses to a motor of the horometric movement.
- connection means are provided that form a power path.
- These electrical connection means forming the supply path generally include two electrical connection tabs respectively front and side, the first being arranged to come into contact on a first battery terminal (e.g. negative terminal), while the second is held in press the second terminal (eg the positive terminal) of the battery.
- a first battery terminal e.g. negative terminal
- the second terminal e.g. the positive terminal
- these electrical connection tabs are fixed to a plate by conventional fixing means, for example by riveting or by means of screws.
- fixing means for example by riveting or by means of screws.
- fixing means consisting of screws, especially on a plastic plate, can cause problems wear in addition to the disadvantages already mentioned.
- the present invention thus aims to overcome the drawbacks above by proposing a device comprising connecting means electric whose structure and fixing are simplified.
- connection means for an electronic timepiece not requiring complex fixing means.
- the means of connection electrical described in this patent include an electrical connection tab guided by a pair of lugs collaborating with a pair of openings arranged in the tongue. This electrical connection tab is however held in place only under the combined action of the battery and the electronic circuit. Without this action, the tongue is liable to disengage from the pins, which can in particular constitute a problem during the assembly of this tongue or when changing the battery.
- the present invention therefore further aims to provide a device comprising electrical connection means which do not require means of complex fixing, such as screws or rivets, and whose fixing in the room However, watchmaking is adequately and safely ensured.
- the present invention further aims to facilitate assembly and, where if necessary, the subsequent replacement of the electrical connection means in the room watchmaking.
- electrical connection means comprising a electrical connection tab intended to be mounted on a one-piece plate electronic or electromechanical watchmaking to ensure an electrical connection between the source of electrical energy and the electronic circuit of the timepiece, this electrical connection tab having a pair of openings intended for collaborate with a pair of fixing lugs secured to the plate of the part watchmaking.
- the connecting tab electric present further, arranged between the pair of openings, a section adapted to deform elastically in order to modify the spacing of the openings and allow engagement and retention of the connecting tab electric on the fixing lugs.
- the present invention thus relates to an electronic device for room electronic or electromechanical watchmaking whose characteristics are listed in claim 1.
- the solution recommended by the present invention thus facilitates the production and mounting of the means of electrical connection in a timepiece while ensuring that they are there correctly fixed.
- the present invention however provides a solution which is in besides very space-saving.
- the present invention also relates to a timepiece of the type electronic or electromechanical device comprising such a device, as well as a tab electrical link intended to be mounted in an electronic timepiece or electromechanical, the characteristics of which are listed in claim 8.
- a timepiece comprising a plate 2 forming a support, advantageously made of a material synthetic such as injected plastic.
- the timepiece also includes a electronic circuit 3 with which a quartz resonator is associated (for example represented).
- the latter further includes a horometric movement provided with a motor, such as a motor step by step, controlled by driving pulses emanating from the electronic circuit 3.
- the timepiece is also equipped with an energy source, formed in this example, by a battery 4 of the button cell type.
- This stack 4 provides the electrical energy necessary for the operation of the electronic circuit 3 which maintains the oscillation of the quartz resonator and, if necessary, the supply of motor of the horometric movement.
- This type of battery such as the button cell 4 is of a largely marketed and is extremely common in timepieces electronic and electromechanical.
- This pile 4 is essentially shaped cylindrical and has an edge or periphery 42 which has the shape of a cylinder portion, bounded on either side by two substantially planar regions of larger areas, respectively 44 and 46.
- One of these regions, in this example region 46 oriented towards the plate 2, as well as the cylindrical periphery 42 constitute respectively the negative (-) and positive (+) terminals of battery 4.
- Battery 4 is disposed in a cavity 22 formed in the plate 2, the negative terminal of the battery 4, that is region 46, being oriented towards the bottom of this cavity 22.
- the timepiece includes electrical connection means forming a supply path.
- These electrical connection means comprise on the one hand a front connecting tab electric 5 supported by plate 2 and forming the negative part of the path Power.
- a first end portion 51 of this connecting tab electric 5 ensures contact with the negative terminal 46 of the battery 4.
- a second end portion 52 of the electrical connection tab 5 provides electrical contact with a supply track 31 of the electronic circuit 3.
- the electrical connection means also comprise a tongue lateral electrical connection, not shown, forming the positive part of the path Power. This part can be carried out in a conventional manner and is within reach of the skilled person. However, it should be noted that this lateral tab of electrical connection can also be made according to the teaching of this invention.
- the electrical connection tabs can advantageously be produced in the form of stamped metal plates, for example from a metal plate spring steel.
- the end parts 51 and 52 of the electrical connection tab 5 are adapted to deform elastically under the effect of electronic circuit 3 and stack 4 so that these end portions 51 and 52 are held in contact against the negative terminal 46 of the battery 4 and the supply track 31 of the circuit electronic 3 after mounting.
- Figure 2 which shows a sectional view of a portion of the timepiece, is thus shown by way of illustration, the position of the end part 51 of the front electrical connection tongue 5 in its position rest when the battery 4 is not mounted in the timepiece.
- the front electrical connection tab 5 further comprises a pair of openings 55 and 56 partly forming means for fixing the tongue 5 on the plate 2.
- each opening 55, 56 is defined by a pair of designated electrical connecting tab fingers 55a, 55b and 56a, 56b respectively, these fingers being adapted to deform at less elastically to change the diameter of the opening corresponding. It will be understood from FIG. 2 that each pair of fingers 55a, 55b and 56a, 56b, respectively, "frame" and define the openings 55 and 56.
- finger is meant in the context of the present invention an extension of the tongue having a free end and an end integral with the body of the tab 5.
- the fixing means further comprise a pair of fixing lugs 25 and 26 secured to the plate 2 are used to hold the front tab of electrical connection 5 in place in the timepiece.
- the opening 55 is defined by the spacing between the fingers 55a and 55b of the tongue 5, these fingers being adapted to deform at less elastically in a plane substantially parallel to the plane of the tab 5 and plate 2.
- aperture 56 is defined by the spacing between the fingers 56a and 56b of the tongue 5, these fingers being as for them adapted to deform at least elastically in a plane substantially perpendicular to the plane of the tongue 5 and of the plate 2.
- the fingers 55a and 55b framing and defining the first opening 55 are arranged substantially parallel to each other.
- the tongue is sort of split over a certain length of so as to allow deformation in the plane of the tongue (that is to say in a plane substantially perpendicular to the direction of extension of the lug of fixing 25).
- a recess 55c can be practiced between the fingers as illustrated in figure 2.
- the fingers 56a and 56b framing and defining the second opening 56 are arranged so as to face each other and are arranged so that a deformation in a plane substantially perpendicular to the tongue (that is to say in a plane substantially parallel to the direction of extension of the lug 26) is made possible.
- the tongue of electrical connection 5 can be perfectly maintained by two pairs of fingers both adapted to deform in a plane perpendicular to the direction extension of lugs 25 and 26 or, alternatively, by two pairs of fingers both adapted to deform in a plane parallel to the direction of extension pins 25 and 26.
- the example illustrated in the figures shows a combination of these two "types" of fingers and is in no way limitative of the application of this invention.
- fingers 55a and 55b ensuring the maintenance of the tongue 5 on lug 25 can perfectly be replaced by fingers of the same type as fingers 56a, 56b, namely fingers liable to deform in a plane substantially parallel to the direction of extension of the lug 25. This applies also for the method of fixing the tongue 5 to the lug 26.
- the spacing of the fingers 55a, 55b and 56a, 56b is such that the diameter of the openings 55 and 56 thus defined is less than the diameter of the fixing lugs 25, 26.
- the spacing of the fingers 55a, 55b, on the one hand, and fingers 56a, 56b, on the other hand is modified by the presence of the corresponding fixing lug 25 and 26, that is to say that the fingers undergo a deformation (at least elastic) allowing the engagement then the maintenance of the electrical connection tab 5 on the fixing lugs 25 and 26.
- the electrical connection tab 5 can be held in place on the fixing lugs 25 and 26 by a pinching effect, that is to say under the action of restoring forces tending to return the fingers to their rest position.
- the fingers in metallic material can perfectly penetrate slightly into the material plastic, softer, of which the support 2 (or platinum) and the pins 25, 26, in order to firmly hold the tongue 5 in place.
- the lugs of attachment 25 and 26 may have a substantially cylindrical shape and include, in their lower part, respectively radial recesses 25a and 26a which engage the fingers 55a, 55b and 56a, 56b respectively.
- the elasticity of the fingers thus ensures the engagement of the electrical connecting tab 5 on the upper part of the fixing lugs 25, 26, the fingers 55a, 55b and 56a, 56b then engaging in the respective recesses 25a and 26a of the lugs of fixing 25 and 26.
- This solution advantageously avoids disengagement accidental electrical connection tab.
- the fingers can simply be arranged so as to allow the engagement of the tongue 5 on the fixing lugs 25, 26, the retention of the tongue being essentially ensured by the radial recesses 25a, 26a formed in the fixing lugs.
- fingers 55a, 55b and 56a, 56b thus contribute to maintaining the tongue by their engagement in the radial recesses 25a, 26a.
