Definitions

  • the invention relates to a radio wristwatch according to the preamble of the claim 1.
  • a generic watch according to DE 93 18 224 U1 is the coil and cylindrical ferrite core existing long-wave antenna for receiving the coded absolute time information next to the circuit board of the electronic module arranged in a cavity in the watch case parallel to the bracelet connection, which is saved in a thickened croissant base.
  • This is particularly important for small wristwatch cases such as for women's wristwatches very short ferrite rod and a correspondingly low antenna sensitivity. Therefore, it is only exceptional if the reception conditions are very good or with one sensitive receivers receive usable time telegrams possible. However, they are easy to use, especially with high receiver sensitivity external or internal sources of interference such as the high-frequency clock generator in particular decodable for the operation of the processor.
  • the core is no longer a cylindrical bobbin, but a housing diameter essentially filling ferrite plate. It now also serves as a carrier for mechanical and electrical components as well as for switching the clock electronic module.
  • the antenna coil is there on a lateral extension arranged the ferrite plate.
  • Such a ferrite molding is expensive, however Manufacturing and critical in processing to accommodate the others mechanical and electrical clockwork components, and as a plate - especially with the local weakening to accommodate the clockwork components and the Antenna coil - it is very likely to break when subjected to impact.
  • the present invention is based on the object to create a magnetic long-wave antenna for a radio wristwatch, the one in terms of interference sensitivity and antenna sensitivity represents an optimal compromise between the known extremes and in the production can be handled easily and is characterized by high mechanical stability.
  • a layered of long soft iron slats runs very flexible coil core as a circular arc section along the edge of the (Main) circuit board for the electronic module of the radio clockwork.
  • the essence is firmly connected to the circuit board, which gives it high mechanical stability.
  • the course on the edge of the circuit board and thus in close proximity to the electrically non-conductive and magnetically non-shielding housing allows the greatest possible distance from the most critical internal source of interference, namely the clock generator to be arranged as diametrically as possible with respect to the antenna coil for processor operation.
  • the core should extend over an arc angle extend from well over 90 °. From about 120 ° the antenna performance is already very good.
  • the greatest effective length results from a semicircular arc, i.e. over 180 °.
  • the curved core extends over an even larger angle, up to the order of 240 ° and above. This does not result in growth the effective core length more, but still an increase in antenna sensitivity, because the ends of the coil core going beyond 180 ° look like field-collecting pollen pieces.
  • a memory a Primary battery; or an accumulator for clockwork operation from a photovoltaic Cell out
  • Those components are, in particular, a quartz-stabilized receiver circuit 14 for demodulating the telegrams distributed via longwave with the coded absolute time and a processor 15 for the Decoding of the time telegrams, for their comparison with the time currently displayed by the hands of the clock and for the correction of this time display in the event of deviations from the current time recorded by radio, as described in more detail in EP 0 180 155 B1 Processor 15 is stabilized by means of a further quartz crystal 16.
  • Various discrete capacitors 17, which are arranged in smaller and larger groups, are provided for capacitive circuits. Holes 18 serve to penetrate the shafts for the gears of the gear and pointer mechanism, which are not shown themselves.
  • At least one light barrier element 19 scanning the angular positions of certain wheels of the transmission block is arranged on the main circuit board 13.
  • a larger indentation 20 on the edge of the printed circuit board 13 of the electronic module serves to accommodate a button-shaped memory 21 for the operation of the electronic module, that is to say the receiver, processor and drive circuits.
  • This memory 21 can be a primary battery or a chemical or electrical memory (accumulator or capacitor) for operating the clock circuit, for example with a photovoltaic cell.
  • Spring tongues 24 end via recesses 22 in the course of the boundary 23, which can be actuated from outside the watch case 11, for example by means of plungers, in order to trigger a switching function, for example in the processor 15, by bending until they abut against a mating contact 25 fastened to the printed circuit board 13.
  • the spring tongues 24 are preferably placed together at reference or ground potential in order to get by with a common electrical and mechanical connection to the edge of the printed circuit board 13.
  • the stepper motor 30 for the time-keeping movement of the pointer mechanism is oriented as far as possible in such a way that its field coil is oriented approximately transversely to the antenna coil 27. Even if the receiver 14 is switched on offset with respect to the control of the stepping motor 30 to avoid reception interference, such magnetic decoupling of the two closely adjacent coils contributes to further reliability of the reception operation.
  • the receiver circuit is for receiving the time telegrams distributed via long wave 14 namely connected to a magnetic antenna 26. That points in the manner of a loop antenna, a coil 27 on which by means of a capacitor 17 is matched to the carrier frequency of the time transmitter. To increase the The antenna 27 is sensitive to the coil 27 by a laminated core 28 from a stack of flexible strips of soft magnetic material of high permeability, such as leaf-shaped amorphous metals in particular. The across the cross section this core 28 applying coil 27 dips into a recessed or recessed space 29 at the edge 23 of the circuit board 13, so that the the coil 28 emerging core 28 along the edge 23 of the circuit board 13 this lies on.
  • the core 28 is stacked so that the individual strips alongside stand on their side edges and in the circumferential direction of the circuit board edge 23 are curved.
  • the core 28 results when the bow of the bow is approximately through the center the round printed circuit board 13 runs, so if the curved lamellar core 28 sweeps an angle of 180 °.
  • a larger angle, like the one shown Example trap does not extend the effective antenna length, but increases nevertheless the antenna sensitivity, because these protrude over 180 ° ends of the laminated soft iron core, like pole shoes, have a field-strengthening effect Reduce the directional sensitivity of the antenna coil somewhat.
  • the one that passes through the antenna coil 27 is laminated Soft iron core 28 according to the cross-sectional geometry of the inner wall of the housing 11 or the course of the circuit board edge 23 bent and the Coil 27 by moving on the core 28 or by capacitive wiring (17) matched to the fixed transmission frequency of the time transmitter (in particular DCF 77).
  • the core 28 is used to fix the coil position and the arc geometry including coil 27 inserted into a potting tool and with synthetic resin or other Soaked adhesive.
  • the thus hardened composite 27-28 is in your free space 29 protruding antenna coil 27 on the edge 23 of the circuit board 13 glued; or the circuit board 13 is used for further curing as a further Composite component 13-27-28 placed dimensionally on the potting tool.
  • the arrangement combines an extremely small space requirement with an extremely stable one Attachment at the cheapest possible distance from the main source of interference (the processor 15 with the quartz crystal 16). Besides, the is so curved and attached core 28 by practically the entire length of the support against the closely adjacent watch case 11 optimally against mechanical stress protected.
