Definitions

  • the invention relates to a radio clockwork according to the preamble of claim 1.
  • Non-housed radiation transmitters in the form of, for example, infrared light-emitting diodes can also be used as chips directly on a conductor lamination glue the circuit board and face it using a sheet bond wire running below to another conductor track of the same printed circuit board electrical connection.
  • the present invention is therefore based on the object of a radio-controlled clockwork Generic type to the extent that it is in particular smaller build up and easier to assemble.
  • a light barrier element mentioned in claim 1 namely, preferably the radiation transmitter, as a chip with lateral play inside the circuit board is laid in there and rests on a lamination or foil, both as a mechanical support, as an electrical connection and as a termination of the chip-receiving circuit breakout is used.
  • the gear train is expediently in an independently functioning one Gear block created that only after it has been equipped with the wheels on its two parallel to the wheels extending outer surfaces of the factory or Carrier plate with printed circuit boards for the light barrier elements (transmitter and receiver) is then occupied, which then somewhat in work plate or carrier plate openings protrude into it.
  • the carrier plate perforation is still freely accessible from the outside, so that here a marking the axis of the later light barrier, the carrier plate for A penetrating adjustment pin can be used inside the gear block.
  • One of the two elements parallel to the movement axis and thus transverse to the wheels oriented transmitted light sensor, preferably the one opposite the transmitter usually larger recipients, is best combined with the other electronic components of a radio clock electronic module on one (main) circuit board to be attached parallel to the wheels behind the carrier plate arranged; while the smaller one and due to its recessed mounting hardly Light barrier transmitters protruding beyond the PCB thickness on one (Auxiliary) circuit board is arranged, the dial side in the work plate of the already functionally assembled gear block is sunk.
  • the mechanical Connection of the two circuit boards with the gear block and the electrical connection between the two circuit boards is made by means of a electrically conductive anchor bolt parallel to the axis through the gear block, whereby the one of the two conductor tracks of the auxiliary circuit board to one of the two Conductors of the main circuit board are electrically connected and at the same time that Pair of circuit boards sandwiched against the opposite outer surfaces the intermediate gear block is pressed.
  • a parallel the pressure contact spring arranged for the anchor screw becomes the other of the two conductor tracks of the auxiliary and the main circuit board with one another on the same or via conductive access hatches on opposite sides contacted the respective circuit board.
  • the gear train 11 of the radio-controlled wristwatch movement 12 is completely functional in itself in a two-part, not necessarily box-shaped closed gear block 13 from each other and parallel to the wheels, profiled work and Carrier plates 14, 15 arranged. They are not necessarily stepless along one a level dividing line 16, saving a gear space 17 by means of at least one bridging the dividing joints 16 and rearward in the support plate 15 countersunk head clamping screw 18 parallel to the work axis 19 clamped together.
  • the minute shaft 20 is in a, journal bearing 21 in the Carrier plate 15 held and opposite from which the minute wave 20th concentrically surrounding hour tube 22 radially guided, which in turn has a central bore 23 protrudes in the work plate 14 and is rotatably supported radially therein.
  • the hour tube 22 is axially supported within the transmission space 17 by means of the hour wheel 22 molded or attached to the hour tube 22 24, on the one hand on the back 25 of the work plate 14 and on the other hand on the front end face 26 of a pinion 27 formed on the minute shaft 20 is supported.
  • the torque transmission from the minute shaft pinion 27 to the hour wheel 24 takes place by means of a change gear including change gear pinion, which in the drawing are not shown because their axis offset parallel to the pointer shaft axis 19 lies outside the longitudinal sectional plane shown in the drawing.
  • This is between a front and a rear journal bearing 31, 32 in the work plate 14 or held in the carrier plate 15 and equipped with an intermediate wheel 33, which with the (outside this cutting plane and therefore not shown) rotor pinion 34 of a stepper motor 35 driven in a time-keeping manner combs, which is arranged on the main circuit board 43 and with its pinion 34 in 113 protrudes.
  • the transmitter 37 a semiconductor diode with radiation in the visible or invisible spectrum, preferably in the near infrared spectrum, is mechanically held in front of the work plate opening 36.4 by means of an auxiliary circuit board 41, projecting somewhat into it.
  • the light barrier receiver 38 which is matched to that radiation spectrum, is arranged on the front or component side 42 of the main circuit board 43 located behind the carrier plate 15, projecting into a carrier plate opening 36.5.
  • the mechanical connection of the two circuit boards 41, 43 with the gear block 13 and the electrical connection of the two circuit boards 41-43 to one another takes place - with simultaneous additional bracing of work plate 14 and carrier plate 15 with each other - on both sides of the gear block 13 by means of a electrically conductive (metal or electrically conductive coated) anchor screw 44.
  • Their threaded shaft 45 engages in an internally threaded pillar 46, which is stored in the auxiliary circuit board 41 and in the exemplary embodiment on the latter front liner 47 is placed, for example soldered, so that the latter electrically via the anchor screw head 48 with the rear conductor track lamination 49 of the main circuit board 43 is electrically connected.
  • Axially parallel Akerschraub channel 50 extends parallel in close proximity a guide channel through the work plate 14 and the support plate 15 51 for a pressure contact spring 52 (preferably as outlined a coil spring) which are located on the front lamination 53 of the main printed circuit board 43 and supports forward on the back 54 of the auxiliary circuit board 41, here opposite whose backing 47 is isolated.
  • a pressure contact spring 52 preferably as outlined a coil spring
  • the spring 52 against the auxiliary circuit board 41 ends with a metallized access 55, via which the electrically conductive spring 52 is connected to the front liner 56 which is thus via the spring 52 to the front liner 53 of the Main circuit board 43 leads.
  • Auxiliary circuit board 41 only the mechanical bracket and the electrical connection of the front component of the light barrier 39 (here an unhoused light-emitting diode serves as the radiation transmitter 37) is for this module connected to the main circuit board 43 by means of the anchor screw 44 the lowest possible height in the direction of the pointer shaft and movement axis 19 to strive for. This is achieved in that the radiation transmitter 37 in a Opening 60 of the auxiliary circuit board 41 is recessed and therein on the rear Lamination 56 or one connected to this and the opening 60 bridging metal foil 61 rests, namely mechanically and electrically connected to it.
  • the LED chip hardly protrudes over the back one Lamination 47 of the auxiliary circuit board 41 in front and can therefore by means of a bond wire 62 in a relatively flat curve, so not very bulky, to the rear lamination 47 of the auxiliary circuit board 41 are electrically connected. Accordingly, the radiation-impermeable encapsulation 63 is not very thick and the concentration of the potting compound in the vicinity of the radiation transmitter 37, that is to say in the receiving opening 60, reduces the required casting compound and the potting area to about a third compared to potting one Chip component mounted and bonded flat on a surface.
  • Adjustment pin 65 can be used as an assembly aid.
  • the aperture holes 40 when inserting the idler shaft 64, the minute wave 20 and the hour tube 22 in the carrier plate 15 in succession pushed onto the adjusting pin 65, so that for the light barrier function relevant wheels are already exactly positioned when the gear block 13 by placing the work plate 14 on the support plate 15 and bracing by means of the screw 18 is closed.
  • the assembly adjustment pin 65 can now again from the carrier plate opening 36.5 can be removed and then put on the back of the electronic module main circuit board 43 immerse the light barrier receiver 38 to let. Furthermore, the auxiliary circuit board 41 with its radiation transmitter 37 under the Levels of the dial 57 inserted into the front depression 59 of the work plate 14 and mechanically and electrically via the anchor screw 44 to the opposite one Main circuit board 43 connected with the interposition of contact spring 52, the pinion 34 from the stepper motor 35 mounted on the main circuit board 43 combed into the teeth of the idler gear.
  • Radio clock movement 12 thus arises if, according to the invention, the gear train 11 functional between work plate 14 and support plate 15 with each other a screw 18 clamped and inserted adjusted with respect to the light barrier 39 to subsequently rearward the electronic module main circuit board 43 by immersing the stepper motor pinion 34 in the toothing of the idler gear 33 and on the front an auxiliary circuit board 41 for the light barrier transmitter 37 to put on the functionally closed gear block 13 and mechanically and electrically conductive by means of an anchor screw 44 axially parallel to the gear block 13 to connect outstandingly, with the interposition of one between the two circuit boards 41-43 clamped contact spring 52.
  • the front under the level of the dial 57 lying auxiliary circuit board 41 for the radiation transmitter 37 of the light barrier 39 applies particularly little if it is on a conductive Lamination 56 or film 61 is placed, which has a circuit board opening 60 bridged on the front, with electrical connection to the opposite PCB lamination 47 by means of a bonding wire 63 in particular flat arch and with a correspondingly flat casting hill 63 because of the overall height the radiation transmitter 37 hardly exceeds the thickness of the auxiliary printed circuit board 41, the radiation-permeable encapsulation 63 slightly in the work plate opening 36.4 can protrude.
