Definitions

  • the invention relates to an electrical clock, in particular a battery-operated alarm clock, with a quartz-controllable drive, which is arranged together with the electrical circuit and the pointer mechanism on a printed circuit board which is accommodated in a housing.
  • the invention has for its object to simplify the contacting of the power supply in a clock of the type mentioned so that this can be done quickly and reliably and in particular by machine without special tools.
  • the two contact tracks extend over such a large area that they can be contacted at different points depending on the housing shape or battery size with contact springs arranged at different distances.
  • the circuit board can be connected particularly advantageously if the tracks of the circuit board of the electrical clock face the wall of the housing, since the contact springs can be fastened particularly securely between the wall and the circuit board.
  • the circuit board is simply inserted into the rear wall of the housing until it strikes the contact springs.
  • the mounting bracket thus creates the contact pressure to the contact springs at the same time.
  • the circuit board with the drive and the pointer mechanism is advantageously fastened in snap-in mounting in the housing.
  • the contact springs are advantageously punched and bent from one piece of material and, like the printed circuit board, are snap-fitted in the housing, for example in a specially provided housing opening for the power supply.
  • the contact tracks assigned to the contact plates are at least twice as wide as the other tracks on the printed circuit board. Beneficial about The strips completely paint an edge of the circuit board except for a central insulating piece that separates the electrical poles of the power supply.
  • the opening for the power supply can advantageously be closed with an elastically formable film, which advantageously extends over the entire length of the opening and has an attachment that is within reach after the power supply is inserted. This saves inner walls of the housing, since the film separates the battery from the inside.
  • the rear of the housing 1 of the clock shown in Figure 1 has an opening 2 in the lower area for inserting the battery. Above the opening 2, the rear wall of the housing 1 is shown broken open in order to make the circuit board 4 behind the rear wall visible. Some of the conductor tracks 5 located on the printed circuit board 4 are only sketched so that their pattern does not detract from the essentials of the invention.
  • Discrete components mounted on the printed circuit board 4 are connected via electrical lines 6 to the drive 7 mounted behind the printed circuit board, which can be seen in the sectional view in FIG. Furthermore, in front of the drive 7 there is a dial 8, not recognizable in FIG. 1, with the hands 9 of the clock arranged in front of it in a rotatable manner.
  • the power supply that is to say a battery or a correspondingly adapted power supply unit, is particularly wide by itself, without further measures, and is connected to the clock by means of conductor tracks 10 which extend over the entire lower edge of the printed circuit board 4, in the direction of battery poles and the contact tracks 10 acting contact springs 11 are fixed in the housing 1.
  • the contact tracks 10 differ from the other tracks 5 in that they are considerably wider than the normal conductor tracks 5 of the circuit board and extend over a large edge area of the circuit board 4. This makes it possible, for example, to insert batteries or power supplies of different sizes in the same housing. Dashed lines show that a battery 12 which is much smaller than the intended battery 3 can be used with adapted, different contact springs 13.
  • the circuit board of the invention can of course also be used in several housing shapes of different clocks with the same drive, the housing of which has openings for batteries on the back, but has different dimensions.
  • the contact springs for connecting the battery to the circuit board can namely be arranged in a very large area on the circuit board.
  • the different housings with the same circuit board 4 and thus also the same assigned drive can have in common that the opening for the battery is not closed in the direction of the circuit board.
  • the contact plates 11 or 13 can then be mounted from the opening side of the battery and the circuit board 4 together with the drive 7 from the scale opening of the housing in any order. This immediately results in a secure contact pressure of the electrically conductive parts pushed towards one another without additional connecting or clamping elements.
  • FIG. 2 can also be seen that the opening 2 of the housing 1 is covered by a film 14 which shields the interior of the housing 1 when a battery 3 is inserted.
  • a lug 15 of the film 14 protrudes to facilitate battery replacement, which can be covered by a cover 16 of the opening 2 shown in dotted lines.
