Definitions

  • FIG. l is a fragmentary cross-sectional view of a conventional electric or electronic-timepiece having a battery
  • FIG. 2 is a fragmentary cross-sectional view of an electric or electronic timepiece having a battery accordingjto the present invention
  • FIG. 3 is a fragmentary cross-sectional view of atimepiece having a battery inserted upside down according to the present invention.
  • the present invention relates to the construction of an elec-' tric or electronic timepiece having a case back or a cover member for installing and removing a battery, wherein inversion of a battery does not cause a short circuit.
  • the conventionaltimepiece as .shown in FIG. I hasbeen commonly used.
  • This type of timepiece is so constructed that a concave opening for receiving a battery 1 is formed on a baseplate 2 and an elastic plate 4 insulated from the baseplate 2 by an insulating member 3 and carrying the battery I is provided in the central portion of the bottom of said concave opening.
  • the battery] isthen inserted normally in said concave of the baseplate 2 through an openingin the case 8.
  • a cover member 5 is electrically energized through the basepl ate .2 to the case 8 by grounding the positive lead terminal or the negative lead terminal of the-battery'to the movement.
  • An elastic plate 6 is fastened to the inner surface of the cover member 5.
  • the :cover member 5 with the elastic plate 6 is mounted on the case in such a manner that current is applied to the electric circuit by the tension exerted elastically by said plate 6.
  • the purpose of the present invention is to eliminate the above-mentioned defects and to provide an improved batterycarrying means for an electric or electronic timepiece.
  • the battery 1 consisting of the cylindrical portion of the positive pole and .the projected portion of negative pole is inserted in the concave opening formed in the baseplate 2 with said projected portion of the battery facing downward.
  • the battery 1 consisting of the cylindrical portion of the positive pole and .the projected portion of negative pole is inserted in the concave opening formed in the baseplate 2 with said projected portion of the battery facing downward.
  • the elastic plate 4 At the bottom of said concave opening, there is provided one elastic plate 4 insulated from the baseplate 2,
  • the battery I is carried by said elastic plate 4.
  • the elastic plate 6 is fastened to the outer periphery portion of the inner surface of the cover member.
  • the cover member 5 with the elastic plate 6 is then mounted on the case 8 so as to press against the outer periphery portion of the bottom of the battery] in such a manner that thecurrent is applied to the circuit from the bat- ..tery of the electric power source.
  • the insulating member 7 is fastened to the central portion of the inner surface ofthe cover member 5.
  • the main advantages of the present invention reside in the fact that even if the battery is inverted, a short circuit does not occur and the battery can be inserted again without wasting the energy stored therein. Further, the following defects which reside in -the conventional electric timepiece having a battery can be eliminated; namely, when the battery is inserted, its polarity is apt to be mistaken and it is difficult to show the direction to insert the battery.
  • a space may be provided in order to prevent the contact with the projected portion of the battery.
  • the present invention is not restricted to electric wrist watches and can be applied -to other electric products using batteries.
  • said' cover to be out of contact with said battery-projected por tion should said battery be inserted in said battery-receiving means with said projected portion facing said cover; and means for preventing electrical contact between said cover and said battery'projectcd portion when said battery is inserted in said batter-receiving means with said projected portion facing said cover.
