Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a battery insulating plate mounting structure for an electronic watch.

Conventionally, in electronic watches, the maximum thickness of the watch is the battery part. Therefore, as long as the battery does not become thinner even if the components such as the receiver and circuit block are made thinner, if the watch is made into a composite watch, only the battery part will protrude. Alternatively, the overall thickness of the composite becomes thick due to the batteries, making it impossible to create a variety of designs. In addition, in the case shown in Fig. 1, in order to make the battery part as thin as possible, the battery lead plate 1, the battery insulating plate 2, the battery thickness 3 of the base plate, etc. are made thinner, but in this case, In order to maintain the contact pressure of the battery, the thickness of the lead plate cannot be made too thin. Furthermore, if the thickness of the base plate is made too thin, there is a problem in that the mechanical strength becomes weak. An object of the present invention is to fix the battery insulating plate to the hole or notch of the base plate in which the battery is placed using pins, fastening parts, etc., thereby solving the above-mentioned drawbacks. Next, the embodiment of the present invention will be explained in detail based on the drawings. First, FIG. The notch la is formed to be larger than the outer diameter of the battery.

Next, FIG. 3 is a sectional view taken along the line A-A' in FIG. 2, and the sectional structure around the battery section will be explained. 2 is a battery, and 13 is a back cover that is in contact with the battery 2. Reference numeral 5 designates a battery insulating plate, which is positioned by screw pins 3 and 4 driven into the base plate 1, and further includes upper portions 3a and 4.
It is fixed to the base plate 1 by being pressed by a.

Reference numeral 15 denotes a battery lead plate which is in the state 15a shown in the figure before the battery 2 is attached, and is in contact with the cathode portion of the battery 2, and is also in contact with the pattern 16a of the circuit board 16.

Further, since the base plate 1 is electrically connected to the positive voltage, it maintains insulation from the screw pin 3 and the battery lead plate 15 via the insulating frame 17. Numeral 18 is a screw for fixing the insulating frame 17, the battery lead plate 15, and the circuit board 16.

Reference numeral 19 denotes a receiver, which is fixed by a screw 201.

FIG. 4 shows a cross section taken along the line B-B' in FIG. . Reference numeral 9 denotes a small iron car, which engages with a pin le formed integrally with the base plate 1.

FIG. 5 shows another embodiment, which differs from FIG. 3 in the battery insulating plate mounting structure. The battery insulating plate 5 is the base plate 1
Screw pins 31 and 41 having a bulge portion driven into the
It is fixed between the back cover 13 and the base plate 1 by. 1
Reference numeral 9 denotes a receiver, which is fixed with a screw 20a.

A battery lead plate 15 is electrically connected to the pattern 16a of the circuit board 16 and is suitable for conducting to the cathode of the battery 2.

Further, since the battery lead plate 5 has a positive conduction to the base plate 1, the screw 18a and the screw pin 31 are structured so as not to be short-circuited by the insulating push 17a made of an electrical insulator. As described above, according to the present invention, only the battery, battery lead plate, and battery insulation frame constitute the dimensions of the cross-sectional structure of the battery section, so it is possible to omit the thickness of the base plate, and the battery protrusion can be reduced. It can be reduced.

In addition, the base plate does not require any rounding process for arranging the battery, and can be done by punching through press working, so the process of managing the remaining thickness of the base plate can be omitted. Furthermore, by forming a pin on the back side of the base plate of the battery insulating plate, it can be used as a guide pin for the bag member, and the manufacturing process can be streamlined by reducing the need for pin machining, holes to engage with the pin, and pin setting work. On the other hand, since the protrusion of the battery part is reduced, it has various effects such as eliminating design constraints caused by the protrusion of the battery part.
