Description

[Detailed Description of the Invention] The present invention relates to an improvement in the circuit structure of an electric portable watch.

Conventionally, a circuit block composed of a circuit board and an electrically conductive member attached to the circuit board by means such as resin caulking has been arranged in such a way that both the circuit board and the electrically conductive member are separated from adjacent members in a plane, or In the present invention, the arrangement of the circuit block and the members adjacent to the circuit block is changed so that the circuit board is arranged so that the members adjacent to the circuit block escape in the plane direction, and the electrical The conductive member overlaps the member adjacent to the circuit block in plan view.

By configuring it so that it escapes in the cross-sectional direction, it is possible to effectively utilize space and make the electric portable watch thinner and smaller.

The details of the present invention will be explained below with reference to FIGS. 1 to 3.

FIG. 1 is a drawing showing a conventional embodiment.

The electrically conductive member 1 is fixed to the circuit board 2 by means such as resin caulking 2a, and is equipped with electronic elements to form a circuit block.

Reference numeral 4 denotes a member adjacent to the circuit block, which is a mandarin pressing in this drawing.

5 is a mandarin duck, which is engaged with the mandarin duck pusher 4.

Here, the circuit board 2 and the electrically conductive member 1 are arranged so that the bent portion 4a of the mandarin pusher 4 is also spaced apart in a plane.

FIG. 2 is a sectional view showing another conventional embodiment, in which 1 is an electrically conductive member, which is fixed to a circuit board 2 by means such as resin caulking, and is equipped with electronic elements to form a circuit block. .

Reference numeral 4 denotes a member adjacent to the circuit block, which is a mandarin pressing in this drawing.

Here, the mandarin press 4 is arranged so as to separate from the circuit board 2 and the electrically conductive member 1 in cross section.

Figure 1. According to the structure shown in Fig. 2, when arranging a circuit block and a member adjacent to the circuit block, one circuit block must be completely separated from the member adjacent to the circuit block in plan view or in cross section.・As a result, the space is not efficient and the watch body becomes larger in plan, or the gaps between parts become tighter and the watch body becomes thicker in cross section, making it difficult to utilize narrow spaces effectively. Ta.

Fig. 3 is a drawing showing an embodiment of the present invention, in which Fig. 3a is a plan view and Fig. 3-b is a sectional view.

Reference numeral 1 denotes a battery conductive member, which is fixed to the circuit board 2 by means such as resin caulking, and is equipped with electronic elements such as a capacitor 3 to form one circuit block.

4 is a member adjacent to the circuit block, which in this embodiment is a mandarin press.

Here, the bent portion 4a of the mandarin press 4 allows the circuit board 2 to escape in a plane, and overlaps with the electrically conductive member 1 in a planar manner, allowing it to escape in a cross-sectional view.

According to this structure, electrically conductive members can be placed even in areas where there is no circuit board, so when parts such as mandarin pushers, which are located approximately at the same cross-sectional level as the circuit board, are placed adjacent to the circuit block. is the most effective and requires almost no space loss.

Further, by arranging the electrically conductive members in a bridge shape as in this embodiment, the circuit board can be reinforced with the electrically conductive members, and the strength of the circuit board can be ensured even if the circuit board is cut out.

In the present invention, if the member adjacent to the circuit block is an insulating material such as plastic, it may be placed in contact with the electrically conductive member, which further increases the advantage in terms of space.

The present invention is as described above, and the electric portable watch is small.

This effect is significant in today's world where devices are becoming thinner.
