Description of the Related Art In recent years, a large number of rechargeable electronic devices have been commercialized in which energy generated by a solar cell or the like is charged and driven in a storage unit such as a secondary battery or a capacitor disposed in the electronic device. For connection of the electrode from the power storage unit, a structure in which a lead plate is welded to the power storage unit and power is supplied through the lead plate is generally adopted. This is to prevent the risk of the primary battery being charged and exploding due to erroneous assembly of the unchargeable primary battery.

る。FIG. 6 is a partial sectional view of a rechargeable electronic timepiece, which is an example of a conventional rechargeable electronic device. In FIG. 6, reference numeral 1 denotes a button-type rechargeable and rechargeable secondary battery,
A negative lead plate 2 is resistance-welded to the negative electrode can at a welding portion 2b to form a secondary battery block 9. The secondary battery block 9 is housed in a plastic base plate 3. Reference numeral 4 denotes a connection spring for establishing conduction between the minus lead plate 2 and the composite circuit 6, and is positioned on the boss 3a of the base plate 3.

一次電池が誤って充電されて破裂する事はない。The connection spring 4, the composite circuit 6, and the circuit support plate 5 are stacked and fixed by fastening screws 7. Since the secondary battery 1 and the negative lead plate 2 are integrated by welding, even if the secondary battery block 9 is removed from the movement at the time of repair or overhaul and the primary battery that cannot be charged is mistakenly installed, the negative lead plate 2 can be used. Since there is no contact, the contact with the composite circuit 6 cannot be made and the clock does not operate. Therefore,
There is no possibility that the primary battery is charged accidentally and exploded.

２ｃを設けているものも多い。The contact portion 2a of the negative lead plate 2 protrudes relatively largely from the outer shape of the secondary battery 1 in order to prevent a short circuit with the positive electrode of the secondary battery 1 and in consideration of the stability of the spring contact. In general, the planar shape of the contact portion 2a often has a special shape corresponding to an individual movement, depending on the arrangement relationship of the other components of the movement. Also, a secondary lead plate 2 is attached to the secondary battery 1.
In many cases, in addition to the contact part 2a, another positioning part 2c protruding outside the outer shape of the secondary battery 1 is provided in addition to the contact part 2a for positioning when welding.

The contact portion 2a of the connection spring 4 is pulled out substantially straight from the secondary battery 1 so that the contact portion 4a of the connection spring 4 is vertically bent in order to prevent the contact with the minus lead plate 2 from coming off. . In order to prevent the contact portion 4a from protruding from the lower surface of the movement, it is necessary to secure a space in a cross section to some extent under the secondary battery block 9.

の切り替え作業では品質的にも安定しにくい。However, in the above-described structure, the minus lead plate 2 has a special shape unique to the movement. Therefore, when a rechargeable electronic timepiece other than the conventional example is developed, the movement of the movement is difficult. Due to the arrangement of parts, it is necessary to newly install a negative lead plate with a unique shape. Therefore, the welding jig for welding the negative lead plate to the secondary battery must also correspond to various shapes,
It is necessary to prepare several types. As a result, it takes time to switch the welding jig or the like, which increases the cost, and it is difficult to stabilize the quality in various kinds of switching work.

As the types of components increase, the complexity of component management also increases. Further, in the conventional example shown in FIG. 6, the contact portion 4a of the connection spring 4 that makes contact with the minus lead plate 2 is bent downward and protrudes downward, so that the thickness of the movement increases, so that the movement is increased. It is difficult to reduce the thickness of the device.

FIG. 2 is a perspective view of a power storage block. First, a sectional arrangement structure of the present embodiment will be described with reference to FIG. In FIG. 1, reference numeral 1 denotes a secondary battery that can be repeatedly charged and discharged, and although not shown, serves as an energy source that stores energy generated by a solar cell and drives a timepiece.
The secondary battery 1 has the same button shape as a silver oxide battery used in a normal electronic timepiece. A negative lead plate 8 is resistance-welded to the negative electrode can of the secondary battery 1 to form a secondary battery block 9.

Is resistance-welded to the negative electrode can at a welding point 8b. The contact portion 8a of the negative lead plate 8 is slightly pulled out to the outside of the outer shape of the secondary battery 1, and its tip is bent substantially perpendicularly to the positive electrode direction.

である。The projecting amount of the contact portion 8a from the secondary battery 1 is
It is desirable to reduce the size as much as possible in order to increase the versatility to other movements, and it is appropriate to set the gap A between the contact portion 8a and the side surface of the positive electrode can of the secondary battery 1 to 1.0 mm or less. However, if the gap A is set too small, there is a risk that the negative lead plate 8 and the positive electrode can of the secondary battery 1 may be short-circuited. Therefore, the dimensional tolerance of the parts and the positional accuracy of welding are taken into consideration. , 0.2 mm or more. Although the vertical bending amount B of the contact portion 8a is almost no problem from the viewpoint of versatility as long as it is within the thickness range of the secondary battery 1, it is appropriate to set it to about 0.4 mm to 1.0 mm.

ーブメントに固定している。The secondary battery block 9 is disposed on a plastic base plate 3, and the shoulder of the upper surface of the secondary battery 1 is supported by a metal circuit support plate 5. Reference numeral 10 denotes a connection spring for establishing conduction between the negative lead plate 8 and the composite circuit 6, and is positioned by the boss 3a of the base plate 3.
The contact portion 10a of the connection spring 10 for making an electrical connection with the minus lead plate 8 is bent vertically downwards of the movement, and has a structure in which it comes into contact with the contact portion 8a of the minus lead plate 8 on the surface, thereby improving the reliability of conduction. Is secured. The circuit support plate 5 holds the connection spring 10 and the composite circuit 6 from the upper surface side and fixes them to the movement.

Accidents such as rupture due to charging of the unreachable primary battery can be prevented.

可能な汎用部品化する事ができる。According to the present embodiment, in the secondary battery block 9, the contact portion 8a of the minus lead plate 8 only slightly protrudes from the secondary battery 1 by one point. Not only can it be used, but it can also be relatively easily arranged on a rechargeable electronic timepiece having another structure.
That is, the secondary battery block 9 can be made a general-purpose component that can be used for various movements.

ントの厚さを削減することができる。Further, since the contact portion 8a of the minus lead plate 8 is bent upward, the contact portion 1a of the connection spring 10 is bent.
The downward bending amount of 0a can sufficiently secure the conduction with the minus lead plate 8 reliably without extending the tip to a position where the tip protrudes from the lower surface of the secondary battery block 9 in cross section. That is, the thickness of the movement on the lower surface side of the secondary battery block 9 can be reduced.

FIG. 3 is a perspective view of a power storage block. In FIG. 3, a negative lead plate 13 is resistance-welded to the secondary battery 1 at a welding portion 13b to form a secondary battery block 15. The secondary battery block 15 is held on a plastic base plate 3.

And is positioned by the boss 3a of the main plate 3. The composite circuit 6 and the connection spring 14 are pressed from above by the circuit support plate 5. As shown in FIG. 4, the secondary battery block 15 has a negative electrode can of the secondary battery 1 and a disc-shaped minus lead plate 13 having substantially the same shape as the outer shape of the secondary battery 1 welded to the negative electrode can at a welding portion 13b. That is, in the present embodiment, the outer shape of the secondary battery 1
There is no part where 3 projects. The contact portion 14a of the connection spring 14 is pressed from the lower surface of the minus lead plate 13 to establish electrical continuity.

てしまう心配はない。The contact portion 14a conducts at a position close to the outer shape of the negative lead plate 13, that is, at a position separated from the negative electrode can of the secondary battery 1. Therefore, even if the unchargeable primary battery having the same shape as the secondary battery 1 is erroneously incorporated, the contact portion 14a of the connection spring 14 abuts on the positive electrode can of the primary battery and the negative electrode cannot be electrically connected. Therefore, there is no worry that the primary battery is charged.

る。As described above, according to the second embodiment, the secondary battery block 15 has no protruding portion in the outer shape of the secondary battery 1 even if the minus lead plate 13 is welded. Almost the same as the external shape of the secondary battery 1. Therefore, it can be easily mounted on various types of movements. Also, the work of welding the minus lead plate 13 to the secondary battery 1 can be performed at the same time because the outer shapes of the secondary battery 1 and the minus lead plate 13 are almost the same, and it is not necessary to define the rotation direction. Workability is very good.

4 has a drawback that the thickness of the movement is increased as compared with the first embodiment because the conductive contact is formed from the lower side of the minus lead plate 13.

路６の電気的導通を取っている。As a structure in which a non-rechargeable primary battery is not incorporated in a rechargeable electronic timepiece, the following method without using a minus lead plate can be considered. A third embodiment will be described with reference to FIG. FIG. 5 is a cross-sectional view of a main part showing a third embodiment. In FIG. 5, reference numeral 1 denotes a secondary battery, the lower side of which is held by a plastic base plate 3 and the upper side of which is held down by a circuit support plate 5. Reference numeral 16 denotes a minus receiving spring, which is positioned by the boss 3a of the main plate 3. The negative receiving spring 16 establishes electrical continuity between the negative electrode of the secondary battery 1 and the composite circuit 6.

接する必要が無い。After assembling into the above structure, welding is performed at the welding portion 5a of the circuit support plate 5, and the circuit support plate 5 is welded.
And the secondary battery 1 are integrated so that they cannot be disassembled. In other words, even if the circuit support plate 5 is disassembled and a non-rechargeable primary battery is installed in place of the secondary battery 1, the secondary battery 1 is welded and integrated when the circuit support plate 5 is installed, so that it is assembled first. It cannot be installed because it interferes with the primary battery. With this method, there is no need to weld a minus lead plate or the like to the secondary battery 1 in advance.

サービス用を含め部品管理上の効果は大きい。As described above, according to the present invention, one kind of power storage block can be used for various rechargeable movements. As a result, even in the operation of welding the minus lead plate to the electricity storage block, only one kind of positioning jig needs to be prepared, and furthermore, there is no need for man-hours for switching, so that the welding cost can be greatly reduced. In addition, since one type of component is produced in large quantities, it is considered that the quality is stable. In addition to welding work, there is only one kind of feeder to be incorporated into the movement, so assembly costs can be reduced. If parts are standardized, the effect on parts management including after-sales service is great.
