正極側のみ電池側面で電気導通をとるため、次の
様問題が生じる。 In the conventional battery structure, the battery is installed in the cross-sectional direction of the device, and as shown in FIG. 2, electrical continuity is established only on the top and bottom of the battery or on the positive electrode side at the side of the battery, resulting in the following problems.

(1) 電池の平面サイズより大きな電池ぶたが必要
で、電池ぶたの固定部も含めると電池が占める
面積が大きくなる。(1) A battery cover that is larger than the flat size of the battery is required, and when the fixing part of the battery cover is included, the area occupied by the battery becomes large.

It is. 5 is an insulating member. The flat battery 1 is pushed in from the opening provided on the side of the case 2 in a planar direction, and the sealing part 1d is inserted so as to push open the battery connection terminals 3 and 4. In the assembled state, the battery connection terminals are connected as shown in the figure. is fixed while pressing against the sealing part of the flat battery. The thickness of the sealing part is approximately 0.2 mm for batteries currently being commercialized with a thickness of 0.5 mm, and if continuity is established at this part as in this example, the total thickness of the sealing part is 0.76 mm, like an IC card. Even if the battery is thick, a structure in which the battery is pressed from above and below is possible. Furthermore, as shown in Figure 3, if the positions of the battery connection terminals 3 and 4 are shifted in plan, the sealing part of the battery will be twisted, so the gap △ between the battery connection terminals 3 or 4 and the case 2 will be Each can be made larger, the thickness of the battery connecting terminal can be increased, and the bending radius of the tip of the battery connecting terminal can be increased so that the battery connecting terminal does not get caught when the battery is inserted. In addition, the sealing part of a flat plate battery generally has a cross-sectional recess as shown in the figure, so by pressing this part with the battery connection terminal, you can obtain stability of conduction and a click feeling when inserting the battery. You can also do it. In this invention, we have given an example in which a metal spring is used for the battery connection terminal, but one side is
Direct continuity can also be achieved with a circuit board or the like. still,
The insulating member 5 makes it easier to hold the battery when inserting it by holding the sealing part of the battery as shown in Fig. 1, and also serves as a battery cover so that it can be assembled into the case as shown in Fig. 3. In this state, push the battery into a position that will ensure continuity. Furthermore, when taking out the battery, the sealing part 1d is exposed from the case 2, making it easier to take out the battery. Furthermore, if the structure is such that the sealing part 1d is held between the insulating member 5, it becomes easier to take out the battery, and by making the shape and appearance of the insulating member asymmetrical, it is possible to prevent the positive and negative electrodes from being assembled in reverse. can also be done easily.
