外はあまり見られない。2. Description of the Related Art A number of structures in which two metal plates are locked to each other have been found in the past, but generally, they are shown in Figs. 8a, b, c, d.
As shown in. In these, the pair of locking portions that are locked with each other are metal pieces that are overlapped and engaged with each other. Usually, the number of overlapping plates of these engaging portions is usually 3 to 4. From the viewpoint of strength, there are almost no two pieces that are attached to each other, and there are not many other than those by spot welding or adhesion.

ただし全体的な寸法縮小を行なって外形寸法に制約を加
えると当然内容積が小さくなり、セパレータに含浸され
ている電解液が絞り出されて排気弁から漏液する。The outer dimensions of the unit cell are determined by the anode plate, cathode plate, and separator that make up the unit cell. Normally, the separator is set larger than the electrode plate, so the outer dimension of the unit cell depends on the separator. . Since the separator is made of ultrafine glass fiber and is impregnated with the electrolytic solution, the dimension easily changes when an external force is applied by a protrusion or the like.
However, if the overall dimensions are reduced to limit the outer dimensions, the internal volume naturally becomes small, and the electrolyte solution impregnated in the separator is squeezed out and leaks from the exhaust valve.

出来る。However, if only the locking portion projects inward, the volume reduction is extremely small and the ratio to the total volume is small. Also,
By properly selecting the position of the protrusion and the positional relationship between the electrode plate and the separator of the unit cell, a pair of locking parts that lock the metal plates without reducing the size of the separator, that is, without changing the volume of the unit cell. Can be provided so as to project toward the inner wall of the metal plate.

The cathode column 7 is also connected to the cathode plate 7 and serves as an electrical output terminal of the unit cell.
The safety valve 8 is for discharging the gas generated in the unit cell 5. The bag-shaped thin film 9 is important for sealing the airtightness of the anode pillar, the cathode pillar, and the safety valve 8 portion for sealing the unit cell 5 from the outside air. The unit cells 5 are stacked while being fixedly adhered to each other on the surfaces that are in contact with each other with an adhesive or a double-sided tape (not shown) to form an assembled battery 10. 11 and 12 are this battery pack
Two metal plates that contact the entire surface from both sides of 10. The metal plates 11 and 12 are also reinforcing plates for applying a group pressure to each of the stacked elements of the unit cell 5. The metal plates 11 and 12 are flat portions 13 and 14
Bend each side of each to the inside to make a U shape,
End portions 17 and 18 of the bent portions 15 and 16 have projecting portions 19 and 20,
The protrusions 19 and 20 are composed of a pair of fitting portions 21 and locking portions 22. A hole 23 into which the tip of the locking portion 22 is inserted and engaged with the fitting portion 21
And, there is a stepped portion 24 in which the plate thickness has fallen inward by one step. Similarly, the locking portion 22 also has a plate thickness inwardly stepped inward from the bent portion 15 surface of the metal plate 11.

This is to make it easier to assemble when inserting into 1 and 12.
In the state where they are locked to each other, the metal plates 11 and 12 are stretched almost straight by the mutual repulsion force of the assembled battery under the group pressure, so that they do not swell from the side surface. That is, α = 0 °. The unit 25 of the assembled battery assembled in this way has a battery case 26 as shown in FIG.
And 27 are covered to complete the battery pack. This battery pack has battery terminal portions 28 and 29 and serves as a power supply terminal as a small sealed lead acid battery. These battery terminals 28,2
Lead wires (not shown) in which the poles of the internal unit cells 5 are connected and connected in series are wired in the terminals 9.

る。As described above, the assembled battery unit 25 sandwiched between the two metal plates 11 and 12 and reinforced and assembled, and the pair of engaging portions of the metal plates 11 and 12 on both side surfaces between the battery cases. Despite having the locking part, there is no protruding part, and it maintains a flat and flush condition, and the side surface of the unit cell 5 and the battery case 26, 27
The inner surface of the battery has a structure in which only one metal plate is present, and constitutes a battery pack with extremely high volume efficiency.

（第４図）のみで、電池特性にはほとんど影響しない。The above-mentioned four steps and locking parts of the fitting part are provided, but the side surface of the unit cell is pushed because it protrudes inward by the plate thickness. It is extremely small, and if this step and the locking part are aligned with the position of the end of the unit cell on the side of the electrode plate, the number of cavities of the unit cell is reduced (Fig. 4), and the battery characteristics are Has almost no effect.
