て電池としていた。2. Description of the Related Art Conventionally, this type of sealed lead-acid battery has been constructed by surrounding an electrode group 4 consisting of a positive electrode plate 1, a negative electrode plate 2, and a separator 3 with a frame 6 made of polyethylene, as shown in FIG. Two metal plates 7, 7', each of which has a film 6 made of a copolymer of ethylene and acrylic acid laminated on the inner surface in contact with the frame 4, are thermally welded to the end face of the frame 6 to seal it. , 8' and the claws 9, 9' of the metal plates 7, 7' are welded together.
' was used as a current collector, and a safety valve 1o was attached to the frame 6 to form a battery.
ここでの枠体６と金属板７１（７）’との熱溶着はこれ
らを第４図の如く箱形治具１２内に入れて熱板１３によ
って加圧することで行なわれていた。Thermal welding of the frame 6 and the metal plate 71(7)' here was carried out by placing them in a box-shaped jig 12 as shown in FIG. 4 and pressurizing them with a hot plate 13.
発明が解決しようとする課題
しかしこのような枠体６と金属板７１（７’）の外形寸
法をほぼ同じにしたものでは、第６図の如く熱溶着時に
金属板７がズして枠体６よりも外側へはみ出てしまい、
下記のような問題点があった。Problem to be Solved by the Invention However, in such a case where the outer dimensions of the frame body 6 and the metal plate 71 (7') are almost the same, the metal plate 7 may be displaced during heat welding as shown in FIG. It protrudes outside of 6,
There were the following problems.
■ 金属板が外側に出る事によって、寸法のバラツキが
大きくなる。■ Dimensional variation increases as the metal plate is exposed to the outside.
■ 保護のための熱収縮性チューブをかぶせ、これを熱
収縮させた際に、この外側へはみ出した金属板の角部に
よってチューブが破れて、金属板が露出し、短絡する危
険があった。■ When a heat-shrinkable tube was placed over the tube for protection and the tube was heat-shrinked, the corner of the metal plate that protruded outward would tear the tube, exposing the metal plate and causing a short circuit.
又このズレを吸収するためには、一般的には、金属板側
に溝なりスカートなりを付ければ良いが、フィルムをラ
ミネートするかぎりそれらの構造が設けられなかった。In order to absorb this deviation, it is generally sufficient to provide a groove or a skirt on the metal plate side, but as long as the film is laminated, such a structure has not been provided.
又金属板より枠体を大きくすれば良いと考えられるが、
実際には、枠体を大きくしても、金属板のズレを固定し
ないかぎり同様にズしてしまい、結果的には前記と同じ
であった。Also, it would be better to make the frame larger than the metal plate, but
In reality, even if the frame was made larger, the metal plate would still shift in the same way unless the shift was fixed, and the result was the same as above.
すなわち、枠体が溶けている間は、金属板系フリーの状
態であることが問題であった。That is, the problem was that the metal plate remained free while the frame was melting.
課題を解決するための手段
この問題を解決するため、本発明は枠体の外形寸法を金
属板よりも大きくするとともに溝の底部寸法が金属板の
外形寸法よりも小さい凹部を枠体の外周に設けたもので
ある。Means for Solving the Problems In order to solve this problem, the present invention makes the outer dimensions of the frame larger than the metal plate, and also creates a recess on the outer periphery of the frame, in which the bottom dimension of the groove is smaller than the outer dimension of the metal plate. It was established.

The peripheral edges of the metal plates 7, 7' laminated to the frame body 6 are thermally welded to the end face of the frame body 6. 1 for frame 6
A safety valve 1° and a recess 11 having an arcuate cross section extending from the outside to the inside are provided. The second method of assembling the battery is
As shown in the figure, the recess 11 of the frame 6 is fixed with a box-shaped jig 12, and the metal plate 7 is placed on top and heated with a hot plate 13 to be thermally welded. At this time, the box-shaped jig 12 can prevent the metal plate 7 from shifting. In other words, the frame 6 is smaller than the metal plate 7.
The size of the metal plate 7 is increased to prevent the metal plate 7 from protruding from the side, and to prevent the metal plate 7 from shifting.
A recess 11 is provided in the frame 5 so that the outer shape is smaller than that of the metal plate, and the recess 11 is used to fix the metal plate with a jig 12 to prevent displacement when heat welding is performed.
