て封口していた。Conventional technology In conventional sealed lead-acid batteries, one side is in close contact with a current collector plate laminated with a synthetic resin film material, and the other three sides are melted and tightly bonded to a synthetic resin frame to seal the pole part. The frame body around this pole column is composed of a recess formed from the outer circumferential surface and a resin plate of a bottom partition wall having a certain thickness, and a part of this bottom partition wall is melted to form a wall around the pole column. It was surrounded and sealed. When the sealing shape of the pole column melts over a wide range in the longitudinal direction of the pole column, the resin plate of the partition wall may be thick or relatively thin. When melt-sealing a wide area, the melt-sealing alone is used, and when a recess is formed and sealed by melting the resin partition wall, the recess is filled with an adhesive and sealed.
枠体に溶着される集電板は、その外周の大きさが枠体の
それとほぼ同じ大きさで枠体の外周の枠厚全体を溶かし
、固着していた。The current collector plate welded to the frame had an outer circumference approximately the same size as that of the frame, and was fixed by melting the entire thickness of the outer circumference of the frame.

観上の見苦しさだけでなく単電池としての外形寸法の精
度が保てなかった。Problems to be Solved by the Invention However, with this type of conventional configuration, the airtightness between the bottom partition wall of the frame recess of the pole column and the pole column to be sealed is unstable, and the molten material in the frame is not sufficiently sealed. It was not possible to wrap the column. Further, the melt-pressure bonding between the pole pole and the synthetic resin film material laminated to the current collector plate was also insufficient. Furthermore, welding burrs on the outer periphery that are generated when welding the frame and the current collector plate protrude on the outer periphery, which not only makes the appearance unsightly but also makes it impossible to maintain the accuracy of the outer dimensions of the cell.
このように外形寸法にばらつきが生じると、集電板は構

並べて使用する場合、互に集電板が接触してショート現
象を起こす危険性を有していた。If this variation in external dimensions occurs, the current collector plates are structurally connected electrically to the positive and negative electrode plates, so the current collector plates on both sides of the cell are charged as anodes and cathodes, respectively. As mentioned above, the outer dimensions of the frame and the outer dimensions of the current collector plate are the same and are welded together, so when these cells are used side by side on a flat surface, the current collector plates may come into contact with each other. There was a risk that a short circuit would occur.

ポット部周囲が完全な気密性があることは勿論のことで

もれてしまうことがある。On the other hand, when filling the concave part of the frame with adhesive to completely seal the pole part, it goes without saying that the area around the pot where the adhesive is placed must be completely airtight. However, even if there is a slit-like gap in the horizontal direction between the frame and the current collector plate, the adhesive will spread through this gap due to capillary action.
It may leak.

。Means for Solving the Problems In order to solve the above problems, the present invention provides a recess in a part of the frame, forms an extremely thin film part in a part of the bottom partition of the recess, and Slanted portions are provided on the facing side portions, and pole pillar portions protruding from the positive and negative electrode plates are melt-fitted to the ultra-thin film portions to extract electricity from the positive and negative electrode plates.

。That is, the ultra-thin film formed on a part of the bottom partition wall is easily melted by the electrode plates and pole pillars heated by a hot plate through the current collecting plate, and the melted resin provides airtightness around the pole pillars. ,
The thick part can sufficiently press the pole column against the laminate film surface of the current collector plate. In addition, since the sloped portion is provided, even if the electrode plate and pole pillar temporarily attached to the current collector plate are slightly misaligned in the width direction with respect to the ultra-thin film portion, there is a temporary sealing hole (recessed portion) to prevent adhesive leakage.

底部隔壁８の一部には、極薄膜部９を形成し７ている。In the figure, 1 is a positive electrode plate and 2 is a negative electrode plate constituting a unit cell, and a separator 3 is arranged between these positive and negative electrode plates 1.2 to form an electrode plate group. 4.6 is a current collector plate made of a gold maple plate laminated with a synthetic resin film material on one side.The electrode plate group is sandwiched from both sides with this laminated surface inside, and the entire periphery is covered with a synthetic resin frame. The current collector plates 4 surrounded by 6 and adjacent to each other
, 6 and the resin surface of the frame body 6 are thermally welded. 7 is the frame 6
A part of the bottom partition wall 8 of this recess is formed with an extremely thin film part 9 at four parts which are recessed inward from the outer circumferential surface.

けられている。Both sides of the ultra-thin film portion 9 have inclined surfaces 10, and the inclined surfaces 1
A protruding pole column portion 11 is melted and fitted within a range of 0 to extract electricity from the positive and negative electrode plates 1.2. The depth dimension t of the ultra-thin film portion 9 is approximately equal to the plate thickness dimension T of the pole column portion 11, and is set to approximately t≦T. One surface 12 of the pole column portion 11 is in close contact with a protruding convex portion 13 at a position corresponding to the surface 12 of the current collector plate 4, and the other surface is melt-fitted to the ultra-thin film portion 9 to form the pole column portion described above. The difference between the thickness T of the pole 11 and the depth t of the ultra-thin film portion 9 becomes a force that pushes the pole 11 outward, increasing the airtight force between the contact surfaces 13 and 12 of the pole 11 and the current collector plate 4. This also has the effect of increasing the welding airtightness around the pole column portion 11. However, if this force becomes too strong, that is, the difference in t (T) becomes large, the bottom partition wall 8 will not be completely melted during heat welding with the colander, and the pole part 11 will be pushed
This causes the convex portion 13 of the output current collector plate 4 to float, thereby disturbing the thickness dimension of the unit cell. Reference numeral 14 denotes a connecting portion that protrudes from the outer edges of the current collector plates 4 and 6 and is bent into a U-shape, and this connecting portion 14 is soldered or welded to the pole pole 11. 16
are welded ribs provided along the inner wall of the frame 6 over the entire circumference so as to protrude in the thickness direction of the frame 6, and are provided on both sides of the frame 6.

しても前記溶着バリ逃し溝１６で吸収できる。Reference numeral 16 denotes a welding burr release groove provided along the outer periphery of the welding rib 16 to store welding burrs, and further provided on the outer periphery of the groove is a current collecting plate periphery surrounding rib 17 that surrounds the outer periphery of the current collecting plate 4. Reference numeral 18 denotes a welding rib 15 which crosses the welding burr release groove 16 near the recessed portion 7 provided on the outer peripheral surface of the frame body.
This is an adhesive sealing rib that joins the current collector plate peripheral edge surrounding rib 17. Two to three ribs are provided. Even if melted welding ribs protrude in a crisp shape when the current collecting plates 4 and 6 are thermally welded to the frame body 6, they can be absorbed by the welding burr release groove 16.

したことになり、容易に接着剤漏れを起すことはない。In addition, when the current collector plate 4.6 is welded, the adhesive sealing rib 18 is also welded at the same time, so the recess 7 provided around the pole column is used as the adhesive injection pot for sealing the pole column. The airtightness against the spread to both sides is achieved by double or triple welding, and adhesive leakage does not occur easily.

で注入され固められる。An adhesive (not shown) is filled in the recess 7 to solidify and seal the current collector plate 4.6, the frame 6, and the pole column 11 as one body, thereby creating an airtight seal between the inside of the cell and the outside air. It enhances sexuality. A notch step 19 is provided at the tip of the pole column to form a U-shaped connection 1.
4 is fixed, a slight gap 20 is created between the pole pole 11 and the current collector plate 4, and the adhesive wraps around this part and seals the pole pole all the way around. Reliability is further strengthened. If the gap 20 is extremely narrow, air will enter the gap 20 and deteriorate the sealing characteristics of the pole post 11. The adhesive is injected up to the upper end of the current collector plate 4.6 and hardened.
この凹部７の底部隔壁８と極柱１１の溶着隙間から接着
剤が漏れ単電池の中部に流れ込むこともあるので前記し
た極薄膜部と極柱との気密性も重要な仮封口要素である
。Since the adhesive may leak from the welding gap between the bottom partition wall 8 of the recess 7 and the pole pillar 11 and flow into the middle part of the cell, the airtightness between the extremely thin film part and the pole pole is also an important temporary sealing element.

び組電池が提供できる。Effects of the Invention As described above, according to the present invention, the airtightness of the cell is achieved by ensuring temporary sealing without adhesive leakage due to adhesive injection into the recess around the pole column and by completely sealing the pole column with adhesive. If this is realized, it will be possible to produce single cells with high manufacturing process yield and reliability. Even in the manufacture of battery packs made from a combination of single cells, it is possible to prevent contact short-circuit accidents between single cells, and because the current collector plate is not located at the outermost periphery, problems as a product due to cracks in the metal current collector plate can be prevented, which increases the product value. We can provide high-quality single cells and assembled batteries.
