By thermally welding the electrode plate to the opening edge of the frame, the rigid metal plates 6 and 7 maintain a state in which a pressing force is applied to the electrode plate group.
発明が解決しようとする課題

に、落下衝撃によりコーナー部に破損、変形が生じ易い
という問題を有していた。Problems to be Solved by the Invention However, with the above-mentioned conventional configuration, it is difficult to ensure sufficient strength of the frame made of heat-fusible resin, so the corner portions are likely to be damaged or deformed due to drop impact. I had a problem.
本発明は、上記従来の問題点を解決するもので、落下衝
撃時にコーナー照の破損、変形を生じにくい密閉形鉛蓄
電池を提供することを目的とする。The present invention solves the above-mentioned conventional problems, and aims to provide a sealed lead-acid battery that is less likely to cause damage or deformation of the corner beams during a fall impact.

ルト接着剤を充填して同化・固定するものである。Means for Solving the Problems In order to solve the above-mentioned problems, the present invention provides that, when assembling a storage battery, when a frame is installed on a metal plate on which a negative electrode plate is placed, there is a gap between the frame and the negative electrode plate. The corners of the provided space are filled with sulfuric acid-resistant acrylic adhesive, epoxy adhesive, polyethylene adhesive, polypropylene adhesive, or other hot melt adhesive for assimilation and fixation.
作 用
この構成によって、落下衝撃時に最も弱い蓄電池のコー
ナー部が強化され、落下衝撃時の破損。Effect: This structure strengthens the corners of the storage battery, which are weakest in the event of a fall impact, and prevents damage during a fall impact.
変形に対して抵抗力の大きな密閉形鉛電池となる。This is a sealed lead-acid battery with high resistance to deformation.
なお、本発明においては、蓄電池の充放電の進行と共に
その外形寸法が増大する傾向にある正極板と枠体との間
に設けられている空間部には接着剤は充填しないので、
正極板の寸法の増大が発生しても何等支障を生じない。In addition, in the present invention, since the adhesive is not filled in the space provided between the positive electrode plate and the frame whose external dimensions tend to increase as the storage battery progresses in charging and discharging,
Even if the size of the positive electrode plate increases, no problem will occur.

In the figure, 4 indicates a negative electrode plate. 6 is a frame made of polyolefin synthetic resin such as polyethylene or polypropylene. 6 is a metal plate that seals the opening on the side of the frame;
Highly rigid materials such as aluminum, aluminum alloy, iron, and stainless steel with a thickness of 0.2 to 1. It is made of ORM metal, and a heat-weldable resin coating (film) having a thickness of about 0.1 fl and having sulfuric acid resistance is adhered to its inner surface. 1° is a hot melt adhesive such as an acrylic adhesive, an epoxy adhesive, a polyethylene adhesive, or a polypropylene adhesive having sulfuric acid resistance. After the frame 6 is installed on the metal plate θ on which the negative electrode plate 4 is placed, this adhesive 10 is filled into the corner part of the space 11 provided between the frame 6 and the negative electrode plate 4, and is assimilated. Fixed.
