Description
【発明の詳細な説明】 産業上の利用分野 本発明は、鉛蓄電池の改良に関するものである。TECHNICAL FIELD The present invention relates to an improvement of a lead storage battery.
従来技術とその問題点 従来より例えば電気車用の鉛蓄電池においては、極群を
それよりも少し狭く設計した電槽に挿入したり、あるい
は耐酸性の合成樹脂又は緊塞板と称されるパルプ繊維板
やポリエチレン製のスペーサー等で電槽と極群との隙間
より厚いものを、極群の両外側面に配することにより、
極群に所定の緊圧力が加えられる様に設計されている。Conventional technology and its problems Conventionally, for example, in a lead-acid battery for an electric vehicle, the pole group is inserted into a battery case designed to be slightly narrower than that, or an acid-resistant synthetic resin or a pulp called a sealing plate. By arranging a fiberboard or polyethylene spacer that is thicker than the gap between the battery case and the pole group on both outer surfaces of the pole group,
It is designed so that a certain amount of pressure is applied to the pole group.
しかしながら、このうち極群に合わせて電槽を設計する
ものでは、機種毎に電槽金型を必要とするという欠点が
あった。他方、スペーサーを極群の両側面に配し緊圧力
を加えるものでは、機種によっては片面に２〜３枚から
６枚ぐらいもスペーサーを挿入しなければならないもの
があり、作業上で大きなネックとなっており、更にはス
ペーサーの製造コストも高く、従って電池全体のコスト
を引上げるという欠点があった。However, among these, the one in which the battery case is designed according to the pole group has a drawback that a battery case mold is required for each model. On the other hand, in the case of placing spacers on both sides of the pole group and applying tension, depending on the model, there are things that require inserting 2 to 3 to 6 spacers on one side, which is a big neck in work. In addition, the manufacturing cost of the spacer is also high, and thus the cost of the entire battery is increased.
このようなことを考慮し、熱溶着可能なバンドを使用し
緊圧を維持する方法が提案されたが、この方法ではスペ
ーサーが薄くなった分、電槽と極群とに間隔ができ、極
群が不安定な状態となる。In consideration of such a situation, a method of maintaining a tight pressure using a band capable of being heat-welded was proposed, but in this method, since the spacer is thinned, a space can be provided between the battery case and the electrode group, The group becomes unstable.
発明の目的 本発明は、上記従来の欠点に鑑み、なされたものであ

ことを目的とするものである。SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned conventional drawbacks, and an object of the present invention is to simplify the work and reduce the cost of the lead storage battery.

ある。Structure of the Invention That is, the present invention is a lead-acid battery, comprising an electrode group having an acid-resistant pressure plate on the outer side in the stacking direction of the electrode group and bound by a tape-shaped band made of synthetic resin, etc. Is inserted into the battery case and a resin foam is injected between the pressure plate and the inner wall of the battery case to fix the electrode group.
実施例 以下、本発明の一実施例について図面により説明する。Embodiment An embodiment of the present invention will be described below with reference to the drawings.

槽、７は電槽底部にある鞍、８は発泡ウレタンである。That is, the drawing is a partially cutaway perspective view of the lead-acid battery of one embodiment of the present invention. In the drawings, 1 is a positive electrode plate group in which a positive electrode is connected by a strap, 2 is a negative electrode plate group in which a negative electrode plate is connected by a strap, 3 is a separator and a glass mat interposed between the positive electrode plate and the negative electrode plate, and 4 is made of polyethylene. The pressure plate 5 is a band that can be heat-welded such as synthetic resin, 6 is a battery case, 7 is a saddle at the bottom of the battery case, and 8 is urethane foam.
正極板と負極板とはセパレータとガラスマット３を介し
て積層されており、その外側面には各々一枚の緊圧板４

且つ表面にシボ加工をしたものが用いられており、熱溶
着により両端が結合される。The positive electrode plate and the negative electrode plate are laminated via a separator and a glass mat 3, and one pressure plate 4 is provided on each outer surface thereof.
And is bound in band 5. Band 5
Is made of, for example, a polyolefin resin having high acid resistance and has a textured surface, and both ends thereof are joined by heat welding.
また緊圧板４は正極板、負極板やセパレータとガラスマ

た切溝を有しているので、該部で隙間のない構造になっ
ている。すなわちこれにより発泡ウレタン８が極群の下
に流入するのを防止することができる。Further, the pressure plate 4 is formed longer than the positive electrode plate, the negative electrode plate and the separator and the glass mat 3 and has a kerf that matches the saddle 7, so that there is no gap in the portion. There is. That is, this makes it possible to prevent the urethane foam 8 from flowing under the pole group.
発泡ウレタン８は、電槽内壁と緊圧板４との間に注入さ

レタン８は高価であり、且つあまり多量に注入すると、
その分だけ電解液量が制限されるので、電槽下部におい
て極群固定に必要なだけ注入するのが、好ましい。The urethane foam 8 is injected between the inner wall of the battery case and the pressure plate 4, whereby the pole group is fixed. There are no particular restrictions on the location or amount of the urethane foam 8 injected, but the urethane urethane 8 is expensive, and if too much is injected,
Since the amount of the electrolytic solution is limited by that amount, it is preferable to inject as much as necessary for fixing the electrode group in the lower part of the battery case.
以上、本発明の一実施例についてのみ詳細に説明した

体のものである必要はなく、一体となった構成としても
よい。Although only one embodiment of the present invention has been described in detail above, various embodiments of the present invention are conceivable without departing from the spirit of the present invention. For example, in the above embodiment, a heat-weldable band is used, and an example in which both ends of the band are joined by heat-welding has been described. However, in addition to this, fitting portions are formed at both ends for joining, or synthetic resin is used. It is also possible to use a coupling member. Further, the pressure plate and the band do not necessarily have to be separate members, and may be integrated.
更に本発明では発泡ホリプロピレンや発泡スチロールな
どの発泡ウレタン以外の発泡樹脂を使用することも可能
であるが、注入時の粘性が低いと不必要な隙間まで該樹
脂が流れ出ることになり、この点より比較的粘性が高い
発泡ウレタンは本発明の目的に照らして特に優れた性質
を有している。Furthermore, in the present invention, it is possible to use a foam resin other than urethane foam, such as foamed polypropylene and styrene foam, but if the viscosity at the time of injection is low, the resin will flow out to unnecessary gaps. Urethane foam having a relatively high viscosity has particularly excellent properties in view of the object of the present invention.

ているので、耐振性に優れた鉛蓄電池を提供できる。EFFECTS OF THE INVENTION As described above, in the present invention, the work procedure can be simplified and the cost can be reduced by reducing the number of spacers, and a low cost lead acid battery can be provided. Further, since urethane foam is injected only between the inner wall of the battery case and the pressure plate and has a gap at the bottom of the electrode group, even if the active material falls off, there is no short circuit until it is piled up to the height of the saddle, It is possible to provide a long-life lead-acid battery. Further, the pole group is band-tightened together with the pressure plate, and the pressure plate is fixed in the battery case by the saddle and the urethane foam, so that it is possible to provide a lead storage battery having excellent vibration resistance.
