Description
【考案の詳細な説明】 本考案は鉛蓄電池の短絡防止についての改良に関する。[Detailed explanation of the idea] The present invention relates to improvements in preventing short circuits in lead-acid batteries.
従来、鉛蓄電池を寿命に至らせる原因としては極板群に
おける陽極板と陰極板の短絡が殆どで、特に極板群底部
に発生する短絡が多い。Conventionally, the short circuit between the anode plate and the cathode plate in the electrode plate group is the most common cause of the end of the life of a lead-acid battery, and short circuits occurring at the bottom of the electrode plate group are particularly common.
極板群底部の短絡原因は、陽極板及び陰極板から離脱し
た活物質の一部が陰極板の足部に電着し、次第に成長し
て陰極板足部に隣接する陽極板底部にまで至り、短絡し
て電池を寿命に至らせでいるものが殆どである。The cause of the short circuit at the bottom of the electrode plate group is that part of the active material separated from the anode and cathode plates is electrodeposited on the foot of the cathode plate, and gradually grows to reach the bottom of the anode plate adjacent to the foot of the cathode plate. In most cases, short circuit occurs and the battery reaches its end of life.
本考案はこれら極板群足部に発生する短絡を防止し電池
寿命の改善を図る事を目的とするものである。The purpose of the present invention is to prevent short circuits occurring at the legs of these electrode plates and to improve battery life.
本考案の一実施例を説明する。An embodiment of the present invention will be described.
電槽１の鞍部２の上面に肉厚が薄く上に広がった柔軟部
３を有する凹部４を備え、該凹部４にエポキシ樹脂５を
充填した上に極板群６の足部７が加圧載置され、前記柔
軟部３が極板群６の押圧により押し広げられ且つ隔離板
６ａの下端６ａ−１が極板６ｂの下端６ｂ−１の下方に
位置した状態で極板群６の足部７周辺をエポキシ樹脂５
で包覆して鞍部２に固着してなる。A recess 4 having a thin wall and a flexible part 3 extending upward is provided on the upper surface of the saddle 2 of the battery case 1, and the recess 4 is filled with epoxy resin 5, and the foot 7 of the electrode plate group 6 is pressed. The feet of the electrode plate group 6 are placed in a state where the flexible portion 3 is spread out by the pressure of the electrode plate group 6 and the lower end 6a-1 of the separator plate 6a is located below the lower end 6b-1 of the electrode plate 6b. Apply epoxy resin 5 around part 7.
It is covered and fixed to the saddle part 2.
エポキシ樹脂５は熱を加える力嘲然放置するかして硬化
させる。The epoxy resin 5 is cured by applying heat or by leaving it alone.
その結果陰、陽画極板の下端同志間の距離が長くなって
極板群６の足部７周辺の短絡の発生が少なくなった。As a result, the distance between the lower ends of the negative and positive electrode plates is increased, and the occurrence of short circuits around the foot portion 7 of the electrode plate group 6 is reduced.
本考案は上記の構造を有することにより、下記の効果を
有する。By having the above structure, the present invention has the following effects.
１ 短絡の最も発生しやすい極板群の足部周辺を樹脂で
覆い且つ隔離板の下端を極板の下端より下方に位置させ
ることにより短絡が激減し電池寿命が改善できる。1. By covering the periphery of the feet of the electrode plate group, where short circuits are most likely to occur, with resin and positioning the lower end of the separator plate below the lower end of the electrode plate, short circuits can be drastically reduced and battery life can be improved.
２ 極板群がその足部周辺が電槽の鞍部に固定されるた
め、極板群を構成する陽極板、陰極板、隔離板等のずれ
が無くなり極板群の側部及び上部の短絡も減少できる。2. Since the electrode plate group is fixed around its feet to the saddle of the battery case, there is no misalignment of the anode plate, cathode plate, separator plate, etc. that make up the electrode plate group, and short circuits on the sides and top of the electrode plate group are avoided. Can be reduced.
３ 電槽鞍部の凹部が上に広がった柔軟部を有するため
、該凹部への樹脂の充填する際の作業性力吠幅に改善さ
れ、また極板群の陰、陽極板の足部の位置に誤差が生じ
ても、そのための凹部および足部の精密な稿正が不要と
なり、生産性が極めて向上すると共に極板群の足部周辺
と凹部との固着強度にバラツキがなく、安定した固着状
態を維持する。3. Since the concave part of the battery case saddle has a flexible part that spreads upward, the workability when filling the concave part with resin is improved, and the position of the negative and anode plate feet of the electrode plate group is improved. Even if an error occurs, there is no need for precise drafting of the recess and foot, which greatly improves productivity, and there is no variation in the adhesion strength between the foot of the electrode plate group and the recess, ensuring stable adhesion. maintain the condition.
上述したように、本考案は実用的価値甚だ大なるもので
ある。As mentioned above, the present invention has great practical value.
