産業上の利用分野
本発明は、鉛蓄電池に関するもので、特に密閉
形鉛蓄電池において端子極柱と電そうを覆うふた
との接着構造および引き出し用端子を改良して耐
漏液性に優れた鉛蓄電池に提供するものである。DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to lead-acid batteries, and in particular improves leakage resistance by improving the adhesive structure between the terminal pole and the lid covering the electric housing and the draw-out terminal in a sealed lead-acid battery. This is provided for lead-acid batteries with excellent liquid properties.
従来の技術
鉛蓄電池は電解液に希硫酸を用いているため、
特に電解液の電池外部へのリークは、電池自体に
害があるばかりでなく、電池を使用している機器
をもいためるためもつともきらう問題である。Conventional technology Lead-acid batteries use dilute sulfuric acid as the electrolyte, so
In particular, leakage of electrolyte to the outside of the battery is a problem that should be avoided because it not only harms the battery itself, but also damages equipment using the battery.
このようなリーク現象は主に(1)電そうとふたと
の間、(2)電池の端子極柱の周囲および、(3)モノブ
ロツク電池の場合セル間に起きていた。従つてこ
のリーク現象を防止することは鉛蓄電池の従来か
らの課題であつたが、容易な方法でかつ確実な防
止方法がみつかつていなかつた。 This type of leakage phenomenon mainly occurred (1) between the battery pack and the lid, (2) around the terminal poles of the battery, and (3) in the case of monoblock batteries, between the cells. Therefore, preventing this leakage phenomenon has been a conventional problem for lead-acid batteries, but an easy and reliable method for preventing it has not yet been found.
これまでの端子極柱のふたへの接着方法につい
て、その具体例を次に説明する。 A specific example of the conventional method of adhering the terminal pole to the lid will be described below.
まず、ふたの裏面に形成したセル間を接続する
Ｕ字状接続体が埋没するくぼみ部分および電そう

を半田付けする。この後接着剤をふたの表側に設
けたくぼみに充填する工程を経て、接着剤を固化
させることにより端子極柱とふたとを接着する。 First, there is a process of filling adhesive into the recessed part formed on the back side of the lid where the U-shaped connector connecting the cells is embedded and the annular recessed part of the outer periphery where the electric cell and the lid are bonded. There is a process of gluing the lid upside down with the electrodes already inserted into the lid with the back side facing upwards. At this time, the terminal pole post is not buried in the adhesive, but is projected to the outside through the pole post hole provided in the lid. Next, the adhesive is solidified, and the battery is returned to its normal position. After that, to prevent the adhesive for fixing the terminal pole pole to the lid from falling onto the electrode plate group on the cell chamber side from the pole pole hole, cover the terminal pole with rubber packing, so that the tip of the pole pole and the side shape are approximately L. Solder the letter-shaped Faston tab terminal. Thereafter, a step is performed in which the recesses provided on the front side of the lid are filled with adhesive, and the adhesive is solidified to bond the terminal pole pillar and the lid.

子とを挿入し、１回の接着作業でこれらの固定を
図ることが提案された。 However, in this battery manufacturing method, the work of gluing the terminal pole to the lid must be done in two stages: the U-shaped connector part that connects the cells, and the terminal pole part, which increases the number of man-hours. In addition, it takes a long time for the adhesive to solidify, so it has the disadvantage that it takes too much time to complete the battery. As an improvement, it was proposed to insert the inter-cell connector and the Faston tab terminal, which has already been connected to the pole, into the adhesive filled on the back of the lid, and to fix them in a single adhesive operation.

いた。Problems to be Solved by the Invention Although this has made it possible to perform bonding work only once, it also requires a space to accommodate the Faston tab terminal, which does not contribute to battery performance in any way, resulting in a large so-called dead space. This has been a problem when trying to make batteries smaller, lighter, and more efficient.

隙を設けたものである。Means for Solving the Problem In order to solve this problem, the present invention reduces the shape of the terminal by making it substantially U-shaped in plan view, and also improves the structure of the terminal and the lead-out part. A small gap is provided between the housing recess and the adhesive so that it does not rise up due to capillary action and flow out to the outside.
