部分は常に濡れている状態であった。2. Description of the Related Art A terminal portion of a conventional sealed lead-acid battery has a configuration shown in a partial sectional view of FIG. In the figure, 1 is a middle lid, 2 is a battery case,
Reference numeral 3 denotes a pole, which penetrates through the opening of the middle lid 1 and closes the through clearance with a rubber packing 5;
Was connected to the head of the pole 3 by solder 11, and the adhesive pot provided on the middle lid 1 with the adhesive 4 was sealed to form a terminal portion of the sealed lead-acid battery. Further, the electrolyte solution 8 inside the lead storage battery creeped to the vicinity of the rubber packing of the pole 3, and this portion was always in a wet state.

池の外部へリークするという取扱上の安全性および電池
特性の重大な欠陥につながる問題があった。However, when pushing in the receptacle, the upper surface 4 'of the adhesive is
And the pole 3 is also stressed, so that the upper surface 4 'of the adhesive is
Cracks may occur from the portion where the metal terminal plate 6 touches the metal, the boundary surface between the adhesive 4 and the terminal plate 6, and the adhesive 4 and the pole 3
In some cases, a small gap was generated at the boundary surface between the substrate and the substrate.
At this time, there has been a problem that the electrolyte 8 goes up a minute gap and leaks to the outside of the lead storage battery, which leads to serious defects in handling safety and battery characteristics.
課題を解決するための手段 極柱に端子の一端が接続され、前記極柱と前記端子の
接続部が中蓋に設けた接着剤ポット内に収納されて接着

とも１回折り曲げられたものである。Means for solving the problem One end of the terminal is connected to the pole, and the connection portion between the pole and the terminal is housed in an adhesive pot provided in the inner lid and sealed with an adhesive, and In a lead-acid battery in which the other end of the terminal protrudes from the adhesive, the protruding portion of the terminal is taken out from the upper surface of the adhesive, is bent downward from the upper surface of the adhesive, and is bent at least once below the upper surface of the adhesive. It was done.
作用 前記の構成によれば、端子板にレセプタクルをしまり
かん合させるよう押し込む力を加えても、接着剤上面よ
り下方に設けた端子板の屈曲点でその応力を吸収できる
ため、接着剤に亀裂を生じることはなく、電解液が鉛蓄
電池の外部へリークする問題を防ぐことができる。Operation According to the above configuration, even if a force is applied to the terminal plate so as to tightly fit the receptacle, the stress can be absorbed at the bending point of the terminal plate provided below the upper surface of the adhesive. And the problem that the electrolyte leaks out of the lead storage battery can be prevented.
実施例 以下、本発明の実施例について第１図および第２図を
参照して説明する。Embodiment Hereinafter, an embodiment of the present invention will be described with reference to FIG. 1 and FIG.

る。In FIG. 1, the head of the pole 3 and the base of the terminal plate 7 are connected by solder 11, and the adhesive pot of the middle lid 1 is sealed with an adhesive. The terminal plate 7 is taken out from the upper surface 4 'of the adhesive, and is bent three times at a substantially right angle three times. Further, the adhesive is positioned in the groove 12 of the middle lid 1 provided beforehand in a state of being bent two times below the upper surface 4 'of the adhesive. In this configuration, when the used equipment connection receptacle 9 shown in FIG. 2 is tightly fitted in the direction of the arrow of the terminal plate 7 and pushed in, the adhesive upper surface 4 ′ is taken out from the adhesive upper surface 4 ′. Bending deformation occurs with the lower bending point 10 'as a fulcrum. At this time, since the fulcrum 10 'is located below the adhesive upper surface 4', the stress applied to the terminal plate 7 is not directly applied to the adhesive upper surface 4 'or the solder 11 portion. Therefore, there is no fear that a small clearance is generated at the boundary between the adhesive 4 and the terminal plate 7 and at the boundary between the adhesive 4 and the pole 3.
