本発明は、極柱の形状を改良した蓄電池に関す
る。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a storage battery with improved pole column shapes.
一般に蓄電池は、第１図に示すように電解液１
を入れた電解槽（図示せず）の上部を蓋板２で施
蓋し、この蓋板２の裏面に極柱３を取付けてい

４と接続し、下部を電解液１内に浸漬して図示し
ない極板群に接続している。 Generally, a storage battery has an electrolyte 1 as shown in Figure 1.
The upper part of an electrolytic cell (not shown) containing the electrolytic cell is covered with a cover plate 2, and a pole post 3 is attached to the back surface of this cover plate 2. The pole pillar 3 has its upper end connected to a terminal 4 on the surface of the cover plate 2, and its lower end immersed in the electrolytic solution 1 and connected to a group of electrode plates (not shown).
しかして上記極柱３は、電解液１と接触し、あ

電解液のアツパレベルＵとロウアレベルＬとの間
において腐食が著しく、この腐食によるいわゆる
「やせ」が原因となつて蓄電池の寿命が低下する
ことが知られている。 However, the pole column 3 is easily corroded due to contact with the electrolytic solution 1 or adhesion of acid mist. It is known that corrosion is particularly severe between the upper level U and the lower level L of the electrolytic solution, and the so-called "thinning" caused by this corrosion shortens the life of the storage battery.
このことから従来は、この対策として極柱全体
を、必要とする容量以上に太くして、腐食による
「やせ」が生じても極柱３の容量を保持できるよ

柱自体が重い（通常鉛で形成される）ことも相俟
つて蓄電池にしめる極柱３の占める重量割合が大
きくなつてしまう。とくに近時自動車用等の用途
が開発されつつあることから、蓄電池の重量がか
さむことは重要な問題である。 Conventionally, as a countermeasure against this problem, the entire pole pole is made thicker than the required capacity so that the capacity of the pole pole 3 can be maintained even if "thinness" occurs due to corrosion. However, if the entire pole pole is made thicker, the pole pole itself is heavy (usually made of lead), and the weight ratio of the pole pole 3 used in the storage battery increases. In particular, as applications for automobiles and the like are being developed in recent years, the increased weight of storage batteries is an important problem.
本発明は上記事情に鑑み、蓄電池の軽量化を図
るべくなされたもので、その目的とするところは
極性全体を太くせず、とくに腐食の激しい電解液
面レベルに対応する個所のみを太くすることによ

きるとともに極柱を軽量とすることができる蓄電
池を得んとするものである。 In view of the above circumstances, the present invention was made in order to reduce the weight of a storage battery, and its purpose is not to make the entire polarity thicker, but to make it thicker only at the part corresponding to the electrolyte level where corrosion is particularly severe. Therefore, it is an object of the present invention to obtain a storage battery that can maintain the required capacity of the pole column even after long-term use, and can also make the pole column lightweight.

より太径にしたことを特徴とするものである。 That is, the present invention has a hollow cylinder that is suspended from the back surface of the battery case lid and that surrounds a pole pole that is attached to the back surface of the battery case lid, and whose lower end reaches the lower level (L) of the specified electrolyte level of the storage battery. In addition, the electrode column is characterized in that the electrolyte liquid level level and the vicinity thereof are made larger in diameter than other portions.
以下本発明の実施例を図面にもとづいて説明す

ピレン等の耐食性材料で形成され、下部を電解液
１１内に浸漬して、下端開口部の位置を電解液１
１のロウアレベルＬよりも若干下方としている。 FIG. 2 is an enlarged cross-sectional view of the main parts of a lead-acid battery. This storage battery has a lid plate 12 placed on top of a container (not shown) containing an electrolyte 11.
A cylindrical body 13 and a pole pillar 14 are attached to the back surface of 2. This cylindrical body 13 is made of a corrosion-resistant material such as polypropylene, which is the same material as the cover plate 12, and its lower part is immersed in the electrolytic solution 11 to adjust the position of the lower end opening into the electrolytic solution 11.
It is set slightly lower than the lower level L of No. 1.

場合極柱１４の上部の外径d1は、必要とする極柱
容量にみあつた外径である。また極柱１４の下部
の外径d3は従来のものと略同程度の外径である。 On the other hand, the pole post 14 is located at the center of the cylindrical body 13, and its upper end is connected to the terminal 15 on the surface of the cover plate 12, and its lower end is immersed in the electrolytic solution 11 and connected to a group of pole plates (not shown). ing. This pole column 14 has an outer diameter of d 1 at the upper part, d 2 at the portion corresponding to the lower end of the cylinder 13 and its vicinity, and d 3 at the lower part immersed in the electrolytic solution 11. 1 < d 3 < d 2 , and the outer diameter d 2 of the portion corresponding to the lower end of the cylinder 13 and its vicinity
The outer diameter of only one part is made thicker than the other parts. In this case, the outer diameter d 1 of the upper part of the pole column 14 is an outer diameter that meets the required pole column capacity. Further, the outer diameter d 3 of the lower part of the pole pillar 14 is approximately the same as that of the conventional one.
しかしてこの構成によれば、使用時に電解液１
１の液面レベルがアツパレベルＵとロウアレベル
Ｌとの間で変化しても、筒体１３内においては、
空気の逃げ場がないために筒体１３内における電
解液液面レベルは、筒体１３下端において略一定
に保持される。 However, according to the configuration of the lever, when using the electrolyte 1
Even if the liquid level of 1 changes between upper level U and lower level L, inside the cylinder 13,
Since there is no place for air to escape, the level of the electrolyte within the cylinder 13 is maintained at a substantially constant level at the lower end of the cylinder 13.
この状態において、極柱１４は電解液面レベル
において主に腐食されるが、この個所を太くして
いるために腐食が生じても問題がない。 In this state, the pole pillar 14 is mainly corroded at the electrolyte level, but since this part is made thicker, there is no problem even if corrosion occurs.
また極柱１４は、筒体１３で保護されているた
め、筒体１３外からの酸霧が極柱１４上部に付着
することがなく、ここが腐食されるおそれがな
い。このため、この個所の極柱の太さを、腐食を
考慮せずに容量に見合つた径まで細くできる。 Further, since the pole column 14 is protected by the cylinder 13, acid mist from outside the cylinder 13 will not adhere to the upper part of the pole column 14, and there is no risk of corrosion there. Therefore, the thickness of the pole column at this location can be reduced to a diameter commensurate with the capacity without considering corrosion.
なお極柱の電解液面レベル及びその近傍に対応
する個所の断面形状は、第２図のものに限らず第
３図に示すように腐食のされやすさに応じて中央
が膨出した形状となすようにしてもよい。 The cross-sectional shape of the pole pillar at the electrolyte level and its vicinity is not limited to the one shown in Figure 2, but can also be shaped with a bulge in the center depending on the susceptibility to corrosion, as shown in Figure 3. You may do as you like.
このように、腐食の大きな個所のみを太径とし
て他の個所を容量に見合つた径まで細くしたので
極柱の重量を軽減でき、その軽減量は従来のもの
に比べて例えば10％程度となる。 In this way, by making the diameter of the heavily corroded parts larger and reducing the diameter of the other parts to a size that matches the capacity, the weight of the pole can be reduced, and the amount of reduction is, for example, about 10% compared to conventional poles. .

減量しうる等の効果を奏するものである。 As described above, according to the present invention, the cylindrical body surrounding the pole column is made to hang down so as to reach the lower level of the specified electrolyte level, and the electrolyte level of the pole column and its neighboring parts are made thicker than other parts. Since the diameter is made smaller, corrosion of the pole pole can be prevented and the weight of the pole pole can be significantly reduced.
