である。Conventional technology and its problems Lead-acid batteries generally lead the electricity stored in the electrode plate to a terminal provided on the outer surface of the battery through a grid made of lead alloy, a strap, and a pole, and take it out to the outside through this terminal. Target.

いる。There are two types of grids, one for positive electrodes and the other for negative electrodes, and batteries in which one or both of them are made of antimony-free lead alloy (hereinafter referred to as antimony-free alloy) have been put into practical use. At this time, an antimony lead alloy (hereinafter referred to as an antimony alloy), which is generally excellent in strength, is used for the strap, the pole, and the terminal, but it has been found to have the following problems.

短くなるケースがしばしば生じる。That is, if current flows through the welded joint of antimony alloy and antimony-free alloy, and if this joint gets wet with sulfuric acid (electrolyte), one of the lead alloys will be excessively corroded, and the grid or strap Often, one of them is corroded, a joint is disengaged, an electric current is defective, etc., and the life of the battery is often shortened as compared with a lead storage battery using only an antimony alloy grid.

くるため、硫酸により濡らされ、過度の腐食を生ずる。This will be specifically described with reference to FIGS. 3 and 4. In general, the terminal portion is formed by penetrating a lead bushing 2 embedded in a lid 3 through a pole column 1 standing upright on a strap of a plate group and welding the tops of the pole columns. If the grid is a Funtimon free alloy, the straps and poles 1 can be antimony free alloys to avoid excessive corrosion of these welds. However, since the terminal portion is used for connection with the outside, bending, twisting, crushing and the like are likely to occur, and the lead bushing 2 is required to have strength equivalent to that of the antimony alloy.
If the entire lead bushing 2 is made of antimony alloy, the pole 1
Since the sulfuric acid in the battery is transmitted to the surface of the pole 1 at the welded portion with, it is wetted by sulfuric acid and causes excessive corrosion.

ことを特徴とするものである。Means for Solving the Problems The present invention uses an antimony alloy for a terminal that requires the highest strength, and prevents the joint between the antimony-free alloy and the antimony alloy from being wetted by sulfuric acid. The straps and poles connected to the grid were made of antimony-free alloy, and the lead bushing embedded in the lid was made of antimony-alloy and the inner surface and top were made of antimony-free alloy to form the terminals connected to them. It is characterized by that.
実 施 例 以下、本発明の一実施例を第１図、第２図について説明
