をのべる。Conventional Technologies and Their Problems Various structures and manufacturing methods have been proposed for the terminals of lead-acid batteries. Among them, an example of the terminals often seen in sealed lead-acid batteries, for which the demand for lead-acid batteries has been increasing rapidly in recent years, has been proposed. This is shown in FIG. 3, and the prior art and its problems will be described based on this figure.

ｌＯでシールする。In the figure, a strug 3 is formed by welding the tips of the ears 1a of a plurality of polar plates 1 of the same polarity, and a name or lead alloy is cast on the top surface of the strap that will form the battery terminal at the same time as welding. Connect the pole pillars 5 made of After the welded electrode plates are placed in a battery case 6 and the connections between the cells are made, the battery cover 7 is covered and bonded to the battery case, and the pole pole is exposed to the outside through a through hole provided in the battery case cover.

があり、また、櫛型溶接治具を用いて溶接を行う場合に
は、治具は厚さ不足となって耐久性も不十分であった。The electrode plate ears can be welded by supporting the ears 1a with a comb-shaped welding jig at intervals, and by covering the ears with a burner while supplementing lead or lead alloy, or by melting the ears in a heated mold. A widely used method is to pour lead or lead alloy into the electrode plates at the same time. There is a risk of deformation or shrinkage, and when welding is performed using a comb-shaped welding jig, the jig is insufficiently thick and has insufficient durability.

If the pole length is too low, there is a risk of a short circuit between the pole plates, and if the pole pole is shortened, there is a risk that the electrolyte will leak from the terminals because the seal length provided by the filler will not be sufficient.
