形成する方法である。Conventional technology In the electrode group of conventional lead-acid batteries, there is a part called a strap, which integrates a large number of electrode plates in an electrolytic chamber and electrically connects them to adjacent electrolytic chambers. do. Methods for manufacturing this part include one-burner type and cast-on type. The one-burner type is a method in which the straps are formed by supplying separately prepared lead, called added lead, while melting the edges of the electrode plate.The cast-on method is a method in which the straps are formed by supplying separately prepared lead, called added lead, while melting the edges of the electrode plate. This method involves dipping the edges of the electrode plate to form a strap.
このような製造方法の相違はあるが、従来の極板群のス
トラップはいずれも鉛部材のみで構成されていた。Despite these differences in manufacturing methods, the straps of conventional electrode plate groups have all been made of lead material only.

By removing the welded portion 5, a covering portion 9 is formed in which the strap portion 1, the electrode plate ear portion 3, and the polypropylene resin are molded, as shown in FIG. FIGS. 4 and 5 show cross sections of the strap part 1 and the plate ear part 3 which are soldered with polypropylene resin. In order to protect the plate ear part 3 from external forces, It is preferable to mold the strap part l so as to cover at least two fins from the lower part of the electrode plate ear part 3.

It also has great industrial value as it can prevent breakage due to stress applied to the connection between the strap part and the electrode plate ear because it is fixed with polypropylene resin around the connection part. It is something.
