Concatenated. These straps 6°8 connect the intercell connections 9.1
It has 0. A method of integrating the plurality of electrode plates 1.2 and the strap 6.8 includes placing each ear portion 1A in a molten lead alloy for strap formation in a mold for forming a strap.
, 2A is inserted, and the strap 6.8 is integrated with each ear portion IA, 2A during molding of the strap 6.8, which is a so-called cast-on strap method.

３内に挿入されるように極板群４を降下させる。Figures 5(A)' and 5(B) illustrate this cast-on strap method. In the figure, reference numeral 11 denotes a mold for forming a strap, and the temperature of the mold 11 is normally adjusted appropriately using an electric heater (not shown) or the like. 12 and 13 are a pair of recesses each provided in the mold 11, each recess 12 is for forming an inter-cell connection part 9.10, and each recess 13 is for forming a strut and a tab 6.8. It is something to be molded. When the strap-forming lead alloy groove 114 is injected into each recess 12 and each recess 13 of the mold 11 formed in this way, the strap-forming lead alloy molten metal 14 is cooled and immediately begins to drop in temperature; Before solidifying, the ears IA and 2A of the electrode plate group 4 are inserted into the molten metal 14. For this purpose, the electrode plate group 4 is placed upside down on the mold 11 with each ear portion IA, 2A facing downward.
Separately, a lead alloy groove 114 for forming a strap is formed in the mold 11.
After pouring the molten metal, the ears IA and 2A are inserted into each recess 1 at an appropriate timing.
The electrode plate group 4 is lowered so that it is inserted into the electrode plate group 3.

4 solidification forms intercell connections 9.10 and straps 6.
8 is formed, and at the same time the strap 6.8 and each plate 1,
The two ears IA and 2A are mechanically and electrically integrated.

。In this way, when the strap and each ear are integrated, the amount of molten lead alloy for forming the strap poured into the mold for forming the strap is approximately 10 IdlPi! The temperature is about 510°C, and even though a plurality of ears are inserted into the molten metal, the heat dissipation effect of each electrode plate 1 and 2 prevents the I
I rapidly lowers its temperature, and the molten metal in the mold begins to solidify in about 2 seconds, and solidification is completed in about 10 to 15 seconds. As described above, since the time for the WIs to coagulate is extremely short, and there is an oxide film etc. on the surface of each ear, it is difficult to weld each ear to the strap well.

It is 0±10°C. The temperature of the strap molding mold is 15
Melting the above lead alloy for forming the strap at 0±3℃? Each lug of the electrode plate group is inserted at a timing such that the tip of each lug reaches the molten metal surface 1.3 seconds after pouring 911d into the mold. Incidentally, a 5% aqueous solution of diethylamine hydrochloride was used as the flux, and the insertion speed of the ears (lowering speed of the electrode plate) was 24.3 shoes/sec. The joints between the strap and each ear obtained by the method of the present invention obtained as described above and the joints obtained by the conventional method were tested for 100 samples. In addition to checking the formation of fillets, the cross section of the joint was observed under a microscope to determine the occurrence of poor wetting of each ear of the lead alloy mIi for strap formation and the occurrence of plowholes (targeted shoes with a diameter of 0.1 or more). Examined. As can be seen from the table below, it can be seen from this result that the effect of brushing according to the method of the present invention is very large.

By brushing each ear, the brush grooves formed on the surface of each ear can match the direction in which the wetted area of the molten lead alloy for forming the strap spreads, increasing the wetting speed. When inserted into the lead alloy molten metal for forming each ear, each ear is wetted with the molten metal up to above the surface of the melt field, and a fillet is formed rising from the strap side at the base of each ear with respect to the strap. The cross-sectional area of the connecting portion between each ear portion and the strap can be widened and the straps can be firmly connected, so that each electrode plate can be firmly connected with the strap.
