Description

図３に示す電極板２を用いた場合であっても、図１に示す場合と同様に電極板２と保持部材３とを接続することができる。突き合わせた電極板２と電極板保持部材４の両主面を２枚の導電接続部材６で挟み込み、電極板２の溝部７ａと２枚の導電接続部材６、及び電極板保持部材４と２枚の導電接続部材６のそれぞれにボルト５を貫通させ、ボルト５と図示しないナットとを締結する。２枚の導電接続部材６で電極板２を挟み込むことによって、溝状に形成した溝部７ａであっても電極板保持部材４から電極板２が落下せずに取り付けることができる。 Even when the electrode plate 2 shown in FIG. 3 is used, the electrode plate 2 and the holding member 3 can be connected as in the case shown in FIG. Both main surfaces of the butted electrode plate 2 and electrode plate holding member 4 are sandwiched between two conductive connection members 6, and the groove 7a of the electrode plate 2, the two conductive connection members 6, and the electrode plate holding member 4 and two sheets. Bolts 5 are passed through each of the conductive connecting members 6 and the bolts 5 and nuts (not shown) are fastened. By sandwiching the electrode plate 2 between the two conductive connection members 6, the electrode plate 2 can be attached without dropping from the electrode plate holding member 4 even in the groove portion 7 a formed in a groove shape.

溝部７ａが形成された電極板２は、鋳型１５に溝部７ａを形成する凸部１５ｂが形成されているため、鋳型１５内で低融点金属又は低融点合金を溶融させ、冷却固化させる、又は溶融した低融点金属又は低融点合金を流し込み、金属を冷却固化させるだけで製造することができる。これにより、溝部７ａが形成された電極板２は、貫通孔７が形成された電極板２よりも容易に且つ効率的に製造することができる。 In the electrode plate 2 in which the groove portion 7a is formed, since the convex portion 15b that forms the groove portion 7a is formed in the mold 15, the low melting point metal or the low melting point alloy is melted in the mold 15 and cooled or solidified. The low-melting-point metal or low-melting-point alloy can be poured and the metal can be cooled and solidified. Thereby, the electrode plate 2 in which the groove part 7a was formed can be manufactured more easily and efficiently than the electrode plate 2 in which the through-hole 7 was formed.

溝部７ａを形成した電極板２を用いる場合は、先に電極板保持部材４及び導電接続部材６の貫通孔８、９にボルト５を貫通させて、ボルト５とナットを緩めに締結しておき、その後、電極板２の溝部７ａにボルト５が嵌るように差し込んだ後にボルト５とナットをしっかりと締め付けて、電極板２と保持部材３とを一体化した陽極１を得ても良い。 When using the electrode plate 2 in which the groove portion 7a is formed, the bolt 5 is first passed through the through holes 8 and 9 of the electrode plate holding member 4 and the conductive connection member 6, and the bolt 5 and the nut are tightened loosely. Then, after inserting the bolt 5 into the groove portion 7a of the electrode plate 2, the bolt 5 and the nut may be firmly tightened to obtain the anode 1 in which the electrode plate 2 and the holding member 3 are integrated.
