【考案の詳細な説明】
本考案は、モノブロツク蓄電池の各セルを電気
接続する蓄電池セル間接続装置の改良に関するも
のである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a storage battery cell connection device for electrically connecting each cell of a monoblock storage battery.
従来蓄電池のセル間接続装置として、開口を有
する隔壁を挟んで対向する凸形の雄中間極柱と、
凹形の雌中間極柱とを抵抗溶接電極で通電加圧
し、両者を一体に溶接することが行なわれている
が、該溶接部の電気的、機械的特性を良好にし、
しかも隣接セル間の完全な気密を保持することは
困難であつた。 Conventionally, as an intercell connection device of a storage battery, a convex male intermediate pole pole facing each other across a partition wall having an opening,
It is common practice to weld the two together by applying current and pressure to the concave female intermediate pole using a resistance welding electrode.
Moreover, it has been difficult to maintain complete airtightness between adjacent cells.
特に近年蓄電池の製造工程の自動化により、電
槽内への極板群挿入を容易にする為、雄中間極柱
の突起の長さを短くする為気密不良が顕著に表わ
れた。 Particularly in recent years, with the automation of the storage battery manufacturing process, the length of the protrusion on the male intermediate pole pillar has been shortened in order to facilitate the insertion of the electrode plate group into the battery case, resulting in poor airtightness.
この欠点を防止する為には加圧力を増加させた
り、溶接時間を長くすることが考えられるが、加
圧力を増加させたり溶接時間を長くすることは中
間極柱や電槽に過大なストレスを生じさせ、機械
的強度を低下させるため好ましくなかつた。 In order to prevent this drawback, increasing the pressurizing force or lengthening the welding time may be considered, but increasing the pressurizing force or lengthening the welding time will place excessive stress on the intermediate pole and the battery case. This was not preferable because it caused the formation of abrasive particles and reduced the mechanical strength.
本願考案は上記に鑑みなされたもので、隣接セ

置を提供することを目的とする。 The invention of the present application has been made in view of the above, and aims to provide an intercell connection device for a storage battery that maintains good airtightness between adjacent cells and also has good electrical and mechanical properties of the intermediate pole-column welded portion.

る。 In order to weld these male and female intermediate pole columns 3 and 8 to each other, the protrusions 7 of the male intermediate pole columns 3 and 8 are inserted into the opening 2 of the partition wall 1 from one side of the partition wall 1, and the female intermediate poles are placed in the other side. The pillar 8 is placed with the protrusion 7 inserted into its recess 10, and a resistance welding electrode is brought into contact with each intermediate pole pillar 3 and 8, and energized with a predetermined current and pressure. As a result, the male and female intermediate pole columns 3 and 8 are integrally welded to each other, and the outer periphery of the protrusion 7 of the male intermediate pole column 3 and the female intermediate pole column 8 are welded together.
The outer periphery of the recess 10 is brought into close contact with the partition wall 1. As shown in FIG. 1, the cell-to-cell connection device constructed in this way has a partition between the base tapered large-diameter portion 6 of the protrusion 7 of the male intermediate pole 3 and the edge of the recess 10 of the female intermediate pole 8. 1 from both sides to keep the area airtight. That is, although the partition wall 1 is deformed toward the female intermediate pole due to the tapered base portion 6, the deformation is prevented by the edge of the recess 10, and this portion can be kept airtight. Further, since the tip of the protrusion 7 and the inner wall of the recess 10 are melted, the inside of the recess 10 is filled with molten lead, so that the weld area of the weld increases, the electrical characteristics become better, and the mechanical strength becomes stronger.
