本発明は蓄電池、特に密閉形蓄電池に係るものであり、
震動や衝撃に対する耐性が良く信頼性の高い蓄電池を提
供することを目的とするものである。[Detailed Description of the Invention] The present invention relates to a storage battery, particularly a sealed storage battery,
The purpose is to provide a highly reliable storage battery that has good resistance to vibrations and shocks.
電解液をゲル化あるいは多孔体にしみ込ませてその流動
を規制した密閉形蓄電池は、モノブロック電槽の隔壁貫
通口の封口が不完全であっても自己放電が極めて少ない
ことから、隔壁貫通口に間隙を残してセル間接続導体を
挿通し、該蓄電池の構造および製造の簡略化を計る提案
が既になされている。Sealed storage batteries, in which the electrolyte is gelled or impregnated into a porous material to regulate its flow, have extremely low self-discharge even if the partition wall penetration hole of a monoblock battery case is incompletely sealed. A proposal has already been made to simplify the structure and manufacture of the storage battery by leaving a gap between the cells and inserting the intercell connection conductor.
しかしながらこの種のものでは震動や衝撃に対して電池
要素が動揺すると云う欠点があり、このため電槽母種と
電槽蓋とで隔壁貫通口を形成し、この電槽母種側あるい

することが試みられた。However, this type of battery has the disadvantage that the battery element sways due to vibrations or shocks.For this reason, a partition wall penetration hole is formed between the battery case base and the battery case cover, and the battery element is moved from the battery case base side or the battery case. Attempts have been made to provide a protrusion on the lid side to press the top surface of the inter-cell connection conductor.
ところがこの構造のものではセル間接続導体の高さなど
の不均一により、該セル間接続導体を突起にて平均した
力で押圧することができず、震動や衝撃に対しての信頼
性が極めて低かった。However, with this structure, due to the unevenness of the height of the inter-cell connecting conductor, the protrusions cannot press the inter-cell connecting conductor with an even force, making it extremely unreliable against vibrations and shocks. It was low.
一方ストラップの定着方法として電槽母種接合部と電槽

ップの上面を押圧する方法が提案されている。On the other hand, as a method for fixing the strap, the battery case base joint and the battery case lid joint are heated, and the tip of the fixing piece provided downward inward to the battery case lid is heated and softened, and then the battery case base is joined. A method has been proposed in which the strap and the battery case lid joint are overlapped and crimped, and at the same time the upper surface of the strap is pressed with a fixing piece.
しかしこの方法では加熱軟化せしめた固定片の先端がス
トラップとの当接時において該ストラップに熱を奪われ
固化すると云う欠点があり、そのための加熱手段として
熱板の固定片加熱部分を特に高温にするなどの特殊な手
段を必要とする欠点があった。However, this method has the disadvantage that when the tip of the fixing piece that has been softened by heating comes into contact with the strap, the strap absorbs heat and hardens.As a heating means for this purpose, the heated part of the fixing piece of the hot plate is heated to a particularly high temperature. It had the disadvantage of requiring special measures such as

続導体６が定着される。Further, a hanging pillar 15 is formed on the inner surface of the battery case lid 7.
The fixing member joint 16 at the tip of the hanging pillar 15 is melted at the same time as the battery case base joint 8 and the battery case lid joint 9 are melted, and the battery case base joint 8 and the battery case lid joint 9 are melted together. At the time of crimping, the battery case lid joint 9 is attached to the fixing member joint 1 on the upper surface of the fixing member 14.
