密閉型鉛蓄電池およびその製造法
Document Type and Number:
Japanese Patent JP3601248
Kind Code:
B2
Abstract:
An enclosed storage battery having an excellent closed tightness and reliability is obtained. An annular bump (8) is formed integrally with the upper periphery of the penetration hole of a lead-alloy bushing (3) buried in the top of the lid for covering the jar. The leading end of the pole (5) passing through the penetration hole of the bushing is inserted into the lower part of the annular bump. A recess (11) is formed on the top of the leading end of the pole so as to be easier to melt the upper portion of the pole, and by welding with the inner wall of the penetration hole of the bushing, the annular bump is later melted, and the bushing penetration hole is filled up with the fused lead.
