Title:
LEAD ACID BATTERY
Document Type and Number:
Japanese Patent JP3221164
Kind Code:
B2
Abstract:
PURPOSE: To prevent improper connection of a pole by positioning the upper surface of a staircase-shaped step differenced part, provided in the pole of passing through a pole through hole to protrude in the peripheral direction, in the upper from the surface of a bonding agent with which the periphery of the pole is filled, so as to impede the bonding agent from rising on a side surface of the pole.
CONSTITUTION: In a bonding agent filling recessed part 4 of surrounding a pole through hole 3 of a cover 2, the periphery of a pole 1, liquid-tightly sealed with an 0 ring 5 by passing through the hole 3, is filled with epoxy resin as a sealing bonding agent 6. In a side surface of the pole 1, an annular protrusion part 10 protruded about 2mm in the peripheral direction is provided so that the upper surface is positioned in the upper from a surface of the bonding agent 7 to sink the part 10 about 4 to 6mm in the bonding agent 6. A bolt insertion hole 9 of the pole 1 is provided in 10mm upward from the upper surface of the protrusion part 10, and accordingly, a contact part 11 of the surface of the bonding agent 6 with the pole 1 is placed along an upper surface peripheral edge part of the protrusion part 10. Thus by preventing the bonding agent 6 from rising to the hole 9, improper contact in a terminal part is prevented.
