Title:
ANGULAR SEALED BATTERY
Document Type and Number:
Japanese Patent JP3149010
Kind Code:
B2
Abstract:

PURPOSE: To simplify a manufacturing process, and reduce the coating failure of a sheathing tube, by providing a projection, abutting on the outer surface of a cap, on the inner surface of a hole formed so that a positive electrode terminal cap can be fittedly inserted by a small gap in an insulating plate on a sealing plate.
CONSTITUTION: A positive electrode terminal cap 7 is liquid-tightly mounted on the middle hole 3a of a sealing plate 3, welded to the opening end 2a of an angular case 2, to be deposited on the upper end of an anode rivet 5. The thickness of an insulating plate 10 is formed slightly lower than the height of the cap 7, and an angular hole 10a slightly larger than the cap 7 is provided on the middle to form protruded projections 10a and 10e on the middle in the vicinity of the upper opening ends of the inner surfaces 10b and 10c facing with each other. The insulating plate 10 is placed on the sealing plate 3, and the cap 7 is fittedly inserted into the hole 10a to be coated integrally with the case 2 by a heat shrinkable sheathing resin tube 9. At that time, since the facing side surfaces 7b and 7c of the cap 7 are made to abut with each other by slight pressing force, thereby preventing the falling or displacement of the insulating plate 10 from the sealing plate 3.
