Title:
BUSHING FOR FORMING TERMINAL FOR METAL ION ELECTROCHEMICAL ACCUMULATOR BATTERY, AND RELEVANT ACCUMULATOR BATTERY
Document Type and Number:
Japanese Patent JP2019110122
Kind Code:
A
Abstract:
To provide a bushing for forming the terminal of a metal ion electrochemical accumulator battery, in which electrical uniformity and thermal uniformity of the accumulator battery in a battery pack are improved.SOLUTION: A bushing is a conductive male component (5) formed through a hole opening on one and the other sides of a wall (9) of a case, and having a passage on the inside, where the passage is intended to circulate cooling fluid circulated along the ordinate of an accumulator battery. The passage includes the male component (5) opening toward the outside of the accumulator battery, a conductive female component (50) adjusted to be tightened around a portion of the male component on the outside of the accumulator battery, an abutment part where two electrical insulation washers (48, 49) abut on the faces of the wall simultaneously while compressing, and a guide part projecting for the abutment part and coming into contact with the edge of the hole. The washer (48) abuts on the female component while compressing, and the washer (49) abuts on the male component while compressing.SELECTED DRAWING: Figure 35
