WIRE CONNECTION STRUCTURE AND METHOD

摘要

PROBLEM TO BE SOLVED: To improve workability when attaching a high-voltage wire.SOLUTION: A wire connection structure includes: a plurality of battery groups 5 each formed by series-connecting a plurality of batteries 3 provided so as to be spaced from each other; and total electrodes 19 and 21 of the adjacent battery groups connected to each other using a high-voltage wire 9 having crimp terminals 31 and 33 at both ends thereof. The high-voltage wire is connected so that the crimp terminal is fastened by a nut 37 to a conductor 23 of a resin bus bar module 7, the conductor 23 being connected to the total electrode. The bus bar module includes two ribs 45 and 47 (53 and 55) limiting co-rotation of the crimp terminal being fastened, at positions sandwiching the crimp terminal. An interval of the two ribs is set so that a difference between the interval and a width of a straight portion of the crimp terminal connected to one total electrode of the adjacent battery electrodes is set to a first interval dimension L3 and a difference between the interval and a width of a straight portion of the crimp terminal connected to the other total electrode is set to a second interval dimension L6 greater than the first interval dimension.
