Patent ID: 7607924

Claim:
An electronic control unit comprising a circuit board carrying electronic parts, a case holding said circuit board, and a group of a plurality of bus bars fixed to said case by insert molding, wherein said bus bars each comprise a terminal portion having a distal end and a proximal end and including a portion of a constant width, and a base portion contiguous with said proximal end and having a width larger than said constant width, wherein said base portions of said respective bus bars are arranged parallel to each other in a width direction thereof, wherein each of said bus bars is bent at a bent portion of its base portion such that the distal end of its terminal portion is directed toward said circuit board, wherein said terminal portion of each of said bus bars extends through said circuit board and is soldered to and electrically connected to a terminal connecting portion of an electrical circuit on said circuit board at a soldered portion, and wherein said bent portions of alternate ones of said bus bars are offset from the bent portions of the other bus bars in a longitudinal direction of said bus bars, whereby said soldered portions of said respective terminal portions are arranged in a staggered manner.
