Patent ID: 8692427

Claim:
An automotive alternator rectifying apparatus that rectifies alternating current by an alternating-current electromotive force that is generated in an automotive alternator stator into direct current, said rectifying apparatus comprising: a positive-side heatsink, and a plurality of positive-side rectifying elements mounted to said positive-side heatsink; a negative-side heatsink that is disposed so as to be separated from said positive-side heatsink, and a plurality of negative-side rectifying elements mounted to said negative-side heatsink; and a circuit board that is disposed so as to be stacked with said positive-side heatsink and said negative-side heatsink, and that connects said plurality of positive-side rectifying elements and said plurality of negative-side rectifying elements to configure a bridge circuit, wherein: said circuit board comprises: an electrically insulating first resin-molded body; an electrically insulating second resin-molded body that is stacked together with said first resin-molded body and integrated with said first resin-molded body; and a plurality of terminals each comprising: a positive electrode terminal portion, and a lead of at least one of said plurality of positive-side rectifying elements to be connected to said positive electrode terminal portion; a negative electrode terminal portion, and a lead of at least one of said plurality of negative-side rectifying elements to be connected to said negative electrode terminal portion; and a trunk portion that links said positive electrode terminal portion and said negative electrode terminal portion; and said plurality of terminals are each held between said first resin-molded body and said second resin-molded body so as to be separated from each other such that said trunk portion is disposed between mating surfaces of said first resin-molded body and said second resin-molded body, said positive electrode terminal portion is inserted through said second resin-molded body, and said negative electrode terminal portion is inserted through either said first resin-molded body or said second resin-molded body.
