Automotive alternator rectifying apparatus

摘要

An automotive alternator rectifying apparatus includes a circuit board that connects a positive-side rectifying element mounted to the positive-side heatsink and a negative-side rectifying element mounted to the negative-side heatsink to configure a bridge circuit. The circuit board includes a tubular lead guiding portion that includes a lead insertion aperture; and a terminal that is disposed so as to extend outward in an aperture direction of the lead insertion aperture from an exit edge portion of the lead insertion aperture, and to which is connected a lead that is subject to connection that is inserted through an entrance of the lead insertion aperture and that extends outward from an exit, and the lead insertion aperture is formed such that cross-sectional area thereof becomes gradually smaller from the entrance toward the exit.

主权项

1. An automotive alternator rectifying apparatus that rectifies an alternating-current electromotive force that is generated in an automotive alternator stator into direct current, said rectifying apparatus comprising:
a positive-side heatsink to which a positive-side rectifying element is mounted; a negative-side heatsink that is disposed so as to be separated from said positive-side heatsink, and to which a negative-side rectifying element is mounted; 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 positive-side rectifying element and said negative-side rectifying element to configure a bridge circuit, wherein: said circuit board comprises: a tubular lead guiding portion that comprises a lead insertion aperture; and a terminal that is disposed so as to extend outward in an aperture direction of said lead insertion aperture from an exit edge portion of said lead insertion aperture, and to which is connected a lead that is subject to connection that is inserted through an entrance of said lead insertion aperture and that extends outward from an exit; and said lead insertion aperture is formed such that cross-sectional area thereof becomes gradually smaller from said entrance toward said exit except in a region in a portion near said entrance of said lead insertion aperture.
