车用交流发电机
Abstract:
本发明获得一种车用交流发电机，能抑制整流元件的可靠性和发电机的冷却性的降低，并且能缩小整流装置的轴向尺寸。在上述整流装置(30、30A、30B、30C)中，将第一整流元件连接部(42)以间隙配合的状态配设在形成于第二整流元件保持部(36)的第二贯通孔(46)内，且将第二整流元件连接部(41)以间隙配合的状态配设在形成于第一整流元件保持部(32)的第一贯通孔(45)内，从而使电路板(40、40A、40B)配设在第一整流元件保持部(32)与第二整流元件保持部(36)之间，多个第一整流元件(28)的第一引线电极(28b)分别沿轴向延伸，并与第一整流元件连接部(42)分别连接，多个第二整流元件(29)的第二引线电极(29b)分别沿轴向延伸，并与第二整流元件连接部(41)分别连接。
Abstract(English):

The present invention provides an automotive alternator that can reduce axial dimensions of a rectifying apparatus while suppressing reductions in reliability of rectifying elements and cooling of the alternator. In this rectifying apparatus, a circuit board is disposed between a first rectifying element holding portion and a second rectifying element holding portion such that first rectifying element connecting portions are disposed in a loosely fitted state inside a second penetrating aperture that is formed on the second rectifying element holding portion, and second rectifying element connecting portions are disposed in a loosely fitted state inside a first penetrating aperture that is formed on the first rectifying element holding portion; first leading electrodes of a plurality of first rectifying elements respectively extend axially and are connected to each of the first rectifying element connecting portions; and second leading electrodes of a plurality of second rectifying elements respectively extend axially and are connected to each of the second rectifying element connecting portions.
