Vehicle AC generator

摘要

Provided is a vehicle AC generator that further enhances safety at the time of a vehicle collision, without resorting to changes in material or changes in overall thickness. A vehicle AC generator 50 has: a rotor 5 provided on a shaft 4; a stator 10 disposed so as to oppose the rotor; a rectifier 12 rectifying current generated in the stator; a regulator 13 adjusting voltage generated in the stator; and a resin cover 14 covering the rectifier. A partitioning section 15 is integrally formed on the inner side of the resin cover. The partitioning section extends in the peripheral direction and rises in the axial direction of the shaft.

1. A vehicle AC generator, comprising:
a rotor provided on a shaft; a stator disposed so as to oppose the rotor; a rectifier rectifying current generated in the stator; a regulator adjusting voltage generated in the stator; and a resin cover covering the rectifier, wherein a partitioning section is integrally formed on the inner side of the resin cover; wherein the partitioning section extends in a peripheral direction and rises in an axial direction of the shaft, wherein the rectifier has a plurality of first diodes, respective heat generation sections of which are electrically connected to respective cathodes, and a plurality of second diodes, respective heat generation sections of which are electrically connected to respective anodes; and wherein the partitioning section extends so as to separate a first heat sink to which the cathodes of the plurality of first diodes are electrically connected, from a second heat sink to which the anodes of the plurality of second diodes are electrically connected.
