Rectifier arrangement of vehicle AC generator

An AC generator for a vehicle including a multi-phase stator windings, a rectifier unit and a rectifier cover, wherein

• said rectifier unit comprises a terminal member having a plurality of connecting portions and a plurality of partition members disposed radially inner side of said connecting portions, and
• said rectifier cover has a plurality of drain holes at portions corresponding to said partition members.

An AC generator for a vehicle including a rotor, a stator having a three-phase stator winding with three output leads, a three-phase full-wave rectifier unit, an insulation cover, and a frame for rotatably supporting said rotor, said rectifier unit comprising:

• a cooling fin structure having at least three positive diodes and three negative diodes fixed thereto;
• and
• a terminal member having a wiring member connecting said positive and negative diodes to form said three-phase full-wave rectifier unit and at least three first partition members, said wiring member having first connecting portions connected to said positive and negative diodes and second connecting portions connected to said three output leads, each of said first partition members extending toward said insulation cover between one of said first connecting portions and said cooling fin structure.
