ABSTRACT:
A vehicle alternator is disclosed having a stator, a rotor, a frame surrounding the stator and the rotor, a bowl-shaped end cover mounted on the frame and defining an electric component-part compartment, a brush unit held in sliding contact with slip rings of a rotary shaft, and a rectifier unit. The rectifier unit includes a terminal block embedded with A.C. conductive segments for multi-phase windings of a stator coil. The end cover includes a base wall portion and protective partitioned compartments axially protruding from a base wall portion of the end cover toward the frame at circumferentially spaced positions for the multi-phase windings, respectively, for surrounding at least one circumference of a connecting portion between an exposed end portion of each A.C. conductive segment and a diode lead and a connecting portion between the exposed end portion of each A.C. conductive segment and a stator lead.
