Abstract:
1. A dynamoelectric machine comprising: a rectifier apparatus having positive-side and negative-side heat sinks each mounted with a plurality of diode elements; and a circuit board made of a resin in which insert conductors for connecting said diode elements are insert molded, said rectifier apparatus being mounted to a housing by electrically-connecting said negative-side heat sink to said housing and fastening said positive-side and negative-side heat sinks and said circuit board to a mounting surface of said housing; an output terminal for externally extracting output from said rectifier apparatus; and a wiring harness terminal mounted to said output terminal, wherein: an output terminal mount portion is formed so as to project in an axial direction of said dynamoelectric machine from a first end of said positive-side heat sink; said output terminal has an external screw thread portion disposed on an output extraction end thereof, said output terminal being disposed by mounting an opposite end from said extraction end to said output terminal mount portion such that said external screw thread portion projects outward in said axial direction through an extraction aperture formed in said housing; a tubular relay member is mounted to said output terminal so as to be fitted over said output extraction end of said output terminal and is fastened between said output terminal mount portion and a relay member mounting nut screwed onto said external thread portion of said output terminal such that said relay member is in a state of surface contact with said output terminal mount portion and said relay member mounting nut; said wiring harness terminal is fastened between said relay member mounting nut and a wiring harness terminal mounting nut screwed onto said external thread portion of said output terminal such that said wiring harness terminal is in a state of surface contact with said relay member mounting nut and said wiring harness terminal mounting nut; and a tubular electrically-insulating member is disposed so as to cover an output extraction end of said output terminal mount portion and said relay member, wherein said electrically-insulating member is molded integrally with said relay member, and knurling is applied to an outer peripheral surface of said relay member.
