Abstract
In an alternating current generator for vehicles, an output terminal of a rectifier circuit is tightly fixed to a positive-polarity side heat radiation fin by tightening a nut. A resin bushing is fitted around the nut to insulate electrically the output terminal. The bushing has a flange on its outer peripheral surface. A rear cover made of resin is attached to cover the flange, so that the rear cover restrains the bushing from moving along and turning around the output terminal.
Claims11
An alternator for vehicles comprising:
- a frame supporting a rotary shaft therein;
- a rectifier circuit, provided outside said frame, having an output terminal from which a generated electric output power is produced;
- a protective member surrounding said output terminal for electrical insulation;
- and
- a rear cover, provided separately from said frame, to cover said rectifier circuit,
- wherein said rear cover is attached to a rear side of said frame to cover at least a part of said output terminal and fix said protective member between said frame and said rear cover.

An alternator for vehicles comprising:
- a frame supporting a rotary shaft therein;
- a rectifier circuit, provided outside said frame, having an output terminal from which a generated electric output power is produced;
- and
- a protective member surrounding said output terminal for electrical insulation, said protective member has an engagement part, having a surface inclined at an angle other than 90.degree. relative to a longitudinal axis of said output terminal and located on an outer periphery thereof, that engages said engagement part with an edge part of a rear cover to fix said protective member in direct contact with said frame, wherein said rear cover is provided separately from said frame to cover said rectifier circuit, said surface of said engagement part is positioned to face said rear cover,
- wherein said rear cover is attached to a rear side of said frame to cover at least a part of said output terminal and fix said protective member between said frame and said rear cover.

- and
- a rear cover, provided separately from said frame, to cover said rectifier circuit, wherein said rear cover is attached to a rear side of said frame to cover at least a part of said output terminal and fix said protective member between said frame and said rear cover;
- an output lead electrically connected to said output terminal;
- a first nut fitted around said output terminal between said output terminal and said protective member, said first nut having an axial length longer than that of said protective member;
- and
- a second nut fitted around said output terminal to press said output lead to said first nut while maintaining non-contact between said output lead and said protective member.
