Abstract
An alternator is provided with a rectifier including a positive-side and a negative-side heatsink that cool rectifier elements corresponding to each heatsink and a circuit board that holds the positive-side and the negative-side heatsink, wherein one of either the positive-side and the negative-side heatsink or the circuit board is provided with engaging holes, and the other with engaging protrusions that are engaged with the holes.
Claims18
An alternator, comprising:
- a rectifier including a positive-side heatsink and negative-side heatsink for cooling rectifier elements corresponding to each heatsink, and
- a circuit board, having a front side and an opposing rear side, for holding the positive-side heatsink and the negative-side heatsink;
- wherein one or more engaging holes are centrally aligned along an axis, the axis being along a longitudinal length of the one or more engaging holes, and provided on at least one of (a) the positive-side heatsink and the negative-side heatsink and (b) opposite sides of the circuit board, and
- wherein one or more corresponding engaging protrusions that are engaged with each engaging hole, are provided, such that an engaging protrusion is provided on at least one of (c) opposite sides of the circuit board aligned along axis and (d) the positive-side heatsink and the negative-side heatsink aligned along the axis, respectively, and
- wherein antivibration protrusions, each for abutting a surface of the positive-side heatsink and that of the negative-side heatsink, are formed at predetermined locations on an insulation resin portion constituting the circuit board.
