Abstract
Abstract A multiphase, full-wave rectifier assembly for an alternator has first and second mutually parallel plates carrying first and second sets of diodes. Connectors electrically connect terminals of respective diodes of the first and second sets with each other and with terminals of respective field diodes heads of a multiphase stator of the alternator are connected respectively with the connectors. Each field diode is held in a respective recess defined between first and second plates of a common electrical connector for the field diodes. Each recess is defined by a U-shaped portion in the first plate of the common electrical connector and a part of the second plate of the common electrical connector, said part closing the U-shaped portion. Deformable tags on the ends of the U-shaped portions pass through corresponding slots in the second plate of the common electrical connector and are deformed so as to hold said plates together.
