Rectifier arrangement
First Claim
1. Rectifier supporting device for attachment to a circular end shield of a housing of a generator designed for use in motor vehicles, comprising two facing carrier plates of a heat conducting material for supporting rectifying diodes having head wires;
- a circuit board of electrically insulating material in which conductors for circuit connections of the diodes and of stator wires of the generator are embedded;
the circuit board being arranged between the carrier plates;
each of the carrier plates and the circuit board having a shape of a circle segment approximating more than a half of the circular shape of the end shield to define a segment-like cutout for accommodating a brush holder of the generator;
one of the carrier plates being constructed as a positive heat sink and the other carrier plate as a negative heat sink; and
the two heat sinks and the circuit board being arranged coaxially in separate planes at an axial distance one from each other.

Abstract
In a rectifier supporting device for (three-phase) generators which is intended particularly for motor vehicles, buses and the like, cooling plates carrying the rectifier diodes are constructed as heat sinks following the circular shape of an end shield of the generator and segment-like cut out portion for a brush holder of the generator. Each of the heat sinks is supported at an axial distance from, but coaxial with, a circuit board arranged between the two heat sinks. The circuit board has a shape corresponding to that of the heat sinks and provides electric connections to the diode head wires and stator wires.
In an advantageous construction of the circuit board, sheathe-like guides extend downward until adjacent to the stator phase windings and receive the stator wires guided up toward the circuit board in an insulated passage through the facing three-phase generator housing parts and heat sink areas.
