A wire conductor embedded in a circuit board for interconnecting rectifier diodes passes through a cut-out of the circuit board and is bent out of the cut-out beyond the surface of the circuit board so as to provide a U-shaped connection piece in which the end of a generator winding wire can be laid and clamped until it is soldered. The U-shaped connection piece can also be provided by a clip affixed to the embedded wire where it is accessible in a cut-out of the circuit board.

To provide an inexpensive assembly of a brush-holder and brush to engage the slip rings of an automotive-type alternator, particularly for low-cost, high-quantity mass production, a brush carrier arm, for example of leaf spring or circular spring material, is directly connected to hold a brush at one end thereof, for example by clamping the brush, securing it in a socket, or carrying an insulated brush-holder plate to which the brushes themselves are attached, the brush-holder arm being secured to a base which may be integral with, or form the cover of a housing for an electronic voltage regulator, so that the brush-holder itself will provide the spring engagement force for reliable electrical contact while permitting functioning also as an electrical connection and permitting inexpensive manufacture.
