Abstract
An alternator rectifier assembly includes a rigid load bearing bushing intermediate a stator terminal board and a positive heat sink, wherein a minimum separation distance between the stator terminal board and the positive heat sink is defined by the bushing. The rectifier assembly further includes plurality of radiator connectors electrically connecting diode leads, wherein the radiator connectors are at least partially spaced from a top surface of the stator terminal board. The rectifier assembly further contemplates a stator terminal board frame, wherein terminals are located on the top surface of the stator terminal board, and the stator terminal board includes at least one cut out.
Claims28
An alternator rectifier assembly comprising:
- (a) a stator terminal board having a top surface and a bottom surface;
- (b) a plurality of a first and a second diode leads extending through the stator terminal board to terminate at a distance spaced from the top surface;
- and
- (c) a radiator connector electrically connecting at least two diode leads above the top surface of the stator terminal board.
An alternator rectifier assembly comprising:
- (a) a stator terminal board having a top surface, a bottom surface and a through aperture having a stop spaced from the bottom surface;
- (b) a positive heat sink spaced from the bottom surface of the stator terminal board;
- and
- (c) a bushing within the through aperture and contacting the stop, the bushing projecting from the stator terminal board a sufficient distance to preclude load bearing contact between the bottom surface of the stator terminal board and the positive heat sink.
An alternator rectifier assembly comprising:
- (a) a stator terminal board having a top surface, a bottom surface and an embedded conductor intermediate the top surface and the bottom surface, and a socket extending from the bottom surface to the embedded conductor;
- (b) a heat sink spaced from the bottom surface of the stator terminal board;
- and
- (c) a bushing within the socket and electrically connecting the embedded conductor to the heat sink, the bushing projecting from the socket a sufficient distance to preclude load bearing contact between the bottom surface of the stator terminal board and the heat sink.
