Flexible lead for a pressfit diode bridge
View Patent ↗An improvement to a bridge rectifier assembly of the type used to convert alternating current produced by an motor vehicle alternator into direct current. The bridge rectifier assembly of this type comprises a heat sink, a plurality of pressfit diodes installed in the heat sink, and a plurality of terminals electrically connected to the motor vehicle alternator. The first end of a flexible conductor is mechanically and electrically connected to a conductive connector. The second end of the flexible conductor is mechanically and electrically connected to a lead of one of the plurality of pressfit diodes. The conductive connector is electrically connected to one of the plurality of terminals to complete an electrical connection between the one of the plurality of pressfit diodes and the one of the plurality of terminals.
1. A rectifier assembly comprising:
a heat sink;
a diode installed in said heat sink, said diode having at least one lead; and
an insulator installed adjacent to said diode, said insulator comprising a plurality of wings arranged over said diode in a manner that enhances electrical insulation between said at least one lead and said heat sink.
2. The rectifier assembly of claim 1 , wherein said heat sink, said diode, and said insulator form a cavity, the rectifier assembly further comprising:
a non-conductive polymer material injected in said cavity.
3. In a bridge rectifier assembly of the type used to convert alternating current produced by a motor vehicle alternator into direct current, the bridge rectifier assembly comprising a heat sink, a plurality of pressfit diodes installed in the heat sink, and a plurality of terminals electrically connected to the motor vehicle alternator, an improvement comprising:
a flexible conductor having a first end and a second end, said first end of said flexible conductor being mechanically and electrically connected to a conductive connector, said second end being mechanically and electrically connected to a lead of one of said plurality of pressfit diodes, said conductive connector being electrically connected to one of said plurality of terminals to complete an electrical connection between said one of said plurality of pressfit diodes and said one of said plurality of terminals; and
an insulator installed adjacent to at least one of said plurality of pressfit diodes, said insulator comprising a plurality of wings arranged over said at least one of said plurality of pressfit diodes in a manner that enhances electrical insulation between said at least one of said plurality of pressfit diodes and said heat sink.
