  • Bridge rectifier with insulating support having expandable legs
    Patent number: 5866963
    Abstract: A bridge rectifier for an alternator comprises a first heat sink for being secured to a frame of an alternator; a second heat sink disposed on top of the first heat sink; an electrical insulator disposed between the first and second heat sinks; a first group of diodes operably secured to the first heat sink; a second group of diodes operably secured to the second heat sink; an insulating support operably secured to the second heat sink, the support including a plurality of legs adapted to be received in respective holes in the second heat sink; a plurality of screws adapted to be received axially by respective legs, the screws being adapted to expand the legs radially, thereby to lock the legs in respective holes; and a plurality of electrical connectors each being operably connected to a respective pair of diodes, each pair comprising a diode from the first group and a diode from the second group, each of the plurality of electrical connectors for being operably connected to the alternator, each of the plura

  • Heat sink assembly
    Patent number: 4701828
    Abstract: A heat sink mounting assembly for heat producing devices has a mounting plate with a plurality of positioning areas in which the heat producing devices are fixedly mounted by cooling fins punched out from the mounting plate and which leave convection openings through which cooling air circulates, the cooling fins and convection openings being proportioned to provide maximum cooling effect.
