Abstract:
1. An apparatus, comprising: a heat dissipating device defining a fastening site; a printed wiring board with electronic circuitry defining a bus with an interconnection pad and a board opening through at least a portion of the pad, the board opening being aligned with the fastening site; an electrical bus bar connected to the interconnection pad and defining a bus bar passageway that extends from a first side to a second side, the bus bar passageway is aligned with the board opening to define at least a portion of a passage to the fastening site and includes a bevel to provide a larger opening on the second side than the first side, the second side being closer to the interconnection pad than the first side; an electrically insulative grommet defining a first end portion opposite a second end portion, the second end portion being shaped with a flange, the first end portion being inserted into the passage with the flange abutting the bus bar about the bus bar passageway on the first side, the bevel and the grommet cooperating to define a clearance space therebetween; and a fastener extending through the grommet to provide a mechanical connection of the printed wiring board and the bus bar to the fastening site and maintain thermal contact between the printed wiring board and the heat dissipating device while electrically insulating the fastener from the bus bar with the grommet.
