Patent attributes
A sensing device for a vehicular sensing system includes a housing having a front housing portion and a metallic rear housing portion. A first printed circuit board and a second printed circuit board are disposed in the housing. The second printed circuit board is electrically connected to the first printed circuit board, which has an electrical connector for electrically connecting the sensing device to a vehicle wire harness. The second printed circuit board has circuitry thereat, with the circuitry generating heat when the sensing device is operating. The rear housing portion comprises a thermally conductive element that extends through an aperture of the first printed circuit board and is thermally coupled at the second printed circuit board. The thermally conductive element conducts heat generated by the circuitry of the second printed circuit board to the rear housing portion to dissipate the heat from the sensing device.
