Abstract

A camera for a vision system of a vehicle includes a front housing portion having a lens, a circuit board having circuitry established thereat, and a plastic rear housing portion having a connector for electrically connecting to a connector end of a wire harness of the vehicle when the camera is disposed at the vehicle. The front housing portion is mated with the rear housing portion with the circuit board disposed therein. The rear housing portion includes internal wall structure establishing internal surfaces of the rear housing portion. The connector of the rear housing portion includes a multi-pin connector having terminals for electrically connecting to circuitry at the circuit board. An electrically conductive metallic shield element is formed to be disposed within the rear housing portion and to correspond with the internal surfaces of the rear housing portion.
