1. 1 A vehicular camera, the vehicular camera comprising:
a front housing portion comprising a lens;
a first circuit board having circuitry established thereat, wherein the first circuit board has a first side and a second side separated from the first side of the first circuit board by a thickness dimension of the first circuit board, and wherein the circuitry of the first circuit board comprises an imager at the first side of the first circuit board;
wherein the imager comprises a CMOS imaging array having at least one million photosensing elements arranged in rows and columns;
a second circuit board having circuitry established thereat, wherein the second circuit board has a first side and a second side separated from the first side of the second circuit board by a thickness dimension of the second circuit board;
wherein the second side of the first circuit board opposes the first side of the second circuit board;
wherein the circuitry of the second circuit board is in board-to-board electrical connection with the circuitry of the first circuit board;
wherein the circuitry of the second circuit board is electrically connected to an electrical connector at the second side of the second circuit board;
a rear housing portion having a connector for electrically connecting to an electrical connection end of a wire harness of a vehicle when the vehicular camera is disposed at the vehicle;
wherein the rear housing portion when joined with the front housing portion forms a camera housing with the first circuit board and the second circuit board disposed therein;
wherein the connector of the rear housing portion comprises a multi-pin connector having at least three pins that, with the rear housing portion joined with the front housing portion, insert into and electrically connect to respective receiving sockets of the electrical connector at the second side of the second circuit board;
wherein the pins of the multi-pin connector comprise a video signal pin and a ground-connect pin;
wherein the connector of the rear housing portion comprises an electrically conductive metallic clamping element that is in electrically conductive connection with the ground-connect pin of the multi-pin connector and electrically isolated from the video signal pin of the multi-pin connector;
wherein, when the pins of the multi-pin connector insert into and electrically connect to respective receiving sockets of the electrical connector at the second side of the second circuit board, the electrically conductive metallic clamping element engages a metallic shield element at the electrical connector to establish a ground path from the connector of the rear housing portion to the second circuit board; and
wherein, with the vehicular camera disposed at the vehicle and with the connector electrically connected to the electrical connection end of the wire harness of the vehicle, image data captured by the camera is provided to an electronic control unit (ECU) of the vehicle via signal communication from the vehicular camera to the ECU.
