Camera for vehicle vision system
First Claim
1. A camera module for a vision system for a vehicle, wherein said camera module is configured to be disposed at a vehicle so as to have a field of view exterior of the vehicle, said camera module comprising:
- a metal housing including a side wall of a cavity that houses a printed circuit board having an imager disposed thereat, said side wall having a rear end circumscribing an opening at a rear portion of said metal housing;
a lens holder comprising a lens assembly, wherein said lens holder is attached at a front portion of said metal housing so that said lens assembly is optically aligned with said imager;
a metal rear cover attached at said rear end of said side wall at said rear portion of said metal housing so as to be disposed at said opening at said rear portion of said metal housing;
a connecting element disposed at said metal rear cover and extending forward from said metal rear cover into said cavity towards said printed circuit board, said connecting element electrically connecting to circuitry at said printed circuit board when said metal rear cover is attached at said rear end at said rear portion of said metal housing; and
a connector portion disposed at said metal rear cover, wherein an outer portion of said connecting element extends rearward from said metal rear cover and is disposed in said connector portion so as to be electrically connectable to electrically conductive elements of a vehicle connector when said camera module is disposed at the vehicle and the vehicle connector is connected to said connector portion.

Abstract
A camera module for a vision system for a vehicle includes a housing, a lens holder and a rear cover. The housing houses a printed circuit board having an imager disposed thereat. The lens holder is attached at a front portion of the housing so that a lens assembly is optically aligned with the imager. The rear cover attaches at an opening at a rear portion of the housing and includes a connecting element for electrically connecting to circuitry at the printed circuit board when the rear cover is attached at the opening at the rear portion of the housing. An outer portion of the connecting element is disposed in a connector portion of the rear cover so as to be electrically connectable to electrically conductive elements of a vehicle connector when the camera module is disposed at the vehicle and the vehicle connector is connected to the connector portion.
