Abstract

A camera for mounting on a vehicle includes a front housing member that holds a lens member, an imaging element and a circuit board with a set of front electrical connectors thereon, and a rear housing member that holds a set of rear electrical connectors that are directly mounted to the front electrical connectors. The rear housing member is aligned to the front housing member with respect to a first axis. The front and rear electrical connectors are able to accommodate misalignment along two axes which are generally orthogonal to each other and to the first axis. The front and rear electrical connectors may be directly connected so that a jumper wire is not needed. Also, by aligning the front and rear housing members, the overall space occupied by the camera may be reduced.
