  • Publication number: 20230071152
    Abstract: A camera assembly comprises a lens assembly supported on a support structure, wherein the lens assembly includes an autofocus actuator arrangement and the camera assembly includes an optical image stabilization assembly arranged to move the lens assembly in a plane perpendicular to the optical axis. A flexible printed circuit tape connected between the support structure and the lens assembly and providing an electrical connection to the auto-focus actuator arrangement is bent around a corner, thereby allowing the flexible printed circuit tape to accommodate the motion of the lens assembly perpendicular to the optical axis. A crimp plate connected to the lens assembly which crimps shape memory alloy wires has features extending out of the plane of the crimp plate for reducing flexibility. At least part of the optical image stabilization assembly overlaps the lens assembly in the direction along the optical axis, thereby reducing the height of the camera assembly.

  • Publication number: 20170219842
    Abstract: A camera assembly comprises a lens assembly (20) supported on a support structure (4), wherein the lens assembly includes an autofocus actuator arrangement (24) and the camera assembly includes an optical image stabilization assembly (40) arranged to move the lens assembly in a plane perpendicular to the optical axis. A flexible printed circuit tape (103) connected between the support structure (4) and the lens assembly (20) and providing an electrical connection to the auto-focus actuator arrangement (24) is bent around a corner, thereby allowing the flexible printed circuit tape (103) to accommodate the motion of the lens assembly perpendicular to the optical axis. A crimp plate (62) connected to the lens assembly which crimps shape memory alloy wires (80) has features (63) extending out of the plane of the crimp plate for reducing flexibility.
