CAMERA MODULE Russian patent published in 2013 - IPC G02B7/04 

FIELD: physics.

SUBSTANCE: camera module has a lens holder element for holding an optical system for capturing images, and a drive module for moving the lens holder element along the optical axis of the optical system for capturing images, wherein the lens holder element is a cast component which is cast using a mould and has a cast gate area remaining on its surface which corresponds to the cast gate of the mould, and the drive module has a coil placed on the exterior outline of the lens holder element, and a magnet facing the exterior outline of the coil. According to the invention, an area of the exterior outline of the lens holder element and an area of the inner outline of the coil bound a cut for filling with an adhesive, which is open in a direction parallel to the optical axis. The cut for filling with an adhesive has a bottom surface located on the lens holder element and facing a direction parallel to the optical axis. Said cast gate area is located on said bottom surface and the area of the exterior outline of the lens holder element and the area of the inner outline of the coil are joined by the adhesive which fills the cut for filling with adhesive, and the cast gate area is immersed in the adhesive.

EFFECT: efficient prevention of formation of dust from the cast gate area without need for a special treatment process.
