Lens device and method of assembly of lens device

摘要

A lens device for mounting a flexible printed circuit board in a lens barrel and method of assembling the flexible printed circuit board in the lens barrel of the lens device is disclosed. The lens device includes a through-channel on a portion of the lens barrel. The through-channel includes first and second tiers formed by a first partition and a second partition that is perpendicular to the first partition which divides the second tier into separate through-channels. The flexible printed circuit board is assembled in the lens device by inserting the flexible printed circuit board into the first tier from one end of said through-channel, folding the flexible printed circuit board at the other end of the through-channel into a folded part, and inserting the folded part of the flexible printed circuit board into one of the separate through-channels of the second tier from the other end of the through-channel.
