OPTICAL LENS MODULE AND ASSEMBLY METHOD FOR SAME
Document Type and Number:
WIPO Patent Application WO/2012/008284
Kind Code:
A1
Abstract:
Disclosed are an optical lens module and an assembly method for same, whereby rattling between a holder and a lens barrel can be suppressed and the generation of abrasion powder caused by abrasion between the lens barrel and the holder when attaching the lens barrel can be reduced. When attaching the lens barrel (12) to the holder (20), hook pieces (14) formed on the lens barrel (12) are bent inwards and held in this state while the lens barrel (12) is inserted into the inner circumferential surface of the holder (20), and then the hook pieces (14) are elastically returned. The screw sections (15) of the elastically returned hook pieces (14) are elastically pushed into the screw section (21) formed in the inner circumferential surface of the holder (20), and the lens barrel (12) is inserted inside the holder (20).
