Abstract

The invention relates to the technical field of optical lenses, in particular to a lens, a camera module, electronic equipment and a mold. The lens comprises a lens barrel, a lens group, a compression ring and an optical filter, wherein the lens barrel is provided with a light through hole, and the lens barrel is provided with a first end face close to the object side and a second end face close to the image side in the axial direction of the light through hole; the lens group is accommodated in the light through hole; the pressing ring is fixedly arranged in the light through hole and abuts against the side, close to the second end face, of the lens set, and the inner wall of the pressing ring is sunken towards the outer wall of the pressing ring to form a first annular groove; and the peripheral edge of the optical filter is embedded in the first annular groove. According to the lens, the matching requirements among the pressing ring, the optical filter and the lens barrel are low, the processing difficulty of the lens is reduced, and the lens assembly yield is improved.

Description

technical field [0001] The invention relates to the technical field of optical lenses, in particular to a lens, a camera module, electronic equipment and a mould. Background technique [0002] With the development of technology, lenses have been widely used in various electronic devices, such as mobile devices and monitoring devices. However, there are still some deficiencies in the current structure of the lens, such as assembly tolerances between the pressure ring, optical filter and lens barrel in the lens, which seriously affect the assembly accuracy of the pressure ring, optical filter and lens barrel, and increase the cost of the lens. processing difficulty. Contents of the invention [0003] The application discloses a lens. In the lens, the requirements for cooperation among the pressure ring, the optical filter and the lens barrel are low, the processing difficulty of the lens is reduced, and the yield rate of the lens assembly is improved. [0004] In the first...
