Document Type and Number:
WIPO Patent Application WO/2021/212419
Kind Code:
A1
Abstract:
Disclosed are a sealing ring (10), a lens, a camera module, an electronic device and a mold (20). The sealing ring comprises an annular ring (100), wherein the orthographic projection on a projection surface (200), of the annular ring is a first projection; the projection surface (200) is perpendicular to the axial direction of the annular ring (100); the first projection is annular and comprises a first outer ring line (210) located on the outer side; the first outer ring line (210) is formed by the projection of a second outer ring line (110) on an outer surface wall (140) of the annular ring (100); the outer surface wall (140) of the annular ring (100) comprises a burr zone; burrs are formed on the burr zone during injection molding of the sealing ring (10); and at least part of the second outer ring line (110) is located outside the burr zone. When the annular ring (100) is used for sealing, the second outer ring line (110) abuts against an external component, and when burrs or residual burrs on the second outer ring line (110) are reduced, the tightness of contact between the sealing ring (10) and the external component can be enhanced, thereby improving the sealing effect of the sealing ring (10).
