摘要： There is provided a plastic lens, a lens module and a lens injection mold. The plastic lens includes an effective aperture portion being an optical surface of the lens and a rib portion being a circumferential portion of the lens. The effective aperture portion and the rib portion are shaped in concentric circles having the same central axis. The rib portion includes three or more concave portions in an outer circumferential portion thereof, the concave portions being positioned to be symmetrical with respect to the central axis. The plastic lens is designed to be symmetrical with respect to a concentric axis so that it may avoid asymmetric contraction inside a barrel. Also, since the concave portions, when assembled in the barrel, do not contact an inner circumferential surface of the barrel, press-fitting force in the assembly thereof is reduced so that deformation caused by excessive press-fitting force applied thereto may be avoided.
摘要翻译：提供塑料透镜，透镜模块和透镜注射模具。塑料透镜包括作为透镜的光学表面的有效开口部分和作为透镜的圆周部分的肋部分。有效开口部分和肋部分成形为具有相同中心轴的同心圆。肋部在其外周部分包括三个或更多个凹部，凹部相对于中心轴线对称。塑料透镜被设计成相对于同心轴对称，使得其可以避免桶内的不对称收缩。此外，由于凹部在组装在筒体中时不与筒体的内周面接触，因此其组装中的压配合力降低，从而可以避免施加于其上的过大的压配力引起的变形。
