Problems solved by technology

[0003] However, the materials of the lens holder and the lens barrel of the existing lens module are mostly plastics such as PC/ABS (polypropylene/acrylonitrile-butadiene-styrene) engineering plastics, polytetrafluoroethylene, etc., which usually do not have good Anti-electromagnetic wave interference ability, image sensor components are susceptible to external electromagnetic wave interference and generate noise, the electromagnetic wave interference can be passed a

Embodiment Construction

[0009] The lens module 10 provided by the embodiment of the present invention will be further described below with reference to the accompanying drawings.

[0010] see figure 1 and figure 2 , the lens module 10 provided by the embodiment includes a lens barrel 110 , a filter 120 , a spacer ring 130 , a lens group 140 and a lens holder 150 .

[0011] The lens barrel 110 is a hollow cylinder for accommodating the filter 120 , the spacer ring 130 and the lens group 140 . The lens barrel 110 includes a first end portion 111 and an opposite second end portion 112 . The first end portion 111 is provided with a light entrance hole 113 through which light can enter the lens module 10 and pass through the filter 120 and the lens module 140 sequentially. The outer wall of the lens barrel 110 can be provided with threads for matching with the threads of the lens holder 150 so that the lens barrel 110 can be fixed on the lens holder 150 . Of course, the lens barrel 110 can also be fi...

Abstract

The invention provides a lens module, comprising a lens seat and a drawtube which is fixed with the lens seat; the external surface of the lens seat is sleeved by an electromagnetic shielding housing; the shape of the electromagnetic shielding sleeve is matched with the external surface of the lens seat; and the material of the electromagnetic shielding sleeve is metal. The lens module is provided with the electromagnetic shielding sleeve on the external surface of the lens seat; the electromagnetic shielding sleeve is made of metal material and has good electromagnetic wave interference resistance capability, can effectively shield the environmental electromagnetic wave, and greatly reduces the interference of the electromagnetic wave on the image sensing element matched with the lens module, thus improving the imaging quality.

Description

technical field [0001] The invention relates to a lens module, in particular to a lens module with good anti-electromagnetic wave interference capability. Background technique [0002] The camera function has become one of the indispensable main functions of various portable electronic products such as mobile phones and personal digital assistants (PDAs). A camera module usually includes at least one lens module, and an image sensor element disposed opposite to the lens module. The lens module usually includes a lens mount, a lens barrel disposed on the lens mount, and optical components such as a lens group, a spacer ring, and an optical filter sequentially fixed in the lens barrel along the optical axis direction. The image sensor element is usually packaged in the lens holder, or directly packaged at the bottom of the lens barrel, and is used for imaging in cooperation with the lens module. [0003] However, the materials of the lens holder and the lens barrel of the ex...
