Embodiment Construction

[0018] The structure of a camera module provided by the present invention will be further described below with reference to the drawings and embodiments.

[0019] see Figure 1 to Figure 2 , a camera module 100 comprising a voice coil motor 10, a lens 20, a base bracket 30, a conductive tape 40, a filter 50, an image sensor 60, a circuit board 70 and a protective cover 80 .

[0020] The voice coil motor 10 is generally in the shape of a cuboid, and includes a conductive shell 11 , a first surface 12 and a second surface 13 opposite to the first surface.

[0021] The conductive shell 11 includes a first side 111 perpendicular to the first surface 12 and the second surface 13 . The conductive shell 11 can be made of magnetic shielding materials such as nickel-iron alloy, conductive plastic, surface conductive material, and conductive glass.

[0022] A middle portion of the first surface 12 defines a first receiving groove 14 for receiving the lens 20 . The first receiving gr...

Abstract

A camera module includes a voice coil motor, a lens module, a substrate, an imagine sensor, a circuit board and a conductive adhesive tape. The voice coil motor includes a conductive housing defining a first hole. The lens module is received in the first hole. The substrate supports the voice coil motor and defines a second hole. The circuit board includes a grounding area. The image sensor is supported by the circuit board, and is received in the second hole, and aligned with the lens module. The conductive adhesive tape covers the substrate and electrically connects the conductive housing to the grounding area.

Description

technical field [0001] The invention relates to the field of designing camera modules, in particular to a camera module capable of preventing external electromagnetic interference. Background technique [0002] The camera module is a micro-optical product. Due to external electromagnetic interference (EMI), there will be mixed signals, which will affect the normal operation. Therefore, an anti-EMI design is required. [0003] Existing anti-EMI designs utilize grounded metal enclosures as shields to prevent electromagnetic interference. Metal casings are mainly manufactured by extrusion, but the cost of mold opening is too high. In addition, the metal shell is light and thin, easily deformed, and difficult to operate, resulting in a low yield rate. Contents of the invention [0004] Therefore, the present invention provides a camera module capable of reducing costs. [0005] A camera module comprising [0006] A voice coil motor, the voice coil motor includes a conducti...
