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 includes a voice coil motor 10, a lens 20, a base bracket 30, an image sensor 40 and a circuit board 50.

[0020] The voice coil motor 10 is generally a rectangular parallelepiped, and includes a conductive housing 11, a first surface 12 and a second surface 13 opposite to the first surface 12.

[0021] The conductive housing 11 includes a first side surface 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 alloys, conductive plastics, surface conductive materials, and conductive glass.

[0022] A first receiving groove 14 for receiving the lens 20 is opened in the middle part of the first surface 12. The first receiving groove 14 penetrates through the first surface 12 an...

Abstract

A camera module includes a voice coil motor, a lens, a base bracket supporting the voice coil motor and the lens, an image sensor and a circuit board accommodated in the base bracket. The voice coil motor includes a first receiving slot and a pin, the pin is electrically connected with the circuit board, and the lens is accommodated in the first receiving slot. The image sensor is attached to the circuit board and is opposite to the lens. The base support is located between the voice coil motor and the circuit board. An electroplating circuit layer is formed around the base support. The electroplating circuit layer is connected to the voice coil motor and the circuit board The solder phase is electrically connected. The camera module provided by the present invention has a simple process, can eliminate external electromagnetic interference to the camera module, and can prevent the electromagnetic of the voice coil motor from affecting the work of its external electronic components, and can reduce costs and improve yield.

Description

Technical field [0001] The invention designs the field of camera modules, and in particular relates to a camera module capable of preventing external electromagnetic interference. Background technique [0002] The camera module is a micro-optoelectronic product, and the normal operation of the camera module will be affected by the appearance of noise signals due to external electromagnetic interference (EMI). Therefore, an anti-EMI design is required. [0003] The existing anti-EMI design uses an external grounded metal shell as a shield to electromagnetic interference. The metal shell is mainly manufactured by extrusion molding, but the cost of mold opening for extrusion molding is too high, and the metal shell is light and thin, and easy to deform, resulting in low yield. Summary of the invention [0004] Therefore, the present invention provides a camera module capable of reducing cost. [0005] A camera module including [0006] A voice coil motor, the voice coil motor includes a...
