Camera module and its bracket

Abstract

A bracket for a camera module, having a first surface and a second surface arranged in parallel and an outer wall connected to the first surface and the second surface, the bracket is provided with a light-transmitting hole penetrating the first surface and the second surface, The first surface is used to connect with the focus drive mechanism of the camera module, the second surface is used to connect with the circuit board of the camera module, and the outer wall is provided with a bearing surface, which is used to bear against the welding of the focus drive mechanism For the pin, the abutting surface intersects the first surface and the second surface, and the abutting surface forms a first obtuse angle with the first surface. The bracket can effectively reduce the thrust exerted by its bearing against the welding pins, thereby effectively avoiding the tendency of the welding pins to move outward, thereby making the welding pins and pads firmly connected, so that the camera using the above-mentioned bracket The module has good electrical performance. The invention also provides a camera module.

Description

technical field [0001] The invention relates to the technical field of electronic equipment, in particular to a camera module and its bracket. Background technique [0002] In order to improve image quality, electronic products such as mobile phones and tablets are usually equipped with camera modules with focusing functions. A camera module with a focus function generally includes a lens, a focus drive mechanism, a bracket, an image sensor, and a circuit board. The focus drive mechanism is provided with soldering pins for electrical connection with the circuit board. Among them, the focus driving mechanism usually adopts a voice coil motor (voice coil motor, VCM). The voice coil motor includes an assembly cylinder that is threadedly connected with the lens and can move back and forth in the axial direction. The two ends of the assembly cylinder are clamped on two metal shrapnels. And a conductive coil is wound outside the assembling cylinder. The two ends of the conductiv...

Problems solved by technology

However, since the bearing surface of the existing bracket is a vertical plane, that is, it is perpendicular to the upper and lower surfaces of the bracket (the upper and lower surfaces of the bracket are parallel), so that the right angle formed between the bearing surface and the upper surface abuts against the welding pin, and A thrust will be applied to the soldering pins, causing the soldering pins to move outwards. In this way, the soldering pins and pads will not be welded firmly, which will affect the electrical performance of the camera module with focusing function
