Abstract

The invention provides a camera module group, comprising a substrate, an image sensing wafer with a sensing area, a drawtube and a lens mount. The drawtube is sleeved at one end of the lens mount. The substrate is adhesively connected with the end face of the lens mount which is away from the drawtube. The surface of the substrate is provided with a first groove; and a second groove is arranged at the groove bottom of the first groove. At least an electronic element is housed on the second groove; and the groove bottom of the first groove is provided with at least a zero potential contact. A cover plate covering the second groove is arranged at the groove bottom of the first groove. The cover plate is electrically connected with the zero potential contact; and the image sensing wafer is adhesively connected on the cover plate and at the surface away from the second groove. The image sensing wafer is electrically connected with the substrate. A light penetration element, the image sensing wafer, the cover plate and the electronic element are housed in the space structured by the lens mount and the substrate. The camera module group achieves electromagnetic shielding, so that the image sensing wafer is free of electromagnetic interference.

Description

technical field

[0001] The invention relates to a camera module, in particular to a camera module that can effectively prevent electromagnetic interference. Background technique

[0002] see figure 1 , is a sectional view of a camera module 1 provided in the prior art, which includes a lens barrel 2 , a lens holder 3 and an image sensing chip 4 . The surface of the lens barrel 2 is provided with external threads. The mirror base 3 has a through chamber, and an internal thread is provided at one end of the inner wall of the mirror base 3 chamber. The external thread of the lens barrel 2 is engaged with the internal thread of the lens base 3 , so that the lens barrel 2 is sleeved on one end of the lens base 3 . A glass sheet 6 is bonded to the surface of the image sensing chip 4 for protecting the sensing area of ​​the image sensing chip 4 . The image sensing chip 4 is bonded on the surface of a substrate 5 , and its sensing area faces away from the substrate 5 . A passiv...
