A camera module includes a printed circuit board (PCB), an image sensor fixed to the PCB, a lens holder fixed to the PCB and covering the image sensor, a lens barrel coupled to the lens holder, and a lens received in the lens barrel. The lens holder includes an inner sensor cover and an outer sensor cover surrounding the inner sensor cover. The image sensor, the inner sensor cover, the lens barrel and the lens define an enclosed space. The inner sensor cover and the outer sensor cover define an intermediate space. The inner sensor cover defines an inner dissipation hole communicating the enclosed space with the intermediate space. The outer sensor cover defines an outer dissipation hole that communicates the intermediate space with the outside of the outer sensor cover. The inner dissipation hole and the outer dissipation hole are misaligned to prevent the ingress of light and dust.

Camera module facilitating heat dissipation

A camera module includes an image sensor, a substrate, a lens part, a lens holder, and a voice-coil motor (VCM). The image sensor is supported on and electrically connected to the substrate. The lens holder has a bottom end and an upper end opposite to the bottom end. The image sensor is accommodated within the lens holder. The lens part includes a lens barrel which has an upper portion and a bottom portion and is disposed on the lens holder. The VCM includes a winding coiling around the upper portion and a set of permanent magnetic members fixedly fixed and surrounding the winding. The outer diameter of the upper portion is smaller than that of the bottom portion. The VCM is configured for driving the lens part to move toward to or away from the image sensor.

Camera module having voice-coil motor

An exemplary objective holder for engaging with a PCB substrate having an image sensor and several passive components arranged thereon, includes a base and several continuously connected walls extending from the base. The walls enclose a chamber thereamong for receiving the image sensor and define notches therein for receiving the passive components.

Objective holder for camera module with notches of wall receiving passing components

An exemplary objective holder engages with a PCB substrate having an image sensor and several passive components arranged thereon. The passive components surround the image sensor. The objective includes a lens barrel extending from a side of a base, and a plurality of walls extending from an opposite side of the base. The walls enclose a chamber thereamong for receiving the image sensor and define notches therein for receiving the passive components therein. A transparent cover is received in the objective holder between the lens barrel and the chamber. An adhesive is used to connect the objective holder to the PCB substrate. The PCB substrate is rested on the walls. At least one of the notches communicates the chamber to an exterior for outgassing and is sealed by a mass of sealing material after a heating process of the adhesive.
