Abstract

A camera module, according to an embodiment of the present invention, comprises: a printed circuit board, on which an image sensor is mounted; a lens barrel installed on the printed circuit board and having at least one lens installed therein; an actuator module which is assembled in the lens barrel and includes first and second actuators having first and second moving lenses, respectively, installed therein, wherein the first and second moving lenses respectively perform and auto focusing function on an image formed at the image sensor and an image stabilization function; and a connector which is formed in the lens barrel and connected to the actuator module such that electricity can flow therebetween.

First claim

What is claimed is:

1. A camera module, comprising:
a main printed circuit board mounted with an image sensor;
a lens barrel disposed at an upper side of the main printed circuit board and installed with at least one lens;
an actuator module disposed at an upper side of the lens barrel and comprising first and second actuators respectively installed with first and second moving lenses configured to respectively perform an auto focusing function and a handshake compensation function for an image formed on the image sensor;
a first printed circuit board coupled with the first actuator and the main printed circuit board; and
a second printed circuit board coupled with the second actuator and the main printed circuit board.

2. The camera module of claim 1 , wherein the first and the second moving lenses are assembled after an assembly process of the first and the second actuators.

3. The camera module of claim 1 ,
further comprising a connection portion formed at the lens barrel; and
wherein one side end portion of the first and the second printed circuit boards is conductibly connected to the connection portion.

4. The camera module of claim 3 , wherein the first and the second moving lenses are assembled at the first and the second actuators before an assembly process of first and second support portions.

5. The camera module of claim 3 , wherein the first and the second moving lenses are assembled at the first and the second actuators after an assembly process of first and second support portions.

6. The camera module of claim 3 , wherein the first printed circuit board is packaged at a first support portion, the second printed circuit board is packaged at a second support portion, and a third support portion corresponding to the first support portion is provided at an upper side surface of the first printed circuit board to support the first actuator.

7. The camera module of claim 3 , wherein the first printed circuit board is packaged at a first support portion, the second printed circuit board is packaged at a second support portion, and a third support portion corresponding to the first support portion is provided at an upper side surface of the first printed circuit board to support the first actuator, and
the first to the third support portions, each size corresponding to the other, are coupled all at once.

8. The camera module of claim 3 , wherein the first and the second printed circuit boards are formed of F-PCB.

9. The camera module of claim 3 , further comprising:
a plurality of first beads and second beads interposed at a connection portion between the first and the second printed circuit boards and the first and the second actuators,
wherein the first and the second beads are arranged at a position not interfering with each other.

10. The camera module of claim 3 , wherein one end of the connection portion is conductibly connected to the actuator module and another end of the connection portion is conductibly connected to the main printed circuit board.

11. A camera module, comprising:
a main printed circuit board mounted with an image sensor;
a lens barrel disposed at an upper side of the main printed circuit board and mounted with at least one lens;
an actuator module disposed at an upper side of the lens barrel and comprising first and second actuators respectively installed with first and second moving lenses configured to respectively perform an auto focusing function and a handshake compensation function for an image formed on the image sensor; and
a module printed circuit board coupled with the actuator module and the main printed circuit board;
wherein the first actuator is coupled on an upper surface of the module printed circuit board, and the second actuator is coupled on a bottom surface of the module printed circuit board.

12. The camera module of claim 11 , wherein the first and the second moving lenses are assembled after an assembly process of a module actuator comprising the first and second actuators.

13. The camera module of claim 11 , further comprising a housing member supporting both ends of a module actuator comprising the first and second actuators; and
a connection portion formed at the lens barrel and electrically connected with the actuator module,
wherein one side end portion of the module printed circuit board is conductibly connected to the connection portion.

14. The camera module of claim 13 , wherein the first and the second moving lenses are assembled at the actuator module after an assembly process of the housing member.

15. The camera module of claim 13 , wherein the module printed circuit board is formed of F-PCB.

16. The camera module of claim 11 , further comprising:
a plurality of first beads and second beads interposed at a connection portion between the module printed circuit board and first and second actuators,
wherein the first and the second beads are arranged at a position not interfering with each other.

17. The camera module of claim 13 , wherein one end of the connection portion is conductibly connected to the actuator module and another end of the connection portion is conductibly connected to the main printed circuit board.
