Abstract

A camera module is provided with a lens part including a lens and a lens barrel, a holder coupled with the lens part and formed with a first conductive layer, and a printed circuit board electrically connected to the first conductive layer while supporting the holder.

Claims

1. A camera module comprising:

a sensor part comprising a lens part comprising a lens and a lens barrel, a holder coupled with the lens part, a first printed circuit board disposed with an image sensor while supporting the holder, and a first conductive layer formed on the first printed circuit board;

a second printed circuit board connected to the sensor part; and

a connector connected to the second printed circuit board,

wherein the second printed circuit board is a flexible printed circuit board and comprises a second conductive layer, and the connector comprises a third conductive layer,

wherein the first printed circuit board extends under the holder.

2. The camera module according to claim 1, wherein a grounding area is formed at least one of the first printed circuit board, the second printed circuit board and the connector.

3. The camera module according to claim 1, wherein at least one of the conductive layers is electrically grounded.

4. A camera module comprising:

a lens part comprising a lens, a lens barrel, and an actuator;

a holder coupled with the lens part, in which a first conductive layer is formed on a surface of the holder;

a printed circuit board electrically connected to the first conductive layer while supporting the holder;

a boss pin integrally formed with the holder at a lower portion of the holder, wherein the boss pin is coupled with the printed circuit board to fix the holder to the printed circuit board; and

a second conductive layer formed on a surface of the boss pin.

5. The camera module according to claim 4, comprising a third conductive layer formed on the lens part.

6. The camera module according to claim 4, comprising a grounding area electrically connected to the first conductive layer, and formed on the printed circuit board.

7. The camera module according to claim 6, wherein the grounding area is not formed with solder resist.

8. The camera module according to claim 4, comprising a cap formed at an outer portion of both the lens part and the holder.

9. The camera module according to claim 8, comprising a socket disposed at a lower portion of the printed circuit board, and coupled with the cap to support the cap.

10. The camera module according to claim 8, wherein a groove is formed in at least a portion of the holder, and a protrusion is formed in at least a portion of the cap corresponding to the groove.

11. The camera module according to claim 4, comprising a fourth conductive layer formed at a lower portion of the printed circuit board.

12. A camera module comprising:

a lens part comprising a lens and a lens barrel;

a holder coupled with the lens part and provided with an IR blocking filter;

a printed circuit board supporting the holder; and

a cap including a conductive material and configured to surround outer surfaces of the lens part and the holder,

wherein a first side surface of the holder faces a second side surface of the cap, wherein one of the first side surface and the second side surface includes a protrusion and the other of the first side surface and the second side surface includes a groove, and

wherein the cap is coupled to the outer surface of the holder by the protrusion inserted into the groove.

13. The camera module according to claim 12, wherein the protrusion is formed on the cap.

14. The camera module according to claim 12, wherein the protrusion is provided in plural.

15. The camera module according to claim 12, wherein one of the lens part and the holder includes a conductive material on outer peripheral surface.

16. The camera module according to claim 15, wherein the printed circuit board includes a grounding hole and the holder includes a boss pin, wherein the boss pin is inserted into the grounding hole and the conductive material is grounded.

17. The camera module according to claim 12, wherein the holder is coupled to the printed circuit board through a conductive epoxy.
