Abstract

A holder for a camera module includes first and second surfaces, an optical filter receiving groove is recessed from the first surface to the second surface to form a step portion and a glue receiving portions extend from angled abutments of the step portion. A sensor receiving groove is recessed from the second surface to the first surface, and the sensor receiving groove communicates with the optical filter receiving groove. At least one escape passage is defined in the holder, the at least one escape passage communicates with the optical filter receiving groove and the sensor receiving groove. The at least one escape passage abuts the glue receiving portions and provides an escape path for captured moisture and gases expanding or shrinking because of temperature variations.

Claims

1. A holder for camera module comprising:

a first surface and a second surface opposite to the first surface, an optical filter receiving groove recessed from the first surface to the second surface to form a step portion and glue receiving portions extending from angled abutments of the step portion;

a sensor receiving groove recessed from the second surface to the first surface, and the sensor receiving groove communicating with the optical filter receiving groove; and

at least one escape passage defined in the holder, wherein the at least one escape passage communicates with the optical filter receiving groove and the sensor receiving groove;

the at least one escape passage abutting the glue receiving portions.

2. The holder of claim 1, wherein the step portion is configured for an optical filter to be attached thereon, the holder further comprises a dustproof glue, the dustproof glue is applied between the optical filter and a side wall of the optical filter receiving groove.

3. The holder of claim 2, wherein the sensor receiving groove communicates with the optical filter receiving groove by a first through hole.

4. The holder of claim 3, wherein a depth of the escape passage is greater than a sum of a depth of the first through hole and a thickness of the dustproof glue.

5. The holder of claim 1, wherein the at least one escape passage communicates with the optical filter receiving groove by a second through hole.

6. The holder of claim 1, wherein a step groove is recessed from the first surface to the second surface, the step groove abuts on the peripheral edge of the holder.

7. The holder of claim 6, wherein the optical filter receiving groove is recessed from a bottom of the step groove to the second surface.

8. A camera module, comprising:
