Abstract

An optical module comprising an upper portion of the housing with a bottom and two sides, a lower portion of the housing with a bottom and two sides, an electric component and an electroconductive sheet is provided. The two sides of the upper portion may be inserted between the two sides of the lower portion to form a relatively closed cavity for accommodating the electric component. A first convex block provided on the sides of the upper portion may be inserted into a gap which is formed between a second convex block and a third convex block provided on the sides of the lower portion. Thus, the first convex block, the second convex block and the third convex block may clamp the electroconductive sheet, thereby dividing the gap at the junction of the upper portion and the lower portion into a plurality of tiny gaps.

First claim

What is claimed is:

1. An optical module, comprising:
a housing comprising a lower portion and an upper portion;
the upper portion of the housing comprising a bottom and two sides defining a U-shape;
the lower portion of the housing comprising a bottom and two sides defining a U-shape, the two sides of the upper portion being inserted between the two sides of the lower portion to form a cavity, wherein:
at least one first convex block is disposed on an outer surface of each of the two sides of the upper portion of the housing, and is configured to face one of the two sides of the lower portion of the housing,
at least one second convex block and at least one third convex block are disposed on an inner surface of each of the two sides of the lower portion of the housing, and are configured to face one of the two sides of the upper portion of the housing, and
the at least one first convex block is inserted into a gap between the at least one second convex block and the at least one third convex block;

an electro-conductive sheet disposed between the at least one first convex block, the at least one second convex block and the at least one third convex block; and
at least one electric component disposed inside the cavity.

2. The optical module of claim 1 , wherein:
the upper portion of the housing, the lower portion of the housing, the first convex block, the second convex block and the third convex block comprise electrical conductive material.

3. An optical module, comprising:
a housing comprising a lower portion and an upper portion;
the upper portion of the housing comprising a bottom and two sides defining a U-shape;
the lower portion of the housing comprising a bottom and two sides defining a U-shape, the two sides of the upper portion being inserted between the two sides of the lower portion to form a cavity, wherein:
at least one first convex block is disposed on an outer surface of each of the two sides of the upper portion of the housing, and is configured to face one of the two sides of the lower portion of the housing,
at least one second convex block and at least one third convex block are disposed on an inner surface of each of the two sides of the lower portion of the housing, and are configured to face one of the two sides of the upper portion of the housing, and
the at least one first convex block is inserted into a gap between the at least one second convex block and the at least one third convex block;

an electro-conductive sheet disposed between the at least one first convex block, the at least one second convex block and the at least one third convex block;

a distance between two adjacent second and third convex blocks is smaller than one twentieth of the wavelength of the electromagnetic waves generated by the at least one electric component.

4. The optical module of claim 3 , wherein:
a size that the at least one first convex block protrudes toward the faced side of the two sides of the lower portion of the housing is smaller than a distance between a side of the two sides of the upper portion of the housing on which the at least one first convex block is disposed and the faced side of the two sides of the lower portion of the housing; and
a size that each of the at least one second convex block and the at least one third convex block protrudes toward the faced side of the two sides of the upper portion of the housing is smaller than a distance between a side of the two sides of the lower portion of the housing on which the at least one second convex block and the at least one third convex block are disposed and the faced side of the two sides of the upper portion of the housing.

5. The optical module of claim 1 , wherein:
the at least one first convex block, the at least one second convex block and the at least one third convex block comprise elastic vertical ribs.

6. The optical module of claim 5 , wherein
the elastic vertical ribs are sloped; and
an angle of slope of the elastic vertical ribs are same.

7. The optical module of claim 1 , wherein:
the upper portion of the housing further comprises an upper partition perpendicular to the two sides of the upper portion of the housing and the bottom of the upper portion of the housing;
the lower portion of the housing further comprises a lower partition perpendicular to the two sides of the lower portion of the housing and the bottom of the lower portion of the housing;
at least one fourth convex block is disposed on the upper partition, and configured to face the lower partition;

the at least one fourth convex block, the at least one fifth convex block and the at least one sixth convex block clamp the electro-conductive sheet.

8. The optical module of claim 7 , wherein:
a number of the at least one fourth convex block is larger than one;
a distance between two adjacent fourth convex blocks is smaller than one twentieth of a wavelength of electromagnetic waves generated by the at least one electric component; and
a distance between two adjacent fifth and sixth convex blocks is smaller than one twentieth of the wavelength of the electromagnetic waves generated by the at least one electric component.

9. The optical module of claim 7 , wherein:
the fourth convex block, the fifth convex block and the sixth convex block comprise elastic vertical ribs.

10. The optical module of claim 1 , wherein
the bottom of the upper portion of the housing has a protruding section relative to each of the two sides of the upper portion of the housing; and
the protruding section is configured to cover the two sides of the lower portion of the housing in a thickness direction.

11. An optical module, comprising:
