Abstract

An electronic device is provided. The electronic device includes a housing having a base plate and a sidewall, the sidewall having a shape bent and extended from an end of the base plate, a duct in the base plate that is parallel to a surface of the base plate and having an external end open to the sidewall of the housing, an electronic part placed on an internal surface of the base plate to cover at least a portion of the duct, and a waterproof sheet disposed between the duct and the electronic part to protect the electronic part.

First claim

What is claimed is:

1. An electronic device comprising:
a housing having a base plate and a sidewall, the sidewall having a shape bent and extended from an end of the base plate;
a duct in the base plate that is parallel to a surface of the base plate and having an external end open to the sidewall of the housing;
an electronic part placed on an internal surface of the base plate to cover at least a portion of the duct; and
a waterproof sheet disposed between the duct and the electronic part to protect the electronic part.

2. The electronic device according to claim 1 , wherein the duct includes a section having a valley shape recessed from the internal surface of the base plate.

3. The electronic device according to claim 2 , wherein the duct includes a slope decreasing toward the external end of the duct.

4. The electronic device according to claim 2 , wherein a cross-sectional area of the external end of the duct is wider than remaining sections of the duct.

5. The electronic device according to claim 2 , further comprising a dustproof sheet disposed between the duct and the waterproof sheet to protect the electronic part from a foreign material entering through the external end of the duct.

6. The electronic device according to claim 5 , wherein the dustproof sheet covers the duct without a contact with a surface of the duct.

7. The electronic device according to claim 6 , wherein the dustproof sheet covers an entire section of the duct.

8. The electronic device according to claim 6 , wherein the waterproof sheet covers an entire region of the dustproof sheet.

9. The electronic device according to claim 1 , wherein a placement guide for guiding the electronic part to a desired location for fastening is disposed near the duct on the internal surface of the housing.

10. The electronic device according to claim 9 , wherein the placement guide has a barrier surrounding a lateral face of the electronic part, the barrier being open near the external end of the duct.

11. The electronic device according to claim 6 , wherein a face on which the waterproof sheet is disposed is more recessed than a face on which the dustproof sheet is disposed, and the surface of the duct is more recessed than the face on which the dustproof sheet is disposed.

12. The electronic device according to claim 2 , further comprising a filler disposed between the electronic part and the sidewall of the housing.

13. The electronic device according to claim 12 , wherein at least a section near the duct on a connection between the base plate and the sidewall forms a first curved surface.

14. The electronic device according to claim 13 , wherein a surface facing the first curved surface among surfaces of the filler is formed as a second curved surface having a shape corresponding to the first curved surface.

15. The electronic device according to claim 14 ,
wherein the waterproof sheet covers the first curved surface, and
wherein the second curved surface of the filler contacts the waterproof sheet.

16. The electronic device according to claim 15 , further comprising a pressing member for pressing the filler toward the first curved surface.

17. The electronic device according to claim 16 , wherein the pressing member is disposed on an opposite surface to a surface facing the base plate among opposite surfaces of the electronic part.

18. The electronic device according to claim 17 , wherein the pressing member is a printed circuit board (PCB) installed in the electronic device.

19. The electronic device according to claim 1 , wherein the housing has a communication hole branched from the duct and communicating with the surface of the base plate.

20. The electronic device according to claim 5 , wherein an attachment region is provided on a perimeter of the waterproof sheet.

21. The electronic device according to claim 20 , wherein the attachment region is formed on opposite surfaces of the waterproof sheet.

22. The electronic device according to claim 21 , wherein a space is formed between a central portion of a lateral face of the base plate of the electronic part and the waterproof sheet.

23. The electronic device according to claim 1 , further comprising a dustproof sheet disposed between the duct and the waterproof sheet to protect the electronic part from a foreign material entering through the external end of the duct.

24. The electronic device according to claim 23 , wherein the electronic part has an input and output element for receiving data on at least one of temperature, humidity and wave from an outside or outputting the data to the outside, and
wherein the data enters the duct in the parallel direction to the surface of the base plate through the external end of the duct and then is bent away from the surface of the base plate to be input to the input and output element through the dustproof sheet and the waterproof sheet.

25. The electronic device according to claim 23 , wherein the electronic part has an input and output element receiving data on at least one of temperature, humidity and wave from an outside or outputting the data to the outside, and
wherein the wave output from the input and output element enters the duct through the waterproof sheet and the dustproof sheet and is bent in the parallel direction to the surface of the base plate to be output to the outside through the external end of the duct.

26. An electronic device comprising:
a housing having a base plate and a sidewall, the sidewall having a shape bent and extended from an end of the base plate;
an electronic part having an input and output element for receiving data on at least one of temperature, humidity and wave from an outside or outputting the data to the outside, wherein the input and output element is disposed to face an internal surface of the base plate;
a duct in the housing having a shape recessed toward a surface of the base plate while facing the input and output element, and having an external end open toward a sidewall of the housing; and
a waterproof sheet disposed between the electronic part and the duct, covering a surface of the duct facing the input and output element.
