Abstract

A PCB assembly includes a panel including at least one guide protrusion, at least one mounting portion, and at least one dislocation prevention protrusion, and a PCB including at least one guide hole formed to correspond to the at least one guide protrusion, at least one grounding portion formed to correspond to the at least one mounting portion, and at least one dislocation prevention hole formed to correspond to the at least one dislocation prevention protrusion, wherein the PCB is guided to slide by the at least one guide protrusion and the at least one guide hole, is brought into close contact with the panel by the at least one mounting portion and the at least one grounding portion, and fixed to the panel as the at least one dislocation prevention hole is supported by the at least one dislocation prevention protrusion.

First claim

What is claimed is:

1. A printed circuit board (PCB) assembly comprising:
a panel comprising a guide protrusion, a mounting portion, and a dislocation prevention protrusion having an inclined plane and being spaced apart from the guide protrusion and the mounting portion; and
a PCB comprising a guide hole formed to correspond to the guide protrusion, a grounding portion formed to correspond to the mounting portion, and a dislocation prevention hole formed to correspond to the dislocation prevention protrusion,
wherein the guide protrusion is slidable in the guide hole to guide a sliding movement of the PCB so that the PCB becomes coupled to the mounting portion, the grounding portion becomes connected to the mounting portion, and the PCB slides along the inclined plane of the dislocation prevention protrusion to cause the dislocation prevention hole to become coupled to the dislocation prevention protrusion to prevent the PCB from being separated from the panel.

2. The PCB assembly of claim 1 , wherein the coupling of the PCB to the mounting portion fixes the PCB to the panel, and the connecting of the grounding portion to the mounting portion is to electrically ground the PCB to the panel.

3. The PCB assembly of claim 1 , wherein the guide hole and the guide protrusion provide for a horizontal sliding movement of the PCB.

4. The PCB assembly of claim 3 , wherein
the PCB has a first region on which an electronic component is mounted, and a second region other than the first region,
the guide hole is formed at an upper portion or a lower portion of the second region, and
the guide protrusion is formed in the panel on a position corresponding to the guide hole.

5. The PCB assembly of claim 4 , wherein the guide hole is located at an upper portion or a lower portion of the second region in a diagonal direction to prevent rotational movement of the PCB.

6. The PCB assembly of claim 4 , wherein
the grounding portion is formed at the second region, and
the mounting portion is formed in the panel at a position corresponding to the grounding portion.

7. The PCB assembly of claim 1 , wherein the mounting portion comprises:
an open surface formed to be open to allow the PCB to be inserted into the mounting portion,
a fixing surface provided to hold the PCB inserted into the mounting portion, and
two support surfaces extending from the fixing surface to be perpendicular to the fixing surface and provided to support the PCB inserted into the mounting portion.

8. The PCB assembly of claim 7 , wherein the mounting portion comprises a guide extending from the fixing surface to guide insertion of the PCB.

9. The PCB assembly of claim 8 , wherein the guide is formed to be inclined downward in a sliding direction of the PCB.

10. The PCB assembly of claim 1 , wherein
the dislocation prevention protrusion comprises a stopper, and
the stopper is accommodatable in the dislocation prevention hole to prevent the PCB from moving when the PCB becomes coupled to the mounting portion.

11. The PCB assembly of claim 1 , wherein the inclined plane is formed to be inclined upward in a sliding direction of the PCB.

12. An electronic appliance comprising:
a panel; and
a printed circuit board (PCB) mounted on the panel, wherein
the panel comprises a guide protrusion, a mounting portion, and a dislocation prevention protrusion having an inclined plane and being spaced apart from the guide protrusion and the mounting portion, and
the PCB comprises a guide hole formed to correspond to the guide protrusion, a grounding portion formed to correspond to the mounting portion, and a dislocation prevention hole formed to correspond to the dislocation prevention protrusion,
the PCB and the panel thereby being configured so that, to mount the PCB on the panel, the guide protrusion is slidable in the guide hole to guide a sliding movement of the PCB so that the PCB becomes coupled to the mounting portion, the grounding portion becomes connected to the mounting portion, and the PCB slides along the inclined plane of the dislocation prevention protrusion to cause the dislocation prevention hole to become coupled to the dislocation prevention protrusion to prevent the PCB from being separated from the panel.

13. The electronic appliance of claim 12 , wherein the guide hole and the guide protrusion provide for a horizontal sliding movement of the PCB.

14. The electronic appliance of claim 12 , wherein the guide hole is located at an upper portion or a lower portion of the PCB in a diagonal direction to prevent rotational movement of the PCB.

15. The electronic appliance of claim 12 , wherein
electronic components are mounted on the PCB,
the grounding portion is formed on the PCB where an electronic component is not mounted, and
the mounting portion is formed in the panel at a position corresponding to the grounding portion.

16. The electronic appliance of claim 12 , wherein the mounting portion comprises:
an open surface formed to be open to allow the PCB to be inserted into the mounting portion,
a fixing surface provided to hold the PCB inserted into the mounting portion, and
two support surfaces extending from the fixing surface to be perpendicular to the fixing surface and provided to support the PCB inserted into the mounting portion.

17. The electronic appliance of claim 16 , wherein the mounting portion comprises a guide extending from the fixing surface to be inclined downward in a sliding direction of the PCB to guide insertion of the PCB.

18. The electronic appliance of claim 12 , wherein
the dislocation prevention protrusion comprises a stopper, and,
with the PCB mounted on the panel, the stopper is accommodated in the dislocation prevention hole to prevent the PCB from moving.

19. A printed circuit board (PCB) assembly comprising:
a panel comprising a guide protrusion, a mounting portion, and a dislocation prevention protrusion having an inclined plane and being spaced apart from the guide protrusion and the mounting portion; and
a PCB comprising a guide hole, a grounding portion, and a dislocation prevention hole,
wherein the guide protrusion is slidable in the guide hole to guide a sliding movement of the PCB so that the PCB becomes coupled to the mounting portion to fix the PCB to the panel, the grounding portion becomes connected to the mounting portion to electrically ground the PCB to the panel, and the PCB slides along the inclined plane of the dislocation prevention protrusion to cause the dislocation prevention hole to become coupled to the dislocation prevention protrusion to prevent dislocation or separation of the PCB from the panel.
