Patent ID: 7978283

Claim:
A shielding structure of thin type monitor device comprising: a monitor body having a first metal plate that is grounded; a first shielding box, which is formed by cutting and bending a second metal plate arranged inside of the monitor body, and fixed on the first metal plate in the monitor body; a terminal holder, arranged to contact the first shielding box, and formed as a part of a case of the monitor body; and a second shielding box, which is formed by cutting and bending a third metal plate, wherein the first shielding box includes: a flat plate portion having rectangular shape; and a terminal supporting portion which is formed by bending one short side of the flat plate portion such that a terminal can pass through, in which a substrate on which the terminal is mounted is held to be parallel with the flat plate portion, and a process circuit board performing signal processing is fixed on a part close to the terminal supporting portion in the flat plate portion; the terminal holder includes: a terminal hole contacting an opposite side of the terminal supporting portion with respect to the flat plate portion, and configured for the terminal to pass through; the second shielding box includes: a protecting portion which has a rectangular shape and is arranged such that it contacts the terminal supporting portion and is parallel to the flat plate portion; and a standing portion which is formed by bending three sides of the protecting portion that do not contact the terminal supporting portion, and is configured to contact the flat plate portion; a through hole having a rectangular shape formed on the terminal supporting portion; a fixing rib formed by bending a part of a side in the protecting portion that contacts the terminal supporting portion, is formed on the second shielding box; the fixing rib passes through the through hole in the terminal supporting portion and contacts a peripheral portion of the through hole, wherein the fixing rib is pressed down by the terminal holder, and the fixing rib is consequently contacted the terminal supporting portion; and a pressing rib formed to press the fixing rib on a part of the terminal holder which contacts the fixing rib.
