US 7,254,042 B2 · Electro magnetic interference shielding device and a liquid crystal display device adopting same

Abstract

An Electro Magnetic Interference (EMI) shielding device (20) includes a body (201), at least a first engaging portion (203) extending from the body, and a pair of second engaging portions (205) formed on the body. A liquid crystal display device adopting the above mentioned EMI shielding device includes a TFT LCD panel, a power supply (12), an inverter (14) and an interface board (13). The power supply, the inverter and the interface board are formed on a printed circuit board (10). The EMI shielding device is positioned between the power supply and the inverter, with the first engaging portion inserted into the printed circuit board and the second engaging portions engaging with the printed circuit board. The EMI shielding device can reduce or potentially avoid the occurrence of EMI that would otherwise be produced by the printed circuit board.

Dependent claims

An Electro Magnetic Interference (EMI) shielding device, comprising:

a body sized and configured for at least reducing an amount of electro magnetic interference that could potentially be generated by proximate components on a printed circuit board;
at least a first engaging portion extending from and being spatially coplanar with the body, each first engaging portion being configured for insertion into the printed circuit board and engagement therewith;
and
a pair of second engaging portions extending from the body along a direction approximately perpendicular to the body, the second engaging portions and each first engaging portion being formed at a same side of the body.
