Electromagnetic interference shield assemblies

Abstract

The assembly includes the U-shaped component and the elastic component mainly. The U-shaped component embedded into the chassis of the electric device is utilized for fixed connecting the electromagnetic interference shield assembly to the electric appliances. The elastic component is utilized for shielding the electromagentic interference to the electric appliances. The elastic component is connected to the bottom plate of the U-shaped component and extended between the two side walls toward the opening part of the U-shaped component and protruding out of the chassis of the electric appliances.

Description

technical field [0001] The invention relates to an electromagnetic wave isolation device, in particular to an anti-electromagnetic interference device applied to electronic products and used to shield electromagnetic waves. Background technique [0002] In recent years, the electronic information industry has developed vigorously, especially the use of various electronic information products is becoming more and more common. Under the development trend of electronic information products shrinking in size, there are unnecessary voltages or currents between internal systems, which generate a lot of broadband noise , which seriously affects the functions of each device, and this phenomenon is generally called Electromagnetic Interference (EMI for short). Among them, the EMI problem in the computer manufacturing industry is quite complicated, and its interference sources include microprocessors (CPU), motors, commutators, relays, switches, transistors, a...

[0005] However, there are also some defects in the use of conductive foam. For example, when information electronics products must be joined or tightly sealed (such as between the upper and lower casings), there are often gaps because they cannot be tightly bonded. When strengthening the isolation effect of electromagnetic waves at this joint, it is impossible to directly attach the conductive foam to the outside of the joint between the upper and lower casings because of its certain thickness, so as to reinforce the effect of isolating electromagnetic interference.

However, the foregoing will also be damaged when the upper and lower casings are opened, and new conductive foam must be attached again, which makes it very inappropriate to attach the conductive foam to the junction of the upper and lower casings.
