Abstract

The invention is a shielded protection device in wireless local network card, it includes protective pedestal and protective cover, the pedestal is set on the circuit board of the card and it includes the body and the frame. The frame is set at sides and it has protuberant thing. The cover includes the body and the ouches, the ouches are set at sides of the cover. The ouches have hole and clamp, the fasting hole is between the clamp and the cover. It is used to connect with the protuberant thing. The clamp wedges the protuberant thing. In this design, the pressure of the pedestal and the cover increases and the resistance is decreased, in order to avoid the leakage of electromagnetism wave.

Description

technical field [0001] The invention relates to a shielding device, in particular to a shielding protection device used on a wireless area network card. Background technique [0002] In today's era of rapid technological development, portable electronic products have become an indispensable part of modern life, and portable electronic products such as notebook computers (notebooks), mobile phones (cellular phones) and personal digital assistants (personal digital assistants) , PDA) etc. [0003] Coupled with the rapid development of the Internet, portable electronic products can be configured with a wireless LAN card, such as a mini peripheral component interconnect (Mini PCI) wireless LAN card. It is very convenient for modern people to connect to the Internet through portable electronic products anytime and anywhere, so as to browse websites and search for required information. [0004] Wherein, the wireless local area network card usually has a...
