Abstract
The invention discloses a wireless network device with an electromagnetic interference shielding function. A first groove is opened in the wireless network device; the bottom part of the first grooveis provided with a second groove; the second groove is internally provided with a USB interface female head; the inner wall and the bottom part of the first groove are both made of an electromagneticshielding material or coated with an electromagnetic shielding coating; and the bottom part of the second groove is made of the electromagnetic shielding material or coated with the electromagnetic shielding coating. Anti-electromagnetic interference improvement is made on the wireless network device, the wireless network device can perform electromagnetic interference resistance on USB peripherals which do not have a good electromagnetic shielding function, the wireless network device, after a U disc is connected, can perform electromagnetic shielding, and interference to the wireless networkdevice is reduced.
Description
technical field [0001] The invention relates to the field of electromagnetic shielding, in particular to a wireless network device with electromagnetic interference shielding function. Background technique [0002] Nowadays, multifunctional integration of home network equipment is already a trend. On some multi-functional network devices, in order to meet the needs of home users for network file services, and to achieve a balance between access speed, ease of use and cost, USB3.0 (a USB standard specification) interface is usually selected. As an external storage interface, it is convenient for users to connect their USB storage to network file services. The USB3.0 interface will inevitably radiate broadband electromagnetic waves to the surroundings when transmitting data, and its peak spectrum even covers the frequency range of all 2.4GHz channels specified by IEEE802.11 (a general standard for wireless local area networks). The 2.4GHz band for wireless networking happens...
