Electromagnetic radiation suppression device and its electronic equipment

Abstract

The invention relates to an electromagnetic radiation restraining device and an electronic device thereof. The electromagnetic radiation restraining device comprises a wire which is provided with a shielding layer, the electromagnetic radiation restraining device further comprises a fixing and grounding assembly which comprises a fixing end and a wrapping portion, the wrapping portion is wrapped on the outside of the shielding layer of the wire, and the fixing end is used for fixing and locking the wire. According to the electromagnetic radiation restraining device and the electronic device thereof, due to the fact that the fixing and grounding assembly is arranged, the shielding layer of the wire is tightly wrapped through the wrapping portion and fixed on a metal box of the electronic device through the fixing end; on one hand, the wire is fastened to the electronic device; on the other hand, the wire is fully grounded, and the overall electromagnetic shielding effect of the wire and the electronic device is further improved.

Description

technical field [0001] The invention relates to the field of electromagnetic radiation design, in particular to an electromagnetic radiation suppression device and electronic equipment thereof. Background technique [0002] The use environment of electronic equipment (such as portable ruggedized computers) in some special application fields is getting worse and worse, and the requirements for electromagnetic interference are also getting higher and higher. Conventional hardened computers need to meet GB 9254-2008 radio disturbance limits and measurement methods for information technology equipment. In harsher military environments, they need to meet GJB 151A-1997: Military equipment and subsystem electromagnetic emission and sensitivity requirements. [0003] There are two key points in the electromagnetic shielding design of electronic equipment. One is to ensure the conductive continuity of the shielding body, that is, the entire shielding body must be a complete and conti...

Problems solved by technology

[0004] For portable reinforced computers, in the prior art, since the shielding layer and conductive cloth of the LVDS wire of the LCD display do not extend to the connector end, a complete fully enclosed shielding cannot be achieved, and most of the shielding layers of the connectors at both ends pass through the conductive cloth. Pasted on the metal surface, due to the inherent characteristics of the conductive cloth, it is easy to lose its viscosity after a long time, and it is easy to fall off, which cannot meet the requirements of good conductivity

As for the keyboard cable that needs to pass through the chassis shell, the position of the opening is to allow the port of the keyboard cable to pass through. To be 100% consistent, the shielding layer of the keyboard wire cannot have a good conductive contact with the edge of the opening, which may easily cause leakage of electromagnetic radiation
