Abstract
The electromagnetic interference(EMI)has a strong impact on the technology performance of sealed terminal.The elec⁃tromagnetic shielding is one of the important measures of raising electromagnetic compatibility of electronic system and electronic equip⁃ment.This paper introduces briefly the structure of a typical sealed communication terminal,analyzes the problems in electromagnetic shielding design of sealed communication terminals,and also points out the leak source that impacts the electromagnetic shielding effi⁃ciency of terminals.Taking a typical sealed communication terminal as an example,the electromagnetic shielding design is performed aiming at different structural characteristics of connector,switch,indicator hole,screen,keyboard interface,power connector and switch without sealing capability changing and reducing,and the typical design idea and method are proposed.The electromagnetic compatibility test results show that this design method is scientific and available.关键词
