Abstract:
1. An electromagnetic shielding device comprising: a first plate having two edges, each of which is formed with pluralities of first and second plate sections that are disposed alternately along a respective edge thereof, each of the first plate sections having a first segment extending from the respective edge of the first metal plate, a second segment offsetting from the first segment, and an intermediate segment interconnecting the first segment and the second segment, each of the second plate sections having two opposite side faces, a bottom recess and an upper protrusive block that is disposed at an elevation higher than the bottom recess and that is formed on one of the opposite side faces; and a second plate detachably connected to the first plate, and having two edges, each of which is formed with pluralities of third and fourth plate sections that are disposed alternately along a respective edge thereof, each of the third plate sections having two opposite side faces, an upper recess and a lower protrusive block that is disposed at an elevation lower than the upper recess and that is formed on one of the opposite side faces, each of the fourth plate sections having a lower vertical segment extending upwardly from the respective edge of the second plate, an upper vertical segment offsetting from the lower vertical segment, and an intermediate segment interconnecting the lower vertical segment and the upper vertical segment; whereby, once assembled, the intermediate segment of a respective one of the first plate sections in the first plate is seated on the upper recess of a respective one of the third plate sections in the second plate while the second segment of the respective one of the first plate sections in the first plate is supported by the lower protrusive block of a respective one of the third plate sections in the second plate and that the intermediate segment of a respective one of the fourth plate sections in the second plate supports the bottom recess of a respective one of the second plate sections in the first plate while the upper protrusive block of the respective one of the second plate sections in the first plate is supported by the upper vertical segment of the respective one of the fourth plate sections in the second plate.
