Specific embodiment
For the enabled content for having a clear understanding of the utility model, it is illustrated with the following example collocation schema and symbol,
It please be refering to.
Shown in please referring to Fig.1 to Fig.3, the utility model provides a kind of electromagnetic wave interference shielding device, it includes: a framework 1
With a lid 2.
Wherein, which has an accommodating space 10, and the horizontal plane in the framework 1 its to accommodating space
10 positions, which extend, is equipped with plural engaging portion 11 (such as Fig. 1, Fig. 3), and each engaging portion 11 is each extended over equipped with a bending part 12, often
One bending part 12 is each extended over equipped with one second engaging portion 13, and the setting of each bending part 12 makes the respectively engaging portion 11 and
