Adapting card with electromagnetic interference protection

The utility model discloses an EMI shielding adapter card comprising: a main body which includes a circuit board and an electron component assembled on the circuit board; a common place mounted on said main body and coupling with said electron component; a fixture disposed one edge of said main body and connecting to said common place with electricity; a support set on the edge of said main body and connecting to said fixture with electricity, inwhich the ground line of said electron component connects to an inductance in series and links with said support. When the electromagnetism produced by the electron line of the electron componet interfers the signal, the interference signal conducts rapidly to the support through ground line and eliminates avoiding the electromagnetism interference.
