The present invention proposes an improved structure for preventing electromagnetic interference (EMI) of a central processing unit (CPU), which structure includes a base, a shielding element, at least a first pin, and at least a second pin. The present invention is characterized in that fixing pins are formed by extending downwards two opposite sides of the shielding element. When the shielding element is closed, it can be firmly gripped at two sides of the base via the fixing pins thereof. Because the shielding element can be steadily closed, the lapping parts thereof can contact exactly with the main body of the second pin so that the second pin can be electrically grounded with the motherboard. Therefore, better electromagnetic shielding function can be achieved. Moreover, the bottom ends of the solder parts of the first pin and the second pin are bent to form flat shapes so that solder parts thereof can be soldered on the motherboard by using the surface mounting technique. The first pin and the second pin need not be plugged into the motherboard so that connection holes are no longer required on the motherboard. Therefore, the circuit layout of the motherboard will not be influenced.
