  • Patent number: 6489555
    Abstract: An elastic system for preventing electromagnetic interference to a computer central processing is disclosed. Two lateral sides of the contact surface and the welding surface are extended with a vertical upper stopper and a vertical lower stopper; upper portions of the upper stopper and the lower stopper are alternatively arranged. Therefore, each elastic conductive piece has a closed structure. No outer object will be hooked or fall thereinto. A hole is formed on the welding surface. Since the welding surface is combined to the computer mainframe board through a tin glue. Therefore, the computer mainframe board has a preferred sticky force.

  • Patent number: 6359215
    Abstract: An elastomer for preventing electromagnetic interruption to a computer central processing unit includes at least one elastic conductive piece. An enhancing portion is bent inwards between the second arc portion and the welding surface. The lower edge of the enhancing portion is formed with an inclined surface having a proper orientation (preferably 45 degrees). Thereby, as the elastic conductive piece is pressed downwards, it can be avoided that the combining portion of the second arc portion, welding surface and tin glue is broken.

  • Patent number: 6346672
    Abstract: 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.
