Abstract: A CPU carrier compatible with high density multiple pins is used to enhance the contact between conductive terminals and CPU connector pins. On bottom of a top cover of CPU carrier is a formation of a space that is somewhat recessed and elevated. On a bottom side of each pinhole of the top cover is a formation of vertically extended auxiliary arm with a length no more than the height of said space. On a top of a conductive terminal that is inserted an insert hole of the CPU carrier unit and corresponding to the auxiliary of the top cover, is a horizontal extension of arched flexible clip. When the CPU is inserted, the flexible clip and the pin can be contacted firmly to avoid vibration, impact, and some problems caused by flexible fatigue, to enhance electrical conductivity between the CPU pin and conductive terminal and to enhance product quality.
