ABSTRACT:
A center processing unit (CPU) socket holds a CPU and has a base and a cushion. The base has a bottom, a contact seat, multiple contacts, a cover and a latch. The contact seat is mounted in the bottom and has a recess. The contacts are mounted in the recess in multiple lines. The cover is mounted pivotally on the base and has a latch tab. The latch has a locking tab selectively engaging the latch tab. The cushion is mounted in the recess and has multiple springs and a CPU backplate. The springs are mounted in the recess. The CPU backplate is mounted on the springs and has multiple slots corresponding to the contacts. The CPU backplate cooperates with the springs during installation of a CPU to oppose a force pushing the CPU down in the CPU socket so the contacts will not be damaged.
