A central processing unit (CPU) socket includes: a base (1) receiving contacts (2) therein; a cover (3) movably mounted on the base; and an actuation device (4) including a camshaft (41) rotatably engaged between the base and the cover, and a handle (42). The base defines a transverse first channel (12) at one end thereof, the first channel receiving the camshaft therein. A pin (43) extends coaxially from a free end of the camshaft. A recess (131) is defined in a sidewall (13) formed on the base at one end of the first channel. The pin is rotatably received in the recess. Accordingly, when the actuation device is rotated to drive the cover to slide relative to the base, a rotational axis of the camshaft is prevented from being displaced upwardly. Thus the camshaft does not disturb the cover, and correct engagement between the cover and the base is maintained.
