Abstract
An independent loading mechanism for use with a CPU connector includes a metallic frame cooperating with a back plate module to sandwich a printed circuit board therebetween. A plurality of screw nut units are provided around the four corners of the frame. A plurality of hollow spacers are secured to the corresponding through holes of the frame so as to allow the corresponding screw nut units moveable relative to the frame along the vertical direction within a range larger than a thickness of the frame, thus avoiding improper interference between the screw nut units and the corresponding screw posts of the back plate module during sequential screwing.
