Electrical connector assembly having clip-fastening mechanism

A clip-fastening mechanism adapted to press a CPU toward a socket connector mounted on a substrate, comprising:

• a substrate having an upper and lower surface;
• a reinforcing member assembled to the lower surface of the substrate;
• and
• a load plate pivotally mounted onto the upper surface of the substrate corresponding to the reinforcing member, and including an interlocking device having an interlocking cam rotationally mounted onto a free end thereof, the interlocking cam including a channel located at a first position in which the interlocking cam is engaged with a portion of the reinforcing member, and a second position in which the interlocking cam is disengaged with the portion of the reinforcing member.

A socket assembly comprising:

• a printed circuit board defining opposite upper surface and undersurface thereof with a through hole extending through both said upper surface and said undersurface;
• a housing mounted upon the upper surface of the printed circuit board with a plurality of contacts thereof;
• a load plate located above the housing;
• a back plate mounted to the undersurface of the and defining a hole, in alignment with the through hole;
• and
• an interlocking cam extending through the load plate, the through hole and the hole;
• wherein
• a protrusion is formed in the hole and the interlocking cam defines a recess to allow said protrusion to pass therethrough when said interlocking cam is located in a first radial position, and to have the protrusion downwardly abut against the interlocking cam for locking the interlocking cam in position so as to have the load plate and the back plate are both in a tensioned manner via said interlocking cam when the interlocking cam is rotated to a second radial position.
