Ic socket with floatable pressing device for receiving testing ic packages of different sizes

An electrical connector assembly comprising:

• an IC socket having an insulative housing adapted to accommodate an IC package;
• a pressing device pivotally attached to the insulative housing;
• and
• at least one pair of first shafts assembled on two opposite ends of the insulative housing and being moveable in a vertical direction following the pressing device in the vertical direction.

An electrical connector assembly comprising:

• an insulative housing defining an IC receiving cavity;
• first shaft and second shaft being located around two opposite ends of the housing;
• and
• a foldable pressing device including a lower part pivotally connected to the first shaft and an upper part hooked to the second shaft;
• wherein
• both said first shaft and said second shaft are floatable at least in a vertical direction while constantly urged to move downwardly for compliantly holding different IC packages in the IC receiving cavity.
