A socket connector packaging includes a main body and a cover. The main body includes a first sidewall and a pivot positioned on the first sidewall. The cover includes a second sidewall, a coupling portion and a stop portion. The coupling portion and the stop portion are positioned on the second sidewall and opposite to each other. The pivot is placed over the coupling portion, thereby making the cover to be rotatable relative to the main body through the pivot. The stop portion is configured for preventing the cover from further rotating when the pivot contacts with the stop portion.
