Abstract

A card edge cable connector assembly is disclosed. The card edge cable connector assembly includes an insulating housing, a first circuit board, a cable, and a cover. The insulating housing includes inserted a plurality of first terminals and a plurality of second terminals, where the first terminals and the second terminals can be electrically connected to the cable via the first circuit board. The first terminals are above the second terminals, and contacts of the first terminals, and mating portions of the first terminals and mating portions of the second terminals stretch into a plug space of the insulating housing. The plug space can be used for a second circuit board to plug in such that the first terminals and the second terminals electrically contact to the second circuit board.
