A card connector includes an insulating holder base having a first slideway and a second slideway formed on both sides of a plug-in space therein, a terminal set with multiple conductive terminals set in the plug-in space, and a push-push mechanism including a main sliding seat and an auxiliary sliding seat independently structured and respectively set in the first slideway and the second slideway. The main sliding seat is provided with a first resisting arm, and a cyclic guide groove and a guide rod for sliding positioning. The auxiliary sliding seat has a second resisting arm. The first resisting arm and the second resisting arm are used for resisting and moving a combined structure of a preset SIM card and a tray, so that when the main sliding seat and the auxiliary sliding seat are moving, the main sliding seat has a greater resistance than the auxiliary sliding seat.

An electrical connector for use in an electrical connector system which controls cross talk and signal radiation. The electrical connector having a plurality of modules with mating ends and mounting ends. Signal contacts have signal mating contact receiving sections proximate the mating ends and signal circuit board mounting sections proximate the mounting ends. The signal contacts are angled relative to a plane of the mounting ends of the modules, wherein the signal mating contact receiving sections are offset from the signal circuit board mounting section. Ground contacts have ground mating contact receiving sections proximate the mating ends and ground circuit board mounting sections proximate the mounting ends. The ground contacts are angled relative to the plane of the mounting ends of the modules, wherein the ground mating contact receiving sections are offset from the ground circuit board mounting sections.
