Electrical connector assembly with better anti-interference and grounding effects

An electrical connector assembly comprising:

• an insulative housing forming a front mating slot and a rear receiving space;
• a terminal module assembly received in the rear receiving space of the insulative housing and including an upper part and a lower part stacked with each other in a vertical direction and exposed to the front mating slot for engaging a mating connector, each of the upper part and the lower part comprising a high-speed terminal module and a sideband terminal module, each of the high-speed terminal modules including a plurality of ground terminals and differential pair terminals arranged alternately with the ground terminals in a transverse direction perpendicular to the vertical direction;
• a cable connected to the high-speed terminal module;
• and
• a ground bar located at a rear of the ground terminal and a metal shield member discrete from the ground terminal, the ground bar including a first bulged section, the metal shield member including a second bulged section, the first bulged section and the second bulged section cooperating with each other to surround the cable in a circumferential direction.
