Electrical connector assembly with better anti-interference and grounding effects

Abstract

An electrical connector assembly includes: an insulative housing; a terminal module assembly received in the insulative housing and including an upper part and a lower part stacked with each other in a vertical direction, each of the upper part and the lower part having a high-speed terminal module and a sideband terminal module, each of the high-speed terminal modules including plural 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.
