Abstract

A first terminal module includes a first insulating block, a first terminal group and a first shielding sleeve. The first terminal group includes a first conductive terminal and a second conductive terminal. The first conductive terminal includes a first contact portion protruding into the first receiving cavity. The second conductive terminal includes a second contact portion protruding into the first receiving cavity. The first contact portion and the second contact portion are offset from each other. The first shielding sleeve includes a first end portion and a number of first slits extending through the first end portion. The slits are distributed along a circumferential direction of the first shielding sleeve. A first electrical connector having the first terminal module and a connector assembly having the first electrical connector are also disclosed.
