Abstract

A first electrical connector includes a first housing and a first mating module. The first mating module includes a number of first cable modules and a first fixing block. Each first cable module includes a first terminal module, a first cable and a metal shielding sleeve. The first terminal module includes a first conductive terminal, and the first conductive terminal includes a first contact portion. The metal shielding sleeve includes a first side wall, a second side wall, a third side wall, a fourth side wall and a shielding cavity. The first contact portion at least partially protrudes into the shielding cavity, thereby improving the shielding effect. A connector assembly having the first electrical connector is also disclosed.
