Abstract

A second electrical connector includes a second housing and a second mating module mounted to the second housing. The second mating module includes a number of second cable modules and a second fixing block fixed on the second cable modules. Each second cable module includes a second terminal module, a second cable, a second shielding clamping plate clamping the second cable, and a metal shield surrounding member at least partially sleeved on the second terminal module. The second shielding clamping plate is in contact with the metal shield surrounding member, thereby increasing the ground shielding area and improving the shielding effect. A connector assembly having the second electrical connector is also disclosed.
