Abstract

A stacked electrical connector comprises an insulative housing, a number of contacts received in the insulative housing, a metal shell enclosed the insulative housing and a metal plate received in the insulative housing. The insulative housing has a main body and a spacer mounted to the main body. The plate is received in the spacer and extending out of the spacer partly. The plate abuts against the metal shell forwardly. As a result, cross-talk between the contacts can be reduced and it would improve signal transmission quality of the stacked electrical connector.
