Abstract

The present disclosure provides an electrical connector including an insulating housing, a number of terminals and a lossy member. The terminals include a number of ground terminals and a number of signal terminals. The ground terminals and the signal terminals are set adjacently to each other but do not contact each other. The ground terminals do not directly contact the lossy member. As a result, installation consistency of the ground terminals can be achieved, thereby improving the electrical performance of the electrical connector.

First claim
