An electrical connector includes a terminal holding frame, first and second sets of conductive terminals mounted respectively on upper and lower terminal holding plates of the terminal holding frame in a superposed relationship, and a first metal shield that encloses the terminal holding frame. The metal shield has a closed rear side to enhance electromagnetic shielding of the conductive terminals. In addition, a second metal shield encloses a partition plate between the upper and lower terminal holding plates of the terminal holding frame. The second metal shield is formed with a pair of resilient grounding strips disposed forwardly of the partition plate. When the electrical connector is installed in a housing of an electronic appliance, the resilient grounding strips abut against the housing for grounding purposes.
