A modular jack (100) adapted for receiving a pair of mating connectors includes an insulative housing (1) having a pair of cavities (10) for receiving the corresponding mating connectors, a number of terminal modules (3) received in the cavities for electrically connecting with the mating connector, and a conductive outer shield (2) enclosing the corresponding insulative housing. The modular jack further has a detachable grounding member (7) made from conductive material and electrically connected with the conductive outer shield for grounding. The grounding member has a number of contacting plates (7121,7131,7141) extending into the corresponding cavities for connecting and grounding the corresponding mating connectors.
