ABSTRACT:
An electrical connector includes an insulating housing defining two openings, a circuit board received in the insulating housing and formed with two sets of contacts, a cover covering the insulating housing and enclosing the circuit board except the sets of contacts, and a pair of grounding shells inserted into the openings respectively. Each of the grounding shells defines an inserting opening exposed through the opening of the insulating housing and a blocking opening received in the insulating housing. One of the grounding shells connects to a grounding unit of a cord telephone base, and the other grounding shell connects to a grounding unit of a portable wireless telephone to prevent the cord telephone base and the portable wireless telephone from electrostatic influence.
