A partition of an electrical connector has a body and two extensions. The body has two outer sides opposite to each other. The extensions respectively connected to the outer sides of the body. Each of the extensions has a first bent leg, a second bent leg and an axis Each of the extensions is bent along the axis to stack the second bent leg on the first bent leg. Therefore, the thickness of the partition is increased to enhance the structure of the tongue, so that the stability of the electrical connector is enhanced.
