A connector receptacle includes an insulating housing, a plurality of contacts, a protective plate, and a metallic shell. The insulating housing includes a base portion and a tongue portion extending from the base portion. The tongue portion defines a plurality of receiving slots through the base portion. The contacts are inserted into the receiving slots, and a power contact exists among the contacts. The protective plate includes a planner main portion and two connecting arm portions. The planar main portion is disposed on the tongue portion, and includes a planar section, a front section, a side section, and a connecting section. One lateral side of the planar section is a cutting notch exposing parts of the tongue portion which corresponds to the power contact. The cutting notch prevents the power contact and the protective plate from contacting while connecting with a plug, so as to secure the safety.
