    摘要： Located within a GFCI is a movable contact bearing arm which cooperates with at least one fixed contact. When the movable arm is moved up to allow the at least one contact on the arm to close with at least one fixed contact, the GFCI is in a conducting state and current flows from a source of electricity through the closed contacts to a load and to the contacts of a receptacle. When the movable arm is moved down to open the contacts, the GFCI is in a non-conducting state and current cannot flow from the source of electricity to either the load or the receptacle contacts. In this invention, the up and down movement of the movable contact bearing arm is harnessed to move a blocking member located within the housing of the GFCI to a first position to block at least one opening of the receptacle as the movable arm is moved down or to a second position to allow the prongs of a plug to enter the openings of the receptacle as the movable arm is moved up. The downward movement of the movable contact bearing arm occurs when the GFCI goes into a non-conducting state. Resetting the GFCI by pressing in and then releasing a reset button causes the movable contact bearing arm to move up to make contact with the at least one fixed contact. As the movable arm moves up, the blocking member moves to the first or non-blocking position to allow the prongs of a plug to freely enter the openings in the face of the receptacle. GFCI's normally have two separate sets of internally located contacts known as bridge contacts where one set is used to connect a load to the source of electricity and the second set is used to connect a user accessible load to the source of electricity. The bridge contacts provide isolation between the conductors to the load and the conductors to the contacts of the GFCI receptacle when the GFCI is in a non-conducting state. In the GFCI here disclosed, the blocking member prevents the prongs of a plug from entering the receptacle when the GFCI is in a non-conducting state and, therefore, the need for the bridge contacts is diminished.

    摘要： Located within a GFCI device having a receptacle is a movable contact bearing arm which is held in either a closed or open position with a fixed contact by a latching member that is connected to the spring loaded reset button. The reset button assumes a first or a second position which is determined by the conductive state of the GFCI. When the GFC is in a conducting state, the reset button is substantially fully depressed within the housing of the GFCI. When the GFCI is in a non-conductive state, the reset button projects outward beyond the top surface of the housing of the GCFI. Thus, the movable contact bearing arm, acting through a latching member, determines the position of the reset button. A blocking member located within the body of the GFCI is positioned by the reset button to allow free access of the prongs of a plug into the openings of the receptacle when the reset button is depressed or to block at least one opening of the receptacle to prevent a plug from entering the openings of the receptacle when the reset button projects out beyond the surface of the housing. Thus, when the GFCI is in a conducting state, the reset button is recessed within the GFCI housing and positions the blocking member to the first position to allow the prongs of a plug to be inserted into the receptacle openings. When the GFCI is in a non-conducting state, the reset button protrudes outward from the housing of the GFCI to position the blocking member to the second position to block at least one opening of the receptacle to prevent the prongs of a plug from entering the receptacle. GFCI's normally have two separate sets of internally located contacts known as bridge contacts where one set is used to connect a load to the source of electricity and the second set is used to connect a user accessible load to the source of electricity. The bridge contacts provide isolation between the conductors to the load and the conductors to the contacts of the GFCI receptacle when the GFCI is in a fault state. In the GFCI here disclosed, the blocking member prevents the prongs of a plug from entering the receptacle when the GFCI is in a fault state and, therefore, can eliminate the need for the bridge contacts.

When the movable arm is moved up to allow the at least one contact on the arm to close with at least one fixed contact, the GFCI is in a conducting state and current flows from a source of electricity through the closed contacts to a load and to the contacts of a receptacle. When the movable arm is moved down to open the contacts, the GFCI is in a non-conducting state and current cannot flow from the source of electricity to either the load or the receptacle contacts. In this invention, the up and down movement of the movable contact bearing arm is harnessed to move a blocking member located within the housing of the GFCI to a first position to block at least one opening of the receptacle as the movable arm is moved down or to a second position to allow the prongs of a plug to enter the openings of the receptacle as the movable arm is moved up. The downward movement of the movable contact bearing arm occurs when the GFCI goes into a non-conducting state. Resetting the GFCI by pressing in and then releasing a reset button causes the movable contact bearing arm to move up to make contact with the at least one fixed contact. As the movable arm moves up, the blocking member moves to the first or non-blocking position to allow the prongs of a plug to freely enter the openings in the face of the receptacle. GFCI's normally have two separate sets of internally located contacts known as bridge contacts where one set is used to connect a load to the source of electricity and the second set is used to connect a user accessible load to the source of electricity. The bridge contacts provide isolation between the conductors to the load and the conductors to the contacts of the GFCI receptacle when the GFCI is in a non-conducting state.
