  • Publication number: 20110097912
    Abstract: An electrical protection for mounting on a wire connector housing, wherein the wire connector housing comprises a fixed hole and a plurality of wire-lock apertures exposed on a top surface of the wire connector housing, and the electrical protection comprise an insulating body and an insulating protrusion located at bottom surface of the insulating body. The insulating body is used to cover the wire-lock apertures at the top surface of the wire connector housing, and the insulating protrusion is designed and constructed to fit into the fixed hole of the wire connector housing. The wire-lock apertures of the wire connector housing are all covered and insulated to prevent electrical shock from the electrical leakage through the exposed apertures.
