Abstract: An electrical connector includes a housing having at least one wire insertion channel for electrical wires to be inserted therein. An upper terminal in the channel has a sharp edge for piercing into the insulation of each wire and electrically contacting the conductive element of the wire. At least one lower terminal in the channel has a blunt edged element for supporting the insulated wire as the upper terminal pierces the insulation of the insulated wire. An actuator is operable for inserting into the connector and actuating a hinged plane causing the upper terminal to piercingly engage the insulated wire and make electrical contact with the conductive element of the wire.
