Abstract: An electrical connector is provided which has an insulating body with at least two open areas which may contain electrical conductors, such as insulated wires inserted into the open areas. The at least two open areas are positioned within the insulating body to support the electrical conductors in proximity. A connector bore is provided towards at least one area where the electrical conductors are in proximity. An electrically conductive element having conductive threads which are capable of cutting into and through insulation on wires is directed into the connector bore. The electrically conductive element with threads (or other screw-like, bolt-like or parallel edges extending from the sides of the electrically conductive element) is rotated within the connector bore so that the thread elements cut through the insulation (eventually or simultaneously of both wires) within at least one area where the conductors are in proximity.
