る。The wires connected to each other by the conductor pins have an external force in the wire longitudinal direction carried by the shearing force of the conductor pins, and an external force that separates the connected wires in the wire radial direction is tape winding. Since it is carried by an insulating sheath such as the above, if the shearing force of the conductor pin and the insulating sheath are given appropriate strength, the wire connection strength required for practical use can be secured. Therefore, in the connecting portion of the electric wires, there is little possibility that the electric wires are separated from each other or the conductor pin is pulled out, and the conductive connection posture is stabilized. If the shape and size of the conductor pin are designed carefully so that the tip of the conductor pin that pierces the wire does not stick out of the insulation coating and become a harmful protrusion, the insulation sheath will be destroyed from the inside. There is no such thing, and the insulating property of the connection part is well stabilized.
