ABSTRACT:
This is a screw-on electrical connector of the type in which an insulating cap has a generally open central bore and a wire coil is positioned in the bore to engage the stripped ends of the wires. The interior of the bore is provided with a formation to engage the rear end of the coil for positioning and interlocking the two to provide the torque necessary to turn the connector down on the stripped ends of the wires. The forward portion of the bore is also provided with a dam structure or barrier to prevent the coil from coming out of the bore. The subject matter includes a method of making such a connector.
