Abstract
A twist-on connector for electrical wires has a shell of insulating material and a metal coil inserted into an aperture in the shell. The aperture extending from one end of the shell and has an outer tapered section which is threaded to engage the electrical wires. A beveled section of the aperture extends inwardly from the outer tapered section to an intermediate tapered section. The intermediate tapered section is formed by a threadless region which is proximate to the beveled section and a threaded region extending inward from the threadless region. A closed end section of the aperture adjoins the intermediate tapered section. The coil is frusto-conical with several turns at the larger end engaging the threadless region of the aperture and the smaller end engaging the closed end section of the aperture. The middle coil portion is spaced from the shell. Cooperation of the shell aperture sections and the coil enables the coil to be pressed directly into the aperture without having to rotated either component during insertion which was previously required to avoid thread damage.
