Abstract
A cable connector includes an insert having a tubular body portion with a conical end portion longitudinally spaced from an annular flanged end portion by diametrically opposed radial grooves. The insert is positioned in an aperture extending through a wall of an electrical junction box. The tubular body portion is contractable to permit the wall surrounding the aperture to be positioned in surrounding relation with the grooves to retain the tubular body portion in the aperture. A passageway extends through the tubular body portion and includes a rectangular inlet and a rectangular outlet. Vertical sidewalls of the passageway diverge outwardly from the inlet to the outlet so that the cross sectional area of the outlet is greater than the cross sectional area of the inlet. A pair of wedge shaped members are positioned in the passageway to secure a cable, such as an insulated conductor, extending through the passageway from being pulled out of the junction box. As the cable is moved in an axial direction through the insert from the inlet to the outlet of the passageway, the cable passes between the wedge-shaped members and urges the wedge-shaped members outwardly into abutting relati…
