Claim:
An electrical connector for terminating an electrical conduit having a protective rounded rim to avoid wire insulation damage, comprising: a locking hub nut, wherein said locking hub nut is toroid-shaped and has a rounded end and a flat end, said locking hub nut having a central axial bore extending therethrough, said locking hub nut having an external surface having a plurality of recessed portions that define a plurality of ribs for cooperative engagement during conduit installation, wherein said ribs do not project beyond the external diameter of the locking hub, wherein the central axial bore is screw-threaded along an inner surface, wherein the rounded end has a rounded rim, said rounded rim having a substantially smooth surface and extending inwardly into the central axial bore, and wherein the rounded rim joins the exterior surface to create a continuous smooth surface, wherein upon threading wiring through the central axial bore the rounded rim guides the wiring travelling therethrough in such a manner that there is minimal interaction with any sharp edges while being pulled through a length of conduit and interacting with the locking hub nut during such a pull operation, and wherein the locking hub nut has a height from flat end to rounded end of from about 11 mm to about 16 mm and provides for engagement with a junction box without using a lock nut.
