ABSTRACT:
A twist-on wire connector includes a closed end, an open end and an interior wall defining an elongated cavity. Grooves are provided in the cavity adjacent the first end. The grooves extend radially outwardly toward the wall of the cavity. Ribs extend along the walls. Each rib has a first terminal end aligned adjacent an associated one of the grooves. Each rib has a contoured surface which is convex in a direction transverse to the length of the rib. A helical coil wire insert has a contoured surface for mating engagement with the contoured ribs. The insert has a terminal wire end extending radially into one of the grooves. An annular undercut protrudes from the wall adjacent a second terminal end of each rib. The insert has an enlarged annular end engaged with the undercut, whereby the insert is retained in press-fit engagement within the cavity.
