ABSTRACT:
Prior to coiling, the wire to be used as the spring insert of twist-on connectors is mechanically worked to form at least two relatively sharp edges. When coiling is accomplished such edges are positioned to extend inwardly into the core of such coils to mechanically engage and retain conductors placed within said core.
Similar sharp edges can be formed on spring inserts having a wide range of initial cross-section profiles.
