ABSTRACT:
A snap-in connector for coupling a flexible metallic raceway to an electrical enclosure formed from a shell member, to engage the material about the knock-out in an electrical enclosure, and a core member, to engage, hold and ground a flexible metallic raceway. The core member has a cylindrical central portion about which is positioned an inwardly facing rib in the form of a portion of a helix to engage the voids between the covolutions of the raceway to hold the raceway and provide electrical continuity therewith. The shell member and core member are coupled together and provide a first lip to limit connector insertion into the knock-out and in cooperation with latch means to hold the connector to the material about the knock-out while the latch means prevents withdrawal of the connector from the knock-out.
