Abstract

A duplex fitting including a radius cast on transition for effectively stopping advancement of the armor layer of one or more inserted cables while at the same time enabling easy passage of the conductors to the outbound end. Two inbound bores transition to a single outlet bore within the fitting. The duplex fitting includes a one-piece connector body having a leading end with a nose portion and a trailing end with two bores therein. Tubular cable retainers secured within the inbound bores snap-in connection of electrical cables to the trailing end. A fastening arrangement on the nose portion of the duplex fitting enables snap fit connection to a knockout hole in a panel or an electrical box.

Claims (24)

1. A duplex fitting for connection of electrical cables to an electrical box comprising:

a tubular connector body including a nose portion, two inbound bores and a transition area leading to an outbound bore;

a dividing wall separating said inbound bores, said dividing wall including an outbound end;

an end stop at the outbound end of including an edge at the transition area;

an arcuate edge on said end stop;

said connector body including an inbound end and an outbound end;

a snap ring on said nose portion of said connector body; and

a cable retaining ring secured in each of said inbound bores of said connector body.

2. The duplex fitting of claim 1 wherein said fastening arrangement further comprises:

a cylindrical seat on said nose portion on said outbound end of said connector body; and

3. The duplex fitting of claim 1 wherein said fastening arrangement further comprises:

threads on said outbound end of said connector body; and

a locknut for engaging said threads.

4. The duplex fitting of claim 1 further comprising:

an inner periphery on each of said inbound bores; and

a chamfer extending around the inner periphery of said inbound bores.

5. The duplex fitting of claim 1 wherein each of said cable retaining rings comprises an outward extending tang.

6. The duplex fitting of claim 1 wherein each of said cable retaining tangs is a split ring.

7. The duplex fitting of claim 1 wherein said snap ring is a split ring.

8. The duplex fitting of claim 1 further comprising:

tubular inbound walls defining said inbound bores; and

a reinforcing rib extending longitudinally along the tubular inbound walls.

9. The duplex fitting of claim 8 wherein said reinforcing ribs are aligned with the plane dissecting the side-by-side inbound bores.
