One-piece electrical fitting for snap connection
A one-piece electrical fitting for connecting an electrical cable to a junction box, the electrical fitting formed from a single, flat blank of metal into a cylindrical connector body. The connector body includes a leading end having an exit bore, a trailing end, a cap, an inner bore, and one or more combination tangs including grounding tangs, locking tangs, and flanges extending radially outward from the connector body. The exit bore in the cap is offset to one side with cable retaining tangs on the fitting configured to push toward the exit bore in order to ease insertion of cables and conductors through the fitting. The one-piece electrical fitting includes a connector body with a D-shaped cross-sectional profile and one or more auxiliary grounding tangs extending outward from the connector body to improve grounding of the fitting with respect to an electrical box.
1. A one-piece electrical fitting, comprising:
a tubular connector body having a leading end, a trailing end, a central axis, and a trailing bore, said tubular connector body having a constant diameter from said leading end to said trailing end;
a grounding tang extending outwardly from the tubular connector body;
a locking tang extending from the interior of the grounding tang;
a cap including an exit bore;
one or more cable retaining tangs to direct an electrical cable from the trailing bore to the exit bore; and
one or more auxiliary grounding tangs on said tubular connector body.
2. The one-piece electrical fitting of claim 1 , comprising a single longitudinal seam on said connector body.
3. The one-piece electrical fitting of claim 1 , comprising:
said exit bore includes a central axis; and
said central axis of said exit bore is offset from said central axis of said connector body.
4. The one-piece electrical fitting of claim 2 , comprising:
said longitudinal seam includes two joined edges;
a first of said edges including edge tabs;
a second of said edges including slots for accepting said edge tabs; and
the joined edges are locked flush together in a gap-free locking arrangement of edge tabs extending into corresponding slots.
5. The one-piece electrical fitting of claim 1 , comprising:
a rolled edge on said trailing end of said connector body; and
said edge is rolled outwardly of said tubular connector body.
6. The one-piece electrical fitting of claim 5 , comprising a gap on the trailing end of the connector body, said gap including an unrolled portion of said trailing end of said connector body.
7. The one-piece electrical fitting of claim 1 , wherein the cap includes a narrow aspect and a wide aspect.
8. The one-piece electrical fitting of claim 1 comprising a flange on said grounding tang, said flange to contact and establish electrical continuity with the wall of an electrical box.
9. The one-piece electrical fitting of claim 1 comprising said one or more auxiliary grounding tangs on said tubular connector body to contact and establish electrical continuity with the electrical box wall surrounding the knockout aperture.
