Electrical fitting for snap connection of electrical cable to a junction box
A one-piece electrical fitting for connecting an electrical cable to a junction box, the electrical fitting including a tubular connector body including a leading end, a trailing end, a cap, an inner bore, and one or more grounding tangs and locking tangs. The grounding tangs include flanges and the locking tangs include free ends. A seat extends between the flanges of the grounding tangs and the free end of the locking tangs. One or more cable retaining tangs extend inward from the connector body into the inner bore. The electrical fitting is stamped and formed from a flat blank of metal. A tab and notch arrangement on the blank facilitates forming the blank into the tubular connector body. The fitting provides electrical continuity between the electrical cable, the fitting, and the junction box and stain relief to resist inadvertent removal of the electrical cable from the fitting.
1. An electrical fitting, comprising:
a one-piece fitting including a tubular connector body having a leading end, a trailing end, a wall, and a bore;
a grounding tang extending outward from said connector body;
a locking tang extending outward from said grounding tang;
a cable retaining tang extending inward of said connector body into said bore;
a cap on said leading end of said connector body;
an outer periphery and an opening in said cap;
a lip including a rolled over portion of said cap at said opening,
a hinge extending from said connector body to said cap;
a notch on said cap on an opposing side of said cap from said hinge; and
a tab extending from said connector body and folded over the cap at the notch.
2. The electrical fitting of claim 1 , further comprising:
a flange on said grounding tang; and
said flange of said grounding tang is perpendicular to said wall of said connector body.
3. An electrical fitting, comprising:
a tubular one-piece connector body including a wall, a leading end, a trailing end, and a bore;
a grounding tang extending outward from said connector body;
a locking tang extending outward from said grounding tang;
a cable retaining tang extending inward of said connector body into said bore;
a first edge and a second edge on said connector body, said first edge and said second edge including a tab and slot arrangement for locking said edges of said connector body into the tubular shape, said tab and slot arrangement having a tab on said first edge and a slot on said second edge, said tab including an inner surface and an outer surface;
said tab and slot arrangement including a side extension on said tab and a side channel on said slot;
said first edge and said second edge in a flush fit forming a longitudinal seam along said connector body; and
said tab of said tab and slot arrangement matching the radius of curvature of said connector body.
4. The electrical fitting of claim 3 , further comprising:
a flange on said grounding tang; and
said flange of said grounding tang is perpendicular to said wall of said connector body.
5. The electrical fitting of claim 4 , further comprising:
a cap on said leading end of said connector body; and
a forwardly-outturned lip on said cap.
6. The electrical fitting of claim 3 , further comprising said grounding tang is wider than said locking tang.
7. The electrical fitting of claim 4 , further comprising:
a free end on said locking tang;
said flange and said grounding tang are in longitudinal alignment along said connector body; and
a seat between said flange of said grounding tang and said free end of said locking tang.
8. The electrical fitting of claim 7 , wherein said free end of said locking tang is flat.
9. An electrical fitting, comprising:
a tubular non compressible one-piece connector body including a diameter, a leading end, a trailing end, a linear longitudinal seam including two longitudinal edges, and a bore;
a grounding tang extending outward from said connector body;
a locking tang extending outward from said grounding tang, said locking tang including an arcuate free end;
a cable retaining tang extending inward of said connector body into said bore;
a cap at said leading end;
a forwardly-outturned lip on said cap;
said arcuate free end of said locking tang is of greater diameter than the diameter of said connector body;
a first edge and a second edge on said connector body;
a tab extending from said first edge and a slot in said second edge of said connector body; and
said tab of said connector body matching the radius of curvature of the connector body with the inner surface of said tab flush with the inner surface of said connector body and the outer surface of said tab flush with the outer surface of said connector body.
10. The electrical fitting of claim 9 , further comprising:
an axial center on said connector body; and
said locking tang is offset radially from said cable retaining tang with respect to the axial center of said connector body.
