Electrical insider fitting for internal connection to an electrical box
An electrical fitting adapted for insertion from the interior of an electrical box in order to provide a secure means for attaching an electrical cable to the box. The electrical insider fitting includes a connector body having a leading end, a trailing end, and a base flange on the trailing end. A leading face is included on the base flange and a seat on the connector body adjacent the leading face of the base flange. A snap ring resides in the seat and includes one or more outward extending locking tangs. The leading end of the connector body includes an internal bore with an internal snap ring secured therein. The internal snap ring includes one or more cable retaining tangs for engaging and securing an electrical cable to the leading end of the connector body.
1. An electrical fitting for connecting an electrical cable to an electrical box having a wall, comprising:
a connector body having a leading end including a main body portion with a leading bore for insertion through an access hole in the electrical box, and a trailing end with a trailing bore;
a base flange on said trailing end of said connector body, said base flange including a leading face;
a reduced-diameter seat on said trailing end of said connector body, said seat extending from said leading face of said base flange to said main body portion;
an external snap ring disposed on said seat of said connector body, said external snap ring including a locking tang having a free end;
an internal snap ring disposed within said leading bore of said connector body, said internal snap ring including a cable retaining tang; and
said free end of said locking tang of said external snap ring and said free end of said cable retaining tang of said internal snap ring are oriented toward the trailing end of said connector body.
2. The electrical fitting of claim 1 , including a retaining arrangement for retaining said internal snap ring within said leading bore of said connector body.
3. The electrical fitting of claim 2 , wherein said retaining arrangement includes
an opening in said connector body; and
a locking tang extending outward from said internal snap ring and through said opening.
4. The electrical fitting of claim 1 , including
an inner wall on said connector body; and
a stop on said inner wall of said connector body at the juncture of said leading bore and said trailing bore.
5. The electrical fitting of claim 1 wherein said base flange is of a larger diameter than the diameter of said main body portion of said connector body.
6. The electrical fitting of claim 1 further comprising a trailing face and a leading face on said base flange.
7. The electrical fitting of claim 1 wherein said leading face of said base flange and said free end of said locking tang of said external snap ring lock engage opposing sides of said electrical box wall.
8. The electrical fitting of claim 1 wherein engagement of said leading face of said base flange and said free end of said locking tang of said external snap ring lock said trailing end of said connector body to said electrical box.
9. The electrical fitting of claim 1 wherein said free end of said locking tang of said external snap ring and said free end of said cable retaining tang of said internal snap ring are oriented toward the trailing end of the connector body.
10. The electrical fitting of claim 1 wherein said free end of said locking tang of said external snap ring and said cable retaining tang of said locking tang of said internal snap ring are oriented toward the same end of the connector body.
11. The electrical fitting of claim 1 wherein said free end of said locking tang of said external snap ring and said free end of said locking tang of said internal snap ring are oriented toward opposing ends of the connector body.
