Abstract

A ninety degree snap fit electrical fitting for enabling rapid snap-fit insertion of an electrical cable to an electrical box. The ninety degree snap fit electrical fitting includes a connector body having a leading end, a trailing end, an internal bore, a box connection arrangement on the leading end, and a cable connection arrangement on the trailing end. A seat on the leading end of the connector body includes a snap ring with an outward extending locking tang. An internal snap ring is secured within the internal bore of the connector body at the trailing end. A cable retaining tang on the internal snap ring is adapted to engage and secure an electrical cable to the trailing end of the connector body.

Claims4

Dependent claims

A snap fit electrical fitting, comprises:

a one-piece connector body including a sidewall, a leading end having a circular outlet bore with an outlet axis, and a trailing end having a circular inlet bore with an inlet axis, said inlet axis and said outlet axis are at an angle to one another;
a leading flange extending around the periphery of said leading end of said connector body and a trailing flange between said leading end and said trailing end of said connector body;
said sidewall at said trailing end including a straight sidewall portion including a first inlet chamber and a second inlet chamber, said second inlet chamber including an inner periphery and an interior end;
a cylindrical sidewall portion extending from said straight wall portion to said leading end;
an internal shoulder is between said straight sidewall portion and said cylindrical sidewall portion;
an outer flange is between said trailing flange and said internal shoulder, said outer flange extending from said cylindrical sidewall portion of said connector body;
an outside bend and an inside bend of said connector body;
said angle between said inlet bore and said outlet bore is between 60 and 120 degrees;
a reduced-diameter seat has a constant diameter, and is on said leading end of said connector body, said seat extending from said leading flange to said trailing flange;
a snap ring is disposed on said seat;
an internal snap ring is within said first inlet chamber of said connector body;
a pusher tang is on said inside bend of said snap fit electrical fitting;
said pusher tang directing a cable inserted within said inlet bore toward said outside bend of said connector body;
and
axially aligned openings extending through the sidewall on the second inlet chamber of the connector body, wherein the axially aligned openings are substantially orthogonal to a part of the straight side wall portion connecting to the outside bend.
