Conduit connector assembly with end stop grommet for attachment of conduit to junction box
First Claim
1. A conduit connector assembly for attachment of a conduit carrying electrical wires to an electrical junction box, said assembly comprising:
- (a) a fitting body having open first and second opposite ends and an interior bore extending between said first and second opposite ends for receiving therein from said first opposite end an end portion of a conduit carrying electrical wiring which emanates from the end portion of the conduit, said fitting body at said second opposite end being insertable through an opening in an electrical junction box;
(b) an end stop grommet interfitted with said fitting body, said end stop grommet including(i) a grommet body having open first and second end portions and defining an interior cavity extending between said first and second end portions, said first end portion of said grommet body being inserted within said interior bore of said fitting body from said second opposite end thereof to a predetermined position within said interior bore of said fitting body, said first end portion of said grommet body being of a first diameter size adapted to receive the end portion of the conduit therein,(ii) outer means on said second end portion of said grommet body defining a first stop element for preventing said grommet body from being inserted into said interior bore of said fitting body beyond said predetermined position, and(iii) inner means on said second end portion of said grommet body defining a second stop element for blocking extension of the end portion of the conduit through said second end portion of said grommet body, said inner means also defining an aperture of a second diameter size less than said first diameter size for allowing passage of the electrical wiring emanating from the end portion of the conduit through said second end portion of said grommet body;
(c) means for securing said end stop grommet to said fitting body, said means for securing including(i) wall portions on opposite sides of said fitting body defining a pair of openings and a pair of edges extending along said openings and facing in a first direction toward said first opposite end of said fitting body, and(ii) a pair of locking tabs disposed on opposite sides of said first end portion of said grommet body and protecting outwardly therefrom, each of said locking tabs having an edge facing in a second direction opposite from said first direction and toward said second opposite end of said fitting body for making locking engagement with one of said edges on said fitting body upon insertion of said first end portion of said grommet body within said interior bore of said fitting body to said predetermined position within Said interior bore of said fitting body;
(d) means on said fitting body for gripping the end portion of the conduit so as to hold the conduit end portion within said interior bore of said fitting body; and
(e) means on said fitting body for connecting said fitting body to the electrical junction box.

Abstract
A conduit connector assembly for attachment of a conduit carrying electrical wires to an electrical junction box includes a fitting body, an end stop grommet, and a spring clip. The fitting body has open first and second opposite ends and an interior bore for receiving therein an end portion of a conduit. The end stop grommet includes a grommet body having an interior cavity with open first and second end portions, the grommet body being inserted within the interior bore of the fitting body. The conduit is received and held within the interior bore of the fitting body and within the interior cavity of the grommet body. The fitting body is inserted through an opening in the junction box and is connected thereto. The grommet body is secured within the interior bore of the fitting body and has an outer flange making contact with the fitting body for preventing the grommet body from being inserted into the fitting body beyond a predetermined position therein. The grommet body also has an end wall having a round passage therethrough to prevent the conduit from entering farther into the junction box but permits wiring from the conduit to pass into the junction box. The spring clip retains the conduit within the fitting body and cooperates with the fitting body for connection of the assembly to the junction box.
