Raintight compression connector and raintight compression coupler for securing electrical metallic tubing or rigid metallic conduit

摘要

A raintight compression connector has a connector body with first and second portions and a bore extending therethrough. The first portion is dimensioned for receipt of an EMT or RMC conduit. A gland nut threads onto the first portion and a split compression ring contacts the gland nut so as to secure the connector body to the conduit. An upper sealing ring makes sealing contact with the conduit; and a wedge-shaped sealing ring is positioned in the bore of first portion against a shoulder formed in the first portion. The sealing ring contacts a terminating face of the conduit so as to pliably deform around the face so as to form a watertight seal. The second portion is securable to an enclosure. A coupler with two portions similar to the first portion of the connector has corresponding components to form a watertight seal with two conduits.

主权项

1. A raintight compression connector comprising:
a connector body having a first portion and a second portion and a bore extending through the first portion and the second portion, the first portion dimensioned for receipt of a conduit in said bore, the first portion having a first end and a second end; a gland nut having internal threads dimensioned for threaded engagement with first external threads formed in the first portion at the first end; a split compression ring dimensioned for contact with the gland nut so as to secure the gland nut and the first portion of the connector body to the conduit when the conduit is inserted into the first portion; an upper sealing ring dimensioned for contact with the first portion of the connector body so as to make sealing contact with the conduit when the conduit is inserted into the first portion; and a wedge-shaped sealing ring positioned in the bore of the first portion against a shoulder formed in the first portion at the second end thereof, said wedge-shaped sealing ring having a tapered surface that faces toward itself and extending from the shoulder where the wedge-shaped sealing ring has a maximum cross-sectional width, toward the first end of the first portion, where the wedge-shaped sealing ring has a minimum cross-sectional width, the tapered surface of the wedge-shaped sealing ring dimensioned to contact a terminating face of the conduit so as to pliably deform around the conduit terminating face so as to form a watertight seal between said conduit terminating face and the shoulder; wherein the connector body has an outer flange and wherein the second portion of the connector body is dimensioned for receipt of a knockout gasket, the second portion having second external threads dimensioned for receipt of a locknut for securing the knockout gasket positioned around a knockout hole in an electrical enclosure between said outer flange and the electrical enclosure, thereby forming a raintight seal therewith.
