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 for connection to a conduit. An upper sealing ring is dimensioned to contact the connector body to make sealing contact with a conduit. The upper sealing ring has first, second and third regions. The first region has a first sloping surface to contact a recess shoulder in the connector body and the third region has a third sloping surface to contact an inner surface of the connector body. Specific slopes for these sloping surfaces are disclosed. The upper sealing ring can also be used in a raintight compression coupler.

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 gland 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, said upper sealing ring having first, second and third regions, the second region formed between the first and third regions, the first region having a first sloping surface dimensioned to contact a recess shoulder in the bore of the first portion of the connector body and the third region having a third sloping surface dimensioned to contact an inner surface of the first portion of the connector body; and a stop seal positioned in the bore of first portion against a shoulder formed in the first portion at the second end thereof, the stop seal 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.
