Abstract
Abstract A vapor-proof connector on a metal electric conduit includes an externally threaded tubular body engaging the end of the conduit and a gland nut spaced inwardly of an engaging the tubular body. The gland nut has an inwardly directed peripheral flange with a tapered inside face confronting a tapered end face of the body to delineate an annular space which surrounds the conduit and houses a channel-shaped resilient split metal ring having inwardly directed diverging flanges provided at its split ends with opposing reduced width tongues having enlarged arrow-shaped heads terminating in vertical flat end faces. A coupler of external shape similar to but thicker than that of the split ring has a rectangular longitudinal bore interrupted by a transverse wall. The tongues engage the bore and the tightening of the gland nut compresses the ring to urge the end faces of the ring and head into sealing engagement with the coupler end faces.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
128 words
A connector device for an electrical conduit comprising first and second collars having mating inner and outer threaded sections and inner peripheral confronting faces delineating an annular space, a split ring formed of a relatively hard material registering with said annular space and having confronting end faces, axially aligned tongues of reduced width directed toward each other from said ring end faces, and a coupling member of a non-metallic resilient material disposed between said ring end faces and having a longitudinal bore peripherally aligned with and engaged by said tongues, said coupling member having end faces said split ring being entrapped between said collar confronting faces and being compressible thereby to bring said ring end faces into compressible sealing engagement with said end faces of said coupling member.
Claim 2
Dependent Claim
128 words
A connector device for an electrical conduit comprising first and second collars having mating inner and outer threaded sections and inner peripheral confronting faces delineating an annular space, a split ring formed of a relatively hard material registering with said annular space and having confronting end faces, axially aligned tongues of reduced width directed toward each other from said ring end faces, and a coupling member of a non-metallic resilient material disposed between said ring end faces and having a longitudinal bore peripherally aligned with and engaged by said tongues, said coupling member having end faces said split ring being entrapped between said collar confronting faces and being compressible thereby to bring said ring end faces into compressible sealing engagement with said end faces of said coupling member.
Claim 3
Dependent Claim
28 words
The connector device of claim 1 wherein said coupling member is formed of a synthetic organic polymeric resin and said split ring is formed of a resilient metal.
Claim 4
Dependent Claim
15 words
The connector device of claim 2 wherein said split ring includes inwardly diverging annular flanges.
Claim 5
Dependent Claim
43 words
The connector device of claim 3 wherein said tongues are longitudinally aligned and are delineated from said split ring by upper and lower shoulderS defining said confronting end faces, which are in hermetically sealing engagement with the end faces of said coupling member.
Claim 6
Dependent Claim
36 words
The connector device of claim 4 wherein said coupling member includes a transverse wall extending across said bore between the ends thereof, the confronting ends of said tongues facing the opposite faces of said transverse wall.
Claim 7
Dependent Claim
30 words
The connector device of claim 5 wherein each of said tongues is of lesser width than said bore and terminates in an enlarged head of greater width than said bore.
Claim 8
Dependent Claim
30 words
The coupling device of claim 6 wherein each of said heads terminates in a vertical end face, the top and bottom edges of said head converging toward said end face.
Claim 9
Dependent Claim
19 words
The coupling device of claim 1 wherein said coupling member is of channel shape with inwardly diverging longitudinal flanges.
Claim 10
Dependent Claim
14 words
The device of claim 1 wherein said coupling member comprises an integrally formed unit.
Claim 11
Dependent Claim
25 words
The coupling device of claim 5 wherein the end faces of said tongues bear on opposite faces of said transverse wall of said coupling member.
Claim 12
Dependent Claim
42 words
The device of claim 1 wherein said coupling member comprises an outer section having a longitudinal channel formed thereon and an inner panel secured to the inner face of said outer section in registry with said channel to delineate said longituding bore.
