Abstract
Abstract A coupling including a tubular main body comprising means for fixing in a wall, and traversed by an axial channel terminating at one end in a conical flared portion. An annular nut screws onto said end of the body surrounding said flared portion. The bottom of the nut is pierced by an axial bore of diameter similar to that of said axial channel. The nut receives internally a sealing ring deformable by tightening, supported on said bottom of the nut to apply on said conical flared portion and to deform by tightening, an annular clip for anchoring said cable extending. The coupling is useful for the fluid-tight fastening of cables through a wall.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
219 words
An anchoring and sealing coupling for a cable comprising a tubular main body, means on said body for fixing said body to a wall, an axial channel extending through said body terminated at one end by a conical flared portion, an annular nut threadedly engaging on to said one end of the body encircling said conical flared portion, the outer end of said nut having an axial bore therethrough of diameter similar to the diameter of said axial channel, a deformable sealing ring within the interior of said nut and supported thereby adjacent said outer end, said sealing ring comprising a cylindrical washer of thermoplastic or elastomeric material, an annular clip between said sealing ring and said conical flared portion for anchoring a cable extending through said tubular body and nut, said annular clip comprising a cylindrical annular base having an externally conically shaped radially slotted portion extending therefrom of plastically deformable material, and an external annular groove at the juncture of said base and slotted portion, the radial slots extending into said groove, whereby tightening of said nut deforms said sealing ring causing the sealing ring to move said conically shaped slotted portion of said clip against said conical flared portion of said main body to force said radially slotted portion radially inwardly into engagement with the cable.
Claim 2
Dependent Claim
219 words
An anchoring and sealing coupling for a cable comprising a tubular main body, means on said body for fixing said body to a wall, an axial channel extending through said body terminated at one end by a conical flared portion, an annular nut threadedly engaging on to said one end of the body encircling said conical flared portion, the outer end of said nut having an axial bore therethrough of diameter similar to the diameter of said axial channel, a deformable sealing ring within the interior of said nut and supported thereby adjacent said outer end, said sealing ring comprising a cylindrical washer of thermoplastic or elastomeric material, an annular clip between said sealing ring and said conical flared portion for anchoring a cable extending through said tubular body and nut, said annular clip comprising a cylindrical annular base having an externally conically shaped radially slotted portion extending therefrom of plastically deformable material, and an external annular groove at the juncture of said base and slotted portion, the radial slots extending into said groove, whereby tightening of said nut deforms said sealing ring causing the sealing ring to move said conically shaped slotted portion of said clip against said conical flared portion of said main body to force said radially slotted portion radially inwardly into engagement with the cable.
Claim 3
Dependent Claim
163 words
An anchoring and sealing coupling for a cable, comprising a tubular mainbody, attachment means on said body for fixing said body to a wall, an axial channel extending through said body terminated at one end by a conical flared portion, an annular nut threadedly engaging said end of the body encircling said flared portion, an axial bore through the outer end of said nut of diameter similar to the diameter of said axial channel, a resilient cylindrical sealing ring within said nut and supported thereby adjacent said outer end, a deformable annular clip between said sealing ring and said conical flared portion of said tubular main body in cooperative relationship for anchoring a cable extending through said tubular body and nut, whereby tightening said nut axially compresses said resilient sealing ring causing said sealing ring to expand into tight sealing engagement with the cable and to force said clip against said conical flared portion deforming said clip into anchoring engagement with the cable.
Claim 4
Dependent Claim
163 words
An anchoring and sealing coupling for a cable, comprising a tubular mainbody, attachment means on said body for fixing said body to a wall, an axial channel extending through said body terminated at one end by a conical flared portion, an annular nut threadedly engaging said end of the body encircling said flared portion, an axial bore through the outer end of said nut of diameter similar to the diameter of said axial channel, a resilient cylindrical sealing ring within said nut and supported thereby adjacent said outer end, a deformable annular clip between said sealing ring and said conical flared portion of said tubular main body in cooperative relationship for anchoring a cable extending through said tubular body and nut, whereby tightening said nut axially compresses said resilient sealing ring causing said sealing ring to expand into tight sealing engagement with the cable and to force said clip against said conical flared portion deforming said clip into anchoring engagement with the cable.
Claim 5
Dependent Claim
28 words
A coupling according to claim 2, wherein the inner side of said outer end of the nut has a semi-toric shape at the periphery of the axial bore.
Claim 6
Dependent Claim
50 words
A coupling according to claim 2, wherein said sealing ring comprises a cylindrical washer of thermoplastic or elastomeric material, and said annular clip comprises a cylindrical annular base and an externally conically shaped radially slotted portion extending therefrom toward said conically flared portion forming a clip of plastically deformable material.
Claim 7
Dependent Claim
63 words
A coupling according to claim 4, wherein said sealing ring has an outer diameter slightly greater than that of said annular clip, whereby said sealing ring is supported in the compressed state on a marginal portion at the end of the main body where the conical flared portion opens, said clip projecting in the free state from said end of said main body.
Claim 8
Dependent Claim
80 words
Coupling according to claim 2, wherein the sealing ring forms a single part with the anchoring clip, said part being pierced by a cylindrical axial bore having externally a cylindrical shape in the portion constituting the sealing ring, extending through a conical shape into the portion constituting the part, said part being of a thermoplastic or elastomeric material gripping at least three flat triangular radial metallic inserts externally mating with said conical shape and projecting slightly inside said axial bore.
Claim 9
Dependent Claim
33 words
Coupling according to claim 6, wherein the portion of the part constituting the sealing ring has an outer diameter slightly greater than that of the conical flare of the bore of the body.
Claim 10
Dependent Claim
31 words
Coupling according to claim 6, wherein the conical end of the part constituting the clip has an outer diameter slightly greater than the inner diameter of the bore of the body.
Claim 11
Dependent Claim
21 words
Coupling according to claim 2, wherein the clip is of a material of the group comprising plasticized polyvinyl chloride and polyurethane.
Claim 12
Dependent Claim
22 words
Coupling according to claim 2, wherein the sealing ring is of a material of the group comprising plasticized polyvinyl chloride and polyurethane.
