Abstract
Abstract This device for the fluid-tight anchorage of an electric conducting cable, for example through an inlet aperture formed in a cabinet, box or the like, comprises a tubular body through which the cable is passed, such body consisting of two sections adapted to be screwed onto each other. One of these sections includes the one means such as a packing ring for sealing the cable inlet and the other section includes means such as a socket formed with radial longitudinal slots for anchoring the cable inlet. The packing ring and the socket face each other so that, when the body sections are tightened by screwing, the ring and socket engage each other, and consequently the action exerted on the ring and on the socket by their interaction is reinforced by this tightening movement.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
300 words
A device for the simultaneous sealing and anchoring of an electric conducting cable in an inlet of a structure, said device comprising: a tubular body through which an electric cable is to be passed, said body including first and second sections having mutually engageable threads so that said sections may be moved relatively axially of each other; said first section having positioned inwardly thereof flexible, sealing ring means for, upon axial movement of said sections toward each other, sealing radially inwardly against the electric cable; said second section having positioned inwardly thereof anchor means for, upon axial movement of said sections toward each other, clamping radially inwardly against the electric cable, said anchor means comprising a socket formed of flexible material and having therein a plurality of circumferentially spaced, radially and axially extending slots; said sealing ring means and said socket being in axial end-to-end relationship to each other such that, upon axial movement of said sections toward each other, said sealing ring means and said socket are moved into direct end-to-end engagement with each other; and said second section and said socket having means for, upon axial movement of said sections toward each other, simultaneously reinforcing the sealing action on said sealing ring means and the clamping action on said socket by the interaction between said sealing ring means and said socket due to end-to-end engagement therebetween, said reinforcing means comprising a bevelled end face on said second section, a bead extending outwardly from said socket, and a first bevelled surface on said bead, said first bevelled surface facing said bevelled end face and being contacted thereby upon axial movement of said sections toward each other, and the tapers of said first bevelled surface and said bevelled end face being different when out of mutual engagement with each other.
Claim 2
Independent Claim
300 words
A device for the simultaneous sealing and anchoring of an electric conducting cable in an inlet of a structure, said device comprising: a tubular body through which an electric cable is to be passed, said body including first and second sections having mutually engageable threads so that said sections may be moved relatively axially of each other; said first section having positioned inwardly thereof flexible, sealing ring means for, upon axial movement of said sections toward each other, sealing radially inwardly against the electric cable; said second section having positioned inwardly thereof anchor means for, upon axial movement of said sections toward each other, clamping radially inwardly against the electric cable, said anchor means comprising a socket formed of flexible material and having therein a plurality of circumferentially spaced, radially and axially extending slots; said sealing ring means and said socket being in axial end-to-end relationship to each other such that, upon axial movement of said sections toward each other, said sealing ring means and said socket are moved into direct end-to-end engagement with each other; and said second section and said socket having means for, upon axial movement of said sections toward each other, simultaneously reinforcing the sealing action on said sealing ring means and the clamping action on said socket by the interaction between said sealing ring means and said socket due to end-to-end engagement therebetween, said reinforcing means comprising a bevelled end face on said second section, a bead extending outwardly from said socket, and a first bevelled surface on said bead, said first bevelled surface facing said bevelled end face and being contacted thereby upon axial movement of said sections toward each other, and the tapers of said first bevelled surface and said bevelled end face being different when out of mutual engagement with each other.
Claim 3
Dependent Claim
47 words
A device as claimed in claim 1, wherein said first bevelled surface is tapered at an angle of approximately 30° to a plane extending transverse to the axis of said body, and said bevelled end face is tapered at an angle of approximately 45° to said plane.
Claim 4
Independent Claim
39 words
A device as claimed in claims 1 or 2, further comprising a second bevelled surface on said bead at a position facing said sealing ring means and in contact therewith when said sections are moved axially toward each other.
Claim 5
Dependent Claim
48 words
A device as claimed in claim 3, wherein said second bevelled surface is tapered at an angle of approximately 20° to a plane extending transverse to the axis of said body, when said socket is out of mutual engagement with the end surface of said sealing ring means.
Claim 6
Dependent Claim
48 words
A device as claimed in claim 1, wherein said second section has therein a recessed axially extending bore within which is positioned said socket, said bore having an axial dimension sufficient to enable axial movement therein of said socket during axial movement of said sections toward each other.
