Abstract
Abstract A cable joint comprising a pair of end bodies and a longitudinally slotted sleeve which is secured on the end bodies with a sealing system arranged therebetween characterized by the sealing system having two annular portions and at least one longitudinal portion and an arrangement for clamping the sleeve in sealing engagement on the end bodies. Preferably, the sealing system is reusable and the assembly can be accomplished with ordinary tools such as a screwdriver. In one embodiment, the annular portions are separate from the longitudinal portions. In another embodiment, a single ring-shaped element forms both the annular portions and the two longitudinal portions.

Claims Analysis
Total Claims: 24
Claim 1
Independent Claim
205 words
In a cable joint having a pair of end bodies with sealing glands for cables extending therethrough and a sleeve having a longitudinally extending slot with two edge portions, said sleeve being wrapped around the spaced apart end bodies and held there by a closing means engaging said sleeve, the improvements comprising an internal member extending between a periphery of one end body and a periphery of the other end body and being adjacent said slot, and a sealing system having a single, continuous endless ring sealing element having two longitudinal sealing portions and two annular sealing portions, said sealing element being positioned with an annular portion being disposed between a periphery of each end body and the sleeve and the two longitudinal sealing portions being positioned between the internal member and the two edge portions of the sleeve, means for holding the member and edge portion in a clamped engagement on the longitudinal portions of the sealing system to seal the slot, said sealing element being of an elastic material constructed to be sufficiently flexible so that the closing means and closing elements can be constructed as simple as possible and can be actuated by utilizing conventional tools for obtaining the necessary closing pressure.

Claim 3
Dependent Claim
19 words
In a cable joint according to claim 1, wherein the endless ring sealing element has a solid cross section.
Claim 4
Dependent Claim
25 words
In a cable joint according to claim 2, wherein the endless ring sealing element has at least one lip extending the length of said ring.
Claim 5
Dependent Claim
20 words
In a cable joint according to claim 1, wherein the endless ring sealing element is provided with a bonding agent.
Claim 6
Dependent Claim
19 words
In a cable joint according to claim 1, wherein the endless ring sealing element has a tubular cross section.
Claim 7
Dependent Claim
45 words
In a cable joint according to claim 5, wherein the tubular sealing element forming the ring has an approximately rectangular basic cross section, with two side walls being concave side walls so that when the sealing element is compressed, a preferred bending direction is obtained.
Claim 8
Dependent Claim
43 words
In a cable joint according to claim 6, wherein the tubular sealing element has at least one opening directed into the interior of the cable joint to enable transfer of pressure from the tubular sealing element and the interior of the cable joint.
Claim 9
Dependent Claim
56 words
In a cable joint according to claim 6, wherein the walls of the rectangular cross section are selected so that during compression of the sealing element, it exhibits a spring characteristic with a linear pressure rise and then has a substantially uniform pressure characteristic during further collapsing of the element up to a maximum closing pressure.
Claim 10
Dependent Claim
23 words
In a cable joint according to claim 5, wherein the interior of the tubular sealing element is subjectable to an excess in pressure.
Claim 11
Dependent Claim
24 words
In a cable joint according to claim 9, wherein the sealing element includes a valve for regulating the pressure in the tubular sealing element.
Claim 12
Dependent Claim
19 words
In a cable joint according to claim 9, wherein the tubular sealing element is connected to a compressible container.
Claim 13
Dependent Claim
20 words
In a cable joint according to claim 1, wherein the endless ring sealing element is provided with an impermeable coating.
Claim 14
Dependent Claim
32 words
In a cable sleeve according to claim 1, wherein at least one of the internal member, end bodies and the sleeve has a groove for receiving a portion of the sealing element.
Claim 15
Dependent Claim
78 words
In a cable joint according to claim 1, wherein the internal member is a connecting bar extending between the end bodies, said connecting bar having grooves for supporting the longitudinal portion with a ridge disposed between the two grooves, said grooves adjacent each end body merging together so that the longitudinal portions are held apart by the ridge along the slot and merge into sealing engagement with each other at each end body and adjacent the annular portion.
Claim 16
Dependent Claim
78 words
In a cable joint according to claim 1, wherein the means for holding comprises a split flange adjacent each of the edge portions of the sleeve, a matching clutch bar for engaging the surface of the split flange and pressing them close together, and means extending from said clutch bar to hold the internal member to press the longitudinal portions of the sealing system against the inner surface of the sleeve adjacent said flanges to form said seal.
Claim 17
Dependent Claim
65 words
In a cable joint according to claim 1, wherein the means for holding includes the sleeve having sub-flanges with one sub-flange having a hook portion for engaging the other sub-flange and bolt means extending from said hook portion to engage the inner member to hold the longitudinal portions of the sealing system tightly against an interior surface of the sleeve adjacent each of said flanges.
Claim 18
Dependent Claim
35 words
In a cable joint according to claim 1, wherein edge portions of said sleeve have flanges with one of the flanges having a longitudinally extending groove receiving a longitudinally extending projection of the other flange.
Claim 19
Dependent Claim
