Abstract
Abstract A device to join up cable sheathings comprises a chamber and a shaft. The shaft houses the cable and is connected in an electromagnetically impervious way to a rear part of the chamber. A front part of the chamber is itself designed to be connected in an electromagnetically impervious way to a casing, for example a connector casing. The conductive surface providing for the impervious electrical continuity between the periphery of the shaft and periphery of the chamber is outside the chamber. This makes it possible to give the internal diameter of the shaft a value that is substantially equal to that of a casing to which the front part of the chamber must be connected.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
210 words
A device for sheathing ends of a strand of sheathed cables, where said ends are inserted into a sheathing casing, the device comprising: a chamber having an axis and two ends along the axis including a front end close to the ends of the cables and a rear end at a distance from the ends of the cables, the chamber having an internal surface which demarcates an internal volume of the chamber; a single shaft having the same axis as said chamber and two ends along said axis including a front end close to the ends of the cables and a rear end at a distance from the ends of the cables, said shaft having an internal surface and an external surface, with the internal surface of the shaft demarcating a volume for housing part of the strand; a means of contact between the shaft and the chamber for ensuring electromagnetic imperviousness at the rear end of the chamber, said means of contact being in continuous electrical contact throughout a periphery of the shaft and also in continuous electrical contact throughout a periphery of the chamber, the external perimeter of said means of contact being greater than an internal perimeter of the chamber in a plane perpendicular to said axis.
Claim 2
Independent Claim
210 words
A device for sheathing ends of a strand of sheathed cables, where said ends are inserted into a sheathing casing, the device comprising: a chamber having an axis and two ends along the axis including a front end close to the ends of the cables and a rear end at a distance from the ends of the cables, the chamber having an internal surface which demarcates an internal volume of the chamber; a single shaft having the same axis as said chamber and two ends along said axis including a front end close to the ends of the cables and a rear end at a distance from the ends of the cables, said shaft having an internal surface and an external surface, with the internal surface of the shaft demarcating a volume for housing part of the strand; a means of contact between the shaft and the chamber for ensuring electromagnetic imperviousness at the rear end of the chamber, said means of contact being in continuous electrical contact throughout a periphery of the shaft and also in continuous electrical contact throughout a periphery of the chamber, the external perimeter of said means of contact being greater than an internal perimeter of the chamber in a plane perpendicular to said axis.
Claim 3
Dependent Claim
43 words
A device according to claim 1, wherein at least one cross-section of the chamber located close to the front end has an internal diameter smaller than that of a cross-section of the internal surface located close to the rear end of the chamber.
Claim 4
Dependent Claim
20 words
A device according to claim 1, wherein the rear end of said chamber has a cylindrical shape generated by revolution.
Claim 5
Dependent Claim
15 words
A device according to claim 1, wherein the chamber is provided with an external thread.
Claim 6
Dependent Claim
36 words
A device according to claim 1, wherein the shaft is provided with a shoulder projecting radially to the external surface of the shaft, this shoulder constituting the means of contact between the chamber and the shaft.
Claim 7
Dependent Claim
23 words
A device according to claim 5, wherein the shaft, at least at the shoulder, has a shape generated by revolution around the axis.
Claim 8
Dependent Claim
29 words
A device according to claim 5, wherein a part of the shaft located outside the chamber comprises two notches enabling housing, at least partially, of the cable fastening lugs.
Claim 9
Dependent Claim
79 words
A device according to claim 1, wherein the contact means comprise sector shells together having substantially the shape of a flat washer, having a front surface, a rear surface, an internal lateral surface and an external lateral surface, the internal lateral surface of the washer thus formed being in electrical contact with the external surface of the shaft, at least a part of the front surface being supported on the rear surface of the rear end of the chamber.
Claim 10
Dependent Claim
59 words
A device according to claim 8, wherein the washer formed by the set of the shells has a front part, of which at least a part of the external lateral surface is in contact with the internal lateral surface of the rear end of the chamber to provide for a positioning of the shaft with respect to the chamber.
Claim 11
Independent Claim
41 words
A device according to any of the claims 5 to 9, wherein the shaft and the chamber are held in a joined state by means that exert a pressure directed frontwards on a rear part of the shoulder of the shaft.
Claim 12
Dependent Claim
29 words
A device according to claim 8, wherein the means that enable the pressure to be exerted consist of a nut screwed on to the threaded part of the chamber.
Claim 13
Dependent Claim
28 words
A device according to claim 7, wherein the device further comprises clamping lugs which, in cooperation with notches of the shaft, enable the holding of a cable strand.
