Definitions
- the present invention relates to an electrical connection piece comprising a protective sleeve intended to come into contact with one end of a semiconductor screen of an electrical cable.
- medium or high voltage electric cables generally comprise a conductive core covered with an insulating layer itself covered with a semiconductor screen in contact with a metal shielding that is connected to earth and covered with a sheath external.
- the end of the semiconductor screen performs a step relative to the insulating layer of the cable and the simplest solution for putting the conductive or semiconductive layer of the protective sleeve in connection with the end of the semi-screen -conductor would consist in putting the end of the sleeve in abutment on the end of the semiconductor screen.
- the protective sleeve is generally associated with other elements which are positioned relative to the end of the conductive core or the end of the insulating layer of the cable so that the end of the protective sleeve relative to the semiconductor screen can only be obtained if to cut the semiconductor screen at a very precise distance from the end of the conductive core or of the insulating layer, which is difficult to achieve on a site.
- pressing the end of the protective sleeve on the end of the semiconductor screen of the cable would not ensure good sealing between the connection piece and the cable.
- the protective sleeve In order to ensure a connection between the protective sleeve and the end of the semiconductor screen, provision is therefore generally made for the end of the semiconductor screen to be covered by the protective sleeve over a distance which is several times the thickness of the semiconductor screen. To ensure good contact between the protective sleeve and the semi-conductive screen of the cable, it is desirable that the protective sleeve is made of an elastic material having at rest a diameter slightly less than the external diameter of the semi-conductive screen of the cable. cable.
- the end of the semiconductor screen forms a step with respect to the insulating layer so that the end of the protective sleeve tends to come into abutment on this step during of its implementation.
- this step it has been envisaged to have a conical piece on the cable before the fitting of the connection piece.
- an electrical connection part comprising a connection member. conductive layer, a conductive inner layer surrounding the connection member, an insulating layer surrounding the conductive sheath, and an elastic protective sleeve which, when at rest, comprises at least one cylindrical part adjacent to one end of the insulating layer and a conical part which is adjacent to the cylindrical part and widens from the cylindrical part, the protective sleeve further comprising at an end opposite to the cylindrical part an orifice having a diameter greater than the cylindrical part.
- the conductive sheath of which has a diameter slightly greater than the diameter of the cylindrical part of the protective sleeve the larger diameter of the orifice of the protective sleeve allows 'engage it on the cable and the conical part of the protective sleeve serves as a ramp to allow an elastic fitting of the cylindrical part of the protective sleeve on the semiconductor screen of the cable when the connecting piece is pushed axially to engage the end of the cable.
- the sleeve has a conical part which is adjacent to the orifice and has a diameter which decreases towards the latter.
- FIG. 2 is an axial sectional view of a connecting piece of Figure 1 placed on a cable.
- connection piece according to the invention is intended to be placed on an electric cable which comprises, in a manner known per se, a conductive core 1 covered with an insulating layer 2 which is cut during the preparation of the cable set back from the end of the conductive core 1 to release this end, a semiconductor screen 3 which covers the insulating layer 2 and is sectioned back from the end of the insulating layer 2, a metal shield 4 and an outer sheath 5 which are sectioned back from the end of the semiconductor screen 3.
- the earthing of the semiconductor screen 3 and of the metal shield 4 is provided by a metal ring 6 which is slid under the end of the metal shield 4 and is connected to a metal braid 7 suitably connected to the earth potential in a manner not shown.
- the illustrated electrical connection part is a plug-in socket which is produced in a prefabricated molded piece and comprises a conductive connection member 8 intended to be crimped onto the end of the conductive core of the cable, a layer internal conductive 9 which surrounds the connection member and is intended to cover the end of the insulating sheath 2 of the cable while being in contact with the latter, an insulating layer 10 which covers the internal conductive sheath 9, and a protective sleeve elastic generally designated at 11 which is formed of a single layer of conductive or semiconductor rubber.
- the protective sleeve 11 covers the insulating layer 10 and extends beyond it.
- the protective sleeve portion tor 11 which extends beyond the insulating layer 10 comprises at rest a cylindrical part 12 adjacent to the end of the insulating layer 10, a conical part 13 which is adjacent to the cylindrical part 12 and widens from the cylindrical part 12 towards the free end of the protective sleeve 11, a cylindrical part 14 connected to the larger diameter part of the conical part 13, and a conical part 15 tapering towards an orifice 16 at an opposite end to the cylindrical part 12.
- the cylindrical part 12 has a diameter slightly less than the diameter of the semiconductor screen
- the orifice 16 has a diameter greater than that of the cylindrical part 12 and preferably slightly greater than the diameter of the semiconductor screen 3 of the cable on which the connection piece is to be mounted.
- grease is preferably placed inside the protective sleeve 11 and on the external surface of the insulating layer 2 of the cable.
- the opening 16 of the protective sleeve is easily engaged on the end of the cable and the grease facilitates the introduction of the sleeve on the insulating layer. 2 until the conical part 13 comes to bear on the end of the semiconductor screen 3.
- the cylindrical part 13 then serves as a ramp resting on the end of the semiconductor screen 3 to cause a flaring of the cylindrical part 12 which thus comes into close contact with the end of the semiconductor screen
- a protective sleeve comprising a cylindrical part 14 extending between the conical part 13 and the conical part 15 to ensure overlap of the sealant 17 over a length relatively large
- a protective sleeve can be provided comprising a conical part 15 directly connected to the conical part 13 or having a section in an arc of a circle between the cylindrical part 12 and the end orifice 16.
- the invention has been described in relation to a connection piece in the form of a plug-in socket, the invention also applies to a junction of two cables, the protective sleeve 11 then being produced symmetrically with respect to a tubular conductive member opening out towards the two ends of the protective sleeve 11, each end of the protective sleeve 11 comprising a cantilevered part having the characteristics set out above .
