- the present invention relates to a terminal device for shielded cable with mineral insulation which offers good hermeticity and very good dielectric strength, several thousand volts, at high temperature, in particular up to 1000 ° C.
- the shielded cables with mineral insulation are cables consisting of a central metal conductor and a cylindrical hollow metal sheath between which is introduced a refractory insulating powder such as mineral type magnesia, alumina or silica, the outer sheath being made of stainless steel, copper or an Ni-Cr alloy such as that known under the trade name Inconel 600.
- a refractory insulating powder such as mineral type magnesia, alumina or silica
- the outer sheath being made of stainless steel, copper or an Ni-Cr alloy such as that known under the trade name Inconel 600.
- Such cables are fire resistant and are used in places which can accommodate the public such as shopping centers, airports, reception rooms, or in industrial environments comprising risk areas such as nuclear power plants. They are used in particular in many areas of industry in which sensors, heating elements or cables for transmitting electrical signals are used which must withstand environments presenting increasingly severe conditions (temperature, high voltage, etc. humidity,).
- Such cables thus serve to connect devices spaced from one another and it is therefore necessary to provide means for connecting these cables to the devices, or even cables between them.
- the cable terminal devices and more generally the connectors are extremely critical parts of these components since they must ensure the electrical continuity of the conductors, prevent the migration of humidity into the insulation while preserving the dielectric strength of the cable .
- a shielded cable can therefore be an electric heating element or a signal transmission cable with mineral insulator of the magnesia, alumina or silica type and with an outer sheath of stainless steel, copper or an Ni-Cr alloy.
- FR-A-1 150390 an accessory making it possible to insulate an electric cable, consisting of two ceramic plugs having respectively one end in the form of a cone and connected to each other by a glass seal. These two caps are housed in a metal tube and have a central through bore in which the conductor of the cable can be accommodated.
- the electric cable consists of a central conductor, housed in an outer sheath, a hygroscopic mineral insulator being placed between the outer sheath and the central conductor.
- the mineral insulator at the end of the cable has an annular cavity of conical shape in which is housed a conical end of a ceramic plug constituting an insulator.
- the latter consists of two ceramic caps linked to a glass seal, these two caps being housed in a metal sheath.
- the tapered end of the insulator fits into the tapered cavity of the cable end while the metal sheath of the insulator is welded to the outer sheath of the cable.
- a coupling sleeve of cylindrical shape comprising a first inlet which can be mounted on the outer periphery of the metal sheath of a first mineral insulated cable and a second end mounted on the outer periphery of a second cable or of a complementary device, the sleeve thus mounted is directly welded to the external periphery of the connected elements.
- the sleeve thus forms a cavity in which the electrical conductors are connected.
- the sleeve has an opening allowing said cavity to be filled with an insulating material.
- Document US Pat. No. 9,583,933 proposes a mineral insulated cable termination device comprising a conductive element forming a rod and comprising a receiving cavity of the electrical conductor corresponding to a stripped end of the cable, the rod s 'engaging around the conductor into the cable itself.
- a sealing ring is also placed between the metal rod and the mineral insulation contained in the sheath.
- the metal rod is placed an insulating sleeve. To prevent moisture from corrupting the mineral insulation, the end is heated during assembly.
- the sealing ring is inserted between the mineral insulator and the electrical conductor after having removed a part of the mineral insulation around the conductor or the end of the termination device is tapered to wedge itself. in the mineral insulation.
- Such a device also requires O-rings to ensure airtightness, which limits use at high temperatures. The waterproofing can therefore deteriorate over time due to the aging of the materials, moisture can enter, etc.
- terminal devices of the type hermetic glass-metal feedthroughs which typically withstand 500 ° C or ceramic-metal having a resistance up to 1000 ° C.
- this type of connector requires the ceramic insulation to be exposed. and the conductor of the cable during stripping, thus leaving the possibility for an electric arc to form in service between the conductor and the shielding. This risk is all the greater when the cable operates at high voltage (for example for a shielded heating element or a signal transmission cable connected to specific detectors). High voltages are then not applicable permanently.

- the end of the sleeve intended to be mounted on the outer periphery of the cable can be fixed to the outer sheath of the cable by crimping.
- the end of the socket has fixing means intended to cooperate with complementary fixing means provided at the outer periphery of the end of the cable, the cooperation of the socket / cable preferably making it possible to generate the compressive force exerted by the tapered tip of the cylinder on the mineral insulation.

- the inorganic insulation of the cable and the ceramic insulating element remain in compression, thus offering a dielectric barrier to the cable, even under high temperature conditions.
- a socket / sleeve assembly can accommodate several ceramic insulating elements and associated metal tubes, all of which can be accommodated in said socket / sleeve assembly but respectively having a bore adapted to a different conductor diameter. These different conductor diameters generally lead to different cable diameters and in this case, the threaded ring cooperating with the sleeve is adapted to the diameter of the cable.
- a terminal device whether in the termination or connector mode, therefore makes it possible to obtain a cable with a device sealed in particular by high-temperature solder and perfectly hermetic without there being any organic materials. no seal, and only with metal and ceramic.

- This sleeve 3 or base (or fitting) is soldered onto the ceramic insulating element 4.
- This type of termination can be qualified as monobloc.
- the socket 3 has an end for fixing to the end of the cable 2, in particular by positioning itself around the outer sheath 22.
- the socket 3 has means for fixing to the cable 2.
