  • a program transmission network cable or internet access which is represented by socket 15 connected to the network 25.
  • FIG. 1a also represents a personal computer 30 provided with a modem, an answering machine 31, a telephone 32 and a television set 33, each of these devices being connected to two networks so as to form a set L of eight links.
  • the matrix below details the connections between the devices and the sockets:
  • FIG. 1b represents an assembly of known type comprising the same devices, networks and sockets as those in Figure 1a, and devices PAF placed immediately downstream of sockets 10 to 15.
  • PAF devices each include an electronic circuit allowing the earth to flow nuisance overvoltages occurring on the networks to which the taken.
  • Such protective devices for low voltage networks are good known, and will not be described in more detail in the present text.
  • the devices are here connected to the sockets via PAF devices, so as to be protected from overvoltages which may come from networks
  • a filter 40 is integrated in the strip 5 which includes a set of sockets identical to those of the figures previous.
  • This filter includes one or more circuits allowing to flow at the earth the overvoltages likely to come from different networks.
  • a housing comprising a filter of this type is also known per se, in particular by the document DE 9100130.7.
  • a sheath 45 comprising a set of cables C able to convey the network signals 20 to 25, connects the filter 40 to a box 50.
  • the devices 30 to 33 are connected to the housing 50 by means of connectors of the said housing 50 at each connection, and each connected to the cable of set C corresponding to the desired signal type.
  • the sheath 45 comprises cables capable of carrying signals of very different characteristics. According to the state of the art, the fact of make on the one hand cables transmitting high frequency signals like for example those of the telephone network 21 with cables on the other hand connected to the sector leads to power disturbances delivered by cables connected to the sector.
  • FIG. 3a is a sectional view of an embodiment of the sheath 45 and cables from assembly C.
  • Sheath 45 contains a coaxial cable C1 for the transmission of video signals, three cables forming a set C2 for the power supply, the three cables respectively corresponding to neutral, to phase and to ground, and two pairs C3 and C4 of twisted wires for the transmission of signals such as those carried by telephone lines.
  • Figures 3b to 3d are three sectional representations of variants of the sheath 45 and cables of assembly C; in these variants, we will describe more in detail the configuration of the cables of assembly C which are represented here really proportional to their practical realization.
  • FIG. 3b thus shows a first alternative embodiment in which the sheath 45 which is of realization known per se encloses around a rod J a coaxial cable C1b and three conductors for the electrical supply C21, C22 and C23.
  • the three conductors C21, C22 and C23 are intended to operate under an operating voltage of 600 volts and they have a lower line resistance or equal to 20.5 Ohms per Km.
  • the diameter of each of these three conductors is of the order of 2.1 mm.
  • the coaxial C1b has a characteristic impedance of 75 ⁇ 7 Ohms, capacity less than or equal to 90 pf / m, attenuation at 10 MHz less than or equal to 0.1 dB / m, attenuation at 200 MHz less than or equal to 0.3 dB / m.
  • the general characteristics of the cable set C in this variant embodiment are a C2 type fire resistance according to the NFC standard 32070, a service temperature ranging from -15 to + 70 ° centigrade, a radius of static curvature greater than or equal to 65 mm, a dynamic radius of curvature greater than or equal to 120mm, a weight of 0.11km per meter and a diameter 8 ⁇ 0.3mm outside.
  • FIG. 3c shows a second alternative embodiment of all the cables C in which the sheath 45 here again comprises three conductors C21, C22, C23 identical to those of FIG. 3b, as well as a ribbon R of polymer shielding, the internal face is coated with aluminum, said strip containing two conductors C31 and C32 of 0.25 mm 2 made of insulated extra-flexible tinned copper, with an outside diameter of the order of 1 mm and an electrical continuity wire F which is located in contact with the aluminized side of the tape.
  • the total outside diameter of the cable is of the order of 7.4 ⁇ 0.3 mm.
  • Figure 3d represents a third variant in which we gathered around a central rod three conductors for food electric, two coaxial cables identical to the cable C1b in Figure 3b and one assembly contained in an aluminized shielding tape as shown in the figure 3c.
  • the diameter total outside of the cable is around 9.2 ⁇ 0.2mm.
  • the shields used in the cable assemblies described above if they guarantee normal functioning of the networks, do not guarantee protection against interference between cables due to overvoltages. Placing upstream of the cable assembly C a overvoltage elimination device therefore allows cables to carry under good conditions different signals in a confined space.
  • the cable assembly C and the sheath 45 can be produced using known materials, such as in particular those described in the catalogs of manufacturers like Pirelli (reference EV6 M AE 2X0.75 + 6 * 0.22) or Filotex (study cable reference N ° 38327), for example.
  • Figure 2b shows a second embodiment of the invention.
  • the devices are no longer connected here to a single box 50, but to modules M1 to M8 each of which has the connector corresponding to the desired link.
  • a sheath 45 comprises a set of cables for transmit all the signals necessary for the operation of the devices.
  • This set of cables leads to a first connection module M1 for the connection of computer 30 to the mains via the cable from assembly C connected to the socket 11.
  • the module M1 is connected to a second module M2 by a connection 60 which transmits all the signals carried by the cables of assembly C.
  • This connection 60 can consist of a set of cables similar to those of assembly C connected to the cables of assembly C by contact pads, a electrical connector capable of receiving a connection plug from the computer 30 being connected to the pad of the cable of the assembly C connected to the sector.
  • connection 60 can also be made in the form of a pin connector, suitable for carrying all the signals from set C.
  • a such a connector can use for example as illustrated in FIG. 4a a circuit printed with identical conductive tracks 70 each connected to one of the cables from assembly C.
  • Such a connector can in another embodiment shown in Figure 4b include cells dedicated to the connection for a type of specific signal.
  • the two cells 71 and 72 are thus dedicated to the connection of cables C3 and C4 in FIG. 3, and the cells 73 and 74 are dedicated to the connection of a coaxial cable and power supply cables, respectively.
  • the different cells of the connector can be metallized so as to form a ground plane in order to avoid interference between alveoli.
  • the connector includes a printed circuit board and tracks on pins specifically dimensioned the connection of selected signals or the supply by the sector.
  • the module M2 is provided with a connector to connect the modem of computer 30 to the telephone network.
  • connection 60 it is thus possible according to the invention to connect as many modules as desired, each module being connected to the previous one by a connection similar to the connection 60 and comprising in this embodiment a connector of the type particular for connecting a device to one of the cables in assembly C.
  • the filter 40 can, instead of being integrated in the strip 5, be incorporated in a separate box from the headband. Said housing is then connected by wire connections to different networks via fixed sockets 10 to 15, or connected to cables C of the sheath 45, said sheath coming directly from strip 5.
  • the filter 40 comprises, in addition to circuits for clipping overvoltages, signal filtering means in frequency and / or in phase and / or other characteristics according to any process known, in order to guarantee the quality of the signals transmitted by the entire cable C to devices.
  • certain cables of the set C can transmit several signals of types simultaneously different.
  • the sheath 45 can thus according to the invention contain fewer cables than of networks to which the device is connected. Transmission of at least two types different signals by a single cable then uses according to techniques known means of input modulation, multiplexing, and demodulation in output of the various signals carried by the cable. In this variant, it is also possible to combine all signals on a single cable.
