  • the projecting elements 523a can be arranged on the internal surface of the secondary channel 520a ( Figures 18a and 18b ). Alternatively, illustrated in figure 19 , the projecting elements can be arranged on a ring 529 of shape complementary to the secondary channel 520a and inserted into said channel.
  • the anchoring means 523 can be an integral part of the electrical connection means 600 and in particular be arranged on a secondary contact section 620.
  • the main channel 510a can comprise, on its internal surface, protrusions, called main protrusions 524, intended to guide the main conductor 210 ( figure 20a ).
  • the figure 21a represents the assembly of secondary conductors 310 with connectors 500, and in particular connectors therefore the secondary channel 520a is provided with a secondary stop 521.
  • This step is then followed by the mounting of the main conductor 210 in the main channels 510a of the connectors 500 ( figure 21b ).
  • the figures 22a to 22c and 23 illustrate the detachment of a drop cable 300 from the multi-conductor electric cable 100.
  • figures 22a and 22b represent the cutout of the termination 330.
  • the termination can be pre-weakened, and according to this condition, a simple tearing effort must be sufficient to initiate the detachment of the branch cable. Otherwise, for example in the presence of a core common to all the secondary conductors or in the presence of a connector 500 provided with a contraction zone separating the first volume and the second volume, it may be necessary to cut the termination 330 using a cutting pliers 800 as illustrated in the figure 23 .
  • the cutting is then followed by a detachment of the branch cable 300 according to the isolation section 110 ( figure 22c ).
  • the cutout is naturally stopped at the connector 500 which offers greater resistance to tearing.
  • the present invention also relates to an assembly of multi-conductor electric cables 100 ( figure 10 ).
  • the assembly comprises in particular a plurality of multi-conductor electric cables 100 comprising a common coating sheath, and electrically insulated from each other by said common sheath.
  • the assembly can be flat ( figure 11a ) or star ( figure 11b ).
  • the multi-conductor electric cable and / or the assembly devoid of ramifications and of relatively constant section, can advantageously be used to establish electrical connections in confined spaces.
  • a multi-conductor electric cable according to the present invention is also advantageously used for electrical distribution, in particular for external networks requiring tight connections at a reasonable cost and / or difficulty.
  • These cables can also be used for the electrical connection of solar panels, wind turbines.
