Definitions

  • the present invention relates to electrical control cables, or power cables, used to transmit currents.
  • Such cables are used in various fields of the industry, such as for example the automotive industry, where they are assembled into bundles for the power supply of different equipment. These cables must thus be the lightest possible, and have a small footprint while maintaining good mechanical strength.
  • Such cables are conventionally formed by a plurality of copper strands, generally twisted to form a strand so as to increase the flexibility of the cable, and surrounded by an insulating sheath, obtained for example by extrusion.
  • the figure 1 shows an example of such a cable 1, seen in cross section, and made from seven identical copper strands 20 surrounded by an insulating sheath 30 of circular section.
  • the diameter of the cable is typically of the order of 1.6 mm and the copper strands 20 each have a diameter of the order of 0.3 mm.
  • the preceding cable uses a quantity of copper that is oversized compared to the real needs corresponding to the quantity of current to be transmitted by the cable. More precisely, almost half of the copper in the previous cable structure is used to increase the tensile strength of the cable, but also to ensure the effectiveness of crimping.
  • This type of cable can significantly reduce the amount of copper used to the value just necessary for good signal transmission, while maintaining a very good mechanical strength to traction through the use of aramid.
  • the aramid has a very high tensile strength compatible with the required values, this type of material has a low level of elongation at break, typically of the order of 3%. These characteristics are shown on the tensile curve 1 of the figure 2 illustrating the tensile force required as a function of elongation for the aramid.
  • the present invention relates to a composite control cable comprising a polymer core and a plurality of strands of an electrically conductive material extending in the longitudinal direction of the cable around said core, characterized in that the polymer is chosen from polymers having an elongation rate greater than 7%, and a tensile strength such that the resulting tensile strength of the cable is greater than a predetermined limit value.
  • the tensile curve of an example of such a polymer is shown schematically as 2 of the figure 2 . It is found that the tensile force of the selected polymer varies linearly with the rate of elongation, preferably with a slight slope. In this way, it is possible to easily obtain an elongation of the cable, exerting a minimum tensile force.
  • the tensile curve 1 'of the cable is the resultant of the tensile curve 2 of the polymer core alone, and of the tensile curve 3 of the strands of electrically conductive material, in the copper example.
  • Point A on this curve 1 ' represents the tensile strength of the minimum required cable, to obtain the desired minimum elongation ratio of 7%.
  • a polymer selected according to the invention such as a PEN (polyethylene naphthalate), a polyester (PES), or a polyethylene terephthalate (PET), it was possible to obtain tensile strengths greater than a limit value of the order of 70 N, corresponding to the requirements generally in the field of the automotive industry, using polymers having a tensile strength much lower than that of the aramid.
  • PEN polyethylene naphthalate
  • PET polyethylene terephthalate
  • the polymer core preferably has a diameter between 0.2 and 0.3 mm.
  • the number of copper strands used, for example by forming a twist, around the core is preferably chosen to continuously surround the entire circumference of the heart. Indeed, in this case, the copper strands are always in contact two by two along the entire length of the cable, which increases the reliability of crimping operations of connectors on the cable ends.
  • the diameter of the polymer core is 0.3 mm, it will be advantageous to use nine copper strands of 0.16 mm diameter each. If the diameter of the core is 0.2 mm, six copper strands of 0.2 mm in diameter will advantageously be used. In both cases, a cable is obtained whose quantity of copper has been substantially reduced compared to the seven-stranded copper cable shown below, with mechanical performance and similar bulk.
  • the present invention has been described in the context of a cable using copper strands, it can be applied regardless of the electrically conductive material used for the strands surrounding the polyamide core (copper alloy, aluminum or aluminum alloy). aluminum among others).
