Definitions

  • the present invention relates to a composite electric cable for transporting power current and / or control current.
  • a large number of devices, flying, navigating and rolling devices, mobile or stationary, household or industrial machines or installations include electrical, electromechanical or electronic components which, in the performance of their work, require some such as motors, devices lighting or warning, a relatively strong electric current supply, called power current, and others such as relays, solenoid valves, temperature gauges or semiconductor devices, a relatively electric supply low called control current.
  • power current a relatively strong electric current supply
  • control current a relatively strong electric current supply low called control current.
  • the devices with power consumption are locally grouped and controlled through local relay systems which are supplied simply with low control current and admit a single input for power current.
  • the conductors intended for power current and those reserved for control current are in a known manner grouped together in the same support in the form of a mixed ribbon for transporting power current and current. ordered.
  • An example of this simplified and simplified wiring is found in the electrical wiring of certain known motor vehicles where the organs for consuming electric power current such as ignition, lighting, warning, air conditioning devices, etc. are locally grouped together and controlled by relays or relay systems supplied simply with electric control current.
  • the mixed ribbons for transporting current, power and control current thus advantageously replace the bulky bundles of conductors which usually provide the electrical supply for these normally arranged and non-arranged electrical members. grouped together. Indeed, these bulky bundles of conductors are difficult to house and lay and risk being easily damaged.
