  • the invention can be implemented in any other application which requires a power connection of a large number of cables / wires. between them in a junction area.
  • One of the aircraft cabling operations consists in electrically connecting a large number of power cables / wires.
  • This operation is usually carried out using a screw terminal block, fixed to the structure of the aircraft, and in which the plurality of cables / electric wires are inserted and then fixed by clamping.
  • FIG. 1 An example of such an existing terminal block, generally designated by the reference 1, which is designed to connect two or more electric cables 2 equipped with lugs 20 at their ends by a screw-nut system.
  • This terminal block 1 firstly comprises an electrically insulating support 10 in which are fixed terminal screws 11 which each form, with a nut 12, a screw-nut system for tightening the terminals 20 fitted to the cables 2.
  • An electrically conductive washer 13, of corrugated washer, is provided for each screw-nut system.
  • Each terminal screw 11 passes through an electrically conductive bar 14.

  • an additional cover commonly called an “umbrella” is attached to the structure of the aircraft, above the terminal block to prevent condensed moisture from flowing directly onto cables 2 connected in the terminal block .
  • such a screw terminal block 1 has many major drawbacks.
  • the terminals 20 must be perfectly oriented to be threaded around the terminal screws 11 for a satisfactory electrical connection. Most of the time, this involves an operator having to untwist the cables 2.
  • the extra length of the cables that is to say the additional length to the nominal dimension to compensate for the variations in wiring, or conversely the underslength is difficult to manage for an operator at terminal block 1, due to the rigidity of the cables 2 which can be secured to several of them, upstream of the terminal block. This excess length is all the more penalizing for an operator when he has untwisted the cables 2.
  • the number of parts to be managed is high with, in addition, a high risk of loss of parts which therefore induces a risk of body foreign, or mechanical debris (FOD acronym for "Foreign Object Damage”) that can cause damage, which we absolutely try to avoid in the field of aeronautics.
  • the insulating support 10 is usually fixed on the side of the ceiling in the structure of an airplane.
  • a screw terminal block requires that the cables not be energized to avoid electrical risks for the operators in charge of the electrical connection. These risks cannot be completely ruled out during tests to verify correct operation.

  • the plugs 5 can also be provided with O-rings 6 at their outer periphery ( figure 30 ).
  • the figure 31 takes over the configuration of the figure 29 , but without the presence of a wall 380 forming the electric shunt: thus each conductive tube 38 electrically connecting two terminations 4 facing each other, is independent of the other tube 38.
  • the electrical connection is made between at least two electric cable terminations 4 each housed within a different cavity in the body 30 of the module, the invention can quite well be implemented with a single module cavity for accommodating a cable termination to be connected to a fixed electrically conductive element, electrically connected to the conductive tube 38.
  • connection module 3 shown comprises a single cavity 31 for an electrical cable termination 4, the conductive tube 38 being integral with an electrical connection bar or busbar B.
  • connection module in a support rail is carried out by a translation along the longitudinal axis X of the module, that is to say in the width direction of the rail, it is obviously possible to envisage a translation in a different direction, in particular a translation in a direction orthogonal to the X axis, that is to say in the direction of the length of the rail.
