Definitions

  • the present invention relates to conductor bundles electric, especially those called harnesses, which are hardened, that is to say shielded against electromagnetic disturbances, and which are intended to connect electrically between them the different devices of an electrical installation complex, whose proper functioning must be ensured, even in the event of electromagnetic interference.
  • harnesses are, for example, used on board aircraft, ships, tanks, etc ...
  • This the invention also relates to a method for producing of such a harness or harness.
  • harnesses consist of a bundle of conductors, stranded or not, divided into several sub-bundles or branches, from branching nodes arranged along said bundle and connectors arranged at the free ends of said branches.
  • said harnesses are coated with elements of metal sheath completely covering said conductors.
  • a shielding sheath has the disadvantage, in particular under the effect of the vibrations to which are subject to said harnesses, to exercise an action abrasive on objects in contact with it. So she can wear the electrical insulation covering the conductors that it surrounds. It is obvious that such an abrasive action may cause unwanted dysfunctions of installations comprising said harnesses.
  • EP-A-0 397 063 describes a bundle of multi-branch electrical conductors, provided an electromagnetic shielding system which consists of a network of metallic sheath elements surrounding said conductors and ensuring electrical continuity said shielding system, as well as a network of elements braid made of filaments of material resistant to wear and intended for the protection of said conductors electric against wear due to friction to be exerted by said metal sheath elements.
  • said protective braid elements against wear coat said conductors and said elements of metal sheath consist of metal tubes profiles, for example of the type having a rib protruding spiral.
  • the object of the present invention is to improve a bundle of electrical conductors of the type mentioned above.
  • this metal sheath is further prevented from exercising a wear action on the objects with which it can be in contact and vice versa.
  • filaments constituting said elements of protective braid can be of any kind, as long as they resist the abrasive action of the metal sheath, it is preferable that these filaments consist of a synthetic material, in particular hot melt.
  • said filaments may be present in the form of a wire, twisted or not, or else a wick of filaments (roving).
  • said bundles of electrical conductors generally have knots joining each three branches of said bundle.
  • three braid elements are formed each of which passes from one of the three branches to one of the other two being laterally crossed by the other of said two other branches and the pair of branches carrying each of said three braid elements is different couples of branches carrying the other two elements braid.
  • said first, second and third elements of braid can cover, respectively, all of said branch having the smallest section, all of said branch having the intermediate section and all of said branch having the largest section and, partially, near said node, said branch having the most strong section, said branch having the lowest section and said branch having the intermediate section.
  • said braiding tails can be used to block in position the beginning and / or the end of said braid elements on the harness of electrical conductors. This is enough effect of providing hoops or the like for securing said braiding tails on the harness. Alternatively, some braiding tails can be locked in position by one of the braid elements that covers them.
  • the realization of said braid elements is preferably carried out from the thinnest branches to larger branches.
  • Figure 1 shows a portion of a bundle of conductors electric, in the vicinity of a node connecting three branches.
  • Figure 2 shows, in cross section and at larger scale as in Figure 1, a bundle of electrical conductors known, provided with a metal shielding sheath electromagnetic.
  • FIGs 3, 4 and 5 respectively illustrate, in sections transverse similar to that of Figure 2, three modes for the bundle of electrical conductors according to the present invention.
  • FIGS 6A to 6E schematically illustrate different steps of an example implementation of the production of protective braid elements at the Figure 1 node, in accordance with the present invention.
  • FIGS 7 and 8 illustrate alternative embodiments braid elements.
  • Figure 9 illustrates the realization of a braid element near a connector.
  • Figure 10 shows the formation of an interruption in the protective braiding.
  • FIG. 11 illustrates an example of implementation of the present invention for protecting a harness of conductors by making protective braid elements, in accordance with the present invention.
  • Figure 12 shows another example of a harness that could to be protected in accordance with the invention.
  • FIG. 1 a portion of a beam F has been represented. of electrical conductors C, stranded or not, in the vicinity a node N connecting three branches B1, B2 and B3 of said beam F.
  • each branch thereof we surrounds each branch thereof with a sheath EG element metallic G protecting the corresponding conductors C, against external electromagnetic interference.
  • Such metallic sheath EG elements can be produced previously in the form of braid portions, then strung on said branches B1, B2 and B3 and finally connected electrically to each other by sleeves, by heat shrinkable example, at the N nodes, so ensure the electrical continuity of said metal sheath G.
  • each EG element of metal sheath can be braided directly on each of said branches B1, B2 and B3 and include an extension over another branch used to ensure the electrical continuity of the sheath. For this latter purpose, provision can also be made overstressing at N nodes.
  • a such EG sheath element G exerts an action abrasive, on the one hand, on the external insulation of the conductors C located at the periphery of the beam F, in contact of said EG element, and, on the other hand, on external objects said beam (for example other beams), is finding in contact with said EG sheath element.
  • This action abrasive is all the more important that said beam is subjected to vibrations and that said sheath G occurs in the form of a braid, and that, therefore, its surface is not smooth.
  • the subject of this invention is precisely to remedy the effects of such abrasive action of the protective metal sheath G electromagnetic.
  • the elements of braid ETi are interposed between the conductors C of the beam F and the sheath elements EG of the sheath of electromagnetic shielding G.
  • ETi braid elements form an internal protection Pi and therefore protect the conductors C of the abrasive action of the sheath elements EG.
  • the elements of braid ETe are arranged on the outside of the elements of EG sheath.
  • ETe braid elements provide protection Pe external and therefore protect against action abrasive EG sheath elements, external objects (for example other bundles of conductors) susceptible to be in contact with the external periphery of said elements of EG sheath and vice versa.
  • the embodiment of FIG. 5 comprises, at the same time, ETi braid elements forming internal protection Pi and ETe braid elements forming a protection outdoor Pe.
  • the braid elements ETi and ETe are made up of filaments in a material capable of resisting action abrasive EG sheath elements, such as a material composite, aramid fiber, etc ...
  • the braid elements ETi and ETe are braided directly on the branches of said beam F, for example at by means of a braiding loom.
  • said filaments form strands (twisted or not) or strands (roving) likely to be braided around the branches of said beam.
  • FIGS. 6A to 6E we now describe a example of construction of the braid elements ETi and / or ETe on the beam F, at a node N.
  • the realization braid elements ETi being identical to that of braid elements ETe
  • the braid elements ET1, ET2 and ET3 of FIGS. 6A to 6E represent either elements ETe, either of the elements ETi, depending on the fact that the beam F of FIG. 6A may or may not include EG elements forming a electromagnetic protection sheath G.
  • the beam portion F has branches B1, B2, B3 of unequal sections, the branch B1 having the smallest section and the largest branch B3.
  • the beam F is set up in the loom to braid and the braiding tail Q1 is laid flat on the branch B3.
  • a braid element ET1 which includes a part P1 covering the branch B3 at neighborhood of node N and which completely covers the branch B1.
  • This ET1 braid element is made so that the branch B2 crosses it laterally, at its connection to node N.
  • the braiding parameters (number of braided strands, number of coils distributing the said strands and no braiding) are adjusted so that said element braid ET1 and its part P1 cover, without gaps and without overlays, respectively the entire branch B1 and partially branch B3. Since he is assumed that branch B1 has a cross section smaller than the branch B3, we see that it is necessary that the step of braiding on branch B3 (part P1) is smaller than on branch B1.
  • a braiding tail Q3 which is applied to the braid element ET2 in the vicinity of the node N, and at the following which an ET3 braid element is produced, which includes a part P3 covering the braid element ET2 (branch B2) in the vicinity of said node and which covers fully branch B3.
  • Branch B1 covered with the braid element ET1 and the braiding part P2, crosses the braid element ET3, at its connection at node N.
  • the braiding pitch on branch B2 is larger than on branch B3.
  • the braid element ET3 covers the braiding tail Q1 of braid element ET1 and locks it in position.
  • the braiding tails Q1 and Q3 are themselves locked in position by frets f2, f3 surrounding respectively the branches B1 and B2 and covered with a varnish, preventing them from falling apart under the effect of vibrations.
  • the tail of braiding Q1 is laid flat on branch B3 so that the start of braiding of the P1 part following the queue Q1, instead of going towards node N as shown in Figures 6B to 6D, is made on the contrary over a certain length of the branch B3 moving away from said node, so as to form a first inner layer c1.
  • the sense of advance of the braiding is reversed to get closer to node N (the meaning braiding and its inversion are represented by an arrow t1).
  • Such a hem maintains the braiding tail Q1 in position and allows obtaining a perfect braiding finish.
  • braiding is continued to complete part P1 and realize the element ET1 on the branch B1.
  • the braiding of this element can start at the end of branch B1 opposite node N, instead of starting on branch B3, as previously described. It is therefore advantageous to form a first braiding tail Q'1 which is applied to said branch B1 some distance from this end, to be able to start braiding in the opposite direction said node N, after which we reverse the direction of the advance of the braiding (see arrow t2), to form a hem O blocking said braiding tail Q'1 in position.
  • the braiding of the element ET1 on the branch B1 is continued by direction of node N, then extended on branch B3 to form part P1.
  • a second braiding tail Q "1 is formed and applied to said branch B3. It can be fixed to it by a fret, similar to frets f2 and f3 of Figure 6E (not shown).
  • FIG. 8 The embodiment of Figure 8 is particularly advantageous when a CN connector is fitted at the end of said branch B1 (as shown in the Figure 9) during the production of the element ET1. So, hem O can, by blocking tail Q'1, fix the element ET1 on the EB connector provided on said CN connector for penetrate the branch B1 inside of it. We thus obtains a braiding end capable of resist the constraints imposed on them by frequent handling (connection and disconnection) of said CN connector.
  • Figure 10 illustrates that, on a branch B, we can create an FE window by making two elements of braid AND and AND 'opposite.
  • this figure 10 we have provided that the beginnings of braiding of the elements ET and ET 'included each hem O or O ', as described next to Figures 7, 8 and 9.
  • these beginnings of braiding could consist of simple braiding tails, such as those of FIGS. 6B to 6D.
  • Such a FE window is particularly advantageous when the elements of braid ET and ET 'cover an element EG of metallic sheath G.
  • said FE window makes it possible to leave an update part of said shielding sheath G, which can be connected to a structure serving as a mass, for example the fuselage of a aircraft (helicopter).
  • the harness H shown in Figure 11, represents a case particular of bundle of conductors F, in which the conductors C form a main trunk, starting from nodes from which branches are derived.
  • CN connectors are connected to the free ends of the branches and the embodiment of the braid elements is that of FIGS. 8 and 9, namely beginning of braiding by forming a hem O on the end piece EB of the corresponding connector and braiding stop by braiding tail, preferably blocked by a hoop.
  • the harness H in Figure 11 is protected by progressing from branches of smaller sections towards branches of larger sections, by implementing the particularities of covering the nodes illustrated by Figures 6B to 6D.
  • branch B12 has the same section as branch B21 (i.e. the braiding parameters are the same for said branches B12 and B21)
  • the braid element ET12 which covers the branch B12 and is ends on branch B32 (which corresponds to branch B23 of node N3). This optimizes the braiding time and the use of the braiding loom, following the braid elements having the same braiding parameters.
  • the ET31 braid element is then produced (in the manner of element ET3 of FIG. 6D) by making it begin on branch B21, cover the entire branch B31 (B22) and stop on branch B12.
  • the two branches B15 and B25 are supposed to present the same section. We can then make a short element of braid ET5 starting from B14 (B35) near node N5 and stopping on branch B15, near N5. The branches of identical section B15 and B25 are then covered by a single braid element ET15 (ET25), which starts at the end of the branch B15 and stops at the end of the branch B25.
  • FIG. 12 represents a harness H 'comprising several branches connecting different equipment (not shown) and having variable sections, but not having an axis main serving the different directions.
  • harness H ′ in FIG. 12 can be coated with a braided protection, just like harness H in Figure 11.
  • these braid elements form an excellent top coat for harnesses. They can also serve as an underlay and reinforcement for a waterproofing coating applied to harnesses. Indeed, eventually, said braid elements could be the seat of a wicking effect propagating fluids (water, fuel, hydraulic fluid, ...), likely to come to their contact, which could be dangerous. It is by example particularly so for harnesses arranged at less partially outside the fuselage of an aircraft. Also, it is advantageous to deposit a sealant, for example by means of a spray gun, on said braid elements in order to seal said harness. It will be noted that these braid elements are then used strongly hang the waterproofing coating on the harness and avoid excessive abrasion of said coating.
