Abstract

The invention relates to a welded assembly in an area (2) for welding a cable (1) including several yarns made of a first metal and a holder (3) made of a second metal different from the first metal, one of the two metals consisting of copper, aluminium or an alloy thereof.

Description

La présente invention se rapporte aux assemblages soudés d'un câble à plusieurs brins en un premier métal et d'un support en un deuxième métal différent du premier. L'un des deux métaux est notamment du cuivre, de l'aluminium ou l'un de leurs alliages.The present invention relates to welded joints of a multi-strand cable made of a first metal and a support made of a second metal different from the first. One of the two metals is in particular copper, aluminum or one of their alloys.

On connaît déjà par exemple de US 2006/0292922 le fait d'assembler un câble et un support par sertissage du support autour du câble. Le support y entoure complètement les brins du câble. Il n'est pas prévu de les assembler par soudure, ce qui d'ailleurs, compte tenu de l'entourage complet par le support n'est pas possible.For example, we already know US 2006/0292922 assembling a cable and a support by crimping the support around the cable. The support completely surrounds the strands of the cable. It is not planned to assemble them by welding, which moreover, considering the complete entourage by the support is not possible.

Il est déjà connu par exemple de FR 2888661 d'assembler un câble de cuivre à un barreau d'aluminium par soudure par friction, par ultrasons ou autres. Mais on constate que la soudure se détruit rapidement.It is already known for example from FR 2888661 to assemble a copper cable to an aluminum bar by friction welding, ultrasound or other. But we find that the weld is destroyed quickly.

L'invention pallie cet inconvénient par un assemblage suivant la revendication 1, des perfectionnements étant définis aux sous revendications.The invention overcomes this disadvantage by an assembly according to claim 1, improvements being defined in the subclaims.

En remplissant les interstices entre les brins et/ou entre les brins et le support d'une matière inerte, on améliore la résistance à long terme de la soudure entre les brins et le support. En effet, on empêche qu'ait lieue une réaction électrochimique entre le matériau constituant le ou les brins et le matériau du support en disposant entre eux un matériau dont le potentiel électrochimique par rapport aux potentiels électrochimiques des deux matériaux est tel qu'il ne peut pas y avoir de corrosion qui se développe ou que seule une corrosion infime se développe. Ainsi la corrosion n'attaque pas entre les brins et il s'avère que lutter contre la corrosion au niveau des interstices a pour effet de faire en sorte que la soudure tienne bien au niveau du contact entre les brins et le support.By filling the interstices between the strands and / or between the strands and the support of an inert material, the long-term strength of the weld between the strands and the support is improved. Indeed, it prevents an electrochemical reaction between the material constituting the one or more strands and the material of the support by placing between them a material whose electrochemical potential with respect to the electrochemical potentials of the two materials is such that it can not there is no corrosion that develops or only a small corrosion develops. Thus corrosion does not attack between the strands and it turns out that fight against corrosion at the interstices has the effect of ensuring that the weld is well at the contact between the strands and the support.

De préférence, la matière inerte a une viscosité faible, par exemple inférieure à 500 mPa.s, notamment inférieure à 100 mPa.s.Preferably, the inert material has a low viscosity, for example less than 500 mPa.s, especially less than 100 mPa.s.

Ainsi, lors de la soudure, la matière emplit rapidement les interstices avant de durcir, de sorte que de l'air, favorable à la corrosion ne peut pas rester dans ces interstices.Thus, during welding, the material quickly fills the gaps before curing, so that air, favorable to corrosion can not remain in these interstices.

De préférence, la matière inerte est l'étain.Preferably, the inert material is tin.

Ainsi, les brins sont bien protégés par l'étain apporté qui s'est répandu par capillarité entre les brins. La protection est meilleure que dans le cas d'une simple étanchéité extérieure. La circulation des ions en présence d'humidité est empêchée.Thus, the strands are well protected by the tin brought which has spread by capillarity between the strands. The protection is better than in the case of a simple external seal. The circulation of ions in the presence of moisture is prevented.

De préférence, la soudure est une soudure sans apport de matière, c'est-à-dire qu'il ne s'agit pas d'une brasure. En particulier la soudure est à ultrason ou à friction.Preferably, the weld is a weld without adding material, that is to say it is not a solder. In particular the welding is ultrasonic or friction.

On a maintenant compris que la destruction de la soudure provient du potentiel électrochimique différent entre les deux métaux. En présence d'humidité, il se produit une oxydation rapide qui entraîne la destruction de la soudure. Suivant l'invention, on évite cette réaction en empêchant l'humidité d'arriver dans les zones soudées. Il ne suffit pas à cet effet de rendre étanche les zones de soudure car l'humidité peut remonter entre les brins du câble en le premier métal, notamment en cuivre. En revanche le remplissage des interstices suivant l'invention réalise à la fois l'étanchéité extérieure de la soudure et un barrage à la remontée d'humidité entre les brins, ce qui met la soudure bien à l'abri de toute réaction chimique.It has now been understood that the destruction of the weld results from the different electrochemical potential between the two metals. In the presence of moisture, rapid oxidation occurs which leads to the destruction of the weld. According to the invention, this reaction is avoided by preventing moisture from reaching the welded areas. It is not sufficient for this purpose to seal the weld areas because moisture can rise between the strands of the cable made of the first metal, in particular copper. On the other hand, the filling of the interstices according to the invention achieves both the external sealing of the weld and a barrier to the rise of moisture between the strands, which puts the weld well away from any chemical reaction.

De préférence, la matière inerte est introduite de telle manière que celle-ci dépasse de la zone de soudure.Preferably, the inert material is introduced in such a way that it protrudes from the weld zone.

En général, le câble est en le premier métal, notamment en cuivre et le support est en le deuxième métal notamment en aluminium.In general, the cable is made of the first metal, in particular copper and the support is made of the second metal, in particular aluminum.

Cette protection peut être complétée par un manchon rétractable, notamment.en matière plastique, ou un vernis ou autre revêtement isolant.This protection may be supplemented by a retractable sleeve, in particular.a plastic material, or a varnish or other insulating coating.

On effectue le remplissage ou l'étamage à la manière habituelle en recouvrant la zone de soudure d'un flux désoxydant, puis en faisant fondre l'étain sur et dans les parties souhaitées.The filling or tinning is carried out in the usual manner by covering the solder area with a deoxidizing stream, and then melting the tin on and in the desired parts.

Lorsque les soudures concernent des câbles et barreaux de grande section, on élève l'ensemble rapidement en température par exemple par réchauffement par induction, par résistance électrique ou au chalumeau ou bien par étamage à la vague ou sous un flux d'air chaud supérieur à 230°C.When the welds concern cables and bars of large section, the assembly is raised rapidly in temperature for example by induction heating, electrical resistance or torch or by tinning to the wave or under a hot air flow greater than 230 ° C.

Au dessin annexé, donnés uniquement à titre d'exemple :

  • la figure 1 est une vue en plan d'un assemblage soudé avant étamage, tandis que
  • les figures 2 et 3 représentent le même assemblage après étamage, et
  • la figure 4 est une vue en coupe transversale suivant la ligne A-A de la figure 3.
In the annexed drawing, given only by way of example:
  • the figure 1 is a plan view of a welded assembly before tinning, while
  • the Figures 2 and 3 represent the same assembly after tinning, and
  • the figure 4 is a cross-sectional view along line AA of the figure 3 .

L'assemblage soudé représenté à la figure 1, comprend un câble 1 à plusieurs brins 6 en cuivre, dont une zone de soudure est soudée à une zone de soudure d'un support 3 constitué d'un barreau d'aluminium, la soudure des deux zones s'effectuant à un interface 2.The welded assembly shown in figure 1 , comprises a multi-strand cable 1 made of copper, a soldering zone of which is welded to a welding zone of a support 3 consisting of an aluminum bar, the welding of the two zones being effected at an interface 2 .

La figure 3 montre que les zones de soudure formant l'interface 2 ainsi qu'une zone 4 du câble voisine de la zone de soudure sont revêtues d'une couche 5 d'étain.The figure 3 shows that the welding zones forming the interface 2 and a zone 4 of the cable close to the weld zone are coated with a layer of tin.

La zone 4 a une longueur, décomptée suivant la direction longitudinale du câble 1, supérieure à 0,1 mm.Zone 4 has a length, counted in the longitudinal direction of the cable 1, greater than 0.1 mm.

La partie du câble 1 se trouvant au-dessus (tel que vu aux figures) de l'interface 2 et la partie du barreau 3 se trouvant en dessous de l'interface 2 sont entièrement recouvertes de la couche d'étain. En outre, cette couche d'étain recouvre une partie 4 supplémentaire du câble et une partie supplémentaire du barreau. On pourrait également prévoir de ne recouvrir de la couche d'étain que la partie du câble 1 se trouvant au-dessus de l'interface 2 et pas la partie du barreau 3 en dessous de l'interface 2. De même la couche d'étain pourrait ne recouvrir que la partie 4 supplémentaire du câble et pas de partie supplémentaire du barreau.The portion of the cable 1 located above (as seen in the figures) of the interface 2 and the portion of the bar 3 located below the interface 2 are completely covered with the tin layer. In addition, this layer of tin covers an additional portion 4 of the cable and an additional portion of the bar. It could also be provided to cover the tin layer only the portion of the cable 1 located above the interface 2 and not the portion of the bar 3 below the interface 2. Also the layer of tin could cover only the additional part 4 of the cable and no additional part of the bar.

Tous les brins de cuivre sont recouverts d'étain. Il n'y a pas de circulation électrique possible du cuivre vers l'aluminium, et ce même si l'aluminium n'est pas recouvert.All strands of copper are covered with tin. There is no possible electrical circulation of copper to aluminum, even if the aluminum is not covered.

Comme on le voit bien à la figure 4, les interstices 7 entre les brins 6 du câble 1 et les interstices 8 entre les brins du câble et le support sont emplis d'une matière inerte d'un point de vue de la corrosion vis-à-vis des deux métaux du câble et du support 3, c'est-à-dire que le potentiel électrochimique de la matière inerte (ici l'étain) par rapport à celui de chacun des métaux est tel que la corrosion ne peut avoir lieu ou est infime.As can be seen from the figure 4 , the interstices 7 between the strands 6 of the cable 1 and the gaps 8 between the strands of the cable and the support are filled with a material which is inert from the point of view of corrosion with respect to the two metals of the cable and of the support 3, that is to say that the electrochemical potential of the inert material (here tin) relative to that of each of the metals is such that corrosion can not take place or is minute.

On peut également prévoir comme matière inerte, une résine dite anaérobie.It is also possible to provide as an inert material, an anaerobic resin.

Après soudure par ultrasons des deux parties métalliques (les brins du câble et le support), on apporte la matière inerte par soudure (étamage classique) dans le cas d'un troisième métal tel que l'étain, l'étain liquide pénétrant ainsi entre les interstices puis se solidifiant après refroidissement. Dans le cas d'une résine anaérobie, on introduit à température la résine liquide qui s'écoule dans les interstices et on la laisse prendre en masse pour ainsi être fixée.After ultrasonic welding of the two metal parts (the strands of the cable and the support), the inert material is soldered (conventional tinning) in the case of a third metal such as tin, the liquid tin thus penetrating between the interstices then solidifying after cooling. In the case of an anaerobic resin, the liquid resin which flows in the interstices is introduced at temperature and allowed to set in bulk so as to be fixed.

Aucun air ne subsiste dans les interstices qui sont complètement rempli de la matière inerte.No air remains in the interstices that are completely filled with the inert matter.

De préférence, la matière inerte métallique, telle que l'étain, a une viscosité à la température de soudure qui est inférieure ou égale à 100 mPa.s.Preferably, the metallic inert material, such as tin, has a viscosity at the solder temperature of less than or equal to 100 mPa.s.

De préférence, la matière inerte anaérobie a une viscosité à la température ambiante qui est inférieure ou égale à 500 mPa.s.Preferably, the anaerobic inert material has a viscosity at room temperature that is less than or equal to 500 mPa.s.

En particulier, la résine anaérobie peut être de la LOCTITE (résine acrylique ex:mathacrylate monomère).In particular, the anaerobic resin may be LOCTITE (acrylic resin, eg monomeric mathacrylate).

Comme on le voit bien aux figures, des brins (les brins de base à la figure) sont en contact avec le support suivant une ligne droite correspondant à la surface plane et plate du support. Le support n'entoure pas le câble. Seule les brins de la rangée inférieure sont en contact de soudure avec le support. Malgré cela, la fixation par soudure des deux éléments (câble et support) a une longue durée de vie.As can be seen in the figures, strands (the base strands in the figure) are in contact with the support in a straight line corresponding to the flat and flat surface of the support. The stand does not surround the cable. Only the strands of the lower row are in solder contact with the support. In spite of this, the attachment by welding of the two elements (cable and support) has a long life.
