Description

L'invention concerne un fil électrique comportant une âme en aluminium ou alliage d'aluminium.The invention relates to an electric wire comprising a core of aluminum or aluminum alloy.

Lors de sertissage d'un fil en aluminium ou alliage d'aluminium dans un manchon de sertissage, compte-tenu de la différence des coefficients de dilatation thermique de l'aluminium et du métal constituant le manchon de sertissage, souvent en alliage de cuivre, il se produit des formations d'alumine autour du fil par oxydation à l'air. Or, l'alumine est électriquement résistant et entraîne en conséquence une augmentation de la résistance électrique de contact, qui peut créer une rupture du contact, dans le cas de faibles courants, ou un échauffement , dans le cas de forts courants.When crimping an aluminum or aluminum alloy wire in a crimping sleeve, taking into account the difference in the thermal expansion coefficients of aluminum and the metal constituting the crimping sleeve, often made of copper alloy, alumina formation occurs around the wire by oxidation in the air. However, alumina is electrically resistant and consequently leads to an increase in the electrical contact resistance, which can create a break in the contact, in the case of low currents, or heating in the case of strong currents.

Le but de l'invention est d'éviter cette formation d'une couche d'alumine autour du fil électrique, par revêtement du fil par un matériau qui ne présente pas ces propriétés isolantes préjudiciables au bon fonctionnement électrique du conducteur.The object of the invention is to avoid this formation of a layer of alumina around the electrical wire, by coating the wire with a material that does not have these insulating properties detrimental to the proper electrical operation of the conductor.

Il est proposé dans le document de brevet US 3 636 242 un fil électrique avec une âme en aluminium ou alliage d'aluminium pourvue d'une couche de revêtement en alliage de zinc et de nickel, le taux en poids de nickel dans cet alliage étant compris entre 25 et 75%.US Pat. No. 3,636,242 proposes an electrical wire with an aluminum or aluminum alloy core provided with a coating layer of zinc and nickel alloy, the weight ratio of nickel in this alloy being between 25 and 75%.

Cet agencement présente les problèmes techniques suivants.This arrangement presents the following technical problems.

Le zinc est plus électronégatif que l'aluminium et joue un rôle sacrificiel en cas de corrosion galvanique. Une proportion élevée de nickel allié au zinc diminue cette propriété de protection.Zinc is more electronegative than aluminum and plays a sacrificial role in the event of galvanic corrosion. A high proportion of nickel zinc alloy decreases this protective property.

Par ailleurs, le coût du zinc est très inférieur au coût du nickel et un tel agencement est donc coûteux proportionnellement au taux de nickel utilisé.Moreover, the cost of zinc is much lower than the cost of nickel and such an arrangement is therefore expensive in proportion to the nickel rate used.

Enfin le codépot de nickel avec le zinc permet d'améliorer la tenue à la corrosion par rapport à un dépôt de zinc pur.Finally, the nickel codépot with zinc makes it possible to improve the resistance to corrosion compared to a deposit of pure zinc.

L'invention permet de trouver un compromis entre ces différentes données que sont la résistance à la corrosion, y compris la corrosion galvanique, et le coût d'un fil à âme en aluminium ou alliage en aluminium.The invention makes it possible to find a compromise between these various data, namely the corrosion resistance, including galvanic corrosion, and the cost of a core wire made of aluminum or aluminum alloy.

Pour ce faire, l'invention propose un fil électrique comportant une âme en aluminium ou alliage d'aluminium pourvue d'une couche de revêtement en alliage de zinc et de nickel, caractérisé en ce que le taux en poids du nickel dans cet alliage est compris entre 5% et 15%, en négligeant les impuretés courantes.To do this, the invention proposes an electrical wire comprising an aluminum or aluminum alloy core provided with a zinc alloy and nickel coating layer, characterized in that the weight ratio of nickel in this alloy is between 5% and 15%, neglecting common impurities.

Selon un mode de réalsiation préféré, ledit alliage de zinc et de nickel est un codépôt sur ladite âme, c'est-à-dire que le zinc et le nickel sont alliés lors de leur dépôt sur l'âme en aluminium ou alliage d'aluminium.According to a preferred embodiment, said zinc and nickel alloy is a codeposit on said core, that is to say that zinc and nickel are alloyed during their deposition on the aluminum or alloy core. aluminum.

De préférence, l'épaisseur de ladite couche de revêtement est comprise entre 0,1 µm et 10 µm sur le fil fini.Preferably, the thickness of said coating layer is between 0.1 μm and 10 μm on the finished wire.

Avantageusement, ladite couche de revêtement est déposée sur le conducteur par électrodéposition.Advantageously, said coating layer is deposited on the conductor by electroplating.

Eventuellement, ladite couche de revêtement est passivée, par exemple par du chrome, du molybdate ou du phosphate pour augmenter la tenue à la corrosion.Optionally, said coating layer is passivated, for example by chromium, molybdate or phosphate to increase the resistance to corrosion.

L'invention concerne également un conducteur électrique monobrin réalisé par un fil tel que précisé ci-dessus.The invention also relates to a single strand electrical conductor made by a wire as specified above.

L'invention concerne enfin un conducteur électrique multibrin réalisé par assemblage d'une pluralité de fils tels que précisés ci-dessus.The invention finally relates to a multi-stranded electrical conductor made by assembling a plurality of wires as specified above.

L'invention est décrite ci-après plus en détail à l'aide de figures ne représentant qu'un mode de réalisation préféré de l'invention.The invention is described below in more detail with the aid of figures representing only a preferred embodiment of the invention.

Selon l'invention, le taux en poids de nickel dans cet alliage est compris entre 5% et 15%. L'épaisseur de la couche de revêtement 3 est comprise entre 0,1 µm et 10 µm.According to the invention, the weight ratio of nickel in this alloy is between 5% and 15%. The thickness of the coating layer 3 is between 0.1 μm and 10 μm.

Afin d'augmenter encore plus la passivation de cet alliage à l'oxydation, cet alliage peut également être traité par chromatation, par du molybdate, par du phosphate ou équivalent. Ce traitement peut être réalisé par trempe du fil revêtu.In order to further increase the passivation of this alloy to oxidation, this alloy may also be treated by chromating, molybdate, phosphate or the like. This treatment can be performed by quenching the coated wire.

Un fil électrique conforme à l'invention est fabriqué par tréfilage. La couche de revêtement 3 est disposée par électrodéposition sur une âme à un état intermédiaire puis l'ensemble de l'âme et de la couche de revêtement est tréfilée au diamètre final.An electric wire according to the invention is manufactured by wire drawing. The coating layer 3 is electrodeposited on a core to an intermediate state and then the entire core and the coating layer is drawn to the final diameter.
