Description
La présente invention concerne les cosses de connexion de câbles en aluminium ou autre métal conducteur et concerne en particulier un dispositif et un procédé de réparation des cosses de connexion électrique.The present invention relates to lugs for connecting cables of aluminum or other conductive metal and particularly relates to a device and a method for repairing the electrical connection lugs.
Aujourd'hui, les cosses qui permettent la connexion de câbles métalliques serties se dégradent à cause de 1'oxydation du métal. Ainsi, la plupart des câbles de connexion électrique sont en aluminium et, au cours du temps, il se produit une couche d'alumine autour de brins constituant le câble. En conséquence, la résistance de la connexion augmente avec le temps et entraîne une dégradation des performances et, en particulier, une consommation électrique accrue, mais entraîne également un échauffement anormal qui peut conduire à un emballement thermique. C'est pourquoi le but de l'invention est de fournir un dispositif et un procédé de réparation des cosses de connexion électrique permettant d'augmenter la conductance de la cosse réparée.Today, the lugs that allow the connection of crimped metal cables degrade due to the oxidation of the metal. Thus, most electrical connection cables are aluminum and, over time, there is a layer of alumina around strands constituting the cable. As a result, the resistance of the connection increases with time and leads to a degradation of performance and, in particular, increased power consumption, but also leads to abnormal heating which can lead to thermal runaway. This is why the object of the invention is to provide a device and a method for repairing the electrical connection lugs making it possible to increase the conductance of the repaired lug.
Un premier objet de 1'invention est donc un dispositif de réparation d'une cosse de connexion électrique comprenant un manchon métallique solidaire d'une plage de connexion, la cosse étant rendue solidaire d'un câble métallique par sertissage, poinçonnage, serrage mécanique ou rétreint hexagonal. Le dispositif comprend un insert métallique à expansion tel qu'un cône enfoncé dans un trou traversant le manchon et le câble, ledit insert métallique étant entouré d'un élément composé d'une feuille de mousse métallique constituée d'un squelette de mousse de métal à cellules ouvertes choisi dans le groupe consistant en fer, cobalt, nickel et leurs alliages recouvert directement d'au moins un revêtement de cuivre, d'étain, d'indium ou un de leurs alliages.A first object of the invention is therefore a device for repairing an electrical connection lug comprising a metal sleeve integral with a connection pad, the lug being secured to a wire rope by crimping, punching, mechanical clamping, or hexagonal necking. The device comprises an expanding metal insert such as a cone embedded in a hole through the sleeve and the cable, said metal insert being surrounded by an element made of a metal foam sheet consisting of a skeleton of metal foam open cell selected from the group consisting of iron, cobalt, nickel and their alloys directly coated with at least one coating of copper, tin, indium or an alloy thereof.
Un second objet de l'invention est un procédé de réparation d'une cosse de connexion électrique comprenant un manchon métallique solidaire d'une plage de connexion, la cosse étant rendue solidaire d'un câble métallique par sertissage, poinçonnage, serrage mécanique ou rétreint hexagonal le procédé consistant à enfoncer un insert métallique à expansion dans un trou traversant le manchon et le câble, ledit insert à expansion étant entouré d'un élément composé d'une feuille de mousse métallique constituée d'un squelette de mousse de métal à cellules ouvertes choisi dans le groupe consistant en fer, cobalt, nickel et leurs alliages recouvert directement d'au moins un revêtement de cuivre, d'étain, d'indium ou un de leurs alliages. D'autres buts, objets et caractéristiques de l'invention apparaîtront plus clairement à la lecture de la description qui suit faite en référence aux dessins dans lesquels : la figure 1 représente une cosse de connexion électrique avant sa réparation; la figure 2 représente schématiquement le dispositif selon l'invention avant sa mise en place dans une cosse de connexion électrique devant être réparée ; la figure 3 représente une vue en coupe de la cosse à réparer après 1'installation du dispositif selon 1'invention ; et la figure 4 représente une vue en coupe de la cosse après que le dispositif selon 1'invention a été rendu complètement solidaire de la cosse réparée.A second object of the invention is a method of repairing an electrical connection lug comprising a metal sleeve integral with a connection pad, the lug being secured to a wire rope by crimping, punching, mechanical clamping or necking. hexagonal method of driving a metal expansion insert into a hole through the sleeve and the cable, said expansion insert being surrounded by a member made of a metal foam sheet consisting of a skeleton of cellular metal foam open members selected from the group consisting of iron, cobalt, nickel and their alloys directly coated with at least one coating of copper, tin, indium or an alloy thereof. Other objects, objects and features of the invention will appear more clearly on reading the following description made with reference to the drawings in which: FIG. 1 represents an electrical connection lug before its repair; Figure 2 shows schematically the device according to the invention before its introduction into an electrical connection lug to be repaired; Figure 3 shows a sectional view of the lug to be repaired after installation of the device according to the invention; and Figure 4 shows a sectional view of the terminal after the device according to the invention has been made completely integral with the repaired terminal.
La cosse qui fait 1'obj et de 1'invention représentée sur la figure 1 comprend un manchon 10 en métal tel que de 1'aluminium solidaire d'une plage de connexion 12 et est utilisée pour la connexion d'un câble 14 composé d'une pluralité de brins en aluminium.The pod which forms the object of the invention shown in FIG. 1 comprises a metal sleeve 10 such as aluminum secured to a connection pad 12 and is used for connecting a cable 14 consisting of a plurality of aluminum strands.
Lorsque le manchon 10 a été installé autour du câble, on vient le fixer, par sertissage, poinçonnage, serrage mécanique ou rétreint hexagonal au moyen d'un outil adéquat. Si la fixation est par sertissage, elle est réalisée à deux endroits, ce qui provoque deux cavités 16 et 18.When the sleeve 10 has been installed around the cable, it is fixed, by crimping, punching, mechanical clamping or hexagonal necking by means of a suitable tool. If the attachment is crimping, it is performed in two places, which causes two cavities 16 and 18.
Dans le mode de réalisation préférentiel, le procédé de l'invention est mis en œuvre en perçant un trou conique 20 traversant le manchon et le câble dans 1'une des cavités utilisées pour le sertissage, ici la cavité 16, au moyen d'un poinçon. A noter que le percement du trou conique pourrait être réalisé en n'importe quelle partie de la cosse en dehors des cavités 16 et 18.In the preferred embodiment, the method of the invention is implemented by drilling a conical hole 20 passing through the sleeve and the cable into one of the cavities used for crimping, here the cavity 16, by means of a punch. Note that the drilling of the conical hole could be made in any part of the pod outside the cavities 16 and 18.
Puis, comme le montre la figure 2, un insert à expansion, ici un cône métallique 22 en aluminium de préférence, est inséré en force dans le trou conique 20. Avant de placer le cône 22 dans le trou conique 20, une caractéristique essentielle de 1'invention consiste à insérer un élément conique 24 sous la forme d'une feuille de mousse métallique d'une épaisseur d'environ 1,5mm dans le trou conique 2 0. Cet élément conique 2 4 a pour but de diminuer la résistance électrique de la cosse. A noter que 1' élément conique 24 pourrait être placé autour du cône métallique 22 avant son insertion.Then, as shown in FIG. 2, an expansion insert, here a metal cone 22 preferably made of aluminum, is forcefully inserted into the conical hole 20. Before placing the cone 22 in the conical hole 20, an essential characteristic of The invention consists in inserting a conical element 24 in the form of a sheet of metal foam having a thickness of about 1.5 mm in the conical hole 20. This conical element 24 aims to reduce the electrical resistance of the pod. Note that the conical element 24 could be placed around the metal cone 22 before insertion.
La feuille en mousse métallique qui constitue 1'élément conique 24 est constituée d'un squelette de mousse de métal à cellules ouvertes choisi dans le groupe consistant en fer, cobalt, nickel et leurs alliages recouvert directement d'au moins un revêtement de cuivre, d'étain, d'indium ou un de leurs alliages. A noter que le revêtement, par exemple un revêtement de cuivre ou un de ses alliages, peut être lui-même recouvert d'un revêtement d'étain, d'indium ou un de leurs alliages. La mousse métallique ci-dessus fait l'objet du brevet français 10/02988 publié sous le N° 2.962.856 et de la demande internationale de brevet PCT W02012/007701 ; la mousse étant commercialisée sous la marque ECOCONTACT.The foamed metal sheet constituting the conical element 24 consists of an open cell metal foam skeleton selected from the group consisting of iron, cobalt, nickel and their alloys directly coated with at least one copper coating, tin, indium or one of their alloys. Note that the coating, for example a copper coating or one of its alloys, may itself be covered with a coating of tin, indium or an alloy thereof. The above metal foam is the subject of French patent 10/02988 published under No. 2.962.856 and international patent application PCT WO2012 / 007701; the foam being marketed under the trademark ECOCONTACT.
La mousse métallique de 1'élément conique 24 est constituée en maj eure partie de vide du fait de sa structure alvéolaire. De ce fait, la surface de la mousse comporte une multitude de pointes de contact de 1'ordre du micron dont le nombre atteint 30 pointes par millimètre. Grâce à ces pointes, 1' élément conique 24 possède de nombreux contacts, ce qui procure une grande conductivité à la connexion et donc une résistance faible.The metal foam of the conical element 24 consists of a large part of vacuum because of its honeycomb structure. As a result, the surface of the foam has a multitude of micron-sized contact tips whose number reaches 30 points per millimeter. With these tips, the conical element 24 has many contacts, which provides a high conductivity at the connection and therefore a low resistance.
Lorsque le cône métallique 22 est enfoncé en force dans le trou conique 20, l'élément conique 24 est écrasé et l'épaisseur de la feuille de mousse est réduite à environ 2 à 3/10 de millimètre.When the metal cone 22 is forced into the conical hole 20, the conical element 24 is crushed and the thickness of the foam sheet is reduced to about 2 to 3/10 of a millimeter.
Le cône métallique comprend un élément cylindrique 26 dans sa partie supérieure et un élément cylindrique 28 dans sa partie inférieure.The metal cone comprises a cylindrical element 26 in its upper part and a cylindrical element 28 in its lower part.
Comme le montre la figure 3, l'élément cylindrique 26 dépasse le manchon de la cosse. Lorsque le cône métallique 22 est enfoncé en force dans le trou conique 20, par exemple au moyen d'une presse hydraulique, seul l'élément cylindrique 26 peut être déformé ce qui évite une éventuelle déformation du cône métallique 22.As shown in Figure 3, the cylindrical member 26 protrudes from the sleeve of the pod. When the metal cone 22 is forced into the conical hole 20, for example by means of a hydraulic press, only the cylindrical element 26 can be deformed, thereby avoiding any deformation of the metal cone 22.
De même, l'élément cylindrique 28 dépasse du manchon dans sa partie basse comme le montre la figure 3. Lorsque le cône 22 a été placé, la dernière étape du procédé consiste à élargir la partie de 1'élément cylindrique 28 qui dépasse de manière à constituer un rivet 30 comme illustré sur la figure 4. Ainsi, le cône métallique 22 entouré de l'élément 24 en mousse métallique est rendu complètement solidaire de la cosse à réparer. A noter que la mousse métallique de grande conductivité qui entoure le cône métallique 22, procure une liaison électrique de moindre résistance entre le câble 14 et le manchon 10 grâce à ses contacts en partie haute et en partie basse avec le manchon.Likewise, the cylindrical element 28 protrudes from the sleeve in its lower part as shown in FIG. 3. When the cone 22 has been placed, the last step of the method consists in widening the part of the cylindrical element 28 which protrudes to form a rivet 30 as illustrated in Figure 4. Thus, the metal cone 22 surrounded by the element 24 of metal foam is made completely integral with the pod to be repaired. Note that the high conductivity metal foam surrounding the metal cone 22, provides an electrical connection of lesser resistance between the cable 14 and the sleeve 10 through its contacts in the upper part and in the lower part with the sleeve.
Des exemples de réalisation de l'invention décrite ci-dessus ont montré que la résistance de la cosse était réduite de 80 à 90% de la résistance avant l'installation du dispositif.Exemplary embodiments of the invention described above have shown that the resistance of the terminal was reduced by 80 to 90% of the resistance before the installation of the device.
Bien que, dans le mode de réalisation préférentiel, un cône métallique soit utilisé comme insert à expansion, il pourrait être remplacé par tout autre insert à expansion tel qu'un cylindre à expansion. A noter que, bien que le dispositif selon 1'invention est principalement utilisé pour réparer les cosses anciennes dans lesquelles les brins du câble ont été oxydés, par exemple se sont couverts d'une couche d'alumine s'il s'agit d'un câble en aluminium, il pourrai être utilisé dans la fabrication des nouvelles cosses de façon à se prémunir contre leur dégradation.Although, in the preferred embodiment, a metal cone is used as an expansion insert, it could be replaced by any other expansion insert such as an expansion cylinder. Note that, although the device according to the invention is mainly used to repair the old pods in which the strands of the cable have been oxidized, for example have covered with a layer of alumina if it is an aluminum cable, it can be used in the manufacture of new lugs so as to guard against their degradation.
