Description

outil de liaison électrique garantissant un passage de courant optimum par simple serrage de l’âme d’un fil à relierelectrical connection tool guaranteeing optimum current flow by simply tightening the core of a wire to be connected

La présente invention concerne le domaine de l’outillage électrique industriel.The present invention relates to the field of industrial electrical tools.

L’objet de la présente invention porte plus particulièrement sur un dispositif permettant de créer un liaison électrique fiable, aisément maintenable et compacte pour des niveaux courants forts.The object of the present invention relates more particularly to a device making it possible to create a reliable, easily maintainable and compact electrical connection for high current levels.

Art antérieurPrior art

On connaît pour réaliser une liaison électrique en courant fort plusieurs solutions dans l’art antérieur.Several solutions are known in the prior art for making a high-current electrical connection.

Une première solution illustrée en annexée à la présente description consiste à réaliser la liaison électrique à l’aide d’une cosse 1A sertie sur le fil à relier et maintenue en position par un écrou de serrage 2A sur l’élément conducteur 3A.A first solution illustrated in appended to this description consists of making the electrical connection using a terminal 1A crimped on the wire to be connected and held in position by a tightening nut 2A on the conductive element 3A.

L’un des inconvénients d’une telle solution est que la cosse 1A est sertie sur le fil à relier.One of the disadvantages of such a solution is that terminal 1A is crimped onto the wire to be connected.

Pour sertir cette cosse 1A, il faut utiliser une pince à sertir spécifique pour chaque section de fil disponible.To crimp this 1A terminal, you must use specific crimping pliers for each available wire section.

En cas de remplacement de fil, l’opérateur sur place doit être équiper de cette pince adaptée pour sertir les cosses 1A sur le fil ou avoir des fils à longueur et équipés des cosses serties. Le Demandeur observe que ceci augmente considérablement le nombre de références à tenir en stock pour les opérations de maintenance, ce qui sur le plan pratique n’est pas envisageable.In the event of wire replacement, the operator on site must be equipped with this pliers suitable for crimping the 1A terminals on the wire or have wires to length and equipped with crimped terminals. The Applicant observes that this considerably increases the number of references to be kept in stock for maintenance operations, which on a practical level is not possible.

L’un des autres inconvénients de cette solution est que la cosse 1A possède une longue partie rigide pour permettre de sertir le fil. Cette partie rigide peut être un problème pour réduire l’espace entre deux éléments conducteurs et des potentiels électriques différentsOne of the other disadvantages of this solution is that terminal 1A has a long rigid part to allow the wire to be crimped. This rigid part can be a problem for reducing the space between two conductive elements and different electrical potentials

Une deuxième solution illustrée en annexée à la présente description consiste à réaliser la liaison à l’aide d’un système 2B de serrage axial de l’âme du fil.A second solution illustrated in appended to this description consists of making the connection using a system 2B for axial tightening of the core of the wire.

L’un des inconvénients de ce système est que la liaison entre l’élément conducteur 1B et le fil 3B est obligatoirement coaxiale. Une telle conception soulève des problèmes pour cheminer des fils de grandes sections dans un espace réduit en profondeur car le fil doit respecter un rayon de courbure minimum pour conserver son intégrité.One of the disadvantages of this system is that the connection between the conductive element 1B and the wire 3B is necessarily coaxial. Such a design raises problems for routing wires of large sections in a reduced depth space because the wire must respect a minimum radius of curvature to maintain its integrity.

Le Demandeur observe que les solutions citées ci-dessus permettent de garantir le passage de courants forts en rapport avec la section de l’élément conducteur et celle du fil à relier mais posent des problèmes d’encombrement et/ou de maintenance.The Applicant observes that the solutions cited above make it possible to guarantee the passage of strong currents in relation to the section of the conductive element and that of the wire to be connected but pose problems of bulk and/or maintenance.

Pour ces raisons, le Demandeur soumet que les solutions de l’art antérieur ne sont pas pleinement satisfaisantes car celles-ci ne sont pas adapter à l’environnement existant.For these reasons, the Applicant submits that the solutions of the prior art are not fully satisfactory because they are not adapted to the existing environment.

Objet de l’inventionObject of the invention

La présente invention vise à améliorer la situation décrite ci-dessus.The present invention aims to improve the situation described above.

Un des objectifs de la présente invention est de remédier aux différents inconvénients mentionnés ci-dessus en proposant la conception d’un outil de liaison électrique garantissant un passage de courant optimum par simple serrage de l’âme du fil à relier.One of the objectives of the present invention is to remedy the various drawbacks mentioned above by proposing the design of an electrical connection tool guaranteeing optimum current flow by simply tightening the core of the wire to be connected.

Description détailléedetailed description

Un outil de liaison électrique 10 garantissant un passage de courant optimum par simple serrage de l’âme du fil à relier 10 selon un exemple de réalisation de la présente invention va maintenant être décrit dans ce qui va suivre en référence conjointement aux figures 3 à 6.An electrical connection tool 10 guaranteeing optimum current flow by simply tightening the core of the wire to be connected 10 according to an exemplary embodiment of the present invention will now be described in what follows with reference jointly to Figures 3 to 6 .

Selon le concept sous-jacent à la présente invention, le Demandeur a étudié l’orientation de l’axe de la sortie de fil 10 en suivant deux objectifs :
- diminuer l’encombrement en profondeur ; et
- garder la possibilité d’aligner plusieurs systèmes identiques sans qu’ils ne se gênent l’un l’autre, comme par exemple dans un connecteur à plusieurs voies de puissance.According to the concept underlying the present invention, the Applicant has studied the orientation of the axis of the wire outlet 10 following two objectives:
- reduce bulk in depth; And
- maintain the possibility of aligning several identical systems without them interfering with each other, as for example in a connector with several power channels.

Selon ce concept, il devient possible grâce à cet angle de diminuer de près de moitié l’encombrement en profondeur pour une section de fil et un passage de courant équivalent tout en respectant les préconisations de rayon de courbure minimum des fils utilisés.According to this concept, it becomes possible, thanks to this angle, to reduce the overall depth by almost half for a wire section and an equivalent current flow while respecting the recommendations for the minimum radius of curvature of the wires used.

Comme illustré en , le serrage du fil à relier 10 est assuré par deux simples vis 13 du type ISO 4762. Ce principe permet de limiter l’outillage à des outils standards lors des opérations de montage ou de maintenance sur site. Ce qui représente un gain de temps et d’argent.As illustrated in , the tightening of the wire to be connected 10 is ensured by two simple screws 13 of the ISO 4762 type. This principle makes it possible to limit the tools to standard tools during assembly or maintenance operations on site. Which represents a saving of time and money.

Il est envisagé une gamme adaptée à différentes sections de fil afin de répondre à différentes demandes de courant.A range adapted to different wire sections is envisaged in order to meet different current demands.

Les figures 5 et 6 se réfèrent à un exemple de module d’interconnexion 16x300A (référence 100).Figures 5 and 6 refer to an example of a 16x300A interconnection module (reference 100).

Selon cet exemple, il est prévu sur ce module 100 une interface possédant seize modules contacts femelles capables de laisser passer 300A en continu.According to this example, an interface is provided on this module 100 having sixteen female contact modules capable of passing 300A continuously.

Dans cet exemple, pour passer une telle intensité, chaque contact doit être relié à un fil 12 de 70mm² de section.In this example, to pass such an intensity, each contact must be connected to a wire 12 with a section of 70mm².

Il est observé ici que ce système de liaison électrique a été retenu afin d’optimiser le volume en partie arrière de l’interconnexion.It is observed here that this electrical connection system was retained in order to optimize the volume in the rear part of the interconnection.

Dans cet exemple, et comme illustré en , les supports de contacts sur cette interface sont montés sur une plaque en aluminium à l’aide de douilles d’isolation maintenues par des anneaux élastiques. En partie arrière du support, le fil 12 de 70mm² est positionnée dans un logement dédié. Il est maintenu pas une clame 17 également dédiée pour cette section.In this example, and as illustrated in , the contact supports on this interface are mounted on an aluminum plate using insulation sockets held by snap rings. In the rear part of the support, the 70mm² wire 12 is positioned in a dedicated housing. It is maintained by a clame 17 also dedicated for this section.

Il devra être observé que cette description détaillée porte sur plusieurs exemples de réalisation particuliers de la présente invention, mais qu’en aucun cas cette description ne revêt un quelconque caractère limitatif à l’objet de l’invention ; bien au contraire, elle a pour objectif d’ôter toute éventuelle imprécision ou toute mauvaise interprétation des revendications qui suivent.It should be observed that this detailed description relates to several particular embodiments of the present invention, but that in no case does this description have any limiting character to the subject of the invention; on the contrary, it aims to remove any possible imprecision or misinterpretation of the claims that follow.
