DISPOSITIF DE CONTACT ELECTRIQUE DE TYPE DOIGT DE CONTACT A FORT COURANT NOMINAL  ELECTRIC CONTACT DEVICE OF CONTACT TYPE WITH STRONG CURRENT CURRENT
DESCRIPTION DESCRIPTION
DOMAINE TECHNIQUE TECHNICAL AREA
L'invention concerne un dispositif de contact électrique de type doigt de contact à fort courant nominal The invention relates to a contact contact type electric contact device with a high current rating
ÉTAT DE LA TECHNIQUE ANTÉRIEURE STATE OF THE PRIOR ART
Un premier exemple connu de réalisation d'un contact électrique de type doigt de contact entre une première pièce 10 et une seconde pièce 11 est illustré sur la figure 1. Le contact électrique est réalisé par un plot de contact 12 appliqué sur une surface conductrice de la seconde pièce 11 suivant une zone de contact 13, des lames métalliques 14 et une tige flexible 15. Ces lames qui sont reliées à un élément 16 de jonction mécanique et électrique à la première pièce 10 assurent le passage du courant entre le plot de contact 12 et cet élément 16. La tige flexible 15 assure une fonction ressort et permet de réaliser l'effort de contact sans assurer de passage de courant électrique. A first known example of embodiment of a contact finger type electrical contact between a first part 10 and a second part 11 is illustrated in FIG. 1. The electrical contact is made by a contact pad 12 applied to a conducting surface of the second part 11 following a contact zone 13, metal blades 14 and a flexible rod 15. These blades which are connected to a mechanical and electrical connection element 16 to the first part 10 ensure the passage of current between the contact pad 12 and this element 16. The flexible rod 15 provides a spring function and makes it possible to achieve the contact force without ensuring the passage of electric current.
Un second exemple connu de réalisation d'un contact électrique de type doigt de contact consiste en un contact monobloc dont les trois fonctions de contact électrique, de passage de courant électrique et de ressort décrites ci-dessus sont réalisées en un seul élément obtenu par exemple par usinage ou par matriçage . A second known example of producing a contact-type electrical contact consists of a monoblock contact whose three functions of electrical contact, electrical current flow and spring described above are made in one element obtained for example by machining or stamping.
Ce second exemple constitue un mode de réalisation économique. Toutefois, une difficulté subsiste du fait du dimensionnement conjoint de la fonction passage de courant et de la fonction ressort. La fonction passage de courant implique un choix de matériaux ayant des propriétés conductrices satisfaisantes pour limiter les échauffements : typiquement du cuivre, de l'aluminium ou leurs alliages. Mais l'utilisation de tels matériaux pour assurer la fonction ressort entraîne des limites importantes concernant les dimensions de contact, notamment du fait des contraintes et de l'effort résultant, en particulier en raison d'une contrainte maximum à ne pas dépasser dans le matériau. Il en résulte que pour un encombrement donné, ce second exemple présente une valeur limite de courant nominal admissible .  This second example constitutes an economic embodiment. However, a difficulty remains because of the joint dimensioning of the current flow function and the spring function. The current flow function involves a choice of materials having satisfactory conductive properties to limit heating: typically copper, aluminum or their alloys. But the use of such materials to ensure the spring function causes significant limits on the contact dimensions, especially because of the constraints and the resulting effort, in particular because of a maximum stress not to be exceeded in the material . It follows that for a given size, this second example has a limit value of nominal current.
L'invention a pour objet de modifier un tel contact monobloc, ou de conception proche d'un tel contact monobloc, pour augmenter le courant nominal dans un encombrement donné.  The invention aims to modify such a monobloc contact, or design close to such a monobloc contact, to increase the nominal current in a given space.

BRÈVE DESCRIPTION DES DESSINS BRIEF DESCRIPTION OF THE DRAWINGS
La figure 1 illustre un exemple de dispositif de contact de l'art connu. FIG. 1 illustrates an exemplary contact device of the known art.
Les figures 2 et 3 illustrent deux modes de réalisation du dispositif de l'invention. Les figures 4 à 6 illustrent des caractéristiques du dispositif de l'invention tel qu'illustré sur les figures 2 et 3. EXPOSÉ DÉTAILLÉ DE MODES DE RÉALISATION PARTICULIERS Figures 2 and 3 illustrate two embodiments of the device of the invention. Figures 4 to 6 illustrate features of the device of the invention as illustrated in Figures 2 and 3. DETAILED DESCRIPTION OF PARTICULAR EMBODIMENTS
Dans le dispositif de l'invention, comme illustré sur les figures 2 et 3, un élément de contact allongé flexible conducteur 20, qui est le conducteur principal du courant électrique, assure une fonction ressort et une fonction plot de contact. Il peut être réalisé en une pièce, comme illustré sur la figure 2, ou en deux pièces, comme illustré sur la figure 3. Au moins une lame métallique 21 forme un complément de section pour le passage de courant électrique de façon à obtenir un doigt de structure simple dans un encombrement donné permettant le passage d'un maximum de courant nominal . In the device of the invention, as illustrated in FIGS. 2 and 3, a conductive flexible elongate contact element 20, which is the main conductor of the electric current, provides a spring function and a contact pad function. It can be made in one piece, as illustrated in FIG. 2, or in two pieces, as illustrated in FIG. 3. At least one metal blade 21 forms a complement of section for the passage of electric current so as to obtain a finger of simple structure in a given space allowing the passage of a maximum of nominal current.
L'élément de contact 20 comprend une première partie 22 en forme de tige et une seconde partie 23 en forme de plot de contact qui peuvent faire partie d'une même pièce ou former deux pièces séparées. Une première extrémité de la au moins une lame 21 est disposée entre la première pièce 10 et la première extrémité de la première partie de la pièce conductrice 20, elle-même reliée à cette première pièce 10 par l'intermédiaire de l'élément de jonction 16. Une seconde extrémité de la au moins une lame 21 est reliée à la seconde extrémité de la première partie 22 de l'élément de contact 20 par un élément de jonction mécanique et électrique 24. La au moins une lame de contact permet d'augmenter le courant nominal sans augmenter l'effort de contact. The contact element 20 comprises a first portion 22 in the form of a rod and a second portion 23 in the form of contact pads which can be part of the same part or two separate parts. A first end of the at least one blade 21 is disposed between the first part 10 and the first end of the first part of the conductive part 20, itself connected to this first part 10 via the joining element 16. A second end of the at least one blade 21 is connected to the second end of the first portion 22 of the contact element 20 by a mechanical and electrical connecting element 24. The at least one contact blade makes it possible to increase the nominal current without increasing the contact force.
La référence 25 représente la zone de contact entre la seconde partie 23 de l'élément de contact 20 et la surface conductrice 26 de la seconde pièce 11.  The reference 25 represents the contact zone between the second part 23 of the contact element 20 and the conductive surface 26 of the second part 11.
Les figures 4 à 6 illustrent des exemples de réalisation du premier et du second élément de jonction 16 et 24.  Figures 4 to 6 illustrate exemplary embodiments of the first and second junction elements 16 and 24.
1. premier élément de jonction 16, illustré sur la figure 4 :  1. first joining element 16, illustrated in FIG. 4:
Ce premier élément de jonction 16 peut être réalisé à l'aide d'une vis ou d'un rivet 30 reliant, l'élément de contact 20 et la ou les lames de contact 21 à la première pièce 10. Une seule liaison assure alors la jonction des trois éléments : première pièce 10, lames métalliques 21 et élément de contact 20.  This first joining element 16 can be made using a screw or a rivet 30 connecting the contact element 20 and the contact blade or blades 21 to the first part 10. A single connection then ensures the junction of the three elements: first part 10, metal blades 21 and contact element 20.
Dans le cas d'un effort de serrage important, pour limiter la contrainte de pression dans les matériaux conducteurs et/ou disposer d'une surface de passage de courant satisfaisante, on peut utiliser une rondelle de répartition d'effort 31 disposée sous la tête de vis ou de rivet.  In the case of a large clamping force, to limit the pressure stress in the conductive materials and / or have a satisfactory current flow area, one can use a force distribution washer 31 disposed under the head screw or rivet.
2. second élément de jonction 24, illustré sur les figures 5 et 6 : 2. second joining element 24, illustrated in FIGS. 5 and 6:
La seconde jonction de la lame ou des lames 21 et de l'élément de contact 20 peut être faite soit par rivet 40, comme illustré sur la figure 5, soit par sertissage et déformation d'une partie proéminente d'un plot de contact 50 inséré dans la ou les lames 21 et l'élément de contact 20, comme illustré sur la figure 6. Une autre solution efficace utilise un vissage pour les deux variantes considérées ci-dessus. Dans tous les cas les mêmes règles que celle du second point concernant le premier élément de jonction avec la première pièce s'appliquent. The second junction of the blade or blades 21 and the contact element 20 can be made either by rivet 40, as shown in Figure 5, or by crimping and deformation of a prominent portion of a contact pad 50 inserted into the blade (s) 21 and the contact element 20, as shown in Figure 6. Another effective solution uses a screw for both variants considered above. In all cases the same rules as the second point concerning the first connecting element with the first part apply.
Dans un exemple de réalisation avantageux, l'élément de contact 20 peut avoir une longueur comprise entre 3 et 15 cm, une épaisseur dans sa première partie 22 comprise entre 3 et 20 mm. Chaque lame métallique peut avoir une épaisseur comprise entre 0,1 mm et 1 mm. L'élément de contact 20 et les lames peuvent être réalisés en cuivre, en aluminium ou un de leurs alliages.  In an advantageous exemplary embodiment, the contact element 20 may have a length of between 3 and 15 cm, a thickness in its first portion 22 of between 3 and 20 mm. Each metal blade may have a thickness of between 0.1 mm and 1 mm. The contact element 20 and the blades may be made of copper, aluminum or one of their alloys.
