Description

VIS DE BORNETERMINAL SCREWS
La présente invention concerne le domaine des vis de borne, c'est-à-dire les vis à fonction de conduction électrique.The present invention relates to the field of terminal screws, that is to say screws with an electrical conduction function.
Plus précisément encore, la présente invention concerne le domaine des vis conçues pour assurer un contact électrique intermittent dans le circuit d'allumage d'un moteur à combustion interne.More specifically, the present invention relates to the field of screws designed to provide intermittent electrical contact in the ignition circuit of an internal combustion engine.
A l'origine, les vis destinées à cette application ont été réalisées en un matériau homogène, par exemple intégralement en cuivre, bronze ou acier. Cependant, le cahier des charges imposé pour les vis bornes s'est sévérisé ces dernières années. Il est ainsi demandé une résistance au contact électrique et à l'étincellage supérieure, pour garantir une usure moindre aux arcs électriques. Il est également demandé une résistance mécanique supérieure pour permettre d'admettre des couples de serrage plus élevé que par le passé. Enfin, il est généralement requis le passage d'un courant électrique d'intensité supérieure et donc une conduction électrique plus élevée.Originally, the screws intended for this application were made of a homogeneous material, for example entirely of copper, bronze or steel. However, the specifications imposed for terminal screws have become more stringent in recent years. Resistance to electrical contact and higher sparking is thus required, to guarantee less wear on the electric arcs. It is also required a higher mechanical resistance to allow to admit higher tightening torques than in the past. Finally, it is generally required the passage of an electric current of higher intensity and therefore a higher electrical conduction.
De là, les spécialistes ont proposé ces derniers temps des vis bi- matière, c'est-à-dire des vis dont le corps principal est réalisé en acier, mais avec une tête creuse adaptée au brasage d'une pastille en alliage d'argent/tungstène brasée sur la tête.From there, specialists have recently proposed bi-material screws, that is to say screws whose main body is made of steel, but with a hollow head suitable for brazing a wafer made of an alloy of silver / tungsten brazed on the head.
Techniquement ces vis bi-matière à base d'acier comportant une pastille en argent/tungstène brasée donnent satisfaction.Technically, these bi-material steel-based screws with a brazed silver / tungsten pad give satisfaction.
Cependant, ces vis soulèvent une difficulté majeure qui est leur coût élevé. Ce coût est dû entre autres à l'argent / tungstène : coût matière très élevé et à la nécessité de gérer deux composants : d'une part, le corps en acier, d'autre part, la pastille en argent/tungstène, et résulte également du processus d'assemblage. -However, these screws raise a major difficulty which is their high cost. This cost is due inter alia to silver / tungsten: very high material cost and the need to manage two components: on the one hand, the steel body, on the other hand, the silver / tungsten pellet, and results also of the assembly process. -
La présente invention a maintenant pour but de proposer une nouvelle vis borne apte à répondre à un cahier des charges sévère, et de coût acceptable.The object of the present invention is now to propose a new terminal screw capable of meeting strict specifications, and of acceptable cost.
La présente invention a notamment pour but de proposer une vis borne répondant au cahier des charges suivant : - résistance mécanique supérieure à 580MPa,The object of the present invention is in particular to propose a terminal screw meeting the following specifications: - mechanical resistance greater than 580MPa,
- une conductivité supérieure à 25% IACS, et- a conductivity greater than 25% IACS, and
- un couple de serrage supérieur à 15 Nm.- a tightening torque greater than 15 Nm.
Les buts précités sont atteints dans le cadre de la présente invention, grâce à une vis borne monobloc caractérisée par le fait qu'elle est réalisée en un alliage de cuivre à base de Cu, Ni, Si.The aforementioned aims are achieved in the context of the present invention, thanks to a one-piece terminal screw characterized in that it is made of a copper alloy based on Cu, Ni, Si.
Selon une caractéristique avantageuse de la présente invention, la vis borne est réalisée à l'aide d'un alliage comprenant de l'ordre de 97% de cuivre, de 2 à 5% de nickel, typiquement de 2,5% et de 0,3 à 1% de silicium, typiquement 0,5% .According to an advantageous characteristic of the present invention, the terminal screw is produced using an alloy comprising of the order of 97% copper, 2 to 5% nickel, typically 2.5% and 0 , 3 to 1% silicon, typically 0.5%.
D'autres caractéristiques, buts et avantages de la présente invention apparaîtront à la lecture de la description détaillée qui va suivre, et en regard du dessin annexé, donné à titre d'exemple non limitatif et sur lequel la figure unique annexée représente schématiquement une vis conforme à la présente invention.Other characteristics, objects and advantages of the present invention will appear on reading the detailed description which follows, and with reference to the appended drawing, given by way of nonlimiting example and in which the single appended figure schematically represents a screw according to the present invention.
La vis borne 10 conforme à la présente invention est monobloc et formée en un matériau homogène à base d'un alliage de cuivre nickel silicium.The terminal screw 10 according to the present invention is in one piece and formed from a homogeneous material based on a copper nickel silicon alloy.
Plus précisément, comme indiqué précédemment, de préférence la vis 10 conforme à la présente invention est réalisée à base d'un alliage comprenant de l'ordre de 97% de cuivre, de 2 à 5% de nickel, typiquement 2,5% et de 0,3 à 1% de silicium, typiquement 0,5%.More precisely, as indicated above, preferably the screw 10 in accordance with the present invention is produced based on an alloy comprising of the order of 97% copper, 2 to 5% nickel, typically 2.5% and from 0.3 to 1% of silicon, typically 0.5%.
De préférence, dans le cadre de la présente invention, la vis 10 est réalisée à partir d'un fil circulaire de section constante et une frappe à froid, par exemple deux coups.Preferably, in the context of the present invention, the screw 10 is made from a circular wire of constant section and a cold strike, for example two strokes.
Après ce processus de fabrication traditionnelle, la vis est de préférence l'objet d'un traitement thermique pendant deux heures à une température de l'ordre de 475°C, suivi d'une trempe à l'eau.After this traditional manufacturing process, the screw is preferably subjected to a heat treatment for two hours at a temperature of the order of 475 ° C., followed by quenching with water.
A priori, les inventeurs ont déterminé qu'aucune finition particulière n'est nécessaire.A priori, the inventors have determined that no particular finish is necessary.
On va maintenant décrire la géométrie générale de la vis borne conforme à un mode de réalisation particulier et non limitatif de la présente invention. Celle-ci comprend un corps fileté 12 centré sur un axe 14.We will now describe the general geometry of the terminal screw according to a particular and non-limiting embodiment of the present invention. This includes a threaded body 12 centered on an axis 14.
Typiquement mais non limitativement, le corps fileté ou tige 12 possède une longueur de l'ordre de 30 à 35 mm et un diamètre de l'ordre de 8mm. La tige ou corps 12 peut être adapté pour être engagé directement dans un alésage taraudé. Néanmoins, dans la majorité des cas d'utilisation des vis bornes dans un circuit d'allumage d'un moteur à combustion, la vis est immobilisée à l'aide d'un écrou engagé sur l'extrémité de la tige filetée 12. La vis 10 comporte par ailleurs une tête évasée 16 dont la section droite est non circulaire de révolution pour permettre une fonction anti-rotation, par exemple par engagement dans un evidement complémentaire ménagé dans le capot de contacteur.Typically but not limited to, the threaded body or rod 12 has a length of the order of 30 to 35 mm and a diameter of the order of 8mm. The rod or body 12 can be adapted to be engaged directly in a tapped bore. However, in most cases of using terminal screws in an ignition circuit of a combustion engine, the screw is immobilized using a nut engaged on the end of the threaded rod 12. The screw 10 further comprises a flared head 16 whose cross section is non-circular in revolution to allow an anti-rotation function, for example by engagement in a complementary recess formed in the contactor cover.
La tête 16 peut présenter une section droite de géométrie diverse, par exemple carrée, hexagonale, ou toute autre forme équivalente non circulaire de révolution.The head 16 may have a cross section of diverse geometry, for example square, hexagonal, or any other equivalent non-circular shape of revolution.
Les dimensions de la tête 16 peuvent faire l'objet de nombreuses variantes. Typiquement la tête 16 possède une hauteur de l'ordre de 5mm (considéré parallèlement à l'axe 14) et des dimensions de l'ordre de 13x10mm pour une tête de section rectangulaire.The dimensions of the head 16 can be the subject of numerous variants. Typically the head 16 has a height of the order of 5mm (considered parallel to the axis 14) and dimensions of the order of 13x10mm for a head of rectangular section.
La surface supérieure 18 de la tête 16, c'est-à-dire la surface perpendiculaire à l'axe 14 et assurant la fonction de contactage électrique est de préférence plane, sans bavure et brut de frappe. Il est important qu'elle ne présente pas de concavité. Elle peut ainsi être au moins légèrement bombée, convexe. De Plus elle est lisse.The upper surface 18 of the head 16, that is to say the surface perpendicular to the axis 14 and ensuring the electrical contacting function is preferably flat, without burrs and rough striking. It is important that it has no concavity. It can thus be at least slightly convex, convex. In addition it is smooth.
Les arêtes de la tête 16 à la fois parallèles à l'axe 14 et perpendiculaires à cet axe, sont de préférence arrondies avec un rayon moyen de l'ordre de 0,40 à 0,50mm.The edges of the head 16 both parallel to the axis 14 and perpendicular to this axis, are preferably rounded with an average radius of the order of 0.40 to 0.50mm.
Comme on l'a indiqué précédemment, la vis borne 10 conforme à la présente invention est réalisée de préférence à partir d'un fil circulaire.As indicated above, the terminal screw 10 according to the present invention is preferably made from a circular wire.
Le procédé de fabrication de la vis borne 10 conforme à la présente invention comprend essentiellement trois phases. La première phase consiste à tréfiler le fil circulaire déroulé de la bobine d'origine pour obtenir le diamètre et la résistance mécanique souhaités.The method of manufacturing the terminal screw 10 in accordance with the present invention essentially comprises three phases. The first phase consists of drawing the circular wire unwound from the original coil to obtain the desired diameter and mechanical strength.
Cette étape est typiquement opérée pour obtenir, selon un mode de réalisation particulier et non limitatif, un fil répondant aux caractéristiques suivantes :This step is typically carried out to obtain, according to a particular and nonlimiting embodiment, a wire meeting the following characteristics:
- diamètre de 7,5mm pour une vis finale de diamètre 8mm,- 7.5mm diameter for a final screw with a diameter of 8mm,
- charge de rupture R en Mpa : 320 à 400,- breaking load R in Mpa: 320 to 400,
- limite d'élasticité E à 0,2% Mpa : 290-380, - allongement : 10-20%,- elastic limit E at 0.2% Mpa: 290-380, - elongation: 10-20%,
- dureté Vickers HV10 : 105 à 125.- Vickers HV10 hardness: 105 to 125.
La deuxième étape consiste à opérer la frappe du fil, pour obtenir la géométrie souhaitée de vis et écrouir. Il s'agit de préférence d'une frappe à froid, par exemple deux coups. La troisième étape consiste à opérer un traitement thermique pour obtenir une résistance mécanique et une conductivité électrique adéquates.The second step is to strike the wire, to obtain the desired geometry of the screw and work hardening. It is preferably a cold strike, for example two strokes. The third step is to operate a heat treatment to obtain adequate mechanical strength and electrical conductivity.
De préférence, le traitement thermique est opéré par maintien à une température de l'ordre de 475°C pendant deux heures, c'est-à-dire maintien des pièces à température constante puis refroidissement rapide, à l'air, voir à l'huile, de préférence à l'eau.Preferably, the heat treatment is carried out by maintaining at a temperature of the order of 475 ° C. for two hours, that is to say maintaining the parts at constant temperature then rapid cooling with air, see oil, preferably water.
Le cas échéant, les pièces peuvent être l'objet d'un nettoyage avant utilisation.If necessary, the parts can be cleaned before use.
La Demanderesse a constaté que les vis bornes réalisées avec la géométrie, l'alliage et le procédé précité, présentent des caractéristiques supérieures aux vis jusqu'ici proposées selon l'état de la technique.The Applicant has found that the terminal screws produced with the geometry, the alloy and the aforementioned method have characteristics superior to the screws hitherto proposed according to the state of the art.
Bien entendu la présente invention n'est pas limitée au mode de réalisation particulier qui vient d'être décrit mais s'étend à toute variante conforme à son esprit. Of course the present invention is not limited to the particular embodiment which has just been described but extends to any variant in accordance with its spirit.
