Description

La présente invention concerne les cosses destinées à enserrer les bornes des batteries d'accumulateur.The present invention relates to lugs intended to enclose the terminals of accumulator batteries.

Dans le but de relier les bornes de batteries d'accumulateur aux différents récepteurs d'énergie, il est connu d'utiliser des cosses que l'on serre sur chaque borne, à partir desquelles partent les fils électriques de liaison.In order to connect the terminals of accumulator batteries to the various energy receivers, it is known to use lugs which are tightened on each terminal, from which the electrical connecting wires leave.

Ces cosses peuvent être réalisées en matériau élastique souple, l'élasticité assurant le serrage sur la borne. Etant donné la nécessité d'une liaison efficace entre les éléments, les caractéristiques élastiques du matériau conducteur utilisé doivent être telles que l'on obtienne un pincement ou serrage très important ; il devient alors impossible d'enlever la cosse sans l'aide d'outils appropriés, ce qui rend le dispositif peu pratique.These lugs can be made of flexible elastic material, the elasticity ensuring tightening on the terminal. Given the need for an effective connection between the elements, the elastic characteristics of the conductive material used must be such that a very high pinch or tightening is obtained; it then becomes impossible to remove the terminal without using appropriate tools, which makes the device impractical.

On trouve également des cosses, fixées à l'aide de vis sur les bornes des batteries. Un système à vis-écrou peut alors être utilisé latéralement, pour relier les deux mâchoires des cosses. Le vissage vient rapprocher et serrer ces mâchoires autour de la borne. Une autre solution consiste à munir le dessus de la borne d'une tige filetée. La cosse, constituée d'un anneau métallique, vient s'encastrer dans la tige et un chapeau isolant, comprenant un orifice également fileté, se visse sur la tige de la borne de façon à coincer la cosse.There are also terminals, fixed with screws on the battery terminals. A screw-nut system can then be used laterally, to connect the two jaws of the terminals. The screwing brings these jaws together and tightens around the terminal. Another solution is to provide the top of the terminal with a threaded rod. The terminal, made up of a metal ring, is embedded in the rod and an insulating cap, comprising an orifice also threaded, is screwed on the rod of the terminal so as to wedge the terminal.

Les montages et démontages de ces différents systèmes à vis, nécessitent également l'utilisation d'outils, ce qui rend ces manipulations assez longues et peu aisées.The mounting and dismounting of these different screw systems also requires the use of tools, which makes these manipulations fairly long and not very easy.

Une cosse de batterie d'accumulateur amovible sans l'utilisation d'outils est, par exemple, connue de DE-A-3 403 400. Cette borne se compose de deux demi-pinces articulées entre lesquelles un ressort agit en permanence. L'une de demi-pinces est prolongée par un bras de manoeuvre.A removable battery terminal without the use of tools is, for example, known from DE-A-3 403 400. This terminal consists of two articulated half-clamps between which a spring acts permanently. One of the half-clamps is extended by an operating arm.

Une autre cosse formée de deux parties articulés sur lesquelles agit un ressort de torsion est connue de US-A-4 256 361.Another terminal formed of two articulated parts on which a torsion spring acts is known from US-A-4,256,361.

L'invention a pour object une cosse de batterie d'accumulateur, amovible rapidement sans l'utilisation d'outils quelconques.The object of the invention is a battery terminal, which can be quickly removed without the use of any tools.

Cette nouvelle cosse peut se monter sur n'importe quelle batterie standard. Elle permet des interventions de montage et démontage très rapides et très faciles assurant d'une part l'isolement rapide du circuit électrique du véhicule en cas de masse ou d'accident et ainsi éviter l'incendie du véhicule et permettant d'autre part un nettoyage aisé et une mise en charge correcte de la batterie. Le système de serrage utilisé assure un contact souple, mais néanmoins très efficace, entre la cosse et la borne.This new terminal can be mounted on any standard battery. It allows very quick and easy assembly and disassembly interventions ensuring on the one hand the rapid isolation of the vehicle's electrical circuit in the event of a mass or accident and thus avoiding vehicle fire and allowing on the other hand easy cleaning and proper loading of the drums. The clamping system used ensures flexible, but nevertheless very effective, contact between the terminal and the terminal.

Elle apporte une grande sécurité évitant tout contact entre les deux bornes de la batterie et une grande fiabilité par son système de pression constante et par sa robustesse.It provides great security avoiding contact between the two battery terminals and great reliability through its constant pressure system and its robustness.

Selon l'invention, la cosse pour batterie d'accumulateur comporte deux mâchoires articulées enserrant la borne et prolongées par deux bras de manoeuvre entre lesquels un organe élastique agit en permanence. Ces deux mâchoires sont articulées à une de leurs extrémités et prolongées, à leur autre extrémité, par les deux bras de manoeuvre qui s'entrecroisent. La borne est destinée à se placer entre l'articulation des deux mâchoires et le croisement des bras de manoeuvre.According to the invention, the terminal for an accumulator battery comprises two articulated jaws enclosing the terminal and extended by two operating arms between which an elastic member acts permanently. These two jaws are articulated at one of their ends and extended, at their other end, by the two operating arms which intersect. The terminal is intended to be placed between the articulation of the two jaws and the crossing of the operating arms.

Toujours selon l'invention une des branches latérales des bras de manoeuvre est muni d'un système à pince destiné au branchement d'un fil de liaison.Still according to the invention, one of the lateral branches of the operating arms is provided with a clamp system intended for the connection of a connecting wire.

Toujours selon l'invention la pince est réalisée par la branche latérale du bras et une platine mobile interposée entre la branche latérale et l'organe élastique.Still according to the invention, the clamp is produced by the lateral branch of the arm and a movable plate interposed between the lateral branch and the elastic member.

Selon une caractéristique supplémentaire, la platine mobile comporte au moins un orifice et la branche latérale au moins une tige, destinée à venir s'encastrer dans l'orifice, de façon à guider la platine mobile en translation.According to an additional characteristic, the movable plate comprises at least one orifice and the lateral branch at least one rod, intended to be fitted into the orifice, so as to guide the movable platen in translation.

De façon avantageuse, le bras et la platine mobile comportent des logements destinés à recevoir le fil de branchement ; l'organe élastique en forme de ressort est maintenu en place par encastrement de chacune de ses extrémités dans un bossage circulaire de diamètre légèrement inférieur à celui du ressort.Advantageously, the arm and the movable plate comprise housings intended to receive the connection wire; the spring-shaped elastic member is held in place by embedding each of its ends in a circular boss with a diameter slightly smaller than that of the spring.

Mais l'invention sera encore illustrée, sans être aucunement limitée, par la description suivante d'un mode de réalisation particulier, donné à titre d'exemple, et représenté sur les dessins annexés.

  • la figure 1 représente, vue de face, la cosse selon l'invention,
  • la figure 2 est une vue de côté de la figure 1,
  • la figure 3 est une vue de dessus de la figure 1,
  • la figure 4 est une vue en coupe selon A-B de la figure 1.
However, the invention will be further illustrated, without being in any way limited, by the following description of a particular embodiment, given by way of example, and shown in the accompanying drawings.
  • Figure 1 shows, front view, the terminal according the invention,
  • FIG. 2 is a side view of FIG. 1,
  • FIG. 3 is a top view of FIG. 1,
  • FIG. 4 is a sectional view along AB of FIG. 1.

La cosse 1 de batterie d'accumulateur représentée figures 1 à 4, comprend deux plaques de base 2 et 3, réalisées en métal conducteur coulé et moulé et par usinage des parties importantes, pour obtenir l'ossature générale du dispositif.The terminal 1 of the accumulator battery shown in FIGS. 1 to 4, comprises two base plates 2 and 3, made of cast and molded conductive metal and by machining the large parts, to obtain the general framework of the device.

Ces plaques de base 2 et 3 comportent chacune une partie en forme de demi-cercle 21 et 31.These base plates 2 and 3 each have a part in the shape of a semicircle 21 and 31.

La partie 31 en forme de demi-cercle, de la plaque de base 3, comporte, à son extrémité avant, un cylindre 33 en forme de tube, ayant une largeur a sensiblement égale à la moitié de la largeur b des plaques de base 2 et 3.The part 31 in the form of a semicircle, of the base plate 3, comprises, at its front end, a cylinder 33 in the form of a tube, having a width a substantially equal to half the width b of the base plates 2 and 3.

Ce cylindre 33 est disposé au milieu de l'extrémité de la partie 31.This cylinder 33 is placed in the middle of the end of the part 31.

L'extrémité arrière de cette partie 31 se prolonge par un bras de manoeuvre 32 en forme d'équerre.The rear end of this part 31 is extended by an operating arm 32 in the form of a square.

La partie 21 en forme de demi-cercle, de la plaque de base 2, comporte, à son extrémité avant, deux cylindres 23a et 23b. Ces deux cylindres 23a et 23b sont disposés latéralement au niveau de l'extrémité avant de la partie 21 en forme de demi-cercle ; ils ont une largeur c sensiblement égale au quart de la largeur b des plaques de base 2 et 3.The part 21 in the form of a semicircle, of the base plate 2, comprises, at its front end, two cylinders 23 a and 23 b . These two cylinders 23 a and 23 b are arranged laterally at the front end of the part 21 in the form of a semicircle; they have a width c substantially equal to a quarter of the width b of the base plates 2 and 3.

Les parties 33, 23a et 23b sont complémentaires et peuvent être réalisées par moulage puis usinage des parties importantes.The parts 33, 23a and 23b are complementary and can be produced by molding and then machining the large parts.

L'extrémité arrière de la partie 21 se prolonge par un bras de manoeuvre 22 en forme d'équerre.The rear end of the part 21 is extended by an operating arm 22 in the form of a square.

Lors du moulage des pièces on laisse un peu de matière au niveau des angles des bras de manoeuvre 22 et 32 pour les renforcer.When molding the parts, a little material is left at the angles of the operating arms 22 and 32 to reinforce them.

Toujours pour servir de renfort, le milieu extérieur de chaque partie 21 et 31 en forme de demi-cercle comporte un bossage 25, 26 d'épaisseur 1,5 mm, de largeur 3 mm et de forme bombée.Still to serve as reinforcement, the external medium of each part 21 and 31 in the form of a semicircle comprises a boss 25, 26 of thickness 1.5 mm, width 3 mm and of convex shape.

Chaque plaque 2 et 3 comporte un évidement central 24, 34, partant approximativement de l'angle des bras 22 et 32 en forme d'équerre et allant jusqu'à environ le début des parties 21 et 31 en forme de demi-cercle.Each plate 2 and 3 has a central recess 24, 34, starting approximately from the angle of the arms 22 and 32 in the form of a square and going until approximately the beginning of the parts 21 and 31 in the form of a semicircle.

Ces évidements 24 et 34 ont une profondeur sensiblement équivalente à la moitié de la largeur b des plaques 2 et 3 et sont réalisés sur ces plaques, de façon à permettre leur entrecroisement, pour obtenir l'assemblage tel que représenté sur les figures.These recesses 24 and 34 have a depth substantially equivalent to half the width b of the plates 2 and 3 and are made on these plates, so as to allow their intersection, to obtain the assembly as shown in the figures.

Les plaques 2 et 3 sont introduites l'une dans l'autre par l'intermédiaire des évidements 24 et 34, pour obtenir un dispositif d'épaisseur b.The plates 2 and 3 are introduced into each other via the recesses 24 and 34, to obtain a device of thickness b .

L'assemblage de ces deux plaques 2 et 3 constitue l'ossature générale de la cosse 1. Les parties 21, 31 en forme de demi-cercle, forment mâchoires et délimitent un orifice 4 de forme conique, destiné à recevoir la borne de la batterie.The assembly of these two plates 2 and 3 constitutes the general framework of the terminal 1. The parts 21, 31 in the form of a semicircle, form jaws and delimit an orifice 4 of conical shape, intended to receive the terminal of the drums.

Etant donné la structure de la cosse selon l'invention et l'entrecroisement des plaques 2 et 3, les bras de manoeuvre 22 et 32 se situent respectivement du même côté que les mâchoires 31 et 21. Les évidements 24 et 34 sont tels qu'ils permettent une certaine liberté de mouvement des plaques 2 et 3 entre elles.Given the structure of the terminal according to the invention and the intersection of the plates 2 and 3, the operating arms 22 and 32 are situated respectively on the same side as the jaws 31 and 21. The recesses 24 and 34 are such that they allow a certain freedom of movement of the plates 2 and 3 between them.

La surface interne des parties 21 et 31 est munie d'un renflement fin saillant 27 visible figure 4. Cette saillie 27 s'étend, après assemblage, sur tout le diamètre intérieur et inférieur de l'orifice conique 4, au niveau de la plus grande surface.The internal surface of the parts 21 and 31 is provided with a fine protruding bulge 27 visible in FIG. 4. This projection 27 extends, after assembly, over the entire inner and lower diameter of the conical orifice 4, at the level of the most big surface.

Lors du montage de la cosse sur la borne, cette partie saillante rentre dans le plomb de la borne de la batterie, évitant ainsi tout risque de glissement de bas en haut.When mounting the terminal on the terminal, this protruding part enters the lead of the battery terminal, thus avoiding any risk of sliding from bottom to top.

La réunion des bras de manoeuvre 22 et 32 présente une forme en U, vu de face, les branches latérales 221 et 321 du U s'étendant parallèlement vers l'arrière. Afin de renforcer la sécurité de la manipulation, les bras de manoeuvre 22 et 32 sont recouverts d'un film plastique isolant.The meeting of the operating arms 22 and 32 has a U shape, seen from the front, the lateral branches 221 and 321 of the U extending parallel backwards. In order to reinforce the safety of handling, the operating arms 22 and 32 are covered with an insulating plastic film.

La réunion des cylindres complémentaires 33, 23a et 23b, disposés à l'extrémité avant des mâchoires 21 et 31, délimite un orifice 5 destiné à recevoir un rivet 6 assurant l'articulation des mâchoires 21 et 31 autour d'un axe X.The meeting of complementary cylinders 33, 23a and 23b, arranged at the front end of the jaws 21 and 31, delimits an orifice 5 intended to receive a rivet 6 ensuring the articulation of the jaws 21 and 31 around an axis X.

Ce rivet 6 sera maté à ses extrémités tout en laissant libre le mouvement d'articulation.This rivet 6 will be matted at its ends while leaving free the movement of articulation.

Un organe élastique 7, en forme de ressort hélicoïdal, est disposé entre les branches latérales 221 et 321 des bras de manoeuvre 22 et 32. Ce ressort 7 agit en permanence et est destiné à maintenir l'écart entre ces branches latérales 221 et 321.An elastic member 7, in the form of a helical spring, is disposed between the lateral branches 221 and 321 of the operating arms 22 and 32. This spring 7 acts permanently and is intended to maintain the distance between these lateral branches 221 and 321.

Une pression manuelle, sur chaque branche latérale 221 et 321, tendant à compresser le ressort 7, provoque une ouverture des mâchoires 21 et 31, grâce à l'élasticité de l'ensemble, le croisement des bras 22 et 32, et à l'articulation de ces mâchoires autour de l'axe X.Manual pressure, on each lateral branch 221 and 321, tending to compress the spring 7, causes the jaws 21 and 31 to open, thanks to the elasticity of the assembly, the crossing of the arms 22 and 32, and to the articulation of these jaws around the X axis.

Un relâchement de cette compression provoque la fermeture des mâchoires 21 et 31. L'orifice 4 change donc de surface par simple compression ou relâchement du ressort 7.A relaxation of this compression causes the jaws 21 and 31 to close. The orifice 4 therefore changes surface by simple compression or relaxation of the spring 7.

En position d'équilibre, l'orifice 4 a une surface inférieure à la surface d'occupation de la borne de batterie. Ainsi, lorsque l'on désire placer la cosse sur la borne, il suffit d'appuyer latéralement sur les bras de manoeuvre 22 et 32, de façon à comprimer le ressort, de positionner ensuite la borne dans l'orifice cylindrique 4 et de relâcher enfin les bras 22 et 32 de façon à ce que le ressort tende à revenir à sa position d'équilibre et à ce que les mâchoires 21 et 31 enserrent la borne.In the equilibrium position, the orifice 4 has a surface less than the surface of occupation of the battery terminal. Thus, when it is desired to place the terminal on the terminal, it suffices to press laterally on the operating arms 22 and 32, so as to compress the spring, then to position the terminal in the cylindrical orifice 4 and to release finally the arms 22 and 32 so that the spring tends to return to its equilibrium position and so that the jaws 21 and 31 grip the terminal.

On peut noter, figures 1 et 3, que l'organe élastique 7 agit sur la branche latérale 221 par l'intermédiaire d'une platine 8.It can be noted, FIGS. 1 and 3, that the elastic member 7 acts on the lateral branch 221 by means of a plate 8.

Cette platine 8 est mobile et comporte deux orifices 81.This plate 8 is mobile and has two orifices 81.

Deux tiges 9 s'étendent à partir de la branche latérale 221 et viennent s'encastrer dans ces orifices 81 pour guider la platine 8 en translation.Two rods 9 extend from the lateral branch 221 and come to be embedded in these orifices 81 to guide the plate 8 in translation.

La branche 221 et la platine 8 sont serrées l'une contre l'autre par le ressort 7 et ces deux pièces sont destinées à pincer un fil de branchement 10.The branch 221 and the plate 8 are clamped against one another by the spring 7 and these two parts are intended to pinch a connection wire 10.

La branche 221 et la platine 8 comportent à cet effet des logements 11 destinés à maintenir le fil 10 en place.The branch 221 and the plate 8 for this purpose have housings 11 intended to hold the wire 10 in place.

La surface interne de ces logements 11 sera striée afin d'éviter le glissement ou l'arrachement du fil 10.The internal surface of these housings 11 will be striated in order to avoid slipping or tearing of the wire 10.

Le ressort 7 est en appui sur les côtés internes de la branche latérale 321 et de la platine 8 et assure, d'une part l'écartement des branches latérales 221 et 321 et d'autre part le pincement du fil entre la platine 8 et la branche 221.The spring 7 bears on the internal sides of the lateral branch 321 and of the plate 8 and ensures, on the one hand the spacing of the lateral branches 221 and 321 and on the other hand the nipping of the wire between the plate 8 and branch 221.

Afin de maintenir ce ressort 7 en place, les côtés internes de la platine 8 et de la branche latérale 321 sont chacun munis d'un bossage circulaire 71, 72 d'épaisseur 1,5 mm environ et d'un diamètre légèrement inférieur à celui du ressort 7, qui s'y encastrera.In order to keep this spring 7 in place, the internal sides of the plate 8 and of the lateral branch 321 are each provided with a circular boss 71, 72 with a thickness of approximately 1.5 mm and a diameter slightly smaller than that of spring 7, which will fit there.

Bien entendu, l'invention ne se limite pas au détail des modes de réalisation qui n'ont été décrits qu'à titre d'exemple, mais elle couvre également les réalisations qui n'en diffèreraient que par des détails, des variantes d'exécution ou l'utilisation de moyens équivalents.Of course, the invention is not limited to the detail of the embodiments which have only been described by way of example, but it also covers the embodiments which would differ from it only in details, variants of execution or use of equivalent means.

C'est ainsi par exemple que l'organe élastique, décrit et représenté sur les différentes figures, est en forme de ressort hélicoïdal. Toute autre forme ou moyen élastique pourra néanmoins être utilisé de façon tout à fait équivalente. On peut par exemple utiliser une lame courbe, élastique, reliant les deux branches latérales.Thus, for example, the elastic member, described and shown in the various figures, is in the form of a helical spring. Any other form or elastic means may nevertheless be used in a completely equivalent manner. One can for example use a curved, elastic blade, connecting the two lateral branches.

L'exemple de réalisation décrit, propose le guidage en translation de la partie mobile, au moyen de deux tiges s'étendant à partir de la branche latérale. Il est bien évident que le nombre de ces tiges pourra varier et que par exemple une seule tige, associée à un orifice sur la platine 8, sera suffisant pour assurer ce guidage.The exemplary embodiment described proposes guiding in translation of the mobile part, by means of two rods extending from the lateral branch. It is obvious that the number of these rods may vary and that for example a single rod, associated with an orifice on the plate 8, will be sufficient to provide this guidance.

La forme des mâchoires sera adaptée à la forme de la borne. Celle-ci pourra être cylindrique ou polygonale et dans ce cas, les mâchoires auront une forme complémentaire pour assurer un contact maximum entre les deux éléments.The shape of the jaws will be adapted to the shape of the terminal. This can be cylindrical or polygonal and in this case, the jaws will have a complementary shape to ensure maximum contact between the two elements.

Les signes de référence insérés après les caractéristiques techniques mentionnées dans les revendications ont pour seul but de faciliter la compréhension de ces dernières, et n'en limitent aucunement la portée.The reference signs inserted after the technical characteristics mentioned in the The claims are intended only to facilitate understanding of the latter, and in no way limit their scope.
