Description

COSSE DE RACCORDEMENT A UNE BATTERIE  CONNECTING TERMINAL TO A BATTERY
La présente invention entre dans le domaine des cosses de batteries . The present invention is in the field of battery terminals.
Plus particulièrement, l'invention est relative à une cosse de raccordement à une batterie, notamment une batterie de véhicule à moteur .  More particularly, the invention relates to a connection terminal to a battery, in particular a motor vehicle battery.
Il existe déjà, dans l'état de la technique, des cosses de raccordement à une batterie. Pour la plupart, le serrage est réalisé par un abord latéral, ce qui peut constituer un inconvénient selon 1 ' emplacement de la batterie .  In the state of the art, lugs for connecting to a battery already exist. For the most part, the tightening is achieved by a lateral approach, which may be a disadvantage depending on the location of the battery.
D'autres ont proposé la possibilité d'un serrage par un abord axial.  Others have proposed the possibility of clamping by an axial approach.
En particulier, on connaît la demande internationale publiée sous le numéro WO 2015/161943 qui divulgue une cosse, en particulier pour une batterie de véhicule à moteur, avec :  In particular, it is known the international application published under the number WO 2015/161943 which discloses a lug, in particular for a motor vehicle battery, with:
- une première bague de serrage fendue qui, à l'état monté, entoure au moins partiellement un pôle de la batterie et  a first split ring which, in the mounted state, at least partially surrounds a pole of the battery and
au moins deux mâchoires de serrage formées pour accueillir les outils de serrage et moulées sur la première bague de serrage, les outils de serrage générant alors , via les mâchoires , un mouvement radial dirigé vers l'intérieur et un resserrement de ladite première bague de serrage, et  at least two clamping jaws formed to receive the clamping tools and molded on the first clamping ring, the clamping tools then generating, via the jaws, a radial inward movement and a tightening of said first clamping ring , and
- une deuxième bague de serrage fendue qui, à l'état monté, entoure au moins partiellement le pôle de la batterie , avec ,  a second split ring which, in the mounted state, at least partially surrounds the pole of the battery, with,
- entre la première bague de serrage et la deuxième bague de serrage une liaison active formée de sorte que la deuxième bague de serrage suive un mouvement radial dirigé vers l'intérieur de la première bague de serrage .  - Between the first clamping ring and the second clamping ring an active connection formed so that the second clamping ring follows a radial movement directed towards the inside of the first clamping ring.
Ainsi, dans ce document de brevet, il est procédé à une déformation radiale des bagues par un serrage axial . En d' autres termes , la déformation du cône ou du cylindre, formé par les bagues, est effectuée par une réduction du diamètre dudit cône. Thus, in this patent document, the rings are radially deformed by axial clamping. In other words, the deformation of the cone or cylinder, formed by the rings, is effected by a reduction in the diameter of said cone.
Toutefois, cette conception présente l'inconvénient de nécessiter le montage d'une pluralité de pièces, notamment deux bagues de serrage, dont l'une seulement comporte deux mâchoires de serrage, ce qui est susceptible d'engendrer des coûts importants .  However, this design has the disadvantage of requiring the assembly of a plurality of parts, including two clamping rings, one of which has two clamping jaws, which is likely to generate significant costs.
En outre, une telle conception nécessite de prévoir une liaison active entre les deux bagues de serrage, par exemple au moyen d' emboîtements d'empreintes mâles-femelles concordantes, afin de permettre un transfert des forces de serrage radiales dirigées vers 1 ' intérieur , de la première bague de serrage vers la deuxième bague.  In addition, such a design requires to provide an active connection between the two clamping rings, for example by means of concordant male-female finger interlockings, in order to allow a transfer of the radial clamping forces directed towards the inside, from the first clamping ring to the second ring.
On connaît également, du document JP 2004-235135 une cosse de batterie destinée à entourer une borne de batterie, ladite cosse étant composée notamment d' un corps de cosse de batterie avec une paire d' éléments en forme d' anneaux destinés à entourer ladite borne, d'éléments de connexion et d'un moyen de serrage .  Document JP 2004-235135 also discloses a battery lug intended to surround a battery terminal, said lug being composed in particular of a battery lug body with a pair of ring-shaped elements intended to surround said battery terminal. terminal, connection elements and a clamping means.
Les éléments de connexion présentent une forme courbée en U et sont séparés par un espace, et forment un trou d'insertion d'un boulon.  The connecting members have a U-shaped curved shape and are spaced apart by a gap, and form a bolt insertion hole.
Les extrémités extérieures des éléments de connexion forment des portions de contact glissant au travers de surfaces inclinées , avec lesquelles viennent coopérer les surfaces inclinées d'un crochet supérieur tandis qu'une plaque plane est positionnée par le dessous des éléments de connexion.  The outer ends of the connecting elements form sliding contact portions through inclined surfaces, with which the inclined surfaces of an upper hook cooperate, while a flat plate is positioned from below the connecting elements.
Le verrouillage du moyen de serrage, au moyen du vissage d'un écrou, entraine un rapprochement des deux éléments de connexion et le contact glissant entre le crochet supérieur et les surfaces inclinées des éléments de connexion permet une transformation de la force allant du haut vers le bas vers une force droite-gauche entrainant un rapprochement des éléments de connexion. Toutefois , du fait du rapprochement des éléments de connexion, les contacts entre les surfaces inclinées du crochet supérieur et les portions de contact glissant des éléments de connexion ne peuvent demeurer plans, ce qui entraine une rupture des contacts au cours du temps aboutissant à un serrage de mauvaise qualité. The locking of the clamping means, by means of the screwing of a nut, causes a bringing together of the two connecting elements and the sliding contact between the upper hook and the inclined surfaces of the connecting elements allows a transformation of the force from the top to the down to a right-left force causing a rapprochement of the connection elements. However, because of the approximation of the connection elements, the contacts between the inclined surfaces of the upper hook and the sliding contact portions of the connection elements can not remain flat, which causes a break of the contacts over time resulting in a tightening bad quality.
Pour pallier cet inconvénient, le document de brevet JP 2008-97903 propose de remplacer le crochet supérieur unique par deux pièces articulées en pivotement autour de la vis du boulon et comportant chacune une portion de surface glissant, coopérant chacune avec une surface inclinée d'un élément de connexion, en sorte que lesdites pièces articulées puissent suivre la déformation et le déplacement des portions de contact glissant des éléments de connexion.  To overcome this drawback, patent document JP 2008-97903 proposes to replace the single upper hook by two pivotally articulated parts around the bolt screw and each having a sliding surface portion, each cooperating with an inclined surface of a connecting element, so that said articulated parts can follow the deformation and displacement of the sliding contact portions of the connecting elements.
Toutefois, en contrepartie, la présence nécessaire de deux pièces articulées l'une à l'autre entraine une complexification dans la conception du produit.  However, in return, the necessary presence of two parts articulated to each other leads to a complexification in the product design.
En outre, les deux pièces articulées étant pressées l'une contre l'autre lors du serrage du boulon, et l'accroissement de ce serrage ne favorise pas leur pivotement et leur positionnement par rapport aux portions de contact glissant des éléments de connexion.  In addition, the two articulated parts being pressed against each other during tightening of the bolt, and the increase in this clamping does not promote their pivoting and their positioning relative to the sliding contact portions of the connecting elements.
La présente invention vise à remédier à ces inconvénients tout en proposant une cosse de batterie présentant une facilité au montage et au démontage sur une batterie, et où le serrage s'effectue selon un abord axial.  The present invention aims to remedy these drawbacks while proposing a battery terminal having an easy assembly and disassembly on a battery, and where the clamping takes place at an axial approach.
A cet effet, la présente invention a pour objet une cosse de raccordement à une batterie, plus particulièrement de batterie de véhicule à moteur, comprenant des bornes cylindriques ou coniques , comportant une bague ouverte définissant une fente, ladite cosse étant caractérisée en ce qu'elle comprend, d'une part, des extensions radiales de part et d'autre de ladite fente, lesdites extensions présentant la forme d'un cylindre fendu longitudinalement dans le prolongement de la fente de la bague, et, d'autre part, deux moyens d' enserrement des deux extensions , chacun des moyens d' enserrement étant en contact tangent avec chacune des deux extensions , lesdits moyens d' enserrement étant associés à des moyens de serrage d' action parallèle à l'axe de ladite bague et conçus aptes à rapprocher les moyens d' enserrement . To this end, the subject of the present invention is a connection terminal for a battery, more particularly a motor vehicle battery, comprising cylindrical or conical terminals, comprising an open ring defining a slot, said terminal being characterized in that it comprises, on the one hand, radial extensions on either side of said slot, said extensions having the shape of a cylinder split longitudinally in the extension of the slot of the ring, and, on the other hand, two means for clamping the two extensions, each of the clamping means being in tangent contact with each of the two extensions, said clamping means being associated with means for clamping action parallel to the axis of said ring and designed to bring the clamping means closer together.
De préférence, lesdits moyens d' enserrement consistent en deux mâchoires comprenant chacune deux mors faisant entre eux un angle fermé et venant, chacun, en contact tangent avec la surface extérieure courbe de l'une des extensions.  Preferably, said gripping means consist of two jaws each comprising two jaws forming between them a closed angle and coming, each in tangential contact with the curved outer surface of one of the extensions.
Avantageusement, les moyens de serrage consistent en une vis qui réunit les deux moyens d' enserrement , ladite vis passant entre les deux extensions radiales parallèlement à l'axe de la bague , chaque moyen d' enserrement comportant un trou traversé par ladite vis, le trou du moyen d' enserrement traversé par la vis en second étant taraudé.  Advantageously, the clamping means consist of a screw which joins the two gripping means, said screw passing between the two radial extensions parallel to the axis of the ring, each gripping means comprising a hole traversed by said screw, the hole of the entanglement means traversed by the second screw being threaded.
La cosse de batterie selon l'invention, notamment au travers des deux moyens d' enserrement , de préférence identiques, qui sont en contact tangent avec chacune des deux extensions radiales de part et d'autre de la fente de la bague, présente notamment l'avantage de réduire le frottement entre les pièces, et de diminuer les efforts à appliquer pour le serrage.  The battery lug according to the invention, in particular through the two preferably identical clamping means, which are in tangential contact with each of the two radial extensions on either side of the slot of the ring, has in particular the advantage of reducing the friction between the parts, and reducing the forces to be applied for clamping.
En outre, la cosse de batterie de l'invention est de conception simple et représente, par conséquent, un coût inférieur à celui des cosses existantes. En outre, la cosse de batterie de l'invention est aisément montable ou démontable par un serrage ou desserrage axial .  In addition, the battery lug of the invention is of simple design and therefore represents a lower cost than existing lugs. In addition, the battery terminal of the invention is easily mountable or removable by axial clamping or loosening.
La présence de deux moyens d' enserrement identiques assurant le serrage de la cosse, l'un agissant par le haut et le second agissant par le bas , permet d' éviter de créer un déséquilibre entre le haut et le bas de la cosse, pouvant fragiliser de manière plus importante la partie au niveau de laquelle s'effectue le serrage, ce qui peut se produire dans certains dispositifs proposés dans l'état de la technique.  The presence of two identical clamping means ensuring the tightening of the lug, one acting from the top and the second acting from the bottom, makes it possible to avoid creating an imbalance between the top and the bottom of the terminal, being able to to weaken more significantly the part at which the clamping takes place, which may occur in some devices proposed in the state of the art.
D'autres caractéristiques et avantages de l'invention ressortiront de la description détaillée qui va suivre des modes de réalisation non limitatifs de l'invention, en référence aux figures annexées dans lesquelles : - la figure 1 illustre schématiquement et en perspective une vue éclatée d'un mode de réalisation de la cosse de raccordement à une batterie et d'un moyen de serrage ;Other characteristics and advantages of the invention will emerge from the following detailed description of non-limiting embodiments of the invention, with reference to the appended figures in which: - Figure 1 illustrates schematically and in perspective an exploded view of an embodiment of the battery connection lug and a clamping means;
- la figure 2 illustre schématiquement une vue de face d'un mode de réalisation de la cosse de raccordement à une batterie ; - Figure 2 schematically illustrates a front view of an embodiment of the connection terminal to a battery;

- la figure 4 illustre schématiquement et en perspective un mode de réalisation d'un détail de la cosse de raccordement à une batterie.  - Figure 4 schematically illustrates in perspective an embodiment of a detail of the connection terminal to a battery.
Ainsi, telle que représentée sur la figure 1, la présente invention a pour objet une cosse 1 de raccordement à une batterie, par exemple une batterie de véhicule à moteur comprenant des bornes , ou pôles , cylindriques ou coniques .  Thus, as shown in FIG. 1, the present invention relates to a lug 1 for connection to a battery, for example a motor vehicle battery comprising cylindrical or conical terminals or poles.
La présente cosse de batterie 1 consiste, plus particulièrement, en une cosse se montant et se démontant aisément par un serrage axial, sur une borne de batterie.  The present battery lug 1 consists, more particularly, in a lug easily mounting and dismounting by axial clamping, on a battery terminal.
En référence aux figures 1 et 2 , la cosse de batterie 1 comporte une bague de serrage 2, qui, à l'état monté, vient entourer, au moins partiellement, une borne de la batterie, non représentée sur les figures .  Referring to Figures 1 and 2, the battery lug 1 comprises a clamping ring 2, which, in the mounted state, surrounds, at least partially, a terminal of the battery, not shown in the figures.
Ladite bague de serrage 2 est ouverte en sorte de définir une fente 3, visible, elle, sur la figure 3.  Said clamping ring 2 is open so as to define a slot 3, visible in FIG. 3.
La cosse de raccordement 1 à une batterie de l'invention comprend au moins deux extensions radiales 4 , 5 prolongeant la bague de serrage 2 de part et d' autre de la fente 3.  The connecting lug 1 to a battery of the invention comprises at least two radial extensions 4, 5 extending the clamping ring 2 on either side of the slot 3.
Comme visible plus particulièrement sur les figures 1 à 3, ces extensions radiales 4, 5 de la cosse de batterie 1 présentent la forme d'un cylindre fendu longitudinalement, dans le prolongement de la fente 3 de la bague de serrage 2.  As seen more particularly in FIGS. 1 to 3, these radial extensions 4, 5 of the battery lug 1 have the shape of a longitudinally split cylinder, in the extension of the slot 3 of the clamping ring 2.
Ce cylindre fendu peut être obtenu, tout comme la fente 3 de la bague de serrage 2, par une opération d'usinage de la cosse, de type sciage. De manière avantageuse , outre ces extensions radiales 4 , 5, la cosse 1 selon l'invention comporte également deux moyens d' enserrement 6, 7 illustrés sur les figures 1 et 2 en association avec les autres éléments de ladite cosse 1, l'un de ces moyens d' enserrement 6 étant représenté plus en détail sur l'agrandissement de la figure 4. This split cylinder can be obtained, like the slot 3 of the clamping ring 2, by a machining operation of the lug, sawing type. Advantageously, in addition to these radial extensions 4, 5, the lug 1 according to the invention also comprises two clasping means 6, 7 illustrated in FIGS. 1 and 2 in association with the other elements of said lug 1, one of these clasping means 6 being shown in greater detail on the enlargement of FIG. 4.
En référence, à présent, plus particulièrement à la figure 2 , chacun de ces moyens d' enserrement 6 , 7 est en contact tangent avec chacune des deux extensions radiales , 5.  Referring now, more particularly to FIG. 2, each of these clasping means 6, 7 is in tangential contact with each of the two radial extensions, 5.
Plus préférentiellement , afin d'assurer un tel contact tangent entre les moyens d' enserrement 6 , 7 et les extensions radiales 4 , 5 de la cosse de batterie 1 , lesdits moyens d' enserrement 6, 7 consistent en des mâchoires comprenant, chacune deux mors, ceux-ci présentant, entre eux, un angle fermé et venant, chacun, en contact tangent avec la surface extérieure courbe, incurvée, de l'une des deux extensions 4, 5.  More preferably, in order to ensure such tangent contact between the clasping means 6, 7 and the radial extensions 4, 5 of the battery lug 1, said clipping means 6, 7 consist of jaws each comprising two jaws, these having, between them, a closed angle and coming, each in tangential contact with the curved outer curved surface of one of the two extensions 4, 5.
En d'autres termes, le moyen d' enserrement 6 supérieur, venant enserrer les extensions 4, 5 par le dessus de celles-ci, consiste en une mâchoire comprenant deux mors 61, 62, visibles de manière détaillée sur la figure 4 , tandis que le moyen d' enserrement inférieur 7 , venant enserrer lesdites extensions 4, 5 par le dessous de celles-ci, présente également deux mors 71 et 72. Les deux moyens d' enserrement supérieur 6 et inférieur 7 sont donc de conception identique.  In other words, the upper gripping means 6, gripping the extensions 4, 5 from above, consists of a jaw comprising two jaws 61, 62, which can be seen in detail in FIG. that the lower gripping means 7, gripping said extensions 4, 5 from below, also has two jaws 71 and 72. The two upper and lower gripping means 6 and 7 are therefore of identical design.
Les moyens d' enserrement 6, 7 vont donc venir serrer la cosse de batterie 1 , en venant au contact des extensions radiales de celle-ci, le serrage s'effectuant dans le sens axial, autrement dit selon un axe parallèle à l'axe de la bague de serrage 2.  The clamping means 6, 7 will therefore tighten the battery lug 1, coming into contact with the radial extensions thereof, the clamping being effected in the axial direction, in other words along an axis parallel to the axis. of the clamping ring 2.
Les forces appliquées sur la partie supérieure des extensions radiales 4 , 5 seront par conséquent les mêmes que celles appliquées sur la partie inférieure desdites extensions radiales 4 , 5.  The forces applied on the upper part of the radial extensions 4, 5 will therefore be the same as those applied to the lower part of said radial extensions 4, 5.
Le serrage se fait, plus particulièrement, par l'action de moyens de serrage 8 conçus aptes à rapprocher lesdits moyens d' enserrement 6 , 7 , et donc à rapprocher les deux extensions radiales 4 , 5 ce qui , par conséquent , entraine une diminution de la largeur de la fente 3 pour que la bague de serrage 2 vienne, par déformation, serrer efficacement la borne de la batterie sur laquelle elle est placée. The clamping is done, more particularly, by the action of clamping means 8 designed adapted to bring said clamping means 6, 7, and thus to bring the two extensions radial 4, 5 which, consequently, causes a decrease in the width of the slot 3 so that the clamping ring 2 comes, by deformation, effectively tighten the terminal of the battery on which it is placed.
Tout préférentiellement , et en référence aux figures 1, Most preferably, and with reference to FIGS.
2 , lesdits moyens de serrage 8 consistent en une vis 80 apte à réunir les deux moyens d' enserrement 6 , 7 qui comportent alors , chacun, un trou respectivement 63, 73. 2, said clamping means 8 consist of a screw 80 adapted to join the two gripping means 6, 7 which then each comprise a hole 63, 73 respectively.
Ainsi, et comme on le déduit de la figure 1 notamment, ladite vis 80 passe par le trou 63 du premier moyen d' enserrement 6, puis dans le cylindre fendu entre les extensions radiales 4 , 5 , ce dernier présentant alors un usinage 9 de forme cylindrique adapté au passage de ladite vis 80 et d'un diamètre suffisant à permettre le rapprochement des extensions radiales 4 et 5 et, enfin, par le trou 73 du second moyen d' enserrement 7, celui-ci étant taraudé.  Thus, and as can be deduced from FIG. 1 in particular, said screw 80 passes through the hole 63 of the first gripping means 6, then into the cylinder split between the radial extensions 4, 5, the latter then presenting a machining 9 of cylindrical shape adapted to the passage of said screw 80 and of a diameter sufficient to allow the approximation of the radial extensions 4 and 5 and, finally, through the hole 73 of the second clasping means 7, the latter being threaded.
Cela permet de rapprocher, par déformation, le diamètre fendu 3 formé par l'opération de sciage de la cosse de batterie 1. L'usinage 9 permettant le passage de la vis 80 et le taraudage au niveau du trou 73 du moyen d' enserrement 7 traversé en second par ladite vis 80 assurant un blocage de la vis en rotation et imperdable par ajout d'une déformation de l'extrémité de la vis 80.  This makes it possible to bring the split diameter 3 formed by the sawing operation of the battery lug 1 closer together by deformation. The machining 9 allows the passage of the screw 80 and the tapping at the hole 73 of the clamping means. 7 traversed secondly by said screw 80 ensuring locking of the screw in rotation and captive by adding a deformation of the end of the screw 80.
De manière avantageuse , et comme visible sur les figures , ces moyens d' enserrement 6 , 7 présentent une forme générale en « V » qui vient en contact tangent avec la surface extérieure cylindrique des extensions radiales 4 , 5 ce qui permet une réduction des frottements entre les moyens d' enserrement 6, 7 et lesdites extensions radiales 4, 5, diminuant ainsi les efforts à appliquer pour le serrage, et ce quel que soit l'angle formé par les deux branches du « V ».  Advantageously, and as visible in the figures, these clasping means 6, 7 have a general shape in "V" which comes into tangential contact with the cylindrical outer surface of the radial extensions 4, 5 which allows a reduction in friction between the clasping means 6, 7 and said radial extensions 4, 5, thus reducing the forces to be applied for the clamping, whatever the angle formed by the two branches of the "V".
En tout état de cause, les deux moyens d' enserrement 6, 7 peuvent venir en butée, en fonctions du couple de serrage, pour éviter une déformation permanente de la cosse de batterie 1 de l'invention. Bien évidemment, la solution cylindrique est considérée comme une solution optimale à l'obtention du résultat escompté. Toutefois, cette solution n'est pas limitative et il est envisageable par exemple d'utiliser deux extensions radiales de section carrée et fendues selon une diagonale, qui permettent un contact glissant avec les mors des mâchoires qui sont d'angle équivalent à celui des extensions . In any event, the two clasping means 6, 7 can abut, as a function of the tightening torque, to avoid permanent deformation of the battery lug 1 of the invention. Of course, the cylindrical solution is considered as an optimal solution to obtain the expected result. However, this solution is not limiting and it is possible for example to use two radial extensions of square section and diagonally split, which allow a sliding contact with the jaws of the jaws which are at an angle equivalent to that of the extensions. .
