Description

L'invention concerne un système de connexion rapide pour raccorder des câbles électriques sur une batterie.The invention relates to a quick connection system for connecting electric cables to a battery.

Dans le domaine des connecteurs de câbles électriques sur des cosses de batterie il est connu d'employer divers embouts emboîtables permettant un raccordement rapide sur la batterie.In the field of electrical cable connectors on battery terminals it is known to use various interlocking tips for quick connection to the battery.

Il a par exemple été proposé dans le brevet FR 2 745 123 de la demanderesse un connecteur pour borne de batterie comportant un système de clippage évitant le démontage et permettant des gains de productivité sur les chaînes de montage automobiles.For example, it has been proposed in the patent FR 2,745,123 Applicant a connector for battery terminal having a clipping system avoiding disassembly and allowing productivity gains on automotive assembly lines.

Il a aussi été proposé dans le document FR 2 776 424 un système de connexion rapide permettant un raccordement des câbles électriques sans qu'il soit nécessaire d'employer un outillage quelconque.It was also proposed in the document FR 2 776 424 a quick connection system allowing a connection of the electric cables without the need to use any tools.

Ce système de connexion rapide permet de verrouiller la cosse par emboîtement sur la borne de la batterie dans un boîtier d'isolation la protégeant de l'atmosphère environnante et garantissant un contact étroit entre la cosse et la borne.This quick connection system makes it possible to lock the terminal by interlocking on the terminal of the battery in an insulation box protecting it from the surrounding atmosphere and guaranteeing a close contact between the terminal and the terminal.

Ce contact entre la cosse et la borne de la batterie, dans les raccordements traditionnels comportant un serrage au moyen d'un collier bloqué par vissage, a généralement tendance à se dégrader dans le temps, ce qui a pour conséquence une perte de performance de la batterie et parfois une oxydation des cosses. Les vibrations engendrées par le véhicule pouvant également entraîner, avec le temps, un glissement de la connexion et des mauvais contacts.This contact between the terminal and the terminal of the battery, in the traditional connections having a tightening by means of a necklace blocked by screwing, generally tends to degrade in the time, which results in a loss of performance of the battery and sometimes an oxidation of the pods. The vibrations generated by the vehicle can also cause, over time, a slippage of the connection and bad contacts.

La solution proposée dans le brevet FR 2 776 424 permet de résoudre ces problèmes dans la mesure où le dispositif de connexion rapide est correctement ajusté sur les bornes, ce qui n'est malheureusement pas toujours le cas.The solution proposed in the patent FR 2 776 424 solves these problems because the quick connect device is correctly adjusted on the terminals, which is unfortunately not always the case.

En effet, en raison du manque de temps, de la difficulté d'accès ou de conditions de travail délicates il est fréquent que le système de connexion rapide soit mal emboîté, ce qui a pour conséquence la perte de la conduction dans les câbles et l'arrêt du moteur ou des décharges électriques intempestives entre la cosse et la borne ou encore, dans la plupart des cas, le glissement de la cosse autour de la borne et les mêmes problèmes que ceux fréquemment rencontrés dans les connecteurs traditionnels.Indeed, due to lack of time, difficulty of access or delicate working conditions it is common that the quick connection system is poorly fitted, which results in the loss of conduction in the cables and the motor shutdown or untimely electric shocks between the terminal and the terminal or, in most cases, slipping of the terminal around the terminal and the same problems as those frequently encountered in traditional connectors.

Il existe donc un problème à résoudre en relation avec le mauvais emboîtement de la connexion rapide sur la borne de la batterie.There is therefore a problem to be solved in connection with the bad fitting of the fast connection on the terminal of the battery.

Le document EP 1 498 987 décrit une connexion de batterie avec un système d'anti-verrouillage empêchant le verrouillage de la connexion si l'emboîtement n'est pas correctement réalisé. Pour cela le verrouillage n'est autorisé que si un levier est en contact avec la face supérieure de la borne.The document EP 1 498 987 describes a battery connection with an anti-lock system preventing locking of the connection if the nesting is not properly performed. For this, locking is only allowed if a lever is in contact with the upper face of the terminal.

Cependant les tolérances admises lors de la fabrication des bornes peuvent entraîner une mauvaise mise en place de la connexion.However tolerances allowed during the manufacture of the terminals can cause a bad establishment of the connection.

L'invention a donc pour objectif de résoudre cette difficulté et d'améliorer le système de connexion rapide existant en proposant un système anti-verrouillage empêchant un emboîtement incomplet de la cosse sur la borne. La présente invention propose une connexion de batterie avec système anti-verrouillage selon la revendication 1.The invention therefore aims to solve this problem and improve the existing quick connection system by providing an anti-locking system preventing incomplete engagement of the pod on the terminal. The present invention provides a battery connection with an anti-lock system according to claim 1.

Les avantages du dispositif d'anti-verrouillage pour une connexion de batterie selon l'invention sont multiples :

  • La vérification d'un emboîtement correct de la connexion est réalisée par rapport à la surface de la batterie et non par rapport à la borne. Ainsi il est possible de positionner correctement la connexion même si la borne présente des dimensions différentes dues notamment aux tolérances de fabrication admises.
  • Le dispositif n'autorise le verrouillage que si la cosse de la connexion est complètement enfoncée, ce qui supprime tous les problèmes connus de mauvaise fixation.
  • Si la connexion n'est pas correctement réalisée le levier de verrouillage reste levé, montrant à l'évidence à l'installateur que la connexion n'est pas effectuée.
  • Le mécanisme d'anti-verrouillage est de fonctionnement simple et fiable, ce qui garantit un maintien satisfaisant de la fonctionnalité dans le temps.
  • Le dispositif anti-verrouillage est intégré dans le mécanisme de verrouillage et correspond à un très faible surcoût de fabrication de la pièce de connexion, ce qui est économiquement avantageux.
The advantages of the anti-lock device for a battery connection according to the invention are multiple:
  • Verification of a correct interlocking of the connection is made with respect to the surface of the battery and not with respect to the terminal. Thus it is possible to correctly position the connection even if the terminal has different dimensions due in particular to acceptable manufacturing tolerances.
  • The device allows locking only if the terminal of the connection is fully depressed, which removes all known problems of poor attachment.
  • If the connection is not properly made the locking lever remains raised, obviously showing the installer that the connection is not made.
  • The anti-lock mechanism is simple and reliable operation, which ensures a satisfactory maintenance of the functionality over time.
  • The anti-lock device is integrated in the locking mechanism and corresponds to a very small additional manufacturing cost of the connection piece, which is economically advantageous.

D'autres caractéristiques et avantages de l'invention se dégageront de la description qui va suivre en regard des dessins annexés qui ne sont donnés qu'à titre d'exemples non limitatifs.Other features and advantages of the invention will become apparent from the description which follows with reference to the accompanying drawings which are given by way of non-limiting examples.

La figure 1 est une vue en perspective d'un dispositif de connexion rapide comportant un système anti-verrouillage selon l'invention.The figure 1 is a perspective view of a quick connect device comprising an anti-lock system according to the invention.

La figure 2 est une vue en coupe et de côté du mécanisme d'anti-verrouillage dans une situation d'emboîtement incomplet de la cosse sur la borne de la batterie.The figure 2 is a sectional and side view of the anti-lock mechanism in an incomplete nesting situation of the terminal on the terminal of the battery.

La figure 3 illustre en vue de côté et en coupe une situation dans laquelle la cosse est correctement emboîtée et le verrouillage est autorisé.The figure 3 illustrates in side and sectional view a situation in which the lug is properly nested and locking is allowed.

Comme le montre la figure 1, une connexion de batterie comportant le système anti-verrouillage selon l'invention est configurée de manière proche de celle décrite dans le brevet FR 2 776 424 de la demanderesse.As shown in figure 1 , a battery connection comprising the anti-lock system according to the invention is configured in a manner similar to that described in the patent FR 2 776 424 of the plaintiff.

Plus précisément la fixation de la cosse 1 sur la borne de la batterie s'effectue au moyen d'un ressort de serrage 2 situé sur le pourtour de la cosse.More specifically, the fixing of the lug 1 on the terminal of the battery is effected by means of a clamping spring 2 located on the periphery of the lug.

De manière connue la connexion de batterie comporte un boîtier 3 dans lequel les câbles électriques arrivent et sont connectés à la cosse, et un collier 4 en contact avec le plot de la batterie et recevant les câbles.In known manner the battery connection comprises a housing 3 in which the electric cables arrive and are connected to the lug, and a collar 4 in contact with the pad of the battery and receiving the cables.

Un levier 5 articulé en rotation entre une position verrouillée et une position déverrouillée permet le blocage de la connexion et le maintien ferme de la cosse sur la borne de la batterie.A lever 5 articulated in rotation between a locked position and an unlocked position allows the blocking of the connection and the firm hold of the terminal on the terminal of the battery.

Le dispositif anti-verrouillage empêche l'abaissement du levier 5 et donc le verrouillage de la connexion sur la borne de la batterie si l'emboîtement n'est pas correctement réalisé.The anti-lock device prevents the lowering of the lever 5 and thus the locking of the connection on the terminal of the battery if the nesting is not properly performed.

Plus précisément le système d'anti-verrouillage comporte un détecteur 6 mobile entre deux configurations qui correspondent à la position verrouillée et à la position déverrouillée de la connexion.More specifically, the anti-lock system comprises a detector 6 movable between two configurations that correspond to the locked position and the unlocked position of the connection.

Le détecteur 6 est directement relié à la cosse 1 destinée à être emboîtée sur la borne de la batterie.The detector 6 is directly connected to the lug 1 intended to be fitted on the terminal of the battery.

Plus précisément le détecteur 6 est une pièce métallique mobile en rotation autour d'un axe 7. Le détecteur est relié à un ressort de rappel 8 qui a pour effet de forcer la rotation du détecteur et donc d'empêcher le verrouillage de la connexion.More precisely, the detector 6 is a metal part rotatable about an axis 7. The detector is connected to a return spring 8 which has the purpose of effect of forcing the rotation of the detector and thus preventing the locking of the connection.

L'axe 7 de rotation du détecteur 6 est localisé sous le ressort de rappel 8 du détecteur de telle manière qu'en position de repos, c'est à dire lorsque la connexion n'est pas verrouillée sur la borne de la batterie, le détecteur 6 soit basculé dans une position inclinée en direction de la cosse 1 dans une configuration dénommée déverrouillée.The axis 7 of rotation of the detector 6 is located under the return spring 8 of the detector such that in the rest position, that is to say when the connection is not locked on the terminal of the battery, the detector 6 is tilted in an inclined position towards the lug 1 in a so-called unlocked configuration.

Lorsque la cosse est correctement emboîtée sur la borne de la batterie le détecteur 6 est basculé dans une position sensiblement verticale après rotation autour de l'axe 7. Cette configuration est dénommée verrouillée.When the lug is properly fitted to the battery terminal, the detector 6 is tilted to a substantially vertical position after rotation around the axis 7. This configuration is called locked.

Ainsi le passage entre les deux configurations du détecteur 6 s'effectue en une rotation autour de l'axe 7, le ressort de rappel ayant pour effet d'amener le détecteur en configuration déverrouillée si la cosse n'est pas complètement emboîtée sur la borne de la batterie.Thus the passage between the two configurations of the detector 6 is made in a rotation about the axis 7, the return spring having the effect of bringing the detector in unlocked configuration if the lug is not fully nested on the terminal drums.

Le détecteur tel que représenté sur les différentes figures présente une forme allongée et courbe avec une concavité orientée vers la borne de la batterie. La hauteur de cette pièce est très légèrement supérieure à la hauteur de la borne de la batterie.The detector as shown in the various figures has an elongate and curved shape with a concavity oriented towards the terminal of the battery. The height of this piece is slightly higher than the height of the battery terminal.

Les figures 2 et 3 illustrent les deux positions possibles pour le détecteur 6 dans les configurations verrouillée et déverrouillée.The Figures 2 and 3 illustrate the two possible positions for the detector 6 in the locked and unlocked configurations.

Sur la figure 2 la borne 9 de la batterie n'est pas correctement emboîtée dans la connexion, le ressort de rappel maintient le détecteur 6 dans une configuration déverrouillée, c'est à dire basculée en direction de la borne. Le levier 5, lors de son mouvement de rotation vers la position de verrouillage, c'est à dire dans le sens du déplacement indiqué par la flèche dans la figure 2, est bloqué par la partie supérieure du détecteur 6.On the figure 2 the terminal 9 of the battery is not correctly fitted into the connection, the return spring keeps the detector 6 in an unlocked configuration, that is, tilted toward the terminal. Lever 5, during its rotational movement towards the locking position, that is to say in the direction of displacement indicated by the arrow in the figure 2 , is blocked by the upper part of the detector 6.

Le levier 5, bloqué dans sa course, reste en position relevée, aisément visible par l'installateur.The lever 5, locked in its path, remains in the raised position, easily visible by the installer.

Le détecteur 6 comporte dans sa partie inférieure, c'est à dire celle proche du dessus de la batterie, un pied 10 positionné dessous l'axe 7 utile pour la rotation dudit détecteur.The detector 6 has in its lower part, that is to say the one near the top of the battery, a foot 10 positioned below the axis 7 useful for the rotation of said detector.

Tel que représenté sur les figures 2 et 3 le pied 10 du détecteur est positionné entre l'axe 7 et la borne 9 et entre l'axe 7 et le dessus de la batterie.As shown on the Figures 2 and 3 the foot 10 of the detector is positioned between the axis 7 and the terminal 9 and between the axis 7 and the top of the battery.

Lorsque la connexion est correctement emboîtée sur la borne, que la partie inférieure de la cosse arrive au contact du dessus de la batterie, comme cela est illustré sur la figure 3, le pied 10 du détecteur appuie sur le dessus de la batterie, ce qui a pour effet de repousser le détecteur et de le faire pivoter autour de l'axe 7.When the connection is properly nested on the terminal, that the lower part of the lug comes into contact with the top of the battery, as shown on the figure 3 , the foot 10 of the detector presses on the top of the battery, which has the effect of pushing the detector and rotate around the axis 7.

Ce mouvement de rotation a pour conséquence un basculement du détecteur vers une position sensiblement verticale qui dégage l'espace nécessaire pour que le levier 5 puisse se glisser entre le détecteur et la cosse et donc permettre le verrouillage de la connexion.This rotational movement results in a tilting of the detector to a substantially vertical position which releases the space required for the lever 5 to be able to slip between the detector and the lug and thus allow the connection to be locked.

Dans cette position verrouillée l'extrémité du levier 5 est dans une position sensiblement horizontale.In this locked position the end of the lever 5 is in a substantially horizontal position.

Dans la position verrouillée le levier 5 comprime le ressort de serrage 2 chargé de maintenir la cosse solidement fixée sur la borne de la batterie.In the locked position the lever 5 compresses the clamping spring 2 responsible for maintaining the lug securely attached to the terminal of the battery.

Ainsi selon l'invention le pied 10 du détecteur 6 est placé entre l'axe 7 de rotation et le bas de la borne 9 de la batterie de manière à provoquer un basculement dudit détecteur 6 vers la position verticale, c'est à dire vers la position verrouillée, lorsque la connexion est correctement emboîtée sur ladite borne 9 et que ledit pied 10 appuie sur le dessus de la batterie.Thus according to the invention the foot 10 of the detector 6 is placed between the axis 7 of rotation and the bottom of the terminal 9 of the battery so as to cause a switchover of said detector 6 to the vertical position, ie to the locked position, when the connection is properly nested on said terminal 9 and said foot 10 presses on the top of the battery.

Lorsque le levier 5 est relevé le passage entre la configuration verrouillée et la configuration déverrouillée du détecteur 6 s'effectue au moyen du ressort de rappel 8.When the lever 5 is raised the passage between the locked configuration and the unlocked configuration of the detector 6 is effected by means of the return spring 8.

De préférence le détecteur 6 et le système anti-verrouillage est positionné à l'opposé de l'arrivée des câbles, de manière à ce que l'opération de raccordement soit aisément réalisable pour la personne chargée du travail. Avantageusement selon l'invention le ressort de serrage 2 et le ressort de rappel 8 peuvent être conformés en une pièce unique agencée sur la cosse 1 de la connexion.Preferably the detector 6 and the anti-lock system is positioned opposite the arrival of the cables, so that the connection operation is easily achievable for the person in charge of the work. Advantageously according to the invention the clamping spring 2 and the return spring 8 can be shaped in a single piece arranged on the lug 1 of the connection.

Plusieurs variantes sont possibles pour le système anti-verrouillage porté par la connexion de batterie.Several variants are possible for the anti-lock system carried by the battery connection.

Le pied du détecteur et le détecteur lui-même peuvent être conformés de différentes manières sans sortir du cadre de l'invention.The foot of the detector and the detector itself can be shaped in different ways without departing from the scope of the invention.

Les différentes pièces employées dans la connexion sont avantageusement métalliques toutefois certains éléments pourraient être envisagés en plastique rigide sans sortir du cadre de l'invention.The various parts used in the connection are advantageously metallic, however some elements could be considered rigid plastic without departing from the scope of the invention.
