Description

Cet invention concerne une borne pour la con­nexion des câbles aux pôles positif et négatif des batteries électriques d'automobile. Actuellement les bornes pour la connexion des câbles aux pôles posi­tif et négatif des batteries électriques, par exem­ple des batteries d'automobile, se composent, cha­cune, d'un élément métallique,généralement de plomb, en forme de C présentant, d'un côté, une partie pour la connexion d'un câble électrique et, du côté ou­vert, deux ailettes à relier et rapprocher entre el­les au moyen d'une vis transversale de serrage quand la borne et accouplée et bloquée au pôle correspon­dant de la batterie.This invention relates to a terminal for connecting cables to the positive and negative poles of electric automobile batteries. Currently, the terminals for connecting cables to the positive and negative poles of electric batteries, for example automobile batteries, each consist of a metallic element, generally of lead, in the shape of a C having, on one side , a part for the connection of an electric cable and, on the open side, two fins to be connected and brought together by means of a transverse tightening screw when the terminal and coupled and locked at the corresponding pole of the battery.

Quand les bornes conditionnées de cette manière ont été connecté aux pôles de la batterie, elles re­sultent totalement exposées à l'atmosphère oxidante et/ou aux contacts accidentels. Pour cette raison il faut munir chaque borne, ou au moins celle connectée au pôle positif de la batterie, d'un capuchon pro­ tecteur contre l'oxidation et contre les contacts indésirables.When the terminals conditioned in this way have been connected to the poles of the battery, they result totally exposed to the oxidizing atmosphere and / or to accidental contacts. For this reason it is necessary to equip each terminal, or at least the one connected to the positive pole of the battery, with a pro cap. guard against oxidation and against unwanted contact.

En outre, le blocage des ces bornes aux pôles de la batterie au moyen des vis de serrage comporte leur déformation permanente et partant chaque borne tend à rester bloquée au pôle correspondant même quand la vis de serrage est desserrée. Par suite, il est assez difficile de détacher la borne pour l'en­tretien ou le remplacement de la batterie et en gé­néral il faut employer un outil pour desserrer et enlever la borne.In addition, the blocking of these terminals at the poles of the battery by means of the clamping screws involves their permanent deformation and hence each terminal tends to remain blocked at the corresponding pole even when the clamping screw is loosened. As a result, it is quite difficult to detach the terminal for maintenance or replacement of the battery and in general it is necessary to use a tool to loosen and remove the terminal.

De plus, chaque borne est assez souvent fixée à son câble au moyen des vis qui d'ailleurs n'excluent pas la possibilité d'un détachement accidentel du câble et partant la coupure du circuit alimenté par la batterie.In addition, each terminal is quite often fixed to its cable by means of screws which, moreover, do not exclude the possibility of accidental detachment of the cable and hence the interruption of the circuit supplied by the battery.

Par contre, la présente invention concerne une borne pour la connexion des câbles aux pôles des batteries électriques d'automobile conforme à la re­vendication 1).By cons, the present invention relates to a terminal for connecting cables to the poles of electric car batteries according to claim 1).

Le but de cette invention est d'éliminer les inconvénients et désavantages susmentionnés, son but principal étant ce de proposer une borne comprenant un corps doué d'une élasticité intrinsique apte à favoriser l'ouverture automatique de la borne et partant son détachement immédiat du pôle correspon­dant aussitôt que la vis de serrage est relâchée.The object of this invention is to eliminate the above-mentioned drawbacks and disadvantages, its main aim being that of proposing a terminal comprising a body endowed with an intrinsic elasticity capable of promoting the automatic opening of the terminal and thus its immediate detachment from the corresponding pole as soon as the clamping screw is released.

Un autre but de l'invention c'est de proposer une borne qui soit avantageusement autoprotectrice contre toute forme d'oxidation et de contact exté­rieur, en éliminant ainsi la nécessité d'y appliquer des éléments protécteurs ou des capuchons supplémen­taires.Another object of the invention is to propose a terminal which is advantageously self-protective against any form of oxidation and external contact, thereby eliminating the need to apply protective elements or additional caps thereto.

Un autre but encore de l'invention c'est de proposer une borne dans laquelle l'extrémité du câble électrique y connecté est enfoncée dans la partie métallique de la borne et recouverte et ar­rêtée par le revêtement protecteur de cette partie métallique de façon à assurer un fixage permanente du câble et à en empêcher le détachement accidentel.Yet another object of the invention is to provide a terminal in which the end of the electric cable connected thereto is inserted into the metal part of the terminal and covered and stopped by the protective coating of this metal part so as to ensure permanent fixing of the cable and preventing accidental detachment.

En tout cas, des détails plus précis de l'objet d'invention resulteront de la description ci-dessous donnée en référant au dessin ci-joint dans lequel:

  • la Fig. 1 montre une vue schématique d'une batterie avec câbles connectés aux pôles correspondants au moyen de bornes;
  • les Figures 2 et 3 montrent deux exemples de bornes avec et sans paroi protectrice supérieure pour le pôle positif et négatif de la batterie respecti­vement;
  • la Fig. 4 montre une section de la borne dont à la Fig. 2; et
  • la Fig. 5 montre la section d'une borne le long d'une ligne parallèle au plan.
In any case, more precise details of the object of invention will result from the description below given with reference to the attached drawing in which:
  • Fig. 1 shows a schematic view of a battery with cables connected to the corresponding poles by means of terminals;
  • Figures 2 and 3 show two examples of terminals with and without an upper protective wall for the positive and negative pole of the battery respectively;
  • Fig. 4 shows a section of the terminal of which in FIG. 2; and
  • Fig. 5 shows the section of a terminal along a line parallel to the plane.

La borne proposée se compose substantiellement d'un élément métallique 10, normalment de plomb, connecté électriquement à l'extrémité 11 d'au moins un câble électrique 12 enfoncé dans un corps protec­teur 13 moulé en matière plastique.The proposed terminal consists substantially of a metallic element 10 , normally of lead, electrically connected to the end 11 of at least one electrical cable 12 inserted in a protective body 13 molded in plastic.

L'élément métallique ou de plomb 10 se compose d'une bague ouverte 14 avec une partie 15 dans la­quelle on enfonce l'extrémité découverte 11 du câble électrique. Le corps de matière plastique 13 est pressé sur l'élément métallique 10 pour le bien ren­fermer et protéger, y comprise la partie 15 pour le logement du câble et aussi l'extrémité de ce der­nier, tandis que la surface intérieure de la bague ouverte 14 reste découverte.The metallic or lead element 10 consists of an open ring 14 with a part 15 in which the exposed end 11 of the electric cable is inserted. The plastic body 13 is pressed on the metal element 10 to enclose and protect it, including the part 15 for housing the cable and also the end of the latter, while the inner surface of the open ring 14 remains uncovered.

Du côté ouvert de la bague 14 le corps en ma­tière plastique 13 présente en outre deux ailettes 16 munies de trous transversaux 16ʹ pour le logement d'une vis de serrage 17 destinée à rapprocher les deux ailettes et à resserrer la bague ouverte 14 quand la borne est appliquée à un pôle 18 de la bat­terie 19.On the open side of the ring 14, the plastic body 13 also has two fins 16 provided with transverse holes 16ʹ for housing a clamping screw 17 intended to bring the two fins together and to tighten the open ring 14 when the terminal is applied to a pole 18 of the battery 19 .

Le corps protecteur de matière plastique 13 donne à la borne un haut degré l'élasticité pour en consentir l'ouverture automatique et donc le déta­chement de la bague du pôle de la batterie et le dé­gagement immédiat de la borne aussitôt que la vis de serrage a été relâchée, même quand elle avait été bloquée dès longtemps.The protective plastic body 13 gives the terminal a high degree of elasticity to allow automatic opening and therefore detachment of the ring from the battery pole and immediate release of the terminal as soon as the tightening screw has was released, even when it had been blocked for a long time.

Enfin, il faut remarquer qu'au moins la borne destinée à s'accoupler au pôle positif de la batte­rie pourra présenter, dans sa partie supérieure, une paroi 20 moulée avec le corps protecteur 13 et de­stinée à recouvrir et renfermer l'ouverture délimi­tée par la bague ouverte 14 et protéger de cette fa­çon le pôle de la batterie et aussi la bague 14 con­tre l'oxidation et contre tout contact extérieur.Finally, it should be noted that at least the terminal intended to couple to the positive pole of the battery may have, in its upper part, a wall 20 molded with the protective body 13 and intended to cover and enclose the opening delimited by the open ring 14 and in this way protect the pole of the battery and also the ring 14 against oxidation and against any external contact.
