Abstract
Description
La présente invention se rapporte à une cosse pré-vue à l'extrémité d'unThe present invention relates to a pre-view pod at the end of a
câble électrique et destinée à être engagée sur une tige filetée solidaire d'une borne, par exemple la borne + ou la borne - d'une batterie, ou plus electrical cable and intended to be engaged on a threaded rod integral with a terminal, for example the + terminal or the terminal - of a battery, or more
simplement à une masse.simply to a mass.
La cosse étant traversée par la tige filetée, elle est serrée par un écrou. Si l'écrou est parfaitement serré, la liaison électrique est convenablement réalisée. The lug being crossed by the threaded rod, it is tightened by a nut. If the nut is perfectly tightened, the electrical connection is properly made.
Si, par contre l'écrou est manquant ou non bloqué, il y a une défaillance du circuit électrique et celle-ci est, le plus souvent, constatée en aval d'un test électrique. Un tel défaut peut entraîner de nombreuses perturbations et mettre en cause la sécurité. If, against the nut is missing or not blocked, there is a failure of the electrical circuit and it is, in most cases, found downstream of an electrical test. Such a fault can cause many disturbances and jeopardize the security.
L'un des buts de l'invention est de réaliser une cosse qui permet immédiatement de détecter un mauvais vis-sage de l'écrou ou l'absence de ce dernier. One of the aims of the invention is to provide a lug that immediately makes it possible to detect a bad vis-wise of the nut or the absence of the latter.
La cosse, selon l'invention, est du type réalisé à partir d'un corps d'un matériau bon conducteur de l'électricité présentant un anneau destiné à être engagé sur une tige filetée et serré par un écrou vissé sur ladite tige filetée et prolongé radialement par une partie destinée à recevoir et à assujettir un conducteur électrique, ladite cosse étant caractérisée en ce qu'elle comporte, sur la surface interne de son anneau, une bague en matière souple, isolante et élastique dont les extrémités dépassent les extrémités de l'anneau. The pod, according to the invention, is of the type made from a body of a good electrically conductive material having a ring intended to be engaged on a threaded rod and tightened by a nut screwed onto said threaded rod and radially extended by a portion for receiving and securing an electrical conductor, said terminal being characterized in that it comprises, on the inner surface of its ring, a ring of flexible material, insulating and elastic whose ends exceed the ends of the ring.
Ainsi, si l'écrou n'est pas convenablement serré, aucune liaison électrique ne pourra se faire. Thus, if the nut is not properly tightened, no electrical connection can be made.
Afin de faciliter l'engagement de l'anneau sur la 5 tige filetée, la bague présente une partie médiane cylin- drique raccordée aux petites bases de deux parties tronco- niques. In order to facilitate engagement of the ring on the threaded shank, the ring has a cylindrical middle portion connected to the small bases of two truncated portions.
Enfin, suivant une variante de réalisation, la 10 cosse comporte une seconde bague sur la face externe de l'anneau dont les extrémités dépassent les extrémités dudit anneau. Finally, according to an alternative embodiment, the lug comprises a second ring on the outer face of the ring whose ends protrude from the ends of said ring.
L'invention va maintenant être décrite avec plus 15 de détails en se référant à des modes de réalisation parti- culiers donnés à titre d'exemple seulement et représentés aux dessins annexés. The invention will now be described in more detail with reference to particular embodiments given by way of example only and shown in the accompanying drawings.
Figure 1 est une vue en plan d'une cosse, selon 20 l'invention. Figure 1 is a plan view of a terminal according to the invention.
Figure 2 est une vue en coupe suivant la ligne 2-2 de la figure 1. Figure 2 is a sectional view along the line 2-2 of Figure 1.
Figure 3 montre en élévation la cosse représentée partiellement en coupe, le montage de la cosse sur une tige filetée. Figure 3 shows in elevation the lug shown partially in section, the mounting of the lug on a threaded rod.
Figure 4 est une vue en plan d'une variante de 30 réalisation de la cosse, selon l'invention. Figure 4 is a plan view of an alternative embodiment of the terminal according to the invention.
Figure 5 est une vue en coupe suivant la ligne 5-5 de la figure 4. Figure 5 is a sectional view along the line 5-5 of Figure 4.
Figure 6 montre en élévation la cosse posée, celle-ci étant représentée en coupe. Figure 6 shows in elevation the lug posed, the latter being shown in section.
La cosse représentée aux figures 1 à 3 est formée à partir d'un corps bon conducteur de l'électricité et conformée pour présenter un anneau 1 prolongé radialement par une partie 2 présentant, d'une part, des pattes de sertissage 3 d'une extrémité dénudée d'un conducteur 5 logé dans une gaine 6 et, d'autre part, des pattes de sertissage dudit conducteur 5. The lug shown in FIGS. 1 to 3 is formed from a body that is good conductor of electricity and shaped to present a ring 1 radially extended by a portion 2 having, on the one hand, crimping lugs 3 of a denuded end of a conductor 5 housed in a sheath 6 and, secondly, crimping tabs of said conductor 5.
Conformément à l'invention, sur la surface intérieure 13 de l'anneau 1 est fixée ou moulée une bague souple, élastique, en matière isolante 8. According to the invention, on the inner surface 13 of the ring 1 is fixed or molded a flexible, resilient ring of insulating material 8.
La bague 8 présente une partie cylindrique 9 correspondant sensiblement au diamètre de la tige filetée 10 sur laquelle elle doit être montée, cette partie cylindrique étant, d'un côté, raccordée à la petite base d'une partie tronconique 11 et, de l'autre côté, à la petite base d'une seconde partie tronconique 12. The ring 8 has a cylindrical portion 9 substantially corresponding to the diameter of the threaded rod 10 on which it must be mounted, this cylindrical portion being, on one side, connected to the small base of a frustoconical portion 11 and, of the on the other hand, at the small base of a second frustoconical part 12.
La bague 8 a une hauteur légèrement supérieure à celle de l'anneau 1 de la cosse de manière qu'elle dépasse 25 légèrement les deux extrémités de l'anneau 1. The ring 8 has a height slightly greater than that of the ring 1 of the pod so that it slightly exceeds both ends of the ring 1.
A la figure 3, on a représenté un contact qui peut être l'une des bornes d'une batterie, une prise de masse ou autre, ce contact présentant une borne constituée par la tige filetée 10, celle-ci étant destinée à recevoir un écrou 14. FIG. 3 shows a contact which may be one of the terminals of a battery, a grounding plug or the like, this contact having a terminal constituted by the threaded rod 10, the latter being intended to receive a nut 14.
Lorsque la cosse est engagée par son anneau 1 sur la tige filetée 10, elle est isolée grâce à la bague 8. Pour réaliser la liaison électrique, il faut impérativement que l'écrou 14 soit parfaitement serré de manière à compri- mer les extrémités de la bague. When the lug is engaged by its ring 1 on the threaded rod 10, it is isolated thanks to the ring 8. To make the electrical connection, it is imperative that the nut 14 is perfectly tightened so as to compress the ends of the the ring.
On remarquera que l'anneau 1 peut être engagé sur la tige fileté 10 dans un sens ou tourné de 180 . It will be noted that the ring 1 can be engaged on the threaded rod 10 in one direction or rotated 180.
Aux figures 4, 5 et 6, on a représenté une va-riante de réalisation. Sur ces figures, on a reporté les références utilisées sur les figures précédentes pour désigner les éléments correspondants, mais affectées de la lettre "a". In Figures 4, 5 and 6, there is shown a va-riante embodiment. In these figures, the references used in the preceding figures have been used to designate the corresponding elements, but assigned the letter "a".
Dans ce mode de réalisation l'anneau la est solidaire d'une douille 16 dans laquelle est engagée et soudée l'extrémité dénudée du conducteur 5a. In this embodiment the ring is integral with a bushing 16 in which is engaged and welded the stripped end of the conductor 5a.
En plus de la bague 8a, il est prévu une seconde bague 15 fixée ou surmoulée sur la face externe de l'anneau la, les extrémités de ladite bague 15 dépassant les extrémités de l'anneau la pour s'étendre au même niveaux que les extrémités de la bague 8a. In addition to the ring 8a, there is provided a second ring 15 fixed or overmolded on the outer face of the ring la, the ends of said ring 15 protruding from the ends of the ring la to extend to the same levels as the ends of the ring 8a.
Comme dans le mode de réalisation précédent, on conçoit que la liaison électrique ne pourra être réalisée que si l'anneau la est parfaitement serré par l'écrou 14a, les extrémités des bagues 8a et 15 étant comprimées par le serrage de l'écrou. As in the previous embodiment, it is conceivable that the electrical connection can be achieved only if the ring is perfectly tightened by the nut 14a, the ends of the rings 8a and 15 being compressed by the tightening of the nut.
La bague 15 permet d'assurer l'étanchéité autour de l'anneau la. The ring 15 makes it possible to seal around the ring 1a.
Bien entendu, l'invention n'est pas limitée aux modes de réalisation qui viennent d'être décrits et repré- sentés. On pourra y apporter de nombreuses modifications de 5 détail sans sortir pour cela du cadre de l'invention. Of course, the invention is not limited to the embodiments which have just been described and shown. Many modifications can be made in detail without departing from the scope of the invention.
