Abstract

Connection device having male/female end pieces of round shape, which enables contact resistance to be reduced and thus heating of the electrical circuit to be prevented for disconnectable connectors, irrespective of their frequency of operation (stressing). It is composed of a male end piece 1, including a sliding tube 3, and a female end piece 2 also equipped with a sliding tube 3. The device according to the invention is particularly intended for measurement-circuit and safety connections.

Description

DESCRIPTION
La présente invention concerne les dispositifs de connexion composés d'embouts de cables mâles/femelles de forme ronde, qui permettent d'accoupler, ou de séparer rapidement et à volonté les extrémités de deux cables électriques.DESCRIPTION
The present invention relates to connection devices composed of end caps of male / female cables of round shape, which make it possible to quickly couple and separate the ends of two electric cables at will.

Sur les dispositifs connus de ce genre, la fixation du cable sur les embouts est généralement réalisée par soudure, par sertissage, ou à l'aide d'une vis de serrage. Ces procédes sont souvent mal aisés et détériorent le câble dans la plupart des cas. On known devices of this kind, the fixing of the cable on the end pieces is generally carried out by welding, by crimping, or using a clamping screw. These procedures are often difficult and deteriorate the cable in most cases.

De surcroit, la partie connecteur de ces embouts présente un jeu d'emmanchement nécessaire (si faible soit-il) auquel on remédie en pratiquant des fentes longitudinales, afin de permettre soit d'écarter les branches des embouts males, soit de resserrer les mâchoires des embouts femelles, de manière à obtenir un point de contact (par branche ou mâchoire) possèdant une faible pression; ce qui dans les deux cas à pour effet de modifier la texture du métal employé, qui peu à peu reprend sa forme primitive après un temps d'utilisation.In addition, the connector part of these end pieces has a necessary fitting clearance (however small) which is remedied by practicing longitudinal slots, in order to allow either to separate the branches from the male end pieces, or to tighten the jaws female end pieces, so as to obtain a contact point (by branch or jaw) having low pressure; which in both cases has the effect of modifying the texture of the metal used, which gradually returns to its original form after a period of use.

Suivant d'autres procédés, les embouts femelles possèdent un ressort auxiliaire inéfficace ou encombrant, ne permettant pas la réalisation d'ensembles de petite dimension. Autant d'inconvénients qui ont pour effet d'augmenter la résistance de contact, favorisant ainsi l'échauffement des circuits, ou d'occuper une place importante. According to other methods, the female end pieces have an ineffective or bulky auxiliary spring, not allowing the production of small assemblies. As many disadvantages which have the effect of increasing the contact resistance, thus favoring the heating of the circuits, or occupying an important place.

Les embouts suivant l'invention, permettent d'éviter ces inconvénients, car il est possible d'obtenir une liaison parfaite avec le conducteur, par pression périphérique sur celui-ci, aisément, et s'en craindre sa détérioration. The ferrules according to the invention make it possible to avoid these drawbacks, because it is possible to obtain a perfect connection with the conductor, by peripheral pressure thereon, easily, and fear its deterioration.

En effet, la partie servant à la fixation du conducteur est en forme de pince (fig.2) dont l'extérieur des mors 4 possède une rampe conique 8, qui est ceinturée par un tube coulissant 3 dont l'intérieur est pourvu d'une rampe conique inverse 9, qui a pour effet par un mouvement de translation (fig.3) imprimé à l'aide d'un outil approprié de resserrer les mors 4 autour du cable 5 qui a été préalablement introduit dans la pince. In fact, the part used for fixing the conductor is in the form of a clamp (fig. 2), the outside of the jaws 4 of which has a conical ramp 8, which is surrounded by a sliding tube 3, the inside of which is provided with a reverse conical ramp 9, which has the effect by a translational movement (fig. 3) printed using an appropriate tool to tighten the jaws 4 around the cable 5 which has been previously introduced into the clamp.

D'autre part, les points de contact de la partie connecteur sur les branches e de l'embout mâle (fig.2 & ), ou sur les machoires 12 de l'embout femelle (fig.4 & ) se trouvent doublés et offrent une forte pression sans avoir à contrarier la texture du métal par une déformation nécessaire à l'obtention d'une pression précaire. On the other hand, the contact points of the connector part on the branches e of the male end (fig. 2 &), or on the jaws 12 of the female end (fig. 4 &) are doubled and offer high pressure without having to counteract the texture of the metal by a deformation necessary to obtain precarious pressure.

Selon une réalisation de l'invention (fig.2 & ), le côté connecteur de l'embout femelle 2 est une alvéole cylindrique et, l'embout mâle l une broche fendue en croix sur une partie de sa longueur, afin d'obtenir quatre branches 6, et qui comporte un moyen de doubler les points de contact et d'en assurer la pression. According to one embodiment of the invention (fig. 2 &), the connector side of the female end piece 2 is a cylindrical cell and, the male end piece a pin split crosswise over part of its length, in order to obtain four branches 6, and which includes a means of doubling the contact points and ensuring the pressure.

Pour parvenir à ce résultat, la broche fendue de l'embout male 1 est de forme conique dont le diamètre en "e" est légèrement plus grand que le diamètre "f" de l'embout cylindrique femelle 2 correspondant, ce qui permet en association avec les fentes réalisées, et dans la limite de leur largeur, d'obtenir une contrainte permanente sur les branches 6 qui se resserrent avec réticence lors de leur introduction dans l'embout femelle. To achieve this result, the split pin of the male end 1 is conical in shape, the diameter of "e" is slightly larger than the diameter "f" of the corresponding female cylindrical end 2, which allows in association with the slots made, and within the limit of their width, to obtain a permanent constraint on the branches 6 which tighten reluctantly during their introduction into the female endpiece.

En complément, l'arc de cercle, engendré par chaque branche de l'embout male possédant une flèche plus courte que celle de l'embout femelle, pour une corde identique, et ce en raison de la différence de diamètre, ce sont par construction géométrique, les deux extrémités de l'arc de chaque branche qui produisent les pointes de contact. In addition, the arc of a circle, generated by each branch of the male end having a shorter arrow than that of the female end, for an identical rope, and this because of the difference in diameter, these are by construction geometric, the two ends of the arc of each branch which produce the contact points.

Selon une autre réalisation de l'invention (fig.4 & ) l'embout mâle 10 est une simple broche cylindrique, et c'est l'embout femelle 11 qui, usiné suivant une forme appropriée, est ensuite fendu en croix de manière à obtenir une pince, dont l'alésage "h" d'entrée est légèrement plus petit que le diamètre "g" de la broche male 10 correspondante. According to another embodiment of the invention (fig. 4 &) the male end piece 10 is a simple cylindrical pin, and it is the female end piece 11 which, machined in an appropriate shape, is then split in a cross so as to obtain pliers, the inlet bore "h" of which is slightly smaller than the diameter "g" of the corresponding male pin 10.

Les dessins annexés, illustrent à titre d'exemple la réalisation d'embouts conformes à la présente invention. The accompanying drawings illustrate by way of example the production of end pieces in accordance with the present invention.
