Abstract
Description
La présente invention concerne le domaine des équipements électroniques ou électriques, en particulier des fiches et câbles, et a pour objet un dispositif d'assujettissement d'un câble à une fiche.The present invention relates to the field of electronic or electrical equipment, in particular plugs and cables, and relates to a device for securing a cable to a plug.
Actuellement, la fixation des câbles électriques ou de liaison d'équipements électroniques aux fiches de branchement correspondantes est généralement effectuée au moyen d'un écrou serre- câble coopérant avec des éléments élastiquement déformables des fiches pour serrer l'extrémité du câble pénétrant dans ces dernières. Il existe également des dispositifs de fixation du câble aux fiches par surmoulage simultané des extrémités du câble et de la fiche.Currently, the fixing of electric cables or electronic equipment connecting cables to the corresponding connection plugs is generally carried out by means of a cable clamp nut cooperating with elastically deformable elements of the plugs to clamp the end of the cable penetrating into the latter. . There are also devices for fixing the cable to the plugs by simultaneous overmolding of the ends of the cable and of the plug.
Ces moyens de liaison connus ne permettent cependant pas d'assurer une bonne tenue de l'extrémité des câbles dans les fiches tant en traction qu'en compression ou en torsion, de sorte que des détériorations des soudures ou des sertissages de branchement des contacts ou un arrachement des connexions par manipulation brusque, en particulier par traction sur les câbles, sont quasiment inévitables.These known connecting means do not however make it possible to ensure good resistance of the end of the cables in the plugs, both in tension, in compression or in torsion, so that deterioration of the welds or crimping of connection of the contacts or tearing of the connections by rough handling, in particular by pulling on the cables, is almost inevitable.
La présente invention a pour but de pallier ces inconvénients.The present invention aims to overcome these drawbacks.
Elle a, en effet, pour objet un dispositif d'assujettissement d'un câble à une fiche, sous la forme d'ergots et d'un capuchon, caractérisé en ce que les ergots sont disposés en croix sur la partie intérieure dans les parties de sortie de câble de la fiche, en ce que des extrémités déformables sont prévues aux parties de sortie de câble présentant une surface extérieure tronconique et en ce que le capuchon sert à assembler les parties de sortie de câble et à serrer les extrémités des parties.It has, in effect, a device for securing a cable to a plug, in the form of lugs and a cap, characterized in that the lugs are arranged in a cross on the inner part in the parts cable outlet of the plug, in that deformable ends are provided at the cable outlet parts having a frustoconical outer surface and in that the cap is used to assemble the cable outlet parts and to clamp the ends of the parts.
L'invention sera mieux comprise grâce à la description ci-après, qui se rapporte à un mode de réalisation préféré, donné à titre d'exemple non limitatif, et expliqué avec référence au dessin schématique annexé, dans lequel:
- la figure 1 est une vue éclatée en plan et partiellement en coupe, du dispositif conforme à l'invention;
- la figure 2 est une vue analogue à celle de la figure 1 d'une variante de réalisation de l'invention, et la figure 3 représente, en plan, une carotte de demi-coquilles de réduction.
- Figure 1 is an exploded plan view and partially in section, of the device according to the invention;
- Figure 2 is a view similar to that of Figure 1 of an alternative embodiment of the invention, and Figure 3 shows, in plan, a core of reduction half-shells.
Dans les figures 1 et 2 du dessin annexé, la fiche 3 représentée est une fiche péritélévision connue sous la dénomination normalisée SCART.In FIGS. 1 and 2 of the appended drawing, the
Conformément à l'invention, et comme le montre plus particulièrement à titre d'exemple, la figure 1 du dessin annexé, le dispositif d'assujettissement d'un câble à une fiche, sous la forme d'ergots 1 et d'un capuchon 4, est caractérisé en ce que les ergots 1 sont disposés en croix sur la partie intérieure dans les parties 2 de sortie de câble de la fiche 3. Sur les parties 2 sont prévues des extrémités déformables 2' qui présentent une surface extérieure tronconique 2" et le capuchon 4 sert à assembler les parties 2 de sortie de câble et à serrer les extrémités 2' desdites parties 2.According to the invention, and as shown more particularly by way of example, Figure 1 of the accompanying drawing, the device for securing a cable to a plug, in the form of lugs 1 and a
Les ergots en croix 1 sont destinés à pénétrer dans la gaine du câble de manière à l'immobiliser, en particulier en rotation, après montage du capuchon 4. Cette immobilisation est cependant également effectuée dans le sens d'une traction ou d'une pression sur le câble. Les extrémités 2' des parties 2 sont déformées lors de la mise en place du capuchon 4 dans le sens d'une pénétration de leur bord dans la gaine du câble, de sorte qu'une translation de ce dernier est totalement empêchée.The cross lugs 1 are intended to penetrate the sheath of the cable so as to immobilize it, in particular in rotation, after mounting of the
Le capuchon 4 présente avantageusement une forme tronconique et est muni, d'une part, le long d'une génératrice extérieure d'un repère 10 correspondant à une rainure longitudinale interne 11 destinée à coopérer avec une nervure 12 de l'une des parties 2 de sortie de câble, et, d'autre part, près de son plus grand diamètre, d'un renflement annulaire interne 13 coopérant en position d'assemblage du capuchon 4 avec une gorge 14 de la surface externe des parties 2 proche du corps de la fiche 3. Le repère 10 permet de positionner rapidement le capuchon 4 en vue de son emboîtement guidé sur la nervure 12 au moyen de la rainure 11 et le renflement annulaire interne 13 .assure, en coopération avec la gorge 14, le blocage en position du capuchon 4. En outre, la nervure 12 et la rainure 11 empêchent une rotation du capuchon.The
La figure 2 représente une variante de réalisation de l'invention, dans laquelle le dispositif est complété, en outre, par deux demi-coquilles de réduction présentant un contour extérieur épousant le contour intérieur des parties 2 de la sortie de câble et munies, d'une part, sur leur face externe, de logements 6 de forme et de dimension correspondantes à celles des ergots 1 des parties 2, et, d'autre part, sur leur face interne, d'ergots en croix 7, analogues aux ergots 1, ainsi que, à leur extrémité tournée vers l'extérieur de la fiche 3, de segments tronconiques déformables 8.FIG. 2 represents an alternative embodiment of the invention, in which the device is completed, in addition, by two reduction half-shells having an external contour matching the internal contour of the
Grâce à un tel mode de réalisation, il est possible d'adapter le serrage d'un câble à son diamètre sans prévision d'une réalisation spéciale de fiche en fonction dudit diamètre. Le dispositif conforme à l'invention permet ainsi, contrairement aux dispositifs de fixation existants, l'utilisation d'une fiche unique pour un grand nombre de diamètres de câbles, tout en assurant dans tous les cas un assujettissement parfait de ces derniers.Thanks to such an embodiment, it is possible to adapt the tightening of a cable to its diameter without providing for a special production of plug as a function of said diameter. The device according to the invention thus allows, unlike existing fixing devices, the use of a single plug for a large number of cable diameters, while ensuring in all cases a perfect securing of the latter.
Selon une autre caractéristique de l'invention, le dispositif comporte plusieurs paires de demi-coquilles 5 pouvant être montées dans les parties 2 de la sortie de câble de la fiche 3, ces demi-coquilles présentant des diamètres intérieurs dégressifs et étant avantageusement montées de manière arrachable pour le conditionnement de stockage et de vente sur une carotte 9 provenant du moulage en commun avec lesdites demi-coquilles 5 (figure 3).According to another characteristic of the invention, the device comprises several pairs of half-shells 5 which can be mounted in the
Grâce à l'invention, il est possible de réaliser une liaison fable entre un câble et une fiche de connexion électrique ou électronique quel que soit le diamère du câble utilisé. Ainsi, la fabrication d'un type de fiche donnee pour un diametre- donne devient inutile, et le prix de revient de telles fiches peut être notablement réduit, ainsi que les stocks nécessaires.Thanks to the invention, it is possible to make a reliable connection between a cable and an electrical or electronic connection plug regardless of the diameter of the cable used. So the fabrica tion of a given type of plug for a given diameter becomes unnecessary, and the cost price of such plugs can be significantly reduced, as well as the stocks required.
