Description

La présente invention concerne d'une manière générale un dispositif pour la distribution d'accessoires de câblage destinés à l'équipement de câbles électriques notamment de câbles à conducteur multibrins revêtu d'une gaine isolante.The present invention relates generally to a device for the distribution of wiring accessories intended for the equipment of electric cables in particular of cables with multi-strand conductor coated with an insulating sheath.

Ces accessoires de câblage peuvent être des cosses, comportant, spécifiquement, pour la connexion à établir, une oreille ou un doigt, aussi bien que des embouts à manchon isolant.These wiring accessories may be lugs, comprising, specifically, for the connection to be established, an ear or a finger, as well as insulating sleeve ends.

Bien entendu, la pose de ces accessoires de câblage sur l'extrémité dénudée du câble conducteur peut être exécutée à la main à l'aide d'un outillage traditionnel (dénude fil et pince à sertir). Toutefois, cette méthode trop coûteuse en temps et en personnel ne convient pas à l'exécution de câblages à cadence élevées.Of course, the installation of these wiring accessories on the stripped end of the conductor cable can be carried out by hand using traditional tools (wire stripper and crimping pliers). However, this method, which is too costly in terms of time and personnel, is not suitable for performing high-speed cabling.

D'autre part, lorsque les accessoires en cause sont des embouts de câblage, on sait que ceux-ci comportent un élément métallique tubulaire et un manchon isolant surmoulant une extrémité de l'élément tubulaire. Pour câbler des conducteurs dont la section varie par exemple entre 0,5 mm² et 2,5 mm², on utilise usuellement des embouts dont le diamètre de l'élément tubulaire varie entre 1,4 mm et respectivement 2,5 mm et dont le diamètre du manchon isolant varie entre 3 mm et respectivement 4,7 mm. Il serait souhaitable de pouvoir distribuer des séries d'embouts de diamètres différents avec un dispositif unique, requérant peu ou pas de modification.On the other hand, when the accessories in question are cable end caps, it is known that these include a tubular metal element and an insulating sleeve overmolding one end of the tubular element. To wire conductors whose cross section varies for example between 0.5 mm² and 2.5 mm², one usually uses ferrules whose diameter of the tubular element varies between 1.4 mm and 2.5 mm respectively and whose diameter of the insulating sleeve varies between 3 mm and 4.7 mm respectively. It would be desirable to be able to distribute series of tips of different diameters with a single device, requiring little or no modification.

Le brevet FR-2 642 233 décrit un dispositif distributeur et sertisseur d'embouts comprenant des roues dentées et entraînant une certaine complexité de réalisation.Patent FR-2 642 233 describes a device for distributing and crimping end pieces comprising toothed wheels and giving rise to a certain complexity of production.

L'invention a pour but de simplifier la distribution d'accessoires de câblage.The invention aims to simplify the distribution of wiring accessories.

Elle propose, d'une façon générale, un dispositif pour la distribution d'accessoires de câblage, destinés à l'équipement de câbles électriques, et reliés les uns aux autres par des barrettes de manière à former une bande assujettie à des moyens de maintien et susceptible d'avancer pas à pas sous l'effet de moyens de commande d'avance.
Selon l'invention, chaque barrette comprend au moins une branche transversale et le dispositif comprend dans un boîtier au moins une pièce de maintien élastiquement applicable sur une extrémité de la branche transversale. Chaque barrette comprend de préférence deux branches transversales situées à l'opposé l'une de l'autre, des deux côtés de la barrette, chaque branche coopérant avec une concavité d'une languette de cassette.It proposes, in general, a device for the distribution of wiring accessories, intended for the equipment of electric cables, and connected to each other by bars so as to form a strip subject to holding means. and likely to advance step by step under the effect of means of advance control.
According to the invention, each bar comprises at least one transverse branch and the device comprises in a housing at least one retaining piece which is elastically applicable on one end of the transverse branch. Each bar preferably comprises two transverse branches located opposite one another, on both sides of the bar, each branch cooperating with a concavity of a cassette tongue.

Les languettes de maintien sont avantageusement souples et leurs concavités sont agencées pour permettre l'écartement des languettes suite à une traction suffisante exercée sur la bande par les moyens d'avance.The holding tabs are advantageously flexible and their concavities are arranged to allow the tongues to be separated after sufficient traction exerted on the strip by the advancing means.

Une des deux languettes pourra avantageusement présenter un bossage constituant une rampe sur laquelle est applicable une branche transversale, ceci afin d'écarter la languette pour faciliter le passage de la bande entre les deux languettes.One of the two tongues may advantageously have a boss constituting a ramp on which a transverse branch is applicable, this in order to separate the tab to facilitate the passage of the strip between the two tabs.

Ce dispositif présente l'avantage de pouvoir distribuer des accessoires de câblage de dimensions différentes sans modification du boîtier dès lors que la somme de la longueur des barrettes et du diamètre des accessoires est égale au pas d'avance et que la hauteur des branches transversales est indépendante des dimensions précitées.This device has the advantage of being able to distribute wiring accessories of different dimensions without modifying the housing as soon as the sum of the length of the bars and the diameter of the accessories is equal to the step in advance and the height of the transverse branches is independent of the above dimensions.

Avantageusement, la bande est renfermée dans une cassette, incluant les languettes, et conçue de manière à pouvoir être fixée de manière amovible sur un appareil de sertissage comprenant les moyens de commande d'avance pas à pas de la bande, ces moyens étant applicables sur l'une au moins des branches transversales.Advantageously, the strip is enclosed in a cassette, including the tabs, and designed so as to be able to be fixed removably on a crimping apparatus comprising the means for controlling the step by step advance of the strip, these means being applicable on at least one of the transverse branches.

Un mode de réalisation de l'invention sera décrit ci-après, à titre d'exemple non limitatif, avec référence aux dessins annexés dans lesquels :

  • la figure 1 est une vue en perspective d'un conducteur électrique et d'un embout à poser et à sertir sur ce conducteur électrique ;
  • la figure 2 est une vue de face de la cassette ;
  • Les figures 3 et 4 sont respectivement des vues suivant G et suivant F de la cassette ;
  • les figures 5 à 11 représentent en vue suivant l'axe des embouts, les différentes positions que peuvent prendre la bande et les languettes de positionnement ;
  • la figure 12 représente en vue suivant l'axe des embouts, les différentes positions que peut prendre le doigt d'avance par rapport à la bande d'embouts ;
  • la figure 13 est une représentation schématique de la cassette montée sur une pince de sertissage.
An embodiment of the invention will be described below, by way of nonlimiting example, with reference to the appended drawings in which:
  • Figure 1 is a perspective view of an electrical conductor and a tip to be placed and crimped on this electrical conductor;
  • Figure 2 is a front view of the cassette;
  • Figures 3 and 4 are respectively views along G and F of the cassette;
  • Figures 5 to 11 show a view along the axis of the tips, the different positions that can take the strip and the positioning tabs;
  • Figure 12 shows a view along the axis of the tips, the different positions that can take the finger in advance relative to the strip of tips;
  • Figure 13 is a schematic representation of the cassette mounted on a crimping pliers.

Tel qu'il est représenté sur la figure 1, l'embout de câblage 4 comporte un élément métallique tubulaire 5 destiné à être engagé sur l'extrémité dénudée 7 de la partie conductrice du câble électrique 2 à équiper, et un manchon en matière isolante 6 surmoulé sur une extrémité de l'élément tubulaire et venant recouvrir l'extrémité de la gaine isolante 3 du câble.As shown in Figure 1, the wiring end 4 includes a tubular metal element 5 intended to be engaged on the stripped end 7 of the conductive part of the electrical cable 2 to be fitted, and a sleeve made of insulating material 6 molded onto one end of the tubular element and covering the end of the insulating sheath 3 of the cable.

Initialement ces embouts sont reliés les uns aux autres par des barrettes sécables de manière à constituer des bandes souples qui, enroulées sur elles-mêmes, sont logées dans des cassettes telles que celle représentée sur les figures 2, 3 et 4.
Cette cassette 9, comporte un boîtier 9a de forme plate, sensiblement parallélépipédique, avec un bord arrondi, comprenant une face avant 8 de faible épaisseur et une cavité 14 de forme sensiblement cylindrique, et de hauteur légèrement supérieure à celle des embouts. La cassette est de préférence moulée en matière plastique.Initially, these end pieces are connected to each other by breakable bars so as to form flexible strips which, wound on themselves, are housed in cassettes such as that shown in FIGS. 2, 3 and 4.
This cassette 9 comprises a box 9a of flat shape, substantially parallelepiped, with a rounded edge, comprising a front face 8 of small thickness and a cavity 14 of substantially cylindrical shape, and of height slightly greater than that of the end pieces. The cassette is preferably molded from plastic.

A l'opposé de son bord arrondi, la cavité 14 comprend une goulotte 13, de forme parallélépipédique, destinée à recevoir une extrémité de la bande d'embouts. La goulotte 13 est pourvue d'une ouverture 15 permettant la sortie des embouts. Deux languettes souples 10 et 11 de forme allongée sont associées à l'ouverture de la goulotte 13, en se raccordant par exemple aux parois internes de la goulotte 13, parallèlement à la bande, de manière à venir en contact avec chaque côté de la bande d'embouts, au niveau des manchons. En variante, un ressort pourrait être associé à l'une au moins des languettes pour la presser contre la bande. Les languettes 10, 11 viennent de moulage avec la cassette.Opposite its rounded edge, the cavity 14 comprises a chute 13, of parallelepiped shape, intended to receive one end of the strip of end pieces. The chute 13 is provided with an opening 15 allowing the outlet of the end pieces. Two flexible tongues 10 and 11 of elongated shape are associated with the opening of the trough 13, by being connected for example to the internal walls of the trough 13, parallel to the strip, so as to come into contact with each side of the strip end caps at the sleeves. Alternatively, a spring could be associated with at least one of the tabs to press it against the strip. The tongues 10, 11 come from molding with the cassette.

A proximité de l'ouverture 15, la face avant 8 présente un orifice 12 en regard duquel le dernier embout de la bande positionné par les languettes, doit être présenté. L'orifice 12 permet le passage de l'extrémité du câble à sertir dans l'embout.Near the opening 15, the front face 8 has an orifice 12 opposite which the last end of the strip positioned by the tongues must be presented. The orifice 12 allows the end of the cable to be crimped to pass through the end piece.

Afin de permettre le passage du moyen d'avance de la bande, qui peut être un doigt ou un levier, le boîtier 9a de la cassette possède une ouverture rectangulaire 16 ménagée dans sa paroi la plus proche du bord de la face avant 8. Ce moyen d'avance peut être différent, mais il est important qu'il coopère avec les branches transversales des barrettes. Une partie du moyen d'avance peut être montée dans la cassette.In order to allow passage of the means for advancing the strip, which may be a finger or a lever, the casing 9a of the cassette has a rectangular opening 16 formed in its wall closest to the edge of the front face 8. This means of advance may be different, but it is important that it cooperates with the transverse branches of the bars. Part of the feed means can be mounted in the cassette.

Comme il ressort des figures 5 à 11, la bande est formée d'embouts 21, axés parallèlement les uns aux autres, et de barrettes 17, 29 reliant deux embouts au niveau des manchons et venant de moulage avec les manchons. Les cercles 21 et 22 représentent respectivement le manchon de diamètre d et l'élément métallique tubulaire d'un embout.As is apparent from FIGS. 5 to 11, the strip is formed of end pieces 21, axially parallel to each other, and of bars 17, 29 connecting two end pieces at the level of the sleeves and coming from molding with the sleeves. The circles 21 and 22 respectively represent the sleeve of diameter d and the tubular metallic element of a nozzle.

Chacune des barrettes, en forme de croisillon, comprend une branche longitudinale 18 et deux branches transversales 19 s'étendant normalement à l'axe des embouts, la branche 18 assurant une liaison détachable ou sécable entre deux embouts.
Dans cet exemple, la hauteur des branches transversales 19 correspond au diamètre maximum des embouts que le dispositif est capable de distribuer, tandis que la longueur de la branche longitudinale 18 est adaptée au diamètre des embouts de manière à ce que la distance entre les axes de deux embouts consécutifs soit constante (pas constant). Ainsi, des bandes d'embouts de diamètres différents peuvent être logées dans des cassettes identiques.Each of the bars, in the form of a cross, comprises a longitudinal branch 18 and two transverse branches 19 extending normally to the axis of the end pieces, the branch 18 ensuring a detachable or breakable connection between two end pieces.
In this example, the height of the transverse branches 19 corresponds to the maximum diameter of the end pieces that the device is capable of distributing, while the length of the longitudinal branch 18 is adapted to the diameter of the end pieces so that the distance between the axes of two consecutive tips is constant (not constant). Thus, end strips of different diameters can be housed in identical cassettes.

Les languettes 10 et 11 ont une forme allongée et présentent chacune, à une extrémité et sur les faces en contact avec la bande, deux bosses (23, 24 et 25, 26), de forme arrondie. Sur chacune des languettes 10 et 11, ces bosses (23, 24 et 24, 26) sont disposées de manière à former entre elles une forme concave dans laquelle peut s'engager une extrémité de la branche transversale 19 de la dernière barrette 17, comme représenté sur la figure 5, et à permettre l'écartement des languettes lorsqu'on exerce une traction suffisante. Les languettes peuvent, bien entendu, comporter des prises de formes différentes pour saisir les extrémités des branches 19.The tongues 10 and 11 have an elongated shape and each have, at one end and on the faces in contact with the strip, two bumps (23, 24 and 25, 26), of rounded shape. On each of the tongues 10 and 11, these bosses (23, 24 and 24, 26) are arranged so as to form between them a concave shape in which one end of the transverse branch 19 of the last bar 17 can engage, as shown in Figure 5, and to allow the spacing of the tongues when exerting sufficient traction. The tongues can, of course, have plugs of different shapes to grip the ends of the branches 19.

Dans la position d'attente (figures 5 et 11), les deux languettes 10 et 11 sont fixées l'une en regard de l'autre sur les parois de la goulotte 13 de manière à ce que les deux extrémités 27 et 28 de la première branche transversale 19 disponible de la bande s'engagent simultanément dans les formes concaves des deux languettes 10 et 11. Dans cette position, la bande est bloquée et le dernier embout de la bande est positionné coaxialement à l'orifice 12 comme représenté sur la figure 11.In the standby position (Figures 5 and 11), the two tabs 10 and 11 are fixed opposite one another on the walls of the chute 13 so that the two ends 27 and 28 of the first available transverse branch 19 of the strip engage simultaneously in the concave shapes of the two tabs 10 and 11. In this position, the strip is locked and the last end of the strip is positioned coaxially with the orifice 12 as shown in the figure 11.

Lorsque la force de traction exercée sur la bande pour la faire avancer est supérieure à un certain seuil, les languettes souples s'écartent élastiquement pour laisser passer les branches transversales 19, le dégagement étant facilité par une rampe 20 prévue sur la languette 11 et sur laquelle vient porter l'une des branches transversales 30 de la barrette 29 suivante (figures 6 et 7).When the tensile force exerted on the strip to make it advance is greater than a certain threshold, the flexible tongues move apart elastically to allow the transverse branches 19 to pass, the release being facilitated by a ramp 20 provided on the tongue 11 and on which comes to carry one of the transverse branches 30 of the next bar 29 (Figures 6 and 7).

Le diamètre d'un manchon étant nettement supérieur à l'écart entre les deux bosses (23, 24 et 25, 26) de chaque languette, le passage du manchon entre les bosses s'effectue sans difficultés (figure 8). Lorsque le diamètre d des manchons est sensiblement égal à la hauteur h des croisillons, le manchon suivant vient en contact avec la rampe 20, et écarte la languette 11 pour faciliter le passage des branches transversales 30 entre les premières bosses 24 et 26 des languettes 10 et 11 (figure 9).The diameter of a sleeve being significantly greater than the distance between the two bosses (23, 24 and 25, 26) of each tongue, the passage of the sleeve between the bosses is carried out without difficulty (Figure 8). When the diameter d of the sleeves is substantially equal to the height h of the crossbars, the following sleeve comes into contact with the ramp 20, and spreads the tongue 11 to facilitate the passage of the transverse branches 30 between the first bumps 24 and 26 of the tongues 10 and 11 (FIG. 9).

La figure 10 montre le passage des extrémités 27, 28 des branches transversales 30 de la barrette 29 suivante sur les bosses 24 et 26 des languettes, avant son engagement dans les concavités délimitées par lesdites bosses (figure 11).Figure 10 shows the passage of the ends 27, 28 of the transverse branches 30 of the next bar 29 on the bumps 24 and 26 of the tongues, before its engagement in the concavities delimited by said bumps (Figure 11).

Dans cette dernière position, la bande est bloquée par les bosses des languettes 10 et 11 et l'embout 21 ou 22 est positionné en regard de l'orifice 12 pour recevoir le câble à sertir.In this last position, the strip is blocked by the bumps of the tongues 10 and 11 and the end piece 21 or 22 is positioned opposite the orifice 12 to receive the cable to be crimped.

L'appareil de sertissage, qui peut se présenter sous la forme d'une pince ou d'une unité de sertissage, comporte un doigt d'avance 31 se présentant par exemple sous la forme d'une équerre effaçable mobile à la fois en translation suivant un axe 35 parallèle à la bande et en rotation autour d'un axe 36 ou 36' parallèle aux axes des embouts (figure 12).The crimping device, which can be in the form of pliers or a crimping unit, comprises a feed finger 31 which is for example in the form of an erasable square which can move both in translation along an axis 35 parallel to the strip and rotating around an axis 36 or 36 'parallel to the axes of the end pieces (Figure 12).

La figure 12 montre la position du doigt d'avance dans différentes positions intermédiaires 31, 32, 33 et 34 entre la position avancée 32 et la position reculée 34.
En position avancée 32, le doigt vient en appui contre une branche transversale.
Dans les positions intermédiaires 31 et 33 le doigt s'efface en prenant appui sur un manchon 37, puis sur la branche transversale suivante 38 sans pouvoir entraîner la bande ni dans un sens ni dans l'autre.
En position reculée 34, le doigt est en prêt à pousser la bande en prenant appui sur la branche transversale suivante 38. La séquence cyclique des positions est 34, 32, 31, 33.FIG. 12 shows the position of the advance finger in different intermediate positions 31, 32, 33 and 34 between the advanced position 32 and the retracted position 34.
In the advanced position 32, the finger bears against a transverse branch.
In the intermediate positions 31 and 33 the finger is erased by bearing on a sleeve 37, then on the next transverse branch 38 without being able to drive the strip either in one direction or the other.
In the retracted position 34, the finger is ready to push the strip, pressing on the next transverse branch 38. The cyclic sequence of the positions is 34, 32, 31, 33.

Tel que représenté sur la figure 13, la cassette est montée de manière amovible sur un appareil de sertissage qui se présente sous la forme d'une pince 40 dotée d'un doigt d'avance pas à pas 41, similaire au doigt 31 qui vient d'être décrit, et s'engageant dans l'ouverture 16 de la cassette.
La pince 40 possède en outre deux mâchoires réglables 42, 43 permettant de fixer par serrage l'élément tubulaire d'un embout sur l'extrémité d'un câble électrique.As shown in Figure 13, the cassette is removably mounted on a crimping device which is in the form of a clamp 40 with a step feed finger 41, similar to the finger 31 which comes to be described, and engaging in the opening 16 of the cassette.
The clamp 40 also has two adjustable jaws 42, 43 for clamping the tubular element of a nozzle on the end of an electric cable.

Les mâchoires réglables 42, 43 présentent des dentures de différentes tailles leur permettant de s'adapter au diamètre des embouts. A cet effet, la pince comprend une molette 44 qui permet de déplacer simultanément les deux mâchoires 42, 43 pour positionner les dentures correspondant au diamètre des embouts contenus dans la cassette.The adjustable jaws 42, 43 have teeth of different sizes allowing them to adapt to the diameter of the end pieces. To this end, the clamp comprises a thumb wheel 44 which makes it possible to simultaneously move the two jaws 42, 43 to position the teeth corresponding to the diameter of the end pieces contained in the cassette.

Les mâchoires 42, 43 présentent également des parties tranchantes, qui, en même temps que s'effectue le sertissage, permettent de détacher le dernier manchon de la bande.The jaws 42, 43 also have cutting parts which, at the same time as the crimping takes place, make it possible to detach the last sleeve from the strip.

Bien entendu, le dispositif selon l'invention ne se limite pas à un type d'appareil de sertissage déterminé. Il peut être monté sur d'autres appareils tel qu'un poste de pose automatique d'embouts comportant un moyen d'entraînement de la bande.Of course, the device according to the invention is not limited to a specific type of crimping device. It can be mounted on other devices such as an automatic nozzle fitting station comprising a means for driving the strip.
