Description

L'invention concerne des embouts en bande pour conducteurs électriques, le procédé de fabrication de ces embouts et leur application à la fabrication en grande série de fils conducteurs équipés d'embouts ou de cosses fabriqués suivant le procédé.The invention relates to strip ends for electrical conductors, the method for manufacturing these ends and their application to the mass production of conductive wires fitted with ends or terminals produced according to the method.

Des embouts en forme de tube comportant une partie isolante sont déjà connus par le Brevet FR 146 8859. Toutefois, ces embouts, de par leur conception, ne permettent pas d'en automatiser la fabrication.End pieces in the form of a tube comprising an insulating part are already known from patent FR 146 8859. However, these end pieces, by their design, do not make it possible to automate their manufacture.

Ce type d'embout donne satisfaction lorsqu'il est utilisé dans des connecteurs et des plages de raccordement à serrage par vis, car la vis permet d'écraser la partie en-tube pour serrer les conducteurs entre eux. Dans leur application à des connecteurs à serrage élastique, ces embouts ne donnent par contre, pas satisfaction, car, ou bien l'embout est serti sur le connecteur par une opération préalable de sertissage, ou bien on compte sur la force élastique pour déformer la partie tubulaire et, dans ce cas, le sertissage est insuffisant, pour ne pas dire nul. Dans le cas d'un sertissage préalable, il est difficile, sans déchirer le tube, d'en déformer une portion tout en assurant un serrage suffisant pour que les conducteurs multibrins soient parfaitement jointifs et même, partiellement écrasés et déformés.This type of end piece is satisfactory when used in connectors and connection areas with screw clamping, because the screw makes it possible to crush the in-tube part to clamp the conductors together. In their application to connectors with elastic clamping, these end pieces are not satisfactory, however, because either the end piece is crimped onto the connector by a prior crimping operation, or else the elastic force is counted on to deform the tubular part and, in this case, the crimping is insufficient, not to say zero. In the case of a prior crimping, it is difficult, without tearing the tube, to deform a portion thereof while ensuring sufficient tightening so that the multi-strand conductors are perfectly contiguous and even, partially crushed and deformed.

Le brevet FR 2 468 224 divulgue un procédé de fabrication d'embouts en bande, mais ce procédé semble difficilement automatisable, car il faut introduire les tubes des manchons des embouts sur des noyaux pour pouvoir surmouler la gaine isolante et les portions de bande raccordant plusieurs embouts.Patent FR 2 468 224 discloses a method of manufacturing band end caps, but this process seems difficult to automate, because it is necessary to introduce the tubes of the end sleeves on cores in order to be able to overmold the insulating sheath and the strip portions connecting several end caps.

L'invention a pour but d'éviter ces inconvénients et de permettre une fabrication automatisée d'embouts en bande, et son application à la fabrication en grande série de fils conducteurs équipés d'embouts ou de cosses.The object of the invention is to avoid these drawbacks and to allow automated manufacture of strip end caps, and its application to the mass production of conductive wires fitted with end caps or terminals.

En plus des avantages d'automatisation de la fabrication des embouts et de l'abaissement de leur coût de production, on obtient des câbles conducteurs multibrins coupés à des longueurs standard et munis des embouts à leur extrêmité. Ceci évite que l'utilisateur doive sertir les embouts sur les câbles conducteurs, comme par le passé, pour utiliser ces embouts avec des connecteurs à serrage élastique.In addition to the advantages of automating the production of the ferrules and the lowering of their production cost, there are obtained stranded conductive cables cut to standard lengths and provided with ferrules at their ends. This prevents the user from having to crimp the ferrules on the conductive cables, as in the past, to use these ferrules with connectors with elastic clamping.

D'autre part, si l'utilisateur préfère sertir lui-même les embouts sur les câbles multibrins, on pourra, au choix, lui fournir des embouts en bande ou en tronçon de bande, ou en vrac.On the other hand, if the user prefers to crimp the end caps himself on the multi-strand cables, it is possible, as desired, to provide end caps in strip or strip section, or in bulk.

Un autre but de l'invention est de permettre la fabrication d'embouts à partir d'une bande métallique, ce qui réduit le coût de fabrication, tout en procurant des embouts que l'on peut livrer en bande.Another object of the invention is to allow the manufacture of end pieces from a metal strip, which reduces the manufacturing cost, while providing end pieces which can be supplied in strip form.

Enfin, un dernier but de l'invention est d'obtenir des embouts en bande faisant intervenir le moins grand nombre de pièces possible et de fournir un procédé de fabrication utilisant un nombre d'étapes et de reprises de pièces le plus faible possible.Finally, a final object of the invention is to obtain band ends using the least number of parts possible and to provide a manufacturing process using the lowest possible number of steps and rework of parts.

Selon l'invention, un embout pour câble conducteur multibrins, destiné à sertir les conducteurs multibrins, est caractérisé en ce qu'il comprend une forme découpée dans une bande métallique présentant un corps rectangulaire conformé en goulotte, une tête surmoulée en matière plastique et conformée au moins en goulotte, et un col reliant le corps à la tête.According to the invention, a ferrule for multi-stranded conductor cable, intended for crimping multi-stranded conductors, is characterized in that it comprises a shape cut from a metal strip having a rectangular body shaped as a trough, a head overmolded in plastic material and shaped at least in a chute, and a collar connecting the body to the head.

Le procédé suivant l'invention, appliqué à la fabrication de câbles conducteurs équipés d'embouts, comprend en outre les opérations suivantes :

  • - introduction du câble conducteur dans l'embout,
  • - sertissage du corps sur les conducteurs multibrins.
The process according to the invention, applied to the manufacture of conductive cables fitted with end caps, further comprises the following operations:
  • - introduction of the conductive cable into the end piece,
  • - body crimping on multi-strand conductors.

La figure 1 représente un premier mode de réalisation de l'embout et les différentes étapes du procédé de fabrication. Comme représenté, on obtient l'embout à partir d'une bande métallique conductrice de l'électricité découpée selon la forme figurée à l'étape A du procédé. Cette forme 1 comprend un corps principal 10 de forme rectangulaire, une tête 11 comportant des découpes en queue d'aronde 12 ; cette tête est reliée au corps 10 par un col 13. L'ensemble de la découpe constitutive de l'embout est relié à la bordure de la bande métallique 14 par un appendice 15. La bande entraînée par les trous 19 va passer par des postes de travail successifs où elle va subir des opérations B, C, D, E, F, G.FIG. 1 represents a first embodiment of the end piece and the different stages of the manufacturing process. As shown, the end piece is obtained from an electrically conductive metal strip cut according to the shape shown in step A of the process. This form 1 comprises a main body 10 of rectangular shape, a head 11 comprising dovetail cutouts 12; this head is connected to the body 10 by a neck 13. The entire cutout constituting the end piece is connected to the edge of the metal strip 14 by an appendage 15. The strip driven by the holes 19 will pass through stations successive work where she will undergo operations B, C, D, E, F, G.

Une fois la découpe effectuée, on donne une forme de goulotte à la tête 11 et au corps 10 par estampage. Ceci constitue la deuxième phase B du procédé. Au cours de l'opération C ultérieure, on donne à la tête 11 une forme de couronne ou d'anneau fendu représentée à l'étape C.Once the cutting has been carried out, the head 11 and the body 10 are given a form of trough by stamping. This constitutes the second phase B of the process. During the subsequent operation C, the head 11 is given the shape of a split crown or ring shown in step C.

A l'étape D, les embouts en bande sont introduits dans une machine à mouler les matières plastiques qui effectue un surmoulage de la tête 11 avec une matière plastique isolante 16. On obtient ainsi des embouts en bande continue, dont les appendices 15 peuvent être éventuellement découpés si l'on souhaite livrer les embouts en vrac.In step D, the strip end pieces are introduced into a plastic molding machine which overmoulds the head 11 with an insulating plastic material 16. Continuous strip end pieces are thus obtained, the appendages 15 of which can be possibly cut if you want to deliver the tips in bulk.

Un dernière étape E vient s'ajouter lorsque l'on veut obtenir des câbles conducteurs multibrins 2 revêtus d'une gaine isolante 20, ces câbles étant équipés d'embouts à leurs extrémités, comme le représente la figure 2.A final step E is added when it is desired to obtain multi-strand conductive cables 2 coated with an insulating sheath 20, these cables being fitted with end caps at their ends, as shown in FIG. 2.

Cette dernière phase comprend l'étape E représentée à la figure 3, sur laquelle on peut voir une bande d'embouts surmoulés au poste d'introduction des câbles conducteurs multibrins 2.This last phase includes step E shown in Figure 3, on which we can see a strip of tips overmolded at the insertion station for multi-strand conductor cables 2.

Les câbles conducteurs 2, préalablement découpés à des longueurs normalisées et dénudés à leurs extrémités, sont introduits axialement dans la tête cylindrique surmoulée, jusqu'à ce que la gaine 20 vienne en butée contre les bossages 161 représentés à la figure 4. Les conducteurs multibrins 21 se trouvent alors en vis-à-vis de la portion conductrice du corps 10, puis sont sertis dans l'embout à l'étape F.The conductive cables 2, previously cut to standardized lengths and stripped at their ends, are introduced axially into the overmolded cylindrical head, until the sheath 20 abuts against the bosses 161 shown in FIG. 4. The multi-strand conductors 21 are then facing the conductive portion of the body 10, then are crimped in the end piece in step F.

Le fait qu'à chaque étape, le travail effectué ait été représenté sur une seule découpe, n'exclut pas que, dans le procédé, on découpe, estampe, surmoule, sertisse, en une seule fois plusieurs embouts. Cette remarque est également valable pour la suite de la description.The fact that at each stage, the work carried out has been represented on a single cut, does not exclude that, in the process, one cuts, stamps, molds, crimps, in one go several end pieces. This remark is also valid for the rest of the description.

A l'étape G, qui est facultative, les conducteurs munis d'embouts sont désolidarisés de la bande en sectionnant l'appendice 15.In step G, which is optional, the conductors fitted with end caps are separated from the strip by cutting off appendix 15.

Lors de la phase C, la denture en queue d'aronde 12 est légèrement évasée suivant un angle de l'ordre de 30°, comme le représente la figure 4. La conicité donnée aux dents 12 permet d'obtenir un bon ancrage de la partie métallique de l'embout dans la matière plastique surmoulée. Comme on peut le voir sur la figure 4, la partie surmoulée 16 comporte une portion conique 163 de guidage des multibrins, ainsi qu'une portion cylindrique 164 munie de bossages internes 161 pour immobiliser la gaine isolante du câble conducteur. Facultativement, on peut prévoir sur le surmoulage une languette formant crochet 162 destinée à recevoir des index de repérage. Une telle languette est bien connue de l'homme de l'art et déjà décrite dans le Brevet FR 1 468 859.During phase C, the dovetail teeth 12 are slightly flared at an angle of the order of 30 °, as shown in FIG. 4. The conicity given to the teeth 12 makes it possible to obtain a good anchoring of the metal part of the nozzle in the overmolded plastic. As can be seen in FIG. 4, the overmolded part 16 comprises a conical portion 163 for guiding the multi-strands, as well as a cylindrical portion 164 provided with internal bosses 161 for immobilizing the insulating sheath of the conductive cable. Optionally, there can be provided on the overmolding a tongue forming a hook 162 intended to receive index markers. Such a tongue is well known to those skilled in the art and already described in Patent FR 1,468,859.

La figure 5 représente un deuxième mode de réalisation des embouts et les différentes étapes du procédé.FIG. 5 represents a second embodiment of the end pieces and the different stages of the method.

Dans la première étape A, on retrouve les différentes parties de la pièce découpée qui va permettre de réaliser l'embout. Sur cette figure, la référence 12 désigne, non plus des créneaux en queue d'aronde, mais des trous d'ancrage de la partie surmoulée, comme on l'expliquera dans la suite. Ensuite, la bande est amenée à un poste où la pièce 1 subit une opération d'estampage, de façon à donner à ladite pièce une forme de goulotte, comme représenté à l'étape B.In the first step A, we find the different parts of the cut piece that will allow the tip to be produced. In this figure, the reference 12 designates, no longer dovetail slots, but anchoring holes of the overmolded part, as will be explained below. Then, the strip is brought to a station where the piece 1 undergoes a stamping operation, so as to give said piece the shape of a chute, as shown in step B.

Au poste suivant, chaque pièce ou ensemble de pièces subit une opération de surmoulage C, avec de la matière plastique, de tout ou partie de la tête 11.At the following station, each part or set of parts is subjected to an overmolding operation C, with plastic material, of all or part of the head 11.

A l'étape suivante D, un câble conducteur 2, dénudé sur une portion 21, tombe verticalement dans la goulotte de chaque pièce 1, de façon que la partie isolante 20 du câble coincide avec la portion surmoulée 16 et que la portion dénudée 18 soit en face de la portion conductrice 10 de l'embout. Cette opération est suivie de l'opération de sertissage d'un ou de plusieurs embouts, figurée à l'étape E. Dans cette opération, la partie métallique 10 est sertie sur le conducteur multibrins 21, tandis que la partie surmoulée vient serrer la gaine isolante 20. Cette opération peut être suivie d'une opération G, non représentée, de découpe de l'appendice 15.In the next step D, a conductive cable 2, stripped on a portion 21, falls vertically into the trough of each piece 1, so that the insulating part 20 of the cable coincides with the overmolded portion 16 and that the stripped portion 18 is opposite the conductive portion 10 of the nozzle. This operation is followed by the crimping operation of one or more end caps, shown in step E. In this operation, the metal part 10 is crimped onto the multi-strand conductor 21, while the overmolded part tightens the sheath insulating 20. This operation can be followed by an operation G, not shown, of cutting the appendix 15.

Sur la figure 6, on distingue le décalage axial entre la portion 11 et la partie 10, qui est nécessaire pour que l'axe des brins conducteurs se confonde avec celui de la gaine isolante 20. Ce décalage est obtenu, au cours de l'opération d'estampage B, par déformation du col 13 reliant le corps 10 à la tête 11. Sur cette figure, on voit également que la matière plastique surmoulée 16 est ancrée sur la tête par les trous 12. Comme précédemment, il est également possible de prévoir une languette 162 servant de porte-index.In FIG. 6, a distinction is made between the axial offset between the portion 11 and the portion 10, which is necessary so that the axis of the conductive strands merges with that of the insulating sheath 20. This offset is obtained during the stamping operation B, by deformation of the neck 13 connecting the body 10 to the head 11. In this figure, it can also be seen that the overmolded plastic material 16 is anchored on the head by the holes 12. As before, it is also possible to provide a tab 162 serving as an index holder.

La figure 7a représente une variante d'un embout obtenu selon le premier mode de réalisation avec, à la place de la languette 162, une ouverture rectangulaire 165 permettant la fixation d'une languette porte-étiquette non représentée et du type mentionné ci-dessus.FIG. 7a represents a variant of a nozzle obtained according to the first embodiment with, in place of the tongue 162, a rectangular opening 165 allowing the fixing of a label-carrying tongue not shown and of the type mentioned above .

Les figures 8, 9, 10, 11 représentent différentes applications des embouts obtenus selon le deuxième mode de réalisation pour obtenir des embouts à cosses.Figures 8, 9, 10, 11 show different applications of the ends obtained according to the second embodiment for obtaining end caps.

Pour ces différentes applications, les embouts, dans lesquels on retrouve les différentes parties constitutives ; 16 la partie surmoulée ; 10 la partie sertissable et 13 le col de jonction (non figuré) entre les deux parties 16 et 10, sont prolongés par un deuxième col de jonction 30 de la partie sertissable à une portion 31, 32, 33 ou 34 constituant une cosse de connexion. Cette portion de cosse de jonction peut avoir, comme représenté sur les figures 8, 9, 10, 11, toute forme permettant de réaliser tous les types de fixation et de connexion que l'on désire.For these different applications, the tips, in which there are the various constituent parts; 16 the overmolded part; 10 the crimpable part and 13 the junction neck (not shown) between the two parts 16 and 10, are extended by a second junction neck 30 of the crimpable part to a portion 31, 32, 33 or 34 constituting a connection terminal . This portion of junction terminal can have, as shown in Figures 8, 9, 10, 11, any shape allowing to achieve all types of fixing and connection that is desired.

Les cosses 31 et 32 permettent une connexion par vis, tandis que les cosses 33 et 34 du type connu dans la littérature anglo-saxonne sous le nom de "fast-on" permettent une connexion par serrage. Les formes des cosses 31, 32, 33, 34 sont obtenues, au cours du procédé de fabrication, par découpage et pliage de la bande métallique et sont reliées à la bande par les languettes 15. Le même procédé de fabrication des embouts montés en série sur des câbles conducteurs de longueur standard s'applique aux embouts à cosses. Il suffit donc de prévoir, dans les opérations de fabrication, les opérations de découpage du deuxième col 30 et du deuxième corps 31, 32, 33, 34 ainsi que les opérations de formage en forme de cosse.The lugs 31 and 32 allow a connection by screws, while the lugs 33 and 34 of the type known in the Anglo-Saxon literature under the name of "fast-on" allow a connection by tightening. The shapes of the lugs 31, 32, 33, 34 are obtained, during the manufacturing process, by cutting and bending the metal strip and are connected to the strip by the tongues 15. The same process for manufacturing the ends assembled in series on conductor cables of standard length applies to terminal lugs. It is therefore sufficient to provide, in the manufacturing operations, for the cutting operations of the second neck 30 and of the second body 31, 32, 33, 34 as well as the lug-shaped forming operations.

Les parties surmoulées peuvent être également pourvues de moyens porte-étiquette.The overmolded parts can also be provided with label holder means.

Ces différentes applications des embouts peuvent également être faites aux embouts obtenus selon le premier mode de réalisation. Dans ce cas, au lieu d'obtenir un élément surmoulé en forme de goulotte, la partie surmoulée sera cylindrique comme dans l'étape D de la figure 1. Les autres parties 31 à 34 seront identiques et reliées par un col 30 à la partie sertissable.These different applications of the tips can also be made to the tips obtained according to the first embodiment. In this case, instead of obtaining an overmolded element in the form of a chute, the overmolded part will be cylindrical as in step D of FIG. 1. The other parts 31 to 34 will be identical and connected by a neck 30 to the part crimpable.

Il est également possible, lors de l'opération de surmoulage, de relier entre elles toutes les parties surmoulées 16 par des barrettes ou languettes ; après avoir découpé les appendices 15, on relie alors les embouts en bande par la partie surmoulée, comme cela est connu par le brevet FR 2 468 224.It is also possible, during the overmolding operation, to connect together all of the overmolded parts 16 by bars or tabs; after having cut the appendages 15, the end caps are then connected by the overmolded part, as is known from patent FR 2 468 224.

Il va de soi que diverses autres modifications et variantes pourront être imaginées par l'homme de l'art, sans s'écarter de l'esprit de l'invention.It goes without saying that various other modifications and variants could be imagined by those skilled in the art, without departing from the spirit of the invention.
