Description

La présente invention a pour objet une pièce de connexion électrique polyvalente et notamment une pièce de connexion électrique à raccordement autodénudant et à prise complémentaire.The present invention relates to a versatile electrical connection part and in particular an electrical connection part with insulation displacement connection and with complementary socket.

Les pièces de connexion électriques autodénudantes pour fils électriques sont couramment incluses dans de nombreux organes de raccordement et en particulier dans de nombreux blocs de jonction ; elles présentent l'avantage de permettre un raccordement rapide, simple et sûr par rapport aux moyens plus anciens, tels que les moyens de raccordement par système à vis et à écrou.Self-stripping electrical connection parts for electrical wires are commonly included in many connection members and in particular in many terminal blocks; they have the advantage of allowing a quick, simple and safe connection compared to older means, such as the connection means by screw and nut system.

Chaque pièce de connexion est destinée à assurer une liaison électrique soit entre deux fils, soit entre un fil et un organe électrique ; lorsqu'elle est autodénudante elle comporte donc au moins une partie autodénudante et au moins une autre partie adaptée au besoin spécifique à remplir, soit par exemple une languette, une lyre ou éventuellement une autre partie autodénudante.Each connection piece is intended to provide an electrical connection either between two wires, or between a wire and an electrical member; when it is self-stripping it therefore comprises at least one self-stripping part and at least one other part adapted to the specific need to be fulfilled, for example a tongue, a lyre or possibly another self-stripping part.

Or, dans de nombreux cas de raccordement, l'utilisateur souhaite avoir accès aux liaisons électriques réalisées à l'aide de telles pièces de connexion afin par exemple de réaliser des dérivations, des distributions, ou de pouvoir sectionner temporairement la liaison ou encore de pouvoir effectuer des tests de continuité.However, in many connection cases, the user wishes to have access to the electrical connections made using such connection parts in order for example to make branches, distributions, or to be able to temporarily cut the connection or to be able to perform continuity tests.

Les opérations peuvent parfois être réalisées à divers niveaux des installations, mais il est souvent très pratique de pouvoir les effectuer sur les pièces de connexion généralement plus accessibles que les appareillages et usuellement rassemblées en un ou plusieurs emplacements pour faciliter les modifications, les mises hors-services, etc.....The operations can sometimes be carried out at various levels of the installations, but it is often very practical to be able to carry them out on the connection parts generally more accessible than the apparatuses and usually assembled in one or more locations to facilitate modifications, decommissions. services, etc .....

On prévoit donc des prises complémentaires spécialisées sur les pièces de connexion évoquées ci-dessus en vue de répondre aux besoins spécifiques à remplir. Toutefois il apparaît clairement qu'on ne peut raisonnablement prévoir de fabriquer de manière habituelle différentes pièces de connexion correspondant à toutes les combinaisons possibles d'une partie autodénudante telle qu'évoquées ci-dessus avec les différentes variantes de prises complémentaires adaptées aux besoins spécifiques à remplir.We therefore provide specialized additional sockets on the connection parts mentioned above in order to meet the specific needs to be fulfilled. However, it clearly appears that it cannot reasonably be expected to manufacture in the usual way different connection parts corresponding to all the possible combinations of a insulation displacement part as mentioned above with the different variants of complementary sockets adapted to the specific needs of fill.

La présente invention propose donc une pièce de connexion électrique polyvalente permettant de réaliser des montages différents et en particulier des raccordements dans différentes directions à l'aide du même modèle de pièce.The present invention therefore provides a versatile electrical connection part making it possible to produce different assemblies and in particular connections in different directions using the same model of part.

Selon l'invention, la pièce de connexion électrique polyvalente comportant au moins une partie autodénudante se présentant sous la forme d'un élément métallique, bon conducteur, doué d'élasticité, qui est muni d'une fente de coincement de fil débouchant dans un évasement de dénudage d'isolant dont les bords sont affûtés de manière à entamer l'isolant du fil à connecter avant introduction de l'âme du fil dans la fente, est caractérisée en ce qu'elle comporte en outre au moins une prise complémentaire formée à partir d'un prolongement de l'élément métallique constituant la partie autodénudante et constituée par une paire de lyres de contact dont les bases sont parallèles et face à face pour permettre une connexion via ces bras, selon l'une ou l'autre de trois directions perperdiculaires.According to the invention, the multipurpose electrical connection piece comprising at least one insulation displacement part in the form of a metallic element, good conductor, endowed with elasticity, which is provided with a thread jamming slot opening into a flaring of insulation stripping whose edges are sharpened so as to start the insulation of the wire to be connected before introduction of the core of the wire into the slot, is characterized in that it also comprises at least one complementary socket formed from an extension of the metal element constituting the insulation displacement part and constituted by a pair of contact lyres whose bases are parallel and face to face to allow a connection via these arms, according to either three perperdicular directions.

Pour améliorer le contact avec une pièce de connexion avec mise en liaison selon une direction parallèle aux lyres, les deux lyres d'une même paire sont inclinées l'une vers l'autre au niveau de leurs bras respectifs.To improve contact with a connection piece with connection in a direction parallel to the lyres, the two lyres of the same pair are inclined towards one another at their respective arms.

L'invention sera décrite ci-après plus en détail en relation avec les figures mentionnées ci-dessous.

  • La figure 1 présente une pièce double de connexion électrique selon l'invention.
  • La figure 2 présente un exemple de montage de doubles pièces de connexion selon la figure 1, avec mise en liaison selon une direction perpendiculaire aux lyres.
  • La figure 3 présente un exemple de mise en oeuvre d'une pièce de connexion selon la figure 1, avec mise en liaison selon une direction axiale.
  • La figure 4 présente un exemple de mise en oeuvre de deux pièces simples de connexion selon l'invention, avec mise en liaison selon une direction perpendiculaire aux lyres.
  • La figure 5 présente un exemple de mise en oeuvre de deux pièces simples de connexion selon l'invention avec mise en liaison selon une direction parallèle aux lyres.
The invention will be described below in more detail with reference to the figures mentioned below.
  • Figure 1 shows a double piece of electrical connection according to the invention.
  • Figure 2 shows an example of mounting double connection pieces according to Figure 1, with connection in a direction perpendicular to the lyres.
  • Figure 3 shows an example of implementation of a connection piece according to Figure 1, with connection in an axial direction.
  • Figure 4 shows an example of implementation of two simple connection parts according to the invention, with connection in a direction perpendicular to the lyres.
  • FIG. 5 shows an example of implementation of two simple connection parts according to the invention with connection according to a direction parallel to the lyres.

La pièce de connexion 1 présentée figure 1 est composée de deux parties symétriques par rapport au plan médian, et l'on obtient deux pièces de connexion simples par sectionnement d'une pièce double selon ce plan médian. Ceci permet donc de réaliser avec les mêmes moyens soit une pièce double soit deux pièces symétriques et ici identiques.The connection piece 1 presented in FIG. 1 is made up of two parts that are symmetrical with respect to the median plane, and two simple connection pieces are obtained by cutting a double piece along this median plane. This therefore makes it possible to produce with the same means either a double part or two symmetrical parts and here identical.

La pièce de connexion double est nécessairement en un métal bon conducteur, doué d'élasticité, ce métal est découpé et plié pour obtenir la forme désirée.The double connection piece is necessarily made of a good conductive metal, endowed with elasticity, this metal is cut and bent to obtain the desired shape.

La pièce 1 comporte au moins un élément 2, tel 2A ou 2B, muni d'une fente 20, telle 20A ou 20B, pour le coincement de l'âme A3 d'un fil 3 à raccorder. Chaque fente 20 débouche dans un évasement 21, telle 21A ou 21B, servant au dénudage de l'isolement des fils à raccorder, tel I3 pour le fil 3.The part 1 comprises at least one element 2, such as 2A or 2B, provided with a slot 20, such as 20A or 20B, for wedging the core A3 of a wire 3 to be connected. Each slot 20 opens into a flare 21, such as 21A or 21B, used to strip the insulation of the wires to be connected, such as I3 for wire 3.

Les bords des évasements sont partiellement affûtés de manière à entamer l'isolant des fils sans détériorer l'âme lors de l'opération de raccordement pendant laquelle chaque fil est poussé dans une fente via l'évasement qui la précède.The edges of the flares are partially sharpened so as to start the insulation of the wires without damaging the core during the connection operation during which each wire is pushed into a slot via the flaring which precedes it.

La pièce 1 comporte de plus un prolongement issu de l'élément 2. Le prolongement 4 porte au moins une paire de lyres 5L, 5L', il en posséde préférablement deux paires 5LA, 5L'A et 5LB, 5L'B.The part 1 further comprises an extension from the element 2. The extension 4 carries at least one pair of lyres 5L, 5L ', it preferably has two pairs 5LA, 5L'A and 5LB, 5L'B.

Chaque lyre posséde une base, telle 5LA1 ou 5LB1 et deux bras, tels 5L'A2 et 5L'A3 pour la lyre 5L'A ou 5LB2 et 5LB3 pour la lyre 5LB, les deux bras d'une lyre comportent chacun un renflement 6LB, tels 6LB2 et 6LB3, se faisant face de manière à prendre appui sur tout élément d'épaisseur appropriée qui serait inséré entre eux.Each lyre has a base, such as 5LA1 or 5LB1 and two arms, such as 5L'A2 and 5L'A3 for the lyre 5L'A or 5LB2 and 5LB3 for the lyre 5LB, the two arms of a lyre each have a bulge 6LB, such 6LB2 and 6LB3, facing each other so as to bear on any element of appropriate thickness which would be inserted between them.

De même de tels renflements tel 13 sont prévus pour le même objet sur les faces en regard des bras des deux lyres d'une paire, telles 5LA et 5L'A (figure 5).Similarly, such bulges such as 13 are provided for the same object on the opposite faces of the arms of the two lyres of a pair, such as 5LA and 5L'A (FIG. 5).

En effet, les deux lyres de chaque paire ont leurs bases parallèles et face à face telles les bases 5LA1 et 5L'A1 (figure 1), et elles sont identiquement inclinées par leurs bras l'une vers l'autre, de manière à ce que ces bras viennent identiquement prendre appui sur tout élément cylindrique de diamètre approprié qui serait inséré entre eux.Indeed, the two lyres of each pair have their bases parallel and face to face such as bases 5LA1 and 5L'A1 (Figure 1), and they are identically inclined by their arms towards each other, so that that these arms come identically to bear on any cylindrical element of appropriate diameter which would be inserted between them.

Selon une réalisation préférée de l'invention, les quatre bras, d'une paire de lyres telles 5LA, 5L'A définissent pratiquement un carré dont les diagonales correspondent grossièrement au diamètre de l'élément cylindrique insérable entre eux.According to a preferred embodiment of the invention, the four arms, of a pair of lyres such as 5LA, 5L'A practically define a square whose diagonals roughly correspond to the diameter of the cylindrical element insertable between them.

La pièce à connexion 1 est réalisée par découpe et pliage à partir d'une bande métallique plane ; les découpes déterminent les parties destinées à constituer les éléments autodénudants 2, le prolongement 4 et les lyres. Une succession de pliages effectués aux deux extrémités de chaque plan découpé permet de constituer deux parallélépidèdes rectangles 2A, 2B ouverts chacun sur deux faces parallèles et reliés entre eux par le prolongement 4 de manière que les lyres également positionnées par pliage soient disposées en succession entre les parallélépipèdes rectangles 2A, 2B de l'autre côté de ceux-ci par rapport au plan du prolongement 4 et des deux faces ouvertes dans lesquels débouchent les évasements 21A et 21B.The connection piece 1 is produced by cutting and folding from a flat metal strip; the cutouts determine the parts intended to constitute the insulation-displacement elements 2, the extension 4 and the lyres. A succession of folds carried out at the two ends of each cut plane makes it possible to constitute two rectangular parallelepideds 2A, 2B each open on two parallel faces and connected together by the extension 4 so that the lyres also positioned by folding are arranged in succession between the rectangular parallelepipeds 2A, 2B on the other side of these with respect to the plane of the extension 4 and the two open faces into which the flares 21A and 21B open.

Les fentes 20 et les évasements 21 sont ménagés dans les petits côtés des parallélépipèdes rectangles qui sont à l'extérieur de la pièce 1 alors que le prolongement prend naissance au sommet des petits côtés des parallélépidèdes rectangles qui sont à l'intérieur de la pièce 1.The slots 20 and the flares 21 are formed in the short sides of the rectangular parallelepipeds which are outside of the part 1 while the extension originates at the top of the short sides of the rectangular parallelepidedes which are inside the part 1 .

Suivant les besoins la pièce 1 peut être utilisée telle que, ou séparée en deux moitiés symétriques ou dissymétriques par découpage du prolongement 4 entre ou avant les paires de lyres.According to the needs, the part 1 can be used as, or separated into two symmetrical or asymmetrical halves by cutting the extension 4 between or before the pairs of lyres.

De manière usuelle elle est logée dans un boîtier en matériau isolant qui permet sa fixation et sa combinaison avec des pièces identiques ou compatibles.Usually it is housed in a housing made of insulating material which allows it to be fixed and combined with identical or compatible parts.

Ainsi qu'évoqué plus haut la pièce de connexion permet d'effectuer des raccordements selon trois directions différentes au niveau des lyres en plus des raccordements par autodénudage.As mentioned above, the connection piece makes it possible to make connections in three different directions at the level of the lyres in addition to the connections by self-stripping.

La figure 2 montre comment il est possible de raccorder une pluralité de pièces de connexion 1, 1', 1", 1"' selon l'invention au moyen de barres conductrices 7, telles 7 et 7' insérées entre les bras des lyres telles 5LB1, 5LB2 perpendiculairement à ces lyres, chaque barre ayant une largeur légèrement supérieure à la distance minimale entre bras d'une même lyre au niveau des renflements 6LB (figure 1) de manière à y être coincée en prenant préférablement appui en fond de lyre.Figure 2 shows how it is possible to connect a plurality of connection pieces 1, 1 ', 1 ", 1"' according to the invention by means of conductive bars 7, such 7 and 7 'inserted between the arms of the lyres 5LB1, 5LB2 perpendicular to these lyres, each bar having a width slightly greater than the minimum distance between arms of the same lyre at the level of the bulges 6LB (FIG. 1) so as to be wedged there preferably taking support at the bottom of the lyre.

Il est possible d'assurer une distribution sur une longueur excédant celle d'une barre en utilisant une ou plus d'une pièce de connexion, pour assurer la liaison entre barres successives, telle la pièce 1" entre les barres 7 et 7'.It is possible to provide a distribution over a length exceeding that of a bar by using one or more of a connecting piece, to ensure the connection between successive bars, such as the piece 1 "between the bars 7 and 7 '.

La figure 3 montre, comment il est possible de connecter une fiche cylindrique mâle 8 reliée à un fil 80 avec une pièce de connexion 1, par exemple dans un but d'essai, en choisissant une fiche de diamètre légèrement supérieure à la distance entre deux bras en diagonale d'une paire de lyres.FIG. 3 shows how it is possible to connect a male cylindrical plug 8 connected to a wire 80 with a connection piece 1, for example for testing purposes, by choosing a plug with a diameter slightly greater than the distance between two diagonal arm of a pair of lyres.

En ce but on enfiche la partie conductrice 8 entre les bras inclinés d'une paire de lyres tels les bras 5LB2, 5LB3, 5L'B2, 5L'B3, de telle sorte que cette pièce soit maintenue en place par la force élastique de rappel en position initiale de ces bras également écartés deux à deux.For this purpose, the conductive part 8 is plugged between the inclined arms of a pair of lyres such as the arms 5LB2, 5LB3, 5L'B2, 5L'B3, so that this part is held in place by the elastic return force. in the initial position of these arms also separated two by two.

Bien entendu un tel raccordement axial est envisageable tant dans le cas de la pièce de connexion double ici représentée que dans le cas d'une pièce de connexion simple telle que présentée en 2A à la figure 4.Of course, such an axial connection can be envisaged both in the case of the double connection part shown here and in the case of a single connection part as shown in 2A in FIG. 4.

La figure 4 montre comment il est possible de mettre en oeuvre deux pièces de connexion simples 2A et 2B obtenue par sectionnement d'une pièce de connexion 1 selon son plan médian de symétrie entre les deux groupes de lyres 5LA, 5L'A d'une part et 5LB, 5L'B d'autre part, pour réaliser une jonction interruptible à la demande.Figure 4 shows how it is possible to implement two simple connection pieces 2A and 2B obtained by sectioning a connection piece 1 according to its median plane of symmetry between the two groups of lyres 5LA, 5L'A of a part and 5LB, 5L'B on the other hand, to make an interruptible junction on demand.

En ce but on utilise une barrette de raccordement 9 amovible dotée de deux lames de contact 9A, 9B interconnectées, qui présentent chacune une épaisseur légèrement supérieure à la distance minimale entre bras d'une même lyre au niveau des renflements et une longueur égale ou légèrement supérieure à la distance entre les deux lyres face à face d'une même pièce de connexion simple. Ayant supposé que les deux pièces de connexion simple 2A et 2B sont contenues avec leurs lyres dans un boîtier de connexion où elles sont assujetties, il est donc possible d'établir ou de rompre à volonté une liaison entre pièces 2A et 2B par introduction ou retrait des lames de contact 9A et 9B d'entre les deux bras des lyres respectives de chaque pièce, ces bras appuyant par leurs renflements 6L, 6L' sur lesdites lames par pression élastique.For this purpose, a removable connection strip 9 is used, provided with two interconnected contact blades 9A, 9B, which each have a thickness slightly greater than the minimum distance between arms of the same lyre at the level of the bulges and a length equal or slightly greater than the distance between the two lyres facing each other from the same single connection piece. Assuming that the two simple connection parts 2A and 2B are contained with their lyres in a connection box where they are secured, it is therefore possible to establish or break at will a connection between parts 2A and 2B by introduction or removal contact blades 9A and 9B between the two arms of the respective lyres of each part, these arms pressing by their bulges 6L, 6L 'on said blades by elastic pressure.

La figure 5 montre une autre variante de raccordement mettant en oeuvre deux pièces de connexion simples 2A et 2B avec leurs lyres et un couteau comportant un corps isolant 10 porteur d'une lame de contact 11 et monté sur un axe 12 solidaire du boîtier, non figuré, contenant de manière fixe les pièces de connexion 2A et 2B et leurs lyres respectives 5LA, 5L'A, 5LB et 5L'B.Figure 5 shows another connection variant highlighting works two simple connection pieces 2A and 2B with their lyres and a knife comprising an insulating body 10 carrying a contact blade 11 and mounted on an axis 12 secured to the housing, not shown, fixedly containing the connection pieces 2A and 2B and their respective lyres 5LA, 5L'A, 5LB and 5L'B.

Le couteau est disposé parallèlement aux bases des lyres de manière que sa lame de contact 11 viennent s'insérer par rotation d'une part entre les lyres 5LA et 5L'A et la pièce 2A et d'autre 5LB et 51'B de la pièce 2B supposées alignées dans leur boîtier.The knife is arranged parallel to the bases of the lyres so that its contact blade 11 is inserted by rotation on the one hand between the lyres 5LA and 5L'A and the part 2A and on the other 5LB and 51'B of the part 2B assumed to be aligned in their casing.

Les contacts s'effectuent alors parallèlement aux bases des lyres, les deux bras de chaque lyre s'écartant parallèlement et identiquement vers l'extérieur par rapport à leur position initiale, sous l'action de la lame 11.The contacts are then made parallel to the bases of the lyres, the two arms of each lyre moving apart and identically outwardly from their initial position, under the action of the blade 11.
