Description

La présente invention concerne un dispositif pour raccorder électriquement un câble principal avec une barre conductrice et / ou avec un ou plusieurs câbles secondaires.The present invention relates to a device for electrically connecting a main cable with a busbar and / or with one or more secondary cables.

On sait que dans les installations électriques basse-tension, on doit raccorder un câble principal avec divers câbles secondaires, dirigés vers des consommateurs et pouvoir connecter, à l'aide d'une cosse, un câble supplémentaire de branchement provisoire ou de réalimentation.We know that in electrical installations low voltage, a main cable must be connected with various secondary cables, routed to consumers and be able to connect, using a lug, an additional temporary connection cable or make-up.

Ce raccordement est généralement effectué au moyen de serre-câbles reliés électriquement entre eux, au moyen de barres conductrices, elles-mêmes fixées sur des éléments isolants.This connection is generally made at means of cable ties electrically connected to each other, by means of conductive bars, themselves fixed on insulating elements.

Les serre-câbles comprennent chacun une ou deux mâchoires serrées sur le câble.Cable ties each include one or two jaws tightened on the cable.

Le document FR 2 436 509 décrit par ailleurs un connecteur adapté pour relier au moins deux câbles dont l'un est en liaison avec un éclateur parafoudre, ce connecteur comprenant également deux mâchoires.Document FR 2 436 509 also describes a connector suitable for connecting at least two cables including one is in connection with a surge arrester, this connector also comprising two jaws.

Le but de la présente invention est de simplifier ces dispositifs de raccordements, tout en améliorant la connexion électrique et la protection électrique.The object of the present invention is to simplify these connection devices, while improving electrical connection and protection electric.

L'invention vise ainsi un dispositif pour raccorder électriquement un câble électrique principal avec une barre conductrice et / ou avec un ou plusieurs câbles secondaires, ces câbles comportant une âme conductrice entourée par une gaine isolante, le dispositif comprenant au moins deux mâchoires dentelées munies de dents disposées les unes en regard des autres, pour serrer le câble principal et traverser la gaine isolante pour venir en contact avec l'âme conductrice, et des moyens de raccordement électrique avec la barre conductrice et/ou les câbles secondaires.The invention thus relates to a device for electrically connect a main electric cable with a busbar and / or with one or more secondary cables, these cables having a core conductive surrounded by an insulating sheath, the device comprising at least two serrated jaws with teeth arranged opposite one another, to tighten the main cable and pass through the sheath insulating to come into contact with the conductive core, and means of electrical connection with the bar conductor and / or secondary cables.

Suivant l'invention, ce dispositif est caractérisé en ce qu'il comprend un élément métallique réalisé d'une seule pièce par découpage et pliage d'une tôle en métal conducteur, cet élément comportant les mâchoires dentelées et étant disposé dans un bloc en matière isolante duquel font saillie les dents des mâchoires, ce bloc étant recouvert par au moins un autre bloc en matière isolante, des moyens de serrage étant prévus pour serrer ledit autre bloc sur le câble principal s'étendant sur les mâchoires, et en ce que les deux mâchoires sont reliées l'une à l'autre par une bande de la tôle découpée.According to the invention, this device is characterized in that it comprises a metallic element made in one piece by cutting and folding a conductive metal sheet, this element comprising the serrated jaws and being arranged in a block in insulating material from which the teeth of the jaws, this block being covered by at least one other block of insulating material, clamping means being provided for clamping said other block on the main cable spanning the jaws, and in that both jaws are connected to each other by a strip of the cut sheet.

L'élément découpé d'une seule pièce, assure ainsi simultanément les fonctions de mâchoires venant en prise avec l'âme du câble et d'organe assurant la liaison électrique entre le ou les conducteurs.The one-piece cut element ensures thus simultaneously the jaw functions coming in taken with the core of the cable and of the body ensuring the electrical connection between the conductor (s).

Il en résulte une simplification de la fabrication et une augmentation de la fiabilité des connexions électriques, du fait de la réduction du nombre de pièces et du nombre de contacts électriques.This results in a simplification of the manufacturing and increased reliability of electrical connections, due to the reduction in number of parts and number of electrical contacts.

De plus les deux mâchoires reliées électriquement entre elles, assurent une excellente connexion électrique avec l'âme du câble principal.In addition the two connected jaws electrically between them, provide excellent electrical connection with the core of the main cable.

De préférence, chaque mâchoire venant en prise avec le câble principal comprend deux séries parallèles de dents.Preferably, each jaw engaging with the main cable includes two parallel series teeth.

Ces deux séries de dents permettent d'améliorer la connexion électrique.These two sets of teeth improve the electrical connection.

Suivant plusieurs possibilités de l'invention, le courant électrique issu du câble principal peut être transmis, soit à une barre conductrice par une plage boulonnée plate, soit par des parties dentelées de la pièce découpée sur la même plaque métallique, formée en mâchoire, qui permettent de serrer des câbles secondaires de dérivation.According to several possibilities of the invention, the electric current from the main cable can be transmitted, either to a busbar by a track bolted flat, either by serrated parts of the piece cut from the same metal plate, formed in jaws, which allow cables to be clamped secondary derivation.

Un trou supplémentaire est prévu dans la pièce découpée, à un endroit accessible, pour permettre le raccordement avec une cosse boulonnée, d'un câble volant pour branchement provisoire ou réalimentation.An additional hole is provided in the room cut in an accessible location to allow connection with a bolted terminal, a flying cable for temporary connection or recharge.

Dans les figures 9, 10 et 11, un trou supplémentaire 32 est également figuré pour raccorder par boulonnage la cosse d'un câble de branchement provisoire ou de réalimentation. Ce trou peut également être avantageusement placé en 32a, pour permettre une meilleure accessibilité, et faciliter le raccordement provisoire. Les trous 38 servent pour le passage d'un boulon de serrage des mâchoires.In Figures 9, 10 and 11, a hole additional 32 is also shown to connect by bolting the terminal of a connection cable temporary or recharge. This hole can also advantageously be placed in 32a, to allow a better accessibility, and easier connection provisional. The holes 38 are used for the passage of a jaw tightening bolt.

Un trou 32a est placé sur le dessus, sur la partie 26 de l'élément découpé.Figure 12 shows a variant of the Figure 10 in a direct link version with a barre, via a flat beach Bolt-. A hole 32a is placed on the top, on the part 26 of the cut element.

Dans la réalisation des figures 1 à 4, le dispositif représenté permet de raccorder électriquement un câble 1, principal, (voir figure 2) avec une connexion rigide constituée par une barre conductrice 33 serrée avec un boulon 34 sur l'élément métallique 10.In the embodiment of FIGS. 1 to 4, the shown device allows electrical connection a cable 1, main, (see Figure 2) with a rigid connection consisting of a busbar 33 tightened with a bolt 34 on the metal element 10.

Dans la réalisation des figures 5 à 7, le dispositif représenté permet de raccorder électriquement un câble principal 1 avec un ou plusieurs câbles 2 secondaires (voir figures 6 et 7). L'âme de ces câbles peut être constituée par un conducteur massif ou par un certain nombre de fils métalliques 4 entourés par une gaine isolante 5. Ces câbles 1, 2 sont serrés contre au moins une mâchoire 6, 7 dentelée dont les dents 8, 9 traversent la gaine isolante 5 et sont en contact avec l'âme 4.In the embodiment of FIGS. 5 to 7, the shown device allows electrical connection a main cable 1 with one or more cables 2 secondary (see Figures 6 and 7). The soul of these cables can be formed by a solid conductor or by a number of metallic wires 4 surrounded by a insulating sheath 5. These cables 1, 2 are clamped against at minus a serrated jaw 6, 7 of which the teeth 8, 9 pass through the insulating sheath 5 and are in contact with soul 4.

Conformément à l'invention, le dispositif comprend un élément métallique 10 réalisé d'une seule pièce par découpage et pliage d'une tôle en métal conducteur (voir figures 1, 3, 4, 5, 8 et 9).According to the invention, the device includes a metal element 10 made in one part by cutting and bending a metal sheet conductor (see Figures 1, 3, 4, 5, 8 and 9).

Cet élément 10 comporte plusieurs mâchoires dentelées 6, 6a, 7 espacées, et est disposé dans un bloc 11 en matière isolante duquel font saillie les dents 8, 9 des mâchoires 6, 6a, 7. Le bloc 11 ci-dessus est recouvert par un ou plusieurs autres blocs 12, 13 en matière isolante. Des moyens de serrage tels que des vis 14, 15 sont prévus pour serrer les blocs sur les câbles 1, 2 s'étendant sur les mâchoires 6, 7.This element 10 has several jaws serrated 6, 6a, 7 spaced apart, and is arranged in a block 11 in insulating material from which the teeth 8 protrude, 9 of jaws 6, 6a, 7. Block 11 above is covered by one or more other blocks 12, 13 in insulating material. Clamping means such as screws 14, 15 are provided to tighten the blocks on the cables 1, 2 extending over the jaws 6, 7.

On voit sur les figures 2 et 6 que pour le câble principal 1, l'élément métallique 10 comprend une seconde mâchoire dentelée 6a, dont les dents 8 sont situées en regard des dents 8 de la première mâchoire 6. Ces deux mâchoires 6, 6a sont reliées l'une à l'autre par une bande 16 de la tôle découpée avantageusement de forme arquée.We see in Figures 2 and 6 that for the cable main 1, the metallic element 10 comprises a second serrated jaw 6a, the teeth 8 of which are located opposite the teeth 8 of the first jaw 6. These two jaws 6, 6a are connected to each other by a strip 16 of the sheet metal cut advantageously from arched shape.

Cette bande de tôle découpée peut également être de forme non arquée comme montré à la figure 10.This strip of cut sheet metal can also be non-arched shape as shown in Figure 10.

On voit d'autre part sur les figures 1 et 5, que chaque mâchoire 6, 6a destinée à venir en prise avec le câble principal 1 comprend deux séries parallèles de dents 8.We see on the other hand in Figures 1 and 5, that each jaw 6, 6a intended to come into engagement with the main cable 1 includes two parallel series of teeth 8.

De plus, dans ces exemples, l'élément métallique 10 comprend quatre mâchoires 6, 6a venant en prise avec le câble principal 1, deux d'entre elles 6 étant situées dans un premier plan et les deux autres 6a dans un plan parallèle au premier. L'espace compris entre les deux paires de mâchoires permet l'insertion du câble 1.In addition, in these examples, the metallic element 10 includes four jaws 6, 6a engaging with the main cable 1, two of them 6 being located in the foreground and the other two 6a in the foreground parallel to the first. The space between the two pairs of jaws allows cable insertion 1.

Les deux mâchoires 6 situées dans le premier plan comprennent une première série de dents 8 situées dans le plan d'une bande longitudinale 17 et une seconde série de dents 8 situées dans le plan d'une portion de bande 18 parallèle à la bande longitudinale 17 et reliée à cette dernière par une bande transversale 19.The two jaws 6 located in the first plan include a first set of teeth 8 located in the plane of a longitudinal strip 17 and a second series of teeth 8 located in the plane of a portion of strip 18 parallel to the longitudinal strip 17 and connected to the latter by a transverse strip 19.

Par ailleurs, les deux mâchoires 6a situées dans le second plan comprennent deux séries de dents 8 situées chacune dans le plan d'une portion de bande 20. Les deux portions de bande 20 sont reliées d'une part par une bande transversale 21 et d'autre part par la bande arquée 16 qui relie chacune de ces mâchoires 6a à chacune des mâchoires 6 situées dans le premier plan.Furthermore, the two jaws 6a located in the second plan include two sets of teeth 8 each located in the plane of a portion of strip 20. The two strip portions 20 are connected on the one hand by a transverse strip 21 and on the other hand by the arcuate strip 16 which connects each of these jaws 6a to each of the jaws 6 located in the foreground.

Dans le cas des figures 1 à 3, de la bande transversale 16a qui relie les deux bandes 16, est issue une bande longitudinale munie d'un trou rond 32 qui permet de réaliser la liaison électrique avec une barre 33 par boulonnage.In the case of FIGS. 1 to 3, of the strip transverse 16a which connects the two strips 16, comes from a longitudinal strip provided with a round hole 32 which allows to make the electrical connection with a bar 33 by bolting.

Dans le cas de la figure 4, une seule bande 16 relie entre elles les mâchoires dentelées.In the case of FIG. 4, a single strip 16 connects the serrated jaws together.

D'autre part, dans le cas des figures 5 à 8, chaque bande longitudinale 17 porte à une certaine distance de la mâchoire 6 venant en prise avec le câble principal 1, une mâchoire 7 venant en prise avec un câble 2 secondaire s'étendant dans la direction d'allongement de la bande longitudinale 17.On the other hand, in the case of FIGS. 5 to 8, each longitudinal strip 17 carries to a certain distance from jaw 6 engaging with cable main 1, a jaw 7 engaging with a secondary 2 cable extending in the direction elongation of the longitudinal strip 17.

Dans le cas de la figure 9, les mâchoires 17 sont issues d'autres zones de l'élément conducteur en fonction des possibilités de la découpe et de la localisation choisie des câbles après pliage de cet élément conducteur.In the case of FIG. 9, the jaws 17 come from other areas of the conductive element in depending on the possibilities of cutting and chosen location of cables after folding this conductive element.

En outre, dans le cas des figures 5 à 8, la mâchoire 7 venant en prise avec un câble 2 secondaire est ménagée sur une extrémité ondulée 17a de la bande longitudinale 17.Furthermore, in the case of FIGS. 5 to 8, the jaw 7 engaging with a secondary cable 2 is formed on a corrugated end 17a of the strip longitudinal 17.

Comme indiqué sur les figures 6 et 7, les bandes longitudinales 17 et les portions de bandes 18, 20, sont logées dans des fentes pratiquées dans les blocs 11, 12, 13, serrés l'un contre l'autre.As shown in Figures 6 and 7, the bands longitudinal 17 and the strip portions 18, 20 are housed in slots made in blocks 11, 12, 13, pressed against each other.

Ces fentes maintiennent parfaitement l'élément 10 dans les blocs isolants 11, 12, 13.These slots hold the element perfectly 10 in the insulating blocks 11, 12, 13.

Les figures 8 et 9 représentent en plan l'élément 10 découpé dans une tôle en métal ou alliage bon conducteur de l'électricité.Figures 8 and 9 show in plan element 10 cut from a metal or alloy sheet good conductor of electricity.

Pour obtenir l'élément 10 tel que représenté sur la figure 1, il suffit de replier à angle droit les bandes longitudinales 17 et les portions de bandes 18, 20, puis d'onduler l'extrémité des parties 17 dans le cas des figures 5 à 9, puis de plier en arc les bandes 16.To obtain element 10 as shown in Figure 1, just fold the right angles longitudinal strips 17 and the strip portions 18, 20, then to wave the end of the parts 17 in the case of figures 5 to 9, then bend the strips in an arc 16.

La figure 10 représente une autre version de réalisation d'un élément découpé dans une tôle.Figure 10 shows another version of production of an element cut from a sheet.

Dans cette version, l'élément 10a comprend à l'une de ses extrémités deux séries de dents parallèles 8a perpendiculaires à une bande 25 qui est prolongée par une bande 26 repliée vers les deux séries de dents 8a ci-dessus.In this version, element 10a includes one of its ends two sets of parallel teeth 8a perpendicular to a strip 25 which is extended by a band 26 folded towards the two sets of teeth 8a above.

Cette bande 26 repliée est elle-même bordée par des dents 8a disposées en regard des deux séries de dents 8a précitées.This folded strip 26 is itself bordered by teeth 8a arranged opposite the two series of teeth 8a above.

Par ailleurs, la bande 25 est prolongée par une partie élargie 27 dans laquelle sont découpées latéralement des lames 28, 29, 30 portant chacune deux séries de dents 9a pliées perpendiculairement à ces lames.Furthermore, the strip 25 is extended by a widened part 27 in which are cut laterally blades 28, 29, 30 each carrying two series of teeth 9a bent perpendicular to these blades.

La figure 11 représente une vue de dessus d'un module isolant 36 de raccordement de câbles, réalisé à partir de l'élément découpé 10a représenté sur la figure 10. Ce module permet de raccorder un câble principal 1 à trois câbles secondaires. Un bouchon isolant 37 protège l'accès au trou 32.Figure 11 shows a top view of a insulating module 36 for cable connection, made at starting from the cut element 10a shown in the figure 10. This module allows you to connect a main cable 1 to three secondary cables. An insulating cap 37 protects access to hole 32.

Bien entendu l'invention n'est pas limitée aux exemples de réalisation que l'on vient de décrire et on peut apporter à ceux-ci de nombreuses modifications sans sortir du cadre de l'invention tel que défini par les revendications.Of course, the invention is not limited to examples of realization that we have just described and we can make many changes to them without depart from the scope of the invention as defined by the claims.
