Abstract

The contacts are crimped and riveted to the common cable, which remains flexible. The flexible connection includes a flexible cable or wire (1) to which connection tongues (2) are attached at regular intervals. The cable is preferably made from a multi-strand braid. The tongues, which are electrically conductive, each include a rectilinear section (3) which may be inserted into a modular electrical appts., and a folded section (4) which is wrapped around the flexible cable. The tongues may be cut from a sheet of metal such as copper. The folded section is attached to the conducting cable by crimping around the cable. This may be retained by the use of a reduced section end on the tongue which then fits back through an aperture formed in the folded section near to the point where this joins the straight section. After insertion through the aperture, the end may be enlarged to form a rivet-type fastening.

Description

La présente invention concerne un dispositif de raccordement essentiellement constitué de languettes fixées à intervalles réguliers à au moins une âme conductrice logée dans une enveloppe isolante, lesdites languettes dépassant de l'enveloppe en vue de leur connexion à des bornes électriques.The present invention relates to a connection device essentially consisting of tabs fixed at regular intervals with at least one conductive core housed in an envelope insulating, said tabs protruding from the envelope for their connection to electrical terminals.

Selon un exemple préférentiel, qui ne constitue cependant pas la seule application possible de l'invention, le dispositif de raccordement peut être connecté à des appareils électriques modulaires fixés côte à côte sur un rail support standard, et il fait alors office de barre de pontage.According to a preferred example, which does not however constitute the only possible application of the invention, the connection can be connected to electrical devices modular fixed side by side on a standard support rail, and it makes then as a bypass bar.

Selon l'objectif principal de l'invention, ladite barre de pontage ou plus généralement le dispositif de raccordement est flexible et élastique, et fabriqué par exemple sous la forme d'une barre continue que l'on sectionne à la longueur désirée pour l'application qui en est faite. Dans ce cas, elle peut facilement être stockée sur un rouleau, et déroulée à mesure que l'on veut en sectionner des tronçons.According to the main objective of the invention, said bridging bar or more generally the connection device is flexible and elastic, and made for example in the form of a bar continue cutting to the desired length for the application made of it. In this case, it can easily be stored on a roll, and unwound as you want to cut some sections.

Selon un autre objectif possible, l'invention peut être fabriquée sous forme de tronçons de longueurs précises, correspondant par exemple à la largeur des armoires électriques ou des montages que l'on veut installer.According to another possible objective, the invention can be manufactured in the form of sections of precise lengths, corresponding by example to the width of electrical cabinets or fixtures that we want to install.

Lorsque le dispositif de raccordement est mis en oeuvre avec des appareils modulaires classiques, les propriétés mécaniques mentionnées auparavant permettent d'assurer une compatibilité entre appareils modulaires dotés de niveaux de pontage différents, comme des appareils issus de fabrications différentes, ou des appareils issus de gammes échelonnées dans le temps.When the connection device is used with classic modular devices, mechanical properties mentioned above ensure compatibility between modular devices with different bridging levels, such as devices from different manufacturers, or devices from ranges staggered in time.

De même, en application avec ces appareils, il permet de réaliser ce qu'il est convenu d'appeler la démontabilité haute, dont on rappelle ci-après la problématique. Les appareils électriques modulaires comportent un boítier isolant fixable à un rail support profilé normalisé.Similarly, in application with these devices, it makes it possible to achieve what it agreed to call the high dismountability, which we recall below problematic. Modular electrical devices have a housing insulating material which can be fixed to a standardized profile support rail.

Ledit boítier comporte à cet effet un socle doté d'un évidement d'allure longitudinale limité à ses extrémités d'une part par une encoche et d'autre part par un loquet de verrouillage, permettant la fixation du boítier aux rebords du rail. La démontabilité doit s'effectuer par rapport à un dispositif surmontant les appareils agencés sur leur rail.Said housing for this purpose comprises a base with a recess of shape longitudinal limited at its ends on the one hand by a notch and on the other hand by a locking latch, allowing the housing to be fixed to the edges of the rail. Disassembly must be carried out in relation to a device overcoming the devices arranged on their rail.

Les languettes du dispositif de raccordement faisant alors office de peigne de pontage sont donc prévues pour être raccordées aux bornes des appareils modulaires situées du même côté que l'encoche, à l'opposé par conséquent du loquet coulissable.The tabs of the connection device then acting as a comb are therefore intended to be connected to the terminals of the devices modules located on the same side as the notch, therefore opposite sliding latch.

Bien qu'il ne soit ici question que de démontabilité, il est clair que tout ceci s'applique également au montage des appareils.Although it is only a question of dismantling, it is clear that all this also applies to the mounting of devices.

Dans ce cadre, lorsqu'un peigne de pontage est fixé à une rangée d'appareils modulaires, le démontage de l'un seulement de ces appareils nécessite en principe que le peigne soit enlevé, sauf lorsque la semelle est équipée d'un dispositif particulier d'escamotage de l'encoche. Dans le premier cas, retirer le peigne impose d'ouvrir toutes les bornes de connexion qui lui sont fixées, ce qui conduit à perdre un temps considérable pour le démontage d'un unique appareil.In this context, when a bridging comb is attached to a row modular devices, disassembly of only one of these devices in principle requires that the comb be removed, except when the sole is equipped with a special device for retracting the notch. In the first In this case, removing the comb requires opening all the connection terminals which are fixed, which leads to wasting considerable time for disassembly of a single device.

Dans le second cas, le socle de l'appareil peut comporter par exemple un second loquet coulissable pour que l'appareil puisse être déplacé dans une direction parallèle à l'axe de sa semelle d'une course suffisante pour que la languette du peigne soit extraite de la borne, rendant possible le démontage individuel dudit appareil. L'adjonction d'un second loquet implique évidemment de multiples changements dans la conception de l'appareil, qui pèsent lourd en terme de process industriel et aboutissent généralement à augmenter le coût des produits. Une telle solution ne s'applique de plus que pour les appareils fabriqués d'office avec un second loquet, qui ne peut de toute évidence pas équiper a posteriori des appareils issus de gammes plus anciennes.In the second case, the base of the device may for example include a second sliding latch so that the device can be moved in a direction parallel to the axis of its sole with a stroke sufficient for the comb tongue is extracted from the terminal, making disassembly possible individual of said device. The addition of a second latch implies obviously multiple changes in the design of the device, which weigh heavily in terms of industrial process and generally result in increase the cost of products. Such a solution only applies more than for devices produced automatically with a second latch, which cannot obviously not retrofit devices from more ranges old.

Pour répondre au problème de l'extraction individuelle tel que posé ci-dessus, une alternative possible consiste à modifier non pas les appareils modulaires, mais le peigne de pontage lui-même : c'est la perspective permise par le dispositif de raccordement de l'invention, dont les caractéristiques précitées autorisent le montage / démontage individuel des appareils modulaires.To answer the problem of individual extraction as posed above, a possible alternative is to modify not the devices modular, but the bridging comb itself: it's perspective allowed by the connection device of the invention, the characteristics of which above authorize the individual assembly / disassembly of the devices modular.

Pour réaliser les objectifs et fonctionnalités précités, le dispositif de raccordement de l'invention est principalement caractérisé en ce que la ou les âmes conductrices et l'enveloppe isolante sont constitués d'un matériau flexible, la position relative des languettes, de la ou des âmes et de l'enveloppe isolante étant fixée de manière uniforme sur la totalité de la longueur du dispositif par l'enveloppe isolante de façon à former une structure continue flexible et élastique de longueur quelconque présentant une périodicité spatiale égale à l'entraxe de deux languettes consécutives.To achieve the above objectives and functionalities, the connection of the invention is mainly characterized in that the one or more conductive cores and the insulating jacket are made of a material flexible, the relative position of the tongues, of the core (s) and of the insulating jacket being fixed uniformly over the entire length of the device by the insulating envelope so as to form a structure continuous flexible and elastic of any length with a spatial periodicity equal to the distance between two consecutive tabs.

En d'autres termes, sur une longueur indéfinie, une structure souple entoure au moins une âme conductrice d'allure axiale sur laquelle sont fixées périodiquement des languettes de connexion.In other words, over an indefinite length, a flexible structure surrounds at least one conductive core of axial shape on which are fixed periodically connecting tabs.

Il suffit de sectionner des tronçons de longueur appropriée à l'utilisation ultérieure pour obtenir par exemple des barres de pontage flexibles permettant d'assurer la compatibilité entre appareils dotés de niveaux de pontage différents, et autorisant de surcroít la démontabilité haute.Just cut sections of appropriate length for the use for example to obtain flexible bridging bars allowing ensure compatibility between devices with bridging levels different, and in addition allowing high dismountability.

Plus précisément, l'enveloppe isolante consiste en un enrobage isolant flexible et élastique entourant le ou les âmes conductrices et une portion des languettes qui y sont fixées.More specifically, the insulating envelope consists of an insulating coating flexible and elastic surrounding the conductive core (s) and a portion of the tabs attached to it.

L'élasticité, qui n'est pas requise pour par exemple le stockage en bobines, est en revanche strictement nécessaire pour assurer la démontabilité haute, ainsi que la compatibilité entre appareils dotés de niveaux de pontage non uniformes.Elasticity, which is not required for, for example, storage in reels, on the other hand is strictly necessary to ensure high dismountability, as well as compatibility between devices with non-bridging levels uniforms.

De préférence, ledit enrobage isolant est réalisé par surmoulage de matière plastique flexible et élastique autour de la structure constituée de l'âme ou des âmes conductrices munie(s) des languettes.Preferably, said insulating coating is produced by overmolding of material flexible and elastic plastic around the structure consisting of the core or conductive cores fitted with tabs.

Le surmoulage aboutit à "noyer" les composants internes (âmes conductrices, portions internes des languettes), à maintenir leur fixation et à revenir à leur positionnement relatif après déformation, quelles que soient les contraintes exercées sur le dispositif de raccordement de l'invention.Overmolding results in "drowning" the internal components (cores conductive, internal portions of the tabs), to maintain their fixing and to return to their relative positioning after deformation, whatever the stresses exerted on the connection device of the invention.

Pour que les fonctions nécessitant un déplacement élastique de la structure puissent être mises en oeuvre, il convient que l'enrobage isolant présente une élasticité autorisant le déplacement transversal d'une languette lorsque les deux languettes adjacentes sont bloquées.So that the functions requiring an elastic displacement of the structure can be implemented, the insulating coating should have a elasticity allowing transverse displacement of a tongue when the two adjacent tabs are locked.

Selon une possibilité, chaque âme conductrice est constituée d'une tresse multibrin en métal conducteur.According to one possibility, each conductive core consists of a braid conductive metal strand.

L'exigence de flexibilité s'accommode bien entendu également d'autres configurations de l'âme conductrice, que l'on peut mettre en oeuvre dans le cadre de l'invention. La tresse multibrin présente toutefois de nombreux avantages : elle est notamment facile à adapter à l'ampérage, et facilite la fixation des languettes.The flexibility requirement naturally also accommodates other configurations of the conductive core, which can be implemented in the part of the invention. The multi-strand braid, however, has many advantages: it is particularly easy to adapt to the amperage, and facilitates the fixing the tabs.

Ces dernières sont de préférence constituées de lamelles métalliques soudées ou serties à l'âme ou aux âmes conductrice(s) souple(s). Elles sont par exemple réalisées par découpe dans des feuillards conducteurs et elles présentent, pour un dispositif de l'invention donné, une géométrie et des dimensions identiques.The latter are preferably made of metal strips soldered or crimped to the flexible conductive core (s). They are for example produced by cutting from conductive strips and they have, for a given device of the invention, a geometry and identical dimensions.

Ces languettes, selon l'application qui est faite dudit dispositif, par exemple sous la forme d'un peigne de pontage, peuvent être sectionnées en sortie de l'isolant, notamment lorsque ledit peigne est appliqué à un appareil double dépourvu de deux bornes de connexion adjacentes sur ses petites faces (disjoncteur différentiel...).These tabs, depending on the application which is made of said device, for example in the form of a bridging comb, can be sectioned at the outlet of the insulator, in particular when said comb is applied to a double device without two adjacent connection terminals on its small faces (differential circuit breaker ...).

Selon une configuration possible, chaque lamelle métallique est dotée d'une extrémité de largeur réduite prévue pour être insérée dans une lumière pratiquée dans le corps de la lamelle après repliage en boucle de ladite extrémité autour d'une âme conductrice, la partie de ladite extrémité qui dépasse de la lumière étant ensuite élargie pour fixer la boucle.Depending on a possible configuration, each metal strip has of a reduced width end intended to be inserted into a lumen practiced in the body of the coverslip after folding in a loop of said end around a conductive core, the part of said end which protrudes from the light then being widened to secure the loop.

L'élargissement de l'extrémité libre de plus petite largeur, permettant de verrouiller la boucle, est réalisé par des moyens classiques du type martelage.The widening of the free end of smaller width, allowing locking the loop is achieved by conventional means of the hammering type.

Selon une possibilité, chaque lamelle est soudée à deux tresses multibrins.According to one possibility, each strip is welded to two multi-strand braids.

Une configuration à deux âmes distinctes peut notamment être justifiée par l'intensité du courant prévu pour être véhiculé dans le dispositif de raccordement de l'invention. De multiples autres configurations sont bien entendu réalisables, y compris avec des rangées de lamelles distinctes, si le besoin s'en fait jour. A configuration with two distinct cores can in particular be justified by the intensity of the current expected to be conveyed in the device connection of the invention. Multiple other configurations are fine heard feasible, including with separate rows of slats, if the need arises.

L'invention va à présent être décrite plus en détail, en référence aux figures annexées, pour lesquelles :

  • la figure 1 représente une vue en perspective d'un conducteur souple auquel sont fixées des languettes ;
  • la figure 2 est une vue en section transversale de l'ensemble représenté en figure 1;
  • la figure 3 montre une vue en perspective d'une languette ;
  • la figure 4 illustre une variante à deux tresses de l'invention ;
  • la figure 5 est une vue en perspective de la seconde variante avec l'enrobage isolant ; et
  • la figure 6 montre une vue de dessus partielle d'appareils modulaires équipés d'une barre de pontage selon l'invention.
The invention will now be described in more detail, with reference to the appended figures, for which:
  • Figure 1 shows a perspective view of a flexible conductor to which are fixed tabs;
  • Figure 2 is a cross-sectional view of the assembly shown in Figure 1;
  • Figure 3 shows a perspective view of a tongue;
  • FIG. 4 illustrates a variant with two braids of the invention;
  • Figure 5 is a perspective view of the second variant with the insulating coating; and
  • Figure 6 shows a partial top view of modular devices equipped with a bridging bar according to the invention.

La figure 1 illustre en fait le coeur de l'invention : au moins un câble ou fil conducteur souple (1) sur lequel sont fixés, à intervalles réguliers, des languettes de connexion (2). De préférence, ledit fil souple (1) est constitué d'une tresse multibrin.FIG. 1 in fact illustrates the heart of the invention: at least one cable or wire flexible conductor (1) on which are fixed, at regular intervals, connection tabs (2). Preferably, said flexible wire (1) consists of a multi-strand braid.

Lesdites languettes (2), également conductrices, sont composées d'une partie rectiligne (3) destinée à être insérée dans la borne de connexion par exemple d'un appareil électrique modulaire, et d'une partie repliée (4), lieu de la fixation au fil (1)). A l'origine, ces languettes (2) sont réalisées à partir de barrettes découpées dans un feuillard en matériau conducteur, par exemple du cuivre.Said tabs (2), also conductive, are composed of a rectilinear part (3) intended to be inserted into the connection terminal by example of a modular electrical appliance, and of a folded part (4), instead of attachment to the wire (1)). Originally, these tongues (2) are made from strips cut from a strip of conductive material, for example copper.

La fixation de ces languettes (2) au câble conducteur (1) apparaít particulièrement bien en figure 2. Dans ce cas, une fixation par sertissage de la languette (2) autour du fil (1) a été choisie, ledit sertissage étant réalisé par repliage et serrage de l'extrémité (4) de la barrette. Ledit serrage est rendu possible par la configuration particulière de la languette, qui apparaít plus clairement en figure 3 : l'extrémité (5) de la partie repliée (4) présente une largeur réduite, conférant à cette extrémité (5) une section apte à s'introduire dans une lumière (6) pratiquée dans la languette (2), dans le début de la portion repliée (4).The attachment of these tabs (2) to the conductor cable (1) appears particularly well in FIG. 2. In this case, fixing by crimping the tongue (2) around the wire (1) has been chosen, said crimping being carried out by folding and tightening of the end (4) of the bar. Said tightening is rendered possible by the particular configuration of the tongue, which appears more clearly in Figure 3: the end (5) of the folded part (4) has a reduced width, giving this end (5) a section capable of being introduced in a lumen (6) formed in the tongue (2), in the beginning of the folded portion (4).

La longueur de l'extrémité (5) de section réduite est prévue de telle sorte qu'un serrage puisse s'exercer sur la tresse (1) (voir figure 2), et que le bout de cette partie, dépassant de la lumière (6), puisse être élargi par exemple par martelage pour bloquer la liaison. The length of the end (5) of reduced section is provided so that that a tightening can be exerted on the braid (1) (see figure 2), and that the end of this part, protruding from the light (6), can be widened for example by hammering to block the connection.

La figure 4 montre une variante à deux tresses (1, 1') sur lesquelles sont soudées les languettes (2). Dans ce cas, la portion (7) des languettes sur laquelle les tresses (1, 1') sont fixées est d'allure plane, décalée par rapport à la portion rectiligne (3) de la languette, et de surface suffisante pour recevoir deux portions compactées (8) des tresses (1, 1').Figure 4 shows a variant with two braids (1, 1 ') on which are welded the tabs (2). In this case, the portion (7) of the tabs on which the braids (1, 1 ') are fixed has a planar appearance, offset from the straight portion (3) of the tongue, and of sufficient area to receive two compacted portions (8) of the braids (1, 1 ').

En référence à la figure 5, l'ensemble conducteur décrit à la figure précédente est enrobé dans un matériau isolant souple (9) formant une structure flexible dont dépassent les languettes (2).Referring to Figure 5, the conductor assembly described in Figure above is coated with a flexible insulating material (9) forming a flexible structure with protruding tabs (2).

Un peigne de pontage réalisé selon cette variante peut être fabriqué en des longueurs prédéterminées. Dans ce cas, les extrémités latérales sont revêtues d'une couche isolante protégeant l'extrémité de la tresse conductrice (1). Parmi les longueurs intéressantes, on peut citer celles qui correspondent à la largeur d'un coffret ou d'une armoire.A bridging comb produced according to this variant can be manufactured in predetermined lengths. In this case, the side ends are coated an insulating layer protecting the end of the conductive braid (1). Among the interesting lengths, we can cite those which correspond to the width of a box or cupboard.

Selon une alternative possible, la structure de la figure 5 peut être fabriquée au mètre ou au rouleau et coupée à la longueur voulue par l'utilisateur, sur et en fonction des besoins du site. Dans ce cas, la ou les tresses conductrices (1) affleurent les extrémités sectionnées, et il est nécessaire de prévoir un bouchon de protection (non représenté). Ce mode de fabrication, outre sa très grande commodité, offre l'avantage de ne pas constituer de chute : seule la quantité strictement nécessaire à la réalisation du peigne est sectionnée. La configuration de dispositif de raccordement montrée dans cette figure peut de plus être stockée sur des rouleaux ou bobines, ce qui constitue un autre avantage déterminant.According to a possible alternative, the structure of FIG. 5 can be manufactured by the meter or the roll and cut to the desired length by the user, on and according to the needs of the site. In this case, the conductive braids (1) are flush with the severed ends, and it is necessary to provide a protective cap (not shown). This mode of manufacturing, in addition to its great convenience, offers the advantage of not constitute of fall: only the quantity strictly necessary for the realization of the comb is sectioned. The connection device configuration shown in this figure can also be stored on rolls or reels, which is another defining advantage.

La fabrication de cette configuration peut se faire par moulage par injection de matière plastique isolante.The manufacturing of this configuration can be done by injection molding of insulating plastic.

En figure 6, on a représenté une rangée d'appareils modulaires (10) fixés sur un rail normalisé (11), l'un de ces appareils modulaires (10) étant en cours de montage / démontage, et donc décalé latéralement par rapport aux autres.In Figure 6, there is shown a row of modular devices (10) fixed on a standardized rail (11), one of these modular devices (10) being in progress mounting / dismounting, and therefore laterally offset from the others.

La barre de pontage de l'invention est fixée, via les languettes (2) dans les bornes de connexion des appareils (10) contigus à celui que l'on extrait / insère, mais l'élasticité et la flexibilité du dispositif de l'invention permettent cependant la déformation de ladite barre au niveau de l'appareil (10) à extraire / insérer. Cette déformation implique bien entendu que la ou les tresses (1, 1') aient une longueur suffisante, entre deux languettes (2), pour absorber ladite déformation. The bridging bar of the invention is fixed, via the tabs (2) in the terminals for connecting the devices (10) contiguous to that which is extracts / inserts, but the elasticity and flexibility of the device of the invention however allow the deformation of said bar at the device (10) to extract / insert. This deformation obviously implies that the braids (1, 1 ') have a sufficient length, between two tabs (2), to absorb said deformation.

C'est la raison pour laquelle dans les figures précédentes, les tresses (1, 1') sont toujours représentées non tendues, afin de garder une longueur résiduelle aux fins précitées.This is the reason why in the previous figures, the braids (1, 1 ') are always shown unstretched, in order to keep a length residual for the above purposes.

Les variantes illustrées précédemment ne constituent bien entendu que des exemples non exhaustifs de l'invention. Celle-ci englobe au contraire toute variante de forme, configuration, matière, etc... à la portée de l'homme de l'art.The variants illustrated above are of course only non-exhaustive examples of the invention. On the contrary, it includes all variant of shape, configuration, material, etc ... within the reach of ordinary skill in the art.
