Description

La présente invention concerne les connecteurs utilisés pour assurer une connexion entre les conducteurs prévus dans deux câbles à raccorder.The present invention relates to the connectors used to ensure a connection between the conductors provided in two cables to be connected.

Pour faciliter une telle connexion, et notamment pour éviter d'avoir à dénuder les extrémités des conducteurs correspondants, il a déjà été proposé des connecteurs comportant des lames mobiles de connexion qui sont susceptibles d'être enfoncées dans la gaine isolante des cables à raccorder afin de venir en contact avec les conducteurs enrobés par cette gaine.To facilitate such a connection, and in particular to avoid having to strip the ends of the corresponding conductors, connectors have already been proposed comprising movable connection blades which are capable of being pressed into the insulating sheath of the cables to be connected in order to come into contact with the conductors coated by this sheath.

Ainsi le document FR.A.2.482.790 a pour objet un connecteur dont le corps isolant présente deux canaux aptes à recevoir les câbles à raccorder et comporte, en regard de l'un et l'autre bords de ces canaux, deux lames métalliques mobiles de connexion. Ce connecteur est destiné à recevoir deux câbles plats renfermant chacun deux conducteurs disposés près de l'un et l'autre bords. Ainsi lorsque les extrémités de tels câbles sont placées dans les canaux du corps de ce connecteur, chacune des lames mobiles de connexion se trouve disposée en regard de l'un des conducteurs de l'un et l'autre câbles. Or, ce connecteur comporte un capuchon apte à exercer une pression sur les lames mobiles de connexion lors de sa mise en place, de façon que ces lames soient enfoncées dans la gaine isolante de l'un et l'autre câbles pour venir en contact direct avec les conducteurs correspondants. A cet effet, la paroi interne de ce capuchon présente une forme conique et sa fixation sur le corps du connecteur est assurée par vissage, ce qui permet d'exercer ainsi une forte pression sur les lames mobiles de connexion.Thus the document FR.A.2.482.790 relates to a connector whose insulating body has two channels capable of receiving the cables to be connected and comprises, opposite one and the other edges of these channels, two metal blades connection mobiles. This connector is intended to receive two flat cables each containing two conductors arranged near one and the other edges. Thus when the ends of such cables are placed in the channels of the body of this connector, each of the movable connection blades is arranged opposite one of the conductors of one and the other cables. However, this connector includes a cap capable of exerting pressure on the movable connection blades during its installation, so that these blades are pressed into the insulating sheath of both cables to come into direct contact. with the corresponding conductors. For this purpose, the internal wall of this cap has a conical shape and its fixing to the body of the connector is ensured by screwing, which thus allows to exert a strong pressure on the movable connection blades.

Cependant, ce connecteur ne peut convenir que pour un type déterminé de câble électrique, car la section des canaux du corps isolant doit correspondre à celle des câbles à raccorder. Ainsi, si le connecteur est conçu pour recevoir des câbles plats comportant deux conducteurs disposés de part et d'autre d'une âme métallique axiale, il ne peut pas convenir pour raccorder des câbles moins larges dépourvus d'une telle âme axiale. A plus forte raison, ce connecteur ne peut pas être utilisé pour assurer la connexion de conducteurs indépendants. Or, dans de nombreux cas, il y a lieu de raccorder de tels conducteurs faisant partie d'un faisceau de conducteurs.However, this connector can only be suitable for a specific type of electrical cable, because the section of the channels of the insulating body must correspond to that of the cables to be connected. Thus, if the connector is designed to receive flat cables comprising two conductors disposed on either side of an axial metal core, it cannot be suitable for connecting narrower cables devoid of such an axial core. A fortiori, this connector cannot be used to ensure the connection of independent conductors. However, in many cases, it is necessary to connect such conductors forming part of a bundle of conductors.

C'est pourquoi la présente invention a pour but de réaliser un connecteur polyvalent susceptible d'être utilisé pour le raccordement de différents types de câbles ou de conducteurs. Cependant, l'invention a également pour but de réaliser un certain nombre de perfectionnements sur un tel connecteur.This is why the present invention aims to provide a versatile connector capable of being used for the connection of different types of cables or conductors. However, the invention also aims to achieve a number of improvements on such a connector.

A cet effet, elle a pour objet un connecteur pour la connexion de câbles électriques plats comprenant chacun deux conducteurs enrobés dans une gaine isolante, lequel comprend un corps isolant présentant deux canaux sensiblement paralléles aptes à recevoir les câbles à raccorder et deux lames métalliques de connexion montées mobiles en regard de l'un et l'autre bords de ces canaux, ainsi qu'un capuchon destiné à être rapporté sur le corps de ce connecteur pour enfoncer ces deux lames dans la gaine isolante des deux câbles afin d'assurer la connexion électrique entre les conducteurs correspondants, caractérisé en ce que dans leur fond, du côté opposé à l'introduction des câbles, ces canaux comportent une extension dont la largeur correspond à celle de câbles plats sans âme métallique axiale, cette largeur étant plus faible que celle des canaux du côté introduction des câbles, laquelle correspond à la largeur des câbles avec âme métallique axiale.To this end, it relates to a connector for the connection of flat electrical cables each comprising two conductors embedded in an insulating sheath, which comprises an insulating body having two substantially parallel channels adapted to receive the cables to be connected and two metal connection blades mounted movable opposite both edges of these channels, as well as a cap intended to be attached to the body of this connector to push these two blades into the insulating sheath of the two cables in order to ensure the connection electric between the corresponding conductors, characterized in that in their bottom, on the side opposite to the introduction of the cables, these channels have an extension whose width corresponds to that of flat cables without axial metallic core, this width being narrower than that channels on the cable entry side, which corresponds to the width of the cables with axial metallic core.

Ainsi, le présent connecteur peut être utilisé indifféremment pour assurer le raccordement de câbles plats renfermant deux conducteurs et une âme métallique axiale ou pour connecteur des câbles plats dépourvus d'une telle âme axiale.Thus, the present connector can be used interchangeably for ensuring the connection of flat cables containing two conductors and an axial metallic core or for connector of flat cables devoid of such an axial core.

Dans une forme de réalisation avantageuse, ce connecteur comprend en plus deux barrettes amovibles en matière isolante, de section similaire à celle de câbles électriques plats avec âme métallique axiale, et dont les bords présentent deux gorges susceptibles de recevoir des conducteurs électriques indépendants, ces barrettes étant susceptibles d'être placées à l'intérieur des canaux prévus dans le corps isolant de ce connecteur, de sorte que celui-ci peut être utilisé indifféremment pour la connexion de deux paires de conducteurs indépendants, placés au préalable dans les gorges de ces barrettes amovibles, ou pour la connexion de deux câbles plats avec ou sans âme métallique axiale.In an advantageous embodiment, this connector further comprises two removable strips of insulating material, of section similar to that of flat electrical cables with axial metallic core, and the edges of which have two grooves capable of receiving independent electrical conductors, these strips being likely to be placed inside the channels provided in the insulating body of this connector, so that it can be used interchangeably for the connection of two pairs of independent conductors, placed beforehand in the grooves of these bars removable, or for the connection of two flat cables with or without axial metallic core.

Le connecteur selon cette forme de réalisation peut donc être utilisé, non seulement pour la connexion des deux types usuels de câbles plats mentionnés cidessus, mais également pour le raccordement de deux paires de conducteurs distincts, et ce grâce aux barrettes amovibles supplémentaires prévues à cet effet.The connector according to this embodiment can therefore be used, not only for the connection of the two usual types of flat cables mentioned above, but also for the connection of two separate pairs of conductors, thanks to the additional removable bars provided for this purpose. .

Selon un autre caractéristique du présent connecteur, le corps isolant de celui-ci est constitué par la réunion, l'une contre l'autre, de deux parties présentant des rainures complémentaires aptes à former les deux canaux prévus dans ce corps, ces deux parties étant attachées l'une à l'autre par une languette flexible de liaison et étant pourvues de reliefs complémentaires de positionnement, par exemple des tétons et des creux correspondants. Une telle structure a l'avantage de permettre le moulage du corps de ce connecteur dans un moule de conception simple, et de faciliter l'assemblage ultérieur des diverses pièces prévues dans le corps de celui-ci.According to another characteristic of the present connector, the insulating body of the latter consists of the joining, one against the other, of two parts having complementary grooves capable of forming the two channels provided in this body, these two parts being attached to each other by a flexible connecting tab and being provided with complementary positioning reliefs, for example pins and corresponding recesses. Such a structure has the advantage of allowing the body of this connector to be molded in a mold of simple design, and of facilitating the subsequent assembly of the various parts provided in the body of the latter.

Le présent connecteur comprend deux pièces principales, à savoir un corps 1 et un capuchon 2, tous deux en matière isolante, en l'occurrence: en matière plastique moulée. Cependant le corps 1 est constitué par l'assemblage, l'une contre l'autre de deux parties identiques 3 attachées par une languette flexible 4 de liaison (voir figure 3). Sur leurs faces destinées à être accolées l'une contre l'autre, ces deux parties comportent des rainures 5 qui sont aptes à se compléter pour former, à l'intérieur du corps 1, deux canaux 6 légèrement divergents, qui sont séparés par un noyau central 7 de contour triangulaire ou trapézoïdal.The present connector comprises two main parts, namely a body 1 and a cap 2, both made of insulating material, in this case: molded plastic. However, the body 1 is constituted by the assembly, one against the other of two identical parts 3 attached by a flexible connecting tab 4 (see FIG. 3). On their faces intended to be joined against each other, these two parts have grooves 5 which are able to complement each other to form, inside the body 1, two slightly divergent channels 6, which are separated by a central core 7 of triangular or trapezoidal outline.

Chacun de ces canaux présente une section rectangulaire correspondant à la section de câbles électriques plats 8, relativement larges, du type comportant une âme métallique axiale 8a de part et d'autre de laquelle sont prévus deux conducteurs 9, l'ensemble étant noyé dans la gaine isolante du câble correspondant. En conséquence, la largeur de ces canaux est identique à celle de tels câbles. De plus, les plans médians AB et CD de ces canaux sont disposés perpendiculairement au plan XY de jonction des deux parties complémentaires 3 du corps 1 (voir figures 11 et 14).Each of these channels has a rectangular section corresponding to the section of relatively wide flat electric cables 8 of the type comprising an axial metallic core 8a on either side of which two conductors 9 are provided, the assembly being embedded in the insulating sheath of the corresponding cable. Consequently, the width of these channels is identical to that of such cables. In addition, the median planes AB and CD of these channels are arranged perpendicular to the plane XY of junction of the two complementary parts 3 of the body 1 (see FIGS. 11 and 14).

Sur leurs faces internes, les deux parties 3 du corps 1 comportent également des reliefs complémentaires destinés à assurer un positionnement correct de celles-ci l'une sur l'autre. Ces reliefs peuvent consister en deux tétons 10, prè- vus sur l'une de ces deux parties et deux cavités correspondantes 11 ménagées sur l'autre.On their internal faces, the two parts 3 of the body 1 also include complementary reliefs intended to ensure correct positioning of these one on the other. These reliefs can consist of two pins 10, provided on one of these two parts and two corresponding cavities 11 formed on the other.

Le corps isolant, 1 constitué par la réunion de ces deux parties complèmentaires, présente une forme tronconique ainsi qu'il apparait sur la figure 1. A son sommet, ce corps porte un plot 12 pourvu d'une série de nervures superposées 13 ayant une section en forme de dents de loup. Ces nervures sont destinées à permettre l'accrochage du capuchon 2 dans la position d'enfoncement maximum possible de celui-ci, lorsque l'on procède à la connexion de deux câbles à raccorder, la partie supérieure de la paroi interne de ce capuchon comportant elle-même une série de nervures d'accrochage complémentaires 14.The insulating body, 1 constituted by the union of these two complementary parts, has a frustoconical shape as it appears in FIG. 1. At its top, this body carries a stud 12 provided with a series of superimposed ribs 13 having a wolf tooth section. These ribs are intended to allow the attachment of the cap 2 in the maximum insertion position possible thereof, when one proceeds to the connection of two cables to be connected, the upper part of the inner wall of this cap comprising itself a series of complementary hooking ribs 14.

Les nervures 13, prévues sur les deux parties complémentaires 3, sont séparées par des parties en relief 15 qui sont aptes à constituer des glissières de guidage pour le capuchon 2 lors que son enfoncement. A cet effet, celui-ci comporte des rainures parallèles 16 de même section. Lorsque le connecteur est en attente d'utilisation, le capuchon 2 se trouve dans la position de relévement représentée à la figure 1, seule la première nervure 14 de celui-ci étant accrochée sur la première nervure 13 du corps 1.The ribs 13, provided on the two complementary parts 3, are separated by raised parts 15 which are capable of constituting guide rails for the cap 2 when it is pushed in. To this end, it has parallel grooves 16 of the same section. When the connector is waiting for use, the cap 2 is in the lifting position shown in FIG. 1, only the first rib 14 of the latter being hooked on the first rib 13 of the body 1.

Il convient de noter que la paroi interne de ce capuchon présente une forme tronconique de même que la paroi externe du corps 1.It should be noted that the internal wall of this cap has a frustoconical shape as does the external wall of the body 1.

Les deux canaux 6 ménagés dans ce corps comportent, dans leur fond, une extension 17 dont la largeur est plus faible pour correspondre à celle de câbles électriques plats 18 de faible largeur comportant uniquement deux conducteurs 19 sans âme axiale, contrairement aux câbles 8 déjà mentionnés. Les extensions ainsi prévues sont donc séparées, de la partie principale des canaux 6, par des épaulements 20 qui sont aptes à servir de butées pour des câbles plats 8 de grande largeur lors de leur enfoncement dans ces canaux.The two channels 6 formed in this body have, in their bottom, an extension 17 whose width is narrower to correspond to that of flat electric cables 18 of small width comprising only two conductors 19 without an axial core, unlike cables 8 already mentioned . The extensions thus provided are therefore separated, from the main part of the channels 6, by shoulders 20 which are able to serve as stops for flat cables 8 of large width when they are inserted into these channels.

En regard des bords des deux canaux 6, il est prévu deux lames métalliques de connexion 21. Ces lames sont disposées dans un même plan perpendiculaire à l'axe du corps 1 et elles sont montées coulissantes dans des fentes 22 de ce corps. De même, en regard des extensions 17 des canaux 6, il est prévu deux autres lames similaires de connexion 23 montées coulissantes dans des fentes 24 du corps 1.Opposite the edges of the two channels 6, two metal connection blades 21 are provided. These blades are arranged in the same plane perpendicular to the axis of the body 1 and they are slidably mounted in slots 22 of this body. Likewise, opposite the extensions 17 of the channels 6, two other similar connection blades 23 are slidably mounted in slots 24 of the body 1.

Les deux lames de connexion 21 et 23, qui sont situés sur un même côté du connecteur, sont constitués par les branches latérales d'une pièce métallique 25 en forme générale de U dont la branche médiane présente une inclinaison similaire à celle de la paroi externe du corps 1. En position d'attente, la branche médiane de chacune de ces deux pièces de connexion fait saillie par rapport à cette paroi, comme représenté à la figure 5. Cependant, l'agencement est tel que la branche médiane de chacune de ces piéces se trouve repoussée par la paroi interne du capuchon 2 lors de son enfoncement, la paroi externe du corps 1 comportant deux légères dépressions 26 susceptibles de recevoir la branche médiane de ces deux pièces lorsqu'elles se trouvent com- plétement repoussées par le capuchon 2.The two connection blades 21 and 23, which are located on the same side of the connector, are formed by the lateral branches of a metal part 25 in the general shape of a U, the middle branch of which has an inclination similar to that of the external wall. of the body 1. In standby position, the middle branch of each of these two connection pieces protrudes relative to this wall, as shown in FIG. 5. However, the arrangement is such that the middle branch of each of these parts is pushed back by the internal wall of the cap 2 when it is pushed in, the external wall of the body 1 comprising two slight depressions 26 capable of receiving the middle branch of these two parts when they are completely pushed back by the cap 2.

Conformément à une caractéristique importante du présent connecteur, le corps 1 de celui-ci renferme deux barrettes amovibles 27 disposées à l'intérieur des canaux 6. Du reste, ces barrettes, dont l'une est représentée à plus grande échelle sur la figure 7, présentent une largeur identique à ces canaux, leur section étant similaire à celle des câbles plats 8 relativement larges qui comportent une âme axiale 8a. En conséquence, ces barrettes se trouvent arrêtées par les épaulements 20 prévus dans les canaux 6 (voir figure 5).In accordance with an important characteristic of the present connector, the body 1 thereof contains two removable bars 27 arranged inside the channels 6. Furthermore, these bars, one of which is shown on a larger scale in FIG. 7 , have a width identical to these channels, their section being similar to that of relatively wide flat cables 8 which have an axial core 8a. Consequently, these bars are stopped by the shoulders 20 provided in the channels 6 (see FIG. 5).

Sur l'un et l'autre de ses bords, chacune de ces barrettes comporte une gorge longitudinale 28 destinée à recevoir un conducteur indépendant 29 pouvant faire partie d'un faisceau de tels conducteurs. Ainsi, chaque barrette 27 peut recevoir les deux conducteurs d'une même paire qui doivent être raccordés aux deux conducteurs de la paire correspondante prévue sur le faisceau suivant de conducteurs.On both of its edges, each of these bars has a longitudinal groove 28 intended to receive an independent conductor 29 which may form part of a bundle of such conductors. Thus, each strip 27 can receive the two conductors of the same pair which must be connected to the two conductors of the corresponding pair provided on the next bundle of conductors.

En regard de la lame correspondante 21 de connexion, située du côté de l'entrée du canal 6 respectif, chaque barrette 27 comporte une rainure transversale 30 de plus grande profondeur que la gorge longitudinale 28. Comme il sera expliqué par la suite, cette rainure permet d'éviter tout risque de coupure du conducteur correspondant 29.Opposite the corresponding connection blade 21, located on the entry side of the respective channel 6, each bar 27 has a transverse groove 30 of greater depth than the longitudinal groove 28. As will be explained below, this groove avoids any risk of cutting the corresponding conductor 29.

De plus, chaque barrette 27 porte une patte de préhension 31, qui fait saillie à l'extérieur du corps du connecteur, ainsi que cela apparait clairement sur les figures 1 et 2. Ces pattes sont destinées à permettre une extraction facile des barrettes amovibles 27, lorsque celles-ci ne sont pas utilisées.In addition, each bar 27 carries a gripping tab 31, which projects outside the body of the connector, as can be seen clearly in FIGS. 1 and 2. These tabs are intended to allow easy removal of the removable bars 27 , when these are not used.

Le corps du connecteur est également pourvu d'un étrier métallique de connexion 32 destiné à assurer une liaison électrique entre les âmes axiales 8a de deux câbles larges 8 lorsque le connecteur est utilisé pour le raccordement de tels câbles. Cet étrier en fil métallique est disposé dans le plan de jonction des deux parties complémentaires 3 du corps 1. Il présente une forme générale en U, sa branche médiane 33 étant disposée transversalement à quelque distance du fond des canaux 6, cependant que ses branches latérales 34 se trouvent situées à l'extérieur du corps 1, comme représenté sur la figure 4. Ces deux dernières branches ont une inclinaison similaire à celle de la paroi externe du corps 1 et elles sont destinées à être repoussées vers l'intérieur lors de l'enfoncement du capuchon 2. Les extrémités 35 de ces deux branches sont coudées vers l'intérieur en direction des canaux 6, de sorte qu'elles viennent s'engager dans ces canaux lorsque le capuchon 2 est enfoncé, et ce, grâce à l'élasticité du présent étrier 32.The connector body is also provided with a metal connection bracket 32 intended to provide an electrical connection between the axial cores 8a of two wide cables 8 when the connector is used for the connection of such cables. This metal wire bracket is arranged in the junction plane of the two complementary parts 3 of the body 1. It has a general U-shape, its middle branch 33 being arranged transversely at some distance from the bottom of the channels 6, while its lateral branches 34 are located outside the body 1, as shown in FIG. 4. These last two branches have an inclination similar to that of the external wall of the body 1 and they are intended to be pushed inwards during the insertion of the cap 2. The ends 35 of these two branches are bent inwards towards the channels 6, so that they come to engage in these channels when the cap 2 is pressed, thanks to the elasticity of the present stirrup 32.

A ce sujet, il convient de noter que les barrettes amovibles 27 présentent un trou 36 en regard des extrémités 35 de cet étrier. Ces trous peuvent donc recevoir ces extrémités lors de l'enfoncement du capuchon 2, si les barrettes 27 sont en place. Ceci assure alors l'immobilisation de ces dernières.In this regard, it should be noted that the removable bars 27 have a hole 36 opposite the ends 35 of this stirrup. These holes can therefore receive these ends when the cap 2 is pushed in, if the bars 27 are in place. This then ensures the immobilization of the latter.

Entre les deux lames de connexion 23, qui sont situées dans le fond des canaux 6 ou plus exactement à l'endroit des extensions 17 de ces derniers. il est prévu un écran isolant 37. Cet écran de forme plate, est disposé sensiblement dans le plan de jonction XY des deux parties complémentaires du corps 1. De plus, il est mobile et peut coulisser selon ce plan. A cet effet, cet écran comporte une lumière oblongue 38 à l'intérieur de laquelle est disposée la branche médiane 33 de l'étrier de connexion 32.Between the two connection blades 23, which are located in the bottom of the channels 6 or more exactly at the location of the extensions 17 of the latter. an insulating screen 37 is provided. This flat screen is disposed substantially in the XY junction plane of the two complementary parts of the body 1. In addition, it is movable and can slide along this plane. To this end, this screen includes an oblong opening 38 inside which is arranged the middle branch 33 of the connection bracket 32.

Lorsque le connecteur est en attente d'utilisation, l'écran 37 se trouve dans la position représentée à la figure 5. Il est alors partiellement engagé dans les extensions 17 des deux canaux 6, de sorte qu'une partie de cet écran se trouve située entre les deux lames de connexion 23 pour interdire tout danger d'arc entre ces deux lames.When the connector is waiting for use, the screen 37 is in the position shown in FIG. 5. It is then partially engaged in the extensions 17 of the two channels 6, so that part of this screen is located between the two connection blades 23 to prevent any danger of arcing between these two blades.

De préférence, les arêtes des lames de connexion 21 et 23 sont susceptibles de se déformer pour épouser le profil des conducteurs métalliques à connecter afin d'obtenir un contact optimal. De plus, ces lames peuvent être pourvues d'un revêtement métallique particulier permettant d'obtenir leur soudure sur les conducteurs correspondants lors du premier échauffement qui se produit.Preferably, the edges of the connection blades 21 and 23 are capable of deforming to conform to the profile of the metal conductors to be connected in order to obtain optimal contact. In addition, these blades can be provided with a particular metallic coating making it possible to obtain their soldering on the corresponding conductors during the first heating which occurs.

D'autre part, il existe, dans le noyau central 7 du corps 1, des rainures 39 susceptibles d'assurer un dégazage en cas d'effet de foudre, afin d'éviter tout risque d'éclatement du connecteur.On the other hand, there are, in the central core 7 of the body 1, grooves 39 capable of ensuring degassing in the event of lightning effect, in order to avoid any risk of bursting of the connector.

Par ailleurs, il est prévu, à la base des deux parties complémentaires 3 du corps 1, des collerettes 40 auxquelles correspondent des alvéoles 41 ménagées à la base du capuchon 20. Ces collerettes ont pour but de retenir en place la graisse d'étanchéité rapportée autour du corps 10. Par ailleurs, du fait de leur emboîtement, ces collerettes évitent l'établissement de lignesde fuite à partir des lames de connexion 22 les plus proches de l'entrée des canaux 6.Furthermore, there are provided, at the base of the two complementary parts 3 of the body 1, flanges 40 to which correspond cells 41 formed at the base of the cap 20. These flanges are intended to retain in place the added sealing grease around the body 10. Furthermore, because of their interlocking, these collars avoid the establishment of vanishing lines from the connection blades 22 closest to the entry of the channels 6.

Les différents modes d'utilisation du présent connecteur sont les suivants:The different modes of use of this connector are as follows:

1) Connexion de deux paires de conducteurs indépendants (voir figures 10 et 11):1) Connection of two pairs of independent conductors (see Figures 10 and 11):

Dans ce cas, les deux barrettes amovibles 27 sont utilisées pour servir de supports aux extrémités des conducteurs correspondants, celles-ci étant engagées dans les gorges longitudinales 28 prévues sur les bords de ces barrettes.In this case, the two removable bars 27 are used to serve as supports at the ends of the corresponding conductors, these being engaged in the longitudinal grooves 28 provided on the edges of these bars.

Il suffit ensuite d'enfoncer complètement la capuchon 2 pour obtenir la connexion désirée. En effet, lors de son enfoncement, ce capuchon vient repousser les deux pièces de connexion 25 comme représenté sur la figure 10. Ceci amène donc les lames inférieures 21 à pénétrer dans les canaux 6 et par suite, à s'enfoncer dans la gaine isolante des conducteurs 29, de sorte que leur arête vient directement au contact des fils conducteurs correspondants.Then just fully push the cap 2 to get the desired connection. In fact, when it is pushed in, this cap pushes the two connection pieces 25 as shown in FIG. 10. This therefore causes the lower blades 21 to penetrate into the channels 6 and consequently to sink into the insulating sheath of the conductors 29, so that their edge comes directly into contact with the corresponding conductive wires.

Ainsi, l'arête de chaque lame de connexion 21 se trouve en contact avec le fil de l'un des conducteurs 29 portés par une barrette 27 et avec le fil de l'un des conducteurs portés par l'autre barrette 27 sur le même côté du connecteur. Il en est de même pour l'autre lame de connexion 21, ce qui assure donc bien les connexions voulues.Thus, the edge of each connection blade 21 is in contact with the wire of one of the conductors 29 carried by a strip 27 and with the wire of one of the conductors carried by the other strip 27 on the same side of the connector. It is the same for the other connection blade 21, which therefore ensures the desired connections.

Compte tenu qu'à cet endroit les barrettes 27 comportent leur rainure transversale 30 de plus grande profondeur que les gorges longitudinales 28, chaque conducteur peut se déformer, comme représenté à la figure 10, ce qui évite tout risque de coupure par les lames de connexion 21.Given that at this point the bars 27 have their transverse groove 30 of greater depth than the longitudinal grooves 28, each conductor can deform, as shown in FIG. 10, which avoids any risk of cutting by the connection blades 21.

De plus, la légére déformation prévue sur les arêtes de ces lames permet qu'il se produise alors une sorte de "raclage" ou de pelage de la gaine isolante, et non pas une simple pénétration dans la matière de cette gaine selon une direction perpendiculaire à l'axe du conducteur, ce qui risquerait d'entraîner une détérioration de celui- ci.In addition, the slight deformation provided on the edges of these blades allows a kind of "scraping" or peeling of the insulating sheath to occur, and not a simple penetration into the material of this sheath in a perpendicular direction. to the axis of the driver, which could lead to deterioration of the driver.

Comme déjà indiqué, l'enfoncement du capuchon 2 a également pour effet de faire pénétrer les extrémités 35 de l'étrier de connexion 32 dans les trous des barrettes 27, ce qui assure leur immobilisation en place. Cependant, il faut également noter que dans le présent mode d'utilisation l'écran isolant 37 est resté dans sa position initiale. En conséquence, une partie de cet écran se trouve interposé entre les deux lames de connexion 23, ce qui évite alors tout risque d'amorçage d'un arc entre celles-ci.As already indicated, the depression of the cap 2 also has the effect of making the ends 35 of the connection bracket 32 penetrate into the holes of the bars 27, which ensures their immobilization in place. However, it should also be noted that in the present mode of use the insulating screen 37 has remained in its initial position. Consequently, part of this screen is interposed between the two connection blades 23, which then avoids any risk of striking an arc between them.

2) Connexion de deux câbles larges comportant chacun une âme axiale: (voir figures 12 et 14):2) Connection of two wide cables each comprising an axial core: (see figures 12 and 14):

Dans un tel cas, il convient d'enlever complètement les deux barrettes amovibles 27 en les extrayant du corps 1 par traction sur leur patte 31. Les extrémités des deux câbles 4 à connecter peuvent alors être engagées dans les canaux 6 jusqu'à ce qu'elles viennent en butée contre les épaulements 20.In such a case, the two removable bars 27 should be completely removed by extracting them from the body 1 by pulling on their tab 31. The ends of the two cables 4 to be connected can then be engaged in the channels 6 until 'They abut against the shoulders 20.

Comme précédemment, il suffit ensuite d'enfoncer complètement le capuchon 2 pour obtenir les connexions désirées. En effet, ce capuchon vient alors repousser les deux pièces de connexion 25, de sorte que les deux lames 21 sont amenées à pénétrer dans la gaine isolante des câbles 8, ce qui permet à leur arête de venir en contact direct avec les conducteurs 9 prévus sur les bords correspondants de ces câbles. On obtient ainsi une liaison électrique entre les conducteurs des deux câbles 9 qui sont situés sur un même côté. Comme dans le cas précédent, la gaine isolante se trouve alors "raclée" par l'arête des lames de connexion, ce qui évite tout risque de coupure des conducteurs 9.As before, it then suffices to fully press the cap 2 to obtain the desired connections. Indeed, this cap then pushes back the two connection pieces 25, so that the two blades 21 are caused to penetrate the insulating sheath of the cables 8, which allows their edges to come into direct contact with the conductors 9 provided on the corresponding edges of these cables. An electrical connection is thus obtained between the conductors of the two cables 9 which are located on the same side. As in the previous case, the insulating sheath is then "scraped" by the edge of the connection blades, which avoids any risk of cutting the conductors 9.

Cependant, l'enfoncement du capuchon 2 assure également la pénétration des extrémités coudées 35 de l'étrier de connexion 33 à l'intérieur des canaux 6. Les pointes de ces extrémités sont ainsi amenées à pénétrer dans la gaine isolante des deux câbles 8, de sorte qu'elles viennent en contact direct avec l'âme axiale 8a de chacun de ces câbles. Ceci assure une liaison électrique entre les âmes de ces deux câbles et améliore la tenue mécanique de l'ensemble.However, the depression of the cap 2 also ensures the penetration of the bent ends 35 of the connection bracket 33 inside the channels 6. The tips of these ends are thus caused to penetrate into the insulating sheath of the two cables 8, so that they come into direct contact with the axial core 8a of each of these cables. This ensures an electrical connection between the cores of these two cables and improves the mechanical strength of the assembly.

De même que dans le cas précédent, l'écran isolant 37 est resté dans sa position initiale. Dans ces conditions, il assure l'isolement voulu entre les deux lames de connexion 23 en évitant tout risque d'amorçage d'arc entre celles-ci.As in the previous case, the insulating screen 37 remained in its initial position. Under these conditions, it provides the desired isolation between the two connection blades 23 while avoiding any risk of arcing between them.

3) Connexion de deux câbles dépourvus d'une âme axiale (voir figures 13 et 15):3) Connection of two cables without an axial core (see Figures 13 and 15):

Dans un tel cas, il convient également de retirer les barrettes amovibles 27 pour pouvoir engager, à l'intérieur des canaux 6, les extrémités des deux câbles 18 à connecter. Cependant, contrairement au cas précédent, les extrémités de ces câbles ne sont alors pas arrêtées par les épaulements 20 prévus dans ces canaux. En effet, comme leur largeur est plus faible que celle des câbles 8, les extrémités des câbles 18 s'engagent jusqu'au fond des extensions 17 des canaux 6, comme représenté sur la figure 13. Lors de ce mouvement, les extrémités de ces câbles repoussent l'écran mobile 37 jusque dans la position illustrée sur cette même figure.In such a case, it is also advisable to remove the removable bars 27 in order to be able to engage, inside the channels 6, the ends of the two cables 18 to be connected. However, unlike the previous case, the ends of these cables are not then stopped by the shoulders 20 provided in these channels. Indeed, as their width is narrower than that of the cables 8, the ends of the cables 18 engage to the bottom of the extensions 17 of the channels 6, as shown in FIG. 13. During this movement, the ends of these cables push the movable screen 37 back into the position illustrated in this same figure.

Il suffit ensuite d'enfoncer complètement le capuchon 2 sur le corps 1 pour obtenir les connexions désirées. En effet, lors de son enfoncement, ce capuchon repousse les deux pièces de connexion 25 de sorte que les lames 23, situées dans le fond des canaux 6, ou plus exactement à l'endroit des extensions 17 de ces canaux, sont amenées à pénétrer dans la gaine isolante des cables 18 situés en regard.Then simply push the cap 2 fully onto the body 1 to obtain the desired connections. In fact, when it is pushed in, this cap pushes back the two connection pieces 25 so that the blades 23, situated in the bottom of the channels 6, or more exactly at the location of the extensions 17 of these channels, are caused to penetrate in the insulating sheath of the cables 18 located opposite.

Ainsi les arêtes de ces deux lames 23 viennent en contact direct avec les fils conducteurs 19 prévus à l'intérieur des câbles 18 (voir figure 15). On obtient donc de la sorte des connexions similaires à celles réalisées dans le cas précédent.Thus the edges of these two blades 23 come into direct contact with the conductive wires 19 provided inside the cables 18 (see FIG. 15). We thus obtain in this way connections similar to those made in the previous case.

A ce sujet, il convient de noter que les connexions réalisées sont parfaites car les extrémités des câbles 18 se trouvent complètement immobilisées à l'intérieur des extensions 17 des canaux 6. Or, cela n'aurait pas été le cas si on avait utilisé un connecteur comportant uniquement des canaux ayant la largeur de câbles plus large pourvus d'une âme axiale, tels que les câbles 8 mentionnés précédemment. Il faut également noter que dans les divers modes d'utilisation du présent connecteur, on obtient d'excellentes conditions d'application des arêtes des lames de connexion sur les conducteurs correspondants. Ceci est dû à l'agencement général du présent connecteur et à l'inclinaison de la paroi externe du corps de celui-ci et de la branche médiane des pièces de connexion 25. Cependant ceci est également dû au fait qu'il se produit en quelque sorte une adaptation des différentes pièces du fait que le corps du présent connecteur est constitué par deux parties complémentaires 3 qui peuvent légèrement bouger l'une par rapport à l'autre et s'adapter en conséquence.In this regard, it should be noted that the connections made are perfect because the ends of the cables 18 are completely immobilized inside the extensions 17 of the channels 6. However, this would not have been the case if we had used a connector comprising only channels having the width of wider cables provided with an axial core, such as the cables 8 mentioned above. It should also be noted that in the various modes of use of this connector, excellent conditions of application of the edges of the connection blades are obtained on the corresponding conductors. This is due to the general arrangement of the present connector and to the inclination of the external wall of the body thereof and of the middle branch of the connection pieces 25. However, this is also due to the fact that it occurs in somehow an adaptation of the different parts of the fact that the body of the present connector is constituted by two complementary parts 3 which may slightly move a lot relative to each other and adapt accordingly.

La conception du présent connecteur permet également de connecter un câble d'un type déterminé avec un câble d'un autre type, ou bien encore avec des conducteurs indépendants placés sur l'une des barrettes amovibles 27. En effet, ces diverses combinaisons sont parfaitement possibles.The design of this connector also makes it possible to connect a cable of a specific type with a cable of another type, or even with independent conductors placed on one of the removable bars 27. In fact, these various combinations are perfectly possible.

Comme il a déjà été indiqué, la fabrication du corps du présent connecteur sous forme des deux parties complémentaires 3, destinées à être réunies l'une contre l'autre, a l'avantage de permettre le moulage de ce corps dans un moule de conception très simple. Cependant, ceci facilite également l'assemblage ultérieur des diverses pièces prévues. En effet, l'écran isolant 37 ainsi que l'étrier transversal 32 de connexion peuvent être mis en place entre ces deux parties complémentaires avant leur rabattement l'une contre l'autre. Lors de la réunion de ces deux parties, les tétons 10 et les cavités 11 assurent un positionnement convenable de ces deux parties l'une par rapport à l'autre.As already indicated, the manufacture of the body of the present connector in the form of two complementary parts 3, intended to be joined together, has the advantage of allowing the molding of this body in a design mold very simple. However, this also facilitates the subsequent assembly of the various parts provided. Indeed, the insulating screen 37 as well as the transverse stirrup 32 for connection can be put in place between these two complementary parts before their folding against one another. During the meeting of these two parts, the pins 10 and the cavities 11 ensure proper positioning of these two parts relative to each other.

Cependant, la réalisation du corps 1 sous forme de deux parties complémentaires a également l'avantage de permettre un coincement efficace des câbles à connecter par serrage des deux parties complémentaires 3 sur ceux-ci sous l'effet des pressions exercées par ce capuchon 3 lors de son enfoncement.However, the production of the body 1 in the form of two complementary parts also has the advantage of allowing effective clamping of the cables to be connected by tightening the two complementary parts 3 thereon under the effect of the pressures exerted by this cap 3 during of its depression.

Mais le principal avantage du présent connecteur réside évidement dans le caractère polyvalent de celui-ci, du fait qu'il peut assurer indifféremment la connexion de deux types distincts de câbles plats, de largeur différente, et celle de conducteurs distincts faisant partie de deux faisceaux de conducteurs, devant être accordés l'un à la suite de l'autre. Or, compte tenu de l'agencement prévu, les contacts réalisés sont assurés, dans chaque cas, de façon absolument parfaite, puisque les câbles ou conducteurs distincts à raccorder, sont placés dans des logements qui correspondent exactement à leur dimension et que par ailleurs, les pressions appliquées sur les lames de connexion s'exercent dans des conditions optimales.However, the main advantage of this connector obviously lies in its versatile nature, since it can interconnect two distinct types of flat cables, of different width, and that of separate conductors forming part of two bundles. conductors, to be tuned one after the other. However, taking into account the planned arrangement, the contacts made are ensured, in each case, in an absolutely perfect manner, since the separate cables or conductors to be connected, are placed in housings which correspond exactly to their dimension and that, moreover, the pressures applied to the connection blades are exerted under optimal conditions.
