Description

La présente invention concerne d'une manière générale le raccordement d'un câble électrique à un élément conducteur.The present invention relates generally to the connection of an electric cable to a conductive element.

Elle vise plus particulièrement le cas où, présentant localement au moins un perçage taraudé, cet élément conducteur forme par lui-même une borne de connexion à vis.It relates more particularly to the case where, locally having at least one tapped hole, this conductive element by itself forms a screw connection terminal.

Cela est le cas, par exemple, de certaines au moins des barres équipant les armoires électriques, et cela est le cas, également, des barreaux que comportent au moins certains répartiteurs.This is the case, for example, of at least some of the bars equipping the electrical cabinets, and this is also the case, of the bars that comprise at least some distributors.

Il est connu, dans de tels cas, de rapporter, en pratique par sertissage, sur l'extrémité préalablement dénudée d'un câble électrique à raccorder, une cosse comportant une oreille par laquelle l'ensemble peut venir en prise avec la vis d'une des bornes de connexion de l'élément conducteur concerné.It is known, in such cases, to attach, in practice by crimping, to the previously stripped end of an electric cable to be connected, a terminal comprising an ear by which the assembly can come into engagement with the screw. one of the connection terminals of the conductive element concerned.

Mais, pour des raisons pratiques, il est de plus en plus fréquemment substitué à une telle cosse un embout de câblage, qui présente avantageusement une collerette en matière isolante par laquelle il est engagé sur la gaine isolante du câble électrique sur lequel il est rapporté, mais dont la partie active métallique, formant cosse, est dépourvue de toute oreille.However, for practical reasons, it is more and more frequently substituted for such a terminal with a wiring end-piece, which advantageously has a flange made of insulating material by which it is engaged on the insulating sheath of the electric cable on which it is attached, but whose metallic active part, forming a pod, is devoid of any ear.

Il a été proposé de mettre en oeuvre, dans un tel cas, un connecteur adapté à former un adaptateur entre le câble électrique équipé de son embout de câblage et l'élément conducteur auquel il doit être raccordé.It has been proposed to implement, in such a case, a connector suitable for forming an adapter between the electric cable equipped with its wiring end-piece and the conductive element to which it must be connected.

Ce connecteur, qui est en pratique en métal, et qui peut tout aussi bien être mis en oeuvre pour un câble électrique nu, c'est-à-dire pour un câble électrique dépourvu d'embout de câblage, comporte, d'une part, un bloc de câblage, qui, pour l'engagement du câble électrique, présente au moins un perçage appartenant à une borne de connexion, et, d'autre part, une embase de fixation, qui, elle, est adaptée à permettre l'assujettissement de l'ensemble à l'élément conducteur auquel le câble électrique doit être raccordé.This connector, which is in practice made of metal, and which can just as easily be used for a bare electric cable, that is to say for an electric cable without a cable end, comprises, on the one hand , a wiring block, which, for the engagement of the electric cable, has at least one hole belonging to a connection terminal, and, on the other hand, a fixing base, which is adapted to allow the securing the assembly to the conductive element to which the electric cable must be connected.

La présente invention a d'une manière générale pour objet des dispositions permettant de faciliter la mise en oeuvre d'un tel connecteur.The present invention generally relates to provisions to facilitate the implementation of such a connector.

De manière plus précise, elle a pour objet un connecteur du genre concerné, qui, suivant une première de ces dispositions, est caractérisé en ce que la face d'entrée de son bloc de câblage, c'est-à-dire la face de ce bloc de câblage sur laquelle débouche le perçage que comporte celui-ci pour l'engagement du câble électrique, s'étend globalement en oblique par rapport à l'axe de ce perçage.More specifically, it relates to a connector of the type concerned, which, according to a first of these provisions, is characterized in that the input face of its wiring block, that is to say the face of this wiring block on which the hole that the latter opens for the engagement of the electric cable, extends generally obliquely relative to the axis of this hole.

Grâce à cette disposition, l'entrée du perçage se trouve encore visible lorsque le connecteur est observé en vue de dessus, ce qui, en permettant d'opérer à vue, facilite avantageusement l'engagement du câble électrique dans ce perçage.Thanks to this arrangement, the entry of the hole is still visible when the connector is viewed from above, which, by allowing to operate by sight, advantageously facilitates the engagement of the electric cable in this hole.

Cet avantage est particulièrement appréciable lorsque l'élément conducteur sur lequel se fait ainsi le raccordement du câble électrique est une barre d'armoire électrique ou un barreau de répartiteur, parce que ce raccordement intervient alors dans un environnement généralement encombré, sans grande visibilité.This advantage is particularly appreciable when the conductive element on which the electrical cable is thus connected is an electrical cabinet bar or a distributor bar, because this connection then occurs in a generally congested environment, without great visibility.

Suivant une deuxième disposition, le connecteur de l'invention est encore caractérisé en ce que son embase de fixation se réduit à une platine vis-à-vis de laquelle fait saillie son bloc de câblage.According to a second arrangement, the connector of the invention is further characterized in that its fixing base is reduced to a plate opposite which its wiring block projects.

Outre la simplicité de réalisation à laquelle elle conduit, cette disposition se prête avantageusement à un développement suivant lequel le perçage que comporte le bloc de câblage traverse de part en part ce bloc de câblage.In addition to the simplicity of construction to which it leads, this arrangement advantageously lends itself to a development according to which the bore which the wiring block comprises passes right through this wiring block.

Ainsi, une fois l'embout de câblage du câble électrique engagé dans ce perçage, il est avantageusement possible de contrôler, à vue, en vue de dessus, que la mise en place du câble électrique est correcte, ce qui est effectivement le cas lorsqu'il est possible de constater que l'embout de câblage ressort de l'autre côté du bloc de câblage.Thus, once the wiring end of the electric cable engaged in this drilling, it is advantageously possible to check, on sight, in top view, that the installation of the electric cable is correct, which is actually the case when '' it can be seen that the cable end protrudes from the other side of the cable block.

Pour favoriser cette émergence tout en conservant avantageusement une certaine compacité pour l'ensemble, le perçage du bloc de câblage se prolonge, suivant un autre développement de l'invention, au-delà de ce bloc de câblage, en mordant au moins pour partie sur l'épaisseur de la platine formant l'embase de fixation.To promote this emergence while advantageously retaining a certain compactness for the assembly, the drilling of the wiring block is extended, according to another development of the invention, beyond this wiring block, biting at least partially on the thickness of the plate forming the fixing base.

Les conditions étant égales par ailleurs, l'épaisseur hors tout du connecteur suivant l'invention peut avantageusement s'en trouver réduite d'autant.The conditions being equal, moreover, the overall thickness of the connector according to the invention can advantageously be reduced accordingly.

Enfin, suivant un autre développement éventuel de l'invention, la platine formant l'embase de fixation du connecteur suivant l'invention comporte, pour son assujettissement à l'élément conducteur auquel le câble électrique doit être raccordé, au moins une échancrure qui ouvre du côté opposé à la face d'entrée du bloc de câblage.Finally, according to another possible development of the invention, the plate forming the fixing base of the connector according to the invention comprises, for its securing to the conductive element to which the electric cable must be connected, at least one notch which opens on the side opposite the input side of the wiring block.

Il en résulte que l'installation du connecteur suivant l'invention sur l'élément conducteur auquel le câble électrique doit être raccordé peut avantageusement se faire sans un dévissage complet de la vis de la borne de connexion correspondante.It follows that the installation of the connector according to the invention on the conductive element to which the electric cable must be connected can advantageously be done without completely unscrewing the screw of the corresponding connection terminal.

Les caractéristiques et avantages de l'invention ressortiront d'ailleurs de la description qui va suivre, à titre d'exemple, en référence aux dessins schématiques annexés sur lesquels :

  • la figure 1 est une vue en perspective d'un connecteur suivant l'invention, vu de l'avant ;
  • la figure 2 en est une autre vue en perspective, vu de l'arrière ;
  • la figure 3 en est une vue de dessus, suivant la flèche III de la figure 1.
The characteristics and advantages of the invention will become apparent from the description which follows, by way of example, with reference to the appended schematic drawings in which:
  • Figure 1 is a perspective view of a connector according to the invention, seen from the front;
  • Figure 2 is another perspective view, seen from the rear;
  • FIG. 3 is a top view thereof, along arrow III of FIG. 1.

Tel qu'illustré à la figure 1, il s'agit, globalement, de raccorder, à un élément conducteur 10 schématisé en traits interrompus sur la figure 1, un câble électrique 11.As illustrated in FIG. 1, it is a question, overall, of connecting, to a conductive element 10 shown diagrammatically in broken lines in FIG. 1, an electric cable 11.

A titre d'exemple, il est supposé, sur cette figure 1, ainsi que sur les figures 2 et 3, que, pour ce raccordement, le câble électrique 11 est équipé, à son extrémité, d'un embout de câblage 12.By way of example, it is assumed, in this FIG. 1, as well as in FIGS. 2 and 3, that, for this connection, the electric cable 11 is equipped, at its end, with a wiring end 12.

De manière connue en soi, cet embout de câblage 12 comporte, d'une part, une partie active métallique 13, qui est sertie sur l'extrémité préalablement dénudée de l'âme conductrice 14 du câble électrique 11, et, d'autre part, une collerette en matière isolante 15, qui est engagée sur la gaine en matière isolante 16 de celui-ci.In a manner known per se, this wiring end piece 12 comprises, on the one hand, a metallic active part 13, which is crimped on the previously stripped end of the conductive core 14 of the electric cable 11, and, on the other hand , a collar of insulating material 15, which is engaged on the sheath in insulating material 16 thereof.

De manière également connue en soi, l'élément conducteur 10 est par exemple un barreau de répartiteur formant par lui-même des bornes de connexion 17, ce barreau de répartiteur, dont la section transversale est rectangulaire, présentant, de place en place, perpendiculairement à ses faces principales, des perçages taraudés 18 avec lesquels coopèrent des vis de serrage 19.In a manner also known per se, the conductive element 10 is for example a distributor bar forming by itself connection terminals 17, this distributor bar, whose cross section is rectangular, having, from place to place, perpendicularly on its main faces, threaded holes 18 with which the clamping screws 19 cooperate.

Pour raccorder le câble électrique 11 à cet élément conducteur 10, il est mis en oeuvre un connecteur 20.To connect the electric cable 11 to this conductive element 10, a connector 20 is used.

De manière connue en soi, ce connecteur 20 comporte, globalement, d'une part, un bloc de câblage 21, qui, pour l'engagement du câble électrique 11, présente au moins un perçage 22 appartenant à une borne de connexion 23, et, d'autre part, une embase de fixation 25, qui, suivant des dispositions décrites plus en détail ultérieurement, est adaptée à permettre l'assujettissement de l'ensemble à l'élément conducteur 10 auquel le câble électrique 11 doit être raccordé.In a manner known per se, this connector 20 generally comprises, on the one hand, a wiring block 21, which, for the engagement of the electric cable 11, has at least one hole 22 belonging to a connection terminal 23, and , on the other hand, a fixing base 25, which, according to arrangements described in more detail later, is adapted to allow the assembly of the assembly to the conductive element 10 to which the electric cable 11 must be connected.

En pratique, le perçage 22 est globalement cylindrique, et sa section transversale est circulaire.In practice, the bore 22 is generally cylindrical, and its cross section is circular.

Suivant l'invention, la face d'entrée 26 du bloc de câblage 21, c'est-à-dire la face de ce bloc de câblage 21 sur laquelle débouche le perçage 22 qu'il comporte, s'étend globalement en oblique par rapport à l'axe de ce perçage 22.According to the invention, the input face 26 of the wiring block 21, that is to say the face of this wiring block 21 on which opens the bore 22 which it comprises, extends generally obliquely by relative to the axis of this bore 22.

Plus précisément, l'embase de fixation 25 présentant une face d'appui 28, sensiblement plane, par laquelle elle est adaptée à être appliquée à l'élément conducteur 10, suivant l'une des faces principales de celui-ci, la face d'entrée 26 du bloc de câblage 21 fait globalement un dièdre aigu, d'angle A, avec cette face d'appui 28.More specifically, the fixing base 25 having a substantially planar support face 28, by which it is adapted to be applied to the conductive element 10, along one of the main faces thereof, the face d input 26 of the wiring block 21 is generally an acute dihedral, of angle A, with this bearing face 28.

Par exemple, cet angle A est compris entre 30° et 60°, en étant préférentiellement voisin de 45°.For example, this angle A is between 30 ° and 60 °, preferably being close to 45 °.

Dans la forme de réalisation représentée, l'embase de fixation 25 se réduit à une platine vis-à-vis de laquelle le bloc de câblage 21 fait saillie, et, en pratique, cette platine s'étend tout entière du côté du bloc de câblage 21 opposé à sa face d'entrée 26.In the embodiment shown, the mounting base 25 is reduced to a plate vis-à-vis which the wiring block 21 projects, and, in practice, this plate extends entirely on the side of the block of wiring 21 opposite its entry face 26.

Corollairement, du côté de la face d'appui 28 de l'embase de fixation 25, la platine formant cette embase de fixation 25 est à niveau avec le bloc de câblage 21.As a corollary, on the side of the bearing face 28 of the fixing base 25, the plate forming this fixing base 25 is level with the wiring block 21.

Autrement dit, ce bloc de câblage 21 ne fait saillie que sur l'une des faces de la platine formant l'embase de fixation 25, celle opposée à sa face d'appui 28.In other words, this wiring block 21 projects only on one of the faces of the plate forming the fixing base 25, that opposite to its bearing face 28.

Dans la forme de réalisation représentée, le perçage 22 que comporte le bloc de câblage 21 traverse de part en part ce bloc de câblage 21, et, se prolongeant au-delà de celui-ci, il mord au moins pour partie sur l'épaisseur de la platine formant l'embase de fixation 25, en formant, à la surface de cette platine, une goulotte 29 à extrémité 30 borgne.In the embodiment shown, the hole 22 that comprises the wiring block 21 passes right through this wiring block 21, and, extending beyond it, it bites at least partially over the thickness of the plate forming the fixing base 25, forming, on the surface of this plate, a chute 29 with a blind end 30.

Dans la forme de réalisation représentée, le bloc de câblage 21 comporte, parallèlement l'un à l'autre, plusieurs perçages 22, et la platine formant l'embase de fixation 25 s'étend globalement parallèlement au plan contenant les axes de ces perçages 22.In the embodiment shown, the wiring block 21 comprises, parallel to one another, several holes 22, and the plate forming the fixing base 25 extends generally parallel to the plane containing the axes of these holes 22.

Par exemple, et tel que représenté, trois perçages 22 sont prévus côte à côte.For example, and as shown, three holes 22 are provided side by side.

Deux d'entre eux ont des sections transversales identiques, tandis que le troisième a une section transversale inférieure à celle des précédents.Two of them have identical cross sections, while the third has a smaller cross section than the previous ones.

Pour compléter les bornes de connexion 23 auxquelles ils appartiennent, les perçages 22 sont chacun recoupés transversalement par un trou taraudé 32, qui débouche sur la face du bloc du câblage 21 opposée à la platine formant l'embase de fixation 25, et avec lequel est en prise une vis de serrage 33.To complete the connection terminals 23 to which they belong, the holes 22 are each cut transversely by a tapped hole 32, which opens on the face of the wiring block 21 opposite the plate forming the fixing base 25, and with which is in engagement a clamping screw 33.

Préférentiellement, et tel que représenté, la tête 34 de cette vis de serrage 33 est une tête mixte, c'est-à-dire une tête qui comprend à la fois une saignée diamétrale 35 qui débouche à sa périphérie à l'une et l'autre de ses extrémités, et, à la fois, en croix avec la précédente, une saignée 36 dont l'une et l'autre des extrémités sont par contre borgnes.Preferably, and as shown, the head 34 of this clamping screw 33 is a mixed head, that is to say a head which comprises both a diametrical groove 35 which opens at its periphery at one and the 'other of its ends, and, both, cross with the previous one, a groove 36, one and the other of the ends are against blind.

Pour l'assujettissement de l'ensemble à l'élément conducteur 10 auquel le câble électrique 11 doit être raccordé, la platine formant l'embase de fixation 25 comporte, dans la forme de réalisation représentée, au moins une échancrure 38, qui ouvre du côté opposé à la face d'entrée 26 du bloc de câblage 21.To secure the assembly to the conductive element 10 to which the electric cable 11 must be connected, the plate forming the fixing base 25 comprises, in the embodiment shown, at least one notch 38, which opens on the side opposite to the input face 26 of the wiring block 21.

Préférentiellement, cette platine comporte ainsi, parallèlement l'une à l'autre, au moins deux échancrures 38.Preferably, this plate thus comprises, parallel to one another, at least two notches 38.

Dans la forme de réalisation représentée, seules deux échancrures 38 sont prévues.In the embodiment shown, only two notches 38 are provided.

Quoi qu'il en soit, du fait de ces échancrures 38, la mise en place du connecteur 20 suivant l'invention sur l'élément conducteur 10 peut avantageusement se faire sans dépose complète des vis de serrage 19 correspondantes de celui-ci.Anyway, because of these notches 38, the establishment of the connector 20 according to the invention on the conductive element 10 can advantageously be done without complete removal of the corresponding clamping screws 19 thereof.

Il est procédé ensuite à l'engagement, par son embout de câblage 12, du câble électrique 11 dans l'un des perçages 22 du bloc de câblage 21 de ce connecteur 20, tel que schématisé par une flèche F sur la figure 1.The electrical cable 11 is then engaged by its wiring end 12 in one of the holes 22 in the wiring block 21 of this connector 20, as shown diagrammatically by an arrow F in FIG. 1.

L'obliquité de la face d'entrée 26 de ce bloc de câblage 21 facilite avantageusement cet engagement, parce que, lorsque le connecteur 20 est vu par dessus, il permet d'opérer à vue, figure 3.The obliquity of the entry face 26 of this wiring block 21 advantageously facilitates this engagement, because, when the connector 20 is seen from above, it makes it possible to operate by sight, FIG. 3.

Il est possible, conjointement, de contrôler, également à vue, que la mise en place du câble électrique 11 s'est effectuée correctement, lorsque la partie active métallique 13 de son embout de câblage 12 ressort de l'autre côté du bloc de câblage 21.It is possible, jointly, to check, also on sight, that the installation of the electric cable 11 has been carried out correctly, when the metallic active part 13 of its cable end 12 comes out from the other side of the wiring block 21.

Il suffit, ensuite, de serrer la vis de serrage 33 correspondante.It then suffices to tighten the corresponding clamping screw 33.

Bien entendu, la présente invention ne se limite pas à la forme de réalisation décrite et représentée, mais englobe toute variante d'exécution.Of course, the present invention is not limited to the embodiment described and shown, but encompasses any variant.

En particulier, les échancrures que la platine formant l'embase de fixation du connecteur suivant l'invention comporte pour l'assujettissement de l'ensemble à l'élément conducteur auquel doivent être raccordés un ou plusieurs câbles électriques peuvent être remplacées par des perçages.In particular, the notches that the plate forming the connector mounting base according to the invention comprises for securing the assembly to the conductive element to which must be connected one or more electric cables can be replaced by holes.

En outre, pour la mise en oeuvre de ce connecteur, il n'est pas nécessaire que les câbles électriques soient équipés d'un embout de câblage.In addition, for the implementation of this connector, it is not necessary that the electric cables are equipped a cable end.

Le connecteur suivant l'invention convient en effet tout aussi bien au cas où ces câbles électriques sont nus, c'est-à-dire dépourvus de tout embout de câblage, leur engagement dans un de ses perçages se faisant alors simplement par leur extrémité dénudée suivant le même processus que celui décrit.The connector according to the invention is indeed just as well in the case where these electric cables are bare, that is to say devoid of any cable end, their engagement in one of its bores then being done simply by their stripped end. following the same process as described.
