L'agencement de connexion proposé comporte une pièce conductrice de connexion à fente rectiligne de dénudage et de maintien pour les âmes des fils, cette pièce conductrice est immobilisée dans un logement d'un boîtier isolant, ce dernier est doté d'une ouverture, qui comprend une lumière rectiligne de retenue de gaine, au droit de la fente de dénudage et de retenue d'âme et qui est surmontée par un orifice d'introduction de fil pour permettre l'insertion des fils au dessus de l'embouchure dénudante que comporte la fente et l'immobilisation des gaines isolantes des fils dont l'âme est retenue dans ladite fente.The proposed connection arrangement comprises a conductive connection piece with a straight stripping and holding slot for the cores of the wires, this conductive piece is immobilized in a housing of an insulating housing, the latter having an opening, which includes a rectilinear sheath retaining lumen, in line with the stripping and core retaining slot and which is surmounted by a wire introduction orifice to allow the insertion of the wires above the stripping mouth which comprises the slit and the immobilization of the insulating sheaths of the wires whose core is retained in said slit.

Selon une caractéristique de l'invention, la fente est longitudinalement ménagée au long d'une partie profilée de la pièce conductrice qui a, à ce niveau, une section transversale polygonale creuse permettant le guidage en translation, le long de la fente, d'un embout d'outil extérieur qui est conçu pour coulisser à la fois de part et d'autre et entre les bords de la fente, de manière à enfoncer les fils dans cette fente, en position transversale par rapport à elle, et qui vient prendre appui par un noyau de guidage dans la cavité interne de la partie profilée, ledit embout étant guidé en translation, vers la cavité et depuis l'extérieur du boîtier, par les bords d'un trou ménagé à cet effet dans ledit boîtier isolant.According to a characteristic of the invention, the slot is longitudinally formed along a profiled part of the conductive part which has, at this level, a hollow polygonal cross section allowing the guiding in translation, along the slot, of an external tool tip which is designed to slide both on either side and between the edges of the slot, so as to push the wires into this slot, in a transverse position relative to it, and which comes to take support by a guide core in the internal cavity of the profiled part, said endpiece being guided in translation, towards the cavity and from outside the housing, by the edges of a hole made for this purpose in said insulating housing.

Selon une autre caractéristique de l'invention, l'embout d'outil mécanique ou manuel, nécessaire à la connecxion d'un fil dans l'agencement de connexion selon l'invention, comporte un noyau rectiligne de guidage profilé transversalement pour venir coulisser simultanément à travers la fente conductrice de connexion au niveau de rainures qu'il comporte et dans la cavité interne de cette pièce où il se guide.According to another characteristic of the invention, the tip of a mechanical or manual tool, necessary for the connection of a wire in the connection arrangement according to the invention, comprises a core straight guide profiled transversely to slide simultaneously through the conductive connection slot at the level of grooves which it comprises and in the internal cavity of this part where it is guided.

L'invention, ses caractéristiques et ses avantages sont précisés dans la description qui suit, en liaison avec les figures répertoriées ci-dessous.The invention, its characteristics and its advantages are explained in the following description, in conjunction with the figures listed below.

La figure 1 présente un exemple d'équipement électrique doté de deux agencements de connexion selon l'invention et associé à deux outils de connexion selon l'invention pour le raccordement de fils électriques montrés l'un avant insertion l'autre en cours de connexion.FIG. 1 shows an example of electrical equipment provided with two connection arrangements according to the invention and associated with two connection tools according to the invention for the connection of electric wires shown one before insertion the other during connection .

La figure 5 présente une demi-vue en coupe selon V-V de l'équipement présenté figure 4.FIG. 5 presents a half-view in section along V-V of the equipment presented in FIG. 4.

Les figures 6 et 7 présentent une vue de dessus et une coupe selon VII-VII de la partie d'équipement présentée figure 5.Figures 6 and 7 show a top view and a section along VII-VII of the part of equipment presented in Figure 5.

La figure 8 présente une variante de la partie d'équipement présentée figure 4.FIG. 8 presents a variant of the part of equipment presented in FIG. 4.

Les figures 9 à 12 présentent des vues analogues à celles des figures 3, 5, 6 et 7 pour une variante de réalisation de l'embout d'outil de connexion et de l'équipement correspondant.Figures 9 to 12 show views similar to those of Figures 3, 5, 6 and 7 for an alternative embodiment of the connection tool tip and the corresponding equipment.

L'agencement de connexion à fente selon l'invention est destiné à être intégré dans un équipement électrique 1 pour assurer le raccordement d'un ou de plusieurs fils électriques 2 en parallèle à cet équipement, qui, dans l'exemple non limitatif présenté figure 1, est doté de deux agencements de connexion à fente dont les éléments internes essentiels sont en majeure partie dessinés en pointillé.The slot connection arrangement according to the invention is intended to be integrated into electrical equipment 1 to ensure the connection of one or more electrical wires 2 in parallel to this equipment, which, in the nonlimiting example presented in FIG. 1, is provided with two slot connection arrangements, the essential internal elements of which are mainly drawn in dotted lines.

Chaque agencement de connexion comporte une pièce conductrice de connexion 3 apte à recevoir au moins un et préférablement plusieurs fils électriques 2 en parallèle.Each connection arrangement comprises a conductive connection piece 3 capable of receiving at least one and preferably several electrical wires 2 in parallel.

Dans l'exemple proposé, les deux pièces conductrices 3 de l'équipement 1 sont susceptibles d'être électriquement mises en liaison par l'intermédiaire d'un organe contacteur 4, classique quine sera pas décrit plus avant dans la mesure où il n'a qu'un rapport facultatif et indirect avec l'invention.In the example proposed, the two conductive parts 3 of the equipment 1 are capable of being electrically connected by means of a contactor member 4, a conventional one which will not be described further since it does not has only an optional and indirect relationship with the invention.

Les pièces conductrices 3 sont immobilisées classiquement dans des logements prévus à cet effet dans le boîtier isolant 5 de l'équipement 1, qui est par exemple constitué par assemblage de deux demi-coques complémentaires rendues solidaires par soudage ultrasonique après introduction des organes internes qu'elles doivent contenir.The conductive parts 3 are conventionally immobilized in housings provided for this purpose in the insulating housing 5 of the equipment 1, which is for example constituted by assembling two complementary half-shells made integral by ultrasonic welding after introduction of the internal organs that they must contain.

Cet assemblage de demi-coques s'effectue par exemple avec pour plan de joint le plan longitudinal médian du boîtier 5 dont la trace partage également les vues des figures 4, 6, 7 et 8.This assembly of half-shells is carried out for example with the median longitudinal plane of the housing 5 as a joint plane, the trace of which also shares the views of FIGS. 4, 6, 7 and 8.

Chaque pièce conductrice 3 - figure 2 - comporte une fente 30 de dénudage et de retenue des âmes de fil, qui est ici rectiligne comme on le voit sur les figures 2 et 4. Cette fente est longitudinalement ménagée au long d'une partie en forme de profilé de la pièce 3, qui est ici obtenue, par exemple à partir d'un flan plan, par matricage entraînant sa découpe, son pliage et éventuellement des amincissements localisés.Each conductive piece 3 - Figure 2 - has a slot 30 for stripping and retaining the cores of wire, which is here rectilinear as seen in Figures 2 and 4. This slot is longitudinally formed along a shaped part profile of the part 3, which is obtained here, for example from a flat blank, by stamping resulting in its cutting, folding and possibly localized thinning.

La partie profilée de la pièce 3 a préférablement une section transversale polygonale creuse qui correspond ici à un U dont les extrémités libres ont été obliquement et également repliées l'une vers l'autre, comme on le voit sur les figures 2 et 7.The profiled part of the part 3 preferably has a hollow polygonal cross section which here corresponds to a U whose free ends have been obliquely and also folded towards one another, as seen in FIGS. 2 and 7.

La partie profilée ainsi obtenue comporte deux plis 31 d'extrémité correspondant aux extrémités libres obliquement et également repliées évoquées ci-dessus, ces deux plis bordent la fente 30 qu'ils délimitent, ils sont éventuellement amincis graduellement vers cette fente 30.The profiled part thus obtained comprises two end folds 31 corresponding to the free ends obliquely and also folded mentioned above, these two folds border the slot 30 which they delimit, they are optionally gradually thinned towards this slot 30.

Les deux parois parallèles 32 de la partie profilée de la pièce conductrice 3, qui portent chacune un pli 31, assurent l'immobilisation de cette pièce 3 dans son logement, conjointement avec la paroi de fond 33 dont elles sont issues et avec laquelle elles sont perpendiculaires ; cette immobilisation s'effectue par les moyens connus déjà évoqués brièvement plus haut.The two parallel walls 32 of the profiled part of the conductive part 3, which each carry a fold 31, ensure the immobilization of this part 3 in its housing, together with the bottom wall 33 from which they originate and with which they are perpendicular; this immobilization is carried out by the known means already mentioned briefly above.

L'embouchure dénudante 34 de la pièce conductrice est ménagée à une extrémité de la fente 30 ; il est aussi envisageable de prévoir des parties profilées dont la fente dénudante serait munie d'une embouchure dénudante à chaque extrémité pour former un agencement de connexion à deux entrées.The stripped mouth 34 of the conductive part is formed at one end of the slot 30; it is also conceivable to provide profiled parts whose stripping slot would be provided with a stripping mouth at each end to form a connection arrangement with two inputs.

Dans l'exemple proposé, la seule embouchure dénudante prévue est obtenue par découpe oblique symétrique des plis 31 à une de leur extrémité, qui est l'extrémité supérieure de la partie profilée sur les figures 1, 4, 5 et 8. Cette découpe oblique permet d'obtenir une embouchure évasée ; le pliage ultérieur des plis 31, par rapport aux parois 32 qui les portent respectivement, crée une arête supérieure 35 suffisante pour entamer la gaine des fils 2 poussés dans cette embouchure.In the example proposed, the only stripped mouth provided is obtained by symmetrical oblique cutting of the pleats 31 at one of their ends, which is the upper end of the profiled part in FIGS. 1, 4, 5 and 8. This oblique cutting provides a flared mouth; the subsequent folding of the folds 31, with respect to the walls 32 which carry them respectively, creates an upper edge 35 sufficient to start the sheath of the wires 2 pushed into this mouth.

Les parois parallèles 32, la paroi de fond 33 et les plis 31 délimitent une cavité 36 que l'on s'arrange à faire déboucher à l'extérieur par un trou 51 ménagé dans le boîtier 5, ici à la partie supérieure de ce dernier - figures 5 et 6 -.The parallel walls 32, the bottom wall 33 and the folds 31 delimit a cavity 36 which is arranged to open out through a hole 51 formed in the housing 5, here at the top of the latter - Figures 5 and 6 -.

Le trou 51 a ici une section transversale, ou profil, en T, la partie du trou 51 correspondant à la barre verticale du T - qui est horizontale sur la figure 6 - ayant une même largeur que la cavité 36 dans le prolongement de laquelle elle est placée.The hole 51 here has a cross section, or profile, in T, the part of the hole 51 corresponding to the vertical bar of the T - which is horizontal in Figure 6 - having the same width as the cavity 36 in the extension of which it is placed.

Le trou 51, qui est légèrement évasé à son bord ici supérieur donnant accès à l'extérieur, est conçu pour permettre l'introduction d'un embout d'outil de connexion 6 extérieur, indépendant, destiné à assurer l'insertion de fils électriques dans la fente 30 de l'agencement de connexion 3 et de tout agencement de connexion identique ou compatible.The hole 51, which is slightly flared at its upper edge here giving access to the outside, is designed to allow the introduction of an external connection tool tip 6, independent, intended to ensure the insertion of electric wires in the slot 30 of the connection arrangement 3 and of any identical or compatible connection arrangement.

L'embout d'outil 6 comporte en ce but un noyau de guidage 60 - (figures 1, 2 et 3) - rectiligne dont la section transversale a une forme complémentaire de celle de la cavité 36 dans laquelle il est destiné à venir coulisser après avoir été guidé vers elle par la partie du trou 51 situé dans le prolongement de cette cavité.The tool endpiece 6 has for this purpose a guide core 60 - (Figures 1, 2 and 3) - straight whose cross section has a shape complementary to that of the cavity 36 in which it is intended to slide after have been guided towards it by the part of the hole 51 located in the extension of this cavity.

Le noyau de guidage 60 est bordé latéralement par un renflement longitudinal 61 auquel il est relié par un voile rigide 62. Le voile 62 a une épaisseur légèrement inférieure à la largeur de la fente 30 à travers lequel il vient d'insérer, lorsque l'embout est introduit dans le boîtier 3, le noyau de guidage 60 assurant alors le positionnement correct du voile 62 par rapport à la fente 30.The guide core 60 is bordered laterally by a longitudinal bulge 61 to which it is connected by a rigid web 62. The web 62 has a thickness slightly less than the width of the slot 30 through which it has just inserted, when the tip is introduced into the housing 3, the guide core 60 then ensuring correct positioning of the web 62 relative to the slot 30.

Le renflement 61 vient coulisser le long et à l'extérieur des plis 31, comme le montre la figure 3 où la pièce conductrice 3 a été montrée en pointillé.The bulge 61 slides along and outside the folds 31, as shown in FIG. 3 where the conductive part 3 has been shown in dotted lines.

Le noyau 60, le renflement 61 et le voile 62 terminent l'embout d'outil 6 à un même niveau de manière à former une zone d'appui destinée à s'appliquer sur la gaine des fils électriques à connecter.The core 60, the bulge 61 and the veil 62 terminate the tool tip 6 at the same level so as to form a support zone intended to be applied to the sheath of the electrical wires to be connected.

Dans la forme de réalisation choisie, la section transversale de l'embout à la forme d'un T composé de deux éléments rectangulaires accolés dont les axes longitudinaux sont perpendiculaires, le noyau 60 correspondant à l'un de ces deux éléments alors que le renflement 61 correspond à l'autre, le voile étant obtenu par rainurage symétrique oblique de part et d'autre du noyau et dans le renflement. Chaque rainure 63 bordant le voile, court longitudinalement le long de l'embout depuis la zone d'appui et permet l'introduction de cet embout de manière que le voile 62 s'insère dans la fente 30 et que les plis 31 s'insèrent dans les rainures 63.In the embodiment chosen, the cross section of the endpiece in the shape of a T made up of two adjoining rectangular elements whose longitudinal axes are perpendicular, the core 60 corresponding to one of these two elements while the bulge 61 corresponds to the other, the veil being obtained by symmetrical oblique grooving on either side of the core and in the bulge. Each groove 63 bordering the veil, runs longitudinally along the end piece from the support zone and allows the introduction of this end piece so that the veil 62 is inserted into the slot 30 and that the folds 31 are inserted in the grooves 63.

Dans la forme de réalisation choisie le trou 51 a une section transversale en T qui correspond précisément à celle de l'embout de manière à guider ce dernier, tant vers la pièce 3 que dans son coulissement le long de cette pièce 3.In the embodiment chosen, the hole 51 has a cross section in T which corresponds precisely to that of the end piece so as to guide the latter, both towards the part 3 and in its sliding along this part 3.

Bien entendu l'embout d'outil 6, ici monté à l'extrémité d'une tige cylindrique, est susceptible d'être adapté sur différents appareils mécaniques fixes ou portatifs pour le montage en usine ou sur chantier, il peut également être prévu sur un outil manuel, il suffit pour se faire de le monter à l'extrémité d'un manche.Of course the tool tip 6, here mounted at the end of a cylindrical rod, is capable of being adapted to different fixed or portable mechanical devices for mounting in the factory or on site, it can also be provided on a hand tool, it suffices to mount it at the end of a handle.

Bien entendu dans le cas d'un outil mécanique, la tige est mue mécaniquement, hydrauliquement ou pneumatiquement dans un corps d'outil qui préférablement est rendu temporairement solidaire de l'équipement 1 comportant l'agencement de connexion concerné, si ce n'est de cet agencement lui même, par tout moyen connu.Of course in the case of a mechanical tool, the rod is moved mechanically, hydraulically or pneumatically in a tool body which preferably is made temporarily secured to the equipment 1 comprising the connection arrangement concerned, if not of this arrangement itself, by any known means.

L'introduction d'un fil électrique à connecter s'effectue par l'intermédiaire d'une ouverture qui s'ouvre en regard de la fente 30 dans une paroi extérieure 50 du boîtier 5, cette ouverture est destinée à permettre l'introduction d'un fil électrique 2 au-dessus de l'embouchure dénudante 34 (figure 4) et elle comporte un orifice cylindrique 52, à travers lequel il est possible d'enfoncer axialement un fil jusqu'à ce qu'il vienne en butée sur la paroi de fond 33 de la pièce conductrice 3.The introduction of an electrical wire to be connected is effected via an opening which opens opposite the slot 30 in an outer wall 50 of the housing 5, this opening is intended to allow the introduction of '' an electric wire 2 above the mouthpiece stripping 34 (FIG. 4) and it has a cylindrical orifice 52, through which it is possible to axially insert a wire until it comes into abutment on the bottom wall 33 of the conductive part 3.

L'orifice 52 est fendu à sa partie inférieure de manière à déboucher au sommet d'une lumière rectiligne 53, de l'ouverture précitée, qui s'étend au droit de la fente 30.The orifice 52 is slit at its lower part so as to open at the top of a rectilinear lumen 53, from the abovementioned opening, which extends in line with the slot 30.

Cette lumière rectiligne 53 est destinée à assurer la retenue des gaines des fils connectés, elle a donc une largeur légèrement inférieure au diamètre de la plus petite des gaines prévues, de même que la fente 30 a une largeur légèrement inférieure au diamètre de la plus petite des âmes prévues pour les fils.This rectilinear light 53 is intended to ensure the retention of the sheaths of the connected wires, it therefore has a width slightly less than the diameter of the smallest of the sheaths provided, just as the slot 30 has a width slightly less than the diameter of the smallest souls planned for the sons.

Dans la forme de réalisation présentée deux lumières auxiliaires 54 bordent latéralement la lumière rectiligne 53, de manière à permettre la déformation des zones du boîtier, qui assurent le coincement des gaines de fil, lorsque ces gaines sont insérées, sans que pour cela les formes extérieures du boîtier 5 soient modifiées, ce qui est particulièrement important dans le cas de boîtiers accolés.In the embodiment presented two auxiliary lights 54 laterally border the rectilinear light 53, so as to allow the deformation of the areas of the housing, which ensure the jamming of the wire sheaths, when these sheaths are inserted, without this for the external forms of the housing 5 are modified, which is particularly important in the case of contiguous housings.

Dans une variante de réalisation présentée figure 8, dans laquelle les éléments identiques ou similaires à ceux présentés figure 4 portent les mêmes références numériques affectées d'un signe prime, les lumières auxiliaires 54′ sont séparées de la lumière rectiligne 53′ par des parois 55′ plus minces, depuis l'orifice 52′ d'insertion de fil jusqu'au dessous du niveau de l'embouchure dénudante 34′, que pour les parties qui se poursuivent, depuis ce niveau vers le fond des lumières, de manière à réduire l'effort de déplacement de la gaine d'un fil dans la lumière rectiligne 53′ pendant la coupe de cette gaine par l'embouchure dénudante 34′.In an alternative embodiment presented in FIG. 8, in which the elements identical or similar to those presented in FIG. 4 bear the same numerical references assigned a prime sign, the auxiliary lights 54 ′ are separated from the rectilinear light 53 ′ by walls 55 ′ Thinner, from the hole 52 ′ for inserting the wire to below the level of the stripping mouth 34 ′, than for the parts which continue, from this level towards the bottom of the lights, so as to reduce the effort of displacement of the sheath of a wire in the rectilinear lumen 53 ′ during the cutting of this sheath by the stripping mouth 34 ′.

La connexion d'un fil électrique 2 s'effectue selon un processus suivant lequel on enfile axialement une extrémité de ce fil, non dénudé, à travers l'orifice 52 prévu à cet effet dans le boîtier 5 (figure 5). Lorsque le fil 2 vient en butée contre la paroi de fond 33 de la pièce conductrice 3, on introduit l'embout d'un outil 6 dans le trou 51 qui le guide.The connection of an electric wire 2 is carried out according to a process according to which an end of this wire, not stripped, is threaded axially through the orifice 52 provided for this purpose in the housing 5 (FIG. 5). When the wire 2 abuts against the bottom wall 33 of the conductive part 3, the tip of a tool 6 is introduced into the hole 51 which guides it.

L'extrémité d'embout vient en appui sur le fil 2 qui est transversalement poussé vers l'embouchure dénudante de la pièce conductrice 3 ; cette embouchure entraîne la gaine 20 du fil 2, dont l'âme 21 vient s'insérer dans la fente entre les bords des plis 31.The end of the end piece bears on the wire 2 which is transversely pushed towards the stripped mouth of the conductive part 3; this mouthpiece drives the sheath 20 of the wire 2, the core 21 of which is inserted into the slot between the edges of the folds 31.

La longueur de l'embout d'outil 6 permet l'insertion d'un premier fil 2 en fond de fente, tel le fil référencé 2A présenté en pointillé sur la figure 5.The length of the tool tip 6 allows the insertion of a first wire 2 at the bottom of the slot, such as the wire referenced 2A presented in dotted lines in FIG. 5.

Lors de l'enfoncement d'un fil 2 transversalement à la fente sous l'action de l'embout, la gaine 20 de ce fil est entraînée dans la lumière rectiligne 53 (ou 53′) et le fil est maintenu en fin d'enfoncement par la lumière 53 au niveau de sa gaine, et par la fente 30, au niveau de son âme.When driving a wire 2 transversely to the slot under the action of the tip, the sheath 20 of this wire is entrained in the rectilinear lumen 53 (or 53 ′) and the wire is held at the end of depression by the light 53 at its sheath, and by the slot 30, at its soul.

Il est également prévu, en variante non représentée, de doter l'embout d'outil 6 d'un élément de poussée venant au niveau de l'extrémité d'appui de cet embout à l'extérieur du boîtier 5, pour appuyer simultanément à l'intérieur et à l'extérieur du boîtier sur la gaine d'un fil lors du raccordement.It is also planned, in a variant not shown, to endow the tool endpiece 6 with a pushing element coming at the level of the bearing end of this endpiece outside the housing 5, to simultaneously press on inside and outside the housing on the sheath of a wire during connection.

Après immobilisation d'un fil, l'embout d'outil est ressorti du boîtier 5, en totalité en cas de raccordement d'un fil unique, ou éventuellement partiellement en entrée de trou 51 si l'on veut raccorder un ou plusieurs autres fils dans la même fente de pièce conductrice 3.After immobilizing a wire, the tool endpiece has emerged from the housing 5, entirely in the event of connection of a single wire, or possibly partially at the hole inlet 51 if one wants to connect one or more other wires. in the same conductive part slot 3.

Les figures 8 à 11 proposent une variante de réalisation prévue pour permettre l'emploi d'un outil dont l'embout 6˝ a un profil transversal symétrique, ainsi qu'on le voit sur la figure 12, afin d'éviter d'avoir à tourner l'outil de 180° lorsque l'on raccorde successivement des fils à des pièces conductrices montées dos à dos comme le montre la figure 1 pour les pièces conductrices 3.Figures 8 to 11 propose an alternative embodiment provided to allow the use of a tool whose tip 6˝ has a symmetrical transverse profile, as seen in Figure 12, to avoid having to turn the tool 180 ° when successively connecting wires to conductive parts mounted back to back as shown in Figure 1 for conductive parts 3.

Le noyau de guidage 60˝ de l'embout d'outil 6˝, montré sur les figures 9 et 12, est rainuré symétriquement de même que l'était le noyau 60 de manière à pouvoir coulisser entre les plis 31˝ délimitant la fente d'une pièce de connexion telle que 3˝.The guide core 60˝ of the tool end 6˝, shown in Figures 9 and 12, is symmetrically grooved as was the core 60 so as to be able to slide between the folds 31˝ delimiting the slot d 'a connecting piece such as 3˝.

Le guidage de l'embout d'outil 6˝ pour l'insertion d'un fil 2˝ dans une pièce de connexion telle que 3˝ -figure 9- est assuré par l'un ou l'autre de deux demi-noyaux 60˝ symétriques destinés alternativement l'un à pénétrer dans la section transversale polygonale creuse de la pièce conductrice 3 le long de sa fente de dénudage et de maintien de fil, l'autre à coulisser à l'extérieur de cette fente, dans le boîtier isolant 5˝ qui contient ladite pièce conductrice 3˝.The guide of the tool tip 6˝ for the insertion of a wire 2˝ in a connection piece such as 3˝ -figure 9- is ensured by one or the other of two half-cores 60 ˝ symmetrical alternately intended one to penetrate into the hollow polygonal cross section of the conductive piece 3 along its stripping and wire holding slot, the other to slide outside of this slot, in the housing insulator 5˝ which contains said conductive part 3˝.

Dans l'exemple de réalisation l'embout d'outil est constitué par un corps d'allure parallélipipédique rectangle centré sur l'axe longitudinal médian de l'embout 6˝ dans l'épaisseur et de part et d'autre duquel sont ménagées les rainures 63˝.In the exemplary embodiment, the tool endpiece is constituted by a body of rectangular parallelepipedal shape centered on the median longitudinal axis of the endpiece 6˝ in the thickness and on either side of which the grooves 63˝.

L'équipement 1˝ qui est par exemple un bloc de jonction, comporte au moins une paire de pièces conductrices 3˝ à fente dont une seule est représentée ; ces pièces sont montées dos à dos et reliées entre elles, ici pour une barrette commune 4˝, l'ensemble est logé dans un boîtier isolant 5˝ permettant d'une part l'introduction de fils électriques à raccorder, d'autre part l'introduction d'un embout d'outil 6˝.The equipment 1˝ which is for example a terminal block, comprises at least one pair of conductive parts 3˝ with a slot of which only one is shown; these parts are mounted back to back and connected together, here for a common strip 4˝, the assembly is housed in an insulating housing 5˝ allowing on the one hand the introduction of electrical wires to be connected, on the other hand l 'introduction of a tool tip 6˝.

Les pièces de connexion 3˝ et le boîtier isolant 5˝ se différencient essentiellement de ceux présentés précédemment par l'encombrement plus réduit desdites pièces de connexion et par la forme de l'ouverture d'introduction d'outil. Cette dernière se présente ici sous forme d'un trou à section rectangulaire destiné à conduire l'embout d'outil en une position précise, prédéterminée par rapport à la pièce de connexion 3′ que ce trou surplombe.The connection pieces 3˝ and the insulating housing 5˝ differ essentially from those presented above by the smaller size of said connection pieces and by the shape of the tool introduction opening. The latter is here in the form of a hole of rectangular section intended to drive the tool endpiece into a precise position, predetermined with respect to the connection piece 3 ′ that this hole overhangs.

Le raccordement d'un fil s'effectue selon le même processus que celui déjà évoqué plus haut.The connection of a wire is carried out according to the same process as that already mentioned above.
