Description

La présente invention a pour objet un agencement de connexion, du type à fente dénudante assurant le raccordement électrique et l'immobilisation d'au moins un fil électrique gainé d'isolant, sans exiger de dénudage préalable de ce fil.The subject of the present invention is a connection arrangement, of the stripping slot type ensuring the electrical connection and immobilization of at least one electric wire sheathed in insulation, without requiring prior stripping of this wire.

De tels agencements de connexion sont habituellement mis en oeuvre pour raccorder des fils entre eux, par exemple dans des organes de type bloc de jonction, ou pour raccorder des fils à un équipement électrique, tel qu'un organe de commande.Such connection arrangements are usually used to connect wires together, for example in members of the junction block type, or to connect wires to electrical equipment, such as a control member.

Classiquement chaque agencement de connexion comporte une fente dénudante, ménagée dans une pièce conductrice de faible épaisseur ; cette fente est dotée, à l'une de ses extrémités, d'une embouchure évasée destinée à faciliter l'insertion longitudinale dans la fente du fil à raccorder, qui est disposé transversalement, et à assurer simultanément, en début d'insertion, une coupe transversale de l'isolant gainant ce fil.Conventionally, each connection arrangement comprises a stripping slot, formed in a conductive piece of small thickness; this slot is provided, at one of its ends, with a flared mouth intended to facilitate longitudinal insertion into the slot of the wire to be connected, which is arranged transversely, and to simultaneously ensure, at the start of insertion, cross section of the insulation sheathing this wire.

L'âme du fil localement dénudée par l'embouchure, vient en contact avec les bords de fente qui l'immobilisent par leur pression et qui assurent simultanément une continuité électrique entre ce fil et la pièce conductrice.The core of the wire locally stripped by the mouth, comes into contact with the slot edges which immobilize it by their pressure and which simultaneously provide electrical continuity between this wire and the conductive part.

L'insertion d'un fil électrique dans une fente dénudante s'effectue avantageusement à l'aide d'une pièce auxiliaire qui est incorporée dans le bloc ou l'équipement et qui force le fil dans le fente à travers l'embouchure dénudante de cette dernière. Pour des raisons de commodité et d'efficacité on s'arrange souvent pour pousser la pièce auxiliaire d'insertion à l'aide d'un outil permettant d'avoir une meilleure prise et éventuellement un effet démultiplicateur de manière à faciliter les opérations de raccordement.The insertion of an electric wire into a stripping slot is advantageously carried out using an auxiliary part which is incorporated in the block or the equipment and which forces the wire into the slot through the stripping mouth of the latter. For reasons of convenience and efficiency, we often manage to push the auxiliary insertion part using a tool allowing a better grip and possibly a multiplier effect so as to facilitate connection operations. .

Toutefois le positionnement des agencements de connexion dans leur environnement d'exploitation ne permet pas toujours le passage et la manipulation d'un outil dans de bonnes conditions, en raison notamment de la concentration et de l'imbrication des organes ou équipements comportant ces agencements de connexion, ou de la profusion de fils qui les entoure.However, the positioning of the connection arrangements in their operating environment does not always allow the passage and manipulation of a tool in good conditions, due in particular to the concentration and the nesting of the organs or equipment comprising these arrangements of connection, or the profusion of wires surrounding them.

En conséquence la présente invention propose un agencement de connexion à fente dénudante, pour fil électrique, comportant une pièce annulaire d'insertion de fil, actionnable par effet de levier, qui soit simple, aisée à manipuler et qui n'occupe qu'un volume réduit dans le bloc ou l'équipement qui l'incorpore.Consequently, the present invention provides an arrangement of stripped slot connection, for electrical wire, comprising an annular wire insertion part, actuated by lever effect, which is simple, easy to handle and which occupies only a reduced volume in the block or the equipment which incorporates it.

L'agencement de connexion à fente dénudante, pour fil électrique, comprend une pièce conductrice, à fente dotée d'une embouchure dénudante, qui est logée dans un boîtier doté d'une ouverture de passage de fil parallèle à la fente dénudante et d'une ouverture de passage pour une tige amovible formant levier qui est chargée de mouvoir une pièce auxiliaire d'insertion de fil, logée dans le boîtier et elle même chargée de presser une extrémité du fil électrique à connecter dans la fente, à travers son embouchure dénudante et transversalement à elle, jusqu'à une position où l'âme du fil est immobilisée entre les bords de fente, en contact électrique avec la pièce conductrice.The stripping slit connection arrangement for electrical wire comprises a conductive slit piece provided with a stripping mouth, which is housed in a housing provided with a wire passage opening parallel to the stripping slit and a passage opening for a removable rod forming a lever which is responsible for moving an auxiliary wire insertion part, housed in the housing and itself responsible for pressing one end of the electric wire to be connected into the slot, through its stripped mouth and transversely to it, to a position where the core of the wire is immobilized between the slit edges, in electrical contact with the conductive part.

Selon une caractéristique de l'invention, la pièce auxiliaire d'insertion, dotée d'un corps de manoeuvre traversé par un conduit de passage de tige et portant un poussoir pour le fil, comporte aussi un dispositif de guidage à galets coopérant avec deux rainures de guidage complémentaires du boîtier pour donner un mouvement pseudo-circulaire à ladite pièce auxiliaire d'insertion, sous la poussée latérale de la tige qui traverse le conduit pour s'appuyer dans un trou fixe solidaire du boîtier et servant de point d'appui, de manière que le poussoir passe alternativement d'une position inclinée, dite d'introduction, pour laquelle il permet l'insertion d'un fil électrique à travers l'orifice au dessus de l'embouchure dénudante, à une position, dite d'insertion, où l'extrémité d'appui de ce poussoir vient se placer sous le niveau de l'embouchure dénudante, perpendiculairement à la fente en appui sur un fil coincé par son âme entre les bords parallèles de fente, en cas de connexion d'un fil au moyen dudit agencement.

According to a characteristic of the invention, the auxiliary insertion part, provided with an operating body crossed by a rod passage duct and carrying a push rod for the wire, also comprises a roller guide device cooperating with two grooves complementary guidance of the housing to give a pseudo-circular movement to said auxiliary insertion part, under the lateral thrust of the rod which passes through the duct to rest in a fixed hole secured to the housing and serving as a fulcrum, so that the pusher alternately passes from an inclined position, called the insertion position, for which it allows the insertion of an electric wire through the orifice above the stripped mouth, to a position, called the insertion, where the bearing end of this pusher comes to be placed below the level of the stripped mouth, perpendicular to the slot bearing on a wire wedged by its core between the parallel edges of the slot, in the case of connection of a thread u by means of said arrangement.

Chaque pièce conductrice 3 est une pièce métallique qui comporte - voir figure 5 - une fente allongée délimitée par deux bords 30 parallèles sur la plus grande partie de leur longueur et à l'exception d'au moins une extrémité de le fente où ces bords s'évasent pour former une embouchure destinée à faciliter l'insertion d'un fil électrique 2 dans la fente et à assurer une coupure transversale de la gaine 20 de ce fil.Each conductive part 3 is a metal part which comprises - see FIG. 5 - an elongated slot delimited by two parallel edges 30 over most of their length and with the exception of at least one end of the slot where these edges s flare to form a mouthpiece intended to facilitate the insertion of an electric wire 2 into the slot and to ensure a transverse cut of the sheath 20 of this wire.

La paroi de fond 33 est bordée latéralement par deux parois parallèles qui lui sont perpendiculaires et qui se prolongent chacune par une paroi oblique 34 dont la bordure longitudinale externe constitue un bord 30 de fente, ces cinq parois délimitent la portion tubulaire de la pièce de connexion et forment une pince à ressort, à section grossièrement en C, dont les bords 30 forment les mors et sont susceptibles de coincer élastiquement entre eux un ou plusieurs fils électriques 2 par leurs âmes conductrices respectives 21.The bottom wall 33 is bordered laterally by two parallel walls which are perpendicular to it and which each extend by an oblique wall 34, the external longitudinal edge of which forms a slot edge 30, these five walls delimit the tubular portion of the connection piece and form a spring clip, with a roughly C section, the edges 30 of which form the jaws and are capable of elastically wedging between them one or more electric wires 2 by their respective conductive cores 21.

L'un des prolongements référencé 31 est replié, ici perpendiculairement, à l'opposé de la portion tubulaire de la pièce conductrice 3 par rapport à la paroi de fond 33 de cette pièce conduc- tr.ice, il est ici conçu pour recevoir un pion de contact 35 pour le contacteur 6 ainsi qu'on le voit figure 1.One of the extensions referenced 31 is folded, here perpendicularly, opposite the tubular portion of the conductive piece 3 relative to the bottom wall 33 of this conductive piece, it is here designed to receive a contact pin 35 for the contactor 6 as seen in Figure 1.

Le second des prolongements référencé 32 est traversé par un trou 36 fixe destiné à permettre la pénétration d'une pointe de tige d'outil 5, ce dernier étant par exemple un tournevis de type cruciforme. Dans la forme de réalisation présentée, le prolongement 32 est cambrée vers l'arrière par exemple de π/4 par rapport à sa position initiale dans l'alignement de la paroi de fond 33, avant cambrage, d'une manière qui l'éloigne de la portion tubulaire.The second of the extensions referenced 32 is crossed by a fixed hole 36 intended to allow the penetration of a tool rod tip 5, the latter being for example a Phillips-type screwdriver. In the embodiment presented, the extension 32 is arched backwards for example by π / 4 relative to its initial position in alignment with the bottom wall 33, before arching, in a manner which moves it away of the tubular portion.

Dans l'exemple présenté figure 1, les deux pièces conductrices 3 sont identiques et disposées symétriquement par rapport aux plans médians, l'un transversal, l'autre longitudinal, du boîtier 7 qui les contient, avec leurs premiers prolongements 31 alignés et orientés l'un vers l'autre, de manière que les fentes dénudantes qu'ils comportent soient orientées vers les petits côtés 70, verticaux sur la figure 1, dudit boîtier 7.In the example shown in Figure 1, the two conductive parts 3 are identical and arranged symmetrically with respect to the median planes, one transverse, the other longitudinal, of the housing 7 which contains them, with their first extensions 31 aligned and oriented l towards each other, so that the stripping slots which they comprise are oriented towards the short sides 70, vertical in FIG. 1, of said housing 7.

Comme indiqué précédemment les bords 30 délimitant la fente d'une pièce conductrice 3, s'évasent pour former une embouchure à l'une des extrémités de cette fente qui traverse longitudinalement la portion tubulaire de cette pièce conductrice parallèlement à la paroi de fond 33 et à l'axe longitudinal médian de cette paroi de fond.As indicated above, the edges 30 delimiting the slot of a conductive part 3, widen to form a mouth at one of the ends of this slot which extends longitudinally through the tubular portion of this conductive part parallel to the bottom wall 33 and to the median longitudinal axis of this bottom wall.

Dans la forme de réalisation choisie, c'est le second prolongement 32 auprès duquel est réalisé l'embouchure évasée. Cette dernière est destinée, comme on l'a vu, d'une part à guider les fils 2 à raccorder dans la fente et d'autre part à couper l'isolant de ces fils de manière à dénuder leur âme pour permettre l'établissement d'une continuité électrique de cette dernière avec la pièce conductrice qui l'enserre entre ses bords de fente 30, lorsque le fil concerné à été forcé dans ladite fente à travers l'embouchure.In the embodiment chosen, it is the second extension 32 with which the flared mouth is made. The latter is intended, as we have seen, on the one hand to guide the wires 2 to be connected in the slot and on the other hand to cut the insulation of these wires so as to strip their core to allow establishment electrical continuity of the latter with the conductive part which encloses it between its slot edges 30, when the wire concerned has been forced into said slot through the mouth.

De manière connue, montrée en figure 5, chaque petit côté 70 est doté d'une ouverture de passage de fil 71 s'étendant parallèlement aux bords de fente 30 de la pièce conductrice 3 voisine. L'ouverture de passage de fil 71 comporte une fente 71A qui s'étend tout au long des bords de fente 30 et qui est destinée à immobiliser la gaine isolante 20 des fils électriques 2 dont l'âme 21 est coincée entre les bords de fente 30, elle a donc une largeur inférieure aux diamètres prévus pour ces gaines isolantes.In known manner, shown in FIG. 5, each short side 70 is provided with a wire passage opening 71 extending parallel to the slot edges 30 of the adjacent conductive part 3. The wire passage opening 71 has a slot 71A which extends along the edges of the slot 30 and which is intended to immobilize the insulating sheath 20 of the electrical wires 2, the core 21 of which is wedged between the edges of the slot 30, it therefore has a width less than the diameters provided for these insulating sheaths.

L'ouverture de passage de fil 71 comporte aue-si un orifice 71B d'introduction de fil débouchant latéralement dans la fente qu'il comporte au dessus de l'embouchure évasée de manière à permettre l'introduction d'un fil 2 perpendiculairement à la paroi de fond 33 de la pièce conductrice'3 à travers le petit côté 70 concerné. Cet orifice 71B a bien entendu une ouverture permettant la libre introduction des fils sans effort jusqu'à leur butée contre la paroi de fond 33.The wire passage opening 71 comprises aue-if a wire introduction orifice 71B opening laterally into the slot which it has above the flared mouth so as to allow the introduction of a wire 2 perpendicular to the bottom wall 33 of the conductive piece 3 through the short side 70 concerned. This orifice 71B naturally has an opening allowing the free introduction of the wires without effort up to their abutment against the bottom wall 33.

Dans l'exemple de réalisation présenté figure 5, deux rainures 72 bordent l'ouverture de passage de fil 71 au niveau de sa fente 71A pour permettre la déformation des bords de cette fente 71A sans déformation générale du boîtier 70.In the embodiment shown in FIG. 5, two grooves 72 border the wire passage opening 71 at its slot 71A to allow the edges of this slot 71A to be deformed without general deformation of the housing 70.

Dans l'exemple présenté figure 1, les deux pièces auxiliaires d'insertion 4 sont identiques et sont susceptibles d'occuper des positions symétriques tant par rapport au plan médian longitudinal qu'au plan médian transversal du boîtier 7 qui les contient.In the example shown in Figure 1, the two auxiliary insertion parts 4 are identical and are likely to occupy symmetrical positions both with respect to the longitudinal median plane and to the transverse median plane of the housing 7 which contains them.

Chaque pièce auxiliaire d'insertion 4 comporte essentiellement - figures 2 à 4 -, un poussoir 40 destiné à venir' presser sur le fil à insérer, un corps de manoeuvre 41 qui porte le poussoir et qui est traversé par un conduit 42 de passage de tige 5 et un dispositif de guidage 43, constitué ici par deux paires de galets alignés, répartis de part et d'autre du poussoir sur le corps de manoeuvre.Each auxiliary insertion part 4 essentially comprises - FIGS. 2 to 4 -, a pusher 40 intended to come to press on the wire to be inserted, an operating body 41 which carries the pusher and which is crossed by a conduit 42 for passage of rod 5 and a guide device 43, here constituted by two pairs of aligned rollers, distributed on either side of the pusher on the operating body.

Selon l'invention, chaque pièce auxiliaire d'introduction 4, qui est susceptible de se mouvoir pour permettre l'insertion d'un fil, via un orifice 71B, au dessus de l'embouchure évasée de la pièce conductrice 3 qu'elle dessert et pour assurer l'insertion de ce fil dans la fente dénudante de cette pièce conductrice, est agencée et montée de manière à permettre l'introduction et l'insertion de fil par un déplacement de faible amplitude de la tige 5 utilisée en tant que levier, tout en assurant un mouvement du poussoir suffisamment ample pour permettre l'introduction du fil devant l'embouchure évasée de la pièce conductrice et l'insertion de ce fil dans la fente, la pièce auxiliaire d'insertion n'exigeant qu'un volume vide réduit dans le boîtier pour son déplacement.According to the invention, each auxiliary introduction part 4, which is capable of moving to allow the insertion of a wire, via an orifice 71B, above the flared mouth of the conductive part 3 which it serves and to ensure the insertion of this wire into the stripping slot of this conductive part, is arranged and mounted so as to allow the introduction and insertion of wire by a small amplitude displacement of the rod 5 used as a lever , while ensuring sufficient movement of the pusher to allow the introduction of the wire in front of the flared mouth of the conductive part and the insertion of this wire into the slot, the auxiliary insertion part requiring only a volume reduced vacuum in the housing for its movement.

En ce but les galets du dispositif de guidage 43 viennent se loger dans deux rainures de guidage 73 complémentaires qui sont identiquement ménagées dans les parois internes des deux grands côtés parallèles 74 du boîtier 7, à proximité du bout 75 de ce boîtier.For this purpose the rollers of the guide device 43 are housed in two complementary guide grooves 73 which are identically formed in the internal walls of the two large parallel sides 74 of the housing 7, near the end 75 of this housing.

Dans l'exemple de réalisation présenté, chaque rainure de guidage 73 est ménagée au dessus de l'emplacement prévu pour immobiliser la portion tubulaire d'une pièce conductrice 3 dans le boîtier 7 et elle est formée de deux zones successives distinctes.In the embodiment shown, each guide groove 73 is formed above the location provided for immobilizing the tubular portion of a conductive part 3 in the housing 7 and it is formed of two separate successive zones.

Une première zone de rainure de guidage 73 - figures 6, 7 -est légèrement courbe et possède une orientation au moins approximativement parallèle à la fente dénudante de la pièce conductrice 3 qu'elle surplombe dans le boîtier 7, à pratiquement mi-distance entre cette fente et la paroi de fond 33 de ladite pièce conductrice 3.A first guide groove zone 73 - Figures 6, 7 -is slightly curved and has an orientation at least approximately parallel to the stripping slot of the conductive part 3 which it overhangs in the housing 7, at practically mid-distance between this slot and the bottom wall 33 of said conductive part 3.

Une seconde zone de rainure de guidage, qui débouche dans la première zone, est largement inclinée et a une orientation voisine de celle du second prolongement 32 de la pièce conductrice 3 qu'elle surplombe, en se rapprochant de ce prolongement au niveau de leurs extrémités respectives ; dans l'exemple de réalisation présenté où le second prolongement fait un angle de 11/4 avec la paroi de fond 33 et donc avec la fente, la seconde zone de rainure à son axe longitudinal incliné d'environ 7 π/18, ce qui autorise une faible hauteur de bloc, pour le logement de la pièce auxiliaire d'insertion 4 et permet un basculement accéléré de la pièce auxiliaire.A second guide groove zone, which opens into the first zone, is widely inclined and has an orientation close to that of the second extension 32 of the conductive part 3 which it overhangs, approaching this extension at their ends. respective; in the example of embodiment presented where the second extension makes an angle of 11/4 with the bottom wall 33 and therefore with the slot, the second groove zone at its inclined longitudinal axis of approximately 7 π / 18, which allows a low block height, for housing the auxiliary insertion part 4 and allows accelerated tilting of the auxiliary part.

Chacun des deux galets du dispositif de guidage 43 d'une pièce auxiliaire d'insertion, qui sont situés du même côté de cette pièce, vient se loger dans une zone différente de la rainure de guidage 73 qu'ils partagent et la pièce auxiliaire d'insertion est soumise à une pseudo-rotation, qui fait basculer son poussoir 40 depuis une position inclinée, dite d'introduction, pour laquelle l'un des galets est en fond de seconde zone de rainure et dans laquelle l'orifice 71B est totalement dégagé de toute obstruction par le poussoir 40 de la pièce auxiliaire d'insertion concernée (figure 6), jusqu'à une position, dite d'insertion, ou ce poussoir 40 vient se placer derrière l'orifice 71B, perpendiculairement à la fente dénudante, à la hauteur de la zone où les bords 30 parallèles de cette fente s'évasent pour former l'embouchure dénudante.Each of the two rollers of the guide device 43 of an auxiliary insertion part, which are located on the same side of this part, is housed in a different zone from the guide groove 73 which they share and the auxiliary part d insertion is subjected to a pseudo-rotation, which causes its pusher 40 to tilt from an inclined position, called the introduction position, for which one of the rollers is at the bottom of the second groove zone and in which the orifice 71B is completely cleared of any obstruction by the pusher 40 of the auxiliary insertion part concerned (FIG. 6), to a position, called the insertion position, or this pusher 40 is placed behind the orifice 71B, perpendicular to the stripping slot , at the height of the zone where the parallel edges 30 of this slot flare to form the stripped mouth.

Ainsi qu'on le voit sur les figures 6 et 7, les galets du dispositif de guidage 43 qui sont alignés et qui coulissent dans les premières zones de deux rainures de guidage complémentaires 73 sont préférablement positionnés entre le poussoir 40 et le conduit 42 de passage de tige amovible.As can be seen in FIGS. 6 and 7, the rollers of the guide device 43 which are aligned and which slide in the first zones of two complementary guide grooves 73 are preferably positioned between the pusher 40 and the passage duct 42 removable rod.

Dans la forme de réalisation présentée chaque pièce auxiliaire d'insertion 4 est dotée d'une butée 44 venant s'appliquer contre une contre-butée 76 du boîtier 7 en fin de course, lorsque le poussoir a son extrémité au niveau du bas de l'embouchure dénudante.In the embodiment presented, each auxiliary insertion part 4 is provided with a stop 44 which comes to bear against a counter-stop 76 of the housing 7 at the end of the stroke, when the pusher has its end at the bottom of the stripped mouth.

De plus un index 45, ici placé sous la butée et constitué par une petite tige moulée avec la pièce auxiliaire d'insertion, est disposé de manière à être visible à travers l'orifice 71B du boîtier, lorsque la pièce auxiliaire d'insertion est appuyée sur la contre-butée.In addition, an index 45, here placed under the stop and constituted by a small rod molded with the auxiliary insertion part, is arranged so as to be visible through the orifice 71B of the housing, when the auxiliary insertion part is supported on the counter-stop.

Le conduit 42 ménagé dans chaque pièce auxiliaire d'insertion 4 est disposé obliquement par rapport au poussoir 40, de manière que son orifice, débouchant à proximité du second prolongement 32 de la pièce conductrice 3 correspondante, soit toujours en regard du trou 36 prévu dans ce second prolongement 32 pour recevoir l'extrémité pointue de la tige 5 et cela quelle que soit la position de la' pièce auxiliaire d'insertion 4 dans le boîtier 7.The conduit 42 formed in each auxiliary insertion part 4 is disposed obliquely with respect to the pusher 40, so that its orifice, opening near the second extension 32 of the corresponding conductive part 3, is always opposite the hole 36 provided in this second extension 32 for receiving the pointed end of the rod 5 and this irrespective of the position of the auxiliary insertion part 4 in the housing 7.

Le conduit 42 débouche par un second orifice au dessus de la butée 44 et au niveau d'une ouverture de passage 77 ménagée à la partie supérieure 75 de ce bloc pour permettre l'introduction de la tige 5 dans le bloc et son débattement angulaire lors du déplacement de la pièce auxiliaire d'insertion 4 à l'intérieur du boîtier 7.The conduit 42 opens through a second orifice above the stop 44 and at the level of a passage opening 77 formed in the upper part 75 of this block to allow the introduction of the rod 5 into the block and its angular movement during displacement of the auxiliary insertion part 4 inside the housing 7.

De manière connue en soi, la ou les pièces auxiliaires d'insertion 4 et la ou les pièces conductrices 3 sont enfermées dans le boîtier de l'équipement électrique lors de la réalisation de ce dernier.In a manner known per se, the auxiliary insertion part or parts 4 and the conductive part or parts 3 are enclosed in the casing of the electrical equipment during the production of the latter.

Chaque pièce auxiliaire 4 est positionnée en position ouverte avant insertion d'un fil électrique 2, l'orifice 71B est alors dégagé, elle est maintenue en cette position par accrochage d'un cran 46 qu'elle porte sur un rebord 77 interne au boîtier comme le montre la figure 6 dans l'exemple de réalisation présenté.Each auxiliary part 4 is positioned in the open position before insertion of an electric wire 2, the orifice 71B is then released, it is held in this position by hooking a notch 46 which it carries on a flange 77 internal to the housing as shown in Figure 6 in the embodiment shown.

L'introduction d'une tige d'outil 5, amovible et à pointe d'extrémité, telle une tige de tournevis de type cruciforme, dans une pièce auxiliaire d'insertion 4 conduit cette tige à venir prendre appui par sa pointe d'extrémité en bordure inférieure du trou 36 à proximité de la paroi de fond 33 de la pièce conductrice qui le comporte.The introduction of a tool rod 5, removable and with an end point, such as a cross-type screwdriver rod, into an auxiliary insertion part 4 leads this rod to come to bear by its end point at the bottom edge of the hole 36 near the bottom wall 33 of the conductive part which comprises it.

L'application d'une force sur la partie de la tige 5 extérieure au bloc, dans le sens longitudinal et vers l'extrémité proche de ce dernier, produit un effet de levier qui débloque la pièce auxiliaire d'insertion 4 et lui permet de se déplacer selon le trajet déterminé par les rainures de guidage.The application of a force on the part of the rod 5 external to the block, in the longitudinal direction and towards the close end of the latter, produces a leverage which unlocks the auxiliary insertion part 4 and allows it to move along the path determined by the guide grooves.

Lorsqu'un fil électrique 2 gainé d'isolant est introduit dans l'orifice 71A en butée par une extrémité contre la paroi de fond 33 de la pièce conductrice 3 -figures 6 et 7-, la pièce auxiliaire d'insertion 4 vient prendre appui sous l'action de la tige 5 sur la gaine 20 du fil au niveau de l'embouchure dénudante évasée de la fente délimitée par les bords 31.When an electric wire 2 sheathed in insulation is introduced into the orifice 71A abutted by one end against the bottom wall 33 of the conductive part 3 -figures 6 and 7-, the auxiliary insertion part 4 comes to bear under the action of the rod 5 on the sheath 20 of the wire at the level of the flared stripped mouth of the slot delimited by the edges 31.

La force exercée transversalement sur la tige 5, qui est multipliée par l'effet de levier, presse la gaine 20 du fil contre les bords coupants de cette embouchure dénudante par l'intermédiaire du .poussoir 40, de manière à couper cette gaine transversalement jusqu'à l'âme 21 de ce filThe force exerted transversely on the rod 5, which is multiplied by the leverage, presses the sheath 20 of the wire against the cutting edges of this stripped mouth by means of the pusher 40, so as to cut this sheath transversely up to 'to the core 21 of this thread

La poursuite du déplacement de la pièce auxiliaire d'insertion 4 sous l'action du levier 5 poursuit la pression du poussoir 40 sur la gaine 20 et conduit l'âme du fil à pénétrer entre les bords 31 de la fente dénudante dans la zone où ces bords sont parallèles et permettent d'assurer l'immobilisation de ce fil par coincement de son âme conductrice 21 en contact avec eux.Continued movement of the auxiliary insertion part 4 under the action of the lever 5 continues the pressure of the pusher 40 on the sheath 20 and leads the core of the wire to penetrate between the edges 31 of the stripping slot in the area where these edges are parallel and make it possible to immobilize this wire by jamming its conductive core 21 in contact with them.

Comme indiqué plus haut l'index 45 permet de vérifier que la pièce auxiliaire d'insertion 4 est venue en fin de course en appui sur la contre-butée 76 de manière à s'assurer que la course d'insertion du fil a été suffisante, ledit index 45 apparaissant ici en ce cas sous la . contre-butée 76 dans l'orifice 71AI comme le montre la figure 7. et s'accrochant sous cette butée qui la retient.As indicated above, the index 45 makes it possible to verify that the auxiliary insertion part 4 has come to the end of the travel by pressing on the counter-stop 76 so as to ensure that the insertion stroke of the wire has been sufficient. , said index 45 appearing here in this case under the. counter-stop 76 in the orifice 71A I as shown in FIG . 7 . and clinging to this stop which holds it.

Le retour de la pièce auxiliaire d'insertion 4 en arrière, dans la position où elle est maintenue par accrochage du cran 45 qu'elle comporte sur le rebord interne 77 du boîtier 7, permet éventuellement l'introduction d'un second fil 2 dans l'orifice 71A, en contact par son extrémité avec la paroi de fond 33 de la pièce conductrice 3, en vue de sa connexion dans la fente dénudante de cette pièce au dessus du fil 2 précédemment raccordé.The return of the auxiliary insertion part 4 backwards, in the position where it is held by hooking the notch 45 which it comprises on the internal rim 77 of the housing 7, optionally allows the introduction of a second wire 2 into the orifice 71A, in contact at its end with the bottom wall 33 of the conductive part 3, with a view to its connection in the stripping slot of this part above the wire 2 previously connected.

La connexion s'effectue de manière identique à celle décrite ci- dessus, la gaine du second fil poussant celle du premier de manière que ce dernier pénètre plus avant entre les bords 31 parallèles de la fente dénudante.The connection is made in an identical manner to that described above, the sheath of the second wire pushing that of the first so that the latter penetrates further between the parallel edges 31 of the stripping slot.
