Description

L'invention concerne les bornes de raccordement électrique pour fils de transport d'énergie, du type à conducteur central multibrins gaîné d'isolant, n'impliquant pas un dénudage des fils.The invention relates to electrical connection terminals for power transmission wires, of the type with a multi-stranded central conductor sheathed in insulation, not involving stripping of the wires.

Il est connu de raccorder des fils de transport d'énergie électrique entre eux au moyen de bornes comportant un corps tubulaire dont une extrémité extérieurement filetée est dotée d'une fente transversale borgne dont le fond forme un berceau agençé pour recevoir des fils électrique superposés, traversants ou non.It is known to connect wires for transporting electrical energy to each other by means of terminals comprising a tubular body, one externally threaded end of which has a blind transverse slot, the bottom of which forms a cradle arranged to receive superimposed electrical wires, through or not.

Un bouchon creux, doté intérieurement d'un poussoir cylindrique central, vient se visser sur l'extrémité fileté du corps tubulaire.A hollow plug, fitted internally with a central cylindrical pusher, is screwed onto the threaded end of the tubular body.

Le poussoir permet de presser et donc d'électriquement intercon­necter des fils, nus ou dénudés, empilés dans la fente entre le fond du berceau et lui-même.The pusher makes it possible to press and therefore electrically interconnect wires, bare or stripped, stacked in the slot between the bottom of the cradle and itself.

Le raccordement électrique des fils usuels, dont l'âme est couverte d'un isolant formé d'une ou plusieur couches, implique l'enlèvement de ces couches de la zone de fil qui doit venir se loger dans la borne.The electrical connection of the usual wires, the core of which is covered with an insulator formed by one or more layers, involves the removal of these layers from the zone of wire which is to be housed in the terminal.

L'enlèvement des couches isolantes doit être effectué avec soin pour ne pas entraîner une détérioration de l'âme conductrice, notamment lorsque cette âme est composée de brins multiples ; il est peu commode à réaliser lorsque la connexion est à effectuer en dérivation sur un fil que l'on ne veut pas morceler.The removal of the insulating layers must be carried out with care so as not to cause deterioration of the conductive core, in particular when this core is composed of multiple strands; it is inconvenient to carry out when the connection is to be carried out in diversion on a wire which one does not want to break up.

La mise à nu de l'âme d'un fil pour sa connexion dans une borne a en plus l'inconvénient d'augmenter les risques de contact pa inadvertance de ce fil avec un appareillage ou une personne, en particulier en cas de sortie du fil de la borne par suite d'un desserrage intempestif de cette dernière.The exposure of the core of a wire for its connection in a terminal has the further disadvantage of increasing the risk of inadvertent pa contact of this wire with an appliance or a person, in particular in the event of removal from the terminal wire as a result of untimely loosening of the terminal.

La présente invention propose donc une borne de raccordement électrique, pour fils de transport d'énergie constitués chacun d'un conducteur multibrins sous isolant. Cette borne comporte un corps rigide doté d'au moins une extrémité tubulaire, filetée ou taraudée, traversée transversalement et au moins partiellement par une ouverture de passage de fil, cette ouverture a une forme allongée parallèle à l'axe longitudinal de ladite extrémité tubulaire et une largeur correspondant au diamètre maximal d'un fil à raccorder. La borne comporte aussi un bouchon portant un poussoir central, ce bouchon se visse en bout de ladite extrémité tubulaire qu'il vient alors fermer ; le poussoir central s'enfonce dans l'extrémité tubulaire au fur et à mesure du vissage.The present invention therefore proposes an electrical connection terminal, for energy transport wires each consisting of a multi-strand conductor under insulation. This terminal comprises a rigid body provided with at least one tubular end, threaded or tapped, crossed transversely and at least partially by a wire passage opening, this opening has a shape elongated parallel to the longitudinal axis of said tubular end and a width corresponding to the maximum diameter of a wire to be connected. The terminal also includes a plug carrying a central pusher, this plug is screwed at the end of said tubular end which it then closes; the central pusher sinks into the tubular end as it is screwed.

Selon une caractéristique de l'invention la borne comporte également au moins une broche conductrice à pointes d'extrémité perforantes respectivement en saillie hors d'une paroi commune à travers les fonds des ouvertures de passage de fil de deux extrémités tubulaires pour permettre l'interconnexion par cette broche des fils respectivement immobilisé chacun contre la paroi de fond commune dans une extrémité tubulaire où pénètre le fil considéré et où ce fil est immobilisés par un bouchon dont le poussoir central vient, en fin de vissage, au voisinage d'une pointe perforante avec lequel ce poussoir est aligné, ledit poussoir central assurant l'enfoncement du fil sur ladite pointe perforante par pression latérale et jusqu'à pénétration de cette pointe perforante en contact avec les brins du conducteur central du fil, après perforation de l'isolant.According to a characteristic of the invention, the terminal also comprises at least one conductive pin with perforating end points respectively projecting from a common wall through the bottoms of the wire passage openings of two tubular ends to allow interconnection. by this wire pin respectively immobilized each against the common bottom wall in a tubular end where the wire in question enters and where this wire is immobilized by a plug whose central pusher comes, at the end of screwing, in the vicinity of a piercing point with which this pusher is aligned, said central pusher ensuring the insertion of the wire on said perforating tip by lateral pressure and until penetration of this perforating tip in contact with the strands of the central conductor of the wire, after perforation of the insulation.

L'invention, ses caractéristiques et ses avantages sont précisés dans la description qui suit en liaison avec les figures répertoriées ci-dessous.

  • La figure 1 présente un exemple de borne de raccordement électrique, selon l'invention, montée sur des fils électriques qu'elle interconnecte.
  • La figure 2 présente une vue éclatée de la borne de raccordement de la figure 1.
  • Les figures 3 et 4 présentent deux coupes longitudinales axiales à angle droit respectivement selon III-III et IV-IV de la borne de raccordement selon l'invention.
  • La figure 5 présente une coupe transversale selon V-V.
The invention, its characteristics and its advantages are explained in the following description in conjunction with the figures listed below.
  • FIG. 1 shows an example of an electrical connection terminal, according to the invention, mounted on electrical wires which it interconnects.
  • Figure 2 shows an exploded view of the connection terminal in Figure 1.
  • Figures 3 and 4 show two axial longitudinal sections at right angles respectively along III-III and IV-IV of the connection terminal according to the invention.
  • Figure 5 shows a cross section along VV.

La borne de raccordement présentée figure 1 est destinée à interconnecter deux fils de transport d'énergie électrique 1, de type à conducteur multibrin 2 sous isolant 3, soit en bout, soit en dérivation, avec ou sans coupure. Elle comporte un corps rigide 4, éventuellement réalisé en métal mais préférablement moulé en matériau isolant, tel un polyamide. Ce corps de borne 4 comporte au moins deux extrémités tubulaires filetées ou taraudées, ici alignées dans l'axe du corps qui est lui-même d'allure tubulaire. Il est également possible de prévoir des extrémités tubulaires obliquement disposées l'une par rapport à l'autre ou parallèlement montées sur un même support. Dans l'exemple proposé, le corps de borne 4 comporte une surépaisseur annulaire 5 dans sa zone centrale, cette surépaisseur permet l'immobilisation du corps dans un trou complémentaire d'une paroi support non figurée, par coincement de cette paroi ente la surépaisseur et un écrou, non figuré, vissé sur le filetage de l'une des extrémités tubulaires.The connection terminal presented in FIG. 1 is intended to interconnect two electrical energy transport wires 1, of the multi-strand conductor type 2 under insulator 3, either at the end, either bypass, with or without interruption. It comprises a rigid body 4, possibly made of metal but preferably molded from an insulating material, such as a polyamide. This terminal body 4 has at least two threaded or tapped tubular ends, here aligned in the axis of the body which is itself tubular in appearance. It is also possible to provide tubular ends obliquely disposed relative to one another or parallel mounted on the same support. In the example proposed, the terminal body 4 has an annular allowance 5 in its central zone, this allowance allows the immobilization of the body in a complementary hole of a support wall which is not shown, by wedging this wall between the allowance and a nut, not shown, screwed onto the thread of one of the tubular ends.

Un bouchon 6 vient se visser en bout de chaque extrémité tubulaire du corps 4. Les bouchons 6 sont destinés à venir emprisoner chacun un fil dans le corps de borne 4 dont les extrémités tubulaires sont dotées chacune d'une ouverture de passage de fil 7 de forme allongée, orientée dans l'axe longitudinal de l'extrémité tubulaire soit ici selon l'axe du corps tubulaire 4.A plug 6 is screwed at the end of each tubular end of the body 4. The plugs 6 are intended to each trap a wire in the terminal body 4, the tubular ends of which are each provided with a wire passage opening 7 of elongated shape, oriented in the longitudinal axis of the tubular end, in this case along the axis of the tubular body 4.

Les ouvertures de passage de fil 7 des extrémités tubulaires sont ici séparées par une paroi de fond commune 8 au travers de laquelle est logée une broche 9 au moins partiellement conductrice qui fait saillie par une pointe de perforation de fils dans chaque ouverture de passage et qui est par exemple fixée par emmanchement à force ou par surmoulage.The wire passage openings 7 of the tubular ends are here separated by a common bottom wall 8 through which is housed an at least partially conductive pin 9 which projects by a wire perforation point in each passage opening and which is for example fixed by force fitting or by overmolding.

Dans le cas d'extrémité tubulaires non alignées selon un même axe longitudinal, la broche 9, éventuellement multibranche, est coudée et saille hors d'une paroi commune, à travers le fond de l'ouverture de passage de fil de chacune des extrémités tubulaires concernées, de telles dispositions aisées à concevoir n'étant pas représentées ici.In the case of tubular ends not aligned along the same longitudinal axis, the pin 9, possibly multi-branch, is bent and protrudes out of a common wall, through the bottom of the wire passage opening of each of the tubular ends concerned, such arrangements which are easy to conceive are not shown here.

Les ouvertures de passage de fil qui s'ouvrent dans la paroi latérale des extrémités tubulaires sont éventuellement borgnes, dans la réalisation proposée elles sont diamétrales et traversent de part en part les extrémités tubulaires au bout desquelles de plus elles s'ouvrent, en délimitant chacune une fente permettant l'insertion d'un fil traversant, soit transversalement par l'extrémité ouverte de la fente, soit radialement sur la hauteur de la fente.The wire passage openings which open in the side wall of the tubular ends are possibly blind, in the proposed embodiment they are diametrical and pass right through the tubular ends at the end of which the more they open, each delimiting a slot allowing the insertion of a through wire, either transversely through the open end of the slot, or radially over the height of the slot.

La largeur de chaque ouverture de passage et par conséquent ici de chaque fente, est fonction du diamètre maximal du fil à connecter que cette fente encourt à immobiliser.The width of each passage opening and therefore here of each slot, is a function of the maximum diameter of the wire to be connected that this slot incurs to immobilize.

Dans la réalisation proposée et notamment pour des raisons d'économie de matière, les extrémités tubulaires sont creuses et le diamètre maximal admissible pour un fil 1 dans une fente est fixé par les deux encoches identiques 10- ici référencées au niveau de leurs deux bords sur la figure 4- qui bornent cette fente. Ces encoches 10 sont ménagées symétriquement par rapport à un plan longitudinal médian du corps et de manière diamétralement opposée au travers de la paroi de chaque extrémité tubulaire.In the proposed embodiment and in particular for reasons of economy of material, the tubular ends are hollow and the maximum admissible diameter for a wire 1 in a slot is fixed by the two identical notches 10- here referenced at their two edges on Figure 4- which limit this slot. These notches 10 are formed symmetrically with respect to a median longitudinal plane of the body and diametrically opposite through the wall of each tubular end.

La broche 9 est ici rectiligne, axialement disposée et immobilisée dans le corps 4 et la hauteur de saillie d'une pointe perforante de broche 9, au dessus de la paroi de fond commune 8 dans l'une des ouvertures de passage de fil- soit ici dans l'une des fentes- est choisie pour assurer un passage radial de la pointe à travers l'isolant 3 d'un fil 1 et entre les brins du conducteur central 2 de ce fil. La hauteur de cette saillie est préférablement limitée de manière à éviter une traversée diamétrale complète du fil 1 par la pointe perforante et une sortie de cete dernière hors de ce fil après traversée.The pin 9 is here rectilinear, axially disposed and immobilized in the body 4 and the height of projection of a pin piercing tip 9, above the common bottom wall 8 in one of the wire passage openings - either here in one of the slots- is chosen to ensure a radial passage of the tip through the insulator 3 of a wire 1 and between the strands of the central conductor 2 of this wire. The height of this projection is preferably limited so as to avoid a complete diametrical crossing of the wire 1 by the piercing tip and an exit of the latter out of this wire after crossing.

La mise en place d'un bouchon 6 sur une extrémité tubulaire s'effectue par vissage, le bouchon étant soit fileté extérieurement pour s'insérer dans le taraudage d'une extrémité tubulaire selon une solution non représentée ici, soit taraudé intérieurement pour venir se visser sur le filetage 11 réalisé extérieurement sur chaque extrémité tubulaire comme montré sur les figures 1 à 4.The establishment of a plug 6 on a tubular end is carried out by screwing, the plug being either externally threaded to fit into the thread of a tubular end according to a solution not shown here, or internally threaded to come screw on the thread 11 made externally on each tubular end as shown in Figures 1 to 4.

Chaque bouchon 6 comporte un poussoir central 12 pénétrant dans l'extrémité tubulaire où il se visse de manière à s'approcher de la pointe de perforation logée dans cette extrémité, au fur et à mesure de son vissage et jusqu'à une distance correspondant à l'épaisseur de l'isolant 3 du fil 1 dont la connexion est prévue dans cette extrémité tubulaire.Each plug 6 comprises a central pusher 12 penetrating into the tubular end where it is screwed so as to approach the perforation point housed in this end, as and when it is screwed and up to a distance corresponding to the thickness of the insulation 3 of the wire 1 whose connection is provided in this tubular end.

Le poussoir central 12 est ici creux et composé d'une base cylindrique se terminant par une partie tronconique destinée à venir appuyer latéralement, par une portée annulaire de diamètre plus faible que le cylindre de base, sur un fil en position de raccordement.The central pusher 12 is here hollow and composed of a cylindrical base ending in a frustoconical part intended to come to bear laterally, by an annular bearing of diameter smaller than the base cylinder, on a wire in the connection position.

Le raccordement d'un fil 1, traversant, s'effectue par position­nement du fil au travers de la fente d'une extrémité tubulaire après que le bouchon 6 correspondant ait été dévissé, soit partielle­ment pour permettre l'introduction du fil entre la pointe de perforation et le bouchon, si la course de ce dernier le permet, soit totalement le fil venant s'insérer en traversée dans la fente une fois le bouchon ôté.The connection of a wire 1, passing through, is carried out by positioning the wire through the slot of a tubular end after the corresponding plug 6 has been unscrewed, or partially to allow the introduction of the wire between the tip of perforation and the plug, if the stroke of the latter allows it, or completely the wire coming to be inserted through the slot in the slot once the plug is removed.

Cette dernière possibilité permet le montage de la borne sans dénudage ni morcellement du fil, ce dernier étant éventuellement installé à demeure.This last possibility allows the mounting of the terminal without stripping or splitting of the wire, the latter possibly being permanently installed.

Le vissage du bouchon 6 sur l'extrémité tubulaire, après remise en place éventuelle de ce bouchon, pousse le fil contre la pointe de perforation de la broche ; cette dernière s'enfonce dans le fil à travers l'isolant et vient en contact avec les brins du conducteur central 3 assurant ainsi une continuité électrique.The screwing of the plug 6 on the tubular end, after possible replacement of this plug, pushes the wire against the perforation point of the spindle; the latter is inserted into the wire through the insulator and comes into contact with the strands of the central conductor 3 thus ensuring electrical continuity.

En supplément, dans la réalisation proposée, les extrémités tubulaires sont creuses et on prévoit deux nervures longitudinales 13 de guidage et de coincement de fil, par extrémité tubulaire. Les deux nervures 13 d'une extrémité tubulaire sont coplanaires et disposées symétriquement par rapport au plan médian, déjà évoqué plus haut en liaison avec les encoches 10, auxquelles ces nervures sont parallèles. Le guidage d'un fil à raccorder est assuré par l'obliquité des nervures qui tendent dans une première partie à conduire ce fil vers le centre de l'élément tubulaire au-dessus de la pointe. Dans une seconde partie, les nervures 13 d'une extrémité tubulaire sont parallèles entre elles et entourent la pointe de perforation qui contient cette extrémité tubulaire, elles sont alors séparées par une distance correspondant au diamètre du fil à raccorder de manière à centrer ce fil sur la pointe, lors du raccordement, et à participer à son immobilisation.In addition, in the proposed embodiment, the tubular ends are hollow and two longitudinal ribs 13 are provided for guiding and wedging the wire, per tubular end. The two ribs 13 of a tubular end are coplanar and arranged symmetrically with respect to the median plane, already mentioned above in connection with the notches 10, to which these ribs are parallel. The guiding of a wire to be connected is ensured by the obliquity of the ribs which tend in a first part to conduct this wire towards the center of the tubular element above the tip. In a second part, the ribs 13 of a tubular end are parallel to each other and surround the perforation point which contains this tubular end, they are then separated by a distance corresponding to the diameter of the wire to be connected so as to center this wire on the tip, during connection, and to participate in its immobilization.

La borne de raccordement selon l'invention permet également de raccorder à un fil, dont le diamètre est défini par la largeur de fente d'une extrémité tubulaire, un autre fil de diamètre inférieur au moyen d'un fourreau 14 venant s'insérer dans une extrémité tubulaire autour d'une pointe de perforation de broche 9, entre la paroi de fond qui porte cette broche 9 et le bouchon 6 qui ferme l'extrémité tubulaire considérée.The connection terminal according to the invention also makes it possible to connect to a wire, the diameter of which is defined by the slot width of a tubular end, another wire of smaller diameter by means of a sheath 14 coming to be inserted in a tubular end around a pin perforation point 9, between the bottom wall which carries this pin 9 and the plug 6 which closes the tubular end in question.

Le fourreau 14 a des formes externes complémentaires des formes des éléments évoquées ci-dessus entre lesquels ils vient se loger. Ce fourreau 14 comporte ici un corps 15 d'allure grossièrement cylindrique destinée à s'insérer à l'intérieur une extrémité tubulaire à travers le bout ouvert de cette dernière. Le corps 15 est latérale­ment doté de deux rainures longitudinales 16 complémentaires des nervures 13 d'une extrémité tubulaire -figure 2, 4 et 5-. Ces rainures permettent d'immobiliser en rotation le corps 15 dans une extrémité tubulaire et le guident en translation.The sheath 14 has external shapes complementary to the shapes of the elements mentioned above between which they are housed. This sheath 14 here comprises a body 15 of roughly cylindrical appearance intended to be inserted inside a tubular end through the open end of the latter. The body 15 is laterally provided with two longitudinal grooves 16 complementary to the ribs 13 of a tubular end -figure 2, 4 and 5-. These grooves make it possible to immobilize the body 15 in rotation in a tubular end and guide it in translation.

Dans l'exemple de réalisation proposé, le corps 15 est réalisé en matériau isolant moulé, il est axialement muni d'un orifice circulaire 17 destiné à permettre la pénétration d'une pointe perforan­te de broche 3 dans un conduit 18 transversalement ménagé en fond de corps 15, près de cet orifice 17.In the proposed embodiment, the body 15 is made of molded insulating material, it is axially provided with a circular orifice 17 intended to allow the penetration of a pin piercing tip 3 into a conduit 18 transversely formed at the bottom of body 15, near this orifice 17.

Le conduit transversal 18, éventuellement traversant mais ici présenté borgne, est destiné à assurer le maintien d'un fil ; il est ménagé de manière à s'ouvrir face à à une encoche 10 entre les bords de cette dernière ce qui permet le passage du fil vers ce conduit.The transverse conduit 18, possibly through but here shown blind, is intended to ensure the maintenance of a wire; it is arranged so as to open facing a notch 10 between the edges of the latter which allows the passage of the wire to this conduit.

Il est possible de faire passer un fil en traversée dans un conduit si celui-ci débouche au niveau des deux encoches 10 qui l'entourent.It is possible to pass a wire through a conduit if it leads to the two notches 10 which surround it.

L'extrémité du corps 15 qui est à l'opposé de l'orifice circulai­re 17 est ici prolongée par un élément annulaire extérieurement surplombant 19, destiné à venir s'insérer entre un bouchon 6 et l'extrémité tubulaire où ce bouchon se visse de manière à limiter l'enfoncement du fourreau 14 dans l'extrémité tubulaire et à immobili­ ser ce fourreau en translation, lorsque le bouchon 6 est totalement vissé.The end of the body 15 which is opposite the circular orifice 17 is here extended by an externally overhanging annular element 19, intended to be inserted between a plug 6 and the tubular end where this plug is screwed so as to limit the insertion of the sheath 14 into the tubular end and to immobili ser this sheath in translation, when the plug 6 is fully screwed.

L'enfoncement maximal du fourreau 14 dans une extrémité tubulaire est préférablement choisi de manière que la pointe de perforation logée dans cette extrémité tubulaire saille dans la cavité transversa­le 18 du fourreau sur une hauteur lui permettant de traverser l'isolant 3 d'un côté du fil et les brins du conducteur central 2 sans ressortir de l'autre côté du fil.The maximum insertion of the sleeve 14 into a tubular end is preferably chosen so that the perforation point housed in this tubular end projects into the transverse cavity 18 of the sleeve over a height allowing it to pass through the insulation 3 on one side of the wire and the strands of the central conductor 2 without emerging from the other side of the wire.

Dans la forme de réalistion présentée, le corps 15 comporte aussi un agencement permettant l'accrochage du fourreau 14 à un bouchon 6 au niveau du poussoir central 12 de ce bouchon.In the embodiment shown, the body 15 also includes an arrangement allowing the sheath 14 to be hooked to a plug 6 at the level of the central pusher 12 of this plug.

Cet agencement d'accrochage comprend une cavité axiale 20 ménagée dans le corps 15 de manière à s'ouvrir au centre de l'élément annulaire 19 et à pouvoir recevoir le poussoir central 12, elle présente à cet effet une structure dont le profil est complémentaire de celui du poussoir ce qui lui permet de transmettre au corps 15 la pression qu'exerce ce poussoir lors du vissage du bouchon.This attachment arrangement comprises an axial cavity 20 formed in the body 15 so as to open at the center of the annular element 19 and to be able to receive the central pusher 12, it has for this purpose a structure whose profile is complementary that of the pusher which allows it to transmit to the body 15 the pressure exerted by this pusher when the cap is screwed on.

Un téton central 21 ménagé au fond de la cavité axiale 20 permet d'assujettir en translation le fourreau au bouchon 6 lors du retrait de ce dernier. Dans la réalistion présentée, le téton central 21 vient s'encliqueter dans un logement complémentaire 22 s'ouvrant en bout de poussoir central 12 de bouchon.A central stud 21 formed at the bottom of the axial cavity 20 makes it possible to subject the sheath in translation to the plug 6 when the latter is withdrawn. In the embodiment shown, the central stud 21 snaps into a complementary housing 22 opening at the end of the central pusher 12 of the plug.

Le raccordement d'un fil 1 de diamètre inférieur à un autre fil 1 à l'aide d'une borne de raccordement selon l'invention, s'effec­tue préférablement en connectant en premier le fil de plus gros diamètre, du côté par où la broche est emmanchée dans la paroi de fond commune 8 dans le cas d'une broche 9 enfonçée à force. Le fil de plus faible diamètre est alors introduit dans le conduit transversal 18 d'un fourreau 14 assujetti à un bouchon 6. Le vissage du bouchon 6 sur une extrémité tubulaire de borne fait descendre le fourreau, dans cette extrémité tubulaire, autour de la pointe perforante logée dans cette extrémité, il entraîne la pénétration de cette pointe transversalement à l'intérieur du fil où elle vient en contact avec les brins du conducteur central pour assurer la continuité électrique entre fils.The connection of a wire 1 of smaller diameter to another wire 1 using a connection terminal according to the invention is preferably carried out by first connecting the wire of larger diameter, on the side where the spindle is fitted into the common bottom wall 8 in the case of a spindle 9 forced into it. The wire of smaller diameter is then introduced into the transverse conduit 18 of a sheath 14 subject to a plug 6. The screwing of the plug 6 on a tubular terminal end lowers the sheath, in this tubular end, around the tip perforating housed in this end, it causes this point to penetrate transversely inside the wire where it comes into contact with the strands of the central conductor to ensure electrical continuity between wires.

Il est bien entendu envisageable de connecter deux fils de diamètres inférieurs au diamètre maximal prévu avec la borne de raccordement considéré en mettant en oeuvre deux fourreaux prévus pour des fils correspondants aux deux fils considérés.It is of course conceivable to connect two wires of diameters smaller than the maximum diameter provided with the connection terminal considered by implementing two sleeves provided for wires corresponding to the two wires considered.

Dans la forme de réalisation proposée, il est prévu d'éviter la pénétration d'humidité dans les fils d'une part à l'aide d'une surépaisseur annulaire 23 ménagée sur la paroi de fond commune 8 autour de la broche 9 de part et d'autre de cette paroi de fond. Cette surépaisseur annulaire vient en effet se plaquer sur l'isolant 3 d'un fil autour de la broche, lorsque ce fil enfoncé en fond de fente par un bouchon 6.In the proposed embodiment, provision is made to avoid the penetration of moisture into the wires on the one hand using an annular allowance 23 formed on the common bottom wall 8 around the pin 9 on the other hand and on the other side of this bottom wall. This annular allowance is in fact pressed against the insulator 3 of a wire around the spindle, when this wire pressed into the bottom of the slot by a plug 6.

Lorsqu'un fourreau 14 est mis en oeuvre, il est prévu de ceinturer la broche 9 par un premier joint 24 d'étanchéité venant se placer, entre paroi de fond 8 et corps 15 de fourreau, dans une rainure circulaire extérieure de positionnement 25 alors prévue pour ce joint sur la broche.When a sleeve 14 is used, provision is made to surround the spindle 9 with a first seal 24 which is placed, between the bottom wall 8 and body 15 of the sleeve, in an external circular positioning groove 25. provided for this seal on the spindle.

Un second joint 26 d'étanchéité est également prévu à proximité de l'embouchure du conduit transversal 18, dans une rainure circulaire intérieure 27 du corps 15, de manière à venir ceinturer le fil introduit dans ce conduit.A second seal 26 is also provided near the mouth of the transverse conduit 18, in an inner circular groove 27 of the body 15, so as to come and surround the wire introduced into this conduit.

Il est bien entendu envisageable de disposer un joint à chaque embouchure de conduit transversal 18, si celui-ci s'ouvre des deux côtés du corps 15 pour permettre un passage de fil en traversée.It is of course conceivable to have a seal at each mouth of the transverse conduit 18, if the latter opens on both sides of the body 15 to allow a passage of wire through.

Il est également prévu la possibilité de raccorder plus de deux fils ensemble à l'aide d'une borne dont le corps comporte autant d'extrémité tubulaires que de fils à raccorder chaque extrémité tubulaire comportant une pointe perforante de broche électriquement reliée aux pointes perforantes des autres extrémités tubulaires.It is also provided for the possibility of connecting more than two wires together using a terminal whose body has as many tubular ends as there are wires to be connected each tubular end comprising a pin piercing tip electrically connected to the piercing tips of other tubular ends.
