Description

La présente invention porte sur un module de connexion/déconnexion de paires de conducteurs électriques isolés. De tels modules sont en particulier destinés à la constitution d'ensembles de raccordement et de brassage des connexions entre paires de conducteurs.The present invention relates to a connection / disconnection module of isolated electrical conductor pairs. Such modules are particularly intended for the constitution of connection assemblies and mixing connections between pairs of conductors.

On connaît par le document EP-A-0 248 743 un dispositif modulaire de connexion de paires de conducteurs isolés. Ce dispositif comporte un support isolant, deux empilements gigognes de contacts tubulaires dans le support, des moyens de guidage permettant un déplacement relatif axial, mais non angulaire entre chaque contact et le support, et une vis d'actionnement assurant cette translation relative entre deux des contacts côte à côte et le support.Document EP-A-0 248 743 discloses a modular device for connecting insulated conductor pairs. This device comprises an insulating support, two nesting stacks of tubular contacts in the support, guide means allowing axial relative displacement, but not angular between each contact and the support, and an actuating screw ensuring that relative translation between two of the contacts side by side and the support.

Dans ce dispositif connu, les contacts sont tous identiques. Chacun d'eux a ses deux extrémités autodénudantes, pour le raccordement d'un conducteur dans l'une des extrémités autodénudantes, et a l'une de ses extrémités enfichable dans l'autre extrémité d'un autre contact dans chaque empilement.In this known device, the contacts are all identical. Each of them has its two insulation displacement ends, for the connection of a conductor in one of the insulation displacement ends, and has one end plugged into the other end of another contact in each stack.

Le support comporte des douilles elles-mêmes enfichables, qui sont retenues sur une embase métallique et reliée à la masse et qui retiennent intérieurement entre elles les deux empilements de contacts. Des passages sont prévus dans les douilles, en étant en vis à vis des extrémités autodénudantes des contacts. Ils reçoivent les conducteurs électriques, qui sont raccordés dans les extrémités autodénudantes par le déplacement relatif simultané entre les contacts côte à côte et l'une des douilles, assuré par actionnement de la vis s'ancrant alors dans l'embase.The support comprises plugs themselves pluggable, which are retained on a metal base and connected to the ground and which hold internally between them the two stacks of contacts. Passages are provided in the sockets, being opposite the self-cutting ends of the contacts. They receive the electrical conductors, which are connected in the insulation displacement ends by the simultaneous relative movement between the side-by-side contacts and one of the sockets, provided by actuation of the screw then anchoring in the base.

Le débrochage des contacts empilés peut également être réalisé par actionnement de la vis et son retrait de l'embase, pour le désenfichage résultant des contacts précédemment empilés.The removal of the stacked contacts can also be achieved by actuating the screw and removing it from the base, for unplugging resulting from the previously stacked contacts.

Ce dispositif connu peut aussi comporter un parasurtenseur de protection des équipements raccordés aux conducteurs électriques. Ce parasurtenseur est monté amovible sur une douille intermédiaire dans l'empilage des douilles.

Les modules de connexion/déconnexion des figures 1 et 2 sont décrits simultanément en précisant leurs différences essentielles en regard de ces figures.The connection / disconnection modules of FIGS. 1 and 2 are described simultaneously, specifying their essential differences with respect to these figures.

Chacun des modules comporte deux fiches de connexion 1 et 2 et un support isolant 3, sur lequel les deux fiches sont montées en vis à vis et viennent s'enficher l'une dans l'autre et dans le support.Each of the modules comprises two connection plugs 1 and 2 and an insulating support 3, on which the two plugs are mounted opposite and are plugged into one another and into the support.

Ces fiches 1 et 2 sont affectées chacune au raccordement d'une paire de conducteurs électriques isolés. A cet effet, la fiche 1 comporte deux premiers contacts tubulaires identiques l'un à l'autre, non visibles mais désignés ci-après par la référence 11, et un premier poussoir 12 monté mobile sur une première extrémité de ces contacts. Le poussoir 12 assure le maintien côte à côte de ces contacts et assure le raccordement d'une première paire de conducteurs dans la première extrémité des contacts. Il comporte deux passages 13, prévus transversalement aux contacts et en vis à vis de leur première extrémité, pour la réception des conducteurs. La deuxième fiche 2 comporte de manière analogue deux deuxièmes contacts identiques l'un à l'autre mais pas aux premiers, qui sont non visibles dans ces figures, mais désignés ci-après par la référence 21, et un deuxième poussoir 22 mobile sur la première extrémité de ces contacts. Ce deuxième poussoir assure le maintien côte à côte des deux deuxièmes contacts. Il présente deux passages 23 transversaux aux deuxièmes contacts et situés en vis à vis de leur première extrémité, pour le raccordement d'une deuxième paire de conducteurs insérés dans ces passages aux deuxièmes contacts.These pins 1 and 2 are each assigned to the connection of a pair of insulated electrical conductors. For this purpose, the plug 1 comprises two first tubular contacts identical to each other, not visible but designated hereinafter by the reference 11, and a first pusher 12 mounted to move on a first end of these contacts. The pusher 12 maintains these contacts side by side and ensures the connection of a first pair of conductors in the first end of the contacts. It comprises two passages 13, provided transversely to the contacts and opposite their first end, for receiving conductors. The second plug 2 similarly comprises two second identical contacts to each other but not to the first ones, which are not visible in these figures, but designated hereinafter by the reference 21, and a second pusher 22 movable on the first end of these contacts. This second pusher maintains the two second contacts side by side. It has two passages 23 transverse to the second contacts and located opposite their first end, for connecting a second pair of conductors inserted in these passages to the second contacts.

Les deuxièmes extrémités des deux premiers et deuxièmes contacts sont les extrémités d'enfichage des fiches l'une dans l'autre.The second ends of the first two and second contacts are the plug-in ends of the plugs one inside the other.

Le support 3 définit une base 30 de forme globale rectangulaire et présente un plot transversal de connexion saillant sur une face de connexion 31 de la base. Ce plot est désigné différemment par la référence 5 dans la figure 1 et la référence 6 dans la figure 6. Il est de forme globale parallélépipédique, le plot 6 étant sensiblement plus saillant que le plot 5. Il est prévu sur l'une des parties terminales de la base. En variante ce plot peut être non terminal, en étant médian ou non sur la base.The support 3 defines a base 30 of rectangular overall shape and has a transverse connecting stud protruding on a connection face 31 of the base. This pad is designated differently by the reference numeral 5 in FIG. 1 and the reference numeral 6 in FIG. 6. It is of parallelepipedal overall shape, the stud 6 being substantially more protruding than stud 5. It is provided on one of the parts terminals of the base. As a variant, this pad may be non-terminal, while being median or not on the base.

Les plots 5 et 6 ont pour fonction commune d'assurer l'enfichage des fiches 1 et 2. Ils comportent l'un comme l'autre à cet effet, deux premiers logements intérieurs identiques l'un à l'autre, non visibles dans ces figures 1 et 2, mais désignés ci-après par la référence 61. Ces deux premiers logements, dans l'un et l'autre des plots, sont prévus côte à côte, sont parallèles à la base 30 et sont ouverts de part et d'autre du plot, sur deux faces opposées d'enfichage des fiches 1 et 2 dans le plot.Plots 5 and 6 have the common function of inserting the plugs 1 and 2. They include the one and the other for this purpose, two first inner housings identical to one another, not visible in 1 and 2, but designated hereinafter by the reference 61. These first two housings, in one and the other of the pads, are provided side by side, are parallel to the base 30 and are open on both sides. else of the stud, on two opposite faces of plugs 1 and 2 in the stud.

Le plot 6 permet d'assurer en outre une fonction supplémentaire de protection d'équipements raccordés aux paires de conducteurs raccordées par le module de connexion/déconnexion de la figure 2. Il comporte à cet effet trois logements supplémentaires, qui sont latéraux pour deux d'entre eux 63 et débouchent d'une part dans les deux premiers logements, et d'autre part sur la face du plot 6 opposée à la base, et qui est médian pour le troisième 64 de ces logements supplémentaires et débouche d'une part à travers la base 30 et d'autre part également sur la face du plot 6 opposée à la base. Deux troisièmes contacts 65 sont montés dans les deux logements latéraux 63 et un contact dit de masse 66 dans le logement médian 64.The stud 6 also makes it possible to provide an additional protection function for equipment connected to the pairs of conductors connected by the connection / disconnection module of FIG. 2. It comprises for this purpose three additional housings, which are lateral for two d 'between them 63 and open on the one hand in the first two homes, and on the other hand on the face of the stud 6 opposite the base, and which is median for the third 64 of these additional housing and opens on the one hand through the base 30 and also on the face of the stud 6 opposite the base. Two third contacts 65 are mounted in the two lateral housings 63 and a so-called ground contact 66 in the median housing 64.

Le module de connexion/déconnexion de la figure 2 comporte en correspondance avec ce plot 6 un module parasurtenseur tripolaire 7, qui s'enfiche sur le plot 6 et se connecte ainsi aux deux troisièmes contacts 65 et au contact de masse 66 dans celui-ci.The connection / disconnection module of FIG. 2 comprises, in correspondence with this pad 6, a three-pole surge protection module 7, which plugs into the pad 6 and thus connects to the two third contacts 65 and to the ground contact 66 in the latter. .

La description plus détaillée des modules de ces figures 1 et 2 est faite en se référant plus particulièrement aux figures 3 et 4 et/ou 5 et 6 relatives au module de connexion/déconnexion de la figure 2, sachant que mises à part les dispositions spécifiques à la fonction supplémentaire de ce dernier, les modules de connexion/déconnexion des figures 1 et 2 sont par ailleurs identiques l'un à l'autre.The more detailed description of the modules of these FIGS. 1 and 2 is made with particular reference to FIGS. 3 and 4 and / or 5 and 6 relating to the connection / disconnection module of FIG. 2, except that the specific provisions to the additional function of the latter, the connection / disconnection modules of Figures 1 and 2 are otherwise identical to each other.

Les deux premiers contacts 11 de la première fiche 1 sont tubulaires, tandis que les deuxièmes contacts 21 de la deuxième fiche 2 sont plats.The first two contacts 11 of the first plug 1 are tubular, while the second contacts 21 of the second plug 2 are flat.

La première extrémité des premiers contacts présente deux fentes opposées autodénudantes 14. La deuxième extrémité opposée présente également deux fentes opposées 15, non autodénudantes, mais d'élasticité de cette extrémité d'enfichage.The first end of the first contacts has two opposed insulation displacement slots 14. The opposite second end also has two opposite slots 15, not self-shrinking, but of elasticity of this plugging end.

La première extrémité des deuxièmes contacts présente une fente axiale autodénudante 24. La deuxième extrémité présente une autre fente axiale 25, non autodénudante, mais d'élasticité de cette deuxième extrémité. Sa largeur est sensiblement égale au diamètre intérieur de la deuxième extrémité de chaque premier contact, pour leur enfichage élastique.The first end of the second contacts has an insulation displacement axial slot 24. The second end has another axial slot 25, non-insulation displacement, but elasticity of the second end. Its width is substantially equal to the inside diameter of the second end of each first contact, for their elastic plugging.

Le premier poussoir 12 définit un corps comportant deux tubulures identiques 17, qui sont saillantes côte à côte d'un côté dit avant du poussoir et reçoivent les premières extrémités des premiers contacts. Chacune de ces tubulures présente une fente 17A, qui se superpose sur l'une des fentes 15 de l'un des contacts 11 et vient au-dessus de la fente 25 de l'un des contacts 21 quand les fiches 1 et 2 sont enfichées dans le plot 6 et l'une dans l'autre. Les passages 13 dans ce premier poussoir sont définis par deux autres tubulures, qui sont saillantes côte à côte sur une face supérieure de ce poussoir et sont désignées par ces mêmes références 13, pour recevoir les deux conducteurs à raccorder simultanément aux deux premiers contacts dans le premier poussoir 12. Les tubulures 13 sont transversales aux tubulures 17 et débouchent dans ces dernières, respectivement. Elles ont une seule extrémité ouverte, avant ou supérieure selon la tubulure, leur autre extrémité étant fermée.The first pusher 12 defines a body having two identical pipes 17, which are projecting side by side on a so-called front side of the pusher and receive the first ends of the first contacts. Each of these pipes has a slot 17A, which is superimposed on one of the slots 15 of one of the contacts 11 and comes above the slot 25 of one of the contacts 21 when the pins 1 and 2 are plugged in the stud 6 and one in the other. The passages 13 in this first pusher are defined by two other pipes, which are projecting side by side on an upper face of this pusher and are designated by these same references 13, to receive the two conductors to be connected simultaneously to the first two contacts in the first pusher 12. The tubing 13 are transverse to the tubing 17 and open into the latter, respectively. They have only one open end, front or upper depending on the tubing, their other end being closed.

Le deuxième poussoir 22 présente quant à lui deux rainures 27, intérieurement profondes et côte à côte, qui reçoivent les premières extrémités des deuxièmes contacts 21 et débouchent dans deux évidements 28 en face dite avant de ce poussoir. Il comporte aussi les deux passages 23, transversaux aux rainures 27 et débouchant dans celles-ci, pour recevoir les deux conducteurs à raccorder dans la première extrémité autodénudante des contacts 21. Les extrémités avant des rainures 27 et les extrémités supérieures des passages 23 sont seules ouvertes, les extrémités opposées étant fermées.The second pusher 22 has two grooves 27, internally deep and side by side, which receive the first ends of the second contacts 21 and open into two recesses 28 opposite said front of this pusher. It also comprises the two passages 23, transverse to the grooves 27 and opening therein, for receiving the two conductors to be connected in the first self-cutting end of the contacts 21. The front ends of the grooves 27 and the upper ends of the passages 23 are alone open, the opposite ends being closed.

Les premiers logements 61 d'enfichage des fiches 1 et 2 dans le plot 6 et l'une dans l'autre sont de forme cylindrique et de diamètre intérieur juste prévu pour l'enfichage des tubulures 17 dans ceux-ci. Ils ont une première ouverture circulaire 67, de même diamètre qu'eux, d'entrée des tubulures 17. Ils ont une deuxième ouverture adaptée 69, de forme rectangulaire, pour recevoir les deuxièmes extrémités d'enfichage des deuxièmes contacts 21. Ils présentent aussi un rebord périphérique 68 autour de chaque deuxième ouverture, qui est complémentaire de chacun des évidements 28 prévus dans le deuxième poussoir et s'encastre dans l'un de ceux-ci.The first housing 61 for inserting the plugs 1 and 2 in the stud 6 and one in the other are of cylindrical shape and inner diameter just provided for the insertion of the tubes 17 therein. They have a first circular opening 67, of the same diameter as them, of inlet of the tubes 17. They have a second adapted opening 69, of rectangular shape, to receive the second plug-in ends of the second contacts 21. They also have a peripheral flange 68 around each second opening, which is complementary to each of the recesses 28 provided in the second pusher and is embedded in one of these.

Les deux contacts latéraux 65 dans le plot sont des contacts plats et droits. L'extrémité la plus intérieure dans le plot de chacun de ces contacts forme une patte 65A, sur laquelle viennent coulisser la fente 17A de l'une des tubulures 17, les fentes 15 de l'un des contacts 11 et la fente 25 de l'un des contacts 21, quand les fiches 1 et 2 s'enfichent dans le plot et l'une dans l'autre. L'autre extrémité dite supérieure de chacun de ces contacts dans le plot présente une fente axiale 65B de serrage élastique de la patte de ligne correspondante du parasurtenseur s'embrochant dans cette fente.The two lateral contacts 65 in the stud are flat and straight contacts. The innermost end in the stud of each of these contacts forms a tab 65A, on which slide the slot 17A of one of the tubes 17, the slots 15 of one of the contacts 11 and the slot 25 of the one of the contacts 21, when the plugs 1 and 2 are plugged into the stud and one into the other. The other so-called upper end of each of these contacts in the stud has an axial slot 65B of elastic clamping of the corresponding line tab of the surge protector interlocking in this slot.

Le contact de masse 66 dans le plot est également un contact plat, plus long que les contacts 65, mais non droit. Il présente une portion terminale découpée en U, qui est saillante sous la base, et dont la branche terminale forme un ressort frotteur 66A. Ce ressort frotteur terminal 66A est sensiblement parallèle à la base 30 et à relativement faible distance de celle-ci. L'autre extrémité du contact de masse 66 présente une fente axiale 66B, dans laquelle s'embroche la patte de masse du parasurtenseur.The ground contact 66 in the pad is also a flat contact, longer than the contacts 65, but not straight. It has a terminal portion cut in U, which is projecting under the base, and whose end branch forms a friction spring 66A. This terminal friction spring 66A is substantially parallel to the base 30 and at a relatively short distance therefrom. The other end of the ground contact 66 has an axial slot 66B, in which the grounding tab of the surge protector engages.

Le module parasurtenseur embrochable sur le plot, qui a été illustré dans la figure 2, n'est pas représenté dans les autres figures suivantes. On comprend aisément pour autant que ce module présente un évidement dans sa face inférieure, qui est de forme complémentaire du plot et dans lequel les deux pattes de ligne et la patte de masse du parasurtenseur sont saillantes, pour que le module parasurtenseur s'embroche sur le plot avec les pattes de ligne et de masse s'embrochant dans les deux contacts 65 et le contact 66.The plug-in surge protector module on the stud, which has been illustrated in FIG. 2, is not shown in the following other figures. It is easily understood as far as this module has a recess in its lower face, which is of complementary shape of the pad and in which the two line tabs and the ground tab of the surge protector are protruding, so that the surge protector module intermesh on the stud with the lugs of line and ground meshing in the two contacts 65 and the contact 66.

En se référant plus particulièrement aux figures 3, 4 ou 5, on voit que la base 30 sert de coulisse à la fiche de connexion 2. A cet effet, la base 30 comporte une fente axiale 36, relativement étroite dans sa portion située du côté du plot 6 et plus large dans sa portion opposée. Le poussoir 22 comporte en correspondance un pied épaulé 26 pour son montage en coulisseau sur la base. Le pied épaulé s'insère à travers la portion large de la fente 36 et est retenu et guidé le long de la portion étroite de cette fente.Referring more particularly to FIGS. 3, 4 or 5, it can be seen that the base 30 serves as a slide for the connection plug 2. For this purpose, the base 30 has an axial slot 36 which is relatively narrow in its portion on the side. pad 6 and wider in its opposite portion. The pusher 22 comprises in correspondence a stepped foot 26 for its slide assembly on the base. The stepped foot is inserted through the wide portion of the slot 36 and is retained and guided along the narrow portion of this slot.

En outre, ainsi qu'il apparaît en particulier dans les figures 4 et 5, le support 3 est équipé pour son montage amovible sur un rail de maintien et assemblage de modules de connexion/déconnexion identiques côte à côte. Des rebords périphériques sont saillants sous la base. Les rebords longitudinaux 37 tronqués en hauteur par rapport aux rebords transversaux et une patte transversale 38 solidaire du rebord transversal situé sous le plot 6 servent d'appui sur le rail, de part et d'autre de celui-ci. Une patte élastique 39 solidaire de l'autre rebord transversal et opposée à la patte 38 assure la fixation du support 3 et ainsi du module de connexion/déconnexion sur ce rail. Elle est escamotable à l'aide d'un tournevis ou analogue pour le décrochage à souhait du module de connexion/déconnexion. Ce rail est un rail métallique standard, en particulier un rail "DIN 35", sur lequel le frotteur terminal 66A du contact de masse est en appui élastique.In addition, as appears in particular in Figures 4 and 5, the support 3 is equipped for its removable assembly on a holding rail and assembly of connection / disconnection modules identical side by side. Peripheral rims protrude below the base. The longitudinal flanges 37 truncated in height relative to the transverse flanges and a transverse tab 38 secured to the transverse flange located under the stud 6 serve as a support on the rail, on either side thereof. A resilient lug 39 integral with the other transverse flange and opposite the lug 38 ensures the attachment of the support 3 and thus the connection / disconnection module on this rail. It is retractable using a screwdriver or the like for the desired stall of the connection module / disconnection. This rail is a standard metal rail, in particular a rail "DIN 35", on which the end contactor 66A of the mass contact is in elastic support.

Les figures 5 et 6 montrent le module de connexion/déconnexion dans une position initiale des fiches 1 et 2 sur la base 30 du support 3, les poussoirs 12 et 22 étant eux-mêmes dans une position initiale sur leurs contacts respectifs 11 et 21.Figures 5 and 6 show the connection / disconnection module in an initial position of the plugs 1 and 2 on the base 30 of the support 3, the pushers 12 and 22 themselves being in an initial position on their respective contacts 11 and 21.

On note que dans la position initiale de chacun des poussoirs sur ses deux contacts, les deux passages 13 ou 23 du poussoir sont situés juste en bout des fentes autodénudantes 14 ou 24 des contacts 11 et 21 et ne sont donc pas obturés par les contacts. On note également que chacun des poussoirs est mobile dans une seule direction sur ses deux contacts, depuis sa position initiale jusqu'à une position finale. Dans cette position finale du poussoir, les passages 13 ou 23 seront obturés par les contacts concernés.Note that in the initial position of each of the buttons on its two contacts, the two passages 13 or 23 of the pusher are located just end of the insulation displacement slots 14 or 24 of the contacts 11 and 21 and are not closed by the contacts. Note also that each of the pushers is movable in one direction on its two contacts, from its initial position to a final position. In this final position of the pusher, the passages 13 or 23 will be closed by the contacts concerned.

Un léger épaulement périphérique 11 A sur la partie intermédiaire des contacts 11 et deux petites dents latérales 21A sur la partie intermédiaire des contacts 21 permettent un maintien stable des contacts dans leur poussoir et n'autorisent le déplacement de chacun des poussoirs que dans une seule direction sur les contacts.A slight peripheral shoulder 11A on the intermediate portion of the contacts 11 and two small lateral teeth 21A on the intermediate portion of the contacts 21 allow stable holding of the contacts in their pusher and allow the movement of each of the pushers in one direction only on the contacts.

En outre, deux larges dents latérales 21 B sur les contacts plats 21 sont prévues sensiblement au même niveau que le fond de leur fente d'élasticité 25. Elles permettent, d'une part l'arrêt des contacts plats 21 dans leurs logements 61 dans le plot 5, par butée des dents 21 B contre le bord de l'ouverture rectangulaire 69 de ces logements. Elles permettent d'autre part l'arrêt du poussoir 22 dans sa position finale sur les contacts plats, par butée du fond des évidements 27 contre ces dents, alors que le poussoir 22 vient lui-même en butée contre le plot 6.In addition, two wide lateral teeth 21 B on the flat contacts 21 are provided substantially at the same level as the bottom of their elastic slot 25. They allow, on the one hand the stopping of the flat contacts 21 in their housings 61 in the stud 5, by abutment of the teeth 21 B against the edge of the rectangular opening 69 of these housing. On the other hand, they allow the pusher 22 to stop in its final position on the flat contacts, by abutting the bottom of the recesses 27 against these teeth, while the pusher 22 itself comes into abutment against the stud 6.

Le mode opératoire pour réaliser la connexion/déconnexion de deux paires de conducteurs isolés est précisé en se référant plus particulièrement à ces figures 5 et 6. La connexion de ces paires de conducteurs est réalisée en deux temps à l'aide d'une pince, par actionnement des deux poussoirs l'un après l'autre de leur position initiale à leur position finale sur leurs contacts et par enfichage résultant des deux fiches.The procedure for making the connection / disconnection of two pairs of insulated conductors is specified with particular reference to these FIGS. 5 and 6. The connection of these pairs of conductors is carried out in two stages using a clamp, by actuating the two pushers one after the other from their initial position to their final position on their contacts and by plugging resulting from the two cards.

Dans un premier temps, la première fiche 1 est retirée partiellement ou totalement du support 3 pour le raccordement à la deuxième fiche 2 de celle des paires de conducteurs qui lui est affectée. Le retrait partiel ou total de la première fiche 1 se fait en tirant sur le poussoir 12, qui entraîne avec lui ses deux contacts tubulaires. Il permet ainsi de libérer suffisamment ou totalement la face correspondante du plot pour l'appui de l'une des mâchoires de la pince contre cette face, alors que l'autre mâchoire prendra appui contre la face arrière du poussoir 22. Les deux fils conducteurs sont insérés dans les deux passages 23 du poussoir 22. La pince, mise en place pour assurer la prise du poussoir 22 et du plot 6 entre ses mâchoires, assure alors l'actionnement de ce poussoir 22 en position finale sur ses deux contacts 21, eux-mêmes alors en position finale dans les logements 61 du plot 6. La connexion résultante des deux conducteurs dans les fentes autodénudantes 24 des contacts 21 est dès lors permanente.In a first step, the first plug 1 is partially or completely withdrawn from the support 3 for connection to the second plug 2 of that of the pairs of conductors assigned to it. The partial or total withdrawal of the first plug 1 is done by pulling on the pusher 12, which carries with it its two tubular contacts. It thus makes it possible to release sufficiently or completely the corresponding face of the stud for the support of one of the jaws of the clamp against this face, while the other jaw will bear against the rear face of the pusher 22. The two leads are inserted into the two passages 23 of the pusher 22. The clamp, put in place to ensure the grip of the pusher 22 and the pad 6 between its jaws, then ensures the actuation of this pusher 22 in the final position on its two contacts 21, they themselves then in final position in the housing 61 of the stud 6. The resulting connection of the two conductors in the insulation displacement slots 24 of the contacts 21 is therefore permanent.

Dans un deuxième temps, les deux conducteurs isolés de l'autre paire sont insérés dans les deux passages 13 du poussoir 12 de la première fiche 1, cette première fiche étant partiellement enfichée dans le plot 6 après ou avant l'insertion des conducteurs dans les passages 13. Le premier poussoir 12 est alors actionné en position finale sur ses contacts tubulaires 11, à l'aide de la pince dont les mâchoires assurent la prise du poussoir 12 et du plot 6 ou du poussoir 22 entre elles. Il en résulte d'une part l'enfichage des contacts 11 à fond dans les logements 21 du plot et sur les contacts 61 déjà en position finale dans ceux-ci. Il en résulte d'autre part l'enfichage des tubulures 17 jusqu'au fond des logements 61, alors qu'en même temps les deux conducteurs sont engagés dans les fentes autodénudantes 14 des contacts 11. Le raccordement de ces deux conducteurs aux deux contacts 11 est alors également définitif.In a second step, the two insulated conductors of the other pair are inserted into the two passages 13 of the pusher 12 of the first plug 1, this first plug being partially plugged into the stud 6 after or before insertion. Conductors in the passages 13. The first pusher 12 is then actuated in its final position on its tubular contacts 11, with the aid of the clamp whose jaws ensure the grip of the pusher 12 and the pad 6 or the pusher 22 between them. As a result, the contacts 11 are fully plugged into the housings 21 of the stud and the contacts 61 already in the final position therein. On the other hand, this results in the plugging of the tubes 17 to the bottom of the housings 61, while at the same time the two conductors are engaged in the self-displacement slots 14 of the contacts 11. The connection of these two conductors to the two contacts It is then also definitive.

La connexion des deux paires de conducteurs raccordés aux fiches 1 et 2 résulte de l'enfichage de ces deux fiches l'une dans l'autre dans le plot 6. Leur déconnexion pour la coupure des lignes ainsi raccordées se fait par débrochage des fiches, à l'aide d'un tournevis ou analogue actionné en levier ou même au doigt, pour la séparation de l'une et/ou l'autre des fiches du plot 6. Une opération de test peut être éffectuée pareillement par désenfichage des fiches.The connection of the two pairs of conductors connected to the plugs 1 and 2 results from the plugging of these two plugs into one another in the stud 6. Their disconnection for the cutting of the lines thus connected is done by unplugging the plugs, using a screwdriver or the like operated lever or even the finger, for the separation of one and / or the other of the pins of the stud 6. A test operation can be performed similarly by unplugging the plugs.

La protection contre les surtensions est assurée par le module parasurtenseur (figure 2) alors embroché sur le plot 6.The overvoltage protection is provided by the surge protection module (FIG. 2) then seated on the stud 6.

Une protection des connexions dans le module de connexion/déconnexion, contre des agressions environnantes, peut également être assurée par l'utilisation et le confinement d'une graisse dans le module.Protection of the connections in the connection / disconnection module, against surrounding aggressions, can also be ensured by the use and confinement of a grease in the module.

Avantageusement, les poussoirs 12 et 13 sont transparents pour faciliter la vérification directe du raccordement correct des conducteurs dans les contacts.Advantageously, the pushers 12 and 13 are transparent to facilitate the direct verification of the correct connection of the conductors in the contacts.

Le concept simplifié du module de connexion/déconnexion, à nombre de pièces réduites et préassemblées pour former les deux fiches 1 et 2 enfichables dans le support et ainsi l'une dans l'autre, rend le mode opératoire très simple et aisé, sans organe spécial intégré à cet effet dans le module. Il réduit aussi en conséquence le coût du module et la durée du mode opératoire.The simplified concept of the connection / disconnection module, with a reduced number of parts and preassembled to form the two plugs 1 and 2 plug in the support and thus one in the other, makes the procedure very simple and easy, without any organ special integrated for this purpose in the module. It also reduces the cost of the module and the duration of the operating mode accordingly.

En variante donnée par rapport à la figure 1, le module de connexion/déconnexion sans protection associée comporte les deux fiches de connexion 1 et 2 et le support isolant 3 du module de la figure 2 et un cache, qui remplace alors le module parasurtenseur 7 et est utilisé pour venir coiffer le plot 6. Ce module de connexion/déconnexion peut-être équipé ou non des deux contacts 65 et du contact de masse 66 dans le plot 6. Un tel cache peut-être de forme analogue à celle du module parasurtenseur, ou de forme simplifiée.As a variant given with respect to FIG. 1, the connection / disconnection module without associated protection comprises the two connection plugs 1 and 2 and the insulating support 3 of the module of FIG. 2 and a mask, which then replaces the surge protection module 7. and is used to come to cap the pad 6. This connection / disconnection module may or may not be equipped with two contacts 65 and the ground contact 66 in the pad 6. Such a cache may be similar in shape to that of the module surge protector, or of simplified form.
