Definitions
- Patent FR-A-2,541,049 relates to a device of this kind, characterized in that the tubular connection element has a first split end part whose external transverse dimensions are such that it can penetrate into the second split end part of another tubular connection element, similar to the first, guide means being provided between at least one interior part of the insulating support, and each tubular connection element that it supports, to allow relative movement, axial but not angular , between the insulating support and each tubular element, displacement means being provided, individually for each tubular connection element, to ensure by this relative axial displacement, the connection, respectively the connection and the disconnection, between at least one of the two transverse slots of the latter, slot which extends through the two opposite thereof, and at least one conductor dis placed in the corresponding passage which extends transversely to the insulating support in the extension of each of the two ends of the transverse slot.
- the devices of this type described and represented in patent FR-A-2,541,049 are generally equipped with an operating member, such as a screw, by tubular connection element, or by stacking of tubular connection elements inserted. into each other.
- an operating member such as a screw
- tubular connection element or by stacking of tubular connection elements inserted. into each other.
- connection device overcomes these drawbacks. It is characterized in that it comprises two identical and parallel tubular connection elements, or two parallel and identical stacks of nesting tubular connection elements, both having a common insulating support, said common insulating support being constituted by a half lower sleeve mounted on a common electrically conductive base connected to the earth of the installation, and an insulating upper half-sleeve covering the two parallel tubular elements, or the two parallel stacks of nesting tubular elements, this upper half-sleeve being traversed , parallel to the two tubular elements or tubular stacks, and between them, by an electrically conductive screw, arranged so as to be able, by coming to be screwed into a corresponding threaded orifice of said common conductive base, ensuring the bringing together of said upper and lower half-sockets.
- Each of the modules 1,2,3 shown differs from the modules described in patent FR-A-2,541,049 by the fact that it is always double, that is to say that it comprises two devices according to the patent FR-A-2.541.049 parallel and coupled, that its lower insulating support is constituted by a double piece 8, intended to receive the two lower wires, which is fixed on a common metal bar 9, or metal base, connected to earth of the installation, and that the displacement means making it possible, by respective approximation of the upper half-socket 4 and the lower half-socket 8, to tighten the module and thereby ensure the insulation displacement connection of the lower wires and / or higher, is made up by a metal screw 10 crossing from top to bottom the central part of the module, between the two parallel tubular elements and the two parallel stacks of nesting tubular elements, to be screwed into the metal base 9 and thereby ensure the tightening vertical of the different half-sockets 4,8 or 4,5,8, or 4,6,8 constituting the module 1,2 or
- FIG. 2 represents the simplest module 1, as it is delivered to the user before any assembly of wires.
- the common insulating half-sleeve 4 which covers the entire module and receives the head of the central metal screw 10, the latter being screwed into the metal bar 9 to ensure the tightening of the cover 4 against the lower insulating half-sleeve 8, the latter being mounted, by fixing members 11 which are difficult to remove, on the bar 9 as shown.
- the upper half-sleeve 4 obviously includes two tubular channels 12, 13 intended to receive the two upper wires to be connected, and likewise the lower half-sleeve 8 comprises two tubular channels 14, 15 intended to receive the two lower wires 16, 17 to connect.
- the module 1 is equipped with two insulating connection tubular elements 18,19, split at the bottom and at the top as described in patent FR-A-2,541,049 in alignment with the tubular channels 12 to 15.
- these tubular elements 18, 19 are parallel and intimately coupled by the fact that on the one hand their lower half-socket 8 is common and double, and that on the other hand their upper half-socket 4 is also common, double, and provided of a single central operating member constituted by the metal screw 10 ensuring not only the tightening, but also the ground connection separating the two tubular connection elements 18 and 19.
- the module is delivered equipped with two annular shims 20 and 21 allowing the two tubular elements 18 and 19 to be held in the high position as shown, and thereby avoiding accidental crimping of the lower split part of the elements 18 and 19 on the two axial and protruding central parts 22 of the lower half-sleeve 8.
- the non-threaded upper part 23 of the screw 20 is held in the half - upper sleeve 4 using a metal sleeve 24, crimped on the part 23, free to rotate in the half-sleeve 4 and forming a shoulder 25 opposing the withdrawal of the screw 10, as can be clearly seen in the drawing.
- the clamping screw 10 is completely unscrewed, which first of all causes the spacing of the upper half-bush 4 relative to the lower half-bush 8 then, the screw 10 being completely removed from the bar 9, which allows manual separation of the half-sockets 4 and 8, in their relative position in FIG. 4.
- the screw 10 is then unscrewed again, which again makes it possible to separate the upper part 4 from the lower part 8.
- the two upper wires 26, 27 are then introduced into the two channels 12, 13. The respective positions and situations are then at this stage exactly those shown in FIG. 4.
- the cap 4 is then again placed on the lower part 8, and the screw 10 is fully screwed into the metal bar 9 which ensures the insulation displacement connection of the upper wires 26, 27 in the upper slots of the tubular elements 18 and 19.
- the situation obtained is then that shown in FIG. 6.
- the module 1 therefore allows the disconnection of the upper wires 26, 27 but not the disengaging, or cutting, of this set of upper wires, disengaging which can only be achieved by the uncoupling of two nesting tubular elements.
- the simple module 1 differs from the cut-off module 2 mainly by the fact that it is added on the module 2 a " intermediate "half-sleeve 5" comprising two additional insulating tubular elements 28,29, the upper split parts of which are intended to receive the two upper wires 26,27 and the lower split parts of which are intended to be inserted in the upper split parts tubular elements 18 and 19, thus ensuring the possibility of disengaging, or cut desired.
- the module 2 is, on delivery, equipped with the same shims 20, 21 as the module 1.
- module 2 is delivered with its shims 20 and 21. We therefore begin, to remove these shims, to unscrew the screw 10 until its threaded end comes to escape from the bar 9, the screw 10 then rotating in a vacuum. We then manually pull the set of two half-sockets or rings 1.5, to separate them from the lower ring 8, fixed in position on the bar 9. We remove and discard the two shims 20 and 21. We engage as for in the case of module 1, the two lower wires 16.17 in the two parallel guns 14.15 of the lower stage 8.
- the screw 10 is then unscrewed again and the assembly 1.5 is again detached manually from the lower stage 8.
- Figure 8 shows a variant of the screw 10 of Figure 7, avoiding to provide a lower slot 37 for screwing against the direction.
- the screw 10 is continuously pushed upwards by a spring 40 pressing on the upper part of the nut 31, so that it comes, when it escapes from the bar 9, immediately engaged on the thread of the nut 31.
- the module 3 of FIG. 1 differs from module 2 by the fact that its intermediate stage 6, if it is identical to stage 5 as regards its part located in alignment axial with stages 4 and 8, has a large lateral extension 7, of parallelepipedal shape, provided with a removable inspection cover 41, and containing a surge arrester 42.
- the surge arrester, or surge arrester 42 has its two terminals 43, 44 plugged into the aligned slots, respectively upper and lower, of the elements 28.18 for the first terminal 43 and 29.19 for the second terminal 44, and has its earth terminal 45 coming to bear firmly against the body of the screw 10.
- the housing 7 containing the arrester 42 is integrally molded with the body of the intermediate half-sleeve 6.
- this housing 7 can be independent of the body 6, and it is detachably plugged into this body 6 for example by the terminals 43, 44, and possibly 45, or else the housing 7 does not exist at all and it is the arrester itself which is detachably plugged onto this body 6 by means of the terminals 43,44, and possibly 45.

Description
La présente invention concerne des dispositifs de connexion, du type comportant au moins un élément tubulaire de connexion, conducteur de l'électricité, supporté par un support électriquement isolant, élément dont la première et la seconde partie extrême, opposées l'une de l'autre, comportent respectivement une première et une seconde fente transversale constituant des moyens de connexion autodénudants susceptibles de recevoir chacun au moins un conducteur, un passage étant prévu dans le support isolant, vis-à-vis d'au moins la seconde fente transversale, pour y loger le conducteur, selon le brevet FR-A-2.541.049 (= GB-A-2 135 530).The present invention relates to connection devices, of the type comprising at least one tubular connection element, electrically conductive, supported by an electrically insulating support, element of which the first and second end portions, opposite one of the other, respectively comprise a first and a second transverse slot constituting insulation displacement connection means capable of each receiving at least one conductor, a passage being provided in the insulating support, opposite at least the second transverse slot, for accommodate the conductor, according to patent FR-A-2,541,049 (= GB-A-2,135,530).
Le brevet FR-A-2.541.049 concerne un dispositif de ce genre, caractérisé en ce que l'élément tubulaire de connexion a une première partie extrême fendue dont les dimensions transversales extérieures sont telles qu'elle puisse pénétrer dans la seconde partie extrême fendue d'un autre élément tubulaire de connexion, similaire au premier, des moyens de guidage étant prévus entre au moins une partie intérieure du support isolant, et chaque éléments tubulaire de connexion qu'il supporte, pour permettre un déplacement relatif, axial mais non angulaire, entre le support isolant et chaque élément tubulaire, des moyens de déplacement étant prévus, individuellement pour chaque élément tubulaire de connexion, pour assurer par ce déplacement axial relatif, la connexion, respectivement la connexion et la déconnexion, entre au moins l'une des deux fentes transversales de ce dernier, fente qui s'étend à travers les deux opposées de celui-ci, et au moins un conducteur disposé dans le passage correspondant qui s'étend transversalement au support isolant dans le prolongement de chacune des deux extrémités de la fente transversale.Patent FR-A-2,541,049 relates to a device of this kind, characterized in that the tubular connection element has a first split end part whose external transverse dimensions are such that it can penetrate into the second split end part of another tubular connection element, similar to the first, guide means being provided between at least one interior part of the insulating support, and each tubular connection element that it supports, to allow relative movement, axial but not angular , between the insulating support and each tubular element, displacement means being provided, individually for each tubular connection element, to ensure by this relative axial displacement, the connection, respectively the connection and the disconnection, between at least one of the two transverse slots of the latter, slot which extends through the two opposite thereof, and at least one conductor dis placed in the corresponding passage which extends transversely to the insulating support in the extension of each of the two ends of the transverse slot.
Les dispositifs de ce type décrits et représentés dans le brevet FR-A-2.541.049 sont généralement équipés d'un organe de manoeuvre, tel qu'une vis, par élément tubulaire de connexion, ou par empilage d'éléments tubulaires de connexion enfichés les uns dans les autres. On aboutit ainsi à une construction assez onéreuse, alors qu'en réalité on réalise toujours simultanément des connexions en agissant en même temps sur deux éléments tubulaires de connexion placés côte à côte, ou sur deux empilages d'éléments tubulaires de connexion placés côte à côte.The devices of this type described and represented in patent FR-A-2,541,049 are generally equipped with an operating member, such as a screw, by tubular connection element, or by stacking of tubular connection elements inserted. into each other. This results in a fairly expensive construction, when in reality we always make connections simultaneously by acting at the same time on two tubular connection elements placed side by side, or on two stacks of tubular connection elements placed side by side .
Par ailleurs, tous ces dispositifs ne permettent pas à eux seuls d'assurer une connexion de masse, alors qu'une borne de masse entre deux connexions adjacentes est souvent nécessaire, et que dans ce dernier cas l'on est conduit, avec ces dispositifs, à prévoir une troisième borne de connexion médiane pour la masse, comme c'est en particulier le cas lorsque l'on désire installer un para-surtension entre les deux bornes de connexion faisant partie d'éléments tubulaires parallèles, ou de piles d'éléments tubulaires parallèles.Furthermore, all of these devices do not by themselves make it possible to provide a ground connection, whereas a ground terminal between two adjacent connections is often necessary, and only in the latter case one is led, with these devices, to provide a third median connection terminal for the ground, as is in particular the case when it is desired to install a para-overvoltage between the two connection terminals forming part of parallel tubular elements, or stacks of parallel tubular elements.
Le dispositif de connexion selon la présente invention permet de pallier ces inconvénients. Il est caractérisé en ce qu'il comporte deux éléments tubulaires de connexion parallèles et identiques, ou deux empilages parallèles et identiques d'éléments tubulaires de connexion gigognes, ayant tous deux un support isolant commun, ledit support isolant commun étant constitué par une demi-douille inférieure montée sur une embase électriquement conductrice commune reliée à la masse de l'installation, et une demi-douille supérieure isolante coiffant les deux éléments tubulaires parallèles, ou les deux empilages parallèles d'éléments tubulaires gigognes, cette demi-douille supérieure étant traversée, parallèlement aux deux éléments tubulaires ou empilages tubulaires, et entre ceux-ci, par une vis conductrice de l'électricité, agencée de manière à pouvoir, en venant se visser dans un orifice taraudé correspondant de ladite embase conductrice commune, assurer le rapprochement desdites demi-douilles supérieure et inférieure.The connection device according to the present invention overcomes these drawbacks. It is characterized in that it comprises two identical and parallel tubular connection elements, or two parallel and identical stacks of nesting tubular connection elements, both having a common insulating support, said common insulating support being constituted by a half lower sleeve mounted on a common electrically conductive base connected to the earth of the installation, and an insulating upper half-sleeve covering the two parallel tubular elements, or the two parallel stacks of nesting tubular elements, this upper half-sleeve being traversed , parallel to the two tubular elements or tubular stacks, and between them, by an electrically conductive screw, arranged so as to be able, by coming to be screwed into a corresponding threaded orifice of said common conductive base, ensuring the bringing together of said upper and lower half-sockets.
De toute façon, l'invention sera bien comprise, et d'autres caractéristiques avantageuses apparaîtront, au cours de la description suivante de quelques exemples de réalisation, en référence aux dessins annexés dans lesquels :

En se reportant tout d'abord à la figure 1, on a représenté, à titre d'illustration non limitative, trois dispositifs de connexion 1,2,3 conformes à la présente invention :
- un module de connexion autodénudant 1 simple, ne comportant que deux éléments tubulaires de connexion, parallèles et autorisant seulement la déconnexion des deux fils supérieurs, et non pas le désenfichage de la partie supérieure 4 contenant ces deux fils,
- un module de connexion autodénudant 2 plus perfectionné, comportant deux empilages parallèles de chacun deux éléments tubulaires de connexion gigognes, ce qui autorise le désenfichage, ou "coupure", de la partie supérieure 4 contenant les deux fils supérieurs,
- un module de
connexion 3 à coupure, différant dumodule 2 par le fait que la demi-douille intermédiaire 5 de ce module 2 y est remplacée par une demi-douille 6 contenant undispositif 7 de protection contre les surtensions, dit ordinairement "parafoudre" on plus généralement "parasurtension".
- a simple insulation
displacement connection module 1, comprising only two tubular connection elements, parallel and allowing only the disconnection of the two upper wires, and not the disengaging of theupper part 4 containing these two wires, - a more improved insulation
displacement connection module 2, comprising two parallel stacks of each two tubular nesting connection elements, which allows theupper part 4 containing the two upper wires to be disengaged, or "cut", - a
connection module 3 with cut-off, differing frommodule 2 by the fact that the intermediate half-socket 5 of thismodule 2 is replaced there by a half-socket 6 containing adevice 7 for protection against overvoltage, usually called "surge arrester" more generally "surge protection".
Chacun des modules 1,2,3 représenté se différencie des modules décrits dans le brevet FR-A-2.541.049 par le fait qu'il est toujours double, c'est-à-dire qu'il comporte deux dispositifs selon le brevet FR-A-2.541.049 parallèles et accouplés, que son support isolant inférieur est constitué par une pièce double 8, destinée à recevoir les deux fils inférieurs, qui est fixée sur une barrette métallique commune 9, ou embase métallique, reliée à la masse de l'installation, et que le moyen de déplacement permettant, par rapprochement respectif de la demi-douille supérieure 4 et de la demi-douille inférieure 8 de serrer le module et par là même d'assurer la connexion autodénudante des fils inférieurs et/ou supérieurs, est constitué par une vis métallique 10 traversant du haut en bas la partie centrale du module, entre les deux éléments tubulaires parallèles et les deux empilages parallèles d'éléments tubulaires gigognes, pour venir se visser dans l'embase métallique 9 et par là même assurer le serrage vertical des différentes demi-douilles 4,8 ou 4,5,8, ou 4,6,8 constituant le module 1,2 ou 3 considéré.Each of the
Chacun des modules doubles 1,2 et 3, sera maintenant décrit plus en détails, avec son mode de fonctionnement, en référence aux figures suivantes.Each of the
La figure 2 représente le module le plus simple 1, tel qu'il est livré à l'utilisateur avant tout montage de fils. On reconnaît de prime abord sur cette figure la demi-douille isolante commune 4, qui coiffe l'ensemble du module et reçoit la tête de la vis centrale métallique 10, celle-ci venant se visser dans la barrette métallique 9 pour assurer le serrage de la coiffe 4 contre la demi-douille isolante inférieure 8, celle-ci étant montée, par des organes de fixation 11 difficilement amovibles, sur la barrette 9 comme représenté. La demi-douille supérieure 4 comporte bien évidemment deux canaux tubulaires 12,13 destinés à recevoir les deux fils supérieurs à connecter, et de même la demi-douille inférieure 8 comporte deux canaux tubulaires 14,15 destinés à recevoir les deux fils inférieurs 16,17 à connecter. Le module 1 est équipé de deux éléments tubulaires de connexion autodénudants 18,19, fendus en bas et en haut comme décrit dans le brevet FR-A-2.541.049 en alignement avec les canaux tubulaires 12 à 15. Conformément à l'invention, ces éléments tubulaires 18,19 sont parallèles et intimement accouplés par le fait que d'une part leur demi-douille inférieure 8 est commune et double, et que d'autre part leur demi-douille supérieure 4 est également commune, double, et munie d'un unique organe central de manoeuvre constitué par la vis métallique 10 assurant non seulement le serrage, mais encore la connexion de masse séparant les deux éléments tubulaires de connexion 18 et 19.FIG. 2 represents the
Tel qu'il est représenté sur la figure 2, le module est livré équipé de deux cales annulaires 20 et 21 permettant de maintenir les deux éléments tubulaires 18 et 19 en position haute comme représenté, et par là même, d'éviter un sertissage accidentel de la partie fendue inférieure des éléments 18 et 19 sur les deux parties centrales axiales et protubérantes 22 de la demi-douille inférieure 8. Avantageusement, pour des raisons pratiques évidentes, la partie supérieure non filetée 23 de la vis 20 est maintenue dans la demi-douille supérieure 4 à l'aide d'un manchon métallique 24, serti sur la partie 23, libre en rotation dans la demi-douille 4 et formant un épaulement 25 s'opposant au retrait de la vis 10, comme on le voit nettement sur le dessin.As shown in Figure 2, the module is delivered equipped with two
Les figures 4 et 6, auxquelles on se référera maintenant, permettent de comprendre le fonctionnement du module simple 1 de l'invention.Figures 4 and 6, to which reference will now be made, make it possible to understand the operation of the
Ayant en main le module de la figure 2, on dévisse totalement la vis de serrage 10, ce qui entraîne tout d'abord l'écartement de la demi-douille supérieure 4 par rapport à la demi-douille inférieure 8 puis, la vis 10 étant totalement sortie de la barrette 9, ce qui permet la séparation manuelle des demi-douilles 4 et 8, dans leur position relative de la figure 4.Having in hand the module of FIG. 2, the
A ce stade, aucun fil n'est encore connecté, ce qui n'est pas le cas de ce qui est représenté sur la figure 4. On introduit alors, après avoir jeté les cales 20 et 21, les deux fils inférieurs 16,17 dans les canaux inférieurs 14,15. On replace la demi-douille 4 sur la demi-douille 8, et l'on visse à fond la vis 10 dans la barrette métallique 9 ce qui entraîne la connexion autodénudante des fils 14,15 sur les éléments fendus 18,19, et le sertissage de ces derniers sur les protubérances axiales 22 de la demi-douille 8, comme on le voit d'ailleurs sur la partie inférieure de la figure 4.At this stage, no wire is yet connected, which is not the case of what is shown in FIG. 4. Then, after having thrown the
On dévisse alors à nouveau la vis 10, ce qui permet de séparer à nouveau la partie supérieure 4 de la partie inférieure 8. On introduit alors les deux fils supérieurs 26,27 dans les deux canaux 12,13. Les positions et situations respectives sont alors à ce stade exactement celles représentées sur la figure 4.The
On place alors à nouveau le chapeau 4 sur la partie inférieure 8, et l'on visse à fond la vis 10 dans la barrette métallique 9 ce qui assure la connexion autodénudante des fils supérieurs 26,27 dans les fentes supérieures des éléments tubulaires 18 et 19. La situation obtenue est alors celle représentée sur la figure 6.The
Pour déconnecter alors les deux fils supérieurs 26,27, il faut dévisser complètement la vis de manoeuvre 10, puis tirer sur les fils 26 et 27 pour les extraire. On peut alors, si l'on veut, effectuer la connexion d'une autre paire de fils supérieurs.To disconnect the two
Le module 1 permet donc la déconnexion des fils supérieurs 26,27 mais pas le désenfichage, ou coupure, de cet ensemble de fils supérieurs, désenfichage qui ne peut être réalisé que par le désaccouplement de deux éléments tubulaires gigognes.The
On décrira maintenant en détails, à l'aide des figures 3,5 et 7, le module 2 qui permet de réaliser un tel désenfichage, ou "coupure".We will now describe in detail, with the aid of Figures 3,5 and 7, the
En comparant les figures 2 et 3 d'une part, et 4 et 5 d'autre part, on voit que le module simple 1 se différencie du module à coupure 2 principalement par le fait qu'il est rajouté sur le module 2 une "demi-douille" intermédiaire 5 comportant deux éléments tubulaires autodénudants supplémentaires 28,29, dont les parties fendues supérieures sont destinées à recevoir les deux fils supérieurs 26,27 et dont les parties fendues inférieures sont destinées à venir s'enficher dans les parties fendues supérieures des éléments tubulaires 18 et 19, permettant ainsi d'assurer la possibilité de désenfichage, ou coupure souhaitée.By comparing Figures 2 and 3 on the one hand, and 4 and 5 on the other hand, we see that the
Comme on le voit sur la figure 3, le module 2 est, à la livraison, équipé des mêmes cales 20,21 que le module 1.As can be seen in FIG. 3, the
Dans l'orifice central axial 30 de la demi-douille est serti un boulon tubulaire métallique 31 dont le pas de filetage et le diamètre intérieurs sont les mêmes que ceux du perçage 92 de la barrette 9, qui est destiné à recevoir l'extrémité filetée de la vis 10.In the central
Enfin, la vis 10 utilisée pour le module à coupure 2 présente quelques différences avec celle équipant le module simple 1.Finally, the
Elle est tout d'abord bien évidemment plus longue que la vis précédente. Par ailleurs, elle est munie, successivement du bas de la vis vers le haut, c'est-à-dire jusqu'à sa tête :
- d'une extrémité filetée 32, dimensionnée pour venir au maximum se visser dans la
barrette 9 sur une longueur de filetage L₁, d'une partie 33, lisse de préférence, de plus faible diamètre de manière à pouvoir coulisser sans encombre dans l'écrou 31 ; la longueur de la partie lisse 33 est égale à la longueur L₂ de l'écrou 31, augmentée d'une longueur L₃ qui doit être supérieure, préférentiellement légèrement supérieure, à la longueur L₁ définie ci-dessus,- d'une partie épaulée 34, dont l'épaulement supérieur 35 est éloignée, lorsque la vis 10 est vissée à fond dans
la barrette 9,d'un rétrécissement 38 du perçage axial 36 duchapeau 4, d'une distance L₄ supérieure, préférentiellement légèrement supérieure à la distance L₃ ci-dessus définie, - d'une partie lisse 23 et de la tête de vis, analogues à celles de la vis équipant le
module 1.
- a threaded
end 32, dimensioned so as to be screwed into thebar 9 as much as possible over a thread length L₁, - a
portion 33, preferably smooth, of smaller diameter so as to be able to slide smoothly in thenut 31; the length of thesmooth part 33 is equal to the length L₂ of thenut 31, increased by a length L₃ which must be greater, preferably slightly greater, than the length L₁ defined above, - a
shoulder portion 34, theupper shoulder 35 of which is distant, when thescrew 10 is screwed fully into thebar 9, a narrowing 38 of theaxial bore 36 of thecap 4, by a distance L₄ greater, preferably slightly greater than the distance L₃ above defined, - a
smooth part 23 and the screw head, similar to those of the screw fitted to themodule 1.
Le fonctionnement du module à coupure 2 est le suivant :
Comme on le voit sur la figure 3, le module 2 est livré avec ses cales 20 et 21. On commence donc, pour retirer ces cales, à dévisser la vis 10 jusqu'à ce que son extrémité filetée vienne s'échapper de la barrette 9, la vis 10 tournant alors dans le vide. On tire alors manuellement l'ensemble des deux demi-douilles ou bagues 1,5, pour les séparer de la bague inférieure 8, fixe en position sur la barrette 9. On retire et jette les deux cales 20 et 21. On engage comme pour le cas du module 1 les deux fils inférieurs 16,17 dans les deux canons parallèles 14,15 de l'étage inférieur 8.The operation of the cut-off
As seen in Figure 3,
On pose alors à nouveau l'ensemble des deux étages supérieurs 1,5 sur l'étage inférieur 8, et l'on vient visser à fond la vis 10 dans la barrette 9. Cette opération permet, comme c'était le cas pour le module 1, de connecter définitivement les deux fils inférieurs, comme ils sont représentés sur la figure 5, tout en sertissant la partie inférieure des deux éléments 18,19 sur les excroissances 22 de l'étage inférieur 8.Then the whole of the two upper stages 1.5 is again placed on the
On dévisse alors à nouveau la vis 10 et l'on désolidarise à nouveau manuellement l'ensemble 1,5 de l'étage inférieur 8.The
En introduisant alors un tournevis dans une fente située à l'extrémité de la vis 10 opposée à sa tête, on vient enclencher le filetage de l'extrémité 32 de la vis dans le taraudage du boulon tubulaire 31 et, en vissant par cette fente 37, on vient placer l'épaulement 35 en appui axial contre le rétrécissement 38. En continuant à visser dans le même sens, on vient séparer les deux bagues, ou demi-douilles, ou étages, 4 et 5, ce qui permet d'introduire les deux fils supérieurs 26,27 dans les canons correspondants 12 et 13 de la bague supérieure 4.By then inserting a screwdriver into a slot located at the end of the
On replace alors le couple de bagues supérieures 4,5 sur la bague inférieure 8, et l'on visse la vis 10 par sa tête. Son extrémité filetée 32 vient d'abord s'échapper de l'écrou 31, puis vient en prise dans le taraudage du perçage 92. En vissant à fond la vis 10 dans la barrette 9, on assure le pressage des trois étages 4,5 et 8 l'un contre l'autre, ce qui entraîne la connexion autodénudante des fils supérieurs 26 et 27.Then replace the pair of upper rings 4.5 on the
Pour réaliser ensuite une coupure, c'est-à-dire une séparation par désenfichage du couple de fils supérieurs 26,27 par rapport au couple de fils inférieurs 16,17, il faut dévisser la vis 10 jusqu'à ce qu'elle tourne dans le vide, puis tirer manuellement sur l'ensemble des deux étages supérieurs 4,5 pour le désaccoupler, par désenfichage, de l'étage inférieur 8.To then make a cut, that is to say a separation by disengaging the pair of
La figure 8 montre une variante de la vis 10 de la figure 7, évitant de prévoir une fente inférieure 37 de vissage à contre-sens. Selon cette variante, la vis 10 est en permanence poussée vers le haut par un ressort 40 s'appuyant sur la partie supérieure de l'écrou 31, de sorte qu'elle vient, lorsqu'elle s'échappe de la barrette 9, immédiatement en prise sur le filetage de l'écrou 31.Figure 8 shows a variant of the
En se reportant enfin aux figures 9 et 10, le module 3 de la figure 1 se différencie du module 2 par le fait que son étage intermédiaire 6, s'il est identique à l'étage 5 en ce qui concerne sa partie située en alignement axial avec les étages 4 et 8, comporte un important prolongement latéral 7, de forme parallélépipèdique, munie d'un couvercle de visite amovible 41, et contenant un parafoudre 42.Referring finally to FIGS. 9 and 10, the
Comme on le voit sur les figures 9 et 10, le parafoudre, ou parasurtension 42 a ses deux bornes 43,44 enfichées dans les fentes alignées, respectivement supérieure et inférieure, des éléments 28,18 pour la première borne 43 et 29,19 pour la deuxième borne 44, et a sa borne de masse 45 venant fermement en appui contre le corps de la vis 10.As can be seen in FIGS. 9 and 10, the surge arrester, or
Dans le cas des figures 9 et 10, le boîtier 7 contenant le parafoudre 42 est moulé d'un seul bloc avec le corps de la demi-douille intermédiaire 6. Selon deux variantes possibles de réalisation, ou bien ce boîtier 7 peut être indépendant du corps 6, et il vient s'enficher de manière amovible dans ce corps 6 par exemple par les bornes 43,44, et éventuellement 45, ou bien le boîtier 7 n'existe pas du tout et c'est le parafoudre lui-même qui vient s'enficher de manière amovible sur ce corps 6 au moyen des bornes 43,44, et éventuellement 45.In the case of Figures 9 and 10, the
