On connait des boîtes de dérivation dans lesquels les raccords perforants des liaisons conductrices sont fixés individuellement sur les phases et le neutre des câbles et sont indépendants du boîtier. Cependant, leur confection nécessite un nombre d'opérations assez important, et elles sont relativement encombrantes.Junction boxes are known in which the perforating connections of the conductive connections are individually fixed to the phases and the neutral of the cables and are independent of the housing. However, their preparation requires a fairly large number of operations, and they are relatively bulky.

La présente invention a pour but de procurer une boîte de dérivation que l'on puisse monter sur une câble principal sous tension, en un nombre réduit d'opérations simples, de manière que l'opérateur ne soit jamais en contact avec des parties conduc­trices de la connexion, et qui soit compacte et peu encombrante.The present invention aims to provide a junction box that can be mounted on a live main cable, in a reduced number of simple operations, so that the operator is never in contact with conductive parts of the connection, and which is compact and space-saving.

La boîte de dérivation selon l'invention est caractérisée en ce que les extrémités des conducteurs du ou des câbles dérivés, et les extrémités des liaisons métalliques de dérivation directement munies desdits raccords perforants sont disposées à l'intérieur d'un prolongement du premier élément isolant externe, intégré à celui-ci et formant un appendice sur lui.The junction box according to the invention is characterized in that the ends of the conductors of the derivative cable (s), and the ends of the metal bypass connections directly provided with said perforating connectors are arranged inside an extension of the first external insulating element, integrated into it and forming an appendage thereon.

- Les raccords perforants sur les conducteurs du câble principal comprennent deux raccords solidaires dudit premièr élément isolant externe et deux raccords solidaires dudit élément isolant interne, tous quatre amenés à perforer l'isolant du conducteur correspondant par vissage du ou des raccords mâles dudit élément isolant interne dans les raccords femelles dudit premier élément isolant externe.
- Une première paire de liaisons métalliques conductrices reliée à une première paire de conducteurs d'un ou des câbles dérivés est reliée par ailleurs directement à une première paire de conducteurs du câble principal, et une deuxième paire de liaisons métalliques conductrices reliée à une deuxième paire de conducteurs d'un ou des câbles dérivés est reliée à une deuxième paire de conducteurs du câble principal par l'intermédiaire des raccords mâles dudit élément isolant interne et femelles dudit premier élément isolant externe, après leur avance les uns dans les autres.It also preferably meets at least one of the following characteristics:
- The extension of said first insulating element projects away from said second external insulating element assembled on it.
- The connection of the derivative cable (s) is obtained by a perforating wedge by means of a conical insulating part, of cruciform cross section, driven back inside a cavity receiving the phase and neutral conductors of the derivative cable (s) , by an operating screw.

- The perforating connections on the conductors of the main cable include two connections integral with said first external insulating element and two connections integral with said internal insulating element, all four having to perforate the insulating material of the corresponding conductor by screwing the male connection (s) of said internal insulating element in the female connections of said first external insulating element.
- A first pair of conductive metal links connected to a first pair of conductors of one or more derived cables is also directly connected to a first pair of conductors of the main cable, and a second pair of conductive metal links connected to a second pair of conductors of one or more derived cables is connected to a second pair of conductors of the main cable via the male connections of said internal insulating element and the female of said first external insulating element, after their advance into each other.

Il est décrit ci-après, à titre d'exemple et en référence aux figures du dessin annexé, une boîte de dérivation pour câbles d'énergie à basse tension pour le raccordement d'un câble dérivé unique sur un câble principal sous 1KV.

  • La figure 1 représente en coupe l'ensemble du raccord.
  • La figure 2 représente à plus grande échelle une pièce isolante coulissante de coincement perforant des conducteurs du câble dérivé, en deux demi-coupes par un plan perpendiculaire au plan de la figure 1 selon son axe II-II, la demi-coupe supérieure avant raccordement, la demi-coupe inférieure après raccordement des conducteurs du câble dérivé.
It is described below, by way of example and with reference to the figures of the appended drawing, a junction box for low voltage power cables for the connection of a single branched cable to a main cable under 1KV.
  • Figure 1 shows in section the entire fitting.
  • Figure 2 shows on a larger scale an insulating sliding wedge perforating conductors of the branch cable, in two half-sections by a plane perpendicular to the plane of Figure 1 along its axis II-II, the upper half-section before connection , the lower half-cut after connection of the conductors of the branch cable.

Dans la figure 1, la boîte de dérivation compore deux éléments externes dits coquilles assemblées l'une à l'autre avec un autre élément interne dit également coquille. La coquille externe supérieure 3 est en matère isolante et est moulée dans une enveloppe métallique formant son revêtement métallique externe 1 ; la coquille externe inférieure 14 est en matière isolante, et également moulée dans une enveloppe métallique formant son revétement métallique externe 2. Dans la cavité formée entre celles-ci est disposée la coquille isolante interne 9. L'espace subsistant entre la coquille moulée externe supérieure 3 et la coquille isolante interne 9 est rempli d'une matière d'étanchéité visqueuse non conductrice 4, telle qu'un gel de pétrole.In Figure 1, the junction box has two external elements called shells assembled to each other with another internal element also called shell. The upper external shell 3 is made of insulating material and is molded in a metallic envelope forming its external metallic coating 1; the lower external shell 14 is made of insulating material, and also molded in a metallic envelope forming its external metallic coating 2. In the cavity formed between them is disposed the internal insulating shell 9. The space remaining between the upper external molded shell 3 and the internal insulating shell 9 is filled with a viscous non-conductive sealing material 4, such as petroleum gel.

Les coquilles moulées externes supérieure et inférieure s'emboî­tent l'une dans l'autre par des pourtours de profil en forme de chicane 20, qui permettent d'assurer la compression de la matière d'étanchéité 4 et empêchent l'eau de pénétrer dans la boîte. Des vis d'assemblage 27, 28 assurant leur fixation l'une sur l'autre.The upper and lower external molded shells fit into one another by baffle-shaped profile edges 20, which make it possible to ensure the compression of the sealing material 4 and prevent water from entering the box. Assembly screws 27, 28 ensuring their attachment to one another.

Le câble principal comprend trois conducteurs de phase 22, 23, 24 et un neutre 25, séparés par une entretoise isolante 26.The main cable comprises three phase conductors 22, 23, 24 and a neutral 25, separated by an insulating spacer 26.

La coquille inférieure isolante 14 comprend deux raccords perforants 5 et 6 pour les conducteurs 23, 24 du câble principal et deux raccords coulissants femelles 7A, 7B en métal conducteur pour son raccordement avec le coquille isolante interne 9. Elle comprend encore des dérivations qui seront décrites ci-après en liaison avec le seul câble dérivé considéré.The lower insulating shell 14 comprises two perforating connections 5 and 6 for the conductors 23, 24 of the main cable and two female sliding connections 7A, 7B made of conductive metal for its connection with the internal insulating shell 9. It also includes branches which will be described below in connection with the only branch cable considered.

La coquille interne isolante possède deux raccords perforants 10 et 11 pour le conducteur de phase 22 et le neutre 25 du câble principal. Ces raccords perforants sont reliés respectivement aux raccords coulissants mâles 12A, 12B, qui s'emboîtent dans les raccords coulissants femelles 7A, 7B de la coquille externe inférieure. L'assem­blage des raccords mâles sur les raccords femelles fixe la coquille interne 9 sur la coquille externe inférieure 14 et assure la perforation de l'isolant des trois phases et du neutre du câble principal et le contact avec leurs âmes conductrices. De tels raccords coulissants sont beaucoup moins encombrants et gênants pour les manoeuvres de montage que les connexions souples utilisées jusqu'à présent.The insulating internal shell has two perforating connections 10 and 11 for the phase conductor 22 and the neutral 25 of the main cable. These perforating fittings are respectively connected to the male sliding fittings 12A, 12B, which fit into the female sliding fittings 7A, 7B of the lower outer shell. The assembly of the male connections on the female connections fixes the internal shell 9 on the lower external shell 14 and ensures the perforation of the insulator of the three phases and the neutral of the main cable and the contact with their conductive cores. Such sliding connections are much less bulky and inconvenient for assembly operations than the flexible connections used until now.

Les vis 27, 28 d'assemblage des coquilles isolantes externes supérieure et inférieure 3 et 14 sont isolées des raccords coulis­sants de connexion, de sorte qu'aucun contact avec les phases sous tension n'est possible.The screws 27, 28 for assembling the upper and lower external insulating shells 3 and 14 are isolated from the sliding connection fittings, so that no contact with the live phases is possible.

Les dérivations sont constituées de la manière suivante. Le corps moulé isolant 14 présente un prolongement en saillie ou appendice de forme générale cylindrique, dans un renflement métallique externe 13 de la coquille métallique 2. Cette saillie contient quatre raccords perforants 15A, 15B, 15C, 15D. Les deux premiers 15A, 15B, portant sur les conducteurs de phase 30A, 30B du câble dérivé, sont reliés à deux liaisons conductrices 31A, 31B reliées par ailleurs aux raccords perforants 5 et 6. Les deux autres 15C, 15D, portant sur le conducteur de phase 30C et le neutre 30D, sont reliés par deux autres liaisons conductrices 31C et 31D aux raccords coulissants femelles 7A, 7B.The branches are made up as follows. The insulating molded body 14 has a projecting extension or appendage of generally cylindrical shape, in an external metal bulge 13 of the metal shell 2. This projection contains four perforating connections 15A, 15B, 15C, 15D. The first two 15A, 15B, relating to the phase conductors 30A, 30B of the branch cable, are connected to two conductive links 31A, 31B also connected to the perforating connectors 5 and 6. The other two 15C, 15D, relating to the conductor phase 30C and the neutral 30D, are connected by two other conductive links 31C and 31D to the female sliding connectors 7A, 7B.

Par ailleurs, une pièce isolante conique, de section droite en forme de croix, 16 séparant les conducteurs du câble dérivé assure la perforation des isolants des conducteurs de ce câble dérivé. A cet effet (voir figure 2) elle peut être poussée par une vis de manoeuvre 17. Cette pièce en avançant coince les phases et le neutre du câble dérivé contre les raccords perforants 15A, 15B, 15C, 15D (voir la demi-coupe inférieure de la figure). Les dents de ces raccords perforent alors les isolants des conducteurs et pénètrent dans leurs âmes conductrices, assurant ainsi la connexion électrique du câble dérivé, mais la vis de manoeuvre 17 est isolée électriquement des conducteurs, de sorte qu'aucun contact de l'opérateur avec les phases sous tension n'est possible.Furthermore, a conical insulating part, of cross section in the form of a cross, 16 separating the conductors of the branch cable ensures the perforation of the insulators of the conductors of this branch cable. To this end (see Figure 2) it can be pushed by a maneuvering screw 17. This piece by advancing wedges the phases and the neutral of the branched cable against the perforating connections 15A, 15B, 15C, 15D (see lower half-section of the figure). The teeth of these fittings then perforate the insulators of the conductors and penetrate their conductive cores, thus ensuring the electrical connection of the branch cable, but the operating screw 17 is electrically insulated from the conductors, so that no contact of the operator with live phases are not possible.

Il es évident que la boîte de dérivation peut recevoir deux câble dérivés, d'un côté et de l'autre respectivement de la boîte, les deux câbles dérivés aboutissant dans deux appendices 29 décalés symétriquement l'un de l'autre pour l'accès aux vis de manoeuvre 17.It is obvious that the junction box can receive two derived cables, on one side and the other respectively of the box, the two derived cables ending in two appendages 29 offset symmetrically from one another for access to the operating screws 17.
