A l'extrémité libre du loquet 24 est attelée de façon à pouvoir se déplacer en translation sur une course déter­minée, une clé secondaire 23.A lock 19 is mounted on the outer face of the cover 17. This lock, known in itself, is part of an overall security system on a site. It has a so-called "flying" key 22 and is arranged to cooperate with a latch 24 pivotally mounted on a rod 25, itself fixed perpendicularly to a face of the flap 20 opposite to that carrying the flange 21. At the free end of the latch 24 is coupled so as to be able to move in translation over a determined stroke, a secondary key 23.

L'introduction de la clé secondaire 23 dans un orifice spécifique du verrou 19 autorise la rotation de la clé volante 22 en vue du verrouillage de la clé secondaire 23, puis le retrait de la clé volante. On pourra notamment choisir un verrou de la Société CASTELL-TRAYVOU, portant la référence MOL 85.The introduction of the secondary key 23 into a specific orifice of the lock 19 authorizes the rotation of the flying key 22 for locking the secondary key 23, then the removal of the flying key. We can in particular choose a lock from CASTELL-TRAYVOU, bearing the reference MOL 85.

Trois tiges 31, 32, 33 sont montées de façon juxtaposée entre les deux cornières 6, 7 parallèlement à celles-ci. Chaque tige est maintenue par ses extrémités au moyen de deux supports 34, 35 de façon à pouvoir se déplacer en translation selon son axe. Elle est rappelée dans un sens par un ressort hélicoïdal 36 monté dans le support 34. Les deux supports 34, 35 sont fixés res­pectivement sur les côtés 3 et 2 du cadre 1. Chaque tige présente trois gorges circulaires 37 réparties sur sa longueur.Three rods 31, 32, 33 are mounted juxtaposed between the two angles 6, 7 parallel to them. Each rod is held by its ends by means of two supports 34, 35 so as to be able to move in translation along its axis. It is recalled in one direction by a helical spring 36 mounted in the support 34. The two supports 34, 35 are fixed respectively on the sides 3 and 2 of the frame 1. Each rod has three circular grooves 37 distributed over its length.

Sur le support de jonction de câbles, et au droit de chaque tige 31, 32, 33, sont montés trois ressorts à lame 38, 39, 40. Chaque ressort à lame pré­sente une extrémité 41 fixée à plat soit sur une plaque 43 montée sur le cadre entre ses côtés longitudinaux 2, 3 et les cornières 6, 7 (pour les ressorts 38, 39), soit sur le côté longitudinal 2 (pour le ressort 40). Chaque ressort à lame forme une boucle qui présente deux trous 44, 45 grâce auxquels celle-ci est traversée par la tige correspondante, et se termine par une extré­mité libre 42 traversant perpendiculairement la plaque 43 (ressorts 38, 39) ou le côté longitudinal 2 du cadre 1 (ressort 40), dans une fente 46 ménagée dans ceux-ci.Three leaf springs 38, 39, 40 are mounted on the cable junction support, and in line with each rod 31, 32, 33. Each leaf spring has one end 41 fixed flat either on a plate 43 mounted on the frame between its longitudinal sides 2, 3 and the angles 6, 7 (for the springs 38, 39), or on the longitudinal side 2 (for the spring 40). Each leaf spring forms a loop which has two holes 44, 45 through which the latter is traversed by the corresponding rod, and ends with a free end 42 perpendicularly crossing the plate 43 (springs 38, 39) or the longitudinal side 2 of the frame 1 (spring 40), in a slot 46 formed therein.

Dans la position où le ressort hélicoïdal 36 est détendu, les gorges 37 de chaque tige sont disposées au droit des trous 45 des ressorts à lame. L'élasticité des ressorts à lame tend à éloigner ceux-ci du support de jonction de câbles, de sorte que le bord de leurs trous 45 bute contre le fond des gorges 37 des tiges: les tiges 31, 32, 33 s'étendent en partie à l'extérieur du cadre 1 et ne peuvent alors pas être déplacées en direction du support 34. Il en résulte qu'elles s'opposent à la fermeture du couvercle 17 qui bute contre leurs extrémités.In the position where the helical spring 36 is relaxed, the grooves 37 of each rod are arranged in line with the holes 45 of the leaf springs. The elasticity of the leaf springs tends to separate them from the cable junction support, so that the edge of their holes 45 abuts against the bottom of the grooves 37 of the rods: the rods 31, 32, 33 extend in part outside the frame 1 and cannot then be moved in the direction of the support 34. As a result, they oppose the closing of the cover 17 which abuts against their ends.

Lorsqu'un élément de jonction de câbles 50 est, comme précisé par la suite, correctement disposé dans le support de jonction de câble, il pousse le ressort à lame correspondant 38 vers le support de jonction de câble, ce qui a pour effet de déceler le trou 45 du ressort à lame par rapport à la gorge 37 de la tige 31. Cette tige ne bute alors plus contre le ressort à lame et peut être déplacée vers le support 34, autorisant ainsi la fermeture du couvercle 17.When a cable joining element 50 is, as explained below, correctly placed in the cable joining support, it pushes the leaf spring corresponding 38 to the cable junction support, which has the effect of detecting the hole 45 of the leaf spring relative to the groove 37 of the rod 31. This rod then no longer abuts against the leaf spring and can be moved towards the support 34, thus authorizing the closing of the cover 17.

Selon les besoins, il est possible d'augmenter le nombre de ressorts à lame pour une adaptation à un plus grand nombre de câbles, ou à un plus grand nombre d'éléments de jonction, selon une extension de type matriciel.Depending on requirements, it is possible to increase the number of leaf springs for adaptation to a larger number of cables, or to a larger number of junction elements, according to a matrix type extension.

Deux barreaux 51, 52 sont fixés aux extrémités du support de jonction de câbles. Chaque barreau est plié en forme de U, l'une des ailes du U étant fixée le long d'un côté transversal 4 ou 5 du cadre 1, l'autre aile du U supportant une plaque 53, 54. Sur chaque plaquette 53, 54 sont vissées transversalement trois tiges filetées 55 portant à une extrémité une manette 56, et à une autre extrémité un élément de mâchoire 57 mobile monté à pivote­ment sur cette extrémité.Two bars 51, 52 are fixed to the ends of the cable junction support. Each bar is folded in the shape of a U, one of the wings of the U being fixed along a transverse side 4 or 5 of the frame 1, the other wing of the U supporting a plate 53, 54. On each plate 53, 54 are screwed transversely three threaded rods 55 carrying at one end a handle 56, and at another end a movable jaw element 57 pivotally mounted on this end.

Sur les côtés transversaux 4, 5 du cadre 1, et en regard des éléments de mâchoire mobile 57, sont fixés des éléments de mâchoire fixes 58.Fixed jaw elements 58 are fixed on the transverse sides 4, 5 of the frame 1, and facing the movable jaw elements 57.

Sur la face du côté longitudinal 3 du cadre 1 qui est éloignée des cornières 6, 7, est fixé à plat et longitudinalement un barreau plat 61 en cuivre portant à chacune de ses extrémités une patte transversale 62, 63. Les pattes 62, 63 traversent chacune une lumière 64, 65 ménagée dans le côté 3 du cadre 1 et supportent chacune une vis 66, 67 fixée sur la patte.On the face of the longitudinal side 3 of the frame 1 which is distant from the angles 6, 7, is fixed flat and longitudinally a flat bar 61 made of copper carrying at each of its ends a transverse tab 62, 63. The tabs 62, 63 pass through each a light 64, 65 formed in the side 3 of the frame 1 and each support a screw 66, 67 fixed on the tab.

Un écrou à oreilles 68, 69 est attelé au cadre 1 au moyen d'une chaîne, à proximité de chaque patte 62, 63, pour coopérer avec les vis 66, 67.A wing nut 68, 69 is coupled to the frame 1 by means of a chain, near each lug 62, 63, to cooperate with the screws 66, 67.

Une griffe 59 connue en elle-même est fixée sur le côté longitudinal 2 du cadre 1, ou en un autre point compte tenu de la disposition du support sur le site, et permet de relier ce cadre à un conducteur de mise à la terre. Elle comporte une vis 60 pouvant être manoeuvrée en vue de pincer ce conducteur, et elle est reliée au barreau plat 61 par un barreau de même nature, non représenté sur les figures.A claw 59 known in itself is fixed to the longitudinal side 2 of the frame 1, or at another point taking into account the arrangement of the support on the site, and allows this frame to be connected to a grounding conductor. It comprises a screw 60 which can be operated in order to pinch this conductor, and it is connected to the flat bar 61 by a bar of the same kind, not shown in the figures.

Enfin, les deux côtés longitudinaux 2, 3 du cadre 1 comportent chacun deux trous 70 permettant la fixation du support de jonction de câbles sur une paroi. Cette fixation peut aussi être assurée grâce à deux trous débouchants 47 prévus sur les ailes 8 des deux cornières 6, 7 respectivement.Finally, the two longitudinal sides 2, 3 of the frame 1 each have two holes 70 allowing the fixing of the cable junction support on a wall. This fixing can also be ensured by two through holes 47 provided on the wings 8 of the two angles 6, 7 respectively.

Le support de jonction de câbles décrit ci-dessus peut être fixé sur une surface quelconque horizontale, verticale ou inclinée, par exemple sur un sol, un plafond ou un mur. Il peut notamment être fixé sur une portion de paroi inclinée d'un tunnel, dans une position représentée sur la figure 1, en vue de supporter les câbles d'alimen­tation d'un tunnelier. Un tel support sera prévu à chaque jonction entre deux tronçons de câbles.The cable joint support described above can be fixed to any horizontal, vertical or inclined surface, for example on a floor, a ceiling or a wall. It can in particular be fixed to an inclined wall portion of a tunnel, in a position shown in FIG. 1, in order to support the supply cables of a tunnel boring machine. Such a support will be provided at each junction between two sections of cables.

Sur la figure 6, trois câbles unipolaires 71, 72, 73 isolés représentent les différentes phases d'un réseau d'alimentation triphasé, et sont reliés à trois autres câbles 74, 75, 76. Chaque extrémité de câble est équipée d'une prise mobile femelle isolée 77, présentant un rebord annulaire 78 (figures 4 et 5). Deux prises mobiles femelles sont reliées entre elles par une pièce de jonction isolée 79 présentant deux extré­mités mâles. Par ailleurs, chaque prise mobile 77 est traversée par une tresse de mise à la terre 80.In FIG. 6, three single-pole cables 71, 72, 73 isolated represent the different phases of a three-phase supply network, and are connected to three other cables 74, 75, 76. Each cable end is equipped with a socket isolated female mobile 77, having an annular rim 78 (FIGS. 4 and 5). Two mobile female sockets are connected together by an insulated connecting piece 79 having two male ends. Furthermore, each movable socket 77 is crossed by a grounding braid 80.

Les jonctions entre les différents câbles étant effectuées, un opérateur dépose tout d'abord la jonction entre les câbles 73, 76 dans le fond arrondi 11 de l'évidement oblong 10 des cornières 6, 7. La longueur de cet évidement est inférieure au diamètre extérieur du rebord annulaire 78 des prises mobiles 77, et la distance entre les cornières est à peine plus importante que la distance séparant les deux rebords annulaires 78 d'une jonction. La jonction est ainsi immobilisée en translation et les deux prises 77 sont maintenues contre la pièce de jonction 79, même si une traction est appli­quée sur les câbles 73, 76.The junctions between the various cables being made, an operator firstly deposits the junction between the cables 73, 76 in the rounded bottom 11 of the oblong recess 10 of the angles 6, 7. The length of this recess is less than the diameter outside of the annular rim 78 of the mobile sockets 77, and the distance between the angles is hardly greater than the distance separating the two annular flanges 78 from a junction. The junction is thus immobilized in translation and the two sockets 77 are held against the junction piece 79, even if traction is applied to the cables 73, 76.

Ensuite, la jonction entre les câbles 72, 75 est déposée sur la précédente, les rebords 78 de l'une s'appuyant sur ceux de l'autre. Enfin la troisième jonction entre les câbles 71, 74 est déposée sur la précédente.Then, the junction between the cables 72, 75 is deposited on the previous one, the edges 78 of one resting on those of the other. Finally the third junction between the cables 71, 74 is deposited on the previous one.

Dans cette situation, les corps des prises mobiles 77 s'appuient sur les ressorts à lame situés au droit des deux tiges 31 et 33, tandis que les corps des pièces de jonction 79 s'appuient sur ceux situés au droit de la tige 32. L'opérateur fait alors pivoter le rabat 20 de façon que son rebord 21 vienne en appui sur la jonction réalisée entre les câbles 71 et 74, puis il rabat le couvercle 17 sur le rabat 20 en exerçant une pression afin d'amener les jonctions dans leur position de butée.In this situation, the bodies of the mobile sockets 77 are supported on the leaf springs located to the right of the two rods 31 and 33, while the bodies of the junction pieces 79 are supported on those located on the right of the rod 32. The operator then rotates the flap 20 so that its flange 21 comes to bear on the junction made between the cables 71 and 74, then it flaps the cover 17 on the flap 20 by applying pressure in order to bring the junctions into their stop position.

L'opérateur fait alors pivoter le loquet 24 afin d'introduire la seconde clé 23 dans le verrou 19, de la verrouiller en faisant tourner la clé volante 22, et de retirer cette dernière. La clé volante, unique pour une installation comprenant une pluralité de supports de jonction de câbles, est ainsi rendue disponible pour effectuer le verrouillage d'un support voisin ou des manoeuvres dans un poste en vue de l'alimentation électrique de l'installation. Il faut remarquer que le loquet 24 nepeut être amené au-dessus du verrou 19 que si le couvercle 17 a été complétement rabattu jusqu'à occuper une position perpendiculaire au plan du cadre 1.The operator then pivots the latch 24 in order to introduce the second key 23 into the lock 19, to lock it by rotating the flying key 22, and to remove the latter. The flying key, unique for an installation comprising a plurality of cable junction supports, is thus made available for locking out a neighboring support or maneuvers in a station for the power supply of the installation. It should be noted that the latch 24 can only be brought above the latch 19 if the cover 17 has been completely folded down until it occupies a position perpendicular to the plane of the frame 1.

On notera aussi que le mauvais positionnement ou l'absence de l'une seulement des prises mobiles 77 ou des pièces de jonction 79 provoque le blocage en translation d'une tige et interdit par conséquent la fermeture du couvercle. Au niveau de l'ensemble d'une installation comprenant plusieurs supports de jonction reliés les uns aux autres, on remarquera que le mauvais positionnement ou l'absence de l'un quelconque des nombreux éléments de jonction suffit à empêcher le verrouillage du support concerné et donc à interdire la libération de la clé qui conditionne la mise en tension de toute l'installation.It will also be noted that the incorrect positioning or the absence of only one of the mobile sockets 77 or of the junction pieces 79 causes the blocking in translation of a rod and consequently prohibits the closing of the cover. At the level of an entire installation comprising several junction supports connected to each other, it will be noted that the incorrect positioning or the absence of any one of the many junction elements is sufficient to prevent the locking of the support concerned and therefore to prohibit the release of the key which conditions the tensioning of the entire installation.

L'opérateur rapproche ensuite les éléments de mâchoire mobiles 57 des éléments de mâchoire fixes 58 pour enserrer chaque câble à proximité de la jonction. Les tresses de mise à la terre 80 des trois câbles d'un tronçon sont fixées par leur extrémité libre sur la vis 66 ou 67 montée sur le cadre 1, grâce à l'écrou à oreilles correspondant 68 ou 69. Par ailleurs, un conducteur de mise à la terre non isolé 81, tendu le long de la paroi sur laquelle est fixé le support, est amené dans la griffe de mise à la terre 80 et la vis 60 de celle-ci est manoeuvrée pour pincer le conducteur 81.The operator then brings the movable jaw elements 57 closer to the fixed jaw elements 58 to grip each cable near the junction. The earthing braids 80 of the three cables of a section are fixed by their free end to the screw 66 or 67 mounted on the frame 1, by means of the corresponding wing nut 68 or 69. Furthermore, a conductor of non-insulated grounding 81, stretched along the wall on which the support is fixed, is brought into the grounding claw 80 and the screw 60 thereof is operated to pinch the conductor 81.

On notera que dans le cas où les trois câbles 71, 72, 73 n'ont pas à être reliés aux trois autres câbles 74, 75, 76 mais constituent des "bouts morts", l'opérateur dispose, à la place des trois prises 77 des câbles 74, 75, 76, trois bouchons isolants femelles pourvus chacun d'un rebord annulaire.It will be noted that in the case where the three cables 71, 72, 73 do not have to be connected to the other three cables 74, 75, 76 but constitute "dead ends", the operator has, instead of the three sockets 77 of cables 74, 75, 76, three female insulating plugs each provided with an annular flange.

Le support représenté sur les figures 7 et 9 est une variante du support décrit ci-dessus et permet d'effectuer non seulement une jonction, mais en même temps une dérivation de câbles. Les pièces communes aux deux types de supports sont affectées des mêmes références.The support shown in Figures 7 and 9 is a variant of the support described above and allows not only a junction, but at the same time a cable diversion. The parts common to the two types of support are given the same references.

Entre les cornières 6, 7 du support de jonction et de dérivation, peuvent être montées de façon amovible soit la plaque pleine 16 du support de jonction (figure 1) dans le cas où seule une jonction est à réaliser, soit une plaque 100 (figures 7 et 9) dans le cas où une jonction et une dérivation sont à réaliser. La plaque 100 présente un évidement oblong 101 la traversant presque complétement et débouchant à une extrémité. Une cornière 102 en L présente deux ailes dont l'une est fixée sur la plaque 100 de façon à s'étendre le long de l'évide­ment oblong 101 et dont l'autre supporte une tige 103 montée de la même façon que les tiges 31 à 33 et disposée parallèlement à celles-ci. Le long de la tige 103 sont montés trois ressorts à lame 104 analogues aux ressorts à lame 38 à 40. La plaque 100 porte par ailleurs le rabat 20 utilisé dans le support de jonction de la figure 1.Between the angles 6, 7 of the junction and bypass support, can be removably mounted either the solid plate 16 of the junction support (Figure 1) in the case where only a junction is to be made, or a plate 100 (Figures 7 and 9) in the case where a junction and a bypass are to be made. The plate 100 has an oblong recess 101 passing through it almost completely and opening at one end. An L-shaped angle iron 102 has two wings, one of which is fixed to the plate 100 so as to extend along the oblong recess 101 and the other of which supports a rod 103 mounted in the same way as the rods 31 to 33 and arranged parallel thereto. Along the rod 103 are mounted three leaf springs 104 similar to the leaf springs 38 to 40. The plate 100 also carries the flap 20 used in the junction support of FIG. 1.

Un axe d'articulation 105, 106 est fixé sur les deux barreaux 51, 52, à proximité des plaquettes 53, 54 et parallèlement à celles-ci, grâce à deux pattes 107. Un support d'éléments de mâchoire 108, 109 en forme de U est monté de façon pivotante sur chaque axe d'articulation, grâce à deux pattes 110. Il comporte deux ailes dont l'une porte trois éléments de mâchoire fixes 111 et l'autre trois éléments de mâchoire mobiles 112 déplaçables au moyen d'une manette 113.A hinge pin 105, 106 is fixed on the two bars 51, 52, near the plates 53, 54 and parallel to these, by means of two legs 107. A support for jaw elements 108, 109 in the form of U is pivotally mounted on each articulation axis, by means of two legs 110. It comprises two wings, one of which carries three fixed jaw elements 111 and the other three movable jaw elements 112 displaceable by means of a joystick 113.

Chaque support d'éléments de mâchoire 108, 109 porte une patte de verrouillage 114 présentant un trou taraudé agencé pour coopérer avec une vis à oreilles 115 montée à rotation sur l'une des pattes 107, de façon à pouvoir être verrouillé dans une position perpendicu­laire au plan du cadre 1 (support 109, figure 7). Par ailleurs, le cadre 1 porte, sur chacun de ses côtés transversaux 4, 5, un clip 116, 117 agencé pour recevoir une tige de l'un des éléments de mâchoire mobiles 112 d'un support d'éléments de mâchoire 108, 109 lorsque celui-ci est replié contre le barreau adjacent 51, 52 (support 108, figure 7).Each jaw element support 108, 109 carries a locking tab 114 having a tapped hole arranged to cooperate with a wing screw 115 rotatably mounted on one of the legs 107, so that it can be locked in a perpendicular position in the plane of the frame 1 (support 109, FIG. 7). Furthermore, the frame 1 carries, on each of its transverse sides 4, 5, a clip 116, 117 arranged to receive a rod of one of the movable jaw elements 112 of a jaw element support 108, 109 when the latter is folded against the adjacent bar 51, 52 (support 108, FIG. 7).

Par ailleurs, le barreau plat 61 du support de la figure 7 porte une patte transversale supplémen­taire 118 équipée d'une vis 119 agencée pour recevoir un écrou à oreilles 120, ce qui permet de réunir les différentes tresses de mise à la terre 125 des prises de dérivation 126 au barreau plat 61 (figure 8).Furthermore, the flat bar 61 of the support of FIG. 7 carries an additional transverse tab 118 equipped with a screw 119 arranged to receive a wing nut 120, which makes it possible to bring together the different earthing braids 125 of the sockets bypass 126 to the flat bar 61 (Figure 8).

Chaque prise de dérivation 126 est une prise femelle et comporte un rebord annulaire 127. Elle est reliée aux deux prises de jonction 77 par une pièce de jonction-dérivation 128 présentant trois extrémités mâles.Each bypass socket 126 is a female socket and has an annular flange 127. It is connected to the two junction sockets 77 by a junction-bypass piece 128 having three male ends.

En vue du montage des câbles sur le support des figures 7 et 9, on réalise tout d'abord la jonction entre les câbles 71 à 73 et les câbles 74 à 76, et la liaison entre ceux-ci et les câbles de dérivation 131 à 133. La plaque 100 étant retirée et l'un des supports d'éléments de mâchoire 109 déployé, les câbles sont déposés successivement dans le support. La plaque 100 est ensuite glissée entre les cornières 6, 7, le rebord annulaire 127 des prises de dérivation coopérant avec la plaque 100 pour les retenir. Les prises de dérivation 126 prennent appui sur les ressorts à lame 104 de sorte que la tige 103 peut être enfoncée par le rabat 20. Le rabat 20 et le couvercle 17 sont alors rabattus en vue du verrouillage de la seconde clé 23 et de la libération de la clé volante 22. Les manettes 56 sont alors actionnées pour pincer les câbles de jonction 71 à 73 et 74 à 76 et les manettes 113 du support d'éléments de mâchoire 109 sont actionnées pour pincer les câbles de dérivation 131 à 133. Les mises à la terre des tresses de prises 80, 125 et du cadre 1 sont enfin réalisées.For the purpose of mounting the cables on the support of FIGS. 7 and 9, the junction between the cables 71 to 73 and the cables 74 to 76 is first made, and the connection between these and the branch cables 131 to 133. With the plate 100 removed and one of the jaw element supports 109 deployed, the cables are successively deposited in the support. The plate 100 is then slid between the angles 6, 7, the annular rim 127 of the bypass sockets cooperating with the plate 100 to retain them. The bypass sockets 126 are supported on the leaf springs 104 so that the rod 103 can be pushed in by the flap 20. The flap 20 and the cover 17 are then folded down in order to lock the second key 23 and release of the flying key 22. The levers 56 are then actuated to pinch the junction cables 71 to 73 and 74 to 76 and the levers 113 of the jaw element support 109 are actuated to pinch the branch cables 131 to 133. grounding of the braids of sockets 80, 125 and of the frame 1 are finally produced.

Pour le cas où l'opérateur a oublié de déployer le support d'éléments de mâchoire 109 avant de déposer les câbles dans le support de jonction et de dérivation, on peut prévoir que les axes d'articulation 105, 106 soient démontables et immobilisés en translation par des goupilles traversant les pattes 107. Ainsi, le démontage des axes permet de retirer le support d'élé­ments de mâchoires pour le disposer dans sa position de verrouillage.In the event that the operator has forgotten to deploy the jaw element support 109 before depositing the cables in the junction and branch support, provision may be made for the hinge pins 105, 106 to be removable and immobilized in translation by pins passing through the tabs 107. Thus, the disassembly of the shafts makes it possible to remove the support of jaw elements to place it in its locked position. .

Dans le cas du support de jonction et dérivation, on notera que le fait de prévoir le loquet 24 attelé à la plaque mobile 16 ou 100 garantit que l'opérateur n'oubliera pas de monter cette plaque.In the case of the junction and bypass support, it will be noted that the fact of providing the latch 24 coupled to the movable plate 16 or 100 guarantees that the operator will not forget to mount this plate.
