Description

La présente invention est relative à un boîtier de raccordement de câbles ou conducteurs analogues réunis à un appareil ou un réseau d'utilisation quelconque, avec d'autres câbles ou fils de distribution, notamment aériens, véhiculant un courant électrique.The present invention relates to a connection box for cables or similar conductors joined to an appliance or a network of any use, with other cables or distribution wires, in particular overhead wires, carrying an electric current.

On connaît déjà de nombreuses réalisations de coffrets ou boîtiers de connexion pour le raccordement de câbles aériens d'alimentation avec des conducteurs de distribution. Parmi ces dispositifs connus, certains présentent l'inconvénient d'être sujets à une oxydation rapide, en raison de leur exposition aux intempéries. Notamment, ces coffrets, qui utilisent des boîtiers généralement métalliques, favorisent une condensation nuisible et surtout un raccordement des câbles effectué à l'air libre, avec des contacts manquant rapidement de fiablitité. De plus, ils mettent habituellement en oeuvre des vis de connexion en un matériau oxydable, ce que ne permet pas de garantir la continuité électrique au bout d'un certain temps, malgré la présence de graisses dans le boîtier qui assure cependant une meilleure étanchéité.Numerous embodiments of connection boxes or boxes are already known for the connection of overhead supply cables with distribution conductors. Among these known devices, some have the drawback of being subject to rapid oxidation, due to their exposure to the weather. In particular, these boxes, which use generally metal boxes, promote harmful condensation and above all a connection of the cables made in the open air, with contacts quickly lacking reliability. In addition, they usually use connection screws made of an oxidizable material, which does not guarantee electrical continuity after a certain time, despite the presence of grease in the housing which, however, provides a better seal.

Dans d'autres réalisations, à boîtiers en matière plastique, ces inconvénients sont en partie évités ; toutefois, les câbles sont raccordés par des vis à une réglette qui peut osciller au vent de telle sorte que les conducteurs éventuellement blessés lors de leur dénudage, se sectionnent rapidement au ras vis de fixation. Enfin, tout défaut constaté sur une ligne ou un câble de distribution, en particulier dans un réseau de télécommunication, ne peut être localisé qu'après avoir déconnecté les conducteurs de la réglette ou même par coupure des fils qui aboutissent à celle-ci pour les réunir à un appareil de test et de mesure, ce qui présente des inconvénients évidents et nécessite, après contrôle et réparation, un remontage complet des pièces du boîtier.In other embodiments, with plastic housings, these drawbacks are partly avoided; however, the cables are connected by screws to a strip which can oscillate in the wind so that the conductors, possibly injured during their stripping, quickly cut off flush with the fixing screws. Finally, any defect found on a distribution line or cable, in particular in a telecommunications network, can only be located after having disconnected the conductors from the strip or even by cutting the wires which lead to it for the join a test and measurement device, which has obvious drawbacks and requires, after inspection and repair, a complete reassembly of the parts of the housing.

La présente invention est relative à un boîtier de connexion qui présente sur les solutions actuellement connues des avantages remarquables, en permettant notamment le raccordement de tous types de câbles par l'intermédiaire d'un ensemble unique, immédiatement adaptable à n'importe quelle section des conducteurs à réunir, en particulier que les câbles d'alimentation et les conducteurs de distribution aient ou non le même diamètre. Notamment et selon l'invention, le branchement mutuel deux à deux de ces câbles et conducteurs est ici réalisé sans dénudage des fils, au moyen de vis spécialement adaptées, réalisant un contact électrique parfait sans blesser les conducteurs et un maintien permanent et efficace de ceux-ci en position dans le boîatier, de façon à éviter toute cassure ou rupture de ces conducteurs au ras de la connexion, même en cas d'oscillations dues au vent.The present invention relates to a connection box which has remarkable advantages over currently known solutions, in particular by allowing the connection of all types of cables by means of a single assembly, immediately adaptable to any section of the conductors to be joined, in particular whether the supply cables and the distribution conductors have the same diameter or not. In particular and according to the invention, the two-to-two mutual connection of these cables and conductors is here carried out without stripping the wires, by means of specially adapted screws, achieving perfect electrical contact without injuring the conductors and permanent and effective maintenance of those -this in position in the housing, so as to avoid any breakage or breakage of these conductors flush with the connection, even in the event of oscillations due to the wind.

Le boîtier selon l'invention présente également l'avantage de permettre une protection accrue vis-à-vis de l'oxydation des conducteurs par leur environnement, et également d'autoriser sans aucun démontage, une mesure simple par un appareil extérieur, pour la localisation et le repérage de défauts éventuels, le boîtier présentant enfin un encombrement réduit, étant simple à fabriquer et n'entraînant pour sa fabrication qu'un prix de revient limité.The housing according to the invention also has the advantage of allowing increased protection against oxidation of the conductors by their environment, and also of allowing without any disassembly, a simple measurement by an external device, for the location and identification of possible faults, the housing finally having a reduced size, being simple to manufacture and resulting in its manufacture only a limited cost price.

A cet effet, le boîtier de raccordement considéré, comportant un corps en un matériau plastique isolant électrique présentant, deux à deux opposées et situés par paire dans le prolongement l'un de l'autre, au moins quatre passages allongés, recevant respectivement l'extrêmité de câbles ou conducteurs à raccorder mutuellement, des vis de serrage étant montées dans le boîtier à l'intérieur de logements ouverts, s'étendant perpendiculairement à la direction des passages allongés et débouchant chacun dans un de ceux-ci, de telle sorte que ces vis immobilisent chacune l'extrêmité du câble ou conducteur engagé dans un passage, se caractérise en ce qu'il comporte une tourelle centrale pivotante montée à rotation autour d'un axe parallèle aux logements recevant les vis de serrage et qui supporte des moyens éclipsables propres à établir et interrompre une liaison électrique entre les câbles ou conducteurs engagés dans les passages allongés du corps.To this end, the connection box considered, comprising a body of an electrically insulating plastic material having, two by two opposite and located in pairs in the extension of one another, at least four elongated passages, receiving respectively the end of cables or conductors to be connected to each other, screws tightening being mounted in the housing inside open housings, extending perpendicular to the direction of the elongated passages and each opening into one of them, so that these screws each immobilize the end of the cable or conductor engaged in a passage, is characterized in that it comprises a pivoting central turret mounted for rotation about an axis parallel to the housings receiving the clamping screws and which supports eclipsable means capable of establishing and interrupting an electrical connection between the cables or conductors engaged in the elongated passages of the body.

Avantageusement, chaque passage allongé recevant un câble ou conducteur est ménagé dans un insert métallique, noyé à l'intérieur du corps en matière plastique, chaque insert étant isolé des autres, tandis que les moyens éclipsables de la tourelle centrale sont constitués par deux plots métalliques dont chacun est adapté à venir en contact ou à échapper aux extrêmités en regard de deux inserts correspondant à une paire de passages en regard et opposés dans le corps de boîtier.Advantageously, each elongated passage receiving a cable or conductor is formed in a metal insert, embedded inside the plastic body, each insert being isolated from the others, while the eclipsable means of the central turret are constituted by two metal studs each of which is suitable for coming into contact with or escaping from the opposite ends of two inserts corresponding to a pair of opposite and opposite passages in the housing body.

Selon une caractéristique particulière du boîtier selon l'invention, les deux plots métalliques sont constitués par des billes, de préférence à surface argentée, faisant saillie à l'extérieur d'alésages borgnes prévus dans la tourelle, diamétralement opposés l'un à l'autre par rapport à l'axe de rotation de celle-ci et soumis chacune à l'effet d'un ressort, monté entre le fond de l'alésage et la bille.According to a particular characteristic of the housing according to the invention, the two metal studs consist of balls, preferably with a silver surface, projecting outside the blind holes provided in the turret, diametrically opposite one to the other relative to the axis of rotation thereof and each subjected to the effect of a spring, mounted between the bottom of the bore and the ball.

Selon une autre caractéristique particulière, les inserts correspondant à une paire de passages en regard opposés comportent sur leur face dirigée vers la tourelle, un creux formant ensemble une cuvette propre à recevoir une des billes de la tourelle, faisant saillie sous l'effet du ressort monté dans son alésage borgne pour établir la liaison électrique entre les deux inserts.According to another particular characteristic, the inserts corresponding to a pair of opposite facing passages have on their face directed towards the turret, a hollow forming together a bowl suitable for receiving one of the balls of the turret, projecting under the effect of the spring mounted in its blind bore to establish the electrical connection between the two inserts.

Selon une autre caractéristique également, la tourelle centrale est réalisée en un matériau isolant et comporte un doigt inférieur axial engagé dans un puits prévu dans le boîtier et autour de l'axe duquel pivote la tourelle. De préférence, la partie infériuere du doigt est bloquée axialement au moyen d'une rondelle et d'un écrou ou d'un rivet.According to another characteristic also, the central turret is made of an insulating material and comprises an axial lower finger engaged in a well provided in the housing and around the axis of which the turret pivots. Preferably, the lower part of the finger is locked axially by means of a washer and a nut or a rivet.

Selon encore une autre caractéristiqe subsidiaire, la tourelle centrale comporte à sa partie supérieure opposée au doigt axial une rainure permettant de commander sa rotation, par exemple au moyen d'un tournevis ou analogue dont la pointe est engagée dans cette rainure. En outre et dans un mode de réalisation particulier de l'inventio, le boîtier plastique comporte dans son plan médian parallèle à la direction des paires de passages allongés deux à deux opposés, deux encoches d'arrêt pour les billes métalliques portées par la tourelle centrale et les recevant après une rotation de la tourelle faisant échapper ces billes aux cuvettes des inserts de façon à interrompre la continuité électrique entre les câbles ou conducteurs engagés dans ces passages.According to yet another subsidiary characteristic, the central turret has at its upper part opposite the axial finger a groove making it possible to control its rotation, for example by means of a screwdriver or the like, the tip of which is engaged in this groove. In addition and in a particular embodiment of the invention, the plastic housing comprises in its median plane parallel to the direction of the pairs of elongated passages two to two opposite, two stop notches for the metal balls carried by the central turret and receiving them after a rotation of the turret making these balls escape from the bowls of the inserts so as to interrupt the electrical continuity between the cables or conductors engaged in these passages.

De préférence, les cuvettes des inserts et les encoches d'arrêt des billes sont disposées dans deux plans perpendiculaires, le boîtier comportant deux paires de passages opposés.Preferably, the bowls of the inserts and the notches for stopping the balls are arranged in two perpendicular planes, the housing comprising two pairs of opposite passages.

Avantageusement, les vis de serrage montées dans les logements du boîtier sont réalisées en laiton, recouvert d'un alliage étain-plomb. Chaque tête de vis est cylindrique et présente une fente de manoeuvre prolongée axialement par une partie alésée formant cosse femelle de raccordement avec un embout terminal mâle monté à l'extrêmité d'un fil de liaison avec une borne d'un appareil de test ou de contrôle extérieur au boîtier. Chaque vis comporte par ailleurs à son extrêmité en contact avec le câble ou conducteur une partie coupante.Advantageously, the clamping screws mounted in the housing of the housing are made of brass, covered with a tin-lead alloy. Each screw head is cylindrical and has a maneuvering slot extended axially by a bored part forming a female terminal for connection with a male end fitting mounted at the end of a connecting wire with a terminal of a test or control outside the housing. Each screw also has a cutting part at its end in contact with the cable or conductor.

En outre et selon une caractéristique particulière, la partie coupante de chaque vis est disposée en regard d'une enclume ou analogue, faisant saillie selon l'axe du logement et disposée en regard dans chaque passage allongé.In addition and according to a particular characteristic, the cutting part of each screw is disposed opposite an anvil or the like, projecting along the axis of the housing and disposed opposite in each elongated passage.

Selon enfin une autre caractéristique, le boîtier isolant comporte, dans le prolongement de chaque logement recevant une vis de serrage, un rebord cylindrique saillant propre à éviter l'affleurement vers l'extérieur de la vis, ce rebord protégeant et isolant la connexion de l'embout terminal engagé dans la cosse femelle de la tête de vis montée dans le logement, en allongeant par ailleurs les lignes de fuite diélectriques ce qui diminue l'oxydation.Finally, according to another characteristic, the insulating housing comprises, in the extension of each housing receiving a clamping screw, a projecting cylindrical rim capable of preventing the outward flush of the screw, this rim protecting and insulating the connection of the 'end piece engaged in the female lug of the screw head mounted in the housing, also lengthening the dielectric creepage lines which reduces oxidation.

D'autres caractéristiques d'un boîtier de connexion pour câbles ou conducteurs électriques établi conformément à l'invention, apparaîtront encore à travers la description qui suit de divers exemples de réalisation, donnés ci-après à titre indicatif et non limitatif, en référence aux dessins annexés sur lesquels :

Comme on l'a représenté sur les Figures 1 et 2, le boîtier selon l'invention est constitué d'un bloc parallélépipédique 1, de préférence en matière plastique appropriée pour présenter des propriétés isolante vis-à-­ vis de l'électricité. A ce boîtier 1 aboutissent respectivement deux câbles d'alimentation 2 et 3 d'un côté et à l'opposé deux conducteurs de distribution 4 et 5. Chacun des câbles 2 et 3 d'une part, des conducteurs 4 et 5 d'autre part, est engagé à l'intérieur du boîtier 1 puis serré au moyen de vis 6 dans des passages convenables prévus dans des inserts métalliques 7 et 8 d'une part, 9 et 10 d'autre part, qui sont disposés par construction respectivement dans le prolongement l'un de l'autre de manière à permettre, par un raccordement adéquat, la liaison électrique ou au contraire l'interruption de cette liaison par suppression de ce raccordmeent, entre le câble 2 et le conducteur 4 grâce aux inserts 7 et 8, et entre le câble 3 et le conducteur 5 par les inserts 9 et 10 deux à deux en regard.As shown in Figures 1 and 2, the housing according to the invention consists of a parallelepiped block 1, preferably made of plastic suitable for having insulating properties vis-à-vis screw electricity. To this box 1 lead respectively two supply cables 2 and 3 on one side and on the opposite side two distribution conductors 4 and 5. Each of the cables 2 and 3 on the one hand, conductors 4 and 5 on the other on the other hand, is engaged inside the housing 1 and then tightened by means of screws 6 in suitable passages provided in metal inserts 7 and 8 on the one hand, 9 and 10 on the other hand, which are arranged by construction respectively in the extension of one another so as to allow, by an adequate connection, the electrical connection or on the contrary the interruption of this connection by removal of this connection, between the cable 2 and the conductor 4 thanks to the inserts 7 and 8, and between the cable 3 and the conductor 5 by the inserts 9 and 10 two by two opposite.

A cet effet et selon l'invention, le boîtier 1 est muni d'une tourelle centrale 11, propre à pivoter sur elle-même autour de son axe situé sensiblement dans le plan médian du boîtier perpendiculairement à la direction des inserts 7 à 10, cette tourelle 11 supportant deux billes métalliques 12 et 13, de préférence à surface argentée, qui, dans la position de la tourelle illustrée sur la Figure 1 assurent ainsi la liaison électrique entre les inserts métalliques avec lesquels elles sont en contact ou au contraire interrompent cette liaison dans la position vue sur la Figure 2 où ces billes se placent entre ces inserts mais sans contact avec ceux-ci. Dans cette dernière position, les vis de serrage 6, grâce à une conformation adéquate de leur têtes formant cosses de liaison, peuvent être connectées à un appareil de test ou de mesure extérieur 14, par l'intermédiaire de fils de liaison 15 réunis deux par deux à des bornes homologues de cet appareil.To this end and according to the invention, the housing 1 is provided with a central turret 11, capable of pivoting on itself around its axis situated substantially in the median plane of the housing perpendicular to the direction of the inserts 7 to 10, this turret 11 supporting two metal balls 12 and 13, preferably with a silver surface, which, in the position of the turret illustrated in FIG. 1, thus ensure the electrical connection between the metal inserts with which they are in contact or on the contrary interrupt this link in the position seen in Figure 2 where these balls are placed between these inserts but without contact with them. In this latter position, the clamping screws 6, by virtue of an adequate conformation of their heads forming connecting lugs, can be connected to an external test or measurement device 14, by means of connecting wires 15 joined together by two to homologous terminals of this device.

Les Figures 3 et 4 illustrent avec plus de détail un mode de réalisation particulier du boîtier de connexion considéré.Figures 3 and 4 illustrate in more detail a particular embodiment of the connection box considered.

On retrouve sur cette Figure le bloc isolant 1 en matière plastique, à l'intérieur duquel sont noyés, notamment lors de la fabrication par moulage du boîtier, les inserts métalliques 7 à 10. Ceux-ci se présentent sous la forme de blocs de métal coducteur, par exemple en laiton ou aluminium, et comportent chacun un passage allongé, respectivement 16, 17, 18 et 19 (Figure 4). Chaque passage est fermé vers l'intérieur du boîtier dans l'insert métallique correspondant et ouvert à l'opposé vers les faces extérieures du boîtier 1, de façon à permettre l'engagement dans chacun de ces passages de l'extrêmité des câbles ou conducteurs 2 à 5 à raccorder entre eux. Ainsi, dans l'exemple considéré, les câbles 2 et 3 s'engagent dans les passages 16 et 17 des inserts 7 et 8, et les conducteurs 4 et 5 dans les passages 18 et 19 des inserts 9 et 10. A l'entrée de chaque passage, le boîtier 1 comporte avantageusement une partie évasée 20 pour faciliter l'engagement de chaque câble ou conducteur dans l'insert correspondant.We find in this Figure the insulating block 1 of plastic, inside which are embedded, in particular during the manufacture by molding of the housing, the metal inserts 7 to 10. These are in the form of metal blocks encoder, for example brass or aluminum, and each have an elongated passage, respectively 16, 17, 18 and 19 (Figure 4). Each passage is closed towards the inside of the box in the corresponding metal insert and open opposite towards the outside faces of the box 1, so as to allow the engagement in each of these passages of the ends of the cables or conductors. 2 to 5 to be connected together. Thus, in the example considered, the cables 2 and 3 engage in the passages 16 and 17 of the inserts 7 and 8, and the conductors 4 and 5 in the passages 18 and 19 of the inserts 9 and 10. At the entrance of each passage, the housing 1 advantageously comprises a flared part 20 to facilitate the engagement of each cable or conductor in the corresponding insert.

L'immobilisation des câbles ou conducteurs 2 à 5 dans leurs inserts 7 à 10 est réalisé au moyen des vis 6 dont chacune comporte une tête 21 munie axialement d'une partie creuse 22 formant cosse femelle de raccordement avec un embout terminal 44 prévu à l'extrêmité de chaque fils de liaison 15 raccordant le boîtier à l'appareil de test 14. En outre, est prévue dans la tête 21 une fente transversale 23 permettant de commander par un tournevis ou analogue (non représenté) la rotation de la vis 6. Celle-ci présente sous la tête 21, une partie filetée 24 coopérant avec un trou taraudé 25 prévu dans l'insert correspondant pour permettre à l'extrêmité inférieure 26 de la vis 6 de faire saillie progressive dans le passage allongé prévu dans cet insert en venant serrer le câble ou conducteur monté dans celui-ci. De préférence, la partie inférieure 26 de la vis comporte un bord coupant 27 qui permet de sectionner légèrement, sans blessure, la gaine 28 du câble ou conducteur et d'atteindre l'âme métallique 29 de celui-ci, en assurant la continuité électrique avec la vis 6. En regard de la vis 6 dans le passage correspon­dant est prévue une enclume 30 en relief dans l'intérieur du passage et qui permet par coopération avec la partie coupante 27 d'assurer une liaison électrique sûre, quellle que soient les dimensions relatives du câble ou conducteur vis-à-vis du diamètre interne du passage qui le reçoit.The immobilization of cables or conductors 2 to 5 in their inserts 7 to 10 is carried out by means of screws 6 each of which comprises a head 21 provided axially with a hollow part 22 forming a female terminal for connection with a terminal end piece 44 provided at the 'end of each connecting wire 15 connecting the housing to the test apparatus 14. In addition, is provided in the head 21 a transverse slot 23 for controlling by rotation with a screwdriver or the like (not shown) the rotation of the screw 6 This has under the head 21, a threaded part 24 cooperating with a threaded hole 25 provided in the corresponding insert to allow the lower end 26 of the screw 6 to protrude progressively in the elongated passage provided in this insert. by tightening the cable or conductor mounted therein. Preferably, the part lower 26 of the screw has a cutting edge 27 which makes it possible to slightly cut, without injury, the sheath 28 of the cable or conductor and to reach the metal core 29 of the latter, ensuring electrical continuity with the screw 6. Opposite the screw 6 in the corresponding passage is an anvil 30 in relief in the interior of the passage and which, by cooperation with the cutting part 27, ensures a secure electrical connection, whatever the relative dimensions of the cable or conductor vis-à-vis the internal diameter of the passage which receives it.

Les inserts 7 à 10 placés deux à deux en regard à l'intérieur du boîtier 1, comportent par ailleurs à leurs extrêmités se faisant face des empreintes en creux telles qu'elles forment entre les deux inserts une cuvette 31, dirigée vers la tourelle 11 et propre à recevoir, pour une orientation relative convenable de celle-ci autour de son axe une des billes 12 et 13, l'autre bille étant simultanément engagée dans la cuvette correspondante réalisée sur les deux autres inserts. Dans l'exemple considéré, où les inserts sont au nombre de quatre, les cuvettes 31 sont au nombre de deux, respectivement délimitées par les empreintes des inserts 7 et 9 d'une part, 8 et 10 d'autre part. Dans cette position, les billes 12 et 13 assurent donc la continuité électrique des inserts correspondants et, à travers ceux-ci et les vis de serrage 6, entre le câble 2 et le conducteur 4 d'une part, le câble 3 et le conducteur 5 d'autre part.The inserts 7 to 10 placed two by two facing the inside of the housing 1, furthermore have, at their ends facing each other, hollow recesses such that they form between the two inserts a bowl 31, directed towards the turret 11 and suitable for receiving, for a suitable relative orientation of the latter around its axis, one of the balls 12 and 13, the other ball being simultaneously engaged in the corresponding cup produced on the two other inserts. In the example considered, where the inserts are four in number, the bowls 31 are two in number, respectively delimited by the imprints of the inserts 7 and 9 on the one hand, 8 and 10 on the other hand. In this position, the balls 12 and 13 therefore ensure the electrical continuity of the corresponding inserts and, through these and the clamping screws 6, between the cable 2 and the conductor 4 on the one hand, the cable 3 and the conductor 5 on the other hand.

En revanche, pour une position où la tourelle 11 est tournée de 90 par rapport à la précédente, les billes 12 et 13 viennent s'engager dans deux encoches 32, prévues dans le corps du boîtier 1 en dehors des inserts 7 à 10, en interrompant dès lors les liaisons électriques précédentes.On the other hand, for a position where the turret 11 is turned 90 relative to the previous one, the balls 12 and 13 engage in two notches 32, provided in the body of the housing 1 outside the inserts 7 to 10, in therefore interrupting the previous electrical connections.

Les billes 12 et 13 sont montées dans la tourelle 11 à l'extrêmité inférieure d'alésages borgnes 33 prévus dans celle-ci, en étant soumises à l'effet d'un ressort 34 logé dans cet alésage, et qui permet aux billes de faire légèrement saillie à la base de la tourelle et de s'engager à la manière de clips dans les cuvettes 31 ou les encoches 32 selon la position de cette tourelle, notammen grâce à l'appui réalisé par ces ressorts en évitant que les billes ne sortent involontairement de ces cuvettes ou encoches.The balls 12 and 13 are mounted in the turret 11 at the lower end of blind holes 33 provided in the latter, being subjected to the effect of a spring 34 housed in this bore, and which allows the balls to protrude slightly at the base of the turret and to engage in the manner of clips in the bowls 31 or the notches 32 depending on the position of this turret, in particular thanks to the support produced by these springs, preventing the balls from involuntarily emerging from these bowls or notches.

La tourelle 11 comporte un doigt axial 35 pénétrant dans un puits 36 prévu au centre du boîtier 1 et débouchant sous celui-ci dans un chambrage 36 recevant une rondelle d'arrêt 38 bloquée contre le fond du chambrage par un écrou ou un rivet 39 immobilisant axialement la tourelle par son doigt 35. A sa partie opposée la tourelle 11 comporte une fente transversale 40, permettant à un outil extérieur (non représenté) de la manoeuvrer en rota­tion autour de son axe pour établir ou au contraire inter­rompre par les billes 12 et 13 la liaison électrique entre les inserts et les câbles et conducteurs.The turret 11 comprises an axial finger 35 penetrating into a well 36 provided in the center of the housing 1 and emerging under the latter in a recess 36 receiving a stop washer 38 blocked against the bottom of the recess by a nut or a rivet 39 immobilizing axially the turret by its finger 35. At its opposite part the turret 11 has a transverse slot 40, allowing an external tool (not shown) to maneuver it in rotation about its axis to establish or on the contrary interrupt by the balls 12 and 13 the electrical connection between the inserts and the cables and conductors.

Le corps du boîtier 1 comporte enfin pour le montage des vis 6 de serrage des câbles ou conducteurs 2 à 5, des longements 41 débordant largement de la tête 21 des vis et délimités chacun par un rebord 42 de manière à éviter tout contact électrique non souhaité avec ces vis. Ces logements 42 peuvent recevoir, lorsque les billes 12 et 13 sont dans les encoches 32 interrompent la liaison électrique entre les inserts, des plots 43, prolongés par des embouts 44 propres à s'engager dans les cosses femelles 22 des têtes 21 des vis 6, en réunissant ainsi aux câbles 2 et 3 d'un côté, aux conducteurs 4 et 5 de l'autre, l'appareil de test et de mesure 14 (Figure 5).The body of the housing 1 finally comprises, for the mounting of the screws 6 for tightening the cables or conductors 2 to 5, lengths 41 extending well beyond the head 21 of the screws and each delimited by a flange 42 so as to avoid any unwanted electrical contact with these screws. These housings 42 can receive, when the balls 12 and 13 are in the notches 32 interrupt the electrical connection between the inserts, studs 43, extended by end pieces 44 suitable for engaging in the female lugs 22 of the heads 21 of the screws 6 , thus joining cables 2 and 3 on one side, conductors 4 and 5 on the other, the test and measurement device 14 (Figure 5).

On réalise ainsi un boîtier de raccordement de conception très simple et présentant une remarquable fiabilité de fonctionnement, l'agencement de la tourelle centrale rotative qui selon sa position assure ou interrompt la connexion électrique permettant par ailleurs sans aucun démontage de procéder à un contrôle ou test des circuits réunis par le boîtier.There is thus produced a connection box of very simple design and having remarkable operating reliability, the arrangement of the rotary central turret which, depending on its position, ensures or interrupts the electrical connection allowing, moreover, without any disassembly, to carry out a control or test of the circuits joined by the housing.

Bien entendu, il doit être considéré que l'invention ne se limite pas à l'exemple de réalisation plus spécialement décrit et représenté donne seulement à titre indicatif ; elle en embrasse au contraire toutes les variantes.Of course, it should be considered that the invention is not limited to the embodiment more specially described and shown gives only for information; on the contrary, it embraces all its variants.
