Abstract

Various types of connection may be set in place on the end regions. A connection with terminal includes a terminal with cage (29), the bottom of which has a projection (32) which fits into an orifice (28) made in the region (21) so as to immobilise the terminal (29). The terminal is held in this immobilised position by an insulating support (33) which jams up behind the bottom of the terminal (29), when set in place in a cavity made on the lateral face of the moulded case. These cavities (22) have runners for guiding the insulating part (33) so as to facilitate the setting into place of the connecting device. The cavities (22) can receive insulating supports for other modes of connection, in particular the support of a nut for fixing a lug or a rail, or the support for a connection emerging from the rear. <IMAGE>

Description

L'invention est relative à un dispositif de raccordement sur une plage terminale d'un appareil électrique à boîtier moulé, notamment d'un disjoncteur basse tension, ledit boîtier ayant sur l'une de ses faces latérales des cavités juxtaposées de logement des pièces de raccordement, chaque cavité étant associée à une plage perforée disposée à l'intérieur de cette cavité avec jeu pour permettre la mise en place sélectivement d'une borne de connexion entourant la plage, d'un écrou de fixation d'une cosse ou d'une barre de connexion et d'une barrette de raccordement arrière.The invention relates to a device for connecting to an end range of an electrical appliance with a molded case, in particular of a low voltage circuit breaker, said case having on one of its side faces juxtaposed cavities for housing parts of connection, each cavity being associated with a perforated pad disposed inside this cavity with clearance to allow the selective installation of a connection terminal surrounding the pad, of a nut for fixing a terminal or a connection bar and a rear connection bar.

Un dispositif du genre mentionné permet le raccordement à la plage terminale du disjoncteur d'un câble par l'intermédiaire d'une borne engagée sur la plage terminale. Il est également possible de raccorder une barre ou une cosse d'un câble par un boulon traversant la plage terminale perforée ou d'équiper cette plage d'une barrette de raccordement par l'arrière. L'adaptation du disjoncteur au type de conducteur raccordé nécessite la mise en place d'une borne ou d'un écrou sur la plage terminale et cette mise en place est généralement effectuée en atelier et en tous les cas avant le montage du disjoncteur. La borne est souvent fixée à la plage terminale ou au boîtier par une vis et cette mise en place nécessite donc un outil et un temps de montage non négligeable. Il est intéressant de pouvoir personnaliser l'appareil au dernier moment, c'est à dire lors du montage ou éventuellement après montage dans le coffret, en choisissant les pièces de raccordement adaptées au type de conducteur et en les montant sur les plages sans l'aide d'un outil et par un personnel non qualifié.A device of the kind mentioned allows connection to the terminal area of the circuit breaker of a cable by means of a terminal engaged on the terminal area. It is also possible to connect a bar or a cable lug with a bolt crossing the perforated terminal area or to equip this area with a connection strip from the rear. The adaptation of the circuit breaker to the type of conductor connected requires the installation of a terminal or a nut on the terminal range and this installation is generally carried out in the workshop and in any case before mounting the circuit breaker. The terminal is often fixed to the terminal shelf or to the housing by a screw and this installation therefore requires a tool and a significant assembly time. It is interesting to be able to personalize the device at the last moment, that is to say during assembly or possibly after assembly in the box, by choosing the connection parts suitable for the type of conductor and by mounting them on the pads without the using a tool and by unqualified personnel.

Il a déjà été proposé des bornes de raccordement pouvant être enfilées dans un logement du boîtier moulé, ce dernier étant fermé, pour les associer aux plages terminales. Ces bornes rainurées sur leurs faces latérales sont guidées lors de leur mise en place par des nervures du boîtier moulé, et l'ensemble est compliqué tout en ne permettant pas d'autres types de raccordement par des moyens simples. Le dispositif de raccordement selon l'invention est caractérisé en ce que chaque cavité est ouverte du côté de ladite face latérale pour une insertion parce côté des pièces de raccordement,sans ouverture du boîtier, que lesdites pièces comprennent une pièce métallique accolée à la plage, un moyen de serrage et un support isolant en matière plastique de maintien de ladite pièce métallique en position insérée dans la cavité, et que ledit support isolant présente une paire de rainures allongées s'étendant dans la direction d'insertion sur chacune des faces latérales du support et coopérant avec des nervures conjuguées ménagées sur les faces latérales de la cavité.It has already been proposed connection terminals that can be threaded into a housing of the molded housing, the latter being closed, to associate them with the terminal pads. These grooved terminals on their lateral faces are guided during their installation by ribs of the molded housing, and the assembly is complicated while not allowing other types of connection by simple means. The connection device according to the invention is characterized in that each cavity is open on the side of said side face for insertion because on the side of the connection pieces, without opening the housing, that said pieces comprise a metal piece attached to the track, a clamping means and an insulating plastic support for holding said metal part in the inserted position in the cavity, and that said insulating support has a pair of elongated grooves extending in the direction of insertion on each of the lateral faces of the support and cooperating with conjugate ribs formed on the lateral faces of the cavity.

Les cavités ouvertes sur la face latérale du disjoncteur facilitent l'accès aux plages terminales et la mise en place des pièces de raccordement sur ces plages. La pièce métallique de raccordement est portée et guidée par le support isolant en matière plastique qui seul coopère avec le boîtier moulé pour positionner les pièces de raccordement dans les cavités. Lors du raccordement,cette pièce métallique est solidarisée à la plage, elle même métallique par la vis de serrage sans exercer une contrainte sur le boîtier moulé.The open cavities on the side face of the circuit breaker facilitate access to the terminal areas and the installation of the connection pieces on these areas. The metallic connection piece is carried and guided by the insulating plastic support which alone cooperates with the molded housing to position the connection pieces in the cavities. During connection, this metal part is secured to the track, which is itself metallic by the clamping screw without exerting stress on the molded case.

Pour le raccordementd'un câble électrique, on insère dans la cavité une borne à cage de façon à introduire la plage terminale à l'intérieur de cette cage, au voisinage du fond de la borne. Ce fond présente sur sa face interne en regard de la plage, une saillie susceptible de s'emboîter dans l'oririce ménagé dans la plage, et d'immobiliser ainsi la borne dans la direction d'insertion. Le maintien de la borne dans cette position emboîtée sur la plage est obtenu par l'insertion d'un support isolant dans la cavité, ce support étant guidé par des glissières, pour venir se caler sous le fond de la borne et éviter ainsi tout déplacement en direction de sortie de la saillie de l'orifice de la plage. Ces glissières de guidage du support isolant sont constituées par une paire de rainures ménagées sur les faces latérales du support isolant, lesquelles rainures longitudinales coopèrent avec des nervures conjuguées,ménagées sur les parois de la cavité du boîtier moulé. Le support isolant est immobilisé en fin de course d'insertion par un système d'encliquetage, par exemple constitué par un bossage ménagé sur une face de la rainure qui s'encliquette dans un alvéole de la nervure. Tout autre système d'encliquetage est bien entendu utilisable et selon un développement important de l'invention, le support isolant est agencé en cage,de forme conjuguée à celle de la borne pour s'enfiler sur cette dernière et constituer un écran isolant. Lors de l'insertion de la borne dans la cavité, la vis de serrage, éventuellement desserrée, vient se loger dans une encoche prolongeant la cavité vers la face antérieure du boîtier moulé. Cette encoche permet le passage de l'outil de serrage de la vis à partir de la face antérieure du boîtier, et autorise la mise en place et le retrait de la borne avec une vis partiellement ou entièrement desserrée.For the connection of an electric cable, a cage terminal is inserted into the cavity so as to introduce the terminal area inside this cage, near the bottom of the terminal. This bottom has on its internal face opposite the beach, a projection capable of fitting into the orifice formed in the beach, and thus immobilizing the terminal in the direction of insertion. Maintaining the bollard in this nested position on the shelf is obtained by inserting an insulating support in the cavity, this support being guided by slides, to wedge under the bottom of the bollard and thus avoid any displacement towards the exit from the projection of the beach opening. These guide rails of the insulating support are constituted by a pair of grooves made on the lateral faces of the insulating support, which longitudinal grooves cooperate with conjugated ribs, formed on the walls of the cavity of the molded case. The insulating support is immobilized at the end of the insertion stroke by a latching system, for example constituted by a boss formed on one face of the groove which snaps into a cell in the rib. Any other snap-on system is of course usable and according to an important development of the invention, the insulating support is arranged in a cage, of shape combined with that of the terminal to slip on the latter and constitute an insulating screen. When the terminal is inserted into the cavity, the clamping screw, which may be loose, is housed in a notch extending the cavity towards the front face of the molded case. This notch allows the passage of the screw tightening tool from the front face of the housing, and allows the installation and removal of the terminal with a partially or fully loose screw.

Le raccordement d'une cosse ou d'une barre à la plage terminale, implique l'insertion d'un écrou à l'arrière de la plage. Dans l'écrou se visse la vis de serrage qui traverse la cosse et la plage par des orifices appropriés, et qui provoquent le serrage de la cosse sur cette plage.Selon la présente invention, l'écrou de forme polygonale, notamment rectangulaire, est placé dans un logement d'un support isolant, de forme analogue à celle du support isolant précité, permettant l'insertion dans la cavité, en étant guidé par les nervures ménagées sur les parois internes de la cavité. Ce support isolant est agencé pour amener l'écrou derrière la plage de contact où il est maintenu par ce support isolant qui s'encliquette dans la cavité. Lors du vissage de la vis de serrage, l'écrou est bien entendu solidarisé à la plage terminale sans exercer de contraintes directes sur le boîtier moulé. Il est avantageux d'équiper le support isolant de deux flasques latéraux venant encadrer la vis de serrage en position montée, pour constituer des écrans d'isolation additionnelle.The connection of a terminal or a bar to the terminal shelf involves the insertion of a nut at the rear of the shelf. In the nut is screwed the tightening screw which crosses the terminal and the range by suitable holes, and which cause the tightening of the terminal on this range. According to the present invention, the nut of polygonal shape, in particular rectangular, is placed in a housing of an insulating support, similar in shape to that of the aforementioned insulating support, allowing insertion into the cavity, being guided by the ribs formed on the internal walls of the cavity. This insulating support is arranged to bring the nut behind the contact pad where it is held by this insulating support which snaps into the cavity. When screwing the clamping screw, the nut is of course secured to the terminal area without exerting direct stress on the molded housing. It is advantageous to equip the insulating support with two side plates flanking the clamping screw in the mounted position, to form additional insulation screens.

On comprend que la mise en place de la borne ou de l'écrou peut être réalisée sur un appareil fixé à une platine ou dans un coffret, et que cette mise en place ou enlèvement ne nécessite aucune précaution ou dextérité particulière du cableur qui peut disposer d'une réserve de pièces de raccordement appropriées.It is understood that the installation of the terminal or the nut can be carried out on a device fixed to a plate or in a box, and that this installation or removal does not require any particular precaution or dexterity of the cableur which can have a reserve of suitable connection parts.

La fixation d'une barrette de raccordement par l'arrière à la plage terminale est effectuée d'une manière analogue en employant un support isolant ayant un manchon s'étendant perpendiculairement à la direction d'insertion du support isolant. La barrette est introduite dans son manchon, et l'ensemble barrette/ support isolant est inséré dans la cavité en étant guidé, de la manière décrite ci-dessus, par les glissières ménagées dans la cavité. En position d'encliquetage du support isolant dans la cavité, la face terminale de la barrette est au regard de la plage perforée à l'arrière de cette dernière, et il suffit de visser la vis de serrage pour solidariser cette barrette à la plage. L'isolation peut être parfaite en prolongeant le manchon au delà de la plage terminale, de manière a envelopper la vis de serrage. Pour éviter tout contact avec la vis de serrage, il est avantageux d'obturer l'extrémité libre du manchon par un capot par exemple constitué par une pièce encliquetée sur le support isolant et portant un capot articulé obturant en position rabattue cette extrémité du manchon et libérant cette ouverture pour la mise en place de la vis en position relevée.The fixing of a connection strip from the rear to the terminal area is carried out in a similar manner using an insulating support having a sleeve extending perpendicular to the direction of insertion of the insulating support. The bar is inserted into its sleeve, and the bar / insulating support assembly is inserted into the cavity while being guided, as described above, by the slides formed in the cavity. In the latching position of the insulating support in the cavity, the end face of the bar is opposite the perforated area at the rear of the latter, and it suffices to screw the clamping screw to secure this bar to the area. The insulation can be perfect by extending the sleeve beyond the terminal range, so as to wrap the clamping screw. To avoid contact with the clamping screw, it is advantageous to close the free end of the sleeve with a cover, for example constituted by a piece snapped onto the insulating support and carrying an articulated cover closing this end of the sleeve in the folded position and releasing this opening for the installation of the screw in the raised position.

Sur les figures, un appareil de coupure, en l'occurrence un disjoncteur basse tension quadripolaire, comporte un boîtier moulé 10, ayant une face antérieure 11 traversée par une manette de commande 12, et une face postérieure 13 de fixation sur une platine ou tout autre support approprié. Sur deux faces latérales 14,15 du boîtier moulé 10 en deux parties, une base 16 et un couvercle 17, sont disposés côte à côte des raccordements 18, respectivement d'entrée et de sortie du disjoncteur. Chaque pôle du disjoncteur comporte deux raccordements 18 reliés par un conducteur 19 dans lequel est insérée une paire de contacts 20, dont l'ouverture est commandée soit manuellement par la manette 12, soit automatiquement par des déclencheurs (non représentés), lors d'une surcharge ou d'un défaut. De tels disjoncteurs à boîtier moulé, par exemple décrits dans le brevet français n° 2.583.570, sont bien connus et ils peuvent bien entendu être du type tripolaire ou unipolaire.In the figures, a breaking device, in this case a low-voltage quadrupole circuit breaker, comprises a molded housing 10, having a front face 11 crossed by a control handle 12, and a rear face 13 for fixing on a plate or any other suitable support. On two side faces 14, 15 of the molded case 10 in two parts, a base 16 and a cover 17, are arranged side by side of the connections 18, respectively of input and output of the circuit breaker. Each pole of the circuit breaker has two connections 18 connected by a conductor 19 into which is inserted a pair of contacts 20, the opening of which is controlled either manually by the lever 12, or automatically by triggers (not shown), during a overload or fault. Such molded case circuit breakers, for example described in French Patent No. 2,583,570, are well known and they can of course be of the three-pole or unipolar type.

Les raccordements 18 sont tous identiques, et seul l'un d'entre eux est décrit en détail par la suite. Le conducteur 19 se termine par une plage terminale 21 débouchant sur la face latérale 14 du boîtier 10. La plage 21, sensiblement parallèle aux faces antérieure 11 et postérieure 13, est disposée dans une cavité 22, de forme générale rectangulaire, ménagée du côté de la face latérale 14. La cavité 22 a deux faces latérales 23 qui encadrent avec jeu la plage 21, une face antérieure 24 munie d'une encoche 25 débouchant du côté de la face antérieure 11 du boîtier 10, et un fond 26 ouvert vers la partie postérieure mais délimité par deux nervures latérales 27. La plage 21 espacée des faces latérales 23 est disposée au voisinage du fond 26, en ménageant un espace entre les nervures 27 et cette plage 21. La plage 21 est perforée en son centre, par un orifice 28 et elle peut recevoir différents dispositifs de raccordement, schématiquement illustrés sur la figure 1 et décrits en détail ci-dessous.The connections 18 are all identical, and only one of them is described in detail below. The conductor 19 ends with an end strip 21 opening onto the lateral face 14 of the housing 10. The strip 21, substantially parallel to the front 11 and rear 13 faces, is arranged in a cavity 22, of generally rectangular shape, formed on the side of the side face 14. The cavity 22 has two side faces 23 which playfully frame the track 21, a front face 24 provided with a notch 25 opening out on the side of the front face 11 of the housing 10, and a bottom 26 open towards the posterior part but delimited by two lateral ribs 27. The area 21 spaced from the lateral faces 23 is arranged in the vicinity of the bottom 26, leaving a space between the ribs 27 and this area 21. The area 21 is perforated in its center by a orifice 28 and it can receive different connection devices, schematically illustrated in FIG. 1 and described in detail below.

Les figures 3 à 5, montrent un dispositif de raccordement à borne équipant le premier pôle du disjoncteur de la figure 1, les autres pôles étant bien entendu équipés de la même manière. La borne 29 d'un type standard à cage pour le raccordement d'un câble, présente un fond 30, et du côté opposé une vis de serrage 31. Sur la face interne du fond 30, est ménagée une saillie 32 susceptible de s'emboîter dans l'orifice 28 de la plage 21. On voit que la borne 29 peut être insérée dans la cavité 22, en faisant pénétrer la plage 21 dans la borne 29 et la vis 31 dans l'encoche antérieure 25. Un déplacement perpendiculaire vers l'avant applique le fond 30 de la borne 29 contre la plage 21 et fait pénétrer la saillie 32 dans l'orifice 28 pour immobiliser la borne 29 dans le sens longitudinal d'insertion.Le maintien de la borne 29 dans cette position insérée dans la cavité 22 est réalisé par un support isolant 33 représenté à la figure 4, dont la base 34 comporte une paire de rainures 35 conjuguée des nervures 27 de la cavité 22. Le support isolant 33 est agencé en forme de cage 36 susceptible de s'emboi- ter sur la borne 29, en constituant un fourreau d'isolation. Le fond 37 de cette cage isolante 36 est agencé en plaque formant une cale venant lors de l'insertion du support isolant 33 dans la cavité 22, se glisser sous le fond 30 de la borne 29. Les rainures 35 et nervures 27 constituent des glissières de guidage du déplacement du support isolant 33, lequel présente un bossage 38 ménagé sur l'une des faces de la rainure 35 qui vient en position d'insertion du support 33 s'encliqueter dans un alvéole conjugué 39 pour maintenir en position insérée le support isolant 33. Sur la figure 3, on voit que le support isolant 33 empêche tout déplacement de la borne 29 vers le bas sur cette figure et maintient ainsi la saillie 32 emboîtée dans l'orifice 28. La borne 29 est prête à recevoir le câble qui est fixé de la manière usuelle par serrage de la vis 31, en solidarisant rigidement la borne 29 à la plage 21. La mise en place de la borne 29 et de son support isolant 33, ne nécessite aucun outil et peut être éffectuée, le boîtier moulé étant monté sur la platine ou fixé, de toute manière appropriée. L'enlèvement de la borne peut être effectué d'une manière inverse par un retrait du support isolant 33 et un désengagement de la borne 29 par un déplacement sortant la saillie 32 de l'orifice 28, et un retrait de la borne de la cavité 22.Figures 3 to 5 show a terminal connection device fitted to the first pole of the circuit breaker of Figure 1, the other poles being of course equipped in the same way. The terminal 29 of a standard type with cage for the connection of a cable, has a bottom 30, and on the opposite side a clamping screw 31. On the internal face of the bottom 30, is mé swung a projection 32 capable of fitting into the orifice 28 of the pad 21. It can be seen that the terminal 29 can be inserted into the cavity 22, making the pad 21 penetrate the terminal 29 and the screw 31 into the anterior notch 25. A perpendicular displacement towards the front applies the bottom 30 of the terminal 29 against the pad 21 and causes the projection 32 to penetrate the orifice 28 to immobilize the terminal 29 in the longitudinal direction of insertion. the terminal 29 in this position inserted into the cavity 22 is produced by an insulating support 33 shown in FIG. 4, the base 34 of which comprises a pair of grooves 35 conjugated with the ribs 27 of the cavity 22. The insulating support 33 is arranged in form of cage 36 capable of fitting onto terminal 29, constituting an insulation sheath. The bottom 37 of this insulating cage 36 is arranged in a plate forming a wedge coming when the insulating support 33 is inserted into the cavity 22, to slide under the bottom 30 of the terminal 29. The grooves 35 and ribs 27 constitute slides guiding the movement of the insulating support 33, which has a boss 38 formed on one of the faces of the groove 35 which comes into the insertion position of the support 33 snap into a conjugate socket 39 to keep the support in the inserted position insulator 33. In FIG. 3, it can be seen that the insulating support 33 prevents any displacement of the terminal 29 downwards in this figure and thus keeps the projection 32 fitted into the orifice 28. The terminal 29 is ready to receive the cable which is fixed in the usual manner by tightening the screw 31, rigidly securing the terminal 29 to the track 21. The installation of the terminal 29 and its insulating support 33, requires no tools and can be carried out, the housing molded being mounted on the plate or fixed in any suitable manner. The terminal can be removed in reverse by removing the insulating support 33 and disengaging the terminal 29 by moving the projection 32 out of the orifice 28, and removing the terminal from the cavity 22.

Les figures 6 à 8 illustrent un dispositif de raccordement d'une cosse 40 ou d'une barre perforée, du type représenté sur les pôles 3 et 4 de la figure 1. Ce dispositif de raccordement est constitué d'un écrou 41 de forme générale rectangulaire et d'un support isolant 42 ayant à sa base des rainures 35 susceptibles de coopérer avec les nervures 27 de la cavité 22. Le support isolant 42 présente une embase 43 de logement de l'écrou 41, lequel peut être placé sur cette embase 43 ou de préférence inséré dans un système de glissière 44 pour solidariser l'écrou 41 et le support isolant 42. L'ensemble écrou 41/support isolant 42 peut être inséré dans la cavité 22, en étant guidé par les glissières constituées par les rainures 35 et les nervures 27 pour amener l'écrou 41 sous la plage perforée 21 de la manière illustrée à la figure 6. En position encliquetée du support isolant 42, l'orifice 45 de l'écrou 41 est aligné avec l'orifice 28 de la plage 21, et le raccordement est réalisé en plaçant la cosse 40 sur la platine 21, et en vissant l'ensemble par la vis 46 qui traverse successivement la cosse 40, la platine 21 et l'écrou 41. La mise en place du dispositif de raccordement est particulièrement simple et la vis serrée 46 solidarise l'écrou 41 à la platine 21 sans exercer de contrainte sur le boîtier 10. Le remplacement de ce dispositif de raccordement à écrou 41 par un autre type de raccordement, s'effectue par un simple retrait du support 42 avec l'écrou 41, sans nécessiter d'outils particuliers. Sur le troisième pôle de la figure 1, et sur la figure 7, est représenté un support isolant 42 muni de deux flasques latéraux 47 venant encadrer en position insérée, la plage 21 et la vis 46 pour améliorer l'isolation électrique. Le quatrième pôle de la figure 1 est équipé d'un support 42 simplifié démuni de flasques 47 d'isolation.Figures 6 to 8 illustrate a device for connecting a terminal 40 or a perforated bar, of the type shown on poles 3 and 4 of Figure 1. This connection device consists of a nut 41 of general shape rectangular and an insulating support 42 having at its base grooves 35 capable of cooperating with the ribs 27 of the cavity 22. The insulating support 42 has a base 43 for housing the nut 41, which can be placed on this base 43 or preferably inserted into a slide system 44 to secure the nut 41 and the insulating support 42. The nut 41 / insulating support 42 assembly can be inserted into the cavity 22, being guided by the slides formed by the grooves 35 and the ribs 27 for bringing the nut 41 under the perforated area 21 as illustrated in FIG. 6. In the snap-in position of the insulating support 42, the orifice 45 of the nut 41 is aligned with the orifice 28 of range 21, e t the connection is made by placing the terminal 40 on the plate 21, and by screwing the assembly by the screw 46 which successively crosses the terminal 40, the plate 21 and the nut 41. The installation of the connection device is particularly simple and the tightened screw 46 secures the nut 41 to the plate 21 without exerting any stress on the housing 10. The replacement of this nut connection device 41 by another type of connection is effected by a simple removal of the support 42 with nut 41, without requiring special tools. On the third pole of Figure 1, and in Figure 7, there is shown an insulating support 42 provided with two lateral flanges 47 coming to frame in the inserted position, the track 21 and the screw 46 to improve the electrical insulation. The fourth pole of Figure 1 is equipped with a simplified support 42 without flanges 47 of insulation.

Les figures 9 à 12 et le pôle 2 de la figure 1 montrent la troisième variante du dispositif de raccordement permettant un départ par l'arrière. Ce dispositif de raccordement est constitué d'une barrette 48 et d'un support isolant 51. La barrette 48 ayant une section carrée est terminée d'un côté par une face 49 munie d'un orifice fileté 50 et du côté opposé, d'une plage de raccordement 52. Le support isolant 51 est agencé en forme de manchon 53 s'étendant perpendiculairement aux rainures 35 susceptibles de coopérer avec les nervures 27 pour constituer des glissières de guidage de la manière décrite ci-dessus. La barrette 48 est insérée dans le manchon 53 et l'ensemble est agencé de telle manière que lors de l'insertion du support isolant 51 dans la cavité 22, la face 49 vient se loger derrière la plage 21 en amenant l'orifice fileté 50 au droit de l'orifice 28 de la plage 21. Une vis de serrage 54 traversant la plage 21 et se vissant dans l'orifice fileté 50, solidarise la plage 21 et la barrette 48 pour constituer un raccordement par l'arrière. La barrette 48 comporte avantageusement une collerette 55 limitant l'engagement de la barrette 48 dans le support isolant 51 pour positionner correctement cette barrette par rapport à la plage 21. La section polygonale, en l'occurrence carrée, de la barrette 48 empêche toute rotation de cette dernière lors du vissage de la vis 54. Le support isolant 51 comporte avantageusement en prolongement du manchon 53 un écran 56 enveloppant la vis de serrage 54 en vue d'améliorer l'isolation du raccordement. Pour éviter toute possibilité de contact avec la vis 54, une pièce additionnelle 57 représentée à la figure 12 peut être encliquetée sur le support isolant 51 au droit de l'écran 56. Cette pièce 57 comporte un capot 58 susceptible d'être rabattu sur l'extrémité de l'écran 56 pour obstruer ce dernier et éviter tout contact avec la tête de la vis 54. Le capot 58 comporte un trou permettant le serrage ou desserrage de la vis avec une clef. Il peut être relevé pour permettre la mise en place de la vis qui se fait obligatoirement après la mise en place du support. La mise en place du dispositif de raccordement est à nouveau particulièrement simple et la barrette 48 s'étend vers la partie postérieure entre les nervures 27 en respectant les gabarits du disjoncteur.Figures 9 to 12 and pole 2 of Figure 1 show the third variant of the connection device allowing a departure from the rear. This connection device consists of a bar 48 and an insulating support 51. The bar 48 having a square section is terminated on one side by a face 49 provided with a threaded orifice 50 and on the opposite side, a connection pad 52. The insulating support 51 is arranged in the form of a sleeve 53 extending perpendicularly to the grooves 35 capable of cooperating with the ribs 27 to form guide slides in the manner described above. The bar 48 is inserted into the sleeve 53 and the assembly is arranged in such a way that during the insertion of the insulating support 51 into the cavity 22, the face 49 comes to lodge behind the track 21 by bringing the threaded orifice 50 to the right of the orifice 28 of the area 21. A clamping screw 54 crossing the area 21 and screwing into the threaded orifice 50, secures the area 21 and the bar 48 to form a connection from the rear. The bar 48 advantageously comprises a flange 55 limiting the engagement of the bar 48 in the insulating support 51 to correctly position this bar relative to the range 21. The polygonal section, in this case square, of the bar 48 prevents any rotation of the latter during the screwing of the screw 54. The insulating support 51 advantageously comprises, in extension of the sleeve 53, a screen 56 enveloping the clamping screw 54 in order to improve the insulation of the connection. To avoid any possibility of contact with the screw 54, an additional part 57 shown in FIG. 12 can be snapped onto the insulating support 51 in line with the screen 56. This part 57 comprises a cover 58 capable of being folded over the 'end of the screen 56 to obstruct it and avoid contact with the head of the screw 54. The cover 58 has a hole for tightening or loosening the screw with a key. It can be raised to allow the installation of the screw which must be done after the installation of the support. The installation of the connection device is again particularly simple. and the bar 48 extends towards the rear part between the ribs 27 while respecting the sizes of the circuit breaker.

La personnalisation du disjoncteur peut ainsi être éffectuée lors de son montage, les différents types de raccordement étant, soit systématiquement livrés avec le disjoncteur, soit fournis à la demande du monteur.Le changement du type de raccordement peut être effectué sur place sans démontage de l'appareil et une standardisation des raccordements de différents types d'appareil est concevable.The personalization of the circuit breaker can thus be carried out during its assembly, the different types of connection being either systematically delivered with the circuit breaker, or supplied at the request of the fitter. The change of the type of connection can be carried out on site without dismantling the he device and a standardization of the connections of different types of device is conceivable.

Aucun des dispositifs de raccordement selon l'invention n'est emprisonné dans le boîtier 10 et tout risque de détérioration de ce dernier, lors de la mise en place ou lors du serrage de la vis de fixation, est ainsi exclu. L'invention n'est bien entendu nullement limitée au mode de mise en oeuvre plus particulièrement décrit.None of the connection devices according to the invention is trapped in the housing 10 and any risk of deterioration of the latter, during the establishment or during the tightening of the fixing screw, is thus excluded. The invention is of course by no means limited to the mode of implementation more particularly described.
