The craters receive a tool for extraction of a horizontal distribution comb and are delimited by bottom surfaces (48, 56) and lateral surfaces (50, 52, 58, 60). The bottom surfaces are retreated relative to a base surface (45), and the lateral surfaces are situated between the bottom surfaces and base surface.

Description

L'invention a trait aux appareils électriques adaptés à coopérer avec un peigne de répartition horizontale.The invention relates to electrical devices adapted to cooperate with a horizontal distribution comb.

On connaît déjà, notamment par le brevet français 2 751 162 , un tel appareil, qui est du type modulaire, c'est-à-dire à forme globalement parallélépipédique avec deux faces principales et des faces latérales s'étendant de l'une à l'autre des faces principales, en l'occurrence une face arrière, une face inférieure, une face avant et une face supérieure, laquelle présente des bornes pour un peigne présentant des dents régulièrement réparties suivant un pas correspondant à une largeur (distance entre les deux faces principales) normalisée pour ce type d'appareil, par exemple la largeur connue sous le nom de «module», qui est de l'ordre de 18 mm.We already know, in particular by the French patent 2,751,162 such an apparatus, which is of the modular type, that is to say of generally parallelepipedal shape with two main faces and side faces extending from one to the other of the main faces, in this case a rear face, a lower face, a front face and an upper face, which has terminals for a comb having regularly distributed teeth in a step corresponding to a width (distance between the two main faces) standardized for this type of device, for example the width known as the "module", which is of the order of 18 mm.

L'invention vise un tel appareil offrant une coopération simple et commode avec les peignes de répartition horizontale.The invention aims at such an apparatus offering a simple and convenient cooperation with the horizontal distribution combs.

Elle propose à cet effet un appareil électrique comportant une face présentant au moins un orifice donnant accès à une borne adaptée à recevoir une dent d'un peigne de répartition horizontale prévu pour être disposé vis-à-vis dudit appareil suivant une direction gauche - droite, caractérisé en ce que ladite face présente un renfoncement, situé à l'écart dudit orifice suivant ladite direction gauche - droite, adapté à recevoir un outil d'extraction dudit peigne, ledit renfoncement étant délimité au moins par une surface de fond et par une surface latérale, ladite surface de fond étant en retrait par rapport à une surface de base qui définit le plan général suivant lequel est orientée ladite face, ladite surface latérale étant située entre ladite surface de fond et ladite surface de base.It proposes for this purpose an electrical apparatus comprising a face having at least one opening giving access to a terminal adapted to receive a tooth of a horizontal distribution comb arranged to be arranged vis-à-vis said apparatus in a left-right direction , characterized in that said face has a recess, located away from said orifice in said left-right direction, adapted to receive a tool for extracting said comb, said recess being delimited at least by a bottom surface and by a lateral surface, said bottom surface being recessed with respect to a base surface which defines the general plane along which said face faces, said lateral surface being located between said bottom surface and said base surface.

Ainsi, même si l'effort d'extraction à exercer pour dégager le peigne de l'appareil est relativement important, ce qui est par exemple le cas si la borne auquel donne accès l'orifice est munie d'une pince à insertion enserrant fortement la dent, le renfoncement permet d'exercer cet effort dans de bonnes conditions avec un outil aussi courant qu'un tournevis à lame plate placé d'abord dans le renfoncement en regard d'une portion du peigne situé entre deux dents consécutives puis en faisant basculer cet outil pour écarter le peigne de l'appareil.Thus, even if the extraction force to be exerted to disengage the comb from the apparatus is relatively large, which is for example the case if the terminal to which the orifice gives access is provided with an insertion clamp strongly clamping the tooth, the recess makes it possible to exert this effort in good conditions with a tool as common as a screwdriver with flat blade placed first in the recess facing a portion of the comb located between two consecutive teeth and then making toggle this tool to move the comb away from the device.

Le disjoncteur modulaire 1 illustré sur la figure 1 a une forme globalement parallélépipédique.The modular circuit breaker 1 illustrated on the figure 1 has a generally parallelepipedal shape.

Il présente deux faces principale 2 et des faces latérales s'étendant de l'une à l'autre des faces principales 2, à savoir une face arrière 3, une face inférieure 4, une face avant 5 et une face supérieure 6.It has two main faces 2 and side faces extending from one to the other of the main faces 2, namely a rear face 3, a lower face 4, a front face 5 and an upper face 6.

La face arrière 3 présente une échancrure 7 pour le montage du disjoncteur 1 sur un rail normalisé à profil en Ω tel que le rail 30 illustré sur la figure 3.The rear face 3 has a notch 7 for mounting the circuit breaker 1 on a standard rail with a Ω profile such as the rail 30 shown in FIG. figure 3 .

La face inférieure 4 présente deux orifices d'accès à des bornes à vis (non visibles sur les dessins).The lower face 4 has two access ports to screw terminals (not visible in the drawings).

La face avant 5 présente, en position centrale, sur à peu près la moitié de sa longueur, un nez 8 présentant un levier de manoeuvre 9. Sous le nez 8 se trouvent deux orifices 10 et 11 permettant chacun d'accéder à la tête de la vis de l'une des bornes pour lesquelles un orifice d'accès est ménagé dans la face inférieure 4.The front face 5 has, in the central position, about half of its length, a nose 8 having an operating lever 9. Under the nose 8 are two orifices 10 and 11 each allowing access to the head of the the screw of one of the terminals for which an access orifice is formed in the lower face 4.

La face supérieure 6 présente deux orifices 12 et 13 donnant chacun accès à l'une des deux bornes à insertion 14 (figure 2) que comporte le disjoncteur 1.The upper face 6 has two orifices 12 and 13 each giving access to one of the two insertion terminals 14 ( figure 2 ) that circuit breaker 1 has.

Chaque borne 14 comporte une pince 15, un ressort 16 et un pavé de montage et de raccordement 17.Each terminal 14 comprises a clamp 15, a spring 16 and a mounting and connecting block 17.

La pince 15 est en matériau métallique bon conducteur de l'électricité, ici en cuivre étamé. Elle est en forme générale de lyre. Elle présente deux tronçons latéraux 20A et 20B se raccordant chacun par une extrémité à une extrémité respective d'un tronçon intermédiaire 20C globalement rectiligne. Les tronçons 20A et 20B sont symétriques, c'est-à-dire que l'un est l'image miroir de l'autre.The clamp 15 is made of metal material good conductor of electricity, here tinned copper. She is in the general shape of a lyre. It has two lateral sections 20A and 20B each connected at one end to a respective end of a generally rectilinear intermediate section 20C. The sections 20A and 20B are symmetrical, that is to say that one is the mirror image of the other.

A partir de leur extrémité opposée au tronçon intermédiaire 20C, c'est-à-dire à partir de leur extrémité distale, les tronçons 20A et 20B se rapprochent l'un de l'autre jusqu'à une zone d'inflexion 21 où ils sont les plus proches l'un de l'autre. Entre la zone d'inflexion 21 et le tronçon intermédiaire 20C, les tronçons 20A et 20B s'écartent l'un de l'autre, chaque tronçon ayant dans cette partie une conformation qui est ici relativement rectiligne.From their end opposite the intermediate section 20C, that is to say from their distal end, the sections 20A and 20B approach one another to an inflection zone 21 where they are closest to each other. Between the inflection zone 21 and the intermediate section 20C, the sections 20A and 20B deviate from each other, each section having in this part a conformation which is here relatively rectilinear.

Le ressort 16 est en matériau métallique présentant une bonne élasticité, ici en acier à ressort. Il a une forme générale en C. Il entoure étroitement la portion de la pince 15 comportant le tronçon intermédiaire 20C et la partie de chacun des tronçons 20A et 20B située entre le tronçon 20C et la zone d'inflexion 21, les extrémités du ressort 16 portant chacune contre la face externe de l'un des tronçon 20A et 20B au niveau de la zone d'inflexion 21.The spring 16 is made of metallic material having good elasticity, here in spring steel. It has a general shape C. It closely surrounds the portion of the clamp 15 comprising the intermediate portion 20C and the portion of each of the sections 20A and 20B located between the section 20C and the inflection zone 21, the ends of the spring 16 each bearing against the outer face of one of the sections 20A and 20B at the inflection zone 21.

Le pavé 17 est ici fait d'une seule pièce avec la pince 15, à laquelle il se raccorde par la tranche du tronçon intermédiaire 20C située à l'arrière sur la figure 2, au niveau d'un décrochement en léger débord identique à celui qu'on voit à l'avant sur la figure 2.The block 17 is here made in one piece with the clamp 15, to which it is connected by the edge of the intermediate section 20C located at the rear on the figure 2 , at the level of a setback in slight overhang identical to that seen in front on the figure 2 .

Le pavé 17 est plat et s'étend sur un plan parallèle à celui suivant lequel sont globalement orientés la pince 15 et le ressort 16. Le pavé 17 est disposé, par rapport au tronçon intermédiaire 20C, du côté opposé à celui où se trouvent les tronçons 20A et 20B, c'est-à-dire qu'il est disposé du côté qu'on voit en bas.The block 17 is flat and extends on a plane parallel to that along which are generally oriented the clamp 15 and the spring 16. The block 17 is disposed, relative to the intermediate section 20C, on the side opposite to that where the sections 20A and 20B, that is to say that it is arranged on the side seen below.

Le pavé 17 permet d'opérer la fixation mécanique de la borne 14 dans le disjoncteur 1 et le raccordement électrique de la borne 14 au circuit interne au disjoncteur 1.The pad 17 makes it possible to operate the mechanical fixing of the terminal 14 in the circuit-breaker 1 and the electrical connection of the terminal 14 to the internal circuit at the circuit-breaker 1.

Chaque borne 14 est disposée dans le disjoncteur 1 parallèlement aux faces principales 2 avec les extrémités distales des tronçons 20A et 20B situées à proximité de la face 6, l'espace entre les tronçons 20A et 20B étant aligné avec l'orifice 12 ou avec l'orifice 13.Each terminal 14 is disposed in the circuit breaker 1 parallel to the main faces 2 with the distal ends of the sections 20A and 20B located near the face 6, the space between the sections 20A and 20B being aligned with the orifice 12 or with the orifice 13.

Chacune des bornes 14 constitue une borne d'entrée pour l'un des pôles d'une source de courant alternatif, ici un pôle de neutre et un pôle de phase.Each of the terminals 14 constitutes an input terminal for one of the poles of an alternating current source, here a neutral pole and a phase pole.

Les bornes à vis dont les orifices d'accès sont situés dans la face inférieure 4 et dont la commande s'effectue par les orifices 10 et 11 de la face avant 2, sont quant à elles des bornes de sortie vers une portion d'une installation électrique protégée par le circuit interne du disjoncteur 1.The screw terminals whose access ports are located in the lower face 4 and controlled by the orifices 10 and 11 of the front face 2, are in turn output terminals to a portion of a electrical installation protected by the internal circuit of the circuit breaker 1.

L'alimentation du disjoncteur 1 est prévue pour être effectuée par deux peignes unipolaires de répartition horizontale conventionnels, portés respectivement au potentiel de neutre et au potentiel de phase, tels que les peignes 25A et 25B représentés sur les figures 3 à 5.The power supply of the circuit-breaker 1 is intended to be carried out by two conventional unipolar horizontal distribution combs, carried respectively at the neutral potential and the phase potential, such that the combs 25A and 25B shown on the FIG. Figures 3 to 5 .

Comme on le voit plus particulièrement sur les figures 4 et 5, les peignes 25A et 25B sont ici identiques. Ils comportent chacun une longrine 26 en forme de bande continue à partir de laquelle saillent une pluralité de dents 27, ici au nombre de treize.As we see more particularly on figures 4 and 5 , the combs 25A and 25B are here identical. They each comprise a sill 26 in the form of a continuous strip from which project a plurality of teeth 27, here thirteen in number.

La longrine 26 et les dents 27 sont faites d'une seule pièce dans une matière métallique bonne conductrice de l'électricité.The sill 26 and the teeth 27 are made of a single piece in a metal material good conductor of electricity.

La longrine 26 et les dents 27 sont ici orientées suivant un même plan. Les dents 27 sont régulièrement réparties, suivant un pas (entraxe entre deux dents consécutives) correspondant à la largeur d'un disjoncteur 1, c'est-à-dire la distance normalisée entre ses faces latérales 2 connue sous le nom de « module », qui est de l'ordre de 18 mm.The sill 26 and the teeth 27 are here oriented in the same plane. The teeth 27 are regularly distributed, following a step (center distance between two consecutive teeth) corresponding to the width of a circuit breaker 1, that is to say the normalized distance between its side faces 2 known as the "module", which is of the order of 18 mm.

Les peignes 25A et 25B comportent chacun, en outre de la longrine 26 et des dents 27, une enveloppe 28 en matière isolante à profil en U qui recouvre la longrine 26 de sa tranche jusqu'à la racine des dents 27.The combs 25A and 25B each comprise, in addition to the sill 26 and the teeth 27, a casing 28 of U-shaped insulating material which covers the sill 26 of its wafer to the root of the teeth 27.

Entre deux dents 27, la tranche de la longrine 26 est rectiligne et située au même niveau que la tranche de l'enveloppe 28 (voir sur la figure 4 la portion écorchée de l'enveloppe 28).Between two teeth 27, the edge of the sill 26 is rectilinear and located at the same level as the edge of the envelope 28 (see figure 4 the cut portion of the envelope 28).

Chaque borne 14 est prévue pour recevoir une dent telle que 27, par simple insertion dans la pince 15, avec bien entendu l'insertion qui se fait du côté de l'extrémité distale des tronçons 20A et 20B et le peigne dont fait partie la dent qui est orienté transversalement à la borne, c'est-à-dire suivant une direction gauche - droite.Each terminal 14 is provided to receive a tooth such as 27, by simple insertion into the clamp 15, with of course the insertion which is on the side of the distal end of the sections 20A and 20B and the comb of which the tooth is part. which is oriented transversely to the terminal, that is to say in a left-right direction.

La conformation de la borne 14 et de la dent 27 sont telles qu'après insertion la dent est fortement enserrée par la pince 15 au niveau des zones d'inflexion 21, de sorte qu'il s'établit un bon contact électrique.The conformation of the terminal 14 and the tooth 27 are such that after insertion the tooth is strongly gripped by the clamp 15 at the zones of inflection 21, so that a good electrical contact is established.

Les orifices 12 et 13 ménagés dans la face supérieure 6 du disjoncteur 1 permettent chacun à une dent 27 d'accéder à la borne à insertion 14 située juste en-dessous.The orifices 12 and 13 formed in the upper face 6 of the circuit breaker 1 each allow a tooth 27 to access the insertion terminal 14 located just below.

Les orifices 12 et 13 sont décalés dans le sens de la largeur du disjoncteur 1, l'orifice 12 étant ici situé du côté gauche et l'orifice 13 du côté droit. Ils sont également décalés dans le sens de la profondeur, l'orifice 12 étant situé en arrière de l'orifice 13.The orifices 12 and 13 are offset in the width direction of the circuit breaker 1, the orifice 12 being here on the left side and the orifice 13 on the right side. They are also offset in the direction of the depth, the orifice 12 being located behind the orifice 13.

Ainsi, lorsque plusieurs disjoncteurs 1 sont disposés côte à côte sur un même rail, par exemple sur le rail 30 comme montré sur la figure 3, les dents d'un même peigne, par exemple le peigne 25A, peuvent être introduites dans les orifices 12 des différents disjoncteurs 1 et les dents d'un autre peigne, par exemple le peigne 25B, peuvent être introduites dans les orifices 13 des différents disjoncteurs, le peigne 25B étant en avant du peigne 25A.Thus, when several circuit breakers 1 are arranged side by side on the same rail, for example on the rail 30 as shown in FIG. figure 3 the teeth of the same comb, for example the comb 25A, can be introduced into the orifices 12 of the different circuit-breakers 1 and the teeth of another comb, for example the comb 25B, can be introduced into the orifices 13 of the different circuit breakers, the comb 25B being in front of the comb 25A.

Ce qui précède vaut également si les appareils disposés côte à côte ne sont pas des disjoncteurs 1, mais d'autres appareils modulaires présentant une face supérieure similaire à la face 6, et en tous cas avec des orifices d'accès 12 et 13 disposés de la même manière.The above also applies if the devices arranged side by side are not circuit breakers 1, but other modular devices having a upper face similar to the face 6, and in any case with access ports 12 and 13 arranged in the same way.

Dans l'exemple illustré sur la figure 3, l'ensemble d'appareils montés sur le rail 30 comporte, en tant qu'appareil de tête de groupe, un interrupteur différentiel 31 et un ensemble de douze disjoncteurs 1 dont seuls les deux plus proches de l'interrupteur 31 ont été illustrés, pour ne pas surcharger le dessin.In the example shown on the figure 3 , the set of devices mounted on the rail 30 comprises, as a head unit group, a differential switch 31 and a set of twelve circuit breakers 1 of which only the two closest to the switch 31 have been illustrated, not to overload the drawing.

L'interrupteur différentiel 31 est du type décrit dans le brevet français 2751 162 .The differential switch 31 is of the type described in the French patent 2751 162 .

Sa largeur est le double de celle des disjoncteurs 1.Its width is twice that of circuit breakers 1.

Sa face supérieure 32 présente deux orifices 33 et 34 d'accès à des bornes à vis d'entrée et deux orifices 35 et 36 d'accès à des bornes de sortie.Its upper face 32 has two orifices 33 and 34 for access to input screw terminals and two orifices 35 and 36 for access to output terminals.

Les bornes d'entrée et les bornes de sortie de l'interrupteur 31 sont des bornes à vis. La face avant de l'interrupteur 31 présente des orifices 37 à 40 permettant chacun d'accéder à la vis de serrage de l'une des bornes d'entrée ou de sortie.The input terminals and the output terminals of the switch 31 are screw terminals. The front face of the switch 31 has orifices 37 to 40 each allowing access to the clamping screw of one of the input or output terminals.

La disposition des orifices 33 et 34 par rapport à la face arrière et à la face principale gauche de l'interrupteur 31 est identique à celle des orifices 12 et 13 par rapport aux faces correspondantes du disjoncteur 1, et de même pour les orifices 35 et 36 mais vis-à-vis de la face principale droite.The arrangement of the orifices 33 and 34 relative to the rear face and to the left main face of the switch 31 is identical to that of the orifices 12 and 13 with respect to the corresponding faces of the circuit breaker 1, and likewise for the orifices 35 and 36 but vis-à-vis the right main face.

Ainsi, la dent 27 extrême de gauche du peigne 25A peut être insérée dans l'orifice 35 et les autres dents 27 de ce peigne dans les orifices 12 des disjoncteurs 1 tandis que la dent extrême de gauche du peigne 25B peut être introduite dans l'orifice 36 et les autres dents de ce peigne dans les orifices 13 des disjoncteurs 1.Thus, the left extreme tooth 27 of the comb 25A can be inserted into the orifice 35 and the other teeth 27 of this comb into the orifices 12 of the circuit breakers 1 while the extreme left tooth of the comb 25B can be inserted into the orifice 36 and the other teeth of this comb in the orifices 13 of the circuit breakers 1.

Le serrage de la borne de sortie correspondant à l'orifice 35 s'effectue grâce à un tournevis introduit dans l'orifice 39 et le serrage de la borne correspondant à l'orifice 36 s'effectue grâce à un tournevis engagé dans l'orifice 40.Clamping of the output terminal corresponding to the orifice 35 is effected by means of a screwdriver inserted into the orifice 39 and the clamping of the terminal corresponding to the orifice 36 is effected by means of a screwdriver engaged in the orifice 40.

La cloison 41 qui est en saillie sur la face supérieure 32 de l'interrupteur 31 sert, comme expliqué dans le brevet français 2 751 162 , à éviter de disposer par inadvertance un même peigne à la fois dans une borne de sortie (orifice 35 ou 36) et dans une borne d'entrée (orifice 33 ou 34), ce qui court-circuiterait l'interrupteur 31.The partition 41 projecting from the upper face 32 of the switch 31 serves, as explained in FIG. French patent 2,751,162 to avoid inadvertently arranging the same comb both in an output terminal (port 35 or 36) and in an input terminal (port 33 or 34), which would bypass the switch 31.

L'alimentation des bornes d'entrée de l'interrupteur 31 s'effectue par des câbles (non représentés) reliés à un point de raccordement au réseau de distribution de l'électricité.The input terminals of the switch 31 are supplied by cables (not shown) connected to a point of connection to the electricity distribution network.

Dans le cas où l'on souhaite enlever les peignes 25A et 25B des appareils illustrés sur la figure 3, il faut desserrer les bornes de sortie de l'interrupteur 31 grâce à un tournevis y accédant par les orifices 39 et 40 puis exercer un effort d'extraction relativement important sur chacun des peignes 25A et 25B afin de dégager hors des bornes 14 les dents 27 restantes.In the case where it is desired to remove the combs 25A and 25B from the apparatuses illustrated in FIG. figure 3 , it is necessary to loosen the output terminals of the switch 31 with a screwdriver accessing through the orifices 39 and 40 and exert a relatively large extraction force on each of the combs 25A and 25B in order to clear the terminals 14 teeth 27 remaining.

On va maintenant décrire en détail les aménagements que présente la face supérieure 6 du disjoncteur 1 pour faciliter l'exercice d'un tel effort d'extraction.We will now describe in detail the arrangements that the upper face 6 of the circuit breaker 1 to facilitate the exercise of such an extraction effort.

La face supérieure 6 présente une surface de base 45 qui définit le plan général suivant lequel est orientée la face 6. La surface 45 est ici plate.The upper face 6 has a base surface 45 which defines the general plane along which is oriented the face 6. The surface 45 is here flat.

Chacun des orifices 12 et 13 à la forme d'une fente à contour rectangulaire dans le prolongement de laquelle se trouvent des surfaces 46 servant de butée d'enfoncement pour un peigne tel que 25A et 25B, les surfaces 46 étant disposées l'une et l'autre au même niveau, situé légèrement en dessous de la surface de base 45.Each of the orifices 12 and 13 in the form of a slot with a rectangular contour, the continuation of which are surfaces 46 serving as abutment stop for a comb such as 25A and 25B, the surfaces 46 being arranged one and the other at the same level, located slightly below the base surface 45.

Lorsque le peigne 25A ou 25B est mis en place, la venue d'une portion de la longrine 26 au contact des surfaces de butée 46 fait cesser la pénétration de la dent 27 dans l'orifice 12 ou 13.When the comb 25A or 25B is put in place, the coming of a portion of the sill 26 in contact with the abutment surfaces 46 stops the penetration of the tooth 27 into the orifice 12 or 13.

A gauche de l'orifice 13, la face 6 présente une cuvette 47 délimitée par une surface de fond 48, par une surface latérale avant 49, par une surface latérale gauche 50, par une surface latérale arrière 51 et par une surface latérale droite 52.To the left of the orifice 13, the face 6 has a bowl 47 delimited by a bottom surface 48, a front lateral surface 49, a left lateral surface 50, a rear lateral surface 51 and a straight lateral surface 52 .

La surface de fond 48 est rectangulaire et orientée parallèlement à la surface de base 45, la distance entre les surfaces 45 et 48, soit la profondeur de la cuvette 47 étant ici de l'ordre de 1,5 mm.The bottom surface 48 is rectangular and oriented parallel to the base surface 45, the distance between the surfaces 45 and 48, the depth of the bowl 47 being here of the order of 1.5 mm.

La surface latérale avant 49 est inclinée vers l'arrière et vers la surface de fond 48 alors que les surfaces latérales 50, 51 et 52 sont droites. L'écart entre la surface latérale gauche 50 et la surface latérale droite 52, soit la largeur de la cuvette 47, est de l'ordre de 6,5 mm.The front side surface 49 is inclined backwards and toward the bottom surface 48 while the side surfaces 50, 51 and 52 are straight. The gap between the left lateral surface 50 and the right lateral surface 52, ie the width of the bowl 47, is of the order of 6.5 mm.

Le sommet de la surface latérale avant 49 est disposé au niveau de l'extrémité avant de la face 6.The top of the front lateral surface 49 is disposed at the front end of the face 6.

La surface latérale arrière 51 est disposée en arrière de l'orifice 13 et en avant de l'orifice 12.The rear lateral surface 51 is disposed behind the orifice 13 and in front of the orifice 12.

Entre la surface 51 et l'orifice 12, la face 6 présente une dent 53 en saillie par rapport à la surface de base 45.Between the surface 51 and the orifice 12, the face 6 has a tooth 53 projecting from the base surface 45.

A droite de l'orifice 12, et en arrière de l'orifice 13, la face 6 présente une cuvette 55 ayant une surface de fond 56, une paroi latérale avant 57, une surface latérale gauche 58, une surface latérale arrière 59 et une surface latérale droite 60.To the right of the orifice 12, and behind the orifice 13, the face 6 has a bowl 55 having a bottom surface 56, a front lateral wall 57, a left lateral surface 58, a rear lateral surface 59 and a right side surface 60.

De même que la surface de fond 48 de la cuvette 47, la surface de fond 56 de la cuvette 55 est rectangulaire et orientée parallèlement à la surface de base 45, la distance entre les surfaces 45 et 56, soit la profondeur de la cuvette 55 étant la même que la distance entre les surfaces 45 et 48.Like the bottom surface 48 of the bowl 47, the bottom surface 56 of the bowl 55 is rectangular and oriented parallel to the base surface 45, the distance between the surfaces 45 and 56, the depth of the bowl 55. being the same as the distance between surfaces 45 and 48.

Toujours de même que pour la cuvette 47, la surface latérale avant 57 de la cuvette 55 est inclinée vers l'arrière et vers la surface de fond 56 alors que les surfaces latérales 58, 59 et 60 sont droites.Likewise for the bowl 47, the front side surface 57 of the bowl 55 is tilted back and toward the bottom surface 56 while the side surfaces 58, 59 and 60 are straight.

L'écart entre la surface latérale gauche 58 et la surface latérale droite 60, soit la largeur de la cuvette 55, est la même que celle de la cuvette 47.The gap between the left lateral surface 58 and the right lateral surface 60, ie the width of the bowl 55, is the same as that of the bowl 47.

En revanche, la surface de fond 56 présente une longueur (extension dans le sens avant - arrière) bien plus petite que celle de la surface de fond 48 de la cuvette 47.On the other hand, the bottom surface 56 has a length (extension in the front-back direction) much smaller than that of the bottom surface 48 of the bowl 47.

Les dimensions des cuvettes 47 et 55, et en particulier leur largeur et leur profondeur, sont prévues pour leur permettre de coopérer avec un tournevis à lame plate tel que le tournevis 65 montré sur les figures 4 et 5, dont la lame présente une largeur de 5,5 mm.The dimensions of the bowls 47 and 55, and in particular their width and depth, are provided to enable them to cooperate with a flat-blade screwdriver such as the screwdriver 65 shown on the drawings. figures 4 and 5 whose blade has a width of 5.5 mm.

Pour extraire le peigne 25B, qui est le premier à devoir être enlevé puisqu'il est disposé le plus en avant et masque donc la portion de la face 6 avec laquelle coopère le peigne 25A, on introduit la lame plate d'un tournevis tel que 65 dans la cuvette 47.To extract the comb 25B, which is the first to be removed since it is arranged furthest forward and therefore masks the portion of the face 6 with which the comb 25A cooperates, the flat blade of a screwdriver such as 65 in the bowl 47.

L'inclinaison de la surface latérale avant 49 et le fait que celle-ci soit située à l'avant de la face 6 facilite cette introduction, qui est poursuivie jusqu'à ce que le bout de la lame plate rencontre la surface latérale arrière 51, qui joue le rôle d'une surface d'arrêt permettant à l'opérateur de constater que la lame plate est bien en place.The inclination of the front lateral surface 49 and the fact that it is located at the front of the face 6 facilitates this introduction, which is continued until the tip of the flat blade meets the rear side surface 51 , which acts as a stop surface allowing the operator to see that the flat blade is in place.

L'extrémité de cette dernière se trouve alors en regard d'une portion de la longrine 26 située entre deux dents 27.The end of the latter is then facing a portion of the sill 26 located between two teeth 27.

Pour extraire le peigne 25B, on fait alors basculer le tournevis 65 autour de l'extrémité avant de la cuvette 47, et plus précisément autour de l'arête 66 située à la jonction entre la surface de base 45 et la surface latérale avant 49, dans le sens où la lame plate s'écarte de la face 6, c'est-à-dire dans le sens où l'opérateur abaisse le manche du tournevis 65, les dents 27 du peigne 25B étant ainsi extraites des différentes bornes que comportent les appareils avec lesquels coopère ce peigne, comme montré sur la figure 5.To extract the comb 25B, the screwdriver 65 is then tilted around the front end of the bowl 47, and more precisely around the edge 66 situated at the junction between the base surface 45 and the front lateral surface 49, in the sense that the flat blade deviates from the face 6, that is to say in the sense that the operator lowers the handle of the screwdriver 65, the teeth 27 of the comb 25B thus being extracted from the various terminals that comprise devices with which this comb cooperates, as shown on the figure 5 .

La dent 53 disposée en saillie entre la cuvette 47 et l'orifice 12 permet d'éviter à la lame du tournevis 65, au cours de la manoeuvre de basculement pour extraire le peigne 25B, de glisser vers l'arrière et de venir buter contre le peigne 25A.The tooth 53 disposed projecting between the bowl 47 and the orifice 12 makes it possible to prevent the blade of the screwdriver 65, during the tilting maneuver to extract the comb 25B, from sliding backwards and against the comb 25A.

Une fois le peigne 25B enlevé, il est possible d'accéder à la cuvette 55 pour extraire d'une façon similaire le peigne 25A, le tournevis tel que 65 pouvant basculer autour de l'arête 67 située à la jonction entre la surface 45 et la surface latérale avant 57.Once the comb 25B is removed, it is possible to access the bowl 55 to extract in a similar way the comb 25A, the screwdriver such as 65 being able to tilt around the edge 67 located at the junction between the surface 45 and the front lateral surface 57.

On notera que l'on a prévu, tant pour la cuvette 47 que pour la cuvette 55, de disposer leur extrémité antérieure aussi en avant que possible, soit tout à l'avant de la face 6 pour la cuvette 47 et à proximité immédiate de l'orifice 13 pour la cuvette 55, ce qui facilite l'introduction de la lame du tournevis tel que 65.It will be noted that provision has been made, for both the bowl 47 and the bowl 55, to arrange their anterior end as far forward as possible, or all the way to the front of the face 6 for the bowl 47 and in the immediate vicinity of the orifice 13 for the bowl 55, which facilitates the introduction of the blade of the screwdriver such as 65.

Dans une variante non représentée, l'orifice tel que 12, situé en arrière, est disposé du côté droit plutôt que du côté gauche et l'orifice tel que 13, situé en avant, du côté gauche plutôt que du côté droit, avec bien entendu la cuvette telle que 47 qui est alors située à droite de l'orifice tel que 13 et en avant de l'orifice tel que 12 tandis que la cuvette telle que 55 est située en arrière de l'orifice tel que 13 et à gauche de l'orifice tel que 12.In a variant not shown, the orifice such as 12, located behind, is arranged on the right side rather than the left side and the orifice such as 13, located in front of the left side rather than the right side, with good heard the bowl such as 47 which is then located to the right of the orifice such as 13 and in front of the orifice such as 12 while the bowl such as 55 is located behind the orifice such as 13 and left of the orifice such as 12.

Dans une autre variante non représentée, la face 6 de l'appareil 1 présente un seul orifice tel que 12 et 13 ou alors davantage que deux orifices.In another variant not shown, the face 6 of the device 1 has a single orifice such as 12 and 13 or more than two orifices.

Dans une autre variante non représentée, la cuvette telle que 47 ou 55 est remplacée par une cuvette conformée différemment, voire par un autre type de renfoncement délimité par une surface de fond telle que 48 ou 56 et par une seule surface latérale droite ou gauche telle que 50, 52, 58 ou 60.In another variant not shown, the bowl such as 47 or 55 is replaced by a bowl shaped differently, or by another type of recess defined by a bottom surface such as 48 or 56 and a single side surface right or left such than 50, 52, 58 or 60.

Dans une autre variante non représentée, les surfaces de butée d'enfoncement 46 sont conformées différemment, elles sont par exemple constituées directement par une portion de la surface de base 45, ou alors aucune surface de butée n'est prévue, l'arrêt de l'enfoncement des dents telles que 27 étant opéré directement par la borne telle que 14.In another variant not shown, the abutment abutment surfaces 46 are shaped differently, they are for example formed directly by a portion of the base surface 45, or no stop surface is provided, the stop of the depression of the teeth such that 27 is operated directly by the terminal such as 14.

Dans d'autres variantes non représentées la dent 53 est supprimée ou est alors remplacée par un autre type de protubérance, par exemple un téton ; la face telle que 6 appartient à un appareil modulaire autre qu'un disjoncteur simple, par exemple un coupe-circuit à fusible ou un disjoncteur différentiel constituant un appareil de tête de groupe dont la face supérieure est semblable à celle de l'interrupteur 31 mais avec la moitié de droite qui est conformée comme la face 6, ou alors la face telle que 6 appartient à un appareil qui n'est pas de type modulaire ; la borne à laquelle donne accès l'orifice tel que 12 ou 13 est une borne à insertion d'un autre type, par exemple telle que celles illustrées sur le brevet européen 0 434 964 ou alors il s'agit de bornes d'un type différent, par exemple à vis ; les bornes de sortie des appareils tels que 1 sont remplacées par des bornes d'un autre type, par exemple des bornes automatiques ou des bornes à connexion rapide, et de même d'ailleurs pour l'interrupteur différentiel 31 ou pour un autre appareil de tête de groupe ; et/ou les peignes employés sont remplacés par des peignes d'un autre type, par exemple un peigne dont la longrine n'est pas coplanaire avec les dents, notamment une longrine à profil en L.In other variants not shown the tooth 53 is removed or is then replaced by another type of protrusion, for example a stud; the face such as 6 belongs to a modular device other than a simple circuit breaker, for example a fused circuit breaker or a differential circuit breaker constituting a group head apparatus whose upper face is similar to that of the switch 31 but with the right half which is shaped as the face 6, or the face such as 6 belongs to an apparatus which is not of the modular type; the terminal to which access the orifice such as 12 or 13 is an insertion terminal of another type, for example such as those illustrated on the European patent 0 434 964 or else they are terminals of a different type, for example screwed; the output terminals of the apparatuses such as 1 are replaced by terminals of another type, for example automatic terminals or quick-connect terminals, and likewise for the differential switch 31 or for another device of group head; and / or the combs used are replaced by combs of another type, for example a comb whose sill is not coplanar with the teeth, in particular an L-shaped sill.

De nombreuses autres variantes sont possibles en fonction des circonstances, et on rappelle à cet égard que l'invention ne se limite pas aux exemples décrits et représentés.Many other variants are possible depending on the circumstances, and it is recalled in this regard that the invention is not limited to the examples described and shown.
