Description

La présente invention concerne un bloc auxiliaire notamment de signalisation de l'état de disjoncteurs.The present invention relates to an auxiliary unit in particular for signaling the state of circuit breakers.

On connaît des blocs auxiliaires accouplés latéralement à un ensemble de disjoncteurs accolés par leur faces latérales, lesdits blocs étant utilisés par exemple pour contrôler l'état des disjoncteurs ou bien détecter la présence d'un défaut dans leur fonctionnement (surintensité, courts-circuits etc...). Ces blocs auxiliaires sont constitués, sous leur forme la plus générale, par un boîtier monobloc comportant d'une part, des contacts dits auxiliaires commandés par le mécanisme des disjoncteurs et reliés électriquement par des plots de raccordement prévus dans l'un des côtés du boîtier, à un tableau de signalisation, tandis que le côté opposé du boîtier présente un évidement destiné à autoriser le passage d'une ou de plusieurs dents d'un peigne de distribution assurant l'alimentation des disjoncteurs. Or, le branchement du peigne s'effectue en amont ou en aval des disjoncteurs selon les pays dans lesquels ces disjoncteurs sont destinés à être utilisés. Il en résulte qu'il est nécessaire de disposer de deux types de blocs auxiliaires permettant respectivement un montage du peigne en aval ou en amont des disjoncteurs.Auxiliary blocks are known which are coupled laterally to a set of circuit breakers joined by their lateral faces, said blocks being used for example to control the state of the circuit breakers or else to detect the presence of a fault in their operation (overcurrent, short circuits etc.). ...). These auxiliary blocks are constituted, in their most general form, by a monobloc box comprising on the one hand, so-called auxiliary contacts controlled by the mechanism of the circuit breakers and electrically connected by connection pads provided in one of the sides of the box. , to a signaling panel, while the opposite side of the housing has a recess intended to allow the passage of one or more teeth of a distribution comb ensuring the supply of circuit breakers. However, the comb is connected upstream or downstream of the circuit breakers according to the countries in which these circuit breakers are intended to be used. It follows that it is necessary to have two types of auxiliary blocks respectively allowing a mounting of the comb downstream or upstream of the circuit breakers.

La présente invention résout ce problème et propose un bloc auxiliaire notamment de signalisation de l'état de disjoncteurs, de conception simple, et pouvant être utilisé aussi bien pour un montage en amont ou en aval du peigne dans le but d'une standardisation accrue.The present invention solves this problem and proposes an auxiliary block, in particular for signaling the state of circuit breakers, of simple design, and which can be used both for mounting upstream or downstream of the comb for the purpose of increased standardization.

A cet effet, la présente invention a pour objet un bloc auxiliaire notamment de signalisation de l'état d'un disjoncteur, destiné à être accouplé et accolé latéralement à un bloc disjoncteur, ledit bloc auxiliaire étant formé par un boîtier renfermant des contacts auxiliaires commandés mécaniquement par le mécanisme du bloc disjoncteur, et reliés électriquement à des bornes de connexion agencées sur l'un des côtés du boîtier, tandis que le côté opposé du boîtier comporte un évidement destiné à permettre le passage d'une ou de plusieurs dents d'un peigne de distribution assurant l'alimentation électrique du bloc disjoncteur, ce bloc étant caractérisé en ce que le boîtier est équipé de deux parties distinctes comprenant une partie principale fixée au bloc disjoncteur et renfermant les contacts auxiliaires, et une deuxième partie de raccordement comportant des plots de raccordement des contacts auxiliaires et ledit évidement, et en ce que la deuxième partie est montée orientable sur la partie principale suivant deux positions différentes permettant respectivement le montage du peigne de distribution en amont ou en aval du bloc disjoncteur.To this end, the subject of the present invention is an auxiliary block, in particular for signaling the state of a circuit breaker, intended to be coupled and attached laterally to a circuit breaker block, said auxiliary block being formed by a housing containing controlled auxiliary contacts. mechanically by the mechanism of the circuit breaker block, and electrically connected to connection terminals arranged on one of the sides of the housing, while the opposite side of the housing has a recess intended to allow the passage of one or more teeth of a distribution comb ensuring the electrical supply of the circuit breaker block, this block being characterized in that the housing is equipped with two separate parts comprising a main part fixed to the circuit breaker block and containing the auxiliary contacts, and a second connection part comprising connection pads of the auxiliary contacts and said recess, and in that the second he part is mounted orientable on the main part in two different positions allowing respectively the mounting of the distribution comb upstream or downstream of the circuit breaker block.

On voit déjà que grâce à l'invention, il suffit d'orienter la partie de raccordement de manière que l'évidement ménagé dans ladite partie se trouve en regard du peigne.It can already be seen that, thanks to the invention, it suffices to orient the connection part so that the recess in said part is located opposite the comb.

Selon une réalisation particulière de l'invention, la partie de raccordement est montée tournante autour d'un axe sensiblement perpendiculaire au plan des dents du peigne, le passage de l'une des positions précitées à l'autre s'effectuant par une rotation de 180° de la partie de raccordement autour dudit axe.According to a particular embodiment of the invention, the connection part is rotatably mounted about an axis substantially perpendicular to the plane of the teeth of the comb, the passage from one of the above positions to the other being effected by a rotation of 180 ° of the connection part around said axis.

Selon une caractéristique particulière, la partie de raccordement comporte un logement destiné à recevoir la partie inférieure de forme conjuguée de la partie principale, autour de laquelle la partie de raccordement est montée tournante.According to a particular characteristic, the connection part comprises a housing intended to receive the lower part of conjugate shape of the main part, around which the connection part is mounted to rotate.

Selon une autre caractéristique, la partie principale et la partie de raccordement comportent des moyens pour limiter la course de rotation de la partie de raccordement à 180°.According to another characteristic, the main part and the connection part comprise means for limiting the rotational stroke of the connection part to 180 °.

Selon une variante de réalisation, la partie principale comporte une rainure dans laquelle est introduite et fixée une partie de forme conjuguée de la partie de raccordement.According to an alternative embodiment, the main part has a groove into which is introduced and fixed a part of conjugate shape of the connecting part.

Selon une caractéristique particulière, les plots de raccordement sont reliés aux contacts auxiliaires précités par l'intermédiaire de fils conducteurs traversant deux orifices prévus respectivement dans la partie de raccordement et la partie principale.According to a particular characteristic, the connection pads are connected to the aforementioned auxiliary contacts by means of conductive wires passing through two orifices provided respectively in the connection part and the main part.

Selon une variante de réalisation, les plots sont reliés aux contacts auxiliaires par l'intermédiaire de contacts frottants prévus de part et d'autre de la partie principale coopérant avec des éléments conducteurs reliés aux plots précités.According to an alternative embodiment, the studs are connected to the auxiliary contacts by means of friction contacts provided on either side of the main part cooperating with conductive elements connected to the aforementioned studs.

Avantageusement, le bloc comporte trois plots de raccordement et trois contacts auxiliaires formant un inverseur.Advantageously, the block comprises three connection pads and three auxiliary contacts forming a reverser.

Selon une autre caractéristique, la partie principale comprend une partie de forme sensiblement parallèlépipédique et deux bras s'étendant perpendiculairement aux faces latérales de ladite partie parallèlépipédique, lesdits bras prenant appui respectivement sur une partie en forme de C ou une partie opposée étagée logeant les plots de raccordement de la partie de raccordement.According to another characteristic, the main part comprises a part of substantially parallelepiped shape and two arms extending perpendicular to the lateral faces of said parallelepiped part, said arms bearing respectively on a C-shaped part or an opposite stepped part housing the studs of the connection part.

Sur la figure 1, on voit un bloc auxiliaire B accolé par l'une des ses faces latérales à un bloc disjoncteur 1 formé par plusieurs disjoncteurs 1a, 1b, 1c accouplés latéralement et alimentés par un peigne de distribution 7 raccordé à un jeu de barres triphasé (non représenté). Ce bloc auxiliaire B est du type des blocs utilisés pour contrôler l'état d'ouverture ou de fermeture des disjoncteurs ou bien détecter un défaut tel qu'une surintensité ou bien un court-circuit.In FIG. 1, an auxiliary block B is seen attached by one of its lateral faces to a circuit breaker block 1 formed by several circuit breakers 1a, 1b, 1c coupled laterally and supplied by a distribution comb 7 connected to a busbar three-phase (not shown). This auxiliary block B is of the type of blocks used to control the opening or closing state of the circuit breakers or else detect a fault such as an overcurrent or a short circuit.

En se reportant aux figures 2 à 6 qui décrivent deux réalisations différentes de l'invention, on voit que le bloc auxiliaire B est formé par un boîtier 2 constitué de deux parties distinctes appelées respectivement partie principale 8 et partie de raccordement 9. La partie principale 8 comprend une partie sensiblement parallèlépipédique 22 et deux bras 23, 24 s'étendant perpendiculairement aux parois latérales de cette partie 22. La partie de raccordement 9 est formée d'une partie latérale sensiblement en forme de C 25, d'une partie latérale opposée étagée 26 et d'une partie de liaison 27 de ces deux dernières parties 25, 26. Les parois internes de ces parties latérales 25, 26 et de liaison 27 forment un logement 11 pour la partie inférieure 12 de la partie principale précitée 8 dont les deux bras 23, 24 viennent en appui respectivement sur les faces supérieures des parties latérales précitées 25, 26. La partie principale 8 comprend trois contacts dits auxiliaires 3 formant un inverseur, ces trois contacts 3a, 3b, 3c étant reliés d'une part mécaniquement au mécanisme des disjoncteurs auxquels le bloc auxiliaire B est associé, et d'autre part, par l'intermédiaire de fils conducteurs 13, 30 respectivement à trois plots de raccordement 4 placés à l'intérieur de la partie latérale étagée précitée 26 de la partie de raccordement 9, lesdits plots 4 étant destinés à être reliés électriquement à un tableau de signalisation (non représenté) relié par exemple à un pupitre de commande. La partie latérale en forme de C 25 de la partie de raccordement 9, opposée à la partie latérale étagée 26, comporte un évidement 10 destiné à permettre le passage des dents 7a du peigne de distribution 7.Referring to Figures 2 to 6 which describe two different embodiments of the invention, we see that the auxiliary unit B is formed by a housing 2 consisting of two separate parts called respectively main part 8 and connection part 9. The main part 8 comprises a substantially parallelepiped part 22 and two arms 23, 24 extending perpendicular to the side walls of this part 22. The connection part 9 is formed from a substantially C-shaped side part 25, from an opposite side part stepped 26 and a connecting part 27 of these last two parts 25, 26. The internal walls of these side parts 25, 26 and connecting 27 form a housing 11 for the lower part 12 of the above-mentioned main part 8, the two arms 23, 24 come to bear respectively on the upper faces of the abovementioned lateral parts 25, 26. The main part 8 comprises three so-called auxiliary contacts 3 forming an inverter, these three contacts 3a, 3b, 3c being connected on the one hand mechanically to the mechanism of the circuit breakers to which the auxiliary unit B is associated, and on the other hand, via conductive wires 13, 30 respectively with three connection pads 4 placed inside the above-mentioned stepped side part 26 of the connection part 9, said pads 4 being intended to be electrically connected to a signaling panel (not shown) connected for example to a control console. The C-shaped lateral part 25 of the connection part 9, opposite to the stepped lateral part 26, has a recess 10 intended to allow the passage of the teeth 7a of the distribution comb 7.

Selon ces réalisations de l'invention, la partie de raccordement 9 est montée tournante par des moyens appropriés, autour de la partie principale 8, et autour d'un axe X sensiblement perpendiculaire au plan P des dents 7a du peigne précité 7.According to these embodiments of the invention, the connection part 9 is rotatably mounted by appropriate means, around the main part 8, and around an axis X substantially perpendicular to the plane P of the teeth 7a of the above-mentioned comb 7.

En se reportant plus particulièrement aux figures 2 et 3, on voit que selon une première forme de réalisation particulière de l'invention, les contacts auxiliaires précités 3 sont reliés aux plots de raccordement 4 par des fils conducteurs 13 traversant deux orifices 15, 14 prévus respectivement dans la paroi inférieure de la partie principale 8 et la paroi supérieure de la partie de liaison 27 de la partie de raccordement 9.With particular reference to FIGS. 2 and 3, it can be seen that according to a first particular embodiment of the invention, the aforementioned auxiliary contacts 3 are connected to the connection pads 4 by conductive wires 13 passing through two orifices 15, 14 provided respectively in the lower wall of the main part 8 and the upper wall of the connecting part 27 of the connecting part 9.

La partie principale 8 comporte sur l'un de ses côtés, un ergot 39 destiné à venir en contact contre deux butées opposées 30, 31 formées dans la partie de raccordement 9, lors de la rotation de la partie de raccordement 9 autour de la partie principale 8. Ces deux butées 30, 31 permettent de limiter la course de rotation de la partie de raccordement 9 à 180° afin d'éviter le cisaillement des fils conducteurs 13.The main part 8 has on one of its sides, a lug 39 intended to come into contact against two opposite stops 30, 31 formed in the connection part 9, during the rotation of the connection part 9 around the part main 8. These two stops 30, 31 make it possible to limit the rotational stroke of the connection part 9 to 180 ° in order to avoid shearing of the conductive wires 13.

Selon une autre forme de réalisation décrite sur les figures 5 et 6, les trois plots de raccordements précités 4 sont reliés aux trois contacts auxiliaires 3 par trois contacts dits frottants. Trois plages de contact 16 à 18 et 19 à 21 sont ainsi prévues de part et d'autre de la partie principale 8. Les trois plages de contact 16 à 18 et 19 à 21 situées de chaque côté sont reliées respectivement par trois fils conducteurs 31a, 31b, 31c et 31d, 31e, 31f, aux trois contacts auxiliaires 3a, 3b, 3c.According to another embodiment described in Figures 5 and 6, the three aforementioned connection pads 4 are connected to the three auxiliary contacts 3 by three so-called friction contacts. Three contact pads 16 to 18 and 19 to 21 are thus provided on either side of the main part 8. The three contact pads 16 to 18 and 19 to 21 located on each side are connected respectively by three conductive wires 31a , 31b, 31c and 31d, 31e, 31f, to the three auxiliary contacts 3a, 3b, 3c.

En se reportant aux figures 7 et 8, on voit une autre réalisation de l'invention suivant laquelle la partie de raccordement 29 est montée sur la partie principale 28 de manière à pouvoir être retournée et permettre ainsi un montage du peigne 7 en amont ou en aval des disjoncteurs. Selon cette réalisation, la partie principale 28 comprend une partie parallèlépipédique 22 et deux bras 23, 24, la partie parallèlépipédique 22 comportant une rainure 28a dans laquelle est fixée, par des moyens appropriés, une partie dite de liaison 29a reliant la partie en forme de C 25 et la partie étagée 26 d'une partie de raccordement 29 telle que celle décrite précédemment. On notera que le raccordement des plots 4 aux contacts auxiliaires 3, bien que non illustré sur ces figures, pourra être réalisé par exemple au moyen de fils conducteurs traversant deux orifices prévus dans la partie principale et la partie de raccordement, ou bien au moyen de contacts frottants tels que ceux décrits précédemment.Referring to Figures 7 and 8, we see another embodiment of the invention according to which the connection part 29 is mounted on the main part 28 so that it can be turned over and thus allow mounting of the comb 7 upstream or in downstream of the circuit breakers. According to this embodiment, the main part 28 comprises a part parallelepipedic 22 and two arms 23, 24, the parallelepipedic part 22 comprising a groove 28a in which is fixed, by appropriate means, a so-called connecting part 29a connecting the C-shaped part 25 and the stepped part 26 of a part connection 29 such as that described above. It will be noted that the connection of the pads 4 to the auxiliary contacts 3, although not illustrated in these figures, could be carried out for example by means of conductive wires passing through two orifices provided in the main part and the connection part, or else by means of rubbing contacts such as those described above.

On décrira ci-après brièvement le montage de la partie de raccordement (8, 28) sur la partie principale (9, 29) pour les différentes réalisations de l'invention.The mounting of the connection part (8, 28) will be briefly described below on the main part (9, 29) for the various embodiments of the invention.

Selon la réalisation décrite sur les figures 2 et 3, le passage de la partie de raccordement 9 d'une position permettant le montage du peigne 7 en amont telle qu'illustrée sur les figures 2 et 3, à une position permettant le montage du peigne 7 en aval des disjoncteurs (figure 4), s'effectue en opérant une rotation relative de la partie de raccordement 9 par rapport à la partie principale 8 de 180°.According to the embodiment described in Figures 2 and 3, the passage of the connecting part 9 from a position allowing the mounting of the comb 7 upstream as illustrated in Figures 2 and 3, to a position allowing the mounting of the comb 7 downstream of the circuit breakers (FIG. 4), is effected by operating a relative rotation of the connection part 9 with respect to the main part 8 by 180 °.

Ce mouvement amène l'ergot 39 en appui contre le second élément de butée 31 prévu sur la partie de raccordement 9. Ainsi, le mouvement opposé, de passage de la position de montage à l'aval à la position de montage en amont, s'effectuera par une nouvelle rotation de 180° de la partie de raccordement 9 dans un sens opposé au précédent dans le but, comme déjà indiqué précédemment, de ne pas cisailler les fils conducteurs 13.This movement brings the lug 39 in abutment against the second stop element 31 provided on the connection part 9. Thus, the opposite movement, from the mounting position downstream to the upstream mounting position, s 'will carry out by a new rotation of 180 ° of the connection part 9 in a direction opposite to the previous one with the aim, as already indicated above, of not shearing the conducting wires 13.

Selon la réalisation décrite sur les figures 5 et 6, le passage de la partie de raccordement 9 d'une position à l'autre s'effectuera de la même manière que pour la réalisation précédente. Ainsi, sur les figures 5 et 6, les plots 4 sont reliés électriquement aux plages de contact 16 à 18, ce qui permet un montage en amont, du peigne de distribution 7. Après une rotation de 180° de la partie de raccordement 9, dans un sens ou dans l'autre, les plots 4 seront reliés électriquement aux plages de contact 19 à 21, ce qui permettra un montage du peigne 7 en aval. Dans cette réalisation, la course de rotation n'est pas limitée à 180°, ceci étant du au fait que les fils conducteurs 13 ne risquent pas d'être cisaillés, comme ceci est le cas dans la réalisation précédemment décrite. Il en résulte que deux rotations successives de 180° dans un même sens, de la partie de raccordement 9, pourront être opérées.According to the embodiment described in FIGS. 5 and 6, the passage of the connection part 9 from one position to the other will be carried out in the same manner as for the previous embodiment. Thus, in FIGS. 5 and 6, the studs 4 are electrically connected to the contact pads 16 to 18, which allows mounting upstream of the distribution comb 7. After a 180 ° rotation of the connection part 9, in one direction or the other, the pads 4 will be electrically connected to the contact pads 19 to 21, which will allow mounting of the comb 7 downstream. In this embodiment, the rotational stroke is not limited to 180 °, this being due to the fact that the conductive wires 13 are not likely to be sheared, as is the case in the embodiment described above. It follows that two successive rotations of 180 ° in the same direction, of the connecting part 9, can be operated.

Selon la réalisation décrite sur les figures 7 et 8, le passage d'une position permettant un montage du peigne 7 en amont (figure 7) à une position permettant un montage en aval du peigne (figure 8), s'effectuera en désolidarisant la partie principale 28 de la partie de raccordement 29. Cette désolidarisation sera obtenue en dégageant la partie de raccordement 29 de la rainure 28a. Puis cette partie de raccordement 29 sera retournée puis à nouveau engagée et fixée dans la rainure 28a (figure 8).According to the embodiment described in FIGS. 7 and 8, the transition from a position allowing mounting of the comb 7 upstream (FIG. 7) to a position allowing mounting downstream of the comb (FIG. 8), will be carried out by separating the main part 28 of the part of connection 29. This separation will be obtained by releasing the connection part 29 from the groove 28a. Then this connection part 29 will be turned over then again engaged and fixed in the groove 28a (Figure 8).

On a donc réalisé grâce à l'invention, un bloc auxiliaire notamment de signalisation de l'état d'un disjoncteur, de conception simple, pouvant être utilisé dans de nombreux pays puisqu'il autorise un montage du peigne de distribution aussi bien en amont qu'en aval des disjoncteurs.Thanks to the invention, an auxiliary unit has therefore been produced, in particular for signaling the state of a circuit breaker, of simple design, which can be used in many countries since it allows mounting of the distribution comb both upstream. only downstream of the circuit breakers.

Bien entendu l'invention n'est pas limitée aux modes de réalisation décrits et illustrés qui n'ont été donnés qu'à titre d'exemple.Of course, the invention is not limited to the embodiments described and illustrated which have been given only by way of example.

Au contraire, l'invention comprend tous les équivalents techniques des moyens décrits ainsi que leurs combinaisons si cellex- ci sont effectuées suivant son esprit.On the contrary, the invention includes all the technical equivalents of the means described as well as their combinations if the latter are carried out according to the spirit.
