Description

DOMAINE TECHNIQUETECHNICAL AREA

La présente invention concerne un appareil électrique destiné à être monté sur un support de montage au côté d'autres appareils du même type, et à être raccordé à un peigne de répartition apte à répartir l'énergie entre les différents appareils, ledit appareil étant logé dans un boîtier de forme sensiblement parallélépipédique comportant une face arrière de fixation au rail, une face avant comportant des moyens de manoeuvre de l'appareil, deux faces principales par lesquelles l'appareil est destiné à être juxtaposé à d'autres appareils sur le support de montage, et deux faces latérales comportant pour l'une, au moins une borne de raccordement dite d'entrée et pour l'autre, au moins une borne de raccordement dite de sortie, lesdites bornes étant montées dans les logements correspondants prévus dans le boîtier de l'appareil, la au moins une borne dite d'entrée comportant des moyens de connexion électrique de sa plage de raccordement à une dent dudit peigne,The present invention relates to an electrical appliance intended to be mounted on a mounting bracket alongside other appliances of the same type, and to be connected to a distribution comb able to distribute the energy between the different appliances, said appliance being housed in a substantially parallelepiped-shaped casing having a rear face for fixing to the rail, a front face comprising means for operating the apparatus, two main faces through which the apparatus is intended to be juxtaposed with other apparatus on the support for mounting, and two lateral faces comprising, for one, at least one said input connection terminal and for the other, at least one said output connection terminal, said terminals being mounted in the corresponding housings provided in the housing of the apparatus, the at least one said input terminal having means for electrical connection of its connection range to a tooth of said comb,

ETAT DE LA TECHNIQUESTATE OF THE ART

Habituellement, les appareils tels les disjoncteurs ou les relais montés sur un rail de montage dans un tableau électrique, et en particulier lorsqu'ils sont montés selon un pas de 9 mm sur le rail, sont connectés à la source d'alimentation électrique amont par le biais d'un peigne.Usually, devices such as circuit breakers or relays mounted on a mounting rail in an electrical panel, and in particular when they are mounted in a 9 mm pitch on the rail, are connected to the upstream power source by through a comb.

Or, la présence de ce peigne, associé à un mode de raccordement du type élastique, empêche toute translation de l'appareil de l'arrière vers l'avant, et il est donc difficile de dégager l'appareil des butées arrière afin de démonter l'appareil par une translation de haut en bas de manière à se dégager du peigne.However, the presence of this comb, associated with a connection mode of the elastic type, prevents any translation of the device from the back to the front, and it is therefore difficult to clear the apparatus of the rear stops to disassemble the device by a translation up and down so as to disengage the comb.

Une solution consiste à prévoir que l'une des butées soit amovible et présente une longue course, ce qui implique que le volume sous les appareils ne soit pas utilisé.One solution is to provide that one of the stops is removable and has a long run, which implies that the volume under the devices is not used.

On connaît également une solution qui consiste à utiliser des pattes de connexion montées sur l'appareil, lesquelles pattes viennent s'enficher sur le rail de distribution. Ainsi, le retrait de l'appareil est facilité par le fait que la présence du peigne est moins gênante dans ce cas pour effectuer cette manipulation.A solution is also known which consists of using connection tabs mounted on the apparatus, which tabs are plugged onto the distribution rail. Thus, the removal of the device is facilitated by the fact that the presence of the comb is less troublesome in this case to perform this manipulation.

EP2056326 décrit une borne de raccordement selon le préambule de la revendication 1. EP2056326 discloses a connection terminal according to the preamble of claim 1.

EXPOSE DE L'INVENTIONSUMMARY OF THE INVENTION

La présente invention résout ces problèmes et propose un appareil électrique monté sur un support de montage tel un rail, à être raccordé à un peigne de répartition, ledit appareil comportant au moins une borne étant de conception simple permettant un raccordement rapide et permettant de démonter ou de remonter facilement l'appareil sur le rail alors que le peigne est encore en place.The present invention solves these problems and proposes an electrical apparatus mounted on a mounting support such as a rail, to be connected to a distribution comb, said apparatus comprising at least one terminal being of simple design allowing a quick connection and allowing disassembly or to easily reassemble the device on the rail while the comb is still in place.

A cet effet, la présente invention a pour objet un appareil électrique du genre précédemment mentionné, selon la revendication 1.For this purpose, the subject of the present invention is an electrical appliance of the kind mentioned above, according to claim 1.

Grâce à ces caractéristiques, il est facile de déconnecter le peigne, en commençant par dégager l'appareil du support, ce qui est rendu possible et aisé par le fait que la plage de l'appareil coulisse dans l'appareil et reste fixe par rapport au peigne. Puis une autre translation du peigne permettra de retirer la ou les dents du peignes insérées dans l'appareil suivant une autre direction.Thanks to these characteristics, it is easy to disconnect the comb, starting by disengaging the device from the support, which is made possible and easy by the fact that the range of the device slides in the device and remains fixed relative comb. Then another translation of the comb will remove the teeth or the combs inserted into the device in another direction.

Selon une réalisation particulière préférée, le support de fixation précité comporte un rail et les moyens de fixation de l'appareil audit rail comportent un évidement prévu dans la face arrière de l'appareil, deux encoches prévues aux deux extrémités dudit évidement, les deux encoches étant destinées à recevoir respectivement les deux bords libres longitudinaux du rail, et deux butées coopérant avec lesdites encoches de manière à retenir lesdits bords longitudinaux du rail à l'intérieur des encoches, l'une au moins des butées étant amovible de manière à permettre le retrait de l'appareil du rail.According to a particular preferred embodiment, the aforementioned mounting bracket comprises a rail and the means for fixing the device to said rail comprise a recess provided in the rear face of the device, two notches provided at both ends of said recess, the two notches. being intended to respectively receive the two longitudinal free edges of the rail, and two stops cooperating with said notches so as to retain said longitudinal edges of the rail inside the notches, at least one of the stops being removable so as to allow the removing the device from the rail.

Ainsi, la déconnexion de l'appareil par rapport au peigne sera réalisée tout d'abord en désactivant le verrou constitué par la butée mobile précitée, puis en déplaçant l'appareil suivant deux mouvements de translation respectivement un premier mouvement suivant une direction sensiblement perpendiculaire au plan du rail et une second mouvement suivant une direction parallèle au rail et perpendiculaire à la direction longitudinale du peigne.Thus, the disconnection of the apparatus relative to the comb will be performed firstly by deactivating the latch constituted by the aforementioned movable stop, then moving the apparatus in two translation movements respectively a first movement in a direction substantially perpendicular to the plane of the rail and a second movement in a direction parallel to the rail and perpendicular to the longitudinal direction of the comb.

Selon une caractéristique particulière préférée, la face arrière de l'appareil comporte, du fait de la présence de l'évidement précité, une portion de paroi extérieure et une portion de paroi intérieure décalée par rapport à la portion de paroi extérieure suivant une direction sensiblement perpendiculaire au plan de fixation, et la longueur de la course en translation précitée de la plage dans son logement correspond sensiblement à la distance séparant ces deux portions de surface.According to a particular preferred feature, the rear face of the apparatus comprises, due to the presence of the aforementioned recess, an outer wall portion and an inner wall portion offset from the outer wall portion in a direction substantially perpendicular to the attachment plane, and the length of the aforementioned translation stroke of the range in its housing substantially corresponds to the distance separating these two surface portions.

Selon une autre caractéristique particulière préférée, cette borne comporte une plage de raccordement fixée et reliée électriquement à un conducteur souple, ledit conducteur souple étant relié électriquement à un conducteur interne appartenant à l'appareil. De cette manière, le débattement de l'appareil est plus important, ce qui permet d'extraire l'appareil sans forcer sur le peigne.According to another particular preferred feature, this terminal has a connection pad fixed and electrically connected to a flexible conductor, said flexible conductor being electrically connected to an inner conductor belonging to the apparatus. In this way, the movement of the device is greater, which allows to extract the device without forcing the comb.

Selon l'invention cette borne comporte des moyens de connexion du type rapide à ressort destinés au raccordement électrique de la borne à une dent appartenant au peigne précité.According to the invention this terminal comprises spring-type connection means for the electrical connection of the terminal to a tooth belonging to the aforementioned comb.

Selon l'invention cette borne comporte en outre des moyens de connexion dits classiques à vis destinés à permettre la connexion d'un câble à la borne, lesdits moyens de connexion à vis comportant une cage mobile en translation dans un logement du boîtier de l'appareil entre une position de connexion du câble dans la quelle ledit câble est serré entre la plage de raccordement précitée de la borne et la cage, et une position de déconnexion du câble.According to the invention, this terminal further comprises so-called conventional screw connection means intended to allow the connection of a cable to the terminal, said screw connection means comprising a mobile cage in translation in a housing of the housing of the apparatus between a connection position of the cable in which said cable is clamped between the aforementioned connection range of the terminal and the cage, and a disconnecting position of the cable.

Selon l'invention la plage de raccordement précitée comporte une partie sensiblement en forme de U montée coulissante à l'intérieur du logement de borne précité, ladite plage comportant une première aile reliée électriquement au conducteur souple précité, une base comportant un orifice destiné au passage d'une dent de peigne, et une seconde aile apte à coopérer avec le cage de manière permettre la connexion d'un câble, ladite plage étant destinée à recevoir un ressort monté à l'intérieur du U, ledit ressort étant en appui d'une part sur la seconde aile du U et d'autre part, sur la dent du peigne en position de connexion du peigne, de manière à rappeler ladite dent en contact avec la première aile précitée de la plage de raccordement.According to the invention, the above-mentioned connection zone comprises a substantially U-shaped portion slidably mounted inside the aforementioned terminal housing, said zone comprising a first flange electrically connected to the aforementioned flexible conductor, a base comprising an orifice intended for the passage a comb tooth, and a second wing adapted to cooperate with the cage so as to allow the connection of a cable, said range being intended to receive a spring mounted inside the U, said spring being in support of a part on the second wing of the U and on the other hand, on the comb tooth in comb connection position, so as to return said tooth in contact with the aforementioned first wing of the connection pad.

Selon une autre caractéristique particulière préférée, la connexion du câble est réalisée par serrage dudit câble entre la cage et la plage de raccordement.According to another particular preferred feature, the cable connection is made by clamping said cable between the cage and the connection pad.

Avantageusement, le ressort précité présente une forme semi-cylindrique.Advantageously, the aforementioned spring has a semi-cylindrical shape.

Selon une autre caractéristique préférée, le boîtier de l'appareil comporte deux orifices destinés à permettre respectivement l'introduction d'une dent de peigne et d'un câble, lesdits orifices se trouvant respectivement en regard des moyens de connexion dits rapides et des moyens de connexion à vis, et ladite borne comporte des moyens pour obturer l'orifice d'accès du boîtier destiné à l'introduction d'un câble dans une position de l'appareil correspondant à une position dégagée du rail, et à libérer cet orifice dans une position de l'appareil correspondant à une position fixée sur le rail de l'appareil.According to another preferred feature, the housing of the apparatus comprises two orifices intended to allow respectively the introduction of a comb tooth and a cable, said orifices respectively being opposite said so-called connection means and means connection to screw, and said terminal comprises means for closing the access port of the housing for the introduction of a cable into a position of the device corresponding to a position released from the rail, and to release this orifice in a position of the apparatus corresponding to a position fixed on the rail of the apparatus.

Selon une autre caractéristique préférée, ces moyens comportent un volet réalisé en un matériau isolant, ledit volet étant solidaire de la plage de raccordement précitée de la borne.According to another preferred feature, these means comprise a shutter made of an insulating material, said shutter being integral with the above-mentioned connection range of the terminal.

Selon une caractéristique préférée, cet appareil électrique comporte deux bornes comportant les caractéristiques précédemment mentionnées prises seules ou en combinaison, lesdites bornes étant décalées suivant la profondeur de l'appareil, celle-ci étant définie sensiblement perpendiculairement au plan de fixation du support de fixation, de manière à permettre le raccordement de ces deux bornes respectivement à deux dents de peigne adjacentes, ledit peigne comportant deux rangées de dents, à savoir une rangée de dent distribuant le neutre et une rangée de dents distribuant les différentes phases, avec interposition d'une dent distribuant le neutre entre deux dents de phase successives.According to a preferred characteristic, this electrical apparatus comprises two terminals comprising the aforementioned characteristics taken alone or in combination, said terminals being offset according to the depth of the apparatus, the latter being defined substantially perpendicular to the fixing plane of the fixing support, so as to allow the connection of these two terminals respectively to two adjacent comb teeth, said comb having two rows of teeth, namely a row of teeth distributing the neutral and a row of teeth distributing the different phases, with the interposition of a tooth distributing the neutral between two successive phase teeth.

EXPOSE DETAILLE DE MODES DE REALISATION PARTICULIERSDETAILED DESCRIPTION OF PARTICULAR EMBODIMENTS

Sur les figures, on voit un appareil de protection électrique A tel un disjoncteur, monté sur un rail de montage R, ledit appareil étant destiné à être juxtaposé sur le rail à d'autres appareils du même type (non représentés), cet ensemble étant destiné à être monté à l'intérieur d'un tableau électrique.In the figures, we see an electrical protection device A such a circuit breaker, mounted on a mounting rail R, said apparatus being intended to be juxtaposed on the rail to other devices of the same type (not shown), this assembly being intended to be mounted inside an electrical panel.

De manière connue en soi, chaque appareil A est logé dans un boîtier E de forme sensiblement parallélépipédique comportant une face arrière 1 de fixation au rail R, une face avant (non visible sur cette figure) comportant un organe de manoeuvre manuel, deux faces principales 2,3 par lesquelles les appareils sont juxtaposés sur le rail, et deux faces latérales 4,5 comportant une face dite supérieure 4 comportant des orifices o,r d'accès à des bornes 6,7 dites amont logées dans la partie supérieure de l'appareil, et une face dite inférieure non représentée sur cette figure comportant des orifices d'accès à des bornes dites de départ logées dans la partie inférieure de l'appareil, les parties supérieure et inférieure étant définies par rapport au rail de montage et seule la partie supérieure de l'appareil et les bornes amont étant visibles sur les figures.In a manner known per se, each apparatus A is housed in a housing E of substantially parallelepiped shape having a rear face 1 for attachment to the rail R, a front face (not visible in this figure) having a manual actuating member, two main faces 2,3 by which the devices are juxtaposed on the rail, and two side faces 4,5 having a so-called upper face 4 having orifices o, r access to terminals 6,7 said upstream housed in the upper part of the apparatus, and a so-called lower face not shown in this figure having access orifices to said terminals of departure housed in the lower part of the apparatus, the upper and lower parts lower being defined relative to the mounting rail and only the upper part of the apparatus and the upstream terminals being visible in the figures.

La fixation de l'appareil sur le rail est réalisée au moyen d'une part d'un évidement 8 prévu dans la paroi arrière de l'appareil, et d'autre part, de deux encoches 34 prévues aux deux extrémités dudit évidement 8 et formées respectivement par deux butées 9 (dont seule l'une est visible sur les figures) respectivement supérieure et inférieure, lesdites butées étant destinées à coopérer respectivement avec deux bords longitudinaux 10,11 pliés sensiblement en équerre du rail de manière à empêcher le mouvement de l'arrière vers l'avant de l'appareil A de manière à retenir ledit appareil A sur le rail R.Fixing the apparatus on the rail is carried out by means of a part of a recess 8 provided in the rear wall of the apparatus and, on the other hand, of two notches 34 provided at the two ends of said recess 8 and formed respectively by two stops 9 (only one of which is visible in the figures) respectively upper and lower, said stops being intended to cooperate respectively with two longitudinal edges 10,11 folded substantially square of the rail so as to prevent the movement of the rear towards the front of the apparatus A so as to hold said apparatus A on the rail R.

De manière connue en soi, cette butée supérieure 9 est amovible de manière à permettre le montage de l'appareil A sur le rail R et son retrait du rail. Cette butée est constituée principalement par un verrou 12 comportant une partie coulissante par rapport au boîtier de l'appareil, ledit verrou comportant à l'une de ses extrémités une partie formant bec 13 apte à coopérer avec le rail R et à son extrémité opposée, un moyen de préhension 14 apte à être déplacé manuellement de manière à escamoter la butée 9 par rapport au rail et à autoriser ainsi le démontage de l'appareil par rapport au rail R.In a manner known per se, this upper stop 9 is removable so as to allow the mounting of the apparatus A on the rail R and its removal from the rail. This stop consists mainly of a latch 12 having a sliding portion relative to the housing of the apparatus, said latch comprising at one of its ends a nose portion 13 adapted to cooperate with the rail R and at its opposite end, a gripping means 14 adapted to be moved manually so as to retract the abutment 9 relative to the rail and thus allow the disassembly of the apparatus relative to the rail R.

On notera qu'avantageusement, ces deux butées sont escamotables.Note that advantageously, these two stops are retractable.

Cet appareil comporte, montées à l'intérieure de sa partie supérieure, deux bornes amont 6,7 respectivement reliées électriquement à un conducteur de phase et à un conducteur de neutre de l'appareil.This apparatus comprises, mounted inside its upper part, two upstream terminals 6,7 respectively electrically connected to a phase conductor and a neutral conductor of the apparatus.

Chacune de ces bornes est du type à double raccordement et comporte des moyens de connexion 15 du type à vis destinés à permettre le raccordement électrique d'un câble c et des moyens de connexion du type rapide 16 à ressort permettant la connexion d'une dent appartenant à un peigne P de répartition, s'agissant d'une dent de phase dp pour la borne située à gauche de l'appareil sur les figures et d'une dent de neutre dn pour la borne située à droite de l'appareil sur les figures.Each of these terminals is of the double-connection type and comprises connection means 15 of the screw type intended to allow the electrical connection of a cable c and spring-type connection means 16 spring-type for the connection of a tooth belonging to a distribution comb P, in the case of a phase tooth dp for the terminal located on the left of the device in the figures and a neutral tooth dn for the terminal located on the right of the device on the figures.

A cet effet, le boîtier de l'appareil comporte une ouverture 17 comportant une partie 18 en regard des moyens de connexion à vis destinée à permettre le passage du câble et une partie 19 en regard des moyens de connexion dits rapide destinée à permettre le passage d'une dent de peigne.For this purpose, the housing of the apparatus comprises an opening 17 comprising a portion 18 facing the screw connection means intended to allow the passage of the cable and a portion 19 facing the so-called rapid connection means intended to allow the passage of a comb tooth.

Les moyens de connexion à vis 15 comprennent une cage 20 montée coulissante dans un logement 21 du boîtier de l'appareil et apte à être déplacée au moyen d'une vis 22 montée à rotation par rapport au boîtier de l'appareil selon son axe longitudinal, de telle manière que le serrage de la vis 22 entraîne un déplacement vers le haut (sur la figure) de la cage 20, ce déplacement ayant pour effet de serrer un câble c préalablement introduit dans la borne entre la plage de raccordement 23 et la cage 20, la plage de raccordement 23 étant reliée électriquement à l'un des conducteurs internes au moyen d'une tresse 24.The screw connection means 15 comprise a cage 20 slidably mounted in a housing 21 of the housing of the apparatus and adapted to be displaced by means of a screw 22 mounted to rotate relative to the housing of the apparatus along its longitudinal axis. , so that the tightening of the screw 22 causes an upward movement (in the figure) of the cage 20, this displacement having the effect of tightening a cable c previously introduced into the terminal between the connection pad 23 and the cage 20, the connection pad 23 being electrically connected to one of the internal conductors by means of a braid 24.

Les moyens de connexion du type rapide 16 comprennent une plage de raccordement 23 de la borne précitée sensiblement en forme de U comportant une base 25 et deux ailes 26,27, dont l'une dite première 26 est reliée électriquement à la tresse précitée 24 tandis que l'autre, dite seconde 27, est destinée à coopérer avec le câble précité c.The quick-type connection means 16 comprise a connection pad 23 of the aforesaid substantially U-shaped terminal comprising a base 25 and two wings 26, 27, one of which said first 26 is electrically connected to the aforementioned braid 24 while that the other, said second 27, is intended to cooperate with the aforementioned cable c.

Ces moyens de connexion du type rapide 16 comportent également un ressort 28 apte à être placé à l'intérieur de ladite plage 23, ledit ressort étant de forme sensiblement cylindrique et étant destiné à venir en appui d'une part sur la seconde aile 27 du U et d'autre part, sur une dent de peigne 29 lorsqu'une telle dent est introduite à l'intérieur de la plage, de manière que cette dent soit enserrée élastiquement entre ce ressort 28 et cette aile dite première 26 du U précité.These fast type connection means 16 also comprise a spring 28 adapted to be placed inside said range 23, said spring being of substantially cylindrical shape and being intended to bear on the one hand on the second wing 27 of the U and secondly, on a comb tooth 29 when such a tooth is introduced within the range, so that the tooth is clamped elastically between the spring 28 and said first said wing 26 of the aforementioned U.

Selon l'invention, cette plage de raccordement 23 est montée coulissante dans le logement 21 de la borne entre deux positions respectivement une première position dans laquelle celle-ci est située à l'avant de l'appareil et une seconde position dans laquelle celle-ci est située vers l'arrière de l'appareil, ce coulissement de la plage 23 étant rendu possible par le fait que la plage de raccordement 23 est reliée électriquement à une tresse souple 24.According to the invention, this connection pad 23 is slidably mounted in the housing 21 of the terminal between two positions respectively a first position in which it is located at the front of the apparatus and a second position in which the latter it is located towards the rear of the apparatus, this sliding of the strip 23 being made possible by the fact that the connection pad 23 is electrically connected to a flexible braid 24.

On notera également que la plage de raccordement précitée 23 comporte un premier capot 30 et un second capot 31, dont la fonction sera expliquée dans ce qui suit, le premier capot 30 étant fixé à la plage 23 par l'intermédiaire de plots 32 prévus sur le premier capot 30 coopérant avec des orifices 33 prévus dans la plage 23, et pour le second par enfichage à force d'une partie de la plage dans un orifice correspondant du capot dit second 31.It will also be noted that the above-mentioned connection area 23 comprises a first cover 30 and a second cover 31, the function of which will be explained in the following, the first cover 30 being fixed to the strip 23 by means of pads 32 provided on the first cover 30 cooperating with orifices 33 provided in the range 23, and for the second by plugging a portion of the range into a corresponding orifice of the so-called second cover 31.

Le fonctionnement de la borne selon une réalisation préférée de l'invention telle que précédemment décrite va être décrit dans ce qui suit en référence aux figures :

  • Sur les figures 1 à 3, l'appareil A est en position fixée sur le rail R, le verrou 12 ayant été amené dans une position de fixation sur le rail R.
The operation of the terminal according to a preferred embodiment of the invention as described above will be described in the following with reference to the figures:
  • On the Figures 1 to 3 , the apparatus A is in a fixed position on the rail R, the latch 12 having been brought into a fixing position on the rail R.

La plage de raccordement 23 a été amenée dans la première position de manière à permettre le raccordement d'une dent de peigne 29 se trouvant en regard lors d'un raccordement par peigne P tel que ceci est illustré sur la figure 2.The connection pad 23 has been brought into the first position so as to allow the connection of a comb tooth 29 facing each other during a comb connection P as shown in FIG. figure 2 .

On notera que bien que les deux bornes amont 6,7 de l'appareil A soient décalées suivant la profondeur de l'appareil, leur principe de fonctionnement est le même.Note that although the two upstream terminals 6,7 of the apparatus A are shifted according to the depth of the apparatus, their operating principle is the same.

Ainsi, sur les figures 1 à 3, ces deux bornes 6,7 se trouvent dans leur première position, c'est-à-dire permettant un raccordement respectivement à une dent de phase dp et à une dent de neutre dn du peigne P, ledit peigne P étant de manière connue en soi du genre comportant une rangée de dents de phase et une rangée de dents de neutre.Thus, on the Figures 1 to 3 these two terminals 6,7 are in their first position, that is to say, allowing a respective connection to a phase tooth dp and to a neutral tooth dn of the comb P, said comb P being in a known manner in self of the kind comprising a row of phase teeth and a row of neutral teeth.

Dans cette position illustrée sur les figures 1,2 et 3, le volet dit second 31 est escamoté à l'intérieur du boîtier de l'appareil tandis que le volet dit premier 30 est situé à l'intérieur de l'ouverture 17 prévue dans le boîtier, de telle manière qu'il se trouve sensiblement au milieu et autorise l'accès en même temps à un câble c et à une dent de peigne 29.In this position illustrated on the figures 1 , 2 and 3 the so-called second flap 31 is retracted inside the casing of the apparatus while the so-called first flap 30 is located inside the opening 17 provided in the casing, so that it is substantially in the middle and allows access at the same time to a cable c and a comb tooth 29.

Les figures 4 à 6 illustrent le démontage de l'appareil A, peigne en place. Sur la figure 4, l'utilisateur a exercé une traction sur le verrou 12 et a entrainé l'appareil A vers l'avant, c'est-à-dire du côté opposé au rail, par une translation de l'appareil suivant une direction d1 sensiblement perpendiculaire au plan Q de fixation du rail sur une longueur de course d'environ la distance e séparant la paroi extérieure 35 de la paroi intérieure 36 de l'appareil.The Figures 4 to 6 illustrate the disassembly of the apparatus A, comb in place. On the figure 4 the user has pulled the latch 12 and pulled the apparatus A forwards, that is to say on the side opposite the rail, by a translation of the apparatus in a substantially perpendicular direction d1 at the plane Q of fixing the rail over a running length of approximately the distance e between the outer wall 35 of the inner wall 36 of the apparatus.

Pendant cette translation de l'appareil, du fait que le peigne P est resté en place, la plage 23 s'est déplacé en translation à l'intérieur du logement 21 de borne en direction du rail R jusqu'à sa seconde position.During this translation of the apparatus, because the comb P remained in place, the track 23 has moved in translation inside the terminal housing 21 towards the rail R to its second position.

Dans cette position illustrée sur les figures 5 et 6, du fait que l'appareil a été dégagé du rail R, il est possible de déplacer l'appareil suivant une direction d2 parallèle au plan de fixation Q et sensiblement perpendiculaire à la direction longitudinale I du peigne P suivant la flèche selon la figure 6, de manière à déconnecter le peigne P de la borne en retirant les dents de peigne 29 de cette borne.In this position illustrated on the figures 5 and 6 since the apparatus has been disengaged from the rail R, it is possible to move the apparatus in a direction d2 parallel to the attachment plane Q and substantially perpendicular to the longitudinal direction I of the comb P along the arrow according to the figure 6 , in a way to disconnect comb P from the terminal by removing the comb teeth 29 from this terminal.

Dans cette position, lorsque la plage de raccordement 23 est en position basse, le volet dit premier 30 obture la partie de l'orifice du boîtier destiné à l'introduction du câble c, tandis que le volet dit second 31 obture la partie supérieure de l'ouverture 17 située au-dessus de la plage de raccordement 23. Ainsi, un raccordement par câble c n'est plus possible lorsque l'appareil est démonté du rail R.In this position, when the connection zone 23 is in the low position, the so-called first shutter closes the portion of the orifice of the housing for the introduction of the cable c, while the so-called second shutter 31 closes the upper part of the the opening 17 located above the connection pad 23. Thus, a cable connection c is no longer possible when the device is removed from the rail R.

Les figures 8 et 9 illustrent la démarche inverse qui consiste à raccorder l'appareil A au peigne P, puis à monter l'appareil sur le rail.The figures 8 and 9 illustrate the opposite approach which consists of connecting the device A to the comb P, then to mount the device on the rail.

Ainsi, à partir de la figure 8, sur laquelle l'appareil a été raccordé au peigne, l'utilisateur déplace l'appareil par translation suivant une direction d1 sensiblement perpendiculaire au plan de fixation Q, jusqu'à l'introduction complète du rail dans l'évidement 8 de l'appareil A, après avoir exercé une traction sur l'organe de manoeuvre 14 du verrou 12 de manière à permettre cette introduction. Puis, l'organe de manoeuvre du verrou est libéré, ce qui réalise la fixation de l'appareil A sur le rail R, tel qu'illustré sur la figure 9.So, from the figure 8 , to which the apparatus has been connected to the comb, the user moves the apparatus by translation in a direction d1 substantially perpendicular to the plane of attachment Q, until the complete introduction of the rail into the recess 8 of the apparatus A, after having exerted traction on the operating member 14 of the latch 12 so as to allow this introduction. Then, the actuating member of the lock is released, which carries the attachment of the apparatus A on the rail R, as illustrated on the figure 9 .

Pendant ce mouvement en translation de l'appareil A, la plage de raccordement 23 s'est déplacée également en translation à l'intérieur de son logement 21, du fait de la présence de la dent de peigne 29 dans la borne, laquelle dent de peigne reste fixe par rapport au rail R.During this movement in translation of the apparatus A, the connection area 23 has also moved in translation inside its housing 21, because of the presence of the comb tooth 29 in the terminal, which tooth of comb remains fixed relative to rail R.

Ce déplacement de la plage de raccordement 23 a entraîné le déplacement des deux volets 30,31 de manière que le second volet 31 se retrouve dans une position escamotée, tandis que le premier volet 30 se retrouve sensiblement au milieu de l'ouverture 17 d'accès de manière à permettre l'introduction dans la borne à la fois d'un câble c et d'une dent de peigne 29.This displacement of the connection pad 23 has caused the two flaps 30, 31 to move so that the second flap 31 is in a retracted position, whereas the first flap 30 is substantially in the middle of the opening 17 of access so as to allow the introduction into the terminal of both a cable c and a comb tooth 29.

On a donc réalisé grâce à l'invention une borne de raccordement permettant de réaliser un double raccordement, laquelle borne permet à l'appareil dans lequel elle est montée d'être démonté, alors que le peigne est en place, grâce à la possibilité pour la plage de raccordement de coulisser dans son logement. L'invention permet également d'empêcher le raccordement à un câble de l'appareil lorsque celui-ci est démonté du rail de montage.Thus, thanks to the invention, a connection terminal has been realized which makes it possible to make a double connection, which terminal allows the apparatus in which it is mounted to be disassembled, whereas the comb is in place, thanks to the possibility of the connection range to slide in its housing. The invention also makes it possible to prevent the connection to a cable of the apparatus when the latter is removed from the mounting rail.

L'invention s'applique avantageusement lorsque le volume situé sous les appareils est utilisé.The invention is advantageously applied when the volume located under the apparatus is used.

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

L'invention comprend tous les équivalents techniques des moyens décrits ainsi que leurs combinaisons si celles-ci sont réalisées suivant les revendications.The invention comprises all the technical equivalents of the means described and their combinations if they are made according to the claims.
