Description

L'invention concerne une borne de raccordement pour appareils d'installation électrique comprenant une boîte de serrage approximativement annulaire qui se trouve en prise avec un étrier de serrage par l'intermédiaire d'un boulon et qui, à l'intérieur d'une zone prédéterminée par l'étrier de serrage, est guidée de manière à pouvoir coulisser en hauteur dans un compartiment du boîtier de l'appareil de l'installation, par coopération avec le boulon et un dispo­sitif de retenue agissant de façon à réaliser une liaison commandée par une force.The invention relates to a connection terminal for electrical installation apparatus comprising an approximately annular clamping box which is engaged with a clamping bracket by means of a bolt and which, within a zone predetermined by the clamping bracket, is guided so as to be able to slide in height in a compartment of the housing of the apparatus of the installation, by cooperation with the bolt and a retaining device acting so as to produce a connection controlled by a strength.

Une telle borne de raccordement est par exemple décrite dans le DE-U-83 17 416 et elle est utilisée d'une manière avantageuse dans des disjoncteurs de protection de ligne pour le raccor­dement aussi bien de barres collectrices que de conducteurs unifilaires. Le blocage automatique de la boîte de serrage dans une position ajustée de manière quelconque est obtenu ici par l'intermédiaire d'un ressort à lame inséré dans le boîtier. Ce dispositif de retenue présente l'invonvé­nient d'une pièce supplémentaire pour laquelle sont nécessaires, en plus des coûts de fabrication, des frais de montage.Such a connection terminal is for example described in DE-U-83 17 416 and it is advantageously used in line protection circuit breakers for the connection of both busbars and single-wire conductors. Automatic locking of the clamping box in any position adjusted is obtained here by means of a leaf spring inserted in the housing. This retaining device has the disadvantage of an additional part for which are required, in addition to manufacturing costs, assembly costs.

L'invention a pour but de mettre au point, pour la borne de raccordement précitée, un dispositif de retenue qui soit de structure encore plus simple et qui soit conformé de façon favorable pour l'installation, tout en garantissant une fabrication peu coûteuse.The object of the invention is to develop, for the abovementioned connection terminal, a retaining device which is even simpler in structure and which is shaped favorably for installation, while guaranteeing inexpensive manufacture.

On résout ce problème par une borne de raccor­dement présentant les particularités caractéristiques de la revendication 1. Des perfectionnements et formes de réalisation avantageuses de l'invention font aussi l'objet des revendications secondaires.This problem is solved by a connection terminal having the characteristic features of claim 1. Advantageous improvements and embodiments of the invention are also the subject of the secondary claims.

L'invention est avantageuse dans la mesure où le dispositif de retenue pour la boîte de serrage déplaçable en hauteur peut être directement façonné au cours de la fabrication des pièces du boîtier. Une pièce supplémentaire disparaît ainsi et on économise des coûts de montage. Les saillies du dispositif de retenue sont dispo­sées de façon que la position supérieure de la boîte de serrage soit normalement conservée comme position de base au cours de la fabri­cation de l'appareil et que le boulon de la borne reçoive également une affectation supérieure correspondante. Cette position identique pour tous les appareils ne se modifie ni au cours du transport ni au cours de la manipulation à l'emplacement du montage.The invention is advantageous insofar as the retaining device for the height-adjustable clamping box can be directly shaped during the production of the parts of the housing. This eliminates an additional part and saves assembly costs. The protrusions of the retainer are arranged so that the upper position of the clamping box is normally kept as the basic position during the manufacture of the device and that the terminal bolt is also assigned a corresponding higher assignment. This identical position for all devices does not change either during transport or during handling at the mounting location.

Lors de la disposition en série courante de plusieurs appareils l'un à côté de l'autre, on peut ainsi introduire et raccorder sans problème, du côté de l'entrée, une barre collectrice en forme de peigne, respectivement entre l'étrier de serrage et la tête de boulon en position ouverte. Cette dernière est en supplément recou­verte par une plaque en console façonnée sur le boîtier et ainsi le boulon est assuré contre toute chute ainsi que contre tout contact accidentel. Une rotation correspondante du boulon de la borne suffit pour faire coulisser la boîte de serrage dans la position inférieure. La tête de boulon, qui s'appuie sur la plaque en console, presse vers le bas la boîte de serrage entre les saillies élastiques et la force de frottement qui se produit provoque un maintien en position fixe, sans cliquetis, de la boîte de serrage dans une position quelconque, par exemple pour une connexion de barres collectrices et de conducteurs unifilaires. Par une pression manuelle sur la tête de boulon, on peut en outre, sans problème, ajuster la position inférieur de la boîte de serrage avec sa section d'ouverture complète, par exemple pour des conducteurs multifilaires. La borne de raccordement suivant l'in­vention forme par conséquent un auxiliaire pratique d'installation.During the current series arrangement of several devices side by side, it is thus possible to introduce and connect without problem, on the side of the inlet, a comb-shaped collecting bar, respectively between the bracket of tightening and the bolt head in the open position. The latter is additionally covered by a console plate shaped on the housing and thus the bolt is insured against any fall as well as against any accidental contact. A corresponding rotation of the terminal bolt is enough to slide the clamping box into the lower position. The bolt head, which rests on the console plate, presses down the clamping box between the elastic projections and the friction force which occurs causes the clamping box to remain in a fixed position, without rattling. in any position, for example for connection of busbars and single-core conductors. By manual pressure on the bolt head, it is also possible, without problem, to adjust the lower position of the clamping box with its full opening section, for example for multi-wire conductors. The connection terminal according to the invention therefore forms a practical installation aid.

Other details and particularities of the invention will emerge from the description given below, without implied limitation and with reference to the attached drawings.
  • Figure 1 shows a sectional view of a first embodiment of a connection terminal according to the invention, from the side of the connection and with the clamping box located in an extreme upper position.
  • Figure 2 shows the connection terminal with a lowered clamping box which is in its position lower extreme.
  • Figures 3 and 4 show views, corresponding to the above representations, of a second embodiment of a connection terminal according to the invention.

La borne de raccordement comporte un étrier de serrage 1 métallique approximativement en forme de U ou de cadre, dans une vue de côté, qui est ancré de manière fixe dans un boîtier 2, constitué d'une matière isolante, d'un appareil d'installation non représenté de manière détaillée. Dans l'aile supérieure 1a de l'étrier de serrage il est prévu un trou de passage 1aʹ par lequel un boulon 3 pénètre dans un trou taraudé 4a d'une boîte de serrage 4 métallique, approximativement annulaire. Celle-ci entoure, à son tour, une aile inférieure 1b de l'étrier de serrage et elle est guidée de manière à pouvoir coulisser en hauteur dans un compartiment 2a du boîtier composé de deux coques 2b, 2c. La boîte de serrage 4 peut être amenée à coulisser à l'intérieur d'une zone de coulissement "s" depuis une position extrême supérieure (figures 1 ou respectivement 3) à une position extrême inférieure (figures 2 ou respectivement 4), en fonction de la profondeur de vissage du boulon 3. La forme de réalisation de l'étrier de serrage 1 garantit, en coopération avec le compartiment, le guidage de la boîte de serrage et une protection suffisante contre la torsion.The connection terminal includes a metal clamp 1 approximately in the shape of a U or a frame, in a side view, which is fixedly anchored in a housing 2, made of an insulating material, of an apparatus for installation not shown in detail. In the upper wing 1a of the clamping stirrup there is provided a passage hole 1aʹ through which a bolt 3 penetrates into a tapped hole 4a of an approximately annular metallic clamping box 4. This in turn surrounds a lower wing 1b of the clamping bracket and it is guided so as to be able to slide in height in a compartment 2a of the housing composed of two shells 2b, 2c. The clamping box 4 can be made to slide inside a sliding zone "s" from an extreme upper position (FIGS. 1 or respectively 3) to an extreme lower position (FIGS. 2 or respectively 4), depending the bolting depth of the bolt 3. The embodiment of the clamping bracket 1 guarantees, in cooperation with the compartment, the guidance of the clamping box and sufficient protection against torsion.

Afin que la boîte de serrage ne puisse pas glisser en va-et-vient d'une manière quelconque à l'intérieur de sa zone de coulissement, dans l'exemple de réalisation suivant les figures 1 et 2, un dispositif de retenue est agencé dans le compartiment sous la forme de deux saillies élastiques 2d, 2e qui sont disposées en ressaut latéralement et qui, dans la position extrême supérieure, prennent légèrement en dessous du côté inférieur 4b de la boîte de serrage, en fixant celle-ci dans sa position. Les saillies 2d, 2e, disposées l'une en face de l'autre, sont de préférence réalisées sous la forme de lèvres et elles sont, avec une flexibilité suffisante, façonnées, notamment par moulage, directement au cours de la fabrication, sur les coques 2b, 2c du boîtier en matériau thermoplastique.So that the clamping box cannot slide back and forth in any way inside its sliding zone, in the embodiment according to Figures 1 and 2, a retaining device is arranged in the compartment in the form of two elastic projections 2d, 2e which are arranged in lateral projection and which, in the extreme upper position, take slightly below the lower side 4b of the clamping box, fixing the latter in its position . The projections 2d, 2e, arranged one opposite the other, are preferably made in the form of lips and they are, with sufficient flexibility, shaped, in particular by molding, directly during manufacture, on the shells 2b, 2c of the housing made of thermoplastic material.

Dans l'exemple de réalisation selon les figures 3 et 4, une languette élastique 2g, qui est façonnée sur le boîtier dans la zone de l'aile supérieure 1a de l'étrier de serrage 1, est agencée comme dispositif de retenue dans le compartiment 2a. La languette élastique, préalablement cintrée dans le compartiment, représente, sous une forme isolée, une partie de la paroi du compartiment et effectue, depuis un côté, une pression élastique sur la boîte de serrage 4 qui est de ce fait pressée sur la paroi opposée du compartiment et est maintenue par une liaison commandée par une force. Cette dernière paroi peut en supplément être pourvue également d'une saillie en forme de lèvre 2dʹ pour déterminer ainsi la position supérieure de la boîte de serrage (figure 3).In the exemplary embodiment according to FIGS. 3 and 4, an elastic tongue 2g, which is shaped on the housing in the region of the upper wing 1a of the clamping bracket 1, is arranged as a retaining device in the compartment 2a. The elastic tongue, previously bent in the compartment, represents, in an isolated form, part of the wall of the compartment and exerts, from one side, an elastic pressure on the clamping box 4 which is therefore pressed on the opposite wall of the compartment and is held by a force-controlled link. This latter wall can additionally also be provided with a lip-shaped projection 2dʹ to thereby determine the upper position of the clamping box (FIG. 3).

Sur la boîte de serrage, fixée dans la position extrême supérieure entre l'aile inférieure 1b de l'étrier de serrage et les saillies 2d, 2e ou respectivement la saillie 2dʹ et la languette élastique 2g, on peut avantageusement raccorder une barre collectrice non repré­sentée qui peut être introduite entre une tête 3a du boulon de la borne et l'aile supérieure 1a de l'étrier de serrage. La tête de boulon, qui est recouverte partiellement par une plaque en console 2f, est accessible par l'intermédiaire d'une ouverture 2fʹ agencée de manière concentrique, de façon que le boulon puisse être actionné par un tourne vis. Dans le cas d'un filet à droite courant, une rotation vers la droite provoque le serrage de la barre collectrice.On the clamping box, fixed in the upper extreme position between the lower wing 1b of the clamping stirrup and the projections 2d, 2e or respectively the projection 2dʹ and the elastic tongue 2g, it is advantageously possible to connect a busbar not shown. which can be introduced between a head 3a of the terminal bolt and the upper wing 1a of the clamping bracket. The bolt head, which is partially covered by a plate in console 2f, is accessible via an opening 2fʹ arranged concentrically, so that the bolt can be actuated by a screwdriver. In the case of a current right-hand thread, a rotation to the right causes the busbar to be tightened.

Une rotation vers la gauche du boulon de la borne a au contraire pour effet que la tête de boulon parvient, par sa zone marginale, en appui sur la plaque en console 2f. Celle-ci forme ensuite une contre-butée fixe de façon que le boulon de la borne amène, conformément à la rotation vers la gauche, la boîte de serrage à coulisser entre les saillies élastiques, en direction de la position extrême inférieure. Pour transmettre une force de retenue suffisante à la boîte de serrage, celle-ci est pourvue de surfaces latérales 4c approximativement parallèles, dans la zone de glissement des saillies ou respectivement de la languette élastique.Rotating the terminal bolt to the left has the effect that the bolt head, by its marginal zone, comes to bear on the plate in console 2f. This then forms a fixed counter-stop so that the terminal bolt brings, in accordance with the rotation to the left, the clamping box to slide between the elastic projections, in the direction of the lower extreme position. To transmit a sufficient retaining force to the clamping box, the latter is provided with approximately parallel side surfaces 4c, in the sliding zone of the projections or respectively of the elastic tongue.

Le coulissement de la boîte de serrage dans la posi­tion inférieure peut être de même obtenu par une pression manuelle sur la tête de boulon. Dans la section complète de l'ouverture de la boîte de serrage, on peut ensuite raccorder un conducteur électrique unifilaire ou multifilaire et en cas de besoin, en dessous de la tête de boulon, encore une barre collectrice ou analogue. Par une rotation vers la droite ultérieure du boulon de la borne, la boîte de serrage est à nouveau tirée vers le haut entre les saillies, jusqu'à ce que, en fonction des sections transversales des conducteurs, le boulon de la borne et la boîte de serrage se bloquent réciproquement. L'étrier de serrage sert ici de butée destinée à s'opposer à la force de pressage produite par le boulon de la borne.The sliding of the clamping box in the lower position can also be obtained by manual pressure on the bolt head. In the complete section of the opening of the clamping box, it is then possible to connect a single-wire or multi-wire electrical conductor and if necessary, below the bolt head, still a busbar or the like. By a further clockwise rotation of the terminal bolt, the clamping box is again pulled upwards between the projections, until, depending on the cross-sections of the conductors, the terminal bolt and the box tighten each other. The clamping yoke serves here as a stop intended to oppose the pressing force produced by the terminal bolt.

Pour exploiter la course de coulissement de la boîte de serrage et les différentes possibilités de raccordement et de serrage, la longueur du boulon de la borne est accordée sur l'étrier de serrage. La coopération de toutes les pièces de la borne de raccordement donne un auxiliaire d'installation avantageux, la plaque en console 2f empêchant la chute du boulon de la borne et garantissant en outre une sécurité à l'encontre de tout contact involontaire avec des pièces conductrices de courant. Dans le cas d'un compartiment en matériau non suffisamment élastique, par exemple en matière plastique thermo­durcissable, un dispositif de retenue comparable pour la boîte de serrage peut être introduit, comme pièce supplémentaire, directement au cours de la fabrication ou encore ultérieurement au cours du montage.To exploit the sliding stroke of the clamping box and the various connection and tightening possibilities, the length of the terminal bolt is adjusted on the clamping bracket. The cooperation of all the parts of the connection terminal gives an advantageous installation aid, the console plate 2f preventing the fall of the terminal bolt and also guaranteeing safety against any involuntary contact with conductive parts current. In the case of a compartment made of material which is not sufficiently elastic, for example of thermosetting plastic, a comparable retaining device for the clamping box can be introduced, as an additional part, directly during manufacture or even later during mounting.

Il doit être entendu que la présente invention n'est en aucune façon limitée aux formes de réalisation décrites ci-dessus et que bien des modifications peuvent y être apportées sans sortir de son cadre.It should be understood that the present invention is in no way limited to the embodiments described above and that many modifications can be made without departing from its scope.
