Description

Dispositif de fixation et de contact pour barres de bus Fixing and contact device for bus bars
La présente invention a pour objet un dispositif de fixation et de contact pour barres de bus, également appelées "busbars" par l'homme du métier. Elle trouve notamment son utilisation dans le domaine des connexions à réaliser sur des systèmes de distribution électrique utilisant des plaques conductrices de barres de bus, et en particulier dans le domaine des connexions électriques destinées à transmettre des courants élevés dans le système à "barres de bus". L'intérêt de l'invention est de proposer un dispositif de fixation de faible profil et garantissant une bonne rétention du dispositif sur la plaque conductrice de barres de bus.The present invention relates to a fixing and contact device for bus bars, also called "busbars" by those skilled in the art. It finds its use in particular in the field of connections to be made on electrical distribution systems using conductive plates of bus bars, and in particular in the field of electrical connections intended to transmit high currents in the "bus bar" system. ". The advantage of the invention is to propose a fixing device with a low profile and guaranteeing good retention of the device on the conductive plate of bus bars.
De l'enseignement de l'art antérieur, on connaît notamment un clip de contact pour système de barres de bus décrit dans le document FR-A- 2,784,241. Ce clip de contact permet de fixer une douille conductrice sur une plaque conductrice à barres de bus. En effet, la plaque comporte une ouverture au travers de laquelle la douille est insérée. Cette douille comporte des épaulements préférentiellement allongés parallèlement au plan de la plaque et donc orthogonalement à l'axe d'insertion de la douille dans l'ouverture. Ces épaulements viennent en appui contre le pourtour de l'ouverture. Pour maintenir cette douille en position, on dispose d'un deuxième côté de la plaque, opposé au premier côté contre lequel les épaulements sont appuyés, un anneau présentant une surface intérieure débouchant sur une cavité torique. Cette cavité torique coopère avec des languettes découpées dans la paroi de la douille. Ces languettes forment des clips élastiques qui peuvent s'insérer dans la cavité torique. Les dimensions de cet anneau et la position des languettes est telle que la plaque conductrice est finalement retenue entre l'anneau et les épaulements de la douille.From the teaching of the prior art, a contact clip for a busbar system described in document FR-A-2,784,241 is known in particular. This contact clip makes it possible to fix a conductive socket on a conductive plate with bus bars. Indeed, the plate has an opening through which the sleeve is inserted. This socket has preferably elongated shoulders parallel to the plane of the plate and therefore orthogonally to the axis of insertion of the socket in the opening. These shoulders bear against the periphery of the opening. To maintain this socket in position, there is a second side of the plate, opposite the first side against which the shoulders are pressed, a ring having an inner surface opening onto a toric cavity. This toroidal cavity cooperates with tongues cut from the wall of the socket. These tabs form elastic clips which can be inserted into the toric cavity. The dimensions of this ring and the position of the tongues is such that the conductive plate is finally retained between the ring and the shoulders of the sleeve.
Le problème posé par de tels clips de rétention est qu'ils sont constitués de deux pièces fragiles, et très fortement ouvragées. De plus un tel clip de contact pour permettre à la plaque conductrice d'être connectée avec d'autres dispositifs complémentaires nécessite la présence d'un deuxième moyen de fixation, en plus de celui prévu pour retenir le clip sur la plaque. Ce deuxième moyen de fixation est généralement une vis qui traverse le canal de la douille pour venir appuyer une tête de vis en appui contre un pourtour du canal formé dans la douille. Cette vis traverse le canal et coopère avec un filetage prévu dans le dispositif complémentaire à connecter avec la plaque de barres de bus.The problem with such retention clips is that they consist of two fragile parts, and very heavily worked. In addition, such a contact clip to allow the conductive plate to be connected with other complementary devices requires the presence of a second fixing means, in addition to that provided for retaining the clip on the plate. This second fixing means is generally a screw which passes through the channel of the sleeve to come to bear a head of the screw in support against a periphery of the channel formed in the socket. This screw crosses the channel and cooperates with a thread provided in the complementary device to be connected with the busbar plate.
Les dispositifs de fixation et de contact montés sur les plaques conductrices de barres de bus posent un problème. En effet, d'une part le moyen pour retenir ce dispositif de contact sur la plaque est complexe, et enfin il est nécessairement volumineux en épaisseur du fait que la tête de vis du deuxième moyen de fixation de la plaque conductrice au dispositif complémentaire dépasse forcément du premier moyen de fixation. En effet, le premier moyen de fixation met en œuvre un jeu de languettes élastiques prévues pour coopérer avec un anneau. Ces languettes élastiques étant découpées dans la paroi de la douille, la seule contrainte que peut exercer cette tête de vis sur la paroi doit être appliquée au niveau du rebord du pourtour du canal, soit en augmentant la hauteur du dispositif. Par ailleurs la structure de la douille présentant des languettes élastiques pour conduire le courant de la barre de bus en direction d'un dispositif complémentaire est telle que lorsque la connexion est soumise à des chocs physiques, la qualité des contacts électriques établis n'est pas assurée avec la même régularité. En effet, lors de ces chocs, la surface de contact diminue, et par conséquent la résistance de contact augmente, ce qui atténue la transmission du signal.The fixing and contact devices mounted on the conductive plates of bus bars pose a problem. Indeed, on the one hand the means for retaining this contact device on the plate is complex, and finally it is necessarily bulky in thickness because the screw head of the second means for fixing the conductive plate to the complementary device necessarily exceeds of the first fixing means. Indeed, the first fixing means implements a set of elastic tongues intended to cooperate with a ring. These elastic tabs being cut from the wall of the socket, the only constraint that this screw head can exert on the wall must be applied at the edge of the periphery of the channel, ie by increasing the height of the device. Furthermore, the structure of the socket having elastic tabs to conduct the current from the busbar towards a complementary device is such that when the connection is subjected to physical shocks, the quality of the electrical contacts established is not insured with the same regularity. In fact, during these shocks, the contact surface decreases, and consequently the contact resistance increases, which attenuates the signal transmission.
L'invention a pour objet de fournir une solution aux problèmes posés ci dessus, en fournissant un dispositif de contact et de maintien présentant des moyens pour être retenu sur une plaque conductrice de barres de bus, et pour assurer la connexion d'une telle plaque avec un dispositif complémentaire en respectant les contraintes dimensionnelles et environnementales, et en garantissant une bonne qualité de contact. A cet effet, l'invention prévoit de mettre en en oeuvre un dispositif retenu mécaniquement de manière simple au travers d'une ouverture de la plaque. Ce dispositif comporte principalement une douille munie d'épaulements pour venir en appui contre un pourtour de l'ouverture d'un premier côté de la plaque. Il comporte également une bague d'une diamètre légèrement supérieur à celui de la douille. La bague peut être coulissée le long de la douille pour venir appuyer sur le pourtour de la même ouverture, mais du deuxième côté de la plaque. La plaque est ainsi pincée entre les deux éléments.The object of the invention is to provide a solution to the problems posed above, by providing a contact and holding device having means for being retained on a conductive plate of bus bars, and for ensuring the connection of such a plate. with a complementary device respecting dimensional and environmental constraints, and guaranteeing good contact quality. To this end, the invention provides for implementing a device mechanically retained in a simple manner through an opening in the plate. This device mainly comprises a bushing provided with shoulders to bear against a periphery of the opening of a first side of the plate. It also has a ring with a diameter slightly larger than that of the socket. The ring can be slid along the sleeve to press on the periphery of the same opening, but on the second side of the plate. The plate is thus pinched between the two elements.
Ces deux éléments sont retenus ensemble par le biais d'un moyen de vissage, par exemple une vis. Cette vis coopère directement avec la paroi intérieure d'un canal de la douille, et également avec un filetage réalisé dans le corps d'une dispositif complémentaire avec lequel la plaque doit être connectée. La coopération de la vis avec la paroi intérieure peut se traduire par l'appui d'une tête de cette vis contre des reliefs formés dans la paroi intérieure, et ou bien par la coopération entre le filetage de la vis et un filetage présentée dans la paroi intérieure de cette douille. La bague est retenue par ce moyen de vissage entre d'une part la plaque contre laquelle elle est appuyée et d'autre part contre le dispositif complémentaire qui est retenu par la vis. Les dimensions en longueur de la bague correspondent à la distance en longueur de la douille, la longueur de la douille étant considérée entre le plat de l'épaulement et l'extrémité opposée ouverte.These two elements are held together by means of a screwing means, for example a screw. This screw cooperates directly with the inner wall of a channel of the socket, and also with a thread produced in the body of a complementary device with which the plate must be connected. The cooperation of the screw with the interior wall can result in the support of a head of this screw against reliefs formed in the interior wall, or either by the cooperation between the thread of the screw and a thread presented in the inner wall of this socket. The ring is retained by this screwing means between on the one hand the plate against which it is pressed and on the other hand against the complementary device which is retained by the screw. The length dimensions of the ring correspond to the distance in length of the sleeve, the length of the sleeve being considered between the flat of the shoulder and the opposite open end.
L'invention a pour objet un dispositif de fixation et de contact à monter au travers d'une ouverture d'un conducteur en forme de plaque comportant une douille insérée dans l'ouverture, et telle que la douille comporte des épaulements pour venir en appui sur un pourtour de l'ouverture d'un premier côté de la plaque, caractérisé en ce qu'il comporte une bague montée autour de la douille, cette bague venant en appui contre le pourtour de l'ouverture d'un deuxième côté de la plaque, et en ce que la douille et la bague sont retenues au contact de la plaque par un moyen de vissage coopérant avec la douille et un dispositif complémentaire à connecter au conducteur. L'invention sera mieux comprise à la lecture de la description qui suit et à l'examen des figures qui l'accompagnent. Celles-ci ne sont présentées qu'à titre indicatif et nullement limitatif de l'invention. Les figures montrent :The subject of the invention is a fixing and contact device to be mounted through an opening in a plate-shaped conductor comprising a socket inserted into the opening, and such that the socket has shoulders for bearing on a periphery of the opening on a first side of the plate, characterized in that it comprises a ring mounted around the sleeve, this ring coming to bear against the periphery of the opening of a second side of the plate, and in that the sleeve and the ring are retained in contact with the plate by a screwing means cooperating with the sleeve and an additional device to be connected to the conductor. The invention will be better understood on reading the description which follows and on examining the figures which accompany it. These are presented for information only and in no way limit the invention. The figures show:
Figure 1 : Une vue en coupe transversale d'un dispositif de fixation et de contact selon l'invention monté sur une plaque; - Figure 2 : Une vue éclatée de dessus du dispositif selon l'invention avant montage sur une plaque.Figure 1: A cross-sectional view of a fixing and contact device according to the invention mounted on a plate; - Figure 2: An exploded top view of the device according to the invention before mounting on a plate.
La figure 1 montre un dispositif de fixation et de contact 1 monté sur une plaque conductrice 2. Le dispositif 1 est monté au travers d'une ouverture 3 formée dans la plaque 2. La plaque 2 est de préférence une plaque conductrice munie de barres de bus. Par exemple, ces barres de bus sont présentées sur une face supérieure 4 de la plaque 2.Figure 1 shows a fixing and contact device 1 mounted on a conductive plate 2. The device 1 is mounted through an opening 3 formed in the plate 2. The plate 2 is preferably a conductive plate provided with bars bus. For example, these bus bars are presented on an upper face 4 of the plate 2.
Le dispositif 1 comporte une douille 5 et une bague 6. La douille 5 est de préférence tubulaire pour coopérer avec l'ouverture 3 dans ce cas circulaire. Un diamètre extérieur de la douille 5 est légèrement inférieur au diamètre intérieur de l'ouverture 3. La douille 5 est insérée dans l'ouverture 3 selon un axe d'insertion orthogonal au plan formé par la plaque 2.The device 1 comprises a socket 5 and a ring 6. The socket 5 is preferably tubular to cooperate with the opening 3 in this circular case. An outside diameter of the socket 5 is slightly smaller than the inside diameter of the opening 3. The socket 5 is inserted into the opening 3 along an insertion axis orthogonal to the plane formed by the plate 2.
La douille 5 comporte de plus un épaulement 7 s'étendant radialement à l'axe d'insertion. Cet épaulement 7 confère localement un diamètre extérieur plus large à la douille 5. Au niveau de cet épaulement 7, le diamètre extérieur de la douille 5 est nettement supérieur au diamètre intérieur de l'ouverture 3. Par conséquent, dans la mesure où la douille 5 est insérée dans l'ouverture 3 depuis la face supérieure 4, l'épaulement 7 vient en appui sur le pourtour de l'ouverture 3 du côté de la face supérieure 4. Par exemple, cet épaulement 7 peut prendre la forme d'une collerette, comme représenté Figure 2. Cette collerette définit un anneau plat à large bord et dépasse radialement au niveau d'une première extrémité 8 de la douille 5.The sleeve 5 further comprises a shoulder 7 extending radially to the insertion axis. This shoulder 7 locally gives a larger outside diameter to the bushing 5. At the level of this shoulder 7, the outside diameter of the bushing 5 is clearly greater than the inside diameter of the opening 3. Consequently, insofar as the bushing 5 is inserted into the opening 3 from the upper face 4, the shoulder 7 bears on the periphery of the opening 3 on the side of the upper face 4. For example, this shoulder 7 can take the form of a collar, as shown in FIG. 2. This collar defines a flat ring with a wide edge and protrudes radially at a first end 8 of the sleeve 5.
La bague 6 peut coulisser le long des parois de la douille 5. Dans l'exemple décrit, la bague 6 est de forme tubulaire, et présente un diamètre intérieur légèrement supérieur au diamètre extérieur de la douille 5. Une fois que la douille 5 est insérée dans l'ouverture 3, une deuxième extrémité 9 de la douille 5 dépasse du côté de la face inférieure 10 de la plaque 2. La bague 6 est prévue pour être insérée autour de la douille 5 en l'insérant à partir de la deuxième extrémité 9. Ainsi une bordure d'une première extrémité 11 de la bague 6 vient en appui contre la face inférieure 10. Dans le cas où la bague est tubulaire, la bague 6 vient réaliser un appui circulaire autour de l'ouverture 3.The ring 6 can slide along the walls of the bushing 5. In the example described, the ring 6 is tubular in shape, and has an inside diameter slightly greater than the outside diameter of the bushing 5. Once the bushing 5 is inserted into the opening 3, a second end 9 of the sleeve 5 protrudes from the side of the underside 10 of the plate 2. The ring 6 is designed to be inserted around the sleeve 5 by inserting it from the second end 9. Thus an edge of a first end 11 of the ring 6 comes to bear against the lower face 10. In the case where the ring is tubular, the ring 6 comes to form a circular support around the opening 3.
De préférence la largeur de l'épaulement 7 est telle que la zone circulaire d'appui de la bague 6 se trouve en vis à vis de la zone d'appui de l'épaulement 7. La plaque 2 est coincée entre l'épaulement 7 de la douille 5 et la bague 6. Lorsque la plaque 2 est ainsi disposée, du côté de la face inférieure 10, la bague 6 et la douille s'allongent orthogonalement à la plaque 2 et ont respectivement une même longueur. En effet, la deuxième extrémité 9 de la douille 5 affleure dans un même plan que la deuxième extrémité 12 de la bague 6. La deuxième extrémité 12 est opposée à la première extrémité 11 , et est la partie de la bague 6 la plus éloignée de la plaque 2. Pour assurer le pinçage de la plaque 2 entre la douille 5 et la bague 6, le dispositif 1 comporte un moyen de fixation et de rapprochement de ces deux éléments l'un de l'autre. En effet, il comporte un moyen de vissage 13 pour coopérer avec la douille 5 et un dispositif complémentaire 14 avec lequel la plaque 2 doit être connectée. La connexion est assurée par le biais des pièces conductrices que sont la douille 5 et la bague 6. En effet, la douille 5 et la bague 6 peuvent être obtenues par usinage ou matriçage dans un matériau conducteur tel que le cuivre.Preferably the width of the shoulder 7 is such that the circular support area of the ring 6 is opposite the support area of the shoulder 7. The plate 2 is wedged between the shoulder 7 of the sleeve 5 and the ring 6. When the plate 2 is thus arranged, on the side of the lower face 10, the ring 6 and the sleeve extend orthogonally to the plate 2 and have the same length respectively. Indeed, the second end 9 of the sleeve 5 is flush in the same plane as the second end 12 of the ring 6. The second end 12 is opposite to the first end 11, and is the part of the ring 6 furthest from plate 2. To ensure the pinching of the plate 2 between the sleeve 5 and the ring 6, the device 1 comprises a means for fixing and bringing these two elements closer to one another. Indeed, it comprises a screwing means 13 for cooperating with the socket 5 and a complementary device 14 with which the plate 2 must be connected. The connection is ensured by means of the conductive parts that are the socket 5 and the ring 6. In fact, the socket 5 and the ring 6 can be obtained by machining or stamping in a conductive material such as copper.
Le moyen de vissage 13 comporte un corps fileté 15 prévu pour coopérer au moins avec un filetage complémentaire 16 prévu dans le dispositif complémentaire 14. Ainsi le moyen de vissage 13 est retenu mécaniquement sur le dispositif complémentaire 14. Le moyen de vissage 13 coopère également avec la douille 5. La douille 5 comporte un canal 17 pour y recevoir une portion du moyen de vissage 13. Dans un premier mode de réalisation, le moyen de vissage 13 comporte un corps fileté 15 tel qu'un pas de vis est présenté au niveau du canal 17 pour coopérer avec le corps fileté 15.The screwing means 13 comprises a threaded body 15 intended to cooperate at least with a complementary thread 16 provided in the complementary device 14. Thus the screwing means 13 is mechanically retained on the complementary device 14. The screwing means 13 also cooperates with the sleeve 5. The sleeve 5 has a channel 17 for receiving a portion of the screwing means 13. In a first embodiment, the screwing means 13 comprises a threaded body 15 such that a thread is presented at the level of the channel 17 to cooperate with the threaded body 15.
Dans un deuxième mode de réalisation, le moyen de vissage 13 comporte une tête de vis 18. Cette tête de vis 18 dépasse dans le canal 17. Dans ce cas, le canal 17 est débouchant aux deux extrémités respectivement 8 et 9. La vis 13 est alors insérée depuis l'extrémité 8 dans le canal 17. De plus ce canal 17 comporte alors un décrochement 19 au niveau de la paroi intérieure du canal 17. La tête 18 vient alors en butée contre ce décrochement 19 et seul le corps fileté 15 dépasse du côté de la deuxième extrémité 9. Selon ce deuxième mode de réalisation, la douille 1 peut néanmoins également présenter une portion filetée pour coopérer avec le corps fileté 15.In a second embodiment, the screwing means 13 comprises a screw head 18. This screw head 18 protrudes into the channel 17. In this case, the channel 17 opens out at the two ends respectively 8 and 9. The screw 13 is then inserted from the end 8 into the channel 17. In addition, this channel 17 then has a recess 19 at the interior wall of the channel 17. The head 18 then comes into abutment against this recess 19 and only the threaded body 15 protrudes from the side of the second end 9. According to this second embodiment, the sleeve 1 can nevertheless also have a threaded portion to cooperate with the threaded body 15.
Lorsque la douille 5 est retenue sur le dispositif complémentaire 14, alors la deuxième extrémité 9 est en appui contre une surface 20 de ce dispositif 14, surface 20 dans laquelle est formée le filetage complémentaire 16. Par ailleurs étant données les longueurs respectives de la douille 5 et de la bague 6, la bague 6 vient également en appui contre cette surface 20. En serrant le moyen de vissage 13, on rapproche la douille 5 du dispositif complémentaire 14, mais étant donné la hauteur de la bague 6, cette opération conduit à pincer la plaque 2. Par ailleurs, la plaque 2 peut être formée d'une superposition de couches successivement isolantes telles que 21 et conductrices telles que 22. Cette structure ne nuit pas à la connexion réalisée à partir du dispositif 1. En effet, les plaques telles que 22 ne devant pas être connectées par le dispositif 1 ne le sont pas dans la mesure où elles présentent une ouverture telle 3 nettement plus large et permettant ainsi le montage de la douille 5 et de la bague 6 sans avoir à rentrer en contact avec elles. La longueur de la bague 6 est telle qu'elle est supérieure à l'épaisseur des couches 21 et 22 superposées les unes sur les autres. Par ailleurs la longueur de la douille 5 est telle qu'elle est supérieure d'à peine l'épaisseur de la plaque 2 par rapport à la longueur de la bague 6.When the sleeve 5 is retained on the complementary device 14, then the second end 9 is in abutment against a surface 20 of this device 14, surface 20 in which the complementary thread 16 is formed. Furthermore, given the respective lengths of the sleeve 5 and the ring 6, the ring 6 also comes to bear against this surface 20. By tightening the screwing means 13, the socket 5 is brought closer to the complementary device 14, but given the height of the ring 6, this operation leads pinch the plate 2. Furthermore, the plate 2 can be formed of a superposition of successively insulating layers such as 21 and conductive layers such as 22. This structure does not harm the connection made from the device 1. In fact, the plates such as 22 do not should not be connected by the device 1 are not insofar as they have an opening such 3 much wider and thus allowing the mounting of the sleeve 5 and the ring 6 without having to come into contact with them. The length of the ring 6 is such that it is greater than the thickness of the layers 21 and 22 superimposed on each other. Furthermore, the length of the sleeve 5 is such that it is barely greater than the thickness of the plate 2 relative to the length of the ring 6.
Par l'invention, on peut proposer un dispositif 1 aux dimensions adaptées au nombre de couches 2, 21 et 22 empilées, et par ailleurs limiter l'encombrement du côté de la face supérieure 4 de la plaque 2. Dans un mode particulier de réalisation de l'invention, dans le cas où le moyen de vissage comporte une tête de vis 18, alors le dispositif 1 peut comporter une pièce de maintien 23 pour coopérer avec la géométrie de la tête de vis 18 et la géométrie interne de la paroi interne de la douille 5 pour empêcher les rotations indésirées. By the invention, it is possible to propose a device 1 with dimensions adapted to the number of layers 2, 21 and 22 stacked, and moreover limit the space requirement on the side of the upper face 4 of the plate 2. In a particular embodiment of the invention, in the case where the screwing means comprises a screw head 18, then the device 1 may include a holding part 23 for cooperating with the geometry of the screw head 18 and the internal geometry of the internal wall of sleeve 5 to prevent unwanted rotation.
