Description
La présente invention concerne un dispositif de connexion d'un conducteur à une borne électrique, du type comportant au moins une lame ressort prévue pour plaquer ledit conducteur, lors de son enfichage dans le dispositif, contre une surface conductrice reliée électriquement à ladite borne.The present invention relates to a device for connecting a conductor to an electrical terminal, of the type comprising at least one spring blade provided for pressing said conductor, when plugged into the device, against a conductive surface electrically connected to said terminal.
L'invention a pour but d'atténuer les efforts d'enfichage du conducteur dans le dispositif de connexion. L'invention a également trait à un appareil électrique modulaire, par exemple du type disjoncteur ou interrupteur différentiel, qui est muni d'un tel dispositif de connexion.The invention aims to mitigate the driver's plugging efforts in the connection device. The invention also relates to a modular electrical appliance, for example of the type circuit breaker or differential switch, which is provided with such a connection device.
Les dispositifs qui sont particulièrement visés par l'invention sont ceux qui permettent l'enfichage d'une partie d'un système de distribution électrique de type barre de pontage à fourches ou à languettes dans un connecteur de raccordement à lame(s) ressort(s) par exemple d'un appareil électrique modulaire. Lesdites lames doivent assurer un bon contact électrique qui ne s'altère pas avec le temps, et développent par conséquent une force de contact suffisante pour y parvenir. Or, la force d'enfichage du conducteur, par exemple une languette d'une barre de pontage, est directement liée à la force de contact développée par le ressort.The devices which are particularly targeted by the invention are those which allow the plugging of a part of a fork or tongue bridging type electrical distribution system into a spring blade connection connector (s) ( s) for example a modular electrical device. Said blades must ensure a good electrical contact that does not deteriorate over time, and therefore develop a contact force sufficient to achieve it. However, the driver's insertion force, for example a tab of a bridging bar, is directly related to the contact force developed by the spring.
Actuellement, lorsqu'elle est au repos, la lame ressort d'un tel connecteur est en appui sur la surface conductrice de la borne, et la course de déplacement du ressort est par conséquent égale à l'épaisseur de la languette qui est enfichée dans le dispositif de connexion.Currently, when it is at rest, the leaf spring of such a connector bears on the conductive surface of the terminal, and the displacement stroke of the spring is therefore equal to the thickness of the tongue which is inserted in the connection device.
Par nature, la connexion d'un système de distribution électrique de type barre de pontage à fourches ou à languettes impose un enfichage simultané ou quasi-simultané de plusieurs languettes dans les connecteurs de raccordement d'une rangée d'appareils modulaires électriques disposés côte à côte sur un même rail normalisé. Cet enfichage simultané implique de vaincre la résistance de plusieurs lames ressort en même temps, ce qui peut s'avérer problématique car les forces de contact qui sont conférées à chaque lame ressort sont loin d'être négligeables, et qu'elles s'exercent au surplus à peu près perpendiculairement aux forces d'enfichage.By nature, the connection of a power distribution system of the type of bridging bar or tongues requires simultaneous or almost simultaneous insertion of several tongues in the connectors of a row of modular electrical devices arranged side by side. coast on the same standardized rail. This simultaneous insertion involves overcoming the resistance of several spring blades at the same time, which can be problematic because the contact forces that are imparted to each blade spring are far from negligible, and they are exerted at the same time. surplus approximately perpendicular to the insertion forces.
Le problème consiste en l'occurrence à réduire l'effort d'enfichage sans altérer les caractéristiques du ressort, et notamment la force de contact qu'il peut développer une fois la languette de la barre de pontage enfichée en appui sur la borne. Jusqu'ici, lorsque ce type de problème se posait, le remède consistait à graisser la zone d'enfichage et de contact, sans altérer le dispositif de connexion proprement dit.The problem consists in the occurrence of reducing the insertion force without altering the characteristics of the spring, and in particular the contact force that it can develop once the tongue of the bridging bar plugged against the terminal. Until now, when this type of problem arose, the remedy was to grease the plugging area and contact, without altering the connection device itself.
La présente invention se propose de mettre en oeuvre des solutions dans lesquelles le dispositif de connexion a été conçu ab initio pour répondre à ce problème.The present invention proposes to implement solutions in which the connection device was designed ab initio to respond to this problem.
A titre essentiel, ce dispositif comporte des moyens pour maintenir au moins une lame ressort à distance de la surface conductrice.Essentially, this device comprises means for maintaining at least one blade spring at a distance from the conductive surface.
Cette solution consiste en fait à prépositionner une ou plusieurs lames ressort du dispositif de connexion dans une position que l'on peut qualifier de prête à l'enfichage. Ce prépositionnement permet de limiter la course du ressort lors de l'enfichage de la barre, et de garantir par conséquent une progressivité de l'effort. Cette progressivité procure à l'installateur une facilité d'enfichage lorsqu'il met en oeuvre ce type de dispositif.This solution consists in fact in prepositioning one or more spring blades of the connection device in a position that can be described as ready for insertion. This prepositioning makes it possible to limit the stroke of the spring during the insertion of the bar, and thus to guarantee a progressivity of the effort. This progressivity gives the installer ease of insertion when implementing this type of device.
Selon une variante de mise en oeuvre du dispositif de l'invention, au moins une lame ressort comporte un ergot latéral pouvant se déplacer dans une fenêtre pratiquée dans une paroi orientée parallèlement à la direction de déflexion de la lame ressort, ladite fenêtre étant positionnée et dimensionnée de sorte que quand l'ergot, sous l'effet des efforts élastiques, est en butée contre un de ses bord, la lame est maintenue à distance de la surface conductrice.According to an alternative embodiment of the device of the invention, at least one leaf spring has a lateral lug that can move in a window formed in a wall oriented parallel to the direction of deflection of the leaf spring, said window being positioned and dimensioned so that when the lug, under the effect of the elastic forces, abuts against one of its edge, the blade is kept away from the conductive surface.
En fait, au moins l'une des lames est ainsi accrochée à une certaine distance de la surface conductrice, le niveau d'accrochage correspondant à une hauteur de passage prédéfinie du conducteur à connecter qui garantit la réduction de l'effort d'enfichage. Lors de l'enfichage de la languette de la barre de pontage, chaque lame ressort se libère de son niveau de prépositionnement et peut assurer toute la force de contact. Le prépositionnement conserve en effet intacte la force de contact qui est développée par la lame ressort.In fact, at least one of the blades is thus hooked at a distance from the conductive surface, the attachment level corresponding to a predefined passage height of the conductor to be connected which guarantees the reduction of the insertion force. When inserting the tongue of the bridging bar, each spring blade is released from its prepositioning level and can ensure all the contact force. The prepositioning keeps intact the contact force that is developed by the leaf spring.
Selon une possibilité, la paroi dans laquelle est pratiquée la fenêtre est d'une seule pièce avec une paroi dans laquelle est réalisée et à partir de laquelle se développe au moins une lame ressort du dispositif de l'invention.According to one possibility, the wall in which the window is made is in one piece with a wall in which is produced and from which develops at least one spring blade of the device of the invention.
Plus précisément encore, la paroi comportant au moins une lame ressort se prolonge par deux parois latérales parallèles, dont l'une au moins est munie de ladite fenêtre, ces parois définissant un volume dans lequel la ou les lames ressort se développent au moins partiellement, lesdites parois latérales étant solidaires ou d'une seule pièce avec la surface conductrice.More precisely still, the wall comprising at least one spring blade is extended by two parallel side walls, at least one of which is provided with said window, these walls defining a volume in which the at least one leaf spring develops at least partially, said sidewalls being integral or integral with the conductive surface.
Le dispositif de connexion est alors réalisé sans composant additionnel par rapport à ses devanciers. La solution est de plus standardisable, facile à mettre en oeuvre, et elle permet enfin de limiter la contrainte de contact au moment de l'enfichage avec une marge de calibration qui dépend de l'utilisation qui en sera faite ultérieurement. Cette calibration, réalisée en phase de fabrication du dispositif de l'invention, permet d'ajuster la force d'enfichage en fonction des exigences du marché ou du calibre du produit dans lequel le dispositif de l'invention est intégré, par exemple un appareil modulaire de type disjoncteur.The connection device is then made without additional component compared to its predecessors. The solution is moreover standardizable, easy to implement, and it finally makes it possible to limit the contact stress at the time of insertion with a calibration margin which depends on the use that will be made subsequently. This calibration, carried out in the manufacturing phase of the device of the invention, makes it possible to adjust the insertion force according to the market requirements or the caliber of the product in which the device of the invention is integrated, for example a device modular type circuit breaker.
Elle consiste à moduler les dimensions de la fenêtre en fonction de la distance à laquelle on veut positionner la lame ressort par rapport à la borne conductrice, ou à ne pas prévoir de liaison ergot-fenêtre pour toutes les lames ressort du dispositif de connexion.It consists in modulating the dimensions of the window according to the distance at which the spring blade is to be positioned relative to the conductive terminal, or not to provide a pin-window connection for all spring blades of the connection device.
Ainsi, selon une possibilité, le dispositif de l'invention peut comporter deux lames élastiques parallèles ménageant un espace entre elles, une seule lame comportant un ergot coopérant avec une fenêtre de la paroi latérale adjacente.Thus, according to one possibility, the device of the invention may comprise two parallel elastic blades leaving a space between them, a single blade having a lug cooperating with a window of the adjacent side wall.
Comme on le verra plus en détail dans la suite, c'est notamment le type de configuration qui est utilisé lorsque deux connecteurs sont superposés, par exemple un dispositif à cage et vis traditionnel surmonté d'une coiffe intégrant le ou les lames ressort. Dans cette hypothèse, l'espace ménagé entre les lames élastiques permet le passage de la vis, dont la tête doit être accessible depuis la façade du produit.As will be seen in more detail later, it is particularly the type of configuration that is used when two connectors are superimposed, for example a cage device and traditional screw surmounted by a cap incorporating the spring blade or blades. In this case, the space between the elastic blades allows the passage of the screw, whose head must be accessible from the front of the product.
L'expérience a montré que l'enfichage des languettes fourchées des barres de pontage est grandement facilité même si une seule des lames élastiques est munie du perfectionnement de l'invention, la progressivité de l'effort d'enfichage étant déjà largement améliorée.Experience has shown that the plugging of the forked tabs bridging is greatly facilitated even if only one of the elastic blades is provided with the improvement of the invention, the progressivity of the plugging effort is already greatly improved.
Selon une alternative à cette première configuration, les moyens de maintien de la lame à distance de la surface peuvent consister en une béquille réalisée à partir de ladite lame, par découpe et pliage d'une portion de celle-ci, l'extrémité libre de cette portion pliée prenant appui sur la surface conductrice.According to an alternative to this first configuration, the means for holding the blade away from the surface may consist of a stand made from said blade, by cutting and folding a portion thereof, the free end of this folded portion bearing on the conductive surface.
Cette béquille procure en fait un appui supplémentaire qui permet de relever la ou les lames ressort pour la ou les mettre dans une position prête à l'enfichage. Cet appui doit bien entendu être réalisé hors de la zone de passage de la lamelle enfichée.This stand provides in fact an additional support that can raise the leaf spring or to put them in a position ready to plug. This support must of course be made outside the passage area of the inserted leaflet.
De préférence, la portion de lame formant béquille est découpée et pliée au niveau de l'extrémité libre de la lame ressort.Preferably, the leg portion forming a crutch is cut and folded at the free end of the leaf spring.
Cette caractéristique est notamment favorable en terme de réalisation industrielle, puisqu'elle facilite les opérations de découpage et de pliage.This characteristic is particularly favorable in terms of industrial production, since it facilitates the cutting and folding operations.
Cette solution, comme la précédente, ne nécessite pas l'utilisation de composants additionnels pour l'invention et elle permet à l'utilisateur de s'affranchir de l'emploi de produits de type graisse ou huile, etc. Selon la forme ou les dimensions données à la béquille, le calibrage de l'effort d'enfichage est également aisé avec cette solution.This solution, like the previous one, does not require the use of additional components for the invention and it allows the user to overcome the use of grease or oil type products, etc. Depending on the shape or dimensions given to the stand, the calibration of the insertion force is also easy with this solution.
Lorsque la lame ressort comporte deux branches parallèles, ménageant un espace entre elles, celles-ci sont reliées par une béquille centrale, qui se positionne après pliage à la périphérie dudit espace.When the leaf spring has two parallel branches, providing a space between them, they are connected by a central stand, which is positioned after folding at the periphery of said space.
Dans l'hypothèse où le dispositif de l'invention comporte deux lames élastiques parallèles distinctes, dotées chacune d'une béquille et ménageant également un espace entre elles, les portions formant béquille sont alors disposées adjacentes et toujours, après pliage, à la périphérie de cet espace.In the event that the device of the invention comprises two separate parallel spring blades, each having a crutch and also providing a space between them, the crutch portions are then disposed adjacent and always, after folding, on the periphery of this space.
Dans les deux cas, de préférence, chaque béquille est orientée sensiblement perpendiculairement à la surface conductrice. De préférence encore, l'extrémité des béquilles au contact de la surface conductrice est recourbée.In both cases, preferably, each stand is oriented substantially perpendicularly to the conductive surface. More preferably, the end of the stands in contact with the conductive surface is bent.
Ces caractéristiques configurationnelles visent à optimiser l'usage de cette béquille, et à lui permettre de réaliser sa fonction dans les meilleures conditions.These configurational characteristics aim to optimize the use of this crutch, and to enable it to perform its function under the best conditions.
Selon une autre alternative encore, les moyens de maintien de la lame ressort à distance de la surface conductrice consistent en une cale calibrée maintenue entre la lame et la surface conductrice par l'effort élastique exercé par ladite lame, ladite cale étant expulsée lors de l'introduction du conducteur qui la chasse devant lui.According to yet another alternative, the means for holding the blade spring away from the conductive surface consist of a calibrated wedge held between the blade and the conductive surface by the elastic force exerted by said blade, said wedge being expelled during the introduction of the driver chasing it in front of him.
Cette variante nécessite la mise en place d'une pièce intermédiaire logée entre la lame ressort et la surface conductrice et calibrée au gré de l'utilisateur. Sa forme doit lui permettre d'assurer le calage de la lame, mais aussi de réduire le frottement pour déterminer, au final, l'effort d'enfichage qui est nécessaire.This variant requires the establishment of an intermediate piece housed between the spring blade and the conductive surface and calibrated at the discretion of the user. Its shape It must allow it to ensure the setting of the blade, but also to reduce the friction to determine, in the end, the insertion force that is necessary.
Par rapport aux solutions précédentes, celle-ci permet un calibrage de l'effort d'enfichage qui est modulable même lorsque l'appareil destiné à contenir le dispositif de connexion a déjà été fabriqué.Compared to the previous solutions, it allows a calibration of the plugging force which is adjustable even when the device for containing the connection device has already been manufactured.
Il à noter que dans toutes les variantes de l'invention, la précontrainte initiale qui est conférée à la ou aux lames ressort maintenue(s) à distance de la surface conductrice est maîtrisée , et n'a pas d'effet particulier sur le fonctionnement ultérieur du dispositif de connexion.It should be noted that in all the variants of the invention, the initial prestress which is imparted to the spring blade (s) maintained (s) at a distance from the conductive surface is controlled, and has no particular effect on the operation. subsequent connection device.
Selon une possibilité, le profil de la cale est prévu pour conférer à la lame ressort une orientation lui permettant de faciliter l'insertion du conducteur, et il présente de plus une surface frontale d'allure concave prévue pour recevoir l'extrémité libre du conducteur en cours d'insertion.According to one possibility, the wedge profile is provided to give the spring blade an orientation enabling it to facilitate the insertion of the conductor, and it also has a concave front surface designed to receive the free end of the conductor in the course of insertion.
Outre sa fonction principale visant à maintenir la lame ressort à distance de la surface conductrice, la cale de l'invention a donc une fonction secondaire que l'on peut presque qualifier de guidage à l'introduction des conducteurs.In addition to its main function of keeping the blade spring away from the conductive surface, the wedge of the invention therefore has a secondary function that can almost be described as guiding the introduction of conductors.
De préférence, cette cale est symétrique par rapport à un plan médian parallèle à la surface conductrice, en vue d'optimiser son utilisation. Dans le cas d'un appareil électrique modulaire, cette cale amovible provisoire peut d'ailleurs être mise en place sur le produit fini, avec le conditionnement.Preferably, this wedge is symmetrical with respect to a median plane parallel to the conductive surface, in order to optimize its use. In the case of a modular electrical appliance, this temporary removable wedge can also be put in place on the finished product, with packaging.
Selon une autre alternative encore, les moyens de maintien de la lame à distance de la surface conductrice consistent en un prolongement de l'extrémité libre de ladite lame reposant à proximité d'un bord de cette surface de sorte qu'à l'enfichage du conducteur, ladite extrémité libre soit repoussée hors de la surface conductrice et la lame sollicitée élastiquement au contact du conducteur.According to yet another alternative, the means for holding the blade away from the conductive surface consist of an extension of the free end of said blade resting close to an edge of this surface so that at the insertion of the conductive, said free end is pushed out of the conductive surface and the elastically biased blade in contact with the conductor.
Il s'agit d'une sorte de "guillotine", activée en fin de course lors de l'enfichage de la languette de la barre de pontage. Cette variante, qui permet de dégager totalement la zone d'enfichage, limite par conséquent au maximum l'effort d'enfichage. Cette solution permet en outre d'optimiser la force de contact une fois la barre enfichée, c'est-à-dire lorsque la "guillotine" a été mise en action.This is a kind of "guillotine" activated at the end of the race when inserting the tongue of the bridging bar. This variant, which allows to completely clear the plugging area, therefore limits the maximum insertion effort. This solution also makes it possible to optimize the contact force once the bar is plugged in, that is to say when the "guillotine" has been put into action.
Selon une géométrie possible, l'extrémité de la lame ressort est par exemple prolongée par une boucle ouverte vers la surface conductrice suivie d'une portion rectiligne orientée sensiblement verticalement et dont le bout est au contact de ladite surface.According to a possible geometry, the end of the spring blade is for example extended by a loop open towards the conductive surface followed by a rectilinear portion oriented substantially vertically and whose end is in contact with said surface.
Comme cela a été évoqué auparavant, le dispositif de connexion de l'invention peut être composé d'une coiffe comportant une paroi supérieure de laquelle se développent deux lames ressort jumelles recourbées entre deux parois latérales vers une portion plane d'une borne conductrice parallèle à la paroi supérieure et à laquelle sont fixées lesdites parois latérales.As has been mentioned before, the connection device of the invention may be composed of a cap having an upper wall of which develop two twin spring blades curved between two side walls to a flat portion of a conductive terminal parallel to the upper wall and to which are fixed said side walls.
Cette configuration est particulièrement adaptée lorsque la borne coopère avec une cage disposée sous la coiffe et avec une vis de serrage des conducteurs dans la cage dont la tige passe entre les lames ressort jumelles et dont la tête est disposée au-dessus de la paroi supérieure de la coiffe.This configuration is particularly suitable when the terminal cooperates with a cage disposed under the cap and with a screw clamping conductors in the cage whose rod passes between the twin spring blades and whose head is disposed above the upper wall of The hairdo.
Cette superposition est notamment appliquée à des appareils électriques modulaires du type disjoncteur, interrupteur différentiel, etc... qui constituent également l'invention lorsqu'ils en sont munis.This superposition is particularly applied to modular electrical devices of the type circuit breaker, differential switch, etc ... which also constitute the invention when equipped.

En référence à la figure 1, le dispositif de connexion de l'invention se compose principalement d'une lame ressort (1) rappelée élastiquement en direction de la surface conductrice d'une borne (2), de manière à enserrer un conducteur (non représenté). Ce conducteur est enfiché dans la direction montrée par la flèche F. Dans la configuration particulière qui est représentée en figures 1 et 2, le dispositif de connexion surmonte en fait une borne à cage (3) et vis (4) traditionnelles, et comporte à titre essentiel une paroi supérieure (6) à partir de laquelle se développent les lames ressort (1, 1'), qui sont recourbées vers l'intérieur de la coiffe (5) ainsi constituée, laquelle est délimitée par des parois latérales (7 et 8) qui sont fixées sur la borne (2).With reference to FIG. 1, the connection device of the invention mainly consists of a spring blade (1) resiliently biased towards the conductive surface of a terminal (2), so as to grip a conductor (no represent). This conductor is plugged in the direction shown by the arrow F. In the particular configuration shown in FIGS. 1 and 2, the connection device in fact overcomes a conventional cage terminal (3) and screw (4), and comprises essential title an upper wall (6) from which develop the leaf spring (1, 1 '), which are curved inwardly of the cap (5) thus formed, which is delimited by side walls (7 and 8) which are fixed on the terminal (2).
Il existe déjà de telles structures de connexion comportant un connecteur traditionnel à cage et vis et un connecteur à lames superposées. Les lames ressort recourbées y sont telles que leurs portions inférieures arrondies (20) sont au contact de la surface supérieure de la borne conductrice (2). L'apport de l'invention se situe à ce niveau, puisque lesdites lames ressort (1, 1') subissent une précontrainte supplémentaire pour les maintenir à distance de ladite borne conductrice (2). Dans la version de l'invention illustrée aux figures 1 et 2, les moyens de maintien à distance consistent d'une part en une ouverture (9) pratiquée dans l'une des parois latérales (7) de la coiffe (5), ouverture (9) dans laquelle vient se loger un ergot (10) qui dépasse d'un chant latéral de l'extrémité libre de la lame ressort (1) (voir en figure 2).There already exist such connection structures comprising a traditional connector with cage and screw and a connector with superposed blades. The curved spring blades are such that their rounded lower portions (20) are in contact with the upper surface of the conductive terminal (2). The contribution of the invention lies at this level, since said spring blades (1, 1 ') undergo a additional prestressing to keep them away from said conductive terminal (2). In the version of the invention illustrated in FIGS. 1 and 2, the remote holding means consist on the one hand of an opening (9) made in one of the side walls (7) of the cap (5), opening (9) in which is housed a lug (10) protruding from a side edge of the free end of the leaf spring (1) (see Figure 2).
La lame ressort (1) est donc forcée de prendre la position qui apparaît en figure 1, à distance de la borne (2). Cette configuration diminue assez sensiblement l'effort d'enfichage du conducteur externe, en l'occurrence par exemple une fourche d'une barre de pontage.The leaf spring (1) is forced to take the position shown in Figure 1, away from the terminal (2). This configuration substantially decreases the effort of plugging the external conductor, in this case for example a fork of a bridge bar.
La configuration montrée aux figures 3 et 4 vise le même objectif. Dans cette hypothèse, les parois latérales (7, 8) de la coiffe (5) ne sont pas utilisées. En l'occurrence, les extrémités libres de chaque lame ressort (1, 1') sont reliées par une béquille (11) obtenue par découpage et pliage d'un tronçon central.The configuration shown in Figures 3 and 4 is for the same purpose. In this case, the side walls (7, 8) of the cap (5) are not used. In this case, the free ends of each leaf spring (1, 1 ') are connected by a stand (11) obtained by cutting and folding a central section.
Le tronçon central est partiellement désolidarisé des branches (1, 1') par des découpes longitudinales sur la presque totalité de sa longueur commune avec lesdites branches (1, 1'). La portion centrale est ensuite pliée de façon à la rendre d'une part sensiblement perpendiculaire à la surface conductrice de la borne (2), et pour recourber d'autre part son extrémité pour qu'elle repose sur un arrondi.The central section is partially disengaged from the branches (1, 1 ') by longitudinal cuts over almost all of its length common with said branches (1, 1'). The central portion is then folded so as to make it on the one hand substantially perpendicular to the conductive surface of the terminal (2), and to curl on the other hand its end so that it rests on a rounded.
Il est à noter que, dans la configuration qui est représentée aux figures 3 et 4, la béquille n'interfère pas, après pliage, avec l'espace dans lequel doit s'insérer la tige de la vis (4) (non représentée). La distance qui sépare la surface conductrice de la borne (2) et la portion inférieure recourbée (20) des lames ressort (1, 1') est sensiblement identique à celle qui est maintenue dans la configuration montrée aux figures 1 et 2.It should be noted that, in the configuration shown in FIGS. 3 and 4, the stand does not interfere, after folding, with the space in which the screw shank (4) must be inserted (not shown). . The distance between the conductive surface of the terminal (2) and the curved lower portion (20) of the leaf spring (1, 1 ') is substantially identical to that maintained in the configuration shown in Figures 1 and 2.
Cette distance est aisée à faire varier, en changeant la position de la courbure inférieure de la béquille (11), ou en allongeant cette dernière, etc. Il en va de même pour la solution des figures 1 et 2, dans laquelle la hauteur de la fenêtre détermine en fait l'espace résiduel maintenu entre la lame (1) et la borne conductrice (2).This distance is easy to vary, by changing the position of the lower curvature of the stand (11), or by lengthening the latter, etc. The same goes for the solution of FIGS. 1 and 2, in which the height of the window determines in fact the residual space maintained between the blade (1) and the conductive terminal (2).
Il est également possible de tronçonner la béquille (11) centrale en deux béquilles adjacentes. Dans ce cas, chaque lame ressort (1, 1') présente, sur une portion au niveau de son extrémité libre, une largeur qui lui permet d'être immédiatement adjacente à l'autre lame ressort (1', 1).It is also possible to cut the central stand (11) into two adjacent crutches. In this case, each blade spring (1, 1 ') has, on a portion at its free end, a width that allows it to be immediately adjacent to the other leaf spring (1', 1).
Les deux béquilles (11, 11') résultant de cette double opération sont également situées au centre de la coiffe, et n'interférent pas avec l'espace central de passage de la vis.The two crutches (11, 11 ') resulting from this double operation are also located in the center of the cap, and do not interfere with the central passage space of the screw.
La version de la figure 5 diffère des deux précédentes en ce qu'elle comporte un élément (12) amovible, une cale (12) qui s'insère provisoirement entre la lame ressort (1) et la borne (2). Cette cale (12) est destinée à être repoussée par l'extrémité du conducteur (c) telle qu'elle apparaît sur la droite de la figure. Ainsi, la cale comporte une surface frontale (13) légèrement arrondie, de manière à "guider" l'extrémité du conducteur (c).The version of Figure 5 differs from the previous two in that it comprises a member (12) removable, a shim (12) which is inserted temporarily between the leaf spring (1) and the terminal (2). This wedge (12) is intended to be pushed by the end of the conductor (c) as it appears on the right of the figure. Thus, the wedge has a slightly rounded front surface (13) so as to "guide" the end of the conductor (c).
La forme de cette cale est symétrique, afin qu'elle puisse être introduite, surface concave (13) évidemment tournée vers l'extérieur du dispositif de raccordement, dans deux sens différents. Pour que la cale (12) puisse être coincée efficacement, elle comporte notamment deux autres surfaces bombées concaves, sur ses faces latérales supérieure et inférieure, qui lui permettent de recevoir la surface inférieure (20) recourbée de la lame ressort (1).The shape of this wedge is symmetrical, so that it can be introduced, concave surface (13) obviously facing outwardly of the connecting device, in two different directions. In order for the wedge (12) to be wedged effectively, it comprises in particular two other concave curved surfaces, on its upper and lower lateral faces, which enable it to receive the lower surface (20) curved with the spring blade (1).
Lorsque l'extrémité du conducteur arrive au niveau de la surface (13), l'utilisateur n'a pas encore rencontré de résistance, car l'espace entre le reste de la lame ressort (1) et la borne conductrice (2) est à cet endroit de dimension supérieure à la largeur ou au diamètre du conducteur. L'extrémité du conducteur (c) repousse progressivement la cale (12) jusqu'à ce que la force de la lame s'applique sur le conducteur : la cale (12) est alors libérée, et peut se loger dans un logement prévu à cet effet, par exemple relié au sous-ensemble borne/lame ressort, qui garantit sa position après l'enfichage du conducteur.When the end of the conductor reaches the level of the surface (13), the user has not yet encountered any resistance, because the space between the rest of the leaf spring (1) and the conductive terminal (2) is at this point of dimension greater than the width or the diameter of the conductor. The end of the conductor (c) gradually pushes the shim (12) until the force of the blade is applied to the conductor: the shim (12) is then released, and can be housed in a housing provided for this effect, for example connected to the subassembly terminal / leaf spring, which ensures its position after plugging the driver.
La version qui est représentée en figure 6 utilise un principe similaire à la solution de la figure 5, mais sans composant additionnel, c'est-à-dire sans cale. Le maintien de la surface inférieure (20) recourbée de la lame ressort (1) à distance de la borne conductrice (2) est ici réalisée par un tronçon d'extrémité (13) de ladite lame (1), orientée sensiblement verticalement de manière que son extrémité libre soit au contact de ladite borne (2) pour une distance entre cette dernière et la surface inférieure recourbée (20) permettant le passage du conducteur (c). Le tronçon (13), rectiligne et sensiblement orienté verticalement, est en outre disposé à proximité d'un chant bordant la borne conductrice (2), comme cela est représenté en trait plein. Lorsque l'extrémité libre du conducteur repousse cette portion verticale (13), au moment où l'utilisateur procède à l'enfichage dudit conducteur (c), cette portion se retrouve rapidement sans appui et est, du fait de la précontrainte de la lame ressort (1), rappelée vers le bas. La lame ressort (1) prend alors la forme qui apparaît en trait pointillé. Dans ce cas, la surface inférieure (20) recourbée de ladite lame (1) vient au contact du conducteur (c) qu'elle emprisonne.The version shown in Figure 6 uses a principle similar to the solution of Figure 5, but without additional component, that is to say without wedge. Maintaining the curved lower surface (20) of the leaf spring (1) away from the conductive terminal (2) is here formed by an end section (13) of said blade (1), oriented substantially vertically so its free end is in contact with said terminal (2) for a distance between the latter and the curved lower surface (20) allowing the passage of the conductor (c). The section (13), rectilinear and substantially vertically oriented, is further disposed near a edge bordering the conductive terminal (2), as shown in solid lines. When the free end of the driver pushes this vertical portion (13), at the moment when the user proceeds to the plugging of said conductor (c), this portion is quickly found without support and is, because of the prestressing of the blade spring (1), pushed back down. The spring blade (1) then takes the form which appears in dashed line. In this case, the lower surface (20) curved of said blade (1) comes into contact with the driver (c) that it traps.
