Description

La présente invention a trait à un connecteur électrique à ressort à cage, du type constitué d'une lame ressort formant une boucle dont une des extrémités est en général fixée sur une borne électrique sous forme d'une plaque, laquelle est engagée dans un orifice pratiqué dans l'autre extrémité de la lame. A l'état de repos, la borne fixée à la lame ressort repose sur le chant de l'orifice le plus proche de l'extrémité de la lame.The present invention relates to a spring-loaded electrical connector with cage, of the type consisting of a spring leaf forming a loop, one of which of the ends is generally fixed on an electrical terminal in the form a plate, which is engaged in an opening in the other end of the blade. In the idle state, the terminal attached to the leaf spring rests on the edge of the hole closest to the end of the blade.

Pour réaliser la connexion d'un conducteur, il faut contraindre la lame ressort, de telle sorte que l'orifice, qui ne s'étend en position stable que d'un seul côté de la borne permute d'un côté à l'autre de celle-ci. On introduit alors le conducteur dans l'orifice ainsi permuté par contrainte, et on relâche l'action sur la lame ressort, de sorte que le conducteur se trouve coincé entre la borne et un chant de l'orifice rappelé en direction de cette dernière.To make the connection of a conductor, you must constrain the blade spring, so that the opening, which only extends in a stable position on one side of the terminal swaps from one side to the other thereof. We then introduces the conductor into the orifice thus permuted by constraint, and the action is released on the leaf spring, so that the conductor found wedged between the terminal and a song of the hole recalled towards of the latter.

Ce type de configuration est bien connu et a fait l'objet de multiples variantes, visant à l'adapter à un grand nombre d'applications. L'invention a plus particulièrement pour objectif d'appliquer ce type de connecteur à des appareils électriques modulaires de type disjoncteur.This type of configuration is well known and has been the subject of multiple variants, aimed at adapting it to a large number of applications. The invention more particularly aims to apply this type of connector to modular electrical devices such as a circuit breaker.

Pour ces appareils, la capacité de connexion est un facteur important. Ainsi, il doit être possible de connecter des conducteurs de calibres différents, ou encore de procéder au raccordement de plusieurs conducteurs à un même connecteur, etc. Or, l'une des limitations que présentent les connecteurs à ressort à cage réside souvent dans la surface de l'orifice, sur laquelle est en fait basée la configuration en boucle précitée.For these devices, the connection capacity is an important factor. Thus, it must be possible to connect gauge conductors or to connect several conductors with the same connector, etc. One of the limitations that have cage spring connectors often resides in the surface of the orifice, on which the above-mentioned loop configuration is in fact based.

L'augmentation de cette surface conduit de fait à une augmentation de la largeur qui devient vite problématique dans une application de type appareil électrique modulaire. L'un des impératifs essentiels de la conception desdits appareils réside en effet dans l'optimisation de la gestion de l'espace intérieur à leur boítier. Or, il est nécessaire dans nombre d'applications de permettre deux entrées de conducteur(s) adjacentes disposées, au même niveau dans la façade latérale d'un tel appareil. Dans ce cas, l'utilisation des bornes à ressort à cage précitées pose problème car la largeur normalisée de ces appareils ne suffit pas à permettre leur positionnement dans la largeur, sauf à restreindre la surface de l'orifice, ce qui est impossible car la surface des ouvertures d'entrée ne doit pas être trop étroite en raison des contraintes pratiques d'utilisation de ces appareils.The increase in this area in fact leads to an increase in width which quickly becomes problematic in an electrical appliance type application Modular. One of the essential requirements for the design of these devices is in fact in the optimization of the management of the interior space in their case. But, he is necessary in many applications to allow two inputs of adjacent conductor (s) arranged at the same level in the side façade of a such device. In this case, the use of the aforementioned cage spring terminals poses problem because the standardized width of these devices is not sufficient to allow their positioning in width, except to restrict the surface of the orifice, which is impossible because the surface of the inlet openings must not be too narrow in because of the practical constraints of using these devices.

C'est le problème que se propose de résoudre la présente invention.This is the problem which the present invention proposes to solve.

A cet effet, le connecteur proposé, formé d'une plaque constituant une borne électrique pour un appareil équipé dudit connecteur, à laquelle est fixé au moins un ressort à cage prenant la forme d'une lame en forme de boucle comportant une première portion d'extrémité d'allure plane solidarisée à la borne, suivie d'une portion inclinée s'en écartant, puis d'une portion terminale d'allure plane orientée selon une direction sensiblement perpendiculaire à la borne, qui comporte une fenêtre entourant cette dernière, le déplacement relatif élastique borne / lame ressort étant limité par des chants de ladite fenêtre orientés parallèlement à la borne, se caractérise à titre essentiel en ce que la portion terminale est constituée d'une plaque plane indépendante du reste de la lame, fixée à cette dernière dans sa partie distale de la borne.For this purpose, the proposed connector, formed of a plate constituting a terminal electrical for a device equipped with said connector, to which is fixed at least one cage spring taking the form of a loop-shaped blade comprising a first end portion of flat appearance secured to the terminal, followed by a inclined portion deviating from it, then of a terminal portion of planar aspect oriented in a direction substantially perpendicular to the terminal, which includes a window surrounding the latter, the relative elastic displacement terminal / blade spring being limited by edges of said window oriented parallel to the terminal, is essentially characterized in that the terminal portion is constituted a flat plate independent of the rest of the blade, fixed to the latter in its distal part of the terminal.

L'avantage principal de cette structure est qu'elle permet d'aboutir à une compacité bien plus grande de ces systèmes de raccordement à ressort à cage, autorisant notamment leur application à des appareils électriques modulaires dans de bien meilleures conditions. La plaque terminale permet ainsi d'augmenter la largeur de l'ouverture, dans une proportion que l'on ne pourrait pas obtenir si l'orifice était directement pratiqué dans la lame ressort. Cette largeur peut alors facilement atteindre la largeur du ressort.The main advantage of this structure is that it leads to a much greater compactness of these cage spring connection systems, authorizing in particular their application to modular electrical devices in much better conditions. The end plate thus increases the width of the opening, in a proportion that could not be obtained if the hole was made directly in the leaf spring. This width can then easily reach the width of the spring.

Cette plaque terminale est en outre intéressante du point de vue de la fabrication car elle facilite l'assemblage du connecteur dans l'appareil modulaire. Comme on le verra dans la suite, dans une utilisation à plusieurs connecteurs de front, un gain de place en largeur est notamment obtenu par décalage desdites plaques selon une direction perpendiculaire à leur plan principal. This end plate is also interesting from the point of view of the manufacturing because it facilitates the assembly of the connector in the modular device. As will be seen below, in a use with several connectors of forehead, a space saving in width is notably obtained by shifting said plates in a direction perpendicular to their main plane.

Selon une possibilité, la fixation de la lame ressort à la plaque terminale est réalisée par sertissage. Il est bien entendu possible de mettre en oeuvre d'autres possibilités de fixation, le sertissage présentant cependant l'avantage de pouvoir être réalisé industriellement simplement et à faible coût.According to one possibility, the fixing of the leaf spring to the end plate is produced by crimping. It is of course possible to implement other fixing possibilities, crimping, however, has the advantage of being able be produced industrially simply and at low cost.

L'extrémité de la borne dépassant de la fenêtre de la plaque terminale, à l'opposé de la lame ressort, comporte un bossage saillant de la face de ladite borne opposée à celle sur laquelle est fixée la lame.The end of the terminal protruding from the window of the terminal plate, at the opposite of the leaf spring, has a projection projecting from the face of said terminal opposite to that on which the blade is fixed.

Cette caractéristique permet une meilleure tenue du conducteur, et plaque notamment ce dernier contre la borne, fiabilisant ainsi la connexion électrique.This characteristic allows a better behavior of the conductor, and plate in particular the latter against the terminal, thus making the electrical connection more reliable.

De même, selon une possibilité de construction, la fixation de la lame ressort à la borne est réalisée au moyen d'un relief d'allure cylindrique dépassant de la borne et fixé dans un orifice de la lame.Similarly, according to a construction possibility, the fixing of the blade comes out at the bollard is produced by means of a relief of cylindrical appearance projecting from the bollard and fixed in a hole in the blade.

Pour des raisons qui seront explicitées plus loin dans la description, et qui tiennent à l'application particulière du connecteur de l'invention aux appareils électriques modulaires, la borne peut comporter une excroissance, disposée à son extrémité distale de celle qui coopère avec la plaque terminale, orientée sensiblement perpendiculairement au plan général de la borne.For reasons which will be explained later in the description, and which relate to the particular application of the connector of the invention to devices modular electrical, the terminal may include a projection, arranged at its distal end of that which cooperates with the end plate, oriented substantially perpendicular to the general plane of the terminal.

Cette portion permet en fait de faciliter les tests de vérification de la qualité du raccordement.This portion actually makes it possible to facilitate the verification tests of the quality of the connection.

Dans une configuration à deux points de raccordement, la borne peut comporter deux ensembles à lame ressort et plaque terminale, les plaques terminales étant alors décalées perpendiculairement à leurs plans moyens pour que les chants latéraux des lames ressorts puissent être en contact, l'extrémité de la borne coopérant avec les fenêtres des plaques terminales étant alors séparée en deux branches dont les extrémités sont également décalées.In a configuration with two connection points, the terminal can include two sets with leaf spring and end plate, the end plates being then shifted perpendicular to their mean planes so that the edges side of the leaf springs can be in contact, the end of the terminal cooperating with the windows of the end plates then being separated in two branches whose ends are also offset.

Cette configuration décalée permet, comme on l'a déjà mentionné, un gain de place en largeur qui est appréciable dans l'optique de l'intégration du système à des appareils électriques modulaires classiques.This offset configuration allows, as already mentioned, a gain of place in width which is appreciable in view of the integration of the system to classic modular electrical appliances.

L'invention concerne également ces appareils, lorsqu'ils comportent au moins un connecteur tel que décrit ci-dessus, au moins un connecteur étant alors disposé dans au moins un logement du boítier de l'appareil situé derrière une face latérale dudit boítier, un nombre d'orifices correspondant au nombre de plaques terminales étant pratiqué dans chaque face latérale sous l'emplacement fixe de chaque borne.The invention also relates to these devices, when they comprise at least one connector as described above, at least one connector then being arranged in at least one housing of the device housing located behind a side face of said housing, a number of orifices corresponding to the number of end plates being practiced in each side face under the fixed location of each terminal.

Lorsqu'au moins deux lames ressort sont disposées dans la largeur de l'appareil, la configuration à plaque terminale indépendante présente les avantages précités et principalement la possibilité de décalage sans obérer la capacité de connexion. Cette configuration peut bien entendu être utilisée également dans une hypothèse à une seule lame ressort, l'existence de la plaque terminale présentant dans ce cas l'avantage d'offrir une capacité de raccordement compatible avec les exigences en vigueur pour les appareils électriques modulaires. En outre, la facilité d'assemblage du système reste vérifiée dans cette hypothèse.When at least two leaf springs are arranged across the width of device, independent end plate configuration has the advantages aforementioned and mainly the possibility of shifting without hampering the ability to connection. This configuration can of course also be used in a hypothesis with only one leaf spring, the existence of the end plate presenting in this case the advantage of offering a connection capacity compatible with the applicable requirements for modular electrical devices. In addition, the ease system assembly remains verified in this hypothesis.

Selon une possibilité configurationnelle, les orifices pratiqués dans la face latérale de connexion peuvent être munis d'un canon de guidage. La fonction d'un tel canon est de faciliter l'insertion des conducteurs dans un côté qui est en général moins accessible à l'utilisateur, car ne lui faisant pas face.According to a configuration possibility, the orifices made in the lateral face connection can be fitted with a guide bush. The function of such a cannon is to facilitate the insertion of the conductors in a side which is generally less accessible to the user because it is not facing him.

Selon une variante, lesdits orifices peuvent être surmontés d'un nombre correspondant d'ouvertures permettant l'insertion d'un outil pour fléchir la ou les lames ressort, une butée étant alors prévue en fond du logement.According to a variant, said orifices can be surmounted by a number corresponding of openings allowing the insertion of a tool to flex the blades spring, a stop being then provided at the bottom of the housing.

L'outil utilisé, par exemple un tournevis, est inséré en biais parallèlement à l'une des portions de la lame ressort, sur laquelle on exerce une pression en imprimant une rotation à la lame de l'outil autour d'un axe identifié à la zone de contact linéaire entre l'extrémité de l'outil et la butée.The tool used, for example a screwdriver, is inserted at an angle parallel to one portions of the leaf spring, on which pressure is exerted by printing a rotation with the blade of the tool around an axis identified with the linear contact zone between the end of the tool and the stop.

Selon une autre variante, ces lames ressorts sont surmontées d'un nombre correspondant de boutons poussoirs accessibles en façade de l'appareil, et permettant également de les fléchir.According to another variant, these leaf springs are surmounted by a number corresponding push buttons accessible on the front of the device, and also allowing them to flex.

Les poussoirs eux-mêmes peuvent être manipulés soit avec un outil, soit manuellement.The pushers themselves can be handled either with a tool or manually.

Pour permettre la mise en oeuvre de procédures de tests de la qualité du raccordement, la façade de l'appareil peut être dotée d'un orifice de test placé en regard de l'excroissance précitée équipant la borne et s'étendant en direction dudit orifice.To allow the implementation of quality testing procedures connection, the front of the device can be fitted with a test hole placed in look of the aforementioned outgrowth equipping the terminal and extending towards said orifice.

Cette protubérance est à cet effet orientée approximativement perpendiculairement à la portion sur laquelle est fixée la lame ressort.This protuberance is for this purpose oriented approximately perpendicular to the portion on which the leaf spring is fixed.

L'invention va à présent être décrite plus en détails, en référence aux figures annexées, pour lesquelles:

  • la figure 1 représente un double connecteur selon l'invention, en vue perspective ;
  • la figure 2 montre sous un autre angle la configuration de la figure 1, agrémentée de boutons poussoirs coopérant avec les lames ressorts ;
  • la figure 3 représente une configuration avec outil de manipulation, dont le fonctionnement est illustré par rapport au boítier d'un appareil électrique modulaire ;
  • la figure 4 représente le même dispositif de raccordement, inséré à un boítier d'appareil électrique modulaire, les orifices d'accès étant pratiqués dans un capot doté de canons de guidage, ledit capot étant figuré à distance du boítier ; et
  • la figure 5 représente la même vue que la figure 4, ledit capot étant à présent fixé au boítier.
    • The invention will now be described in more detail, with reference to the appended figures, for which:
  • FIG. 1 represents a double connector according to the invention, in perspective view;
  • Figure 2 shows from another angle the configuration of Figure 1, embellished with push buttons cooperating with the leaf springs;
  • Figure 3 shows a configuration with manipulation tool, the operation of which is illustrated with respect to the housing of a modular electrical appliance;
  • FIG. 4 represents the same connection device, inserted into a modular electrical appliance box, the access orifices being formed in a cover provided with guide guns, said cover being shown at a distance from the box; and
  • Figure 5 shows the same view as Figure 4, said cover now being attached to the housing.

    • Dans la représentation de la figure 1, la borne (1) est surmontée de deux lames ressorts (2) et (3) auxquelles sont fixées des plaques terminales (4) et (5), d'allure perpendiculaire à la borne (1).In the representation of Figure 1, the terminal (1) is surmounted by two blades springs (2) and (3) to which end plates (4) and (5) are attached, having the appearance perpendicular to the terminal (1).

    Du côté desdites plaques terminales (4) et (5), la borne (1) est divisée en deux portions (6, 7) engagées respectivement dans des orifices (8) et (9) pratiqués dans les plaques (4) et (5). Les portions d'extrémité (6) et (7) sont elles-mêmes munies de bossages (10, 11) orientés vers le bas, et permettant de plaquer les conducteurs contre la surface inférieure de la borne (1).On the side of said end plates (4) and (5), the terminal (1) is divided into two portions (6, 7) engaged respectively in holes (8) and (9) made in plates (4) and (5). The end portions (6) and (7) are themselves provided with bosses (10, 11) oriented downwards, and making it possible to press the conductors against the lower surface of the terminal (1).

    L'autre extrémité de la borne (1) est munie d'une portion (12) s'étendant dans une direction globalement perpendiculaire au plan moyen de la borne 1, dont le fonctionnement sera explicité plus en détail dans la suite. Dans la configuration représentée en figure 1, les lames ressorts (2) et (3) sont serties en partie supérieure des plaques terminales (4) et (5). A leur autre extrémité, la fixation est réalisée à l'aide d'un cylindre (13, 14) engagé dans un orifice circulaire pratiqué dans lesdites lames ressort (2) et (3). Les fenêtres (8) et (9) présentent une largeur identique à celle des lames ressorts (2) et (3), ce qui constitue l'un des avantages de l'invention. Pour offrir cette caractéristique, les plaques terminales (4) et (5) sont légèrement décalées, de sorte qu'elles se chevauchent au niveau des montants respectivement droit et gauche de leurs orifices (8) et (9). Cette configuration aboutit à proposer un orifice de connexion de la surface la plus large possible, tout en permettant l'établissement d'une double connexion dans la largeur d'un appareil électrique modulaire standard.The other end of the terminal (1) is provided with a portion (12) extending in a direction generally perpendicular to the mean plane of terminal 1, the operation will be explained in more detail below. In the configuration shown in Figure 1, the leaf springs (2) and (3) are partially crimped upper end plates (4) and (5). At their other end, the attachment is produced using a cylinder (13, 14) engaged in a circular orifice made in said spring blades (2) and (3). Windows (8) and (9) have a width identical to that of leaf springs (2) and (3), which is one of the advantages of the invention. To provide this feature, the end plates (4) and (5) are slightly offset, so that they overlap at the uprights respectively right and left of their orifices (8) and (9). This configuration results in proposing a connection port of the widest possible surface, all allowing the establishment of a double connection across the width of a device standard modular electric.

    La figure 2 reprend à l'identique la configuration de la figure 1, à laquelle sont ajoutés des boutons poussoirs (15, 16) permettant la manipulation des lames ressorts (2) et (3). Le bouton (15) présente sur sa face latérale un trou oblong (17) permettant son guidage en translation rectiligne à l'aide d'un ergot dépassant de la paroi interne du boítier (non représenté) en regard de ce trou oblong (17). La même possibilité existe sur la face latérale cadrée du bouton poussoir (16).Figure 2 is identical to the configuration of Figure 1, which are added push buttons (15, 16) allowing the manipulation of the blades springs (2) and (3). The button (15) has an oblong hole (17) on its side face allowing its guidance in rectilinear translation using a lug protruding from the inner wall of the housing (not shown) opposite this oblong hole (17). The same possibility exists on the framed side face of the push button (16).

    En référence à la figure 3, la configuration montrée permet d'opérer un fléchissement des lames ressorts à l'aide d'un outil (O) dont la lame est insérée dans le boítier (B) de l'appareil modulaire, jusqu'à arriver au contact d'une butée (18) disposée entre la façade (F) dudit boítier et la borne (1).With reference to FIG. 3, the configuration shown makes it possible to operate a deflection of the leaf springs using a tool (O) of which the leaf is inserted in the housing (B) of the modular device, until it comes into contact with a stop (18) disposed between the front (F) of said housing and the terminal (1).

    La face du boítier (B) de l'appareil électrique modulaire par laquelle se fait la connexion est dotée d'un canon de guidage (19), mieux visible dans les figures suivantes, dont les orifices d'insertion des conducteurs (20, 21) sont évidemment disposés sous la borne (1).The face of the housing (B) of the modular electrical device through which the connection has a guide bush (19), better visible in the figures following, whose conductor insertion holes (20, 21) are obviously arranged under the terminal (1).

    L'utilité de la protubérance (12) apparaít également dans cette figure 3. Elle comporte en réalité deux portions, une portion d'allure perpendiculaire à la borne (1), et une seconde portion inclinée qui se dirige vers un orifice (22) pratiqué dans la façade. Cet orifice (22) permet d'accéder aux parties sous tension avec un instrument de type testeur, lequel pourra tester l'état des connexions par contact avec la protubérance (12).The utility of the protuberance (12) also appears in this figure 3. It actually has two portions, a portion of shape perpendicular to the terminal (1), and a second inclined portion which goes towards an orifice (22) made in the facade. This orifice (22) provides access to the live parts with a tester type instrument, which can test the state of contact connections with the protuberance (12).

    En référence à la figure 4, le canon de guidage apparaít disjoint du boítier (B) de l'appareil modulaire, et comporte notamment deux orifices supérieurs référencés (23, 24) permettant le passage de la lame de l'outil (O). Celle-ci est insérée au-dessus des plaques terminales (4) et (5), et est guidée en biais entre les portions inclinées des lames ressorts (2) et (3) et un plan incliné menant à la butée (18). La sollicitation des lames de ressorts se fait par pivotement de la lame de l'outil (O) autour d'un axe théorique situé dans la zone de contact entre l'extrémité de la lame et le fond arrondi de ladite butée (18).Referring to Figure 4, the guide barrel appears disjoint from the housing (B) of the modular device, and in particular comprises two upper orifices referenced (23, 24) allowing the passage of the tool blade (O). This is inserted above end plates (4) and (5), and is biased between the portions inclined leaf springs (2) and (3) and an inclined plane leading to the stop (18). The biasing of the spring blades is done by pivoting the tool blade (O) around a theoretical axis located in the contact zone between the end of the blade and the rounded bottom of said stopper (18).

    La figure 5 est identique à la précédente, avec le canon de guidage à présent fixé sur le boítier (B) de l'appareillage modulaire. Le connecteur de l'invention est alors complètement masqué, l'utilisateur n'ayant accès qu'aux orifices (20, 21) d'insertion des conducteurs, aux orifices (23, 24) d'insertion d'une lame d'outil aux fins de commander l'ouverture des connecteurs, et enfin à l'orifice (22) permettant de tester la qualité des connexions.Figure 5 is identical to the previous one, with the guide barrel now fixed on the housing (B) of the modular apparatus. The connector of the invention is then completely hidden, the user having access only to the orifices (20, 21) inserting the conductors, at the holes (23, 24) inserting a tool blade at the to control the opening of the connectors, and finally to the hole (22) allowing to test the quality of the connections.

    La description ci-dessus ne constitue bien entendu qu'un exemple non limitatif de l'invention, qui englobe au contraire toutes les variantes de formes et de configurations qui sont à la portée de l'homme de l'art.The above description is of course only a non-limiting example of the invention, which on the contrary encompasses all variants of shapes and configurations which are within the reach of those skilled in the art.
