Description

La présente invention concerne d'une manière générale les bornes de connexion du type de celles équipant les appareils électriques pour leur raccordement aux conducteurs électriques du câble électrique propre à leur alimentation.The present invention relates generally to the terminals of connection of the type of those fitted to electrical appliances for their connection to the electrical conductors of their own electrical cable food.

Elle vise plus particulièrement celles de ces bornes de connexion qui sont communément dites à serrage automatique, c'est-à-dire celles dont le raccordement à un conducteur électrique se fait par simple enfichage de l'extrémité, préalablement dénudée, de celui-ci, sans intervention d'un quelconque outil.It relates more particularly to those of these connection terminals which are commonly called automatic clamping, that is to say those whose connection to an electrical conductor is by simply plugging in the previously stripped end of it, without the intervention of a any tool.

Plus particulièrement, encore, la présente invention vise celles de ces bornes de connexion à serrage automatique qui comportent, d'une part, un corps creux, en matière conductrice, qui, pour l'enfichage d'un conducteur électrique, ouvre sur l'extérieur par au moins une entrée d'engagement, en présentant, de part et d'autre de celle-ci, deux parois opposées, l'une inférieure, l'autre supérieure, et, d'autre part, une lame de ressort, qui présente au moins deux branches reliées en continu l'une à l'autre par un coude arrondi, à savoir, une branche de fixation, qui s'étend à l'extérieur du corps creux, au contact de la paroi inférieure de celui-ci, en étant dûment assujettie à cette paroi inférieure, et une branche de connexion, qui intervient librement, de manière élastiquement déformable, dans le corps creux, en s'étendant globalement en biais par rapport à l'entrée d'engagement de ce corps creux, en direction de sa paroi supérieure, le coude intermédiaire entre ces deux branches contournant la tranche avant de la paroi inférieure de ce corps creux.More particularly, still, the present invention relates to those of these self-tightening connection terminals which comprise, on the one hand, a hollow body, of conductive material, which for plugging in a conductor electric, opens to the outside via at least one engagement input, having, on either side thereof, two opposite walls, one lower, the other upper, and, on the other hand, a leaf spring, which has at least two branches connected continuously to each other by a rounded bend, namely, a fixing branch, which extends outside the hollow body, at contact of the bottom wall thereof, being duly subject to this lower wall, and a connecting branch, which intervenes freely, of elastically deformable, in the hollow body, extending generally at an angle to the engagement entry of this hollow body, in direction of its upper wall, the intermediate elbow between these two branches bypassing the front edge of the lower wall of this hollow body.

Dans les bornes de connexion de ce type, la lame de ressort est solidaire de la paroi inférieure du corps creux par sa branche de fixation, et, par sa branche de connexion, elle assure le serrage du conducteur électrique contre la paroi supérieure de ce corps creux.In connection terminals of this type, the leaf spring is integral of the lower wall of the hollow body by its fixing branch, and, by its connection branch, it clamps the electrical conductor against the upper wall of this hollow body.

Une borne de connexion de ce type se trouve notamment décrite dans le brevet français qui, déposé le 4 avril 1980, sous le No 80 07675, a été publié sous le No 2 480 037. A connection terminal of this type is notably described in the French patent which, filed on April 4, 1980, under No. 80 07675, was published under No 2 480 037.

Dans ce brevet français, le coude intermédiaire entre les deux branches de la lame de ressort s'étend à distance de la tranche avant de la paroi concernée du corps creux, en formant, en pratique, en avant de cette tranche avant, une boucle qui s'étend sur plus de 180°.In this French patent, the intermediate elbow between the two branches of the leaf spring extends away from the front edge of the wall concerned with the hollow body, forming, in practice, in front of this section front, a loop that extends over 180 °.

En pratique, également, dans ce brevet français, la lame de ressort porte, par un autre coude, sur la face intérieure de la paroi concernée du corps creux, et, sur la face extérieure de cette paroi, elle s'étend à plat contre celle-ci, sans aucun contact avec sa tranche avant.In practice, also, in this French patent, the leaf spring door, by another bend, on the inside face of the concerned wall of the body hollow, and, on the outer face of this wall, it lies flat against this one, without any contact with its front edge.

Cette disposition, qui, dans certaines applications, au moins, donne satisfaction, notamment parce qu'elle permet un appui d'arc-boutement de la branche de connexion de la lame de ressort sur la surface intérieure de la paroi concernée du corps creux et parce qu'elle conduit à une grande élasticité pour cette branche de connexion, peut, dans d'autres applications, être moins satisfaisante, parce que l'axe de rotation suivant lequel cette branche de connexion fléchit lors de l'engagement d'un conducteur électrique est indéterminé et qu'il en résulte que, cette branche de connexion prenant alors une position plus ou moins aléatoire, la tenue mécanique assurée, c'est-à-dire la résistance offerte par le conducteur électrique lorsqu'une traction est intempestivement exercée sur lui, est elle-même plus ou moins incertaine.This provision, which, in some applications, at least, gives satisfaction, in particular because it allows a bracing support of the connection branch of the leaf spring on the inner surface of the wall concerned with the hollow body and because it leads to great elasticity for this connection branch, may, in other applications, be less satisfactory, because the axis of rotation along which this branch of connection flexes when engaging an electrical conductor is indeterminate and it follows that this branch of connection then taking a more or less random position, the mechanical strength ensured, that is to say resistance offered by the electrical conductor when traction is inadvertently exerted on him, is itself more or less uncertain.

Dans le modèle d'utilité allemand No 82 32 135.3, qui, par ailleurs, ne concerne pas exactement une borne de connexion de même type dans la mesure, au moins, où, d'une part, le coude de la lame de ressort se situe du côté opposé à l'entrée d'engagement du corps creux, et où, d'autre part, celui-ci ne comporte qu'une paroi, le serrage du conducteur électrique se faisant sur la surface intérieure même de cette paroi, la lame de ressort est au contact d'une des tranches de cette paroi par son coude, en l'espèce sa tranche arrière.In the German utility model No 82 32 135.3, which, moreover, does not not exactly concerns a connection terminal of the same type in the measure, at least, where, on the one hand, the bend of the leaf spring is located side opposite to the entry of engagement of the hollow body, and where, on the other hand, this one has only one wall, the electrical conductor being clamped on the very inner surface of this wall, the leaf spring is in contact one of the edges of this wall by its elbow, in this case its edge back.

Plus précisément, la lame de ressort porte au repos sur la totalité de cette tranche.More specifically, the leaf spring bears at rest on the whole of this slice.

Mais, du fait même que le coude de la lame de ressort se situe ainsi du côté opposé à celui suivant lequel se fait l'engagement d'un conducteur électrique, la branche de fixation de la lame de ressort est inévitablement l'objet d'une flexion lors d'un tel engagement, par pivotement autour de la zone par laquelle elle est assujettie à la paroi du corps creux, et son coude s'écarte alors de la tranche correspondante de cette paroi.But, by the very fact that the elbow of the leaf spring is thus located side opposite to that on which a driver is engaged electric, the spring blade fixing branch is inevitably subject to bending during such engagement, by pivoting around the area by which it is subject to the wall of the hollow body, and its elbow then deviates from the corresponding edge of this wall.

Il en résulte que, comme précédemment, l'axe de rotation de la branche de connexion de la lame de ressort est indéterminé, avec les inconvénients que cela implique.It follows that, as before, the axis of rotation of the branch of connection of the leaf spring is undetermined, with the disadvantages that that implies.

La présente invention a d'une manière générale pour objet une disposition permettant d'éviter ces inconvénients.The present invention generally relates to a provision to avoid these drawbacks.

De manière plus précise, elle a pour objet une borne de connexion à serrage automatique du genre comportant, d'une part, un corps creux, en matière conductrice, qui ouvre sur l'extérieur par au moins une entrée d'engagement, en présentant, de part et d'autre de celle-ci, deux parois opposées, l'une inférieure, l'autre supérieure, et, d'autre part, une lame de ressort, qui présente au moins deux branches reliées en continu l'une à l'autre par un coude arrondi, à savoir, une branche de fixation, qui s'étend à l'extérieur du corps creux, au contact de la paroi inférieure de celui-ci, en étant dûment assujettie à cette paroi inférieure, et une branche de connexion, qui intervient librement, de manière élastiquement déformable, dans le corps creux, en s'étendant globalement en biais par rapport à l'entrée d'engagement de ce corps creux, en direction de la paroi supérieure de celui-ci, le coude intermédiaire entre ces deux branches contournant la tranche avant de la paroi inférieure de ce corps creux, cette borne de connexion étant d'une manière générale caractérisée en ce que la lame de ressort, qui est au contact de la tranche avant de la paroi inférieure du corps creux par son coude, ne porte contre cette tranche avant que par l'arête inférieure de celle-ci.More specifically, it relates to a connection terminal to automatic clamping of the kind comprising, on the one hand, a hollow body, in conductive material, which opens to the outside via at least one inlet of engagement, by presenting, on either side of it, two walls opposite, one lower, the other upper, and, on the other hand, a blade of spring, which has at least two branches continuously connected to each other by a rounded bend, namely, a fixing branch, which extends to the exterior of the hollow body, in contact with the bottom wall thereof, being duly secured to this lower wall, and a connecting branch, which intervenes freely, elastically deformable, in the body hollow, extending generally at an angle to the engagement input of this hollow body, in the direction of the upper wall thereof, the elbow intermediate between these two branches bypassing the front edge of the wall bottom of this hollow body, this connection terminal being in a way general characterized in that the leaf spring, which is in contact with the front edge of the lower wall of the hollow body by its elbow, does not bear against this edge before that by the lower edge thereof.

Grâce à cette disposition, l'axe de rotation suivant lequel la branche de connexion de la lame de ressort fléchit lors de l'engagement d'un conducteur électrique est avantageusement bien déterminé, puisqu'il se trouve matérialisé par l'arête inférieure de la paroi inférieure du corps creux, au bénéfice des conditions de travail de cette branche de connexion, et, notamment, au bénéfice de la tenue mécanique qu'elle assure à l'égard du conducteur électrique.Thanks to this arrangement, the axis of rotation along which the branch of leaf spring connection flexes when engaging a conductor electric is advantageously well determined, since it is materialized by the lower edge of the lower wall of the hollow body, for the benefit of working conditions of this branch of connection, and, in particular, at benefit of the mechanical resistance it provides towards the driver electric.

    • Tel qu'illustré sur ces figures, et de manière connue en soi, la borne de connexion 10 suivant l'invention comporte, globalement, d'une part, un corps creux 11, en matière conductrice, qui ouvre sur l'extérieur par au moins une entrée d'engagement 12, en présentant, de part et d'autre de celle-ci, deux parois 13, 14 opposées, l'une inférieure, formant plancher, l'autre supérieure, formant toit, et, d'autre part, une lame de ressort 15, qui présente au moins deux branches 16, 18 reliées en continu l'une à l'autre par un coude 19 arrondi, à savoir, une branche de fixation 16, qui s'étend à l'extérieur du corps creux 11, au contact de la paroi inférieure 13 de celui-ci, en étant dûment assujettie à cette paroi inférieure 13 suivant des dispositions décrites plus en détail ultérieurement, et une branche de connexion 18, qui intervient librement, de manière élastiquement déformable, dans le corps creux 11, en s'étendant globalement en biais par rapport à l'entrée d'engagement 12 de ce corps creux 11, en direction de la paroi supérieure 14 de celui-ci, le coude 19 intermédiaire entre ces deux branches 16, 18 contournant la tranche avant 22 de la paroi inférieure 13 de ce corps creux 11.As illustrated in these figures, and in a manner known per se, the terminal of connection 10 according to the invention comprises, overall, on the one hand, a body hollow 11, of conductive material, which opens to the outside by at least one engagement entry 12, by presenting, on either side thereof, two opposite walls 13, 14, one lower, forming a floor, the other upper, forming a roof, and, on the other hand, a spring leaf 15, which has at least two branches 16, 18 continuously connected to each other by an elbow 19 rounded, namely, a fixing branch 16, which extends outside the body hollow 11, in contact with the bottom wall 13 thereof, being duly subject to this lower wall 13 according to arrangements described more in detail later, and a connecting branch 18, which intervenes freely, elastically deformable, in the hollow body 11, extending generally at an angle to the engagement input 12 of this hollow body 11, towards the upper wall 14 thereof, the intermediate bend 19 between these two branches 16, 18 bypassing the front edge 22 of the wall lower 13 of this hollow body 11.

    Suivant l'invention, et ainsi qu'il est mieux visible sur les figures 4 et 5, la lame de ressort 15, qui est au contact de la tranche avant 22 de la paroi inférieure 13 du corps creux 11 par son coude 19, ne porte contre cette tranche avant 22 que par l'arête inférieure 23 de celle-ci.According to the invention, and as it is better visible in FIGS. 4 and 5, the leaf spring 15, which is in contact with the front edge 22 of the wall lower 13 of the hollow body 11 by its elbow 19, does not bear against this front edge 22 only by the lower edge 23 thereof.

    Dans les formes de réalisation représentées, le corps creux 11 comporte, parallèlement l'une à l'autre, pour une même paroi inférieure 13, deux entrées d'engagement 12, dont la largeur est inférieure à la moitié de celle de cette paroi inférieure 13, et qui sont de ce fait séparées l'une de l'autre par une fente 24.In the embodiments shown, the hollow body 11 comprises, parallel to one another, for the same bottom wall 13, two engagement inputs 12, the width of which is less than half of that of this lower wall 13, and which are thereby separated one of the other by a slot 24.

    Soit L1 la largeur de cette fente 24.Let L1 be the width of this slot 24.

    Pour chacune des entrées d'engagement 12, le corps creux 11 comporte une paroi supérieure 14 individuelle.For each of the engagement inputs 12, the hollow body 11 has an individual upper wall 14.

    Il comporte donc, parallèlement l'une à l'autre, deux parois supérieures 14. It therefore comprises, parallel to each other, two upper walls 14.

    Dans les formes de réalisation représentées, le corps creux 11 comporte, venues d'un seul tenant de sa paroi inférieure 13, deux parois latérales 26, qui s'étendent sensiblement parallèlement l'une à l'autre, et, en pratique, sensiblement perpendiculairement à la paroi inférieure 13, et ses parois supérieures 14 forment elles-mêmes des retours, qui, dirigés vers l'intérieur, viennent chacun, respectivement, d'un seul tenant de ces parois latérales 26.In the embodiments shown, the hollow body 11 comprises, coming in one piece from its lower wall 13, two walls lateral 26, which extend substantially parallel to each other, and, in practical, substantially perpendicular to the bottom wall 13, and its upper walls 14 themselves form returns, which, directed towards the interior, each comes, respectively, in one piece from these walls side 26.

    Dans les formes de réalisation représentées, les parois supérieures 14 du corps creux 11 sont cintrées, sensiblement en arc de cercle, avec leur concavité tournée vers la paroi inférieure 13.In the embodiments shown, the upper walls 14 of the hollow body 11 are curved, substantially in an arc, with their concavity facing the bottom wall 13.

    Elles comportent chacune, le long de leur bord libre, un retour 27, qui s'étend en direction de la paroi inférieure 13, parallèlement aux parois latérales 26, et dont la hauteur est réduite par rapport à celle de ces dernières.They each have, along their free edge, a return 27, which extends towards the bottom wall 13, parallel to the side walls 26, and whose height is reduced relative to that of the latter.

    A l'arrière, les parois latérales 26 sont très largement échancrées par un décrochement 28, dont il résulte qu'elles laissent dégagée la portion arrière 29 des bords longitudinaux 30 de la paroi inférieure 13.At the rear, the side walls 26 are very largely indented by a recess 28, which results in leaving the rear portion 29 clear longitudinal edges 30 of the bottom wall 13.

    Dans les formes de réalisation représentées, cette paroi inférieure 13 du corps creux 11 se prolonge, à l'arrière, par une patte de contact 31, munie, en saillie, d'un grain de contact 32.In the embodiments shown, this bottom wall 13 of the hollow body 11 is extended, at the rear, by a contact tab 31, provided, in projection, of a contact grain 32.

    Mais, abstraction faite de cette patte de contact 31, le corps creux 11 relève, globalement, d'une surface réglée dont toutes les génératrices sont parallèles entre elles, à la manière d'un corps tubulaire.But, apart from this contact tab 31, the hollow body 11 generally falls within a regulated area of which all the generators are parallel to each other, like a tubular body.

    Il peut ainsi très simplement être réalisé par découpe, pliage et mise en forme d'un quelconque feuillard métallique.It can thus very simply be produced by cutting, folding and placing shape of any metallic strip.

    Dans les formes de réalisation représentées, la lame de ressort 15 comporte, parallèlement l'une à l'autre, pour une même branche de fixation 1 6, deux branches de connexion 18, qui correspondent chacune respectivement aux deux entrées d'engagement 12 du corps creux 11, et qui sont séparées l'une de l'autre par une fente 34.In the embodiments shown, the leaf spring 15 comprises, parallel to one another, for the same fixing branch 1 6, two connection branches 18, which each correspond respectively to the two engagement inputs 12 of the hollow body 11, and which are separated from each other by a slot 34.

    Soit L2 la largeur de cette fente 34. Let L2 be the width of this slot 34.

    Cette largeur L2 est très largement inférieure à la largeur L1 de la fente 24 séparant l'une de l'autre les deux entrées d'engagement 12 du corps creux 11.This width L2 is very much less than the width L1 of the slot 24 separating the two engagement inlets 12 from the hollow body from one another 11.

    Mais, par un fractionnement de leur extrémité libre, les deux branches de connexion 18 forment, chacune, latéralement, le long de cette fente 34, une languette 35, qui, pliée sensiblement parallèlement à la branche de fixation 16, fait saillie sur leur partie courante du même côté que cette branche de fixation 16, et par laquelle elles sont chacune respectivement aptes à porter sur le bord libre du retour 27 de la paroi supérieure 14 correspondante du corps creux 11.But, by splitting their free end, the two branches connection 18 each form laterally along this slot 34, a tongue 35, which, folded substantially parallel to the fixing branch 16, protrudes on their current part on the same side as this branch of attachment 16, and by which they are each respectively capable of carrying on the free edge of the return 27 of the corresponding upper wall 14 of the hollow body 11.

    Dans les formes de réalisation représentées, cette languette 35 est arrondie, avec sa concavité tournée vers la paroi inférieure 13 du corps creux 11.In the embodiments shown, this tongue 35 is rounded, with its concavity facing the bottom wall 13 of the hollow body 11.

    En outre, dans ces formes de réalisation, le retour 27 des parois supérieures 14 du corps creux 11 présente, en correspondance, une encoche 36, qui, de manière complémentaire, est elle-même arrondie.Furthermore, in these embodiments, the return 27 of the walls upper 14 of the hollow body 11 has, in correspondence, a notch 36, which, in addition, is itself rounded.

    Du fait des différences entre les largeurs L1, L2 des fentes 24, 34, la languette 35 de chacune des branches de connexion 18 s'étend transversalement au-delà du retour 27 de la paroi supérieure 14 correspondante du corps creux 11, et, débordant ainsi dans la fente 24 de celui-ci, elle est accessible à la faveur de cette fente 24.Due to the differences between the widths L1, L2 of the slots 24, 34, the tongue 35 of each of the connecting branches 18 extends transversely beyond the return 27 of the upper wall 14 corresponding to the hollow body 11, and thus projecting into the slot 24 of this one, it is accessible thanks to this slot 24.

    Abstraction faite de leur languette 35, les branches de connexion 18 de la lame de ressort 15 s'étendent de manière sensiblement rectiligne à compter du coude 19 qui les relie à la branche de fixation 16.Leaving aside their tongue 35, the connecting branches 18 of the leaf spring 15 extend in a substantially rectilinear manner from of the elbow 19 which connects them to the fixing branch 16.

    Il en est sensiblement de même pour cette dernière.It is much the same for the latter.

    La lame de ressort 15 ainsi constituée peut très simplement être réalisée à l'aide d'un feuillard en acier à ressort convenablement découpé, conformé et traité.The leaf spring 15 thus formed can very simply be produced using a spring steel strip suitably cut, shaped and treaty.

    Pour l'assujettissement de la lame de ressort 15 à sa paroi inférieure 13, le corps creux 11 comporte, dans les formes de réalisation représentées, au moins une patte de fixation 38, qui, solidaire de cette paroi inférieure 13, est repliée en U au contact de la branche de fixation 16 de cette lame de ressort 15.To secure the spring leaf 15 to its bottom wall 13, the hollow body 11 comprises, in the embodiments shown, at at least one fixing lug 38, which, integral with this lower wall 13, is folded in a U in contact with the fixing branch 16 of this leaf spring 15.

    Préférentiellement, et cela est le cas dans les formes de réalisation représentées, le corps creux 11 comporte deux pattes de fixation 38, qui, intervenant chacune respectivement le long des deux bords longitudinaux 30 de sa paroi inférieure 13, enserrent globalement transversalement la branche de fixation 16 de la lame de ressort 15.Preferably, and this is the case in the embodiments shown, the hollow body 11 comprises two fixing lugs 38, which, each acting respectively along the two longitudinal edges 30 from its bottom wall 13, generally enclose the branch transversely fixing plate 16 of the spring leaf 15.

    Préférentiellement, et tel que représenté, ces deux pattes de fixation 38 viennent d'un seul tenant de la paroi inférieure 13 du corps creux 11 à la faveur de la portion arrière 29 dégagée des bords longitudinaux 30 de celle-ci.Preferably, and as shown, these two fixing lugs 38 come in one piece from the bottom wall 13 of the hollow body 11 to the favor of the rear portion 29 released from the longitudinal edges 30 thereof.

    Dans les formes de réalisation plus particulièrement représentées sur les figures 1 à 9, les deux pattes de fixation 38 s'étendent sensiblement parallèlement l'une à l'autre, et il en est de même des portions 39, au moins, des bords longitudinaux 40 de la branche de fixation 16 de la lame de ressort 15 concernées par ces pattes de fixation 38.In the embodiments more particularly represented on the Figures 1 to 9, the two fixing lugs 38 extend substantially parallel to each other, and the same is true for portions 39, at least, longitudinal edges 40 of the securing branch 16 of the leaf spring 15 concerned by these fixing lugs 38.

    En variante, figures 10 à 13, les deux pattes de fixation 38 que forme le corps creux 11 s'étendent globalement en biais l'une par rapport à l'autre, en divergeant l'une par rapport à l'autre en direction opposée aux entrées d'engagement 12 de ce corps creux 11, et il en est de même des portions 39, au moins, des bords longitudinaux 40 de la branche de fixation 16 de la lame de ressort 15 concernées par ces pattes de fixation 38.As a variant, FIGS. 10 to 13, the two fixing lugs 38 formed by the hollow body 11 generally extend at an angle to each other, in diverging from one another in the opposite direction to the inputs engagement 12 of this hollow body 11, and the same is true of the portions 39, at least longitudinal edges 40 of the attachment branch 16 of the blade spring 15 concerned by these fixing lugs 38.

    Dans l'un et l'autre cas, les portions 39 en cause des bords longitudinaux 40 de la branche de fixation 16 de la lame de ressort 15 sont en retrait par rapport à la partie courante de ces bords longitudinaux 40.In either case, the portions 39 in question of the edges 40 of the securing branch 16 of the leaf spring 15 are in withdrawal with respect to the current part of these longitudinal edges 40.

    Préférentiellement, et cela est le cas dans les formes de réalisation représentées, des moyens d'indexation sont prévus entre la branche de fixation 16 de la lame de ressort 15 et le corps creux 11, pour un meilleur contrôle de position de cette lame de ressort 15 par rapport à ce corps creux 11 au montage.Preferably, and this is the case in the embodiments shown, indexing means are provided between the branch of fixing 16 of the spring leaf 15 and the hollow body 11, for better position control of this leaf spring 15 relative to this hollow body 11 during assembly.

    Dans les formes de réalisation plus particulièrement représentées sur les figures 1 à 9, ces moyens d'indexation comportent, sur la branche de fixation 16 de la lame de ressort 15, au moins un épaulement 41, qui s'étend transversalement par rapport à ses bords longitudinaux 40, et par lequel cette branche de fixation 16 porte sur la tranche latérale avant de la patte de fixation 38 correspondante du corps creux 11.In the embodiments more particularly represented on the Figures 1 to 9, these indexing means comprise, on the fixing branch 16 of the leaf spring 15, at least one shoulder 41, which extends transversely to its longitudinal edges 40, and by which this fastening arm 16 carries on the front side edge of the lug corresponding fixing 38 of the hollow body 11.

    En pratique, deux épaulements 41 sont prévus, à raison d'un par bord longitudinal 40, et, donc, à raison d'un par patte de fixation 38.In practice, two shoulders 41 are provided, one per edge. longitudinal 40, and therefore at the rate of one per fixing lug 38.

    Dans les formes de réalisation représentées sur les figures 10 à 13, les moyens d'indexation résultent très simplement du montage en queue d'aronde assuré par les pattes de fixation 38 en raison de leur obliquité l'une par rapport à l'autre.In the embodiments shown in Figures 10 to 13, the indexing means very simply result from the dovetail mounting provided by the fixing lugs 38 due to their obliquity one with respect to to the other.

    De ce point de vue, ce montage en queue d'aronde exige avantageusement moins de précision à la fabrication.From this point of view, this dovetail assembly requires advantageously less manufacturing precision.

    Préférentiellement, et cela est le cas dans les formes de réalisation représentées, entre la branche de fixation 16 de la lame de ressort 15 et le corps creux 11 sont également prévus des moyens de retenue, pour éviter que cette lame de ressort 15 puisse échapper au corps creux 11 si elle vient à être l'objet d'une traction.Preferably, and this is the case in the embodiments shown, between the securing branch 16 of the spring leaf 15 and the retaining means 11 are also provided, to prevent this leaf spring 15 can escape the hollow body 11 if it comes to be subject to traction.

    Dans la forme de réalisation plus particulièrement représentée sur les figures 1 à 6 ces moyens de retenue comportent, sur la branche de fixation 16 de la lame de ressort 15, au moins un épaulement 43, qui s'étend transversalement par rapport à ses bords longitudinaux 40, et par lequel cette branche de fixation 16 porte sur la tranche latérale arrière de la patte de fixation 38 correspondante du corps creux 11.In the embodiment more particularly represented on the Figures 1 to 6 these retaining means comprise, on the fixing branch 16 of the leaf spring 15, at least one shoulder 43, which extends transversely to its longitudinal edges 40, and by which this fastening branch 16 door on the rear side edge of the lug corresponding fixing 38 of the hollow body 11.

    En pratique, deux épaulements 43 sont prévus, à raison d'un par bord longitudinal 40.In practice, two shoulders 43 are provided, one per edge. longitudinal 40.

    Pour chacun des bords longitudinaux 40 de la branche de fixation 16, l'épaulement 41 appartenant aux moyens d'indexation et celui 43 appartenant aux moyens de retenue sont formés par les bords latéraux d'une même encoche 44 par laquelle la branche de fixation 16 de la lame de ressort 15 est en prise avec la patte de fixation 38 correspondante du corps creux 11. For each of the longitudinal edges 40 of the fixing branch 16, the shoulder 41 belonging to the indexing means and that 43 belonging the retaining means are formed by the lateral edges of the same notch 44 by which the securing branch 16 of the spring leaf 15 is in engagement with the corresponding fixing lug 38 of the hollow body 11.

    La branche de fixation 16 de la lame de ressort 15 présente donc une encoche 44 sur chacun de ses bords longitudinaux 40 dans cette forme de réalisation et la portion 39 de ceux-ci concernée par les pattes de fixation 38 du corps creux 11 en forme le fond.The attachment branch 16 of the spring leaf 15 therefore has a notch 44 on each of its longitudinal edges 40 in this form of realization and the portion 39 thereof concerned by the fixing lugs 38 the hollow body 11 forms the bottom.

    La branche de fixation 16 de la lame de ressort 15 présente, donc, latéralement, sur ses bords longitudinaux 40, dans cette forme de réalisation, deux encoches 44 par lesquelles elle est en prise avec les pattes de fixation 38 que forme en correspondance le corps creux 11.The attachment branch 16 of the spring leaf 15 therefore has laterally, on its longitudinal edges 40, in this embodiment, two notches 44 by which it engages the fixing lugs 38 that the hollow body 11 forms in correspondence.

    Dans la forme de réalisation représentée sur les figures 7 à 9, les moyens de retenue prévus suivant l'invention comportent, sur le corps creux 11, un pion 45, et, sur la branche de fixation 16 de la lame de ressort 15, un évidement 46 par lequel cette branche de fixation 16 est en prise avec le pion 45 du corps creux 11.In the embodiment shown in Figures 7 to 9, the retaining means provided according to the invention comprise, on the hollow body 11, a pin 45, and, on the attachment branch 16 of the spring leaf 15, a recess 46 by which this fixing branch 16 is engaged with the pin 45 of the hollow body 11.

    Par exemple, et tel que représenté, le pion 45 a un contour circulaire, et il en est de même, de manière complémentaire, de l'évidement 46.For example, and as shown, the pin 45 has a circular outline, and the same is true, in a complementary manner, of the recess 46.

    Corollairement, dans cette forme de réalisation, la portion 39 des bords longitudinaux 40 de la branche de fixation 16 de la lame de ressort 15 se poursuit librement jusqu'à l'extrémité libre de cette branche de fixation 16 en retrait par rapport à la portion courante de ces bords longitudinaux 40.As a corollary, in this embodiment, the portion 39 of the edges longitudinal 40 of the fixing branch 16 of the spring leaf 15 continues freely to the free end of this attachment branch 16 in withdrawal with respect to the current portion of these longitudinal edges 40.

    Dans les formes de réalisation représentées sur les figures 10 à 13, les moyens de retenue prévus suivant l'invention résultent, comme les moyens d'indexation précédents, du montage en queue d'aronde assuré par les pattes de fixation 38 du corps creux 11.In the embodiments shown in Figures 10 to 13, the retaining means provided according to the invention result, like the means previous indexing, dovetail mounting provided by the legs fixing 38 of the hollow body 11.

    Par ailleurs, dans les formes de réalisation représentées sur les figures 7 à 13, des moyens de maintien sont également prévus entre la lame de ressort 15 et le corps creux 11, pour éviter une éventuelle mise en biais de cette lame de ressort 15 par rapport à ce corps creux 11 lorsque seule une des ses branches de connexion 18 est sollicitée.Furthermore, in the embodiments shown in Figures 7 at 13, holding means are also provided between the leaf spring 15 and the hollow body 11, to avoid possible biasing of this blade spring 15 relative to this hollow body 11 when only one of its connection branches 18 is stressed.

    Par exemple, et tel que représenté, ces moyens de maintien comportent, sur le corps creux 11, un ergot 47, qui fait saillie sur la tranche avant 22 de sa paroi inférieure 13, dans la zone médiane de celle-ci, en s'étendant dans le prolongement de cette paroi inférieure 13, et, sur le coude 19 de la lame de ressort 15, à la racine de la fente 34 séparant l'une de l'autre les deux branches de connexion 18 de cette lame de ressort 15, un évidement 48 par lequel cette lame de ressort 15 est en prise avec l'ergot 47 du corps creux 11.For example, and as shown, these holding means comprise, on the hollow body 11, a lug 47, which projects on the front edge 22 of its lower wall 13, in the central region thereof, extending into the extension of this lower wall 13, and, on the elbow 19 of the blade spring 15, at the root of the slot 34 separating the two from one another connection branches 18 of this leaf spring 15, a recess 48 by which this leaf spring 15 is engaged with the lug 47 of the hollow body 11.

    Dans les formes de réalisation représentées sur les figures 7 à 10, l'ergot 47 a un contour quadrangulaire, et, par exemple, rectangulaire, et l'évidement 48 a un contour circulaire.In the embodiments shown in FIGS. 7 to 10, the lug 47 has a quadrangular contour, and, for example, rectangular, and the recess 48 has a circular outline.

    En variante, figures 11 à 13, l'ergot 47 du corps creux 11 a un contour trapézoïdal, en allant en s'amincissant en direction de son extrémité libre, ce qui favorise avantageusement un maintien de la lame de ressort 15 suivant le plan de symétrie du corps creux 11.As a variant, FIGS. 11 to 13, the lug 47 of the hollow body 11 has an outline trapezoidal, going thinner towards its free end, this which advantageously promotes retention of the leaf spring 15 according to the plane of symmetry of the hollow body 11.

    Corollairement, l'évidement 48 a un contour quadrangulaire, et, par exemple, carré, ce qui, par les épaulements qui en résultent, permet avantageusement de limiter le jeu de la lame de ressort 15 perpendiculairement à la paroi inférieure 13 du corps creux 11.As a corollary, the recess 48 has a quadrangular contour, and, by example, square, which, by the resulting shoulders, allows advantageously to limit the play of the spring leaf 15 perpendicularly to the bottom wall 13 of the hollow body 11.

    Préférentiellement, enfin, et cela est le cas, au moins, dans les formes de réalisation représentées sur les figure 10 à 13, la lame de ressort 15 est, par construction, en butée, par son coude 19, contre l'arête inférieure 23 de la tranche avant 22 de la paroi inférieure 13 du corps creux 11.Preferably, finally, and this is the case, at least, in the forms of embodiment shown in FIGS. 10 to 13, the leaf spring 15 is, by construction, in abutment, by its elbow 19, against the lower edge 23 of the front edge 22 of the bottom wall 13 of the hollow body 11.

    Au repos, et ainsi qu'il est mieux visible sur la figure 4, les branches de connexion 18 de la lame de ressort 15 portent par leur languette 35 sur le retour 27 de la paroi supérieure 14 correspondante du corps creux 11, cependant que leur extrémité libre s'étend à proximité immédiate de cette paroi supérieure 14 sans toutefois être nécessairement au contact de celle-ci.At rest, and as best seen in Figure 4, the branches of connection 18 of the leaf spring 15 carry by their tongue 35 on the return 27 of the corresponding upper wall 14 of the hollow body 11, however that their free end extends in the immediate vicinity of this wall upper 14 without however necessarily being in contact with it.

    Si, tel que schématisé par une flèche F1 sur les figures 1 et 4, un conducteur électrique 50, dont l'extrémité 51 a été au préalable dénudée, est engagé dans l'une des entrées d'engagement 12 du corps creux 11, en étant dûment guidé par celle-ci, ce conducteur électrique 50 vient porter sur l'extrémité libre de la branche de connexion 18 correspondante de la lame de ressort 15, et, si son mouvement d'engagement est poursuivi, il repousse cette branche de connexion 18, en la forçant à fléchir, tel que schématisé par la flèche F2 sur la figure 4.If, as shown by an arrow F1 in Figures 1 and 4, a electrical conductor 50, the end 51 of which has been previously stripped, is engaged in one of the engagement inputs 12 of the hollow body 11, being duly guided by it, this electrical conductor 50 comes to bear on the free end of the corresponding connection branch 18 of the blade spring 15, and, if its engagement movement is continued, it pushes back this connection branch 18, forcing it to flex, as shown schematically by arrow F2 in FIG. 4.

    Lors de ce fléchissement, la branche de connexion 18 concernée de la lame de ressort 15 pivote autour d'un axe de rotation qui, suivant l'invention, et ainsi qu'il ressort des figures 4 et 5, est avantageusement matérialisé par l'arête inférieure 23 de la tranche avant 22 de la paroi inférieure 13 du corps creux 11.During this bending, the connection branch 18 concerned of the leaf spring 15 pivots about an axis of rotation which, according to the invention, and as it appears from FIGS. 4 and 5, is advantageously materialized by the lower edge 23 of the front edge 22 of the lower wall 13 of the body hollow 11.

    L'extrémité dénudée 51 du conducteur électrique 50 s'engage alors entre l'extrémité libre de la branche de connexion 18 de la lame de ressort 15 et la paroi supérieure 14 correspondante du corps creux 11, et, du fait de l'élasticité de cette branche de connexion 18, elle se trouve automatiquement serrée entre elle et la paroi supérieure 14 du corps creux 11.The stripped end 51 of the electrical conductor 50 then engages between the free end of the connection branch 18 of the spring leaf 15 and the corresponding upper wall 14 of the hollow body 11, and, due to the elasticity of this connection branch 18, it is automatically clamped between it and the upper wall 14 of the hollow body 11.

    Pour le desserrage du conducteur électrique 50, en vue, par exemple, de son dégagement du corps creux 11, il suffit d'agir sur la languette 35 de la branche de connexion 18 concernée de la lame de ressort 15, à la faveur de la fente 24 du corps creux 11.For loosening the electrical conductor 50, with a view, for example, to its release from the hollow body 11, it suffices to act on the tongue 35 of the connection branch 18 concerned with the leaf spring 15, by means of the slot 24 of the hollow body 11.

    Tel que schématisé en traits interrompus sur la figure 1, deux conducteurs électriques 50 peuvent être engagés en parallèle dans le corps creux 11, à raison d'un par entrée d'engagement 12 de celui-ci.As shown in broken lines in Figure 1, two electrical conductors 50 can be engaged in parallel in the body hollow 11, at the rate of one per engagement entry 12 thereof.

    Bien entendu, la présente invention ne se limite pas aux formes de réalisation décrites et représentées, mais englobe toute variante d'exécution et/ou de combinaison de leurs divers éléments.Of course, the present invention is not limited to the forms of realization described and represented, but includes any variant and / or a combination of their various elements.
