Selon cette réalisation illustrée, le disjoncteur est du type phase/neutre, présentant une largeur de sensiblement 18mm, c'est-à-dire comportant une borne de sortie de phase 1 et une borne de sortie de neutre 2. Le raccordement électrique du dispositif de raccordement A selon l'invention à l'appareil M est du type sans vis à un seul point de connexion, c'est-à-dire qu'il est réalisé par insertion d'une fiche ou dent 3,4 appartenant au dispositif de raccordement A dans la borne correspondante de l'appareil. Le raccordement électrique du dispositif de raccordement A aux appareils de départ (non représentés) s'effectue au moyen de deux câbles a,b reliés électriquement par l'une de leurs extrémités au dispositif selon l'invention A et par leur extrémité opposée aux appareils de départ.
Ainsi, le dispositif de raccordement selon l'invention propose deux points de connexion i,j pour chaque borne aval du disjoncteur ne présentant qu'un seul point de connexion k.
L'invention permet donc un double raccordement au moyen de deux câbles flexibles, rigides ou flexibles avec embouts, présentant une section maximum de 4 mm2 à l'aval d'un disjoncteur à raccordement du type sans vis, pour chaque borne respectivement de phase et de neutre présentant une section maximale de 10mm2.On the figures 1 to 4 , we see a connection device A according to a first embodiment of the invention, this device comprising a connector N intended to electrically connect the downstream terminals 1,2 of a modular device M such as a modular circuit breaker intended to be mounted on a rail mounting, at the input terminals of the starting devices (not shown).
According to this illustrated embodiment, the circuit breaker is of the phase / neutral type, having a width of approximately 18mm, that is to say comprising a phase output terminal 1 and a neutral output terminal 2. The electrical connection of the device of connection A according to the invention to the device M is of the screwless type with a single connection point, that is to say that it is produced by insertion of a plug or tooth 3,4 belonging to the device connection A in the corresponding terminal of the device. The electrical connection of the connection device A to the starting devices (not shown) is effected by means of two cables a, b electrically connected by one of their ends to the device according to invention A and by their end opposite to the devices of departure.
Thus, the connection device according to the invention provides two connection points i, j for each downstream terminal of the circuit breaker having only one connection point k.
The invention therefore allows a double connection by means of two flexible, rigid or flexible cables with ferrules, having a maximum section of 4 mm 2 downstream of a connection circuit breaker of the screwless type, for each terminal respectively of phase and neutral with a maximum section of 10mm 2 .

Tel qu'illustré sur les figures 5 et 6, à cet effet, le dispositif de raccordement A selon l'invention comporte deux dents en cuivre 3,4 aptes à être connectées respectivement dans les bornes élastiques aval 1,2 du type sans vis de l'appareil modulaire M, figures 3 et 4.
Chaque dent 3,4 est soudée à une plage 5 recevant une pièce élastique 6 comportant deux lames ressort 7,8, ces lames ressort étant aptes à coopérer avec la plage 5 de manière à permettre soit la retenue de deux parties d'extrémité respectivement de deux conducteurs a,b entre la plage 5 et respectivement les lames 7,8, afin d'établir le contact électrique entre les conducteurs a,b et la plage 5, soit la libération de la partie d'extrémité de ces conducteurs a,b par rapport à cette plage 5 par l'activation d'un moyen d'actionnement T apte à appuyer sur les lames ressorts 7,8 de manière à permettre la libération des conducteurs a,b.
Ainsi, tel qu'illustré sur les figures 5 et 6, l'on voit que cette plage 5 comporte deux découpes 9,10 formant deux orifices 11,12 permettant le passage respectivement de l'extrémité libre de deux conducteurs a,b, ces deux orifices étant obturés par la présence d'une portion de lames ressorts 7,8 en position inactivée du moyen d'actionnement T, et étant aptes à être libérés lors de l'activation du moyen d'actionnement de manière à permettre l'introduction de ces extrémités libres des conducteurs, ces extrémités libres étant ensuite retenues dans les orifices 11,12, entre la plage et la lame ressort, lorsque le moyen d'actionnement T n'est plus activé.
Tel qu'illustré sur la figure 6, l'on voit que ce dispositif de raccordement A est logé dans un boîtier B, ce boîtier comportant une partie centrale c, cette partie centrale c comportant deux orifices 13,14 de raccordement d'un câble a,b, et de part et d'autre de cette partie centrale c, un évidement 15,16, chaque évidement étant destiné à recevoir un ensemble E tel qu'illustré sur la figure 5, comportant une dent 3,4, une plage 5, une pièce 6 supportant deux lames ressort 7,8 et un moyen d'actionnement T sous la forme d'un poussoir.
Ce dispositif de raccordement comporte également deux flancs d,e aptes à être montés de part et d'autre de cette partie centrale c, et fixés sur cette partie centrale c, après montage des deux ensembles comportant chacun une dent 3,4, une plage 5, deux lames ressorts 7,8 et un poussoir T, respectivement dans les deux évidements 15,16 prévus dans cette partie centrale c.
Ce dispositif selon l'invention permet de connecter l'un des câbles d'alimentation de l'auxiliaire de mesure sur l'une des bornes de sortie du dispositif de raccordement 13,14, en conservant un point de connexion libre pour le câble de la charge.
Sur la figure 7, on voit un dispositif de raccordement C selon une seconde réalisation particulière, proposant trois points de connexion l,m,n pour chaque borne aval 1,2 du disjoncteur M ne présentant qu'un seul point de connexion k.
De même que pour la réalisation précédente, le raccordement du dispositif de raccordement C à la borne aval 1, 2 du disjoncteur M s'effectue au moyen d'une dent 17 apte à être introduite dans une borne élastique aval 1,2 de l'appareil M, tel qu'illustré sur la figure 8 illustrant deux dispositifs C,D selon cette seconde réalisation de l'invention, ces dispositifs étant sur le point d'être raccordés électriquement au disjoncteur M.
Tel qu'illustré sur la figure 9, ces deux dispositifs C, D présentent chacun trois points de connexion l,m,n et o,p,q aptes à recevoir chacun un câble de raccordement à un appareil de départ, ces câbles r,s,t étant illustrés sur la figure 10. L'invention permet donc un triple raccordement au moyen de trois câbles rigides ou flexibles avec embouts présentant une section maximum de 4mm2 à l'aval d'un disjoncteur à raccordement du type sans vis, pour chaque borne respectivement de phase et de neutre présentant une section maximale de 10mm2.
Tel qu'illustré sur la figure 11, ce dispositif de raccordement selon cette seconde réalisation comporte une dent 17 de préférence réalisée en cuivre, cette dent 17 étant solidaire d'une plage de raccordement 18 comportant trois branches 19,20,21 s'étendant sensiblement parallèlement à la direction longitudinale de la dent, ces trois branches étant destinées à coopérer avec une lame ressort 22 pliée et comportant trois découpes partielles 23,24,25 formant respectivement trois ouvertures 26,27,28 aptes à être obturées par une portion de lame de forme sensiblement rectangulaire 29,30,31 reliée par l'un de ses bords à l'un des bords de l'ouverture en formant pour cette portion de lame, une charnière. Cette dent solidaire de la plage ainsi que le lame ressort sont destinées à être introduites à l'intérieur d'une enveloppe constituée par deux flans 32,33, cette enveloppe permettant à la fois le logement et la sortie de la dent à l'extérieur de ladite enveloppe. Cette enveloppe constituée par les deux flans réunis, présente sur l'un de ses côtés, trois orifices 34,35,36 destinés à permettre l'introduction respectivement des parties d'extrémité de trois câbles, ces trois parties d'extrémité étant aptes à être retenues élastiquement entre la lame ressort 22 et les branches 19,20,21 de la lame 22, en position raccordée des câbles au dispositif de raccordement.
Selon la réalisation illustrée sur les figures 7 à 11, les dents 17 des dispositifs de raccordement s'étendent suivant une direction parallèle à la direction d'introduction des câbles r,s,t dans les orifices, l'introduction et l'extension s'effectuant dans le même sens.
Selon la réalisation dite troisième illustrée sur les figures 12 à 17, l'introduction et l'extension s'effectuent suivant des sens opposés l'un par rapport à l'autre.
Les figures 15 et 16 illustrent une première réalisation du dispositif de raccordement C selon cette troisième réalisation, dans laquelle le dispositif comporte une dent 37 solidaire d'une plage 38 formée d'un ensemble de trois éléments de raccordement 39,40,41 formant des branches, ces trois éléments étant destinés à coopérer avec une lame élastique 42 comportant trois découpes 43,44,45 formant respectivement trois lamelles élastiques 46,47,48 articulées par rapport à la lame élastique 42.
La figure 17 illustre une autre réalisation de cette troisième réalisation du dispositif de raccordement C, dans laquelle la dent 49 est solidaire et reliée électriquement à deux éléments formant des branches 50,51 aptes à coopérer avec une lame élastique 52 s'étendant sur toute la largeur du dispositif de raccordement et comportant une première partie 53 comportant deux découpes 54,55 et deux lames élastiques 56,57 correspondantes aptes à coopérer avec les deux branches précitées 50,51 et une seconde partie 58 comportant trois découpes 59,60,61 associées à trois lamelles élastiques 62,63,64 aptes à coopérer avec trois parties d'extrémités appartenant respectivement à trois câbles lors du raccordement de ces câbles. L'invention permet donc un triple raccordement au moyen de trois câbles rigides ou flexibles avec embouts présentant une section maximum de 4mm2 à l'aval d'un disjoncteur à raccordement du type sans vis, pour chaque borne respectivement de phase et de neutre présentant une section maximale de 10mm2.
On notera que cette lame fonctionne par rapport aux dents et aux éléments de raccordement de la plage de la manière suivante : Une plage de cuivre 65 en contact avec les branches 50,51 sous l'effet des ressorts 56,57 conduit le courant vers les trois découpes 59,60,61, aptes à recevoir les extrémités des trois câbles (non représentés) sous l'effet charnière des lames ressorts 62,63,64.As illustrated on Figures 5 and 6 , for this purpose, the connection device A according to the invention comprises two copper teeth 3,4 able to be connected respectively in the elastic downstream terminals 1,2 of the screwless type of the modular device M, figures 3 and 4 .
Each tooth 3,4 is welded to a pad 5 receiving an elastic piece 6 comprising two spring blades 7,8, these spring blades being able to cooperate with the pad 5 so as to allow either the retention of two end portions respectively of two conductors a, b between track 5 and the blades 7,8 respectively, in order to establish the electrical contact between conductors a, b and track 5, that is to say the release of the end part of these conductors a, b with respect to this area 5 by the activation of an actuating means T able to press on the leaf springs 7,8 so as to allow the release of the conductors a, b.
So, as illustrated on Figures 5 and 6 , we see that this area 5 has two cutouts 9,10 forming two holes 11,12 allowing the passage respectively of the free end of two conductors a, b, these two holes being closed by the presence of a portion of leaf springs 7,8 in the inactivated position of the actuating means T, and being able to be released when the actuating means are activated so as to allow the introduction of these free ends of the conductors, these free ends then being retained in the holes 11,12, between the range and the leaf spring, when the actuating means T is no longer activated.
As shown in the figure 6 , it can be seen that this connection device A is housed in a housing B, this housing comprising a central part c, this central part c comprising two orifices 13, 14 for connecting a cable a, b, and on the one hand and on the other side of this central part c, a recess 15, 16, each recess being intended to receive an assembly E as illustrated on the figure 5 , comprising a tooth 3,4, a track 5, a part 6 supporting two spring blades 7,8 and an actuating means T in the form of a pusher.
This connection device also comprises two sides d, e able to be mounted on either side of this central part c, and fixed on this central part c, after mounting of the two assemblies each comprising a tooth 3,4, a range 5, two leaf springs 7,8 and a pusher T, respectively in the two recesses 15,16 provided in this central part c.
This device according to the invention makes it possible to connect one of the supply cables of the measuring aid to one of the output terminals of the connection device 13, 14, while retaining a free connection point for the connection cable. load.
On the figure 7 , we see a connection device C according to a second particular embodiment, offering three connection points l, m, n for each downstream terminal 1,2 of the circuit breaker M having only one connection point k.
As for the previous embodiment, the connection of the connection device C to the downstream terminal 1, 2 of the circuit breaker M is effected by means of a tooth 17 capable of being introduced into a resilient downstream terminal 1.2 of the device M, as illustrated on the figure 8 illustrating two devices C, D according to this second embodiment of the invention, these devices being about to be electrically connected to the circuit breaker M.
As shown in the figure 9 , these two devices C, D each have three connection points l, m, n and o, p, q able to each receive a cable for connection to a starting device, these cables r, s, t being illustrated on the figure 10 . The invention therefore allows a triple connection by means of three rigid or flexible cables with ferrules having a maximum section of 4mm 2 downstream of a circuit breaker with connection of the screwless type, for each terminal of phase and neutral respectively having a maximum section of 10mm 2 .
As shown in the figure 11 , this connection device according to this second embodiment comprises a tooth 17 preferably made of copper, this tooth 17 being integral with a connection pad 18 comprising three branches 19,20,21 extending substantially parallel to the longitudinal direction of the tooth, these three branches being intended to cooperate with a spring leaf 22 folded and comprising three partial cutouts 23,24,25 respectively forming three openings 26,27,28 able to be closed by a blade portion of substantially rectangular shape 29,30 , 31 connected by one of its edges to one of the edges of the opening forming a hinge for this portion of the blade. This tooth secured to the beach as well as the spring blade are intended to be introduced inside an envelope constituted by two blanks 32, 33, this envelope allowing both the housing and the exit of the tooth outside. of said envelope. This envelope constituted by the two joined blanks, has on one of its sides, three orifices 34, 35, 36 intended to allow the introduction respectively of the end parts of three cables, these three end parts being able to be retained elastically between the leaf spring 22 and the branches 19, 20, 21 of the leaf 22, in the position connected by the cables to the connection device.
According to the embodiment illustrated on the figures 7 to 11 , the teeth 17 of the connection devices extend in a direction parallel to the direction of introduction of the cables r, s, t into the orifices, the introduction and extension taking place in the same direction.
According to the so-called third embodiment illustrated on the Figures 12 to 17 , the introduction and extension are carried out in opposite directions to each other.
The figures 15 and 16 illustrate a first embodiment of the connection device C according to this third embodiment, in which the device comprises a tooth 37 integral with a pad 38 formed by a set of three connection elements 39, 40, 41 forming branches, these three elements being intended to cooperate with an elastic blade 42 comprising three cutouts 43,44,45 respectively forming three elastic strips 46,47,48 articulated with respect to the elastic blade 42.
The figure 17 illustrates another embodiment of this third embodiment of the connection device C, in which the tooth 49 is integral and electrically connected to two elements forming branches 50, 51 capable of cooperating with an elastic blade 52 extending over the entire width of the device of connection and comprising a first part 53 comprising two cutouts 54,55 and two corresponding elastic blades 56,57 capable of cooperating with the two aforementioned branches 50,51 and a second part 58 comprising three cutouts 59,60,61 associated with three strips elastic 62,63,64 able to cooperate with three end parts belonging respectively to three cables when these cables are connected. The invention therefore allows a triple connection by means of three rigid or flexible cables with ferrules having a maximum section of 4mm 2 downstream of a circuit breaker with connection of the screwless type, for each terminal of phase and neutral respectively having a maximum section of 10mm 2 .
It will be noted that this blade operates with respect to the teeth and to the elements for connecting the pad as follows: A copper pad 65 in contact with the branches 50, 51 under the effect of the springs 56, 57 conducts the current to the three cutouts 59,60,61, capable of receiving the ends of the three cables (not shown) under the hinge effect of the leaf springs 62,63,64.

On notera que la solidarisation des dents aux plages pourra être réalisée par tout moyen approprié, par exemple par soudure.
On notera également que les lames ressort pourront être indépendantes les unes par rapport aux autres, ou bien faire partie d'une seule et même pièce.It will be noted that the attachment of the teeth to the pads can be carried out by any suitable means, for example by welding.
It will also be noted that the spring blades may be independent from one another, or else be part of a single piece.

On a donc réalisé grâce à l'invention un dispositif de raccordement de conception simple, pour les bornes avals d'un appareil électrique, permettant d'augmenter et d'adapter si nécessaire le nombre de points et la capacité de connexion de chaque borne.
Par exemple, l'invention permet de proposer un double raccordement présentant chacun une capacité de 4 mm2 à l'aval d'un appareil ne présentant par phase qu'une sortie présentant une capacité maximum de 10 mm2.
Ainsi, le connecteur permet, à partir d'une borne aval d'un appareil, de dupliquer le nombre de points de connexion permettant, selon les types, de recevoir chacun un câble d'une section pouvant aller jusqu'à 4 mm2 de type rigide ou flexible avec ou sans embouts.Thanks to the invention, a connection device of simple design has therefore been produced for the downstream terminals of an electrical appliance, making it possible to increase and adapt if necessary the number of points and the connection capacity of each terminal.
For example, the invention makes it possible to propose a double connection each having a capacity of 4 mm 2 downstream of a device having only one output per phase having a maximum capacity of 10 mm 2 .
Thus, the connector makes it possible, from a downstream terminal of a device, to duplicate the number of connection points making it possible, depending on the types, to each receive a cable with a cross section of up to 4 mm 2 of rigid or flexible type with or without end caps.

Bien entendu, l'invention n'est pas limitée aux modes de réalisation décrits et illustrés qui n'ont été donnés qu'à titre d'exemple.Of course, the invention is not limited to the embodiments described and illustrated which have been given only by way of example.

Au contraire, l'invention comprend tous les équivalents techniques des moyens décrits ainsi que leurs combinaisons si celles-ci sont réalisées suivant son esprit.On the contrary, the invention includes all the technical equivalents of the means described, as well as their combinations if these are carried out according to the spirit.
