Description

DOMAINE TECHNIQUE DE L'INVENTIONTECHNICAL FIELD OF THE INVENTION

L'invention est relative à un moyen de raccordement rapide de forme allongée selon un axe longitudinal et ayant deux extrémités destinées à venir se fixer respectivement avec un étrier d'une borne de raccordement d'un dispositif électrique de coupure. Ledit étrier étant constitué d'un volume de serrage délimité par deux surfaces de contact électrique mobiles l'une par rapport à l'autre au moyen d'une vis de serrage.The invention relates to a quick coupling means of elongate shape along a longitudinal axis and having two ends intended to be fixed respectively with a stirrup of a connection terminal of an electrical cut-off device. Said stirrup being constituted by a clamping volume delimited by two electrical contact surfaces movable relative to each other by means of a clamping screw.

L'invention est relative à un procédé de raccordement de deux dispositifs de coupure raccordés par au moins un moyen de raccordement.The invention relates to a method of connecting two cut-off devices connected by at least one connecting means.

ETAT DE LA TECHNIQUE ANTERIEURESTATE OF THE PRIOR ART

Le raccordement électrique de deux produits tels que des dispositifs électriques de coupure s'effectue habituellement via des câbles de liaison fixés aux dispositifs par des vis, notamment des vis hélicoïdales.The electrical connection of two products such as electrical cut-off devices is usually done via connecting cables fixed to the devices by screws, including helical screws.

A titre d'exemple, lorsque les dispositifs électriques sont des appareils tripolaires, ils sont alors reliés par trois câbles fixés par six vis. Ainsi, ce mode de liaison nécessite un temps de mise en oeuvre important (temps de serrage des six vis). En outre, ce mode de liaison est souvent associé à des risques de desserrage liés au fluage de câbles de raccordement.For example, when the electrical devices are three-pole devices, they are then connected by three cables fixed by six screws. Thus, this connection mode requires a significant implementation time (tightening time of the six screws). In addition, this connection mode is often associated with loosening risks related to the creep of connection cables.

Un autre mode de liaison connu entre deux produits utilise des connections élastiques à ressort. Ce mode nécessite la fabrication de produits spécifiques équipés de cette fonction et l'emploi d'une pièce de liaison intermédiaire (plug). L'utilisation de câble de liaison est alors impossible.
Un autre mode de laison connu entre deux dispositif électriques est décrit dans le document EP2093787A .Another known connection mode between two products uses elastic spring connections. This mode requires the manufacture of specific products equipped with this function and the use of an intermediate connecting piece (plug). The use of connecting cable is then impossible.
Another known method of connection between two electrical devices is described in the document EP2093787A .

DESCRIPTION DETAILLEE D'UN MODE DE REALISATIONDETAILED DESCRIPTION OF AN EMBODIMENT

Tel que représenté sur la figure 1, les moyens de raccordement 10 rapide sont de forme allongée selon un axe longitudinal X. Lesdits moyens comportent deux extrémités 1 destinées à venir se fixer respectivement avec un étrier 105 d'une borne de raccordement 110 d'un dispositif électrique de coupure 100.As shown on the figure 1 , the quick coupling means 10 are of elongate shape along a longitudinal axis X. Said means comprise two ends 1 intended to be fixed respectively with a stirrup 105 of a connection terminal 110 of an electrical cut-off device 100.

Les bornes de raccordement 110 des dispositifs de coupure 100 destinés à être raccordées par les moyens de raccordement 10 selon l'invention comportent respectivement un étrier 105 constitué d'un volume de serrage délimité par deux surfaces de contact électrique 106, 107 mobiles l'une par rapport à l'autre. Une vis de serrage 101 commande en translation une des surfaces de contact.The connection terminals 110 of the cut-off devices 100 intended to be connected by the connection means 10 according to the invention respectively comprise a stirrup 105 consisting of a clamping volume delimited by two electrical contact surfaces 106, 107 movable one compared to each other. A clamping screw 101 controls in translation one of the contact surfaces.

Selon un mode de développement de l'invention, chaque extrémité 1 du moyen de raccordement 10 rapide est agencée pour adopter une première position d'emboitement et une seconde position de verrouillage desdits moyens avec la borne de raccordement 110.According to a development mode of the invention, each end 1 of the quick coupling means is arranged to adopt a first interlocking position and a second locking position of said means with the connection terminal 110.

La première position est obtenue par un emboitement d'une extrémité 1 du moyen de raccordement 10 sur la vis de serrage 101 de l'étrier 105 de la borne de raccordement 110.The first position is obtained by a fitting of one end 1 of the connecting means 10 on the clamping screw 101 of the stirrup 105 of the connection terminal 110.

La seconde position est obtenue à partir de la première position d'emboitement. La seconde position de verrouillage est obtenue après une rotation du moyen de raccordement autour de l'axe longitudinal X.The second position is obtained from the first nesting position. The second locking position is obtained after a rotation of the connection means around the longitudinal axis X.

Le passage de la première position à la seconde position est réalisé par une rotation d'un angle de rotation α du moyen de raccordement 10 autour de leur axe longitudinal X.The passage from the first position to the second position is achieved by rotating an angle of rotation α of the connecting means 10 about their longitudinal axis X.

Selon une mode préférentiel de réalisation, chaque extrémité 1 comporte des surfaces d'appui SA agencées pour être en contact avec les surfaces de contact 106, 107 de l'étrier 105 dans la seconde position de verrouillage. La mise en contact des surface d'appui SA avec les surfaces de contact de l'étrier 105 permet d'assurer un contact électrique entre les moyens de raccordement 10 et la borne de raccordement 110.According to a preferred embodiment, each end 1 comprises bearing surfaces SA arranged to be in contact with the contact surfaces 106, 107 of the stirrup 105 in the second locking position. The contacting of the bearing surface SA with the contact surfaces of the stirrup 105 makes it possible to ensure electrical contact between the connection means 10 and the connection terminal 110.

Chaque extrémité 1 du moyen de raccordement 10 comporte une fente 2 s'étendant parallèlement à l'axe longitudinal X. La fente 2 sépare alors une première et une seconde branches 4, 5 de contact espacées l'une de l'autre d'une distance e.Each end 1 of the connection means 10 has a slot 2 extending parallel to the longitudinal axis X. The slot 2 then separates first and second contact legs 4, 5 spaced apart from one another. distance e.

La distance e séparant les première et seconde branches 4, 5 de contact est déterminée pour autoriser le passage et l'emboitement la vis de serrage 101 d'un étrier 105 d'une borne de raccordement 110 dans la première position d'emboitement. En outre, la distance e séparant les première et seconde branches 4, 5 de contact est déterminée pour autoriser le verrouillage et le contact électrique du moyen de raccordement rapide avec l'étrier 105 d'une borne de raccordement. Autrement dit, la distance e est au moins supérieure au diamètre de la vis de serrage 101 de l'étrier.The distance e separating the first and second contact legs 4, 5 is determined to allow the passage and the engagement of the clamping screw 101 of a stirrup 105 of a connection terminal 110 in the first interlocking position. In addition, the distance e between the first and second contact legs 4, 5 is determined to allow locking and electrical contact of the quick coupling means with the bracket 105 of a connection terminal. In other words, the distance e is at least greater than the diameter of the clamping screw 101 of the stirrup.

Comme représenté sur le figures 7A et 7B, selon un premier mode particulier de réalisation de l'invention, les fentes 2 disposées à chaque extrémité 1 du moyen de raccordement 10 se développent selon un profil hélicoïdal. La mise en place du moyen de raccordement sur les étriers, autrement dit le passage de la première position d'emboitement à la seconde position de verrouillage est obtenu en vissant les moyens de raccordement 10 sur la vis 101 dans l'étrier 105.As represented on the Figures 7A and 7B , according to a first particular mode of embodiment of the invention, the slots 2 disposed at each end 1 of the connecting means 10 develop in a helical profile. The establishment of the connecting means on the stirrups, in other words the passage from the first interlocking position to the second locking position is obtained by screwing the connection means 10 on the screw 101 in the stirrup 105.

Comme représenté sur les figures 4, 5 et 6, selon un second mode particulier de réalisation de l'invention, la première et la seconde branche 4, 5 de contact s'étendent parallèlement à l'axe longitudinal X. En outre, chaque branche comporte un dégagement 6 de matière dans sa paroi. Ce dégagement est réalisé selon une direction formant un angle de dégagement 6 par rapport à l'axe longitudinal X. A titre d'exemple, l'angle de dégagement 6 est de préférence sensiblement égal à 90°. Le dégagement 6 de la première branche 4 est fait dans une direction sensiblement opposée par rapport au dégagement de la seconde branche 5. En outre, les dégagements ont une largeur adaptée pour autoriser le passage de la vis de serrage 101 d'un étrier 105 d'une borne de raccordement 110 dans la position de verrouillage.As shown on Figures 4, 5 and 6 according to a second particular embodiment of the invention, the first and second contact legs 4, 5 extend parallel to the longitudinal axis X. In addition, each branch has a clearance 6 of material in its wall. This clearance is made in a direction forming a clearance angle 6 relative to the longitudinal axis X. For example, the clearance angle 6 is preferably substantially equal to 90 °. The clearance 6 of the first branch 4 is made in a direction substantially opposite to the clearance of the second branch 5. In addition, the recesses have a width adapted to allow the passage of the clamping screw 101 of a stirrup 105 of a connection terminal 110 in the locking position.

A titre d'exemple de réalisation, les surfaces d'appui SA destinées à venir en contact avec les surfaces de contact 106, 107 des étriers 105 sont positionnées sur des surfaces externes des branches 4, 5. Les surfaces d'appui SA ont un pourtour se développant selon une courbe correspondant la surface négative des surfaces de contact 106, 107 de l'étrier 105 des bornes de raccordement 110. A titre d'exemple de réalisation, une des surfaces d'appui SA d'une branche 4 a un pourtour se développant selon une courbe de forme convexe.As an exemplary embodiment, the bearing surfaces SA intended to come into contact with the contact surfaces 106, 107 of the stirrups 105 are positioned on external surfaces of the branches 4, 5. The bearing surfaces SA have a the periphery developing in a curve corresponding to the negative surface of the contact surfaces 106, 107 of the stirrup 105 of the connection terminals 110. As an exemplary embodiment, one of the bearing surfaces SA of a branch 4 has a perimeter developing in a convex curve.

En outre, les branches 4, 5 comportent des surfaces internes supportant des moyens de blocage des vis de serrage de l'étrier 105 dans la seconde position de verrouillage. A titre d'exemple de réalisation, les moyens de blocage sont des godrons 7 faisant saillie et se développant sensiblement de manière perpendiculaire à l'axe longitudinal X à l'intérieur les dégagements de matière des première et la seconde branches de contact.In addition, the branches 4, 5 have internal surfaces supporting locking means of the clamping screws of the bracket 105 in the second locking position. As an exemplary embodiment, the locking means are flutes 7 protruding and developing substantially perpendicular to the longitudinal axis X within the material clearances of the first and second contact legs.

Selon une variante de réalisation telle que représenté sur les figures 2 et 3, les moyens de raccordement selon l'invention comportent des moyens d'entrainement 8. Les moyens d'entrainement 8 sont destinés à collaborer avec un outil 80 pour être entrainé de la première à la seconde position. Comme représenté sur la figure 3, plusieurs moyens de raccordement selon l'invention peuvent être entrainés de manière simultanée par un seul outil 80. Selon un mode particulier de réalisation, les moyens d'entrainement 8 comportent par exemple un profil denté disposé en couronne autour d'un corps cylindrique des moyens de raccordement 10.According to an embodiment variant as represented on the Figures 2 and 3 , the connection means according to the invention comprise means 8. The driving means 8 are intended to collaborate with a tool 80 to be driven from the first to the second position. As shown on the figure 3 , several connection means according to the invention can be driven simultaneously by a single tool 80. According to a particular embodiment, the drive means 8 comprise for example a toothed profile arranged in a ring around a cylindrical body of connection means 10.

L'invention est aussi relative à un procédé de raccordement de deux dispositifs de coupure 100 raccordés par au moins un moyen de raccordement 10 tel que défini ci-dessus. Le procédé consiste à emboiter les deux extrémités 1 du moyen de raccordement sur les vis 101 des étriers 105 des bornes de raccordement 110 des deux dispositifs de coupure 100. Une fois l'emboitement terminé, le procédé consiste à imposer ensuite une rotation d'un angle de rotation α aux moyens de raccordement 10 autour de l'axe longitudinal X. Selon un mode particulier de réalisation du procédé, l'angle de rotation α appliqué aux moyens de raccordement 10 pour les faire passer de la première position d'emboitement à la seconde position de verrouillage est égale sensiblement à 90°.The invention also relates to a method of connecting two cut-off devices 100 connected by at least one connecting means 10 as defined above. The method consists in fitting the two ends 1 of the connecting means on the screws 101 of the stirrups 105 of the connecting terminals 110 of the two cut-off devices 100. Once the nesting is complete, the method consists in then imposing a rotation of a angle of rotation α to the connection means 10 around the longitudinal axis X. According to a particular embodiment of the method, the angle of rotation α applied to the connecting means 10 to move them from the first nesting position to the second locking position is substantially equal to 90 °.
