Description

La présente invention concerne de façon générale une borne de raccordement pour un appareillage électrique de puissance, cette borne comprenant une cage qui forme une paroi latérale fermée qui entoure un logement de cage et une vis vissée au travers de la paroi latérale de la cage de façon à ce que son extrémité interne soit située dans le logement de cage.The present invention relates generally to a connection terminal for electrical power equipment, this terminal comprising a cage which forms a closed side wall which surrounds a cage housing and a screw screwed through the side wall of the cage so its internal end is located in the cage housing.

Dans la plupart des appareillages électriques de puissance, sont prévues des bornes de raccordement qui permettent de raccorder électriquement des câbles électriques à l'appareillage électrique de puissance. Par exemple, un disjoncteur de puissance peut compter au minimum deux bornes de raccordement destinées à être connectées respectivement à un câble d'arrivée et à un câble de départ du courant. Habituellement, une personne chargée de l'installation de ces appareillages électriques de puissance monte chaque appareillage électrique sur un support fixe, dénude l'extrémité d'un câble électrique, enfile cette extrémité dans un logement de bornes et visse une vis de borne jusqu'à son blocage afin d'établir une liaison mécanique et électrique efficaces entre le câble électrique et la borne de raccordement. La personne chargée d'une telle installation, appelée par la suite installateur, doit faire attention à exercer un couple de serrage sur la vis qui ne soit ni trop faible ni trop fort. Si le serrage de la vis est trop faible, il y a un risque de déconnexion du câble ou un risque de mauvais contact électrique et si le couple de serrage est trop fort, celui-ci peut détériorer les parties généralement en matière plastique qui supportent la borne de raccordement ou peut provoquer un matage trop important de la partie dénudée du câble, ce matage pouvant aller jusqu'à un affaiblissement de la section du câble susceptible de provoquer sa rupture.In most electrical power equipment, connection terminals are provided which allow electrical cables to be electrically connected to electrical power equipment. For example, a power circuit breaker can have at least two connection terminals intended to be connected respectively to an incoming cable and to a current starting cable. Usually, a person in charge of the installation of these electrical apparatuses of power mounts each electrical apparatus on a fixed support, strips the end of an electric cable, threads this end in a housing of terminals and screws a terminal screw until when locked to establish an efficient mechanical and electrical connection between the electrical cable and the connection terminal. The person in charge of such an installation, subsequently called the installer, must take care to exert a tightening torque on the screw which is neither too weak nor too strong. If the tightening of the screw is too weak, there is a risk of cable disconnection or a risk of poor electrical contact and if the tightening torque is too high, this can deteriorate the generally plastic parts which support the terminal of connection or can cause excessive matting of the stripped part of the cable, this matting can go as far as a weakening of the section of the cable which can cause it to break.

Il existe des dispositifs de raccordement qui permettent de raccorder un câble électrique sans utiliser de vis de serrage, ces dispositifs utilisant par contre une lame de ressort qui est recourbée. Pour raccorder une extrémité dénudée d'un câble électrique à ce dispositif de raccordement, la personne doit exercer une pression sur une partie de la lame de ressort afin de la faire fléchir élastiquement de façon à ce que l'extrémité dénudée du câble puisse être introduite entre une partie en forme de crochet ménagée au voisinage de l'extrémité libre de la lame de ressort et une partie fixe, de telle sorte que lorsque la personne relâche son action de pression sur la lame de ressort, celle-ci revient élastiquement en provoquant un pincement de l'extrémité dénudée du câble entre le crochet de la lame de ressort et la partie fixe afin d'établir une connexion électrique permanente entre le câble et le dispositif de raccordement. La force de pincement du câble est déterminée par la force de rappel de la lame de ressort, et cette force est par conséquent sensiblement constante et indépendante de la manière dont la personne agit sur le dispositif de raccordement. Un tel dispositif de raccordement connu présente l'inconvénient que le pincement de l'extrémité dénudée du câble s'effectue entre des zones quasi ponctuelles du crochet de la lame de resort et de la partie fixe, et ceci ne permet pas d'assurer un contact électrique suffisamment efficace pour pouvoir faire passer un courant intense. D'autre part, le courant électrique circule dans une partie de la lame de ressort et comme cette lame de ressort doit être réalisée généralement en un acier qui présente une résistivité relativement élevée, ceci diminue encore les possibilités d'utilisation d'un tel dispositif de raccordement pour des courants électriques denses. C'est pour ces raisons qu'un tel dispositif de raccordement n'a pu être utilisé jusqu'à présent que pour des appareillages électriques de faible puissance, par exemple pour des douilles pour ampoules électriques fonctionnant sous 220 V avec une puissance relativement faible de par exemple 100 W. Ces dispositifs de raccordement ont pu être également utilisés pour d'autres appareillages électriques basse-tension et faible puissance.There are connection devices which allow an electrical cable to be connected without using a clamping screw, these devices, on the other hand, use a spring leaf which is bent. To connect a stripped end of an electric cable to this connection device, the person must exert pressure on a part of the leaf spring in order to flex it elastically so that the stripped end of the cable can be introduced between a hook-shaped part formed in the vicinity of the free end of the spring leaf and a fixed part, so that when the person releases his pressure action on the spring leaf, the latter returns elastically causing pinching the stripped end of the cable between the hook of the spring leaf and the fixed part in order to establish a permanent electrical connection between the cable and the connection device. The cable clamping force is determined by the restoring force of the spring leaf, and this force is therefore substantially constant and independent of how the person acts on the connection device. Such a known connection device has the drawback that the pinching of the stripped end of the cable takes place between almost point areas of the hook of the resort blade and of the fixed part, and this does not ensure a electric contact sufficiently effective to be able to pass an intense current. On the other hand, the electric current flows in a part of the leaf spring and as this leaf spring must be generally made of a steel which has a relatively high resistivity, this further reduces the possibilities of using such a connection device for dense electric currents. It is for these reasons that such a connection device has so far been able to be used only for low power electrical equipment, for example for sockets for electric bulbs operating at 220 V with a relatively low power of for example 100 W. These connection devices could also be used for other low-voltage and low-power electrical equipment.

Pour des appareillages électriques de forte puissance (appelés par la suite simplement appareillages électriques de puissance), par exemple des appareillages électriques fonctionnant sous une tension élevée ou avec des courants intenses supérieurs à 1 Ampère, un tel dispositif de raccordement n'a jamais pu être utilisé de façon satisfaisante et il a été toujours nécessaire d'utiliser une borne de raccordement comprenant une vis destinée à être vissée jusqu'à être bloquée afin d'établir le contact électrique entre le câble et la borne.For high power electrical equipment (hereinafter simply called electrical power equipment), for example electrical equipment operating at high voltage or with high currents greater than 1 Ampere, such a connection device could never be used satisfactorily and it was always necessary to use a connection terminal comprising a screw intended to be screwed until it is blocked in order to establish the electrical contact between the cable and the terminal.

Un objet de la présente invention consiste à proposer une borne de raccordement pour appareillage électrique de puissance permettant d'assurer un contact électrique efficace entre le câble et la borne pouvant faire passer un courant électrique intense, la borne étant en outre conçue de façon à ce que l'installateur ne puisse pas effectuer un raccordement dans lequel le pincement du câble soit trop faible ou trop fort, en d'autres termes, que l'effort de serrage soit indépendant de l'installateur.An object of the present invention is to provide a connection terminal for electrical power equipment for ensuring effective electrical contact between the cable and the terminal capable of passing an intense electric current, the terminal being further designed so that that the installer cannot make a connection in which the cable pinching is too weak or too strong, in other words, that the clamping force is independent of the installer.

Un autre objet de l'invention consiste à proposer une telle borne de raccordement pouvant être actionnée par un installateur d'une façon plus commode et plus fiable afin d'effectuer une connexion ou une déconnexion d'un câble électrique.Another object of the invention consists in proposing such a connection terminal can be actuated by an installer in a more comfortable and reliable manner in order to make a connection or disconnection of an electric cable.

Un autre objet de l'invention consiste à proposer une telle borne de raccordement permettant en outre à un installateur de pouvoir contrôler aisément si cette borne de raccordement est connectée à un câble électrique ou n'est pas connectée à un câble électrique.Another object of the invention consists in proposing such a connection terminal allowing moreover an installer to be able to easily control whether this connection terminal is connected to an electric cable or is not connected to an electric cable.

Un autre objet de l'invention consiste à proposer une telle borne de raccordement pouvant être fixée sur un support approprié d'un appareillage électrique sans qu'une manoeuvre de la borne ne puisse entraîner une détérioration de ce support.Another object of the invention consists in proposing such a connection terminal which can be fixed on an appropriate support of an electrical apparatus without an operation of the terminal being able to cause a deterioration of this support.

L'invention concerne une borne de raccordement pour appareillage électrique de puissance, comprenant un cage qui forme une paroi latérale fermée qui entoure un logement de cage et une vis vissée au travers de la paroi latérale de la cage de façon à ce que son extrêmité interne soit située dans le logement de cage.The invention relates to a connection terminal for electrical power equipment, comprising a cage which forms a closed side wall which surrounds a cage housing and a screw screwed through the side wall of the cage so that its internal end is located in the cage housing.

Selon une caractéristique essentielle de l'invention, la borne de raccordement comprend en outre : une pièce de contact mobile logée dans le logement de cage de façon à pouvoir se déplacer dans le logement de cage, cette pièce de contact mobile formant un logement de câble destiné à recevoir un câble électrique ; un ressort de compression disposé dans un espace séparant une paroi interne de la cage et une paroi externe de la pièce de contact mobile, ce ressort étant situé à l'opposé de la vis de façon à pousser élastiquement la pièce de contact mobile contre l'extrémité interne de la vis, de telle sorte que l'actionnement de la vis dans un sens entraîne le déplacement de la pièce de contact mobile en comprimant le ressort et que l'actionnement de la vis dans le sens opposé entraîne le déplacement de la pièce de contact mobile en détendant le ressort ; et une surface de contact fixe disposée à proximité du câble électrique engagé dans la pièce de contact mobile, de telle sorte que l'actionnement de la vis dans le sens qui entraîne le déplacement de la pièce de contact mobile en détendant le ressort provoque le pincement du câble entre la pièce de contact mobile ; et la surface de contact fixe, la force de pincement étant fournie par la force élastique du ressort, et que l'actionnement de la vis dans le sens qui entraîne le déplacement de la pièce de contact mobile en comprimant le ressort provoque la libération du câble entre la pièce de contact mobile et la surface de contact fixe.According to an essential characteristic of the invention, the connection terminal further comprises: a movable contact part housed in the cage housing so as to be able to move in the cage housing, this movable contact part forming a cable housing intended to receive an electric cable; a compression spring disposed in a space separating an internal wall of the cage and an external wall of the movable contact piece, this spring being located opposite the screw so as to elastically push the movable contact piece against the internal end of the screw, so that actuation of the screw in one direction causes the movable contact piece to move by compressing the spring and that the actuation of the screw in the opposite direction causes the displacement of the movable contact piece by relaxing the spring; and a fixed contact surface disposed near the electric cable engaged in the movable contact piece, so that the actuation of the screw in the direction which causes the displacement of the movable contact piece by relaxing the spring causes the pinching cable between the movable contact piece; and the fixed contact surface, the gripping force being provided by the elastic force of the spring, and that the actuation of the screw in the direction which causes the displacement of the movable contact piece by compressing the spring causes the release of the cable between the movable contact piece and the fixed contact surface.

D'autres avantages et caractéristiques ressortiront plus clairement de la description qui va suivre d'un mode de réalisation de l'invention donné à titre d'exemple non limitatif et représenté par les dessins annexés parmi lesquels :

  • la figure 1 est une vue en coupe d'une borne de raccordement selon la présente invention ;
  • la figure 2 est une vue en coupe d'un autre mode de réalisation d'une borne de raccordement selon l'invention ; et
  • la figure 3 est une vue en coupe AA de la figure 2.
Other advantages and characteristics will emerge more clearly from the description which follows of an embodiment of the invention given by way of nonlimiting example and represented by the appended drawings among which:
  • Figure 1 is a sectional view of a connection terminal according to the present invention;
  • Figure 2 is a sectional view of another embodiment of a connection terminal according to the invention; and
  • FIG. 3 is a sectional view AA of FIG. 2.

Sur la figure 1, une borne de raccordement 1 pour appareillage électrique de puissance (non représenté) comprend une cage 2 qui forme une paroi latérale fermée 3 qui entoure un logement de cage 4. Une vis 5 est vissée au travers de la paroi latérale 3 de la cage 2 de façon à ce que son extrémité interne 6 soit située dans le logement de cage 4. Une pièce de contact mobile 7 est logée dans le logement de cage 4 de façon à pouvoir se déplacer latéralement dans le logement de cage 4, ce déplacement s'effectuant suivant une direction parallèle à l'axe longitudinal 8 de la vis 5. La pièce de contact mobile 7 comprend un trou 9 sensiblement dans sa partie centrale, ce trou étant de préférence cylindrique et étant orienté de telle sorte que son axe longitudinal 10 soit sensiblement perpendiculaire à l'axe longitudinal 8 de la vis 5. Un trou 11 est d'autre part ménagée au travers de la paroi latérale 3 de la cage 2, ce trou pouvant traverser de part en part toute la cage 2, comme cela est représenté sur la figure 1 ou pouvant simplement traverser un côté de la paroi latérale 3 (selon une variante non représentée). La vis 5 s'appuie au niveau de son extrémité interne 6 contre une face d'appui 12 de la pièce de contact mobile 7. La pièce de contact mobile 7 comprend en outre une face latérale 13 opposée à la face de contact 12, c'est-à-dire que la face latérale 13 est située dans la partie de la pièce de contact mobile 7 qui est la plus éloignée de la vis 5. Un ressort de compression 14 est logé entre la face latérale 13 de la pièce de contact mobile 7 et une face d'appui 15 située dans le logement de cage 4 de la cage 2. Un évidement de faible profondeur est ménagé au niveau de la face latérale 13 et un autre évidement de faible profondeur est ménagé au niveau de la face d'appui 15 de telle sorte que le ressort de compression 14 soit engagé respectivement dans l'un et l'autre de ces deux logements afin d'être maintenu latéral. Le ressort de compression 14 pousse en permanence la pièce de contact mobile 7 contre le vis 5. Si la vis 5 est complètement vissée, la pièce de contact mobile 7 est déplacée de façon à ce que sa face latérale 13 soit rapprochée de la face d'appui 15 en comprimant ainsi fortement le ressort de compression 14. Dans cette position (qui n'est pas représentée sur la figure 1), le trou 9 de la pièce de contact mobile est sensiblement aligné avec le trou 11 de la cage 2 et il est alors possible de faire passer au travers de ces deux trous une partie dénudée 16 d'un câble électrique 17, un jeu relativement important étant prévu entre la partie dénudée 16 et les deux trous 9 et 11 de façon à ce que cette partie dénudée 16 puisse être enfilée facilement. Ensuite, un installateur peut dévisser la vis 5 de façon à ce qu'elle se déplace vers l'extérieur de la cage 2, ce dévissage produisant un déplacement de la pièce de contact mobile 7 sous l'action du ressort de compression 14, ce déplacement suivant le déplacement de la vis 5 (ce déplacement de la pièce de contact mobile 7 s'effectuant vers le haut sur le dessin de la figure 1). Il se produit alors un pincement de la partie dénudée 16 du câble entre le trou 9 de la pièce de contact mobile 7 et le trou 11 de la cage 2. La force de pincement correspond exactement à la force de compression du ressort 14. Lorsque la pièce de contact mobile 7 pince ainsi la partie dénudée 16 de câble, elle est immobilisée et si l'installateur continue à dévisser la vis 5, l'extrémité interne 6 de la vis 5 s'écarte de la face d'appui 12 de la pièce de contact mobile 7 et la vis 5 n'agit plus sur la pièce de contact mobile 7. La borne de raccordement est alors dans une condition de connexion du câble électrique 17, cette position de connexion étant celle qui est représentée sur la figure 1. Dans cette position de connexion, la force de pincement de l'extrémité 16 du câble 17 est constante. Par conséquent cette force de pincement est indépendante de l'action qu'un installateur peut faire sur la vis 5. D'autre part, cette force de pincement peut être relativement importante parce qu'elle résulte d'un ressort de compression 14 qui peut être conçu de façon à développer une force relativement élevée. En effet, grâce au système de vis 5, une force relativement élevée du ressort 14 peut être vaincue facilement en actionnant la vis 5 de façon à la visser dans la cage 2 du fait que le système de vissage est capable de développer une force axiale relativement importante à partir d'un couple de vissage relativement faible.In FIG. 1, a connection terminal 1 for electrical power equipment (not shown) comprises a cage 2 which forms a closed side wall 3 which surrounds a cage housing 4. A screw 5 is screwed through the side wall 3 of the cage 2 so that its internal end 6 is located in the cage housing 4. A movable contact piece 7 is housed in the cage housing 4 so as to being able to move laterally in the cage housing 4, this movement taking place in a direction parallel to the longitudinal axis 8 of the screw 5. The movable contact piece 7 comprises a hole 9 substantially in its central part, this hole being preferably cylindrical and being oriented so that its longitudinal axis 10 is substantially perpendicular to the longitudinal axis 8 of the screw 5. A hole 11 is on the other hand formed through the side wall 3 of the cage 2, this hole that can pass right through the entire cage 2, as shown in Figure 1 or can simply pass through one side of the side wall 3 (according to a variant not shown). The screw 5 is supported at its internal end 6 against a bearing face 12 of the movable contact piece 7. The movable contact piece 7 further comprises a lateral face 13 opposite the contact face 12, c that is to say that the side face 13 is located in the part of the movable contact piece 7 which is the farthest from the screw 5. A compression spring 14 is housed between the side face 13 of the contact piece mobile 7 and a bearing face 15 located in the cage housing 4 of the cage 2. A shallow recess is provided at the side face 13 and another shallow recess is provided at the face d 'Support 15 so that the compression spring 14 is engaged respectively in one and the other of these two housings to be kept lateral. The compression spring 14 permanently pushes the movable contact piece 7 against the screw 5. If the screw 5 is completely screwed, the movable contact piece 7 is moved so that its lateral face 13 is brought closer to the face d support 15 thereby strongly compressing the compression spring 14. In this position (which is not shown in Figure 1), the hole 9 of the movable contact piece is substantially aligned with the hole 11 of the cage 2 and it is then possible to pass a portion of these two holes stripped 16 of an electric cable 17, a relatively large clearance being provided between the stripped part 16 and the two holes 9 and 11 so that this stripped part 16 can be threaded easily. Then, an installer can unscrew the screw 5 so that it moves towards the outside of the cage 2, this unscrewing producing a displacement of the movable contact piece 7 under the action of the compression spring 14, this displacement according to the displacement of the screw 5 (this displacement of the movable contact part 7 taking place upwards in the drawing of FIG. 1). There then occurs a pinching of the stripped part 16 of the cable between the hole 9 of the movable contact piece 7 and the hole 11 of the cage 2. The pinching force corresponds exactly to the compression force of the spring 14. When the movable contact piece 7 thus clamps the stripped part 16 of cable, it is immobilized and if the installer continues to unscrew the screw 5, the internal end 6 of the screw 5 moves away from the bearing face 12 of the movable contact piece 7 and the screw 5 no longer acts on the movable contact piece 7. The connection terminal is then in a condition for connection of the electric cable 17, this connection position being that which is shown in FIG. 1 In this connection position, the pinching force of the end 16 of the cable 17 is constant. Consequently, this gripping force is independent of the action that an installer can make on the screw 5. On the other hand, this gripping force can be relatively large because it results from a spring of compression 14 which can be designed to develop a relatively high force. Indeed, thanks to the screw system 5, a relatively high force of the spring 14 can be easily overcome by actuating the screw 5 so as to screw it into the cage 2 because the screw system is capable of developing a relatively axial force. important from a relatively low tightening torque.

Sur les figures 2 et 3, est représenté un autre mode de réalisation d'une borne de raccordement selon l'invention. Cette borne 20 comporte une cage 21 qui forme une paroi latérale fermée 22 qui entoure un logement de cage 23. Une vis 24 est vissée au travers de la paroi latérale 22 de la cage 21 de façon à ce que son extrémité interne 25 soit située à l'intérieur du logement de cage 23. Une pièce de contact 26 est montée de façon mobile à l'intérieur du logement de cage 23 et cette pièce de contact mobile 26 comporte un évidement 27. Une extrémité dénudée 16 d'un câble 17 peut être insérée dans l'évidement 27 de la pièce de contact mobile 26. D'autre part, une plage fixe 28, solidaire de la cage 21, s'étend en partie dans l'évidement 27 de la pièce de contact mobile 26 de telle sorte que l'extrémité dénudée 16 du câble 17 soit ensuite située entre une face d'appui 29 de l'évidement 27 et une surface de contact fixe 30 de la plage fixe 28. La surface de contact 29 est dirigée vers la vis 24 et la surface de contact fixe 30 est dirigée vers la surface de contact 29. Un ressort de compression 31 est disposé entre la pièce de contact mobile 26 et une surface d'appui interne 32 faisant partie du logement de cage 23. Le ressort de compression 31 pousse en permanence la pièce de contact mobile 26 en direction de la vis 24 et, lorsque la vis 24 est complètement vissée dans la cage 21, la pièce de contact mobile 26 est déplacée de façon à comprimer le ressort de compression 31 et de façon à ce que la surface de contact 29 de la pièce de contact mobile 26 et la surface de contact fixe 30 de la plage fixe 28 soient relativement écartées l'une de l'autre afin de pouvoir introduire avec un certain jeu l'extrémité dénudée 16 du câble 17. Ensuite, en dévissant la vis 24 de façon à ce qu'elle soit déplacée vers l'extérieur de la cage 21, on provoque le déplacement correspondant de la pièce de contact mobile 26 sous l'action du ressort de compression 31 et cela provoque le pincement de l'extrémité dénudée 16 du câble entre les surfaces 29 et 30. Dans ce mode de réalisation, la pièce qui est fixe par rapport à l'appareillage électrique est la plage fixe 28 alors que dans le premier mode de réalisation représenté sur la figure 1, la pièce fixe par rapport à l'appareillage électrique est la cage 2.FIGS. 2 and 3 show another embodiment of a connection terminal according to the invention. This terminal 20 comprises a cage 21 which forms a closed side wall 22 which surrounds a cage housing 23. A screw 24 is screwed through the side wall 22 of the cage 21 so that its internal end 25 is located at inside the cage housing 23. A contact piece 26 is movably mounted inside the cage housing 23 and this movable contact piece 26 has a recess 27. A stripped end 16 of a cable 17 can be inserted into the recess 27 of the movable contact piece 26. On the other hand, a fixed pad 28, integral with the cage 21, extends partially in the recess 27 of the movable contact piece 26 of such so that the stripped end 16 of the cable 17 is then located between a bearing face 29 of the recess 27 and a fixed contact surface 30 of the fixed area 28. The contact surface 29 is directed towards the screw 24 and the fixed contact surface 30 is directed towards the contact surface t 29. A compression spring 31 is disposed between the movable contact piece 26 and an internal bearing surface 32 forming part of the cage housing 23. The compression spring 31 permanently pushes the movable contact piece 26 in the direction of the screw 24 and, when the screw 24 is completely screwed into the cage 21, the movable contact piece 26 is moved from so as to compress the compression spring 31 and in such a way that the contact surface 29 of the movable contact piece 26 and the fixed contact surface 30 of the fixed pad 28 are relatively spaced from one another in order to being able to introduce with a certain clearance the stripped end 16 of the cable 17. Then, by unscrewing the screw 24 so that it is moved towards the outside of the cage 21, the corresponding movement of the contact piece is caused mobile 26 under the action of the compression spring 31 and this causes the stripped end 16 of the cable to be pinched between the surfaces 29 and 30. In this embodiment, the part which is fixed relative to the electrical equipment is the fixed surface 28 whereas in the first embodiment shown in FIG. 1, the fixed part with respect to the electrical equipment is the cage 2.

Afin d'éviter l'inconvénient d'avoir à visser la vis 5 (ou 24) pour désserrer le câble 17 et à dévisser la vis 5 (ou 24) pour serrer et connecter le câble 17 à la borne 1 (ou 20), on peut utiliser une vis 5 (ou 24) à pas à gauche.In order to avoid the inconvenience of having to screw the screw 5 (or 24) to loosen the cable 17 and to unscrew the screw 5 (or 24) to tighten and connect the cable 17 to terminal 1 (or 20), you can use a screw 5 (or 24) with left pitch.

Afin que l'installateur ne puisse pas perdre la vis 5 (ou 24) en la dévissant complètement, il peut être prévu sur la vis 5 (ou 24) un moyen d'arrêt pour empêcher que la vis ne soit déplacée vers l'extérieur au-delà d'une certaine limite. Ce moyen d'arrêt peut être constitué par exemple par un élargissement de l'extrémité interne 6 (ou 25) de la vis.So that the installer cannot lose the screw 5 (or 24) by unscrewing it completely, there can be provided on the screw 5 (or 24) a stop means to prevent the screw from being moved outwards beyond a certain limit. This stop means can be constituted for example by a widening of the internal end 6 (or 25) of the screw.

Afin qu'un installateur puisse constater visiblement si une extrémité dénudée 16 d'un câble 17 est serrée ou déserrée à l'intérieur de la borne de raccordement 1 (ou 20), la vis 5 (ou 24) peut comporter avantageusement un élément de visualisation pour que l'installateur puisse constater si elle est vissée ou dévissée. Cet élément de visualisation peut être constitué par exemple par une marque de couleur située dans une région de la vis qui est apparente lorsque la vis est dévissée, c'est-à-dire lorsque la vis est en position déplacée vers l'extérieur par rapport à la cage et invisible lorsque la vis est vissée, c'est-à-dire déplacée vers l'intérieur de la cage.So that an installer can visibly see if a stripped end 16 of a cable 17 is tightened or loosened inside the connection terminal 1 (or 20), the screw 5 (or 24) may advantageously include a display so that the installer can see whether it is screwed on or unscrewed. This display element can be constituted, for example, by a color mark located in a region of the screw which is visible when the screw is unscrewed, that is to say when the screw is in the position moved outward relative to to the cage and invisible when the screw is screwed, that is to say moved towards the inside of the cage.
