Description

L'invention est relative à un dispositif de fixation rapide et de plombage pour un cache-bornes d'un bottier d'un appareil électrique, comprenant une vis de fixation montée à rotation à fraction de tour sur le cache-bornes et portant à l'une de ses extrémités une tête de manoeuvre et à l'extrémité opposée un taquet susceptible de s'engager en position de fixation dans un logement conjugué de verrouillage ménagé dans ledit bottier.The invention relates to a quick fixing and sealing device for a terminal cover of a shoemaker of an electrical appliance, comprising a fixing screw mounted in rotation at fraction of a turn on the terminal cover and bearing the 'one of its ends a maneuvering head and at the opposite end a cleat capable of engaging in the fixing position in a conjugate locking housing formed in said case.

Les fixations rapides, notamment à quart de tour, facilitent le démontage ou l'ouverture et il a déjà été proposé de fixer des cache-bornes d'un appareil électrique par des vis à quart de tour. Le cache-bornes évite tout contact avec des pièces sous tension, et il permet en plus un plombage évitant tout accès aux bornes et de ce fait toute fraude. A cet effet, la vis présente un orifice de passage du fil de plombage passant par un orifice conjugué solidaire du cache-bornes. Lorsque la tête de la vis est noyée dans le cache-bornes la mise en place du fil de plombage est difficile et le fil peut être insuffisamment tendu pour éviter une rotation partielle de la vis parfois suffisante à la libération du cache-bornes et à son démontage. Cette fixation connue n'est donc pas infraudable et elle nécessite un tournevis pour la mise en place et l'enlèvement du cache-bornes.Quick fasteners, in particular quarter-turn, facilitate disassembly or opening and it has already been proposed to fix terminal covers of an electrical appliance by quarter-turn screws. The terminal cover avoids contact with live parts, and it also allows sealing to prevent access to the terminals and therefore fraud. To this end, the screw has a hole for the passage of the sealing wire passing through a conjugate hole secured to the terminal cover. When the screw head is buried in the terminal cover, it is difficult to place the sealing wire and the wire can be insufficiently stretched to avoid partial rotation of the screw, which is sometimes sufficient for the release of the terminal cover and its disassembly. This known attachment is therefore not flawless and it requires a screwdriver for the installation and removal of the terminal cover.

Un autre mode de fixation connu fait usage de simples vis nécessitant plusieurs tours de rotation pour la fixation et étant de ce fait infraudable. La manoeuvre de fixation est par contre longue et nécessite également un tournevis.Another known method of fixing makes use of simple screws requiring several rotational turns for fixing and therefore being tamper-proof. The fixing operation is however long and also requires a screwdriver.

La présente invention a pour but de remédier à ces inconvénients et de permettre la réalisation d'un dispositif de fixation rapide, simple et fiable.The present invention aims to remedy these drawbacks and allow the realization of a fast, simple and reliable fixing device.

Le dispositif de fixation selon l'invention est caractérisé en ce que ladite tête porte 'un levier de manoeuvre monté à basculement sur ladite tête de vis et qu'une rainure de logement dudit levier est ménagée dans ledit cache-bornes pour recevoir à insertion le levier et verrouiller le levier et la vis en position de fixation, l'ensemble étant agencé pour permettre une extraction du levier de ladite raiure par basculement et par la suite une rotation limitée du levier et de la vis associée pour dégager le taquet de son logement et désolidariser le chache-bornes du bottier.The fixing device according to the invention is characterized in that said head carries an operating lever pivotally mounted on said screw head and that a housing groove of said lever is formed in said terminal cover to receive the insertion lever and lock the lever and the screw in the fixing position, the assembly being arranged to allow the lever to be extracted from said groove by tilting and thereafter a limited rotation of the lever and of the associated screw to release the cleat from its housing and separate the terminal block from the bootmaker.

Le levier de manoeuvre est repliable dans une rainure du cache-bornes, et dans cette position repliée il verrouille la vis dans la position de fixation du cache-bornes sur le bottier de l'appareil électrique. Pour libérer le cache-bornes il suffit de basculer le levier hors de la rainure et de le faire tourner pour pivoter la vis d'un quart de tour vers la position de libération du cache-bornes. Ces opérations sont particulièrement simples et rapides et ne nécessitent aucun outil de manoeuvre. Le levier et la vis sont, selon un mode de mise en oeuvre préférentiel de l'invention, en une seule pièce moulée en matière plastique, l'articulation du levier étant réalisée par une partie amincie de liaison entre la tête de la vis et le levier.The operating lever is foldable in a groove in the terminal cover, and in this folded position it locks the screw in the position for fixing the terminal cover on the housing of the electrical appliance. To release the terminal cover, simply tilt the lever out of the groove and turn it to pivot the screw a quarter of a turn to the release position of the terminal cover. These operations are particularly simple and quick and do not require any operating tool. The lever and the screw are, according to a preferred embodiment of the invention, in a single piece molded from plastic, the articulation of the lever being produced by a thinned connecting part between the head of the screw and the the sink.

Selon un développement de l'invention, le fil de plombage retient le levier dans sa position repliée à l'intérieur de la rainure empêchant toute extraction de ce levier et de ce fait toute rotation de la vis. L'orifice de plombage est ménagé au voisinage de l'extrémité libre du levier qui effectue une course importante de basculement et de rotation pour la libération du cache-bornes.According to a development of the invention, the sealing wire retains the lever in its folded position inside the groove preventing any extraction of this lever and therefore any rotation of the screw. The sealing hole is formed in the vicinity of the free end of the lever which performs a large tilting and rotation stroke for the release of the terminal cover.

D'autres avantages et caractéristiques ressortiront plus clairement de la description qui va suivre d'un mode de mise en oeuvre de l'invention, donné à titre d'exemple non limitatif et représenté au dessin annexé, dans lequel :

  • - la figure 1 est une coupe partielle suivant la ligne I-I de la fig. 2, d'un cache-bornes équipé d'un dispositif de fixation selon l'invention, représenté en position de fixation;
  • - la figure 2 est une vue en plan de la fig. 1;
  • - la figure 3 est une coupe suivant la ligne III-III de la fig. 1, montrant la vis de fixation engagé dans le logement correspondant du bottier de l'appareil électrique;
  • - la figure 4 est une vue analogue à celle de la fig. 3, montrant la vis de fixation en position dégagée.
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 in the appended drawing, in which:
  • - Figure 1 is a partial section along line II of FIG. 2, a terminal cover fitted with a fixing device according to the invention, shown in the fixing position;
  • - Figure 2 is a plan view of fig. 1;
  • - Figure 3 is a section along line III-III of FIG. 1, showing the fixing screw engaged in the corresponding housing of the boot of the electrical appliance;
  • - Figure 4 is a view similar to that of FIG. 3, showing the fixing screw in the released position.

Sur les figures, un cache-bornes 10 en forme de capot susceptible de coiffer les bornes d'un appareil électrique, notamment les bornes d'un disjoncteur électrique, comporte une vis 12 de fixation susceptible de coopérer avec une partie conjuguée 13 du bottier du disjoncteur. La vis 12 du type à quart de tour est montée à rotation dans un logement 14 ménagé dans le cache-bornes 10, la tête 16 de la vis 12 étant noyée dans un creux 18 de la face du cache-bornes. L'extrémité opposée de la vis 12 porte un taquet 20 s'engageant dans la partie conjuguée 13 pour fixer le cache-bornes 10 au bottier. (voir fig. 3). Une rotation d'un quart de tour de la vis 12 dégage le taquet 20 en brisant la liaison entre le cache-bornes et le bottier. A la tête 16 est arti- culé un levier de manoeuvre 22 susceptible de se débattre dans un plan diamétral de la vis 12 et de se replier à l'intérieur d'une rainure 24 ménagée dans le cache-bornes 10. La largeur de la rainure 24 est légèrement supérieure à la largeur du levier 22 pour empêcher toute rotation de l'ensemble levier 22, vis 12 en position insérée du levier dans la rainure 24. La vis 12 est maintenue dans son logement 14 par un nez fendu 26 s'étendant suivant l'axe de la vis 12 et venant se clipser dans un orifice conjugué du cache-bornes 10. L'ensemble vis 12, tête 16, taquet 20, levier 22 et nez 26 est constitué par une pièce monobloc moulée en matière plastique, l'articulation du levier 22 sur la tête 16 étant réalisée par une partie amincie 28. L'extrémité libre du levier 22 présente une languette 30 à bords repliés 32 venant coiffer une cloison transversale 34 disposée dans la rainure 24. La languette 30 et la cloison 34 sont pourvues d'orifices 36, 38 qui sont alignés en position repliée du levier 22 à l'intérieur de la rainure 24. Un fil de plombage (non représenté) peut traverser les orifices 36, 38, de façon à solidariser la languette 30 à la cloison 34 et empêcher tout soulèvement du levier 22 en direction d'extraction de la rainure 24. L'extrémité 32 facilite la préhension du levier 22 pour l'opération de sortie du levier. L'élasticité de l'articulation 28 sollicite le levier en position insérée dans la rainure 24, le maintien du levier pouvant de plus être renforcé par frottement ou clipsage.In the figures, a terminal cover 10 in the form of a cover capable of covering the terminals of an electrical appliance, in particular the terminals of an electric circuit breaker, comprises a fixing screw 12 capable of cooperating with a mating part 13 of the shoemaker circuit breaker. The screw 12 of the quarter-turn type is rotatably mounted in a housing 14 formed in the terminal cover 10, the head 16 of the screw 12 being embedded in a recess 18 on the face of the terminal cover. The opposite end of the screw 12 carries a cleat 20 engaging in the conjugate part 13 to fix the terminal cover 10 to the shoemaker. (see fig. 3). A rotation of a quarter turn of the screw 12 releases the cleat 20 by breaking the connection between the terminal cover and the shoemaker. At the head 16 is articulated - an operating lever 22 capable of struggling in a diametrical plane of the screw 12 and of being folded back inside a groove 24 formed in the terminal cover 10. The width of the groove 24 is slightly greater than the width of the lever 22 to prevent any rotation of the lever assembly 22, screw 12 in the inserted position of the lever in the groove 24. The screw 12 is held in its housing 14 by a split nose 26 s' extending along the axis of the screw 12 and being clipped into a conjugate orifice of the terminal cover 10. The set of screws 12, head 16, cleat 20, lever 22 and nose 26 is constituted by a single piece molded from material plastic, the articulation of the lever 22 on the head 16 being produced by a thinned part 28. The free end of the lever 22 has a tongue 30 with folded edges 32 covering a transverse partition 34 disposed in the groove 24. The tongue 30 and the partition 34 are provided with holes 36, 38 which are aligned in the folded position of the lever 22 inside the groove 24. A sealing wire (not shown) can pass through the holes 36, 38, so as to secure the tongue 30 to the partition 34 and prevent any lifting of the lever 22 in the direction of extraction of the groove 24. The end 32 facilitates the gripping of the lever 22 for the lever output operation. The elasticity of the articulation 28 urges the lever in the position inserted in the groove 24, the retention of the lever being able to be further reinforced by friction or clipping.

Le dispositif de fixation selon l'invention fonctionne de la manière suivante :

  • Dans la position de fixation, représentée à la figure 1, la vis 12 solidarise le cache-bornes 10 au bottier 13 du disjoncteur, le taquet 20 étant engagé dans la partie conjuguée du bottier du disjoncteur. Le levier 22 est inséré dans la rainure 24 et immobilise en rotation la vis 12. Le levier 22 peut être plombé dans cette position par simple introduction d'un fil de plombage dans les orifices 36,38. Pour enlever le cache-bornes 10 il suffit de rompre le fil de plombage et d'extraire le levier 22 de la rainure 24 par simple basculement de la manière indiquée par la flèche et en traits pointillés sur la figure 1. Dès que le levier 22 est extrait de la rainure 24 il est possible de le faire tourner en entraînant la vis 12 en rotation d'un quart de tour faisant sortir le taquet 20 et libérant le cache-bornes 10 du bottier 13. Cette opération ne nécessite aucun outil et est extrêmement rapide. La mise en place du cache-bornes 10 s'opère par une opération inverse de mise en place du cache-bornes 10 et de rotation de la vis 12 pour engager le taquet 20. Par la suite il suffit d'insérer le levier 22 dans la rainure 24 pour verrouiller la vis 12 de la manière précitée.
The fixing device according to the invention operates as follows:
  • In the fixing position, shown in FIG. 1, the screw 12 secures the terminal cover 10 to the case 13 of the circuit breaker, the cleat 20 being engaged in the conjugate part of the case of the circuit breaker. The lever 22 is inserted into the groove 24 and immobilizes the screw 12 in rotation. The lever 22 can be sealed in this position by simple introduction of a sealing wire into the orifices 36, 38. To remove the terminal cover 10, it suffices to break the sealing wire and extract the lever 22 from the groove 24 by simple tilting as indicated by the arrow and in dotted lines in FIG. 1. As soon as the lever 22 is extracted from the groove 24 it is possible to rotate it by driving the screw 12 in rotation by a quarter turn causing the cleat 20 to come out and releasing the terminal cover 10 from the shoemaker 13. This operation requires no tools and is extremely fast. The installation of the terminal cover 10 is effected by a reverse operation of the installation of the terminal cover 10 and rotation of the screw 12 to engage the cleat 20. Thereafter, it suffices to insert the lever 22 into the groove 24 to lock the screw 12 in the aforementioned manner.

La mise en place du fil de plombage est simple malgré qu'aucune partie de la vis 12 et du levier 22 ne vienne en saillie de la face du cache-bornes 10. La fixation peut bien entendu être réalisée par plusieurs vis 12 et l'invention est applicable à des fixations d'autres parties que des cache-bornes, en particulier de couvercles ou autres panneaux d'appareils électriques.The installation of the sealing wire is simple despite the fact that no part of the screw 12 and of the lever 22 protrudes from the face of the terminal cover 10. The fixing can of course be carried out by several screws 12 and the The invention is applicable to fasteners from parts other than terminal covers, in particular from covers or other panels of electrical apparatus.
