Description

L'invention concerne le domaine des porte-fusibles.The invention relates to the field of fuse holders.

De manière connue, un porte-fusibles comprend une partie fixe, dans laquelle est monté au moins un dispositif mobile pour porte-fusibles qui reçoit un ou plusieurs fusibles, préférentiellement des fusibles de type NH ou des couteaux.In known manner, a fuse holder comprises a fixed part, in which is mounted at least one movable device for fuse holder which receives one or more fuses, preferably NH type fuses or knives.

Le document " EP 0 563 530 A1 " décrit un porte fusible selon le préambule de la revendication 1.The document " EP 0 563 530 A1 "describes a fuse holder according to the preamble of claim 1.

Par exemple, lorsque le porte-fusibles est destiné à une ligne monophasée, le porte-fusibles comprend un dispositif mobile qui est muni d'un seul fusible ou lorsque le porte-fusibles est destiné à une ligne triphasée, le porte-fusibles comprend un dispositif mobile qui est muni de trois fusibles.For example, when the fuse holder is for a single-phase line, the fuse holder includes a mobile device which is provided with a single fuse or when the fuse holder is for a three-phase line, the fuse holder includes a mobile device that has three fuses.

Plus particulièrement, le dispositif mobile comprend, d'une part, un couvercle, comprenant au moins une zone de réception apte et destinée à recevoir au moins un fusible et, d'autre part, des moyens d'actionnement, montés mobiles ou fixes par rapport audit couvercle, qui sont agencés pour manipuler le couvercle.More particularly, the mobile device comprises, on the one hand, a cover, comprising at least one reception zone suitable and intended to receive at least one fuse and, on the other hand, actuation means, mounted mobile or fixed by report to said cover, which are arranged to manipulate the cover.

De plus, le couvercle est, quant à lui prévu pour être monté, mobile en translation ou en rotation par rapport à ladite partie fixe, entre au moins :

  • une première position de fermeture, correspondant à un état de connexion du fusible avec des contacts, dans laquelle le couvercle est reçu dans la partie fixe,
  • une deuxième position d'ouverture, correspondant à un état de sectionnement du fusible avec les contacts, dans laquelle le couvercle est saillant de la partie fixe.
In addition, the cover is, for its part, designed to be mounted, movable in translation or in rotation with respect to said fixed part, between at least:
  • a first closed position, corresponding to a state of connection of the fuse with contacts, in which the cover is received in the fixed part,
  • a second open position, corresponding to a state of disconnection of the fuse with the contacts, in which the cover protrudes from the fixed part.

De la deuxième position d'ouverture, le couvercle peut alors ensuite passer vers :

  • une troisième position de maintenance, correspondant à un état de sectionnement du fusible avec les contacts dans lequel la reconnexion du fusible avec les contacts est non autorisée, dans laquelle le couvercle est saillant de la partie fixe et peut être immobilisé par rapport à la partie fixe, ou
  • une quatrième position de sortie, dans laquelle le couvercle est hors de la partie fixe et est libre par rapport à celle-ci.
From the second open position, the cover can then move to:
  • a third maintenance position, corresponding to a state of disconnection of the fuse with the contacts in which reconnection of the fuse with the contacts is not authorized, in which the cover protrudes from the fixed part and can be immobilized with respect to the fixed part , or
  • a fourth exit position, in which the cover is outside the fixed part and is free with respect to the latter.

Dans la troisième position de maintenance, le couvercle est préférentiellement immobilisé par rapport à la partie fixe, afin d'indiquer qu'une intervention est en cours sur la ligne et d'empêcher le réarmement du fusible avec les contacts par inadvertance.In the third maintenance position, the cover is preferably immobilized relative to the fixed part, in order to indicate that an intervention is in progress on the line and to prevent inadvertent resetting of the fuse with the contacts.

Dans la quatrième position de sortie, des opérations de maintenance sur le porte-fusibles peuvent être réalisées, notamment pour permettre le remplacement du ou des fusibles endommagés.In the fourth output position, maintenance operations on the fuse holder can be carried out, in particular to allow the replacement of the damaged fuse (s).

À l'heure actuelle, pour faire passer le couvercle dans la troisième position de maintenance, il est nécessaire de manipuler les moyens d'actionnement et d'autres organes de verrouillage annexes. Ces manipulations sont complexes, peu intuitives et peu ergonomiques pour l'opérateur. En effet, il est souvent nécessaire d'utiliser deux mains pour enclencher, faire pivoter ou translater les différentes pièces. En outre, des explications de fonctionnement doivent être détaillées à l'opérateur, afin qu'il puisse manipuler le porte-fusibles.At present, in order to move the cover into the third maintenance position, it is necessary to manipulate the actuating means and other related locking members. These operations are complex, not very intuitive and not very ergonomic for the operator. Indeed, it is often necessary to use two hands to engage, rotate or translate the different parts. In addition, explanations of operation must be detailed to the operator, so that he can handle the fuse holder.

Par ailleurs, pour des raisons de sécurité, la troisième position de maintenance doit pouvoir être consignée, par exemple au moyen d'un ou de plusieurs cadenas. De cette façon, il est possible d'éviter la manipulation par un autre opérateur du porte-fusibles, notamment lorsque la ligne électrique en aval est en maintenance. De même, la première position de fermeture doit pouvoir être bloquée pour éviter la manipulation du porte-fusibles sous charge, par exemple par du personnel non autorisé.Furthermore, for security reasons, the third maintenance position must be able to be logged, for example by means of one or more padlocks. In this way, it is possible to avoid the manipulation by another operator of the fuse holder, in particular when the downstream electrical line is under maintenance. Likewise, the first closed position must be able to be blocked to prevent manipulation of the fuse holder under load, for example by unauthorized personnel.

Pour cadenasser le porte-fusibles dans la troisième position de maintenance ou dans la première position de fermeture, des pièces additionnelles sont le plus souvent rajoutées pour permettre de fixer un unique cadenas, alors qu'au moins trois emplacements pour cadenas devraient idéalement être prévus.To padlock the fuse holder in the third maintenance position or in the first closed position, additional parts are most often added to allow a single padlock to be attached, while at least three padlock locations should ideally be provided.

La présente invention a pour but de pallier ces inconvénients en proposant un porte-fusibles de conception améliorée, ergonomique, simplifiée pour permettre une manipulation aisée et intuitive du porte-fusibles.The object of the present invention is to overcome these drawbacks by proposing a fuse holder of improved design, ergonomic, simplified to allow easy and intuitive handling of the fuse holder.

  • les moyens d'actionnement comprennent :
    • un levier comprenant deux bras, reliés entre eux par un élément de rigidification transversal, présentant chacun, d'une part, une première extrémité libre munie d'une première portion de la première liaison pivot et d'autre part, d'une deuxième extrémité,

According to the invention, the fuse holder 1 is characterized in that:
  • the lever 11 is movable in rotation relative to said cover 5 by means of the first pivot connection 8 about the first axis of rotation A1, so that:
    • in the first closed position PON, the second end 16 of the lever 11 is pivoted by a reference angle α0 preferably substantially equal to zero with respect to the external face 5 'of the cover 5 ( figure 1 ),
    • in the second opening position POFF, the second end 16 of the lever 11 is pivoted by a first angle α1 strictly greater than zero with respect to the external face 5 'of the cover 5 ( figure 3 ),
    • in the third PPARK maintenance position, the second end 16 of the lever 11 is pivoted by the reference angle α0 preferably substantially equal to zero with respect to the external face 5 'of the cover 5 ( figure 7 ),
    • the passage from the first closed position PON to the second open position POFF being done at least by rotational movement of the lever 11 around the first axis of rotation A1 in a clockwise direction +, and
    • the passage from the second opening position POFF to the third maintenance position PPARK being done by a rotational movement of the lever 11 around the first axis of rotation A1 in a counterclockwise direction -,
  • and in that :
    • the two lateral faces 6 of the cover 5 each comprise elastic return means 19, controlled by the lever 11 and suitable and intended for cooperate with a locking housing 20 arranged in the fixed part 2, the elastic return means 19 being arranged for:
    • in the first closed position PON, cooperate with at least one movable bearing portion 21 in rotation about the first axis of rotation A1 connected to the lever 11, so that the elastic return means 19 are constrained by the bearing portion movable 21 and that a locking end piece 22 connected to the elastic return means 19 is disposed outside the locking housing 20 of the fixed part 2 ( figures 1, 2 and 8 ),
    • in the second opening position POFF, cooperate with at least one movable reservation 23 in rotation about the first axis of rotation A1 connected to the lever 11, so that the elastic return means 19 are at least partly disposed in the mobile reservation 23 and that the locking end piece 22 is disposed outside the locking housing 20 of the fixed part 2 ( figures 3 and 4 ),
    • in the third PPARK maintenance position, cooperate, on the one hand, with the movable bearing portion 21, so that the elastic return means 19 are constrained by the movable bearing portion 21 and that the locking tip 22 is inserted into said locking housing 20, to immobilize the cover 5 with respect to the fixed part 2 ( figures 7 and 8 ).

Avantageusement, dans cette configuration la manipulation des moyens d'actionnement 7 par l'utilisateur est améliorée et intuitive. Plus particulièrement, pour faire passer le couvercle 5 dans les différentes positions, seule la manipulation de l'élément de préhension 17 est nécessaire et peut se faire à une seule main. En outre, aucune autre pièce additionnelle ne doit être manipulée par l'utilisateur. Pour passer de la première position de fermeture PON à la deuxième position d'ouverture POFF, il suffit de pivoter le levier 11 à l'aide de l'élément de préhension 17 dans le sens horaire +. Il en résulte que les premiers éléments de guidage linéaire 10 du couvercle 5 coulissent le long des premiers moyens de guidage linéaire 9 des deux parois latérales 3 de la partie fixe 2 et ainsi, le couvercle 5 est déplacé en translation relativement à la partie fixe 2. Ultérieurement, il suffit de pivoter le levier 11, à l'aide de l'élément de préhension 17, dans le sens antihoraire - pour atteindre la troisième position de maintenance PPARK. Par ailleurs, la position des moyens élastiques de rappel 19 est pilotée par le levier 11 par l'intermédiaire de la portion d'appui 21 et de la réservation mobile 23. En particulier, la portion d'appui mobile 21 permet d'éloigner l'embout de verrouillage 22 de sa position initiale, alors que la réservation mobile 23 permet le retour de l'embout de verrouillage 22 dans sa position initiale, qui peut correspondre à une position non contrainte des moyens élastiques de rappel 19. Ainsi, dans la première position de fermeture PON, même si la portion d'appui mobile 21 exerce une force d'appui sur les moyens élastiques de rappel 19, l'embout de verrouillage 22 n'est pas engagé dans le logement 20, car ces derniers ne sont pas en face l'une de l'autre. Par ailleurs, dans la deuxième position d'ouverture POFF, la portion d'appui mobile 21 n'appuie pas sur les moyens élastiques de rappel 19 et l'embout de verrouillage 22 n'est pas en face du logement de verrouillage 20 et ne s'engage pas dans ce dernier. Enfin, dans la troisième position de maintenance PPARK, l'embout de verrouillage 22 et le logement de verrouillage 20 sont en regard l'un de l'autre, et comme la portion d'appui mobile 21 vient en appui sur les moyens élastiques de rappel 19, l'embout de verrouillage 22 s'engage dans le logement de verrouillage 20 (figures 7 et 8). Il en résulte que le couvercle 5 est relié fixement à la partie fixe 2 du porte-fusibles 1 et est bloqué dans cette troisième position de maintenance PPARK. Ainsi, le dispositif mobile 4 est sécurisé sur la partie fixe 2, puisque le dispositif mobile 4 ne peut être retiré de la partie fixe 2. En outre, un retour vers la première position de fermeture PON n'est possible que par une action volontaire de l'utilisateur.Advantageously, in this configuration, the handling of the actuating means 7 by the user is improved and intuitive. More particularly, to move the cover 5 into the different positions, only the manipulation of the gripping element 17 is necessary and can be done with one hand. In addition, no other additional part should be manipulated by the user. To go from the first closed position PON to the second open position POFF, it suffices to pivot the lever 11 using the gripping element 17 clockwise +. It follows that the first linear guide elements 10 of the cover 5 slide along the first linear guide means 9 of the two side walls 3 of the fixed part 2 and thus the cover 5 is moved in translation relative to the fixed part 2 Subsequently, it suffices to pivot the lever 11, using the gripping element 17, counterclockwise - to reach the third maintenance position. PPARK. Furthermore, the position of the elastic return means 19 is controlled by the lever 11 via the support portion 21 and the mobile reservation 23. In particular, the mobile support portion 21 makes it possible to move away the 'locking end piece 22 from its initial position, while the mobile reservation 23 allows the locking end piece 22 to return to its initial position, which may correspond to an unconstrained position of the elastic return means 19. Thus, in the first PON closed position, even if the movable bearing portion 21 exerts a bearing force on the elastic return means 19, the locking end piece 22 is not engaged in the housing 20, because the latter are not not opposite each other. Furthermore, in the second opening position POFF, the movable bearing portion 21 does not press on the elastic return means 19 and the locking end piece 22 is not opposite the locking housing 20 and does not not engage in the latter. Finally, in the third PPARK maintenance position, the locking end piece 22 and the locking housing 20 are facing each other, and as the movable bearing portion 21 bears on the elastic means of recall 19, the locking end piece 22 engages in the locking housing 20 ( figures 7 and 8 ). The result is that the cover 5 is fixedly connected to the fixed part 2 of the fuse holder 1 and is locked in this third PPARK maintenance position. Thus, the mobile device 4 is secured on the fixed part 2, since the mobile device 4 cannot be withdrawn from the fixed part 2. In addition, a return to the first closed position PON is only possible by a voluntary action. of the user.

De préférence, chaque première extrémité libre 14 du levier 11 est munie d'un deuxième élément de guidage 24, le levier 11 étant guidé par des deuxièmes moyens de guidage 25, prévus dans chaque paroi latérale 3 de la partie fixe 2, coopérant avec le deuxième élément de guidage 24 du levier 11, de sorte que dans la position de fermeture PON, la deuxième extrémité 16 du levier 11 soit pivotée de l'angle de référence α0 (figure 1) et que dans la deuxième position d'ouverture POFF, la deuxième extrémité 16 du levier 11 soit pivotée du premier angle α1 (figure 3).Preferably, each first free end 14 of the lever 11 is provided with a second guide element 24, the lever 11 being guided by second guide means 25, provided in each side wall 3 of the fixed part 2, cooperating with the second guide element 24 of lever 11, so that in the closed position PON, the second end 16 of lever 11 is rotated by the reference angle α0 ( figure 1 ) and that in the second opening position POFF, the second end 16 of the lever 11 is pivoted by the first angle α1 ( figure 3 ).

Avantageusement, la coopération des deuxièmes moyens de guidage 25 du levier 11 et des deuxièmes éléments de guidage 24 de la partie fixe 2 permet de limiter le mouvement de rotation du levier 11. Ainsi, lorsque l'utilisateur pivote le levier 11 pour passer de la première position de fermeture PON à la deuxième position d'ouverture POFF, la rotation du levier 11 s'interrompt lorsque le levier 11 est pivoté du premier angle α1. Ainsi, l'utilisateur est averti que la deuxième position d'ouverture POFF est atteinte et qu'il est inutile de continuer à manipuler le levier 11.Advantageously, the cooperation of the second guide means 25 of the lever 11 and of the second guide elements 24 of the fixed part 2 makes it possible to limit the rotational movement of the lever 11. Thus, when the user pivots the lever 11 to move from the first closed position PON to the second open position POFF, the rotation of the lever 11 is interrupted when the lever 11 is rotated by the first angle α1. Thus, the user is warned that the second opening position POFF has been reached and that there is no point in continuing to manipulate the lever 11.

De préférence, les deuxièmes moyens de guidage 25 comprennent des moyens d'arrêt agencés de sorte que le passage de la deuxième position d'ouverture POFF vers la troisième position de maintenance PPARK ou, le cas échéant, vers une quatrième position de sortie POUT, se fait après passage dans une position intermédiaire de blocage PINT, lors duquel la deuxième extrémité 16 du levier 11 est agencée pour être pivotée du premier angle α1 et le couvercle 5 est agencé pour être mobile en translation par rapport à ladite partie fixe 2, selon la direction perpendiculaire à l'axe longitudinal L1, dans la position intermédiaire de blocage PINT, le deuxième élément de guidage 24 venant buter contre les moyens d'arrêt (figure 5).Preferably, the second guide means 25 comprise stop means arranged so that the passage from the second opening position POFF to the third maintenance position PPARK or, where appropriate, to a fourth output position POUT, is done after passing into an intermediate locking position PINT, during which the second end 16 of the lever 11 is arranged to be pivoted by the first angle α1 and the cover 5 is arranged to be movable in translation relative to said fixed part 2, according to the direction perpendicular to the longitudinal axis L1, in the intermediate locking position PINT, the second guide element 24 abuts against the stop means ( figure 5 ).

Avantageusement, de la deuxième position d'ouverture POFF, l'utilisateur peut tirer sur l'élément de préhension 17 dans la direction perpendiculaire à l'axe longitudinale L1 dans un sens de retrait du dispositif mobile 4 relativement à la partie fixe 2 et le couvercle 5 est alors déplacé en translation en étant guidé par les premiers moyens de guidage linéaire 9 coopérant avec les premiers éléments de guidage linéaire 10, jusqu'à ce que le deuxième élément de guidage 24 vienne buter contre les moyens d'arrêt, indiquant que la position intermédiaire de blocage PINT est atteinte. Plus particulièrement, le levier 11 n'est pas pivoté davantage pendant cette translation, les deuxièmes moyens de guidage 25 et les deuxièmes éléments de guidage 24 sont agencés de sorte que de la deuxième position d'ouverture POFF à la position intermédiaire de blocage PINT, la deuxième extrémité 16 du levier 11 reste pivotée du premier angle α1. Ces moyens d'arrêt permettent de placer le couvercle 5 dans une position intermédiaire de blocage PINT pour indiquer à l'utilisateur que le levier 11 peut désormais être pivoté vers la troisième position de maintenance PPARK ou vers la quatrième position sortie POUT, qui sera décrite ci-après. Dans cette position intermédiaire de blocage PINT les moyens élastiques de rappel 19 sont agencés pour coopérer avec la réservation mobile 23, comme dans la deuxième position d'ouverture POFF (figure 6). Par ailleurs, cette position intermédiaire de blocage PINT correspond également à un état de sectionnement du fusible avec les contacts.Advantageously, from the second opening position POFF, the user can pull on the gripping element 17 in the direction perpendicular to the longitudinal axis L1 in a direction of withdrawal of the mobile device 4 relative to the fixed part 2 and the cover 5 is then moved in translation while being guided by the first linear guide means 9 cooperating with the first linear guide elements 10, until the second guide element 24 abuts against the stop means, indicating that the intermediate PINT locking position has been reached. More particularly, the lever 11 is not pivoted further during this translation, the second guide means 25 and the second guide elements 24 are arranged so that from the second opening position POFF to the intermediate locking position PINT, the second end 16 of the lever 11 remains pivoted by the first angle α1. These stop means make it possible to place the cover 5 in an intermediate locking position PINT to indicate to the user that the lever 11 can now be pivoted towards the third maintenance position PPARK or towards the fourth extended position POUT, which will be described. below. In this intermediate PINT locking position, the elastic return means 19 are arranged to cooperate with the mobile reservation 23, as in the second opening position POFF ( figure 6 ). Moreover, this intermediate locking position PINT also corresponds to a state of disconnection of the fuse with the contacts.

De manière préférée, les deuxièmes moyens de guidage 25 comprennent une première rainure linéaire 26, préférentiellement s'étendant parallèlement à l'axe longitudinal L1, dans laquelle le deuxième élément de guidage 24 est logé dans la première position de fermeture PON (figure 1), et une deuxième rainure linéaire 27, préférentiellement s'étendant perpendiculairement à l'axe longitudinal L1, préférentiellement sensiblement à angle droit de la première rainure linéaire 26, dans laquelle le deuxième élément de guidage 24 est logé dans la deuxième position d'ouverture POFF (figure 3), et le cas échéant, dans la position intermédiaire de blocage PINT (figure 5).Preferably, the second guide means 25 comprise a first linear groove 26, preferably extending parallel to the longitudinal axis L1, in which the second guide element 24 is housed in the first closed position PON ( figure 1 ), and a second linear groove 27, preferably extending perpendicularly to the longitudinal axis L1, preferably substantially at right angles to the first linear groove 26, in which the second guide element 24 is housed in the second open position POFF ( figure 3 ), and if applicable, in the intermediate PINT locking position ( figure 5 ).

Ainsi, les deuxièmes éléments de guidage 24 coulissent le long des premières rainures linéaires 26, lors du passage de la première position de fermeture PON à la deuxième position d'ouverture POFF, jusqu'à venir atteindre la deuxième rainure linéaire 27 dans cette dernière position.Thus, the second guide elements 24 slide along the first linear grooves 26, during the passage from the first closed position PON to the second open position POFF, until reaching the second linear groove 27 in this last position .

De préférence, la deuxième rainure linéaire 27 débouche sur une butée 28 formant lesdits moyens d'arrêt, agencée pour empêcher le retrait de chaque première extrémité libre 14 du levier 11 des deuxièmes moyens de guidage 25 de la partie fixe 2.Preferably, the second linear groove 27 opens onto a stop 28 forming said stop means, arranged to prevent the withdrawal of each first free end 14 of the lever 11 from the second guide means 25 of the fixed part 2.

La butée 28 permet à la fois de signaler à l'utilisateur que le levier 11 peut être pivoté de la position intermédiaire de blocage PINT vers la troisième position de maintenance PPARK ou vers la quatrième position de sortie POUT, mais aussi d'empêcher que le dispositif mobile 4 ne soit retiré accidentellement de la partie fixe 2, lorsque l'utilisateur tire sur l'élément de préhension 17 dans la direction perpendiculaire à l'axe longitudinale L1, comme expliqué précédemment.The stop 28 makes it possible both to signal to the user that the lever 11 can be pivoted from the intermediate locking position PINT to the third maintenance position PPARK or to the fourth output position POUT, but also to prevent the mobile device 4 is accidentally removed from the fixed part 2, when the user pulls on the gripping element 17 in the direction perpendicular to the longitudinal axis L1, as explained above.

De préférence, la deuxième rainure linéaire 27 débouche, en outre, sur une première sortie 29, agencée pour autoriser le retrait de la première extrémité libre 14 du levier 11 des deuxièmes moyens de guidage 25 de la partie fixe 2, lors du passage de la deuxième position d'ouverture POFF à la troisième position de maintenance PPARK.Preferably, the second linear groove 27 opens, moreover, on a first outlet 29, arranged to allow the withdrawal of the first free end 14 of the lever 11 from the second guide means 25 of the fixed part 2, during the change from the second POFF opening position to the third PPARK maintenance position.

Cette première sortie 29 permet d'autoriser la rotation du levier 11 dans le sens antihoraire -, de sorte que les deuxièmes extrémités 16 du levier 11 puissent pivoter du premier angle α1 vers l'angle de référence α0, lors du passage de la deuxième position d'ouverture POFF en passant, le cas échéant, par la position intermédiaire de blocage PINT vers la troisième position de maintenance PPARK. De cette façon, dans la troisième position de maintenance PPARK, les premiers moyens de guidage linéaire 9 ne coopèrent plus avec les premiers éléments de guidage linéaire 10. Seuls les moyens élastiques de rappel 19 en coopération avec l'embout de verrouillage 22 et le logement de verrouillage 20 permettent le verrouillage du dispositif mobile 4 sur la partie fixe 2.This first output 29 allows the rotation of the lever 11 in the counterclockwise direction -, so that the second ends 16 of the lever 11 can pivot from the first angle α1 towards the reference angle α0, when passing from the second position POFF opening by passing, if necessary, through the intermediate locking position PINT to the third maintenance position PPARK. In this way, in the third PPARK maintenance position, the first linear guide means 9 no longer cooperate with the first linear guide elements 10. Only the elastic return means 19 in cooperation with the locking end piece 22 and the housing locking 20 allow the mobile device 4 to be locked on the fixed part 2.

De préférence, de la deuxième position d'ouverture POFF, le couvercle 5 est mobile en translation vers une quatrième position de sortie POUT (figure 9), dans laquelle, d'une part, le couvercle 5 est hors de la partie fixe 2 et est libre par rapport à la partie fixe 2 et, d'autre part, le levier 11 est mobile en rotation relativement audit couvercle 5 par l'intermédiaire de la première liaison pivot 8 autour du premier axe de rotation A1, de sorte que dans la quatrième position de sortie POUT, la deuxième extrémité 16 du levier 11 est pivotée par rapport à la face externe 5' du couvercle 5 d'un deuxième angle α2 strictement supérieur au premier angle α1, le passage de la deuxième position d'ouverture POFF à la quatrième position de sortie POUT se faisant au moins par mouvement rotation du levier 11 autour du premier axe de rotation A1 selon le sens horaire +.Preferably, from the second opening position POFF, the cover 5 is movable in translation towards a fourth output position POUT ( figure 9 ), in which, on the one hand, the cover 5 is outside the fixed part 2 and is free relative to the fixed part 2 and, on the other hand, the lever 11 is movable in rotation relative to said cover 5 by the 'intermediary of the first pivot link 8 around the first axis of rotation A1, so that in the fourth output position POUT, the second end 16 of the lever 11 is pivoted relative to the outer face 5' of the cover 5 by a second angle α2 strictly greater than the first angle α1, the passage from the second opening position POFF to the fourth output position POUT being done at least by rotating movement of the lever 11 around the first axis of rotation A1 in the clockwise direction +.

Avantageusement, dans cette configuration seule la manipulation de l'élément de préhension 17 est nécessaire et peut se faire à une seule main. En outre, aucune autre pièce additionnelle ne doit être manipulée par l'utilisateur. Après avoir franchi la deuxième position d'ouverture POFF, il suffit de pivoter le levier 11 à l'aide de l'élément de préhension 17 dans le sens horaire + pour atteindre la quatrième position de sortie POUT. Dans la quatrième position de sortie POUT, les premiers moyens de guidage linéaire 9 et les premiers éléments de guidage linéaire 10 sont désengagés les uns des autres. Il en résulte que le dispositif mobile 4 est libre relativement à la partie fixe 2 du porte-fusibles 1. Ainsi, des opérations de remplacement/modification du ou des fusibles sont possibles.Advantageously, in this configuration only the manipulation of the gripping element 17 is necessary and can be done with one hand. In addition, no other additional part should be manipulated by the user. After having crossed the second opening position POFF, it suffices to pivot the lever 11 using the gripping element 17 clockwise + to reach the fourth output position POUT. In the fourth output position POUT, the first linear guide means 9 and the first linear guide elements 10 are disengaged from each other. The result is that the mobile device 4 is free relative to the fixed part 2 of the fuse holder 1. Thus, replacement / modification operations of the fuse (s) are possible.

De préférence, dans la quatrième position de sortie POUT, les moyens élastiques de rappel 19 sont agencés pour coopérer avec la réservation mobile 23, de sorte que les moyens élastiques de rappel 19 sont au moins en partie disposés dans la réservation mobile 23 et que l'embout de verrouillage est disposé hors du logement de verrouillage 20 de la partie fixe 2 (figures 9 et 10).Preferably, in the fourth output position POUT, the elastic return means 19 are arranged to cooperate with the mobile reservation 23, so that the elastic return means 19 are at least partly disposed in the mobile reservation 23 and that the 'locking end is disposed outside the locking housing 20 of the fixed part 2 ( figures 9 and 10 ).

Avantageusement, la portion d'appui mobile 21 n'appuie pas sur les moyens élastiques de rappel 19 (figure 10). Par ailleurs, l'embout de verrouillage 22 n'est pas en face du logement de verrouillage 20 et ne s'engage pas dans ce dernier (figure 9).Advantageously, the movable bearing portion 21 does not press on the elastic return means 19 ( figure 10 ). Furthermore, the locking end piece 22 is not opposite the locking housing 20 and does not engage in the latter ( figure 9 ).

De préférence, la deuxième rainure linéaire 27, en outre, débouche sur une deuxième sortie 30, agencée pour autoriser le retrait de la première extrémité libre 14 du levier 11 des deuxièmes moyens de guidage 25 de la partie fixe 2, lors du passage de la deuxième position d'ouverture POFF à la quatrième position de sortie POUT.Preferably, the second linear groove 27, moreover, opens onto a second outlet 30, arranged to allow the withdrawal of the first free end 14 of the lever 11 from the second guide means 25 of the fixed part 2, during the passage of the second opening position POFF to fourth output position POUT.

Cette deuxième sortie 30 permet d'autoriser la rotation du levier 11 dans le sens horaire +, de sorte que les deuxièmes extrémités 16 du levier 11 puissent pivoter du premier angle α1 vers le deuxième angle α2, lors du passage de la deuxième position d'ouverture POFF en passant, le cas échéant, par la position intermédiaire de blocage PINT vers la quatrième position de sortie POUT. De cette façon, dans la quatrième position de sortie POUT, les premiers moyens de guidage linéaire 9 ne coopèrent plus avec les premiers éléments de guidage linéaire 10 (figure 9).This second output 30 allows the rotation of the lever 11 in the clockwise direction +, so that the second ends 16 of the lever 11 can pivot from the first angle α1 to the second angle α2, when passing from the second position of POFF opening by passing, if necessary, through the intermediate locking position PINT to the fourth output position POUT. In this way, in the fourth output position POUT, the first linear guide means 9 no longer cooperate with the first linear guide elements 10 ( figure 9 ).

De préférence, la réservation mobile 23 consiste en une encoche réalisée dans au moins une des premières extrémités libres 14.Preferably, the movable reservation 23 consists of a notch made in at least one of the first free ends 14.

Dans ce cas, lorsque les moyens élastiques de rappel 19 sont situés dans l'encoche, alors aucune contrainte n'est exercée sur les moyens élastiques de rappel 19 (figures 9 et 10).In this case, when the elastic return means 19 are located in the notch, then no stress is exerted on the elastic return means 19 ( figures 9 and 10 ).

De préférence, la réservation mobile 23 et la portion d'appui mobile 21 sont reliées entre elles par une rampe 31.Preferably, the movable reservation 23 and the movable bearing portion 21 are interconnected by a ramp 31.

De préférence, le logement de verrouillage 20 est aligné avec les premiers moyens de guidage linéaire 9 de la partie fixe 2.Preferably, the locking housing 20 is aligned with the first linear guide means 9 of the fixed part 2.

De préférence, le logement de verrouillage 20 consiste en une ouverture traversante.Preferably, the locking housing 20 consists of a through opening.

De préférence, le couvercle 5 comprend une barre transversale 33 escamotable mobile en translation entre une position escamotée PB1 (figures 1, 3, 5, 7 et 9), dans laquelle la barre transversale 33 repose sur la face externe 5' du couvercle 5, et une position sortie PB2 (figures 11 et 12), dans laquelle la barre transversale 33 est saillante de la face externe 5' et l'élément de rigidification 13 comprend une interface de contact 34 avec la barre transversale 23, venant en appui sur la barre transversale 33 en position sortie PB2, dans la première position de fermeture PON ou dans la troisième position de maintenance PPARK.Preferably, the cover 5 comprises a retractable transverse bar 33 movable in translation between a retracted position PB1 ( figures 1 , 3 , 5 , 7 and 9 ), in which the transverse bar 33 rests on the external face 5 'of the cover 5, and an extended position PB2 ( figures 11 and 12 ), in which the transverse bar 33 protrudes from the external face 5 'and the stiffening element 13 comprises a contact interface 34 with the transverse bar 23, bearing on the transverse bar 33 in the extended position PB2, in the first closed position PON or in the third maintenance position PPARK.

Dans cette configuration avantageuse, il est possible de verrouiller un ou plusieurs cadenas sur la barre transversale 33 placée en position sortie PB2 (figures 11 et 12). Le levier 11 peut ainsi être immobilisé par rapport au couvercle 5. Par conséquent, la rotation du levier 11/ des moyens d'actionnement 7 selon le premier axe de rotation A1 est empêchée, dans la première position de fermeture PON ou dans la troisième position de maintenance PPARK.In this advantageous configuration, it is possible to lock one or more padlocks on the transverse bar 33 placed in the extended position PB2 ( figures 11 and 12 ). The lever 11 can thus be immobilized relative to the cover 5. Consequently, the rotation of the lever 11 / of the actuating means 7 along the first axis of rotation A1 is prevented, in the first closed position PON or in the third position. PPARK maintenance program.

Ainsi, la première position de fermeture PON peut être bloquée pour éviter la manipulation du porte-fusibles sous charge, par exemple par du personnel non autorisé. En outre, la troisième position de maintenance PPARK peut être consignée pour éviter la manipulation par un autre utilisateur, par exemple lorsque la ligne électrique en aval est en maintenance.Thus, the first PON closed position can be blocked to prevent manipulation of the fuse holder under load, for example by unauthorized personnel. In addition, the third PPARK maintenance position can be logged to prevent manipulation by another user, for example when the downstream power line is under maintenance.

L'interface de contact 34 peut par exemple être comprise dans une ouverture traversante pouvant être traversée par la barre transversale 33 en position de sortie PB2.The contact interface 34 can for example be included in a through opening which can be crossed by the transverse bar 33 in the output position PB2.

Avantageusement, le fait de prévoir un élément de préhension 17 mobile entre la première position d'encombrement réduit P1 et la deuxième position relevée de travail P2 permet de réduire l'encombrement du dispositif mobile 4 lorsqu'aucune manipulation des moyens d'actionnement 7 ne doit être effectuée par un utilisateur. Par ailleurs, dans la première position de verrouillage PV1, l'élément de préhension 17 est verrouillé en position par les moyens de verrouillage et de déverrouillage 36. Ainsi, lorsque le dispositif mobile 4 est installé à la verticale, l'élément de préhension 17 ne peut pas pivoter autour du deuxième axe de rotation A2 sous l'effet de la gravité. Il en résulte que dans cette configuration, l'encombrement réduit du dispositif mobile 4 est garanti. De plus, les moyens de verrouillage et de déverrouillage 36 permettent à l'utilisateur de déverrouiller l'élément de préhension 11 de sa première position de verrouillage PV1 pour permettre sa rotation de la position d'encombrement réduit P1 vers la position relevée de travail P2. Les mêmes moyens de verrouillage et de déverrouillage 36 sont conçus pour verrouiller la position de l'élément de préhension 11, lorsque celui-ci atteint la position relevée de travail P2. Dans cette position relevée de travail P2 l'espace libre entre l'élément de préhension 17 et la face externe 5' du couvercle 5 est suffisant pour permettre l'introduction des doigts de l'utilisateur. Préférentiellement, cet espace libre est compris entre 20 millimètres et 27 millimètres. Il en résulte que l'utilisateur peut manipuler l'élément de préhension 17 de façon ergonomique. Enfin, lorsque plus aucune manipulation de l'élément de préhension 17 n'est nécessaire, les moyens de verrouillage et de déverrouillage 36 permettent à l'utilisateur de déverrouiller l'élément de préhension 17 de sa deuxième position de verrouillage PV2 pour permettre sa rotation de la position relevée de travail P2 vers la position d'encombrement réduit P1. Par ailleurs, comme les moyens de verrouillage et de déverrouillage 36 sont des parties intégrées au levier 11 et à l'élément de préhension 17, l'assemblage et la fabrication du dispositif mobile 4 est simplifiée.Advantageously, the fact of providing a gripping element 17 movable between the first position of reduced size P1 and the second raised working position P2 makes it possible to reduce the size of the mobile device 4 when no manipulation of the actuating means 7 is must be performed by a user. Furthermore, in the first locking position PV1, the gripping element 17 is locked in position by the locking and unlocking means 36. Thus, when the mobile device 4 is installed vertically, the gripping element 17 cannot pivot about the second axis of rotation A2 under the effect of gravity. As a result, in this configuration, the reduced size of the mobile device 4 is guaranteed. In addition, the locking and unlocking means 36 allow the user to unlock the gripping element 11 from its first locking position PV1 to allow its rotation from the reduced bulk position P1 to the raised working position P2 . The same locking and unlocking means 36 are designed to lock the position of the gripping element 11, when the latter reaches the raised working position P2. In this raised working position P2, the free space between the gripping element 17 and the external face 5 'of the cover 5 is sufficient to allow the introduction of the user's fingers. Preferably, this free space is between 20 millimeters and 27 millimeters. As a result, the user can handle the gripping element 17 ergonomically. Finally, when no further manipulation of the gripping element 17 is necessary, the locking and unlocking means 36 allow the user to unlock the gripping element 17 from its second locking position PV2 to allow its rotation. from the raised working position P2 to the reduced bulk position P1. Furthermore, as the locking and unlocking means 36 are parts integrated into the lever 11 and the gripping element 17, the assembly and manufacture of the mobile device 4 is simplified.
