Description

La présente invention concerne un coupe-circuit manuel équipant un circuit électrique et permettant d'établir et d'interrompre l'alimentation électrique dudit circuit.The present invention relates to a manual circuit breaker fitted to an electrical circuit and making it possible to establish and interrupt the electrical supply of said circuit.

Les coupe-circuits, appelés également coupe-batterie sont couramment utilisés pour équiper des véhicules routiers et des bateaux à moteur qui comportent une batterie comme source d'alimentation électrique. En utilisation, le coupe-circuit est relié en général entre un circuit électrique principal du véhicule ou du bateau et la batterie qui l'alimente, et fonctionne comme un interrupteur électrique principal du circuit. L'utilisateur du véhicule ou du bateau équipé du coupe-circuit peut interrompre l'alimentation électrique du véhicule ou du bateau pendant la durée de son absence, ce qui permet d'éviter le déchargement de la batterie dû à des fuites électriques dans le circuit principal, et d'augmenter le facteur sécurité d'utilisation du véhicule ou du bateau en supprimant l'alimentation électrique. Une telle pratique est recommandée notamment pour le transport de matières dangereuses inflammables ou explosives dont les normes de sécurité sont réglementées de manière stricte.Circuit breakers, also called battery switches, are commonly used to equip road vehicles and motor boats that include a battery as a source of electrical power. In use, the circuit breaker is generally connected between a main electrical circuit of the vehicle or boat and the battery which supplies it, and functions as a main electrical switch of the circuit. The user of the vehicle or boat fitted with the circuit breaker can interrupt the power supply to the vehicle or the boat for the duration of his absence, which avoids discharging the battery due to electrical leaks in the circuit. main, and to increase the safety factor of use of the vehicle or the boat by eliminating the electric supply. Such a practice is recommended in particular for the transport of flammable or explosive dangerous materials whose safety standards are strictly regulated.

Les coupe-circuits comportent en général un boîtier qui enferme un mécanisme d'actionnement relié à une poignée de manoeuvre rotative. Le fond du boîtier est traversé par deux ou quatre plots électriques de contact qui sont reliés au circuit électrique principal et à la batterie d'alimentation. Le mécanisme d'actionnement est pourvu d'un ou de deux ponts électriques mobiles pouvant relier électriquement les plots de contact par paire. Lorsque la poignée de manoeuvre est actionnée, le ou les ponts électriques sont animés d'un mouvement de translation dans le boîtier en se rapprochant ou en s'éloignant des plots électriques de contact. Des ressorts de compression sont disposés axialement dans le boîtier pour appliquer le ou les ponts électriques sur les plots de contact afin d'établir la liaison électrique entre les plots d'une part, et de rappeler le ou les ponts électriques à la position de repos éloignée des plots électriques pour interrompre la liaison électrique entre les plots d'autre part.Circuit breakers generally include a housing which encloses an actuating mechanism connected to a rotary operating handle. Two or four electrical contact pads are passed through the bottom of the housing, which are connected to the main electrical circuit and to the supply battery. The actuation mechanism is provided with one or two movable electrical bridges capable of electrically connecting the contact pads in pairs. When the operating handle is actuated, the electrical bridge (s) are driven in a translational movement in the housing while approaching or away from the electrical contact pads. Compression springs are arranged axially in the housing to apply the electrical bridge (s) to the contact pads in order to establish the electrical connection between the pads on the one hand, and to bring the electrical bridge (s) back to the rest position. away from electrical contacts for interrupt the electrical connection between the pads on the other hand.

Actuellement, les coupe-circuits comprennent des mécanismes d'actionnement qui sont réalisés par l'assemblage d'un grand nombre de pièces en matériau métallique et non métallique. Il est nécessaire d'assurer une précision suffisante dans l'élaboration de ces différentes pièces afin de permettre leur assemblage avec une tolérance acceptable pour constituer le mécanisme d'actionnement du coupe-circuit.Currently, circuit breakers include actuation mechanisms which are produced by assembling a large number of parts made of metallic and non-metallic material. It is necessary to ensure sufficient precision in the development of these different parts in order to allow their assembly with an acceptable tolerance to constitute the actuating mechanism of the circuit breaker.

De plus, les poignées de manoeuvre ne sont pas souvent conçues pour être amovibles du boîtier du coupe-circuit. Dans certains cas, la poignée de manoeuvre est rendue amovible uniquement dans une position de coupure électrique du coupe-circuit. Ces poignées amovibles sont réalisées en matériau métallique avec le mécanisme d'actionnement incorporé. Il en résulte qu'une telle poignée amovible est lourde et peut être égarée facilement puisque l'utilisateur ne la porte pas sur lui. En cas d'utilisation dans un bateau, il existe un risque supplémentaire puisque la poignée amovible qui tombe dans l'eau est pratiquement irrécupérable par l'utilisateur.In addition, the operating handles are not often designed to be removable from the circuit breaker housing. In certain cases, the operating handle is made removable only in an electrical cut-out position of the circuit breaker. These removable handles are made of metallic material with the incorporated actuation mechanism. As a result, such a removable handle is heavy and can be easily lost since the user does not carry it with him. When used in a boat, there is an additional risk since the removable handle that falls into the water is practically irrecoverable by the user.

La présente invention a pour objet un coupe-circuit de structure simple et à faible prix de revient.The present invention relates to a circuit breaker of simple structure and at low cost price.

L'invention a également pour objet un coupe-circuit dont la poignée de manoeuvre est allégée et amovible aussi bien en position en ON (établissement du contact électrique entre une paire de plots à l'aide d'un pont électrique) qu'en position OFF (suppression de contact électrique entre les plots) du coupe-circuit.The invention also relates to a circuit breaker whose operating handle is lightened and removable both in position ON (establishment of electrical contact between a pair of studs using an electric bridge) and in position OFF (suppression of electrical contact between the pads) of the circuit breaker.

L'invention a en outre pour objet de fournir une indication de l'état de fonctionnement (ON ou OFF) du coupe-circuit lorsque la poignée de manoeuvre est enlevée du boîtier, à l'aide d'un organe intermédiaire monté dans le boîtier du coupe-circuit et actionné par la poignée de manoeuvre.The object of the invention is further to provide an indication of the operating state (ON or OFF) of the circuit breaker when the operating handle is removed from the housing, using an intermediate member mounted in the housing. of the circuit breaker and actuated by the operating handle.

L'invention a encore pour objet un coupe-circuit avec une poignée de manoeuvre réalisée en matériau léger pouvant flotter sur l'eau et pouvant servir de porte-clés pour regrouper les clés du véhicule ou du bateau.Another subject of the invention is a circuit breaker with an operating handle made of light material which can float on water and which can serve as a key holder for grouping the keys of the vehicle or of the boat.

Le coupe-circuit selon l'invention comprend une poignée de manoeuvre rotative, un boîtier avec un couvercle et une embase assemblée de façon étanche et enfermant une cage à ressort mobile axialement, des ressorts axiaux associés à la cage, et un organe intermédiaire d'actionnement actionné par la poignée de manoeuvre pour agir axialement sur la cage à ressort mobile. L'embase est pourvue d'au moins deux plots électriques de contact. Selon l'invention, la cage à ressort comprend un axe de support pourvu d'une ouverture diamétrale pour recevoir un pont électrique, et un ressort principal qui agit axialement contre le pont électrique pour le plaquer au fond de l'ouverture diamétrale de l'axe de support. Lorsqu'on actionne la poignée de manoeuvre à partir de la position "OFF" de coupure électrique, l'organe intermédiaire d'actionnement est entraîné en rotation en suivant un trajet hélicoïdal, comme un tire-bouchon, pour enfoncer axialement l'axe de support de la cage à ressort, ce qui entraîner axialement le pont électrique jusqu'au contact des têtes des plots électriques, le ressort principal maintenant le pont au fond de l'axe de support. La poignée de manoeuvre continue à tourner jusqu'à la position "ON" de fermeture du coupe-circuit, ce qui se traduit par la poursuite du déplacement axial de l'axe de support de la cage à ressort. Etant donné que le pont électrique est déjà en contact mécanique avec les plots électriques donc arrêté dans son déplacement axial, la descente axiale de la cage à ressort se traduit par une compression axiale du ressort principal qui exerce une compression sur le pont électrique le maintenant en contact avec les plots électriques.The circuit breaker according to the invention comprises a rotary operating handle, a housing with a cover and a base tightly assembled and enclosing an axially movable spring cage, axial springs associated with the cage, and an intermediate actuating member actuated by the operating handle to act axially on the movable spring cage. The base is provided with at least two electrical contact pads. According to the invention, the spring cage comprises a support pin provided with a diametrical opening to receive an electric bridge, and a main spring which acts axially against the electric bridge to press it to the bottom of the diametrical opening of the support axis. When the operating handle is actuated from the "OFF" position of electrical cut-off, the intermediate actuating member is rotated by following a helical path, like a corkscrew, to axially drive the axis of support of the spring cage, which axially drive the electric bridge up to contact with the heads of the electric studs, the main spring holding the bridge at the bottom of the support axis. The operating handle continues to rotate to the "ON" position for closing the circuit breaker, which results in the continued axial movement of the support shaft of the spring cage. Since the electric bridge is already in mechanical contact with the electric studs, therefore stopped in its axial movement, the axial descent of the spring cage results in an axial compression of the main spring which exerts a compression on the electric bridge keeping it in contact with electrical contacts.

De préférence, le pont électrique présente un bossage central pour permettre le centrage d'une extrémité du ressort principal dans la cage à ressort, l'autre extrémité du ressort principal étant centrée axialement par une protubérance centrale dans l'ouverture diamétrale de l'axe de support.Preferably, the electric bridge has a central boss to allow centering of one end of the main spring in the spring cage, the other end of the main spring being axially centered by a central protuberance in the diametrical opening of the axis. of support.

Avantageusement, l'axe de support de la cage à ressort est réalisé en une seule pièce par moulage d'une matière plastique rigide.Advantageously, the support axis of the spring cage is made in one piece by molding a rigid plastic material.

La poignée de manoeuvre présente de préférence une masse volumique inférieure ou égale à 0,8 g/cm³, et est rendue amovible par rapport à l'organe intermédiaire d'actionnement au moins pour les positions angulaires de ce dernier correspondant aux positions 'ON" et "OFF" du coupe-circuit. L'organe intermédiaire d'actionnement est de préférence enfermé dans le boîtier du coupe-circuit.The operating handle preferably has a density less than or equal to 0.8 g / cm³, and is made removable with respect to the intermediate actuating member at least for the angular positions of the latter corresponding to the 'ON' positions. and "OFF" of the circuit breaker. The intermediate actuating member is preferably enclosed in the housing of the circuit breaker.

The inner wall of the cover 2a of the housing 2 is provided with a helical guide ramp 8 for cooperating with the lateral lug 3b of the intermediate member 3.

La cage à ressort 4 comprend un axe de support 9 dont la partie supérieure est cylindrique et coulisse de manière étanche à l'aide d'un joint d'étanchéité torique 10 dans une paroi cylindrique 11 du couvercle 2a du boîtier 2. La partie inférieure de l'axe de support 9 présente une ouverture diamétrale 12 dans laquelle est logé un ressort principal 13 de compression et le pont électrique 5 transversal qui présente un bossage central 5a pour permettre le centrage de l'extrémité inférieure du ressort principal 13, l'extrémité supérieure du ressort principal 13 étant centrée par une protubérance centrale 9a de l'axe de support 9 dans le plafond de l'ouverture diamétrale 12. Le fond de l'ouverture diamétrale 12 est plat sur lequel le pont électrique 5 est au repos plaqué par le ressort principal 13. La partie supérieure de l'axe de support 9 présente un logement cylindrique central 9b qui reçoit le téton inférieur cylindrique 3c de l'organe intermédiaire 3. L'extrémité inférieure de l'axe de support 9 présente une protubérance centrale cylindrique 9c assurant le centrage de la partie supérieure du ressort de rappel 6, l'extrémité inférieure du ressort de rappel 6 étant centrée dans un logement cylindrique de l'embase 2b du boîtier 2.The spring cage 4 comprises a support pin 9, the upper part of which is cylindrical and slides in leaktight manner using an O-ring seal 10 in a cylindrical wall 11 of the cover 2a of the housing 2. The lower part of the support axis 9 has a diametrical opening 12 in which is housed a main compression spring 13 and the transverse electric bridge 5 which has a central boss 5a to allow centering of the lower end of the main spring 13, l ' upper end of the main spring 13 being centered by a central protuberance 9a of the support axis 9 in the ceiling of the diametrical opening 12. The bottom of the diametrical opening 12 is flat on which the electric bridge 5 is at rest pressed by the main spring 13. The upper part of the support pin 9 has a central cylindrical housing 9b which receives the cylindrical lower stud 3c from the intermediate member 3. The lower end of the support axis 9 has a cylindrical central protuberance 9c ensuring the centering of the upper part of the return spring 6, the lower end of the return spring 6 being centered in a cylindrical housing of the base 2b of housing 2.

Les plots électriques de contact 7 présentent une partie filetée à l'extérieur de l'embase 2b du boîtier 2 pour coopérer avec des écrous 14 et rondelles 15 en vue d'assurer le raccordement électrique avec les cosses (non représentées) de câbles électriques non représentés, les câbles électriques pouvant être reliés à une batterie électrique d'alimentation et un circuit électrique pour lequel le coupe-circuit de l'invention est utilisé. Les têtes de contact 7a des plots électriques 7 sont à l'intérieur de l'embase 2b afin d'offrir des surfaces de contact électrique qui coopèrent avec le pont électrique 5.The electrical contact pads 7 have a threaded part outside of the base 2b of the housing 2 to cooperate with nuts 14 and washers 15 in order to ensure the electrical connection with the terminals (not shown) of non-electrical cables. shown, the electric cables can be connected to an electric supply battery and an electric circuit for which the circuit breaker of the invention is used. The contact heads 7a of the electrical pads 7 are inside the base 2b in order to provide electrical contact surfaces which cooperate with the electrical bridge 5.

Le fonctionnement du coupe-circuit de l'invention est relativement simple. En partant de la position "OFF" du coupe-circuit, on positionne la poignée de manoeuvre 1 avec la jupe tubulaire 1b autour de la partie supérieure cylindrique du couvercle 2a et la rainure diamétrale de l'organe d'actionnement 1c en couplage mécanique angulaire, par complémentarité de forme, sur la nervure diamétrale 3a de l'organe intermédiaire d'actionnement 3. On exerce ensuite un effort de rotation sur la partie de manoeuvre 1a de la poignée 1 pour entraîner en rotation l'organe intermédiaire d'actionnement 3 qui effectue simultanément un mouvement de translation axial vers le bas grâce à son ergot latéral 3b qui suit la rampe hélicoïdale 8 sur la paroi intérieure du couvercle 2a. Le téton cylindrique inférieur 3c de l'organe intermédiaire 3 tourne librement dans l'évidement axial 9b tout en appuyant sur le fond de cet évidement 9b situé à la partie supérieure de l'axe de support 9 de la cage à ressort 4, afin de communiquer à l'axe de support 9 le même mouvement de translation axiale vers le bas. Le pont électrique transversal 5 maintenu au fond de l'ouverture diamétrale 12 de l'axe de support par le ressort principal 13 effectue le même mouvement de translation axiale et entre en contact avec les têtes 7a des plots électriques 7. On continue à tourner la poignée de manoeuvre 1 jusqu'à la position "ON" qui est décalée angulairement de 90° par rapport à la position "OFF" dans cet exemple. L'axe de support 9 continue sa course de descente axiale tandis que le pont électrique 5 est arrêté par les têtes 7a des plots électriques 7. Le ressort principal 13 est alors comprimé axialement entre le plafond de l'ouverture diamétrale 12 de l'axe de support 9 qui continue sa descente et le pont électrique 5 immobile. De cette façon, le ressort principal 13 exerce un effort axial sur le pont électrique 5 le maintenant en contact avec les têtes 7a des plots électriques 7. Le courant électrique peut alors circuler d'un plot électrique 7 à l'autre via le pont électrique 5. L'effort de compression exercé par le ressort principal 13 sur le pont électrique 5 permet d'assurer le contact électrique entre le pont 5 et les têtes 7a des plots contre des vibrations mécaniques. Lorsque l'on veut ouvrir le circuit, il suffit de tourner la poignée de manoeuvre 1 dans le sens inverse jusqu'à la position "OFF" du coupe-circuit, le ressort de rappel 6 exerçant un effort sur le fond de la cage à ressort 4 pour la maintenir en position haute. Le pont électrique 5 est séparé des têtes 7a des plots électriques 7 en position "OFF" du coupe-circuit.The operation of the circuit breaker of the invention is relatively simple. Starting from the "OFF" position of the circuit breaker, position the operating handle 1 with the tubular skirt 1b around the cylindrical upper part of the cover 2a and the groove diametral of the actuating member 1c in angular mechanical coupling, by shape complementarity, on the diametral rib 3a of the intermediate actuating member 3. A rotation force is then exerted on the operating part 1a of the handle 1 for rotating the intermediate actuating member 3 which simultaneously performs a downward axial translational movement thanks to its lateral lug 3b which follows the helical ramp 8 on the inner wall of the cover 2a. The lower cylindrical pin 3c of the intermediate member 3 rotates freely in the axial recess 9b while pressing on the bottom of this recess 9b located at the upper part of the support axis 9 of the spring cage 4, in order to communicating to the support axis 9 the same axial downward movement. The transverse electric bridge 5 held at the bottom of the diametrical opening 12 of the support axis by the main spring 13 performs the same movement of axial translation and comes into contact with the heads 7a of the electrical pads 7. The rotation continues operating handle 1 to the "ON" position which is angularly offset by 90 ° relative to the "OFF" position in this example. The support axis 9 continues its axial downward travel while the electric bridge 5 is stopped by the heads 7a of the electric pads 7. The main spring 13 is then compressed axially between the ceiling of the diametrical opening 12 of the axis support 9 which continues its descent and the electric bridge 5 immobile. In this way, the main spring 13 exerts an axial force on the electric bridge 5 keeping it in contact with the heads 7a of the electric pads 7. The electric current can then flow from an electric pad 7 to the other via the electric bridge 5. The compression force exerted by the main spring 13 on the electric bridge 5 ensures electrical contact between the bridge 5 and the heads 7a of the pads against mechanical vibrations. When you want to open the circuit, simply turn the operating handle 1 in the opposite direction to the "OFF" position of the circuit breaker, the return spring 6 exerting a force on the bottom of the cage to spring 4 to keep it in the high position. The electric bridge 5 is separated from the heads 7a of the electric pads 7 in the "OFF" position of the circuit breaker.

De préférence, la poignée de manoeuvre 1 est amovible au moins aussi bien en position "ON' qu'en position "OFF" du coupe-circuit. La surface de l'extrémité supérieure du couvercle 2 peut comporter des indications "ON" et "OFF" qui coopèrent avec la nervure diamétrale 3a de l'organe intermédiaire 3 pour permettre à l'usager de visualiser facilement et rapidement l'état électrique du coupe-circuit lorsque la poignée de manoeuvre 1 est enlevée (figure 3).Preferably, the operating handle 1 is removable at least as well in the "ON" position as in the "OFF" position of the circuit breaker. The surface of the upper end of the cover 2 may include indications "ON" and " OFF "which cooperate with the diametrical rib 3a of the intermediate member 3 to allow the user to easily and quickly visualize the electrical state of the circuit breaker when the operating handle 1 is removed (FIG. 3).

La poignée de manoeuvre rotative 1 est de préférence réalisée en matière synthétique rigide et légère de façon à la rendre insubmersible dans l'eau. Dans le même esprit, la surface extérieure de la poignée 1 peut être revêtue d'un revêtement de couleur vive et/ou phosphorescent pour permettre son repérage facile. De tels critères sont très appréciés lorsque le coupe-circuit est destiné à équiper des bateaux.The rotary operating handle 1 is preferably made of rigid and light synthetic material so as to make it unsinkable in water. In the same spirit, the external surface of the handle 1 can be coated with a coating of bright color and / or phosphorescent to allow its easy identification. Such criteria are highly appreciated when the circuit breaker is intended to equip boats.

La poignée de manoeuvre 1 comporte de préférence une perforation le pour permettre le passage d'un anneau porte-clé. Ainsi, la poignée amovible 1 peut servir de porte-clé à l'usager, ce qui permet de diminuer le risque de perte de clés utiles au fonctionnement du véhicule ou du bateau, surtout lorsque ces clés sont nombreuses.The operating handle 1 preferably comprises a perforation to allow the passage of a key ring. Thus, the removable handle 1 can serve as a key holder for the user, which makes it possible to reduce the risk of losing keys useful for the operation of the vehicle or the boat, especially when these keys are numerous.

Le boîtier 2 et l'axe de support 9 sont de préférence réalisés en matière plastique. Dans l'exemple de réalisation, l'axe de support 9 est en polyamide 6-6 chargé en fibres de verre à 30% en poids.The housing 2 and the support pin 9 are preferably made of plastic. In the embodiment, the support axis 9 is made of polyamide 6-6 loaded with glass fibers at 30% by weight.

Le couvercle 2a et l'embase 2b présentent en commun deux oreilles latérales pourvues chacune d'une perforation 16 permettant le passage d'une vis de fixation non représentée. Un écrou 17 est noyé dans l'embase dans le prolongement de chaque perforation 16 de façon à le rendre imperdable. Cela permet de fixer le coupe-cicrcuit sur un support non représenté dans le cas où l'accès de ces écrous 17 de montage s'avère difficile, voire impossible.The cover 2a and the base 2b have in common two lateral ears each provided with a perforation 16 allowing the passage of a fixing screw not shown. A nut 17 is embedded in the base in the extension of each perforation 16 so as to make it captive. This makes it possible to fix the cutter on a support not shown in the case where the access of these mounting nuts 17 proves difficult, even impossible.
