Il est proposé un dispositif de connexion électrique comprenant un connecteur. Le connecteur comprend une interface de connexion électrique et un organe de fixation amovible d'un câble à l'interface de connexion électrique. Le dispositif de connexion électrique comprend également une enveloppe solidarisée de manière amovible au connecteur. L'enveloppe étant solidarisée de manière amovible au connecteur, le connecteur peut donc être séparé de l'enveloppe. En outre, le connecteur étant fixé de manière amovible au câble, le câble peut donc également être séparé du connecteur. Le dispositif peut donc être aisément démontable.There is provided an electrical connection device comprising a connector. The connector comprises an electrical connection interface and a removable fastener of a cable to the electrical connection interface. The electrical connection device also comprises an envelope secured to the connector removably. The envelope being secured in a removable manner to the connector, the connector can be separated from the envelope. In addition, since the connector is removably attached to the cable, the cable can also be separated from the connector. The device can therefore be easily dismounted.

La figure 1 décrit une vue d'un dispositif 9 de connexion électrique. Selon la figure 1, le dispositif 9 de connexion électrique comprend une enveloppe 10 et un connecteur 20. Le dispositif 9 permet d'alimenter des appareils électriques tels que des pompes de circulation.The figure 1 discloses a view of an electrical connection device 9. According to figure 1 , the electrical connection device 9 comprises an envelope 10 and a connector 20. The device 9 is used to power electrical devices such as circulation pumps.

La figure 2 montre l'enveloppe 10 du dispositif 9 de connexion électrique. L'enveloppe 10 comprend un logement intérieur pour accueillir le connecteur 20. L'enveloppe est ouverte à deux extrémités pour le passage d'un câble 30. Le câble 30 traverse l'enveloppe 10 de part en part. L'extrémité 16 est ouverte de sorte à permettre l'introduction du connecteur dans l'enveloppe 10. A l'extrémité 17 opposée, l'enveloppe 10 comporte un organe de blocage 12, 13 permettant d'immobiliser l'enveloppe 10 le long du câble 30.The figure 2 shows the envelope 10 of the device 9 of electrical connection. The envelope 10 comprises an inner housing to accommodate the connector 20. The envelope is open at two ends for the passage of a cable 30. The cable 30 passes through the envelope 10 from one side. The end 16 is open so as to allow the introduction of the connector into the casing 10. At the opposite end 17, the casing 10 comprises a locking member 12, 13 for immobilizing the casing 10 along cable 30.

L'enveloppe 10 comprend également un orifice 14. L'orifice 14 se trouve sur une paroi de l'enveloppe 10. L'orifice peut être à proximité de l'extrémité 16 de l'enveloppe 10.The envelope 10 also comprises an orifice 14. The orifice 14 is on a wall of the envelope 10. The orifice may be close to the end 16 of the envelope 10.

La figure 2 montre aussi un organe de blocage 12, 13 de l'enveloppe 10 au câble 30. L'organe de blocage 12, 13 est par exemple à l'extrémité 17 de l'enveloppe 10. Ainsi, une fois le connecteur 20 introduit dans l'enveloppe 10, l'organe de blocage 12, 13 permet de bloquer en translation l'enveloppe 10 le long du câble par rapport au connecteur 20.The figure 2 also shows a blocking member 12, 13 of the casing 10 to the cable 30. The locking member 12, 13 is for example at the end 17 of the casing 10. Thus, once the connector 20 introduced into the casing 10, the blocking member 12, 13 makes it possible to lock the casing 10 in translation along the cable with respect to the connector 20.

L'organe de blocage 12, 13 peut par exemple comprendre des pattes 12 articulées sur l'enveloppe 10 et une bague 13. Les pattes 12 sont sollicitées élastiquement par la bague 13 vissée sur les pattes 12. Les pattes 12 sont articulées en porte-à-faux à l'extrémité 17 de l'enveloppe 10. Les pattes 12 s'étendent le long et autour du câble. Les pattes 12 comportent un pas de vis sur lequel la bague 13 peut être vissée. Le vissage de la bague 13 sur le pas de vis permet de resserrer les pattes 12 les unes contre les autres et contre le câble afin d'exercer une pression croissante sur le câble 30. L'organe de blocage est réversible puisqu'il suffit de dévisser la bague 13 pour permettre de libérer l'emprise de l'enveloppe 10 sur le câble 30 afin de démonter l'enveloppe 10.The locking member 12, 13 may for example comprise tabs 12 articulated on the casing 10 and a ring 13. The tabs 12 are resiliently biased by the ring 13 screwed onto the tabs 12. The tabs 12 are hinged in at the end 17 of the envelope 10. The tabs 12 extend along and around the cable. The tabs 12 comprise a screw thread on which the ring 13 can be screwed. The screwing of the ring 13 on the screw thread makes it possible to tighten the tabs 12 against each other and against the cable in order to exert increasing pressure on the cable 30. The locking member is reversible since it is sufficient to unscrewing the ring 13 to make it possible to release the grip of the envelope 10 on the cable 30 in order to disassemble the envelope 10.

De retour sur la figure 1, le connecteur 20 permet de relier électriquement un appareil à un réseau d'alimentation électrique. Le connecteur 20 à des dimensions adaptées à pénétrer dans l'enveloppe 10 par l'extrémité 16. Le connecteur 20 comporte une interface de connexion électrique et un organe de fixation amovible d'un câble à l'interface de connexion électrique. L'interface de connexion est par exemple établie par l'action d'un contact ressort qui vient plaquer le brin dénudé du câble 30 sur une autre pièce conductrice. L'organe de fixation est par exemple un pion mobile à l'intérieur du connecteur 20 pour fixer les brins de câbles contre chacune des pistes conductrices. L'organe de fixation peut être sollicité par un ressort. Le ressort permet à l'organe de fixation de contraindre le câble contre l'interface de connexion électrique. De préférence, le ressort est maintenu comprimé pour maintenir la pression de l'organe de fixation contre le câble. Ainsi la réserve de pression assurée par la compression du ressort permet de compenser les éventuels fluages des matériaux conducteurs. La qualité de la conduction est ainsi préservée au cours du temps.Back on the figure 1 , the connector 20 makes it possible to electrically connect an apparatus to a power supply network. The connector 20 has dimensions adapted to penetrate into the casing 10 by the end 16. The connector 20 comprises an electrical connection interface and a removable fastener of a cable to the electrical connection interface. The connection interface is for example established by the action of a spring contact which comes to press the bare strand of the cable 30 on another conductive part. The fixing member is for example a movable pin inside the connector 20 for fixing the cable strands against each of the conductive tracks. The fastener may be biased by a spring. The spring allows the fastener to constrain the cable against the electrical connection interface. Preferably, the spring is held compressed to maintain the pressure of the fastener against the cable. Thus, the pressure reserve provided by the compression of the spring makes it possible to compensate for any fluctuations in the conductive materials. The quality of the conduction is thus preserved over time.

Le connecteur 20 comprend une ouverture 28 d'insertion du câble. L'ouverture 28 permet d'introduire le câble 30 dans le connecteur 20 et de mettre le câble 30 en contact électrique avec l'interface de connexion électrique du connecteur 20. Selon le mode de réalisation de la figure 1, l'ouverture 28 d'insertion est sur une face latérale du connecteur 20. L'ouverture 28 est ouverte dans une direction transversale à la direction du câble 30 une fois le connecteur 20 assemblé à l'enveloppe 10. Il est possible d'orienter l'ouverture 28 dans une direction qui forme un angle avec l'axe d'insertion du câble 30 dans le connecteur pour accepter ainsi des variations de longueur des brins dénudés du câble 30.The connector 20 comprises an opening 28 for insertion of the cable. The opening 28 makes it possible to introduce the cable 30 into the connector 20 and to put the cable 30 in electrical contact with the electrical connection interface of the connector 20. According to the embodiment of FIG. figure 1 , the insertion opening 28 is on a lateral face of the connector 20. The opening 28 is open in a direction transverse to the direction of the cable 30 once the connector 20 has been assembled to the envelope 10. It is possible to orienting the opening 28 in a direction which forms an angle with the insertion axis of the cable 30 in the connector to thereby accept variations in the length of the strands of the strand 30.

Le connecteur 20 comporte en outre un actionneur 22 tel que représenté sur la figure 5. L'actionneur 22 permet d'actionner l'organe de fixation pour permettre d'introduire le brin dénudé du câble 30 dans l'interface de connexion électrique ou inversement, pour permettre de libérer le câble. A titre d'exemple, l'actionneur 22 actionne l'organe de fixation sous forme de came à l'encontre du ressort. L'actionneur 22 peut être un bouton ou, selon l'exemple de la figure 1, un ou plusieurs leviers en saillie du connecteur 20. Les leviers sont adaptés pour être actionnés facilement et sans outils. A titre d'exemple l'actionneur 22 de l'organe de fixation peut être actionné par un doigt 40. L'absence de nécessité d'outil pour actionner l'actionneur 22 permet d'introduire ou retirer aisément le câble. De plus l'absence de nécessité d'utilisation d'outils assure une plus grande sécurité à l'opérateur en prévenant les accidents éventuels avec ceux-ci.The connector 20 further comprises an actuator 22 as represented on the figure 5 . The actuator 22 actuates the fastener to allow the bare strand of the cable 30 to be inserted into the electrical connection interface or vice versa, to allow the cable to be released. For example, the actuator 22 actuates the fixing member in the form of a cam against the spring. The actuator 22 may be a button or, according to the example of the figure 1 , one or more levers protruding from the connector 20. The levers are adapted to be operated easily and without tools. For example the actuator 22 of the body of fixation can be operated by a finger 40. The lack of tool need to actuate the actuator 22 makes it easy to introduce or remove the cable. In addition, the lack of need for the use of tools ensures greater safety for the operator by preventing any accidents with them.

Lorsqu'il n'est pas actionné, l'actionneur 22 est dans une position haute, dans le prolongement du connecteur 20. La position haute permet au connecteur 20 d'être introduit dans l'enveloppe 10 au travers de l'extrémité 16. Une fois que le connecteur 20 a été introduit dans l'enveloppe 10 avec l'actionneur 22 dans la position haute, l'actionneur 22 est masqué par l'enveloppe. L'actionneur 22 est non seulement inaccessible mais, de plus, ne peut pas être actionné de manière intempestive, empêchant ainsi la libération du câble. L'actionneur 22 est retenu par les parois de l'enveloppe 10.When not actuated, the actuator 22 is in a high position, in the extension of the connector 20. The high position allows the connector 20 to be introduced into the envelope 10 through the end 16. Once the connector 20 has been inserted into the casing 10 with the actuator 22 in the high position, the actuator 22 is masked by the casing. The actuator 22 is not only inaccessible but, moreover, can not be actuated inadvertently, thus preventing the release of the cable. The actuator 22 is retained by the walls of the casing 10.

Le connecteur 20 comprend en outre une sortie 26 pour brancher le dispositif 9 à un appareil électrique.The connector 20 further comprises an outlet 26 for connecting the device 9 to an electrical appliance.

Le connecteur 20 comprend également un organe de solidarisation 24 à l'enveloppe 10. L'organe de solidarisation 24 est par exemple un croc qui coopère avec l'enveloppe 10 pour immobiliser le connecteur 20 à l'enveloppe 10. L'organe de solidarisation 24 peut être un croc élastique 24 du type un clip, c'est-à-dire une fixation par pince formant ressort. Le croc 24 est en saillie du connecteur 20 pour coopérer avec l'enveloppe 10. Le croc 24 est adapté à solidariser automatiquement le connecteur 20 à l'enveloppe 10 lorsque le connecteur 20 est introduit dans l'enveloppe 10. En particulier, le croc 24 est placé de manière à être en vis-à-vis de l'orifice 14 lorsque le connecteur 20 est introduit dans l'enveloppe 10. Le croc 24 coopère alors avec le pourtour de l'orifice 14 lorsque le connecteur 20 est introduit dans l'enveloppe 10. L'assemblage du connecteur 20 à l'enveloppe est donc simple et rapide.The connector 20 also comprises a securing member 24 to the casing 10. The securing member 24 is for example a hook that cooperates with the casing 10 to immobilize the connector 20 to the casing 10. The fastening member 24 can be an elastic hook 24 of the type a clip, that is to say a clamping clip forming spring. The hook 24 protrudes from the connector 20 to cooperate with the casing 10. The hook 24 is adapted to automatically secure the connector 20 to the casing 10 when the connector 20 is inserted into the casing 10. In particular, the hook 24 is placed so as to face the orifice 14 when the connector 20 is inserted into the envelope 10. The hook 24 then co-operates with the periphery of the orifice 14 when the connector 20 is introduced into the envelope 10. The assembly of the connector 20 to the envelope is thus simple and fast.

Lorsque l'enveloppe 10 et le connecteur 20 sont assemblés ensemble par le croc 24, l'ensemble forme alors un boîtier fermé. Le fait que le dispositif 9 de connexion électrique forme un boîtier fermé permet de ne pas laisser libre accès aux éléments de connexion électrique. De cette manière le dispositif 9 de connexion électrique est sécurisé.When the casing 10 and the connector 20 are assembled together by the hook 24, the assembly then forms a closed casing. The fact that the electrical connection device 9 forms a closed housing makes it possible not to allow free access to the electrical connection elements. In this way the device 9 of electrical connection is secure.

Le dispositif 9 permet la connexion électrique à tout type de câbles 30. En particulier, la connexion peut aussi bien être effectuée avec des câbles 30 neufs que des câbles 30 déjà installés. Ceci permet d'adapter le dispositif 9 sur des installations existantes. La maintenance de la connexion électrique d'appareils en cours d'utilisation est également facilitée.The device 9 allows the electrical connection to any type of cable 30. In particular, the connection can be made with new cables 30 as well as cables 30 already installed. This makes it possible to adapt the device 9 to existing installations. Maintenance of the electrical connection of devices in use is also facilitated.

A titre d'exemple, le montage et le démontage du câble au dispositif 9 de connexion électrique peut être réalisé de la manière suivante et en liaison avec la figure 3.By way of example, the assembly and disassembly of the cable to the electrical connection device 9 can be carried out in the following manner and in connection with the figure 3 .

Le connecteur 20 est hors de l'enveloppe 10 et l'actionneur 22 est en position haute. La bague 13 et l'enveloppe 10 sont tout d'abord introduits le long du câble. Puis l'extrémité dénudée du câble est présentée pour l'insertion dans l'ouverture 28 du connecteur 20 suivant la flèche 60. L'organe de fixation est actionné par l'actionneur 22 pour permettre d'insérer le câble dans l'interface de connexion électrique. La pression suivant la flèche 64 par le doigt 40 sur l'actionneur 22 libère l'accès à l'interface de connexion électrique. L'actionneur 22 sollicite l'organe de fixation qui comprime le ressort. Une fois le câble en position dans l'interface de connexion électrique, l'actionneur 22 est relâché ce qui tend à redresser l'actionneur 22 vers sa position haute par le biais de l'organe de fixation et la détente du ressort. Eventuellement, l'actionneur 22 est poussé vers sa position haute pour permettre l'introduction plus aisée du connecteur 20 dans l'enveloppe 10. L'organe de fixation maintient le câble en position dans l'interface de connexion électrique. Le câble 30 est alors pivoté autour de son extrémité immobilisée dans l'interface de connexion électrique. Ce pivotement s'effectue selon la direction de la flèche 62. Le pivotement met le câble dans le prolongement du connecteur à l'extrémité opposé à celle de la sortie 26 (comme représenté sur la figure 1). L'enveloppe 10 est alors descendue le long du câble puis le connecteur 20 est introduit dans l'enveloppe 10. L'enveloppe 10 se solidarise au connecteur 20 par l'intermédiaire de l'organe de solidarisation 24. La solidarisation se fait automatiquement par déformation élastique de l'organe de solidarisation 24 à l'encontre du pourtour de l'orifice 14. L'introduction du connecteur 20 dans l'enveloppe 10 permet de coincer le câble entre le connecteur 20 et l'enveloppe 10. Le câble 30 est alors maintenu selon une direction transversale à la direction d'insertion du câble dans l'interface de connexion électrique. Ceci permet de réduire le risque d'arrachement du câble hors du dispositif 9. Enfin, le cas échéant, l'organe de blocage de l'enveloppe 10 au câble 30 est actionné. Pour cela, la bague 13 est descendue le long du câble et est vissée sur les pattes 12. Ceci permet d'immobiliser le câble à l'enveloppe de sorte à réduire encore les risques d'arrachement du câble. Le raccordement électrique sécurisé entre un câble et le dispositif 9 de connexion électrique s'effectue sans aucun outil.The connector 20 is out of the casing 10 and the actuator 22 is in the up position. The ring 13 and the envelope 10 are first introduced along the cable. Then the bare end of the cable is presented for insertion into the opening 28 of the connector 20 along the arrow 60. The fastener is actuated by the actuator 22 to allow insertion of the cable into the interface of electrical connection. The pressure along the arrow 64 by the finger 40 on the actuator 22 releases access to the electrical connection interface. The actuator 22 urges the fastener which compresses the spring. Once the cable is in position in the electrical connection interface, the actuator 22 is released which tends to straighten the actuator 22 to its upper position through the fastener and the expansion of the spring. Optionally, the actuator 22 is pushed to its upper position to allow easier introduction of the connector 20 in the casing 10. The fixing member holds the cable in position in the electrical connection interface. The cable 30 is then pivoted around its immobilized end in the electrical connection interface. This pivoting is effected in the direction of the arrow 62. The pivoting puts the cable in the extension of the connector at the opposite end to that of the outlet 26 (as shown in FIG. figure 1 ). The casing 10 is then lowered along the cable and the connector 20 is inserted into the casing 10. The casing 10 is secured to the connector 20 via the securing member 24. The joining is done automatically by elastic deformation of the securing member 24 against the periphery of the orifice 14. The introduction of the connector 20 in the casing 10 makes it possible to wedge the cable between the connector 20 and the envelope 10. The cable 30 is then maintained in a direction transverse to the insertion direction of the cable in the electrical connection interface. This reduces the risk of pulling the cable out of the device 9. Finally, if necessary, the locking member of the casing 10 to the cable 30 is actuated. For this, the ring 13 is lowered along the cable and is screwed on the legs 12. This allows to immobilize the cable to the envelope so as to further reduce the risk of tearing of the cable. The secure electrical connection between a cable and the electrical connection device 9 is performed without any tools.

La figure 4 est un schéma d'un organe 24 de solidarisation. La solidarisation est assurée par la collaboration entre l'organe de solidarisation 24 du connecteur 20 et le pourtour de la périphérie de l'orifice 14 de l'enveloppe. L'organe 24 de solidarisation par exemple sous forme de croc élastique se fixe par clipsage au pourtour de l'orifice 14. Le clipsage est une opération simple et ne nécessitant pas l'utilisation d'outils pour la solidarisation. Lors de l'introduction du connecteur 20 dans l'enveloppe 10, le croc 24 s'efface puis reprend automatiquement sa position d'équilibre lorsque le croc est en regard de l'orifice 14. La position d'équilibre est celle dans laquelle l'extrémité du croc 24 s'érige dans l'orifice 14. Cette position du croc 24 empêche les mouvements relatifs du connecteur 20 par rapport à l'enveloppe 10. En particulier les translations de l'enveloppe 10 par rapport au connecteur 20 le long du câble 30 sont empêchées. Un tel organe de solidarisation 24 présente l'avantage de ne pas nécessiter l'utilisation d'outil pour la fermeture. La manoeuvre est donc simple, rapide et prévient les risques de blessure par utilisation des outils. En outre, l'organe 24, de par l'absence de nécessité de l'utilisation d'outil prévient les risques de détérioration des attaches telles que par exemples les pas de vis détérioré. De telle détérioration rendent les opérations plus difficile et moins efficace.The figure 4 is a diagram of a fastening member 24. The securing is ensured by the collaboration between the fastening member 24 of the connector 20 and the periphery of the periphery of the orifice 14 of the envelope. The fastening member 24, for example in the form of an elastic hook, is fixed by clipping around the periphery of the orifice 14. Clipping is a simple operation and does not require the use of tools for solidarity. When the connector 20 is inserted into the envelope 10, the hook 24 disappears and then automatically resumes its equilibrium position when the hook is facing the orifice 14. The equilibrium position is that in which the end of the hook 24 is raised in the orifice 14. This position of the hook 24 prevents the relative movements of the connector 20 with respect to the shell 10. In particular the translations of the shell 10 with respect to the connector 20 along cable 30 are prevented. Such a securing member 24 has the advantage of not requiring the use of a tool for closing. The maneuver is simple, fast and prevents the risk of injury by using the tools. In addition, the member 24, due to the absence of need for the use of tools prevents the risk of deterioration of the fasteners such as for example deteriorated screw pitches. Such deterioration makes operations more difficult and less effective.

La solidarisation entre l'enveloppe 10 et le connecteur 20 est amovible. Le caractère amovible de la solidarisation assure la possibilité d'opération de maintenance. En particulier les organes de fixation, de blocage 12, 13 et de solidarisation 24 peuvent être manoeuvrés en sens inverse à ce qui a été décrit pour pourvoir libérer le câble.The connection between the envelope 10 and the connector 20 is removable. The removable nature of the fastening ensures the possibility of maintenance operation. In particular, the fastening, locking 12, 13 and securing members 24 can be maneuvered in the opposite direction to what has been described to allow the cable to be released.

Pour cela, l'organe de blocage de l'enveloppe 10 au câble 30 est libéré en premier lieu. La bague 13 est dévissée, libérant le câble de l'emprise des pattes 12. Selon la figure 4, un outil 50 (par exemple un tournevis) est ensuite introduit à travers l'orifice 14 pour retirer l'organe de solidarisation 24 de l'orifice 14. Lorsque l'organe 24 n'est plus en regard du pourtour de l'orifice 14, l'enveloppe 10 peut être dégagée du connecteur 20 par translation le long du câble 30. Le câble 30 est alors basculé pour être dans le prolongement de l'ouverture 28 comme représenté sur la figure 3. Une pression sur l'actionneur 22 selon la flèche 64 sur la figure 3 permet de libérer l'organe de fixation du câble 30 dans l'interface de connexion électrique. Le câble 30 n'étant plus retenu peut être retiré du connecteur 20.For this, the locking member of the casing 10 to the cable 30 is released first. The ring 13 is unscrewed, releasing the cable from the grip of the legs 12. According to the figure 4 a tool 50 (for example a screwdriver) is then introduced through the orifice 14 to remove the securing member 24 from the orifice 14. When the member 24 is no longer facing the periphery of the orifice 14, the casing 10 can be disengaged from the connector 20 by translation along the cable 30. The cable 30 is then tilted to be in the extension of the opening 28 as shown in FIG. figure 3 . Pressure on the actuator 22 according to the arrow 64 on the figure 3 allows to release the fixing member of the cable 30 in the electrical connection interface. The cable 30 no longer retained can be removed from the connector 20.

De préférence, l'enveloppe 10 est adaptée à être désolidarisée du connecteur 20 par action de l'organe de solidarisation uniquement par un outil. Ceci évite d'actionner intempestivement l'organe 24. L'orifice 14 est d'une taille inférieure à un doigt pour éviter un actionnement involontaire (ou volontaire) de l'organe 24.Preferably, the casing 10 is adapted to be disengaged from the connector 20 by the action of the fastening member only by a tool. This avoids unwanted actuation of the member 24. The orifice 14 is of a size smaller than a finger to avoid involuntary (or deliberate) actuation of the member 24.
