Abstract
Description
Dispositif et procédé de connexion d'un moteur électrique Device and method for connecting an electric motor
L'invention concerne un dispositif de connexion d'un moteur électrique, en particulier d'un moteur d'essuie-glace de véhicule. The invention relates to a device for connecting an electric motor, in particular a vehicle wiper motor.
Les moteurs d'essuie-glace de véhicule automobile comportent généralement une enceinte ou un boîtier dans lequel sont placés des composants. Ces composants comportent, par exemple, un bobinage, des aimants, un collecteur et des charbons reliés à un circuit d'alimentation qui peut être filaire et/ou comprendre une carte électronique. Motor vehicle wiper motors generally include an enclosure or housing in which components are placed. These components include, for example, a winding, magnets, a collector and coals connected to a supply circuit which can be wired and / or comprise an electronic card.
Ce circuit d'alimentation doit être relié au circuit électrique du véhicule, appelé ici circuit extérieur, afin d'être alimenté en puissance et piloté. This power circuit must be connected to the vehicle's electrical circuit, called here external circuit, in order to be powered and controlled.
L'élément de liaison entre le circuit d'alimentation du moteur et le circuit extérieur est appelé connecteur. Il est connu de réaliser les connecteurs essentiellement sous deux formes différentes : les connecteurs intégrés, et les connecteurs rapportés. The connecting element between the motor supply circuit and the external circuit is called the connector. It is known to make the connectors essentially in two different forms: integrated connectors, and connectors reported.
Les connecteurs intégrés sont partie intégrante de l'enceinte du moteur. Ces connecteurs intégrés sont généralement moulés avec un couvercle plastique de l'enceinte. Il en résulte que ces connecteurs sont très variés en forme, ce qui soulève des problèmes d'interchangeabilité. The integrated connectors are an integral part of the motor enclosure. These integrated connectors are usually molded with a plastic cover of the enclosure. As a result, these connectors are very varied in shape, which raises problems of interchangeability.
Les connecteurs rapportés se présentent sous forme d'une pièce supplémentaire qui est insérée dans une ouverture traversant l'enceinte du moteur, avec deux extrémités de connexion, une côté composants du moteur, une côté circuit extérieur. En changeant le ou les élément(s) de connexion, il est possible d'adapter de nombreux moteurs sur de nombreux circuits. En revanche, ces connecteurs rapportés posent des problèmes d'étanchéité puisqu'ils sont insérés dans une ouverture qui représente une brèche dans l'enceinte. La connexion se faisant au niveau du circuit électrique, les infiltrations ont lieu à cet endroit sensible du moteur, ce qui conduit à une dégradation plus ou moins rapide de ce dernier. The reported connectors are in the form of an additional piece which is inserted into an opening through the motor housing, with two connecting ends, one component side of the motor, one outer circuit side. By changing the element (s) of connection, it is possible to adapt many engines on many circuits. However, these reported connectors pose sealing problems since they are inserted into an opening which represents a breach in the enclosure. Since the connection is made at the level of the electrical circuit, the infiltrations take place at this sensitive point of the motor, which leads to a more or less rapid degradation of the latter.
Pour pallier ces défauts d'étanchéité, il est connu d'utiliser des joints qui sont souvent difficiles à mettre en place et sont des points faibles lorsque le moteur vieillit. To overcome these leaks, it is known to use joints that are often difficult to implement and are weak points when the engine ages.
L'invention vise à répondre au moins partiellement aux problèmes précédemment mentionnés. L'invention porte ainsi sur un dispositif de connexion de moteur électrique, destiné à connecter un circuit intérieur du moteur électrique à un circuit extérieur, et comprenant un corps en matière isolante dans lequel au moins un conducteur électrique est partiellement surmoulé. Un appendice prolonge ledit corps et présente une face de sortie du conducteur électrique. Et le au moins un conducteur électrique présente en saillie de la face de sortie de l'appendice une portion coudée pour former un élément de connexion électrique qui s'étend sensiblement parallèlement à la face de sortie. The invention aims to at least partially meet the previously mentioned problems. The invention thus relates to an electric motor connection device for connecting an internal circuit of the electric motor to a external circuit, and comprising a body of insulating material in which at least one electrical conductor is partially overmolded. An appendage extends said body and has an output face of the electrical conductor. And the at least one electrical conductor has a protruding portion of the output face of the appendage a bent portion to form an electrical connection element which extends substantially parallel to the exit face.
L'invention permet d'obtenir un dispositif de connexion qui peut être adapté aux différents véhicules et configurations de moteurs électrique avec boîtier et couvercle. La configuration du dispositif de connexion permet notamment de proposer un élément de connexion électrique facilitant la connexion au circuit intérieur du moteur, sans pour autant avoir un élément de connexion rendu fragile par une position en saillie de l'appendice trop exposée. The invention provides a connection device that can be adapted to different vehicles and configurations of electric motors with housing and cover. The configuration of the connection device allows in particular to provide an electrical connection element facilitating connection to the internal circuit of the engine, without having a connection element made fragile by a protruding position of the appendix too exposed.
Le dispositif de connexion peut en outre comporter une ou plusieurs des caractéristiques suivantes, prises seules ou en combinaison : The connection device may further comprise one or more of the following features, taken alone or in combination:
- le conducteur électrique comporte deux portions d'extrémité sensiblement parallèles l'une par rapport à l'autre et séparées par une portion centrale sensiblement perpendiculaire aux deux portions d'extrémité, de manière à présenter une forme générale en marche d'escalier ; - The electrical conductor has two end portions substantially parallel to each other and separated by a central portion substantially perpendicular to the two end portions, so as to have a general shape staircase;
la portion centrale du conducteur électrique émerge au niveau de la face de sortie de l'appendice ; the central portion of the electrical conductor emerges at the outlet face of the appendix;
l'une des portions d'extrémité forme ledit élément de connexion électrique ; one of the end portions forms said electrical connection member;
le conducteur électrique est une lame métallique, notamment du cuivre ; l'élément de connexion électrique est monobloc avec le au moins un conducteur électrique disposé dans le corps et l'appendice ; the electrical conductor is a metal blade, in particular copper; the electrical connection element is integral with the at least one electrical conductor disposed in the body and the appendix;
l'élément de connexion électrique est un élément rapporté à l'extrémité libre de la portion coudée. the electrical connection element is an element attached to the free end of the bent portion.
L'invention concerne également un ensemble de connexion d'un circuit intérieur d'un moteur électrique à un circuit extérieur, comportant un dispositif de connexion formé d'un corps isolant et d'un appendice et dans lequel au moins un conducteur électrique est partiellement surmoulé, ledit appendice étant configuré pour déboucher dans un boîtier du moteur électrique au travers d'une ouverture agencée dans un couvercle apte à refermer ledit boîtier, l'appendice et ladite ouverture étant de forme complémentaire. The invention also relates to a connection assembly of an internal circuit of an electric motor to an external circuit, comprising a connection device formed of an insulating body and an appendix and in which at least one conductor electrical is partially overmolded, said appendix being configured to open into an electric motor housing through an opening arranged in a cover adapted to close said housing, the appendix and said opening being of complementary shape.
L'invention permet ainsi d'obtenir un ensemble formé d'un dispositif de connexion tel que précédemment décrit et d'un couvercle de fermeture d'un boîtier de moteur électrique, le couvercle associé de cet ensemble pouvant être standardisé dès lors qu'il présente une ouverture de forme complémentaire à celle de l'appendice. La jonction entre le dispositif de connexion et le couvercle pour former l'ensemble peut ultérieurement être soudée pour assurer une étanchéité supérieure à celle des connecteurs rapportés usuels, notamment par soudage laser ou à ultra-sons. The invention thus makes it possible to obtain an assembly formed of a connection device as previously described and of a closure cover of an electric motor case, the associated cover of this assembly being able to be standardized as soon as it has an opening of complementary shape to that of the appendix. The junction between the connection device and the cover to form the assembly can subsequently be welded to provide a seal greater than that of conventional connectors reported, including laser or ultrasonic welding.
On pourra prévoir que cet ensemble de connexion présente l'une des caractéristiques suivantes, prises seules ou en combinaison les unes des autres : It can be provided that this connection assembly has one of the following characteristics, taken alone or in combination with each other:

- l'appendice comporte une portion cylindrique et l'ouverture présente une forme circulaire ; - The appendix has a cylindrical portion and the opening has a circular shape;
- l'ouverture est localisée dans un bord latéral du couvercle, au moins débouchant sur une face interne du couvercle tournée vers l'intérieur du boîtier, ou bien elle traverse le couvercle depuis une face externe pour déboucher sur une face interne tournée vers l'intérieur du boîtier ; - The opening is located in a side edge of the lid, at least opening on an inner face of the lid facing the interior of the housing, or it passes through the lid from an outer face to open on an inner face facing the inside the case;
- l'appendice et l'ouverture comportent des moyens de coopération de forme par serrage ou par clipsage. - The appendix and the opening comprise form co-operating means by clamping or clipping.
On peut prévoir que le couvercle présente une face interne configurée pour être tournée vers l'intérieur du boîtier et que l'appendice est agencé à travers l'ouverture de sorte que l'appendice présente une face de sortie du conducteur électrique qui est sensiblement parallèle à ladite face interne. It can be provided that the cover has an internal face configured to be turned towards the inside of the housing and that the appendage is arranged through the opening so that the appendix has an exit face of the electrical conductor which is substantially parallel. to said inner face.
Il est notamment avantageux que la face de sortie affleure la face interne du couvercle. In particular, it is advantageous if the outlet face is flush with the internal face of the lid.
Tel que précédemment décrit, le au moins un conducteur électrique peut présenter en saillie de ladite face de sortie de l'appendice une portion coudée pour former un élément de connexion électrique qui s'étend sensiblement parallèlement à ladite face interne du couvercle. Cet élément de connexion électrique est adapté pour être connecté au circuit intérieur du moteur électrique. As previously described, the at least one electrical conductor may have, projecting from said exit face of the appendage, a bent portion for forming an electrical connection element which extends substantially parallel to said inner face of the cover. This electrical connection element is adapted to be connected to the internal circuit of the electric motor.
Selon une caractéristique de l'invention, l'ensemble de connexion comporte en outre un enrobage isolant recouvrant l'élément de connexion électrique. L'enrobage peut ainsi faire office de moyen intermédiaire de fixation de l'élément de connexion électrique sur la face interne du couvercle. Et cet enrobage peut être collé et/ou soudé et/ou clipsé et/ou vissé audit couvercle. According to a characteristic of the invention, the connection assembly further comprises an insulating coating covering the electrical connection element.

And this coating can be glued and / or welded and / or clipped and / or screwed to said cover.
Le dispositif de connexion peut comporter un second appendice situé du côté circuit extérieur et formant une prise mâle pour la connexion au circuit extérieur. The connection device may comprise a second appendix located on the external circuit side and forming a plug for the connection to the external circuit.

L'invention concerne un dispositif de connexion d'un moteur électrique à un circuit extérieur tel que le circuit d'alimentation dans un véhicule, en particulier pour un moteur électrique d'essuie-glace de véhicule. The invention relates to a device for connecting an electric motor to an external circuit such as the supply circuit in a vehicle, in particular for a vehicle wiper electric motor.
La figure 1 montre de façon schématique un moteur 1 raccordé à un circuit extérieur 3, par exemple le circuit électrique du véhicule. Le moteur 1 comporte un circuit intérieur 5, regroupant différents éléments intérieurs qui requièrent une alimentation électrique. FIG. 1 schematically shows a motor 1 connected to an external circuit 3, for example the electric circuit of the vehicle. The motor 1 comprises an internal circuit 5, grouping different interior elements that require a power supply.
Les éléments intérieurs au moteur 1 sont ici : un rotor 7, un stator 9, un bobinage 11, un collecteur 13 et des contacts flottants 15 parfois appelés charbons ou balais. The internal elements of the motor 1 are here: a rotor 7, a stator 9, a coil 11, a collector 13 and floating contacts 15 sometimes called coals or brushes.
Ces éléments de circuit intérieur 5 sont inclus dans un boîtier 19 que ferme un couvercle 21. Ce boîtier 19 fermé par le couvercle 21 forme un récipient qui isole les éléments du circuit intérieur 5 des agressions extérieures (humidité, poussière...). These inner circuit elements 5 are included in a housing 19 that closes a lid 21. This housing 19 closed by the cover 21 forms a container which isolates the elements of the inner circuit 5 external aggressions (moisture, dust ...).
La figure 2 montre plus en détails le moteur 1, en particulier son boîtier 19 et le couvercle 21. FIG. 2 shows in more detail the motor 1, in particular its housing 19 and the cover 21.
Comme représenté sur la figure 2, le couvercle 21 présente une face interne 22 et une face externe 24 opposée l'une par rapport à l'autre, ladite face interne 22 étant tournée vers l'intérieur du boîtier lorsque le couvercle et le boîtier sont assemblés. Le couvercle présente en outre une ouverture 23, de type fente, débouchant vers l'intérieur du boîtier 19 lorsque le couvercle est rapporté sur le boîtier, de manière à donner accès au circuit intérieur 5. Dans ce mode de réalisation particulier, l'ouverture 23 est située sur le bord latéral plein du couvercle 21, c'est-à-dire qu'elle s'étend radial ement dans l'épaisseur du couvercle depuis le bord périphérique du couvercle. L'ouverture 23 s'étend de manière à déboucher sur la face interne 22 du couvercle 21. Ladite ouverture présente ici une forme parallélépipédique. As shown in FIG. 2, the cover 21 has an inner face 22 and an opposite outer face 24 with respect to the other, said inner face 22 being turned towards the inside of the housing when the cover and the housing are assembled. The cover also has a slot-like aperture 23 opening towards the inside of the casing 19 when the cover is attached to the casing so as to give access to the internal circuit 5. In this particular embodiment, the opening 23 is located on the solid side edge of the cover 21, i.e. it extends radially in the thickness of the cover from the peripheral edge of the cover. The opening 23 extends to open on the inner face 22 of the cover 21. Said opening here has a parallelepiped shape.
La figure 3 montre un dispositif de connexion 25 selon l'invention, destiné à coopérer avec le moteur 1 tel que représenté en figure 2. Ledit dispositif de connexion 5 25 comporte un corps 27, prolongé par un appendice 29. L'appendice 29 est de forme complémentaire correspondante à l'ouverture 23 réalisée dans le couvercle 21. Le corps 27 et l'appendice 29 sont réalisés dans une matière isolante telle qu'un thermoplastique. FIG. 3 shows a connection device 25 according to the invention, intended to cooperate with the motor 1 as represented in FIG. 2. Said connecting device 5 comprises a body 27, extended by an appendix 29. Appendix 29 is of complementary shape corresponding to the opening 23 made in the cover 21. The body 27 and the appendix 29 are made of an insulating material such as a thermoplastic.
L'appendice 29 est agencé dans le prolongement du corps de sorte qu'une face de sortie 30 est disposée sensiblement dans le plan défini par la face interne 22 du Appendix 29 is arranged in the extension of the body so that an exit face 30 is disposed substantially in the plane defined by the inner face 22 of the
10 couvercle. Avantageusement, la face de sortie 30 de l'appendice affleure cette face interne 22. L'appendice 29 s'étend dans le prolongement du corps 27 selon une direction d'allongement longitudinal du dispositif de connexion, et la face de sortie s'étend sensiblement dans un plan parallèle à cette direction d'allongement. 10 cover. Advantageously, the outlet face 30 of the appendage is flush with this inner face 22. The appendage 29 extends in the extension of the body 27 in a direction of longitudinal elongation of the connecting device, and the exit face extends substantially in a plane parallel to this direction of elongation.
Le corps 27 et l'appendice 29 du dispositif de connexion 25 sont traversés par au The body 27 and the appendix 29 of the connection device 25 are traversed by at
15 moins un conducteur électrique, ici formé par une lame de connexion 31, qui comporte deux portions d'extrémité sensiblement parallèles l'une par rapport à l'autre, ici orientées dans la direction d'allongement longitudinal, et séparées par une portion centrale, sensiblement perpendiculairement auxdites portions d'extrémité, de manière à présenter une forme générale en marche d'escalier. La lame de connexion 31 est ici enAt least one electrical conductor, here formed by a connecting blade 31, which has two end portions substantially parallel to one another, here oriented in the direction of longitudinal elongation, and separated by a central portion , substantially perpendicular to said end portions, so as to have a general shape staircase. The connecting blade 31 is here in
20 particulier une lame métallique, d'un métal bon conducteur, tel que le cuivre. Particularly a metal blade, a good conducting metal, such as copper.
La lame de connexion est partiellement surmoulée dans le corps 27 et l'appendice 29 du dispositif de connexion 25, de sorte que la portion centrale de la lame de connexion 31 émerge vers l'intérieur du boîtier 19 au niveau de la face de sortie 30 de l'appendice 29 du dispositif de connexion 25. L'extrémité libre de cette portion The connecting blade is partially overmolded in the body 27 and the appendix 29 of the connection device 25, so that the central portion of the connection blade 31 emerges inwardly of the housing 19 at the exit face 30 of the appendix 29 of the connection device 25. The free end of this portion
25 centrale est prolongée par une portion coudée 32 disposée en saillie de la face de sortie de l'appendice et qui relie la portion centrale à l'une des portions d'extrémité qui forme ainsi une partie de lame de connexion émergée 33. Cette partie de lame de connexion émergée 33 s'étend longitudinal ement à partir de l'appendice dans la direction opposée au corps 27 du dispositif de connexion. Ainsi, la partie de lame de connexion émergée25 is extended by a bent portion 32 disposed projecting from the exit face of the appendix and which connects the central portion to one of the end portions which thus forms an emergent connection blade portion 33. This portion An emergentiated connection blade 33 extends longitudinally from the appendage in the opposite direction to the body 27 of the connecting device. Thus, the connection blade portion emerged
30 33 s'étend à l'intérieur du boîtier 19 pour former, à l'intérieur du boîtier, un élément de connexion électrique au circuit intérieur 5 du moteur. La lame de connexion est reliée au circuit extérieur 3 du côté opposé à l'appendice 29. 33 extends inside the housing 19 to form, within the housing, an electrical connection member to the motor internal circuit. The connecting blade is connected to the external circuit 3 on the opposite side to the appendix 29.
En figure 4, le moteur 1 et le dispositif de connexion 25 sont présentés assemblés. L'assemblage se fait selon les étapes suivantes. In Figure 4, the motor 1 and the connecting device 25 are shown assembled. The assembly is done according to the following steps.
En premier, l'appendice 29 et la partie de lame de connexion émergée 33 sont insérés dans l'ouverture 23. La forme de la partie de lame de connexion émergée, en saillie de la face de sortie 30 de l'appendice, et les formes complémentaires de l'appendice 29 et de l'ouverture 23 permettent de disposer la partie de lame de connexion émergée sensiblement le long de la face interne 22 du couvercle 21. On limite ainsi le risque de détérioration des contacts électriques formés par cette partie de lame de connexion émergée 33, puisqu'ils sont protégés par la paroi du couvercle. First, the appendix 29 and the emergent connection blade portion 33 are inserted into the opening 23. The shape of the emergent connection blade portion, projecting from the exit face 30 of the appendix, and the complementary shapes of the appendix 29 and the opening 23 make it possible to arrange the connection blade portion emerging substantially along the inner face 22 of the cover 21. This limits the risk of damage to the electrical contacts formed by this part of connection blade emerged 33, since they are protected by the wall of the lid.
De manière optionnelle, il est alors possible d'enduire la partie de lame de connexion émergée 33 d'un enrobage 35, en une matière isolante telle qu'une résine ou un thermoplastique. L'enrobage 35 isole la partie de lame émergée 33 électriquement et la protège des agressions par la poussière ou l'humidité. Si la partie de lame émergée 33 est de plus parallèle à une paroi du couvercle 21, l'enrobage 35, appliqué le long de la face interne du couvercle, assure une solidité supplémentaire de l'ensemble moteur 1 et dispositif de connexion 25 en collant la partie de lame émergée 33 sur le couvercle 21. D'autres types de solidarisation entre d'une part la partie de lame émergée 33 et son enrobage 35 et d'autre part la paroi du couvercle 21 peuvent être envisagés tels que le soudage et/ou le clipsage et/ou le vissage, de sorte que l'enrobage 35 fait office de moyen de fixation intermédiaire de la partie de lame de connexion émergée 33 par rapport au couvercle et sa face interne 22. Optionally, it is then possible to coat the emerging connection blade portion 33 with a coating 35, made of an insulating material such as a resin or a thermoplastic. The coating isolates the emerged blade portion 33 electrically and protects it from attack by dust or moisture. If the emerging blade portion 33 is further parallel to a wall of the lid 21, the coating 35, applied along the inner face of the lid, provides additional strength of the motor assembly 1 and connection device 25 by gluing. the protruding blade portion 33 on the cover 21. Other types of connection between, on the one hand, the emerged blade portion 33 and its coating 35 and, on the other hand, the wall of the cover 21 may be envisaged, such as welding and / or the clipping and / or screwing, so that the coating 35 serves as an intermediate fixing means of the emerging connection blade portion 33 relative to the lid and its inner face 22.
Les contacts électriques entre la au moins la partie de lame de connexion émergée 33 et le circuit intérieur 5 du moteur 1 sont établis, par exemple par soudure ou serrage. The electrical contacts between the at least the emerging connection blade portion 33 and the internal circuit 5 of the motor 1 are established, for example by welding or clamping.
Ensuite l'appendice 29 est soudé dans l'ouverture 23, afin de rendre l'ensemble étanche. Cette soudure peut par exemple être effectuée par laser ou par ultra-sons. Then the appendix 29 is welded into the opening 23, to make the assembly tight. This welding can for example be performed by laser or ultrasound.
Le couvercle 21 est alors mis en place afin de fermer le boîtier 19 du moteur 1. Le moteur 1 est alors prêt à être monté dans le véhicule. Le montage dans le véhicule comporte essentiellement la fixation du moteur 1 et l'établissement des contacts entre le circuit extérieur 3 et la au moins une lame de connexion 31. The cover 21 is then put in place to close the housing 19 of the engine 1. The engine 1 is then ready to be mounted in the vehicle. The mounting in the vehicle essentially comprises fixing the motor 1 and establishing contacts between the external circuit 3 and the at least one connection blade 31.
Il est à noter que l'étape consistant à enrober la partie de lame de connexion émergée 33 à l'aide d'un enrobage 35 peut être réalisée avant l'insertion de l'appendice 29 et la partie de lame de connexion émergée 33 dans l'ouverture 23. It should be noted that the step of embedding the emergent bonding blade portion 33 with a coating 35 may be performed prior to insertion of the appendix 29 and the emerging bonding blade portion 33 into the opening 23.
L'ouverture 23 et l'appendice 29 peuvent comporter des moyens de coopération de forme qui peuvent être engagés mutuellement par serrage ou par clipsage, en utilisant les marges de déformabilité du matériau plastique dans lequel sont fabriqués le couvercle 21 ou l'appendice 29. The opening 23 and the appendix 29 may comprise means of shape cooperation which can be engaged mutually by clamping or clipping, by using the margins of deformability of the plastic material in which the cover 21 or the appendix 29 is manufactured.
Même si les moyens de coopération de forme sont ultérieurement soudés, par soudure laser, par exemple infra-rouge, ou bien ultra-sons, l'engagement par serrage ou clipsage peut servir lors de l'acheminement et de la manipulation entre les ateliers de montage du couvercle 21 lorsque le dispositif de connexion 25 est implémenté. Ce qui évite tout déplacement du dispositif de connexion par rapport au couvercle 21. Even if the form cooperation means are subsequently welded, by laser welding, for example infra-red, or ultrasound, the engagement by clamping or clipping can be used during the routing and handling between the workshops of mounting the cover 21 when the connection device 25 is implemented. This avoids any displacement of the connection device with respect to the cover 21.
La figure 5 est une vue de dessus de l'ensemble de connexion formé par le couvercle 21 et le dispositif de connexion 25. Sur cette figure 5, les lames de connexion 31 sont au nombre de trois et parallèles. Figure 5 is a top view of the connection assembly formed by the cover 21 and the connection device 25. In this Figure 5, the connecting blades 31 are three in number and parallel.
Le raccord de moteur électrique 1 ainsi obtenu permet un compromis entre connecteurs intégrés et connecteurs rapportés présentant des avantages des deux configurations. The electric motor coupling 1 thus obtained allows a compromise between integrated connectors and inserts having advantages of the two configurations.
En particulier la position finale de l'ouverture 23 et de l'appendice 29 permet en les soudant d'obtenir un dispositif de connexion 25 étanche sur toute sa longueur. In particular, the final position of the opening 23 and the appendix 29 makes it possible, by welding them, to obtain a sealing connection device along its entire length.
De plus, le couvercle du moteur 21 reste standardisé, tandis que le dispositif de connexion peut être adapté à la configuration requise pour l'implémentation finale du moteur selon de multiples réalisations. In addition, the motor cover 21 remains standardized, while the connection device can be adapted to the configuration required for the final implementation of the motor according to multiple embodiments.
Les figures 6 et 7 montrent un second mode de réalisation du dispositif de connexion pour moteur électrique selon l'invention. Figures 6 and 7 show a second embodiment of the connection device for an electric motor according to the invention.
La figure 6 montre une vue en perspective du second mode de réalisation de l'ensemble dispositif de connexion 25 et enrobage 35 avec les lames de connexions 31. Selon ce mode de réalisation, le dispositif de connexion 25 présente une forme cylindrique, l'appendice 29 comprenant une portion cylindrique de même axe de révolution que le corps 27 du dispositif de connexion 25. L'appendice 29 s'étend dans le prolongement du corps 27 selon une direction d'allongement vertical du dispositif de connexion, et la face de sortie s'étend sensiblement dans un plan perpendiculaire à cette direction d'allongement. FIG. 6 shows a perspective view of the second embodiment of the connection device assembly 25 and coating 35 with the connection blades 31. According to this embodiment, the connection device 25 has a cylindrical shape, the appendix 29 comprising a cylindrical portion of the same axis of revolution as the body 27 of the connection device 25. The appendix 29 extends in the extension of the body 27 in a direction of vertical elongation of the connecting device, and the outlet face extends substantially in a plane perpendicular to this direction of elongation.
Dans le mode de réalisation représenté, la portion cylindrique de l'appendice 29 est de diamètre inférieur à celle du corps 27. Le dispositif de connexion 25 présente en outre un second appendice 37, formant dans ce mode de réalisation particulier un connecteur mâle pour la connexion au circuit extérieur 3. In the embodiment shown, the cylindrical portion of the appendix 29 is of smaller diameter than the body 27. The connection device 25 further has a second appendix 37, forming in this particular embodiment a male connector for the connection to the external circuit 3.
Le dispositif de connexion de la figure 6 est montré en coupe en figure 7, dans sa position finale par rapport au couvercle 21. Sur cette figure on peut voir que l'appendice 29 est inséré dans une ouverture 23 ici circulaire, traversant le couvercle depuis la face externe 24 à la face interne 22. The connection device of FIG. 6 is shown in section in FIG. 7, in its final position with respect to the cover 21. In this figure, it can be seen that the appendix 29 is inserted in an opening 23 which is circular here, through the cover from the outer face 24 to the inner face 22.
Par rapport au mode de réalisation précédent, ce mode-ci a l'avantage que le dispositif de connexion 25 peut être tourné dans l'ouverture 23 circulaire, de manière à pouvoir présenter le second appendice 37 formant connecteur mâle dans différentes directions, à la manière d'une tourelle de char. Ces multiples directions possibles sont autant de configurations accessibles sans adaptation supplémentaire. Compared to the previous embodiment, this embodiment has the advantage that the connection device 25 can be turned in the circular opening 23, so as to be able to present the second appendix 37 forming a male connector in different directions, at the way of a tank turret. These multiple possible directions are as many configurations accessible without additional adaptation.
L'invention permet donc de réaliser le couvercle 21 du moteur 1 de manière standardisée pour de multiples configurations, tandis que seul le dispositif de connexion 25 sera adapté au cas par cas pour la connexion du moteur 1. Ceci permet de réaliser des économies d'échelle du côté de la fabrication du couvercle 21, tandis que l'étanchéité attendue est plus importante que celle connue des dispositifs de connexion à connecteur rapporté déjà connus. On comprend que selon l'invention, et tel que cela a été notamment illustré dans chacun des cas décrits, il est avantageux que ces dispositifs de connexion soient configurés pour que la face de sortie de l'appendice affleure avec la face interne du couvercle, apte à être tournée vers l'intérieur du boîtier, et pour que la portion coudée de la lame de connexion entraîne une disposition de la partie de lame émergée le long de la face de sortie et donc le long de la face interne du couvercle. On assure ainsi une disposition des contacts électriques qui sont à la fois en saillie du couvercle, pour faciliter la connexion au circuit intérieur, et à l'abri des chocs, avec ces contacts qui s'étendent parallèlement au couvercle et qui sont donc moins sensible à des déformations que si les contacts s'étendaient perpendiculairement au couvercle. The invention therefore makes it possible to make the cover 21 of the motor 1 in a standardized manner for multiple configurations, whereas only the connection device 25 will be adapted case by case for the connection of the motor 1. This allows savings to be made. scale on the side of the manufacture of the cover 21, while the expected seal is greater than known known connector connection devices already known. It is understood that according to the invention, and as has been illustrated in each of the described cases, it is advantageous that these connection devices are configured so that the output face of the appendix is flush with the inner face of the cover, adapted to be turned towards the inside of the housing, and so that the bent portion of the connecting blade causes an arrangement of the blade portion emerged along the outlet face and thus along the inner face of the lid. This ensures an arrangement of the electrical contacts which are both protruding from the cover, to facilitate the connection to the inner circuit, and protected from shocks, with these contacts extending parallel to the cover and which are therefore less sensitive to deformation than if the contacts extended perpendicular to the cover.
Il est à noter que la lame de connexion précédemment décrite disposée en partie dans le corps 27 peut être remplacée par tout autre conducteur électrique tel qu'un ou des fil(s) électrique(s) et/ou un ou des composant(s) électronique(s). De même, il est possible d'envisager une combinaison de ces éléments, par exemple, deux lames de connexion reliées entre elles par un fil électrique. It should be noted that the previously described connecting blade disposed partly in the body 27 may be replaced by any other electrical conductor such as one or more electric wire (s) and / or component (s) e (s). Similarly, it is possible to envisage a combination of these elements, for example, two connecting blades interconnected by an electric wire.
Selon l'invention, la partie du dispositif de connexion électrique disposée à l'intérieur du boîtier comprend au minimum un élément de connexion électrique adapté pour être connecté au circuit intérieur 5 du moteur électrique 1. Comme décrit précédemment, le dispositif de connexion peut comprendre un conducteur électrique supplémentaire à l'intérieur du boîtier, ici la lame de connexion émergée 33, mais ceci n'est pas obligatoire pour la réalisation de l'invention. According to the invention, the part of the electrical connection device disposed inside the housing comprises at least one electrical connection element adapted to be connected to the internal circuit 5 of the electric motor 1. As described above, the connection device can comprise an additional electrical conductor inside the housing, here the emerging connection blade 33, but this is not mandatory for the embodiment of the invention.
Ce conducteur électrique supplémentaire peut comme décrit précédemment être monobloc avec la lame de connexion 31 ou être constitué par un élément rapporté, ledit élément rapporté pouvant de préférence être porté par un support, telle qu'une plaque conductrice. This additional electrical conductor may as previously described be integral with the connecting blade 31 or be constituted by an insert, said insert can preferably be carried by a support, such as a conductive plate.
