Description

DESCRIPTION DESCRIPTION
TITRE : BOITIER DE PROTECTION DE CONNECTEURS ELECTRIQUES TITLE: PROTECTIVE BOX FOR ELECTRICAL CONNECTORS
[001] La présente invention revendique la priorité de la demande française N°2104342 déposée le 27.04.2021 dont le contenu (texte, dessins et revendications) est ici incorporé par référence. [001] The present invention claims the priority of French application No. 2104342 filed on 04.27.2021, the content of which (text, drawings and claims) is incorporated herein by reference.
[002] L’invention concerne le domaine des protecteurs de connexions électriques, et en particulier la protection de connecteurs d’une batterie de véhicule automobile. [002] The invention relates to the field of electrical connection protectors, and in particular the protection of connectors of a motor vehicle battery.
[003] Cette protection protège des risques de court-circuit entre les connecteurs, mais protège également de risques d’agressions externes comme par exemple suite à l’intervention d’un opérateur pour la maintenance du véhicule ou pendant le transport de la batterie. [003] This protection protects against the risk of short-circuiting between the connectors, but also protects against the risk of external attacks, such as following the intervention of an operator for vehicle maintenance or during transport of the battery.
[004] On connaît du document de brevet CN-A1 -109066924 une batterie comprenant un protecteur comprenant un couvercle articulé autour d’un axe formant une charnière et recouvrant les connecteurs. [004] Patent document CN-A1 -109066924 discloses a battery comprising a protector comprising a cover articulated around an axis forming a hinge and covering the connectors.
[005] Si ce type de dispositif présente l’avantage que le couvercle soit mécaniquement lié à la batterie, et donc imperdable, il a cependant le désavantage que la charnière reste fragile si bien qu’une agression extérieure peut déboiter le couvercle. [005] Although this type of device has the advantage that the cover is mechanically linked to the battery, and therefore cannot be lost, it has the disadvantage that the hinge remains fragile so that an external attack can dislodge the cover.
[006] Le but de l’invention est de remédier à ce manque en proposant un perfectionnement à ce dispositif. [006] The object of the invention is to remedy this lack by proposing an improvement to this device.
[007] A cet effet, l’invention a pour objet un boîtier de protection de connecteurs électriques, ce boîtier comprenant : [007] To this end, the subject of the invention is a protective casing for electrical connectors, this casing comprising:
- une embase destinée à loger les connecteurs électriques, - a base intended to house the electrical connectors,
- un capot destiné à recouvrir l’embase pour, une fois en position fermée sur l’embase, définir un espace enfermant les connecteurs, - a cover intended to cover the base to, once in the closed position on the base, define a space enclosing the connectors,
- un moyen d’articulation pivot articulant le capot sur l’embase entre une position ouverte où les connecteurs sont accessibles et la position fermée, le boîtier comprenant une cloison de séparation électrique destinée à séparer deux connecteurs adjacents, cette cloison étant constituée d’une première partie solidaire de l’embase et d’une deuxième partie solidaire du capot agencées de sorte à se chevaucher si le capot est en position fermée. [008] Ce chevauchement permet un appui supplémentaire du capot sur l’embase, en plus par exemple d’un appui de la périphérie du couvercle sur l’embase. En outre, cet appui supplémentaire peut : - a pivot articulation means articulating the cover on the base between an open position where the connectors are accessible and the closed position, the housing comprising an electrical separation partition intended to separate two adjacent connectors, this partition consisting of a first part secured to the base and a second part secured to the cover arranged so as to overlap if the cover is in the closed position. [008] This overlap allows an additional support of the cover on the base, in addition for example to a support of the periphery of the cover on the base. In addition, this additional support can:
- se situer dans une partie centrale du capot, pour une répartition plus homogène des efforts en cas de choc sur le capot, et/ou - be located in a central part of the bonnet, for a more even distribution of forces in the event of an impact on the bonnet, and/or
- être orienté différemment de l’appui périphérique. - be oriented differently from the peripheral support.
[009] Ainsi une partie de ce choc est mécaniquement reprise par la cloison de séparation électrique tout en préservant l’intégrité du moyen d’articulation pivot, quelle que soit la direction de ce choc, en particulier quand ce choc est orienté dans le plan de l’appui périphérique. [009] Thus part of this shock is mechanically taken up by the electrical partition wall while preserving the integrity of the pivot articulation means, whatever the direction of this shock, in particular when this shock is oriented in the plane peripheral support.
[010] Selon un mode de réalisation de l’invention, la première et la deuxième partie sont en contact l’une sur l’autre si le capot est en position fermée. [010] According to one embodiment of the invention, the first and the second part are in contact with each other if the bonnet is in the closed position.
[011] Ainsi la reprise du choc sur la cloison de séparation est instantanée. En outre ce contact permet une précontrainte mécanique entre la première et deuxième partie, participant ainsi à un verrouillage mécanique du capot sur l’embase. [011] Thus the recovery of the shock on the partition wall is instantaneous. In addition, this contact allows mechanical prestressing between the first and second part, thus contributing to mechanical locking of the cover on the base.
[012] Selon un mode de réalisation de l’invention, la première et la deuxième partie sont agencées de sorte à s’emboiter l’une dans l’autre si le capot est en position fermée. [012] According to one embodiment of the invention, the first and the second part are arranged so as to fit together if the bonnet is in the closed position.
[013] Ainsi quel que soit le sens du choc, ce dernier est repris par la cloison de séparation. [013] Thus, whatever the direction of the shock, the latter is taken up by the partition wall.
[014] Selon un mode de réalisation de l’invention, la première ou la deuxième partie est une double paroi comprenant un espace entre les deux parois, et respectivement la deuxième ou la première partie est une simple paroi destinée à pénétrer l’espace si le capot est en position fermée. [014] According to one embodiment of the invention, the first or the second part is a double wall comprising a space between the two walls, and respectively the second or the first part is a single wall intended to penetrate the space if the hood is in the closed position.
[015] Selon un mode de réalisation de l’invention, la première et/ou la deuxième partie comprennent une surface courbée autour de l’axe de rotation du moyen d’articulation pivot. [015] According to one embodiment of the invention, the first and/or the second part comprise a curved surface around the axis of rotation of the pivot articulation means.
[016] Cette disposition permet une plus grande surface de contact entre les deux parties, et donc une plus grande rigidité de l’assemblage capot / embase, et ceci malgré le fait que le capot ait un mouvement de rotation pour se fermer sur l’embase. [016] This arrangement allows a larger contact surface between the two parts, and therefore greater rigidity of the cover / base assembly, and this despite the fact that the cover has a rotational movement to close on the base.
[017] Selon un mode de réalisation de l’invention, le centre de courbure de la surface courbée est porté par l’axe de rotation du moyen d’articulation pivot. [018] L’invention a également pour objet un boîtier de connexions électriques comprenant : [017] According to one embodiment of the invention, the center of curvature of the curved surface is carried by the axis of rotation of the pivot hinge means. [018] The invention also relates to an electrical connection box comprising:
- le boîtier de protection de connecteurs électriques tel que précédemment décrit,- the electrical connector protection box as previously described,
- deux des connecteurs électriques, comprenant une broche dont l’axe est parallèle à l’axe d’articulation du moyen d’articulation pivot. - two of the electrical connectors, comprising a spindle whose axis is parallel to the axis of articulation of the pivot articulation means.
[019] Selon un mode de réalisation de l’invention, la broche est une tige filetée apte à recevoir une barre omnibus d’une batterie et un écrou serrant cette barre sur la tige filetée. [019] According to one embodiment of the invention, the spindle is a threaded rod capable of receiving a bus bar from a battery and a nut tightening this bar on the threaded rod.
[020] On notera que la barre omnibus peut être remplacée par tout conducteur de courant agencé pour être raccordé à la broche, notamment une cosse électrique sertie ou soudée à l’extrémité d’un câble électrique. Cette cosse comprend par exemple un oeillet traversé par la broche. [020] It will be noted that the bus bar can be replaced by any current conductor arranged to be connected to the pin, in particular an electrical lug crimped or welded to the end of an electrical cable. This terminal comprises for example an eyelet through which the pin passes.
[021] L’invention a également pour objet une batterie comprenant un boîtier de protection tel que précédemment décrit, ou un boîtier de connexions électriques tel que précédemment décrit. [021] The invention also relates to a battery comprising a protective box as described above, or an electrical connection box as described above.
[022] L’invention a également pour objet un véhicule automobile comprenant un boîtier de protection tel que précédemment décrit, ou un boîtier de connexions électriques tel que précédemment décrit. [022] The invention also relates to a motor vehicle comprising a protective box as described above, or an electrical connection box as described above.

[032] Cette cloison 6 est, comme le capot 4 et l’embase 3, réalisée en une matière électriquement isolante, avantageusement issue de moulage avec l’embase 3 et/ou le capot 4. [032] This partition 6 is, like the cover 4 and the base 3, made of an electrically insulating material, advantageously resulting from molding with the base 3 and/or the cover 4.
[033] La première partie 61 solidaire de l’embase 3 est destinée à, pendant une opération de montage consistant à connecter un élément conducteur au connecteur 1, 2, alors que le capot 4 est en position ouverte, éviter l’apparition d’un court-circuit entre les deux connecteurs 1 , 2. Par exemple, si un opérateur utilise une clé métallique pour visser un écrou du connecteur, et que la clé ripe ou est mal positionnée, la première partie 61 empêchera cette mauvaise position et/ou le ripage en faisant obstacle à la clé. Cette première partie 61 est donc destinée à séparer deux connecteurs 1 , 2 adjacents. Telle qu’illustrée sur la figure 2, cette première partie 61 prend la forme de deux « C » accolés dos à dos, et encerclant partiellement chaque connecteur 1, 2. Mais en variante cette première partie 61 peut être une simple cloison plane, ou de toute autre forme. [033] The first part 61 integral with the base 3 is intended, during an assembly operation consisting in connecting a conductive element to the connector 1, 2, while the cover 4 is in the open position, to avoid the appearance of a short-circuit between the two connectors 1, 2. For example, if an operator uses a metal key to screw a nut of the connector, and the key slips or is badly positioned, the first part 61 will prevent this bad position and/or shifting by obstructing the wrench. This first part 61 is therefore intended to separate two adjacent connectors 1, 2. As illustrated in FIG. 2, this first part 61 takes the form of two "C"s joined back to back, and partially encircling each connector 1, 2. But as a variant, this first part 61 can be a simple flat partition, or of any other shape.
[034] La première et la deuxième partie 61 , 62 sont par exemple en contact l’une sur l’autre si le capot 4 est en position fermée. [034] The first and the second part 61, 62 are for example in contact with each other if the cover 4 is in the closed position.
[035] La première et la deuxième partie 61 , 62 sont par exemple agencées de sorte à s’emboîter l’une dans l’autre si le capot 4 est en position fermée. [035] The first and the second part 61, 62 are for example arranged so as to fit one inside the other if the cover 4 is in the closed position.
[036] Un emboîtement est par exemple la première ou la deuxième partie 61 , 62 étant une double paroi comprenant un espace 63 entre les deux parois, et respectivement la deuxième ou la première partie 62, 61 étant une simple paroi destinée à pénétrer l’espace 63 si le capot 4 est en position fermée. [036] A socket is for example the first or the second part 61, 62 being a double wall comprising a space 63 between the two walls, and respectively the second or the first part 62, 61 being a single wall intended to penetrate the space 63 if the cover 4 is in the closed position.
[037] Par exemple la première et/ou la deuxième partie 61 , 62 comprennent une surface courbée 91 , 92 autour de l’axe de rotation du moyen d’articulation pivot 5. [037] For example the first and/or the second part 61, 62 comprise a curved surface 91, 92 around the axis of rotation of the pivot hinge means 5.
[038] Ainsi la surface courbée 91 , 92 présente une concavité en vis-à-vis du moyen d’articulation pivot 5. Dans l’exemple illustré en figure 2, la deuxième partie 62 comprend une première surface courbée 91. Mais la première partie 61 comprend également une deuxième surface courbée 92, qui est l’une des branches de l’un des deux « C » accolés dos à dos. Cette configuration n’est pas obligatoire et, par exemple et comme déjà décrit, la première partie 61 peut être une simple cloison plane alors que la deuxième partie 62 comprend la première surface courbée 91 venant lécher la première partie 61 lors de la fermeture du capot 4. [038] Thus the curved surface 91, 92 has a concavity vis-à-vis the pivot hinge means 5. In the example illustrated in Figure 2, the second part 62 comprises a first curved surface 91. But the first part 61 also includes a second curved surface 92, which is one of the branches of one of the two "C"s joined back to back. This configuration is not obligatory and, for example and as already described, the first part 61 can be a simple flat partition while the second part 62 comprises the first curved surface 91 coming to lick the first part 61 when the cover is closed. 4.
[039] Par exemple, non illustré, le centre de courbure de la surface courbée 91 , 92 est porté par, ou confondu avec l’axe de rotation du moyen d’articulation pivot 5. [039] For example, not shown, the center of curvature of the curved surface 91, 92 is carried by, or coincides with the axis of rotation of the pivot articulation means 5.
[040] On notera que, de façon à maintenir le capot 4 fermé sur l’embase 3, il est avantageux que le boîtier de protection comprenne un moyen de blocage 10 du capot 4 sur l’embase 3, par exemple une vis, ou un clip comme illustré sur la figure 2. Ce moyen de blocage 10 est par exemple avantageusement positionné à une extrémité du capot 4 la plus éloignée du moyen d’articulation pivot 5 mais pas nécessairement. Par exemple, de sorte à réaliser une fermeture du capot 4 inviolable, ce moyen de blocage 10 est un clip positionné sur et verrouillant la première partie 61 sur la deuxième partie 62 : ce clip devenant inaccessible une fois le capot 4 fermé, l’ouverture ultérieure du capot 4 nécessitera à minima la casse de ce clip qui témoignera de l’ouverture du capot 4. [040] It will be noted that, in order to keep the cover 4 closed on the base 3, it is advantageous for the protective casing to comprise a means 10 for locking the cover 4 on the base 3, for example a screw, or a clip as shown in Figure 2. This locking means 10 is for example advantageously positioned at one end of the cover 4 farthest from the pivot hinge means 5 but not necessarily. For example, so as to close the cover 4 inviolably, this blocking means 10 is a clip positioned on and locking the first part 61 on the second part 62: this clip becoming inaccessible once the cover 4 is closed, the opening subsequent cover 4 will require at least the breakage of this clip which will show that cover 4 has been opened.
[041] Ces figures divulguent également un boîtier de connexions électriques comprenant : - le boîtier de protection de connecteurs électriques 1, 2, [041] These figures also disclose an electrical connection box comprising: - the electrical connector protection box 1, 2,
- deux des connecteurs électriques 1, 2, comprenant une broche dont l’axe est parallèle à l’axe d’articulation du moyen d’articulation pivot 5. - two of the electrical connectors 1, 2, comprising a pin whose axis is parallel to the axis of articulation of the pivot articulation means 5.
[042] Par exemple ces connecteurs 1 , 2, longiformes, traversent de part en part l’épaisseur de l’embase 3 de sorte que chacune des deux extrémités des connecteurs électriques 1 , 2 puissent être raccordée électriquement à un circuit électrique 70, 71 , 72 : ainsi est réalisée une connexion électrique étanche au travers de l’embase 3. [042] For example these connectors 1, 2, elongated, cross right through the thickness of the base 3 so that each of the two ends of the electrical connectors 1, 2 can be electrically connected to an electrical circuit 70, 71 , 72: thus a sealed electrical connection is made through the base 3.
[043] La broche est par exemple une tige filetée apte à recevoir une barre omnibus 70 d’une batterie et un écrou non représenté serrant cette barre 70 sur la tige filetée. [043] The spindle is, for example, a threaded rod capable of receiving a bus bar 70 from a battery and a nut, not shown, tightening this bar 70 on the threaded rod.
[044] Par exemple, la première extrémité du connecteur électrique 1 , 2 reçoit la barre omnibus 70, alors que la deuxième extrémité du connecteur électrique 1, 2 reçoit une cosse électrique sertie ou soudée à l’extrémité d’un câble électrique 71. Cette cosse comprend par exemple un oeillet 72 traversé par la broche et serrée sur la broche par un écrou 8. [044] For example, the first end of the electrical connector 1, 2 receives the busbar 70, while the second end of the electrical connector 1, 2 receives an electrical terminal crimped or welded to the end of an electrical cable 71. This terminal includes for example an eyelet 72 through which the pin passes and is tightened on the pin by a nut 8.
[045] Mais d’autres types de connecteurs 1 , 2 sont envisageables, par exemple une broche ayant des moyens de clipage de conducteurs à une extrémité, ou une liaison par soudage avec ce conducteur, ou une liaison par friction et/ou serrage. De même la broche peut être en plusieurs parties, par exemple une tige filetée mâle vissée dans une tige fileté femelle. [045] But other types of connectors 1, 2 are possible, for example a pin having means for clipping conductors at one end, or a connection by welding with this conductor, or a connection by friction and/or clamping. Similarly, the spindle may be in several parts, for example a male threaded rod screwed into a female threaded rod.
[046] En outre, ce boîtier de connexions électriques comprend par exemple un moyen d’étanchéité réalisant une étanchéité entre ces connecteurs 1 , 2 et l’embase 3. L’exemple illustré par la figure 3 divulgue un connecteur 1 , 2 surmoulé dans l’épaisseur de l’embase 3. Ce connecteur comprend par exemple un anneau centré sur l’axe de la broche et noyé dans l’épaisseur de l’embase 3, assurant une tenue mécanique du connecteur 1, 2 dans l’embase 3 et l’étanchéité. [046] In addition, this electrical connection box comprises for example a sealing means providing a seal between these connectors 1, 2 and the base 3. The example illustrated by Figure 3 discloses a connector 1, 2 molded in the thickness of the base 3. This connector comprises for example a ring centered on the axis of the pin and embedded in the thickness of the base 3, ensuring a mechanical strength of the connector 1, 2 in the base 3 and sealing.
[047] Cette invention s’applique par exemple à une batterie et/ou un véhicule automobile comprenant le boîtier de protection ou un boîtier de connexions électriques. Par exemple, pour une batterie alimentant une machine motrice d’un véhicule automobile, l’embase 3 forme une platine d’interface de fixation sur une face d’un bac ou carter de la batterie, et les connecteurs 1 , 2 coïncident avec une ouverture pratiquée dans la paroi du bac ou carter, cette ouverture étant fermée par la platine. En variante, l’embase 3 est issue directement de la matière du bac ou carter, par moulage par exemple, ainsi l’embase 3 est le bac ou carter. [048] On comprendra par batterie, dans tout le texte de ce document, un ensemble comprenant au moins un module de batterie contenant au moins une cellule électrochimique. [047] This invention applies for example to a battery and/or a motor vehicle comprising the protective casing or an electrical connection casing. For example, for a battery supplying a driving machine of a motor vehicle, the base 3 forms an interface plate for fixing on one face of a tray or casing of the battery, and the connectors 1, 2 coincide with a opening made in the wall of the tank or casing, this opening being closed by the plate. As a variant, the base 3 comes directly from the material of the tank or casing, by molding for example, thus the base 3 is the tank or casing. [048] Battery will be understood throughout the text of this document to mean an assembly comprising at least one battery module containing at least one electrochemical cell.
[049] Cette batterie comprend éventuellement des moyens électriques ou électroniques pour la gestion d’énergie électrique de ce au moins un module.[049] This battery optionally comprises electrical or electronic means for managing the electrical energy of this at least one module.
Quand il y a plusieurs modules, ils sont généralement regroupés dans le bac ou carter et forment alors un bloc batteries, ce bloc batteries étant souvent désigné par l’expression anglaise « pack batteries », ce carter contenant généralement une interface de montage, et des bornes de raccordement et formant un espace hermétique autour des modules en les enfermant entre un fond et un couvercle. When there are several modules, they are generally grouped together in the tray or casing and then form a battery pack, this battery pack being often designated by the English expression "battery pack", this casing generally containing an assembly interface, and connection terminals and forming an airtight space around the modules by enclosing them between a bottom and a lid.
[050] Par ailleurs, on comprendra par cellule électrochimique dans tout le texte de ce document, des cellules générant du courant par réaction chimique, par exemple de type lithium-ion (ou Li-ion), de type Ni-Mh, ou Ni-Cd ou plomb ou encore les piles à combustible. [051] Avantageusement, le capot 4 comprend un bord périphérique 11 en appui contre l’embase 3 si le capot 4 est en position fermée. Le boitier de protection comprend par exemple un moyen d’étanchéité comprimé entre ce bord périphérique et l’embase 3. Ce moyen d’étanchéité est par exemple un joint inséré entre le bord périphérique 11 et l’embase 3, ou issu d’un procédé de moulage bi-matière du capot 4 ou de l’embase 3, ou encore un simple recouvrement du bord périphérique 11 avec un bord correspondant de l’embase 3. Par exemple la figure 3 illustre ce bord périphérique 11 pénétrant dans une gorge de l’embase 3, assurant ainsi ce recouvrement. [050] Furthermore, the term electrochemical cell will be understood throughout the text of this document to mean cells generating current by chemical reaction, for example of the lithium-ion (or Li-ion) type, of the Ni-Mh type, or Ni -Cd or lead or even fuel cells. [051] Advantageously, the cover 4 comprises a peripheral edge 11 resting against the base 3 if the cover 4 is in the closed position. The protective case comprises for example a sealing means compressed between this peripheral edge and the base 3. This sealing means is for example a seal inserted between the peripheral edge 11 and the base 3, or resulting from a bi-material molding process of the cover 4 or the base 3, or even a simple covering of the peripheral edge 11 with a corresponding edge of the base 3. For example, FIG. 3 illustrates this peripheral edge 11 penetrating into a groove of the base 3, thus ensuring this covering.
