Description

MANCHON DE PASSAGE D'UN FAISCEAU DE CABLES A TRAVERS UNE CLOISON, NOTAMMENT UN TABLIER DE VEHICULE AUTOMOBILE.  SLEEVE FOR PASSING A WIRING OF CABLES THROUGH A PARTITION, PARTICULARLY A MOTOR VEHICLE APRON.
La présente invention relève des dispositifs utilisés pour le passage des câbles électriques à travers une cloison. L'invention concerne plus particulièrement un tel dispositif agencé en manchon de passage à son travers d'un faisceau de câbles, en procurant une étanchéité entre le manchon et une ouverture de passage du manchon à travers la cloison. Une application de l'invention relève notamment du domaine automobile et concerne plus spécifiquement les dispositifs utilisés pour le passage d'un faisceau de câbles à travers un tablier de séparation entre un compartiment moteur et un habitacle d'un véhicule automobile. The present invention relates to devices used for the passage of electric cables through a partition. The invention relates more particularly to such a device arranged as a sleeve for passage through a bundle of cables, by providing a seal between the sleeve and an opening for passage of the sleeve through the partition. One application of the invention relates in particular to the automotive field and relates more specifically to the devices used for the passage of a bundle of cables through an apron of separation between an engine compartment and a passenger compartment of a motor vehicle.
Les véhicules automobiles comprennent une caisse sur laquelle sont installés divers équipements et/ou accessoires du véhicule. La caisse ménage un compartiment moteur jouxtant l'habitacle du véhicule, qui sont séparés l'un de l'autre par une cloison dénommée tablier. Le compartiment moteur loge les organes participants de la motorisation du véhicule et/ou divers équipements, dont au moins une source d'énergie électrique. Motor vehicles include a body on which various equipment and / or accessories for the vehicle are installed. The body provides an engine compartment adjoining the passenger compartment of the vehicle, which are separated from each other by a partition called an apron. The engine compartment houses the organs involved in motorizing the vehicle and / or various equipment, including at least one source of electrical energy.
Le tablier est couramment formé d'une tôle dont la face orientée vers l'habitacle est pourvue d'une couche d'un matériau d'isolation acoustique, elle- même couverte par une doublure. Ceci permet de préserver les passagers installés à l'intérieur de l'habitacle des nuisances sonores en provenance du compartiment moteur. La source d'énergie électrique est utilisée pour alimenter en électricité divers équipements et/ou accessoires du véhicule qui sont installés hors du compartiment moteur. Il peut aussi être prévu des échanges d'informations entre d'une part des équipements et/ou des accessoires installés dans le compartiment moteur, et d'autre part des équipements et/ou des accessoires installés hors du compartiment moteur. The apron is commonly formed from a sheet whose face facing the passenger compartment is provided with a layer of an acoustic insulation material, itself covered by a lining. This protects passengers installed inside the passenger compartment from noise from the engine compartment. The electric power source is used to supply electricity to various equipment and / or accessories of the vehicle which are installed outside the engine compartment. Information exchanges can also be provided between on the one hand equipment and / or accessories installed in the engine compartment, and on the other hand equipment and / or accessories installed outside the engine compartment.
Par suite, au moins un faisceau de câbles relie d'une part un ou plusieurs équipements et/ou accessoires placés à l'intérieur du compartiment moteur, et d'autre part un ou plusieurs équipements et/ou accessoires placés sur le véhicule à l'extérieur du compartiment moteur. Un tel faisceau de câbles permet par exemple d'acheminer de l'énergie électrique et/ou des signaux de commande depuis le compartiment moteur vers des équipements et/ou des accessoires du véhicule situés hors du compartiment moteur. Consequently, at least one bundle of cables connects on the one hand one or more pieces of equipment and / or accessories placed inside the engine compartment, and on the other hand one or more pieces of equipment and / or accessories placed on the vehicle outside the engine compartment. Such a bundle of cables makes it possible, for example, to route electrical energy and / or control signals from the engine compartment to equipment and / or accessories of the vehicle located outside the engine compartment.
Pour permettre à un faisceau de câbles de s'étendre entre le compartiment moteur et l'habitacle, le tablier comporte au moins une ouverture pour le passage du faisceau de câbles à son travers. Cependant, de l'humidité est susceptible de s'introduire depuis le compartiment moteur vers l'habitacle à travers l'ouverture, ce qui est à éviter. En outre, l'ouverture autorise le passage d'ondes sonores au détriment de l'isolation acoustique de l'habitacle. To allow a bundle of cables to extend between the engine compartment and the passenger compartment, the bulkhead has at least one opening for the passage of the bundle of cables through it. However, moisture is likely to enter from the engine compartment into the passenger compartment through the opening, which is to be avoided. In addition, the opening allows the passage of sound waves to the detriment of the acoustic insulation of the passenger compartment.
C'est pourquoi, il est courant d'interposer un manchon entre le faisceau de câbles et l'ouverture ménagée à travers le tablier, tel qu'il ressort par exemple du document FR2781096-A1 (AUTOMOBILES PEUGEOT SA). Le manchon ceinture le faisceau de câbles et comporte à ses extrémités des lèvres souples prenant appui contre les faces du tablier respectivement orientées vers le compartiment moteur et vers l'habitacle. La lèvre prenant appui contre la face du tablier orientée vers le compartiment moteur est une lèvre d'étanchéité, étant compris vis-à-vis de l'humidité, et la lèvre prenant appui contre la face du tablier orientée vers l'habitacle est une lèvre d'isolation acoustique. This is why it is common to interpose a sleeve between the cable bundle and the opening made through the bulkhead, as shown for example from document FR2781096-A1 (AUTOMOBILES PEUGEOT SA). The sleeve encircles the bundle of cables and comprises at its ends flexible lips bearing against the faces of the bulkhead respectively oriented towards the engine compartment and towards the passenger compartment. The lip bearing against the face of the bulkhead facing the engine compartment is a sealing lip, being understood with respect to humidity, and the lip bearing against the face of the bulkhead facing the passenger compartment is a sound insulation lip.
Dans ce contexte les lèvres sont d'une dimension diamétrale supérieure à celle de l'ouverture. Dès lors, des difficultés se présentent pour l'installation du manchon à travers le tablier, l'une ou l'autre des lèvres faisant obstacle au passage du manchon dans l'ouverture. Une introduction en force de l'une des lèvres à travers l'ouverture rend l'opération de translation du manchon à travers l'ouverture délicate à effectuer par un opérateur, et risque de blesser la lèvre. In this context, the lips are of a diametrical dimension greater than that of the opening. Therefore, difficulties arise for the installation of the sleeve through the apron, one or the other of the lips obstructing the passage of the sleeve in the opening. A force introduction of one of the lips through the opening makes the operation of translating the sleeve through the opening difficult to perform by an operator, and risks injuring the lip.
Par exemple selon des modalités de montage du manchon à travers le tablier, il est plus commode pour un opérateur d'introduire le manchon dans l'ouverture depuis le compartiment moteur vers l'habitacle. Il en ressort que la lèvre d'isolation acoustique fait obstacle au passage de la gaine à travers l'ouverture. Pour forcer son passage à travers l'ouverture, il est alors nécessaire d'exercer une traction et/ou une poussée axiales sur le manchon, mais de telles opérations sont difficiles à effectuer en raison de la résistance de la lèvre. For example, according to methods of mounting the sleeve through the apron, it is more convenient for an operator to introduce the sleeve into opening from the engine compartment to the passenger compartment. It appears that the acoustic insulation lip obstructs the passage of the sheath through the opening. To force its passage through the opening, it is then necessary to exert axial traction and / or thrust on the sleeve, but such operations are difficult to perform due to the strength of the lip.
Pour surmonter ces difficultés, le document FR2781096-A1 propose d'agencer la lèvre d'isolation acoustique en une jupe évasée élastiquement déformable. Au cours de l'installation du manchon à travers l'ouverture, la lèvre d'isolation acoustique est rabattue pour autoriser son passage à travers l'ouverture vers l'habitacle. Il est cependant apparu à l'usage que la mise en œuvre d'une telle solution méritait d'être améliorée. To overcome these difficulties, the document FR2781096-A1 proposes to arrange the acoustic insulation lip in an elastically deformable flared skirt. During the installation of the sleeve through the opening, the acoustic insulation lip is folded down to allow its passage through the opening towards the passenger compartment. However, it has become clear from practice that the implementation of such a solution deserves to be improved.
Dans ce contexte, la présente invention a pour objet un dispositif pour le passage d'un faisceau de câbles électriques à travers une cloison, notamment un tablier de véhicule automobile séparant un compartiment moteur et un habitacle du véhicule. L'invention a aussi pour objet un procédé d'installation à travers une dite cloison d'un dispositif conforme à l'invention. In this context, the present invention relates to a device for the passage of a bundle of electric cables through a partition, in particular a motor vehicle bulkhead separating an engine compartment and a passenger compartment of the vehicle. The invention also relates to a method of installation through a said partition of a device according to the invention.
Le dispositif de l'invention comprend un manchon de traversée de la cloison qui est muni à chacune de ses extrémités de jupes élastiquement déformables formant respectivement une lèvre d'étanchéité de prise d'appui du manchon contre l'une des faces de la cloison et une lèvre d'isolation acoustique de prise d'appui du manchon contre l'autre des faces de la cloison. The device of the invention comprises a sleeve for crossing the partition which is provided at each of its ends with elastically deformable skirts respectively forming a sealing lip for taking the support of the sleeve against one of the faces of the partition and an acoustic insulation lip for supporting the sleeve against the other of the faces of the partition.
Un but de l'invention est de proposer un tel dispositif pour introduire le manchon à travers une ouverture que comporte la cloison, en tenant compte des dimensions des lèvres qui sont significativement supérieures à la dimension de l'ouverture. An object of the invention is to provide such a device for introducing the sleeve through an opening that the partition includes, taking account of the dimensions of the lips which are significantly greater than the dimension of the opening.
Il est notamment visé par l'invention de proposer un tel dispositif dont l'installation à travers l'ouverture est rapide et aisée à réaliser par un opérateur. Un autre but de l'invention est de proposer une solution à moindres coûts, en simplifiant au mieux la structure du dispositif, ses modalités d'obtention, et/ou ses modalités d'installation à travers la cloison. Une telle recherche s'inscrit notamment dans le contexte d'une concurrence économique notoirement sévère dans le domaine automobile, pouvant rendre rédhibitoire une solution potentielle en raison des coûts induits. It is in particular intended by the invention to propose such a device, the installation of which through the opening is quick and easy to carry out by an operator. Another object of the invention is to propose a solution at lower costs, by simplifying as best as possible the structure of the device, its methods of obtaining, and / or its methods of installation through the partition. Such research is particularly in the context of notoriously severe economic competition in the automotive field, which can make a potential solution prohibitive due to the costs involved.
Les buts visés par la présente invention sont atteints isolément ou en combinaison par application des dispositions qui suivent. The aims of the present invention are achieved individually or in combination by applying the following provisions.
Le dispositif de l'invention est un dispositif de passage d'un faisceau de câbles électriques à travers une ouverture ménagée à travers une cloison. Le dispositif comprend un manchon axialement étendu dont l'évidement ménage un couloir de passage du faisceau de câbles à son travers. Le manchon comprend un fût muni à ses extrémités axiales respectives d'une lèvre d'étanchéité et d'une lèvre d'isolation acoustique agencées chacune en jupe évasée élastiquement déformable. Dans ce contexte, l'invention est reconnaissable en ce que l'une quelconque au moins des lèvres est munie d'une pluralité d'organes de saisie de la lèvre qui sont angulairement répartis à proximité de sa périphérie, en ménageant successivement des passages de réception d'un lien amovible de serrage radial de ladite au moins une lèvre. Un enserrement radial de la lèvre par le lien permet de réduire temporairement son extension diamétrale, pour permettre son introduction aisée à travers l'ouverture, et cela sans risque de la blesser. Puis un retrait du lien autorise une application axiale de la lèvre contre la cloison. Le serrage axial de la lèvre étant rompu, une déformation élastique de la lèvre provoque son application axiale contre la cloison. The device of the invention is a device for passing a bundle of electric cables through an opening made through a partition. The device comprises an axially extended sleeve, the recess of which provides a passage for the passage of the cable bundle through it. The sleeve comprises a barrel provided at its respective axial ends with a sealing lip and an acoustic insulation lip each arranged in an elastically deformable flared skirt. In this context, the invention is recognizable in that at least any one of the lips is provided with a plurality of lip gripping members which are angularly distributed close to its periphery, by successively providing passages for receiving a removable radial tightening link of said at least one lip. Radial tightening of the lip by the link makes it possible to temporarily reduce its diametrical extension, to allow its easy introduction through the opening, and this without risk of injuring it. Then removal of the link authorizes an axial application of the lip against the partition. The axial tightening of the lip being broken, an elastic deformation of the lip causes its axial application against the partition.
Plus particulièrement en sortie d'atelier de fabrication du manchon, un opérateur peut aisément installer le lien sur la lèvre et provoquer le serrage radial de la lèvre via le lien jusqu'à réduire son extension à un diamètre de consigne, puis refermer le lien en boucle sur lui-même via ses extrémités jointes l'une à l'autre. Le diamètre de consigne est inférieur au diamètre de l'ouverture à travers laquelle le manchon est destiné à être introduit axialement pour son installation sur la cloison. Le manchon est alors en attente de son utilisation. More particularly at the outlet of the sleeve manufacturing workshop, an operator can easily install the link on the lip and cause the radial tightening. from the lip via the link until reducing its extension to a set diameter, then closing the link in a loop on itself via its ends joined to each other. The nominal diameter is less than the diameter of the opening through which the sleeve is intended to be introduced axially for its installation on the partition. The sleeve is then awaiting use.
Sur un site d'installation du manchon sur la cloison, un opérateur peut alors enfiler aisément le manchon à travers l'ouverture via son extrémité pourvue de la lèvre enserrée par le lien, puis retirer le lien en détachant ses extrémités liées l'une à l'autre et en le retirant des organes de saisie. Le retrait du lien provoque alors le déploiement élastique de la lèvre en application axiale contre la cloison. At a site where the sleeve is installed on the partition, an operator can then easily thread the sleeve through the opening via its end provided with the lip enclosed by the link, then remove the link by detaching its linked ends one by one. the other and by withdrawing it from the seizure organs. The withdrawal of the link then causes the elastic deployment of the lip in axial application against the partition.
L'installation du manchon sur la cloison est rapide et aisée à réaliser par un opérateur, à partir d'un aménagement simple et peu coûteux de la lèvre qui est facile à mettre en œuvre. L'aménagement de la lèvre réside notamment dans la formation des organes de saisie angulairement répartis sur la lèvre suivant une directrice définie par son périmètre, de préférence au plus proche de sa périphérie. Les organes de saisie ménagent ainsi des passages successifs aptes à recevoir collectivement le lien dans l'attente de l'utilisation du manchon. The installation of the sleeve on the partition is quick and easy to carry out by an operator, starting from a simple and inexpensive arrangement of the lip which is easy to implement. The arrangement of the lip resides in particular in the formation of the gripping members angularly distributed over the lip along a director defined by its perimeter, preferably as close as possible to its periphery. The gripping members thus provide successive passages capable of collectively receiving the link while awaiting the use of the sleeve.
Il est compris que l'une quelconque au moins des lèvres est susceptible d'être munie desdits organes de saisie, selon le sens axial d'introduction du manchon à travers l'ouverture. Par exemple, seule la lèvre d'isolation acoustique ou seule la lèvre d'étanchéité peuvent être munies desdits organes de saisie selon un sens de montage de consigne du manchon à travers la cloison. Par exemple encore, les deux lèvres peuvent l'une et l'autre être munies desdits organes de saisie, de sorte que le manchon peut être installé sur la cloison suivant l'un ou l'autre de ses sens opposés d'extension axiale. It is understood that at least any one of the lips is capable of being provided with said gripping members, in the axial direction of introduction of the sleeve through the opening. For example, only the acoustic insulation lip or only the sealing lip can be provided with said gripping members in a set direction of mounting of the sleeve through the partition. For example again, the two lips can both be provided with said gripping members, so that the sleeve can be installed on the partition in one or the other of its opposite directions of axial extension.
Selon une forme avantageuse de réalisation, les organes de saisie sont intégrés à la lèvre qui est notamment issue d'une résine souple, telle qu'un élastomère naturel ou synthétique. Divers modes d'intégration des organes de saisie à la lèvre peuvent être indifféremment mis en œuvre à moindres coûts. According to an advantageous embodiment, the gripping members are integrated into the lip which is in particular derived from a flexible resin, such as a natural or synthetic elastomer. Various methods of integrating the gripping members with the lip can be implemented at lower cost.
Pour exemples, les organes de saisie sont intégrés à la lèvre indifféremment par découpage de la matière constitutive de la lèvre, ou en étant issus de la matière constitutive de la lèvre, ou par scellement. For example, the gripping members are integrated into the lip either by cutting out the material constituting the lip, or by being derived from the material constituting the lip, or by sealing.
Les organes de saisie sont en pluralité en étant angulairement répartis sur la lèvre suivant son extension périphérique, tel que notamment suivant sa circonférence dans le cas courant ou la lèvre est de conformation tronconique. Il est compris ici que la dimension diamétrale d'extension périphérique de la lèvre peut indifféremment être constante depuis l'axe du manchon ou être variable en présentant une conformation d'architecture globalement polygonale dans un plan perpendiculaire à l'axe du manchon. The gripping members are in plurality by being angularly distributed over the lip according to its peripheral extension, such as in particular along its circumference in the current case where the lip is of frustoconical conformation. It is understood here that the diametrical dimension of peripheral extension of the lip can indifferently be constant from the axis of the sleeve or be variable by presenting a conformation of generally polygonal architecture in a plane perpendicular to the axis of the sleeve.
A titre indicatif, le nombre d'organes de saisie est compris entre trois et douze. Selon un cas relevant de l'installation du manchon à travers un tablier d'un véhicule automobile séparant un compartiment moteur d'un habitacle du véhicule, le nombre d'organes de saisie est de huit, plus ou moins deux organes de saisie. Il est compris ici que les organes de saisie sont en pluralité en nombre variable selon la configuration géométrique et/ou la dimension diamétrale de la lèvre. As an indication, the number of seizure bodies is between three and twelve. In one case relating to the installation of the sleeve through an apron of a motor vehicle separating an engine compartment from a passenger compartment of the vehicle, the number of gripping members is eight, plus or minus two gripping members. It is understood here that the gripping members are in plurality in variable number according to the geometric configuration and / or the diametrical dimension of the lip.
La pluralité des organes de saisie leur confère leur aptitude à coopérer collectivement avec le lien, par passage successif du lien de l'un à l'autre des organes de saisie pour permettre le serrage radial de la lèvre par suite d'une traction exercée sur le lien par un opérateur via ses extrémités, préalablement à la fermeture en boucle du lien sur lui-même par jonction de ses extrémités l'une à l'autre. Les modalités de fermeture en boucle du lien sur lui-même sont aisément réversibles pour conférer au lien son caractère amovible sur la lèvre. The plurality of gripping members gives them their ability to cooperate collectively with the link, by successive passage of the link from one to the other of the gripping members to allow the radial tightening of the lip as a result of traction exerted on the link by an operator via its ends, prior to the loop closing of the link on itself by joining its ends to one another. The arrangements for loop closure of the link on itself are easily reversible to give the link its removable nature on the lip.
Différentes variantes de réalisation des organes de saisie peuvent être structurellement simples et aisées à mettre en œuvre à moindres coûts. Pour exemples, les organes de saisie sont chacun formés indifféremment d'un orifice ménagé à travers la lèvre, ou d'un crochet ménagé en saillie sur la lèvre à une face intérieure de la lèvre via laquelle la lèvre prend axialement appui contre la cloison. Different embodiments of the gripping members can be structurally simple and easy to implement at lower costs. For examples, the gripping members are each formed indifferently from an orifice formed through the lip, or from a hook projecting from the lip to an inner face of the lip via which the lip bears axially against the partition.
Différentes variantes de réalisation du lien peuvent aussi être structurellement simples et aisées à mettre en œuvre à moindres coûts. Par exemple, le lien est formé indifféremment d'une ficelle refermée en boucle sur elle- même via un nœud de liaison réversible entre ses extrémités, tel qu'un nœud à au moins une boucle par exemple, ou d'un fil semi-rigide refermé en boucle sur lui- même par vrillage réversible de ses extrémités l'une à l'autre, ou d'un collier de serrage irréversible de ses extrémités l'une à l'autre apte à être rompu au moyen d'un outil tranchant. Different variants of the link can also be structurally simple and easy to implement at lower costs. For example, the link is formed indifferently of a string closed in a loop on itself via a reversible link knot between its ends, such as a knot with at least one loop for example, or of a semi-rigid wire closed in a loop on itself by reversible twist from its ends to one another, or an irreversible clamp from its ends to each other capable of being broken by means of a cutting tool .
Selon une forme de réalisation, la lèvre est jointe au fût via une zone d'affaiblissement de la lèvre ménageant une charnière d'articulation entre la lèvre et le fût. Ceci favorise la déformation élastique de la lèvre depuis sa station déployée vers sa station de serrage radial par le lien, et inversement spontanément depuis sa station de serrage radial par le lien vers sa station déployée par suite du retrait du lien. According to one embodiment, the lip is joined to the barrel via a zone of weakening of the lip providing a hinge for articulation between the lip and the barrel. This promotes the elastic deformation of the lip from its deployed station towards its radial tightening station by the link, and inversely spontaneously from its radial tightening station by the link towards its deployed station as a result of the withdrawal of the link.
De préférence, le manchon est pourvu d'au moins un organe de plaquage forçant une prise d'appui axial élastique de l'une quelconque au moins des lèvres contre la cloison. L'organe de plaquage est notamment affecté au moins à la lèvre d'étanchéité pour conforter l'étanchéité obtenue après installation du manchon sur la cloison. Preferably, the sleeve is provided with at least one plating member forcing an elastic axial support grip of any at least one of the lips against the partition. The plating member is notably assigned at least to the sealing lip to reinforce the sealing obtained after installation of the sleeve on the partition.
L'invention a aussi pour objet un procédé d'installation à travers une cloison d'un manchon participant d'un dispositif conforme à l'invention. The invention also relates to a method of installation through a partition of a sleeve participating in a device according to the invention.
Selon l'invention, le procédé comprend au moins les opérations suivantes effectuées par un opérateur : -) préalablement à l'introduction du manchon à travers l'ouverture ménagée à travers la cloison, mettre en place le lien sur la lèvre en le plaçant successivement en prise sur lesdits organes de saisie. Exercer ensuite un serrage du lien provoquant une déformation radiale de la lèvre jusqu'à l'obtention d'une dimension diamétrale de la lèvre inférieure à celle de l'ouverture, et immobiliser de manière réversible le lien sur lui-même en position de serrage radial de la lèvre. Le manchon est alors en station d'attente de son utilisation. According to the invention, the method comprises at least the following operations carried out by an operator: -) Prior to the introduction of the sleeve through the opening made through the partition, set up the link on the lip by successively placing it in engagement on said gripping members. Then apply a tightening of the link causing a radial deformation of the lip until a diametrical dimension of the lip is less than that of the opening, and immobilize the link in a reversible manner on itself in the tightening position. radial of the lip. The sleeve is then in the waiting station for its use.
-) puis sur site d'installation du manchon sur la cloison, introduire le manchon à travers l'ouverture via l'extrémité du fût munie de la lèvre enserrée par le lien. Puis retirer le lien de la lèvre en rompant son immobilisation réversible sur lui-même, pour autoriser le déploiement élastique de la lèvre contre la cloison.  -) then on the installation site of the sleeve on the partition, introduce the sleeve through the opening via the end of the barrel provided with the lip clamped by the link. Then remove the link from the lip by breaking its reversible immobilization on itself, to allow the elastic deployment of the lip against the partition.
Plus spécifiquement selon une réalisation et par suite du serrage de la lèvre par le lien, la lèvre est rabattue vers l'axe d'extension du manchon en étant orientée en prolongement du fût sensiblement axialement vers l'extérieur du manchon. Il est compris ici que la lèvre rabattue vers l'axe d'extension du manchon est disposé en prolongement axial du fût, en étant potentiellement plus ou moins inclinée par rapport à l'axe du manchon. More specifically according to one embodiment and as a result of the tightening of the lip by the link, the lip is folded down towards the axis of extension of the sleeve while being oriented in extension of the barrel substantially axially towards the outside of the sleeve. It is understood here that the lip folded towards the axis of extension of the sleeve is disposed in axial extension of the barrel, being potentially more or less inclined relative to the axis of the sleeve.
L'invention a aussi pour objet un véhicule automobile reconnaissable en ce qu'il est équipé d'au moins un manchon participant d'un dispositif conforme à l'invention. Ledit au moins un manchon traverse une cloison du véhicule et le lien est retiré de ladite au moins une lèvre munie desdits organes de saisie, qui est appliquée axialement contre la cloison. Il est compris ici que l'absence de lien ne fait pas obstacle à l'identification d'un véhicule de l'invention, dès lors que l'une au moins des lèvres que comprend ledit au moins un manchon en station de traversée de la cloison est identifiable par sa faculté à recevoir le lien via les organes de saisie dont ladite au moins une lèvre est munie. The invention also relates to a motor vehicle recognizable in that it is equipped with at least one sleeve participating in a device according to the invention. Said at least one sleeve passes through a partition of the vehicle and the link is removed from said at least one lip provided with said gripping members, which is applied axially against the partition. It is understood here that the absence of a link does not preclude the identification of a vehicle of the invention, since at least one of the lips that includes said at least one sleeve in the crossing station of the partition is identifiable by its ability to receive the link via the input devices with which said at least one lip is provided.
Plus particulièrement selon une forme de réalisation, ledit au moins un manchon est installé sur un tablier formant une dite cloison de séparation entre un compartiment moteur et un habitacle du véhicule. De préférence, ladite au moins une lèvre munie desdits organes de saisie est la lèvre d'isolation acoustique. More particularly according to one embodiment, said at least one sleeve is installed on an apron forming a said partition between a engine compartment and passenger compartment of the vehicle. Preferably, said at least one lip provided with said gripping members is the acoustic insulation lip.
En effet, l'invention répond particulièrement de manière satisfaisante aux difficultés d'installation d'un dit manchon sur ledit tablier. Selon les opérations successives de montage des accessoires et/ou équipements du véhicule sur une chaîne de montage, il est en effet plus aisé d'introduire le manchon à travers le tablier depuis le compartiment moteur, notamment avant son encombrement par des équipements du véhicule dont notamment sa motorisation. En outre la lèvre d'étanchéité étant de préférence munie d'un dit organe de plaquage contre la cloison, ledit organe de plaque peut faire obstacle à un serrage radial satisfaisant de la lèvre d'étanchéité. Il est dès lors opportun d'appliquer l'invention à la lèvre d'isolation acoustique qui est alors munie desdits organes de saisie. Indeed, the invention responds particularly satisfactorily to the difficulties of installing a said sleeve on said deck. According to the successive operations of mounting the accessories and / or equipment of the vehicle on an assembly line, it is indeed easier to introduce the sleeve through the bulkhead from the engine compartment, in particular before it is encumbered by vehicle equipment, including its engine. In addition, the sealing lip being preferably provided with a said plating member against the partition, said plate member may prevent satisfactory radial tightening of the sealing lip. It is therefore appropriate to apply the invention to the acoustic insulation lip which is then provided with said gripping members.

Les figures et leurs descriptions détaillées d'exemples de réalisation de l'invention peuvent servir à mieux la définir, si besoin en relation avec la description générale qui vient d’en être faite. -) FIG. 6 is composed of two diagrams (c) and (d), successively illustrating in axial half-section the installation methods through a partition of the sleeve shown in FIGS. 2 to 4. The figures and their detailed descriptions show the invention according to particular methods which are not restrictive as to the scope of the invention as defined by the claims.

Sur la figure 1 d'une part et sur les figures 2 à 6 d'autre part, des manchons 101 et 1 a, 1 b en élastomère d'extension axiale A1 , sont configurés pour permettre l'extension d'un faisceau de câbles 2 électriques (figure 1 ) à travers une cloison 3 (figures 5 et 6). Selon une application particulièrement utile de l'invention, la cloison 3 ménage notamment un tablier de cloisonnement entre un compartiment moteur 4a et un habitacle 4b d'un véhicule automobile. Le manchon 101 représenté sur la figure 1 relève de l'art antérieur. Les manchons 1 a, 1 b respectivement représentés d'une part sur les figures 2 à 4 et la figure 6 et d'autre part sur la figure 5, relèvent d'exemples respectifs de réalisation de la présente invention. Les manchons 101 , 1 a, 1 b comprennent essentiellement un fût 105, 5 axialement médian pourvu à ses extrémités axiales respectives de lèvres 106a, 106b, 6a, 6b en élastomère. Les lèvres 106a, 106b, 6a, 6b sont notamment conformées en jupes évasées ou en d'autres termes en jupes de conformation générale tronconique. De tels manchons 101 , 1 a, 1 b sont configurés pour être installés à travers la cloison 3, en étant introduits par translation dans une ouverture 7 que comporte la cloison 3 comme illustré sur la figure 5 et sur les schémas de la figure 6. In FIG. 1 on the one hand and in FIGS. 2 to 6 on the other hand, sleeves 101 and 1 a, 1 b made of elastomer of axial extension A1, are configured to allow the extension of a bundle of cables 2 electric (figure 1) through a partition 3 (figures 5 and 6). According to a particularly useful application of the invention, the partition 3 provides in particular a bulkhead between a motor compartment 4a and a passenger compartment 4b of a motor vehicle. The sleeve 101 shown in Figure 1 is part of the prior art. The sleeves 1a, 1b respectively shown on the one hand in Figures 2 to 4 and Figure 6 and on the other hand in Figure 5, fall under respective embodiments of the present invention. The sleeves 101, 1 a, 1 b essentially comprise a barrel 105, 5 axially median provided at its respective axial ends with lips 106a, 106b, 6a, 6b made of elastomer. The lips 106a, 106b, 6a, 6b are in particular shaped as flared skirts or in other words as skirts of generally frustoconical conformation. Such sleeves 101, 1 a, 1 b are configured to be installed through the partition 3, by being introduced by translation into an opening 7 that comprises the partition 3 as illustrated in FIG. 5 and in the diagrams in FIG. 6.
Les bords périphériques 108a, 108b et 8a, 8b des lèvres 106a, 106b, 6a, 6b sont destinés à prendre respectivement appui axialement contre les faces 3a, 3b opposées de la cloison 3. Une première lèvre est configurée en lèvre d'étanchéité 106a, 6a vis-à-vis d'une infiltration d'humidité à travers l'ouverture 7. Une deuxième lèvre 106b, 6b est configurée en lèvre d'isolation acoustique 106b, 6b faisant obstacle au passage d'ondes sonores à travers l'ouverture 7. The peripheral edges 108a, 108b and 8a, 8b of the lips 106a, 106b, 6a, 6b are intended to bear respectively axially against the opposite faces 3a, 3b of the partition 3. A first lip is configured as a sealing lip 106a, 6a vis-à-vis a moisture infiltration through the opening 7. A second lip 106b, 6b is configured as an acoustic insulation lip 106b, 6b preventing the passage of sound waves through the opening 7.
Sur les figures 5 et 6, la cloison 3 est notamment formée d'un dit tablier. La lèvre d'étanchéité 6a est prévue d'être plaquée contre la face de la cloison 3 orientée vers le compartiment moteur 4a et la lèvre d'isolation acoustique 6b est prévue d'être plaquée contre la face de la cloison 3 orientée vers l'habitacle 4b. De préférence, les manchons 1 a, 1 b sont pourvus d'un organe de plaquage 9 de la lèvre d'étanchéité 6a contre la cloison 3, pour favoriser son application contre la cloison 3 et par suite conforter l'étanchéité obtenue. In Figures 5 and 6, the partition 3 is in particular formed of a said deck. The sealing lip 6a is intended to be pressed against the face of the partition 3 facing the engine compartment 4a and the acoustic insulation lip 6b is intended to be pressed against the face of the partition 3 facing the cockpit 4b. Preferably, the sleeves 1a, 1b are provided with a device 9 for pressing the sealing lip 6a against the partition 3, to promote its application against the partition 3 and consequently reinforce the sealing obtained.
La cloison 3 formée d'un dit tablier comprend une tôle 3a disposée du côté du compartiment moteur 4a. Successivement du côté de la cloison 3 orientée vers l'habitable 4b, la tôle 3a est revêtue d'une couche 3b de matériau d'isolation acoustique, elle-même couverte par une doublure 3c formant une garniture intérieure de l'habitacle 4b. La lèvre d'étanchéité 6a prend ainsi axialement appui contre la tôle 3a et la lèvre d'isolation acoustique 6b prend ainsi axialement appui contre la doublure 3c. Pour permettre le plaquage axial des lèvres 6a, 6b contre la cloison 3, les dimensions D1 a, D1 b diamétrales de leur périphérie sont supérieures à la dimension diamétrale D2 de l'ouverture 7. Ceci pose dès lors le problème des modalités d'introduction des manchons 1 a, 1 b à travers l'ouverture 7, pour leur installation sur la cloison 3. Selon les exemples de réalisation illustrés, les manchons 1 a, 1 b sont de préférence introduits à travers la cloison 3 suivant un sensThe partition 3 formed of a said apron comprises a sheet 3a disposed on the side of the engine compartment 4a. Successively on the side of the partition 3 oriented towards the living space 4b, the sheet 3a is coated with a layer 3b of acoustic insulation material, itself covered by a lining 3c forming an interior lining of the passenger compartment 4b. The sealing lip 6a thus axially bears against the sheet 3a and the acoustic insulation lip 6b thus bears axially against the lining 3c. To allow the axial plating of the lips 6a, 6b against the partition 3, the diametrical dimensions D1 a, D1 b of their periphery are greater than the diametrical dimension D2 of the opening 7. This therefore raises the problem of the methods of introduction sleeves 1 a, 1 b through the opening 7, for their installation on the partition 3. According to the illustrated exemplary embodiments, the sleeves 1 a, 1 b are preferably introduced through the partition 3 in a direction
S1 d'introduction qui est orienté depuis le compartiment moteur 4a vers l'habitacle 4b. S1 introduction which is oriented from the engine compartment 4a to the passenger compartment 4b.
Pour résoudre ce problème, il est proposé par la présente invention une solution pour permettre à un opérateur d'introduire rapidement et aisément un manchon 1 a, 1 b relevant de l'invention à travers l'ouverture 7 que comporte la cloison 3. Une telle opération est réalisée sans risque de blesser la lèvre d'isolation acoustique 6b. La solution proposée par l'invention est structurellement simple et sa mise en œuvre est aisée à effectuer par un opérateur, avec pour avantage de limiter au mieux les surcoûts induits par la solution proposée. To solve this problem, there is proposed by the present invention a solution to allow an operator to quickly and easily introduce a sleeve 1 a, 1 b of the invention through the opening 7 that comprises the partition 3. A such operation is carried out without risk of injuring the isolation lip acoustic 6b. The solution proposed by the invention is structurally simple and its implementation is easy to carry out by an operator, with the advantage of limiting as much as possible the additional costs induced by the proposed solution.
Selon les exemples de réalisation de l'invention illustrés respectivement d'une part sur les figures 2 à 4 et sur la figure 6, et d'autre part sur la figure 5, la lèvre d'isolation acoustique 6b est munie d'une pluralité d'organes de saisie 10a, 10b. Les dits organes de saisie 10a, 10b sont angulairement répartis suivant une directrice définie par l'architecture du périmètre extérieur de la lèvre d'isolation acoustique 6b, qui est par exemple d'architecture circulaire. According to the embodiments of the invention illustrated respectively on the one hand in Figures 2 to 4 and in Figure 6, and on the other hand in Figure 5, the acoustic insulation lip 6b is provided with a plurality seizure bodies 10a, 10b. Said gripping members 10a, 10b are angularly distributed along a direction defined by the architecture of the external perimeter of the acoustic insulation lip 6b, which is for example of circular architecture.
Comme plus particulièrement visible sur les figures 3 et 4, les organes de saisie 10a sont disposés plus ou moins proche du bord périphérique 8b de la lèvre d'isolation acoustique 6b. Les organes de saisie 10a ménagent des passages apte à recevoir collectivement un lien 1 1 amovible refermé en boucle sur lui-même via ses extrémités 1 1 a, 1 1 b, qui s'étend successivement de l'un à l'autre des organes de saisie 10a. Le caractère amovible du lien 1 1 sur la lèvre d'isolation acoustique 6b relève de la faculté par un opérateur de retirer le lien 1 1 par suite d'une rupture de sa fermeture en boucle sur lui-même, comme par exemple par rupture de la liaison des extrémités 1 1 a, 1 1 b du lien 1 1 l'une à l'autre. As more particularly visible in FIGS. 3 and 4, the gripping members 10a are arranged more or less close to the peripheral edge 8b of the acoustic insulation lip 6b. The gripping members 10a provide passages capable of receiving collectively a removable link 1 1 closed in a loop on itself via its ends 1 1 a, 1 1 b, which extends successively from one to the other of the members input 10a. The removable nature of the link 1 1 on the acoustic insulation lip 6b falls within the faculty by an operator to remove the link 1 1 following a rupture of its loop closure on itself, such as for example by rupture of the connection of the ends 1 1 a, 1 1 b of the link 1 1 to each other.
Selon l'exemple de réalisation représenté sur les figures 2 à 4 et sur le schéma (c) de la figure 6, les organes de saisie 10a sont formés d'orifices ménagés à travers la lèvre d'isolation acoustique 6b. De tels orifices sont par exemple formés par découpage de la lèvre d'isolation acoustique 6b. Le lien 1 1 est par exemple formé d'un fil semi-rigide refermé en boucle sur lui-même par vrillage de ses extrémités 1 1 a, 1 1 b l'une à l'autre. According to the embodiment shown in Figures 2 to 4 and in the diagram (c) of Figure 6, the gripping members 10a are formed of orifices formed through the acoustic insulation lip 6b. Such orifices are for example formed by cutting out the acoustic insulation lip 6b. The link 1 1 is for example formed of a semi-rigid wire closed in a loop on itself by twisting its ends 1 1 a, 1 1 b to each other.
Selon l'exemple de réalisation représenté sur la figure 5, les organes de saisie 10b sont formés de crochets qui sont intégrés à la lèvre d'isolation acoustique 6b. Les crochets sont par exemple formés de languettes conformées en équerre qui sont potentiellement issues de la matière constitutive de la lèvre d'isolation acoustique 6b. De tels crochets peuvent être intégrés à la lèvre d'isolation acoustique 6b lors de son moulage, par moulage conjoint ou par surmoulage des crochets sur la lèvre d'isolation acoustique 6b. According to the embodiment shown in FIG. 5, the gripping members 10b are formed of hooks which are integrated into the acoustic insulation lip 6b. The hooks are for example formed by tongues shaped in a square which potentially come from the material of the insulation lip. acoustic 6b. Such hooks can be integrated into the acoustic insulation lip 6b during its molding, by joint molding or by overmolding of the hooks on the acoustic insulation lip 6b.
Sur la figure 2, le lien 1 1 est monté par un opérateur sur la lèvre d'isolation acoustique 6b en sortie d'un atelier de fabrication du manchon 1 a, dans l'attente de son installation sur la cloison 3. A l'issue de cette phase de préparation du manchon 1 a, celui-ci est reconnaissable en ce qu'il est pourvu du lien 1 1 placés en prises successives collectivement avec les organes de saisie 10a. In Figure 2, the link 1 1 is mounted by an operator on the acoustic insulation lip 6b at the outlet of a workshop for manufacturing the sleeve 1 a, pending its installation on the partition 3. At the after this phase of preparation of the sleeve 1a, it is recognizable in that it is provided with the link 1 1 placed in successive sockets collectively with the gripping members 10a.
Sur le schéma (a), l'opérateur enfile le lien 1 1 successivement à travers les organes de saisie 10a formés par les orifices. Puis sur le schéma (b), l'opérateur exerce une traction conjointement sur l'une et l'autre des extrémités 1 1 a, 1 1 b du lien 1 1 , avec pour effet de provoquer un serrage radial de la lèvre d'isolation acoustique 6b pour réduire sa dimension diamétrale d'extension. In diagram (a), the operator threads the link 1 1 successively through the gripping members 10a formed by the orifices. Then in diagram (b), the operator exerts a traction jointly on one and the other of the ends 1 1 a, 1 1 b of the link 1 1, with the effect of causing a radial tightening of the lip of sound insulation 6b to reduce its diametrical extension dimension.
Puis l'opérateur lie entre elles les extrémités 1 1 a, 1 1 b du lien 1 1 à une dimension de consigne D3 d'extension diamétrale de la lèvre d'isolation acoustique 6b. Il est compris ici que la dimension de consigne D3 est inférieure à la dimension diamétrale D2 de l'ouverture 7 que les manchons 1 a, 1 b sont destinés à traverser pour leur montage sur la cloison 3 comme illustré sur le schéma (c) de la figure 6. Then the operator links together the ends 1 1 a, 1 1 b of the link 1 1 to a set dimension D3 of diametrical extension of the acoustic insulation lip 6b. It is understood here that the nominal dimension D3 is less than the diametrical dimension D2 of the opening 7 that the sleeves 1 a, 1 b are intended to pass through for their mounting on the partition 3 as illustrated in the diagram (c) of Figure 6.
Comme illustré sur les figures 3 et 4, la lèvre d'isolation acoustique 6b présente alors une conformation en corolle, par suite du rabat vers l'axe A1 du manchon 1 a des portions de la lèvre d'isolation acoustique 6b s'étendant entre deux organes de saisie 10a voisins l'un de l'autre. As illustrated in FIGS. 3 and 4, the acoustic insulation lip 6b then has a corolla conformation, as a result of the flap towards the axis A1 of the sleeve 1 has portions of the acoustic insulation lip 6b extending between two gripping members 10a adjacent to each other.
Selon l'exemple illustré, les organes de saisie 10a sont au nombre de 8. Il est compris ici que le nombre d'organes de saisie 10a est susceptible de varier selon la dimension diamétrale D1 b de la lèvre d'isolation acoustique 6b en position déployée, en étant en nombre adapté à procurer aisément pour l'opérateur un serrage radial de la lèvre d'isolation acoustique 6b à la dimension de consigne D3. On notera que les modalités d'installation du lien 1 1 sur les organes de saisie 10a qui viennent d'être décrites pour le manchon 1 a relevant du premier exemple de réalisation, sont similaires par transposition à celles d'installation d'un lien 1 1 sur les organes de saisie 10b du manchon 1 b relevant du deuxième exemple de réalisation représenté sur la figure 5. According to the example illustrated, there are 8 gripping members 10a. It is understood here that the number of gripping members 10a is liable to vary according to the diametrical dimension D1 b of the acoustic insulation lip 6b in position deployed, being in a number suitable for easily providing the operator with radial tightening of the acoustic insulation lip 6b to the set dimension D3. It will be noted that the modalities of installation of the link 1 1 on the gripping members 10a which have just been described for the sleeve 1 a pertaining to the first embodiment example, are similar by transposition to those of installing a link 1 1 on the gripping members 10b of the sleeve 1b pertaining to the second embodiment shown in FIG. 5.
Comme illustré sur la figure 2 ainsi que sur les figures 5 et 6, la lèvre d'isolation acoustique 6b est de préférence reliée au fût 5 via une charnière 12, telle que par exemple formée d'un affaiblissement de sa zone de jonction avec le fût 5.As illustrated in FIG. 2 as well as in FIGS. 5 and 6, the acoustic insulation lip 6b is preferably connected to the drum 5 via a hinge 12, such as for example formed by a weakening of its junction zone with the was 5.
Une telle charnière 12 favorise le passage de la lèvre d'isolation acoustique 6b entre d'une part sa station déployée comme illustrée sur le schéma (a) de la figure 2, sur la figure 5 et sur le schéma (d) de la figure 6, et d'autre part sa station d'enserrement radial par le lien 1 1 comme illustré sur le schéma (b) de la figure 2 et sur le schéma (c) de la figure 6. Such a hinge 12 promotes the passage of the acoustic insulation lip 6b between on the one hand its deployed station as illustrated in the diagram (a) of FIG. 2, in FIG. 5 and in the diagram (d) of the FIG. 6, and on the other hand its radial clamping station by the link 1 1 as illustrated in the diagram (b) of FIG. 2 and in the diagram (c) of FIG. 6.
Sur la figure 6 le manchon 1 a préalablement préparé comme illustré sur la figure 2, est installé sur la cloison 3 selon les modalités successivement illustrées sur les schémas (c) et (d). Sur le schéma (c), le manchon 1 a est introduit par translation à travers l'ouverture 7 que comporte la cloison 3, suivant un sens S1 d'introduction prédéfini. Le sens S1 d'introduction du manchon 1 a à travers l'ouverture 7 est notamment défini au regard des positions relatives sur le fût 5 de la lèvre d'isolation acoustique 6b et de la lèvre d'étanchéité 6a. Plus particulièrement suivant le sens S1 d'introduction du manchon 1 a à travers l'ouverture 7, la lèvre d'isolation acoustique 6b est située en amont par rapport à la lèvre d'étanchéité 6a. In FIG. 6 the sleeve 1 previously prepared as illustrated in FIG. 2, is installed on the partition 3 according to the methods successively illustrated in the diagrams (c) and (d). In diagram (c), the sleeve 1 a is introduced by translation through the opening 7 that comprises the partition 3, in a predefined direction S1 of introduction. The direction S1 of introduction of the sleeve 1 a through the opening 7 is notably defined with regard to the relative positions on the barrel 5 of the acoustic insulation lip 6b and of the sealing lip 6a. More particularly in the direction S1 of introduction of the sleeve 1a through the opening 7, the acoustic insulation lip 6b is located upstream relative to the sealing lip 6a.
Pour rappel, la lèvre d'isolation acoustique 6b est serrée par le lien 1 1 à ladite dimension de consigne D3, qui est inférieure à la dimension diamétrale D2 de l'ouverture 7. L'introduction par translation du manchon 1 a à travers l'ouverture 7 peut dès lors être effectuée par l'opérateur sans difficulté particulière, jusqu'à l'application axiale de la lèvre d'étanchéité 6a contre la cloison 3. Les modalités d'installation à travers la cloison 3 du manchon 1 a relevant du premier exemple de réalisation qui viennent d'être décrites, sont similaires par transposition à celles d'installation du manchon 1 b relevant du deuxième exemple de réalisation représenté sur la figure 5. Sur le schéma (d) de la figure 6 et sur la figure 5, l'opérateur retire alors le lien 1 1 de la lèvre d'isolation acoustique 6b. Le lien 1 1 est un élément consommable d'un coût modique qui est alors mis au rebut. L'élasticité structurelle de la lèvre d'isolation acoustique 6b provoque alors son passage en station déployée et par suite son application contre la cloison 3. As a reminder, the acoustic insulation lip 6b is tightened by the link 1 1 to said reference dimension D3, which is less than the diametrical dimension D2 of the opening 7. The introduction by translation of the sleeve 1 a through the opening 7 can therefore be carried out by the operator without any particular difficulty, until the axial application of the sealing lip 6a against the partition 3. The installation methods through the partition 3 of the sleeve 1 a of the first example of embodiments which have just been described, are similar by transposition to those of installation of the sleeve 1b relating to the second exemplary embodiment represented in FIG. 5. In the diagram (d) of FIG. 6 and in FIG. 5, l operator then removes the link 1 1 from the acoustic insulation lip 6b. The link 1 1 is a consumable item of low cost which is then discarded. The structural elasticity of the acoustic insulation lip 6b then causes it to pass into a deployed station and consequently its application against the partition 3.
