Description

COLLIER DE MAINTIEN D'UN FAISCEAU ELECTRIQUE  COLLAR FOR MAINTAINING AN ELECTRICAL BEAM
[0001 ] L'invention est relative au montage de faisceaux électriques, notamment au voisinage d'un moteur, et notamment dans un véhicule, comme un véhicule automobile. [0002] Le montage des faisceaux électriques dans un environnement automobile présente un certain nombre de contraintes dont il faut tenir compte. Parmi ceux-ci, il y a un fort encombrement, ce qui signifie devoir éventuellement imposer aux faisceaux électriques un cheminement complexe entre différents organes. Il peut aussi y avoir une contrainte thermique, quand le faisceau chemine dans un environnement à forte température, par exemple près d'un moteur thermique ou de sa ligne d'échappement par exemple. Le faisceau doit aussi généralement être monté de façon à garder une certaine capacité à se déformer, à bouger légèrement, mais il doit aussi être correctement verrouillé en position au niveau de ses points de fixation à la structure du véhicule ou à un organe du véhicule, notamment selon les trois axes véhicule (en X, l'axe longitudinal, en Y, l'axe transversal, et en Z, l'axe vertical en prenant comme référence un véhicule sur un plan horizontal. The invention relates to the assembly of electrical harnesses, especially in the vicinity of an engine, and in particular in a vehicle, such as a motor vehicle. The assembly of electrical harnesses in an automotive environment has a number of constraints that must be taken into account. Among these, there is a large footprint, which means eventually having to impose electrical beams a complex path between different organs. There may also be a thermal stress, when the beam travels in a high temperature environment, for example near a heat engine or its exhaust line for example. The beam must also generally be mounted so as to retain a certain capacity to deform, to move slightly, but it must also be properly locked in position at its points of attachment to the vehicle structure or to a vehicle member, in particular along the three vehicle axes (in X, the longitudinal axis, in Y, the transverse axis, and in Z, the vertical axis taking as reference a vehicle on a horizontal plane.
[0003] Il existe déjà des moyens de maintien et de fixation de composants dans les véhicules à l'aide de colliers de serrage autour d'un organe. On peut par exemple citer la demande de brevet FR 2 856 737, qui décrit un turbocompresseur fixé au bloc-cylindres du moteur par l'intermédiaire d'un collier lié à la bride de raccordement d'une canalisation d'huile. There are already means for holding and fixing components in vehicles using clamps around an organ. For example, patent application FR 2,856,737 describes a turbocharger attached to the engine cylinder block by means of a collar connected to the flange for connecting an oil line.
[0004] Cependant, pour le maintien en position d'un faisceau électrique autour d'un organe, encore faut-il que le collier de maintien puisse entourer complètement l'organe en question, ce qui n'est pas toujours le cas quand l'organe est peu accessible ou est accolé à un autre organe. However, for the holding in position of an electrical harness around an organ, it is still necessary that the retaining collar can completely surround the organ in question, which is not always the case when the organ is not very accessible or is attached to another organ.
[0005] L'invention a pour but une conception améliorée d'un collier de serrage pour maintenir en position un faisceau électrique autour d'un organe, même quand l'organe est peu accessible. The invention aims to an improved design of a clamp for holding in position an electrical harness around an organ, even when the body is not very accessible.
[0006] L'invention a tout d'abord pour objet un collier de maintien d'un faisceau électrique destiné à être disposé autour d'un organe dans une zone cylindrique dudit organe, tel que ledit collier comprend : - une portion de serrage du collier autour de ladite zone cylindrique, ladite portion de serrage comprenant une pince clipsable munie d'une butée de maintien en position de ladite pince; - une portion de maintien du faisceau liée mécaniquement à la portion de serrage et présentant deux moyens de bridage pour le faisceau électrique. The invention firstly relates to a collar for holding an electrical harness intended to be arranged around a member in a cylindrical zone of said member, such as said collar comprises: - a clamping portion of the collar around said cylindrical zone, said clamping portion comprising a clip-on clamp provided with a stop for holding said clamp in position; - A holding portion of the beam mechanically linked to the clamping portion and having two clamping means for the electrical harness.
[0007] Avec ce type de collier, on peut venir serrer la partie de serrage autour d'une zone cylindrique sans que cette partie de serrage n'ait besoin de faire le tour complet de la zone cylindrique. On peut aussi prévoir une multiplication de moyens de bridage sur la portion de maintien du collier, qui autorise, suivant l'espacement des moyens de bridage et le dimensionnement et la forme de la portion de maintien, une grande souplesse de mise en œuvre selon la longueur du segment du faisceau que le collier doit maintenir et selon la forme de son cheminement (rectiligne, courbe...) With this type of collar, one can come tighten the clamping portion around a cylindrical zone without this clamping part need to go around the entire cylindrical area. One can also provide a multiplication of clamping means on the retaining portion of the collar, which allows, according to the spacing of the clamping means and the dimensioning and the shape of the holding portion, a great flexibility of implementation according to the length of the segment of the beam that the collar must maintain and according to the shape of its path (rectilinear, curve ...)
[0008] Selon un mode de réalisation, la pince est une pince en forme de C ou d'Q. According to one embodiment, the clip is a C-shaped or Q-shaped clip.
[0009] Quand la pince est en forme d' Ω, elle peut présenter avantageusement à l'une de ses pattes d'extrémité un prolongement constituant la butée en rotation. When the clamp is in the form of Ω, it may advantageously have at one of its end tabs an extension constituting the stop in rotation.
[0010] On peut prévoir que la pince soit munie sur sa face interne de moyens de retenue anti-rotation, notamment sous forme de griffes (ou d'une surface rugueuse). Les griffes peuvent coopérer avec des butées correspondantes sur l'organe, afin d'assurer le maintien anti rotation et aussi son verrouillage. [001 1 ] Avantageusement, les moyens de bridage peuvent être choisis parmi une pince, de type pince en forme de C ou d'Q ou à charnière, et une agrafe. It may be provided that the clamp is provided on its inner face anti-rotation retaining means, in particular in the form of claws (or a rough surface). The claws can cooperate with corresponding stops on the member, to ensure anti-rotation and also its locking. [001 1] Advantageously, the clamping means may be selected from a clamp, type C or Q-shaped clamp or hinge, and a clip.
[0012] Selon un mode de réalisation, la portion de maintien est monobloc avec la portion de serrage. According to one embodiment, the holding portion is integral with the clamping portion.
[0013] Selon un autre mode de réalisation, la portion de maintien est rapportée sur la portion de serrage (solidarisation par des moyens mécaniques, par collage, par soudure par surmoulage d'une pièce sur l'autre par exemple). According to another embodiment, the holding portion is attached to the clamping portion (securing by mechanical means, by gluing, by molding by overmolding a piece on the other for example).
[0014] La portion de maintien et/ou la portion de serrage peuvent être en métal. L'une ou l'autre peut aussi être à base de matériau polymère, ou être en métal encapsulé au moins en partie par un revêtement en polymère. Dans ce dernier cas de figure, cette encapsulation peut permettre de faciliter le contact entre le collier et l'organe quand la surface de contact de l'organe avec le collier est métallique. The holding portion and / or the clamping portion may be metal. One or the other may also be based on polymeric material, or be metal encapsulated at least in part by a polymer coating. In the latter case, this encapsulation may facilitate contact between the collar and the member when the contact surface of the member with the collar is metallic.
[0015] Dans tous les cas, les matériaux sont choisis de préférence de façon à pouvoir résister à de hautes températures, par exemple d'au moins 1000 C ou d'au moins 1200 C. [0016] Le collier selon l'invention est de préférence muni de moyens d'indexage, du type bossage, doigt, ou creux ou orifice traversant. In all cases, the materials are preferably chosen so as to be able to withstand high temperatures, for example at least 100 ° C. or at least 120 ° C. [0016] The collar according to the invention The invention is preferably provided with indexing means, of the boss type, finger, or hollow or through hole.
[0017] Ces moyens d'indexage peuvent être disposés dans la portion de maintien du faisceau. These indexing means may be arranged in the holding portion of the beam.
[0018] Le collier selon l'invention peut être muni d'un écran thermique. L'écran thermique peut être rapporté sur la portion de serrage. Cet écran thermique peut servir à protéger thermiquement un organe ou composant disposé à son voisinage, par exemple un composant électronique, quand le collier avec son écran se trouve interposé entre un organe émetteur de chaleur (un moteur par exemple, ou une batterie) et un composant électronique comme une carte électronique. Ce composant électronique peut être raccordé au faisceau électrique, notamment par l'intermédiaire d'un connecteur. The collar according to the invention may be provided with a heat shield. The heat shield can be attached to the clamping portion. This heat shield may serve to thermally protect a member or component disposed in its vicinity, for example an electronic component, when the collar with its screen is interposed between a heat emitting member (a motor for example, or a battery) and a electronic component as an electronic card. This electronic component can be connected to the harness, in particular via a connector.
[0019] L'invention a également pour objet un ensemble comprenant le collier de serrage décrit plus haut et un organe présentant une zone cylindrique autour de laquelle la portion de serrage du collier est serrée, et une autre zone sur laquelle est fixée la portion de maintien du faisceau dudit collier. [0020] L'autre zone en question peut être un autre organe, accolé ou au voisinage de l'organe présentant une zone cylindrique, ou un élément de structure (du véhicule par exemple). The invention also relates to an assembly comprising the clamping collar described above and a member having a cylindrical zone around which the tightening portion of the collar is clamped, and another zone on which is fixed the portion of maintaining the bundle of said collar. The other area in question may be another member, adjacent or in the vicinity of the member having a cylindrical zone, or a structural element (of the vehicle for example).
[0021 ] Selon un exemple de réalisation, l'organe est un moteur, électrique ou thermique. According to an exemplary embodiment, the member is a motor, electric or thermal.
[0022] L'ensemble en question peut également comprendre un autre organe, sur lequel la butée du collier s'appuie, directement ou par l'intermédiaire du carter dudit autre organe. Cela peut être également contre cet autre organe que la partie de maintien du collier est fixée. The assembly in question may also include another member, on which the abutment of the collar rests, directly or through the housing of said other member. This can also be against this other organ that the holding part of the collar is fixed.
[0023] Par exemple, l'organe présentant une zone cylindrique est un moteur électrique, l'autre organe est un organe de freinage, ledit ensemble étant destiné à équiper un véhicule, notamment un véhicule automobile. [0024] Avantageusement, le collier est muni de moyens d'indexage coopérant avec des moyens d'indexage complémentaires présents sur un des organes, notamment l'autre organe (celui ne présentant pas la zone cylindrique évoquée plus haut) ou sur une structure, du type doigt/creux ou orifice. [0025] L'invention a également pour objet un procédé de montage du collier dans l'ensemble décrit plus haut, où l'on effectue les opérations successives suivantes : - on met en position la portion de serrage du collier autour de la zone cylindrique de l'organe, - on effectue une rotation de ladite portion de serrage autour de ladite zone jusqu'à la mise en butée de la butée de maintien contre un autre organe, directement ou contre son carter de protection, - on effectue une translation de la portion de serrage pour positionner la portion de maintien du faisceau électrique du collier en regard d'une autre zone dudit organe, puis on vient fixer le faisceau électrique sur ladite portion de par des moyens de bridage. For example, the member having a cylindrical zone is an electric motor, the other member is a braking member, said assembly being intended to equip a vehicle, including a motor vehicle. Advantageously, the collar is provided with indexing means cooperating with complementary indexing means present on one of the organs, in particular the other member (the one not having the cylindrical zone mentioned above) or on a structure, finger / hollow type or orifice. The invention also relates to a mounting method of the collar in the assembly described above, wherein the following successive operations are carried out: - is placed in position the clamping portion of the collar around the cylindrical area of the member, - a rotation of said clamping portion around said area until the abutment of the holding abutment against another member, directly or against its protective housing, - is carried out a translation of the clamping portion for positioning the holding portion of the electrical harness of the collar opposite another area of said member, and then we fix the electrical harness on said portion by clamping means.
[0026] L'invention a également pour objet un véhicule, notamment un véhicule qui comprend l'ensemble décrit plus haut. The invention also relates to a vehicle, including a vehicle that includes the assembly described above.
[0027] L'invention est décrite plus en détail ci-après à l'aide d'un exemple de réalisation non limitatif, illustré à l'aide des figures suivantes, et qui est relatif au montage en deux points d'un faisceau électrique sur un moteur d'un véhicule automobile. The invention is described in more detail below with the aid of a non-limiting embodiment, illustrated with the aid of the following figures, and which relates to the two-point mounting of an electric harness. on an engine of a motor vehicle.
- La figure 1 est une représentation de la zone du véhicule où sont implantés le moteur et le faisceau électrique concernés, le faisceau étant maintenu sur le moteur par le collier selon l'invention, FIG. 1 is a representation of the area of the vehicle in which the motor and the harness concerned are located, the beam being held on the motor by the collar according to the invention;
- La figure 2 est une vue en section du moteur et du dispositif de freinage associé, FIG. 2 is a sectional view of the motor and the associated braking device,
- Les figure 3a et 3b sont des représentations du collier et du faisceau selon la figure 1 sans le moteur, respectivement en position de montage et selon une représentation éclatée, FIGS. 3a and 3b are representations of the collar and the beam according to FIG. 1 without the motor, respectively in the mounting position and according to an exploded representation,
- La figure 4 est une autre vue du collier selon l'invention. - Figure 4 is another view of the collar according to the invention.
[0028] Toutes ces figures sont à considérer comme schématiques et pas nécessairement à l'échelle. Les références identiques d'une figure à l'autre correspondent aux mêmes composants. [0029] La figure 1 représente un faisceau électrique secondaire 1 raccordé par épissure à un faisceau électrique principal 2 circulant sous une traverse inférieure d'un véhicule automobile. Le cheminement de ce faisceau électrique secondaire 1 nécessite des points de bridage de ce dernier afin de le maintenir en position dans une zone où est disposé un moteur électrique 3 qui actionne un organe 4 faisant partie des moyens de freinage du véhicule et qui permet d'amplifier le freinage, et qui sera désigné par la suite par organe de freinage par soucis de concision. Sur l'organe de freinage 4 est monté un carter de protection 5 d'une carte électronique pilotant l'organe et auquel le faisceau électrique secondaire 2 est connecté via un connecteur. Dans l'environnement très encombré de cette zone, il est difficile d'envisager de maintenir le faisceau 2 contre l'organe de freinage 4. Il a été alors envisagé de maintenir le faisceau contre le moteur 3 qui présente une zone cylindrique (le maître- cylindre) qui permet un clipsage d'un collier. All these figures are to be considered as schematic and not necessarily to scale. The identical references from one figure to another correspond to the same components. Figure 1 shows a secondary electrical harness 1 connected by splicing to a main electrical harness 2 flowing under a lower rail of a motor vehicle. The path of this secondary electrical harness 1 requires clamping points of the latter in order to maintain it in position in an area where is disposed an electric motor 3 which actuates a member 4 forming part of the braking means of the vehicle and which makes it possible to to amplify the braking, and which will be designated subsequently by the braking organ for the sake of brevity. On the braking member 4 is mounted a protective housing 5 of an electronic card driving the body and to which the secondary wiring harness 2 is connected via a connector. In the highly congested environment of this zone, it is difficult to envisage keeping the beam 2 against the braking member 4. It was then envisaged to keep the beam against the engine 3 which has a cylindrical zone (the master - cylinder) which allows clipping of a collar.
[0030] La figure 2 représente en section le moteur 3 et l'organe de freinage 4 qui est muni d'un carter de protection 6 : on voit qu'il est difficile d'envisager un collier de serrage aussi bien sur l'organe 4 que sur le moteur 3, dont une partie de la circonférence est très proche du carter 6 donc inaccessible. Figure 2 shows in section the motor 3 and the braking member 4 which is provided with a protective housing 6: we see that it is difficult to envisage a clamp on the body as well 4 that on the engine 3, a part of the circumference is very close to the housing 6 and therefore inaccessible.
[0031 ] L'invention concerne une nouvelle conception de collier de serrage qui comprend deux parties : une portion de serrage 10 et une portion de maintien 1 1 . Comme également détaillé aux figures 3a, 3b et 4, qui seront décrites conjointement avec la figure 1 , la portion de serrage 10 se présente sous la forme d'une pince clipsable ayant la forme d'un oméga Ω. cette portion donc va être facilement clipsée par un opérateur ou de façon automatisée autour de la zone cylindrique du moteur. Une des pattes 10a,10b de l'oméga est prolongée : c'est la patte 10b. Cette patte plus longue que nécessaire à l'opération de clipsage sert de butée de maintien de la pince selon un axe du véhicule, ici l'axe transversal par convention désigné usuellement sous le terme d'axe Y. Elle vient buter, en position de montage, contre un carter 6 de l'organe de freinage 4. The invention relates to a new clamp design which comprises two parts: a clamping portion 10 and a holding portion 1 January. As also detailed in Figures 3a, 3b and 4, which will be described in conjunction with Figure 1, the clamping portion 10 is in the form of a clip-shaped clip having the shape of an omega Ω. this portion will therefore be easily clipped by an operator or automatically around the cylindrical zone of the engine. One of the legs 10a, 10b of the omega is extended: it is the leg 10b. This lug longer than necessary for the clipping operation serves as a stop for holding the clamp along an axis of the vehicle, here the transverse axis by convention usually referred to as the Y axis. It abuts, in the position of mounting, against a housing 6 of the braking member 4.
[0032] La portion de maintien 1 1 se présente sous la forme d'un appendice à la portion de serrage 10, qui est solidaire de celle-ci, et qui présente une zone 1 1 a qui est la zone à proprement dite de raccordement et une zone 1 1 b qui est la zone qui intègre les moyens de bridage du faisceau électrique 1 . La zone 1 1 a s'appuie sur la portion de serrage, la zone 1 1 b se présente sous la forme d'une bande coudée. The holding portion 1 1 is in the form of an appendix to the clamping portion 10, which is integral therewith, and which has a zone 1 1 a which is the actual connection area and a zone 1 1b which is the zone which integrates the clamping means of the electric harness 1. Zone 11a is supported on the clamping portion, zone 11b is in the form of a bent band.
[0033] Dans cet exemple, les portions 10 et 1 1 sont en métal, et la portion 1 1 est rapportée sur la portion 10, par soudage. Alternativement, elles peuvent être à base de polymère, l'une des portions pouvant être surmoulée sur l'autre. Cette zone 1 1 b comprend deux moyens de bridage aptes à fixer le faisceau 2 en deux points : elle présente un premier point de bridage 12 sous forme d'un orifice traversant, et qui va coopérer avec une agrafe du type agrafe sapin pour accrocher le faisceau 2. La zone 1 1 b comprend un deuxième point de bridage 13 (visible sur la figure 3b notamment) qui se présente sous la forme d'une pince clipsable en forme Ω, mais dans des dimensions nettement réduites naturellement par rapport à la pince clipsable de la portion de serrage 10 pour s'adapter cette fois au diamètre du faisceau électrique 2. In this example, the portions 10 and 1 1 are made of metal, and the portion 1 1 is attached to the portion 10, by welding. Alternatively, they can be based on polymer, one of the portions may be overmolded on the other. This zone 1 1b comprises two clamping means capable of fixing the beam 2 at two points: it has a first clamping point 12 in the form of a through hole, and which will cooperate with a staple-type clip fir to hang the beam 2. The zone 1 1 b comprises a second clamping point 13 (visible in FIG. 3b in particular) which is in the form of a clip-shaped clip Ω, but in dimensions that are clearly reduced naturally with respect to the clamp clipping portion of the clamping portion 10 to adapt this time to the diameter of the harness 2.
[0034] L'extrémité de la zone 1 1 b présente aussi (figure 4) un pion 14a disposé sur une des faces de la bande en question, ici sa face interne (par convention par rapport au coude que forme la zone 1 1 b). Ce pion est un moyen d'indexage qui coopère avec un moyen d'indexage complémentaire, en l'occurrence un orifice 14b présent sur l'organe de freinage 4 (visible sur la figure 3b). D'autres moyens d'indexage sont possibles, et on peut notamment prévoir le pion sur l'organe de freinage 4 et le trou sur la zone 1 1 b. [0035] On décrit maintenant la procédure de montage du faisceau 1 avec le collier selon l'invention par un opérateur : - on vient mettre la portion de serrage 10 le collier en position sur la zone cylindrique du moteur 3 en venant la clipser, - puis on effectue une rotation de la portion de serrage 10 pour s'assurer de sa mise en butée par sa butée 10b contre la paroi du carter 6, - on vient ensuite lui faire faire une translation suivant l'axe de la zone cylindrique du moteur pour faire coopérer les moyens d'indexage 14a, 14b, - puis on vient mettre connecter le faisceau à son connecteur (non représenté) à la carte électronique, , - puis on fixe le faisceau au niveau des deux points de bridage 12,13 (clipsage pour le point 13, fixation par agrafe pour le point 12). The end of the zone 1 1 b also has (Figure 4) a pin 14a disposed on one of the faces of the strip in question, here its inner face (by convention relative to the bend that forms the zone 1 1 b ). This pin is an indexing means which cooperates with a complementary indexing means, in this case an orifice 14b present on the braking member 4 (visible in Figure 3b). Other indexing means are possible, and one can in particular provide the pin on the braking member 4 and the hole on the area 1 1 b. We now describe the procedure of mounting the beam 1 with the collar according to the invention by an operator: - it comes to put the clamping portion 10 the collar in position on the cylindrical zone of the motor 3 by coming to clip, - then a rotation of the clamping portion 10 to ensure that it is abutted by its abutment 10b against the wall of the housing 6, - it is then made to make a translation along the axis of the cylindrical zone of the engine to make the indexing means 14a, 14b cooperate, and then connect the beam to its connector (not shown) to the electronic card, and then fix the beam at the two clamping points 12, 13 ( clipping for point 13, fastening by staple for point 12).
[0036] Avec l'invention, on peut donc fixer un faisceau électrique en au moins deux points distants dans l'environnement très encombré /peu accessible d'un moteur accolé à un autre organe. With the invention, it is possible to fix an electrical harness in at least two remote points in the highly congested / poorly accessible environment of an engine attached to another member.
