Abstract

The piece (1) has wireways (10a, 10c) to receive electric cables (3a, 3b). A screw (9) is engaged in an orifice (11) of the piece for fixing the piece to a massive unit (5) i.e. gearbox casing. Stops (13, 15) are located remote from and near the orifice, respectively. The stop (13) blocks rotation of the piece when the stop (13) is supported against the massive unit. The stop (15) assures a precise positioning of an axis of the orifice co-axially to a hole (17) of the massive unit when the stop (15) is supported against the massive unit.

Description

L'invention concerne une pièce de maintien d'un câblage électrique sur un organe massif d'un moteur, la pièce présentant une direction principale d'allongement et comprenant une ou plusieurs goulottes où le câblage peut être reçu et des moyens de fixation à l'organe massif. Un problème rencontré sur ce type de pièce est son montage sur l'organe massif concerné du moteur, typiquement un carter de boîte de vitesses, ainsi que le 10 coût de la pièce. L'invention a pour but de prendre en compte de telles considérations et vise à satisfaire tout ou partie des objectifs suivants : - gain en termes de temps et facilité de montage, 15 gain en termes de volume de pièce, réduction de coûts : fabrication et/ou fixation et/ou temps d'installation. Dans ces conditions, il est proposé que la pièce de maintien précitée soit telle que : 20 - les moyens de fixation comprennent exclusivement une vis engagée dans un orifice de la pièce, la pièce comprend en outre une première butée éloignée de l'orifice où est engagée la vis et une seconde butée située à proximité immédiate de cet 25 orifice, - et, lorsque la première butée vient en appui contre l'organe, celle-ci assure un blocage en rotation de la pièce à la manière d'un étrier, tandis que lorsque la seconde butée vient en outre elle-même en appui, un 30 positionnement précis de l'axe de l'orifice de la pièce est assuré, coaxialement au trou de l'organe massif où se fixe la vis. The invention relates to a piece for holding an electrical wiring on a solid member of an engine, the part having a main direction of elongation and comprising one or more chutes where the wiring can be received and fastening means to the massive organ. A problem encountered on this type of part is its mounting on the massive member concerned motor, typically a gearbox housing, and the cost of the part. The invention aims to take into account such considerations and aims to meet all or part of the following objectives: - gain in terms of time and ease of assembly, 15 gain in terms of room volume, cost reduction: manufacturing and / or fixation and / or installation time. Under these conditions, it is proposed that the aforementioned holding piece is such that: - the fixing means comprise exclusively a screw engaged in a hole of the workpiece, the workpiece further comprises a first stop remote from the orifice where is engaged the screw and a second stop located in the immediate vicinity of this orifice, - and, when the first stop bears against the member, it ensures a locking rotation of the workpiece in the manner of a stirrup, while when the second abutment further supports itself, a precise positioning of the axis of the orifice of the part is provided, coaxially with the hole of the massive member where the screw is fixed.

Une présentation encore plus détaillée de la pièce de maintien présentée ci-avant est fournie dans la description qui suit, faite en référence à un mode de réalisation correspondant aux illustrations jointes où : - la figure 1 montre sensiblement de face la pièce de maintien montée sur l'organe massif d'un moteur, - la figure 2 est une vue de l'arrière de la pièce, - et la figure 3 est une vue frontale depuis le bas. Fig.l, on voit une pièce 1, souvent appelée goulotte , de maintien d'un câblage électrique 3 sur un organe massif 5 d'un moteur à explosion. L'organe 5 est un carter de boîte de vitesses. An even more detailed presentation of the holding part presented above is given in the description which follows, made with reference to an embodiment corresponding to the attached illustrations in which: FIG. 1 shows substantially from the front the holding part mounted on the massive member of a motor, - Figure 2 is a view from the rear of the room, - and Figure 3 is a front view from below. Fig.l, we see a piece 1, often called chute, maintaining an electrical wiring 3 on a solid body 5 of a combustion engine. The member 5 is a gearbox housing.

La pièce 1 est. favorablement en matière plastique et présente une direction principale d'allongement la. Elle comprend ici plusieurs goulottes telles que 10a, 10b,10c où des câbles électriques tels 3a,3b peuvent être reçus. Room 1 is. favorably in plastic and has a main direction of elongation la. It comprises here several chutes such as 10a, 10b, 10c where electrical cables 3a, 3b can be received.

Pour la fixation de la pièce 1 à l'organe massif 5, seul un moyen est prévu : une vis 9 engagée dans un orifice 11 de la pièce. L'axe lla de cet orifice est transversal, ici perpendiculaire, à la direction d'allongement la. For fixing the piece 1 to the massive member 5, only one means is provided: a screw 9 engaged in an orifice 11 of the piece. The axis 11a of this orifice is transverse, here perpendicular to the elongation direction 1a.

Pour son positionnement et sa tenue sur l'organe 5, la pièce 1 comprend par ailleurs une première butée 13 éloignée de l'orifice 11 une seconde butée 15 située à proximité immédiate de cet orifice. Sur les figures, l'orifice 11 et la vis 9 s'étendent sensiblement parallèlement à la goulotte principale 10a de la pièce où doit être placée une partie essentielle 3a,3b du câblage devant être maintenu par la pièce, cette goulotte s'étendant transversalement, ici perpendiculairement, à la direction d'allongement la. L'orifice 11 et la vis s'étendent en outre sensiblement parallèlement à cette goulotte 10a, avec ses deux berceaux parallèles et immédiatement adjacents 10al, 10bl (fig.l). Comme on le constate fig.l, lorsque la première butée 13 vient en appui contre l'organe 5, cette butée assure un blocage en rotation de la pièce 1 à la manière d'un étrier. De façon complémentaire, vers l'extrémité longitudinalement opposée, c'est lorsque la seconde butée 15 va venir par ailleurs elle-même en appui contre cet organe qu'un positionnement précis de l'axe lla de l'orifice 11 va être assuré, coaxialement au trou 17 de l'organe 5 où se fixe la vis 9 ; voir fig.l. Sur cette fig.3, on voit d'ailleurs que la goulotte secondaire 3b qui débouche sur la goulotte principale 3a est transversale, ici perpendiculaire, à la direction d'allongement la. Pour une stabilité importante et une efficacité élevée en rotation, la première butée 13 est définie en limite inférieure 10d de la pièce 1, par des parois 13a,13b en forme d'arche évasée vers le bas. For its positioning and holding on the member 5, the part 1 further comprises a first stop 13 remote from the orifice 11 a second stop 15 located in the immediate vicinity of this orifice. In the figures, the orifice 11 and the screw 9 extend substantially parallel to the main chute 10a of the room where must be placed an essential part 3a, 3b of the wiring to be held by the workpiece, this chute extending transversely here perpendicular to the elongation direction la. The orifice 11 and the screw furthermore extend substantially parallel to this chute 10a, with its two parallel and immediately adjacent cradles 10al, 10bl (FIG. 1). As can be seen fig.l, when the first abutment 13 bears against the member 5, this abutment provides rotational locking of the part 1 in the manner of a stirrup. In a complementary manner, towards the longitudinally opposite end, it is when the second stop 15 will also come to bear against this member that a precise positioning of the axis 11a of the orifice 11 will be ensured, coaxially with the hole 17 of the member 5 where the screw 9 is fixed; see fig.l. In this fig.3, we see also that the secondary chute 3b which opens on the main chute 3a is transverse, here perpendicular to the elongation direction la. For high stability and high rotational efficiency, the first stop 13 is defined at the lower limit 10d of the piece 1, by walls 13a, 13b in the form of arch flared down.

Fig.l, on voit qu'ainsi ces parois 13a,13b viennent coiffer l'excroissance 19 inversement évasée de l'organe 5. Pour positionner la pièce 1 sur l'organe, c'est cette première butée 13 que l'on va d'abord ainsi placer. Fig.l, we see that these walls 13a, 13b come to cap the protrusion 19 inversely flared of the member 5. To position the piece 1 on the body, it is this first stop 13 that we go firstly place.

A l'opposé, la seconde butée 15 est favorablement définie par (au moins) un épaulement 150 suivant (au moins) une direction transversale par rapport à la direction d'allongement la. L'épaulement 150 présente une paroi 25a sensiblement parallèle à la direction lla de fixation de 5 l'unique vis 9 et une surface 25b d'appui contre un bord extérieur 50 de l'organe 5. Cette surface d'appui 25b est stable et permet une précision élevée de positionnement de la pièce 1, en particulier de l'orifice 11 par rapport au trou 17. En 10 effet, à cet endroit la seconde butée de la pièce 1 définit localement une cornière 25c, et ce à une extrémité longitudinale notablement éloignée de la zone de la première butée 13. Fig.3, on voit bien que la paroi 25a définit en 15 outre une entretoise entre le voile frontal 250a à travers lequel passe l'orifice 11 et le voile dorsal 250b parallèle au premier et qui, comme lui, est perpendiculaire à l'axe lla, mais est beaucoup plus échancré pour en augmenter la rigidité, puisque le bord 20 intérieur dressé de l'épaulement 150 en forme de cornière d'extrémité définit donc la surface d'appui 25b. Pour monter la pièce 1 sur l'organe 5, on la présente d'abord par-dessus cet organe puisqu'elle en surmonte localement un bord supérieur. On installe la 25 première butée 13 : on fait coiffer l'excroissance 19 par les parois 13a,13b qui assurent un positionnement en rotation. L'ajustement définitif s'opère par le calage de la seconde butée 15 dont la surface d'appui 25b, dressée 30 sensiblement parallèlement à la direction 130 suivant laquelle se développe l'étrier 13, positionne précisément l'axe lia par rapport à l'axe du trou 17. In contrast, the second stop 15 is favorably defined by (at least) a shoulder 150 following (at least) a direction transverse to the elongation direction la. The shoulder 150 has a wall 25a substantially parallel to the direction lla for fixing the single screw 9 and a bearing surface 25b against an outer edge 50 of the member 5. This bearing surface 25b is stable and allows a high positioning accuracy of the part 1, in particular of the orifice 11 with respect to the hole 17. In fact, at this point the second abutment of the part 1 locally defines a bracket 25c, and this at a longitudinal end significantly away from the area of the first stop 13. Fig.3, it is clear that the wall 25a further defines a spacer between the front web 250a through which the hole 11 and the dorsal web 250b parallel to the first and which, like it, is perpendicular to the axis 11a, but is much more indented to increase its rigidity, since the upright inner edge of the shoulder-shaped shoulder 150 thus defines the bearing surface 25b . To mount the piece 1 on the member 5, it is first of all above this body since it locally surmounts an upper edge. The first abutment 13 is installed: the protrusion 19 is capped by the walls 13a, 13b which provide rotational positioning. The final adjustment is effected by the wedging of the second stop 15 whose bearing surface 25b, erected substantially parallel to the direction 130 in which the stirrup 13 develops, precisely positions the axis 11a with respect to the Hole axis 17.

On aura noté que la direction 130 est transversale à la fois à la direction la et à l'axe lla. It will be noted that the direction 130 is transverse both to the direction la and to the axis 11a.
