Description

L'invention concerne un équipement électrique de véhicule automobile, l'équipement électrique comprenant un dispositif de connexion électrique pour alimenter un équipement électrique de véhicule automobile. L'invention s'applique plus particulièrement aux dispositifs de chauffage et/ou climatisation de véhicules automobiles.The invention relates to an electrical equipment of a motor vehicle, the electrical equipment comprising an electrical connection device for powering an electrical equipment of a motor vehicle. The invention applies more particularly to heating and / or air conditioning devices of motor vehicles.

US 6 178 106 B1 décrit un équipement électrique selon le préambule de la revendication 1. US 6,178,106 B1 describes electrical equipment according to the preamble of claim 1.

Généralement, l'alimentation de l'équipement électrique par une source d'alimentation est assurée par l'intermédiaire d'un ou de plusieurs câbles électriques présentant à une extrémité une cosse et de terminaux d'alimentation correspondants prévus sur l'équipement électrique à alimenter.Generally, the supply of electrical equipment by a power source is provided by means of one or more electrical cables having at one end a terminal and corresponding power terminals provided on the electrical equipment to feed.

Cependant, les câbles électriques peuvent être dirigés selon diverses orientations, par exemple en fonction des gammes de véhicule ou en fonction des options sur une même gamme de véhicule, ce qui nécessite de concevoir à nouveau pour chaque orientation possible la cosse et le terminal d'alimentation.However, the electric cables can be directed according to various orientations, for example depending on the vehicle ranges or depending on the options on the same range of vehicles, which requires to design again for each possible orientation the terminal and the terminal of food.

L'invention a donc pour objectif de pallier cet inconvénient de l'art antérieur en proposant une connexion simplifiée entre un équipement électrique et un câble d'une source d'alimentation pour plusieurs orientations du câble.The invention therefore aims to overcome this disadvantage of the prior art by providing a simplified connection between an electrical equipment and a cable of a power source for several orientations of the cable.

À cet effet, l'invention a pour objet un équipement électrique de véhicule automobile selon la revendication 1.To this end, the subject of the invention is an electrical equipment of a motor vehicle according to claim 1.

  • ladite cosse comporte un corps de forme générale tubulaire complémentaire de l'extrémité dudit câble, pour permettre l'introduction de l'extrémité dudit câble dans ledit corps,
  • ledit équipement électrique comporte une paroi formant butée pour ledit corps de ladite cosse,
  • ladite cosse comporte un moyen de serrage de l'extrémité dudit câble,
  • le moyen de serrage comporte deux demi-brides disposées en quinconce pour ceinturer l'extrémité dudit câble,
  • ledit équipement électrique est un dispositif de chauffage.
The equipment may further include one or more of the following features:
  • said lug has a general shape substantially in "L",
  • said electrical equipment carries at least one holding rib of said terminal, said rib being configured to maintain indifferently one or the other of said portions of said terminal,
  • said rib protrudes from a housing of said electrical equipment in a direction substantially perpendicular to the plane defined by said housing,

  • said lug comprises means for clamping the end of said cable,
  • the clamping means comprises two half-flanges arranged in staggered rows to surround the end of said cable,
  • said electrical equipment is a heater.

D'autres caractéristiques et avantages de l'invention apparaîtront plus clairement à la lecture de la description suivante, donnée à titre d'exemple illustratif et non limitatif, et des dessins annexés parmi lesquels :

  • la figure 1 représente partiellement un équipement électrique relié à un cosse orientée selon une première direction d'arrivée d'un câble,
  • la figure 2 représente partiellement un équipement électrique relié à un cosse orientée selon une seconde direction d'arrivée d'un câble, et
  • la figure 3 illustre un cosse selon l'invention.
Other features and advantages of the invention will emerge more clearly on reading the following description, given by way of illustrative and nonlimiting example, and the appended drawings among which:
  • the figure 1 partially represents electrical equipment connected to a lug oriented in a first direction of arrival of a cable,
  • the figure 2 partially represents electrical equipment connected to a terminal oriented in a second direction of arrival of a cable, and
  • the figure 3 illustrates a pod according to the invention.

Les figures 1 et 2 illustrent un dispositif de connexion 1 pour alimenter un équipement électrique 3 de véhicule automobile, par exemple un dispositif de chauffage électrique de l'air dans le véhicule, l'air réchauffé étant conduit vers des bouches de chauffage et de désembuage/dégivrage pour être distribué sélectivement dans l'habitacle selon les positions de volets de mixage et distribution.The Figures 1 and 2 illustrate a connection device 1 for supplying electrical equipment 3 of a motor vehicle, for example an electric air heating device in the vehicle, the heated air being led to heating and defogging / defrosting vents for distribution selectively in the passenger compartment according to the positions of mixing and distribution flaps.

À cet effet, le dispositif de connexion 1 comporte un terminal d'alimentation 7 porté par exemple par un boîtier 5 de l'équipement électrique 3, ce terminal 7 s'étendant selon une direction d'orientation D et coopérant avec une cosse 9 de connexion reliée à un câble 11 d'une source d'alimentation.For this purpose, the connection device 1 comprises a power supply terminal 7 carried for example by a housing 5 of the electrical equipment 3, this terminal 7 extending in an orientation direction D and cooperating with a lug 9 of connection connected to a cable 11 of a power source.

Cette cosse 9 peut être réalisée par découpage et pliage d'une plaque de tôle.This lug 9 can be made by cutting and folding a sheet metal plate.

Comme on le constate plus visiblement sur la figure 3, la cosse 9 comporte un corps 13 avec une forme générale tubulaire complémentaire de l'extrémité du câble 11, pour permettre l'introduction de l'extrémité du câble 11 dans le corps 13, le câble 11 étant par exemple ensuite soudé sur le corps 13.As can be seen more clearly on the figure 3 , the lug 9 comprises a body 13 with a generally tubular shape complementary to the end of the cable 11, to allow the introduction of the end of the cable 11 into the body 13, the cable 11 being for example subsequently welded to the body 13.

Cette cosse 9 peut comporter en outre un moyen de serrage 15 de l'extrémité du câble 11, par exemple deux demi-brides 15a,15b disposées en quinconce pour ceinturer l'extrémité du câble 11.This lug 9 may further comprise a clamping means 15 of the end of the cable 11, for example two half-flanges 15a, 15b staggered to surround the end of the cable 11.

Afin d'établir un contact avec le terminal d'alimentation 7, on prévoit que la cosse 9 puisse être orientée différemment pour une première direction D1 et pour une seconde direction D2 d'arrivée du câble 11 (voir figures 1 et 2).In order to make contact with the power supply terminal 7, it is expected that the lug 9 can be oriented differently for a first direction D1 and for a second direction D2 of arrival of the cable 11 (see FIG. Figures 1 and 2 ).

Ainsi pour deux directions D1,D2 d'arrivée du câble 11 par rapport au boîtier 5, un même boîtier 5 peut convenir, et c'est la position de la cosse 9 vis-à-vis du terminal 7 qui est adaptée pour pouvoir à la fois établir un contact avec le terminal d'alimentation 7 et avec l'extrémité du câble 11.Thus, for two directions D1, D2 for the arrival of the cable 11 with respect to the housing 5, the same housing 5 may be suitable, and this is the position of the terminal 9 vis-à-vis the terminal 7 which is adapted to be able to both make contact with the supply terminal 7 and with the end of the cable 11.

A cet effet, la cosse 9 comporte une première portion 17a et une seconde portion 17b prolongeant le corps 13 de la cosse 9, chaque portion 17a,17b étant respectivement configurée pour établir un contact avec le terminal d'alimentation 7.For this purpose, the lug 9 includes a first portion 17a and a second portion 17b extending the body 13 of the lug 9, each portion 17a, 17b being respectively configured to establish contact with the power supply terminal 7.

Plus précisément, les deux portions 17a et 17b sont concourantes et en fonction de la direction D1 ou D2 d'arrivée du câble 11, c'est la première 17a ou la seconde 17b portion qui coopère avec le terminal d'alimentation 7 en étant disposée selon une direction sensiblement parallèle à la direction d'orientation D du terminal 7.More precisely, the two portions 17a and 17b are concurrent and, depending on the direction D1 or D2 of the arrival of the cable 11, it is the first 17a or the second portion 17b that cooperates with the supply terminal 7 while being arranged in a direction substantially parallel to the direction of orientation D of the terminal 7.

Par exemple, la cosse 9 présente une forme générale sensiblement en « L » avec les deux portions 17a et 17b perpendiculaires.For example, the lug 9 has a generally "L" -shaped general shape with the two perpendicular portions 17a and 17b.

Ainsi, dans l'exemple illustré sur la figure 1, pour la direction D1 d'arrivée du câble 11, c'est la première portion 17a qui est en contact avec le terminal d'alimentation 7. Au contraire, dans l'exemple illustré sur la figure 2, pour la direction D2 d'arrivée du câble 11, c'est la seconde portion 17b qui est en contact avec le terminal d'alimentation 7.So, in the example shown on the figure 1 for the direction D1 of arrival of the cable 11, it is the first portion 17a which is in contact with the supply terminal 7. On the contrary, in the example illustrated on FIG. figure 2 for the direction D2 of arrival of the cable 11, it is the second portion 17b which is in contact with the supply terminal 7.

Selon ce mode de réalisation, le corps 13 de la cosse, les demi-brides 15a,15b de serrage et les portions 17a et 17b pour le contact avec le terminal 7, sont réalisés d'une seule pièce.According to this embodiment, the body 13 of the terminal, the half-flanges 15a, 15b of clamping and the portions 17a and 17b for contact with the terminal 7, are made in one piece.

Par ailleurs, on peut prévoir que l'équipement électrique 3 porte au moins une nervure de maintien 16a,16b de la cosse 9. Dans cet exemple, le boîtier 5 porte une première 16a et une seconde 16b nervures de maintien, chaque nervure 16a,16b pouvant maintenir indifféremment l'une ou l'autre des portions 17a et 17b de la cosse 9.Moreover, it can be provided that the electrical equipment 3 carries at least one holding rib 16a, 16b of the terminal 9. In this example, the housing 5 carries a first 16a and a second 16b holding ribs, each rib 16a, 16b can maintain indifferently any of the portions 17a and 17b of the pod 9.

Pour cela, la ou les nervures de maintien 16a,16b forment saillie par rapport au boîtier 5 selon une direction verticale, c'est-à-dire sensiblement perpendiculaire au plan P défini par le boîtier 5.For this, the one or more holding ribs 16a, 16b project relative to the casing 5 in a vertical direction, that is to say substantially perpendicular to the plane P defined by the casing 5.

En outre, chaque nervure de maintien 16a,16b peut présenter une forme sensiblement en crochet permettant d'introduire les portions 17a,17b de la cosse 9. Cette introduction se fait selon une direction perpendiculaire au plan P formé par le boîtier 5, quelle que soit la direction d'arrivée D1,D2 du câble 11.In addition, each retaining rib 16a, 16b may have a substantially hook shape for introducing the portions 17a, 17b of the lug 9. This introduction is in a direction perpendicular to the plane P formed by the housing 5, whatever the arrival direction D1, D2 of the cable 11.

On peut prévoir que la ou les nervures 16a,16b sont réalisées en matériau élastique de manière à être déformables pour laisser passer les portions 17a et 17b.It can be provided that the rib or ribs 16a, 16b are made of elastic material so as to be deformable to allow the portions 17a and 17b to pass.

Les nervures de maintien 16a,16b peuvent également présenter un chanfrein, par exemple sur le dessus de la forme en crochet, pour faciliter l'insertion des portions 17a,17b.The holding ribs 16a, 16b may also have a chamfer, for example on the top of the hook shape, to facilitate the insertion of the portions 17a, 17b.

En outre, les deux nervures 16a,16b sont orientées selon deux directions concourantes de façon à former le même angle que les deux portions 17a,17b de la cosse 9, et de sorte qu'une des nervures, ici la seconde nervure de maintien 16b, soit orientée selon une direction sensiblement parallèle à la direction d'orientation D du terminal 7. En effet, comme on le constate sur les figures 1 et 2, cette seconde nervure de maintien 16b fait saillie par rapport au boîtier 5 en regard du terminal 7, quelle que soit l'orientation de la cosse 9 et la direction d'arrivée D1,D2 du câble 11.In addition, the two ribs 16a, 16b are oriented in two concurrent directions so as to form the same angle as the two portions 17a, 17b of the lug 9, and so that one of the ribs, here the second holding rib 16b , is oriented in a direction substantially parallel to the direction of orientation D of the terminal 7. Indeed, as can be seen on the Figures 1 and 2 this second retaining rib 16b protrudes with respect to the housing 5 facing the terminal 7, whatever the orientation of the lug 9 and the arrival direction D1, D2 of the cable 11.

En outre, le boîtier 5 comporte par exemple une paroi 19 contre laquelle le corps de cosse 13 vient en butée lorsque la cosse 9 est orientée selon la direction D1. Pour cela, la paroi 19 est verticale, c'est à dire qu'elle s'étend perpendiculairement par rapport au plan P défini par le boîtier 5.In addition, the housing 5 comprises for example a wall 19 against which the lug body 13 abuts when the lug 9 is oriented in the direction D1. For this, the wall 19 is vertical, that is to say it extends perpendicularly to the plane P defined by the housing 5.

Par ailleurs, on peut prévoir une butée 21 en forme d'arche sous le terminal 7 pour résister aux efforts de traction exercés sur le câble 11.Furthermore, it is possible to provide an arch-shaped abutment 21 under the terminal 7 to withstand the tensile forces exerted on the cable 11.

Cette butée est ajourée en son centre pour permettre le passage d'un outil de soudage par point ou de clinchage de façon à réaliser la liaison électrique entre le terminal 7 et la portion 17a,17b concernée de la cosse 9. Dans ce cas, la seconde nervure 16b faisant saillie en regard du terminal 7 et s'étendant selon la direction d'orientation D, comporte une ouverture identique en vis-à-vis de l'ouverture pratiquée dans la butée 21.This stop is perforated at its center to allow the passage of a spot welding or clinching tool so as to achieve the electrical connection between the terminal 7 and the portion 17a, 17b concerned the pod 9. In this case, the second rib 16b protruding from the terminal 7 and extending in the direction of orientation D, has an identical opening vis-à-vis the opening made in the abutment 21.

On comprend donc qu'un tel dispositif de connexion 1 comportant une cosse 9 pouvant être orientée en fonction de la direction d'arrivée du câble 11 de la source d'alimentation permet d'alimenter un équipement électrique 3 via un seul terminal 7, évitant ainsi de prévoir deux équipements différents pour chaque direction d'arrivée du câble 11.It is therefore understood that such a connection device 1 comprising a lug 9 that can be oriented according to the direction of arrival of the cable 11 of the power source makes it possible to power an electrical equipment 3 via a single terminal 7, avoiding thus to provide two different equipment for each direction of arrival of the cable 11.
