Description

La présente invention concerne un élément électrique de véhicule routier.The present invention relates to an electrical element of road vehicle.

Dans un véhicule de transport routier, tel que notamment une remorque de poids lourd, l'alimentation électrique est assurée par l'intermédiaire d'une boíte de dérivation.In a road transport vehicle, such as in particular a heavy-duty trailer, the power supply is provided by means of a junction box.

Cette dernière reçoit, d'une part, des câbles d'alimentation principale et se trouve, d'autre part, en communication électrique avec des éléments annexes tels que des feux, par l'intermédiaire de plusieurs câbles conducteurs annexes.The latter receives, on the one hand, power cables main and is, on the other hand, in communication electric with ancillary elements such as lights, for example through several additional conducting cables.

Le montage d'un câble conducteur sur un élément électrique, tel que la boíte de dérivation ou les feux précités, consiste tout d'abord à ménager un orifice dans la paroi de cet élément. Puis, il s'agit de faire passer les brins conducteurs au travers de cet orifice et de les connecter sur un organe de raccord, tel qu'une languette. On rapporte enfin, entre les brins conducteurs et les parois en regard de l'orifice, un presse-étoupe assurant à la fois un maintien mécanique, ainsi qu'une fonction d'étanchéité.The mounting of a conductive cable on an electrical element, such as the junction box or the aforementioned lights, consists first of all in providing an orifice in the wall of this element. Then, it is a question of passing the strands conductors through this hole and connect them on a connecting member, such as a tongue. Finally, between the conductive strands and the walls opposite the orifice, a cable gland ensuring both a maintenance mechanical, as well as a sealing function.

Cette solution connue implique cependant certains inconvénients.This known solution, however, involves certain disadvantages.

En effet, selon une première alternative, il est envisageable de procéder au montage des éléments électriques et de leurs câbles conducteurs, au sein même de l'usine de fabrication. La mise en place par le client de l'ensemble ainsi formé, est alors délicate et pénible, et s'avère de surcroít impossible dans certaines configurations du véhicule routier.Indeed, according to a first alternative, it is possible to proceed with the assembly of electrical elements and their conductive cables, within the factory of manufacturing. The installation by the client of the whole thus formed, is then delicate and painful, and turns out to be moreover impossible in certain vehicle configurations road.

A titre de variante, le client est à même de fixer les différents feux, non raccordés, sur le véhicule routier. Puis, il fait passer les brins conducteurs du câble au travers de l'orifice et les raccorde à l'organe de connexion dont est muni le feu. Il doit ensuite procéder au montage d'une ampoule, ainsi que d'un capot de protection du feu.Alternatively, the client is able to set the different lights, not connected, on the road vehicle. Then, it passes the conductive strands of the cable through the orifice and connects them to the connection member which is provided the fire. He must then proceed with the assembly of a bulb, as well as a fire protection hood.

Une telle mise en place est particulièrement longue et fastidieuse pour l'utilisateur. Elle implique en outre la nécessité de stocker et de livrer de nombreux accessoires séparés, ce qui est désavantageux en termes de maintenance.Such an installation is particularly long and tedious for the user. It also involves the need to store and deliver many accessories separate, which is disadvantageous in terms of maintenance.

L'invention se propose de pallier l'ensemble des inconvénients de l'art antérieur évoqués ci-dessus.The invention proposes to overcome all of the disadvantages of the prior art mentioned above.

A cet effet, elle a pour objet un élément électrique de véhicule routier, notamment un feu électrique, comprenant un corps, caractérisé en ce qu'il est pourvu d'au moins une première partie de connecteur comportant des moyens de fixation amovible dans un orifice d'une paroi dudit élément électrique, cet orifice étant apte à recevoir en outre, de manière amovible, un presse-étoupe, et en ce que cette première partie de connecteur définit un premier logement de réception de premiers éléments de connexion électrique, dont chacun peut être connecté avec un premier brin électrique correspondant, reçu dans le volume intérieur de l'élément électrique.To this end, it relates to an electrical element of road vehicle, in particular an electric fire, comprising a body, characterized in that it is provided with at least one first connector part comprising means for removable fixing in an orifice of a wall of said element electric, this orifice being able to receive, in addition, removable, a cable gland, and in that this first connector part defines a first housing of reception of the first electrical connection elements, including each can be connected with a first electrical strand corresponding, received in the interior volume of the element electric.

L'invention va être décrite ci-dessous, en référence aux dessins annexés, donnés uniquement à titre d'exemple non limitatif et dans lesquels :

  • la figure 4 est une vue en coupe longitudinale, illustrant le connecteur des figures 2 et 3 une fois monté sur l'élément électrique précité.
The invention will be described below, with reference to the accompanying drawings, given only by way of non-limiting example and in which:
  • Figure 1 is a top view, in partial section, illustrating an electric element of a road vehicle according to the invention;
  • Figure 2 is a longitudinal sectional view, exploded exploding the various components of a connector fitted to the electrical element of Figure 1;

La figure 1 représente un élément électrique 2 appartenant à un véhicule routier tel qu'une remorque de poids lourd. Dans le présent exemple, cet élément électrique est un feu, mais il peut également s'agir, entre autres, d'une boíte de dérivation.Figure 1 shows an electrical element 2 belonging to a road vehicle such as a truck trailer. In this example, this electrical element is a fire, but it can also be, among other things, a box of derivation.

Le feu 2 comprend un corps 4, fermé par un capot translucide 6, qui définit un volume intérieur V de ce feu. Il est équipé de façon classique d'une ampoule 8, destinée à être alimentée par des languettes de connexion électrique 10. The light 2 comprises a body 4, closed by a cover translucent 6, which defines an interior volume V of this light. It is conventionally equipped with a bulb 8, intended for be powered by electrical connection tabs 10.

Ce feu 2 est muni de deux connecteurs de raccordement électrique, dont chacun est désigné dans son ensemble par la référence 12. Chaque connecteur comprend une première partie 14, solidarisée sur la paroi 16 du corps 4, opposée au capot 6. Par ailleurs, une seconde partie 18 du connecteur 12 est susceptible d'être solidarisée sur une première partie 14 correspondante, comme cela est explicité dans ce qui suit, en référence aux figures 2 à 4.This light 2 is provided with two connection connectors electric, each of which is designated as a whole by the reference 12. Each connector includes a first part 14, secured to the wall 16 of the body 4, opposite the cover 6. Furthermore, a second part 18 of the connector 12 is likely to be joined on a first part 14 corresponding, as explained in the following, in reference to Figures 2 to 4.

Comme le montre la figure 2, la première partie 14 du connecteur 12 comprend un élément de raccord mécanique 20, de forme à peu près cylindrique. Cet élément 20 comporte un col fileté 22 terminé par un épaulement périphérique 24, lui même prolongé par un fût 26. Ce dernier possède un tronçon d'actionnement 28 hexagonal, adjacent au col 22 et susceptible d'entrer en prise avec un outil à six pans, non représenté. Par ailleurs, ce fût 26 possède une partie filetée 30, opposée au col 22, dont les parois intérieures délimitent un siège 32 de réception d'un joint.As shown in Figure 2, the first part 14 of the connector 12 includes a mechanical connection element 20, roughly cylindrical shape. This element 20 has a neck threaded 22 terminated by a peripheral shoulder 24, itself extended by a barrel 26. The latter has a section 28 hexagonal actuator, adjacent to collar 22 and susceptible to engage with a hexagon tool, not shown. Furthermore, this barrel 26 has a threaded part 30, opposite at collar 22, the interior walls of which define a seat 32 receiving a seal.

Le col 22 est muni d'un voile médian 34, définissant deux rebords rentrants 36, permettant l'accrochage d'un élément de connexion électrique. On note 38 le logement s'étendant au voisinage de ces rebords rentrants 36. Par ailleurs, la paroi intérieure de cet élément 20 est munie d'un ergot axial 40 d'indexation, destiné à pénétrer dans une rainure d'un élément de raccord complémentaire, comme cela sera décrit dans ce qui suit.The neck 22 is provided with a median veil 34, defining two inside edges 36, allowing the attachment of an element of electrical connection. We note 38 the housing extending to vicinity of these re-entrant edges 36. Furthermore, the wall interior of this element 20 is provided with an axial lug 40 indexing, intended to enter a groove of an element of complementary fitting, as will be described in what follows.

La première partie 14 du connecteur 12 comprend également un écrou hexagonal 42, dont la paroi intérieure taraudée est destinée à loger le col fileté 22. Cet écrou est susceptible d'être inséré dans un orifice hexagonal correspondant, ménagé dans la paroi 16 du feu 2. Il est par ailleurs prévu un joint plat 44, apte à être interposé entre les parois en regard de l'écrou 42 et de l'épaulement 24.The first part 14 of the connector 12 also includes a hexagonal nut 42, the internal threaded wall of which is intended to accommodate the threaded neck 22. This nut is susceptible to be inserted into a corresponding hexagonal hole, provided in the wall 16 of the light 2. There is also provided a seal flat 44, able to be interposed between the walls opposite the nut 42 and the shoulder 24.

Il est à noter que l'écrou 42 est apte à recevoir également, de façon amovible, un presse-étoupe classique, non représenté. A cet effet, un organe fileté de ce presse-étoupe est à même de coopérer avec la paroi intérieure taraudée de l'écrou 42. It should be noted that the nut 42 is suitable for receiving also, removably, a conventional cable gland, not represented. For this purpose, a threaded member of this cable gland is able to cooperate with the internal threaded wall of nut 42.

La première partie 14 comprend enfin plusieurs éléments de connexion électrique, ou cosses, dont chacun est désigné par la référence 46. Chaque cosse est pourvue d'une extrémité 48 de fixation sur un brin conducteur non représenté, ainsi qu'une tige 50 destinée à pénétrer dans un élément de connexion femelle. Enfin, chaque cosse 46 est munie d'une branche rentrante 52, destinée à coopérer avec un rebord 36 correspondant.The first part 14 finally comprises several elements electrical connection, or lugs, each of which is designated by reference 46. Each terminal has one end 48 for attachment to a conductive strand not shown, thus that a rod 50 intended to penetrate an element of female connection. Finally, each terminal 46 is provided with a re-entrant branch 52, intended to cooperate with a rim 36 corresponding.

La seconde partie 18 du connecteur 14 comprend un élément de raccord mécanique 54, de forme cylindrique. Ce dernier comporte un fût 56 dont la périphérie extérieure est pourvue de nervures de renfort 58. Ce fût est terminé par un épaulement périphérique 60, destiné à former butée pour un joint torique 61. Cet épaulement délimite un col d'extrémité 62, dont les parois intérieures forment un siège 64.The second part 18 of the connector 14 comprises an element mechanical connection 54, cylindrical in shape. This last has a barrel 56 whose outer periphery is provided of reinforcing ribs 58. This barrel is terminated by a shoulder peripheral 60, intended to form a stop for a joint O-ring 61. This shoulder delimits an end neck 62, the interior walls of which form a seat 64.

Comme le montre la figure 1, ce fût 56 est creusé d'une rainure axiale 66, destinée à coopérer avec l'ergot 40.As shown in Figure 1, this barrel 56 is hollowed out axial groove 66, intended to cooperate with the lug 40.

En faisant à nouveau référence à la figure 2, l'élément 54 est pourvu d'un voile médian 68 se prolongeant, au-delà du col 62, par une saillie axiale 70, destinée à la séparation de deux brins conducteurs non représentés.Referring again to Figure 2, the element 54 is provided with a median veil 68 extending beyond the neck 62, by an axial projection 70, intended for separation of two conductive strands not shown.

Enfin, le fût 56 est pourvu, sur sa paroi intérieure, de doigts rentrants 72, destinés à recevoir un élément de connexion électrique. Ces doigts 72 définissent, avec le voile 68, des alvéoles 74 de réception de ces éléments de connexion.Finally, the barrel 56 is provided, on its inner wall, with re-entrant fingers 72, intended to receive an element of electrical connection. These fingers 72 define, with the veil 68, cells 74 for receiving these connection elements.

Il est prévu deux éléments de connexion électrique 76, ou cosse, dont chacun est destiné à coopérer avec un élément 46 correspondant. Chaque cosse 76 comprend une extrémité 78 de fixation d'un brin conducteur, ainsi qu'une portion tubulaire 80 susceptible de recevoir une tige 50 correspondante. Chaque cosse 76 est en outre pourvue d'une échancrure médiane 82, destinée à être fixée sur un doigt 72 correspondant.Two electrical connection elements 76 are provided, or terminal, each of which is intended to cooperate with an element 46 correspondent. Each terminal 76 has one end 78 fixing a conductive strand, as well as a portion tubular 80 capable of receiving a corresponding rod 50. Each terminal 76 is further provided with a notch median 82, intended to be fixed on a corresponding finger 72.

Il est par ailleurs prévu un organe de protection mécanique 84, qui comprend un corps tubulaire 86 terminé par une collerette 88. Ce corps est muni d'un bossage périphérique externe 90, ainsi que de stries internes d'extrémité 92.A protection body is also provided mechanical 84, which includes a tubular body 86 terminated by a flange 88. This body is provided with a peripheral boss external 90, as well as internal end ridges 92.

Le connecteur 12 comprend également un élément 94 assurant la fixation mutuelle des première et seconde parties 14, 18. Cet élément de fixation 94 est un écrou comprenant une portion taraudée 96 prolongée par des parois tronconiques 98 convergentes, définissant un col d'extrémité 100, de plus faible section transversale. Il est par ailleurs prévu une bague intermédiaire 102 comportant, à une première extrémité, un bourrelet périphérique 104 et, à son extrémité opposée, un chanfrein périphérique 106.The connector 12 also includes an element 94 ensuring the mutual fixing of the first and second parts 14, 18.

There is also a intermediate ring 102 comprising, at a first end, a peripheral bead 104 and, at its opposite end, a peripheral chamfer 106.

La figure 3 illustre une étape intermédiaire du montage du connecteur 12 sur le feu 2, dans laquelle seule la première partie 14 est solidarisée à la paroi 16. Il convient de noter que cette première partie 14 peut être fixée sur la paroi 16, de façon amovible, depuis l'extérieur du feu 2, à savoir selon la flèche F. Ceci garantit une facilité de montage appréciable.Figure 3 illustrates an intermediate stage of assembly of connector 12 on light 2, in which only the first part 14 is secured to the wall 16. It should be noted that this first part 14 can be fixed on the wall 16, removably, from outside the light 2, namely according to arrow F. This guarantees appreciable ease of assembly.

Dans cette configuration, chaque cosse 46 est liée, de façon classique, à un brin électrique correspondant 108, lui-même solidaire d'une cosse supplémentaire 110 destinée à être raccordée à une languette 10 du feu 2.In this configuration, each terminal 46 is linked, conventionally, to a corresponding electrical strand 108, itself secured to an additional terminal 110 intended to be connected to a tab 10 on the light 2.

Chaque branche 52 d'une cosse 46 est fixée axialement contre un rebord 36 correspondant. Par ailleurs, le col 22 est vissé dans l'écrou 42, lui-même logé dans un orifice de la paroi 16 du feu 2.Each branch 52 of a terminal 46 is fixed axially against a corresponding rim 36. Furthermore, the collar 22 is screwed into nut 42, itself housed in an opening in the fire wall 16 2.

En ce qui concerne la deuxième partie 18, dans la configuration intermédiaire précitée, le joint 61 prend appui contre l'épaulement 60. Par ailleurs, la collerette 88 de l'organe de protection 84 prend appui contre le siège 64 de l'élément de raccordement 54. Cette collerette reçoit en outre le bourrelet 104 de la bague 102.Regarding the second part 18, in the above-mentioned intermediate configuration, the seal 61 is supported against the shoulder 60. Furthermore, the flange 88 of the protective member 84 bears against the seat 64 of the connection element 54. This flange also receives the bead 104 of the ring 102.

L'écrou 94 est libre de coulisser le long de la paroi extérieure de l'organe de protection 84. Cependant, son mouvement axial est limité, du fait de la présence du bossage de retenue 90.The nut 94 is free to slide along the wall of the protective device 84. However, its axial movement is limited, due to the presence of the boss restraint 90.

Chaque cosse 76 est fixée sur un doigt 72 correspondant, par coopération de l'échancrure 82 avec le doigt considéré. Elle reçoit, de façon classique, un brin électrique 112 appartenant à un câble conducteur 114. Ces deux brins sont séparés l'un de l'autre par l'intermédiaire de la saillie 70, alors que la gaine 116 de ce câble 114 est entourée partiellement par l'extrémité de l'organe de protection 84.Each terminal 76 is fixed on a corresponding finger 72, by cooperation of the notch 82 with the finger considered. It receives, in a conventional manner, an electrical strand 112 belonging to a conductive cable 114. These two strands are separated from each other by the projection 70, while the sheath 116 of this cable 114 is partially surrounded by the end of the protective member 84.

Le montage complet du connecteur 12 consiste à rapprocher axialement la deuxième partie 18 de la première partie 14. Une fois cette opération effectuée, comme cela est illustrée à la figure 4, les tiges 50 des cosses 46 pénètrent dans les portions tubulaires 80 des cosses 76, ce qui permet la connexion électrique des brins 108 et 112.The complete assembly of the connector 12 consists in bringing together axially the second part 18 of the first part 14. A once this is done, as shown in the Figure 4, the rods 50 of the pods 46 enter the tubular portions 80 of the pods 76, which allows the electrical connection of strands 108 and 112.

La fixation mécanique mutuelle des éléments de raccord 20 et 54 est assurée par coopération de l'écrou 94 avec la partie filetée 30 de l'élément 20. Dans cette configuration, le joint 61 est écrasé entre le siège 32 et l'épaulement 60.The mutual mechanical fixing of the connecting elements 20 and 54 is ensured by cooperation of the nut 94 with the threaded part 30 of element 20. In this configuration, the seal 61 is crushed between the seat 32 and the shoulder 60.

Il est à noter que la bague intermédiaire 102 permet d'éviter tout contact entre l'écrou 94 et l'organe de protection 84. Ceci est avantageux, dans la mesure où un contact entre les deux éléments 84 et 94 précités serait susceptible d'induire une distorsion des brins 112, lors du démontage de cet écrou 94.It should be noted that the intermediate ring 102 allows avoid contact between the nut 94 and the protection 84. This is advantageous, insofar as a contact between the two elements 84 and 94 above would be likely to distort the strands 112, when disassembly of this nut 94.

L'invention n'est pas limitée aux exemples décrits et représentés.The invention is not limited to the examples described and represented.

En effet, il est possible de connecter un conducteur extérieur, analogue à celui 114, pourvu d'un nombre quelconque de brins, en particulier sept, avec un nombre correspondant de brins analogues à ceux 108 logés dans le feu 2.Indeed, it is possible to connect a conductor exterior, similar to that 114, provided with any number of strands, especially seven, with a corresponding number strands similar to those 108 housed in fire 2.

Par ailleurs, il est envisageable de rapporter un adaptateur de diamètre sur le col fileté 22 de l'élément de raccord 20, afin de coopérer avec un orifice de la paroi 16, dont le diamètre serait différent de celui représenté.In addition, it is possible to report a diameter adapter on the threaded neck 22 of the element fitting 20, in order to cooperate with an orifice in the wall 16, whose diameter would be different from that shown.

Il est également possible de relier le câble conducteur 114, à son extrémité opposée à celle représentée sur les figures 3 et 4, avec une autre partie de connecteur, analogue à celle 18. On dispose alors d'un câble, dont les deux extrémités sont susceptibles d'être raccordés sur deux éléments électriques, tels que des feux, ou bien un feu et une boíte de dérivation.It is also possible to connect the conductor cable 114, at its end opposite to that shown in the Figures 3 and 4, with another connector part, similar to that 18. We then have a cable, both of which ends are likely to be connected on two electrical components, such as lights, or a light and junction box.

L'invention permet de réaliser les objectifs précédemment mentionnés.The invention makes it possible to achieve the objectives previously mentioned.

En effet, le connecteur de l'invention assure un raccordement électrique particulièrement aisé pour un utilisateur. Ainsi, il est possible de livrer à ce dernier, d'une part, un certain nombre d'éléments électriques munis de premières parties de connecteur et, d'autre part, d'un certain nombre de câbles conducteurs pourvus, à au moins une de leurs extrémités, d'une seconde partie de connecteur, susceptible de coopérer avec une première partie correspondante. L'utilisateur n'a alors plus qu'à enficher chaque extrémité de câble sur un élément électrique du véhicule routier.Indeed, the connector of the invention provides a particularly easy electrical connection for user. So it is possible to deliver to the latter, on the one hand, a certain number of electrical elements provided with first parts of connector and, on the other hand, some number of conductive cables provided, at least one of their ends, of a second connector part, susceptible to cooperate with a corresponding first party. The user then only has to plug in each end of cable on an electrical element of the road vehicle.

Un tel montage est donc notablement simplifié par l'art antérieur. En effet, selon l'invention, il n'est pas nécessaire pour l'utilisateur de faire passer un conducteur au travers de la paroi de l'élément électrique. Par ailleurs, grâce à l'invention, cet utilisateur a en charge un nombre relativement peu élevé d'éléments, qui sont de manipulation simple.Such mounting is therefore considerably simplified by art prior. Indeed, according to the invention, it is not necessary for the user to pass a conductor to the through the wall of the electrical element. Otherwise, thanks to the invention, this user is responsible for a number relatively low elements, which are manipulative simple.

L'invention est également avantageuse, en ce sens qu'elle permet d'offrir une alternative à l'art antérieur. En effet, le connecteur de l'invention est susceptible d'être monté sur un élément électrique antérieur, puisque la première partie 14 de ce connecteur peut être logé dans un orifice destiné originellement à accueillir un presse-étoupe connu.The invention is also advantageous in that it allows to offer an alternative to the prior art. Indeed, the connector of the invention is capable of being mounted on an earlier electrical element, since the first part 14 of this connector can be housed in an orifice intended originally to accommodate a known cable gland.

L'invention est également avantageuse, en ce sens qu'elle assure une étanchéité très satisfaisante. En faisant notamment à la figure 4, il est à constater qu'il existe quatre niveaux d'étanchéité conférés par le connecteur de l'invention.The invention is also advantageous in that it provides a very satisfactory seal. In particular by in Figure 4, it can be seen that there are four levels sealing imparted by the connector of the invention.

Il s'agit tout d'abord de celui apporté par les stries 92, s'étendant à la périphérie extérieure de la gaine 116 du conducteur 114.It is first of all that brought by the streaks 92, extending at the outer periphery of the sheath 116 of the driver 114.

De plus, le bourrelet 104 de la bague 102 est écrasé, par l'action de l'écrou 94, contre la collerette 88 de l'organe de protection 84.In addition, the bead 104 of the ring 102 is crushed, by the action of the nut 94, against the flange 88 of the member protection 84.

En outre le joint torique 61 garantit un degré supplémentaire d'étanchéité, par son écrasement entre le siège 32 et l'épaulement 60.In addition the O-ring 61 guarantees an additional degree sealing, by its crushing between the seat 32 and shoulder 60.

Enfin, le joint plat 44 assure une étanchéité complémentaire, en étant disposé entre la paroi 16 et l'épaulement 24 de l'élément de raccord 20.Finally, the flat seal 44 provides additional sealing, being disposed between the wall 16 and the shoulder 24 of the connecting element 20.
