Description

Dispositif de connexion électrique amélioré  Improved electrical connection device
La présente invention concerne dispositif de connexion électrique, en particulier un dispositif de connexion électrique utilisé dans un circuit électrique de véhicule automobile. The present invention relates to an electrical connection device, in particular an electrical connection device used in an electric circuit of a motor vehicle.
Un véhicule automobile comporte plusieurs organes électriques qui sont alimentés par une batterie reliée à ceux-ci par des conducteurs électriques, le plus souvent des câbles ou faisceaux de câbles.  A motor vehicle has several electrical components that are powered by a battery connected to them by electrical conductors, usually cables or bundles of cables.
En particulier, il est connu de relier à la batterie du véhicule, d'une part, un alternateur, au moyen d'un conducteur et, d'autre part, un démarreur, au moyen d'une dérivation de ce même conducteur.  In particular, it is known to connect to the battery of the vehicle, on the one hand, an alternator, by means of a conductor and, on the other hand, a starter, by means of a bypass of the same conductor.
Habituellement, le conducteur est un câble électrique comportant une âme en fils torsadés en cuivre ou comprenant essentiellement du cuivre. Une gaine isolante entoure l'âme sur pratiquement toute sa longueur. On dit qu'un élément comprend essentiellement un matériau quand il comprend plus de 50% en masse de ce matériau.  Usually, the conductor is an electrical cable having a twisted wire core of copper or essentially comprising copper. An insulating sheath surrounds the soul over most of its length. An element is said to comprise essentially a material when it comprises more than 50% by mass of this material.
II est connu de réaliser la dérivation évoquée ci-dessus au moyen d'un dispositif de connexion électrique en matériau conducteur électriquement.  It is known to make the derivation mentioned above by means of an electrical connection device of electrically conductive material.
Ce dispositif de connexion électrique comprend, d'une part, une première branche formant cosse de raccordement du démarreur au conducteur et, d'autre part, une seconde branche de liaison destinée à être reliée à l'âme du conducteur.  This electrical connection device comprises, on the one hand, a first branch forming a connecting terminal of the starter to the conductor and, on the other hand, a second connecting branch intended to be connected to the core of the conductor.
Habituellement, le dispositif de connexion électrique est en cuivre ou en matériau comprenant essentiellement du cuivre.  Usually, the electrical connection device is made of copper or material essentially comprising copper.
La gaine du conducteur reliant la batterie à l'alternateur est interrompue de façon à délimiter une partie dénudée de l'âme en cuivre s'étendant entre des première et seconde extrémités d'interruption de la gaine. La branche de liaison (en cuivre) du dispositif de connexion électrique est sertie sur la partie dénudée de l'âme (en cuivre) du conducteur reliant la batterie à l'alternateur. Le cas échéant, ce sertissage est complété par un étamage de la liaison dispositif de connexion électrique/âme du conducteur.  The conductor sheath connecting the battery to the alternator is terminated to delineate a stripped portion of the copper core extending between first and second sheath interruption ends. The connecting branch (copper) of the electrical connection device is crimped on the stripped portion of the core (copper) of the conductor connecting the battery to the alternator. If necessary, this crimping is completed by a tinning of the connection electrical connection device / conductor core.
Néanmoins, afin de réduire le poids et le coût des câbles, on souhaite substituer des câbles à âme en fils torsadés comprenant essentiellement de l'aluminium aux câbles à âme comprenant essentiellement du cuivre.  Nevertheless, in order to reduce the weight and the cost of the cables, it is desired to substitute twisted-core core cables comprising essentially aluminum to core cables comprising essentially copper.
Or, l'aluminium est un matériau qui est peu apte au sertissage, notamment par rapport au cuivre, du fait de ses propriétés mécaniques, particulièrement de sa relaxation mécanique. De plus des couches d'alumine se forment superficiellement sur l'aluminium serti. De ce fait, la liaison entre un conducteur composé de fils en aluminium et un élément formant cosse est de préférence réalisée par soudure. Les procédés de soudure utilisés font appel, selon les applications, à des moyens tels que des moyens de soudure électrique, par friction, ou plus communément par ultrasons. However, aluminum is a material that is poorly suited to crimping, particularly with respect to copper, because of its mechanical properties, particularly its mechanical relaxation. In addition, alumina layers form superficially on crimped aluminum. As a result, the connection between a conductor composed of aluminum wires and a lug element is preferably made by welding. Depending on the application, the welding processes used make use of means such as welding means electric, by friction, or more commonly by ultrasound.
On connaît du document FR 1 356 396 un dispositif de connexion électrique comprenant deux organes de connexion assemblés l'un avec l'autre.  Document FR 1 356 396 discloses an electrical connection device comprising two connecting members assembled together.
Pour relier le dispositif de connexion au conducteur, on coupe ce conducteur de façon à obtenir deux extrémités du conducteur comportant chacune une extrémité d'interruption de l'âme et une extrémité d'interruption de la gaine. Chaque organe de connexion de ce dispositif est relié à une extrémité d'interruption de l'âme correspondante.  To connect the connection device to the conductor, the conductor is cut so as to obtain two ends of the conductor each having an interruption end of the core and an interruption end of the sheath. Each connecting member of this device is connected to an interruption end of the corresponding core.
Les deux organes de connexion comprennent chacun une première branche formant cosse de raccordement et une seconde branche comportant une extrémité sensiblement plane, destinée à être reliée électriquement avec une extrémité d'interruption de l'âme du conducteur correspondante. La première branche de chaque organe de connexion comporte des moyens de liaison avec l'extrémité de la première branche de l'autre organe de connexion, ces moyens de liaison étant préexistants à l'assemblage entre eux des organes de connexion.  The two connecting members each comprise a first branch forming a connecting lug and a second leg having a substantially flat end, intended to be electrically connected to an interruption end of the corresponding conductor core. The first branch of each connection member comprises connecting means with the end of the first branch of the other connection member, these connecting means being pre-existing to the connection between them connecting members.
Ce dispositif de connexion électrique permet de substituer des câbles à âme en fils torsadés comprenant essentiellement de l'aluminium aux câbles à âme comprenant essentiellement du cuivre, mais est relativement complexe à fabriquer.  This electrical connection device makes it possible to substitute twisted core core cables comprising essentially aluminum to core cables comprising essentially copper, but is relatively complex to manufacture.
L'invention a donc pour but de fournir un dispositif de connexion électrique permettant de réaliser une dérivation d'un conducteur à âme comprenant essentiellement de l'aluminium qui soit simple à fabriquer.  The invention therefore aims to provide an electrical connection device for making a branch of a core conductor comprising essentially aluminum which is simple to manufacture.
A cet effet, l'invention a pour objet un dispositif de connexion électrique comprenant un premier organe de connexion comportant :  For this purpose, the subject of the invention is an electrical connection device comprising a first connection member comprising:
- une première branche formant cosse de raccordement, et  a first branch forming a connection terminal, and
- une seconde branche, dite de liaison, destinée à être reliée à l'âme d'un conducteur,  a second branch, referred to as a link, intended to be connected to the core of a conductor,
caractérisé en ce qu'il comprend en outre un second organe de connexion comportant deux extrémités de liaison destinées chacune à être reliée à une extrémité d'interruption de l'âme du conducteur correspondante,  characterized in that it further comprises a second connecting member having two connecting ends each intended to be connected to an interruption end of the corresponding conductor core,
la branche de liaison étant sertie sur une partie intermédiaire du second organe de connexion s'étendant entre les deux extrémités de liaison, si bien que la branche de liaison est reliée à l'âme du conducteur par l'intermédiaire du second organe de connexion.  the connecting branch being crimped on an intermediate portion of the second connecting member extending between the two connecting ends, so that the connecting branch is connected to the core of the conductor through the second connecting member.
Grâce au fait que le premier organe de connexion est relié à l'âme du conducteur par l'intermédiaire d'un second organe de connexion sur lequel est sertie la branche de liaison du premier organe de connexion, il n'est pas nécessaire de prévoir un premier organe de connexion de forme spécifique et/ou complexe pour réaliser la dérivation d'un conducteur à âme comprenant essentiellement de l'aluminium. Due to the fact that the first connecting member is connected to the core of the conductor via a second connecting member on which is crimped the connecting leg of the first connecting member, it is not necessary to provide a first connection member of specific and / or complex shape to achieve the derivation of a core conductor comprising essentially aluminum.
Ainsi, l'on peut par exemple utiliser une cosse standard comme premier organe de connexion pour réaliser une dérivation d'un conducteur dont l'âme serait composée de fils en aluminium. Il suffirait pour cela de sertir cette cosse sur le second organe de connexion dont les extrémités de liaison seraient soudées à l'âme des extrémités d'interruption correspondantes du conducteur.  Thus, it is possible for example to use a standard lug as the first connecting member to make a branch of a conductor whose core is composed of aluminum son. It suffices for this to crimp this lug on the second connecting member whose connecting ends are welded to the core of the corresponding interruption ends of the driver.
Selon un mode de réalisation particulier de l'invention, le second organe de connexion comprend deux éléments de liaison emboîtables, chacun muni d'une extrémité de liaison et d'une extrémité d'emboîtement.  According to a particular embodiment of the invention, the second connection member comprises two interlocking connecting elements, each provided with a connecting end and an interlocking end.
De préférence, pour simplifier le second organe de liaison, les éléments de liaison sont sensiblement identiques.  Preferably, to simplify the second connecting member, the connecting elements are substantially identical.
Pour réaliser un emboîtement simple, l'extrémité d'emboîtement de chaque élément de liaison comprend une partie formant gorge et une partie formant languette, la partie formant gorge étant intercalée entre l'extrémité de liaison et la partie formant languette.  To achieve a simple interlocking, the interlocking end of each connecting element comprises a groove portion and a tongue portion, the groove portion being interposed between the connecting end and the tongue portion.
De préférence, chaque extrémité de liaison du second organe de connexion comprend une partie sensiblement plane munie d'une face de soudage destinée à être soudée sur une extrémité d'interruption de l'âme du conducteur correspondante.  Preferably, each connecting end of the second connection member comprises a substantially planar portion provided with a welding face intended to be welded to an interruption end of the corresponding conductor core.
De préférence, le premier organe de connexion est en matériau comprenant essentiellement du cuivre ou du laiton.  Preferably, the first connection member is made of a material essentially comprising copper or brass.

On a représenté à la figure 1 un circuit électrique 1 , selon l'invention, pour véhicule automobile.  FIG. 1 shows an electric circuit 1 according to the invention for a motor vehicle.
Ce circuit 1 comprend un premier conducteur électrique 2 reliant une batterie 4 d'un véhicule à un alternateur 6 de ce véhicule.  This circuit 1 comprises a first electrical conductor 2 connecting a battery 4 of a vehicle to an alternator 6 of this vehicle.
Le circuit 1 comprend également un démarreur 8 relié également à la batterie 4 par des moyens qui seront décrits plus bas. De façon connue en soi, l'alternateur 6 est entraîné par un moteur thermique du véhicule et le démarreur 8 est destiné à entraîner ce moteur thermique pour le faire démarrer.  The circuit 1 also comprises a starter 8 also connected to the battery 4 by means which will be described below. In a manner known per se, the alternator 6 is driven by a thermal engine of the vehicle and the starter 8 is intended to drive the engine to start it.
Le circuit 1 comprend en outre un dispositif de connexion électrique 10 en matériau conducteur électriquement représenté plus en détail aux figures 2 à 5. Sur la figure 2, on a également représenté une partie du conducteur électrique 2.  The circuit 1 further comprises an electrical connection device 10 made of electrically conductive material, shown in greater detail in FIGS. 2 to 5. FIG. 2 also shows a portion of the electrical conductor 2.
Le dispositif de connexion électrique 10 comprend un premier organe de connexion The electrical connection device 10 comprises a first connection member
12 comportant une première branche formant cosse de raccordement 14 et une seconde branche, dite branche de liaison 16, destinée à être reliée à l'âme du conducteur 2 par l'intermédiaire d'un second organe de connexion 18 comme on le verra plus loin. 12 having a first branch forming connection terminal 14 and a second branch, called connecting branch 16, intended to be connected to the conductor core 2 via a second connection member 18 as will be seen later .
Le circuit 1 comporte également un second conducteur 20 reliant la cosse de raccordement 14 du dispositif de connexion électrique au démarreur 8. Le cas échéant, le démarreur 8 peut être relié directement à la cosse de raccordement 14 du dispositif de connexion électrique 10, sans le second conducteur 20.  The circuit 1 also comprises a second conductor 20 connecting the connecting lug 14 of the electrical connection device to the starter 8. If necessary, the starter 8 can be connected directly to the connection lug 14 of the electrical connection device 10, without the second driver 20.
Ainsi, le dispositif de connexion électrique 10 forme une dérivation depuis le premier conducteur 2 reliant la batterie 4 à l'alternateur 6 vers le démarreur 8 à l'aide du second conducteur 20. Le premier conducteur 2 comporte une âme 21 entourée d'une gaine 22. La gaine 22 est interrompue de façon à délimiter deux extrémités d'interruption de la gaine 24, ainsi que deux extrémités d'interruption de l'âme 25 (visibles à la figure 3) s'étendant entre des première et seconde extrémités d'interruption 24 de la gaine et faisant saillie chacune au-delà de l'extrémité d'interruption 24 correspondante de la gaine. La gaine 22 est réalisée essentiellement, de manière connue en soi, en polymère. Thus, the electrical connection device 10 forms a bypass from the first conductor 2 connecting the battery 4 to the alternator 6 to the starter 8 by means of the second conductor 20. The first conductor 2 comprises a core 21 surrounded by a sheath 22. The sheath 22 is interrupted so as to delimit two interruption ends of the sheath 24, as well as two interruption ends of the core 25 (visible to the 3) extending between first and second interruption ends 24 of the sheath and projecting each beyond the corresponding interruption end 24 of the sheath. The sheath 22 is essentially made, in a manner known per se, of polymer.
Le second conducteur 20 est semblable au premier conducteur 2 mais ne comprend pas de partie dénudée entre deux extrémités d'interruption de gaine. En revanche, de manière classique, le second conducteur 20 comporte deux extrémités dénudées pour permettre le raccordement électrique à respectivement le dispositif de connexion électrique 10 et le démarreur 8.  The second conductor 20 is similar to the first conductor 2 but does not include a stripped portion between two sheath interruption ends. On the other hand, conventionally, the second conductor 20 has two stripped ends to allow electrical connection to the electrical connection device 10 and the starter 8, respectively.
Le second organe de connexion 18 du dispositif de connexion électrique 10 comporte deux extrémités de liaison 26 destinées chacune à être reliées à une extrémité d'interruption de l'âme 25 du conducteur, ainsi que représenté sur les figures 2 et 3.  The second connection member 18 of the electrical connection device 10 comprises two connecting ends 26 each intended to be connected to an interruption end of the conductor core 25, as shown in FIGS. 2 and 3.
La branche de liaison 16 du premier organe de connexion 12 est sertie sur une partie intermédiaire 28 du second organe de connexion 18, comme on peut le voir à la figure 3. Ainsi, la branche de liaison 16 est reliée à l'âme 21 du conducteur 2 par l'intermédiaire du second organe de connexion 18.  The connecting branch 16 of the first connection member 12 is crimped on an intermediate portion 28 of the second connection member 18, as can be seen in FIG. 3. Thus, the connecting branch 16 is connected to the core 21 of the conductor 2 via the second connecting member 18.
Plus particulièrement, dans le mode de réalisation représenté sur les figures, le second organe de connexion 18 comprend deux éléments de liaison 30 emboîtables, chacun muni d'une extrémité de liaison 26 et d'une extrémité d'emboîtement 32. Un de ces éléments de liaison 30 a été représenté sur la figure 4.  More particularly, in the embodiment shown in the figures, the second connection member 18 comprises two interlocking connecting elements 30, each provided with a connecting end 26 and an interlocking end 32. One of these elements link 30 has been shown in FIG.
L'extrémité de liaison 26 de chaque élément de liaison 30 du second organe de connexion 18 comprend une partie sensiblement plane 34 munie d'une face de soudage 36 destinée à être soudée, de préférence par soudage à ultrason, sur une extrémité d'interruption de l'âme 25 du conducteur 2, comme on peut le voir à la figure 3.  The connecting end 26 of each connecting element 30 of the second connection member 18 comprises a substantially planar portion 34 provided with a welding face 36 intended to be welded, preferably by ultrasonic welding, on an interruption end. of the core 25 of the conductor 2, as can be seen in FIG.
L'extrémité d'emboîtement 32 de chaque élément de liaison 30 comprend une partie formant gorge 38 et une partie formant languette 40, la partie formant gorge 38 étant intercalée entre l'extrémité de liaison 30 et la partie formant languette 40.  The interlocking end 32 of each connecting element 30 comprises a groove portion 38 and a tongue portion 40, the groove portion 38 being interposed between the connecting end 30 and the tongue portion 40.
De préférence, les deux éléments de liaison 30 sont sensiblement identiques et sont emboîtés l'un dans l'autre par leurs extrémités d'emboîtement 32.  Preferably, the two connecting elements 30 are substantially identical and are nested one inside the other by their interlocking ends 32.
A cet effet, la partie formant languette 40 de chaque élément de liaison 30 est insérée dans la partie formant gorge 38 de l'autre élément de liaison, comme on peut le voir sur la figure 5.  For this purpose, the tongue portion 40 of each connecting element 30 is inserted into the groove portion 38 of the other connecting element, as can be seen in FIG. 5.
Dans le mode de réalisation présenté sur les figures, les éléments de liaison 30 emboîtés l'un dans l'autre constituent le second organe de connexion 18, dont la partie intermédiaire 28 est formée par les extrémités d'emboîtement 32 ainsi assemblées. Comme on peut le voir sur la figure 3, la branche de liaison 16 du premier organe de connexion 12 est sertie sur cette partie intermédiaire 28, ce qui permet non seulement d'assurer la connexion électrique entre le premier organe de connexion 12 et le second organe de connexion 18, mais aussi de solidariser les deux éléments de liaison 30. In the embodiment shown in the figures, the connecting elements 30 nested one inside the other constitute the second connecting member 18, the intermediate portion 28 is formed by the interlocking ends 32 thus assembled. As can be seen in FIG. 3, the connecting branch 16 of the first connection member 12 is crimped on this intermediate portion 28, which not only makes it possible to provide the electrical connection between the first connection member 12 and the second connecting member 18, but also to secure the two connecting elements 30.
De préférence, le premier organe de connexion 12 est réalisé dans un matériau comprenant essentiellement du cuivre ou du laiton, le second organe de connexion 18 étant en matériau comprenant essentiellement du cuivre, ces matériaux étant bon conducteurs électriques tout en étant aptes au sertissage.  Preferably, the first connecting member 12 is made of a material essentially comprising copper or brass, the second connecting member 18 being made of material comprising essentially copper, these materials being good electrical conductors while being capable of crimping.
Dans le mode de réalisation décrit et représenté sur les figures, le conducteur 2 est en fils torsadés et comprend essentiellement de l'aluminium. Il est alors préférable de protéger la partie dénudée du conducteur 2, à savoir les extrémités d'interruption de l'âme 25, à l'aide de moyens d'étanchéité qui sont représentés à la figure 2.  In the embodiment described and shown in the figures, the conductor 2 is twisted son and essentially comprises aluminum. It is then preferable to protect the stripped portion of the conductor 2, namely the interruption ends of the core 25, by means of sealing means which are shown in FIG.
Comme représenté sur cette figure 2, les moyens d'étanchéité associés à chaque extrémité d'interruption de l'âme 25 comprennent un manchon 42 s'étendant entre une extrémité d'interruption de la gaine 24 du conducteur 2 et une extrémité de liaison 26 du second organe de connexion 18.  As shown in this FIG. 2, the sealing means associated with each interruption end of the core 25 comprise a sleeve 42 extending between an interruption end of the sheath 24 of the conductor 2 and a connecting end 26. of the second connection member 18.
Afin d'assurer une étanchéité maximale, le manchon 42 est agencé de façon à recouvrir cette extrémité de liaison 26 du second organe de connexion 18 et l'extrémité d'interruption de la gaine 24 du conducteur 2.  To ensure a maximum seal, the sleeve 42 is arranged to cover this connecting end 26 of the second connection member 18 and the interruption end of the sheath 24 of the conductor 2.
Les manchons 42 protègent ainsi la partie dénudée de l'âme du conducteur 2 des risques d'oxydation, de la poussière et des liquides. L'aluminium formant essentiellement l'âme 21 du conducteur 2 conserve donc ses excellentes propriétés de conduction électrique.  The sleeves 42 thus protect the stripped portion of the driver's core 2 from the risk of oxidation, dust and liquids. The aluminum essentially forming the core 21 of the conductor 2 thus retains its excellent electrical conduction properties.
Toutefois, l'invention peut s'appliquer à un conducteur 2 ayant une âme comprenant essentiellement du cuivre. Il n'est alors pas nécessaire de protéger la partie dénudée du conducteur 2 à l'aide de moyens d'étanchéité.  However, the invention can be applied to a conductor 2 having a core essentially comprising copper. It is then not necessary to protect the stripped portion of the conductor 2 with sealing means.
L'invention n'est pas limitée au mode de réalisation présenté et d'autres modes de réalisation apparaîtront clairement à l'homme du métier.  The invention is not limited to the embodiment shown and other embodiments will become apparent to those skilled in the art.
Ainsi, on pourra utiliser un second organe de connexion constitué d'une seule pièce et non de deux éléments de liaison, du moment qu'un tel organe soit pourvu de deux extrémités de liaison pouvant être reliées à deux extrémités d'interruption de l'âme du conducteur correspondante.  Thus, it will be possible to use a second connecting member consisting of a single piece and not two connecting elements, as long as such a member is provided with two connecting ends that can be connected to two ends of interruption of the soul of the corresponding driver.
