Connecteur de raccordement  Connection connector
DOMAINE TECHNIQUE TECHNICAL AREA
L'invention est relative à une méthode de raccordement électrique pour deux câbles électriques et de son connecteur de raccordement, plus particulièrement d'une méthode de raccordement et de son connecteur permettant une tenue mécanique des câbles renforcée et un contact électrique des câbles avec le connecteur durable et fiable.  The invention relates to a method of electrical connection for two electrical cables and its connection connector, more particularly a connection method and its connector for mechanical strength of the reinforced cables and electrical contact of the cables with the connector durable and reliable.
ARRIERE-PLAN TECHNOLOGIQUE DE L'INVENTION BACKGROUND OF THE INVENTION
Il est connu depuis déjà quelques années de réduire au maximum le poids des véhicules afin de limiter leur consommation et également leurs émission de particules polluantes. La grande majorité des constructeurs automobiles sont en train de remplacer les faisceaux électriques des véhicules comprenant initialement des brins conducteurs de cuivre, par des faisceaux électriques comprenant des brins en aluminium. Jusqu'alors, avec les faisceaux équipés de brins conducteurs en cuivre, il était possible de réparer toute rupture de câbles par une simple soudure à l'étain des brins sectionnés. Concernant les brins conducteurs en aluminium, la solution de soudure à l'étain n'est plus réalisable. Bien que quelques solutions de réparation de câbles aluminium par sertissage des câbles à l'aide d'outils manuels existent, celle-ci ne conviennent nullement aux réparations de faisceaux électriques embarqués dans des véhicules. L'accès aux câbles ainsi que la fiabilité recherchée ne permettent pas raisonnablement d'envisager les solutions existantes.  It has been known for a few years to reduce the weight of vehicles as much as possible in order to limit their consumption and also their emission of polluting particles. The vast majority of car manufacturers are replacing the electrical harnesses of vehicles initially comprising copper conductor strands, with electrical harnesses comprising aluminum strands. Until then, with the bundles equipped with copper conductive strands, it was possible to repair any breakage of cables by a simple tin soldering of the severed strands. For aluminum conductive strands, the tin solder solution is no longer feasible. Although some solutions for repairing aluminum cables by crimping cables using hand tools exist, it is not suitable for repairs of electrical harnesses embedded in vehicles. Access to the cables as well as the reliability sought do not reasonably allow to consider the existing solutions.
La présente invention vise à proposer une solution nouvelle permettant de résoudre ces problèmes de façon économique, aisée et fiable.  The present invention aims to propose a new solution to solve these problems economically, easily and reliably.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
Selon la figure 1, un connecteur de raccordement électrique 10 et deux câbles 12, 14 non montés dans le connecteur 10 sont représentés. Les deux câbles 12, 14 et le connecteur 10 forme un ensemble de raccordement 42.  According to Figure 1, an electrical connection connector 10 and two cables 12, 14 not mounted in the connector 10 are shown. The two cables 12, 14 and the connector 10 form a connection assembly 42.
Chaque câble électrique 12, 14 comprend une partie isolée par un isolant pouvant être une gaine isolante 16 en caoutchouc ou en plastique souple. Chaque câble électrique comprend également une extrémité dénudée 18. L'extrémité dénudée 18 comprend une partie dénudée adjacente 39 à la gaine isolante 16 et une extrémité libre dénudée 40. Selon le mode de réalisation représenté, la partie dénudée 18 est constituée de multiples brins 20 conducteurs. De préférence, ces brins conducteurs 20 sont des brins en aluminium. Each electrical cable 12, 14 comprises a part insulated by an insulation which may be an insulating sheath 16 of rubber or of flexible plastic. Each electrical cable also comprises a stripped end 18. The stripped end 18 comprises an adjacent stripped portion 39 to the insulating sheath 16 and a stripped free end 40. According to the embodiment shown, the part stripped 18 consists of multiple strands 20 conductors. Preferably, these conductive strands 20 are aluminum strands.
Le connecteur 10 comporte un corps creux 11 de forme globalement cylindrique. Le connecteur 10 est conducteur électriquement, de préférence en cuivre. Tel que représenté, le corps 11 est de forme cylindrique de base rectangulaire. Le corps 10 s'étend selon l'axe longitudinal L et comprend à chaque extrémité axiale une ouverture 22 par laquelle la partie dénudée 18 des câbles peut être introduite.  The connector 10 comprises a hollow body 11 of generally cylindrical shape. The connector 10 is electrically conductive, preferably copper. As shown, the body 11 is of cylindrical shape of rectangular base. The body 10 extends along the longitudinal axis L and comprises at each axial end an opening 22 through which the stripped portion 18 of the cables can be introduced.
Le connecteur de raccordement 10 comprend sur une surface 13 du corps 11 des moyens de compressions 31, 33 des extrémités dénudées 18 des câbles électriques comportant quatre organes de compression 24, 26, 28, 30. Les quatre organes de compression 24, 26, 28, 30 sont agencés à travers la surface 13 du corps 11 du connecteur de raccordement 10. Plus précisément, chaque organe de compression 24, 26, 28, 30 comprend une partie cylindrique s'étendant transversalement à travers le corps 11 du connecteur de raccordement 10.  The connection connector 10 comprises, on a surface 13 of the body 11, compression means 31, 33 of the stripped ends 18 of the electrical cables comprising four compression members 24, 26, 28, 30. The four compression members 24, 26, 28 , 30 are arranged through the surface 13 of the body 11 of the connection connector 10. More specifically, each compression member 24, 26, 28, 30 comprises a cylindrical portion extending transversely through the body 11 of the connection connector 10 .
Les quatre organes de compression 24, 26, 28, 30 sont agencés longitudinalement les uns après les autres depuis les ouvertures 22 du corps 1 1 du connecteur 10. Les quatre organes de compression 24, 26, 28, 30 sont agencés alignés longitudinalement et de préférence répartie substantiellement équidistant les uns des autres. Chaque organe de compression 24, 26, 28, 30 est muni d'un organe d'ajustement 32, 34, 36, 38 de la compression des extrémités dénudées 18. Les organes de compression 24, 26, 28, 30 représentés, sont des vis de serrages dont la tête de vis permet d'ajuster la compression sur la partie dénudée 18 des câbles électriques 12, 14.  The four compression members 24, 26, 28, 30 are arranged longitudinally one after the other from the openings 22 of the body 1 1 of the connector 10. The four compression members 24, 26, 28, 30 are arranged longitudinally aligned and distributed preference substantially equidistant from each other. Each compression member 24, 26, 28, 30 is provided with an adjustment member 32, 34, 36, 38 for compressing the stripped ends 18. The compression members 24, 26, 28, 30 shown are tightening screws whose screw head makes it possible to adjust the compression on the stripped portion 18 of the electric cables 12, 14.
Une méthode de raccordement électrique des deux câbles électriques 12, A method of electrical connection of the two electric cables 12,
14 comprend donc comme première étape, l'insertion des parties dénudées 18 des deux câbles 12, 14 dans le corps 11 du connecteur 10 par chacune des ouvertures 22. 14 thus comprises as a first step the insertion of the stripped portions 18 of the two cables 12, 14 into the body 11 of the connector 10 by each of the openings 22.
Selon la figure 2, une seconde étape consiste à insérer les deux parties dénudées 18 dans le corps 11 du connecteur 10 jusqu'à ce que les brins 20 ne deviennent quasiment plus visibles, en d'autres termes, jusqu'à ce que chaque gaine isolante 16 de chaque câble électrique 12, 14 vienne obturer les ouvertures 22. Plus précisément, selon la figure 3, les quatre organes de compression 24, 26, 28, 30 sont agencés en vis à vis d'une paroi de fond 15 du corps 11 du connecteur de raccordement 10. Cette paroi 15 est la surface intérieure du corps 11 du connecteur 10 en vis-à-vis des organes de compression 24, 26, 28, 30. Cette paroi de fond 15 défini un passage de câbles 17, plus particulièrement un passage pour la partie dénudée 18 des câbles électriques 12, 14. According to Figure 2, a second step is to insert the two stripped portions 18 in the body 11 of the connector 10 until the strands 20 become almost more visible, in other words, until each sheath insulating 16 of each electric cable 12, 14 comes to close the openings 22. More precisely, according to FIG. 3, the four compression members 24, 26, 28, 30 are arranged opposite a bottom wall 15 of the body 11 of the connection connector 10. This wall 15 is the internal surface of the 11 of the connector body 10 vis-a-vis the compression members 24, 26, 28, 30. This bottom wall 15 defines a cable passage 17, more particularly a passage for the stripped portion 18 of the electric cables 12, 14 .
Les quatre organes de compression 24, 26, 28, 30 se répartissent en un premier moyen de compression 31 comprenant les deux premiers organes de compression 24, 30 agencés directement adjacent aux ouvertures 22 du corps 11 du connecteur 10 et permettant le maintien des extrémités dénudées 18 des câbles électriques 12, 14 dans le corps 11 connecteur 10. Les quatre organes de compression 24, 26, 28, 30 se répartissent également en un second moyen de compression 33 comprenant deux seconds organes de compression 26, 28 agencés longitudinalement avec les premiers organes de compression 24, 30 et permettants de comprimer les extrémités libres dénudées 40 des câbles électriques 12, 14. Les deux seconds organes de compression 26, 28 sont donc agencés entre les deux premiers organes de compression 24, 30. Les deux seconds organes de compressions 26, 28 permettent d'assurer le contact électrique entre le connecteur de raccordement 10 et les câbles électriques 12, 14.  The four compression members 24, 26, 28, 30 are distributed in a first compression means 31 comprising the first two compression members 24, 30 arranged directly adjacent to the openings 22 of the body 11 of the connector 10 and allowing the stripped ends to be held. 18 of the electrical cables 12, 14 in the body 11 connector 10. The four compression members 24, 26, 28, 30 are also distributed in a second compression means 33 comprising two second compression members 26, 28 arranged longitudinally with the first compression members 24, 30 and making it possible to compress the stripped free ends 40 of the electric cables 12, 14. The two second compression members 26, 28 are therefore arranged between the first two compression members 24, 30. compressions 26, 28 make it possible to ensure electrical contact between the connection connector 10 and the electric cables 12, 14.
Chaque organe de compression 24, 26, 28, 30 comprend à son extrémité située dans le corps creux 11 du connecteur 10, une plaque de compression 19, 21, 23 agencée perpendiculairement à l'organe de compression 26 et s'étendant longitudinalement les unes vers les autres. Chaque plaque de compression 19, 21, 23 comprend une partie plane 25 prévue pour comprimer les extrémités dénudées 18 des câbles électriques 12, 14. Lors de l'actionnement de chaque organe de compression 24, 26, 28, 30, chaque plaque de compression 19, 21, 23 s'enfonce en direction de la paroi de fond 15 du passage de câble 17, les plaques de compression 19, 21, 23 n'effectuant aucun mouvement de rotation. L'homme du métier comprendra que l'agencement des plaques de compression 19, 21, 23 à l'extrémité des organes de compression 24, 26, 28, 30, est réalisé de sorte que l'actionnement par rotation des organes de compression 24, 26, 28, 30 n'entraine aucun mouvement de rotation des plaques de compression 19, 21 , 23.  Each compression member 24, 26, 28, 30 comprises at its end located in the hollow body 11 of the connector 10, a compression plate 19, 21, 23 arranged perpendicularly to the compression member 26 and extending longitudinally. to others. Each compression plate 19, 21, 23 comprises a planar part 25 designed to compress the stripped ends 18 of the electric cables 12, 14. Upon actuation of each compression member 24, 26, 28, 30, each compression plate 19, 21, 23 is sinking towards the bottom wall 15 of the cable passage 17, the compression plates 19, 21, 23 performing no rotational movement. Those skilled in the art will understand that the arrangement of the compression plates 19, 21, 23 at the end of the compression members 24, 26, 28, 30 is made so that the actuation by rotation of the compression members 24 , 26, 28, 30 causes no rotational movement of the compression plates 19, 21, 23.
Les parties dénudées 18 des câbles électriques 12, 14 sont agencées dans le passage de câble 17 du corps 1 1 du connecteur 10. La partie dénudée adjacente 39 à la gaine isolante 16 de chaque câble est positionnée en regard de chacun des deux premiers organes de compression 24, 30. Chaque extrémité libre dénudée 40 des câbles 12, 14 est agencée en regard de chaque second organe de compression 26, 28. Les parties dénudées 18 des deux câbles électriques 12, 14 ne sont pas contact les unes avec les autres. Le passage de câble 17 est suffisamment dimensionné pour permettre aux parties dénudées 18 d'y être insérer sans être en contact avec les plaques de compression 19, 21, 23 des organes de compression 24, 26, 28, 30. The stripped parts 18 of the electric cables 12, 14 are arranged in the cable passage 17 of the body 1 1 of the connector 10. The adjacent stripped portion 39 to the insulating sheath 16 of each cable is positioned opposite each of the first two compression members 24, 30. Each free stripped end 40 of the cables 12 , 14 is arranged facing each second compression member 26, 28. The stripped portions 18 of the two electrical cables 12, 14 are not in contact with each other. The cable passage 17 is sufficiently sized to allow the stripped portions 18 to be inserted without being in contact with the compression plates 19, 21, 23 of the compression members 24, 26, 28, 30.
Selon la figure 3 et selon la figure 4, les plaques 21, 23 des seconds organes de compression 26, 28 comprennent également une spatule 27, 29 agencée longitudinalement en continuité avec la partie plane 25 et relevée transversalement vers la surface 13 du corps traversée par les seconds organes de compression 26, 28. La spatule 27, 29 de chacun des deux seconds organes de compression 26, 28 est orientée respectivement en direction de chacun des deux premiers organes de compression 24, 30 lui étant directement adjacent.  According to Figure 3 and according to Figure 4, the plates 21, 23 of the second compression members 26, 28 also comprise a spatula 27, 29 arranged longitudinally in continuity with the flat portion 25 and raised transversely to the surface 13 of the body traversed by the second compression members 26, 28. The spatula 27, 29 of each of the two second compression members 26, 28 is oriented respectively towards each of the first two compression members 24, 30 being directly adjacent thereto.
Selon la figure 5, une troisième étape consiste à ajuster les organes de compression 24, 26, 28, 30 sur les parties dénudées 18 des câbles électriques. De préférence les organes de compression 24, 26, 28, 30 s'enfoncent à travers le corps 11 du connecteur de raccordement 10 par une action de vissage de l'organe d'ajustement 32, 34, 36, 38. Lorsque l'organe de compression 24 s'enfonce dans le corps 11 du connecteur 10, il comprime la partie dénudée 18 du câble électrique 12, 14.  According to Figure 5, a third step is to adjust the compression members 24, 26, 28, 30 on the stripped portions 18 of the electric cables. Preferably, the compression members 24, 26, 28, 30 extend through the body 11 of the connection connector 10 by a screwing action of the adjustment member 32, 34, 36, 38. 24 compression sinks into the body 11 of the connector 10, it compresses the stripped portion 18 of the electric cable 12, 14.
Les quatre organes de compression 24, 26, 28, 30 compriment les parties dénudées 18 des deux câbles électriques 12, 14 contre la paroi de fond 15 du passage de câble 17. La compression des extrémités libres 40 des câbles 12, 14 exercée par les deux seconds organes de compression 26, 28 est bien plus importante que la compression des extrémités dénudées 39 adjacentes à chaque gaine isolante 16 exercée par les deux premiers organes de compression 24, 30. De façon générale, pour des câbles aluminium de section comprise entre 0.30 mm2 et 6 mm2, les sections dénudées adjacentes 39 aux gaines isolantes sont comprimées de sorte à réduire la section de 15% à 40% de leur section initiale afin d'assurer un maintien mécanique dans le connecteur de raccordement 10. Egalement, de façon générale, pour des câbles aluminium de section comprise entre 0.30 mm2 et 6 mm2, les sections d'extrémités libres dénudées 40 sont comprimées de sorte à réduire leur section de 45% à 65% de leur section initiale afin d'assurer un contact électrique entre le câble 12, 14 et le connecteur de raccordement 10. De préférence, afin de garantir une fiabilité dans le temps du raccordement électrique compatible avec l'environnement automobile, il est préférable que la compression exercée par les deux premiers organes de compression 24, 30 entraine une réduction de la section de la partie dénudée du câble 18 adjacente à la gaine isolante 16 entre 20% à 30% alors que la compression exercée par les deux seconds organes de compression 26, 28 entraine une réduction de la section des extrémités libres dénudées 40 du câble 12, 14 entre 50% à 60% de sa section initiale non comprimée. The four compression members 24, 26, 28, 30 compress the stripped portions 18 of the two electrical cables 12, 14 against the bottom wall 15 of the cable passage 17. The compression of the free ends 40 of the cables 12, 14 exerted by the two second compression members 26, 28 is much larger than the compression of the stripped ends 39 adjacent to each insulating sheath 16 exerted by the first two compression members 24, 30. In general, for aluminum cables of section between 0.30 mm 2 and 6 mm 2 , the adjacent stripped sections 39 to the insulating sheaths are compressed so as to reduce the section by 15% to 40% of their initial section in order to ensure mechanical retention in the connection connector 10. Also, generally, for aluminum cables having a cross-section of between 0.30 mm 2 and 6 mm 2 , the bare free end sections 40 are compressed so as to reduce their section from 45% to 65% of their initial section in order to ensure electrical contact between the cable 12, 14 and the connection connector 10. Preferably, in order to guarantee a reliability in time of the electrical connection compatible with the automotive environment, it is preferable that the compression exerted by the first two compression members 24, 30 causes a reduction in the section of the stripped portion of the cable 18 adjacent to the insulating sheath 16 between 20% to 30% while the compression exerted by the two second compression members 26, 28 causes a reduction of the section of the stripped free ends 40 of the cable 12, 14 between 50% to 60% of its uncompressed initial section.
On comprend, notamment selon les figures 6 et 7 que la définition de la section de la partie dénudée du câble 18 est l'épaisseur suivant l'axe transversal T de la partie dénudée du câble. La section de la partie dénudée du câble 18 lorsqu'elle n'est pas comprimée, définie donc sa section initiale SI . Lorsque la partie dénudée du câble 18 est comprimée par les organes de compression 24, 26, sa section diminue par exemple de sa section initiale SI jusqu'à une section S2 ou S3 plus faible que sa section initiale. Chaque organe de compression 24, 26, 28, 30 permet donc une réduction de section de la partie dénudée du câble 18 selon un rapport exprimé en pourcentage de réduction de la section initiale S 1.  It is understood, in particular according to Figures 6 and 7 that the definition of the section of the stripped portion of the cable 18 is the thickness along the transverse axis T of the stripped portion of the cable. The section of the stripped part of the cable 18 when it is not compressed, therefore defines its initial section SI. When the stripped portion of the cable 18 is compressed by the compression members 24, 26, its section decreases for example from its initial section SI to a section S2 or S3 lower than its initial section. Each compression member 24, 26, 28, 30 therefore allows a section reduction of the stripped portion of the cable 18 in a ratio expressed as a reduction percentage of the initial section S 1.
Dans le mode de réalisation représenté à la figure 5, il est à noter que les plaques de compression 21, 23 des seconds organes de compression 26, 28 sont agencées suffisamment proche des plaques de compression 19 des premiers organes de compression 24, 30 de sorte que la différence de compression entraine l'apparition d'une zone de transition 44 (plus visible sur la figure 7) en pente descendante de la partie dénudée 39 adjacente aux gaines isolantes 16 vers les extrémités libres dénudées 40. Les spatules 27, 29 de chacun des seconds organes de compression 24, 28 sont alors en appui sur les deux zones de transition 44.  In the embodiment shown in Figure 5, it should be noted that the compression plates 21, 23 of the second compression members 26, 28 are arranged sufficiently close to the compression plates 19 of the first compression members 24, 30 so that the difference in compression causes the appearance of a transition zone 44 (more visible in FIG. 7) on a downward slope of the stripped portion 39 adjacent to the insulating sheaths 16 towards the stripped free ends 40. The spatulas 27, 29 of each of the second compression members 24, 28 are then supported on the two transition zones 44.
Chaque spatule 27, 29 permet plus particulièrement aux seconds organes de compression 26, 28 d'éviter un endommagement des brins conducteurs 20 dans les zones de transition. Chaque spatule 27, 29 vient reposer sur une zone de transition 44 et évite un contact direct des brins 20 du câble 12, 14 avec une tranche saillante de la partie plane 25 de la plaque de compression 21, 23. Each spatula 27, 29 more particularly allows the second compression members 26, 28 to prevent damage to the conductive strands 20 in the transition zones. Each spatula 27, 29 comes to rest on a transition zone 44 and avoids a direct contact of the strands 20 of the cable 12, 14 with a protruding slice of the flat portion 25 of the compression plate 21, 23.
La troisième étape consiste donc plus particulièrement à ajuster la compression des premiers et des seconds organes de compression 24, 26, 28, 30 sur les parties dénudées 18 des câbles électrique de sorte à maintenir les câbles 12, 14 et à assurer également un contact électrique. Par conséquent, les deux premiers organes de compression 24, 30 sont bien moins enfoncés au travers du corps 11 du connecteur 10 que les deux seconds organes de compression 26, 28. La compression assurant le maintien des extrémités dénudées 18 câbles électriques 12, 14 dans le corps 11 du connecteur 10 doit être suffisante pour le maintien mais pas trop élevée afin d'éviter une détérioration de la partie dénudée 18 des câbles et donc une fragilité de ceux-ci. Les deux seconds organes de compression 26, 28 sont bien plus enfoncés au travers du corps 11 du connecteur 10 que les deux premiers organes de compression 24, 30 de sorte à garantir une compression suffisante des parties dénudées 18 des câbles 12, 14, garantissant ainsi un bon contact électrique entre les parties dénudées 18 des câbles 12, 14 et le connecteur de raccordement 10.  The third step is therefore more particularly to adjust the compression of the first and second compression members 24, 26, 28, 30 on the stripped portions 18 of the electric cables so as to maintain the cables 12, 14 and also to make electrical contact . Therefore, the first two compression members 24, 30 are much less penetrated through the body 11 of the connector 10 than the two second compression members 26, 28. The compression ensuring the maintenance of the stripped ends 18 electric cables 12, 14 in the body 11 of the connector 10 must be sufficient for the maintenance but not too high to avoid damage to the stripped portion 18 of the cables and therefore a fragility thereof. The two second compression members 26, 28 are further sunk through the body 11 of the connector 10 than the first two compression members 24, 30 so as to ensure sufficient compression of the stripped portions 18 of the cables 12, 14, thus ensuring a good electrical contact between the stripped portions 18 of the cables 12, 14 and the connection connector 10.
Selon la figure 8, les quatre organes de compression 24, 26, 28, 30 sont sectionnés. Une quatrième étape consiste à comprimer les parties dénudées 18 des câbles 12, 14 jusqu'à ce que les organes d'ajustement 32, 34, 36, 38 ne permettent plus une compression supérieure à celle déjà exercée. Selon le mode de réalisation représentée, la tête de vis de chaque organe de compression 24, 26, 28, 30 s'est brisée de sorte à autolimiter la compression sur la partie dénudée 18 des câbles. A titre d'exemple, les deux premiers organes d'ajustement 32, 38 se sont brisés pour un couple de serrage de la tête de vis de 2 Newton/mètre correspondant à une compression de la section de la partie dénudée 18 du câble de 20%. Les deux seconds organes d'ajustement 34, 36 se sont brisés pour un couple de serrage de la tête de vis de 6 Newton/mètre correspondant à une compression de la section de la partie dénudée 18 du câble de 60%.  According to Figure 8, the four compression members 24, 26, 28, 30 are sectioned. A fourth step is to compress the stripped portions 18 of the cables 12, 14 until the adjustment members 32, 34, 36, 38 no longer allow compression greater than that already exerted. According to the embodiment shown, the screw head of each compression member 24, 26, 28, 30 has broken so as to self-compress the compression on the stripped portion 18 of the cables. By way of example, the first two adjustment members 32, 38 have broken down for a tightening torque of the screw head of 2 Newton / meter corresponding to a compression of the section of the stripped portion 18 of the cable 20 %. The two second adjustment members 34, 36 have broken for a tightening torque of the screw head of 6 Newton / meter corresponding to a compression of the section of the stripped portion 18 of the 60% cable.
Il est à noter que les organes d'ajustements 32, 34, 36, 38, à savoir les têtes de vis, ne sont plus représentés, car ils ont étés brisés par le couple de serrage appliqué afin d'obtenir la profondeur de compression voulue sur les parties dénudées 18 des câbles 12, 14. En d'autres termes, chaque moyen de compression 31 , 33 comprenant chacun un organe de compression 24, 26, 28, 30, un plaque de compression 19, 21, 23 et un organe d'ajustement 32, 34, 36, 38, s'est autolimité lorsqu'il est arrivé à un point de rupture de son organe d'ajustement 32, 34, 36, 38 dû à un couple de serrage allant au-delà de sa limite physique. Le choix des premiers et des seconds moyens de compression 31, 33 est donc un choix directement lié par la compression maximale voulue sur les parties dénudées 18 des câbles 12, 14. It should be noted that the adjustment members 32, 34, 36, 38, namely the screw heads, are no longer shown because they have been broken by the applied torque in order to obtain the desired depth of compression. on the stripped portions 18 of the cables 12, 14. In other words, each compression means 31, 33 each comprising a compression member 24, 26, 28, 30, a compression 19, 21, 23 and an adjustment member 32, 34, 36, 38, has self-limited when it has reached a breaking point of its adjustment member 32, 34, 36, 38 due to a tightening torque beyond its physical limit. The choice of the first and second compression means 31, 33 is therefore a choice directly linked by the desired maximum compression on the stripped portions 18 of the cables 12, 14.
Selon la figure 9, une alternative au mode de réalisation à quatre organes de compression est illustrée. Dans ce mode de réalisation, le premier moyen de compression 31 comporte toujours deux premiers organes de compression 24, 30 agencés adjacents aux ouvertures 22 du corps 11 du connecteur de raccordement 10. Le second moyen de compression comprend un seul second organe de compression 46. L'agencement des extrémités libres des câbles 40 est cette fois ci un agencement en superposition. Seules les extrémités libres 40 sont superposées entre elles de sorte qu'un seul second organe de compression 46 est nécessaire pour comprimer les deux extrémités libres dénudées 40. Dans ce mode de réalisation, la partie dénudée adjacente 39 à la gaine isolante 16 du câble 12 dont l'extrémité dénudée 40 est superposée, repose sur une partie surélevée 48 selon l'axe transversal de la paroi de fond 15 du corps 11 du connecteur 10. La paroi de fond 15 a donc une forme en escalier à une marche, la marche formant butée pour la partie dénudée 18 du câble 14 se situant sous la partie dénudée 18 de l'autre câble 12. La partie surélevée 48 sur laquelle repose la partie dénudée 39 adjacente à la gaine isolante 16 du câble 12 superposée, permet de positionner longitudinalement l'extrémité dénudée 18 du câble 12 superposée sur l'autre extrémité dénudée 18 de l'autre câble 14. La partie surélevée 48 est donc la partie de la paroi de fond 15 en vis-à-vis d'un des premiers organes de compression 24, l'autre partie de la paroi de fond 15 étant en vis-à-vis de l'autre premier organe de compression 30 et du second organe de compression 46, la marche étant globalement agencée descendante en vis-à-vis de l'espace entre ledit un des premiers organes de compression 24 et le second organe de compression 46.  According to FIG. 9, an alternative to the embodiment with four compression members is illustrated. In this embodiment, the first compression means 31 always comprises two first compression members 24, 30 arranged adjacent the openings 22 of the body 11 of the connection connector 10. The second compression means comprises a single second compression member 46. The arrangement of the free ends of the cables 40 is this time an arrangement in superposition. Only the free ends 40 are superimposed on each other so that only one second compression member 46 is necessary to compress the two bare free ends 40. In this embodiment, the adjacent stripped portion 39 to the insulating sheath 16 of the cable 12 whose stripped end 40 is superimposed, rests on an elevated portion 48 along the transverse axis of the bottom wall 15 of the body 11 of the connector 10. The bottom wall 15 therefore has a step-like shape at a step, the step forming a stop for the stripped portion 18 of the cable 14 located under the stripped portion 18 of the other cable 12. The raised portion 48 which rests the stripped portion 39 adjacent to the insulating sheath 16 of the superimposed cable 12, makes it possible to position longitudinally the stripped end 18 of the cable 12 superimposed on the other stripped end 18 of the other cable 14. The raised portion 48 is therefore the portion of the bottom wall 15 vis-à-vis one of the first compression members 24, the other part of the bottom wall 15 facing the other first compression member 30 and the second compression member 46, the step being generally arranged downwardly opposite the space between said one of the first compression members 24 and the second compression member 46.
Ce mode de réalisation présente l'avantage de n'avoir que trois organes de compression 24, 30, 46. De préférence, chaque taux de compression des parties dénudées 18 des deux câbles 12, 14 peut rester identique au mode de réalisation à quatre organes de compression, à savoir, de préférence : les deux premiers organes de compression 24, 30 entraine une réduction de 20% à 30%> de la section initiale de la partie dénudée, le second organe de compression 46 entraine une réduction de 50%> à 60%> de la section initiale de chacune des deux extrémités dénudées 18 des deux câbles 12, 14. This embodiment has the advantage of having only three compression members 24, 30, 46. Preferably, each compression ratio of the stripped portions 18 of the two cables 12, 14 can remain identical to the four-member embodiment. compression, namely, preferably: the first two compression members 24, 30 causes a reduction of 20% to 30%> of the initial section of the stripped portion, the second compression member 46 causes a reduction of 50%> to 60%> of the initial section of each of the two bare ends 18 of the two cables 12, 14.
Selon la figure 10, une autre alternative aux modes de réalisation est représentée. On notera que seule la moitié d'une coupe transversale d'un connecteur de raccordement 10 a été représentée. Dans ce mode de réalisation, l'extrémité dénudée 18 d'un câble électrique 12 est comprimée par trois organes de compression 48, 50, 52. Telle que dans le mode de réalisation à quatre organes de compression, un premier organe de compression 48 est agencé adjacent à l'ouverture 22 et un second organe de compression 52 est agencé de sorte à comprimée l'extrémité libre 40 dénudée du câble 12. Cette alternative comprend un troisième organe de compression 50 agencé entre le premier et le second organe de compression 48, 52. Le premier et le second organe de compression 48, 52 compriment de la même manière que le mode de réalisation de la figure 8 les parties dénudées 18 des câbles électriques 12, 14. Le troisième organe de compression 50, comporte également une plaque de compression 19. Le troisième organe de compression 50 comprime également la partie dénudée 18 du câble électrique 12, mais avec une force de compression plus faible que le second organe de compression 52 et plus forte que le premier organe de compression 48. De préférence, il comprime la partie dénudée 18 avec une force de l'ordre de la moyenne arithmétique des deux autres organes de compression 48, 52. Par exemple, en pratique, cela peut se traduire par une compression par le premier organe de compression 48 réduisant la section de la partie dénudée 18 de 20%> à 30%), le troisième organe de compression 50 réduisant la section de 35% à 45%, le second organe de compression 52 réduisant la section de l'extrémité libre de 50%> à 60%). Cette alternative présente l'avantage de réduire la pente des zones de transition 44 et donc de pouvoir utiliser des plaques de compression 19 sans spatules 27, 29.  According to Fig. 10, another alternative to the embodiments is shown. Note that only half of a cross section of a connector 10 has been shown. In this embodiment, the stripped end 18 of an electric cable 12 is compressed by three compression members 48, 50, 52. As in the embodiment with four compression members, a first compression member 48 is arranged adjacent the opening 22 and a second compression member 52 is arranged so as to compress the free end 40 stripped of the cable 12. This alternative comprises a third compression member 50 arranged between the first and the second compression member 48 , 52. The first and second compression members 48, 52 similarly compress the embodiment of FIG. 8 to the stripped portions 18 of the electric cables 12, 14. The third compression member 50 also comprises a plate The third compression member 50 also compresses the stripped portion 18 of the electric cable 12, but with a lower compressive force than the second compression member. It compresses the stripped portion 18 with a force of the order of the arithmetic average of the two other compression members 48, 52. For example, in practice, this may result in compression by the first compression member 48 reducing the section of the stripped portion 18 by 20%> to 30%), the third compression member 50 reducing the section from 35% to 45%, the second member compression 52 reducing the free end section by 50%> to 60%). This alternative has the advantage of reducing the slope of the transition zones 44 and therefore of being able to use compression plates 19 without spatulas 27, 29.
L'invention ne se limite pas aux modes de réalisation représentés. The invention is not limited to the embodiments shown.
Alternativement, le corps 11 du connecteur 10 peut être de forme différente comme par exemple de forme cylindrique à base circulaire. Egalement, le nombre d'organes de compression 24, 26, 28, 30 par extrémités dénudées 18 des câbles électriques 12, 14 peut être supérieur à trois. Le nombre d'organe de compression 24, 26, 28, 30 pour l'extrémité dénudée 18 d'un câble 12 peut être différent du nombre d'organes de compression 24, 26, 28de l'extrémité dénudée 18 de l'autre câble 14. L'invention peut également s'étendre aux connecteurs de raccordement 10 de plus de deux câbles 12, 14. Alternatively, the body 11 of the connector 10 may be of different shape, for example of cylindrical shape with a circular base. Also, the number of compression members 24, 26, 28, 30 by stripped ends 18 of the cables 12, 14 may be greater than three. The number of compression members 24, 26, 28, 30 for the stripped end 18 of a cable 12 may be different from the number of compression members 24, 26, 28 of the stripped end 18 of the other cable 14. The invention can also extend to the connection connectors 10 of more than two cables 12, 14.
