Description

L'invention concerne le domaine de la connectique, et notamment celui de la connectique automobile. En particulier, l'invention concerne un ensemble de connexion, des bornes femelle et mâle et un procédé de montage d'une borne femelle, pour un usage en connectique de puissance.The invention relates to the field of connectors, and in particular that of automotive connectors. In particular, the invention relates to a connection assembly, female and male terminals and a method of mounting a female terminal, for use in power connectors.

Dans le domaine des véhicules automobiles et notamment des véhicules électriques, hybrides ou hybrides rechargeables, les courants forts peuvent être transmis dans des réseaux de câblage et/ou des circuits électriques de puissance, tels que ceux interconnectant entre eux, des éléments tels qu'une batterie, un moteur, un convertisseur de tension, etc. De même, même si les courants ne sont pas nécessairement de très forte intensité, les tensions enjeux peuvent être relativement élevées et notamment supérieures à 60 Volts.In the field of motor vehicles and in particular electric, hybrid or plug-in hybrid vehicles, strong currents can be transmitted in wiring networks and / or electrical power circuits, such as those interconnecting with each other, elements such as a battery, motor, voltage converter, etc. Likewise, even if the currents are not necessarily very strong, the voltages at stake can be relatively high and in particular greater than 60 volts.

Lorsque qu'il est nécessaire d'intégrer des connecteurs dans les réseaux de câblage destinés à transmettre des courants, ces connecteurs doivent être munis de bornes de tailles et de section suffisamment importantes pour transmettre ces courants forts sans échauffement excessif. Ainsi, par exemple, on peut être amené à utiliser des bornes mâles dont la section peut atteindre 113mm2 ou davantage. De même les bornes femelles doivent pouvoir recevoir des bornes mâles présentant de telles sections et être protégées, notamment lorsqu'elles sont utilisées sous des tensions supérieures à 60Volts.When it is necessary to integrate connectors into the wiring networks intended to transmit currents, these connectors must be provided with terminals of size and section large enough to transmit these strong currents without excessive heating. Thus, for example, it may be necessary to use male terminals whose section can reach 113 mm 2 or more. Likewise, the female terminals must be able to receive male terminals having such sections and be protected, in particular when they are used at voltages greater than 60Volts.

Il a déjà été prévu de protéger, notamment conformément à la norme IP2X, l'extrémité des bornes mâles à l'aide d'un embout électriquement isolant et de protéger l'extrémité libre et au moins certaines surfaces externes des bornes femelles à l'aide d'un boîtier ou d'un capuchon protecteur. On pourra se référer notamment aux documents WO2010029391A1 , EP3208892A1 et WO9629761A1 pour avoir des exemples de bornes femelles ainsi protégées par un boîtier protecteur et/ou un autre type d'élément de protection.Provision has already been made to protect, in particular in accordance with the IP2X standard, the end of the male terminals using an electrically insulating tip and to protect the free end and at least certain external surfaces of the female terminals at the using a protective case or cap. We can refer in particular to documents WO2010029391A1 , EP3208892A1 and WO9629761A1 to have examples of female terminals thus protected by a protective housing and / or another type of protective element.

Cependant, il reste possible, notamment pour des contacts ayant des sections supérieures aux dimensions d'un doigt normé (8mm de diamètre), d'atteindre des parties électriquement conductrices situées au niveau de surfaces internes des bornes femelles. Ceci présente un danger potentiel d'électrocution.However, it remains possible, in particular for contacts having sections larger than the dimensions of a standard finger (8mm in diameter), to reach electrically conductive parts situated at the level of internal surfaces of the female terminals. This presents a potential danger of electric shock.

L'invention vise à limiter au moins en partie ce risque d'électrocution.The invention aims to at least partially limit this risk of electric shock.

A cette fin, il est proposé une borne électrique femelle selon la revendication 1 et un en ensemble de connexion de puissance selon la revendication 8.To this end, a female electrical terminal according to claim 1 and a power connection assembly according to claim 8 are proposed.

La borne électrique femelle comporte en outre éventuellement, l'une ou l'autre des caractéristiques énoncées dans les revendications 2 à 5, considérée isolément ou en combinaison d'une ou plusieurs autres.The female electrical terminal also optionally includes one or other of the characteristics set out in claims 2 to 5, considered in isolation or in combination with one or more others.

Ainsi grâce à l'invention, le doigt de l'élément de protection gêne, voire empêche l'insertion d'un doigt ou d'un outil à l'intérieur de la portion de contact de la borne femelle. Ceci limite au moins en partie un risque d'électrocution par contact avec la surface interne de la portion de contact de la borne femelle.Thus thanks to the invention, the finger of the protective element hinders, or even prevents the insertion of a finger or a tool inside the contact portion of the female terminal. This at least partially limits a risk of electrocution by contact with the internal surface of the contact portion of the female terminal.

La borne électrique mâle comporte une broche essentiellement cylindrique, s'étendant longitudinalement parallèlement à l'axe d'accouplement lorsque la borne électrique mâle et la borne électrique femelle sont accouplées, cette broche comportant une extrémité libre, ainsi qu'une surface externe adaptée pour établir un contact électrique avec la surface interne de la borne électrique femelle. La borne électrique mâle comporte éventuellement une broche comportant une couronne électriquement isolante, entourant une entrée de la cavité, au niveau de l'extrémité libre de la broche.The male electrical terminal comprises a substantially cylindrical pin, extending longitudinally parallel to the coupling axis when the male electrical terminal and the female electrical terminal are coupled, this pin having a free end, as well as an external surface suitable for establish electrical contact with the internal surface of the female electrical terminal. The male electrical terminal optionally includes a pin comprising an electrically insulating crown, surrounding an entrance to the cavity, at the free end of the pin.

Eventuellement, dans l'ensemble de connexion comporte la caractéristique énoncée à la revendication 9.Optionally, in the connection assembly includes the characteristic set out in claim 9.

Selon un autre aspect, l'invention est un procédé de montage d'une borne électrique femelle, tel que mentionné à la revendication 6.According to another aspect, the invention is a method of mounting a female electrical terminal, as mentioned in claim 6.

Eventuellement, ce procédé comporte la caractéristique énoncée à la revendication 7.Optionally, this process includes the characteristic set out in claim 7.

Un exemple d'un ensemble de connexion 1 selon l'invention est représenté sur la figure 1. Il comporte un boîtier de connecteur mâle 2 et un boîtier de connecteur femelle 3 (non-représenté sur la figure 1, voir figure 2). Les boîtiers de connecteur mâle 2 et femelle 3 sont essentiellement constitués d'une matière électriquement isolante. Deux bornes électriques mâles 4 reliées à des câbles 5 électriques sont montées dans le boîtier de connecteur mâle 2. Deux bornes électriques femelles 6 reliées à des câbles électriques (non-représentés) sont montées dans le boîtier de connecteur femelle 3. Les deux bornes électriques femelles 6 destinées à être accouplées, selon un axe d'accouplement A, chacune respectivement à une borne électrique mâle 4 montée dans le boîtier de connecteur mâle 2. Sur la figure 1, seule une borne électrique femelle 6 est représentée.An example of a connection assembly 1 according to the invention is shown in the figure 1 . It includes a male connector housing 2 and a female connector housing 3 (not shown in the figure 1 , see figure 2 ). The male 2 and female 3 connector housings are essentially made of an electrically insulating material. Two male electrical terminals 4 connected to electrical cables 5 are mounted in the male connector housing 2. Two female electrical terminals 6 connected to electrical cables (not shown) are mounted in the female connector housing 3. The two electrical terminals females 6 intended to be coupled, along a coupling axis A, each respectively to a male electrical terminal 4 mounted in the male connector housing 2. On the figure 1 , only a female electrical terminal 6 is shown.

La borne électrique femelle 6 comporte une portion de fixation 7 et une portion de contact 8. Les portions de fixation 7 et de contact 8 sont formées dans cet exemple d'une pièce monobloc qui peut être constituée d'un matériau électriquement conducteur. Cette pièce monobloc est formée à partir d'une tôle découpée et courbée.The female electrical terminal 6 comprises a fixing portion 7 and a contact portion 8. The fixing portions 7 and contact 8 are formed in this example from a single piece which can be made of an electrically conductive material. This monobloc piece is formed from a cut and curved sheet.

La portion de fixation 7 est représentée sur les figures 1, 4 et 5 avec des ailettes de sertissage 9 destinées à attacher mécaniquement la borne électrique femelle 6 à un câble d'un réseau électrique (non-représenté). Sur les figures 1, 4 et 5, les ailettes de sertissage 9 sont représentées en position ouverte, avant sertissage sur un câble.The fixing portion 7 is shown on the figures 1 , 4 and 5 with crimping fins 9 intended to mechanically attach the female electrical terminal 6 to a cable of an electrical network (not shown). On the figures 1 , 4 and 5 , the crimping fins 9 are shown in the open position, before crimping on a cable.

Comme représenté sur les figures 4 et 5, la portion de contact 8 a une forme essentiellement tubulaire s'étendant longitudinalement parallèlement à l'axe d'accouplement A, entre une extrémité libre 10 et une extrémité mécaniquement solidaire de la portion de fixation 7. Elle a une surface interne et une surface externe. Elle comporte une bague 12 tubulaire reliée à la portion de fixation 7. Elle comporte également des languettes 13 de contact élastiques s'étendant, essentiellement longitudinalement parallèlement à l'axe d'accouplement A, à partir de la bague 12 vers l'extrémité libre 10.As shown on Figures 4 and 5 , the contact portion 8 has an essentially tubular shape extending longitudinally parallel to the coupling axis A, between a free end 10 and an end mechanically integral with the fixing portion 7. It has an internal surface and a surface external. It comprises a tubular ring 12 connected to the fixing portion 7. It also includes elastic contact tongues 13 extending, essentially longitudinally parallel to the coupling axis A, from the ring 12 towards the free end 10.

Chaque languette 13 a une portion essentiellement rectiligne reliée à la bague 12 et une portion courbée 14 vers l'extrémité libre 10. La portion courbée 14 présente une surface de contact convexe dirigée vers un axe central longitudinal de la portion de contact 8 (l'axe central longitudinal est confondu sur les figures 4 et 5 avec l'axe d'accouplement A). Les languettes 13 sont réparties de manière essentiellement uniforme sur un bord de la bague 12. Elles sont espacées régulièrement. Autrement dit, une fente 15 sépare deux languettes 13 voisines.Each tongue 13 has a substantially rectilinear portion connected to the ring 12 and a curved portion 14 towards the free end 10. The curved portion 14 has a convex contact surface directed towards a longitudinal central axis of the contact portion 8 (the longitudinal central axis coincides on the Figures 4 and 5 with the coupling pin A). The tongues 13 are distributed in an essentially uniform manner on one edge of the ring 12. They are spaced regularly. In other words, a slot 15 separates two neighboring tabs 13.

La borne électrique femelle 6 comporte aussi un boîtier protecteur 16, constitué d'un matériau électriquement isolant. Ce boîtier 16 protecteur peut être également utilisé pour la rétention de la borne électrique femelle 6 dans le boîtier de connecteur femelle 3. Comme représenté sur les figures 1, 2 et 7 ce boîtier protecteur 16 se présente par exemple sous la forme d'un capuchon essentiellement cylindrique s'étendant longitudinalement parallèlement à l'axe d'accouplement A. Il comporte deux ouvertures 17 diamétralement opposées destinées à recevoir des crochets 18 portés par des pattes élastiques 19 venues de matière avec le boîtier de connecteur femelle 3. Ainsi, la borne électrique femelle 6 peut être montée et clipsée dans le boîtier de connecteur femelle 3. Le boîtier protecteur 16 recouvre, par sa paroi cylindrique 20, essentiellement la portion de contact 8, et par des corniches 21 s'étendant radialement vers l'intérieur de la paroi cylindrique 20, l'extrémité libre 10 de la portion de contact 8, et notamment l'extrémité libre d'au moins certaines des languettes de contact élastiques 13. Les corniches 21 laissent un passage central pour insérer une broche 22 d'une borne électrique mâle 4. Ce passage peut correspondre par exemple à un diamètre de 12,3 mm, c'est-à-dire supérieur à celui qui permettrait de répondre à la norme IP2X (qui limite les dimensions de ce type de passage afin d'éviter qu'un utilisateur ne s'électrocute en y introduisant l'extrémité d'un doigt 23).The female electrical terminal 6 also includes a protective housing 16, made of an electrically insulating material. This protective housing 16 can also be used for the retention of the female electrical terminal 6 in the female connector housing 3. As shown in the figures 1, 2 and 7 this protective housing 16 is for example in the form of an essentially cylindrical cap extending longitudinally parallel to the coupling axis A. It has two diametrically opposite openings 17 intended to receive hooks 18 carried by elastic tabs 19 integral with the female connector housing 3. Thus, the female electrical terminal 6 can be mounted and clipped into the female connector housing 3. The protective housing 16 covers, by its cylindrical wall 20, essentially the contact portion 8, and by cornices 21 extending radially inwards from the cylindrical wall 20, the free end 10 of the contact portion 8, and in particular the free end of at least some of the elastic contact tabs 13. The cornices 21 leave a central passage for inserting a pin 22 of a male electrical terminal 4. This passage can correspond for example to a diameter of 12 , 3 mm, that is to say greater than that which would meet the IP2X standard (which limits the dimensions of this type of passage to prevent a user from being electrocuted by inserting the end with a finger 23).

La borne électrique femelle 6 comporte également un élément de protection 24 en matériau électriquement isolant (voir figures 1 à 7). Comme représenté sur la figure 3 notamment, l'élément de protection 24 comporte une base 25 et un doigt 26, tous deux essentiellement cylindrique, s'étendant longitudinalement parallèlement à l'axe d'accouplement A. La base 25 présente un rayon supérieur à celui du doigt 26. Le doigt 26 présente, au niveau de son extrémité libre 27, une surface apicale essentiellement perpendiculaire à l'axe de d'accouplement A. L'élément de protection 24 comporte des moyens d'accrochage. Par exemple, ces moyens d'accrochage se présentent sous la forme trois pattes de fixation élastiques : deux pattes de fixation internes 28 et une patte de fixation externe 29 (voir aussi figure 6). Les pattes de fixation internes 28 et externe 29 s'étendent longitudinalement essentiellement parallèlement à l'axe d'accouplement A. L'une des extrémités longitudinales des pattes de fixation internes 28 et externe 29 est reliée à un rebord 30 s'étendant radialement vers l'extérieur à partir de la base 25. L'autre extrémité longitudinale est libre et munie d'un crochet 31. Chaque crochet 31 forme un ergot adapté pour s'insérer dans une fente 15 entre deux languettes 13, au niveau de la base de celles-ci, en butée sur la bague 12. L'ergot de chaque patte de fixation interne 28 fait donc saillie sur une face externe de chaque patte de fixation interne 28. Réciproquement, l'ergot de la patte de fixation externe 29 fait saillie sur une face interne de la patte de fixation externe 29.The female electrical terminal 6 also includes a protective element 24 made of electrically insulating material (see Figures 1 to 7 ). As shown in the figure 3 in particular, the protective element 24 comprises a base 25 and a finger 26, both essentially cylindrical, extending longitudinally parallel to the coupling axis A. The base 25 has a radius greater than that of the finger 26. The finger 26 has, at its free end 27, an apical surface essentially perpendicular to the coupling axis A. The protective element 24 includes attachment means. For example, these attachment means are in the form of three elastic fixing lugs: two internal fixing lugs 28 and an external fixing lug 29 (see also figure 6 ). The internal 28 and external 29 fixing lugs extend longitudinally essentially parallel to the coupling axis A. One of the longitudinal ends of the internal 28 and external 29 fixing lugs is connected to a flange 30 extending radially towards the exterior from the base 25. The other longitudinal end is free and provided with a hook 31. Each hook 31 forms a lug adapted to be inserted in a slot 15 between two tabs 13, at the base of these, in abutment on the ring 12. The lug of each internal fixing lug 28 therefore projects on an external face of each internal fixing lug 28. Conversely, the lug of the external fixing lug 29 makes projection on an internal face of the external fixing lug 29.

Deux encoches 32 diamétralement opposées sont ménagées dans la base 25 pour permettre respectivement à chacune des pattes fixation internes 28 de fléchir en direction de l'axe central longitudinal de la portion de contact 8.Two diametrically opposite notches 32 are formed in the base 25 to allow each of the internal fixing lugs 28 to flex respectively towards the longitudinal central axis of the contact portion 8.

Pour le montage de l'élément de protection 24 dans la borne électrique femelle 6, on insère le doigt 26 dans la bague 12, par l'extrémité de la bague 12 située vers la portion de fixation 7. Puis, on pousse l'élément de protection 24 vers l'extrémité libre 10 de la portion de contact 8, jusqu'à ce que les crochets 31 se bloquent à la base des fentes 15, derrière la bague 12, et coopèrent ainsi avec la borne électrique femelle 6 pour maintenir l'élément de protection 24 accroché sur celle-ci. La base 25 est maintenue avec un faible jeu au niveau de la bague 12. L'insertion ainsi ajustée entre l'élément de protection 24 et la borne électrique femelle 6 permet un positionnement précis du doigt 26 de manière centrée dans la portion de contact 8. La force de rétention de l'élément de protection 24 dans la borne électrique femelle 6 est par exemple supérieure à 30N. Ainsi, même en appuyant sur l'extrémité libre 27 du doigt 26, il demeure pratiquement impossible de déplacer l'élément de protection 24 et de toucher une languette de contact 13. On notera qu'il est préférable, car plus aisé, de monter l'élément de protection 24 avant l'opération de sertissage d'un câble au niveau de la portion de fixation 7, c'est-à-dire lorsque les ailettes de sertissage 9 sont ouvertes. On notera également que la base 25 est moins longue (parallèlement à l'axe d'accouplement A) dans un secteur inférieur que dans un secteur supérieur (le secteur inférieur étant situé à l'opposé, par rapport aux pattes de fixation internes, du secteur supérieur qui comporte lui la patte de fixation externe). Ainsi, l'insertion de l'élément de protection 24 dans la portion de contact 8 est rendue plus aisée.To mount the protective element 24 in the female electrical terminal 6, insert the finger 26 into the ring 12, through the end of the ring 12 located towards the fixing portion 7. Then, push the element of protection 24 towards the free end 10 of the contact portion 8, until the hooks 31 lock at the base of the slots 15, behind the ring 12, and thus cooperate with the female electrical terminal 6 to maintain the 'protective element 24 hooked thereon. The base 25 is held with a slight clearance at the level of the ring 12. The insertion thus adjusted between the protective element 24 and the female electrical terminal 6 allows precise positioning of the finger 26 in a centered manner in the contact portion 8 The retention force of the protective element 24 in the female electrical terminal 6 is for example greater than 30N. Thus, even by pressing on the free end 27 of the finger 26, it remains practically impossible to move the protective element 24 and to touch a contact tab 13. It will be noted that it is preferable, because easier, to mount the protective element 24 before the crimping operation of a cable at the fixing portion 7, that is to say when the crimping fins 9 are open. It will also be noted that the base 25 is shorter (parallel to the coupling axis A) in a lower sector than in an upper sector (the lower sector being located opposite, with respect to the internal fixing lugs, of the sector upper which has the external fixing tab). Thus, the insertion of the protective element 24 in the contact portion 8 is made easier.

L'élément de protection 24 est optionnel. On choisira de le monter, ou non, en fonction de l'application qui sera faite de la borne électrique femelle 6 et du risque l'électrocution encouru lié à l'usage fait de la borne électrique femelle 6.The protective element 24 is optional. We will choose to mount it, or not, depending on the application that will be made of the female electrical terminal 6 and the risk of electrocution incurred related to the use made of the female electrical terminal 6.

Lorsque l'élément de protection 24 est monté sur la borne électrique femelle 6, comme représenté sur la figure 7, la distance entre les corniches 21 et l'extrémité du doigt 26 est suffisamment réduite pour répondre à la norme IP2X.When the protective element 24 is mounted on the female electrical terminal 6, as shown in the figure 7 , the distance between the cornices 21 and the end of the finger 26 is reduced enough to meet the IP2X standard.

La borne électrique mâle 4 a une structure générale d'un type déjà connu (voir notamment les figures 2 et 8). Ne seront donc décrits ici que les aspects particuliers de l'invention. Ainsi, la borne électrique mâle 4 comporte une broche 22 essentiellement cylindrique s'étendant longitudinalement parallèlement à l'axe d'accouplement A, en direction d'une extrémité libre 33 destinée à s'engager dans la borne électrique femelle 6 et établir un contact électrique à l'intérieur de la portion de contact 8 de celle-ci. Cette broche 22 est formée dans un barreau de matériau électriquement conducteur. Une couronne 34 électriquement isolante est montée sur l'extrémité libre 33. Une portion terminale de la broche 22 est percée, par exemple par alésage, d'une cavité 35 cylindrique centrale s'étendant parallèlement à l'axe d'accouplement A. Cette cavité 35 se prolonge à travers la couronne 34 par un passage.The male electrical terminal 4 has a general structure of a type already known (see in particular the figures 2 and 8 ). Only the specific aspects of the invention will therefore be described here. Thus, the male electrical terminal 4 comprises a substantially cylindrical pin 22 extending longitudinally parallel to the coupling axis A, in the direction of a free end 33 intended to engage in the female electrical terminal 6 and establish contact electric inside the contact portion 8 thereof. This pin 22 is formed in a bar of electrically conductive material. An electrically insulating ring 34 is mounted on the free end 33. An end portion of the pin 22 is pierced, for example by boring, with a central cylindrical cavity 35 extending parallel to the coupling axis A. This cavity 35 is extended through the crown 34 by a passage.

Lors de l'accouplement du boitier de connecteur femelle 3 avec le boitier de connecteur mâle 2, ces boîtiers s'interpénètrent de manière à ce que chaque borne électrique mâle 4 s'engage respectivement dans la portion de contact 8 d'une borne électrique femelle 6 (voir figure 2). Le doigt 26 pénètre alors par le passage ménagé dans la couronne 34, puis dans la cavité 35. Le contact électrique entre la surface externe de la broche 22 de la borne électrique mâle 4 et la surface interne de la portion de contact 8 de la borne électrique femelle 6 est établi sur au moins un point de contact 36 situé, en projection sur l'axe d'accouplement A et en partant de l'extrémité libre 33 de la broche 22, essentiellement au niveau ou au-delà du fond de la cavité 35. Ainsi, les lignes de courant peuvent passer par un chemin correspondant essentiellement à une section pleine de la broche 22 (une section par exemple de 113mm2). Ce type de configuration est évidemment plus favorable au passage de courants forts par rapport à un contact électrique qui se ferait au niveau de la cavité 35 et qui correspondrait donc à un disque présentant une surface, par exemple de 84,7mm2, donc à une section nettement moindre que la section maximale de la broche.When the female connector box 3 is coupled with the male connector box 2, these boxes interpenetrate so that each male electrical terminal 4 engages respectively in the contact portion 8 of a female electrical terminal 6 (see figure 2 ). The finger 26 then enters through the passage formed in the crown 34, then in the cavity 35. The electrical contact between the external surface of the pin 22 of the male electrical terminal 4 and the internal surface of the contact portion 8 of the terminal female electrical 6 is established on at least one contact point 36 located, in projection on the coupling axis A and starting from the free end 33 of the pin 22, essentially at or beyond the bottom of the cavity 35. Thus, the current lines can pass through a path corresponding essentially to a solid section of the pin 22 (a section for example of 113 mm 2 ). This type of configuration is obviously more favorable for the passage of strong currents compared to an electrical contact which would be made at the level of the cavity 35 and which would therefore correspond to a disc having a surface, for example of 84.7mm 2 , therefore with a much smaller section than the maximum section of the spindle.
