Description

La présente invention concerne un dispositif de connexion perpendiculaire entre deux éléments, ainsi que le connecteur étanche et à double verrouillage obtenu.The present invention relates to a device for connecting perpendicularly between two elements, as well as the waterproof connector and double locking obtained.

En connectique et plus particulièrement dans le milieu automobile, on est à la recherche de dispositifs de connexion qui permettent d'établir des liaisons électriques fiables, à un moindre coût et qui soient démontables, généralement l'une des pièces faisant partie d'un réseau fixe et l'autre pouvant être retirée en vue de son remplacement.Connectivity and more particularly in the automotive industry, we are looking for connection devices that allow to establish reliable electrical connections, at a lower cost and which are removable, usually one of the parts forming part of a network fixed and the other withdrawable for replacement.

Les contraintes supplémentaires sont nombreuses puisqu'il faut que de tels dispositifs de connexion supportent les vibrations sans perdre la pression de contact qui assure la continuité électrique, qu'ils se montent de façon aisée sans qu'il puisse y avoir d'erreurs lors de la mise en place, qu'ils soient étanches et qu'ils bénéficient d'un verrouillage mécanique de grande fiabilité.The additional constraints are numerous since it is necessary for such connection devices to withstand the vibrations without losing the contact pressure which ensures the electrical continuity, that they mount easily without there being any errors during the installation, that they are waterproof and that they benefit from a mechanical lock of great reliability.

De plus, on note que ces dispositifs de connexion sont fréquemment situés dans des endroits difficilement accessibles, ce qui oblige le concepteur à réaliser des configurations particulières de connexion.In addition, it is noted that these connection devices are frequently located in hard to reach places, which forces the designer to make particular connection configurations.

C'est ainsi que dans le cas où les parties à raccorder sont disposées selon des plans perpendiculaires, la difficulté est augmentée par les mouvements respectifs des deux éléments lors des vibrations ou des chocs car les directions et les sens des efforts auxquels ils sont soumis sont souvent complexes, voire opposés.Thus, in the case where the parts to be connected are arranged in perpendicular planes, the difficulty is increased by the respective movements of the two elements during vibrations or shocks because the directions and the directions of the forces to which they are subjected are often complex, even opposed.

Le dispositif de connexion doit être étanche de préférence lorsqu'il est utilisé dans un compartiment moteur automobile et comprendre de préférence un double verrouillage pour assurer le maintien en position, même dans des conditions extrêmes.The connection device should preferably be sealed when used in an automotive engine compartment and preferably include double locking to maintain the position even under extreme conditions.

La présente invention vise à pallier ces inconvénients et le dispositif de connexion selon l'invention est fiable, d'un coût de revient compatible notamment avec les prix des fournitures pour le marché automobile, d'un montage aisé et rapide sans possibilité d'erreur au cours dudit montage. Ce dispositif assure également une liaison mécanique fiable et un démontage facile.The present invention aims to overcome these drawbacks and the connection device according to the invention is reliable, a cost compatible with the prices of supplies for the automotive market, easy assembly and fast without possibility of error during said assembly. This device also provides a reliable mechanical connection and easy disassembly.

Selon l'invention, le dispositif de connexion électrique est défini par la revendication 1.According to the invention, the electrical connection device is defined by claim 1.

Plus particulièrement, le ou les contact(s) sont constitués d'une zone dénudée d'une bande métallique allongée dans une direction perpendiculaire à l'axe d'emboîtement de la partie mâle dans la partie femelle. Cette bande métallique du ou des contact(s) est insérée dans une embase isolante qui est un surmoulage, la zone dénudée correspondant à une épargne dudit surmoulage.More particularly, the contact (s) consist of a stripped zone of an elongated metal strip in a direction perpendicular to the interlocking axis of the male part in the female part. This metal band of the contact (s) is inserted into an insulating base which is an overmoulding, the stripped zone corresponding to a saving of said overmoulding.

Plus spécifiquement, le dispositif comprend au moins deux bandes métalliques, ces deux bandes métalliques juxtaposées étant séparées entre elles par une cloison isolante venue de moulage avec l'embase isolante.More specifically, the device comprises at least two metal strips, these two juxtaposed metal strips being separated from each other by an insulating wall integrally molded with the insulating base.

Selon une autre caractéristique, chaque lame du ou des contact(s) de la partie femelle comprend une surface de contact délimitée par deux pliages transversaux qui autorisent un désaxage de ladite surface par rapport à l'axe longitudinal de l'embase.According to another characteristic, each blade of the contact (s) of the female part comprises a contact surface defined by two transverse folds which allow an offset of said surface relative to the longitudinal axis of the base.

Le boîtier porte-contacts comprend des premiers moyens et des seconds moyens de verrouillage du ou des contacts femelles sur chaque lame correspondante.The contact holder housing comprises first means and second means for locking the female contact or contacts on each corresponding blade.

L'invention a aussi pour objet le connecteur électrique correspondant, à emboîtement perpendiculaire qui comprend une matrice dans laquelle est intégré l'ensemble de l'embase et des contacts de la partie femelle, ladite matrice étant munie d'un logement à profil conjugué de la tête du boîtier porte-contacts et de moyens d'étanchéité.The invention also relates to the corresponding electrical connector, perpendicular interlocking which comprises a matrix in which is integrated the entire base and contacts of the female part, said matrix being provided with a housing with a conjugate profile of the head of the contact holder housing and sealing means.

Des joints assurent l'étanchéité de l'ensemble après emboîtement.Seals seal the assembly after interlocking.

De plus, des moyens de bridage des parties mâle et femelle sécurise l'accroche.In addition, clamping means of the male and female parts secures the grip.

L'invention est maintenant décrite en regard des dessins annexés selon un mode de réalisation particulier, non limitatif, les différentes figures des dessins représentant :

  • figure 1, une vue en perspective éclatée des parties mâle et femelle à connecter dans le cas particulier d'un dispositif de connexion,
  • figures 2A et 2B, deux vues en coupe longitudinale, respectivement en position de pré-introduction et d'introduction complète de la partie mâle dans la partie femelle, dans le cas d'une connexion avec un encliquetage correct,
  • figure 3, une vue de face de la partie femelle, avant présentation de la partie mâle,
  • figure 4, une vue en coupe suivant la ligne 4-4 de la figure 20, pour montrer l'agencement des différentes pièces, et
  • figure 5, une vue d'un cas de connexion avec un encliquetage défectueux.
The invention is now described with reference to the accompanying drawings in a particular, nonlimiting embodiment, the various figures of the drawings showing:
  • figure 1 an exploded perspective view of the male and female parts to be connected in the particular case of a connection device,
  • Figures 2A and 2B , two views in longitudinal section, respectively in pre-introduction position and full introduction of the male part into the female part, in the case of a connection with a correct snap,
  • figure 3 , a front view of the female part, before presentation of the male part,
  • figure 4 a sectional view along the line 4-4 of FIG. 20 to show the arrangement of the different pieces, and
  • figure 5 , a view of a connection case with a faulty snap-in.

Sur la figure 1, on a représenté un dispositif de connexion comprenant une partie femelle 10 et une partie mâle 12, prévues pour coopérer par encliquetage l'une avec l'autre, des moyens 14 d'étanchéité et des moyens 16 de bridage.On the figure 1 , there is shown a connection device comprising a female portion 10 and a male portion 12, provided to cooperate by snapping together, means 14 for sealing and means 16 for clamping.

La partie femelle 10 comprend deux contacts 18, chacun sous forme d'une lame, maintenus dans une embase 20, isolante. Cette lame est réalisée dans une bande métallique allongée dans une direction perpendiculaire à l'axe de connexion.The female part 10 comprises two contacts 18, each in the form of a blade, held in an insulating base 20. This blade is made in a elongated metal strip in a direction perpendicular to the connection axis.

Cette embase est avantageusement en matière plastique surmoulée sur la majeure partie des lames à l'exception d'un épargne lors du surmoulage, définissant une zone 21 dénudée de connexion où les lames de contact 18 sont dégagées. On note que pour une meilleure compréhension, les contacts sont représentés deux fois sur la figure 1, l'une extérieurs à l'embase et l'autre intégrés à l'embase mais il n'est besoin que d'une paire de contacts pour le mode de réalisation représenté.This base is advantageously plastic overmoulded on most of the blades except a savings during overmolding, defining a zone 21 stripped connection where the contact blades 18 are cleared. We note that for a better understanding, the contacts are represented twice on the figure 1 , one external to the base and the other integrated into the base but only one pair of contacts is needed for the embodiment shown.

Dans le mode de réalisation représenté sur la figure 1, chaque lame de contact 18 comprend deux pliages 22, 22' transversaux qui déterminent pour chacun un bossage ou méplat 24 définissant ainsi deux surfaces de contact comportant sur une de leurs arêtes communes une lèvre 26 amincie facilitant l'introduction d'un contact complémentaire décrit ultérieurement. Ce bossage ou méplat est désaxé par rapport à l'axe longitudinal de l'embase pour former une saillie permettant un libre accès à chacune des surfaces ainsi définies.In the embodiment shown on the figure 1 each contact blade 18 comprises two folds 22, 22 'transverse which each determine a boss or flat 24 thus defining two contact surfaces comprising on one of their common edges a thinned lip 26 facilitating the introduction of a complementary contact described later. This boss or flat is off-axis with respect to the longitudinal axis of the base to form a projection allowing free access to each of the surfaces thus defined.

La partie mâle 12 comprend un boîtier porte-contacts 28 avec un alvéole 30, une extrémité frontale 32 et des moyens 34 de réception des moyens 16 de bridage.The male portion 12 comprises a contact holder housing 28 with a cell 30, a front end 32 and means 34 for receiving the means 16 for clamping.

Pour décrire les éléments portés par le corps et la tête, on se reporte aux figures 2A et 2B sur lesquelles les éléments identiques portent les mêmes références.To describe the elements carried by the body and the head, we refer to Figures 2A and 2B on which the identical elements bear the same references.

Les alvéoles 30 du boîtier porte-contacts 28 reçoivent deux contacts femelles 36, seul l'un d'eux étant visible sur la figure 2B, vue en coupe longitudinale.The cells 30 of the contact holder housing 28 receive two female contacts 36, only one of them being visible on the Figure 2B , longitudinal sectional view.

Dans le mode de réalisation représenté, chaque contact femelle 36 comprend, à l'avant, des lames 37 élastiques formant pince, généralement venues de pliage et prévues pour coopérer avec les surfaces du méplat 24 du contact 18, en position encliquetée comme cela sera expliqué ultérieurement. On constate que les lames 18 sont bien orientées perpendiculairement à l'axe d'emboîtement du boîtier 28 porte-contactsIn the embodiment shown, each female contact 36 comprises, at the front, elastic blades 37 forming a clamp, generally folded and adapted to cooperate with the surfaces of the flat portion 24 of the contact 18, in the interlocked position as will be explained later. It can be seen that the blades 18 are oriented perpendicularly to the interlocking axis of the housing 28 contact-carrier

Chacun des contacts 36 se prolonge, à l'arrière, par une zone 38 de liaison avec un fil électrique 40. Au droit de cette zone 38, le dispositif comprend avantageusement un joint 42 d'étanchéité.Each of the contacts 36 is extended, at the rear, by a zone 38 of connection with an electrical wire 40. In line with this zone 38, the device advantageously comprises a seal 42.

Chacun des contacts 36 est immobilisé dans l'alvéole 30 du boîtier porte-contacts par un premier moyen 44 de verrouillage.Each of the contacts 36 is immobilized in the cell 30 of the contact holder housing by a first locking means 44.

Ce premier moyen de verrouillage comprend un linguet 46 qui peut prendre une première position dans laquelle il est soulevé, comme on le voit sur la figure 5, pour laisser passer le contact et une seconde position dans laquelle il est droit pour immobiliser le contact dans l'alvéole 30.This first locking means comprises a pawl 46 which can take a first position in which it is lifted, as can be seen on the figure 5 , to let the contact and a second position in which it is straight to immobilize the contact in the cell 30.

Il est en outre prévu un second moyen 48 de verrouillage qui est lié dans son fonctionnement au premier moyen 44. Ce second moyen comprend une plaquette 50 mobile en translation par rapport à l'alvéole 30, entre une première position, sur l'avant, pour venir en butée sur la partie femelle ainsi que cela sera expliqué ultérieurement et une seconde position, sur l'arrière, après encliquetage, pour venir se loger entre la surface intérieure de l'alvéole 30 du boîtier porte-contacts et le linguet 46 en sorte d'interdire le soulèvement de ce dernier, constituant ainsi un double verrouillage de chaque contact.There is further provided a second locking means 48 which is connected in its operation to the first means 44. This second means comprises a plate 50 movable in translation relative to the cell 30, between a first position, on the front, to abut on the female part as will be explained later and a second position, on the rear, after snapping, to be housed between the inner surface of the cell 30 of the contact holder housing and the pawl 46 in to prohibit the lifting of the latter, thus constituting a double lock of each contact.

La tête 32 a un profil cylindrique dont la partie centrale a été dégagée pour permettre le passage de l'embase 20 isolante.The head 32 has a cylindrical profile whose central portion has been disengaged to allow the passage of the insulating base 20.

Le corps 30 du boîtier porte-contacts porte également une collerette 62 annulaire adaptée pour recevoir un joint 64 de type torique qui constitue les moyens 14 d'étanchéité entre les parties mâle et femelle.The body 30 of the contact holder case also carries an annular flange 62 adapted to receive a ring-type seal 64 which constitutes the means 14 for sealing between the male and female parts.

Comme cela est représenté sur les figures 1 et 4, les moyens 16 de bridage comporte deux ergots latéraux, 66 et 68 disposés de part et d'autre de l'alvéole 30 du boîtier porte-contacts et une bride 70 de fixation.As shown on the figures 1 and 4 , the clamping means 16 comprises two lateral lugs, 66 and 68 disposed on either side of the cell 30 of the contact holder housing and a clamp 70.

Le premier ergot 66 est constitué d'un axe 72 autour duquel peut pivoter l'une des extrémités de la bride de fixation et le second ergot 68 est constitué d'un plot 74 à profil conjugué de l'extrémité libre de la bride pour assurer un blocage élastique.The first lug 66 consists of an axis 72 around which one of the ends of the fixing flange can pivot and the second lug 68 consists of a stud 74 with a conjugate profile of the free end of the flange to ensure an elastic lock.

Cette bride 70 de fixation comprend deux oreilles 76 pliées en V pour assurer un bridage à effet de rappel élastique de la partie mâle sur la partie femelle, en permettant un écrasement du joint 64 d'étanchéité pour qu'il remplisse sa fonction.This fastening flange 70 comprises two lugs 76 folded in a V- shaped manner to provide resiliently biasing of the male part to the female part, allowing the sealing gasket 64 to be crushed so that it performs its function.

En se reportant plus particulièrement aux figures 2A et 2B, on note que l'ensemble de l'embase 20 et des lames de la partie femelle est noyé dans une matrice 75 en matériau polymère qui présente un logement 76 prévu pour recevoir la tête 32 du boîtier porte-contacts et une portée 78, périphérique à ce logement, prévue pour recevoir en appui le joint 64 torique.With particular reference to Figures 2A and 2B , note that the entire base 20 and the blades of the female part is embedded in a matrix 75 of polymeric material which has a housing 76 provided to receive the head 32 of the contact holder housing and a bearing 78, peripheral to this housing, provided to receive in support the ring 64 ring.

La mise en place d'un tel dispositif de connexion d'une partie mâle avec une partie femelle, orientées perpendiculairement, est indiquée ci-après.The establishment of such a connection device of a male part with a female part, oriented perpendicularly, is indicated below.

Sur la figure 2A, on présente la partie mâle qui comprend l'alvéole 30 du boîtier porte-contacts avec à l'intérieur une paire de contacts 36. Lors du montage, les contacts sont poussés vers la tête 32 du boîtier porte-contacts jusqu'à ce que chacun des contacts soulèvent le linguet 46 en saillie dans l'alvéole 30 puis se bloquent sur l'avant de celui-ci. Le linguet 46 se retrouve en position droite comme montré sur les figures 2A et 2B. Le premier verrouillage 44 est en place.On the Figure 2A the male portion which comprises the cell 30 of the contact carrier housing is presented with a pair of contacts 36 therein. During assembly, the contacts are pushed towards the head 32 of the contact carrier housing until each of the contacts lift the pawl 46 projecting into the cell 30 and then block on the front thereof. The pawl 46 is in the right position as shown on the Figures 2A and 2B . The first lock 44 is in place.

Si l'un des contacts venait à ne pas être en place, ce qui aurait pour conséquence une mauvaise ou même une non connexion des lames 37 du contact de la partie mâle avec la surface 24 des lames 18 de la partie femelle, le linguet 46 reste soulevé ce qui le met dans la position représentée sur la figure 5. On note dans cette position que les contacts ne sont pas en butée et peuvent être retirés ou peuvent être repoussés librement.If one of the contacts should not be in place, which would result in a bad or even a non connection of the blades 37 of the contact of the male part with the surface 24 of the blades 18 of the female part, the pawl 46 remains raised which puts him in the position shown on the figure 5 . It is noted in this position that the contacts are not in abutment and can be removed or can be pushed freely.

Sur la figure 2A, le joint 64 torique n'est pas pressé. On note par contre que le joint 42 d'étanchéité du contact par rapport au porte-contacts est actif puisqu'il a été introduit simultanément au montage des contacts dans l'alvéole 30.On the Figure 2A the toric seal 64 is not pressed. On the other hand, it should be noted that the gasket 42 for sealing the contact with respect to the contact holder is active since it was introduced simultaneously with the mounting of the contacts in the cell 30.

Pour assurer la mise en place finale de la connexion, les deux parties mâle 12 et femelle 10 sont rapprochées et la tête 32 de la partie mâle pénètre dans le logement 76 ménagé dans la matrice 75 support de l'embase 20. Simultanément, les lames 37 des contacts 36 se glissent de part et d'autre de la surface 24 de contact de la lame 18 correspondante de la partie femelle.To ensure the final establishment of the connection, the two male parts 12 and female 10 are brought together and the head 32 of the male part enters the housing 76 formed in the matrix 75 support of the base 20. Simultaneously, the blades 37 contacts 36 slide on both sides of the contact surface 24 of the corresponding blade 18 of the female part.

La tête 32 assure un guidage par rapport à l'embase 20.The head 32 provides a guide relative to the base 20.

Le double verrouillage est assuré lors de ce mouvement d'approche et d'encliquetage.Double locking is ensured during this movement of approach and snap.

La plaquette 50 vient en appui sur une partie 51 venue de moulage avec l'embase, ce qui a pour effet de provoquer la translation de cette même plaquette et de la pousser entre le linguet 46 et la face intérieure de l'alvéole 30 du boîtier porte-contacts, ce qui assure l'immobilisation de celui-ci en position droite de verrouillage des contacts. La partie 51 assure aussi l'isolation des deux lames 18 en formant une cloison.The plate 50 bears on a portion 51 molded with the base, which has the effect of causing the translation of the same plate and push between the pawl 46 and the inner face of the cell 30 of the housing contact holder, which ensures the immobilization of the latter in the right position of locking the contacts. The portion 51 also insulates the two blades 18 forming a partition.

On note comme cela est visible sur la figure 5 que le montage du boîtier porte-contacts est rendu impossible lorsque les contacts ne sont pas en place puisque la plaquette 50 vient en butée contre le linguet 46 qui est soulevé, ce qui rend impossible le rapprochement des parties mâle et femelle. Cela supprime les cas d'encliquetage incorrect.We note as it is visible on the figure 5 that the mounting of the contact carrier case is made impossible when the contacts are not in place since the plate 50 abuts against the pawl 46 which is raised, which makes it impossible to bring the male and female parts together. This removes the cases of incorrect snapping.

Sur la figure 3, on a montré en détail, vue de face, la partie femelle dans sa matrice prête à recevoir la partie mâle.On the figure 3 it has been shown in detail, seen from the front, the female part in its matrix ready to receive the male part.

Sur la figure 4, on appréhende mieux la position respective des différents éléments lors d'un encliquetage correct. On a fait aussi apparaître sur cette figure le montage de la bride 70 de fixation qui, après pivotement autour de l'axe 72 se trouve bloquée élastiquement sur le plot 74, assurant ainsi un bridage élastique de la partie mâle sur la partie femelle. Comme on le voit également sur la figure 2B, le joint 64 torique est alors pressé pour assurer une étanchéité adaptée.On the figure 4 , we better apprehend the respective positions of the various elements during a correct snap. This figure also shows the mounting of the fastening flange 70 which, after pivoting about the axis 72 is resiliently locked on the stud 74, thus ensuring elastic clamping of the male part on the female part. As we also see on the Figure 2B , the O-ring 64 is then pressed to ensure a suitable seal.
