Description

La présente invention concerne un dispositif de verrouillage d'éléments de connecteur et un connecteur le comprenant.The present invention relates to a locking device of connector elements and a connector comprising it.

Les connecteurs électriques, notamment dans leurs applications automobiles, comportent des dispositifs de verrouillage de contacts assurant une 5 forte rétention des contacts dans leurs alvéoles.Electrical connectors, especially in their automotive applications, have contact locking devices which provide strong retention of the contacts in their cells.

Ces dispositifs de verrouillage comportent fréquemment une partie mobile telle qu'une coiffe avant comprenant une face avant, pourvue de trous de passage de languettes de contact venant s'accoupler avec des contacts femelles complémentaires, et des parois latérales enserrant les faces latérales d'un module porte contacts.These locking devices frequently comprise a movable part such as a front cap comprising a front face, provided with contact tab passage holes coming to couple with complementary female contacts, and side walls enclosing the lateral faces of a contact holder module.

L'ensemble coiffe/module constitue ainsi un premier élément de connecteur portant des contacts d'un premier genre destiné à s'accoupler avec un second élément de connecteur portant des contacts d'un second genre complémentaire du premier genre.The cap / module assembly thus constitutes a first connector element carrying contacts of a first type intended to mate with a second connector element carrying contacts of a complementary second genus of the first kind.

Pour permettre un dépannage du connecteur et réaliser une fonction de détection de contact mal inséré, la coiffe est mobile entre une position d'insertionlextraction des contacts et une position de verrouillage des contacts.To allow troubleshooting of the connector and perform a contact detection function improperly inserted, the cap is movable between a position of insertionlextraction of the contacts and a locking position of the contacts.

Il est nécessaire de sécuriser le fonctionnement des connecteurs et, avant l'accouplement des éléments de connecteurs complémentaires, de garantir d'une part que les contacts sont correctement insérés et d'autre part que les dispositifs de verrouillage des contacts sont dans leur position de verrouillage.It is necessary to secure the operation of the connectors and, before the coupling of the complementary connector elements, to ensure on the one hand that the contacts are correctly inserted and on the other hand that the locking devices of the contacts are in their position of locking.

Pour ce faire, la présente invention vise à proposer un dispositif de verrouillage d'une coiffe sur un module porte contacts, la coiffe, porteuse de moyens de verrouillage de contacts disposés dans le module porte contact, s'assemblant sur la face d'accouplement du module porte contacts pour former un premier élément de connecteur, caractérisé en ce qu'il comporte des moyens d'encliquetage de la coiffe sur le module dans une position longitudinale de verrouillage des contacts, et des moyens de butée effaçables s'opposant à l'accouplement de l'élément de connecteur avec un élément de connecteur complémentaire tant que la coiffe n'est pas encliquetée sur le module dans la position de verrouillage des contacts.To do this, the present invention aims at providing a device for locking a cap on a contact holder module, the cap, carrying contact locking means arranged in the contact module, assembling on the coupling face of the contact holder module for forming a first connector element, characterized in that it comprises means for latching the cap on the module in a longitudinal position for locking the contacts, and erasable abutment means opposing the coupling of the connector element with an element of additional connector as long as the cap is not snapped onto the module in the locking position of the contacts.

Selon l'invention, les moyens d'encliquetage comprennent en particulier un levier pourvu d'au moins un doigt de verrouillage, les moyens de butée effaçable 10 comprenant avantageusement une premiere aile du levier.According to the invention, the latching means comprise in particular a lever provided with at least one locking finger, the erasable stop means 10 advantageously comprising a first wing of the lever.

Pour réaliser l'encliquetage de la coiffe dans la position de verrouillage des contacts le dispositif peut comporter un premier doigt de verrouillage, le dispositif comportant en outre un second doigt de verrouillage réalisant l'encliquetage de la coiffe sur le module porte contacts dans une position d'insertionlextraction des contacts.To achieve the latching of the cap in the locking position of the contacts the device may comprise a first locking finger, the device further comprising a second locking pin making it possible to snap the cap onto the contact holder module in a position insertion of the contacts.

En mode de réalisation alternatif, le dispositif comporte un doigt de verrouillage réalisant, dans une première position, l'encliquetage de la coiffe sur le module porte contacts dans la position de verrouillage des contacts et, dans une seconde position, l'encliquetage de la coiffe dans une position d'insertion-extraction des contacts.In the alternative embodiment, the device comprises a locking pin producing, in a first position, the latching of the cap on the contact holder module in the locking position of the contacts and, in a second position, the snapping of the cap in an insertion-extraction position of the contacts.

L'objet de l'invention est de réaliser un dispositif interdisant l'accouplement d'un premier élément de connecteur comportant un module porte contact et une coiffe avant protégeant la partie avant du premier élément de connecteur avec un second élément de connecteur complémentaire dans le cas où le premier élément de connecteur n'est pas correctement assemblé.The object of the invention is to provide a device prohibiting mating a first connector element having a contact module and a front cap protecting the front portion of the first connector element with a second complementary connector element in the case where the first connector element is not correctly assembled.

La figure 1 représente une vue générale d'un tel premier élément de connecteur pourvu d'une coiffe 1 et d'un module 2 porte contacts réalisant après assemblage le premier élément de connecteur 11.The figure 1 represents a general view of such a first connector element provided with a cap 1 and a module 2 door contacts making after assembly the first connector element 11.

Une coupe de l'élément de connecteur coiffe montée sur le module est représentée en figure 6.A section of the cap connector element mounted on the module is shown in FIG. figure 6 .

La coiffe 1 est selon cet exemple porteuse de moyens 3 de verrouillage de contacts 23 disposés dans le module porte contact et reliés à un câble 24.The cap 1 is according to this example carrying means 3 for locking contacts 23 arranged in the contact module and connected to a cable 24.

Les moyens 3 de verrouillage sont ici des moyens de verrouillage secondaire des contacts et appuient sur des linguets 25 de rétention des contacts.The locking means 3 are here secondary locking means of the contacts and pressing on the latches 25 for retention of the contacts.

Une réalisation pour laquelle les moyens de verrouillage 3 sont directement en prise sur les contacts est envisageable selon l'invention.An embodiment for which the locking means 3 are directly engaged with the contacts is conceivable according to the invention.

Selon l'exemple, la coiffe est destinée à s'assembler sur la face 25 d'accouplement du module 2 porte contacts pour former le premier élément de connecteur 11.According to the example, the cap is intended to be assembled on the coupling face of the module 2 door contacts to form the first connector element 11.

La coiffe est représentée en figure 6 dans une position d'insertion extraction des contacts, les moyens 3 n'appuyant pas encore sur les linguets de sorte que ces derniers puissent maintenir les contacts en position mais puissent libérer les contacts si une traction suffisante est appliquée sur le câble ou si le linguet est soulevé par sa partie avant.The cap is represented in figure 6 in an insertion position extraction of the contacts, the means 3 not yet pressing the pawls so that they can hold the contacts in position but can release the contacts if sufficient traction is applied to the cable or if the pawl is raised by its front part.

En revenant à la figure 1 un premier exemple de réalisation du dispositif de verrouillage de la coiffe selon l'invention est représenté. Le dispositif de verrouillage comporte ici un levier 14 solidaire de la coiffe et pivotant sur une face latérale de la coiffe.Returning to figure 1 a first embodiment of the locking device of the cap according to the invention is shown. The locking device here comprises a lever 14 integral with the cap and pivoting on a lateral face of the cap.

Ce premier exemple de réalisation est détaillé plus précisément aux figures 3A à 3B et son utilisation est représentée aux figures 2A et 2B qui représentent l'élément de connecteur de la figure 1 lors de son accouplement avec un élément de connecteur complémentaire 12.This first example of embodiment is detailed more specifically in Figures 3A to 3B and its use is represented in Figures 2A and 2B which represent the connector element of the figure 1 when coupled with a complementary connector element 12.

Le dispositif de verrouillage de la coiffe 1 sur un module 2 porte contacts représenté aux figures 3A à 3C comporte des moyens 4, 5, 6, 14 d'encliquetage de la coiffe 1 sur le module 2.The locking device of the cap 1 on a module 2 door contacts shown in FIGS. 3A to 3C comprises means 4, 5, 6, 14 for latching the cap 1 on the module 2.

Ces moyens d'encliquetage permettent de disposer la coiffe sur le module dans une position longitudinale d'insertion/extraction des contacts et dans une position longitudinale de verrouillage des contacts.These latching means make it possible to arrange the cap on the module in a longitudinal insertion / extraction position of the contacts and in a longitudinal position for locking the contacts.

Selon le mode de réalisation de la figure 1, les moyens d'encliquetage de la coiffe sur le module comprennent un levier 14 pourvu d'au moins un doigt de verrouillage 4.According to the embodiment of the figure 1 , the latching means of the cap on the module comprise a lever 14 provided with at least one locking finger 4.

Selon le mode de réalisation des figures 3A à 3C, le levier 14 est pourvu de deux doigts de verrouillage 4 et 5.According to the embodiment of FIGS. 3A to 3C the lever 14 is provided with two locking fingers 4 and 5.

Le ou les doigts de verrouillage permettent d'encliqueter la coiffe sur le module selon la position d'insertion/extraction des contacts et selon la position de verrouillage des contacts décrites plus haut.The locking finger or fingers can snap the cap on the module according to the position of insertion / extraction of the contacts and the locking position of the contacts described above.

Dans le cas du dispositif à un seul doigt de verrouillage tel que représenté en figure 1, la position d'insertion extraction des contacts peut être une position sans blocage de la coiffe.In the case of the device with a single locking finger as shown in FIG. figure 1 , the contact extraction position of the contacts can be a position without locking the cap.

Dans la version à deux doigts de verrouillage représentée en figures 3A à 3C, la première position est une position stable pour laquelle un premier doigt 4 s'encliquète sur un plot 6 pour positionner la coiffe en position d'insertion/extraction des contacts, le levier restant dans une position inclinée pour laquelle une aile arrière 10 du levier dépasse de l'encombrement extérieur de la coiffe pour interférer avec une partie avancée 16 de l'élément de connecteur complémentaire 12. Le premier doigt de verrouillage est ici solidaire du levier portant un second doigt de verrouillage, mais peut dans une version alternative être dissocié du levier.In the two-finger lock version shown in FIGS. 3A to 3C , the first position is a stable position for which a first finger 4 snaps on a stud 6 to position the cap in the contact insertion / extraction position, the lever remaining in an inclined position for which a rear wing 10 of the lever protrudes from the external bulk of the cap to interfere with an advanced portion 16 of the complementary connector element 12. The first locking finger is here secured to the lever carrying a second locking finger, but can in an alternative version be dissociated of the lever.

Pour interdire l'accouplement des éléments de connecteur, le dispositif comporte des moyens de butée effaçables s'opposant à l'accouplement de l'élément de connecteur avec l'élément de connecteur complémentaire tant que la coiffe n'est pas encliquetée dans la position de verrouillage des contacts sur le module c'est à dire tant que la coiffe est hors position de verrouillage des contacts.To prohibit the coupling of the connector elements, the device comprises erasable abutment means opposing the coupling of the connector element with the complementary connector element until the cap is snapped into the position. locking contacts on the module that is to say as long as the cap is off the contact locking position.

Selon l'exemple de réalisation des figures 3A à 3C, les moyens de butée 5 effaçables sont constitués par l'extrémité de l'aile 10.According to the example of realization of FIGS. 3A to 3C the erasable abutment means 5 consist of the end of the flange 10.

Cette aile est une aile de manoeuvre du levier, opposée à une seconde aile du levier porteuse des doigts de verrouillage 4, 5 par rapport à un point 21 de rotation du levier 14.This wing is an operating wing of the lever, opposite to a second wing of the lever carrying the locking fingers 4, 5 with respect to a point 21 of rotation of the lever 14.

Dans la position des figures 2A et 3B, l'aile 10 interfère avec la partie avancée 16 de l'élément de connecteur complémentaire 12 et interdit l'accouplement des éléments de connecteur 11, 12.In the position of Figures 2A and 3B , the wing 10 interferes with the forward portion 16 of the complementary connector member 12 and prevents coupling of the connector members 11, 12.

Dans la figure 3A la coiffe 1 est pré-montée sur le module 2, en figure 3B, la coiffe 1 est en position d'insertion extraction des contacts.In the figure 3A the cap 1 is pre-mounted on the module 2, in figure 3B , the cap 1 is in the insertion position of the contacts.

Comme indiqué précédemment, l'exemple des figures 3A à 3C est un dispositif comportant deux doigts de verrouillage, le doigt 4 pour la position d'insertion/extraction des contacts, le doigt 5 pour la position de verrouillage des contacts.As mentioned earlier, the example of FIGS. 3A to 3C is a device comprising two locking fingers, the finger 4 for the position of insertion / extraction of the contacts, the finger 5 for the locking position of the contacts.

Pour atteindre la position de verrouillage des contacts représentée en figure 3C, il faut pousser la coiffe 1 tout en appuyant éventuellement sur les ailes de manoeuvre 10 jusqu'à ce que le doigt de verrouillage 5 s'encliquète derrière le plot 6 après passage sur le plot 6 dans un logement de maintien de la coiffe 1, ce logement étant ici constitué par l'espace derrière le plot 6.To reach the contact locking position shown in figure 3C , it is necessary to push the cap 1 while possibly pressing on the maneuvering wings 10 until the locking finger 5 snaps behind the stud 6 after passing on the stud 6 in a housing for holding the cap 1, this housing here being constituted by the space behind the stud 6.

La coiffe est alors en position de verrouillage des contacts et, dans cette position, le bras 22 porteur du doigt de verrouillage 5 repose sur le plot 6 de sorte 25 que le levier 14 fléchisse et abaisse la première aile 10 en position non interférente avec ladite partie avancée du connecteur complémentaire 12.The cap is then in the locking position of the contacts and, in this position, the arm 22 carrying the locking pin 5 rests on the stud 6 so that the lever 14 bends and lowers the first flange 10 in a non-interfering position with said advanced part of the complementary connector 12.

Ainsi l'accouplement des éléments de connecteur est possible dans la position de verrouillage des contacts et seulement dans cette position.Thus the coupling of the connector elements is possible in the locking position of the contacts and only in this position.

En se rapportant à la figure 6 on constate qu'une fonction de détection de contact mal inséré est réalisée par le dispositif.By referring to the figure 6 it is found that a mis-inserted contact detection function is performed by the device.

En effet, dans le cas d'un contact mal inséré dans son alvéole, le linguet 25 correspondant bute sur le corps du contact et se trouve écarté de sa position encliquetée dans le contact.Indeed, in the case of a poorly inserted contact in its cell, the corresponding pawl 25 abuts on the body of the contact and is spaced from its position snapped into the contact.

Dans une telle situation l'élément de verrouillage 3 de la coiffe bute à son tour contre le linguet 25 ce qui interdit de positionner la coiffe en position de verrouillage des contacts.In such a situation the locking element 3 of the cap in turn against the pawl 25 which prohibits positioning the cap in the locking position of the contacts.

Dans un tel cas, les moyens de butée effaçable comprenant la première aile 10 du levier 14 ne peuvent s'effacer ce qui rend l'accouplement des éléments de connecteur impossible et permet ainsi une détection de mauvaise insertion d'au moins un contact.In such a case, the erasable abutment means comprising the first flange 10 of the lever 14 can not fade, which makes the coupling of the connector elements impossible and thus allows a detection of incorrect insertion of at least one contact.

Une telle réalisation est particulièrement recherchée dans le domaine de l'automobile dans lequel il est souhaité de détecter les mauvais montage sur la chaîne de production en empêchant un montage de connecteurs dont les contacts sont mal insérés.Such an embodiment is particularly sought after in the field of the automobile in which it is desired to detect the bad mounting on the production line by preventing the assembly of connectors with incorrectly inserted contacts.

Un autre mode de réalisation de l'invention est représenté notamment aux figures 5A à 5F.Another embodiment of the invention is shown in particular in Figures 5A to 5F .

Selon ce mode de réalisation, la coiffe 1 comporte aussi un levier 13 de verrouillage et les moyens de butée effaçable comprennent une première aile 9 du levier 13.According to this embodiment, the cap 1 also comprises a locking lever 13 and the erasable abutment means comprise a first wing 9 of the lever 13.

Par contre, selon ce mode de réalisation la première aile 9 est contiguë à un doigt de verrouillage 7 assurant le verrouillage de la coiffe sur le module en position de verrouillage des contacts.By cons, according to this embodiment the first flange 9 is contiguous to a locking pin 7 ensuring the locking of the cap on the module in the locking position of the contacts.

La première aile 9 est ici à l'opposée d'une aile de manoeuvre 15 du levier 13 par rapport à un point de rotation 21 du levier 13 et comporte une proéminence 9a à son extrémité.The first wing 9 is here opposite an operating wing 15 of the lever 13 relative to a point of rotation 21 of the lever 13 and has a protrusion 9a at its end.

Les moyens de butée effaçables comprennent la proéminence 9a de la première aile 9 qui interfère avec une partie avancée 16 de l'élément de connecteur complémentaire et interdit l'accouplement des éléments de connecteur 11, 12 tant que la coiffe n'est pas en position verrouillée sur le module 2.The erasable abutment means comprise the protrusion 9a of the first flange 9 which interferes with an advanced portion 16 of the complementary connector element and prohibits the coupling of the connector elements 11, 12 until the cap is in position. locked on module 2.

Pour ce faire et pour maintenir la première aile 9 en position d'interférence, les moyens de butée comprennent en outre une contre-butée 17 sur le module 2.To do this and to maintain the first wing 9 in the interference position, the stop means further comprise a counter-stop 17 on the module 2.

La contre-butée est positionnée de telle sorte que dans la position d'insertion/extraction des contacts, un segment inférieur de la première aile 9 repose sur la contre butée 17 qui s'oppose ainsi à un fléchissement du levier 13.The counter-stop is positioned so that in the position of insertion / extraction of the contacts, a lower segment of the first wing 9 rests on the abutment 17 which thus opposes a deflection of the lever 13.

Après que la coiffe 1 ait été poussée en position de verrouillage des contacts, le segment est décalé au delà de la contre-butée 17.
la proéminence 9a peut alors s'effacer hors d'interférence avec ladite partie avancée du connecteur complémentaire 12 par fléchissement du levier 13.After the cap 1 has been pushed into the locking position of the contacts, the segment is shifted beyond the abutment 17.
the prominence 9a can then fade out of interference with said forward portion of the complementary connector 12 by bending the lever 13.

Pour conserver une élasticité différenciée entre le doigt de verrouillage 7 et la première aile 9, il a été prévu de séparer la première aile du doigt 7. La première aile comporte deux branches longitudinales 18, 19 et un pontet transversal 20, les branches longitudinales 18, 19 encadrant le doigt de verrouillage 7, le pontet transversal 20 étant situé au dessus du doigt 7.To maintain a differentiated elasticity between the locking finger 7 and the first wing 9, it has been planned to separate the first wing of the finger 7. The first wing comprises two longitudinal branches 18, 19 and a transverse bridge 20, the longitudinal branches 18 , 19 framing the locking finger 7, the transverse bridge 20 being located above the finger 7.

Ainsi, le dispositif selon l'invention peut comporter un premier doigt de verrouillage 4, réalisant l'encliquetage de la coiffe dans la position d'insertion/extraction des contacts, et, un second doigt de verrouillage 5 réalisant l'encliquetage de la coiffe dans la position de verrouillage des contacts sur le module porte contacts, ou, comporter un unique doigt de verrouillage 7 pour réaliser l'encliquetage de la coiffe dans la position d'insertion/extraction et dans la position de verrouillage sur le module porte contacts.Thus, the device according to the invention may comprise a first locking finger 4, realizing the latching of the cap in the position insertion / extraction of the contacts, and a second locking pin 5 effecting the latching of the cap in the locking position of the contacts on the contact module, or, comprising a single locking pin 7 to perform the snapping of the cap in the insertion / extraction position and in the locking position on the contact holder module.

Les versions pour lesquelles l'aile constituant moyen de butée est opposée à l'aile portant les doigts de verrouillage par rapport à un point de bascule 21 du levier permettent de détecter le défaut de positionnement de la coiffe dès le début de la connexion avec l'élément de connecteur complémentaire.The versions for which the wing constituting the abutment means is opposed to the wing carrying the locking fingers with respect to a point of flip-flop 21 of the lever make it possible to detect the defect in the positioning of the cap from the beginning of the connection with the complementary connector element.

La version pour laquelle l'aile formant moyen de butée se trouve du même côté que le doigt de verrouillage permet de réaliser une coiffe de faible encombrement pour laquelle le bras de manoeuvre 15 est protégé dans l'encombrement de la coiffe entre des cloisons 26 longitudinales sur la coiffe. L'invention n'est pas limitée aux exemples de réalisation représentés et notamment le plot 6 peut être sous forme d'une poutre transversale.The version for which the wing forming the abutment means is on the same side as the locking finger makes it possible to produce a cap of small dimensions for which the operating arm 15 is protected in the bulk of the cap between longitudinal partitions 26 on the headdress. The invention is not limited to the exemplary embodiments shown and in particular the stud 6 may be in the form of a transverse beam.

En outre, les positions d'insertion extraction et de verrouillage peuvent être obtenues par encliquetage des doigts dans une succession de logements séparés par des créneaux, par ailleurs, le levier faisant partie des moyens de butée selon l'exemple de réalisation de la figure 5 peut être un levier séparé du levier portant le ou les ergots de verrouillage.In addition, the extraction and locking insertion positions can be obtained by snapping the fingers in a succession of slots separated by slots, moreover, the lever forming part of the stop means according to the embodiment of the invention. figure 5 can be a lever separate from the lever carrying the locking pin or pins.
